Through the cooperation of the limit bar 14, the limit groove and the rotating sleeve, the base 2 on the side of the limit bar 14 can slide with the threaded rod 6 while ensuring the stable rotation of the threaded rod 6. The base 2 on the side of the nut 36 close to the guide rod 15 is threadedly connected to the guide rod 15 through the nut 36, which can not only fix the base 2, but also adjust the position of the base 2 on the guide rod 15, thereby realizing the position adjustment of the base 2, and can weld brackets 1 of different widths. At the same time, the two bases 2 can be separated, which is convenient for welding the next bracket 1.

[0022] The welding assembly includes a swing groove 10, a welding gun 17, a welding gun cover 22, and a swing groove 10 is provided near the bottom of the slide plate 12. The swing groove 10 is in a "Z" shape. The welding gun 17 is slidably connected in the swing groove 10. One end of the welding gun 17 is aligned with the connection between the bracket 1 and the cabinet panel 7, and an adjustment mechanism and a driving mechanism are provided on the welding gun 17. Since the welding gun 17 is slidably connected in the swing groove 10, with the cooperation of the adjustment mechanism and the driving mechanism, the welding gun 17 can achieve a continuous "Z"-shaped swing with the same amplitude when welding the connection between the bracket 1 and the cabinet panel 7, thereby improving the quality of the welding of the prop display counter bracket and avoiding the situation that the swing amplitude cannot be consistent throughout the whole process when the welding gun 17 is manually used for welding, resulting in reduced welding quality.

[0023] The adjustment mechanism includes a clamping ring 20, an inclined rod 27, and a sleeve 19. The two clamping rings 20 are arranged on both sides of the outer wall of the welding gun 17. The clamping rings 20 can clamp and fix the welding gun 17 to maintain the posture of the welding gun 17. The end of the clamping ring 20 away from the welding gun 17 is fixedly connected to a push rod 30. The inner part of the sleeve 19 is sleeved with a collar 29. The sleeve 19 and the collar 29 are movably installed by bolt 23, the other end of the push rod 30 is slidably installed in the collar 29, and a spring 28 is fixed between the push rod 30 and the collar 29. The spring 28 and the push rod 30 are used to cooperate with the left and right swing of the welding gun 17 when it slides in the swing groove 10. Since the collar 29 is sleeved inside the sleeve 19, when it is necessary to change the welding posture of the welding gun 17, the bolt 232 can be loosened, the collar 29 can be rotated, the welding posture of the welding gun 17 can be adjusted, and finally the fixing bolt 232 can be tightened. The end of the sleeve 19 away from the collar 29 is fixedly connected to the bracket 18, the inclined rod 27 is fixedly connected to the upper end of the bracket 18, and the other end of the inclined rod 27 passes through the support plate 11 and is slidably connected to the support plate 11. The sliding connection between the inclined rod 27 and the support plate 11 is to cooperate with the up and down swing of the welding gun 17 when it slides in the swing groove 10.

[0024] The driving mechanism includes a card box 21, a cylinder 23, a gear three 26 and a welding gun sleeve 22. The welding gun sleeve 22 is sleeved on the outer wall of the welding gun 17. A card slot 33 is provided inside the card box 21. The welding gun sleeve 22 slides and engages in the card slot 33. One end of the card box 21 away from the welding gun sleeve 22 is fixedly connected to the output end of the cylinder 23. The end of the cylinder 23 away from the card box 21 is fixedly connected to a connecting block 24. The cooperation between the card slot 33 and the welding gun sleeve 22 can limit the axial direction of the welding gun 17. At the same time, the cylinder 23 can separate from or engage with the welding gun 17 when driving the card box 21 to move. A rack is provided on the upper part of the connecting block 24. A connecting plate four 58 is fixedly connected to the lower part of the support plate 11. One side of the connecting plate four 58 is rotatably connected to the gear three 26, and the other side is fixedly connected to the electric Machine 2, the output shaft of motor 2 is fixedly connected with gear 3 26, gear 3 26 is meshed with the rack on the connecting block 24, and gear 3 26 is a half gear, the upper end of the connecting block 24 is slidably connected with the support plate 11, and when motor 2 is started, gear 3 26 can be driven to rotate. Since gear 3 26 is meshed with the rack on the connecting block 24, the connecting block 24 can be driven to move, the connecting block 24 drives the cylinder 23 to move, the cylinder 23 drives the card box 21 to move, and the card box 21 drives the welding gun 17 to move. The welding gun 17 slides along the swing groove 10 under the support and fixation of the clamp ring 20, so that the "Z"-shaped swing of the welding gun 17 with a consistent amplitude throughout the entire range can be achieved, thereby significantly improving the welding quality of the prop display counter bracket.

[0025] The welding assembly also includes a lubrication mechanism, which includes an oil tank 25, an oil channel 35 and a pulley 38. The oil tank 25 is installed on the support plate 11, and a communicating oil channel 35 is provided inside the support plate 11 and the slide plate 12. One end of the oil channel 35 is communicated with the oil tank 25, and the other end is communicated with the swing groove 10. The lubricating oil in the oil tank 25 is introduced into the swing groove 10 through the oil channel 35, and moves along the inner wall of the swing groove 10, thereby improving the smoothness of the welding gun 17 when sliding in the swing groove 10, avoiding the sliding jam, thereby affecting the swing of the welding gun 17, and causing the forming quality of the weld to decrease. A retaining groove 57 is also provided inside the support plate 11, one end of which is connected to the oil passage 35, and a stopper 40 is slidably connected inside the retaining groove 57, and a fixed block 39 is fixedly connected thereto. A spring four 56 is fixedly connected between the fixed block 39 and the stopper 40, and the stopper 40 can control the opening and closing of the oil passage 35. The pulley 38 is rotatably mounted inside the retaining groove 57 and is arranged on the right side of the fixed block 39. An inclined slide groove 55 is also provided below the retaining groove 57 on the support plate 11, and the upper end of the connecting block 24 is slidably arranged inside the slide groove 55, a spring two 37 is fixedly connected between the connecting block 24 and the slide groove 55, and a connecting line 31 is fixedly connected between the connecting block 24 and the stopper 40, and the connecting line 31 is fitted and connected to the pulley 38. When the connecting block 24 moves up and down, the stopper 40 is driven by the connecting line 31 to intermittently block the oil passage 35 under the cooperation of the pulley 38 and the spring four 56, thereby reducing the use of lubricating oil while ensuring the lubrication effect, and saving more lubricating oil.

[0026] A sponge groove 60 is further provided inside the slide plate 12 at the connection point between the oil passage 35 and the swing groove 10. A sponge pad 50 is installed inside the sponge groove 60. The sponge pad 50 is arranged in a triangular shape. The sponge pad 50 is arranged to prevent the lubricating oil from flowing directly from the oil passage 35 to the swing groove 10, thereby expanding the range of lubrication flowing from the oil passage 35 to the swing groove 10, so that the lubricating oil can be more evenly applied to the inner wall of the swing groove 10, thereby improving the smoothness of the sliding of the welding gun 17. The triangular sponge pad 50 is to allow the lubricating oil to fill the sponge pad 50 horizontally before flowing to the inner wall of the swing groove 10, thereby preventing the sponge pad 50 in the middle position from being filled first and then flowing directly to the inner wall of the swing groove 10, thereby further improving the uniformity of the distribution of the lubricating oil on the inner wall of the swing groove 10, thereby further improving the smoothness of the sliding of the welding gun 17 in the swing groove 10. The bottom end of the slide plate 12 is also fixedly connected to an oil collecting plate 59 , and the oil collecting plate 59 can collect the lubricating oil flowing out of the swing groove 10 .

[0027] The welding assembly also includes an oil-evening mechanism, which includes a gear 1 8, a gear 2 9, a swing rod 51, an air channel 1 34 and a tapered groove 47. The interior of the slide plate 12 is also provided with an air channel 1 34 and an air channel 2 41. One end of the air channel 1 34 is connected to the swing groove 10, and the other end is connected to the tapered groove 47 also provided inside the slide plate 12. The opening of the air channel 1 34 faces the right side wall of the upper half of the swing groove 10. One end of the air channel 2 41 is connected to the swing groove 10 and the opening is aligned with the air channel 1 34. The other end opening is connected to the middle of the swing groove 10 and is aligned with the left side wall of the middle of the swing groove 10. A connecting plate three 45 is fixedly connected inside the conical groove 47, and a rotating shaft 44 is rotatably connected to the connecting plate three 45. The end of the rotating shaft 44 located inside the conical groove 47 is fixedly connected to a fan blade 46, and the end located outside the conical groove 47 is fixedly connected to a gear four 61. The side wall of the slide plate 12 is fixedly connected to a connecting plate one 42 and a connecting plate two 43. Gear one 8 is rotatably connected to the connecting plate one 42 and meshed with the rack on the guide rod 15. Gear two 9 is rotatably connected to the connecting plate two 43. Gear four 61 is meshed with gear two 9. A belt 62 is rotatably fitted between gear one 8 and gear two 9.

[0028] In conjunction with the accompanying drawings, it can be seen that when the lubricating oil flows from the oil passage 35 to the inner wall of the swing groove 10, in the absence of external force, the lubricating oil on the upper inner wall of the right side of the swing groove 10 cannot completely flow downward along the upper inner wall of the right side of the swing groove 10 under the action of gravity, and the lubricating oil flowing to the middle inner wall of the left side of the swing groove 10 cannot flow downward along the middle inner wall of the left side of the swing groove 10 under the action of gravity, resulting in the lubricating oil not being evenly applied to the inner wall of the swing groove 10. Therefore, when the slide plate 12 moves, due to the meshing connection between the gear 1 8 and the rack on the guide rod 15, it will drive the gear 1 8 to rotate, the gear 1 8 will drive the gear 2 9 to rotate through the belt 62, the gear 2 9 will drive the gear 4 61 to rotate, the gear 4 61 will drive the fan blade 46 to rotate through the rotating shaft 44, and the diameter of the gear 2 9 is greater than the diameter of the gear 4 61, so it will The acceleration gear 4 61 rotates, and the fan blade 46 blows the airflow into the interior of the swing groove 10 when it rotates. Since the opening of the airway 1 34 faces the right side wall of the upper half of the swing groove 10, the airflow will blow the lubricating oil along the upper right inner wall of the swing groove 10 as much as possible. Since one end of the airway 2 41 is connected with the swing groove 10 and the opening is aligned with the airway 1 34, the airway 2 41 will also receive part of the airflow blown out from the airway 1 34, and the other end opening of the airway 2 41 is connected with the middle of the swing groove 10 and is aligned with the left side wall of the middle of the swing groove 10. Therefore, the airflow flowing into the airway 2 41 will also blow the lubricating oil downward on the inner wall of the left middle of the swing groove 10 as much as possible, thereby maximizing the uniformity of the distribution of the lubricating oil on the inner wall of the swing groove 10, and further improving the smoothness of the sliding of the welding gun 17 in the swing groove 10. A swing assembly is provided inside the connection between the airway 1 34 and the swing groove 10, and the swing assembly includes a swing rod 51, a ball 52, and a slide cylinder 53. The swing rod 51 is rotatably installed in the middle position of the airway 1 34, and two slide cylinders 53 are distributed on both sides of the swing rod 51 and fixedly connected to the airway 1 34. The slide cylinders 53 are slidably connected with the balls 52, and a spring 3 54 is fixedly connected between the balls 52 and the slide cylinders 53. The same swing assembly is also provided inside the connection between the airway 2 41 and the middle part of the swing groove 10. Components, roller grooves 48 are provided at the bending parts of the upper and middle parts of the left side wall of the swing groove 10 and the bending parts of the middle and lower parts of the right side wall of the swing groove 10. Each roller groove 48 is rotatably installed with multiple groups of rollers 49. The setting of the rollers 49 can reduce the friction of the welding gun 17 when passing through the bending parts of the upper and middle parts of the left side wall of the swing groove 10 and the bending parts of the middle and lower parts of the right side wall of the swing groove 10, thereby improving the smoothness of sliding, and the distance between adjacent rollers 49 is less than the diameter of the welding gun 17. When the airflow is blown out from air channel 1 34 and air channel 2 41 toward the swing groove 10, it will drive the swing rod 51 to rotate. When the swing rod 51 rotates and collides with the ball 52, it will rotate in the opposite direction under the action of spring three 54, thereby realizing the swing of the swing rod 51. When the swing rod 51 swings, it can continuously adjust the angle of the airflow blowing toward the inner wall of the swing groove 10, so that the lubricating oil flow on the inner wall of the swing groove 10 can be blown over a larger range, and the distribution uniformity of the lubricating oil on the inner wall of the swing groove 10 will also be improved, further improving the smoothness of the sliding of the welding gun 17 in the swing groove 10.

[0030] Working principle: First, the two bases 2 are pressed against the two sides of the cabinet plate 7, and then the nuts 36 on the guide rod 15 are tightened to fix the two bases 2. The two bases 2 limit the cabinet plate 7, and the two clamping blocks 5 limit the bracket 1. The clamping ring 20 clamps and fixes the welding gun 17. The cylinder 23 is started to drive the card box 21 to move. The cooperation of the card slot 33 and the welding gun sleeve 22 can limit the axial direction of the welding gun 17. When the motor 1 3 is started, the threaded rod 6 is driven to rotate through the cooperation of the worm gear 4 and the worm 16. When the threaded rod 6 rotates, it drives the slide plate 12 to move with the cooperation of the guide rod 15. At the same time, the motor 2 is started, and the gear 3 26 and the connecting block 24 are connected. With the cooperation of the rack, the connecting block 24 is driven to move up and down, and then the welding gun 17 is driven to move up and down. The welding gun 17 slides along the swing groove 10 under the support and fixation of the clamp ring 20, so that the welding gun 17 can achieve a "Z"-shaped swing with a consistent amplitude throughout the entire range, thereby significantly improving the welding quality of the prop display counter bracket. While the slide plate 12 moves, the lubricating oil in the oil tank 25 flows into the inner wall of the swing groove 10 through the oil channel 35, improving the smoothness of the welding gun 17 when sliding in the swing groove 10, avoiding sliding jams, thereby affecting the swing of the welding gun 17, causing the forming quality of the weld to decline, and significantly improving the welding quality of the prop display counter bracket.
