A Universal Joint Cage Cylindrical Grinding Machine

Abstract

The invention discloses a cylindrical grinding machine for a universal joint cage, which comprises a base plate, the four corners of the lower end of the base plate are provided with shock absorbing devices, and both sides of the upper end of the base plate are fixed with first storage boxes. An auxiliary rotation device is provided in the first placement box, first support plates are fixed on the opposite side of the two first placement boxes, a third through hole is provided on the first support plate, and a third through hole is provided through the third through hole. There is a second storage box, a clamping device is arranged in the second storage box, one side of the auxiliary rotation device is fixed on one end of the clamping device, an adjustment device is provided in the clamping device, and the bottom plate Two second supporting plates are fixed, and the upper ends of the two second supporting plates are jointly fixed with a first fixing block. The invention solves the problem that the cage cannot be fully fixed and clamped, and it is inconvenient to rotate, and assists the grinding through the transformation of the cylindrical grinding machine for the universal joint cage, and the tool has a certain adjustment, which is convenient Use, suitable for promotion.

Description

technical field [0001] The invention relates to the technical field of cylindrical grinding machines, in particular to a cylindrical grinding machine for a universal joint cage. Background technique [0002] The grinding accuracy of the outer circle of the universal joint cage is the key to determining the product quality, and the key to determining the accuracy of the outer circle of the cage is the grinding equipment. Due to the special structure of the cage, the grinding of its outer circle requires special equipment. The existing cylindrical grinding equipment with a cage is composed of a body, a fixed plate, a workpiece support frame, a workpiece bracket, a grinding wheel, and a workpiece top frame, and the fixed plate, the workpiece bracket, the grinding wheel, and the workpiece top frame are fixed. Installed on the fuselage, the workpiece rest is fixedly installed in the end face of the fixed plate. During grinding, the cage is press-fitted on the workpiece support ...

AI Technical Summary

Problems solved by technology

Its main disadvantage is: the workpiece top frame uses a cylindrical contact point welded with a hard alloy material at the end of the ejector rod to contact the outer circular surface of the cage. During the high-speed rotation of the cage, the contact point of the workpiece top frame will be worn. At the same time, the outer circular surface is ground by the grinding wheel, which reduces the contact force between the workpiece top frame and the cage, and affects the grinding accuracy.

Moreover, during the grinding process, the cylindrical contact point of the cemented carbide material at the end of the top frame of the workpiece will scratch the outer surface of the cage, reducing the surface grinding accuracy. The existing cylindrical grinding machine cannot correct the cage Fully fixed clamping, and inconvenient to rotate, auxiliary grinding, can not move the tool conveniently, and play a certain shock absorbing device during the movement of the device
