DETAILED DESCRIPTION

In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

Please refer to Figures 1-4. A technical solution provided by an embodiment of the utility model is as follows: the reversible welding tool includes a base 1, a bracket 2 is provided on the base 1, a slide groove 5 is vertically opened in the bracket 2, a slider 4 is slidably connected in the slide groove 5, a gear 8 is rotatably connected to the side of the slider 4 away from the slide groove 5, and a clamping member 9 for clamping a workpiece is fixedly connected to the end of the gear 8 away from the slide groove 5, a rack 7 meshing with the gear 8 is provided on the bracket 2, and during the vertical sliding of the slider 4, the gear 8 has an engagement stroke with the rack 7, and a driving component for driving the slider 4 to slide is provided on the bracket 2.

As a preferred technical solution, the driving assembly includes a motor 6 and a screw 3. The screw 3 is rotatably connected in the slide groove 5. A threaded hole is opened in the slider 4. The slider 4 is screwed to the screw 3 through the threaded hole. The motor 6 is fixedly connected to the top of the bracket 2. The output end of the motor 6 is coaxially fixedly connected to one end of the screw 3. Specifically, start the motor 6 to drive the screw 3 to rotate. The size of the slide groove 5 is adapted to the slider 4. The slide groove 5 limits the circumferential rotation of the slider 4, so that the slider 4 slides along the length direction of the slide groove 5. The clamp 9 is driven to slide vertically through the gear 8 to increase the welding height.

As a preferred technical solution, a clamping groove 14 is provided in the clamping member 9, a clamping plate 11 is slidably connected in the clamping groove 14, an electric push rod 10 is fixedly connected to the clamping member 9, and the output end of the electric push rod 10 is fixedly connected to the top of the clamping plate 11. Specifically, the electric push rod 10 is started, and the electric push rod 10 pushes the clamping plate 11, so that the clamping plate 11 clamps the workpiece to be processed and fixes the workpiece to be processed in the clamping groove 14.

As a preferred technical solution, a plurality of anti-skid protrusions 15 are fixedly connected to the bottom of the clamping plate 11 at equal distances. Specifically, each anti-skid protrusion 15 is made of rubber, which can increase the clamping force of the clamping plate 11 on the workpiece to be processed and prevent the workpiece from falling off from the clamping member 9.

As a preferred technical solution, a storage box 12 is provided on the base 1, and a storage slot is opened in the storage box 12. A plurality of partitions 13 are equidistantly snap-fitted in the storage slot, and storage intervals are formed between two adjacent partitions 13 and between the side wall of the storage slot and the adjacent partitions 13. Specifically, a plurality of slots are equidistantly opened in the storage slot, and each partition 13 can be snap-fitted in any slot. The number of partitions 13 can be freely installed, and the size of the interval space can be freely adjusted. Welding tools can also be placed to fix them, making it convenient to take the welding tools.

Working principle: The reversible welding tool first clamps the workpiece to be processed in the clamping groove 14 in the clamping part 9 through the cooperation between the electric push rod 10 and the clamping plate 11. When the workpiece to be processed needs to be flipped at a large angle and the width is large, the motor 6 is started to drive the screw 3 to rotate, so that the slider 4 slides along the length direction of the slide groove 5. The slider 4 first drives the clamping part 9 to move upward through the gear 8 to raise the welding height. While the slider 4 moves vertically upward, the gear 8 drives the clamping part 9 to flip through the meshing transmission of the rack 7, which can realize the flipping of the workpiece to be processed and avoid collision with the base 1 during the flipping process.

The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
