Problems solved by technology

[0002] In the machining industry, irregular blank surface positioning is often encountered. Due to its complex shape, inaccurate positioning is prone to occur during processing, resulting in low processing accuracy of the product.
In addition, when traditionally processing products with complex shapes, fixtures need to be replaced frequently, which is complicated to manufacture and has low practical performance. Moreover, frequent replacement of fixtures also prolongs production time and reduces production efficiency.

Embodiment Construction

[0015] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0016] A high-precision positioning fixture includes a horizontal base plate 1 on which a vertical vertical plate 2 is mounted on the upper surface. The innovation of the present invention is: a pressure plate 4 is installed on the top of the vertical plate, one end of the pressure plate is hinged on the mounting seat 7 through the pivot pin 8, and the other end is mounted on the other mounting seat of the vertical plate by the fastening screw 3. The pressing plate is arranged parallel to the vertical plate, and forms a gap between the vertical plate and the vertical plate where workpieces can be placed. A mounting hole is made in the center of this pressing plate, and a briquetting block 5 is hinged in this mounting hole, and this briquetti...

Description

technical field [0001] The invention relates to a positioning device, in particular to a high-precision positioning fixture suitable for positioning complex-shaped products. Background technique [0002] In the machining industry, irregular blank surface positioning is often encountered. Due to its complex shape, inaccurate positioning is prone to occur during processing, resulting in low processing accuracy of the product. In addition, when traditionally processing products with complex shapes, fixtures need to be replaced frequently, which is complicated to manufacture and has low practical performance. Moreover, frequent replacement of fixtures also prolongs production time and reduces production efficiency. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings of the prior art and provide a new type of fixture that is easy to use, which can accurately position products with complex shapes, ensure product quality, and imp...
