Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shock absorber production, in particular to a shock absorber bracket press-fitting production line and a press-fitting method. BACKGROUND

[0002] The automobile shock absorber is one of the most important components in the vehicle suspension system, and its main function is to reduce the vibration and jolt of the vehicle during driving on the road, and to improve the driving comfort and vehicle stability. The shock absorber bracket is located at the lower end of the shock absorber and is connected with the wheel swing arm for fixing the shock absorber. The common shock absorber bracket mainly includes a clamping part with an open cylindrical structure, and a mounting part located at the opening of the clamping part. The clamping part is sleeved on the oil reservoir of the shock absorber, and the mounting part can be connected to the wheel swing arm and fixed by bolts, so that the wheel swing arm is connected with the shock absorber.

[0003] During the production of the shock absorber, the shock absorber bracket needs to be press-fitted onto the oil reservoir and then welded. The existing process for press-fitting the shock absorber bracket onto the oil reservoir of the shock absorber is as follows: the shock absorber bracket is placed on the positioning tooling of the press machine workbench by hand, and then the oil reservoir of the shock absorber is placed above the upper opening of the shock absorber bracket, and the press machine is started to press the oil reservoir of the shock absorber into the cylindrical clamping part of the shock absorber bracket. This press-fitting process has low production efficiency, and it is dangerous to hold the oil reservoir of the shock absorber by hand during the pressing process. In addition, according to customer requirements, the oil reservoir of the shock absorber is printed with a rolling character mark, and after the shock absorber bracket is press-fitted onto the oil reservoir of the shock absorber, the orientation of the rolling character mark part is consistent with the design scheme. However, due to human factors, the above-mentioned manual feeding method may cause the orientation of the rolling character mark to be incorrect, resulting in unqualified products. Therefore, it is necessary to develop an automatic production line for press-fitting the shock absorber bracket onto the oil reservoir of the shock absorber. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides a shock absorber bracket press-fitting production line. The shock absorber bracket press-fitting production line of the present application can press-fit the shock absorber bracket onto the oil reservoir of the shock absorber, and has the characteristics of high efficiency and safety. Moreover, the shock absorber bracket press-fitting production line of the present application can ensure that the orientation of the rolling character mark on the oil reservoir is correct, thereby avoiding the production of unqualified products. In addition, the shock absorber bracket press-fitting production line of the present application has universality and can be used for the production of different specifications of shock absorber products. Correspondingly, the present application also provides a shock absorber bracket press-fitting method.

[0006] The shock absorber bracket pressing production line comprises a bracket feeding device, a bracket transfer manipulator, an oil reservoir positioning device, an oil reservoir transfer manipulator, a pressing device, a discharging manipulator and a discharging table. The bracket feeding device comprises a group of feeding modules capable of circulating movement. The feeding module comprises a first carrier and a circumferential positioning mechanism. The first carrier is used for placing a shock absorber bracket. The circumferential positioning mechanism is used for cooperating with the opening part of the shock absorber bracket to position the shock absorber bracket in the circumferential direction. The pressing device comprises a punch press and a translation mechanism arranged on the workbench of the punch press. The translation mechanism comprises a reciprocating drive device, a placing rack and a placing table arranged on the placing rack.

The oil reservoir positioning device comprises a rotating table, a camera and a second carrier arranged on the rotating table. The second carrier is used for placing an oil reservoir, and the camera is used for detecting the rolling character mark on the outer circumferential surface of the oil reservoir.

In addition, the rotating table and the camera are arranged to position the oil reservoir at the feeding station and adjust the circumferential position of the oil reservoir, so as to ensure that the orientation of the rolling character mark on the oil reservoir meets the set requirements and avoid unqualified products.

This specific cyclic feeding mode moves only one set step at a time, ensuring precise positioning and high reliability.

This specific bracket transfer robot consists of multiple cylinders with different functions, featuring simple structure and low maintenance cost.

[0013] As an optimization, in the aforementioned shock absorber bracket press-fitting production line, both the oil reservoir transfer robot and the unloading robot are gantry robots. Gantry robots are driven by servo motors, featuring rapid response and precise positioning, enabling efficient production and accurate operation.

[0014] Furthermore, in the aforementioned shock absorber bracket press-fitting production line, the oil reservoir transfer robot includes a B-lifting cylinder and a B-parallel finger cylinder. The B-parallel finger cylinder is equipped with a pair of clamping blocks for clamping the oil reservoir, and the B-lifting cylinder drives the B-parallel finger cylinder to move up and down. This specific oil reservoir transfer robot consists of multiple cylinders with different functions, and features a simple structure and low maintenance cost.

[0015] Furthermore, in the aforementioned shock absorber bracket press-fitting production line, the unloading robot includes a C-type lifting cylinder, a rotary cylinder, and a C-type parallel finger cylinder. The C-type parallel finger cylinder is equipped with a pair of clamping parts for the press-fitted workpiece.
