Problems solved by technology
If it is in the part development batch, this processing method can be carried out, but when the parts are mass-produced, the following disadvantages will be exposed. Then press the milled side, and then mill the remaining side, the use process is cumbersome; 2. The assembly fixture is unstable, the preparation time is long, and the production cycle is delayed; 3. The part error is large, and the size of each part is unstable. Affect product uniformity; 4. The uncertainty of each assembly is large, and the assembly quality is stable, which affects product accuracy
The above phenomena directly lead to delays in the production cycle of parts and decline in product quality in batch production.

The invention discloses a two-hole positioning adjustable milling clamp which comprises a main body base, a rhombic pin, a cylindrical pin, a first washer, a second washer, a nut, a boss cylindrical pin and a positioning pin. The lower part of the main body base is provided with a positioning pin which is used for positioning and installing the two-hole positioning adjustable milling clamp on a milling machine working platform; and the upper part of the main body base is provided with a first boss and a second boss, the height of the first boss is higher than that of the second boss, and the first boss and the second boss are respectively used for placing a large-hole-forming part of a to-be-processed part and a small-hole-forming part of the to-be-processed part. The two-hole positioningadjustable milling clamp provided by the invention solves the problem of one-step machining of the outline of a complex part, improves the machining efficiency of the part, improves the product quality and achieves certain economic benefits. Meanwhile, the technical level and the capability of solving practical problems are improved. Meanwhile, a manufacturing basis is provided for similar parts.
Description
technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a two-hole positioning adjustable milling clip. Background technique [0002] Tie rod parts are structures that often appear in the aviation field. The material has high toughness, is not easy to cut, and is difficult to process. It is widely used in the aerospace field. The machine tool selected for this material has good rigidity, high power (recommended power greater than 10 kilowatts), and a good cooling device. It is required that the tool has high hardness, strength and toughness, and has good wear resistance, oxidation resistance and resistance. Cohesiveness. [0003] In the process of processing the part, the contour of the part needs to be processed. In the past, the processing process was in the form of an assembled fixture, which was positioned with another positioning pin, and then pressed with a pressure plate before processing. If it is ...
