Description

Technical Field

[0001] This utility model belongs to the field of power distribution cabinet manufacturing technology, and in particular relates to a welding auxiliary positioning device for power distribution cabinet canopy. Background Technology

[0002] For some outdoor distribution cabinets, a canopy is welded to the top. The welding of the canopy to the distribution cabinet usually involves holding the canopy placed on the distribution cabinet by hand and then welding it with a welding gun. The stability of the canopy is difficult to guarantee, which may lead to misalignment and require re-welding. Therefore, we have proposed an auxiliary positioning device for welding distribution cabinet canopies. It uses a mechanical structure to press and fix the canopy on top of the distribution cabinet, reducing the input of manpower and improving welding efficiency and accuracy. Utility Model Content

[0003] The purpose of this utility model is to provide a welding auxiliary positioning device for a distribution cabinet canopy, which has the advantages of using a mechanical structure to press and fix the canopy on top of the distribution cabinet, reducing manpower input and improving welding efficiency and accuracy, thereby solving the above-mentioned technical problems.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A welding auxiliary positioning device for a power distribution cabinet canopy includes a base frame, a limiting cavity is provided on the top of the base frame, a cabinet is placed in the inner cavity of the limiting cavity, an L-shaped frame is provided on the top of the base frame, an inverted U-shaped frame is fixedly connected to the inner side of the L-shaped frame, L-shaped clamps are provided on both sides of the inverted U-shaped frame, a canopy body is clamped between the two L-shaped clamps, the canopy body is attached to the top of the cabinet, a driving component is provided between the two L-shaped clamps and the inverted U-shaped frame, and a lifting component is provided between the L-shaped frame and the base frame.

[0005] Preferably, the drive assembly includes a bidirectional threaded rod rotatably connected to the inner cavity of the inverted U-shaped frame. Both sides of the surface of the bidirectional threaded rod are threaded with threaded sleeves. The opposite sides of the two L-shaped clamps are rotatably connected with diagonal braces via a rotating shaft. One end of the diagonal brace is rotatably connected to the threaded sleeve via a rotating shaft. A motor is fixedly installed on the outer side of the inverted U-shaped frame, and the output shaft of the motor is fixedly connected to the bidirectional threaded rod.

[0006] Preferably, two symmetrical fixing sleeves are provided between the two L-shaped clamps. The top of the fixing sleeve is fixedly connected to the inverted U-shaped frame, and two symmetrical slide bars are slidably connected to the inner cavity of the fixing sleeve. One end of the slide bar is fixedly connected to the L-shaped clamp.

[0007] Preferably, the lifting assembly includes a cylinder fixedly mounted on a base frame, the output end of the cylinder is fixedly connected to a connecting plate, and one side of the connecting plate is fixedly connected to an L-shaped frame.

[0008] Preferably, the rear side of the base frame is fixedly connected to two symmetrical fixed rails, and the surface of the fixed rails is slidably connected to a sliding sleeve, one side of which is fixedly connected to the L-shaped frame.

[0009] The beneficial effects of this utility model are:

[0010] 1. This utility model places the cabinet inside the limiting cavity, then places the canopy body between two L-shaped clamps. The driving component drives the two L-shaped clamps to hold the canopy body. Then, the lifting component lowers the L-shaped frame, the inverted U-shaped frame, the L-shaped clamps, and the canopy body, so that the canopy body is pressed on top of the cabinet, thus achieving the positioning of the cabinet and the canopy body. Then, the welding gun is picked up and welding is performed around the contact position between the cabinet and the canopy body. During the welding process, neither the cabinet nor the canopy body will shift to the side. This achieves the purpose of using a mechanical structure to press the canopy down and fix it on top of the distribution cabinet, reducing the input of manpower and improving welding efficiency and accuracy.

[0011] 2. By using the fixed sleeve and the slide bar in combination, the slide bar will slide in the inner cavity of the fixed sleeve during the movement of the L-shaped clamp, providing support and guidance for the movement of the L-shaped clamp and improving the stability of the movement of the L-shaped clamp.

[0012] 3. By using the sliding sleeve in conjunction with the fixed rail, the sliding sleeve slides on the surface of the fixed rail during the up-and-down movement of the L-shaped frame, which limits the offset of the L-shaped frame and improves the stability of the up-and-down movement of the L-shaped frame.

[0020] In the following description, embodiments of the welding auxiliary positioning device for the distribution cabinet canopy of this utility model will be described with reference to the accompanying drawings.

[0021] Figure 1-4 This invention illustrates an embodiment of a welding auxiliary positioning device for a distribution cabinet canopy, comprising a base frame 1, a limiting cavity 2 at the top of the base frame 1, a cabinet body 3 placed within the limiting cavity 2, an L-shaped frame 4 at the top of the base frame 1, an inverted U-shaped frame 5 fixedly connected to the inner side of the L-shaped frame 4, L-shaped clamping plates 6 on both sides of the inverted U-shaped frame 5, a canopy body 7 clamped between the two L-shaped clamping plates 6, the canopy body 7 fitting against the top of the cabinet body 3, and a driving assembly 8 between the two L-shaped clamping plates 6 and the inverted U-shaped frame 5. The drive assembly 8 includes a bidirectional threaded rod 81 rotatably connected to the inner cavity of the inverted U-shaped frame 5. Threaded sleeves 82 are threadedly connected to both sides of the surface of the bidirectional threaded rod 81. Diagonal braces 83 are rotatably connected to opposite sides of the two L-shaped clamps 6 via shafts. One end of each diagonal brace 83 is rotatably connected to the threaded sleeve 82 via a shaft. A motor 84 is fixedly mounted on the outer side of the inverted U-shaped frame 5. The output shaft of the motor 84 is fixedly connected to the bidirectional threaded rod 81. Two symmetrical fixing sleeves 85 are provided between the two L-shaped clamps 6. The top of each fixing sleeve 85... The fixed sleeve 85 is fixedly connected to the inverted U-shaped frame 5. Two symmetrical slide bars 86 are slidably connected to the inner cavity of the fixed sleeve 85. One end of each slide bar 86 is fixedly connected to the L-shaped clamp 6. Through the cooperation of the fixed sleeve 85 and the slide bars 86, the L-shaped clamp 6 moves, causing the slide bars 86 to slide within the inner cavity of the fixed sleeve 85, providing support and guidance for the movement of the L-shaped clamp 6 and improving the stability of its movement. A lifting assembly 9 is provided between the L-shaped frame 4 and the base frame 1. The lifting assembly 9 includes a cylinder 9 fixedly mounted on the base frame 1. 1. A connecting plate 92 is fixedly connected to the output end of cylinder 91. One side of the connecting plate 92 is fixedly connected to the L-shaped frame 4. Two symmetrical fixed rails 94 are fixedly connected to the rear side of the base frame 1. A sliding sleeve 93 is slidably connected to the surface of the fixed rail 94. One side of the sliding sleeve 93 is fixedly connected to the L-shaped frame 4. Through the cooperation of the sliding sleeve 93 and the fixed rail 94, the sliding sleeve 93 slides on the surface of the fixed rail 94 during the up and down movement of the L-shaped frame 4, which limits the offset of the L-shaped frame 4 and improves the stability of the up and down movement of the L-shaped frame 4.

[0022] Working principle: When using this utility model, the cabinet body 3 is placed in the inner cavity of the limiting cavity 2, and then the canopy body 7 is placed between the two L-shaped clamping plates 6. The motor 84 rotates the bidirectional threaded rod 81, causing the two threaded sleeves 82 to move in opposite directions. The rotation of the diagonal brace 83 causes the two L-shaped clamping plates 6 to move towards each other, clamping the canopy body 7. Then the cylinder 91 retracts, and the connecting plate 92 causes the L-shaped frame 4, the inverted U-shaped frame 5, the L-shaped clamping plates 6 and the canopy body 7 to descend, so that the canopy body 7 presses on top of the cabinet body 3, realizing the positioning of the cabinet body 3 and the canopy body 7. Then the welding gun is picked up and welding is performed around the contact position between the cabinet body 3 and the canopy body 7. During the welding process, neither the cabinet body 3 nor the canopy body 7 will shift to the side.

[0023] In summary, this auxiliary positioning device for welding the distribution cabinet canopy works by placing the cabinet body 3 inside the limiting cavity 2, then placing the canopy body 7 between two L-shaped clamps 6. The drive assembly 8 drives the two L-shaped clamps 6 to hold the canopy body 7 in place. Then, the lifting assembly 9 lowers the L-shaped frame 4, the inverted U-shaped frame 5, the L-shaped clamps 6, and the canopy body 7, pressing the canopy body 7 onto the cabinet body 3, thus positioning the cabinet body 3 and the canopy body 7. Then, the welding torch is picked up and welding is performed around the contact point between the cabinet body 3 and the canopy body 7. During the welding process, neither the cabinet body 3 nor the canopy body 7 will shift laterally. This achieves the goal of using a mechanical structure to press and fix the canopy on top of the distribution cabinet, reducing manpower input and improving welding efficiency and accuracy.
