Embodiment Construction

[0029] refer to Figure 1 ~ Figure 4 , the frame assembly welding production line has five stations in sequence, namely: assembling the frame frame parts 12, welding 13, assembling the rest of the accessory parts of the frame 14, welding 15, and finished product off-line 16, of which two welding stations Each adopts double welding robots 4 to implement symmetrical welding.

[0030] Main components: welding robot 4, welding trolley 2, welding fixture transmission line 1, lifting equipment 5, welding station stop device 8, fixture positioning and clamping mechanism 9, servo motor 10, fixture platform 6, fixture replacement trolley 7, and There are control systems. The welding trolley is composed of a large ring gear 17 with an inner diameter of 2500mm, a bearing, a frame, etc., and five stations are equipped with electric and pneumatic quick-plug interfaces.

[0031] The servo motor 10 does not move at the welding station 13. When the welding trolley 2 arrives at the welding s...

Abstract

A welding production line for manufacturing the frame assemblage of motorcycle is composed of welding fixture conveying line with several workstations, welding carriages moving between conveying line and workstations, the welding fixtures following said welding carriages, two welding robots for symmetric welding, two lift units at both ends of welding production line for lifting up the welding carriage, a fixture platform above the welding production line, and a welding fixture exchanging carriage on said fixture platform.

Description

technical field [0001] The invention relates to a welding production line for a motorcycle frame, in particular to a welding production line for a frame assembly that can realize one-time clamping, staged welding, and flexible replacement of clamps. Background technique [0002] The existing technology for producing motorcycle frames generally divides the frame into small parts and welds them separately, then these small parts are combined and welded into various parts, and finally the parts are assembled into a complete assembly. frame. The disadvantage of this technology is that this step-by-step combined welding increases many auxiliary processes, and the welded frame is easily deformed due to too many processes. [0003] At present, some production lines adopt the welding production line of accompanying welding fixtures for welding production. Combined with robot welding technology, it can realize mass production and welding production status of one-time clamping and ba...
