[0002] Gears are indispensable parts in various mechanical equipment and play an extremely important role, especially in gear transmission. During gear production, it is often necessary to grind and polish the gear surface to make it burr-free. General grinding and polishing devices can only operate on one side, and then the other side needs to be manually flipped over and operated again. This method is relatively cumbersome and troublesome, and greatly prolongs the operation time of gear grinding and polishing.

[0003] In order to solve the above technical problems, Chinese patent CN218639233U, a gear grinder points out that by setting a pulling cross bar and an annular rotating plate to drive the stabilizing bar and the clamping bevel bar to flip the gear, the gear flipping operation is made simpler and more convenient, avoiding manual flipping of the gear, making the gear grinding operation simpler and more convenient, helping to grind the gear more efficiently, and further improving people's convenience in gear processing. The above patent can indeed save a lot of time in this way, and can realize double-sided grinding of the gear through the flipping operation, but this method still has certain technical problems. The above patent needs to be flipped before the grinding operation can be performed, and the effect of simultaneous grinding of both sides at one time cannot be achieved. Therefore, there are shortcomings to a certain extent, and it is impossible to speed up the grinding operation of the gear surface more effectively.

[0004] Therefore, in order to achieve simultaneous grinding of both sides of the gear, significantly speed up the grinding / polishing operation, and shorten the grinding and polishing operation time, a grinding and polishing device for gear processing is proposed, which further shortens the grinding time of the gear on the basis of the existing technology.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example

[0025] See also Figure 1-6 The utility model provides the following technical solutions: a grinding and polishing device for gear processing, comprising a device main body, a conveying device for conveying a gear ring is provided on the device main body, a grinding device for realizing double-sided grinding and a polishing device for realizing double-sided polishing are installed on the device main body, a clamping structure that can rotatably clamp the gear is installed on the device main body between the grinding device and the polishing device, the grinding device is installed on the upper end face of the device main body in front of the clamping structure, and the polishing device is located on the upper end face of the device main body in the rear of the clamping structure, and the clamping structure can realize 360° rotation, and the grinding device comprises a first mounting frame 3 mounted on the upper end of the device main body, and a first servo motor 4 is installed on the upper end of the first mounting frame 3. A bearing seat is also installed at the upper end of the body, and a first threaded shaft 5 is installed on the inner ring of the bearing seat. The first threaded shaft 5 is connected to the output end of the first servo motor 4, and two groups of first mounting plates 6 are provided on the surface of the first threaded shaft 5. A second servo motor 7 is installed on the surface of each group of first mounting plates 6, and a grinding wheel is installed at the output end of the second servo motor 7. The polishing device includes a second mounting frame 8 installed at the upper end of the device body, a third servo motor 9 is installed at the upper end of the second mounting frame 8, and the output end of the third servo motor 9 is connected to the second threaded shaft 10. A second mounting plate 11 is installed on the surface of the second threaded shaft 10, a fourth servo motor 12 is installed on the surface of the second mounting plate 11, and a polishing wheel 13 is installed at the output end of the fourth servo motor 12.

[0026] In this embodiment, the specific working principle is as follows: this device takes the grinding device as an example (the grinding device is similar in structure to the polishing device), and drives the grinding wheel to grind both sides of the gear clamped by the clamping structure through the action of two sets of second servo motors 7. When the clamping structure rotates to between the two sets of first mounting plates 6, the first servo motor 4 is started to drive the first threaded shaft 5 to rotate. Since the threaded connections of the two sets of first mounting plates 6 and the first threaded shaft 5 are opposite, the two sets of first mounting plates 6 move toward the middle at the same time, thereby driving the grinding wheel to move toward the middle to grind the gear surface. The polished gear is clamped The structure rotates 180° and rotates the polishing device to polish the surface of the gear through the polishing wheel 13, thereby achieving the simultaneous grinding and polishing of the upper and lower side surfaces of the gear, thereby solving the problem that the existing device for grinding the surface of the gear cannot achieve simultaneous grinding of both sides. The two groups of second servo motors 7 located on the first mounting plate 6 and the two groups of fourth servo motors 12 located on the second mounting plate 11 have opposite directions. In this way, when working on the gear, it can prevent the gear from detaching from the handle 26 under the action of the same steering force due to the same direction of rotation.

[0027] How the clamping structure realizes rotation can be found in Figure 2 It can be seen that the clamping structure includes a motor 28 installed on the inner side of the upper end of the device body, and a mounting body 21 is also installed on the device body. A ball bearing 22 is installed on the inner side of the mounting body 21, and a movable column 23 is installed on the inner ring of the ball bearing 22. The lower end of the movable column 23 is connected to the output end of the motor 28. A fixed body 24 is installed on the surface of the movable column 23, and a pneumatic gripper 25 is installed on the side of the fixed body 24. A gripping handle 26 is installed on the outer end of the pneumatic gripper 25. The initial position is as shown in FIG. Figure 1 As shown, the clamping structure is located on the conveying device on the right side of the workbench 2. When the gear is conveyed to the appropriate position, the gear is clamped by the gripping handle 26, and then the movable column 23 is driven to rotate by the motor 28. The specific angle of rotation, such as 90° and 180°, can be achieved through the control of the PLC. After the clamping structure grasps the gear, it is first rotated 90° to the grinding device for grinding, and then rotated 180° clockwise to the polishing device for polishing, and finally rotated 90° counterclockwise to the conveying device on the left side of the workbench 2 for transmission.

[0028] According to the above, in order to facilitate the gripping of the gear by the gripping handle 26 to prevent the gear from loosening, and secondly to prevent the gear from rotating due to the rotational force during grinding and polishing, please refer to Figure 2 and Figure 5 It can be seen that the inner side surface of the gripping handle 26 is provided with a serrated protrusion, which can produce a locking effect with the tooth block of the gear, thereby effectively clamping the gear.

[0029] In order to prevent the surface of the handle 26 from being damaged during grinding and polishing, the height of the handle 26 is located in the middle of the height of the gear placed on the conveyor. That is to say, when the handle 26 clamps the gear, the handle 26 is clamped in the middle of the gear surface, so that there is a distance between the upper and lower ends of the gear, so that there will be no wear and tear on the surface of the handle 26 due to grinding and polishing.

[0030] In order to make the first mounting plate 6 and the second mounting plate 11 move smoothly and prevent collision with the mounting frame, please refer to Figure 6 It can be seen that auxiliary rollers 27 are installed on the surfaces of the first mounting plate 6 and the second mounting plate 11. The auxiliary roller 27 located on the surface of the first threaded shaft 5 contacts the inner side of the first mounting frame 3, and the auxiliary roller 27 located on the surface of the second mounting plate 11 contacts the inner side of the second mounting frame 8. Through the action of the auxiliary rollers 27, not only the movement of the mounting plate is facilitated, but also a certain supporting role can be played, so that the mounting plate maintains the stability of movement and reduces the load on the threaded shaft.

[0031] The transmission device in this device can be found in Figure 1 and Figure 4 It can be seen that the conveying device includes a mounting frame 14 installed at the upper end of the device body, a conveying frame is installed on the mounting frame 14, a conveying motor 15 is installed at the right end of the frame, the output end of the conveying motor 15 is connected to a roller, and a conveyor belt 16 is provided on the surface of the roller. The conveying device is symmetrically installed on the device body.

[0032] In order to facilitate the control of the device, please refer to Figure 1 It can be seen that a control structure is also installed on the side of the device body, and the control structure includes a fixed plate 17 installed on the side of the device body, a column 18 is installed on the upper end of the fixed plate 17, a movable rod 19 is installed on the upper end of the column 18, and a control box 20 is installed on the end of the movable rod 19.

[0033] See Figure 1 It can be seen that the device body includes a base 1 , a workbench 2 is installed on the upper end of the base 1 , and the first mounting frame 3 , the second mounting frame 8 , the mounting frame 14 , and the mounting body 21 are all installed on the upper end surface of the workbench 2 .

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
