Description

Technical Field

[0001] This utility model relates to the field of auxiliary tooling technology for electrical cabinet welding, specifically to a welding positioning device for electrical cabinets. Background Technology

[0002] During the manufacturing process of distribution cabinets, the welding quality of the side frame spare parts directly affects the overall structural strength and stability of the distribution cabinet.

[0003] Currently, the welding positioning of spare parts on the side frame of the distribution cabinet mainly relies on operators' experience to manually measure and judge, determining the welding position through methods such as marking lines and visual observation. However, this traditional manual positioning method has significant drawbacks:

[0004] On the one hand, due to the lack of precise positioning benchmarks, it is difficult to ensure the consistency of welding positions, which can easily lead to welding deviations. This results in problems such as dimensional errors and structural asymmetry after the side frame spare parts are welded, affecting the assembly accuracy and appearance quality of the distribution cabinet.

[0005] On the other hand, during the manual positioning process, operators need to repeatedly adjust the position of spare parts, which is cumbersome, inefficient, and requires a high level of experience and skills from the operators, making it difficult to meet the needs of modern large-scale production. Therefore, a distribution cabinet welding positioning device is provided to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this utility model is to provide a welding positioning device for power distribution cabinets to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A welding positioning device for a power distribution cabinet includes a positioning frame for supporting and positioning the power distribution cabinet upright. Two limiting mechanisms A are symmetrically arranged at the left end of the positioning frame, and two limiting mechanisms B are symmetrically arranged at the right end of the positioning frame. The limiting mechanisms B cooperate with the limiting mechanisms A to block and limit the two sides of the power distribution cabinet upright placed in the positioning frame. The positioning frame is provided with a plurality of slidably adjustable inner horizontal frame auxiliary positioning mechanisms. The two corresponding inner horizontal frame auxiliary positioning mechanisms work together to position the inner horizontal frame that needs to be welded between two power distribution cabinet uprights, so that the inner horizontal frame is perpendicular to the power distribution cabinet upright.

[0009] Preferably, the positioning frame includes two horizontal supports. Two connecting rods are fixedly installed on the front surface of the rear horizontal support. The connecting rods pass through the front horizontal support, and two nuts are screwed onto the outer surface of the front end of the connecting rods. The two nuts are clamped on the front and rear sides of the horizontal support. L-shaped support plates are fixedly installed on both the left and right ends of the horizontal support. Each L-shaped support plate has an adapter groove, which is used to support the bottom of the power distribution cabinet frame.

[0010] Preferably, the limiting mechanism A includes an L-shaped block fixedly installed on the left surface of the L-shaped support plate on the left side, and the L-shaped block acts as a blocking and limiting block on the left end of the distribution cabinet frame placed on the L-shaped support plate.

[0011] Preferably, the upper surface of the L-shaped block is integrally formed with a vertical block, which serves to block and limit the left end of the side plate of the power distribution cabinet that needs to be welded between the two power distribution cabinet uprights.

[0012] Preferably, the limiting mechanism B includes a rotating shaft rotatably connected to the L-shaped support plate on the right side. A baffle is fixedly installed at the right end of the rotating shaft. There is damping between the rotating shaft and the L-shaped support plate. The L-shaped support plate cooperates with the L-shaped block to form a blocking and limiting effect on the left and right sides of the distribution cabinet frame placed on the L-shaped support plate.

[0013] Preferably, the upper surface of the crossbeam is fixedly mounted with a slide rail marked with length. The inner crossbeam auxiliary positioning mechanism includes a slide table slidably mounted on the slide rail. A threaded post is threadedly mounted through the upper surface of the slide table. The lower surface of the threaded post is fitted with the upper surface of the slide rail to fix the slide table. A handle is fixedly mounted on the upper surface of the threaded post. A convex block is fixedly mounted on the upper surface of the slide table. The convex block is located to the right of the handle.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention, by setting a positioning frame with an L-shaped support plate and an adapter slot, can precisely support the bottom of the upright frame using the adapter slot. Combined with the L-shaped block of the left-side fixed limiting mechanism A and the baffle of the right-side rotatable limiting mechanism B, a rigid positioning benchmark is formed for the left and right sides of the distribution cabinet upright frame, avoiding the randomness of manual adjustments. Simultaneously, the slide table of the inner horizontal frame auxiliary positioning mechanism slides along a rail with length markings, and combined with the structural design of the convex block engaging the inner side of the horizontal frame, it ensures that the inner horizontal frame of the distribution cabinet is perpendicular to the upright frame and that the spacing accuracy meets the standards. This multi-dimensional positioning structure fundamentally solves the problems of dimensional errors and structural asymmetry caused by the lack of quantitative benchmarks in traditional methods, significantly improving the accuracy and consistency of welding positions.

[0016] In addition, rotational positioning is achieved through the rotating shaft of the limiting mechanism B in conjunction with the damping pad. The operator only needs to push the upright to fit against the left limiting mechanism A, and then rotate the baffle to quickly complete the right-side positioning. When positioning the inner cross frame, the length marking of the slide rail and the handle design of the threaded column make the position adjustment and locking operation of the slide table convenient and efficient, greatly reducing the manual adjustment time.

[0017] In addition, the horizontal beam of the positioning frame can be adjusted by connecting rods and nuts to adjust the spacing. Combined with the sliding adjustment function of the inner horizontal beam auxiliary positioning mechanism, it can be adapted to inner horizontal beams of different lengths and installation positions to meet diverse production needs.

[0018] The entire positioning device, through standardized positioning procedures and adjustable structures, significantly reduces reliance on operator experience, improves welding efficiency, and enhances the equipment's versatility, making it more adaptable to the high efficiency and flexibility requirements of modern large-scale production.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a technical solution:

[0029] A welding positioning device for a power distribution cabinet, combined with Figure 1 and Figure 7 As shown, the device includes a positioning frame 1 for supporting and positioning the distribution cabinet upright. Two limiting mechanisms A2 are symmetrically arranged at the left end of the positioning frame 1, and two limiting mechanisms B3 are symmetrically arranged at the right end of the positioning frame 1. The limiting mechanisms B3 cooperate with the limiting mechanisms A2 to block and limit the distribution cabinet upright placed in the positioning frame 1 on both sides. The positioning frame 1 is provided with multiple slidingly adjustable inner horizontal frame auxiliary positioning mechanisms 4. The two corresponding inner horizontal frame auxiliary positioning mechanisms 4 are used in conjunction to position the inner horizontal frame that needs to be welded between the two distribution cabinet uprights, so that the inner horizontal frame is perpendicular to the distribution cabinet upright.

[0030] It should be noted that, as Figure 1 As shown, the positioning frame 1 includes two horizontal supports 11. Two connecting rods 12 are fixedly installed on the front surface of the rear horizontal support 11. The connecting rods 12 pass through the front horizontal support 11, and two nuts 121 are screwed onto the outer surface of the front end of the connecting rods 12. The two nuts 121 are clamped on the front and rear sides of the horizontal support 11. L-shaped support plates 13 are fixedly installed on both the left and right ends of the horizontal support 11. Each L-shaped support plate 13 has an adapter groove 131. The adapter groove 131 is used to support the bottom of the distribution cabinet frame. In actual use, the distance between the two horizontal supports 11 can be adjusted by the position of the two nuts 121 on the connecting rods 12, thereby changing the distance between the two distribution cabinet frames placed on the L-shaped support plates 13. This facilitates the installation of horizontal supports of different lengths in the distribution cabinet and increases the overall applicability of the positioning device.

[0031] Before using this device to weld spare parts for the distribution cabinet, adjust the distance between the left and right auxiliary positioning mechanisms 4 of the inner horizontal frame according to the installation requirements of the inner horizontal frame of the distribution cabinet, so as to use the auxiliary positioning mechanism 4 of the inner horizontal frame to position the inner horizontal frame of the distribution cabinet.

[0032] In use, place the two distribution cabinet uprights horizontally between the left and right L-shaped support plates 13, so that the bottom of the uprights is inserted into the adapter slots 131 and the outer side is in contact with the inner side of the L-shaped support plate 13. Then push the uprights so that their left ends are in contact with the limiting mechanism A2. Then rotate and adjust the limiting mechanism B3 so that it is in contact with the right side of the uprights to form a positioning. Next, fasten the inner crossbar of the distribution cabinet between the corresponding inner crossbar auxiliary positioning mechanisms 4 at the front and rear. With the help of the positioning of the inner crossbar auxiliary positioning mechanisms 4, the crossbar is made perpendicular to the uprights for standard welding. After welding multiple crossbeams, place the side panel of the distribution cabinet between two uprights (using the supporting edge of the uprights). Push the side panel to align its left end with the left end of the upright. Press and fix it, then pre-weld the positioning at the four corners, and then weld the remaining parts. After the side panel welding is completed, rotate the limiting mechanism B3 to disengage it from the distribution cabinet uprights. Then, remove the welded distribution cabinet parts from the positioning device from the right side. This positioning device can play a standard positioning role when welding distribution cabinet body spare parts. Compared with the previous manual welding based on the operator's experience, it can improve welding efficiency and quality, and make the overall welding more standardized.

[0033] Specifically, combined Figure 1 and Figure 7 As shown, the limiting mechanism A2 includes an L-shaped block 21 fixedly installed on the left surface of the left L-shaped support plate 13. The L-shaped block 21 acts as a blocking and limiting mechanism on the left end of the distribution cabinet stand placed on the L-shaped support plate 13.

[0034] Specifically, combined Figure 1 and Figure 7 As shown, the upper surface of the L-shaped block 21 is integrally formed with a vertical block 22, which acts as a blocking and limiting force on the left end of the side plate of the power distribution cabinet that needs to be welded between the two power distribution cabinet uprights.

[0035] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, the limiting mechanism B3 includes a rotating shaft 31 rotatably connected to the right-side L-shaped support plate 13. A baffle 32 is fixedly installed at the right end of the rotating shaft 31, in conjunction with... Figure 3 As shown, a blocking component 33 and a nut are welded and fixedly installed on the outer surface of the rotating shaft 31. Multiple damping pads 34 are provided between the nut and the L-shaped support plate 13 and between the blocking component 33 and the L-shaped support plate 13. The damping pads 34 are sleeved on the outer surface of the rotating shaft 31, which enables damping between the rotating shaft 31 and the L-shaped support plate 13. This ensures that the baffle 32 can maintain its position when it is not subjected to external force, and facilitates the baffle 32 to cooperate with the L-shaped block 21 after rotating its position, forming a blocking limit on the left and right sides of the distribution cabinet frame placed on the L-shaped support plate 13.

[0036] Finally, to accommodate the diverse installation requirements of different distribution cabinets for the internal crossbeams, a slide rail 111 with length markings is installed on the upper surface of the crossbeam 11 (in conjunction with...). Figure 1 , Figure 5 and Figure 6 As shown), it is used to precisely adjust the position of the inner crossbeam auxiliary positioning mechanism 4.

[0037] The inner crossbeam auxiliary positioning mechanism 4 includes a slide table 41 that can slide along the slide rail 111, with a threaded post 42 threaded through its upper part. By rotating the threaded post 42 so that its lower end fits tightly against the upper surface of the slide rail 111, the position of the slide table 41 can be locked. For ease of operation, a handle 421 is provided on the top of the threaded post 42, optimizing the convenience of manual adjustment. A convex block 43 is fixedly installed on the right side of the upper surface of the slide table 41, and the height of its protruding part is adapted to the inner width of the crossbeam inside the distribution cabinet.

[0038] In actual use, the operator can quickly position the slide table 41 according to the design spacing of the crossbeams inside the distribution cabinet by means of the length markings on the slide rail 111, and then tighten the threaded post 42 with the handle 421 to complete the fixation. At this time, the protruding part of the convex block 43 can accurately engage with the inside of the crossbeam, forming a stable support and ensuring that the crossbeams maintain the preset vertical angle and spacing accuracy during the welding process.

[0039] This design not only meets the production needs of power distribution cabinets of different specifications, but also significantly improves the efficiency and accuracy of positioning operations by combining length markings with an adjustable structure, providing a reliable guarantee for the standardized welding of power distribution cabinets.
