[0032] Reference below Figures 1 to 3 , the utility model is further described as follows:

[0033] Automatic clamping welding tooling, including:

[0034] Bottom plate 1;

[0035] The support plate 2 includes: a first support plate 21, a second support plate 22, a third support plate 23 and a fourth support plate 24, which are distributed on the bottom plate 1 in a rectangular shape and are fixedly connected to the bottom plate 1;

[0036] The clamping unit 3 is arranged on a side of the third support plate 23 away from the second support plate 22 and is fixedly connected to the bottom plate 1;

[0037] A clamping unit 4, wherein two clamping units 4 are respectively arranged on one side of the first support plate 21 and the second support plate 22;

[0038] The harness support unit 5 is arranged on a side of the connection line between the first support plate 21 and the third support plate 23 close to the edge of the bottom plate 1;

[0039] The stabilizer bar bracket unit 6 is arranged on a side of the first support plate 21 away from the edge of the bottom plate 1;

[0040] The hose support unit 7 is disposed on a side of the connection line between the second support plate 22 and the fourth support plate 24 close to the edge of the bottom plate 1 .

[0041] During welding, two welding main parts are taken and supported by the first support plate 21 and the third support plate 23, the second support plate 22 and the fourth support plate 24 respectively, to ensure that the welding main parts can be stably supported during welding to achieve an ideal welding effect.

[0042] In this embodiment, the automatic clamping welding tool also includes a first limit device 8, which is arranged on the side of the clamping unit 3 close to the hose bracket unit 7 and is fixedly connected to the base plate 1. The upper end of the first limit device 8 is detachably connected to the limit pin 81.

[0043] When the welding main component is placed in the corresponding position, the holes set on the welding main component supported by the second support plate 22 and the fourth support plate 24 will correspond to the position of the first limiting device 8. At this time, the limiting pin 81 just passes through the hole on the welding main component to play a limiting role.

[0044] After the main welding parts are placed, the wire harness bracket, stabilizer bar bracket and hose bracket are placed into the corresponding wire harness bracket unit 5, stabilizer bar bracket unit 6 and hose bracket unit 7 respectively, waiting for welding.

[0045] In this embodiment, the support device 32 is made of I-beams. The I-beams have high strength, which can make the clamping unit 3 stronger and more durable. Moreover, the shape of the I-beams is also convenient for fixation, so that it can be more firmly fixed on the base plate (1) and better support the air claw device 32.

[0046] In this embodiment, the pressing unit 4 includes: a cylinder device 41 fixedly connected to the base plate 1 and a pressing block 42 fixedly connected to the cylinder device 41 .

[0047] When the switch outside the workstation is turned on, the sensing device senses the placement of the welding main part and will reflect it to the corresponding controller. The controller will send signals to the clamping unit 3, the pressing unit 4, the wiring harness bracket unit 5, the stabilizer bar bracket unit 6 and the hose bracket unit 7 to start each of them.

[0048] In this embodiment, the clamping unit 3 includes: a supporting device 31 fixedly connected to the base plate 1, and an air gripper device 32 fixedly connected to the supporting device 31. The air gripper device 32 is provided with two mutually symmetrical positioning protrusions 321, and is also provided with a second limiting device 33, which is fixedly connected to the air gripper device 32, and has a through hole on its upper portion.

[0049] When the welding main part is supported, start the switch outside the workstation, and after powering on the entire device, the corresponding sensing device on the clamping unit 3 can sense the insertion of the welding main part. At this time, the air claw device 32 will receive a clamping signal to clamp one end of the welding main part supported by the first support plate 21 and the third support plate 23. The two positioning protrusions 321 on the air claw device 32 are inserted into the corresponding holes on the welding main part. At the same time, the initial positioning pin is inserted into the welding main part through the through hole on the second limit device 33 to achieve a better fixing effect.

[0050] When the clamping unit 4 receives the signal, the cylinder device 41 drives the clamping block 42 to move downward until the clamping block 42 is in close contact with the welding main part, thereby pressing the welding main part.

[0051] In this embodiment, when the wire harness bracket unit 5, the stabilizer bar bracket unit 6 and the hose bracket unit 7 receive the signal, they will be started respectively, so that the wire harness bracket, the stabilizer bar bracket and the hose bracket are tightly fitted on the welding main part.

[0052] In this embodiment, a pushing device 51 which can slide relative to the harness bracket unit 5 is disposed on the upper portion of the harness bracket unit 5 .

[0053] When the wire harness support unit 5 receives the start signal, the pushing device 51 will push the placed wire harness support toward the welding main part to prepare for the next step of welding.

[0054] When the above steps are completed, the weldment is clamped, and the robot in the workstation welds the parts to be welded according to the system. After welding is completed, the weldment is taken out and the welding work is completed.

[0055] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0056] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0057] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0058] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
