Pneumatic bending device for lock catch of optical module sheet metal part

Abstract

The invention discloses a pneumatic bending device for a lock catch of an optical module sheet metal part, comprising a pneumatic element part and a structural part unit, wherein the pneumatic element part is a power mechanism; and the structural part unit is an actuating mechanism. The pneumatic bending device adopts compressed air as a power source, thereby being clean and sanitary; non-contactinstallation exists between an air cylinder and a driving block, and an installation position is adjusted through a strip-shaped hole positioned on a member provided with the air cylinder, therefore the adjustability of the bending depth of a U-shaped lock sheet is realized; a T-shaped groove is prefabricated on a member provided with a thimble, therefore the bends of the U-shaped lock sheet on different positions can be all considered by adjusting the position of the thimble; the air cylinder is provided with a throttle valve so as to not only adjust the movement velocity of the air cylinderbut also close a certain air cylinder, therefore the requirement for single edge bend of the U-shaped lock sheet is met; and a spring structure is used for resetting the driving block pushed by the air cylinder to an initial position and has the functions of shock absorption and noise reduction.

Description

technical field [0001] The invention relates to the field of communication, in particular to a bending device for locking a sheet metal part of an optical communication module (SFP structure). Background technique [0002] In the optical communication module of the SFP structure, the connection between the sheet metal part and the base adopts the structure of the prefabricated U-shaped locking piece on the curved sheet metal part as follows figure 1 and figure 2 two kinds. figure 1 It is a typical case where the U-shaped locking piece 3 is located in the middle of the module, figure 2 It is a typical case where the U-shaped locking piece 3 is located near the gold finger 4 of the module. The core function of the device of the present invention is to bend the U-shaped locking piece 3 so that it can be fastened to the prefabricated part on the base 1, so as to achieve the purpose of connecting the sheet metal part 2 and the base 1, image 3 The state after the U-shaped l...

Problems solved by technology

[0003] In the early production, the U-shaped cleats were bent manually by operators using tweezers. Because of different people and different bending forces, the U-shaped cleats were bent in different depths, and the quality of the shipment was difficult to guarantee. Its low efficiency has also become a bottleneck for increasing production capacity
