[0026] Embodiment 1

[0027] Refer to Figure 1 、 Figure 2 And Figure 3 For the first embodiment of the present invention, this embodiment provides a hub processing and drilling device, including a machine platform 1. Four support columns 2 are fixedly connected to the upper surface of the machine platform 1. A limit frame 3 is inlaid inside the machine platform 1. A fixing component 4 is arranged above the limit frame 3. The top ends of the support columns 2 are fixedly connected to a machine top plate 5. The outer surface of the support column 2 is slidably connected to a machine plate 6. A fixing frame 7 is fixedly connected to the lower surface of the machine plate 6. A protection component 8 is arranged on the lower surface of the fixing frame 7;

[0028] The fixing component 4 includes a bidirectional lead screw 401 inserted into the limit frame 3. Two limit blocks 402 are movably connected to the outer surface of the bidirectional lead screw 401. A placement plate 403 is fixedly connected to the upper surface of the machine platform 1. T-shaped push blocks 404 are fixedly connected to the upper surfaces of the two limit blocks 402. A groove 408 is opened inside the T-shaped push block 404. A unidirectional lead screw 405 is inserted into the groove 408.

[0029] Specifically, one end of the bidirectional lead screw 401 passing through the limit frame 3 is fixedly connected to a hand wheel. The end of the bidirectional lead screw 401 far from the hand wheel is movably connected to the inner wall of the limit frame 3 through a bearing seat. A clamping plate 406 is threadedly connected to the outer surface of the unidirectional lead screw 405. An arc-shaped rubber abutting block 407 is fixedly connected to the side surface of the T-shaped push block 404. One end of the unidirectional lead screw 405 passing through the T-shaped push block 404 is fixedly connected to a hand crank. The outer surface of the unidirectional lead screw 405 is movably connected to the inner wall of the T-shaped push block 404 through a bearing, and the end of the unidirectional lead screw 405 far from the hand crank is movably connected to the bottom end of the inner wall of the T-shaped push block 404 through a bearing seat.

[0030] Further, when it is necessary to drill holes in the hub, the staff need to place the hub on the placing plate 403, and then rotate the handwheel to drive the bidirectional lead screw 401, so that the two limit blocks 402 movably connected to the outer surface of the bidirectional lead screw 401 move, and at the same time, the T-shaped push block 404 above the two limit blocks 402 and the arc-shaped rubber abutting block 407 fixedly connected to the side of the T-shaped push block 404 are mutually clamped. Then rotate the hand crank to drive the unidirectional lead screw 405, so that the clamping plate 406 movably connected to the outer surface of the unidirectional lead screw 405 can move up and down. Therefore, the hub can be fixed and clamped to avoid inaccurate positioning of the hub during hole drilling due to the vibration of the device.

[0031] Embodiment 2

[0032] Refer to Figure 2 、 Figure 4 and Figure 5 This is the second embodiment of the present utility model. This embodiment is based on the previous embodiment.

[0033] The protection component 8 includes a fixed frame plate 801 fixedly connected to the lower surface of the fixed frame 7. A reset spring 802 is fixedly connected to the inner top end of the fixed frame plate 801. The bottom end of the reset spring 802 is fixedly connected to a movable plate 803. A rotating shaft 804 is connected through the inside of the fixed frame 7.

[0034] Specifically, an oil path tool shank 805 is movably connected to the outer surface of the rotating shaft 804. An internal coolant drill bit 806 is movably connected to the bottom end of the oil path tool shank 805. A drive motor 9 is arranged inside the fixed frame 7, and the output end of the drive motor 9 is fixedly connected to the rotating shaft 804. An air pump 10 is arranged between the machine top plate 5 and the machine plate 6. The outer surface of the support column 2 is slidably connected to the inner wall of the machine plate 6.

Support legs are fixedly connected to the lower surface of the machine table 1, and the number of the support legs is four.

[0035] Further, subsequently start the drive motor 9 arranged inside the fixed frame 7, and at the same time start the hydraulic pump 10 arranged between the machine top plate 5 and the machine plate 6, so as to realize the downward hydraulic pressure of the machine plate 6 in cooperation with the support column 2, and the machine plate 6 and the support column 2 are slidably connected. Therefore, the internal cooling drill bit 806 installed below the oil path tool handle 805 contacts the hub placed on the placement plate 403 for drilling operations. At the same time, the fixed frame plate 801 below the machine plate 6 can retract when it contacts the surface of the hub through the return spring 802 fixedly connected inside the fixed frame plate 801 and the movable plate 803 at the lower end of the return spring 802, realizing the treatment of iron filings, avoiding scratches on the surface of the hub caused by iron filings, increasing the practicability of the device, and the water inlet of the oil path tool handle 805 connected to the outer surface of the rotating shaft 804 is connected to the coolant tank 12 through a high-pressure water pipe. Since the oil path tool handle 805 and the internal cooling drill bit 806 are prior arts, no further elaboration is made here.

[0036] Working principle: When it is necessary to drill the hub, the staff needs to place the hub on the placement plate 403, and then rotate the handwheel to drive the bidirectional lead screw 401, so that the two limit blocks 402 movably connected to the outer surface of the bidirectional lead screw 401 move, and at the same time, the T-shaped push blocks 404 above the two limit blocks 402 and the arc-shaped rubber abutting blocks 407 fixedly connected to the sides of the T-shaped push blocks 404 are mutually clamped. Then rotate the hand crank to drive the unidirectional lead screw 405, so that the clamping plate 406 movably connected to the outer surface of the unidirectional lead screw 405 can move up and down, so as to fix and clamp the hub, avoiding inaccurate positioning of the hub drilling due to the vibration of the device. Subsequently, start the drive motor 9 arranged inside the fixed frame 7, and at the same time start the hydraulic pump 10 arranged between the machine top plate 5 and the machine plate 6, so as to realize the downward hydraulic pressure of the machine plate 6 in cooperation with the support column 2, and the machine plate 6 and the support column 2 are slidably connected. Therefore, the internal cooling drill bit 806 installed below the oil path tool handle 805 contacts the hub placed on the placement plate 403 for drilling operations. At the same time, the fixed frame plate 801 below the machine plate 6 can retract when it contacts the surface of the hub through the return spring 802 fixedly connected inside the fixed frame plate 801 and the movable plate 803 at the lower end of the return spring 802, realizing the treatment of iron filings, avoiding scratches on the surface of the hub caused by iron filings, increasing the practicability of the device, and the water inlet of the oil path tool handle 805 connected to the outer surface of the rotating shaft 804 is connected to the coolant tank 12 through a high-pressure water pipe. Since the oil path tool handle 805 and the internal cooling drill bit 806 are prior arts, no further elaboration is made here.
