Description

Technical Field

[0001] This invention relates to the field of electrical equipment processing technology, and in particular to a welding positioning device for electrical control cabinets. Background Technology

[0002] In the manufacturing of electrical control cabinets, the frame is often welded from structural steel. The welding quality between the frame and the panel directly determines the structural stability and service life of the cabinet. The accuracy and ease of welding positioning are crucial for ensuring welding quality. However, traditional welding positioning methods for electrical control cabinets have many technical defects, severely restricting production efficiency and product quality. Specific problems are as follows: Existing positioning devices mostly rely on cylinder drive or manual clamps to achieve positioning. This not only requires complex air circuit connections or cumbersome manual locking steps, but also requires multiple adjustments to complete the positioning of the frame and panel. Moreover, the positioning components of such devices have poor linkage, and the problem of asynchronous positioning points is prone to occur during the adjustment process, resulting in low positioning efficiency. Meanwhile, the clamping structure is mostly a rigid design and lacks elastic buffering. This not only easily causes deformation of thin-walled profiles, but also makes it difficult to maintain stable clamping under welding vibration environment. This leads to the displacement of the frame during welding, causing the verticality and squareness deviation of the cabinet to exceed the standard, which affects the installation accuracy of subsequent electrical components. In addition, when replacing the control cabinet frame and panel of different models, it is necessary to change the position of the entire positioning fixture, which is time-consuming and labor-intensive. Summary of the Invention

The device achieves precise adjustment of the positioning mechanism through a drive mechanism, quickly clamps the frame by cooperating with the positioning block and the positioning frame, and accurately positions the welding position by combining the positioning plate and the positioning strip. With the height adjustment function of the push cylinder, it effectively improves the positioning accuracy and operation efficiency of welding electrical control cabinets and is suitable for processing various cabinet specifications.

A set of locking blocks corresponding to the locking grooves are provided on both sides of the locking seat. The locking blocks extend into the interior of the locking grooves.

[0010] Furthermore, a transverse guide plate is provided on one side of the sliding seat, and a sliding hole is opened on the inner side of the guide plate. The sliding hole is an oval hole structure. Two parallel sliding holes are respectively installed with a support block on the inner side. The inner side of the support block and the oval hole are opposite to each other. A connecting rod is installed on the inner side of another sliding hole, and a locking bolt is installed on the top of the support block.

[0011] Furthermore, a horizontal positioning strip is provided on each side of the connecting rod, a limiting block corresponding to the sliding hole is provided in the middle of the connecting rod, a locking bolt is also installed on one side of the limiting block, a vertical extension rod is provided at the bottom of the support block, and a horizontal positioning plate is provided at the bottom of the extension rod.

Specifically, the positioning plate and positioning strip position the welding positions of the frame and panel from the top and bottom respectively, ensuring precise alignment of the welding points; the cooperation between the connecting rod and the guide plate enables flexible adjustment of the positioning strip, adapting to selective positioning of different positions of the frame and panel; the locking bolts ensure that the position is stable after adjustment, avoiding displacement during welding that affects accuracy; the overall positioning mechanism achieves coordinated positioning of multiple parts of the cabinet, improving welding consistency and avoiding problems such as incomplete welding or missing welding caused by positioning deviation.

[0013] The positioning mechanism is adjusted by a drive mechanism consisting of an electric motor, threaded rods, and driven bevel gears. The meshing transmission between the drive bevel gears and driven bevel gears enables the synchronous rotation of multiple threaded rods, which in turn drives the sliding seat to move precisely in the horizontal and vertical directions. This ensures the synchronous adjustment of the positioning mechanism and allows for adjustment according to control cabinets of different sizes. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: Please refer to Figures 1 to 10 : This invention proposes a welding positioning device for an electrical control cabinet, comprising: a control body 1, of which there are two; a positioning body 2 rotatably connected to the inner side of each control body 1; a rotating block, cylindrical in structure, extending into the interior of the control body 1, located at the center of one side of each positioning body 2; a set of horizontally and vertically arranged electric motors 301 mounted on the edge of each positioning body 2; bolt mounting holes formed at the corners of each electric motor 301 for mounting matching bolts; and a set of horizontally and vertically arranged sliding grooves, T-shaped in structure, formed on the base of each positioning body 2; a sliding seat 401 mounted on the inner side of each sliding groove; and a movably connected positioning frame 405 mounted on one side of each sliding seat 401; the sliding grooves on the positioning body 2 are T-shaped; a threaded hole is formed on one side of each sliding seat 401; and a threaded rod 302 is inserted into the threaded hole; one side of the threaded rod 302 is connected to the electric motor 301. The drive shaft of motor 301 is connected, and the connection position of the drive shaft and threaded rod 302 is set according to the keyway positioning of the prior art. A driven bevel gear 303 is installed on one side of the threaded rod 302. The electric motor 301, threaded rod 302, and driven bevel gear 303 cooperate to form the drive mechanism 3. A horizontal rotating shaft is installed in the middle of the positioning body 2, and a drive bevel gear 201 is installed on the outer side of the rotating shaft. The connection position of the drive bevel gear 201 and the rotating shaft is set according to the positioning structure of the prior art. The drive bevel gear 201 and the driven bevel gear 303 mesh. The drive bevel gear 201 drives a group of driven bevel gears 303 to rotate simultaneously. Specifically, the sliding groove provides stable guidance for the sliding seat 401 and prevents the sliding seat 401 from deviating when sliding. Through the meshing transmission of the drive bevel gear 201 and the driven bevel gear 303, the synchronous rotation of multiple threaded rods 302 is realized, which drives the sliding seat 401 to move accurately in the horizontal and vertical directions, ensuring the synchronous adjustment of the positioning mechanism 4. It can be adjusted according to the control cabinet of different sizes. In this embodiment, a positioning block 404 is provided on one side of the sliding seat 401. The positioning block 404 has a rectangular structure and positions the upper and lower frames of the electrical control cabinet. Specifically, the rectangular positioning block 404 fits against the edge of the frame, which can quickly determine the reference position of the frame, avoid the error of manual alignment, and provide a reference for subsequent clamping actions to ensure the initial positioning accuracy of the frame. A set of mounting holes is opened on one side of the sliding seat 401, and a positioning rod 402 is inserted inside the mounting holes. A sliding groove is opened on one side of the sliding seat 401. The sliding groove has a T-shaped structure. A sliding block corresponding to the sliding groove is provided on one side of the positioning frame 405. The sliding block extends into the sliding groove. A sliding hole corresponding to the positioning rod 402 is opened in the middle of the sliding block. A support spring is installed on the outer side of the positioning rod 402, passing through the interior of the sliding hole. The support spring pushes the positioning frame 405 to move closer to the positioning block 404. The positioning block 404 cooperates with the positioning frame 405 to quickly position and clamp the upper and lower frames of the electrical control cabinet. Specifically, the sliding groove and the sliding block cooperate to ensure that the positioning frame 405 moves smoothly along a straight line. The elastic force of the support spring causes the positioning frame 405 to automatically move closer to the positioning block 404, realizing the rapid clamping of the frame and reducing the welding positioning operation steps. At the same time, the elastic clamping can avoid the deformation of the frame caused by rigid clamping. A bending block is provided on one side of the positioning frame 405. The bending block facilitates the installation of the frame. Specifically, the bending block creates clearance space, so that the frame can be placed into the positioning area without precise alignment during installation, reducing the difficulty of operation. In this embodiment, a guide frame is provided on one side of the positioning frame 405. The guide frame has a U-shaped structure. A locking seat 406 is inserted inside the guide frame.

The support spring is located inside the guide frame. A set of evenly distributed locking grooves are opened on both sides of the sliding seat 401. The locking grooves have a rectangular structure. A set of locking blocks corresponding to the locking grooves are provided on both sides of the locking seat 406. The support spring pushes the locking seat 406 to reset. The locking blocks extend into the interior of the locking grooves. Specifically, the support spring pushes the locking blocks to embed into the locking grooves, realizing the rigid and rapid locking of the positioning frame 405 and the sliding seat 401, preventing the positioning frame 405 from loosening due to welding vibration. The lifting rod 407 can unlock the positioning frame 405. The operation is convenient and suitable for clamping and fixing skeletons of different thicknesses.

[0020] In this embodiment, a transverse guide plate 403 is provided on one side of the sliding seat 401. A sliding hole is formed on the inner side of the guide plate 403. The sliding hole is an oval hole structure. A support block 408 is installed on the inner side of two parallel sliding holes. The inner surfaces of the support block 408 and the oval hole are opposite to each other. A connecting rod 410 is installed on the inner side of another sliding hole. The sliding hole cooperates with the support block 408 to position the positioning plate 409 circumferentially. The two parallel sliding holes provide sufficient lateral adjustment space for the support block 408. A locking bolt is installed on the top of the support block 408. The positioning is completed by tightening the locking bolt. The positioning plate 409 is locked in place. Specifically, its oval hole structure provides a wide range of lateral adjustment space for the support block 408 and connecting rod 410, adapting to selective positioning of different positions on the frame and panel. The support block 408, with the locking bolt, can fix the positioning plate 409 in any position, ensuring stable support and welding positioning for bottom frames of different specifications, improving device compatibility. The connecting rod 410 has a lateral positioning strip 411 on each side, and a limiting block corresponding to the sliding hole in the middle. The limiting block, in conjunction with the sliding hole, provides circumferential positioning. A locking bolt is also installed on one side of the limiting block; tightening the locking bolt completes the positioning. Positioning bar 411 is locked in position. The sliding hole of guide plate 403 on another part of positioning bar 411 positions the connecting rod 410 circumferentially and provides sufficient lateral adjustment space for positioning bar 411. A vertical extension rod is provided at the bottom of support block 408, and a lateral positioning plate 409 is provided at the bottom of the extension rod. Sliding seat 401, positioning rod 402, guide plate 403, positioning block 404, positioning frame 405, locking seat 406, lifting rod 407, support block 408, positioning plate 409, connecting rod 410, and positioning bar 411 cooperate to form positioning mechanism 4. Positioning plate 409 positions the bottom lateral frame and surface... The plate provides support, while the positioning plate 409 positions the welding positions of the horizontal frame and the panel. The positioning strip 411 positions the upper frame and the panel vertically for welding. Specifically, the positioning plate 409 and the positioning strip 411 position the welding positions of the frame and the panel from the top and bottom, respectively, to ensure accurate alignment of the welding points. The cooperation between the connecting rod 410 and the guide plate 403 enables the flexible adjustment of the positioning strip 411, adapting to the selective positioning of different positions of the frame and the panel. The locking bolts ensure that the position is stable after adjustment, avoiding displacement during welding and affecting accuracy. The overall positioning mechanism 4 achieves coordinated positioning of multiple parts of the cabinet, improving welding consistency. In this embodiment, a stabilizing plate is provided at the bottom of the control body 1. A vertical push cylinder 5 is installed on one side of the stabilizing plate. A lifting plate 501 is installed above the push rod of the push cylinder 5. Specifically, the push cylinder 5 can drive the lifting plate 501 to move vertically up and down, which can adjust the overall height of the electrical control cabinet according to the welding requirements, and facilitate the unloading and fine-tuning of the electrical control cabinet.

[0021] Example 2, based on Example 1, such as Figures 1-6 As shown, the drive unit inside the control body 1 is connected to the middle position of the positioning body 2. The positioning body 2 is driven to rotate by the drive unit inside the control body 1, thus completing the rotation of the welding workpiece.

[0022] The working principle of this embodiment: According to the dimensions of the electrical control cabinet to be welded, start the electric motor 301, drive the bevel gear 201 to mesh with the driven bevel gear 303, drive the threaded rod 302 to rotate, and make the sliding seat 401 move along the sliding groove of the positioning body 2, adjust the overall spacing of the positioning mechanism 4 to match the cabinet frame size; The sliding support block 408 and the connecting rod 410 move along the oval hole of the guide plate 403, and adjust the positioning plate 409 and the positioning strip 411 to the preset welding position. Tighten the locking bolts to fix them, ensuring that the positioning plate 409 fits the bottom frame support point of the cabinet and the positioning strip 411 is aligned with the top welding reference line. Pull the lifting rod 407 of the positioning frame 405 upwards, compress the support spring to make the locking block of the locking seat 406 disengage from the locking groove of the sliding seat 401, and pull the positioning frame 405 outwards along the sliding groove. Using the bending block of the positioning frame 405 as a guide, the upper and lower frames of the electrical control cabinet are placed into the positioning area, so that the edge of the frame fits the reference surface of the positioning block 404. Release the lifting rod 407, the support spring pushes the locking seat 406 to reset, the locking block is embedded in the corresponding locking groove, and the positioning frame 405 is rigidly locked. The support spring on the outside of the positioning rod 402 pushes the positioning frame 405 toward the positioning block 404, and the elastic clamping force firmly clamps the frame to avoid deformation caused by rigid compression. If different positions of the frame or the side of the cabinet need to be welded, the drive unit inside the control body 1 is activated to drive the positioning body 2 to rotate, so that the workpiece is rotated to a suitable angle; when welding the bottom horizontal frame and the panel, the positioning plate 409 provides support and positions the welding point; when welding the top structure, the positioning strip 411 assists in positioning from above, and works with the positioning plate 409 to achieve synchronous upper and lower calibration, thereby improving the welding consistency. After welding is completed, pull up the lifting rod 407 to unlock the positioning bracket 405 and pull it outward to release the clamping on the frame; The control push cylinder 5 pushes the lifting plate 501 upward, at which time the lifting plate 501 assists in lifting the frame or cabinet, unloading the frame or cabinet; the adjustment of the push cylinder 5 lowers the lifting plate 501 to the lowest position, completing the welding of the frame or cabinet; Start the electric motor 301 to return the sliding seat 401 to its initial position; loosen the locking bolts of the support block 408 and the connecting rod 410, and reset the positioning plate 409 and the positioning strip 411 for future use.
