DETAILED DESCRIPTION
[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments, but they are not intended to limit the present invention.
[0022] Embodiment of the present invention: a deburring device for an internal gear, such as Figure 1-3 As shown, it includes: a machine platform 1, three groups of roller assemblies 2, a driving gear 5 driven by a motor, a burr removal mechanism 6 for grinding and deburring, and a limiting roller structure.
[0023] During use, the internal gear product part 100 is placed on the three groups of roller assemblies 2, and the internal gear product part 100 is meshed with the driving gear 5. When the driving gear 5 rotates, it can drive the internal gear product part 100 to rotate on the three groups of roller assemblies 1. The outer periphery of the internal gear product part 100 is supported by the limiting roller structure to avoid the internal gear product part 100 from being in a horizontal position during the rotation process, ensuring that it can rotate stably. The burr removal mechanism 6 can grind and deburr the inner gear ring of the internal gear product part 100. The overall deburring process requires little manual participation and the deburring operation is performed automatically. One operator can take care of multiple devices, which greatly improves efficiency and has good practicality. In addition, it is not easy to omit and ensure the deburring effect.
[0024] The burr removal mechanism 6 is located between the No. 2 roller assembly 22 and the No. 3 roller assembly 23. Specifically, the burr removal mechanism 6 is more inclined to the inside than the fixed limit roller group 3, and is adapted to the structure of the internal gear product 100. The burr removal mechanism 6 includes a deburring motor 64. The output end of the deburring motor 64 is connected to the input end of the transmission box 63. The upper wire brush wheel 61 and the lower wire brush wheel 62 are respectively installed on the two output ends of the transmission box 63. When performing the deburring operation, the deburring motor 64 operates normally and drives the upper wire brush wheel 61 and the lower wire brush wheel 62 to rotate at the same time through the transmission of the transmission box 63. The upper wire brush wheel 61 and the lower wire brush wheel 62 can grind and remove burrs on the surface of the inner tooth block of the internal gear product 100 and the tooth grooves between adjacent tooth blocks.
[0025] The design of the transmission case 63 enables the upper wire brush wheel 61 and the lower wire brush wheel 62 to rotate simultaneously, which is more space-friendly and can achieve deburring with only one deburring motor 64. The rotating upper wire brush wheel 61 and the lower wire brush wheel 62 deburr the inner gear ring of the internal gear product 100. In this embodiment, two wire brush wheels, the upper wire brush wheel 61 and the lower wire brush wheel 62, are provided to simultaneously grind and remove burrs from both ends of the inner gear block of the internal gear product 100, eliminating the need for flipping, further improving deburring efficiency.
[0026] The transmission box 63 is mounted on the adjustment end of the multi-axis manipulator 11. The multi-axis manipulator 11 is fixedly mounted on the machine platform 1 and rotates and adjusts the upper wire brush wheel 61 and the lower wire brush wheel 62 to deburr the tooth end surface of the internal gear product 100. In this embodiment, the multi-axis manipulator 11 is a six-axis manipulator with a six-degree-of-freedom robotic arm. This design enables the manipulator to move in three axial directions (X, Y, and Z) and rotations around these three axes (commonly known as roll, pitch, and yaw). This design allows the six-axis manipulator to be connected to other equipment when not connected to the transmission box 63, thereby completing complex operational tasks such as welding, assembly, handling, and spraying.
[0027] Three groups of roller assemblies 2 are provided on the top surface of the machine 1, namely roller assembly No. 1 21, roller assembly No. 2 22 and roller assembly No. 3 23. The rollers in the roller assembly 2 support the internal gear product 100, and the internal gear product 100 can also rotate on the rollers. In order to ensure the stable rotation of the internal gear product 100, a limiting roller structure needs to be designed on the outside of the internal gear product 100.
[0028] The No. 1 roller assembly 21, the No. 2 roller assembly 22 and the No. 3 roller assembly 23 are distributed in an equiangular circle, and the angle between adjacent roller assemblies 2 is 120°. Figure 1 The No. 1 roller assembly 21, the No. 2 roller assembly 22 and the No. 3 roller assembly 23 are arranged reasonably and are installed on the table of the machine 1 with bolts. The space between the two roller assemblies 2 can also be used to install other components.
[0029] The drive gear 5 is located between the No. 1 roller assembly 21 and the No. 3 roller assembly 23. A drive shaft 51 is provided on the drive gear 5. The drive shaft 51 extends through the table top of the machine 1 and into the interior of the machine 1. The through end of the drive shaft 51 is connected to the drive motor via a transmission assembly. Referring to the accompanying drawings, the drive shaft 51 is mounted on the table top of the machine 1 via a bearing. The top of the drive shaft 51 is mounted with a drive gear 5. After the drive gear 5 is driven to rotate by the drive motor, it can be transmitted between the meshing tooth block structure and the internal gear product 100, thereby ensuring that the internal gear product 100 can rotate. The drive gear 5 meshes with the internal gear product 100, and the rotating drive gear 5 drives the internal gear product 100 to rotate on the rollers. In combination with the structural characteristics of the internal gear product 100, the use of the drive gear 5 for driving ensures stable driving and is less likely to cause damage to the internal gear product 100.
[0030] The limiting roller structure includes a fixed limiting roller group 3 and a pressing limiting roller group 4 respectively arranged on both sides of the machine 1. The fixed limiting roller group 3 and the pressing limiting roller group 4 are symmetrically distributed with the center of the three groups of roller assemblies 2 as the center of the circle. The fixed limiting roller group 3 and the pressing limiting roller group 4 each include two roller bodies. Specifically, the two roller bodies of the fixed limiting roller group 3 are installed on both sides of the No. 2 roller assembly 22. The circumferential wall of the fixed limiting roller group 3 is in contact with the outer wall of the internal gear product 100. The fixed limiting roller group 3 is fixedly installed on the machine 1. During the rotation of the internal gear product 100, the outer wall of the internal gear product 100 is always in contact with the circumferential wall of the fixed limiting roller group 3 to ensure that the internal gear product 100 rotates stably.
[0031] The clamping and limiting roller group 4 includes two limiting roller bodies, which are arranged on the outside of the driving gear 5. The clamping and limiting roller group 4 can move. During the movement toward the driving gear 5, it can ensure that the internal gear product part 100 is finally engaged with the driving gear 5. After engagement, the outer wall of the other end of the internal gear product part 100 is always in contact with the fixed limiting roller group 3. The internal gear product part 100 is limited by four points (the clamping and limiting roller group 4 and the fixed limiting roller group 3), thereby ensuring that the internal gear product part 100 can only rotate on its own when driven by the driving gear 5.
[0032] The two limiting rollers of the clamping and limiting roller set 4 are respectively mounted on a slide 8, which is located in a chute 7 and connected to the branch end of a tensioning frame 9. The tensioning frame 9 is also connected to the output end of a tensioning cylinder 10, which is mounted on the inner surface of the machine table 1 via a mounting base. The tensioning cylinder 10 is used to simultaneously pull the two limiting rollers of the clamping and limiting roller set 4 toward the drive gear 5. This not only simplifies control but also ensures the synchronous movement of the two limiting rollers, thereby achieving automatic positioning of the internal gear product 100.
[0033] The pull frame 9 is a Y-shaped structure, and is connected to the output end of the tensioning cylinder 10. An opening is formed between the two branch ends of the pull frame 9 and the slider 8 to avoid the driving shaft 51. Figure 3 The branch design of the pull frame 9 can also avoid the driving shaft 51, and the spatial distribution is reasonable to ensure the stable operation of the device.
[0034] The deburring process is described in detail below: First, the internal gear product 100 is placed on the roller assembly 2 by a handling robot, handling equipment or manual labor. It is necessary to ensure that the driving gear 5 and the burr removal mechanism 6 are located on the inner side of the internal gear product 100, and the fixed limiting roller group 3 is located on the outer side of the internal gear product 100. Then the tensioning cylinder 10 is driven, and the tensioning cylinder 10 is shortened to drive the pulling frame 9 to move, so that the clamping limiting roller group 4 at the branch end of the pulling frame 9 moves toward the driving gear 5. The moving clamping limiting roller group 4 can also position the internal gear product 100 until the inner teeth of the internal gear product 100 are engaged with the driving gear 5, and the outer side of the other end of the internal gear product 100 is in contact with the fixed limiting roller group 3.
[0035] Then start the drive motor and drive the drive gear 5 to rotate through transmission. Because the drive gear 5 is engaged with the internal gear product part 100, and the outside of the internal gear product part 100 is also limited by the fixed limiting roller group 3 and the clamping limiting roller group 4, the internal gear product part 100 can only rotate on the roller assembly 2.
[0036] During the rotation of the internal gear product 100, the removal motor 64 can be turned on. The removal motor 64 is driven by the transmission box 63 to drive the upper wire brush wheel 61 and the lower wire brush wheel 62 to rotate simultaneously, and the internal gear product 100 is polished and deburred until the internal gear product 100 rotates one circle and all polishing is completed.
[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
