Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and in particular to a welding device for the partition of a charging pile box. Background Technology

[0002] The charging pile enclosure protects the components inside. Multiple partitions are installed in different locations within the enclosure, dividing the internal space and allowing the components to be categorized, layered, and fixed in place, while also providing separation and protection. The partitions are primarily welded to designated areas within the charging pile enclosure.

[0003] Chinese patent document CN115815809B discloses a welding device for a charging pile box partition. It includes a limiting part for positioning the box; a guide rail at the upper end of the limiting part, with symmetrical fixing parts for fixing the partition on the guide rail; a welding part for welding the partition and the box; and a support part at the lower end of the limiting part for supporting the limiting part, with a spacer part on the support part for determining the position of the partition. This invention combines the strict horizontal insertion of the partition into the box and outward expansion contact fixing with adsorption fixing to avoid partition skewing during welding. Furthermore, the internal spacer part ensures that the vertical distance between the partitions installed inside the box strictly meets design requirements, further ensuring the welding effect of the partitions inside the charging pile box.

[0004] While the device can fix and weld the partitions during use, it cannot weld multiple gaps in the partitions at the same time, which increases the processing time of the device. Furthermore, after the box is manually placed, the internal support will cause the box to tilt, affecting subsequent welding work. Summary of the Invention

[0005] The main objective of this invention is to provide a welding device for the partition of a charging pile box, which can effectively solve the problems of not being able to weld multiple gaps of the partition at the same time and the tilting that occurs when fixing the box.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A welding device for a charging pile box partition includes a workbench body, a drive mechanism fixedly installed on the upper end of the workbench body, two centering mechanisms on the upper side of the drive mechanism, and a welding mechanism on the upper side of the centering mechanism.

[0008] The driving mechanism includes a base, an electric cylinder is fixedly installed in the inner cavity of the base, a connecting rod is provided in the middle of the inner cavity of the base, threaded rods are fixedly installed at both ends of the connecting rod, threaded blocks are threadedly connected to the surfaces of the two threaded rods, a gear is provided on the lower side of the connecting rod, a slide block is fixedly installed on the upper end of the workbench body on the lower side of the gear, a rack is slidably installed in the inner cavity of the slide block, and the rack is fixedly connected to the output end of the electric cylinder.

[0009] Preferably, the threads of the two threaded rods are in opposite directions, the gear is rotatably mounted at the lower middle part of the base, and the gear is connected to the connecting rod by a belt.

[0010] Preferably, the centering mechanism includes an L-shaped plate, which is fixedly connected to a threaded block located on the same side. Two centering blocks are fixedly installed on the vertical end face of the L-shaped plate. The two centering blocks are symmetrically provided with inclined surfaces of the same angle. Two support rods are provided on the left and right sides of the L-shaped plate and fixedly installed on the upper end of the base. A support assembly is fixedly installed between the two support rods.

[0011] Preferably, the support assembly includes a support plate, a roller is rotatably mounted on the lower end of the support plate, two symmetrically opened slots are opened on the upper end of the support plate, a spring spring is fixedly installed in the inner cavity of each of the two slots, a triangular block is slidably installed in the inner cavity of each of the two slots, and several rollers are rotatably installed in the inner cavity of each of the two triangular blocks.

[0012] Preferably, the two triangular blocks are respectively connected to two elastic springs.

[0013] Preferably, the welding mechanism includes a support frame, which is fixedly connected to the rack. A housing is slidably mounted on the upper end of the support frame, and a motor is fixedly mounted on the upper end of the housing. A transmission assembly is provided in the middle of the inner cavity of the housing. A clamping frame is provided on the surface of the transmission assembly. A movable frame is provided on the lower side of the clamping frame. Two U-shaped rods are symmetrically provided on the lower end of the movable frame. A pressure block is fixedly mounted on the horizontal end face of the lower side of the clamping frame. Two welding guns are fixedly mounted on the lower ends of the two U-shaped rods.

[0014] Preferably, the transmission assembly includes a threaded tube, with a reciprocating solenoid rotatably mounted on the upper end of the threaded tube. Both the threaded tube and the reciprocating solenoid have two symmetrically shaped rectangular grooves on their arc-shaped inner walls. A reciprocating screw is provided inside the reciprocating solenoid. The upper end of the reciprocating screw is fixedly connected to the motor output end by a coupling. Two square grooves are symmetrically opened on the surface of the reciprocating screw. A threaded ring is threaded onto the surface of the reciprocating screw. Two telescopic blocks are rotatably mounted on the lower end of the threaded ring, with each telescopic block located within the inner cavity of one of the two square grooves.

[0015] Preferably, the threaded tube is threadedly connected to the movable frame, and the reciprocating threaded tube is threadedly connected to the clamping frame.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The welding mechanism of this invention can drive the reciprocating solenoid and the threaded tube to rotate sequentially through two downward-moving telescopic blocks. This allows the device to first fix the partition plate by the pressure block, and then allow the welding gun to move downward for welding. This ensures that the partition plate will not shift during welding, and multiple welding guns can be used to complete the welding at one time, improving the welding efficiency of the device. Furthermore, the initial position of the support frame will not affect the worker's upward placement of the box.

[0018] 2. The driving mechanism of this invention works in conjunction with the two centering mechanisms to clamp and fix the box placed on the support plate. During the clamping process, the triangular block can push the box to move, and the roller can roll on the surface of the box without scratching it. Centering the box not only makes it easier to clamp, but also facilitates the subsequent welding work. Attached Figure Description

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] like Figure 1 As shown, a welding device for a charging pile enclosure includes a workbench body 1, which supports the entire device to ensure its stability during use. A drive mechanism 2 is fixedly installed on the upper end of the workbench body 1. Two centering mechanisms 3 are provided on the upper side of the drive mechanism 2. The drive mechanism 2 and the centering mechanisms 3 work together to place the enclosure to be welded into the device, which can automatically center and clamp the enclosure, ensuring that the device can perform welding work normally. A welding mechanism 4 is provided on the upper side of the centering mechanism 3. By pushing the welding component downward, the four sides of the enclosure can be welded simultaneously, so that the enclosure can be welded in one go. The device has a certain working efficiency.

[0030] It should be noted that when the box is manually placed on the device, the box itself will be tilted, which is not only inconvenient to fix it, but also inconvenient to weld. By driving the centering mechanism 3 through the drive mechanism 2, the box can be centered while being clamped and fixed.

[0031] To further explain, in order to provide power to the two central mechanisms 3, such as Figure 2 and Figure 3As shown, the drive mechanism 2 includes a base 21, an electric cylinder 22 is fixedly installed in the inner cavity of the base 21, a connecting rod 23 is provided in the middle of the inner cavity of the base 21, and threaded rods 24 are fixedly installed at both ends of the connecting rod 23. The threads of the two threaded rods 24 are opposite in direction, and threaded blocks 25 are threadedly connected to the surfaces of the two threaded rods 24. A gear 26 is provided on the lower side of the connecting rod 23. The gear 26 is rotatably installed in the middle of the lower end of the base 21. The gear 26 is connected to the connecting rod 23 by a belt. The gear 26 can drive the connecting rod 23 to rotate, so that the two threaded rods 24 rotate simultaneously. Under the action of the threaded connection, the two threaded blocks 25 can drive the two threaded blocks 25 to move in opposite directions.

[0032] Then, a slide block 27 is fixedly installed on the upper end of the workbench body 1 on the lower side of the gear 26. A rack 28 is slidably installed in the inner cavity of the slide block 27. The rack 28 is fixedly connected to the output end of the electric cylinder 22. The slide block 27 can limit the rack 28 so that it can only move back and forth and cannot deviate. The rack 28 can mesh with the gear 26. Under the meshing action, when the rack 28 moves to the left, it can drive the gear 26 to rotate.

[0033] Specifically, the starting electric cylinder 22 can drive the rack 28 to move to the left. When the rack 28 contacts the gear 26, it can drive the gear 26 to rotate, so that the gear 26 can drive the two threaded rods 24 to rotate simultaneously through the connecting rod 23. The two threaded rods 24 can drive the two threaded blocks 25 to move in a direction closer to each other.

[0034] To further explain, in order to clamp and secure the box, such as Figure 4 As shown, the centering mechanism 3 includes an L-shaped plate 31, which is fixedly connected to a threaded block 25 located on the same side. The threaded block 25 can drive the two L-shaped plates 31 to move, so as to clamp and fix the box. Two centering blocks 32 are fixedly installed on the vertical end face of the L-shaped plate 31. The two centering blocks 32 are symmetrically provided with inclined surfaces of the same angle. Two support rods 33 are fixedly installed on the upper end of the base 21 on the left and right sides of the L-shaped plate 31. A support assembly 34 is fixedly installed between the two support rods 33. Through the cooperation of the support assembly 34 and the centering block 32, the box moves towards the center to achieve centering.

[0035] To further explain, in order to center the enclosure when securing it, such as... Figure 5As shown, the support assembly 34 includes a support plate 341. The welded box needs to be placed on the support plate 341. A roller 342 is rotatably mounted on the lower end of the support plate 341. The arc-shaped surface of the roller 342 contacts the horizontal end face of the L-shaped plate 31. When the L-shaped plate 31 moves, the roller 342 can reduce the loss between the components. Two opening slots 345 are symmetrically opened on the upper end of the support plate 341. A spring spring is fixedly installed in the inner cavity of each of the two opening slots 345. A triangular block 343 is slidably installed in the inner cavity of each of the two opening slots 345. By pushing the two triangular blocks 343 towards each other through the inclined plane, the box can gradually become centered.

[0036] Then, the two triangular blocks 343 are connected to the two spring springs respectively. Several rollers 344 are rotatably installed in the inner cavity of the two triangular blocks 343. The two spring springs can drive the two triangular blocks 343 to reset. The rollers 344 will contact the surface of the box. When the triangular blocks 343 push the box, it can prevent scratches from appearing on the surface of the box.

[0037] Specifically, the two threaded blocks 25 can drive the two L-shaped plates 31 to move, and the two centering blocks 32 will also move with the L-shaped plates 31. Through their inclined surfaces, they can push the two triangular blocks 343 to move towards each other. During the movement, the triangular blocks 343 will pull the elastic spring to extend it. The moving triangular blocks 343 will push the inclined box to move, gradually turning it into a centered state. When the two L-shaped plates 31 contact the box at the same time, they will clamp and fix it and keep it centered.

[0038] To further explain, in order to enable the welding of the partition, such as Figure 6 and Figure 7 As shown, the welding mechanism 4 includes a support frame 41. In order to facilitate the placement of the box on the device, the support frame 41 is located on the right side of the base 21 in the initial state. The support frame 41 is fixedly connected to the rack 28. The support frame 41 can move with the rack 28. A housing 42 is slidably installed on the upper end of the support frame 41. The welding position of the partition can be changed by adjusting the position of the housing 42. A motor 43 is fixedly installed on the upper end of the housing 42. A transmission component 44 is provided in the middle of the inner cavity of the housing 42. The transmission component 44 allows the device to fix the partition first and then perform welding to prevent the partition from moving and causing deviation during welding.

[0039] Then, a clamping frame 45 is provided on the surface of the transmission assembly 44, and a movable frame 46 is provided on the lower side of the clamping frame 45. The clamping frame 45 can be moved downward first by the transmission assembly 44, and then the movable frame 46 can be moved downward. Two U-shaped rods 47 are symmetrically provided at the lower end of the movable frame 46. A pressure block 48 is fixedly installed on the horizontal end face of the lower side of the clamping frame 45. When the pressure block 48 moves downward with the clamping frame 45, it will contact the upper end of the partition and fix it. Two welding guns 49 are fixedly installed at the lower ends of the two U-shaped rods 47. The two welding guns 49 will fit against the gap between the partition and the inner wall of the shell 42. When the movable frame 46 and the U-shaped rods 47 drive the four welding guns 49 to move downward, the partition can be welded.

[0040] To further explain, in order to fix the partition before welding, such as Figure 8 As shown, the transmission assembly 44 includes a threaded tube 441, which is threadedly connected to the movable frame 46. When the threaded tube 441 rotates, it can drive the movable frame 46 to move downward. A reciprocating solenoid 442 is rotatably installed on the upper end of the threaded tube 441. The reciprocating solenoid 442 is threadedly connected to the clamping frame 45. When the reciprocating solenoid 442 rotates, it can drive the clamping frame 45 to move downward. Two rectangular slots are symmetrically opened on the arc-shaped inner walls of both the threaded tube 441 and the reciprocating solenoid 442. A reciprocating screw 443 is provided in the inner cavity of the reciprocating solenoid 442. The upper end of the reciprocating screw 443 is fixedly connected to the output end of the motor 43 by a coupling. Starting the motor 43 can drive the reciprocating screw 443 to rotate.

[0041] Then, two square grooves 444 are symmetrically opened on the surface of the reciprocating screw 443. A threaded ring 445 is threadedly connected to the surface of the reciprocating screw 443. The upper end of the threaded ring 445 is fixedly connected to the upper inner wall of the support frame 41 by a telescopic tube. When the reciprocating screw 443 rotates, it can drive the threaded ring 445 to move downward. Two telescopic blocks 446 are rotatably installed at the lower end of the threaded ring 445. The two telescopic blocks 446 are located in the inner cavity of the two square grooves 444 respectively. While the telescopic blocks 446 move downward with the threaded ring 445, they also rotate with the reciprocating screw 443. At the same time, they can drive the reciprocating screw tube 442 and the threaded tube 441 to rotate through the rectangular grooves respectively.

[0042] Specifically, the starter motor 43 drives the reciprocating screw 443 to rotate, causing the threaded ring 445 and two telescopic blocks 446 to move downwards. As the two telescopic blocks 446 move downwards, they rotate with the reciprocating screw 443, driving the reciprocating solenoid 442 to rotate through the rectangular groove. When the reciprocating solenoid 442 rotates, it drives the clamping frame 45 to move downwards. The clamping frame 45 drives the pressure block 48 to move downwards simultaneously. When the pressure block 48 contacts the partition, it fixes it. When the two telescopic blocks 446 move to the inner cavity of the threaded tube 441, they drive the threaded tube 441 to rotate through the rectangular groove. The threaded tube 441 drives the movable frame 46 and the U-shaped rod 47 to move downwards. Several welding guns 49 move downwards with the U-shaped rod 47, gradually welding multiple gaps in the partition.

[0043] The specific method of using the present invention is as follows: the box to be welded is placed on two support plates 341, the electric cylinder 22 is started to drive the rack 28 to move to the left, the rack 28 can drive the support frame 41 to move directly above the box, when the rack 28 contacts the gear 26, it can drive the gear 26 to rotate, so that the gear 26 can drive the two threaded rods 24 to rotate simultaneously through the connecting rod 23, and the two threaded rods 24 can drive the two threaded blocks 25 to move in a direction closer to each other;

[0044] The two threaded blocks 25 can drive the two L-shaped plates 31 to move, and the two centering blocks 32 will also move with the L-shaped plates 31. Through their inclined surfaces, they can push the two triangular blocks 343 to move towards each other. During the movement, the triangular blocks 343 will pull the elastic spring to extend it. The moving triangular blocks 343 will push the inclined box to move, gradually turning it into a centered state. When the two L-shaped plates 31 contact the box at the same time, they will clamp and fix it and keep it centered.

[0045] Then, starting the motor 43 drives the reciprocating screw 443 to rotate, causing the threaded ring 445 and the two telescopic blocks 446 to move downwards. As the two telescopic blocks 446 move downwards, they rotate with the reciprocating screw 443, driving the reciprocating tube 442 to rotate through the rectangular groove. When the reciprocating tube 442 rotates, it drives the clamping frame 45 to move downwards. The clamping frame 45 drives the pressure block 48 to move downwards at the same time. When the pressure block 48 contacts the partition, it will fix it. When the two telescopic blocks 446 move to the inner cavity of the threaded tube 441, they will drive the threaded tube 441 to rotate through the rectangular groove. The threaded tube 441 will drive the movable frame 46 and the U-shaped rod 47 to move downwards. Several welding guns 49 will move downwards with the U-shaped rod 47, gradually welding multiple gaps in the partition.

[0046] It should be noted that the specific installation method, circuit connection method and control method of the electric cylinder 22 and the motor 43 in this invention are all conventional designs, and will not be described in detail in this invention.
