Description

Technical Field

[0001] This invention relates to a device for supporting the inner wall of a box, belonging to the field of welding fixtures. Background Technology

[0002] When welding external reinforcing ribs to a cabinet, the inner wall of the cabinet needs to be tightened and fixed to prevent welding deformation, especially for thin-walled aluminum alloy products. While tightening the inner wall, the parallelism of the cabinet's head and tail must also be ensured. Traditionally, mechanical internal bracing was used, tightening screws to hold the inner wall of the cabinet in place. This method is not only time-consuming but also significantly increases labor costs for mass production of cabinets, as clamping and disassembly are cumbersome and welding efficiency is low. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a box inner wall clamping device, which can automatically clamp, synchronize the beginning and end, and require less manual intervention, thereby improving the quality and welding efficiency of the external reinforcing ribs of the box product.

[0004] The present invention is achieved through the following technical solutions.

[0005] This invention provides a box inner wall support device, including a tooling base; one end of the tooling base is provided with a positioner, and the other end is provided with an electric bracket, with an inner support beam connected between the positioner and the electric bracket; one end of the inner support beam connected to the positioner is connected to the tooling base through the bracket, and a positioning block is provided between the inner support beam and the positioner; the inner support beam is provided with multiple support structures, including a miniature hydraulic cylinder and pulley on the upper side of the inner support beam and a miniature hydraulic cylinder and pulley on the right side, and bosses on the right and lower sides of the inner support beam; the extension rod of the miniature hydraulic cylinder is connected to a top plate, and the two ends of the top plate are respectively connected to the inner support beam through guide rods; guide rod mounting plates connected to the inner support beam are respectively provided between the miniature hydraulic cylinders installed in the same circumferential direction, and the guide rods are arranged obliquely symmetrically to offset the installation space of the miniature hydraulic cylinder on the other side.

[0006] There are at least three such bracing structures.

[0007] Of the two guide rods located on the upper side, one guide rod is connected to the inner support beam, and the other guide rod is connected to the guide rod mounting plate located on the right side; of the two guide rods located on the right side, one guide rod is connected to the inner support beam, and the other guide rod is connected to the guide rod mounting plate located on the upper side.

[0008] The height of the pulley is less than the maximum height of the extended rod of the miniature hydraulic cylinder, but greater than the minimum height of the retracted rod of the miniature hydraulic cylinder.

[0009] The bottom of the bracket is a screw structure, and the top of the bracket is symmetrically equipped with rolling bearings.

[0010] The electric bracket includes a fixed seat connected to the tooling base, a lifting rod connected to the inner support beam on the fixed seat, and multiple sets of bearings on the lifting rod.

[0011] The bracket is installed below the mounting flange of the positioner.

[0012] The screw structure is equipped with a nut.

[0013] The beneficial effects of this invention are as follows: throughout the process, the number of manual interventions is reduced, and the labor intensity of loading and unloading the box is also reduced. The automated internal support and flipping method greatly reduces the welding time of the external reinforcing ribs of the box. For the processing of large-scale box products, it provides a simple and efficient welding method. Attached Figure Description

[0019] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0020] like Figures 1-4The illustrated box inner wall support device includes a tooling base; one end of the tooling base is provided with a positioner 1, and the other end is provided with an electric bracket 7, with an inner support beam 4 connecting the positioner 1 and the electric bracket 7; one end of the inner support beam 4 connected to the positioner 1 is connected to the tooling base through a bracket 2, and a positioning block 5 is provided between the inner support beam 4 and the positioner 1; the inner support beam 4 is provided with multiple support structures, including a miniature hydraulic cylinder 403 disposed on the upper side of the inner support beam 4. The pulley 6 and the miniature hydraulic cylinder 403 on the right side, the pulley 6, and the inner support beam 4 are all provided with bosses 405 on the right and lower sides; the extension rod of the miniature hydraulic cylinder 403 is connected to the top plate 402, and the two ends of the top plate 402 are respectively connected to the inner support beam 4 through guide rods 401; between the miniature hydraulic cylinders 403 installed in the same circumferential direction, there are guide rod mounting plates 404 connected to the inner support beam 4, and the guide rods 401 are arranged obliquely and symmetrically to offset the installation space of the miniature hydraulic cylinder 403 on the other side.

[0021] Specifically, the miniature hydraulic cylinder 403 is installed at the welding position of the reinforcing rib.

[0022] There are at least three such bracing structures.

[0023] Of the two guide rods 401 located on the upper side, one guide rod 401 is connected to the inner support beam 4, and the other guide rod 401 is connected to the guide rod mounting plate 404 located on the right side; of the two guide rods 401 located on the right side, one guide rod 401 is connected to the inner support beam 4, and the other guide rod 401 is connected to the guide rod mounting plate 404 located on the upper side.

[0024] The height of the pulley 6 is less than the maximum height of the extension rod of the micro cylinder 403 when it is extended, and greater than the minimum height of the extension rod of the micro cylinder 403 when it is retracted, so as to load and deliver the box product into and out of the inner support beam 4.

[0025] The bottom of the bracket 2 is a screw structure, and the top of the bracket 2 is symmetrically equipped with rolling bearings to support and rotate the inner support beam 4.

[0026] The electric support bracket 7 includes a fixed base 702 connected to the tooling base, a lifting rod 701 connected to the inner support beam 4 on the fixed base 702, and multiple sets of bearings on the lifting rod 701 for lifting and flipping the inner support beam 4.

[0027] Furthermore, an electric bracket 7 is adopted to facilitate loading and unloading of the boxed products.

[0028] The bracket 2 is installed below the mounting flange of the positioner 1.

[0029] The screw structure is equipped with a nut 3, and the height of the bracket 2 can be adjusted by turning the nut 3.

[0030] Furthermore, positioning block 5 is used to secure the box product during installation.

[0031] Furthermore, after the boss 405 is pressurized by the micro hydraulic cylinder 403, the inner support beam 4 separates from the non-welded parts of the box product.

[0032] Specifically, when welding external reinforcing ribs is required, first control the lifting rod 701 to descend to a suitable position, then send the box product along the pulley 6 onto the inner support beam 4 until one end of the box product touches the positioning block 5, and then lift the lifting rod 701 to the lifting position; then start the oil pump to pressurize the micro cylinder 403, and the extension rod of the micro cylinder 403 drives the top plate 402 to move until the inner wall of the box is tightened to a certain height. During the tightening process, the micro cylinders 403 on the upper and right sides extend, so that the box product can adaptively complete the tightening of all four sides.

[0033] Specifically, after completing the welding of the external reinforcing ribs on one side, the positioner 1 can be rotated to other sides for welding. After all welding is completed, the oil pump is turned off and the pressure is released. The extension rod of the micro hydraulic cylinder 403 returns to the initial position, the lifting rod 701 is lowered, and the box product is pulled out from the inner support beam along the pulley 6.

[0034] In summary, this invention is well-suited for circumferential welding of external reinforcing ribs in enclosures. The micro hydraulic cylinder extends under pressure, causing the inner wall of the enclosure to self-adaptively tighten and fix, ensuring all weld seams are tightened into place simultaneously. The positioner and bracket make product flipping more convenient, and the electric bracket greatly facilitates the insertion and removal of the enclosure. This reduces the number of manual interventions and the workload of workers, while improving welding efficiency, making it particularly suitable for scenarios involving large-scale manual welding or automated robotic welding.
