Problems solved by technology

Due to the irregular shape and large number of these parts, welding often requires multiple positioning and welding to complete. Not only is there a lot of preparation work before processing, the efficiency is low, and the welding position is not accurate, and the qualified rate of the product is low.

Embodiment Construction

[0023] Referring to accompanying drawings 1 to 6, a welding fixture for an elbow assembly includes a base frame 8, a support mold 9 fixedly arranged on the base frame 8 and supporting the workpiece to be welded, and partially pressed against the workpiece to be welded. A plurality of clamping devices 10 for fixing workpieces to be welded on the surface. A plurality of supporting molds 9 are distributed on the base frame 8 according to the direction of the right curved pipe 6 , and support the right curved pipe 6 .

[0024] The clamping device 10 includes a first cylinder 32, the first cylinder 32 has a first piston rod 33, the end of the first piston rod 33 is rotatably connected with a swing arm 34, and the end of the swing arm 34 is fixedly connected with a pressure head 35 . When the first cylinder 32 is driven, it can control the first piston rod 33 to move, so that the swing arm 34 rotates around the hinge, and the pressure head 35 rotates with the swing arm 34 and can b...

Abstract

The invention relates to a welding fixture of bent pipe components, which comprises a pedestal, a supporting module fixedly arranged on the pedestal and used for supporting workpieces to be welded, and a plurality of clamping devices with the parts clamped on the surfaces of the workpieces to be welded used for fixing the workpieces to be welded. A cylindrical positioning block is fixedly arranged at the front part of the pedestal, and an oil tank pressure plate fixing seat is arranged at the rear part of the pedestal; a power hanging frame fixing seat is also fixedly arranged between the oil tank pressure plate fixing seat and the positioning block; and a branch pipe fixing seat is also fixedly arranged on the pedestal in front of the power hanging frame fixing seat. The welding fixture can rapidly position and clamp components to be welded, thereby avoiding the complex preparatory work before welding, so as to allows the multi-step welding during the one-time process of clamping, and improve work efficiency; meanwhile, the invention can ensure accurate positions among the components when welding, and improve processing precision and qualified rate of the product.

Description

technical field [0001] The invention relates to a welding jig for an elbow assembly, in particular to a tool for clamping and positioning a left or right elbow and other welding assemblies when welding a motorcycle frame. Background technique [0002] The bottom frame of the motorcycle has a left curved pipe and a right curved pipe for supporting the car body. When welding the frame of the motorcycle, the fuel tank pressure plate fixing plate, the power hanger assembly, and the rear pedal branch pipe are usually welded on the left curved pipe. On the right elbow, in addition to the above parts, an ignition coil mounting plate, an oil tank mounting plate and a U-shaped piece are welded, see accompanying drawing 7. Due to the irregular shape and large number of these parts, welding often requires multiple positioning and welding to complete. Not only is there a lot of preparation work before processing, the efficiency is low, and the welding position is not accurate, and the q...
