Load sensing guide hydraulic valve rod surface treatment equipment

Abstract

The invention discloses load sensing guide hydraulic valve rod surface treatment equipment, and belongs to the technical field of hydraulic valve rod machining. The equipment comprises a shell, a driving device is fixedly connected to the lower surface of the inner wall of the shell, an output shaft of the driving device is fixedly connected with the lower surface of a driving wheel, the upper surface of the driving wheel is fixedly connected with the bottom end of a first rotating mechanism, and the top end of the first rotating mechanism is fixedly connected with the lower surface of a nut.According to the load sensing guide hydraulic valve rod surface treatment equipment, through the arrangement of a valve body, a piston plate and a sliding block, when a worker grinds the valve body through a grinding column, the valve body is not prone to rotating, primary treatment and secondary treatment are not needed when the treatment equipment grinds the valve body, the valve body machiningtime is shortened, the precision of the ground surface of the valve body is effectively guaranteed, the valve body has the effect of being precisely matched with other parts in the working process, and the service life of the valve body is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of hydraulic valve stem processing, in particular to load sensing and guiding hydraulic valve stem surface treatment equipment. Background technique [0002] With the rapid development of the hydraulic industry, the requirements for hydraulic products and related components are getting higher and higher. The hydraulic valve stems currently produced have very high requirements for size, shape and position tolerances, and surface treatment. [0003] 1. At present, when processing the surface of the load-sensing and guiding hydraulic valve stem, it is often difficult to process the part that clamps the load-sensing and guiding hydraulic valve stem, resulting in the position of the clamping load-sensing and guiding hydraulic valve stem after processing. Secondary processing, but there are errors in the primary processing and the secondary processing, which will easily affect the precision of the load-sensing ste...

AI Technical Summary

Problems solved by technology

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a surface treatment device for the load-sensing guiding hydraulic valve stem, which solves the problem of often clamping the load-sensing guiding hydraulic valve stem when the surface of the load-sensing guiding hydraulic valve stem is processed. The part is difficult to process and process, which leads to the need for secondary processing to clamp the position of the load-sensing pilot hydraulic valve stem after processing, but there is an error between the primary processing and the secondary processing, which is likely to affect the precision of the load-sensing pilot hydraulic valve stem in use. , it is difficult to ensure that the valve body has the effect of precise cooperation with other components during the working process, which leads to the problem that the service life of the load-sensing oriented hydraulic valve stem is greatly shortened
