A pressure gauge dovetail pointer surface treatment device

Abstract

The invention provides a pressure gauge dovetail pointer surface treatment machining device. The device comprises a bottom plate, a grinding mechanism and a polishing mechanism; the polishing mechanism is arranged on the front end of the bottom plate, the grinding mechanism is arranged on the rear end of the bottom plate, and the grinding mechanism is a bilateral symmetry mechanism. The problems that in the pressure gauge dovetail pointer surface machining treatment process, during machining of a dovetail pointer, due to the grinding angle, left-right asymmetry is caused, and indication deviation is caused in the actual use process; in the pointer primary machining, the thickness is not uniform, the point surface cannot be rubbed down, the surface machining device on the market is low in operation efficiency, and large-batch production efficiency is low are solved. The function of improving the dovetail pointer quality is achieved, and the device has the advantages that during machining, the grinding angle can be easily controlled, pointer bilateral symmetry is ensured, the pointer thickness is uniform, and machining efficiency is high.

Description

technical field [0001] The invention relates to the technical field of mechanical production and processing, in particular to a surface treatment and processing device for a dovetail pointer of a pressure gauge. Background technique [0002] The dovetail pointer of the pressure gauge is a pointer similar to the shape of a swallow's tail. Its function is to indicate the size of the pressure scale, which is convenient for the staff to read accurate data. The pointer of the pressure gauge is required to be light in weight, smooth in surface and sensitive in use, because The quality of the pointer is related to the accuracy of the scale display and affects the function of the pressure gauge. [0003] In actual production, the surface of the initially processed pointer needs to be further processed to improve its quality, but in the actual production process of its surface, there are mainly the following problems: a. The dovetail pointer is processed due to the grinding angle Th...

Problems solved by technology

[0005] In order to solve the above problems, the present invention provides a pressure gauge dovetail pointer surface treatment device, which can solve the problems existing in the surface processing of the pressure gauge dovetail pointer: a. The problem of the grinding angle of the dovetail pointer during processing As a result, it is asymmetrical, and there is an indication deviation in actual use; b. Due to the uneven thickness of the pointer during initial processing, the surface of the pointer cannot be ground flat; c. The operating efficiency of the surface processing device on the market is low, resulting in mass production efficiency It can realize the function of improving the quality of the dovetail pointer, and has the advantages of easy control of the grinding angle during processing, ensuring left-right symmetry of the pointer, uniform thickness of the pointer and high processing efficiency.
