Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to an automatic arc welding fixture for automobile parts. Background Art

[0002] In the process of automobile production and processing, some parts are often fastened and installed by riveting. During the riveting process, the parts need to be positioned and fastened to facilitate subsequent processing; there are many ways to position and fasten some curved plates.

[0003] For example, the patent with publication number CN214489747U discloses an arc plate fixture, which drives the positioning plates to move closer to or away from each other through a driving component, and pushes the clamping plate toward the workpiece while positioning the workpiece, thereby positioning and clamping the workpiece.

[0004] However, the curved plate needs to be processed later after clamping, and some of the processing generates large forces, so both horizontal and vertical directions need to be considered. At the same time, the clamping device should not hinder the removal and placement of the workpiece.

[0005] Based on this, the utility model designs an automatic arc welding fixture for automobile parts to solve the above problems. Utility Model Content

[0016] Furthermore, a rivet box for accommodating rivets is fixedly mounted on the carrier.

[0017] The utility model has the following technical effects:

[0018] 1. The utility model rivet gun is suspended on the upper side of the carrier through an elastic connection component. After aligning the through hole on the workpiece with the fixing rod, the top plate of the workpiece is placed on the support block. At this time, the side plate of the workpiece is close to the fixing plate, thereby completing the positioning of the workpiece; the grating sensor is used to detect whether there are people staying on the workbench. After the operator leaves the operating table, the clamping component is started to clamp the workpiece to complete the vertical fixation. At the same time, the fixing rod and the fixing plate complete the horizontal fixation of the workpiece; thereby completing the clamping of the workpiece while ensuring the safety of the personnel; the rivet is installed on the workpiece through the rivet gun;

[0019] 2.
