Technical Field
[0001] This utility model relates to the field of metal welding technology, specifically to a metal welding fixture. Background Technology
[0002] Traditional welding fixtures often use simple clamps or mechanical devices to hold and fix metal parts. This fixing method is prone to displacement of metal parts due to vibration or thermal stress during the welding process, which affects the welding quality.
[0003] In existing technologies, before welding complex products, each part needs to be manually positioned sequentially, and then fixed sequentially by a welding machine to facilitate the overall welding work. However, in actual use, since the product is composed of multiple large metal parts, manually aligning the parts before welding can easily cause deformation during the welding process, resulting in dimensions that do not meet requirements. Therefore, it is necessary to improve the metal part welding fixture. Utility Model Content
[0004] The purpose of this utility model is to provide a welding fixture for metal parts to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a metal welding fixture, including a workbench, a support positioning plate fixedly connected to the top of the workbench, a connecting frame fixedly connected to the bottom of the workbench, a positioning and fixing mechanism provided on the top of the workbench, a pressing mechanism provided on the top of the workbench, and a product provided on the top of the positioning and fixing mechanism;
[0006] The positioning and fixing mechanism includes a positioning component and a fixing component, wherein the fixing component is disposed on top of the positioning component;
[0007] The positioning component includes a fixing plate, which is fixedly connected to the top of the workbench. Limiting plates are fixedly connected to the front and rear sides of the fixing plate. A first support plate is fixedly connected to the top of the limiting plate. A second support plate is fixedly connected to the top of the first support plate. A fixing column is fixedly connected to the top of the workbench, which facilitates the positioning of the product's metal parts and thus facilitates welding.
[0008] Preferably, a groove is provided at the position corresponding to the fixed plate on the workbench, and the fixed plate is fixedly connected in the groove to facilitate limiting the position of the fixed plate.
[0009] Preferably, the fixing component includes a clamping plate, which is fixedly connected to the top of the fixing plate and the fixing post respectively. A connecting sleeve is fixedly connected to the top of the clamping plate, and a handle is rotatably connected to the top of the connecting sleeve. A push rod is rotatably connected to the end of the handle away from the connecting sleeve, and a locking rod is rotatably connected to the end of the push rod away from the handle. A threaded post is internally threaded to the locking rod, which facilitates fixing the metal parts of the product and thus facilitates welding.
[0010] Preferably, a groove is provided at the position corresponding to the connecting sleeve and the first locking rod, and the first locking rod is slidably connected in the groove, which facilitates pushing the first locking rod to move.
[0011] Preferably, the connecting sleeve has a hole at the position corresponding to the handle, and the handle is rotatably connected in the hole, which facilitates the rotation of the handle.
[0012] Preferably, the clamping mechanism includes a positioning column, which is fixedly connected to the top of the workbench. A connecting plate is fixedly connected to the top of the positioning column, and a connecting block is rotatably connected to the top of the connecting plate. A handle two is rotatably connected to the end of the connecting block away from the connecting plate, and a pressure rod is rotatably connected to the end of the handle two away from the connecting block. A threaded post two is threaded inside the pressure rod to facilitate pressing the metal part downward, thereby improving the fixing effect.
[0013] Preferably, the connecting plate has a hole at the corresponding position of the pressure rod, and the pressure rod is rotatably connected in the hole, which facilitates pushing the pressure rod downward.
[0014] Compared with the prior art, this utility model provides a welding fixture for metal parts, which has the following advantages:
[0015] 1. This metal welding fixture, through a positioning and fixing mechanism, places a corresponding portion of the product's metal parts on support plate one and support plate two respectively. Then, the metal parts are positioned by the limiting plates on the front and rear sides. After positioning, by manually pushing handle one, the locking rod one drives the threaded column one to gradually approach the outer wall of the product, thereby pushing the metal part forward and fixing the metal part on this side to the metal part on the support frame one. This allows the device to achieve the positioning and fixing of the corresponding metal parts, preventing displacement during subsequent welding and ensuring dimensional requirements are met.
[0016] 2. This metal welding fixture, through the set clamping mechanism, allows manual downward pressing of handle two. As handle two moves downward, it simultaneously pushes the pressure rod to rotate around the connection point of the connecting plate, thereby causing it to move threaded post two downward. This causes threaded post two to contact the top of the corresponding metal part, thus fixing the corresponding metal part between the support positioning plate and threaded post two. This prevents the corresponding metal part from shaking during the welding process, thereby preventing it from affecting the subsequent welding effect. Attached Figure Description

Please refer to [link / reference needed]. Figure 1-5 This utility model provides a technical solution: a metal welding fixture, including a workbench 1, a support positioning plate 2 fixedly connected to the top of the workbench 1, a connecting frame 3 fixedly connected to the bottom of the workbench 1, a positioning and fixing mechanism 4 provided on the top of the workbench 1, a pressing mechanism 6 provided on the top of the workbench 1, and a product 5 provided on the top of the positioning and fixing mechanism 4.
[0028] The positioning and fixing mechanism 4 includes a positioning component 41 and a fixing component 42, with the fixing component 42 disposed on top of the positioning component 41;
[0029] The positioning component 41 includes a fixing plate 411, which is fixedly connected to the top of the workbench 1. Limiting plates 412 are fixedly connected to the front and rear sides of the fixing plate 411. A support plate 413 is fixedly connected to the top of the limiting plate 412. A support plate 414 is fixedly connected to the top of the support plate 413. A fixing column 415 is fixedly connected to the top of the workbench 1, which facilitates the positioning of the metal parts of the product 5 and thus facilitates welding.
[0030] Furthermore, a groove is provided at the corresponding position of the workbench 1 and the fixed plate 411, and the fixed plate 411 is fixedly connected in the groove, which facilitates limiting the position of the fixed plate 411.
[0031] Furthermore, the fixing component 42 includes a clamping plate 421, which is fixedly connected to the top of the fixing plate 411 and the fixing post 415 respectively. A connecting sleeve 422 is fixedly connected to the top of the clamping plate 421. A handle 423 is rotatably connected to the top of the connecting sleeve 422. A push rod 424 is rotatably connected to the end of the handle 423 away from the connecting sleeve 422. A locking rod 425 is rotatably connected to the end of the push rod 424 away from the handle 423. A threaded post 426 is threadedly connected inside the locking rod 425, which facilitates fixing the metal parts of the product 5 and thus facilitates welding.
[0032] Furthermore, a groove is provided at the corresponding position of the connecting sleeve 422 and the locking rod 425, and the locking rod 425 is slidably connected in the groove, which facilitates the movement of the locking rod 425.
[0033] Furthermore, the connecting sleeve 422 has a hole at the corresponding position of the handle 423, and the handle 423 is rotatably connected in the hole, making it convenient for the handle 423 to rotate.
[0034] Example 2:
[0035] Based on the existing technology's need to clamp various metal parts, please refer to... Figure 5 Furthermore, in conjunction with Embodiment 1, the clamping mechanism 6 includes a positioning post 61, which is fixedly connected to the top of the workbench 1. A connecting plate 62 is fixedly connected to the top of the positioning post 61. A connecting block 63 is rotatably connected to the top of the connecting plate 62. A handle 64 is rotatably connected to the end of the connecting block 63 away from the connecting plate 62. A pressure rod 65 is rotatably connected to the end of the handle 64 away from the connecting block 63. A threaded post 66 is threaded inside the pressure rod 65 to facilitate downward clamping of the metal parts, thereby improving the fixing effect.
[0036] Furthermore, the connecting plate 62 has holes at the corresponding positions of the pressure rod 65, and the pressure rod 65 is rotatably connected in the holes, which facilitates pushing the pressure rod 65 downward.
[0037] In actual operation, when the device is in use, firstly, before welding product 5, when it is necessary to fix each metal part, the positioning and fixing mechanism 4 is used to place the corresponding metal parts of product 5 on support plate 1 413 and support plate 2 414 respectively. Then, the metal parts are positioned by aligning them with the limiting plates 412 on the front and rear sides. After positioning is completed, the handle 1 423 is manually pushed. During the movement of the handle 423, the push rod 424 is simultaneously pushed to move. During the movement of the push rod 424, the locking rod 425 is simultaneously moved, so that the locking rod 425 drives the threaded column 426 to gradually approach the outer wall of product 5, thereby pushing the metal part forward and aligning the metal part on this side with the support frame. The metal parts on the support frame are fixed and positioned so that the device can fix the corresponding metal parts. Then, the corresponding metal parts are placed on the workbench 1 and the corresponding support positioning plate 2 in turn. The metal parts are then aligned and positioned in turn. Then, the handle 64 is manually pressed down by the clamping mechanism 6. As the handle 64 moves down, it pushes the pressure rod 65 to rotate around the connection point of the connecting plate 62. This causes the threaded column 66 to move down, so that the threaded column 66 contacts the top of the corresponding metal part, thereby fixing the corresponding metal part between the support positioning plate 2 and the threaded column 66. This prevents the corresponding metal part from shaking during the welding process.
