Abstract
Description
Technical Field
[0001] The utility model relates to a floating type automobile accessory welding tool, belonging to the field of automobile accessory processing equipment. Background Art
[0002] Auto parts are the various units that make up the whole car and are a kind of product that serves the car. The shapes and angles of auto parts are mostly irregular. A small number of auto parts can be used as accessories by using stamping dies or cast iron mold casting processes. Most auto parts need secondary processing; as shown in the attached manual Figure 1 The auto parts shown are welded from three auto parts. Since the welding point is in area A and needs to be rotated at a certain angle to continue welding, the three auto parts are welded into a whole. However, Figure 2 As shown, the B surface of one of the automobile parts is an inclined surface.
[0003] Therefore, when welding while rotating, if a traditional fixture is used on the B side, the B side will be partially suspended and cannot be completely fitted and fixed. If the welding force of the welding gun increases, welding offset will occur, resulting in unqualified auto parts and inability to be assembled on the car.
[0004] Therefore, the utility model provides a floating automobile accessory welding tool suitable for fixing an inclined surface. Utility Model Content

[0044] That is, the first cylinder 404 is operated to raise or lower the fixing bracket 401 fixed on the free end of the first power arm 402 of the first cylinder, thereby adjusting the height of the floating fixture 10 to achieve mechanized fixation.
[0045] Furthermore, the fixing bracket 401 includes a first fixing portion 411 and a second fixing portion 412, and the first fixing portion 411 and the second fixing portion 412 are an integrated structure perpendicular to each other. The connection between the first fixing portion 411 and the second fixing portion 412 is fixed to the free end of the first power arm 402 by bolts, and a floating clamp 10 is installed at the free end of the first fixing portion 411.
