Press fitting device and press fitting method for air spring piston

Abstract

The invention relates to an air spring press fitting device, in particular to a press fitting device and method for an air spring piston in the production process of air springs. The press fitting device is mainly composed of a machine platform, a support, a rotary disc, a drive device and a pressure head, wherein the rotary disc is provided with a cross sliding groove, and a fixing sliding block and a locating sliding block which can slide freely are installed on the sliding groove. The air spring piston is placed on the rotary disc, the position of the sliding block is well adjusted, a rubber bag and upper cover assembly of an air spring is placed on the piston, an infrared probe is adjusted well, it is guaranteed that the size counterpoint relation between an upper cover of the air spring and a connector of the piston is accurate, the air spring is inflated through an air gun, and the edge curling operation of a rubber bag is completed. The press fitting device and press fitting method for the air spring piston have the advantages that only one air source is required, press fitting equipment is simplified, press fitting accuracy is improved, the press fitting method is simple and saves time and labor, and the press fitting operation accuracy is largely improved.

Description

technical field [0001] The invention relates to an air spring pressing device, in particular to a device and a pressing method for pressing an air spring piston in the air spring production process. Background technique [0002] Compared with traditional steel springs, leaf springs and rubber springs, air springs have obvious advantages in vibration and noise reduction, and are widely used in the fields of automobiles and engineering vibration reduction. The air spring mainly has three forms: membrane type, sleeve type and capsule type. The membrane type air spring is mainly composed of an upper cover, a capsule and a piston, and the capsule and the upper cover are usually connected together, which can also be called the capsule upper cover. In the automotive field, there are many types of membrane air springs. [0003] Air spring piston press assembly is an important link in the air spring production process. In the process of installing the membrane air spring and pressi...

AI Technical Summary

Problems solved by technology

[0004] 1. During the press-fitting process, the press-fitting machine needs a special oil source and an oil pump. The oil pump needs to provide the oil cylinder pressure to press-fit the piston. A separate air pump system and corresponding electrical control system are required to inflate the capsule of the air spring. The equipment is relatively complicated, the cost of press-fitting is high, and the press-fitting equipment occupies a large area, and the press-fitting site is limited;

[0005] 2. Special pressure head fixtures and piston fixtures are required. Since there are many types of air springs, the press-fitting process requires frequent replacement of fixtures according to air springs of different sizes and shapes, which increases the manufacturing cost and process time of press-fitting and reduces Increased production efficiency in press-fitting operations
