Description

Technical Field

[0001] The utility model relates to a bearing anti-scratch support device, belonging to the technical field of bearing processing. Background Art

[0002] During the machining process of bearing rings (such as outer ring end face grinding, outer diameter grinding, and groove grinding), the bearing rings are mounted on a machine tool and driven by the machine tool to rotate during the grinding process. During this process, the outer diameter of the bearing rings needs to be supported. For larger products, due to the heavy weight of the bearing rings themselves and the sliding fit between the support material and the outer diameter of the bearing rings, the outer diameter surface of the bearing rings is easily scratched by the support material (such as carbide or ceramic), which not only affects the appearance but also, in serious cases, affects the quality of the product. Utility Model Content

[0003] The purpose of this utility model is to address the deficiencies of the above-mentioned prior art and provide a bearing anti-scratch support device, which changes the sliding fit between the support component and the bearing ring into a rolling fit, effectively improving the problem of scratches on the ring support surface caused by the support component and realizing markless support.

[0004] The technical solution of the utility model is as follows:

[0005] The anti-scratch bearing support device is characterized in that it includes an upper support assembly and a lower support assembly, and the upper and lower support assemblies respectively include: a support wheel and a support body, and the support wheel is rotatably assembled on one end of the corresponding support body; the two support bodies are arranged at a certain angle so that the two support wheels are tangent to the outer cylindrical surface of the bearing ring and form a rolling fit therewith.

[0006] In the above scheme, the bearing ring is radially fixed under the action of the upper and lower supporting components that form an angle β with each other. The upper and lower supporting wheels can rotate freely relative to the supporting body and the bearing ring. The relative sliding between the bearing ring and the supporting component is converted into relative rotation and rolling. The supporting wheel uses the same bearing steel material as the bearing ring, which effectively prevents the supporting component from scratching the bearing surface of the bearing ring.

[0007] Furthermore, the support wheel is connected to the support body via a support wheel bearing and a support connecting shaft. The support wheel is mounted on the outer ring of the support wheel bearing, and the support connecting shaft is mounted on the inner ring of the support wheel bearing, which is also mounted on the support body. In the upper and lower support assemblies, the support wheel rotates relative to the support body via the support wheel bearing, and also rotates relative to the bearing ring, thereby preventing the support from scratching the bearing surface of the bearing ring.

[0008] Furthermore, the end of the supporting body is provided with a first side plate and a second side plate arranged at intervals and in parallel, the first side plate is provided with two circular holes and a center hole, and the second side plate is provided with a square hole; the tail end of the supporting connecting shaft is provided with a square plate, the center of its front end is provided with a positioning column, and the front end is also provided with two threaded holes; the supporting connecting shaft is located between the first side plate and the second side plate, the square plate is located in the square hole of the second side plate, and the positioning column is located in the center hole of the first side plate; two screws pass through the two circular holes of the first side plate respectively and are screwed into the two threaded holes of the supporting connecting shaft.

[0009] In the above scheme, a square hole and two circular holes are designed on the two side panels of the supporting body respectively. The circular hole is assembled with the positioning column of the supporting connecting shaft, and the square hole is assembled with the square plate of the supporting connecting shaft. The two different holes cooperate with the supporting connecting shaft to ensure that the supporting connecting shaft and the supporting body are firmly fastened to prevent the supporting connecting shaft from rotating.

[0010] Furthermore, the support body is provided with two rows of parallel mounting holes, each row of mounting holes is composed of a number of spaced and evenly distributed mounting holes. The design of multiple mounting holes can adapt to the problem of non-uniform installation positions of different models of machine tools.

[0011] Furthermore, it also includes a support seat, a support connecting seat, an adjusting bolt, and a locking nut; the support seat is arc-shaped, and its surface is provided with T-slots arranged in an arc shape, and the two supporting bodies are respectively assembled with the T-slots of the support seat. The support connecting seat is provided with a stepped waist-shaped hole, and the locking nut is located in the stepped waist-shaped hole and is restrained on the stepped surface of the stepped waist-shaped hole; the head of the adjusting bolt is located in the T-slot, and its rod extends and connects to the locking nut, connecting the support connecting seat and the support seat into one body, and the support connecting seat and the corresponding supporting body are connected by bolts.

[0012] The above scheme is easy to install and disassemble. The mutual installation of the support body and the support seat is achieved by connecting the support seat. The installation of the upper and lower supports is achieved by cooperating with the arc-shaped T-slot on the support connecting seat and the support seat, and the angle β between the upper and lower support components can be adjusted arbitrarily as needed. During installation: first, the head of the adjusting bolt is inserted from the T-slot at the end of the support seat. The head of the adjusting bolt can slide relative to the T-slot to adjust the position of the support body in the circumferential direction of the support seat; then, the locking nut is installed in the stepped waist-shaped hole of the support connecting seat and is limited to the step surface of the stepped waist-shaped hole. The locking nut can slide along the stepped waist-shaped hole to adjust the position of the support body in the radial direction of the support seat; then, the adjusting bolt and the locking nut are threadedly connected and locked, thereby fixing the support connecting seat and the support seat; finally, the support body is fixedly connected to the corresponding support connecting seat by bolts. A through groove is provided in the middle of the support body, and the through groove corresponds to the stepped waist-shaped hole of the support connecting seat to facilitate the adjustment of the bolt and the locking nut.

[0013] The utility model is a new anti-scratch support device for bearing ring processing. Through the support wheel that can rotate relative to the bearing ring supporting surface, the support component is effectively transformed from a sliding fit relative to the bearing ring to a rotating rolling fit, preventing the support from scratching the bearing ring supporting surface. The utility model is simple to manufacture and low in cost, can well achieve the anti-scratch purpose, and largely guarantees the processing accuracy of the product.
