Fixing device for butt welding process of automobile u-shape coupling

Abstract

The invention provides a fixed device for automobile U-shaped coupling butt weld machining. The fixed device comprises handles, a pull rod, a threaded sleeve, a rotary rod, a bearing seat and a limiting plate; the bottom surfaces of a fixed platform are supported through four upright pillars, two supporting frames left and right are installed between the four upright pillars, and a dreg-acceptinghopper is matched between the two supporting frames in a sliding slot guide rail mode; and a function groove and a threaded rod fixing groove are formed in the front side of the top surface of the fixed platform, a top plate is slidably matched with the interior of a shell cavity through the sliding slot guide rail mode, the top plate can be adjusted and used according to coupling U-shaped seat width dimensions, a coupling is subjected to adjusting supporting through the size of the coupling, and thus the flexibly and practicability are strengthened, and inner sunken grooves are formed in thefront side of a fixed plane, functional rods left and right capable of being rotatably pulled out are installed in the inner sunken grooves, and clamping grooves are formed in the functional rods, byusing the fixed device, welding gun leather hose lines can be supported, and routing of the welding gun leather hose lines is more regular.

Description

technical field [0001] The invention belongs to the technical field of automobile coupling welding tooling structure, and more specifically relates to a fixing device for butt welding of automobile U-shape couplings. Background technique [0002] A coupling is a mechanical part used to connect two shafts (driving shaft and driven shaft) in different mechanisms to make them rotate together to transmit torque. In the high-speed and heavy-duty power transmission, some couplings also have buffer, vibration reduction and improve the dynamic performance of the shaft system. The coupling is welded by a U-shaped connector at one end and a round steel pipe or round steel. The way of passing through the shaft is connected with the transmission parts of the car. [0003] Based on the above description, when processing the coupling, it is necessary to weld the U-shaped piece and the circular section, and in the actual welding, it is necessary to design a fixture to clamp the two segmen...

Problems solved by technology

[0004] In order to solve the above-mentioned technical problems, the present invention provides a fixing device for butt welding of automobile U-shaped couplings to solve the problem that the existing clamping device has a single structure, poor functionality, and in particular cannot be flexibly adjusted. When the coupling is clamped, one-to-one corresponding fixtures are often used, and multi-size adjustable clamping cannot be performed. Therefore, in terms of flexibility and practicability, it should be further improved.
