This invention includes two opposing bases, wherein the two bases are detachably connected and the distance between them is adjustable, facilitating the clamping and fixing of side panels of different lengths. Each base has a horizontal portion and a vertical portion. A clamp is slidably mounted on the horizontal portion along its length direction, and this clamp can slide along the width direction of the horizontal portion. A clamp is also slidably mounted on the vertical portion along its vertical direction, and this clamp can slide along its horizontal direction. The positions of the four clamps can be adjusted according to different side panels, thus better clamping and fixing the side panels. This invention, through the arrangement of two bases and clamps, and the adjustable distance between the two bases, allows for adjustment of the distance between the two bases according to different lengths of side panels. The clamps then clamp and fix the side panels, enabling welding to pillars or window beams, etc.
[0003] However, the technology disclosed in the above patent requires manually tightening four drive bolts to fix the side panel during implementation, which results in low fixing efficiency. Therefore, it is necessary to propose a welding fixture for welding side panel columns to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a welding fixture for welding side panel columns, so as to solve the problem mentioned in the background art that when welding side panel columns, it is necessary to manually tighten four drive bolts to fix the side panel, resulting in low fixing efficiency.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a welding fixture for welding side columns, comprising a welding table, wherein the welding table has four sliding grooves arranged in a matrix evenly distributed inside, the sliding grooves simultaneously penetrating the upper and lower surfaces of the welding table, a sliding seat is slidably disposed inside the sliding groove, a clamping part is disposed on the top of the sliding seat, and an adjustment component is disposed between the sliding seat and the welding table. The adjustment assembly includes a hydraulic cylinder, which is fixedly installed in the middle of the bottom of the welding table. A lifting plate is fixedly installed at the telescopic end of the hydraulic cylinder. Four first hinge seats are fixedly installed on the side of the lifting plate. A second hinge seat is fixedly installed at the bottom of the sliding seat. A movable rod is rotatably installed between the corresponding second hinge seats and the first hinge seats. An auxiliary component is provided at the center of the top of the welding station.
[0006] Preferably, the vertical cross-section of the slide groove is cross-shaped, the vertical cross-section of the sliding seat is T-shaped, and the sliding seat and the slide groove are movably engaged.
[0007] Preferably, both ends of the top of the lifting plate are fixedly provided with sleeve rods, and a telescopic rod is slidably provided inside the sleeve rods. The upper end of the telescopic rod is fixedly connected to the lower surface of the welding table.
[0008] Preferably, the clamping part includes a mounting rod, which is fixedly connected to a mounting assembly and a sliding seat. A second clamping plate is fixedly disposed on the top of the mounting rod, and a first clamping plate is fixedly disposed on the side of the mounting rod. Rubber plates are fixedly disposed on the sides of both the first and second clamping plates.
[0009] Preferably, the mounting assembly includes a mounting groove, which is formed inside the sliding seat. The lower end of the mounting rod is movably inserted into the mounting groove, and a fixing bolt is threadedly connected between the sliding seat and the mounting rod.
[0010] Preferably, the auxiliary component includes a collection box, which is fixedly disposed in the middle of the top of the welding station, and a movable box is slidably disposed inside the collection box, and a through hole is provided on the upper surface of the collection box.
[0011] Preferably, support rods are fixedly installed at the four corners of the bottom of the welding table.
[0012] The technical effects and advantages of this utility model are as follows: 1. In use, the side panel is placed on the collection box, the hydraulic cylinder is activated, and the lifting plate is moved downward. Under the linkage of the four movable rods, the four sliding seats are moved towards the collection box inside the corresponding sliding grooves, which in turn moves the four clamping parts towards the collection box simultaneously. This causes the four first clamping plates to fix the side of the side panel, and the four second clamping plates to press down the top of the side panel, thus fixing the side panel on the collection box. After the welding of the side panel and the column is completed, the hydraulic cylinder is activated in reverse to loosen the side panel, which improves the fixing and unloading efficiency of the side panel and solves the problem that in the prior art, when welding the side panel column, four drive bolts need to be manually tightened to fix the side panel, resulting in low fixing efficiency. 2. When welding the side panels and columns, a certain amount of water is placed inside the movable box. The metal particles that splash during welding are refracted by the through holes, which slows down their rebound speed and makes it easier for the metal particles to pass through the through holes and be shot into the water for collection. This prevents the metal particles that splash during welding from messing up the work area and avoids the trouble of cleaning for workers. 3. When the shape of the side panel is different, the clamping part needs to be replaced to achieve the best fixing state. At this time, unscrew the fixing bolts to remove the clamping part from the sliding seat, replace it with a new clamping part and install it in reverse, which improves the flexibility and convenience of the device.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] This utility model provides, for example Figures 1-5 The welding fixture shown includes a welding table 1. Support rods 14 are fixedly installed at the four corners of the bottom of the welding table 1. The welding table 1 has four sliding grooves 2 arranged in a matrix. The sliding grooves 2 pass through the upper and lower surfaces of the welding table 1. A sliding seat 3 is slidably installed inside the sliding groove 2. A clamping part is provided on the top of the sliding seat 3. An adjustment component is provided between the sliding seat 3 and the welding table 1. An auxiliary component is provided in the middle of the top of the welding table 1.
[0017] The adjustment component includes a hydraulic cylinder 4, which is fixedly installed in the middle of the bottom of the welding table 1. A lifting plate 5 is fixedly installed at the telescopic end of the hydraulic cylinder 4. Four first hinge seats are fixedly installed on the side of the lifting plate 5. A second hinge seat is fixedly installed at the bottom of the sliding seat 3. A movable rod 6 is rotatably installed between the corresponding second hinge seats and the first hinge seats.
[0018] The clamping part includes a mounting rod 10, which is fixedly connected to the mounting assembly and the sliding seat 3. A second clamping plate 13 is fixedly provided on the top of the mounting rod 10, and a first clamping plate 12 is fixedly provided on the side of the mounting rod 10. Rubber plates are fixedly provided on the sides of both the first clamping plate 12 and the second clamping plate 13.
[0019] The auxiliary components include a collection box 15, which is fixedly installed in the middle of the top of the welding station 1. A movable box 17 is slidably installed inside the collection box 15, and a through hole 16 is opened on the upper surface of the collection box 15.
[0020] Specifically, in use, the side panel is placed on the collection box 15, the hydraulic cylinder 4 is activated, and the lifting plate 5 is moved downward. Under the linkage of the four movable rods 6, the four sliding seats 3 are moved towards the collection box 15 inside the corresponding sliding grooves 2, which in turn causes the four clamping parts to move synchronously towards the collection box 15. This results in the four first clamping plates 12 fixing the side of the side panel and the four second clamping plates 13 pressing down on the top of the side panel, thus fixing the side panel to the collection box 15. After the welding of the side panel and the column is completed, the hydraulic cylinder 4 is activated in the reverse direction to loosen the side panel, improving the fixing and unloading efficiency of the side panel. This solves the problem of low fixing efficiency in the prior art, where four drive bolts need to be manually tightened to fix the side panel when welding the side column.
[0021] In addition, when welding the side panels and columns, a certain amount of water is placed inside the movable box 17. The metal particles that splash during welding are refracted by the through hole 16, which slows down their rebound speed and makes it easier for the metal particles to pass through the through hole 16 and be shot into the water for collection. This prevents the metal particles that splash during welding from messing up the work area and avoids the trouble of cleaning for workers.
[0022] Furthermore, the vertical cross section of the slide groove 2 is cross-shaped, and the vertical cross section of the sliding seat 3 is T-shaped. The sliding seat 3 and the slide groove 2 are movably engaged. This arrangement allows the sliding seat 3 to slide stably within the slide groove 2.
[0023] Furthermore, sleeve rods 7 are fixedly installed at both ends of the top of the lifting plate 5. Telescopic rods 8 are slidably installed inside the sleeve rods 7. The upper end of the telescopic rods 8 is fixedly connected to the lower surface of the welding table 1. By setting the sleeve rods 7 and the telescopic rods 8, the vertical displacement trajectory of the lifting plate 5 is limited to ensure its stable displacement.
[0024] Furthermore, the mounting components include a mounting groove 9, which is located inside the sliding seat 3. The lower end of the mounting rod 10 is movably inserted into the mounting groove 9. A fixing bolt 11 is threaded between the sliding seat 3 and the mounting rod 10. When the shape of the side panel is different, the clamping part needs to be replaced to achieve the best fixing state. At this time, the fixing bolt 11 can be unscrewed to remove the clamping part from the sliding seat 3 and a new clamping part can be installed in reverse, which improves the flexibility and convenience of the device.
[0025] Working Principle: In use, the side panel is placed on the collection box 15. The hydraulic cylinder 4 is activated, causing the lifting plate 5 to move downwards. Under the linkage of the four movable rods 6, the four sliding seats 3 move towards the collection box 15 within their corresponding grooves 2. This, in turn, causes the four clamping parts to move synchronously towards the collection box 15, so that the four first clamping plates 12 fix the sides of the side panel, and the four second clamping plates 13 press down on the top of the side panel, thus fixing the side panel onto the collection box 15. The side panel is then welded to the column. Furthermore, during the welding of the side panel and the column, the movable box 17... A certain amount of water is placed inside. The metal particles that splash during welding are refracted by the through hole 16, which slows down their rebound speed and makes it easier for the metal particles to be ejected into the water after passing through the through hole 16 for collection. This prevents the metal particles from splashing during welding from messing up the work area, thus avoiding the trouble of cleaning for workers. After the welding of the side panel and the column is completed, the hydraulic cylinder 4 is started in reverse to loosen the side panel and perform the material unloading operation. When the shape of the side panel is different, the clamping part needs to be replaced to achieve the best fixing state. At this time, the fixing bolt 11 is unscrewed, and the clamping part can be removed from the sliding seat 3. A new clamping part can be installed in reverse.
[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
