Description

Technical Field

[0001] The utility model relates to the technical field of fixture manufacturing, in particular to a welding pneumatic fixture with a positioning and clamping structure. Background Art

[0002] Welding is an indispensable and important process in modern manufacturing. It connects metal materials together to manufacture various structures and products. However, in the welding process, how to ensure the accurate positioning and stable fixation of the workpiece is a key issue. In order to solve this problem, welding pneumatic clamps came into being.

[0003] A welding pneumatic clamp is a tool that uses the principle of air pressure to clamp and fix the workpiece. It consists of one or more clamping jaws, a cylinder, an air source, and a control system. When the air source provides pressure, the piston in the cylinder pushes the clamping jaws to close, thereby clamping the workpiece. By controlling the pressure and flow of the air source, precise control of the clamping force can be achieved.

[0004] However, in the prior art, pneumatic clamps are usually designed and manufactured according to the specific shape and size of the workpiece. When the shape of the workpiece is complex or varied, the applicability of the pneumatic clamp may be limited. For example, when the workpiece is too large or too small, the workpieces of different shapes may not be able to fully contact each clamping plate of the pneumatic clamp, resulting in insufficient clamping force, and the workpiece may loosen or move during the welding process, resulting in reduced welding quality. Therefore, we provide a welding pneumatic clamp with a positioning clamping structure. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and provide a welding pneumatic clamp with a positioning and clamping structure.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a welding pneumatic clamp with a positioning and clamping structure, comprising: a clamping mechanism, a supporting mechanism is arranged at the top of the clamping mechanism, the clamping mechanism comprises a workbench, a clamping cylinder is arranged on one side of the top of the workbench, an air inlet is arranged on one side of the clamping cylinder, clamping plates are arranged on both sides of the top of the clamping cylinder, sliding blocks are arranged on the bottom sides of the two clamping plates away from the air inlet, a guide rod is arranged between the two sliding blocks, fixed seats are arranged at both ends of the guide rod, a connecting shell is arranged on one side of the two clamping plates, two adjusting blocks are arranged inside the two connecting shells, a bidirectional screw is arranged on the inner wall of the threaded groove of the adjusting block, and a clamping block is arranged on the side close to the clamping plate of the four adjusting blocks.

[0007] As a preferred embodiment, the support mechanism includes a support seat, the bottom of the support seat is fixedly connected to the top of the workbench, and the top of the support seat is fixedly connected with an anti-slip pad.

[0008] As a preferred embodiment, one side of the top of the workbench is fixedly connected to the bottom of the clamp cylinder, and a slider is fixedly connected to the bottom side of the two clamp plates away from the air inlet.

[0009] As a preferred implementation, the interiors of the two sliding blocks are slidably connected to the outer wall of the guide rod, and the two ends of the guide rod are fixedly connected to one side of the two fixing seats respectively.

[0010] As a preferred embodiment, the bottoms of the two fixing seats are fixedly connected to a side of the top of the workbench away from the clamping cylinder, and one side of the two clamping plates is fixedly connected to a connecting shell.

[0011] As a preferred implementation, the inner wall of the connecting shell is slidably connected to the outer wall of the adjusting block, and the inner walls of the two adjusting blocks are respectively threadedly connected to different threaded portions of the bidirectional screw.

[0012] As a preferred embodiment, one end of the bidirectional screw passes through a slot provided on one side of the connecting shell and is rotatably connected to one side of the inner wall of the connecting shell.

[0016] The installed support mechanism can provide a stable support platform for the workpiece, ensuring that the workpiece will not shake or tilt when placed. At the same time, the support seat can also provide a clamping reference during the workpiece processing process, making it easier for the fixture to position and fix the workpiece, which is beneficial to improving processing efficiency and accuracy. Secondly, the support mechanism can also prevent direct contact between the workpiece and the support seat to prevent scratches, wear and other damages on the workpiece surface, which helps to protect the workpiece surface.

The bottom of the fixed seat 17 is fixedly connected to the side of the top of the workbench 11 away from the clamping cylinder 12, and a connecting shell 18 is provided on one side of the two clamping plates 14. The connecting shell 18 is fixedly connected to the two clamping plates 14 on one side. Two adjusting blocks 19 are provided inside the two connecting shells 18. The inner wall of the connecting shell 18 is slidably connected to the outer wall of the adjusting block 19. A bidirectional screw 110 is provided on the inner wall of the threaded groove provided in the adjusting block 19. The inner walls of the two adjusting blocks 19 are respectively threadedly connected to different threaded parts of the bidirectional screw 110. One end of the bidirectional screw 110 passes through a slot provided on one side of the connecting shell 18 and is rotatably connected to one side of the inner wall of the connecting shell 18. A clamping block 111 is provided on one side of the four adjusting blocks 19 close to the clamping plate 14. The outer wall of the adjusting block 19 close to the clamping plate 14 is slidably connected to the inner wall of the clamping plate 14. The clamping block 111 is fixedly connected on one side of the four adjusting blocks 19 close to the clamping plate 14.

[0027] In this embodiment, when the worker uses the welding pneumatic clamp to position and clamp the workpiece, he can place the workpiece on the anti-skid pad 22 and start the clamping jaw cylinder 12. When the gas source enters the clamping jaw cylinder 12 through the air inlet 13, the gas will push the piston in the clamping jaw cylinder 12 to move forward, thereby driving the clamping jaw plate 14 connected to the piston to open and close, so that the clamping block 111 positions and clamps the workpiece on the anti-skid pad 22. The surface of the clamping block 111 is provided with a soft pad, which can provide additional buffering and protection, effectively reducing the friction and wear between the clamping block 111 and the workpiece, and the guide rod 1 is provided with 6. The slider 15 and the fixed seat 17 can provide support for the clamping plate 14, and can also ensure the moving trajectory of the clamping plate 14 when opening and closing, so that it can maintain smooth and accurate movement during the opening and closing process, thereby improving the working efficiency of the clamping plate 14. When the staff needs to position and clamp workpieces of different sizes and shapes, the spacing of the clamping block 111 can be adjusted to the position of the workpiece by rotating the bidirectional screw 110, so that the surface of the clamping block 111 can fully contact the workpieces of different shapes, avoiding the loosening or damage of the workpiece due to loose clamping, and ensuring the stability and accuracy of clamping.

[0028] Example 2

[0029] like Figure 1-Figure 4 As shown, the support mechanism 2 includes a support seat 21 , the bottom of the support seat 21 is fixedly connected to the top of the workbench 11 , and the top of the support seat 21 is fixedly connected to an anti-slip pad 22 .

[0030] In this embodiment, when the workpiece is placed on the support seat 21, the support seat 21 can provide a stable support platform for the workpiece, ensuring that the workpiece will not shake or tilt when placed thereon. At the same time, the support seat 21 can also provide a clamping reference during the workpiece processing process, making it easier for the fixture to position and fix the workpiece, which is beneficial to improving processing efficiency and accuracy. In addition, the anti-slip pad 22 can also prevent direct contact between the workpiece and the support seat 21, so as to prevent scratches, wear and other damages on the workpiece surface, which helps to protect the workpiece surface.

[0031] Working principle:

[0032] like Figure 1-Figure 4As shown, when the worker uses the welding pneumatic clamp to position and clamp the workpiece, the workpiece can be placed on the anti-skid pad 22, and the support seat 21 at the bottom of the anti-skid pad 22 can provide a clamping reference during the workpiece clamping process. The worker can start the clamping jaw cylinder 12. When the air source enters the clamping jaw cylinder 12 through the air inlet 13, the gas will push the piston in the clamping jaw cylinder 12 to move forward, thereby driving the clamping jaw plate 14 connected to the piston to open and close, so that the clamping block 111 positions and clamps the workpiece on the anti-skid pad 22. During the opening and closing process of the two clamping plates 14, the sliders 15 at the bottom of the two clamping plates 14 will move back and forth on the guide rails, which can not only provide support for the clamping plates 14, but also ensure the moving trajectory of the clamping plates 14 for opening and closing, so that they can maintain smooth and accurate movement during the opening and closing process. When the staff needs to position and clamp workpieces of different sizes and shapes, they can adjust the spacing of the clamping blocks 111 to the position of the workpiece by rotating the bidirectional screw 110, so that the surface of the clamping blocks 111 can fully contact the workpieces of different shapes.
