Description

Technical Field

[0001] The utility model relates to the technical field of profile processing fixtures, in particular to a fixture for tapping aluminum alloy profiles. Background Art

[0002] Tapping is a very common technique in mechanical processing technology. A Chinese patent (application announcement number: CN203542130U) discloses a tapping fixture for a filter end cover. It includes a circular base and at least two T-shaped positioning grooves inverted in the radial direction of the circular base. A T-shaped slider matching the T-shaped positioning groove is arranged in the T-shaped positioning groove. A positioning pin and a locking bolt are arranged on the T-shaped slider. The diameter of the positioning pin matches the hole on the filter end cover to be processed. The central angle between the T-shaped positioning grooves is equal to the central angle between the holes on the filter end cover corresponding to the positioning pins on the positioning grooves.

[0003] However, the clamping effect of the above-mentioned device on the profile needs to be improved. Since the clamp shape is conventional and not easy to replace, the clamping effect for profiles of different shapes is difficult to achieve the expected effect. At the same time, if tapping is performed at different positions of the same profile, the clamp needs to be loosened and re-fixed, which wastes time and seriously affects production efficiency. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the utility model is to provide a clamp for tapping aluminum alloy profiles, which can effectively clamp profiles of different shapes, improve the versatility of the device, and at the same time can tap different surfaces of the same profile without disassembly and re-fixing, thereby greatly improving production efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fixture for tapping aluminum alloy profiles, comprising a workbench, on which a clamping assembly and a tapping assembly are installed,

[0006] The clamping assembly comprises a sliding hole arranged on the workbench, and two clamping blocks are slidably installed in the sliding hole, and a driving assembly for driving the two clamping blocks to move is provided at the bottom of the workbench;

[0007] The clamping blocks are rectangular, and the two clamping blocks are provided with a semicircular first clamping groove on one side thereof, and a triangular second clamping groove is provided on the clamping blocks, and the second clamping groove is connected with the first clamping groove;

[0008] By adjusting the shape of the clamping block, when tapping and fixing a rectangular workpiece or an angular workpiece, it is only necessary to make the two opposite corners on the workpiece contact the groove corners of the two first clamping grooves on the two clamping blocks respectively to clamp the workpiece.

[0009] When the arc-shaped workpiece needs to be clamped, it only needs to be placed between the two clamping blocks, and the workpiece can be effectively clamped through the semicircular first clamping groove.

[0010] The tapping assembly comprises a tapping machine and a support rod.

[0011] As a preferred technical solution of the utility model, the support rod is rotatably installed on the workbench.

[0012] As a preferred technical solution of the utility model, a semicircular groove is provided on the adjacent surfaces of the two clamping blocks, and the cross sections of the grooves on the two clamping blocks can form a closed circle.

[0015] When in use, the rotating rod is rotated and the two nuts on the rotating rod are used to move the two clamping blocks closer to or farther from each other, thereby achieving rapid tightening or loosening of the workpiece.

[0016] As a preferred technical solution of the utility model, a rotating shaft is rotatably mounted on each of the two sliding blocks, and the two clamping blocks are respectively mounted on the corresponding rotating shafts.

[0017] As a preferred technical solution of the utility model, a worm wheel is installed on one of the two rotating shafts, and a worm for driving the worm wheel to rotate is rotatably installed on the corresponding sliding block.

[0018] By installing the rotating shaft and the worm gear, when the angle of the workpiece needs to be adjusted, only the worm gear needs to be rotated to achieve the change of the workpiece angle. At the same time, the worm gear has the function of reverse locking, so it has a more effective fixing effect after the workpiece angle is adjusted.

[0019] As a preferred technical solution of the utility model, it also includes a tightening mechanism, and the tightening mechanism includes a top plate located above the workbench and capable of tightening the workpiece.

[0020] As a preferred technical solution of the utility model, the jacking mechanism also includes a jacking rod threadedly mounted on the workbench, and the ejector plate is rotatably mounted on the jacking rod.

[0021] As a preferred technical solution of the utility model, the tightening mechanism also includes a slide bar fixed to the bottom of the top plate, and the slide bar is slidably mounted on the workbench.

At the same time, the worm gear has a reverse locking function, so it has a more effective fixing effect after the workpiece angle is adjusted, thereby improving the stability of the workpiece during tapping.

The clamping blocks 7 are close to or far away from each other, thereby realizing quick tightening or loosening of the workpiece. The clamping block 7 is rectangular, and the two clamping blocks 7 are provided with a semicircular first clamping groove 71 on the side facing closer to each other. The clamping block 7 is provided with a triangular second clamping groove 72, and the second clamping groove 72 is connected to the first clamping groove 71. By adjusting the shape of the clamping block 7, when a rectangular workpiece or an angular workpiece is tapped and fixed, it is only necessary to make the two opposite corners on the workpiece contact with the groove angles of the two first clamping grooves 71 on the two clamping blocks 7 respectively to achieve the jamming of the workpiece and avoid the rotation of the workpiece, thereby improving the clamping effect of the rectangular workpiece. When it is necessary to clamp the arc-shaped workpiece, it is only necessary to place it between the two clamping blocks 7, and the workpiece can be effectively tightened by the semicircular first clamping groove 71. The semicircular first clamping groove 71 has a better fitting effect on the cylindrical workpiece, thereby improving the clamping stability. The first clamping groove 71 and the second clamping groove 72 are processed and formed using the structure shown in the figure.

[0033] For other specific implementations of the present invention, see Figure 2 The two clamping blocks 7 are each provided with a semicircular groove 73 on one side thereof close to each other, and the cross-section of the groove 73 on the two clamping blocks 7 can form a closed circle. In order to meet the need for tapping a tubular slender workpiece during tapping, the groove 73 is provided on the two clamping blocks 7. When in use, the tubular workpiece is clamped in the groove 73, thereby achieving effective clamping of the workpiece, further improving the versatility of the clamp.

When in use, tapping is often performed on different positions of the workpiece. In order to avoid repeatedly disassembling and re-fixing the workpiece, by installing the cooperation of the rotating shaft 14 and the worm wheel 5 and worm 6, when the angle of the workpiece needs to be adjusted, it is only necessary to rotate the worm 6 to achieve the change of the workpiece angle. At the same time, the worm wheel 5 and worm 6 have the function of reverse locking, so it has a more effective fixing effect after the workpiece angle is adjusted, thereby improving the stability of the workpiece during tapping.

[0036] A set of clamps can be used to effectively clamp profiles of different shapes, avoiding the need to replace different clamps, reducing the company's equipment costs, while improving production efficiency and further enhancing the versatility of the clamp.

[0037] Avoid repeatedly disassembling and re-fixing the workpiece. By installing the rotating shaft and the worm gear, when the angle of the workpiece needs to be adjusted, you only need to rotate the worm to change the angle of the workpiece. At the same time, the worm gear has a reverse locking function, so it has a more effective fixing effect after the workpiece angle is adjusted, thereby improving the stability of the workpiece during tapping.
