Connecting rod type fine adjustment mechanism

Abstract

The invention belongs to the technical field of polishing fine adjustment and correction, and discloses a connecting rod type fine adjustment mechanism, comprising: a sliding table capable of moving along the Y axis. a Y-axis driving device which is used for driving the sliding table to move along the Y axis and comprises a first motor and a first connecting rod assembly which are sequentially connected from top to bottom along the Z axis, the first motor driving the sliding table to move through the first connecting rod assembly; a sliding plate which can move along the Z axis and is in sliding fit with the outer side of the sliding table; and a Z-axis driving device which is used for driving the sliding plate to move on the sliding table along the Z axis and comprises a second motor and a second connecting rod assembly which are sequentially connected along the Y axis, the second motor driving the sliding plate to move through the second connecting rod assembly. In conclusion, the connecting rod assembly swings to drive the sliding structure connected with the connecting rod assembly to move, so that fine adjustment is achieved on the corresponding Y-axis and Z-axis. The fine adjustment mechanism has the advantages of being simple in structure, reasonable in assembly, low in cost and high in fine adjustment precision.

Description

technical field [0001] The invention belongs to the technical field of grinding fine adjustment and correction, and in particular relates to a link type fine adjustment mechanism. Background technique [0002] In the existing market, in order to improve the machining accuracy of the workpiece after processing, most of the workpiece surface needs to be polished; specifically, it is necessary to use the corresponding grinding equipment when performing the grinding treatment, and when using the grinding equipment in actual grinding, the main The workpiece is fixed on the fixture, and then the grinding is completed by the relative rotation between the grinding head and the workpiece. However, after the grinding equipment has been grinding for a long time, there will be a certain positioning deviation between the grinding head and the fixture. If the deviation is not corrected, the grinding accuracy of the workpiece will be affected. [0003] In the prior art, the adjustment of ...

Problems solved by technology

However, after the grinding equipment runs for a long time, there will be a certain positioning deviation between the grinding head and the fixture. If the deviation is not corrected, it will affect the grinding accuracy of the workpiece.

[0003] In the prior art, the adjustment of the above-mentioned deviation includes two methods: manual correction and automatic correction. Among them, manual correction has the problems of troublesome operation and low correction accuracy, while the correction structure of automatic correction is relatively complicated, so it also improves The cost of the overall grinding equipment
