Bearing producing lathe

Abstract

A bearing producing lathe comprises a guide rail; a planker is arranged on the guide rail; the guide rail is fixedly connected with a fixing plate; the fixing plate is fixedly connected with a hydraulic cylinder; one end of a piston rod in the hydraulic cylinder is connected with a double-threaded screw after penetrating the fixing plate; the double-threaded screw is connected with the planker and the piston rod; universal wheels are arranged at the bottom of the guide rail; each universal wheel comprises a wheel hull, a bracket, a wheel, a rivet and a lock plate; an insertion hole is formed in the bottom surface of each wheel hull; a slot is formed in each bracket; the bottom end of each rivet extends into the corresponding slot after penetrating the corresponding insertion hole; a friction plate is arranged between the bottom of each slot and the bottom end of the corresponding rivet; a first through hole is formed in the part, in the corresponding slot, of each rivet; a fixing groove and a second through hole are formed in the left side wall and the right side wall of each slot respectively; a groove is formed in the outer side wall of each bracket, and is communicated with the corresponding second through hole; each second through hole is communicated with the corresponding first through hole; each first through hole is communicated with the corresponding fixing groove; the right end of each lock plate is clamped in the corresponding groove; the left end of each lock plate penetrates the corresponding second through hole and the corresponding first through hole sequentially, and is arranged in the corresponding fixing groove.

Description

technical field [0001] The invention relates to the field of bearing production and processing, in particular to a lathe for bearing production. Background technique [0002] On conventional bearing turning automatic lathes, the connection between the workbench and the hydraulic cylinder is generally a direct connection, that is, the end face of the hydraulic cylinder is directly connected to the end face of the workbench, and the piston rod is directly connected to the base of the workbench, but there are problems with the direct connection. Since it is impossible to ensure that the vertical and horizontal lines of the workbench and the hydraulic cylinder are consistent, using a rigid direct connection will cause the workbench to slow down or even get stuck when it is moving. The second is that the seals of the hydraulic cylinder will be greatly damaged, causing oil leakage and hydraulic cylinder pressure reduction and other failures.

Problems solved by technology

[0002] On conventional bearing turning automatic lathes, the connection between the workbench and the hydraulic cylinder is generally a direct connection, that is, the end face of the hydraulic cylinder is directly connected to the end face of the workbench, and the piston rod is directly connected to the base of the workbench, but there are problems with the direct connection. Since the vertical and horizontal lines of the workbench and the hydraulic cylinder cannot be guaranteed to be consistent, using a rigid direct connection will cause the workbench to slow down or even get stuck when it is moving.

The second is that the seals of the hydraulic cylinder will be greatly damaged, causing oil leakage and hydraulic cylinder pressure reduction and other failures.
