Two clamping walls are symmetrically arranged. One end of the inner side of the clamping wall is provided with a first electric box, and a first connecting wire is connected to the first electric box. By setting an automobile welding assembly fixture for multi-directional welding, the utility model utilizes the clamping wall, the first electric box, the first socket, the third connecting wire, and the main control center. The robotic arm and the welding assembly arm are respectively installed on the fixing slots of the welding assembly arm, and the power supply is plugged into the first socket. There are three welding arm fixing slots on the clamping wall, and the console of the main control center manipulates the circuits of the three first electric boxes through the third connecting wire, so that the welding assembly arm welds the automobile in multiple directions.

[0004] The above-mentioned welding assembly fixture fixes the outer side plate of the automobile through the clamping of the clamping plate. When the outer side plate of the automobile is offset and needs to be adjusted at a micro angle, it is necessary to loosen the clamping plate, adjust the outer side plate of the automobile, and then clamp it again, which is relatively cumbersome. Summary of the Utility Model

[0005] To improve the above problems, the utility model discloses an automobile welding assembly fixture for multi-directional welding, including two symmetrically arranged clamping walls and a chassis placement table located between the two clamping walls. It further includes: a clamping assembly installed on the inner side of the clamping wall through a telescopic assembly. The clamping assembly includes a side mounting plate connected to the telescopic assembly. A main mounting shaft is installed on the side mounting plate. A suction cup assembly is installed on the housing. An installation groove is provided at the central position of the end of the housing away from the suction cup assembly. The main mounting shaft is installed in the installation groove through a bearing. An electric telescopic rod is installed on the main mounting shaft. The end of the electric telescopic rod away from the main mounting shaft extends into the housing from the inner wall of the installation groove. An inclined groove is installed on the inner wall of the housing. A guiding slider is slidably connected in the inclined groove and is connected to the electric telescopic rod.

[0008] Preferably, a side platform for facilitating the installation of the electric telescopic rod is provided on the main installation shaft.

[0009] Preferably, the suction cup assembly includes:

[0010] Limiting sliding grooves, four limiting sliding grooves are circularly arranged on the front housing, and the grooving direction of the limiting sliding grooves is set to point to the central end of the front housing;

[0011] A guiding circular plate, which is located inside the front housing, and arc-shaped guiding grooves are circularly arranged on the guiding circular plate;

[0012] A guiding rod, which is slidably connected to the limiting sliding grooves and the arc-shaped guiding grooves;

[0013] A vacuum suction cup, which is installed at the end of the guiding rod close to the limiting sliding groove;

[0014] A rotating motor, which is installed on the rear housing, and the guiding circular plate is installed at the output end of the rotating motor.

[0015] Preferably, the front housing is in the shape of a regular octagon.

[0016] Preferably, a fixing nut is installed at the end of the guiding rod close to the arc-shaped guiding groove.

[0019] Compared with the prior art, the utility model has the following advantages:

[0020] For a multi-directional welding automotive welding fixture provided by the utility model, the chassis is placed on the chassis placement table. After the suction cup assembly fixes the outer side plates of the vehicle, the telescopic assembly works, driving the two outer side plates of the vehicle to move towards each other. After the two outer side plates of the vehicle are abutted against the chassis, the welding manipulator can perform welding. When the outer side plates of the vehicle are offset, after the electric telescopic rod expands and contracts, it drives the guiding slider connected thereto to slide in the inclined groove, and then drives the housing connected to the inclined groove to rotate on the main installation shaft, thereby realizing the angle fine adjustment of the outer side plates of the vehicle fixed on the suction cup assembly. In this way, only by expanding and contracting the electric telescopic rod, the angle fine adjustment of the outer side plates of the vehicle fixed on the suction cup assembly can be realized, and thus secondary clamping is not required.

[0031] The working principle and beneficial effects of the above technical solution are as follows:

[0032] The present utility model discloses a multi-directional welding automotive welding fixture. The chassis is placed on the chassis placement table 11. After the suction cup component 16 fixes the outer side plates of the vehicle, the telescopic component 13 works, driving the two outer side plates of the vehicle to move towards each other. After the two outer side plates of the vehicle are abutted against the chassis, the welding manipulator can perform welding. When the outer side plates of the vehicle are offset, after the electric telescopic rod 19 extends and retracts, it drives the guiding slider 21 connected thereto to slide in the inclined groove 20, and then drives the housing connected to the inclined groove 20 to rotate on the main mounting shaft 15, thereby realizing the angle fine adjustment of the outer side plates of the vehicle fixed on the suction cup component 16. For a multi-directional welding automotive welding fixture provided by the present utility model, after the electric telescopic rod 19 extends and retracts, the angle fine adjustment of the outer side plates of the vehicle fixed on the suction cup component 16 can be realized, thus eliminating the need for secondary clamping.

[0033] In one embodiment, the inclined groove 20 is located above the installation groove 17. A connection port communicating with the inside of the housing is provided at the top of the inner part of the installation groove 17. The end of the electric telescopic rod 19 away from the main mounting shaft 15 extends into the housing from the connection port.

[0034] The working principle and beneficial effects of the above technical solution are as follows:

[0035] After the electric telescopic rod 19 extends and retracts, it drives the guiding slider 21 connected thereto to slide in the inclined groove 20, and then drives the housing connected to the inclined groove 20 to rotate on the main mounting shaft 15. Because the electric telescopic rod 19 always maintains a vertical position, the setting of the connection port will not cause movement interference with the electric telescopic rod 19 due to the rotation of the housing.

[0048] The working principle and beneficial effects of the above technical solution are as follows:

[0049] The rotating motor 29 rotates, thereby driving the guiding circular plate 25 installed at the output end of the rotating motor 29 to rotate. With the cooperation of the arc-shaped guiding grooves 26 on the guiding circular plate 25, the guiding rod 27 is driven to slide in the limiting sliding grooves 24 towards or away from the central end of the front housing 22, and further drives the vacuum suction cup 28 installed on the guiding rod 27 to slide towards or away from the central end of the front housing 22. The four vacuum suction cups 28 move towards or away from each other on the front housing 22, thereby realizing the adjustment of the adsorption area of the four vacuum suction cups 28, and thus adaptively adjusting the adsorption area according to the different shapes of the outer side plates of different vehicle models.
