Description

Technical Field

[0001] This utility model relates to the field of welding positioning fixture technology, specifically a positioning fixture for a welding workstation. Background Technology

[0002] Welding positioning fixtures are special clamps used in the welding process. Their main function is to accurately position and fix the workpiece to be welded, ensuring stability and consistency during the welding process, thereby improving welding quality and efficiency.

[0003] When performing welding alignment and positioning, one workpiece is usually fixed, and then the welding surface of another workpiece is aligned with the welding surface of the fixed workpiece before the second workpiece is fixed. However, in actual operation, after the welding points are aligned, the welded parts are fixed. During the fixing process, there may be shaking deviations or misfitting of the fixing parts, which will eventually cause a certain deviation in the originally aligned welding surfaces. At this time, repositioning is required. The overall operation is relatively troublesome and the alignment is relatively difficult. Utility Model Content

[0004] The purpose of this invention is to provide a positioning fixture for a welding workstation to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: it includes a welding table and a positioning carrier plate. A pair of positioning carrier plates are slidably connected to the welding table. A pair of clamping plates are slidably connected to the upper end of each positioning carrier plate. A rotating column is rotatably connected to the clamping plate. An end plate is fixed on the rotating column. A locking bolt is installed at one end of the end plate that is close to each other. A driving component for driving the positioning carrier plates to slide is provided inside the welding table. A synchronization component is provided inside the positioning carrier plate and at a position corresponding to the clamping plate.

[0006] Preferably, the driving assembly includes a driving groove, which is formed on the upper end of the welding platform. A pair of driving blocks are slidably connected in the driving groove. The upper end of the driving blocks is fixed to the positioning carrier plate. A bidirectional lead screw is rotatably connected in the driving groove. The bidirectional lead screw passes through the driving blocks and is threadedly connected to the driving blocks.

[0007] Preferably, a worm gear is rotatably connected at the middle position of the drive groove and below the bidirectional lead screw, a worm wheel that meshes with the worm gear is fixed at the middle position of the bidirectional lead screw, and a rocker arm is fixedly connected to the end of the worm gear extending out of the welding table.

[0008] Preferably, the synchronization component includes a synchronization groove and a synchronization slider. The synchronization groove is formed on the upper end of the positioning carrier plate and is aligned with the clamping plate. A pair of synchronization sliders are slidably connected in the synchronization groove. A transmission rack is fixed on one side of the synchronization sliders that are close to each other. A synchronization gear is rotatably connected in the middle of the synchronization groove. The synchronization gear meshes with the transmission rack. The upper end of the synchronization slider is fixed to the bottom of the clamping plate.

[0009] Preferably, a telescopic cylinder is fixed to the outside of the positioning carrier plate, and the output end of the telescopic cylinder is located in the drive groove and is fixedly connected to one of the synchronous sliders.

[0010] Preferably, anti-slip strips are fixed at equal intervals on the upper end of the positioning carrier plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: before welding alignment, the two workpieces to be welded are fixed on the positioning plate respectively. By using the synchronous sliding of the positioning plate, the welding surfaces of the workpieces can be joined, ensuring welding stability. At the same time, it avoids the troublesome operation of re-aligning and fixing the workpieces due to workpiece deviation during the fixing process. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: including a welding table 1 and a positioning carrier plate 2. A pair of positioning carrier plates 2 are slidably connected on the welding table 1. A pair of clamping plates 3 are slidably connected to the upper end of each positioning carrier plate 2. A rotating column 31 is rotatably connected to the clamping plate 3. An end plate 4 is fixed on the rotating column 31. A locking bolt 41 is installed at one end of the end plate 4 that is close to each other. A driving component for driving the positioning carrier plates 2 to slide is provided in the welding table 1. A synchronization component is provided in the positioning carrier plate 2 and at a position corresponding to the clamping plate 3. Anti-slip strips 21 are fixed at equal intervals on the upper end of the positioning carrier plate 2.

[0019] The drive assembly includes a drive groove 11, which is located on the upper end of the welding table 1. A pair of drive blocks 12 are slidably connected in the drive groove 11. The upper ends of the drive blocks 12 are fixed to the positioning carrier plate 2. A bidirectional lead screw 13 is rotatably connected in the drive groove 11. The bidirectional lead screw 13 passes through the drive blocks 12 and is threadedly connected to the drive blocks 12. A worm gear 15 is rotatably connected in the middle of the drive groove 11 and below the bidirectional lead screw 13. A worm wheel 14 that meshes with the worm gear 14 is fixed in the middle of the bidirectional lead screw 13. The end of the worm gear 15 extends out of the welding table 1 and is fixedly connected to a rocker arm 16.

[0020] The synchronization component includes a synchronization groove 5 and a synchronization slider 51. The synchronization groove 5 is located on the upper end of the positioning carrier plate 2 and is aligned with the clamping plate 3. A pair of synchronization sliders 51 are slidably connected in the synchronization groove 5. A transmission rack 52 is fixed on the side of the synchronization sliders 51 that are close to each other. A synchronization gear 53 is rotatably connected in the middle of the synchronization groove 5. The synchronization gear 53 meshes with the transmission rack 52. The upper end of the synchronization slider 51 is fixed to the bottom of the clamping plate 3. A telescopic cylinder 54 is fixed on the outside of the positioning carrier plate 2. The output end of the telescopic cylinder 54 is located in the drive groove 11 and is fixedly connected to one of the synchronization sliders 51.

[0021] Working principle: First, connect the entire device to an external power source. Then, fix the two welding parts onto different positioning plates 2, ensuring their welding surfaces protrude. The positioning plates 2 then slide synchronously towards each other, bringing the welding surfaces of the workpieces together for accurate positioning. This ensures stable welding and, by fixing first and then aligning, guarantees that the welding surfaces of the workpieces can be aligned at once. Throughout the process, the telescopic cylinder 54 drives the synchronous slider 51 to slide. The transmission rack 52 and synchronous gear 53 ensure the synchronous sliding of the synchronous slider 51, ultimately clamping both sides of the workpiece. Furthermore, when welding sheet metal, this method can also be used... The rotation of the locking bolt 41 presses down on the top of the plate structure, increasing its stability. At the same time, the rotation of the rotating column 31 can drive the end plate 4 to rotate, causing it to deviate from the top of the workpiece. After welding, the material can be unloaded more easily without being blocked by the end plate 4. Furthermore, the rotation of the rocker arm 16 can drive the worm gear 15 to rotate, and the transmission of the worm wheel 14 can drive the bidirectional lead screw 13 to rotate, so that the drive block 12 and the positioning carrier plate 2 slide synchronously. As the positioning carrier plate 2 moves closer, the welding surface of the workpiece can be aligned closer and closer. The synchronous sliding clamping of the clamping plate 3 can ensure that the workpiece is fixed in the middle position of the positioning carrier plate 2, thereby achieving accurate alignment of the welding surface of the workpiece.
