Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, specifically a welding fixture that is easy to disassemble and replace. Background Technology

[0002] Sheet metal processing is a comprehensive cold working process for thin metal sheets, including shearing, punching / cutting / combined cutting, bending, welding, riveting, splicing, and forming (such as car bodies). Its significant characteristic is that the thickness of the same part is consistent. Welding is a very important part of sheet metal processing. However, traditional welding fixtures have multiple adjustment functions to accommodate welding sheet metal of different lengths, but they lack adjustment capabilities and cannot meet the dual needs of freeing and clamping.

[0003] Traditional welding fixtures require bolts or steel plates to be welded to a worktable, and clamps to hold the parts in place. This process is cumbersome, and disassembly after welding is also troublesome. Furthermore, the original welding equipment needs to be removed when welding different workpieces, which reduces the practicality of the welding fixture and affects processing efficiency. Therefore, we propose a welding fixture that is easy to disassemble and replace. Utility Model Content

[0004] The purpose of this invention is to provide a welding fixture that is easy to disassemble and replace, in order to solve the problem mentioned in the background art of reducing the practicality of welding fixtures and affecting their processing efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a welding fixture that is easy to disassemble and replace, comprising a workbench, a plug rod, and a mounting plate. The plug rod is located at the top of the workbench, and the mounting plate is located on one side of the plug rod. A folding groove is formed on the lower inner side of the plug rod. A mounting hole is formed at the bottom of the inner cavity of the folding groove. A lifting block is placed inside the mounting hole. A wedge-shaped hole is formed at the top of the lifting block. A wedge-shaped block is embedded in the wedge-shaped hole. Support blocks are fixedly connected to the left and right sides of the top of the wedge-shaped block. The support blocks are located in the inner cavity of the folding groove. A pull rod is rotatably connected to the top of the plug rod. The bottom end of the pull rod passes through the plug rod and the wedge-shaped block and extends into the wedge-shaped hole. The bottom end of the pull rod is screwed to the lifting block.

[0006] Preferably, the top of the workbench has a table hole, and the table holes are evenly distributed. The insertion rod is inserted into the inside of the table hole, and the bottom of the workbench is fixedly connected to the four corners of the bottom.

[0007] Preferably, a positioning ring is fixedly connected to the outer side wall of the insertion rod and located on the upper side of the workbench, and limit rings are fixedly connected to the upper and lower sides of the outer side wall of the insertion rod, with the limit rings located on the upper side of the positioning ring. A rotating sleeve is rotatably connected to the outer side wall of the insertion rod and located on the inner side of the two limit rings, and the mounting plate is fixedly connected to the outer side of the rotating sleeve.

[0008] Preferably, the mounting plate has a movable groove on its right side, a movable block is slidably connected to the inner cavity of the mounting plate, a mounting seat is provided on the right side of the mounting plate, a hidden hole is provided on the right side of the mounting seat, a fixing bolt is inserted into the hidden hole, and the end of the fixing bolt is screwed to the movable block.

[0009] Preferably, a pressure beam is fixedly connected to the bottom of the mounting base, and a hidden groove is opened at the bottom of the pressure beam.

[0010] Preferably, an adjusting bolt is screwed to the top of the pressure beam, the bottom end of the adjusting bolt passes through the pressure beam and extends into the inner cavity of the hidden groove, a pressure plate is rotatably connected to the bottom end of the adjusting bolt, and the pressure plate is located in the inner cavity of the hidden groove, and an anti-slip pad is adhered to the bottom of the pressure plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This easily disassembled and replaceable welding fixture works by inserting a rod into the table hole and positioning it with a positioning ring. Simultaneously, rotating the pull rod drives the lifting block to rise. As the lifting block rises, it squeezes the wedge block through the wedge hole, causing the wedge block to rise. The wedge block squeezes the support block, which extends from inside the folding groove and contacts the bottom of the worktable, so that the rod is firmly locked into the table hole. This makes the installation and operation of the welding fixture more convenient and also facilitates its disassembly later.

[0013] 2. This easily disassembled and replaceable welding fixture uses a limiting ring on the insertion rod to limit the rotation of the sleeve, allowing the mounting plate to be adjusted in any direction. The mounting base is connected to the moving block via fixing bolts. The moving block allows the pressure beam at the bottom of the mounting base to be moved up and down. Simultaneously, rotating the adjusting bolts at different positions causes the pressure plate to descend from the hidden groove, which can press down and fix irregularly shaped workpieces, thereby improving the practicality of the welding fixture and increasing its processing efficiency.

[0024] Example: Figures 1-6 As shown, this utility model provides a welding fixture that is easy to disassemble and replace, which makes the installation and operation of the welding fixture more convenient and also facilitates its disassembly later, thereby improving the practicality of the welding fixture and increasing its processing efficiency. It includes a workbench 100, a plug rod 200 and a mounting plate 300.

[0025] Please see Figure 1-2 The top of the workbench 100 has a table hole 110, and the table holes 110 are evenly distributed. The insertion rod 200 is inserted into the inside of the table hole 110. The bottom four corners of the workbench 100 are fixedly connected to the support legs 120.

[0026] Please see Figure 1-5The insert rod 200 has a folding groove 210 on its lower inner side. A mounting hole 211 is located at the bottom of the inner cavity of the folding groove 210. A lifting block 220 is placed inside the mounting hole 211. A wedge-shaped hole 221 is located at the top of the lifting block 220. A wedge-shaped block 222 is embedded in the wedge-shaped hole 221. Support blocks 223 are fixedly connected to the left and right sides of the top of the wedge-shaped block 222. The support blocks 223 are located within the inner cavity of the folding groove 210. A pull rod 230 is rotatably connected to the top of the insert rod 200. The bottom end of the pull rod 230 passes through the insert rod 200 and the wedge-shaped block 222 and extends into the wedge-shaped hole 221. The bottom end of the pull rod 230 is screwed to the lifting block 220. A positioning ring 240 is fixedly connected to the outer wall of the insert rod 200, located on the upper side of the worktable 100. The upper and lower sides of the outer wall of the insert rod 200 are fixed... A limiting ring 250 is connected and is located above the positioning ring 240. A rotating sleeve 260 is rotatably connected to the outer wall of the insertion rod 200 and located inside the two limiting rings 250. The mounting plate 300 is fixedly connected to the outer side of the rotating sleeve 260. The insertion rod 200 is located at the top of the worktable 100. The insertion rod 200 is inserted into the table hole 110 and positioned by the positioning ring 240. At the same time, the pull rod 230 is rotated to drive the lifting block 220 to lift. While the lifting block 220 is lifted, it squeezes the wedge block 222 through the wedge hole 221, causing the wedge block 222 to rise. The wedge block 222 squeezes the support block 223, which extends from the inside of the folding groove 210 and contacts the bottom of the worktable 100, so that the insertion rod 200 is firmly locked in the table hole 110.

[0027] In summary, this makes the installation and operation of welding fixtures more convenient, and also facilitates their later dismantling.

[0028] Please refer to it again. Figure 1-6The mounting plate 300 has a movable groove 310 on its right side. A movable block 311 is slidably connected to the inner cavity of the mounting plate 300. A mounting base 320 is located on the right side of the mounting plate 300. A hidden hole 321 is opened on the right side of the mounting base 320. A fixing bolt 322 is inserted into the hidden hole 321. The end of the fixing bolt 322 is screwed to the movable block 311. A pressure beam 330 is fixedly connected to the bottom of the mounting base 320. A hidden groove 331 is opened at the bottom of the pressure beam 330. An adjusting bolt 332 is screwed to the top of the pressure beam 330. The bottom end of the adjusting bolt 332 passes through the pressure beam 330 and extends into the inner cavity of the hidden groove 331. The bottom end of the adjusting bolt 332 is rotatably connected to... The pressure plate 333 is located in the inner cavity of the hidden groove 331. The bottom of the pressure plate 333 is bonded with an anti-slip pad 334. The mounting plate 300 is located on one side of the insertion rod 200. The rotating sleeve 260 is limited by the limiting ring 250 set on the insertion rod 200, so that the mounting plate 300 can be adjusted in any direction. The mounting base 320 is connected to the moving block 311 by the fixing bolt 322. The pressure beam 330 at the bottom of the mounting base 320 can be moved up and down by the moving block 311. At the same time, rotating the adjusting bolt 332 at different positions drives the pressure plate 333 to descend from the hidden groove 331, which can press down and fix the irregular workpiece.

[0029] In summary, this approach can improve the practicality of welding fixtures and increase their processing efficiency.

[0030] In practical use, when welding sheet metal workpieces, those skilled in the art place the workpiece on the workbench 100, select a suitable table hole 110 according to the workpiece's position, install the insert rod 200, insert the insert rod 200 into the table hole 110, and position it using the positioning ring 240. Simultaneously, rotating the pull rod 230 drives the lifting block 220 to rise. As the lifting block 220 rises, it presses the wedge block 222 through the wedge hole 221, causing the wedge block 222 to rise. The wedge block 222 also presses the support block 223 out of the folding groove 210. The part extends out to contact the bottom of the workbench 100, so that the insertion rod 200 is firmly locked in the table hole 110. Then, the pressure beam 330 is rotated so that the limiting ring 250 limits the rotation of the rotating sleeve 260. The mounting plate 300 can be adjusted in any direction. The moving block 311 can move the pressure beam 330 at the bottom of the mounting base 320 up and down. At the same time, rotating the adjusting bolts 332 at different positions drives the pressure plate 333 to descend from the hidden groove 331, which can press down and fix irregular workpieces, so that the welding work of sheet metal workpieces can be carried out.
