Description

Technical Field

[0001] This utility model belongs to the technical field of roller cleaning machines, specifically relating to a hollow roller cleaning machine top tooling. Background Technology

[0002] In the bearing manufacturing industry, the cleaning effect of large rollers directly affects the service reliability of high-precision bearings. These rollers typically need to be axially fixed through center bores and cleaned while rotating. Current mainstream roller cleaning equipment is limited by the tight fit between the center and the roller contact surface. Traditional spray or immersion cleaning methods are difficult to effectively remove complex contaminants inside the center bore. Hard particles such as turning shavings and grinding particles easily embed in the oil film on the center bore wall, while the gelatinous dirt formed by the carbonization of oil-based coolant residue after heat treatment stubbornly adheres to the bore wall. If the center area cannot be fully penetrated by the cleaning medium during the cleaning process, these residues may interfere with the roundness and surface roughness measurement data of the rollers in subsequent testing, leading to a false acceptance rate. During the assembly stage, contaminants will cause deviations in the fit clearance between the rollers and the bearing rings, accelerating abnormal wear of the raceway during operation. More seriously, the abrasive particles that are not removed continue to scrape the contact surface under high load operation, significantly shortening the bearing fatigue life. Existing technologies mainly rely on increasing external spray pressure or multi-axis rotary immersion cleaning to improve this. However, high-pressure spraying creates turbulent dead zones in the closed top hole, while rotary immersion cleaning creates a centrifugal force barrier due to the inertia of the large roller mass, which hinders the penetration of the cleaning fluid into the core area of ​​the hole. In order to solve the systematic precision degradation caused by the blind spot in the top cleaning area, a hollow roller cleaning machine top tooling is proposed. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a hollow roller cleaning machine top tooling, which has a simple structure, is easy to use, eliminates cleaning blind spots, and cleans the rollers more thoroughly.

[0004] The technical solution adopted by this utility model is: a hollow roller cleaning machine top tooling, including a fixing part, the fixing part including a fixing platform and a fixing column set on the bottom surface of the fixing platform. The fixing platform and the fixing column are both circular and concentrically arranged. The top surface of the fixing platform is provided with a main body part, which is cylindrical and concentrically arranged with the fixing platform. A conical positioning part is connected above the main body part. The bottom surface of the positioning part is the same size as the top surface of the main body part. Overflow holes are provided at the top and around the top of the positioning part. Hollow cavities are provided inside the fixing part, the main body part and the positioning part. The hollow cavities penetrate the positioning part, the main body part and the fixing part from top to bottom. The top of the hollow cavity is connected to the overflow hole and the hollow cavity penetrates the bottom of the fixing part.

[0005] The top of the positioning part is provided with a circular top overflow hole with rounded corners. Multiple radial overflow holes are evenly distributed on the side wall of the positioning part near the top overflow hole.

[0006] Fixing holes are provided on both sides of the upper surface of the fixed platform.

[0007] The number of radial overflow holes is 2-6, and the diameter of each hole is 2-5mm.

[0008] The cross-section of the hollow cavity is circular.

[0009] The fixing part, the main body part and the positioning part are integrally formed.

[0010] The main body is made of high-strength alloy steel.

[0011] The beneficial effects of this utility model are as follows:

[0012] This utility model has a simple structure and is easy to use. The main body, as the base support of the tip, is made of high-strength alloy steel to ensure that it has sufficient strength and rigidity to withstand various forces during the cleaning process. The rounded corner design at the top of the positioning part can prevent the roller from being punctured during the positioning process, reducing the overall volume and weight of the tip and lowering the risk of damage caused by collisions during operation. At the same time, the designed overflow hole position can ensure that when the roller is in the positioning position, the overflow hole leaves half of the margin and will not completely penetrate into the tip hole of the roller. The hollow cavity design facilitates the delivery of cleaning oil, making the tip hole of the roller cleaner. Attached Figure Description
