[0002] Honing is a finishing method that uses an oilstone (also called a honing stick) embedded in a honing head to apply a certain pressure to the workpiece surface. The honing tool or the workpiece simultaneously performs relative rotation and axial linear reciprocating movement to remove extremely small allowances on the workpiece, which can achieve high precision and high surface quality on the workpiece machined surface.

[0003] The applicant submitted a patent application on the same day for the independently developed slender rod external cylindrical honing head. When in use, two sets of drive mechanisms are required to drive the main body of the honing head and the drive disk to rotate respectively. Due to the limited space on the honing machine, installing the honing head and two separate drive mechanisms will take up more space on the honing machine and cause the structure of the honing machine to be complicated, which is inconvenient for subsequent maintenance of the honing machine. Therefore, the applicant specially designed a drive device. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions in the utility model will be further described below with reference to the drawings and embodiments.

[0021] like Figures 1 to 3 As shown, the embodiment of the present invention proposes a slender rod external cylindrical honing head driving device, which is used in conjunction with the slender rod external cylindrical honing head proposed by the applicant in another patent application to drive the main body and driving disk in the honing head to rotate.

[0022] Please refer to Figure 1 and Figure 2 The slender rod external cylindrical honing head driving device includes a box body 1, a rotatable main shaft 2 and a rotatable inner shaft 3 are provided in the box body 1, the main shaft 2 and the inner shaft 3 are coaxially arranged and the main shaft 2 is provided with a through slot 24 for accommodating the inner shaft 3, one end of the inner shaft 3 extends out of the box body 1 and the end of the inner shaft 3 extending out of the box body 1 is transmission-connected with a transmission shaft 31, a first driving gear 32 is provided on the transmission shaft 31 and the first driving gear 32 is transmission-connected with the driving disk in the honing head, one end of the main shaft 2 extends out of the box body 1 and the end of the main shaft 2 extending out of the box body 1 is transmission-connected with a transmission cylinder 21, the transmission cylinder 21 is sleeved on the transmission shaft 31 and is coaxially arranged with the transmission shaft 31, the A second driving gear 22 is provided on the transmission cylinder 21 and the second driving gear 22 is transmission-connected to the main body in the honing head. The second driving gear 22 and the first driving gear 32 are spaced apart along the axial direction of the transmission shaft 31. The housing 1 is also provided with a first driving member 4 and a second driving member 5. The first driving member 4 is transmission-connected to the main shaft 2. The power output by the first driving member 4 is transmitted by the main shaft 2 to the transmission cylinder 21 and drives the second driving gear 22 to rotate, thereby driving the main body to rotate. The second driving member 5 is transmission-connected to the inner shaft 3. The power output by the second driving member 5 is transmitted by the inner shaft 3 to the transmission shaft 31 and drives the first driving gear 32 to rotate, thereby driving the drive disk to rotate.

[0023] Specifically, the working process of the driving device for the external cylindrical honing head of the slender rod provided in this embodiment is as follows: The transmission shaft 31 and the transmission cylinder 21 are respectively installed into the honing head, and the first driving gear 32 is drivingly connected to the driving disk, and the second gear is drivingly connected to the main body. After the workpiece to be processed passes through the honing head, the first driving member 4 and the second driving member 5 are respectively started. The power output by the first driving member 4 is transmitted from the main shaft 2 to the transmission cylinder 21 and drives the second driving gear 22 to rotate, causing the main body to rotate. The power output by the second driving member 5 is transmitted from the inner shaft 3 to the transmission shaft 31 and drives the first driving gear 32 to rotate, causing the driving disk to rotate. At this time, the speed at which the first driving member 4 drives the main shaft 2 to rotate is not equal to the speed at which the second driving member 5 drives the inner shaft 3 to rotate, so that the driving disk generates transmission relative to the main body and drives the honing bars in the honing head to approach the workpiece until they are in close contact with the workpiece surface. After the honing bars are in contact with the workpiece, the speed of the main shaft 2 is adjusted by the first driving member 4 and the speed of the inner shaft 3 is adjusted by the second driving member 5 to make the two equal. At this time, the rotation of the main body drives the honing bars to hone the surface of the workpiece. After the processing is completed, the speed of the main shaft 2 is adjusted by the first driving member 4 and the speed of the inner shaft 3 is adjusted by the second driving member 5 to make the two unequal. At this time, the driving disk generates transmission relative to the main body and makes the honing bars in the honing head move away from the workpiece until they are separated from the workpiece surface, and then the processed workpiece can be taken out from the honing head. The driving device for the external cylindrical honing head of the slender rod provided in this embodiment has a compact structure, effectively simplifies the overall structure of the equipment, is beneficial to reducing the space occupied by the driving device for the external cylindrical honing head of the slender rod on the equipment and optimizing the equipment layout.

The first universal joint 6 provided between the inner shaft 3 and the transmission shaft 31 is used to transmit the power of the inner shaft 3 to the transmission shaft 31 to make the transmission shaft 31 rotate synchronously with the inner shaft 3, and ensure that when the position of the honing head changes and the inner shaft 3 and the transmission shaft 31 are not coaxial, the power of the inner shaft 3 can still be smoothly transmitted to the transmission shaft 31, ensuring that the transmission shaft 31 rotates smoothly under the drive of the second driving member 5.

[0025] In this embodiment, the first universal joint 6 includes a connecting rod 61 and connecting heads 62 disposed at opposite ends of the connecting rod 61. First connecting rings 63 are rotatably connected to the connecting heads 62 respectively. One of the first connecting rings 63 is sleeved on the inner shaft 3, and the other first connecting ring 63 is sleeved on the transmission shaft 31. The rotation axes of the two first connecting rings 63 on the connecting heads 62 are perpendicular to each other. The first universal joint 6 is composed of the connecting rod 61, the connecting heads 62 respectively disposed at opposite ends of the connecting rod 61, and the first connecting rings 63 rotatably connected to the connecting heads 62. One of the two first connecting rings 63 is sleeved on the inner shaft 3, and the other is sleeved on the transmission shaft 31. While transmitting the inner shaft 3 and the transmission shaft 31, the power of the inner shaft 3 can be transmitted to the transmission shaft 31 when the position of the honing head changes through the rotation of the first connecting ring 63 relative to the connecting head 62, which is beneficial to improving the reliability of the driving device for the outer circle honing head of the slender rod.

The second universal joint 7 includes the flange 71 and the connecting flanges 72 are provided at opposite ends of the flange 71 respectively. Second connecting rings 73 are rotatably connected to the connecting flanges 72 respectively. The flange 71, the connecting flanges 72 and the second connecting rings 73 enclose a cavity 74 for accommodating the first universal joint 6 to prevent the first universal joint 6 from colliding with the second universal joint 7 during operation. The two second connecting rings 73 cooperate with the main shaft 2 and the transmission cylinder 21 respectively to make the transmission connection between the main shaft 2 and the transmission cylinder 21 stable and reliable, and change the transmission direction of the power of the main shaft 2 through the rotation of the second connecting rings 73 relative to the connecting flanges 72, ensuring that the transmission cylinder 21 can rotate smoothly under the drive of the external cylindrical honing head driving device of the slender rod when the position of the honing head changes.

The second driving shaft 52 extends into the box body 1, and a second driving gear 53 is provided on the second driving shaft 52. When the second driving shaft 52 rotates driven by the second motor 51, it drives the second driving gear 53 to rotate, and transmits power to the inner shaft 3 through the cooperation of the second driving gear 53 and the second transmission gear 33, ensuring that the inner shaft 3 rotates stably under the drive of the second motor 51.

[0031] Specifically, a support plate 12 is provided in the box body 1.
