Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of thin-walled bearing processing, in particular to a feeding and discharging device based on thin-walled precision bearing grinding. BACKGROUND

[0002] Thin-walled bearings are a special type of bearing suitable for high-speed, high-precision, and high-environmental requirement equipment such as aerospace, robotics, and automation equipment. Thin-walled bearings are widely used in various industries due to their lightweight and high reliability characteristics, and with the continuous development of technology, the thin-walled bearing industry is also evolving and growing.

[0003] Currently, the production technology of high-precision bearings still lags behind international advanced levels, especially thin-walled bearings in high-speed, high-precision equipment have very high requirements for size and geometric shape, which requires enterprises to continuously improve their technology to have advanced precision manufacturing technology. Thin-walled bearings are mainly 17, 18, and 19 series products, which are characterized by thin wall thickness and narrow width, resulting in poor overall rigidity and difficulty in processing due to deformation. Therefore, deformation needs to be considered in the grinding process of thin-walled bearings, and process control is needed to reduce deformation to ensure that the performance of finished bearings meets design requirements.

[0004] Currently, the feeding and discharging actions of the machine tool during outer ring raceway processing are not reasonable, as shown in the drawings, the processed product is a bearing outer ring, the main working principle is: the ring falls from the material channel to the initial position of the ring as shown, then the pushing cylinder pushes the ring into the normal processing area, i.e. Figure 1 the ring grinding position, after the ring grinding is completed, the pushing cylinder pushes the ring out of the grinding area from the discharging direction and into the discharging channel, which has the following defects: Figure 1 1. The cylinder needs to overcome the spring tension during feeding and discharging, and this force is directly loaded onto the outer diameter of the ring by the cylinder, then transmitted to the pressure roller to complete the action. Since the ring is relatively thin, the stress will cause the ring to deform, resulting in poor roundness of the outer diameter, and since the outer diameter roundness is the reference, it will lead to an increase in the probability of process parameter deviation in subsequent processes based on the outer diameter as the reference, and a decrease in product pass rate.

[0005]

[0006] ​2. The main function of the pressure roller is to stop the material. During operation, the stop block is frequently subjected to force, and the spring is subjected to impact force when it rebounds. Since the position of the stop block is adjustable, it is easy for the stop block to loosen and shift after repeated impact forces. When the position shifts, the pressure roller will be subjected to a third clamping force in addition to the two supports and magnetism when it contacts the bearing ring during grinding. At this time, the bearing ring is subjected to uneven force, which will lead to changes in eccentricity, unstable clamping, grinding scrap, increased repair frequency, and reduced grinding efficiency.

[0007] 3. The existing structure has unstable feeding. Because the material channel is close to the end face, if the end face support is energized and the ring is not pushed into the correct area, the ring will be stuck. If the grinding head enters at this time, at best the grinding wheel will break and the ring will be scrapped. If the equipment door is not closed at this time, it will threaten the personal safety of the staff.

[0008] 4. The end face of the ring near the grinding head does not have a safety baffle. If uncontrollable events such as demagnetization or incomplete feeding occur, there is a risk of the ring flying off the grid, which threatens the personal safety of the staff.

[0009] Based on the above issues, the tooling components for loading and unloading need to be redesigned and reinstalled to solve these problems, improve product qualification rate, and reduce production costs.
