[0025] According to this specific embodiment, the base frame 2 is fixedly connected to the workbench 1 and is located on the top of the workbench 1; the support seat 3 is fixedly connected to the base frame 2 and is located on the side of the base frame 2; the driving component 4 is arranged on the top of the support seat 3; the rotating shaft 5 is rotatably arranged on the driving component 4; the driven wheel 6 is fixedly connected to the rotating shaft 5 and is located at the bottom of the rotating shaft 5; the lifting shaft 7 is slidably connected to the driven wheel 6 and is located on the inner side of the driven wheel 6; the drill bit 9 clamp 8 is fixedly connected to the lifting shaft 7 and is located at the bottom of the lifting shaft 7; the drill bit 9 is fixedly connected to the drill bit 9 clamp 8 and is located at the bottom of the drill bit 9 clamp 8; the inner ring of the bearing 10 is fixedly connected to the lifting shaft 7 and is located on the outside of the lifting shaft 7; the sleeve 11 is fixedly connected to the outer ring of the bearing 10 and is located on the outside of the bearing 10; the connecting rod 12 is fixedly connected to the sleeve 11 and is located on the side of the sleeve 11; the cylinder 13 is fixedly connected to the support seat 3, and the output rod of the cylinder 13 is fixedly connected to the connecting rod 12 and is located on the side of the support seat 3; the fixing component 14 is arranged on the top of the workbench 1. The inner side of the driven wheel 6 is provided with a slot hole adapted to the lifting shaft 7. The cross section of the lifting shaft 7 is non-circular, and can be a square cross section or a gear-like cross section. The purpose is to enable the lifting shaft 7 to be lifted and slid inside the driven wheel 6, and at the same time, the driven wheel 6 can also drive the lifting shaft 7 to rotate when it rotates. When the hole of the upper frame of the door is expanded, the upper frame of the door is first fixed on the fixing component 14, and then the cylinder 13 and the driving component 4 are turned on. The driving component 4 drives the driven wheel 6 to rotate, and the driven wheel 6 drives the The lifting shaft 7 rotates, and the lifting shaft 7 drives the drill bit 9 clamp 8 and the drill bit 9 to rotate. Since a bearing 10 is provided between the sleeve 11 and the lifting shaft 7, the lifting shaft 7 will not drive the sleeve 11 to rotate. At the same time, the cylinder 13 drives the connecting rod 12 and the sleeve 11 to move downward, and the sleeve 11 drives the bearing 10 and the lifting shaft 7 to move downward, and the lifting shaft 7 drives the drill bit 9 to move downward to expand the hole in the upper frame of the vehicle door. Through the above method, the upper frame of the vehicle door can be expanded conveniently, reducing the labor intensity of the staff.

[0026] The mounting shell 15 is fixedly connected to the support seat 3 and is located at the top of the support seat 3; the motor 16 is fixedly connected to the mounting shell 15 and is located at the bottom of the mounting shell 15; the driving wheel 17 is fixedly connected to the output end of the motor 16 and is located inside the mounting shell 15; the transmission belt 18 is sleeved on the sides of the driving wheel 17 and the driven wheel 6.

The limiting plate 25 is fixedly connected to the rotary clamping cylinder 23 and is located on the side of the rotary clamping cylinder 23. The holding member 24 is driven to move by the rotary clamping cylinder 23, so that the holding member 24 rotates to the upper part of the door frame and then moves downward, so that the holding member 24 presses on the upper part of the door frame, fixes the position of the door frame, and prevents the door frame from moving when expanding the hole. The limiting plate 25 is used to limit the position of the holding member 24 to prevent the upper door frame from moving due to the movement of the holding member 24.

[0029] In addition, the slider 26 is fixedly connected to the sleeve 11, and is slidably connected to the support seat 3, and is located at the side of the support seat 3; the guide rod 27 is fixedly connected to the slider 26, and is located at the side of the slider 26, and penetrates the support seat 3. The slider 26 and the guide rod 27 are used to provide guidance for the sleeve 11 to prevent the sleeve 11 from rotating, and prevent the sleeve 11 from deviating when moving longitudinally, thereby preventing the position of the drill bit 9 from deviating.

[0030] Furthermore, a plurality of universal wheels 28 are respectively arranged at the bottom of the workbench 1. The plurality of universal wheels 28 can facilitate the movement of the position of the workbench 1.

[0031] Finally, the button switch box 29 is fixedly connected to the workbench 1, and is electrically connected to the cylinder 13, the motor 16 and the rotary clamping cylinder 23, respectively, and is located on the side of the workbench 1. The staff can control the start and stop of the cylinder 13, the motor 16 and the rotary clamping cylinder 23 by pressing the control button on the button switch box 29.

[0032] When using the present invention to expand the hole of the upper door frame, the staff first places the upper door frame on the first support platform 20 and the second support platform 22, and then presses the start button on the button switch box 29, and the rotary clamping cylinder 23 first drives the holding member 24 to rotate to the upper part of the door frame and then moves downward, so that the holding member 24 is pressed on the upper part of the door frame to fix the position of the door frame, and then the motor 16 is turned on to drive the driving wheel 17 to rotate, and the driving wheel 17 drives the driven wheel 6 to rotate through the transmission belt 18, and the driven wheel 6 drives the lifting shaft 7 to rotate, and the lifting shaft 7 drives the drill 9 clamp 8 and the drill 9 to rotate. A bearing 10 is provided, so the lifting shaft 7 will not drive the sleeve 11 to rotate, and then the cylinder 13 will drive the connecting rod 12 and the sleeve 11 to move downward, and the sleeve 11 drives the bearing 10 and the lifting shaft 7 to move downward, and the lifting shaft 7 drives the drill bit 9 to move downward to expand the hole in the upper frame of the door; after the expansion is completed, the motor 16 stops running, and at the same time, the cylinder 13 drives the drill bit 9 to move up and reset, and then the rotary clamping cylinder 23 drives the holding piece 24 to move up and rotate, so that the holding piece 24 is away from the upper frame of the door, and then the staff can remove the expanded upper frame of the door; through the above method, the upper frame of the door can be expanded conveniently, reducing the labor intensity of the staff.
