Force-controlled rocking-rolling type rolling sealing machine

Abstract

The invention relates to a force-controlled rocking-rolling type rolling sealing machine. The machine comprises a machine frame, a fixed workbench, a floating workbench, a clamping mechanism, a rotating mechanism, a rocking-rolling type rolling mechanism and a pressing mechanism, wherein the fixed workbench is fixedly arranged on the machine frame; the floating workbench is arranged on the machine frame in a sliding way; the rotating mechanism is arranged on the fixed workbench; the pressing mechanism comprises a sliding plate, an air cylinder, an air cylinder piston rod, an air storage tank, a pressing oil cylinder and a pressing piston rod; the sliding plate is hinged with a swing support; the air cylinder piston rod is hinged with the sliding plate; the pressing piston rod is hinged with a swing support; the air cylinder is fixedly connected with the pressing oil cylinder; the air cylinder is connected with the air storage tank through an air delivery pipe; and the sliding plate is arranged on the floating workbench. The pressing mechanism in which air pressure and hydraulic pressure are combined is used for controlling the compensatory pressure of an automobile vibration isolator in a sealing process. Continuous and stable pressure compensation can be kept in the sealing process of the automobile vibration isolator. In addition, the force-controlled rocking-rolling type rolling sealing machine has a simple structure.

Description

technical field [0001] The invention relates to special equipment for sealing, in particular to a force-controlled pendulum roller type rolling sealing machine for sealing 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 known domestic automobile shock absorber sealing machines are relatively backward, their structures are relatively complicated, and their operability is also relatively cumbersome. The Chinese utility patent No. ZL 02206076.6 discloses a flip-type rolling sealing machine, which includes a frame, two guide columns and two lifting columns arranged on the frame, and a lifting frame connected to the lifting columns. The lower connecting frame and the upper connecting frame connect...

AI Technical Summary

Problems solved by technology

The pressure and gravity of the workpiece to be processed directly act on the rotating spindle first, and then are transmitted to the fourth piston, and the pressure balance is achieved through the air pressure in the air chamber. The pressure in the air chamber is relatively large, and the rotating spindle needs to While transmitting the axial force to the fourth piston, it also needs to rotate relative to the fourth piston, which requires a relatively high assembly relationship between the two, which increases manufacturing difficulties, large force fluctuations, and poor balance. The shock absorber will produce rapid axial displacement, fluctuation and vibration during the rolling sealing process, and it is difficult for the automobile shock absorber to maintain continuous and stable pressure compensation during the sealing process

[0004] In addition, none of the devices disclosed in the above two patents can apply pre-tightening pressure to the workpiece before clamping, pendulum rolling, and rolling, so that the positioning of the workpiece is not accurate, and the automobile shock absorber is in the process of rolling and sealing. The resulting rapid axial displacement, fluctuation and vibration are extremely easy to make the workpiece deviate from the processing position, affecting the processing quality and work efficiency
