Description

Technical Field

[0001] The utility model relates to the technical field of clamps, and more specifically, to a welding clamp. Background Art

[0002] A fixture refers to a device used to position mechanical parts during the production or measurement process so that the parts meet the position requirements and limit the movement of the parts in space for easy processing. A welding fixture is one type of fixture. During the use of traditional welding fixtures, the accuracy of the clamping block will deviate due to long-term force. At this time, the clamping block needs to be removed from the pressure rod and the gasket needs to be readjusted. During the long welding process, the welding slag easily blocks the hexagonal groove of the bolt, resulting in the clamping block being unable to be removed when it needs to be adjusted, which affects the production progress of mechanical parts to a certain extent. In order to solve the shortcomings of the existing technology, we propose a welding fixture device. Utility Model Content
