Dispatch of net of machine tool of Chinese numerical control: In exercise process, because of,the person that work often is met careless omission or forget and produce exercise error, the question in the production that causes accordingly is very much, if can use the law that prevent a fault to prevent the happening of this kind of error, criterion product quality standard and exercise efficiency will surely rise considerably. Preventing a fault is to point to try to prevent namely before process error happens, it is one kind uses automatism in exercise process, call the police, the method such as label and classification, make work staff nots only not to notice also won't the method of error. The article is aimed at the problem of train in excess specified length of material of Central Plains of process of the material on the machine tool, clever design gives the unit that prevent a fault, put an end to the happening of the accident from fountainhead, the work that guarantees employee is safe, achieved use the limitative method that avoids to produce a mistake, let handlers do not need to cost attention, also do not need experience and professional knowledge to be able to achieve the goal that operates correctly. 1.

Lathe of numerical control of   of   of the purpose that prevent a fault is a kind of high accuracy, efficient automation machine tool, it is current in machining process most the device that often uses, and in the treatment process that expects for the club in raw material, the application that sends makings plane automatically realized the successive loop treatment of the spare parts, enhanced the automation rate that the spare parts machines, rose to machine efficiency. Security of job of job of the member that the design preventing a fault in expecting on the machine tool is ensured is what the club expects to go up in raw material in material process, because the length of main shaft of numerical control lathe is finite, taboo exceeds the good stuff that length restricts, prevent good stuff to exceed the back end range of shield of machine tool main shaft namely, the good stuff that rotates in the high speed in machining a process otherwise can generate serious safe hidden danger, for this, meeting mark has place of face of back end of machine tool main shaft relevant and safe caution. In actual production, to the limitation of raw material length the dimension in passing craft document asks to come true, but if operate personnel,do not operate by the requirement, in still can putting the raw material that exceeds length requirement machine tool main shaft, can produce serious safe accident so. The raw material of some spare parts restricts the good stuff that is 900mm for length, and the good stuff that employee is length 1200mm is put into main shaft of numerical control lathe, the back end that creates good stuff and send makings machine automatically the contact, in machining a process, good stuff high speed rotates and with send makings machine automatically to produce collision, good stuff bends quickly stage by stage and attack rear of main shaft of broken machine tool relevant accessory, the tremendous vibration of the generation in bumping causes circuit board to become loose, after the machine tool calls the police, stop just now machine. 2.

Course of   of   of the measure that prevent a fault observes not difficult discovery, what be used to according to operating personnel is different, two kinds go up stuff kind: Will good stuff puts ① to send makings machine 2m wide work or material rest, through handle the operation sends makings plane, will good stuff sends lathe main shaft further, expect on work or material rest namely means. ② expects the club to by lathe main shaft front inserts main shaft directly, expect on main shaft namely means. It is which kinds of means no matter, equipment itself all cannot prevent what club of train in excess specified length expects to be put. Of kind of the stuff on the basis different, need designs the corresponding plant that prevent a fault. (1) the measure preventing a fault that is aimed at the makings on work or material rest. To kind of the stuff on work or material rest, think up not hard, the bounds with appropriate setting grows lever can, train in excess specified length is marvellous makings general cannot expect through sending machine work or material rest undertakes going up expecting, install those who be restricted to grow lever to if the graph is shown 3 times,send makings plane. (2) the measure preventing a fault that is aimed at the makings on main shaft. To kind of the stuff on main shaft, the space that expect as a result of the club and sends makings machine action of top makings staff is almost same, preventing bad fit how to undertake distinguishing is the difficulty of the design. Analyse to facilitate, might as well go up in the design principle of the device that prevent a fault, the method that prevent a fault cent is electric prevent fault and machinery to prevent a fault two kinds, if subordinate list place is shown,two kinds of methods that prevent a fault contrast. From two kinds contrast of the method that prevent a fault comes up look, the reliability that prevents a fault in view of machinery is high, preferential by this principle the design prevents wrong plant. In particular function respect, the designs plant that prevent a fault should realize the function of two following respects: ① expects when the club when train in excess specified length, the device that prevent a fault can prevent what the club expects to be put. ② should send makings machine to carry makings lever on the head to withstand when good stuff undertakes sending makings movement, the device that prevent a fault cannot hamper the top expects the movement of lever, carry makings lever on the head to be able to undertake smoothly carrying makings and retractile movement on the head ahead namely. By the analysis knowable, can follow the working principle of one-way a powerful person will design   of   of the device that prevent a fault to be restricted to grow board the crucial part that is the device that prevent a fault, want to have particular strength already, want implementation to appropriate curved knuckle is spent again, such ability safeguard are restricted grow functional dependability. Those who need an attention is, as a result of gravitational action, the in carrying material process on the head meeting after sending makings machine to carry makings lever on the head to extend bends downward, and the bounds of the device that prevent a fault grows board meeting to radial load action goes up at carrying makings lever on the head. Curve degree to reduce those who carry makings lever on the head, when the device that prevent a fault is installed, should assure to be restricted to grow board function cannot be improved on the radial load direction of makings lever. In the use process of the device that prevent a fault, be restricted to grow board fall in the tensile action of bedspring, can maintain in end the position, prevent the good stuff of train in excess specified length to was passed backward once upon a time, grow with time limit board reasonable angle of bend spends a design, made sure the top expects lever extends the success of a makings and retractile movement again. Additional, what should prevent wrong plant is fragile for bedspring, bedspring once invalidation, be restricted to grow board irretentive in spacing position, the device that prevent a fault also will cannot rise to defend wrong action. To avoid this kind of circumstance happening, in the device that prevent a fault two side set two spring, at the same time every half an year will undertake changing to bedspring, reduced the risk of be no longer in force of the plant that prevent a fault so effectively. 3.

Epilogue     designs personnel to should master the skill that prevent a fault in time, give good executive method in the creation in working practice. Field work person should strengthen responsibility heart, the working principle that bad fit designs is defended related proper understanding, discover doubtful point is mirrorred in time to concerned personnel, cannot ignore dismantle the plant that prevent a fault blindly even, avoid the happening of accident of great quality safety. Business management person the application that should take promotion seriously to prevent wrong technology to make whole process in the product, reduce quality problem, eliminate safe hidden danger, implementation company grows a target. Prevent a fault actively only, systematically, use all sorts of technologies that prevent a fault integratedly, ability improves the result that prevents a fault truly. CNC Milling CNC Machining
