Description

Technical Field

[0001] The present invention relates to the technical field of plastic-coated bearing processing, and specifically relates to a resin end cap removing machine for the outer ring of a plastic-coated bearing. Background Technique

[0002] A plastic-coated bearing generally refers to a bearing with a layer of plastic wrapped 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 performance.

[0003] Plastic-coated bearings are a newly emerging industry in China in recent years. They have a wide range of applications and are widely used in mechanical equipment, industrial assembly lines, furniture, and hardware fittings. According to different application purposes, the outer shape of plastic-coated bearings can be made into different shapes;

[0004] In the automotive industry, plastic-coated bearings are commonly used at the sliding doors of automobiles. They usually include a plastic housing, an outer ring, and an inner ring. The plastic housing is wrapped around the outer ring, and the inner ring is connected to the car door. By abutting the plastic housing against the guide rail of the car door, sliding guidance and support for the car door are formed;

[0005] When processing plastic-coated bearings, the outer ring of the plastic-coated bearing will be connected with a resin end cap. In order to ensure the normal use of the plastic-coated bearing, it is necessary to remove the resin end cap connected to the outer ring of the plastic-coated bearing. The existing method for removing the resin end cap of the outer ring of the plastic-coated bearing is mainly to use a traditional CNC lathe for pre-cutting processing, and then the operation of removing the cap is carried out by manual hammering. This method has the following defects:

[0006] 1. Manual operation has a high labor intensity for workers, is prone to fatigue operation, and has potential safety hazards (hands are bruised or cut by machinery). At the same time, the product quality is unstable (the product is easily scratched);

[0007] 2. The processes are scattered and not centralized, and the work efficiency is low. Personal injury accidents (injuring hands) may occur during the knocking process. Summary of the Invention

When the plastic-coated bearing outer rings are transferred onto the X-direction feeding plate, a second electro-hydraulic push rod is used to push the bottom plate to slide along the X direction, and a third electro-hydraulic push rod is used to push the top plate to slide in the Y direction, so as to drive the pushing cross plate on the top plate to move in the X direction and the Y direction, ensuring that the bearing clamping groove on the pushing cross plate can push the plastic-coated bearing outer rings to move to the next station on the X-direction feeding plate. Then, the plastic-coated bearing outer rings sequentially pass through a bearing direction identification mechanism, a bearing direction flipping mechanism, a bearing cutting mechanism, a bearing direction flipping mechanism, and an end cap stamping mechanism on the X-direction feeding plate. The bearing direction identification mechanism identifies the direction of the plastic-coated bearing outer rings. If the direction of the plastic-coated bearing outer rings is incorrect, the bearing direction flipping mechanism is used to flip the direction. Then, the periphery of the plastic-coated bearing outer rings is cut by the bearing cutting mechanism. Next, the plastic-coated bearing outer rings passing through are flipped in direction by the bearing direction flipping mechanism, so that the sealing port of the plastic-coated bearing outer rings is located below. Then, the end cap stamping mechanism is used to perform end cap stamping on the plastic-coated bearing outer rings. During the entire automated production process, the action cycle is unified. Through batch production by automated equipment, unmanned operation is realized, the product quality is stable, and the production efficiency is greatly improved; remarkable effects of reducing labor, improving efficiency, improving quality stability, and operation safety are achieved.

Specific embodiments

[0056] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0057] Please refer to Figures 1-5 , the present invention provides a machine for removing the resin end cap of the plastic-coated bearing outer ring, which includes a support frame 100. A workbench 200 is provided on the top of the support frame 100. A top frame 300 is provided on the workbench 200. A storage mechanism 500 is provided on one side of the support frame 100. A centrifugal disk loader 600 is provided on the surface of the workbench 200 corresponding to the discharge port of the storage mechanism 500. The storage mechanism 500 includes a support plate 501 fixedly installed on one side of the support frame 100. Columns 504 are provided on the lower surface of the support plate 501. A storage bin 502 is provided on the support plate 501. A discharge chute 503 extending above the centrifugal disk loader 600 is provided at the discharge port of the storage bin 502. The plastic-coated bearing outer rings are put into the storage bin 502 for storage, which can meet the requirements of subsequent processing and eliminates the need for operators to frequently supply materials.

[0058] Wherein, a vertical rod 505 is provided on one side of the surface of the support plate 501. A cross rod 506 is provided at the top of the vertical rod 505. An inductive sensor 507 extending into the centrifugal disk loader 600 is provided at the free end of the cross rod 506. The inductive sensor 507 is used to detect the loading speed of the centrifugal disk loader 600. The storage mechanism 500 supplies materials to the centrifugal disk loader 600, and then the centrifugal disk loader 600 sequentially unloads the plastic-coated bearing outer rings onto the Y-direction feeding mechanism 210. During the loading process of the centrifugal disk loader 600, the inductive sensor 507 is used to detect the feeding state in real time. When the number of products in the centrifugal disk loader 600 detected is less than the set number, the information is fed back to the storage bin 502, and then the storage bin 502 supplies materials again to ensure that the centrifugal disk loader 600 can continuously supply materials to the next process without interruption;

[0059] A Y-direction feeding mechanism 210 is provided at the position on the surface of the workbench 200 corresponding to the centrifugal disk loader 600. An X-direction feeding plate 700 is provided at the position on the surface of the workbench 200 corresponding to the end of the Y-direction feeding mechanism 210. The Y-direction feeding mechanism 210 includes a Y-direction conveyor belt 211 arranged on the workbench 200. A second driving motor 212 for driving the transmission of the Y-direction conveyor belt 211 is provided on one side of the surface of the workbench 200. A first protective plate 213 is provided above one side of the Y-direction conveyor belt 211, and a second protective plate 214 is provided above the other side of the Y-direction conveyor belt 211. A bearing transmission track is formed between the first protective plate 213 and the second protective plate 214. A first notch communicating with the bearing transmission track is provided on the side of the first protective plate 213 close to the discharge port of the centrifugal disk loader 600. A second notch communicating with the bearing transmission track is provided on the side of the second protective plate 214 close to the X-direction feeding plate 700. A first electro-hydraulic push rod 215 is provided on the surface of the workbench 200 close to the Y-direction conveyor belt 211. A pushing block 216 for pushing the bearing is provided at the output end of the first electro-hydraulic push rod 215. The pushing block 216 cooperates with the second notch;

[0060] The specific operation is as follows: The centrifugal disk loader 600 feeds the plastic-coated bearing outer ring onto the bearing transmission track through the first notch, and then drives the plastic-coated bearing outer ring to move towards the second notch position through the Y-direction conveyor belt 211. When the plastic-coated bearing outer ring is conveyed to the second notch position, the first electro-hydraulic push rod 215 works, and the first electro-hydraulic push rod 215 pushes the pushing block 216 to move in the X direction, and then the pushing block 216 pushes the plastic-coated bearing outer ring from the position of the second notch onto the X-direction feeding plate 700;

[0061] A rear side plate 703 is provided on one side of the surface of the X-direction feeding plate 700. The X-direction pushing mechanism 220 includes a second electro-hydraulic push rod 221 fixedly installed on the workbench 200 and a bottom plate 222 sliding in the X direction. The output end of the second electro-hydraulic push rod 221 is fixedly connected to the bottom plate 222. A third electro-hydraulic push rod 225 and a top plate 226 sliding in the Y direction are provided on the surface of the bottom plate 222. The output end of the third electro-hydraulic push rod 225 is fixedly connected to the top plate 226. A pushing cross plate 704 parallel to the X-direction feeding plate 700 is provided on one side of the top plate 226. Bearing clamping grooves 705 are provided at equal intervals on the side surface of the pushing cross plate 704. By the second electro-hydraulic push rod 221, the bottom plate 222 can be pushed to slide in the X direction. By the third electro-hydraulic push rod 225, the top plate 226 can be pushed to slide in the Y direction, so as to drive the pushing cross 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 pushing cross plate 704 can push the plastic-coated bearing outer ring to move to the next station on the X-direction feeding plate;

[0062] 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, first, the third electro-hydraulic push rod 225 is used to push the top plate 226 to slide in the Y direction, and at the same time, drive the pushing cross plate 704 on the top plate 226 to move in the Y direction, so as to drive the bearing clamping groove 705 to clamp the outer ring of the plastic-coated bearing. Then, the second electro-hydraulic push rod 221 is used to push the bottom plate 222 to slide along the X direction, and at the same time, drive the pushing cross plate 704 to move in the X direction, so as to push 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 primary moving distance of the outer ring of the plastic-coated bearing just makes the outer ring of the plastic-coated bearing move to the next working station. After the pushing cross plate 704 and the bearing clamping groove 705 push the outer ring of the plastic-coated bearing to move once, the third electro-hydraulic push rod 225 is used to drive the top plate 226 to slide outward in the Y direction, and at the same time, drive the pushing cross plate 704 on the top plate 226 to move outward in the Y direction, so as to drive the bearing clamping groove 705 to disengage from the outer ring of the plastic-coated bearing. Then, the second electro-hydraulic push rod 221 is used to drive the bottom plate 222 to slide leftward along the X direction, and at the same time, drive the pushing cross plate 704 to move leftward in the X direction, so that the X-direction pushing mechanism 220 returns to its original state, preparing for the next pushing of the outer ring of the plastic-coated bearing.

[0063] On one side of the surface of the workbench 200 close to the X-direction feeding plate 700, there are successively arranged a bearing direction recognition mechanism 230, a bearing direction flipping mechanism 240, a bearing cutting mechanism 800, a bearing direction flipping mechanism 240, and an end cap stamping mechanism 250. On the other side of the surface of the workbench 200 close to the X-direction feeding plate 700, there is an X-direction pushing mechanism 220; the outer ring of the plastic-coated bearing passes successively through the bearing direction recognition mechanism 230, the bearing direction flipping mechanism 240, the bearing cutting mechanism 800, the bearing direction flipping mechanism 240, and the end cap stamping mechanism 250 on the X-direction feeding plate 700. The bearing direction recognition mechanism 230 is used to recognize the direction of the outer ring of the plastic-coated bearing. If the direction of the outer ring of the plastic-coated bearing is incorrect, the bearing direction flipping mechanism 240 is used to flip the direction. Then, the outer periphery of the outer ring of the plastic-coated bearing is cut by the bearing cutting mechanism 800. Then, the bearing direction flipping mechanism 240 flips the passing outer ring of the plastic-coated bearing so that the sealing port of the outer ring of the plastic-coated bearing is located below. Then, the end cap of the outer ring of the plastic-coated bearing is stamped by the end cap stamping mechanism 250. During the entire automated production process, the action cycle is unified, and through the batch production of automated equipment, unmanned operation is realized.

[0064] Further, the material pushing cross plate 704 and the bearing clamping groove 705 push the plastic-coated bearing outer ring to move a distance corresponding to each station. When a 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 even more previous plastic-coated bearing outer ring is pushed to the bearing cutting mechanism 800, and the previous plastic-coated bearing outer rings are successively pushed to the position of the bearing direction flipping mechanism 240 and the end cover stamping mechanism 250.

[0065] Among them, the bearing direction identification mechanism 230 includes a first vertical plate 231 fixedly installed on the surface of the workbench 200. A vertical first electric slide rail 232 is provided on the first vertical plate 231. A first electric slider is slidably installed on the first electric slide rail 232. A first linear resistive sensor 233 is provided on the first electric slider. The first linear resistive sensor 233 is used to identify the direction of the bearing. Since the entire process has requirements for the product direction unity, the first linear resistive sensor 233 is used for measurement, and the direction of the product is identified through analog conversion. If the direction is incorrect, the subsequent process uses the bearing direction flipping mechanism 240 to flip the direction.

[0066] Among them, the bearing direction flipping mechanism 240 includes a second vertical plate 241 fixedly installed on the surface of the workbench 200. A flipping motor 242 is provided on the second vertical plate 241. A flipping rod 243 is provided at the output end of the flipping motor 242. A bearing clamping groove 244 is formed through the flipping rod 243; a flipping groove 702 is formed on the surface of the X-direction feeding plate 700 corresponding to the position of the bearing direction flipping mechanism 240. The flipping rod 243 extends into the flipping groove 702. When the bearing clamping groove 244 is in a horizontal state, the lower side surface of the bearing clamping groove 244 is on the same horizontal plane as the surface of the X-direction feeding plate 700. When the plastic-coated bearing outer ring is pushed to the position of the bearing direction flipping mechanism 240, the plastic-coated bearing outer ring is pushed into the bearing clamping groove 244.

The active roller 115 is connected to the driven roller 113 through a belt 116. When the outer ring of the plastic-coated bearing needs to be cut, the outer ring of the plastic-coated bearing to be cut is first clamped on the pneumatic expansion chuck 118, and then the active roller 115 is driven to rotate by the first driving motor 114. Then, the rotating shaft 112 is driven to rotate through the transmission relationship between the active roller 115 and the driven roller 113, thereby driving the outer ring of the plastic-coated bearing on the pneumatic expansion chuck 118 to rotate, thereby adjusting the orientation of the outer ring of the plastic-coated bearing, so that the cutting knife 825 can cut different positions of the outer ring of the plastic-coated bearing.

[0071] The clamping structure 830 includes a fifth vertical plate 831 arranged on the surface of the workbench 200, and the fifth vertical plate 831 is provided with a third electric slide rail 832 arranged in the Y direction, and the third electric slide rail 832 is slidably installed on the third electric slide rail 833, and the third electric slide rail 833 is provided with a fourth electric slide rail 834 arranged in the Z direction, and the fourth electric slide rail 834 is slidably installed on the fourth electric slide rail, and the fourth electric slide rail 834 is provided with a fourth electric slide.

It is ensured that the pneumatic clamping jaw 836 can move in the Y direction and the Z direction, which is convenient for adjusting the position of the pneumatic clamping jaw 836 in these two directions.

[0072] Furthermore, in order to ensure the stability and consistency of the clamping of the outer ring of the plastic-coated bearing, three sets of second linear resistive sensors are provided in the pneumatic clamp 836 to measure the parallelism of the end faces of the outer ring of the plastic-coated bearing. If the clamping tilt exceeds the designed parallelism value, resulting in failure of smooth cutting, the equipment will issue an alarm.

[0073] The specific working principle of the bearing cutting mechanism 800 is as follows: When the plastic-coated bearing outer ring is pushed to the position of the bearing cutting mechanism 800, first, the fourth electric slide rail 834 and the fourth electric slider cooperate to drive the pneumatic gripper 836 to move downward in the Z direction. Then, the pneumatic gripper 836 clamps the plastic-coated bearing outer ring. Next, the fourth electric slide rail 834 and the fourth electric slider cooperate to drive the pneumatic gripper 836 to move upward in the Z direction. Then, the third electric slide rail 832 and the third electric slider 833 cooperate to drive the pneumatic gripper 836 and the plastic-coated bearing outer ring to move inward in the Y direction, so as to move the plastic-coated bearing outer ring directly above the pneumatic expansion chuck 118 inside the cutting cover 841. Then, the fourth electric slide rail 834 and the fourth electric slider cooperate to drive the pneumatic gripper 836 to move downward in the Z direction, and the plastic-coated bearing outer ring on the pneumatic gripper 836 is clamped onto the pneumatic expansion chuck 118. Then, the pneumatic gripper 836 is moved to the original position. Next, the servo motor 811 drives the lead screw 812 to rotate. During the rotation of the lead screw 812, the connecting plate 814 moves along the Y direction through the cooperation of the nut sleeve and the lead screw 812, so as to drive the cutting structure 820 on the mounting plate to move in the Y direction, making the cutting structure 820 approach the plastic-coated bearing outer ring. Then, through the cooperation of the second electric slide rail 822 and the second electric slider 823, the position of the cutting tool 825 in the Z direction is adjusted. The outer periphery of the plastic-coated bearing outer ring on the pneumatic expansion chuck 118 is cut by the cutting tool 825. At the same time, during the cutting process, the driving mechanism 110 drives the pneumatic expansion chuck 118 to rotate, facilitating the all-round cutting of the outer ring of the plastic-coated bearing outer ring.

[0075] The end cap stamping mechanism 250 includes a third vertical plate 251 fixedly installed on the surface of the workbench 200. A hydraulic cylinder 252 is provided at the top of the third vertical plate 251. A stamping slide base 253 is slidably installed on the front surface of the third vertical plate 251. The output end of the hydraulic cylinder 252 is fixedly connected to the stamping slide base 253. A stamping rod 254 is provided at the bottom of the stamping slide base 253, and a stamping head 255 is provided at the end of the stamping rod 254. After the plastic-coated bearing outer ring is processed by the bearing cutting mechanism 800, the clamping jaw structure 830 grabs the cut plastic-coated bearing outer ring onto the X-direction feeding plate 700, and then the X-direction pushing mechanism 220 continues to push the plastic-coated bearing outer ring forward, pushing the plastic-coated bearing outer ring onto the next bearing direction flipping mechanism 240. Then, the bearing direction flipping mechanism 240 flips the passing plastic-coated bearing outer ring so that the sealed port of the plastic-coated bearing outer ring is located below. Then, the X-direction pushing mechanism 220 continues to push the plastic-coated bearing outer ring forward, pushing the plastic-coated bearing outer ring to the end cap stamping mechanism 250. Then, the hydraulic cylinder 252 is used to push the stamping slide base 253 to slide downward in the vertical direction, driving the stamping rod 254 and the stamping head 255 to move downward at the same time. Then, the stamping head 255 performs end cap stamping on the plastic-coated bearing outer ring to stamp off the end cap of the plastic-coated bearing outer ring.

[0076] Among them, a stamping hole is penetrated through the surface of the X-direction feeding plate 700 corresponding to the position of the stamping head 255. A waste discharge pipe 202 is provided on the lower surface of the workbench 200 around the stamping hole. A waste box is provided on the support frame 100 corresponding to the end of the waste discharge pipe 202. The stamped end cap falls into the waste discharge pipe 202 through the stamping hole, and the stamped end cap is conveyed into the waste box through the waste discharge pipe 202 for collection.

[0077] Among them, a positioning groove 706 arranged in the Y direction is opened on the surface of the X-direction feeding plate 700 corresponding to the stamping hole. A bearing positioning mechanism 260 is provided on one side of the workbench 200 corresponding to the positioning groove 706. The bearing positioning mechanism 260 includes a fourth electro-hydraulic push rod 261 fixedly installed on the surface of the workbench 200. A positioning clamping rod 262 extending into the positioning groove 706 is provided at the output end of the fourth electro-hydraulic push rod 261. When the plastic-coated bearing outer ring is pushed to the end cap stamping mechanism 250, the positioning clamping rod 262 is pushed to move along the positioning groove 706 by the fourth electro-hydraulic push rod 261, and then the plastic-coated bearing outer ring is clamped and positioned on the X-direction feeding plate 700 by the positioning clamping rod 262, so that the plastic-coated bearing outer ring is directly below the stamping head 255, avoiding the position movement of the plastic-coated bearing outer ring during the stamping process.

[0078] Among them, an unloading chute 701 is provided at the end of the X-direction feeding plate 700, and a material box 120 is provided at the end of the support frame 100 corresponding to the position of the unloading chute 701. The material box 120 is located directly below the unloading chute 701. After the outer ring of the plastic-coated bearing is stamped, the X-direction pushing mechanism 220 continues to push the outer ring of the plastic-coated bearing forward, so that the stamped outer ring of the plastic-coated bearing falls into the material box 120 from the unloading chute 701.

[0079] Among them, it further includes a movable vacuum cleaner 400. A gas guide pipe 201 is provided between the input end of the vacuum cleaner 400 and the dust removal pipe 843. The input end of the vacuum cleaner 400 is connected to the cutting cover 841 through the gas guide pipe 201. When the cutting tool 825 cuts the outer ring of the outer ring of the plastic-coated bearing, the air in the cutting cover 841 is sucked out by the vacuum cleaner 400, so as to form a negative pressure cavity in the cutting cover 841, and the chips generated during the cutting process are extracted, ensuring the cleanliness in the cutting cover 841.

[0080] 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 supplies materials to the centrifugal disk feeder 600. Then, the centrifugal disk feeder 600 sequentially discharges the outer rings of the plastic-coated bearings onto the Y-direction feeding mechanism 210. During the feeding process of the centrifugal disk feeder 600, the inductive sensor 507 is used to detect the state of inductive feeding in real time. When the number of products in the centrifugal disk feeder 600 detected is less than the set number, the information is fed back to the storage bin 502, and then the storage bin 502 supplies materials again to ensure that the centrifugal disk feeder 600 can continuously supply materials to the next process without interruption. Then, the centrifugal disk feeder 600 feeds the outer rings of the plastic-coated bearings onto the bearing transfer track through the first notch, and then the Y-direction conveyor belt 211 drives the outer rings of the plastic-coated bearings to move towards the second notch position. When the outer ring of the plastic-coated bearing is transported to the second notch position, the first electro-hydraulic push rod 215 works, and the first electro-hydraulic push rod 215 pushes the push block 216 to move in the X direction. Then, the push block 216 pushes the outer ring of the plastic-coated bearing from the second notch position onto the X-direction feeding plate 700. Then, the outer rings of the plastic-coated bearings sequentially pass through the bearing direction identification mechanism 230, the bearing direction flipping mechanism 240, the bearing cutting mechanism 800, the bearing direction flipping mechanism 240, and the end cap stamping mechanism 250 on the X-direction feeding plate 700. The bearing direction identification mechanism 230 identifies the direction of the outer ring of the plastic-coated bearing. If the direction of the outer ring of the plastic-coated bearing is incorrect, the bearing direction flipping mechanism 240 flips the direction. Then, the bearing cutting mechanism 800 performs cutting treatment on the periphery of the outer ring of the plastic-coated bearing. Then, the next bearing direction flipping mechanism 240 flips the outer ring of the plastic-coated bearing passing through, so that the sealing port of the outer ring of the plastic-coated bearing is located below. Then, the end cap stamping mechanism 250 performs end cap stamping treatment on the outer ring of the plastic-coated bearing. During the entire automated production process, the action cycle is unified. Through batch production by automated equipment, unmanned operation is achieved, the product quality is stable, and the production efficiency is greatly improved; outstanding effects of reducing labor, improving efficiency, improving quality stability, and operation safety are achieved.
