Description

Grinding tool mechanism for high-precision numerical control machine tool guide rail grinding machine Technical Field The application relates to the technical field of numerical control machine tools, in particular to a grinding tool mechanism for a high-precision numerical control machine tool guide rail grinding machine. Background In the processing process of the high-precision numerical control machine tool guide rail grinding machine, the stability and the angle accuracy of workpiece clamping directly determine the guide rail grinding quality, and the existing grinding tool mechanism has many defects and is difficult to meet the high-precision processing requirement. At present, the clamping angle of traditional grinding frock is mostly fixed setting, can't adjust in a flexible way according to the grinding demand of different work pieces, and the suitability is relatively poor, needs frequent special frock of changing, increases processing cost and auxiliary time. Meanwhile, the existing limiting mechanism of the clamping structure is unreasonable in design, lacks a reliable angle positioning component, and is easy to cause clamping angle deviation due to vibration during grinding, so that machining precision is affected. In addition, the sliding adjustment mode of grip slipper is crude, and the cooperation precision of second holder and first holder is not enough, easily appears becoming flexible, skew after the work piece clamping, and the cooperation design of fixture block and draw-in groove is imperfect, can't realize the accurate location of angle. In view of the above related art, the inventors consider that there is a defect that looseness and offset easily occur after clamping of an inclined workpiece. Disclosure of Invention In order to solve the technical problems, the application provides a grinding tool mechanism for a guide rail grinder of a high-precision numerical control machine tool. The application provides a grinding tool mechanism for a high-precision numerical control machine tool guide rail grinder, which adopts the following technical scheme: the grinding tool mechanism for the high-precision numerical control machine tool guide rail grinder comprises a machine tool, a guide rail and a knife grinder, wherein the guide rail is arranged on the machine tool in a transversely sliding mode, the knife grinder is arranged above the guide rail, an installation seat is arranged on the guide rail, a first clamping piece is rotatably arranged on the installation seat, an arc-shaped groove is formed in the first clamping piece, a plurality of clamping blocks are slidably arranged in the arc-shaped groove, clamping grooves for accommodating the clamping blocks are formed in the installation seat, the clamping grooves are staggered with the arc-shaped groove, a clamping seat is slidably arranged on the installation seat, and a second clamping piece is rotatably arranged on the clamping seat. Through adopting the technical scheme, through the arc-shaped groove of the first clamping piece, the cooperation structure of the clamping block and the clamping groove of the mounting seat, the limitation of fixing the clamping angle of the traditional tool is broken, the angle of the first clamping piece can be adjusted by rotating according to the grinding requirement of the workpiece, the clamping block can slide into the clamping groove along with the angle adjustment to realize unidirectional limiting, the clamping angle deviation caused by the grinding acting force of the knife grinding in the grinding process is avoided, meanwhile, the stepped accurate regulation and control of the angle can be realized through the cooperation of the clamping groove and the clamping block, the precision grinding processing requirement of the guide rail grinder of the high-precision numerical control machine tool is adapted, and the angle precision and the processing consistency of the workpiece grinding are effectively improved. Preferably, the first clamping piece comprises a clamping main body and a mounting plate which are respectively arranged on the mounting seat in a rotating mode, the clamping main body is connected with the mounting plate, and the arc-shaped groove is formed in the mounting plate. Through adopting above-mentioned technical scheme, separate first holder for mounting panel and centre gripping main part, the mounting panel is arc recess, fixture block complex core vulnerable part, if the problem such as arc recess wearing and tearing appear in the use, can dismantle the mounting panel alone and maintain or change, need not whole first holder of changing, effectively reduce maintenance consumable cost and change man-hour, but simultaneously according to the grinding angle regulation demand of different work pieces, the direct change processing has the mounting panel of different specification arc recess, need not to redesign and process whole centre gripping main part, the different processi
