Description
Technical Field
[0001] The utility model relates to the technical field of hardware fixtures, in particular to a tooling fixture for fixing and aligning hardware. Background Art
[0002] Before industrialization, hardware installation was usually done manually, with workers using hand tools to install and fix hardware one by one. With the advancement of industrialization, some manual alignment fixtures have emerged. These fixtures help workers align and fix hardware more accurately by adjusting the position and angle of the clamping parts.
[0003] Existing fixtures are usually divided into manual and fully automatic types. When welding pipes, manual fixtures usually use a vise to clamp and fix the two pipes to be welded before welding. However, the clamping surface of the vise is mostly flat. When clamping the pipe, the contact surface between the vise and the pipe body is small, resulting in a general clamping effect. The pipe after clamping is prone to offset and shaking. In addition, the manual type is also troublesome when adjusting the position and angle, with low speed, poor efficiency and low precision. The fully automatic fixture occupies a large area and has a high cost, which is not convenient for small and medium-sized enterprises to promote and use. For this reason, we have launched a fixture for hardware processing to solve the above problems. Utility Model Content
