Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to a welding fixture for welding based on machining. Background Technology

[0002] In the field of machining, welding is one of the core processes for connecting metal components. Welding fixtures are key equipment for ensuring welding accuracy and work efficiency, and their performance directly affects the welding quality and production stability of the workpiece.

[0003] In the prior art, such as Chinese Patent Publication No. CN219131291U, a welding fixture for machining is disclosed, including a worktable. A work plate is fixedly installed at the top of the worktable, and hydraulic telescopic columns are fixedly installed on both sides of the top of the work plate. Each of the two hydraulic telescopic columns has a groove, and two electric sliders are slidably installed in each of the two grooves. A clamp is fixedly installed in each of the two electric sliders on both sides, and a first slot is opened on the inner side of each of the two clamps on both sides. In this utility model, when using the device, the workpiece to be processed is simply placed on the work plate, and the hydraulic telescopic columns are controlled to push the clamps inward through the control panel. At the same time, the electric sliders slide in the grooves, controlling the clamps to move inward and clamping the workpiece. This arrangement allows the workpiece to be clamped in both the X and Y directions, effectively ensuring that the workpiece does not shake during the welding process.

[0004] Although the above technical solution has the above technical advantages, its disadvantages are: the solution relies on hydraulic and electric drive, which is not only complex in structure and high in cost, but also requires operation of the control panel during adjustment, which lacks convenience. In addition, the hydraulic telescopic column and clamp are fixed installation structures, which can only be used for single or small-sized workpieces, resulting in poor flexibility and a small range of applicability. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a welding fixture for machining and welding, which solves the problems of poor flexibility and limited adaptability of existing fixtures.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a welding fixture for machining welding, including a worktable, a welding machine bracket fixedly connected to the outside of the worktable, and a limiting slide, the limiting slide being fixedly installed on the top of the worktable, a positioning component being slidably connected to the top of the limiting slide, and the welding machine bracket installed on the outside of the worktable being used to fix the welding machine used for welding.

[0007] The positioning assembly includes a sliding seat, a lead screw rotatably connected to the inner wall of the sliding seat, knobs fixedly connected to both ends of the lead screw, a slider threadedly connected to the outer wall of the lead screw, clamping blocks fixedly connected to both sides of the slider, a rotating frame rotatably connected to the top of the sliding seat, a sliding plate slidably connected to the outer wall of the rotating frame, a tension spring fixedly connected to the bottom of the sliding plate, and limit rods fixedly connected to the bottom of both sides of the sliding plate. The bottom of the sliding seat is slidably connected to the inner side of the limit slide, and the outer side of the slider is slidably connected to the inner wall of the sliding seat. When the knob drives the lead screw to rotate, it drives the slider to slide along the inner wall of the sliding seat. When the slider slides, it drives the clamping blocks to move synchronously.

[0008] Preferably, the limiting slide is inserted into the bottom end of the limiting rod through a limiting hole, and the limiting hole is opened in the wall of the limiting slide. Multiple limiting holes are linearly arranged on the limiting slide to meet the fixing requirements of the positioning component at different positions.

[0009] Preferably, the outer wall of the limiting rod is slidably connected to both sides of the sliding seat, and the bottom end of the tension spring is fixedly connected to the top of the sliding seat through the spring seat. When the sliding plate is lifted upward, the limiting rod slides upward, and the tension spring is compressed by force.

[0010] Preferably, an adjusting rod is slidably connected to the inner side of the rotating frame, and a threaded rod is threadedly connected to the inner wall of the adjusting rod. The threaded rod is threadedly engaged with the inner wall of the adjusting rod, and the threaded rod can move up and down along the inner wall of the adjusting rod.

[0011] Preferably, a pressure block is rotatably connected to the bottom end of the threaded rod, and a rocker arm is slidably connected to the top end of the threaded rod. The rocker arm can slide along the top end of the threaded rod, which can easily change the torque when rotating the threaded rod, making it easier for the operator to fix the workpiece, and then the welding operation can be completed.

[0012] The beneficial effects of this utility model are as follows:

[0013] (i) The fixture is equipped with positioning components. Multiple limiting holes are linearly arranged on the limiting slide to meet the fixing requirements of the positioning components at different positions. Then, the operator can turn the knobs at both ends of the lead screw to make the slider slide, so that the clamping block can gradually approach the workpiece to be welded until it is in close contact with the surface of the workpiece. Thus, multiple positioning components can be used to cooperate with each other to achieve clamping and fixing of different workpieces in the horizontal direction, preventing horizontal displacement of the workpiece during the welding process.

[0014] (II) This fixture, through the cooperation of a rotating frame and an adjusting rod, can move the pressure block directly above the workpiece to be clamped. Rotating the rocker arm causes the threaded rod to move the pressure block downwards along the inner wall of the adjusting rod, providing vertical pressure to the workpiece. This clamps the two workpieces together, enhancing their stability during welding. The rocker arm can slide along the top of the threaded rod, allowing for easy adjustment of the torque when rotating the threaded rod, making it easier for the operator to fix the workpiece. The welding operation can then be completed. Attached Figure Description

[0020] 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.

[0021] Example: Please refer to Figure 1-4 This utility model provides a technical solution: a welding fixture for machining welding, including a worktable 1, a welding machine bracket 2 fixedly connected to the outside of the worktable 1, and a limiting slide 3, the limiting slide 3 being fixedly installed on the top of the worktable 1, and a positioning component 5 being slidably connected to the top of the limiting slide 3. The welding machine bracket 2 installed on the outside of the worktable 1 is used to fix the welding machine used for welding. When it is necessary to fix the workpiece to be welded, the operator can push two or more positioning components 5 to slide along the surface of the limiting slide 3 according to the size of the workpiece and the welding position requirements, and move them to both sides of the workpiece.

[0022] The positioning assembly 5 includes a sliding seat 51, a lead screw 52 rotatably connected to the inner wall of the sliding seat 51, knobs 53 fixedly connected to both ends of the lead screw 52, ​​a slider 54 threadedly connected to the outer wall of the lead screw 52, ​​clamping blocks 55 fixedly connected to both sides of the slider 54, a rotating frame 56 rotatably connected to the top of the sliding seat 51, a sliding plate 57 slidably connected to the outer wall of the rotating frame 56, a tension spring 58 fixedly connected to the bottom of the sliding plate 57, and limit rods 59 fixedly connected to the bottom of both sides of the sliding plate 57. The bottom of the sliding seat 51 is slidably connected to the inner side of the limit slide 3, the outer side of the slider 54 is slidably connected to the inner wall of the sliding seat 51, and the limit slide 3 is connected to the limit rods through the limit hole 4. The bottom end of the 59 is inserted, and the limiting hole 4 is opened in the wall of the limiting slide 3. The outer wall of the limiting rod 59 is slidably connected to both sides of the sliding seat 51. The bottom end of the tension spring 58 is fixedly connected to the top of the sliding seat 51 through the spring seat. When moving the sliding seat 51, the sliding plate 57 needs to be lifted up first, so that the limiting rod 59 slides up. At this time, the tension spring 58 is compressed. After the sliding seat 51 is moved to the designated position, the sliding plate 57 is released. At this time, the tension spring 58 drives the limiting rod 59 to reset, so that the bottom end of the limiting rod 59 is inserted into the limiting hole 4. There are multiple limiting holes 4 arranged linearly on the limiting slide 3, which can meet the fixing requirements of the positioning component 5 at different positions.

[0023] The operator then rotates the knobs 53 at both ends of the lead screw 52. When the knobs 53 rotate the lead screw 52, ​​they will drive the slider 54 to slide along the inner wall of the sliding seat 51. When the slider 54 slides, it will drive the clamping block 55 to move synchronously. When the slider 54 slides, the clamping block 55 can gradually approach the workpiece to be welded until it is in close contact with the surface of the workpiece. In this way, multiple positioning components 5 can be used to cooperate with each other to achieve horizontal clamping and fixing of different workpieces, preventing horizontal displacement of the workpiece during the welding process.

[0024] An adjusting rod 60 is slidably connected to the inner side of the rotating frame 56. A threaded rod 61 is threadedly connected to the inner wall of the adjusting rod 60. A pressure block 62 is rotatably connected to the bottom end of the threaded rod 61, and a rocker arm 63 is slidably connected to the top end of the threaded rod 61. If it is necessary to weld other workpieces on top of the fixed workpiece, the rotating frame 56 can be rotated and adjusted to the preset position of the workpiece. Then, push the adjusting rod 60 to slide along the inner side of the rotating frame 56 until the pressure block 62 is moved directly above the workpiece that needs to be pressed, ensuring that the pressure block 62 can accurately act on the target pressing point of the workpiece. Rotate the rocker arm 63, and the rocker arm 63 drives the threaded rod 61 to rotate. Since the threaded rod 61 is threadedly engaged with the inner wall of the adjusting rod 60, the threaded rod 61 will move downward along the inner wall of the adjusting rod 60. At this time, the pressure block 62 moves downward synchronously with the threaded rod 61 until the pressure block 62 is in close contact with the top of the workpiece, providing vertical pressure to the workpiece, thereby pressing the two workpieces together and enhancing the stability of the workpiece during the welding process. The rocker arm 63 can slide along the top of the threaded rod 61, which can easily change the torque when rotating the threaded rod 61, making it easier for the operator to fix the workpiece. Then the welding operation can be completed.

[0025] Working principle: When in use, the welding machine bracket 2 installed on the outside of the workbench 1 is used to fix the welding machine. When it is necessary to fix the workpiece to be welded, the operator can push two or more positioning components 5 to slide along the surface of the limiting slide table 3 according to the size of the workpiece and the welding position requirements, and move it to both sides of the workpiece.

[0026] When moving the sliding seat 51, the sliding plate 57 must be lifted upward first, so that the limiting rod 59 slides upward. At this time, the tension spring 58 is compressed. After the sliding seat 51 is moved to the designated position, the sliding plate 57 is released. At this time, the tension spring 58 drives the limiting rod 59 to reset, so that the bottom end of the limiting rod 59 is inserted into the limiting hole 4. There are multiple limiting holes 4 arranged linearly on the limiting slide 3, which can meet the fixing requirements of the positioning component 5 at different positions.

[0027] The operator then rotates the knobs 53 at both ends of the lead screw 52. When the knobs 53 rotate the lead screw 52, ​​they will drive the slider 54 to slide along the inner wall of the sliding seat 51. When the slider 54 slides, it will drive the clamping block 55 to move synchronously. When the slider 54 slides, the clamping block 55 can gradually approach the workpiece to be welded until it is in close contact with the surface of the workpiece. In this way, multiple positioning components 5 can be used to cooperate with each other to achieve horizontal clamping and fixing of different workpieces, preventing horizontal displacement of the workpiece during the welding process.

[0028] If it is necessary to weld other workpieces on top of the fixed workpiece, the rotating frame 56 can be rotated and adjusted to the preset position of the workpiece. Then, push the adjusting rod 60 to slide along the inner side of the rotating frame 56 until the pressure block 62 is moved directly above the workpiece to be pressed, ensuring that the pressure block 62 can accurately act on the target pressing point of the workpiece. Rotate the rocker arm 63, which drives the threaded rod 61 to rotate. Since the threaded rod 61 is threaded with the inner wall of the adjusting rod 60, the threaded rod 61 will move downward along the inner wall of the adjusting rod 60. At this time, the pressure block 62 moves downward synchronously with the threaded rod 61 until the pressure block 62 is in close contact with the top of the workpiece, providing vertical pressure to the workpiece. This can press the two workpieces together, which can enhance the stability of the workpiece during the welding process. The rocker arm 63 can slide along the top of the threaded rod 61, which can easily change the torque when rotating the threaded rod 61, making it easier for the operator to fix the workpiece. Then the welding operation can be completed.
