The spherical surface of the connecting block 407 contacts the inner wall of the connecting groove 406.

[0025] A guide groove 410 is defined on the inner bottom wall of the limiting groove 303. A guide block 411 is slidably disposed within the guide groove 410, with the top surface of the guide block 411 fixedly connected to the bottom surface of the limiting sleeve 304. Both the guide groove 410 and the guide block 411 are arc-shaped structures, with the centers of the guide groove 410 and the guide block 411 both aligned with the axis of the spindle motor 103 output shaft, facilitating the sliding of the guide block 411 within the guide groove 410.

[0027] As a preferred embodiment, the device further includes a clamping assembly 5 ; the clamping assembly 5 is arranged on the workbench 102 . The clamping assembly 5 includes a fixed base 501, a fixed plate 502, a movable groove B503, a movable block 504, a movable plate 505, a screw 506, a U-shaped frame A507, a movable groove 508, a movable block 509, a U-shaped frame B510, a U-shaped frame C511 and a rotating plate 512; the fixed base 501 is fixed on the top surface of the workbench 102; the fixed plate 502 is fixed on the left side of the top surface of the fixed base 501; a movable groove B503 is provided on the fixed base 501; the movable block 504 is slidably arranged in the movable groove B503; the movable plate 505 is slidably arranged on the top surface of the fixed base 501, and the bottom surface of the movable plate 505 is fixedly connected to the top surface of the movable block 504; one end of the screw 506 is rotatably connected to the left inner wall of the movable groove B503 through a rotating shaft, and the other end extends to the outside through the movable groove B503, and the screw 506 is connected to the movable block 504 threaded connection; two U-shaped frames A507 are symmetrically fixed on the opposite surfaces of the fixed plate 502 and the movable plate 505 respectively; a moving groove 508 is opened in each U-shaped frame A507; two moving blocks 509 are slidably provided in each moving groove 508, and the U-shaped frame B510 is fixed on the inner end surface of the moving block 509; six U-shaped frames C511 are symmetrically arranged between the fixed plate 502 and the movable plate 505, and the inner end surface of the U-shaped frame C511 can contact the gearbox housing; the inner end portions of two adjacent rotating plates 512 are rotatably connected to the outer end surfaces of the corresponding U-shaped frames C511 through the rotating axis A, and the outer end portions of two adjacent rotating plates 512 are rotatably connected to the inner end surfaces of the corresponding U-shaped frames B510 through the rotating axis B, and the outer end portions of the two rotating plates 512 at the edge are rotatably connected to the inner end surfaces of the U-shaped frame A507 through the rotating axis C.

[0028] The moving block 509 is a T-shaped structure, and the size of the moving block 509 close to the U-shaped frame B510 is smaller than the size of the moving block 509 away from the U-shaped frame B510, so as to facilitate the restriction of the movement of the U-shaped frame B510.

[0029] The present invention sets a clamping assembly 5, places the gearbox housing between the fixed plate 502 and the movable plate 505, and then rotates the screw rod 506 by a wrench, so that the screw rod 506 rotates in the movable groove B503 through the rotating shaft. Since the screw rod 506 is threadedly connected with the movable block 504, the movable block 504 slides in the movable groove B503, causing the movable plate 505 to move toward the fixed plate 502 until the inner end face of one of the U-shaped frames C511 contacts the surface of the gearbox housing. At this time, one end of the rotating plate 512 on the U-shaped frame C511 is connected to the U through the rotating shaft A. The U-shaped frame C511 rotates, causing the other end of the rotating plate 512 on the U-shaped frame C511 to rotate with the U-shaped frame B510 through the rotating shaft B, so that the U-shaped frame B510 slides in the moving groove 508 through the moving block 509, causing the adjacent U-shaped frame C511 to move away from the fixed plate 502 or the movable plate 505 until the inner end surface of the remaining U-shaped frame C511 contacts the surface of the gearbox housing. At this time, the gearbox housing is clamped. Since the surface of the gearbox housing is mostly irregular in shape, the clamping assembly 5 can easily and stably clamp the gearbox housing.

[0030] The working principle of the present invention is as follows: when in use, first, the gearbox housing is placed between the fixed plate 502 and the movable plate 505, and then the screw rod 506 is rotated by a wrench, so that the screw rod 506 rotates in the movable groove B503 through the rotating shaft. Since the screw rod 506 is threadedly connected with the movable block 504, the movable block 504 slides in the movable groove B503, causing the movable plate 505 to move toward the fixed plate 502 until the inner end surface of one of the U-shaped frames C511 contacts the surface of the gearbox housing. At this time, the U-shaped frame C511 is in contact with the gearbox housing. One end of the rotating plate 512 on 511 rotates with respect to the U-shaped frame C511 via the rotating axis A, causing the other end of the rotating plate 512 on the U-shaped frame C511 to rotate with the U-shaped frame B510 via the rotating axis B. This causes the U-shaped frame B510 to slide in the moving groove 508 via the moving block 509, causing the adjacent U-shaped frame C511 to move away from the fixed plate 502 or the movable plate 505 until the inner end surface of the remaining U-shaped frame C511 contacts the surface of the gearbox housing. At this point, the gearbox housing is clamped. Then, according to the position where the gearbox housing needs to be drilled, the toggle plate 405 is pressed downward to make the toggle plate 405 slide downward in the open groove 404, so that the movable cylinder 402 slides downward in the movable groove A401, and the spring 403 is forced to shrink until the bottom surface of the toggle plate 405 contacts the bottom wall of the open groove 404. At this time, the sliding cylinder 302 is moved to drive the transmission rod 204 and the drill bit body 104 to slide in the sliding groove 301, so that the limiting sleeve 304 slides in the limiting groove 303, and the guide block 411 slides in the guide groove 410, so that the outer end spherical surface of the connecting block 407 is disengaged from the stabilizing groove 408 and squeezes the inner wall of the limiting groove 303, so that the connecting block 407 slides in the connecting groove 406 until the connection is completed. The inner spherical surface of the connecting block 407 moves into the receiving groove 409. At this time, the outer spherical surface of the connecting block 407 contacts the inner wall of the limiting groove 303. After the drill body 104 moves to the appropriate position, the toggle plate 405 is released. Under the elastic force of the spring 403, the movable cylinder 402 slides upward in the movable groove A401, causing the toggle plate 405 to slide upward in the open groove 404, causing the inner wall of the receiving groove 409 to squeeze the inner spherical surface of the connecting block 407, causing the connecting block 407 to slide in the connecting groove 406 until the inner spherical surface of the connecting block 407 contacts the outer circumferential surface of the movable cylinder 402. At this time, the outer spherical surface of the connecting block 407 is plugged into the stabilizing groove 408, so that the position of the sliding cylinder 302 is fixed in the sliding groove 301. Subsequently, the spindle motor 103 is started, so that the output shaft of the spindle motor 103 drives the driving gear 203 to rotate, so that the driving gear 203 engages and rotates with multiple driven gears 205, so that the driven gear 205 drives the transmission rod 204 to rotate, and the transmission rod 204 drives the drill body 104 through the tool holder to drill the gearbox housing. After the drilling is completed, the gearbox housing can be removed.
