Description

Technical Field

[0001] This utility model relates to the field of mandrel processing technology, specifically to a grinding device for mandrel processing. Background Technology

[0002] A mandrel is a crucial mechanical component, primarily used to support rotating parts and withstand bending moments, but not to transmit torque. It has wide applications in the mechanical field and is an important component connecting rotating parts. Mandrel machining is a complex process involving multiple key steps, including cutting, grinding, drilling, and polishing.

[0003] Currently, existing grinding devices for mandrel processing mostly grind the mandrel wall surface by rotating the grinding wheel. However, the grinding structure has a relatively simple function. In order to achieve comprehensive processing, it is necessary to drive the mandrel to rotate, which can easily affect the stability of the mandrel during grinding and result in poor performance. Utility Model Content

[0004] The purpose of this invention is to provide a grinding device for mandrel processing. It comprises a fixed frame, fixed rings, movable rings, support rings, and a grinding mechanism. The grinding mechanism consists of a connecting frame, a U-shaped frame, and a grinding wheel. After the mandrel passes between the two fixed rings, the distance between the two three-jaw chucks can be adjusted to fix the end of the mandrel onto the chucks. The grinding wheel can then be controlled to press against the outer wall of the mandrel. With the rotation of the grinding wheel, the mandrel's surface can be ground. Then, with the cooperation of the drive assembly, the two support rings can drive the grinding mechanism to rotate, allowing the grinding wheel to grind the mandrel 360 degrees. Furthermore, the fixed frame drives the grinding wheel to reciprocate in a straight line, effectively achieving comprehensive grinding of the mandrel. The device is easy to operate, provides stable and reliable grinding, and has good performance, thus overcoming the aforementioned shortcomings in the technology.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model provides, for example Figures 1-4 A grinding device for mandrel machining is shown, comprising:

[0024] The processing table 1 has two fixed stops 2 on its top side, and each stop 2 is equipped with a clamping assembly.

[0025] The clamping assembly includes a first cylinder 3 fixedly connected to the outside of the retainer 2. The output end of the first cylinder 3 passes through the retainer 2 and is connected to a three-jaw chuck 4 facing the center of the fixing ring 7. Based on this, the mandrel can be passed between the two fixing rings 7 and the end of the mandrel can be fixed on the three-jaw chuck 4. The first cylinder 3 can drive the three-jaw chuck 4 to move, thereby quickly adjusting the distance between the two three-jaw chucks 4 so that the two three-jaw chucks 4 can be clamped at both ends of the mandrel respectively, thus effectively fixing it according to the length of the mandrel.

[0026] A fixed frame 6 is movably mounted on the top side of the processing table 1 between two clamping assemblies. Fixed rings 7 are symmetrically arranged at both ends of the top of the fixed frame 6. Movable rings 17 are rotatably mounted on the inner side of each of the two fixed rings 7. A sliding assembly is provided between the inner side of the movable ring 17 and the fixed ring 7. A support ring 8 is fixed on the outer side of the movable ring 17. A grinding mechanism is provided between the two support rings 8. A drive assembly is provided on the fixed frame 6, and the drive assembly is used to drive the support rings 8 to rotate.

[0027] A linear guide rail 5 is provided in the middle of the top side of the processing table 1. The top side of the linear guide rail 5 is connected to the fixed frame 6 through a slide.

[0028] The polishing mechanism includes a connecting frame 11 fixedly connected between two support rings 8. A second cylinder 12 is fixedly connected to the outside of the connecting frame 11. The output end of the second cylinder 12 extends into the connecting frame 11 and is provided with a U-shaped frame 13. A first motor 15 is fixed to one end of the U-shaped frame 13, and a polishing wheel 14 is rotatably connected to the inside of the U-shaped frame 13 through a rotating shaft. The output end of the first motor 15 is connected to the polishing wheel 14.

[0029] In use, the mandrel can be passed between the two fixing rings 7, and the three-jaw chuck 4 can be moved by the first cylinder 3. The distance between the two three-jaw chucks 4 can be quickly adjusted so that the end of the mandrel can be fixed on the three-jaw chuck 4. Then the second cylinder 12 can be started, so that the second cylinder 12 drives the grinding wheel 14 to move through the U-shaped frame 13, so that the grinding wheel 14 presses against the outer wall of the mandrel. The grinding wheel 14 is driven to rotate by the first motor 15, so that the grinding wheel 14 can grind the wall surface of the mandrel.

[0030] By activating the drive assembly, the drive assembly can drive the movable ring 17 to rotate on the fixed ring 7. Then, the movable ring 17 can drive the support ring 8 to rotate, causing the two support rings 8 to drive the grinding mechanism to rotate. This allows the grinding mechanism to perform 360-degree grinding on the mandrel. Furthermore, the fixed frame 6 can be moved via the linear guide rail 5, which in turn drives the grinding wheel 14 to reciprocate along a straight line via the two fixed rings 7. This effectively achieves comprehensive grinding of the mandrel, making the operation convenient, the grinding stable and reliable, and the performance good.

The output end of the second motor 19 is connected to a gear 18, and a toothed ring 16 that meshes with the gear 18 is fixed to the outside of one of the movable rings 17.

[0033] By starting the second motor 19, the second motor 19 can drive the gear 18 to rotate, and then the gear 18 can drive the meshing gear ring 16 to move, so that the gear ring 16 drives the movable ring 17 to rotate. The movable ring 17 can drive the T-shaped slider 9 to slide along the T-shaped slide groove 10, so that the movable ring 17 can drive the support ring 8 to rotate on the fixed ring 7, and then the two support rings 8 can drive the grinding mechanism to rotate.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
