Abstract

The invention provides a diameter size interchangeable adjustable grinding rod. The diameter size interchangeable adjustable grinding rod comprises a connecting rod, a transmission device, a first pull rod, a second pull rod, a spring bushing and a guide sleeve, wherein a first blind hole is formed in one end of the connecting rod; the first blind hole is in clearance fit with the first pull rod; one end of the first pull rod is in threaded connection with one end of the second pull rod; the guide sleeve is arranged outside the first pull rod and the second pull rod; one end of the guide sleeve is in threaded connection with the connecting rod; the other end of the guide sleeve and the other end of the second pull rod are both inserted into elastic grooves which are formed in the two end surfaces of the spring bushing along the circumferential direction; the other end of the guide sleeve is conical; the first pull rod and the second pull rod are driven to translate axially by the transmission device. The invention also provides a corresponding system. According to the diameter size interchangeable adjustable grinding rod and the system, an adjustable function that the worn diameter can be compensated during a grinding process can be realized; through an interchangeable function, the machining requirements of products with different pore diameters are met.

Description

technical field [0001] The invention relates to a grinding rod, in particular to an adjustable grinding rod system with interchangeable diameters. Background technique [0002] As an important part of the valve sliding pair, the inner blind hole of the shell assembly has high requirements. Different diameters, dimensional accuracy, cylindricity and surface roughness are important indicators that affect the working performance of valves. However, the diameter of the grinding sleeve of the existing grinding rod is easy to wear, and the structure of the grinding rod is simple and does not have a diameter compensation function. Once the diameter is worn out, the grinding sleeve needs to be manually ground, adjusted, and measured continuously during the processing. The skill requirements for the processor are extremely high; the processing efficiency is low. Contents of the invention [0003] In view of the defects in the prior art, the object of the present invention is to p...
