[0017] The present invention will be described in further detail below with reference to the accompanying drawings.

[0018] Combined with attachment Figure 1-4As shown, a conveniently adjustable bench tapper includes a fixed base 1 and a tapping die 2. The fixed base 1 is provided with a plurality of fastening mechanisms 17. The fastening mechanism 17 includes a screw rod 18 that passes through the fixed base 1. The screw rod 18 is threadedly connected to the fixed base 1. A fastening suction cup 19 is fixed at the bottom end of the screw rod 18. A support rod 3 is fixed to the center of the top surface of the fixed base 1. The other end of the support rod 3 is connected to an extension plate 4. A rotating motor 16 is embedded in the support rod 3. The output end of the rotating motor 16 is fixedly connected to the bottom surface of the extension plate 4. The extension plate 4 is provided with a screw rod 18 that passes through the fixed base 1. A through slot 5 is provided in which a hydraulic telescopic rod 6 is fixed, and the other end of the hydraulic telescopic rod 6 is connected to a moving frame 7. The inner wall of the through slot 5 is provided with a slide groove 20 that is slidably connected with the moving frame 7. The moving frame 7 is rotatably provided with an adjustment plate 8 at one end away from the hydraulic telescopic rod 6. An adjustment motor 9 for driving the adjustment plate 8 is provided on the outer wall of the moving frame 7. A downward pressure cylinder 10 is fixed on the top surface of the adjustment plate 8. The output end of the downward pressure cylinder 10 is connected to a lifting frame 11 located below the adjustment plate 8. A tapping motor 12 is provided in the lifting frame 11, and the tapping die 2 is connected to the output end of the tapping motor 12;

[0019] Through the above structure, the equipment is first placed close to the tapping surface through the fixed base 1, and then the screw rod 18 is rotated to make the fastening suction cup 19 close to the stable plane to complete the stable placement of the device. Then, the position of the tapping die 2 is adjusted, and the tapping die 2 can be rotated 360 degrees by setting the rotating motor 16. The horizontal position of the tapping die 2 is adjusted by the contraction of the hydraulic telescopic rod 6. During the telescopic adjustment process of the hydraulic telescopic rod 6, the slide groove 20 cooperates to improve the stability of the adjustment. When necessary, the adjusting motor 9 is turned on to make the adjusting plate 8 rotate a certain angle until the tapping die 2 corresponds to the tapping position, and the downward pressure cylinder 10 is turned on to push the tapping die 2 to make it close to the top surface of the tapping position. Then, the tapping motor 12 is turned on to make the tapping die 2 rotate to perform tapping work. During the tapping process, the tapping depth is adjusted by the work of the downward pressure cylinder 10 to achieve precise tapping operation and improve tapping quality and efficiency.

[0020] The bottom surface of the lifting frame 11 is rotatably provided with a mounting sleeve 13 fixedly connected to the output end of the tapping motor 12, and the tapping die 2 is extended and arranged in the mounting sleeve 13. A group of threaded rods 14 are symmetrically threadedly connected on the mounting sleeve 13. One end of the threaded rod 14 extends into the mounting sleeve 13 and is arranged close to the tapping die 2. The other end of the threaded rod 14 is provided with a handle 15 located outside the mounting sleeve 13;

[0021] Through the above structure, a suitable tapping die 2 is selected according to the workpiece, the tapping die 2 is placed in the mounting sleeve 13, and then the threaded rod 14 is rotated until the threaded rod 14 is close to the outer wall of the tapping die 2 to complete the fixed installation operation of the tapping die 2.

[0022] During the specific implementation of the present invention, the device is first placed close to the tapping surface through the fixed base 1, and then the screw rod 18 is rotated so that the fastening suction cup 19 is close to the stable plane to complete the stable placement of the device. A suitable tapping die 2 is selected according to the workpiece, and the tapping die 2 is placed in the mounting sleeve 13. Then, the threaded rod 14 is rotated until the threaded rod 14 is close to the outer wall of the tapping die 2, completing the fixed installation operation of the tapping die 2.

[0023] Then adjust the position of the tapping die 2. The tapping die 2 can be rotated 360 degrees by setting the rotating motor 16. The horizontal position of the tapping die 2 is adjusted by contracting the hydraulic telescopic rod 6. During the telescopic adjustment process of the hydraulic telescopic rod 6, the slide groove 20 cooperates to improve the stability of the adjustment. When necessary, turn on the adjustment motor 9 to rotate the adjustment plate 8 to a certain angle until the tapping die 2 corresponds to the tapping position. Turn on the downward pressure cylinder 10 to push the tapping die 2 to make it close to the top surface of the tapping position. Then turn on the tapping motor 12 to rotate the tapping die 2 to perform tapping. During the tapping process, the tapping depth is adjusted by the operation of the downward pressure cylinder 10 to achieve precise tapping operation and improve the tapping quality and efficiency.
