Description

Technical Field

[0001] The utility model belongs to the technical field of bearing processing equipment and relates to a fine grinding and blanking structure for inner and outer rings of a bearing. Background Art

[0002] Ball bearings are mainly composed of four basic components: balls, inner rings, outer rings and retainers, also called cages. Ball bearings can be used in various machines and equipment with rotating parts, so their application range is very wide.

[0003] The inner and outer rings of the bearing are annular, and they need to be finely processed by grinding equipment before assembly to ensure that the friction coefficient of the internal or surface grooves meets the standard, and finally the inner and outer ring components of the bearing that meet the requirements are assembled to realize the product. At present, after the inner and outer rings of the bearing are processed, they are uniformly output to the material frame container placed below through the unloading track. For example, the patent with the authorization announcement number CN206570367U discloses a material receiving device after the spheroidization of the bearing forging, the top and bottom of the material receiving frame are open, and a rotating shaft is set in the lower left corner of the material receiving frame. A buffer spring net is set on the right side of the rotating shaft, and the right end of the buffer spring net is close to the right side wall of the material receiving frame; an upward push cylinder is set on the left side of the support plate on the right side below the material receiving frame, and the top of the upward push cylinder is connected to the right end of the bottom of the buffer spring net; an opening is set at the bottom of the left side of the material receiving frame, and a material receiving track inclined to the lower left is set on the left side of the opening.

[0004] The above device can realize the unified storage of the bearing components after processing, but after the bearing components fall into the material frame, they are easy to collide with the existing bearing components in the frame and cause damage. Summary of the invention

[0005] The utility model aims at the above problems existing in the prior art and provides a bearing inner and outer ring fine grinding blanking structure. The technical problem to be solved by the utility model is that the prior bearing components are easily damaged after blanking after processing.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A bearing inner and outer ring fine grinding blanking structure comprises a workbench, on which is provided a strip-shaped blanking track which is inclined. The invention is characterized in that the workbench also has a horizontally arranged material storage track which is perpendicular to the blanking track, the material storage track is butted against the lower end of the blanking track, a soft buffer block which can reciprocate along the setting direction of the material storage track is provided in the material storage track, the soft buffer block can move to the lower port of the blanking track and is opposite to the lower port of the blanking track along the length direction of the blanking track.

[0008] The unloading track arranged on the workbench is used to provide an unloading guide channel for the inner and outer ring components of the bearing that have been processed, so that the inner and outer ring components of the bearing can be rolled downward and transported along the inclined unloading track to realize unloading; by setting a storage track that is perpendicular to the unloading track and arranged horizontally, the storage track is connected to the lower end of the unloading track, and a soft buffer block that can reciprocate along the setting direction of the storage track is set on the storage track, so that it is opposite to the lower end of the unloading track. In this way, the bearing component rolling down along the unloading track will first hit the soft buffer block and stop rolling. Since the soft buffer block is soft, it can avoid damage to the component by collision. After that, the soft buffer block moves backward in the horizontal direction to make the bearing component fall into the storage track at a low speed and remain upright. Before the subsequent bearing component falls, the soft buffer block can be pushed out again to be opposite to the lower end of the unloading track and provide buffering. At the same time, the previous bearing component that has fallen into the storage track can be pushed out and aligned. Rigid contact can be avoided during the pushing process to ensure that the processed bearing component is not damaged.

[0009] In the above-mentioned bearing inner and outer ring fine grinding blanking structure, the storage track includes at least two guide rods arranged in parallel and fixedly connected to the workbench, the two guide rods are arranged horizontally and are spaced along the setting direction of the blanking track, and the soft buffer block is arranged between the two guide rods. In this way, the bearing component can be supported between the guide rods to reduce contact friction and reduce friction resistance during the pushing process, and at the same time, it is conducive to reducing the interference generated when the operator takes out the aligned bearing components, which is convenient for operation and reduces the probability of wear of the bearing components. The storage track can also be an arc-shaped groove opened on the workbench.

[0010] In the above-mentioned bearing inner and outer ring fine grinding material discharge structure, both sides of the lower end of the material discharge track in the width direction are provided with vertically arranged limit plates, and the two limit plates are parallel and arranged at intervals along the setting direction of the material storage track. In this way, when the soft buffer block is withdrawn relative to the bearing component, the bearing component can be constrained between the limit plates on both sides to maintain an upright state, thereby preventing the bearing component from tipping over and causing scratches and damage during the subsequent pushing process.

[0011] In the above-mentioned bearing inner and outer ring fine grinding material blanking structure, one end of the material storage track is fixedly provided with a driving cylinder arranged along the setting direction of the material storage track, and the soft buffer block is fixedly connected to the output end of the driving cylinder. In this way, the reciprocating motion of the soft buffer block is controlled by the driving cylinder, which is conducive to the rapid response of the soft buffer block. The soft buffer block can also be driven by a motor screw mechanism, and the movement is stable and accurate.

[0012] In the above-mentioned bearing inner and outer ring fine grinding blanking structure, the soft buffer block is strip-shaped and arranged in the up-down direction, and the upper end of the soft buffer block is higher than the limit plate at the lower end of the blanking track. In this way, the soft buffer block has a larger coverage range, which is conducive to ensuring a more stable constraint effect on the bearing component, and at the same time, it is conducive to reducing the rolling stroke of the bearing component after the soft buffer block is withdrawn, reducing the collision force, and in addition, it can ensure that the upper and lower forces can be applied simultaneously when the bearing component is pushed out, ensuring the stable state of the bearing component when it is pushed out, and ensuring the alignment effect.

[0013] In the above bearing inner and outer ring fine grinding blanking structure, the soft buffer block is a rubber material piece or a plastic piece. The rubber material piece has good elasticity and is conducive to reducing collision damage, and the plastic piece has good wear resistance while achieving a buffering effect.

[0014] Compared with the prior art, the advantages of the utility model are as follows:

[0015] The bearing inner and outer ring fine grinding blanking structure can avoid bumping and damage to the processed bearing components during blanking by arranging soft buffers in the storage track, and is also conducive to the alignment of the bearing components after blanking. The soft buffers play a buffering role in multiple steps, further reducing the damage that may occur during the unified picking process. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0023] like Figure 1-2As shown, the bearing inner and outer ring finishing grinding blanking structure includes a workbench 1, which can be a working platform of existing processing equipment. The workbench 1 is provided with a blanking track 2 which is arranged in a strip shape and tilted, and the blanking track 2 is the blanking track 2 of the finishing equipment. The workbench 1 also has a storage track 3 which is arranged horizontally and perpendicular to the blanking track 2, and the storage track 3 is connected to the lower end of the blanking track 2. A soft buffer block 4 which can reciprocate along the setting direction of the storage track 3 is provided at one end of the storage track 3, and the soft buffer block 4 can move to the lower port of the blanking track 2 to block it and prevent the bearing components from entering the blanking track 2. The unloading track 2 arranged on the workbench 1 is used to provide a unloading guide channel for the inner and outer ring components of the bearing that have been processed, so that the inner and outer ring components of the bearing can be rolled downward and transported along the inclined unloading track 2 to realize unloading; by setting a storage track 3 that is perpendicular to the unloading track 2 and arranged horizontally, the storage track 3 is connected to the lower end of the unloading track 2, and a soft buffer block 4 that can reciprocate along the setting direction of the storage track 3 is set on the storage track 3, so that it is opposite to the lower end of the unloading track 2, so that the bearing component rolling down along the unloading track 2 will first hit the soft buffer block 4 and stop rolling. Since the soft buffer block 4 is soft, it can avoid damage to the component by collision. After that, the soft buffer block 4 moves backward in the horizontal direction to make the bearing component fall into the storage track 3 at a low speed and remain upright. Before the subsequent bearing component falls, the soft buffer block 4 can be pushed out again to be opposite to the lower end of the unloading track 2 and provide buffering. At the same time, the previous bearing component that falls into the storage track 3 can be pushed out and aligned. Rigid contact can be avoided during the pushing process to ensure that the processed bearing component is not damaged. Specifically, the storage track 3 includes three guide rods 31 arranged in parallel and fixedly connected to the workbench 1. The guide rods 31 are arranged horizontally and are spaced along the setting direction of the unloading track 2. The soft buffer block 4 is arranged between the two guide rods 31. In this way, the bearing component can be supported between the two guide rods 31, and the other guide rod 31 is supported on the bottom of the bearing component to reduce contact friction and reduce friction resistance during the pushing process. At the same time, it is helpful to reduce the interference caused by the operator when taking out the aligned bearing components. The operation is convenient and the probability of bearing component wear is reduced. Both sides of the lower end of the unloading track 2 in the width direction are provided with vertically arranged limit plates 21. The two limit plates 21 are parallel and spaced along the setting direction of the storage track 3. In this way, the soft buffer block 4 can constrain the bearing component to remain upright between the limit plates 21 on both sides during the retreat process relative to the bearing component, so as to prevent the bearing component from tipping over and causing scratches and damage during the subsequent pushing process. Preferably, the end of the storage track 3 where the soft buffer block 4 is arranged is fixedly provided with a driving cylinder 5 arranged along the setting direction of the storage track 3, and the soft buffer block 4 is fixedly connected to the output end of the driving cylinder 5. In this way, the reciprocating motion of the soft buffer block 4 is controlled by the driving cylinder 5, which is conducive to the rapid response of the soft buffer block 4. The soft buffer block 4 is in a strip shape and is arranged in the up and down direction. The upper end of the soft buffer block 4 is higher than the limit plate 21 at the lower end of the unloading track 2, and the lower end is in the same position as the lowest guide rod 31.In this way, the soft buffer block 4 has a larger coverage area, which is conducive to ensuring a more stable restraining effect on the bearing component, and at the same time, it is conducive to reducing the rolling stroke of the bearing component after the soft buffer block 4 is withdrawn, reducing the collision force, and in addition, it can ensure that the upper and lower forces can be applied simultaneously when the bearing component is pushed out, ensuring the stable state of the bearing component when it is pushed out, and ensuring the alignment effect. The soft buffer block 4 is a plastic part. The plastic part has good wear resistance while achieving the buffering effect.
