Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, and in particular to a welding fixture that can fix different shapes. Background Technology

[0002] Positioning is a crucial step in the welding process of workpieces, and fixtures are generally used to fix the position of the workpieces.

[0003] Most existing welding fixtures can only fix workpieces of one shape, which is not very versatile. When welding workpieces of different shapes, different fixtures are required to fix them, which increases the welding cost. Utility Model Content

[0004] This invention provides a welding fixture that can fix different shapes, solving the technical problem of poor applicability of existing welding fixtures.

[0005] To achieve this technical objective, the present invention adopts the following solution: a welding fixture that can fix different shapes, including a support frame, a sliding block, a connecting block and a clamping assembly;

[0006] The support frame includes a horizontal plate and a vertical plate. The horizontal plate has a first slide rail extending along its length. The vertical plate is fixedly installed at one end of the horizontal plate and has a second slide rail that is spliced ​​with the first slide rail.

[0007] Two sliding blocks are respectively slidably mounted on the first slide rail and the second slide rail;

[0008] Both ends of the connecting block are rotatably connected to the sliding block;

[0009] The clamping assembly is mounted on the connecting block and is used to clamp the workpiece to be welded.

[0010] Furthermore, the sliding block is connected to the vertical plate for limiting;

[0011] The sliding block has a through hole, and the vertical plate has multiple insertion holes extending in the same direction as the second slide rail;

[0012] The insertion rod is inserted into the through hole and the insertion hole. One end of the insertion rod is fixed with a limiting ring, and the limiting ring abuts against the sliding block.

[0013] Furthermore, a horizontally extending through groove is provided in the middle of the connecting block, and two symmetrically arranged arc-shaped grooves are provided on the top surface of the connecting block, with the arc-shaped grooves bending towards the middle of the connecting block.

[0014] Furthermore, the clamping assembly includes a base plate, a pivot, a screw, an anti-slip pad, a push rod, and an upper clamping plate;

[0015] The rotating shaft is fixedly mounted on the top surface of the connecting block;

[0016] One end of the base plate is rotatably connected to the rotating shaft, and a slider is provided at the bottom of the base plate. The slider is slidably inserted into the arc-shaped groove.

[0017] The upper clamping plates are spaced above the base plate, and are rotatably connected to the rotating shaft.

[0018] The screw and the upper clamping plate are threaded together. The smooth lower part of the screw is rotatably connected to the base plate. The lower part of the screw can slide through the top surface of the connecting block and extend into the through groove. An abutment plate is fixed at the bottom of the screw.

[0019] An anti-slip pad is placed between the connecting block and the abutment plate;

[0020] The bottom of the push rod and the connecting block are threaded together. One end of the connecting block, which is located in the through groove, is fixed with a pressure plate, which abuts against the abutment plate.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. The sliding block in the welding fixture that can fix different shapes disclosed in this utility model can slide on the first slide rail and the second slide rail, thereby adjusting the positional relationship between the two sliding blocks. Since the connecting block and the two sliding blocks are rotatably connected, the sliding of the sliding block can change the angle of the connecting block, causing the connecting block to flip, thereby driving the clamping component on the connecting block to flip, so that the clamping component can hold workpieces of different angles and shapes.

[0023] 2. During use, the clamping assembly clamps the workpiece between the upper clamping plate and the bottom plate. The bottom plate and the connecting block are connected by a rotating shaft, which allows the bottom plate and the upper clamping plate to rotate to adjust to the optimal position when fixing the workpiece, thereby matching workpieces of different shapes.

[0029] To fully understand the purpose, features and effects of this utility model, the following specific embodiments will be used to describe this utility model in detail, but this utility model is not limited thereto.

[0030] like Figures 1 to 3 As shown, the present invention provides a welding fixture capable of fixing different shapes, including a support frame 1, a sliding block 2, a connecting block 3, and a clamping assembly 4. The support frame 1 includes a horizontal plate 11 and a vertical plate 12. The horizontal plate 11 has a first slide rail 111 extending along its length direction. The vertical plate 12 is fixedly disposed at one end of the horizontal plate 11 and has a second slide rail 121 spliced ​​with the first slide rail 111.

[0031] Two sliding blocks 2 are respectively slidably mounted on the first slide rail 111 and the second slide rail 121. The sliding blocks 2 are limitedly connected to the vertical plate 12. In one embodiment, the sliding blocks 2 are provided with through holes 21, and the vertical plate 12 is provided with multiple insertion holes 122 extending in the same direction as the second slide rail 121. The insertion rod 5 is inserted into the through holes 21 and the insertion holes 122, and a limiting ring 51 is fixedly provided at one end of the insertion rod 5. The limiting ring 51 abuts against the sliding blocks 2.

[0032] Both ends of the connecting block 3 are rotatably connected to the sliding block 2. The working principle of the connecting block 3 and the sliding block 2 is as follows: when the sliding block 2 on the vertical plate 12 is pulled up or down, the connecting block 3 rotates accordingly. At the same time, the connecting block 3 drives the sliding block 2 on the horizontal plate 11 to slide. When the connecting block 3 is adjusted to a suitable angle, the insertion rod 5 is inserted into the insertion hole 122 and the through hole 21, thereby restricting the sliding block 2 on the vertical plate 12 from continuing to slide, thus fixing the position of the connecting block 3.

[0033] The clamping assembly 4 is mounted on the connecting block 3 and is used to clamp the workpiece to be welded. In one embodiment, the connecting block 3 has a transversely extending through groove 31 in its center, and two symmetrically arranged arc-shaped grooves 32 on its top surface, the arc-shaped grooves 32 curving towards the center of the connecting block 3. The clamping assembly 4 includes a base plate 41, a rotating shaft 42, a screw 43, an anti-slip pad 44, a top rod 45, and an upper clamping plate 46. The rotating shaft 42 is fixedly mounted on the top surface of the connecting block 3. One end of the base plate 41 is rotatably connected to the rotating shaft 42, and a slider is provided at the bottom of the base plate 41, which is slidably inserted into the arc-shaped groove 32. An upper clamping plate 46 is spaced above the base plate 41. The upper clamping plate 46 and the rotating shaft 42 are rotatably connected. A screw 43 is threadedly connected to the upper clamping plate 46. The smooth lower part of the screw 43 is rotatably connected to the base plate 41. The lower part of the screw 43 slidably passes through the top surface of the connecting block 3 and extends into the through groove 31. The screw 43 can slide up and down within the connecting block 3. An abutment plate 431 is fixedly provided at the bottom of the screw 43. An anti-slip pad 44 is placed between the connecting block 3 and the abutment plate 431. A top rod 45 is threadedly connected to the bottom of the connecting block 3. A pressure plate 451 is fixedly provided at one end of the connecting block 3 located in the through groove 31. The pressure plate 451 and the abutment plate 431 abut against each other.

[0034] by Figure 1 Let's take the clamping component 4 as an example to illustrate its working principle. Figure 1 The two clamping components 4 are referred to as the upper clamping component 4 and the lower clamping component 4 according to their positional relationship. First, adjust the upper clamping assembly 4. First, rotate the top rod 45 to move the pressure plate 451 away from the abutment plate 431. Then, fix the bottom plate 41 and the two sides of the upper clamping plate 46 by hand or tool. Then, place one end of the workpiece to be welded between the bottom plate 41 and the upper clamping plate 46. Then, rotate the screw 43 to move the upper clamping plate 46 downward, thereby firmly clamping the workpiece between the upper clamping plate 46 and the bottom plate 41. Then, rotate the upper clamping plate 46 and the bottom plate 41 so that they can rotate around the pivot 42 to adjust the angle of the workpiece. After adjusting to a suitable angle (so that the other end of the workpiece can be clamped in the lower clamping assembly 4), rotate the top rod 45 again to make the pressure plate 451 press tightly against the abutment plate 431, so that the abutment plate 431 is firmly attached to the anti-slip pad 44, thereby preventing the abutment plate 431 from rotating relative to the connecting block 3, thereby fixing the position of the screw 43, and further preventing the upper clamping plate 46 and the bottom plate 41 from rotating.

[0035] Then, adjust the lower clamping assembly 4. Similarly, first loosen the top rod 45, then rotate the angle of the upper clamping plate 46 and the bottom plate 41 so that they can clamp the other end of the workpiece. Then adjust the height of the upper clamping plate 46 so that the workpiece is clamped between the upper clamping plate 46 and the bottom plate 41. Finally, tighten the top rod 45 to fix the position of the upper clamping plate 46 and the bottom plate 41, thus completing the workpiece fixing.

[0036] It is understandable that the connecting block 3 has a clearance groove (which is obscured in the figure) that follows the rotation trajectory of the screw 43, allowing the base plate 41 and the upper clamping plate 46 to rotate around the pivot 42, thereby driving the screw 43 to rotate. In other words, the screw 43 does not restrict the rotation of the base plate 41 and the upper clamping plate 46.

[0037] By adjusting the angles and positional relationship between the upper clamping component 4 and the lower clamping component 4, workpieces of different shapes can be fixed.

[0038] In use, first fix the workpiece to be welded onto the clamping assembly 4, then adjust the angle of the connecting block 3 to perform the welding operation. Obviously, you can also adjust the angle of the connecting block 3 first, and then fix the workpiece to be welded onto the clamping assembly 4.

[0039] Finally, it should be noted that the above-listed embodiments are merely preferred embodiments of the present invention. Of course, those skilled in the art can make modifications and variations to the present invention. If such modifications and variations fall within the scope of the claims of the present invention and their equivalents, they should be considered as being within the protection scope of the present invention.
