Description

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0021] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] The following is for reference. Figures 1 to 6 The embodiment of the present invention, a CNC programmable flexible brush deburring machine for aluminum wheels, is described in conjunction with specific examples.

[0023] A CNC programmable flexible brushing and deburring machine for aluminum wheels includes a support and axial motion assembly 1, a rotary motion assembly 2, a radial motion assembly 3, a split brush 4, an aluminum wheel 5, and a flexible clamping assembly 6; a first servo motor 7, a support column 8, a base plate 9, a second reducer 10, a lead screw nut 11, a lead screw 12, a first reducer 13, and a third reducer 14; a linear bearing 15, a second servo motor 16, an axial movement plate 17, a connecting flange 18, a conductive slip ring 19, and a primary rotary spindle 20. Synchronous belt 21, synchronous pulley 22; third servo motor 23, fixed plate 24, bearing 25, secondary rotary spindle 26, bearing outer ring 27, second gear 28, third gear 29, guide rail slider 30, first gear 31, first rack 32, outer shell 33; equipment upper plate 34, receiving cylinder 35, receiving tray 36, pneumatic gripper 37, first gripper fixing plate 38, fourth gear 39, second rack 40, second gripper fixing plate 41, clamping cylinder 42, material feeding recognition photoelectric sensor 43.

[0024] A flexible clamping assembly 6 is installed on the top of the equipment. The clamping assembly uses a cylinder as its power source and a gear and rack system to achieve power transmission, ensuring that the two pneumatic grippers 37 driven by the first gripper fixing plate 38 and the other two pneumatic grippers 37 driven by the second gripper fixing plate 41 move synchronously to achieve centered clamping of the wheel to be processed. The flexible clamping assembly is equipped with a receiving tray 36, which is controlled by two cylinders respectively, and is used to place the wheel when not in operation, facilitating loading and unloading operations. Two diagonally placed material placement identification photoelectric sensors 43 are used to detect whether a wheel is present at the processing station. The working process is as follows: In the initial state, the clamping cylinder 42 retracts and the pneumatic gripper 37 is in the released state; the receiving cylinder 35 extends and, together with the feeding mechanism, places the aluminum wheel 5 on the receiving tray 36; after the wheel is placed in place, the feeding recognition photoelectric 43 detects the aluminum wheel 5 and transmits a signal to the equipment. At this time, the clamping cylinder 42 extends and the pneumatic gripper 37 clamps the aluminum wheel 5. Then the receiving cylinder 35 retracts and the receiving tray 36 retracts, ready for processing.

[0025] A radial motion component 3 is installed in the middle of the device. This component is controlled by rotational and axial motion and is connected to four separate brushes 4, independently achieving radial motion control. This allows for the transmission of three motions, enabling the brushing of the aluminum wheel 5. The radial motion is powered by a third servo motor 23, which transmits power to a first gear 31. The first gear 31 is circumferentially distributed and meshes with four second gears 28. Each second gear 28 is connected to a third gear 29 via a main shaft. Each third gear 29 meshes with a first rack 32, which is fixed to a guide rail slider 30. Finally, the guide rail slider 30 connects to the separate brushes 4, achieving radial motion. This component uses a three-stage gear transmission to convert the rotational motion of the motor into linear radial motion of the separate brushes 4. All transmission components are encapsulated within the housing 33. The power transmission of the first-stage rotating main shaft 20 is achieved by connecting a second-stage rotating main shaft 26 to a fixed plate 24. The outer ring of the bearing 27 is connected to the radial motion component 3 and fixed to the axial moving plate 17, achieving axial motion transmission.

[0026] A rotary motion component 2 is installed at the lower part of the equipment. This part is controlled by axial motion and can independently realize rotary motion control. The second servo motor 16 is used as the power source. The power is transmitted to the synchronous pulley 22, and then to the first-stage rotary spindle 20 via the synchronous belt 21. The power is then transmitted to the radial motion component 3. The two sides of the axial moving plate 17 are connected to the lead screw nut 11. The axial motion is realized by the helical transmission of the lead screw 12. Linear bearings 15 are set at the four corners, which together with the support column 8 undertake the guiding role of axial motion.

[0027] The bottom of the equipment is equipped with a support and axial motion assembly 1. This part uses the first servo motor 7 as the power source, which transmits power to the first reducer 13. The second reducer 10 and the third reducer 14 are connected to the two sides respectively, and the reverse direction is realized through them. The second reducer 10 and the third reducer 14 transmit power to the lead screw 12, which then drives the screw nut 11 to realize the axial movement of the rotary motion assembly 2, the radial motion assembly 3, and the split brush 4. The bottom plate 9 of the equipment is equipped with four support columns 8 at the four corners to undertake the guiding role during the movement and the overall support role of the equipment.

[0028] The working process of a CNC programmable flexible brushing deburring machine for aluminum wheels is as follows: In the initial state of the equipment, the pneumatic gripper 37 is in the retracted state, the receiving plate 36 is in the extended state, and the split brush 4 is in the initial position below the receiving plate 36 under the action of the support and axial movement component 1; the aluminum wheel 5 is placed on the receiving plate 36 through the loading and unloading mechanism. After the feeding identification photoelectric 43 identifies the aluminum wheel 5, it sends a signal to the clamping cylinder 42, and the equipment performs a clamping action. The pneumatic gripper 37 contacts the lower rim of the aluminum wheel 5 and clamps it, and releases a signal to the receiving cylinder 35. Then the receiving plate 36 retracts, ready to start the brushing deburring work. After receiving the start signal, the second servo motor 16 increases its speed to a preset value, driving the primary rotating spindle 20 and the secondary rotating spindle 26 via the synchronous pulley 22 and synchronous belt 21, thereby driving the radial movement component 3 and the split brush 4 to rotate together. After the speed reaches a preset threshold, the first servo motor 7 receives a signal and starts working, realizing the reversal of motion through the second reducer 10 and the third reducer 14, and realizing the overall lifting of the rotating motion component 2 and the radial movement component 3 through the screw drive of the lead screw nut 11. After rising to a preset height, the third servo motor 23 starts working, realizing the radial movement of the split brush 4 through the three-stage gear transmission. After the forward rotation achieves the expected effect, the rotating motion component 2 and the radial movement component 3 move down. After the rotation stops, the second servo motor 16 starts to reverse, and then the support and axial motion component 1 and the radial movement component 3 repeat the above process in reverse. After the forward and reverse rotation is completed, the support and axial motion component 1, the radial motion component 3, and the rotary motion component 2 all return to their original positions. Then, the receiving tray 36 extends, the pneumatic gripper 37 retracts, and the aluminum wheel 5 is released onto the receiving tray 36, where the unloading mechanism performs the unloading and transfer.

[0029] In the above processing, the rotational, radial, and axial movements of the equipment can be independently controlled and coupled to achieve processing for different back shapes of the aluminum wheel 5. For example, the split brush 4 can stay in the initial position for a few seconds and only perform rotational movement; or the split brush 4 can perform radial movement while following the height of the window to perform axial movement to achieve conformal processing; correspondingly, the rotational movement should be continuous, as it is the main action of the brush bristles.

[0031] The aluminum wheel CNC programmable flexible brush deburring machine disclosed in this invention achieves burr removal for wheels of different sizes and shapes by decoupling the brush deburring action and adopting an innovative approach of independent control of separate brushes. It can process the back cavity shape according to the requirements, meet the zero-change of brushes and fixtures on site, improve production efficiency, significantly improve the processing effect, and reduce the risk of wheel corrosion.
