A multi-degree-of-freedom precision grinding device for ball valve balls

Abstract

The invention discloses a multi-degree-of-freedom precision grinding device for a ball of a ball valve, which comprises a bracket, the upper end of the bracket is provided with a support advance mechanism, the left and right front ends of the support advance mechanism are provided with sanding and polishing replacement mechanisms, and the support advance mechanism includes a mounting mechanism. Plate, hollow sliding rod cylinder, spiral groove rod, the upper end of the mounting plate is rotatably connected with a hollow sliding rod cylinder, and the middle end of the hollow sliding rod cylinder is slidably connected with a spiral groove rod. During use, the ball valve ball that needs to be ground and polished is sleeved on the arc support plate Outer surface, then turn one end of the curved sliding rod provided on the hollow sliding rod barrel into the spiral groove provided on the spiral groove rod. The ball valve ball is moved to the middle of the sawtooth replacement plate, which is convenient for the semicircular hollow shell to wrap the ball valve ball, thereby effectively moving the ball valve ball that needs to be sanded and polished to the inside of the semicircular hollow shell.

Description

technical field [0001] The invention relates to the field of ball valves, in particular to a multi-degree-of-freedom precision grinding device for a ball body of a ball valve. Background technique [0002] At present, when sanding and polishing the ball of the ball valve, it is usually necessary to divide the sanding and polishing into two different devices, or to replace the sandpaper and polishing cloth back and forth. It takes a lot of time to replace different equipment with polishing cloth, resulting in low efficiency and long time. In addition, when sanding, it is usually easy to splash or float more iron filings and dust generated during grinding in the operating room, which cannot be alternated. When replacing the sanding and polishing functions, the whole equipment is automatically closed to isolate the dust from the iron filings, which causes the dust to be easily inhaled into the human body or the sanding iron filings splash and hit the operator. SUMMARY OF THE ...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the above technical problems, a multi-degree-of-freedom fine grinding device for ball valve balls is provided. This technical solution solves the existing problem in the background technology mentioned above that when sanding and polishing ball valve balls, it is usually necessary to combine sanding and polishing Divided into two different devices or back and forth to replace the sandpaper and polishing cloth for operation, it is impossible to polish directly after the sanding is completed, and it takes a lot of time to replace the sandpaper and polishing cloth back and forth or to replace different equipment, resulting in low efficiency and long time. In addition, when sanding, it is easy to splash or float a lot of iron filings and dust generated during grinding in the operation room, and it is impossible to automatically close the whole equipment to remove the dust and iron filings when the sanding and polishing functions are alternately replaced. Insulation, causing dust to be easily inhaled into the human body or the sand and iron filings splashing on the operator will cause problems
