High precision displacement servo thin parts assembly guide groove

Abstract

The invention relates to a high-precision displacement servo thin part assembly guide groove. The high-precision displacement servo thin part assembly guide groove comprises a cover plate, a frame body, laminated piezoelectric ceramic, a guide groove, a press head and a strain gauge force sensor, wherein the cover plate is connected with an upper bottom plate of the frame body; one end of the laminated piezoelectric ceramic is adhered in a positioning groove in the bottom of the cover plate, and the other end of the laminated piezoelectric ceramic is adhered to the press head; the bottom of the press head is connected with the strain gauge force sensor; the guide groove is formed in the bottom of the frame body. According to the high-precision displacement servo thin part assembly guide groove, axial deviation and deformation of a thin part in the guide groove can be effectively limited, and accurate axial guide of the thin part in the guide groove is realized.

Description

technical field [0001] The invention relates to a precision mechanical assembly device, in particular to a high-precision displacement servo thin part assembly guide groove. Background technique [0002] Due to its unique mechanical structure, the axial dimension of thin parts is very small, usually below 0.2mm. In order to ensure better precision at this scale, high-precision machining equipment is required. Expensive production costs are incurred. Many small and medium-sized machining manufacturers in China can only achieve a machining accuracy of 0.01mm, so the same batch of thin parts produced must have a tolerance of ±0.01mm. Autowiring is made difficult by changes in size. The size of the traditional guide groove is fixed. When the axial dimension of the thin part is smaller than the height of the groove, there will be a large gap between the thin part and the guide groove, which will cause the thin part to shift and change direction in the axial direction when movin...

Many small and medium-sized machining manufacturers in China can only achieve a machining accuracy of 0.01mm, so the same batch of thin parts produced must have a tolerance of ±0.01mm. Autowiring is difficult due to size changes

The size of the traditional guide groove is fixed. When the axial dimension of the thin part is smaller than the height of the groove, there will be a large gap between the thin part and the guide groove, which will cause the thin part to shift and change direction in the axial direction when moving in the groove , can not realize the real guide; on the contrary, the thin part is in too tight contact with the guide groove, and the extrusion force is too large, so that the thin part cannot move in the guide groove

Therefore, at present, the assembly of such thin parts is manually operated, using special fixtures, and manually assembled, which consumes a lot of manpower
