Description

Technical Field

[0001] The utility model belongs to the technical field of bearing processing equipment and relates to a pre-grinding feeding device for bearing components. Background Art

[0002] The bearing components include the outer ring and the inner ring. During the processing and assembly of the bearing components, they need to be loaded in an orderly manner. The ordinary loading method has a small loading quantity and a complex loading device. It is not suitable for mass production of products, is labor-intensive and time-consuming, has very low efficiency, and has very high production costs.

[0003] The patent application with the publication number CN106144537A discloses an automatic bearing feeding device, including a support platform, a material guiding device arranged on the support platform, a guide device arranged on the support platform at one side of the material guiding device, a material blocking device arranged between the material guiding device and the guide device, and a bearing crimping seat connected to the lower end of the guide device. The material guiding device is composed of a material stacking rack with an angle relative to a horizontal plane, an L-shaped material pushing baffle plate arranged at the bottom of the material stacking rack, a lifting cylinder arranged at the bottom of the material pushing baffle plate, a material pushing cylinder arranged at one end of the material pushing baffle plate, and a material pushing block fixedly connected to the free end of the piston rod of the material pushing cylinder and located above the material pushing baffle plate.

[0004] The above device can realize automatic loading of bearings, but there are still some shortcomings: when the bearing component on the stacking rack rolls onto the push baffle, the bearing component will collide and rebound with the push baffle, and collide with the bearing component behind it many times, which is easy to cause collision damage. Summary of the invention

[0005] The utility model aims at the above problems existing in the prior art and provides a bearing component pre-grinding feeding device. The technical problem to be solved by the utility model is that the existing feeding device easily causes collisions during the bearing feeding process.

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

[0007] A pre-grinding loading device for bearing components comprises a placing table, on which is provided an inclined material coding plate, at the lower edge of which is provided a material pushing track, and is characterized in that a cylinder is fixedly provided on the placing table, and the cylinder is horizontally arranged and perpendicular to the material pushing track, and the movable end of the cylinder is connected to a material receiving plate which is in a strip shape and arranged in parallel with the material pushing track, and the material receiving plate is located above the material pushing track and opposite to the lower edge of the material coding plate along the setting direction of the cylinder.

[0008] The bearing components on the material stacking plate can roll toward the pushing track by themselves under the action of gravity. The pushing track is used to place rows of bearing components so as to facilitate the unloading of materials one by one. The movable end of cylinder 1 is connected to the receiving plate arranged in parallel with the pushing track, and the receiving plate and the material stacking plate are arranged on both sides of the width direction of the pushing track respectively. In this way, before the next batch of bearing components rolls onto the pushing track, cylinder 1 can push the receiving plate to extend to the vicinity of the lower edge of the material stacking plate. The distance between the rows of bearing components on the coding plate and the receiving plate is very small, thereby reducing impact and collision. Subsequently, cylinder 1 contracts to drive the receiving plate to gradually reset to one side of the pushing track, so that the bearing components fall smoothly onto the pushing track, and no repeated collision and collision will occur due to rapid impact, thereby reducing the probability of bearing components being damaged by collision.

[0009] In the above-mentioned bearing component pre-grinding feeding device, the placement table has a plurality of guide sleeves parallel to the cylinder 1, and the side of the receiving plate away from the coding plate has a plurality of guide rods parallel to the cylinder 1, and the guide rods are evenly distributed on both sides of the cylinder 1, and the guide rods are respectively slidably inserted in the guide sleeves. In this way, the receiving plate can be guided away from the position connected to the cylinder 1, so that the overall movement state of the receiving plate remains stable, and then the row of bearing components remain concentric during the movement process, avoiding the dislocation of individual bearing components, causing bumps or even falling.

[0010] In the above-mentioned bearing component pre-grinding feeding device, the placement table is provided with a screw drive mechanism, and the movable end of the screw drive mechanism is connected to a pusher that can reciprocate horizontally along the pusher track. The screw drive mechanism can make the pusher move more smoothly and accurately, and reduce the probability of collision and damage during the pushing process of the bearing component.

[0011] In the above-mentioned bearing component pre-grinding feeding device, a gate knife that can reciprocate up and down is provided on the placement table. The gate knife is vertically arranged and parallel to the pushing track. The gate knife is vertically opposite to the lower edge of the material stacking plate, and the lower side of the gate knife is chamfered. The gate knife can separate the rows of bearing components from the bearing components stored on the material stacking plate after they enter the pushing track, avoiding interference with the bearing components to be pushed out, and the lower side of the gate knife can more smoothly separate the abutting bearing components.

[0012] In the above-mentioned bearing component pre-grinding feeding device, a horizontally arranged cylinder 2 is connected to the edge of the placing table and is perpendicular to the receiving plate. A push rod is connected to the movable end of the cylinder 2. The push rod is arranged in parallel with the cylinder 2. The discharge end of the pushing track has a downwardly inclined unloading track. The unloading track is perpendicular to the pushing track. The push rod is located at the junction of the unloading track and the pushing track. In this way, the bearing component pushed to the discharge end of the pushing track can still maintain a stable position, and the push rod driven by the cylinder 2 pushes it horizontally into the unloading track, so that the bearing component can roll and unload to avoid jamming and collision.

[0013] In the above-mentioned bearing component pre-grinding feeding device, the outer end of the push rod has an arc-shaped notch that can match the outer contour of the bearing component. This can increase the contact area between the push rod and the bearing component, reduce the local force on the bearing component, and weaken the impact of collision.

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

[0015] The bearing component pre-grinding feeding device can receive the rolling bearing component onto the pushing track by arranging a receiving plate, thereby eliminating the impact rebound when the bearing component is unloaded, thereby avoiding damage due to knocking and ensuring the bearing processing quality.

[0027] 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.

[0028] like Figure 1-4As shown, the pre-grinding loading device for bearing components includes a placing table 1, on which is provided an inclined material coding plate 11, at the lower edge of which is provided a material pushing track 12, and on the placing table 1 is fixed a cylinder 2, which is horizontally arranged and perpendicular to the material pushing track 12, and the movable end of the cylinder 2 is connected to a material receiving plate 3 arranged in parallel with the material pushing track 12, the material receiving plate 3 is opposite to the lower edge of the material coding plate 11 along the width direction of the material pushing track 12, and the material receiving plate 3 and the material coding plate 11 are respectively located on both sides of the width direction of the material pushing track 12. Then, the cylinder 12 contracts and drives the receiving plate 3 to gradually return to the side of the pushing track 12, so that the bearing components fall smoothly onto the pushing track 12, and no repeated collisions and knocks will occur due to rapid impact, thereby reducing the probability of damage to the bearing components. Preferably, the placing table 1 has two guide sleeves 13 parallel to the cylinder 1-2, and the side of the receiving plate 3 away from the coding plate 11 has two guide rods 31 parallel to the cylinder 1-2, and the two guide rods 31 are evenly distributed on both sides of the cylinder 1-2, and the guide rods 31 are respectively slidably inserted in the guide sleeves 13. In this way, the receiving plate 3 can be guided away from the position connected to the cylinder 1-2, so that the overall movement state of the receiving plate 3 remains stable, and then the row of bearing components remain concentric during the movement process, avoiding the dislocation of individual bearing components to cause bumps or even fall.

[0029] like Figure 1-4 As shown, a screw drive mechanism 4 is provided on the placement table 1, and a pusher 5 that can reciprocate horizontally along the push track 12 is connected to the movable end of the screw drive mechanism 4. The screw drive mechanism 4 is an existing mechanism, and the pusher 5 is fixedly connected to the movable nut of the screw drive mechanism 4. The screw drive mechanism 4 can make the pusher 5 move more smoothly and accurately, and reduce the probability of damage caused by collision during the pushing process of the bearing component. A gate knife 6 that can reciprocate up and down is also provided on the placement table 1. The gate knife 6 is vertically arranged and parallel to the push track 12. The gate knife 6 is vertically opposite to the lower edge of the code plate 11, and the lower side of the gate knife 6 is chamfered. The gate knife 6 can separate the bearing components stored on the code plate 11 after the rows of bearing components enter the push track 12, so as to avoid interference with the bearing components to be pushed out, and the lower side of the gate knife 6 can more smoothly separate the abutting bearing components.

[0030] like Figure 1 , Figure 2 and Figure 5 As shown, the edge of the placing table 1 is connected with a cylinder 2 7 which is horizontally arranged and perpendicular to the receiving plate 3, and a push rod 8 is connected to the movable end of the cylinder 2 7, and the push rod 8 is arranged in parallel with the cylinder 2 7. The discharge end of the pushing track 12 has a feed track 9 which is inclined downward, and the feed track 9 is perpendicular to the pushing track 12, and the push rod 8 is located at the junction of the feed track 9 and the pushing track 12. In this way, the bearing component pushed to the discharge end of the pushing track 12 can still maintain a stable position, and the push rod 8 driven by the cylinder 2 7 pushes it horizontally into the feed track 9, so that the bearing component can roll and discharge, avoiding jamming and collision. Specifically, the outer end of the push rod 8 has an arc-shaped notch 81 that can match the outer contour of the bearing component. In this way, the contact area between the push rod 8 and the bearing component can be increased, the local force of the bearing component can be reduced, and the impact of collision can be weakened.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
