Description

Technical Field

[0001] The utility model relates to the technical field of automobile production, in particular to a welding tooling for a bumper beam. Background Technique

[0002] A bumper beam is a device used to reduce injuries by absorbing collision energy when a vehicle is impacted. It consists of a main beam, an energy-absorbing box, and a mounting plate connecting to the vehicle. Both the main beam and the energy-absorbing box can effectively absorb collision energy during a low-speed collision of the vehicle, minimizing the damage to the vehicle's longitudinal beam caused by the impact force as much as possible, thereby playing its protective role for the vehicle. During production, operators need to weld and fix the energy-absorbing box to the main beam by welding. However, when welding the existing front bumper beam assembly of an automobile, it is inconvenient to effectively position the main beam and the energy-absorbing box, resulting in an easy deviation of the welding position and a reduction in welding quality. Moreover, it is inconvenient to firmly fix the two energy-absorbing boxes at the welding position of the bumper beam, causing the welding to shake easily and reducing the welding precision. Therefore, a welding tooling for a bumper beam is proposed to solve the above problems. Content of the Utility Model

[0003] In view of the above situation, in order to make up for the deficiencies of the prior art, the purpose of the utility model is to provide a welding tooling for a bumper beam, which effectively solves the problem of inconvenient fixation during the welding of the bumper beam.

[0004] The technical solution it adopts is that the utility model includes a support plate. At the front end of the support plate, there is a support beam block. The middle part of the support beam block is an arc with the opening facing upwards. At the left and right ends of the support beam block, there are respectively pressure blocks. At the front end of the support plate, there is a movable rod located above the support beam block and capable of moving up and down. At the lower end of the movable rod, there is an arc-shaped pressing beam block. At the left and right sides of the front end of the support plate, there are respectively sliding-connected pressure box blocks. The inner ends of the pressure box blocks are hinged to the movable rod through swing rods, and the two swing rods can form a figure-eight shape.

[0005] Compared with the prior art, the beneficial effect of the utility model is that it can realize the fixation and limitation of the main beam and the energy-absorbing box, ensure that the positions of the main beam and the energy-absorbing box remain relatively stationary during the welding process, facilitate the welding operation for welders, is simple and time-saving in operation, and only needs to start the electric push rod to realize the synchronous fixation and limitation of the main beam and the energy-absorbing box, and at the same time, the fixation and limitation can be released synchronously.

In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model. Therefore, the utility model is not limited to the basic implementation disclosed below.

[0013] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0014] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0015] Depend on Figures 1 to 4 It is given, including a support plate 1, a support beam block 2 is provided at the front end of the support plate 1, the middle part of the support beam block 2 is an arc with the arc mouth facing upward, and a pressure block 3 is provided at the left and right ends of the support beam block 2 respectively, and a moving rod 4 is provided at the front end of the support plate 1, which is located above the support beam block 2 and can move up and down, and an arc-shaped pressure beam block 5 is provided at the lower end of the moving rod 4. The left and right sides of the front end of the support plate 1 are respectively slidably connected with a pressure box block 6, and the inner end of the pressure box block 6 is hingedly connected to the moving rod 4 via a rocker rod 7, and the two rocker rods 7 can form an eight-shaped shape.

[0016] In order to facilitate supporting the support plate 1 , a bottom plate 8 is provided at the lower end of the support plate 1 .

[0017] In order to enable the moving rod 4 to move up and down, the moving rod 4 is slidably connected to the support plate 1. The front end of the support plate 1 is provided with an electric push rod 9 located above the moving rod 4. The free end of the electric push rod 9 is fixedly connected to the upper end of the moving rod 4.

[0018] To facilitate the movement of the two pressing box blocks 6, a chute 10 penetrating left and right is provided at the front end of the support plate 1, and a slider 11 located in the chute 10 is provided at the rear end of the pressing box block 6.

[0019] To facilitate enhancing the clamping effect, a plurality of anti-slip strips are respectively provided at the opposite ends of the two pressing box blocks 6.

[0020] To facilitate welding, a relief groove 12 is provided on the pressing block 3.

[0021] When the present utility model is in use, first place the main beam of the anti-collision beam on the supporting beam block 2, then place the two energy-absorbing boxes on both sides of the upper end of the supporting beam block 2 and make them contact with the pressing block 3. Then, when welding is required, turn on the electric push rod 9. The electric push rod 9 drives the moving rod 4 to move downward. The moving rod 4 drives the pressing beam block 5 to move downward for a certain distance and then contact and press the main beam downward, realizing the pressing and fixing of the main beam. While the moving rod 4 drives the pressing beam block 5 to move downward, it also drives the two pressing box blocks 6 to move away from each other through the swing rod 7, that is, the left pressing box block 6 moves to the left and the right pressing box block 6 moves to the right. After the two pressing box blocks 6 move away from each other for a certain distance, they respectively contact and clamp and fix the energy-absorbing box on their corresponding sides. Since the outer end of the energy-absorbing box is fixed by the pressing block 3 at this time, the clamping and fixing of the energy-absorbing box are realized. At this time, the positions of both the main beam and the energy-absorbing box are fixed and limited, so the position of the main beam relative to the position of the energy-absorbing box is fixed and limited.

[0022] At this time, welding can be carried out. During the welding process, the positions of the main beam and the energy-absorbing box do not move, thus ensuring the accuracy of welding. The relief groove 12 can facilitate the welding operation of the operator. When the welding is completed, turn on the electric push rod 9 to move in the reverse direction. The electric push rod 9 drives the moving rod 4 to move upward, and then drives the pressing beam block 5 to move upward. At the same time, it drives the two pressing box blocks 6 to move towards the middle through the swing rod 7. After the pressing beam block 5 moves upward for a certain distance, it disengages from the main beam, releasing the fixing and limiting of the main beam. At the same time, after the two pressing box blocks 6 move towards the middle for a certain distance, they disengage from the two energy-absorbing boxes, releasing the extrusion and fixing and limiting of the energy-absorbing boxes. At this time, the welded anti-collision beam can be removed from the supporting beam block 2.

[0023] Compared with the prior art, the beneficial effects of the present utility model are as follows: The provided supporting beam block, pressing beam block, pressing block, etc. can realize the fixing and limiting of the main beam and the energy-absorbing box, ensure that the positions of the main beam and the energy-absorbing box remain relatively stationary during the welding process, facilitate the welding operation of the welding personnel, are simple to operate, time-saving and labor-saving. Only by starting the electric push rod can the synchronous fixing and limiting of the main beam and the energy-absorbing box be realized, and at the same time, the fixing and limiting can be released synchronously. This structure is simple, novel in concept, easy to use and has strong practicability.

[0024] It should be noted that according to the needs of implementation, each component described in the embodiments of the present utility model can be split into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of the present utility model.

[0025] The above embodiments only express several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
