A Fixing Mechanism for Welding Aiming at the Swing Arm Shaft

Abstract

The invention discloses a fixing mechanism for welding of a swing arm shaft. The fixing mechanism comprises a base plate, a mounting base located on the base plate, a sliding block clamping device, a pressure head clamping device and an inner expansion clamping device. The sliding block clamping device comprises a clamping sliding block which is located on the left side of the mounting base and moves leftwards and rightwards. The pressure head clamping device comprises a rear base plate which is arranged on the rear side of the mounting base and moves forwards and backwards. A pressure head rod moving vertically is arranged above the rear base plate. The pressure head rod is arranged vertically. The inner expansion clamping device is located on the right side of the mounting base and comprises a sliding block base, an inclined sliding block and a plurality of lateral sliding blocks. The sliding block base comprises a fixing base of a disk structure and a cylindrical component which is located above the fixing base and internally provided with a cylindrical cavity. The inclined sliding block is of a big-end-up circular truncated cone structure and is located in the cavity. The lateral sliding blocks are clamped on the outer surface of the inclined sliding block and stretch out of notches. Once the inner expansion clamping device fixes the component, a first component will not displace. The clamping sliding block moves rightwards to fix a second component.

Description

technical field [0001] The invention relates to a fixing device, in particular to a fixing mechanism for welding a swing arm shaft. Background technique [0002] The swing arm shaft is one of the spare parts used in the car. Its main function is to support the body and buffer the vibration during driving. The car swing arm is mainly fixed on the car through the swing arm shaft. In order to increase the firmness of the connection between the swing arm shaft and the automobile swing arm, it is considered to fix the structure of the swing arm shaft by welding. [0003] like Figure 1 to Figure 2 Shown is a part of the structure of the right front lower swing arm shaft, which includes a vertically arranged cylindrical structure member 10, a 90-degree bent member 20 and a member 3 30, and member 3 30 includes a horizontally arranged lower side plate and a vertical For the rear side panel, the third component 30 leans against the outer side of the first component 10, and the seco...
