Method for connecting and positioning column and carriage of machine tool

Abstract

The invention discloses a method for connecting and positioning a column and a carriage, comprising the following steps: A. processing positions for placing adjusting wedges and glue injection cavities on the contact surface of the fastening surface of the column and the carriage; B. processing glue injection holes, glue exit holes and bolt through holes on the glue injection cavities and simultaneously sealing the surroundings of the glue injection cavity bodies and the bolt through holes with sealing strips; C. cleaning the glue injection cavity bodies with acetone or trichloroethylene before fastening the column and the carriage and coating mold release agents on the contact surface of the carriage; D. fastening the column and the carriage which are already processed in the above steps, pre-tightening fastening bolts in the bolt through holes and adjusting the connecting and positioning precision of the column and the carriage to the specified requirements with the wedges; and E. injecting positioning glue into the glue injection cavities, and after curing for 24h, displaying that the fastening bolts are fastened to the right positions through measurement, thus completing connecting and positioning. In the method, the joint surfaces dispense with scarping, thus improving the rigidity and stability of the machine tool structure.

Description

technical field [0001] The invention relates to the connection and positioning between a movable column and a sliding seat of a large numerically controlled machine tool, in particular to a method for connecting and positioning a column and a sliding seat. Background technique [0002] The traditional connection between the column and the sliding seat is to finish the two joint surfaces first, and to ensure that the combination of the column and the sliding seat is in a vertical state. Since the vertical precision is difficult to achieve in machining, it is often necessary to scrape the joint surface repeatedly. method; even so, the joint surface can only be a partial point contact, which is easy to reduce the stability and rigidity of the machine tool. Using the traditional technology not only has high requirements on the precision of the processing machine tool, but also requires repeated hoisting and turning of the column for scraping and grinding, which is time-consuming...

[0002] The traditional connection between the column and the sliding seat is to finish the two joint surfaces first, and to ensure that the combination of the column and the sliding seat is in a vertical state. Since the vertical precision is difficult to achieve in machining, it is often necessary to scrape the joint surface repeatedly. method; even so, the joint surface can only be a partial point contact, which is easy to reduce the stability and rigidity of the machine tool

Using the traditional technology not only has higher requirements on the precision of the processing machine tool, but also requires repeated hoisting and flipping of the column for scraping and grinding, which is time-consuming and laborious

Therefore, the assembly accuracy of the machine tool depends to a large extent on the operator's technical level and professionalism, which directly leads to the long production cycle of the machine tool.
