[0003] In the existing technology, during the tapping process of a workpiece, it is often necessary to use a clamping fixture corresponding to the workpiece. However, different workpieces require different clamping fixtures. Some tapping fixtures are integrated with the tapping drill machine, which means that a single tapping drill machine cannot clamp different types of workpieces. This results in a single tapping drill machine being able to process only one or a few types of workpieces, limiting its processing range. If different types of workpieces need to be processed, other tapping drill machines need to be purchased, which greatly increases the processing cost. Utility Model Content
[0004] The purpose of this utility model is to provide a detachable tapping fixture, which can be replaced as a whole according to the type of workpiece being processed, so that a single tapping drill can process different types and sizes of workpieces, thereby expanding its processing range and reducing the overall cost of processing operations.

Corresponding to the first insertion hole 11, the first locking pin 35 is inserted into the first insertion hole 11, and the second locking pin 36 is corresponding to the second insertion hole 12. The second locking pin 36 is inserted into the second insertion hole 12. A clamping device 4 is provided above the workbench 1. The bottom of the clamping device 4 is composed of a clamping seat 41. The lower left and right sides of the clamping seat 41 are fixedly connected to the second slider 42. The second slider 42 is located inside the slide groove 2 and is slidably connected to the slide groove 2. A slot 43 is provided in the middle of the clamping seat 41. Fixed plates 44 are fixedly connected to the front and rear sides of the clamping seat 41. A clamping screw 45 is threadedly connected to the front of the front fixed plate 44. A first knob 46 is fixedly connected to the front of the clamping screw 45. A clamping plate 47 is rotatably connected to the other end of the clamping screw 45.
[0031] The above structure, by providing a locking device 3, causes the spring 33 to contract when the left and right pressure blocks 34 are pressed towards the center. At this time, the first locking pin 35 and the second locking pin 36 simultaneously enter the interior of the locking frame 31. The operator can then insert the locking device 3 into the interior of the slide groove 2 or remove it from the interior of the slide groove 2. The operator can then remove the clamping device 4 and replace it with a different type of clamping device 4.
[0032] By using a clamping device 4, the clamping screws 45 are rotated by turning the first knobs 46 on both sides. The clamping screws 45 are threadedly connected to the fixed plate 44, allowing the left and right clamping screws 45 to move independently above the fixed plate 44 on one side. The other end of the clamping screws 45 is rotatably connected to a clamping plate 47, allowing the clamping plate 47 to move independently above the clamping seat 41. This allows the operator to adjust the first knobs 46 on both sides to clamp different positions of the workpiece at the center of the slot 43, enabling the device to perform drilling processing on different positions of the workpiece.
[0033] A connecting plate 5 is fixedly connected to the left side of the workbench 1. An electric telescopic rod 6 is fixedly connected to the bottom of the connecting plate 5. A connecting frame 7 is fixedly connected to the output end of the electric telescopic rod 6. A drive motor 8 is fixedly connected inside the connecting frame 7. A drill bit chuck 9 is provided at the output end of the drive motor 8. The outer shell of the drill bit chuck 9 is composed of a clamping frame 91.

The third slider 94 is located inside the clamping frame 91 and is slidably connected to the clamping frame 91. A gripper 95 is fixedly connected to the bottom of the third slider 94. Support columns 10 are fixedly connected to the four corners below the workbench 1. A first insertion hole 11 is opened on the upper left and right sides of the slide groove 2. A second insertion hole 12 is opened on the lower left and right sides of the slide groove 2.
[0034] The above structure, driven by the electric telescopic rod 6, enables the drive motor 8 to move up and down below the connecting plate 5, and the drive motor 8 causes the drill bit chuck 9 to rotate.
[0035] By rotating the second knob 92, the bidirectional lead screw 93 is rotated. The left and right sides of the bidirectional lead screw 93 are threadedly connected to the third slider 94, so that the left and right third sliders 94 are located inside the clamping frame 91 and move towards the center at the same time, or slide towards the left and right at the same time. As the third sliders 94 move towards the center, the jaws 95 move towards the center. With the cooperation of the left and right jaws 95, the tapping drill bit can be clamped.
[0036] By rotating the second knob 92, the left and right jaws 95 move to the left and right sides, thereby loosening their grip on the tapping drill bit. This allows the operator to change to different tapping drill bits depending on the size of the tapping hole.
[0037] Working principle: When using this detachable tapping fixture, first place the workpiece above the slot 43, and then control the first knob 46 on the left and right sides respectively to make the clamping plates 47 on the left and right sides stably clamp the workpiece. Then, rotate the second knob 92 to install the tapping drill bit under the drill bit holder 9. Finally, turn on the switch of the drive motor 8 and the switch of the electric telescopic rod 6. The workpiece can be drilled by the cooperation of the two.
[0038] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
