Problems solved by technology

If processed according to the traditional method, when the piston rod is produced in large quantities, (1) the wear and tear of the grinding wheel is too large, and the grinding wheel must be replaced frequently
(2) Operators who are required to debug and maintain centerless grinding machines must have certain technical skills. Once equipment failure occurs, the operator does not debug correctly or the particle size and hardness of the grinding wheel are not matched properly, patterns and scratches are easy to appear on the surface of the piston rod. mechanical damage
higher production costs

Embodiment 1

[0011] Such as figure 1 , 2 As shown, the finish rolling device mainly has two fixed rollers 8 . Wherein the adjustment roller 16 forms an assembly with three roller shafts 9 and keys 10 respectively, and then is packed into the frame 15 bearing holes respectively, and the three rollers are distributed at 120°; Circle 5 and be provided with three rollers and frame 15 to keep the front spacer ring 7 of clearance, rear spacer ring 12, rear bearing spacer ring 13 is installed on the slide plate 14 that can longitudinally move after the above parts are assembled. The processing technology of the piston rod is: machining - rough grinding before rolling - fine grinding before rolling - finishing rolling - electroplating - polishing. The finishing rolling process is as follows: ① install the three-roller finishing rolling device on a machine tool with a rotating power head 1 (including guide rails, slide plates 14 and slide boxes); The size of the outer diameter of the rod is the ...

Abstract

The invention provides a piston rod finish-rolling device of an automobile gas spring and a processing process thereof, which is used for rolling the surface of a piston rod by utilizing a three-roller finish-rolling device and aims to solve the technical problems of reducing the processing flows of the piston rod, decreasing the processing cost and achieving the technical requirement of the surface roughness accuracy. The three-roller finish-rolling device is characterized in that: an upper fixed roller and a lower fixed roller are respectively assembled with three roller shafts and a key to form components which are then mounted into stand bearing holes, wherein the three rollers are distributed at an angle of 120 degrees; a front bearing and a rear bearing as well as a front bearing spacer and a rear bearing spacer which are provided with the three rollers and keep gaps with a stand are arranged on the roller shafts; and the assembled components are assembled on a slide plate capable of longitudinally moving. The processing process of the piston rod comprises the following steps of: mechanically processing, rough grinding before rolling, finely grinding, finishing, plating and polishing. By adopting the finish-rolling process technology, not only the procedure of finely grinding after plating is decreased, and the production cost and the equipment investment cost are reduced, but also the surface roughness of the piston rod in the finish-rolling process technology is improved, therefore, the economic benefits are increased.

Description

technical field [0001] The invention relates to a piston rod finish rolling device for a vehicle gas spring and a processing technology thereof. Background technique [0002] The main key part of the gas spring assembly - the piston rod, its surface quality is required to be smooth, and the surface roughness precision is required to be high, generally Ra0.4μm-Ra0.2μm. With the traditional processing method, there are many processing steps: finishing - rough grinding before plating - fine grinding before plating - electroplating (chrome plating) - fine grinding after plating - polishing. If processed according to the traditional method, when the piston rod is produced in large quantities, (1) the wear and tear of the grinding wheel is too large, and the grinding wheel must be replaced frequently. (2) Operators who are required to debug and maintain centerless grinding machines must have certain technical skills. Once equipment failure occurs, the operator does not debug corr...
