Force control rocking-rolling type rolling sealing machine tool

Abstract

The invention relates to a force control swinging grinding type rolling pressing sealing machine tool, which comprises a four guide pole machine frame, a swinging grinding rolling pressing mechanism and a clamping device arranged at the two sides of the cover board of the four guide pole machine frame in a hanging way, and a buoyancy rotation table arranged on the working board of the four guide pole machine frame. the swinging grinding rolling pressing mechanism is arranged at one side of the cover board of the four guide pople machine frame in a hanging way, allowing the axis of the rolling pressing roller of the swinging grinding pressing mechanism meet the axis of the roation table. At least two clamping pieces of clamping device is arranged at another side of the cover board of the four guide pole machine frame in a hanging way, allowing the clamping center of the three rollers at the outer end of the clamping device to be on the axis of the buoyancy rotation table. The invention provides convenient adjustment and control to the sealing pressure of an auto shock absorber, and has excellent tolerance to the axial displacement and fluctuation during the course of rolling pressing sealing, paving the way for a reasonable pressing onto the sealing surface; at the same time a tight pulling of an outer cylinder relative to an inner cylinder is realized; the invention also realizes the convenient adjustment and automatic center positioning while shifting to process working pieces with different specifications and diameters.

Description

Technical field [0001] The invention belongs to a kind of special equipment for sealing, and particularly relates to a force-controlled pendulum rolling-sealing machine tool for automobile shock absorbers. Background technique [0002] The sealing process of automobile shock absorbers is an important link in the manufacture of automobile shock absorbers, and the sealing quality directly affects the performance and quality of automobile shock absorbers. At present, the processing methods and functions of the sealing machines for automobile shock absorbers known in China are relatively backward, and their structure and operability are relatively cumbersome. Now the leading domestic automotive shock absorber sealing machine, such as the flip-type rolling sealer patent, such as the Chinese utility model patent "Flip-type rolling sealer" with the patent number ZL02206076.6 (announcement number CN2535157Y) , Which includes: a frame, two guide columns and two lifting columns arranged on...

AI Technical Summary

Problems solved by technology

The overall structure of the machine tool is relatively complicated, and the adjustment is inconvenient

[0004] The structure of the above-mentioned lifting part is cumbersome; because the automobile shock absorber will produce rapid axial displacement, fluctuation and vibration during the rolling sealing process, the above compensation method is difficult to maintain continuous stability during the sealing process of the automobile shock absorber The pressure compensation, and the volume is large, and the stability of the double oil cylinder is not good; because there are many specifications and different diameters of the automobile shock absorber, and it needs to be controlled within a fixed center range during processing, the above support The clamping method of the fixture is not easy to adjust the center position of different workpieces, and it is not easy to operate; the above-mentioned flipping and rolling method of the rolling wheel does not tighten the outer cylinder of the automobile shock absorber relative to the inner cylinder. , It is easy to cause problems such as loosening of the inner cylinder of the automobile shock absorber during use, which affects the service life and performance of the automobile shock absorber
