Problems solved by technology
The welding position of this kind of welding equipment is rough, and each valve needs to readjust the focus of the welding machine. The production efficiency is low, the welding consistency is poor, and the welding quality cannot be guaranteed. Moreover, different types of electric EGR valves require different positioning. Tooling, higher production costs

Embodiment Construction
[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0018] A welding device for quickly positioning an electric EGR valve includes a laser welding machine and a positioning tool. The positioning device is fixed on the laser welding machine and is used for positioning and clamping the electric EGR valve to be welded.
[0019] The structure of the positioning tool is as follows: figure 1 As shown, it includes a bottom plate 1, a side plate 4, a guide rail 16, a sliding block 14 and an assembly plate 11. The assembly plate is used to assemble the cylinder 12, the side plate is used to install the slide block of the electric EGR valve to be welded, and the cylinder is used to assemble the electric EGR valve to be welded. The center rod of the electric EGR valve is pressed against the slide block to complete the positioning of the slide block and the center rod.
[0020] The side plate 4 i...

The invention discloses a welding device for quick positioning of an electric EGR valve. The welding device for quick positioning of the electric EGR valve comprises a laser-beam welding machine and a positioning tool, the positioning tool comprises a base board, a side plate is arranged on the left side of the upper end face of the base board, a positioning seat is mounted at the top end of the side plate, and a groove which is used for positioning an electric EGR valve to be welded is formed in one end, far away from the side plate, of the positioning seat. Two parallel guide rails are arranged on the right side of the upper end face of the base board, sliding blocks which are matched with the guide rails in a sliding mode are mounted on the guide rails, upward vertical assembling plates which are used for mounting a cylinder are perpendicularly arranged on the sliding blocks, the sliding blocks are positioned in U-shaped grooves in the center of the guide rails of the base board, the central axis of a cylinder pressure head overlaps the central axis of the positioning seat groove. The welding device for quick positioning of the electric EGR valve is simple in structure, convenient to use, accurate in positioning and high in universality, the sliding block of a welded EGR is used as a positioning basis directly on the basis of the usage of the general laser-beam welding machine, the welding positional deviation caused by clamping variance of valve bodies is eliminated, and welding efficiency is improved.
Description
technical field [0001] The invention relates to a fixture in the field of mechanical equipment, in particular to a welding device capable of fast positioning and clamping. Background technique [0002] The electric EGR valve is a mechatronic product installed on the engine to control the amount of exhaust gas recirculation fed back to the intake system. It has the advantages of precise control and fast response time. The welding quality of the slider and the center rod in the electric EGR valve directly affects the reliability of the valve body performance and the consistency of the stroke. The traditional tooling used for the positioning and clamping of the slider and the center rod is based on the valve body. By fixing the valve body, the location where the slider and the center rod need to be welded is roughly positioned, and then the focus point of the welding machine is adjusted. The procedure is adapted to the initial starting point for welding. The welding position ...
