Description

An Auxiliary Mechanism for Welding Composite Bellows Components

technical field

The utility model belongs to the technology and relates to an auxiliary mechanism for welding composite bellows components.

Background technique

The general composite bellows assembly structure is shown in Figure 1. It consists of four main parts: the upper cover 8, the lower cover 5, the bellows 7, and the spring 6. The length of the spring is several millimeters longer than the length of the bellows. During the combined welding process Put the upper cover 8, the lower cover 5, the bellows 7, and the spring 6 on the tin plate 11 of the bow frame 12 as shown in Figure 2, and compress the upper cover 8 and the lower cover 5 through the pressure rod 9 to close the spring 6 In the bellows 7 and tightening the locking screw 10 to form the composite stiffness of the spring plus the bellows, the spring 6 is under compression in the assembly. The entire compression process is shown in Figure 3.

Contents of the invention

The purpose of the utility model is to provide an auxiliary structure for welding composite bellows components to solve the problem of fixing the welding position during the welding process of the composite bellows components when the composite rigidity is relatively high.

The technical scheme of the utility model is: 1. An auxiliary mechanism for welding composite bellows components, which includes a spacer 1, a sleeve 2, a pull rod 3, and a nut 4; the spacer 1 is two semicircular pads It is embedded in the corrugation of the bellows assembly, and the end surface is in contact with the sleeve 2; one end of the sleeve 2 is open and sleeved outside the bellows assembly, and there is a through hole in the bottom center of the other end, through which the pull rod 3 passes. The tie rod 3 is a bolt with threads at both ends, one end is threaded and connected to the bellows assembly, and the other end passes through the sleeve to connect with the nut 4; the nut 4 is a standard part that is threaded with the pull rod 3 and is located bottom outer wall. Auxiliary mechanism for welding composite bellows assembly, by adjusting the nut 4, the position of the pull rod 3 can be moved, thereby stretching the length of the bellows, making the spring 6 sink into the bellows 7, and thus making the upper cover 8 and the bellows 7 Reliable close contact without the rebound force of the spring 6.

The utility model has the advantages of providing an auxiliary mechanism for welding composite corrugated pipe components, greatly improving the reliability of fixing the parts and ensuring the quality of the processed parts.

Detailed ways

Below the utility model is described in further detail. See Figure 4, an auxiliary mechanism for welding composite bellows components, which consists of a spacer 1, a sleeve 2, a pull rod 3, and a nut 4; the spacer 1 is two semicircular gaskets, which are embedded In the corrugation of the bellows 7 of the bellows assembly, the end surface is in contact with the sleeve 2, which is used to fix one end of the bellows assembly; one end of the sleeve 2 is open and sleeved outside the bellows assembly, and there is a through hole in the center of the bottom of the other end , the pull rod 3 passes through the through hole, and the sleeve 2 plays the role of supporting the bellows assembly; the pull rod 3 is a bolt with threads at both ends, one end is threaded with the threaded connection of the lower cover 5 in the bellows assembly, and the other end Through the sleeve and connected with the nut 4; the nut 4 is a standard part threaded with the pull rod 3, located on the outer wall at the bottom of the sleeve 2, the adjustment nut 4 can move the position of the pull rod 3, thereby stretching the bellows 7 in the bellows assembly The length of the spring 6 sinks into the bellows 7, so that the upper cover 8 and the bellows 7 are in reliable and tight contact without the rebound force of the spring 6.

The working principle of the utility model patent is: the bellows assembly can move the position of the pull rod 3 by adjusting the nut 4 in the auxiliary mechanism for welding the composite bellows assembly, so as to stretch the length of the bellows 7 and make the spring 6 sink into the In the corrugated tube 7, the problem of unreliable contact between the upper cover 8 and the corrugated tube 7 caused by the compressed spring 6 in the original welding fixture is avoided.
