Description

Technical Field

[0001] The invention relates to the technical field of bearing steel ball processing, in particular to a bearing steel ball grinding processing device. Background Art

[0002] Bearing steel balls are steel balls installed inside bearings. In the process of bearing steel ball processing, grinding is a very important step, which has the following functions: 1. Meet precision requirements: Bearing steel balls are usually required to have very high precision and surface quality. Grinding is an effective method to make the surface of steel balls smooth and accurate to the micron level, ensuring that they meet strict size and shape requirements; 2. Improve surface quality: Through grinding, surface roughness, oxide scale and other defects can be removed, the surface quality of bearing steel balls can be improved, and the impact of surface defects on friction and wear can be reduced; 3. Improve roundness and reduce size tolerance: Grinding can ensure that the roundness and size tolerance of bearing steel balls meet the specified standards, ensuring the interchangeability and matching of each steel ball during use; 4. Improve surface hardness: Through grinding, the hardness of the surface layer of bearing steel balls can be increased, and its wear resistance and service life can be improved; 5. Optimize bearing performance: Grinding can optimize the subtle shape of the surface of bearing steel balls, which helps to reduce friction and energy loss during rolling, thereby improving the operation efficiency of bearings.

[0003] Bearing steel balls are generally initially ground using a rotary drum grinder. During grinding, diamond powder and bearing steel balls are placed into the rotary drum grinder at the same time according to the proportion, and then cooling water is injected. The extremely high hardness and grinding performance of the diamond powder are used to efficiently grind the bearing steel balls.

[0004] Although the existing method has a grinding effect, the rotary drum grinder only causes the diamond powder and the bearing steel ball to produce high-throw motion. Since the rotary drum rotates slowly, the inertial upward movement distance of the diamond powder and the bearing steel ball is small, so the movement amplitude of the diamond powder and the bearing steel ball is small. In addition, generally, more diamond powder will be precipitated at the bottom of the rotary drum grinder, which has a certain buffering effect and will also have an adverse effect on the grinding of the bearing steel ball. It takes a long time to ensure the grinding effect of the bearing steel ball, which is not conducive to improving the grinding production efficiency of the bearing steel ball. At the same time, the rotary drum is in a rotating state when working, and the bearing steel ball cannot be loaded and unloaded in the middle. Each time the bearing steel ball is taken out, the diamond powder needs to be discharged together, which is not convenient to use. Summary of the invention

The plurality of guide rods 26 located on the same mounting plate 28 are commonly connected to a third connecting plate 27 at both upper and lower ends. The third connecting plate 27 is fixedly connected to the inner wall of the shell 1. A wave-shaped curved pipe frame 24 is symmetrically arranged between the left and right mounting plates 28. The upper and lower ends of the wave-shaped curved pipe frame 24 are both straight pipes. The straight pipes of the wave-shaped curved pipe frame 24 are fixedly connected to the mounting plate 28 through a second connecting plate 25.

The movable pin 334 moves in the mouth frame 331 to drive the sieve bucket 31 to swing back and forth around the hinge position between it and the shell 1, so as to achieve the vibration effect of the sieve bucket 31, avoiding the problem of bearing steel balls blocking the fine holes and making it difficult to completely separate the diamond powder.

[0045] See also Figure 1 and Figure 5 The shaking assembly 22 includes a first rack 222 fixedly connected to the left side surface of the left mounting plate 28, and a second mounting shaft 227 and a first mounting shaft 225 are symmetrically connected to the left side wall of the shell 1 corresponding to the position of the first rack 222, and the second mounting shaft 227 is fixedly connected to the second gear 226 and the first half gear 221 at one end of the second mounting shaft 227 located inside the shell 1, and the first gear 224 and the second half gear 223 are fixedly connected to the first mounting shaft 225 at one end inside the shell 1, the first gear 224 and the second gear 226 are meshed and connected, and the first half gear 221 and the second half gear 223 are alternately meshed and connected with the first rack 222.
