Description

Technical Field

[0001] This utility model relates to the technical field of deburring devices, specifically a deburring device for processing precision mechanical parts. Background Technology

[0002] Machining refers to the process of changing the shape, size, or properties of a workpiece using mechanical equipment. Based on the processing method, it can be divided into cutting and pressure processing. Precision machining is a process of changing the shape, size, or properties of a workpiece using machining machinery. For precision mechanical parts, such as common ring-shaped parts, deburring devices are often used to remove burrs from their surfaces. However, existing deburring devices typically require first clamping and fixing the part with a jig, then deburring the outer side of the part, and finally deburring the inner side. Since deburring cannot be performed at the clamping position, additional deburring is required at the clamping position, making the operation cumbersome and impractical. Therefore, a deburring device for machining precision mechanical parts is proposed. Utility Model Content

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a deburring device for machining precision mechanical parts, which has the following advantages:

[0014] This deburring device for precision machining of mechanical parts uses a servo motor to drive a worm gear, which in turn drives a threaded rod. During rotation, the threaded rod, via two threaded sleeves, moves two first moving blocks, two connecting blocks, two second moving blocks, and two second arc-shaped clamping plates in opposite directions. The two second arc-shaped clamping plates press against the inner wall of the annular part, clamping and fixing it from the inside. This allows for deburring of the outer side of the annular part. When deburring the inner side of the annular part is required, the servo motor is activated to rotate in the opposite direction, thus driving the threaded rod. Reverse rotation: During this rotation, the threaded rod drives the two first moving blocks, two first arc-shaped clamps, two connecting blocks, two second moving blocks, and two second arc-shaped clamps to move relative to each other via the two threaded sleeves. This allows the two first arc-shaped clamps to clamp and fix the outer side of the annular part, while the two second arc-shaped clamps move to the center of the annular part. This avoids affecting the deburring operation on the inner side of the annular part. By adjusting the clamping position, the deburring operation on both the outer and inner sides of the annular part can be completed in one operation without additional steps, thus improving processing efficiency and making it more convenient for users.

The two first movable blocks 18 are located on the left and right sides of the annular part 4, respectively.

[0025] A second drive assembly 23 is fixedly installed on the outer right end of the threaded rod 15, with one end movably connected to the bottom of the processing table 1 and the other end fixedly connected to the right side of the right support plate 2. The second drive assembly 23 includes a servo motor 231. The servo motor 231 located below the threaded rod 15 is fixedly installed on the right side of the right support plate 2. The model of the servo motor 231 can be MR-J2S-10A. The output shaft of the servo motor 231 is fixedly installed with a worm gear 232 located behind the threaded rod 15 and movably connected to the bottom of the processing table 1 at one end. A third bearing located on the right side of the right support plate 2 is fixedly installed on the bottom of the processing table 1. The worm gear 232 is rotatably connected to the bottom of the processing table 1 through the third bearing. A worm wheel 233 located on the right side of the right support plate 2 and meshing with the worm gear 232 at one end is fixedly installed on the outer side of the threaded rod 15.

[0026] All electrical components mentioned in the text are connected to an external controller and 220V AC mains power, and the external controller can be a conventional known device such as a computer that is used for control.

[0027] In use, the servo motor 231 can be started by an external controller to drive the worm gear 232 to rotate, which in turn drives the threaded rod 15 to rotate via the worm wheel 233. During the rotation of the threaded rod 15, the two threaded sleeves 17 drive the two first moving blocks 18, the two connecting blocks 20, the two second moving blocks 21, and the two second arc-shaped clamping plates 22 to move in opposite directions. The two second arc-shaped clamping plates 22 compress the inner wall of the annular part 4, thereby clamping and fixing the annular part 4 from the inside. The second drive motor 142 can be started to drive the rotating shaft 143 and friction roller 144 to rotate, and the first drive motor 91 can be started to drive the drive bevel gear 92 to rotate, which in turn drives the mounting shaft 8, mounting block 10 and deburring assembly 14 to rotate as a whole through the driven bevel gear 93, thereby performing deburring operation on the outer circumference of the annular part 4. When it is necessary to deburr the inner side of the annular part 4, the two first electric telescopic rods 6 can be started by the external controller to drive the moving plate 5 and the deburring assembly 14 to move as a whole. The device moves upward, and then the servo motor 231 is activated to rotate in the opposite direction, thereby driving the threaded rod 15 to rotate in the opposite direction. During the rotation of the threaded rod 15, it will drive the two first moving blocks 18, the two first arc-shaped clamping plates 19, the two connecting blocks 20, the two second moving blocks 21, and the two second arc-shaped clamping plates 22 to move relative to each other through the two threaded sleeves 17. This allows the two first arc-shaped clamping plates 19 to clamp and fix the outer side of the annular part 4, and move the two second arc-shaped clamping plates 22 to the center position of the annular part 4, thereby avoiding affecting the deburring operation on the inner side of the annular part 4. Then, the second electric telescopic rod 13 can be activated to drive the slider 12 and the deburring assembly 14 to move to the right as a whole. Then, the two first electric telescopic rods 6 are activated again to drive the moving plate 5 and the deburring assembly 14 to move downward, so that the friction roller 144 contacts the left side of the inner wall of the annular part 4. Finally, the second drive motor 142 and the first drive motor 91 are activated again to perform the deburring operation on the inner circumference of the annular part 4.

[0028] In summary, this deburring device for precision mechanical parts machining uses a servo motor 231 to drive the worm gear 232 to rotate, which in turn drives the threaded rod 15 to rotate via the worm wheel 233. During rotation, the threaded rod 15 drives two first moving blocks 18, two connecting blocks 20, two second moving blocks 21, and two second arc-shaped clamping plates 22 to move in opposite directions via two threaded sleeves 17. The two second arc-shaped clamping plates 22 press against the inner wall of the annular part 4, thus clamping and fixing the annular part 4 from the inside. This allows for deburring of the outer side of the annular part 4. When deburring of the inner side of the annular part 4 is required, the servo motor 231 can be activated to rotate in the opposite direction, driving the threaded rod 15 to rotate in the opposite direction. During this rotation, the threaded rod 15 drives the two first moving blocks 18, two first arc-shaped clamping plates 19, and two connecting blocks 20 via the two threaded sleeves 17. The two second moving blocks 21 and the two second arc-shaped clamping plates 22 move relative to each other, thereby clamping and fixing the outer side of the annular part 4 through the two first arc-shaped clamping plates 19, and moving the two second arc-shaped clamping plates 22 to the center position of the annular part 4, thus avoiding affecting the deburring operation on the inner side of the annular part 4. By adjusting the clamping position, the deburring operation on the outer and inner sides of the annular part 4 can be completed in one operation without additional operation, thereby improving the processing efficiency and facilitating the use of the user. This solves the problem that in the actual use of existing deburring devices, it is usually necessary to first use a clamp to clamp and fix the part, then use the deburring device to deburr the outer side of the part, and then deburr the inner side of the part. However, since the clamping position cannot be deburred, additional deburring operation is required at the clamping position, which makes the operation more cumbersome and inconvenient to use.
