DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-6 The top of the slide 13 is provided with a block 14 which slides with the groove 7, and the block 14 is inserted into the groove 7 to push the slide 13 upwards.

[0026] The surface of the slide 13 and the surface of the inclined push block 12 are both slidably connected to the inner wall of the storage groove 9. The slide 13 moves upward under the guidance of the storage groove 9, and the inclined push block 12 moves horizontally under the guidance of the storage groove 9. The bottom end of the slide 13 is set as an inclined surface that slides with the inclined surface of the inclined push block 12, and the other end of the screw rod 11 is fixed with a knob, which facilitates the rotation of the screw rod 11.

[0027] A plate outlet groove 17 is provided at the top of the cross plate 2, and the inner wall of the plate outlet groove 17 is slidably connected to the surface of the block 14. The plate outlet groove 17 guides the movement of the block 14 and stores the block 14 when the support plate 4 is disassembled. An observation groove 18 is provided on the front of the cross plate 2. The interior of the observation groove 18 and the interior of the plate outlet groove 17 are both connected to the interior of the storage groove 9. The inner wall of the observation groove 18 is slidably connected to the surface of the slide seat 13. The position of the slide seat 13 and the position of the inclined push block 12 can be observed through the observation groove 18, so as to facilitate the adjustment of the screw 11.

[0028] The inner walls on both sides of the movable plate groove 3 are fixed with limit blocks 15 and guide strips 16. The surfaces of the two limit blocks 15 are slidably connected with the surface of the support plate 4. The support plate 4 slides into the movable plate groove 3, and the support plate 4 is finally supported by the limit blocks 15. At this time, the slot 7 is aligned with the block 14, and there is no need to manually align the slot 7 and the block 14, thereby improving the installation efficiency.

[0029] The surface of the support plate 4 is provided with two guide grooves 19 that slide with the guide bar 16. The surface of the support plate 4 is coated with Teflon coating, which is wear-resistant and impact-resistant. The bottom end of the support plate 4 is slidably connected to the top end of the cross plate 2. The support plate 4 is limited by the guide bar 16 through the guide groove 19, thereby improving the stability of the support plate 4 in the vertical direction.

[0030] The positioning assembly 5 includes a slide groove 51, a mounting groove 52 and two clamping assemblies 6. The slide groove 51 is opened on the front side of the base 1. The inner wall of the slide groove 51 is rotatably connected to a first bidirectional screw rod 53 through a sealed bearing. The surface of the first bidirectional screw rod 53 is threadedly connected to two sliders 54 through a screw nut. A transmission rod 55 is fixedly provided on the front side of the two sliders 54. A positioning seat 56 is fixedly provided at one end of the two transmission rods 55. The rotating first bidirectional screw rod 53 drives the two positioning seats 56 to move through the slider 54 and the transmission rod 55, prompting the two positioning seats 56 to move toward the direction of the two parts close to the top of the support plate 4.

[0031] The surfaces of the two sliders 54 are slidably connected to the inner wall of the slide groove 51, and the bottom ends of the two positioning seats 56 are slidably connected to the two sides of the top of the base 1 respectively. The mounting groove 52 is opened on the surface of the base 1, and a positioning motor 57 is fixedly provided on the inner wall of the mounting groove 52. The positioning motor 57 is a forward and reverse motor. The transmission shaft of the positioning motor 57 is fixedly connected to one end of the first bidirectional screw rod 53. When the positioning motor 57 is started, the positioning motor 57 drives the first bidirectional screw rod 53 to rotate. There is no need to manually rotate the first bidirectional screw rod 53, which is more labor-saving.

[0032] The two clamping assemblies 6 each include a vertical slot 61 and a clamping motor 62. The two vertical slots 61 are respectively opened on one side of the two positioning seats 56. The inner walls of the two vertical slots 61 are rotatably connected with a second bidirectional screw rod 63 through a sealed bearing. The surfaces of the two second bidirectional screw rods 63 are threadedly connected with two clamping blocks 64 that slide with the vertical slot 61 through screw nuts. The two clamping motors 62 are respectively fixedly arranged on the top ends of the two positioning seats 56. The two clamping motors 62 are both forward and reverse motors. The transmission shafts of the two clamping motors 62 are respectively fixedly connected to one end of the two second bidirectional screw rods 63. When the clamping motor 62 is started, the clamping motor 62 will drive the second bidirectional screw rod 63 to rotate, and the second bidirectional screw rod 63 will drive the two clamping blocks 64 to move. The two clamping blocks 64 clamp the tops of the suspended parts or the parts supported by the support plate 4, thereby preventing the two parts to be welded from shaking during welding.

[0033] When in use, the welding slag produced during the welding process falls to the top of the support plate 4. After removing the welding part, the knob is turned, and the knob drives the screw rod 11 to rotate. The screw rod 11 pulls the oblique push block 12 to move horizontally, and the slide seat 13 and the block 14 will lose the support of the oblique push block 12 and move downward, so that the block 14 is separated from the slot 7. Then, both hands are put into the auxiliary pull slot 8, the old support plate 4 is pulled out, and the new support plate 4 is slid in along the inner wall of the movable plate slot 3. The knob is turned in the opposite direction, and the screw rod 11 pushes the oblique push block 12 to move in the opposite direction. The oblique push block 12 will push the slide seat 13 and the block 14 upward through the inclined surface, prompting the block 14 to be stuck in the slot 7, and the replacement of the support plate 4 is completed, which is very convenient.

[0034] It should be added that the support plate 4 is slid into the movable plate groove 3 and is finally stopped by the limit block 15. At this time, the slot 7 is aligned with the block 14, and there is no need to manually align the slot 7 and the block 14, which improves the installation efficiency. The support plate 4 is limited by the guide bar 16 through the guide groove 19, which improves the stability of the support plate 4 in the vertical direction. The support plate 4 with welding slag attached to the surface can be manually knocked off after being removed, which is less likely to damage the positioning motor 57 than the cleaning method of directly knocking on the base 1. The support plate 4 with the welding slag knocked off can be recycled, reducing the cost of use.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
