Description

Pneumatic cover pressing jig for SMB 90-degree elbow Technical Field The invention relates to the technical field of 3C electronic and hardware plastic accessories, in particular to a pneumatic cover pressing jig for an SMB 90-degree elbow. Background The SMB 90-degree elbow connector is widely applied to radio frequency communication equipment, test instruments and various electronic products, has a compact structure and has higher requirement on the press-fitting precision of the end cover. In the assembly process, the end cover needs to be accurately pressed into the corresponding position of the connector body so as to ensure the electrical performance and the structural stability of the connector body. Therefore, in the manufacturing process, the end cover is generally required to be pressed by a special tool or equipment, so as to improve the assembly efficiency and ensure the consistency of products. In the field, the assembly of the SMB elbow products is gradually developed from simple manual operation to semi-mechanized tool direction. In the prior art, the press mounting operation of the end cover is generally completed by adopting a manual beer machine matched with a simple positioning jig, and the basic structure of the press mounting device comprises a frame, a manual pressure bar mechanism, a product placing platform and the like. When the assembly fixture is used, an operator places an SMB 90-degree elbow product to be assembled in the fixture, performs preliminary limiting on the product through the positioning structure, then places the end cover at a corresponding position, and utilizes the lever transmission structure of the manual beer machine to drive the pressure head to move downwards so as to apply pressure to the end cover, so that the end cover is pressed into the product to complete the assembly. The structure realizes force amplification by means of mechanical transmission, has the characteristics of simple structure and lower cost, and is applied to small-batch production to a certain extent. However, the prior art has certain disadvantages in the actual use process, namely, the prior art mainly relies on operators to operate through a manual beer machine in the press-fitting process, and the press-fitting position is controlled by experience and hand feeling. Because of the difference of the operation habits and the exertion degrees of different operators, the stable and consistent pressing force and the pressing stroke are difficult to maintain in the continuous operation process, and the deviation of the pressing depth of the end cover is easy to occur. Meanwhile, if the stress is uneven in the press fitting process, the end cover can be slightly inclined or the local stress is overlarge, so that the matching state between the end cover and the product body is influenced. The above situation is more obvious in batch production, and further the consistency and stability of the assembly quality of the product are difficult to effectively guarantee, and the subsequent use performance is influenced to a certain extent. Disclosure of Invention Aiming at the defects of the prior art, the invention provides the pneumatic cover pressing jig for the SMB 90-degree elbow, which solves the problems that the press fitting quality is unstable due to inconsistent press fitting depth and uneven stress of products when the end cover is pressed by a manual beer machine and the press fitting position is controlled by manual hand feeling in the prior art.
