Combined clamp for drilling hole of torque tube assembling unit product

Abstract

The invention relates to a combined clamp for a drilling hole of a torque tube assembling unit product. According to the technical scheme adopted by the invention, a support I, a movable positioning support base and a shouldered nut I are sequentially arranged on an extension plate I; the movable positioning support base is connected with a cylinder positioning pin; ribbing angle iron I, ribbing angle iron II and ribbing angle iron III are fixed on a base plate; a support II, a vertical drilling template and an extension pressing plate are sequentially arranged on the ribbing angle iron I; a locking nail is arranged on the extension pressing plate; positioning angle iron is arranged on the base plate; a support III, a key slot folding plate, a special template and a double-sided slot drilling template I are sequentially arranged on the positioning angle iron; a positioning key, a support IV and a connection board are sequentially arranged on the ribbing angle iron II; a support V, a counter-bore type drilling template and a shouldered nut II are sequentially arranged on the ribbing angle iron II; and a hole support and a rotary support are sequentially arranged on the extension plate II; and a double-sided slot drilling template II and a middle hole positioning plate are respectively fixed on two sides of the rotary support. With the adoption of the combined clamp, the repeated design and the assembly of the clamp are reduced, the loss of raw materials is reduced, the product quality is improved and the production efficiency is improved.

Description

technical field [0001] The invention provides a clamp for drilling used for angle and distance position and direction limitation in the process of fixing multiple parts of a torque tube assembly product. Background technique [0002] The torsion tube assembly product is an important part that plays a leading role on the aircraft door. The finished product structure angle is changeable and complex, and the parts have different shapes. Generally, it consists of a torsion tube and various types of rocker arms, locking cams, Lock shaft, journal bearing and other parts. When assembling this product, fixtures must be used to ensure the mutual positional relationship between each part and the torque tube, so as to determine the coordination of the matching assembly process. In the past, such products were all manufactured with special tooling, one tool for each, resulting in great waste. When the process requirements are changed under special circumstances, the fixture cannot be ...

Problems solved by technology

As a result, the manufacturing cost is very high. For example, if the combination fixture is selected, whether it can be used universally (various models), whether the drilling jig structure and orientation, and the limit structure can avoid interference, whether the avoidance space is sufficient, and the stability of the limited data Bottleneck issues such as whether performance can be guaranteed; and due to local structural variability in use, whether it can cause user confusion and errors, and product out-of-tolerance and scrapping phenomena due to improper use are the keys to be solved on this set of fixtures.
