[0021] The second embodiment, please refer to Figures 1-4 On the basis of the first embodiment, the application provides a technical scheme: the embedded column 303 comprises a fixed column 3031, the side surface of the fixed column 3031 is provided with a rotating groove 3032, the part of the fixed column 3031 located on one side of the rotating groove 3032 is fixedly connected with a sliding rod 3033, the side surface of the sliding rod 3033 is fixedly connected with a spring sheet 3034, the sliding rod 3033 extends into the side surface of the driving assembly 2, and the side surface of the fixed column 3031 is fixedly connected with the side surface of the hollow tapping rod 301.

The workpiece enters the side of the hollow tapping rod 301 along the fitting seat 3042 and enters the side of the fixed column 3031 for fitting, thus facilitating the tapping of workpieces one by one. Compared with the traditional reciprocating tapping process, it is more convenient for the batch processing of a large number of workpieces in an assembly line.

[0024] Third embodiment, please refer to Figures 1-6 Based on the second embodiment, the present invention provides a technical solution: the pushing device 4 includes a rotating bracket 401, the side of the rotating bracket 401 is rotatably connected to the fixed end of the first telescopic rod 402, the side of the movable end of the first telescopic rod 402 is fixedly connected to an auxiliary bracket 403, the side of the auxiliary bracket 403 is fixedly connected to the fixed end of the second telescopic rod 404, the movable end of the second telescopic rod 404 is fixedly connected to a support ring 405, the movable end of the first telescopic rod 402 is fixedly connected to a connecting device 406, the support ring 405 is sleeved on the side of the movable end of the first telescopic rod 402 and is slidably connected to the side of the movable end of the first telescopic rod 402, the connecting device 406 extends into the interior of the sliding groove 3044 and is slidably connected to the interior of the sliding groove 3044, and the bottom of the rotating bracket 401 is fixedly connected to the top of the equipment base 1.

[0025] The connecting device 406 includes a sliding post 4061, a positioning post 4062 fixedly connected to the side of the sliding post 4061, a fitting rod 4063 fixedly connected to the side of the positioning post 4062, a sliding ring 4064 sleeved and slidably connected to the side of the sliding post 4061, a fixing spring 4065 fixedly connected to the side of the sliding ring 4064, a guide bar 4066 fixedly connected to the side of the sliding ring 4064, a fixing ring 4067 fixedly connected to the end of the fixing spring 4065 away from the sliding ring 4064, a sliding groove adapted to the guide bar 4066 opened on the side of the fixing ring 4067, the side of the fixing ring 4067 fixedly connected to the side of the sliding post 4061, the positioning post 4062 contacting the side of the fitting seat 3042, and the fitting rod 4063 disposed inside the braking groove 3045.

[0026] The second telescopic rod 404 and the first telescopic rod 402 are preset to the retracted state. The workpiece is first fitted onto the side of the movable end of the first telescopic rod 402. The workpiece slides along the movable end of the first telescopic rod 402 through the side of the sliding column 4061. After the workpiece is fitted, the first telescopic rod 402 is activated. The movable end of the first telescopic rod 402 drives the sliding column 4061 to move. The movement of the sliding column 4061 drives the positioning column 4062 to move. The movement of the positioning column 4062 drives the fitting rod 4063 to move into the inner wall of the sliding groove 3044 and slide. After the hollow tap rod 301 rotates, the hollow tap rod 304 rotates. The rotation of the lead screw 301 drives the guide cone 3041 to rotate, which in turn drives the fitting seat 3042 to rotate.

Between the sliding ring 4067 and the fixed ring 4064, the elastic force of the fixed spring 4065 drives the sliding ring 4064 and the fixed ring 4067 to move, thereby ensuring that the fitting rod 4063 is stuck inside the brake groove 3045, thus preventing it from coming out. While the sliding ring 4064 slides, it drives the guide bar 4066 to slide along the side of the fixed ring 4067. When the workpiece moves along the movable end of the first telescopic rod 402, the second telescopic rod 404 is activated. The movable end of the second telescopic rod 404 drives the support ring 405 to move. The movement of the support ring 405 drives the workpiece to move along the movable end of the first telescopic rod 402. Under the push of the support ring 405, the workpiece moves along... Supported by the guide bar 4066, the hollow tapping rod 301 enters the side of the guide cone 3041 along the fitting seat 3042, thereby making contact between the side of the hollow tapping rod 301 and the side of the workpiece. Under the push of the support ring 405, tapping is performed. The guide bar 4066 facilitates the sliding of the workpiece along the side of the guide bar 4066, thereby facilitating the movement of the workpiece along the movable end of the first telescopic rod 402. The nested sliding insertion and continuous tapping of the workpiece are achieved by fixing and disengaging the two ends of the hollow tapping rod 301. The fixed connection at both ends facilitates the stabilization of the rotation state of the hollow tapping rod 301, thereby achieving stable tapping.

[0029] The third telescopic rod 205 is activated. The movable end of the third telescopic rod 205 drives the sliding base 202 to slide along the top of the fixed slide 201. The sliding base 202 slides on the top of the fixed slide 201, driving the motor 203 to move. The movement of the motor 203 drives the drive base 2041 to move. The drive base 2041 moves and engages with the side of the fixed column 3031. The guide plate 206 is set to squeeze and guide the side of the workpiece, thereby facilitating the sliding state of the workpiece and preventing it from rotating passively with the rotation of the hollow tapping rod 301.
