Crank press ball head screw and spherical bowl combined grinder

Abstract

The invention provides a crank press ball head screw and spherical bowl combined grinder. The grinder comprises a power source, a ball head driving mechanism and a spherical bowl driving mechanism, wherein the spherical bowl driving mechanism comprises a gear and worm mechanism, a second belt pulley, a spherical bowl support and a bowl opening baffle; grinding sand is placed in a spherical bowl cavity; a ball head end of the ball head screw is placed at the spherical bowl cavity and comprises a ball head and a ball head cover plate at the rear of the ball head; the bowl opening baffle limits the ball head end; the spherical bowl support rotates synchronously along with a worm gear; a worm of a gear and worm mechanism is connected with the second belt pulley and is driven by the second belt pulley; the ball head driving mechanism comprises a support, a third belt pulley and an eccentric connecting rod mechanism; the eccentric connecting rod mechanism drives the support to swing in a reciprocating manner; a positioning frame is arranged at the upper edge of the support; a positioning through hole is formed in the positioning frame; the body of the ball head screw penetrates in the positioning through hole; and when the support drives the body to swing, the ball head rotates at the bowl cavity in the left-right direction. The crank press ball head screw and spherical bowl combined grinder can be used for rapidly grinding the ball head of the ball head screw and the spherical bowl cooperated with the ball head.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a crank press ball head screw and ball bowl combined grinding machine. Background technique [0002] The ball screw is one of the main parts of the crank press. The contact quality between it and the spherical surface of the ball directly affects the precision and service life of the press. However, grinding the spherical surface is laborious and time-consuming, and the traditional grinding accuracy is low. Therefore, a A high-precision and fast grinding device for such workpieces is very meaningful for improving the precision and service life of the press. Contents of the invention [0003] The present invention proposes a crank press ball screw and ball bowl combined grinding machine, which can quickly grind the ball head of the ball screw and the ball bowl that cooperates with the ball head. [0004] The present invention adopts the following technical solutions. [0005] Crank pres...
