Description

Technical Field

[0001] The utility model belongs to the technical field of welding fixtures, and in particular relates to a fixture for welding an automobile anti-collision beam. Background Art

[0002] During the automotive production process, the welding quality of automotive anti-collision beams is crucial to the passive safety performance of the vehicle. As automotive designs diversify, the shapes of anti-collision beams are becoming increasingly complex. For example, curved anti-collision beams are becoming more and more widely used.

[0003] Traditional automotive anti-collision beam welding fixtures have obvious defects when facing complex shapes such as arc-shaped anti-collision beams. These traditional fixtures can usually only fix the anti-collision beam in a specific position. When welding the anti-collision beam, it is difficult for welders to perform convenient, efficient and high-quality welding on different sides of the anti-collision beam. Especially for the arc-shaped anti-collision beam body, when it is necessary to weld its inside and outside, the welding operation becomes extremely difficult due to the lack of flexible adjustment function of traditional fixtures. This not only leads to low welding efficiency, but also easily leads to unstable welding quality, such as uneven welding, insufficient welding strength and other problems, which in turn affect the overall performance of the anti-collision beam. Therefore, a fixture for welding automotive anti-collision beams is needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a clamp for welding an automobile anti-collision beam, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fixture for welding automobile anti-collision beams, comprising a machine block, a displacement groove being provided on the machine block, two threaded rods being rotatably provided inside the displacement groove, the adjacent ends of the two threaded rods being fixedly connected, the thread directions of the two threaded rods being opposite, the outer sides of the two threaded rods being threadedly connected with displacement blocks, the two displacement blocks being slidably provided in the displacement grooves, vertical blocks being fixedly provided on the two displacement blocks, transposition turntables being rotatably provided on the adjacent sides of the two vertical blocks, clamping blocks being fixedly provided on the adjacent sides of the two transposition turntables, the anti-collision beam body being clamped on the adjacent sides of the two clamping blocks, each of the clamping blocks being located at the eccentric position of the corresponding transposition turntable, and a multi-stage positioning telescopic rod being fixedly provided on the adjacent sides of the two transposition turntables.

[0006] By setting a transposition turntable, two threaded rods with opposite thread directions are set in the displacement groove on the machine block. By rotating the threaded rods, the two displacement blocks can move towards or in opposite directions to achieve adaptation to anti-collision beams of different sizes. The transposition turntable on the vertical block can be rotated, and the clamping block is located at the eccentric position of the transposition turntable. After the clamping block clamps the anti-collision beam, the angle of the anti-collision beam can be easily changed by rotating the transposition turntable, which is convenient for welding the inside and outside of the arc-shaped anti-collision beam. The multi-stage positioning telescopic rod can ensure the stability and positioning accuracy of the two transposition turntables during the rotation process. When the disk drive rotates, the multi-stage positioning telescopic rod can ensure that they rotate in a synchronized manner, ensuring the relative position accuracy of the two transposition turntables during the rotation process, and avoiding the problem of anti-collision beam offset due to asynchronous rotation. At the same time, when the transposition turntables move closer to or away from each other, the multi-stage positioning telescopic rod can adaptively extend and retract, ensuring that the clamp can always stably fix and operate the anti-collision beam during the entire welding operation, effectively improving the quality and efficiency of welding, thereby ensuring the accuracy of the welding position and greatly improving the welding efficiency and quality.

[0007] As a preferred embodiment, a first drive motor is provided at the rotation point of one end of the threaded rod on one side, and the first drive motor is fixedly provided on one side of the machine block through a first fixing block.

[0008] As a preferred embodiment, a second drive motor is provided at the rotation portion of one side of the transposition turntable, and the second drive motor is fixedly provided on one side of the vertical block via a second fixing block.

[0009] As a preferred embodiment, two limiting holes are provided on each of the two clamping blocks.

[0010] As a preferred embodiment, two limiting rods are fixedly provided on each of the two clamping blocks.

[0011] As a preferred embodiment, the limiting rods on the two clamping blocks are inserted into the limiting holes on each other.

[0012] By setting a limit rod, when the two clamping blocks clamp and move the anti-collision beam, the limit rods will be inserted into each other's limit holes. This design can make the anti-collision beam firmly limited by the limit rods inserted up and down. On the one hand, during the clamping and moving process, it can effectively prevent the anti-collision beam from shifting or shaking in the horizontal direction, ensuring the position stability of the anti-collision beam in the clamp, and thus ensuring the accuracy of the welding position. On the other hand, this limiting method can also share the clamping force of the clamping block on the anti-collision beam to a certain extent, avoiding the problem of local deformation of the anti-collision beam caused by excessive concentration of clamping force in certain parts, helping to improve welding quality and efficiency, and reducing welding defects caused by changes in the position of the anti-collision beam.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The utility model provides a transposition turntable, and two threaded rods with opposite thread directions are provided in the displacement groove on the machine block. By rotating the threaded rods, the two displacement blocks can move toward or in opposite directions to achieve the adaptation of anti-collision beams of different sizes. The transposition turntable on the vertical block can be rotated, and the clamping block is located at the eccentric position of the transposition turntable. When the clamping block clamps the anti-collision beam, the angle of the anti-collision beam can be easily changed by rotating the transposition turntable, which is convenient for welding the inside and outside of the arc-shaped anti-collision beam. The multi-stage positioning telescopic rod can ensure the stability and positioning accuracy of the two transposition turntables during the rotation process. When the transposition turntable is driven to rotate, the multi-stage positioning telescopic rod can ensure that they rotate in a synchronous positioning manner, ensuring the relative position accuracy of the two transposition turntables during the rotation process, and avoiding the problem of anti-collision beam offset due to asynchronous rotation. At the same time, when the transposition turntables move closer to or away from each other, the multi-stage positioning telescopic rod can adaptively extend and retract, ensuring that the clamp can always stably fix and operate the anti-collision beam during the entire welding operation, effectively improving the quality and efficiency of welding, thereby ensuring the accuracy of the welding position and greatly improving the welding efficiency and quality.

[0015] The utility model provides a limit rod, and when the two clamping blocks clamp and move the anti-collision beam, the limit rods will be inserted into the limit holes on each other. This design can make the anti-collision beam firmly limited by the limit rods inserted up and down. On the one hand, during the clamping and moving process, it can effectively prevent the anti-collision beam from shifting or shaking in the horizontal direction, ensuring the position stability of the anti-collision beam in the clamp, and thus ensuring the accuracy of the welding position. On the other hand, this limiting method can also share the clamping force of the clamping block on the anti-collision beam to a certain extent, avoiding the problem of local deformation of the anti-collision beam caused by excessive concentration of clamping force in certain parts, helping to improve welding quality and efficiency, and reducing welding defects caused by changes in the position of the anti-collision beam.

[0026] By setting a transposition turntable 6, two threaded rods 3 with opposite thread directions are set in the displacement groove 2 on the machine block 1. By rotating the threaded rod 3, the two displacement blocks 4 can be moved toward or in the opposite direction to achieve adaptation to anti-collision beams 8 of different sizes. The transposition turntable 6 on the vertical block 5 is rotatable, and the clamping block 7 is located at the eccentric position of the transposition turntable 6. After the clamping block 7 clamps the anti-collision beam 8, the angle of the anti-collision beam 8 can be easily changed by rotating the transposition turntable 6, which is convenient for welding the inside and outside of the arc-shaped anti-collision beam 8. The multi-stage positioning telescopic rod 9 can ensure the stability and positioning accuracy of the two transposition turntables 6 during the rotation process. When the two transposition turntables 6 are driven to rotate, the multi-stage positioning telescopic rod 9 can ensure that they rotate in a positioned and synchronous manner, thereby ensuring the relative position accuracy of the two transposition turntables 6 during the rotation process, and avoiding the problem of the anti-collision beam 8 being offset due to asynchronous rotation. At the same time, when the transposition turntables 6 move closer to or away from each other, the multi-stage positioning telescopic rod 9 can be adaptively extended and retracted, ensuring that during the entire welding operation, the clamp can always stably fix and operate the anti-collision beam 8, effectively improving the quality and efficiency of welding, thereby ensuring the accuracy of the welding position and greatly improving the welding efficiency and welding quality.

By setting the limiting rods 15, when the two clamping blocks 7 clamp and move the anti-collision beam 8, the limiting rods 15 will be inserted into the limiting holes 14 on each other. This design can make the anti-collision beam 8 be firmly limited by the limiting rods 15 inserted up and down. On the one hand, during the clamping and moving process, it can effectively prevent the anti-collision beam 8 from offsetting or shaking in the horizontal direction, ensuring the position stability of the anti-collision beam 8 in the clamp, and thus ensuring the accuracy of the welding position. On the other hand, this limiting method can also share the clamping force of the clamping block 7 on the anti-collision beam 8 to a certain extent, avoiding the problem of local deformation of the anti-collision beam 8 caused by excessive concentration of clamping force in certain parts, which helps to improve welding quality and efficiency and reduce welding defects caused by changes in the position of the anti-collision beam 8.
