Summary: Automatic the main part that is numerical control grinder to knife device. After numerical control grinder finishs outfit clip to workpiece, should pass above all be opposite automatically knife system is accurate the place that finds emery wheel treatment to be cut, come true thereby efficient more accurate be opposite automatically knife function. Be opposite automatically in buy of jacket of grinder of of all kinds numerical control knife system, can optimize manufacturing technology better, improve manufacturing efficiency. The article is right automatic to the measurement of knife device principle and configuration undertake an analysis, introduced numerical control to carry cylindrical grinder to be opposite automatically deep knife plant design and grinder of numerical control nut are designed automatically to knife device. Keyword: Numerical control grinder; Be opposite automatically knife device; Fixed position 　 1, analyse numerical control grinder automatically to basically have straight formula and circumgyrate type automatically to the configuration of knife device to the configuration of knife device. Decide really about two kinds of configuration, basically depend on numerical control grinder is spent to the satisfaction that goes up automatically to knife unit position, it is a basis next the respect such as metrical function, accuracy and property volume will undertake deciding. Be opposite automatically no matter knife device is which configuration must the structure is compact, and need is in accurate after measuring, break away from side head the grinding area of numerical control grinder. But, those who need an attention is, the work that cannot affect need grinding holds clip, want to do fine installation to debug, change in time emery wheel, should ensure at the same time be opposite automatically the sealed function of knife device configuration. Normally, numerical control grinder is opposite automatically the means that what the circumgyrate type place in device uses is fluid drive, can realize fixed position of decelerate of data line circumgyrate quickly so, the purpose is to ensure the accuracy that repeats fixed position, maintain the dependability in grinding process and smooth stability. 2, cylindrical grinder of numerical control end panel is opposite automatically knife device 　 2.

The main use of design of position of 1 pair of knives and cylindrical grinder of end panel of methodological numerical control is nut of pair of ball guide screw outside circle and end panel undertake grinding, and be opposite automatically the purpose of knife device is right end panel position undertakes metrical, if pursue,1 is shown. Graph 1 be opposite automatically knife device 　 2.

2 after measuring a principle to analyse workpiece to finish outfit clip, need changes way through the hand correct set is opposite automatically the safe position of rest of the knife. Those who need an attention is, right now side head needs the work of grinding without bring into contact with. After the examination ends, start automatic grinding program. Above all, should wear X axis emery wheel shift to arrive region of place of safety, jut side head come, cut X axis main aspects area directly next, the square along Z axis to begin to have shift. After end panel of side head bring into contact with, the position that system of numerical control grinder can move this is exact the record comes down, return safe place again next. Next, side head still needs to cut small end panel, and the square along Z axis to shift, the position that the system of head contact meets side move the 2nd is exact the record comes down. Finally, before union the data that records twice, undertake be adjustmented finally to the position of side head, workpiece, emery wheel, begin automatic grinding next. Additional, numerical control grinder is opposite automatically the safe safeguard of knife device needs to bring into grinding program, and cogent carry out. For example: The hand moves unit process of cargo bandling in, side head can be exited arbitrarily or call in. But, be in specific in operational course, side head wants to come to issue ability to extend to the circumstance of knife area in X axis and Z shift, other any circumstance side heads cannot be extended. 2.

Design of 3 rigid structures analyses rigid structure to design is basis of manufacturer of machine tool production commonly the real need of machine tool product will design, introduce hydraulic pressure drive, guide pillar guide-post bushing can produce circumgyrate situation commonly in steep drive process, for example: On the machine tool device circumgyrate controls an orgnaization, but integral structure is met more giant. Connect regular meeting to use deputy transmission of linear scroll slideway, divide the freedom beyond sharp movement to spend with can be being controlled better, and the structure is more compact, the fine that in running a course, can keep taller allows to spend, still can promote transmission efficiency. Additional, transform the bracket below to design considering stand-alone, take cast form cost taller, because this chooses soldering way according to actual condition, allow integral construction can more compact, convenient also production, can satisfy better run effective demand point-blank with what hold position gently. 3, grinder of numerical control nut is opposite automatically knife device 　 3.

The main use of design of 1 pair of knives and grinder of nut of methodological numerical control is raceway of whorl of grinding ball nut. In the process that has pair of knives, on the circle outside wanting calibration nut return to implement, want to will aim the centre of gravity of raceway to the knife, the error cannot exceed 0.

03mm, if pursue,to knife position 2 are shown. Graph 　 of position of 2 pairs of knives 3.

2 measure a principle to analyse nut grinder to measure a principle to need to will be opposite the knife is accurate right to workpiece return to implement aperture center. Pair of main knife programs be: Above all, want to had installed workpiece, shift to an earlier date the action position of X axis set is good, jut side head even at the same time come, x axis along square to begin to have shift, head allowing side is entered return to implement central aperture; Next, z axis and C axis must want to part along losing direction to have shift, the system when side head begins lay a finger on begins to record coordinate, general need records 4 coordinate. After the system has data inducing, through computation, can the center of raceway of accurate gauge lay off, undertake Z axis and C axis adjustment next, after obtaining correct helix position, ability begins to undertake automatic grinding. 3.

Grinding machine of nut of analysis of design of 3 rigid structures is automatic rigid to knife device structure needs to satisfy in design process: Above all, side head is in in extending a process, the height of nut grinder and fore-and-aft must keep consistent with emery wheel center on direction; Next, when side head begins withdrawal, the attention should be under end panel of main shaft of emery wheel report; Finally, the dimension of foreign aids of the biggest nut that the transverse distance of head of machine tool upside and emery wheel center should be more than a machine tool to be able to be machined, repeat fixed position precision to cannot exceed 0.

002m. The orgnaization of nut grinder is more complex, the space all round emery wheel wearing is not much also, air cylinder journey should choose 250mm, model is MAL20250SCM, if the graph is shown 3 times,mechanical design structure is designed.
