[0002] Titanium alloys refer to a variety of alloys made from titanium and other metals. Titanium, a key structural metal, is widely used in various fields due to its high strength, corrosion resistance, and heat resistance. Its unique advantages have made it a key player in aviation, aerospace, and medical fields. However, the difficulty of machining titanium alloys has long plagued engineers, leading to the need for a positioning fixture for alloy manufacturing and processing.

[0003] Patent publication number CN215942201U discloses an adjustable fixture for titanium alloy processing, including a fixture body, a replacement component and a disassembly component. The top of the fixture body is provided with a clamping component for clamping the workpiece, and the disassembly component for fixture installation is provided at the left and right ends of the bottom surface of the fixture body.

[0004] In order to solve the problem that the clamping plate is inconvenient to replace, the existing technology uses a rotating positioning bolt to separate it from the second positioning hole in the fixed plate, so that the clamping plate can be removed from the fixed plate. This is convenient for when the clamping plate is worn after long-term use, resulting in unsatisfactory clamping effect on the titanium alloy workpiece, and the clamping effect can be improved by simply replacing the clamping plate. However, manual adjustment may still be required, which in turn leads to reduced processing efficiency. Utility Model Content
