[0002] As these high-tech industries continue to improve their product quality and technical requirements, traditional grinding equipment and processes have gradually revealed their limitations. The shortcomings of traditional grinding processes in terms of accuracy and efficiency can no longer meet the needs of modern industry for high-precision and high-performance mechanical parts. Therefore, super-precision grinding technology came into being, and with its excellent grinding accuracy and efficiency, it has become an indispensable part of modern manufacturing. In key mechanical components such as roller bearings, the accuracy of the roller has a vital impact on the performance of the entire mechanical system. As a component that bears the load when the bearing is running, the roller is a very critical part of the roller bearing. Its manufacturing quality is directly related to the working performance of the bearing, such as rotation accuracy, vibration, noise and flexibility, which are key factors affecting the service life of the bearing. Therefore, improving the grinding accuracy of the roller is not only a need to improve product quality and technical level, but also an important way to meet specific application requirements and enhance market competitiveness. In particular, it plays a pivotal role in promoting the production of high-precision mechanical parts, such as in the aerospace industry, large-scale integrated circuits, laser technology, and precision instrument manufacturing.

[0003] In the process of grinding rollers, technicians in the field of ultra-precision grinding try to achieve synchronous rotation of the rollers while the grinding head is grinding.

[0020] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to further illustrate the present invention.

[0021] First, combine Figures 1 to 3 The roller superfinishing spindle device according to the embodiment of the utility model is widely used in industrial manufacturing and other scenes such as precision mechanical parts processing with high-precision grinding and polishing. In this embodiment, the grinding roller is taken as an example for explanation.

[0022] like Figures 1 to 3 As shown, the roller superfinishing spindle device of the embodiment of the utility model is used to position at a preset work station and drive the roller to be ground to rotate, and includes: a pair of rotating shafts 1, a rotating body 2 and an adjusting component 3.

[0023] Specifically, Figures 1 to 3 As shown, a pair of rotating shafts 1 are arranged in parallel, and an external driver drives the pair of rotating shafts 1 to rotate. The pair of rotating shafts 1 arranged in parallel are the basic structure of the device. They are responsible for transmitting the rotating power through the external driver and providing a stable driving source for the rotation of the roller; a rotating body 2 is arranged at the end of each rotating shaft 1, and a pair of rotating bodies 2 are arranged on the same side of the pair of rotating shafts 1. The rotating shaft 1 drives the rotating body 2 to rotate. The rotating body 2 arranged at the end of each rotating shaft 1 directly contacts the roller to be ground, and the roller is driven to rotate by the circumferential friction force through the rotation of the rotating shaft 1. The design of the rotating body 2 uses a structure to synchronously realize the positioning and smooth rotation of the roller, so as to achieve the preset accuracy of super-fine grinding and improve the processing efficiency; the adjustment component 3 adjusts the spacing between the pair of rotating bodies 2 to adapt to rollers of different diameters. When processing the roller to be ground, the closest distance between the outer edges of the pair of rotating bodies 2 is less than the diameter of the roller to be ground. The design of the entire device fully considers the stability and accuracy requirements during the processing process. By accurately controlling the rotation of the rotating shaft 1 and the adjustment of the adjustment component 3, the stability and grinding accuracy of the roller during the processing are ensured.

[0024] Preferably, if Figures 1 to 3 As shown, when processing the roller to be ground, the roller is located on the same side of a pair of rotating bodies 2. In the same cross-section, the angle 4 formed by the line segment connecting the centers of the pair of rotating bodies 2 and the line segment connecting the center of the roller to the center of one of the rotating bodies 2 is an acute angle, which helps to achieve stable positioning during the grinding process and realize a more uniform distribution of grinding force.

[0025] Preferably, if Figure 2 As shown, the acute angle is 8 to 20 degrees, which effectively avoids the problem of local excessive wear or insufficient grinding caused by uneven grinding force, and further improves the grinding accuracy.

[0026] Preferably, the acute angle is 11 to 13 degrees, which has a better processing effect and further improves the grinding accuracy and processing quality, making the processing quality of the roller more stable and reliable.

[0027] Preferably, the surface roughness of the rotating body 2 is not greater than Ra0.2, which reduces the friction resistance between the rotating body 2 and the roller, making the roller rotate more smoothly, while also reducing the wear of the rotating body 2 and making it more controllable.

[0028] Preferably, if Figure 1 , 3As shown, the adjustment component 3 includes a pair of bases, a pair of rotating shafts 1 are respectively arranged on a pair of bases, and a pair of bases are arranged on slide rails or ball screws. The slide rails or ball screws are introduced as the basic structure of the adjustment component 3 and are equipped with bases, so that the adjustment of the spacing of the rotating body 2 is more accurate and convenient.

[0029] Preferably, if Figure 1 As shown, an adjustment handle 31 is provided on the outer side of any base, and the adjustment handle 31 drives the base to move along the extension direction of the slide rail or the ball screw, thereby improving the adaptability and operational convenience of the device and facilitating the operator to manually adjust the movement of the base along the slide rail or the ball screw, thereby realizing fast and accurate adjustment of the spacing of the rotating body 2.

[0030] Preferably, if Figures 1 to 3 As shown, it also includes a lifting component 5, which can push the roller away from the pair of rotating shafts 1. The introduction of the lifting component 5 allows the roller to be easily separated from the rotating body 2 after the processing is completed, thereby improving the convenience of workpiece replacement.

[0031] Preferably, if Figure 3 As shown, the lifting assembly 5 includes a lifting frame 51, and a clamping claw 52 is provided at one end of the lifting frame 51 close to the roller, and a cylinder 53 is provided at one end of the lifting frame 51 away from the roller. The cylinder 53 drives the lifting frame 51 to move, and the clamping claw 52 can fix or detach the two ends of the roller. The clamping claw 52 of the lifting assembly 5 can fix or detach the two ends of the roller, and the movement of the lifting frame 51 is driven by the cylinder 53, thereby realizing automatic lifting and detachment of the roller. The clamping claw 52 allows the roller to move stably, and the clamping at both ends does not affect the grinding accuracy of the roller.

[0032] During use, through automatic control or operator, according to the size specifications of this batch of rollers, the spacing between a pair of rotating bodies 2 is adjusted by adjusting component 3 to adapt to the diameter of the roller to be ground. The roller to be ground is placed between the rotating bodies 2 to ensure that the roller is located on the same side of a pair of rotating bodies 2. Start the external drive, a pair of parallel rotating shafts 1 provide rotational power through the external drive, and the rotating body 2 on the rotating shaft 1 contacts and clamps the roller to be ground. The rotating body 2 rotates driven by the rotating shaft 1, thereby driving the roller to rotate. During the grinding process, according to the processing requirements, the spacing between the rotating bodies 2 can be further fine-tuned by adjusting the handle 31 to ensure the grinding effect. After the processing is completed, the roller is lifted and disengaged from the rotating body 2 by the lifting component 5 to facilitate the next round of processing.

[0033] Above, refer to Figures 1 to 3The invention describes a roller ultra-finishing grinding spindle device according to an embodiment of the utility model. Through a pair of parallel rotating shafts 1 and an adjustable rotating body 2, the roller to be ground is quickly positioned, stably clamped and efficiently rotated. The device can quickly and accurately position the roller to be ground and provide it with stable rotational power. This design ensures the continuity and stability of the roller during the processing, effectively avoiding the time loss required for clamping, positioning and driving rotation of the fixture in the traditional method, thereby greatly improving the processing efficiency. During the grinding process, the synchronous rotation of the rotating shaft 1 and the rotating body 2 ensures that the relative motion between the roller and the grinding head is always in the best state, thereby achieving high-precision and high-efficiency grinding processing. This synchronous relative motion grinding technology meets the needs of modern manufacturing industry for high-precision processing, not only greatly improves the processing efficiency, but also significantly improves the grinding accuracy through the synchronous relative motion grinding technology.
