Machining clamp of cylinder cover blank adopting robot feeding and discharging mode

Abstract

The invention discloses a machining clamp of a cylinder cover blank adopting a robot feeding and discharging mode, and relates to the technical field of tool clamps. The machining clamp comprises a clamp body, a positioning assembly, a clamping element and an equipment control system, and a lifting supporting plate assembly is arranged at the upper end of the clamp body; and the lifting supportingplate assembly comprises a supporting plate, a supporting mounting base, a cushion block, a thick guide nail, a guide rod and a linear air cylinder, a connecting rod is arranged between the supporting plate and the linear air cylinder, and a nut is arranged between the supporting plate and the connecting rod. According to the machining clamp of the cylinder cover blank adopting the robot feedingand discharging mode, the equipment control system can judge whether a workpiece exists on the clamp body or not through a workpiece existence detection device and keep communication with a robot, sothat machine collision caused by repeated feeding can be prevented, and the problems that because a traditional hydraulic clamp cannot conduct timely information interaction, the workpiece is possiblyclamped, and a collision accident occurs between the hydraulic clamp and the workpiece are solved.

Description

technical field [0001] The invention relates to the technical field of jigs, in particular to a jig for processing cylinder head blanks in a robot loading and unloading manner. Background technique [0002] At present, CNC machining centers and hydraulic fixtures have been widely used in cylinder head machining production lines. The loading and unloading methods of cylinder head blanks are usually manually transported and loaded, or manually pushed to the hydraulic clamps of the machining center with the help of loading and unloading tables. , and after the visual and hand inspection is correct, start the processing. More and more production lines have begun to apply intelligent manufacturing, and the manual loading and unloading of cylinder head blanks has gradually been replaced by truss robots and industrial robots. The collision accident between the holding workpiece and the workpiece on the fixture, and the loading and unloading robot grabs the cylinder head and positi...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a processing fixture for the cylinder head blank that adopts the robot loading and unloading method, so as to solve the problem that the existing traditional hydraulic clamp proposed in the background technology may cause robot clamping due to the untimely information interaction with the loading and unloading robot. The collision accident between the holding workpiece and the workpiece on the fixture, and the loading and unloading robot grabs the cylinder head and positions it in the shape of the blank. The casting blank has a large shape error, and it cannot be positioned smoothly when it is transported to the fixture, which seriously affects the normal production of the production line.
