Description

Technical Field

[0001] The invention relates to the technical field of plastic-coated bearing processing, in particular to a machine for removing the resin end cover of the outer ring of a plastic-coated bearing. Background Art

[0002] Plastic coated bearings generally refer to bearings coated with a layer of plastic on the outside. The plastic material is generally nylon PA, polyoxymethylene POM, engineering plastic polypropylene, etc. The outer plastic has a certain hardness, impact resistance, friction resistance, and has a certain self-lubricating property.

[0003] Plastic coated bearings are a newly emerging industry in China. They are widely used in mechanical equipment, industrial assembly lines, furniture and hardware accessories. According to different application purposes, the appearance of plastic coated bearings can be made into different shapes; In the automotive industry, plastic-coated bearings are commonly used in sliding doors of cars. They usually include a plastic shell, an outer ring and an inner ring. The plastic shell is wrapped around the outer ring, and the inner ring is connected to the door. By abutting the plastic shell against the guide rail of the door, a sliding guide and support for the door is formed. When the plastic-coated bearing is processed, the outer ring of the plastic-coated bearing will be accompanied by a resin end cover. In order to ensure the normal use of the plastic-coated bearing, the resin end cover of the outer ring of the plastic-coated bearing needs to be removed. The existing method of removing the resin end cover of the outer ring of the plastic-coated bearing is mainly to use a traditional CNC lathe for pre-cutting processing, and then manually knock the cover to remove the cover. This method has the following defects: 1. Manual operation has high labor intensity, which is easy to cause fatigue, and there are safety hazards (hands may be hit or cut by the machine). At the same time, the product quality is unstable (the product is easily scratched); 2. The working procedures are scattered and unfocused, and the working efficiency is low, which may cause personal injury accidents (hand injuries) when knocking. Summary of the invention

A first electric hydraulic push rod 215 is provided on the side of the surface of the workbench 200 close to the Y-direction conveyor belt 211. A push block 216 for pushing the bearing is provided at the output end of the first electric hydraulic push rod 215. The push block 216 cooperates with the second notch. The specific operation is as follows: the centrifugal disc loader 600 loads the outer ring of the plastic-coated bearing onto the bearing conveying track through the first notch, and then drives the outer ring of the plastic-coated bearing to move to the second notch position through the Y-direction conveyor belt 211. When the outer ring of the plastic-coated bearing is transported to the second notch position, the first electric hydraulic push rod 215 works to push the push block 216 to move in the X direction, and then the push block 216 pushes the outer ring of the plastic-coated bearing from the second notch position to the X-direction feeding plate 700. A rear side plate 703 is provided on one side of the surface of the X-direction feeding plate 700, and the X-direction pushing mechanism 220 includes a second electric hydraulic push rod 221 fixedly mounted on the workbench 200 and a bottom plate 222 sliding along the X direction, the output end of the second electric hydraulic push rod 221 is fixedly connected to the bottom plate 222, a third electric hydraulic push rod 225 and a top plate 226 sliding along the Y direction are provided on the surface of the bottom plate 222, the output end of the third electric hydraulic push rod 225 is fixedly connected to the top plate 226, and one side of the top plate 226 is provided with a push rod 226 that is connected to the X-direction feeding plate The pusher plate 704 is parallel to 700, and the side of the pusher plate 704 is provided with bearing clamping grooves 705 at equal intervals. The bottom plate 222 can be pushed to slide along the X direction by the second electric hydraulic push rod 221, and the top plate 226 can be pushed to slide in the Y direction by the third electric hydraulic push rod 225, thereby driving the pusher plate 704 on the top plate 226 to move in the X direction and the Y direction, ensuring that the bearing clamping grooves 705 on the pusher plate 704 can push the outer ring of the plastic-coated bearing to move to the next station on the X-direction feeding plate; Specifically, the pushing process in the X direction is as follows: when the outer ring of the plastic-coated bearing is pushed onto the X-direction feeding plate 700 by the pushing block 216, the top plate 226 is first pushed to slide in the Y direction by the third electric hydraulic push rod 225, and the pushing transverse plate 704 on the top plate 226 is driven to move in the Y direction, thereby driving the bearing clamping groove 705 to clamp the outer ring of the plastic-coated bearing, and then the bottom plate 222 is pushed to slide along the X direction by the second electric hydraulic push rod 221, and the pushing transverse plate 704 is driven to move in the X direction, thereby pushing the outer ring of the plastic-coated bearing to move rightward on the X-direction feeding plate 700 through the bearing clamping groove 705, and the one-time moving distance of the outer ring of the plastic-coated bearing is, Just move the outer ring of the plastic-coated bearing to the next station. After the pusher cross plate 704 and the bearing clamping groove 705 push the outer ring of the plastic-coated bearing to move once, the third electric hydraulic push rod 225 drives the top plate 226 to slide outward in the Y direction, and at the same time drives the pusher cross plate 704 on the top plate 226 to move outward in the Y direction, thereby driving the bearing clamping groove 705 to separate from the outer ring of the plastic-coated bearing.

If the direction of the outer ring of the plastic-coated bearing is wrong, the direction is flipped by the bearing direction flipping mechanism 240, and then the periphery of the outer ring of the plastic-coated bearing is cut by the bearing cutting mechanism 800.

When one plastic-coated bearing outer ring is pushed to the position of the bearing direction identification mechanism 230, the previous plastic-coated bearing outer ring is pushed to the bearing direction flipping mechanism 240, and so on. The previous plastic-coated bearing outer ring is pushed to the bearing cutting mechanism 800, and the previous plastic-coated bearing outer ring is pushed to the position of the bearing direction flipping mechanism 240 and the position of the end cover stamping mechanism 250 in turn.

[0038] Working principle: the outer ring of the plastic-coated bearing is put into the storage bin 502 for storage, and then the storage mechanism 500 feeds the centrifugal disc loader 600, and then the centrifugal disc loader 600 sequentially unloads the outer ring of the plastic-coated bearing to the Y-direction feeding mechanism 210. During the feeding process of the centrifugal disc loader 600, the inductive sensor 507 detects the state of the inductive feeding in real time. When the number of products in the centrifugal disc loader 600 is less than the set number, the information is fed back to the storage bin 502, and then the storage bin 502 is fed again. Feeding, ensuring that the centrifugal disc loader 600 can continuously feed the next process uninterruptedly; then the centrifugal disc loader 600 loads the outer ring of the plastic-coated bearing onto the bearing conveying track through the first notch, and then drives the outer ring of the plastic-coated bearing to move to the second notch position through the Y-direction conveyor belt 211. When the outer ring of the plastic-coated bearing is transported to the second notch position, the first electric hydraulic push rod 215 works, and the first electric hydraulic push rod 215 pushes the push block 216 to move in the X direction, and then the push block 216 pushes the outer ring of the plastic-coated bearing from the first notch to the second notch position.

If the direction of the outer ring of the plastic-coated bearing is wrong, the direction is flipped by the bearing direction flipping mechanism 240, and then the periphery of the outer ring of the plastic-coated bearing is cut by the bearing cutting mechanism 800, and then the direction of the passing outer ring of the plastic-coated bearing is flipped by the next bearing direction flipping mechanism 240, so that the blocking port of the outer ring of the plastic-coated bearing is located at the bottom, and then the end cover stamping mechanism 250 is used to stamp the outer ring of the plastic-coated bearing.
