A rotary cylinder is arranged on the mounting plate, a die clamping seat is arranged on the rotary cylinder, positioning dies are arranged on the die clamping seat, and workpiece embedding grooves are formed in the positioning dies; a reference positioning slide rail is arranged on the mounting plate, positioning sliders are arranged on the reference positioning slide rail, reference positioning blocks are arranged on the positioning sliders, reference positioning cylinders are arranged on the mounting plate, piston rods of the reference positioning cylinders are connected with the positioning sliders, detection yielding cylinders are arranged on the mounting plate, detection positioning cylinders are arranged on the detection yielding cylinders, displacement detection frames are arranged on piston rods of the detection positioning cylinders, and displacement detection devices are arranged on the displacement detection frames; pliers are arranged on the mounting plate and are positioned at the rear side of the die clamping seat, jaws of the pliers are positioned above the workpiece embedding grooves, a support frame is arranged on the mounting plate, pliers driving cylinders are arranged on the support frame, and piston rods of the pliers driving cylinders are hinged to handles of the pliers. The automatic grinding fixture has the advantages that the automatic grinding fixture is simple in structure, convenient to use and high in production efficiency, and the labor intensity can be relieved.

Description

technical field [0001] The invention relates to the technical field of auxiliary accessories for numerical control machining, and in detail is an automatic grinding fixture for numerical control machine tools with simple structure, high degree of automation, convenient use, high positioning and repeat positioning accuracy, reduced labor intensity and high production efficiency. Background technique [0002] Currently, grinding or grooving of workpieces is usually accomplished by manual clamping close to the grinding wheel. During the grinding process, repeated measurements are required to ensure the processing requirements. This method not only increases the labor intensity of the staff, but also depends on the experience of the staff to determine the amount of grinding during the grinding process, thereby reducing the accuracy of clamping positioning and repeated positioning, and it is difficult to maintain the consistency of multiple workpieces. , and reduce the processin...

AI Technical Summary

Problems solved by technology

However, although the numerical control of the grinding equipment, especially the feed axis, has been perfected, the supporting fixtures are still stagnant, and workers still need to clamp a single piece to adjust the positioning of the workpiece, which is time-consuming and laborious, and it varies from person to person. Processing error

Therefore, the automation and precision of the fixture has become the main problem that is difficult to overcome at present, especially for multiple workpieces that need to be ground symmetrically on both sides, the labor waste is serious
