Raw material cutting equipment for bearing race machining

Abstract

The invention discloses raw material cutting equipment for bearing race machining, and relates to the technical field of cutting equipment. Due to the fact that when a pipe is rotated, relative sliding occurs between rotation of the pipe and a component driving the pipe to rotate, the pipe is stopped, cutting time of different positions is different during cutting, and cutting quality is affected, through cooperation of a rubber strip and a rubber ring, when the rubber strip makes contact with the pipe, the rubber ring and the rubber strip are pressed to deform through contact pressure, and the rubber strip is cut. When the rubber ring drives the outer sleeve ring to be matched with the outer sleeve ring to drive the pipe to rotate, the contact pressure between the rubber ring and the surface of the pipe is increased, the contact area is increased, and the friction force between the rubber ring and the pipe during rotation is increased through the matching of the rotation after deformation deviation and the deformation of the rubber ring; and synchronous rotation of the pipe is guaranteed, and the situation that when the pipe is driven to rotate, rotation of the pipe and rotation of the rotating disc are not synchronous, the pipe is stopped, and the cutting time of different positions is different during cutting is avoided.

Description

Technical Field

[0002] The bearing race is an important part of the bearing. It usually refers to the annular part installed in the bearing seat, directly contacting the rolling element (such as a ball or roller) and providing a rolling track. It is also called a bearing ring. When producing the bearing race, cutting equipment is usually used to cut the tubular material into rings of corresponding sizes. The most common cutting method is laser cutting, which uses the high energy density of the focused laser beam to melt or gasify the raw material in an instant, thereby achieving the purpose of truncation. In the process of cutting the tube by laser beam, when the tube is rotated, relative sliding occurs between the tube and the components driving the tube to rotate, causing the tube to stagnate, resulting in different cutting times at different positions during cutting, affecting the cutting quality.

Through the cooperation of the rotating wheel and the side ring, when the pipe material is pulled, the sliding friction force is converted into rotational friction force through the rotation of the rotating wheel, and the resistance when pulling the pipe material is reduced, so that the pipe material can move smoothly. At the same time, the contact area is reduced through the contact between the side ring and the surface of the pipe material, thereby reducing the resistance when rotating the pipe material, so that the rotating tube mechanism can smoothly drive the pipe material to rotate, and avoid the rotation of the pipe material and the rotation of the rotating tube mechanism being out of sync, resulting in reduced cutting effect.

[0007] The present invention provides a raw material cutting device for bearing race processing, which has the following beneficial effects: 1. The raw material cutting equipment for the bearing race processing, through the cooperation of the rubber strip and the rubber ring, when contacting the pipe material, compresses the rubber ring and the rubber strip to deform through the contact pressure, so that the axial center position of the outer ring and the inner ring is offset, so that when the rubber ring drives the pipe material to rotate in cooperation with the outer cover ring, the rotation after the deformation deviation cooperates with the deformation of the rubber ring, thereby increasing the contact pressure between the pipe material surface and the contact area, increasing the friction between the pipe material and the pipe material during rotation, ensuring the synchronous rotation of the pipe material, avoiding the asynchronous rotation of the turntable when driving the pipe material to rotate, causing the pipe material to stagnate, resulting in different cutting times at different positions during cutting, affecting the cutting quality.

[0008] 2. The raw material cutting equipment for processing the bearing race can make the axis center position of the pipe material and the axis center position of the slide ring as close as possible through the elastic force generated by the elastic gasket after the deformation when inserting the pipe material, and at the same time cooperate with the sliding adaptation between the slider and the slide ring to limit the empty slot plate and avoid the empty slot plate from tilting, ensure the angle of the pipe material, avoid the pipe material from tilting during cutting, and make the pipe material cutting position wrong.

[0009] 3. The raw material cutting equipment for bearing race processing, through the cooperation of the rotating wheel and the side ring, when pulling the pipe material, the sliding friction force is converted into rotational friction force through the rotation of the rotating wheel, thereby reducing the resistance when pulling the pipe material and allowing the pipe material to move smoothly. At the same time, through the contact between the side ring and the surface of the pipe material, the contact area is reduced, thereby reducing the resistance when rotating the pipe material, allowing the pipe rotating mechanism to smoothly drive the pipe material to rotate, avoiding the rotation of the pipe material and the rotation of the pipe rotating mechanism being out of sync, resulting in reduced cutting effect.

[0010] 4. The raw material cutting equipment for processing the bearing race uses the elastic deformation of the elastic washer. When the side wheel and the inner top block contact the inner wall of the pipe, the contact pressure is transmitted to the conical cylinder through the inclined plate, and then transmitted to the elastic washer through the conical cylinder to buffer the contact pressure. While ensuring the fixing effect of the pipe, it avoids the inability to buffer the pressure when contacting the inner wall of the pipe, causing deformation of the pipe and affecting the quality of the pipe after cutting.

[0011] 5. The raw material cutting equipment for processing the bearing race uses the inclined surface of the inclined plate to make the inclined plate contact the pipe material when the axis position of the pipe material is not in the same straight line as the axis position of the empty groove barrel when entering the inner wall of the pipe material, so as to adjust the position of the pipe material to avoid the different contact pressures between the inner top block and the pipe material when the inner top block contacts the inner wall of the pipe material, which causes the pipe material to be tilted and pulled, resulting in damage.

DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0015] The first embodiment, as Figure 1 to Figure 2 and Figures 5 to 7 As shown, the present invention provides a technical solution: A raw material cutting device for bearing race processing, comprising: A frame 1, a laser gun 5 is fixedly mounted on the top of the frame 1, and a first cylinder 6 is fixedly mounted on one side of the top of the frame 1; A fixing mechanism 2, which is installed on the top of the frame 1, and is located on a side of the top of the frame 1 away from the first cylinder 6; The tube pulling mechanism 4 is installed on the top of the frame 1 near the first cylinder 6, and the axis of the tube pulling mechanism 4 is in the same plane as the axis of the fixing mechanism 2; A pipe rotating mechanism 3, which is installed on the top of the frame 1 and is located between the fixing mechanism 2 and the pipe pulling mechanism 4; The pipe rotating mechanism 3 includes an inclined groove plate 301, an inclined groove is provided on the outer side of the inclined groove plate 301, and a slide plate 306 is slidably installed at the inclined groove of the inclined groove plate 301. When the pipe cutting position corresponds to the position of the laser gun 5, the second cylinder 308 drives the slide plate 306 to slide in the inclined groove of the inclined groove plate 301, so that the turntable 305 is close to the pipe material. A motor 307 is fixedly connected to the outer side of the slide plate 306. The output end of the motor 307 passes through the slide plate 306 and extends to the other side, and the output end of the motor 307 is fixedly connected to the turntable 305. The center positions of both sides of the turntable 305 are provided with protrusions, and the inner ring 303 is fixedly installed on the protrusions of the turntable 305. A rubber strip 302 is fixedly installed on the outer side of the inner ring 303. The end of the rubber strip 302 away from the inner ring 303 is fixedly connected to the outer ring 304. The outer side of the outer ring 304 is fixedly connected to a rubber ring 310. The center position of the outer side of the turntable 305 is fixedly connected to When the outer cover ring 309 approaches, it first contacts the surface of the pipe material through the rubber ring 310, and in the process of continuous pressure, the rubber ring 310 and the rubber strip 302 are deformed, so that the center positions of the outer ring 304 and the inner ring 303 no longer overlap, and the center of the outer ring 304 is offset to the side away from the pipe material. After the outer cover ring 309 contacts the pipe material, the second cylinder 308 stops driving the slide plate 306 to move, and then the laser gun 5 emits a laser beam to cut the pipe material. At the same time, the motor 307 drives the turntable 305 to rotate, and when the turntable 305 rotates, the rubber ring 310 and the outer cover ring 309 are driven to rotate, and the pipe material is driven to rotate for cutting. The outer diameter of the outer cover ring 309 is smaller than the outer diameter of the rubber ring 310. Friction strips are arranged on the outer sides of the rubber ring 310 and the outer cover ring 309. The bottom of the inclined groove of the inclined groove plate 301 is fixedly connected with the second cylinder 308, and the output end of the second cylinder 308 is fixedly connected to the outer side of the slide plate 306.

[0016] The second embodiment is based on the first embodiment. Figure 3 to Figure 4As shown, the fixing mechanism 2 includes a slide groove ring 24, the number of which is two, and a connecting plate 22 is fixedly connected between the slide groove rings 24, and the connecting plate 22 is evenly installed along the center position of the slide groove ring 24, and a support frame 21 is fixedly connected to the outer side of the connecting plate 22, and the bottom of the support frame 21 is fixedly connected to the top of the frame body 1, and the inner wall of the slide groove ring 24 is evenly provided with a slide groove, and the worker inserts the pipe material from the inside of the slide groove ring 24 so that the surface of the pipe material contacts the side sleeve 27, and according to the outer diameter of the pipe material, the pipe material is squeezed outward, so that the side sleeve 27 transmits the pressure to the slider 23 through the runner 28 and the empty slot plate 26, so that the slider 23 compresses the elastic gasket 25, so that the elastic gasket 25 is deformed under pressure, and the slider 23 slides on the inner wall of the slide groove ring 24, and the pipe material between the runners 28 is clamped and fixed by the pressure generated by the deformation of the elastic gasket 25, and the slider 2 is slidably installed at the slide groove of the slide groove ring 24. 3. Elastic gaskets 25 are installed on the non-opposite surfaces of the slider 23. The elastic gaskets 25 are located between the slider 23 and the slide groove ring 24. Empty slot plates 26 are fixedly installed on the opposite surfaces of the slider 23. Empty slots are opened on the outer side of the empty slot plates 26, and circular slot plates 29 are fixedly installed on both ends of the empty slot plates 26. The circular slot plates 29 are evenly installed along the axial direction. In the process of the tube drawing mechanism 4 pulling the tube material, through the contact between the tube material and the side sleeve ring 27, the rotation connection between the rotating wheel 28 and the circular slot plate 29 is used to make the friction between the tube material and the fixing mechanism 2 a rotational friction force, so that the tube drawing mechanism 4 smoothly pulls the tube material to move. At the same time, when the tube material is rotated for cutting, the contact area is reduced and the friction is reduced through the contact between the side sleeve ring 27 and the tube material. Rotating wheels 28 are rotatably installed between the circular slot plates 29. The rotating wheel 28 is located at the empty slot of the empty slot plate 26, and the side sleeve rings 27 are fixedly installed on both ends of the outer side of the rotating wheel 28.

[0017] The third embodiment is based on the first and second embodiments. Figures 8 to 10 As shown, the tube pulling mechanism 4 includes a slide rail 401, which is symmetrically installed along the center position of the axis of the frame body 1, and the slide rail 401 is located on both sides of the first cylinder 6. A slide 402 is slidably installed on the top of the slide rail 401, and the bottom of the outer side of the slide 402 is fixedly connected to the output end of the first cylinder 6. When it is necessary to pull the tube to move, the first cylinder 6 drives the slide 402, so that the slide 402 is close to the tube under the restriction of the slide rail 401, so that the empty groove cylinder 405 enters the interior of the tube near the end of the laser gun 5. After entering the tube, the connecting rod 410 is driven to penetrate into the tube through the third cylinder 404. A fixed plate 403 is fixedly connected to the top of the slide 402, and a third cylinder 404 is fixedly connected to the center position of the fixed plate 403 away from the fixing mechanism 2. The output end of the third cylinder 404 passes through the fixed plate 403 and extends to the other side thereof.

[0018] The fixing plate 403 is fixedly connected to a hollow groove cylinder 405 at the center position near one side of the fixing mechanism 2, and arc grooves are evenly opened on the outside of the hollow groove cylinder 405. The output end of the third cylinder 404 is fixedly connected to a connecting rod 410, and the connecting rod 410 is located inside the hollow groove cylinder 405. The outside of the connecting rod 410 is fixedly connected to a fixing plate 411, and the outside of the fixing plate 411 is fixedly connected to an elastic cushion cylinder 412. When the connecting rod 410 moves, the connecting rod 410 drives the fixing plate 411, and drives the elastic cushion cylinder 412 and the conical cylinder 413 close to the inclined plate 414. When the conical cylinder 413 contacts the conical cylinder 413, the conical cylinder 413 drives the inclined plate 414 to slide on the inner wall of the chute plate 406 and expand outwards by utilizing the conical surface of the conical cylinder 413 in the process of approaching. In the process of expansion, the inner wall of the pipe material is contacted by the side wheels 409 and the inner top block 408 to fix the pipe material and the pipe drawing mechanism 4, so that when the first cylinder 6 drives the pipe drawing mechanism 4, the pipe material can be pulled to move. The side of the elastic cushion cylinder 412 away from the fixed plate 411 is fixedly connected with the conical cylinder 413, and the outer side of the conical cylinder 413 is a conical surface with an outer diameter gradually decreasing away from the fixed plate 411.

[0019] One end of the empty groove cylinder 405 close to the fixing mechanism 2 is fixedly connected to a slide groove plate 406, and the outer side of the slide groove plate 406 is fixedly connected to a conical block 407, and the conical block 407 is evenly installed along the center position of the slide groove plate 406. An inclined panel 414 is slidably installed on the inner wall of the slide groove plate 406, and the inclined panel 414 is evenly installed at the center position of the slide groove plate 406, and the opposite surface of the inclined panel 414 is matched with the conical surface of the conical cylinder 413, and the outer side of the inclined panel 414 is fixedly connected to an inner top block 408, and side wheels 409 are rotatably installed on both ends of the outer side of the inner top block 408.

[0020] When in use, the tubular raw material is placed in the fixing mechanism 2, and the tubular material is fixed and positioned by the fixing mechanism 2. Then, the first cylinder 6 drives the tube-drawing mechanism 4 close to one end of the tube material, so that the tube-drawing mechanism 4 enters one end of the tube material, and then the inside of the tube material is supported and fixed. Finally, driven by the first cylinder 6, the tube material is pulled by the tube-drawing mechanism 4 to move the tube material. When the cutting position of the tube material coincides with the position of the laser gun 5, the pulling is stopped, and the tube-drawing mechanism 4 releases the tube material and moves away from the tube material driven by the first cylinder 6. Then, the tube-turning mechanism 3 approaches the tube material and contacts it. When the laser gun 5 emits a laser beam for cutting, the tube material is driven to rotate by the tube-turning mechanism 3, so that the laser gun 5 performs a ring cutting on the tube material.

[0021] In the fixing mechanism 2, the worker inserts the pipe material from the inside of the slide groove ring 24 so that the surface of the pipe material contacts the side sleeve ring 27, and according to the outer diameter of the pipe material, the pipe material is squeezed outward, so that the side sleeve ring 27 transmits the pressure to the slider 23 through the rotating wheel 28 and the empty groove plate 26, so that the slider 23 compresses the elastic gasket 25, and the elastic gasket 25 is deformed under pressure, so that the slider 23 slides on the inner wall of the slide groove ring 24, and the pipe material between the rotating wheels 28 is clamped and fixed by the pressure generated by the deformation of the elastic gasket 25. At the same time, in the process of pulling the pipe material by the pipe drawing mechanism 4, through the contact between the pipe material and the side sleeve ring 27, the rotational connection between the rotating wheel 28 and the circular groove plate 29 is utilized to make the friction between the pipe material and the fixing mechanism 2 become the rotational friction force, so that the pipe drawing mechanism 4 can smoothly pull the pipe material to move, and at the same time, when the pipe material is rotated for cutting, the contact area is reduced and the friction force is reduced through the contact between the side sleeve ring 27 and the pipe material.

[0022] In the tube pulling mechanism 4, when it is necessary to pull the tube to move, the first cylinder 6 drives the slide 402, so that the slide 402 is close to the tube under the restriction of the slide rail 401, so that the empty groove cylinder 405 enters the interior of the tube near the end of the laser gun 5. After entering the interior of the tube, the third cylinder 404 drives the connecting rod 410 to go deeper into the tube. When the connecting rod 410 moves, the connecting rod 410 drives the fixing plate 411, and drives the elastic cushion cylinder 412 and the conical cylinder 413 to move. 413 approaches the inclined plate 414. When the inclined plate 414 contacts the conical cylinder 413, the conical surface of the conical cylinder 413 is utilized to drive the inclined plate 414 to slide on the inner wall of the slide plate 406 and expand outward during the approach process. In the process of expansion, the side wheels 409 and the inner top block 408 contact the inner wall of the pipe material, and the pipe material and the pipe drawing mechanism 4 are fixed, so that when the first cylinder 6 drives the pipe drawing mechanism 4, the pipe material can be pulled to move.

[0023] In the pipe rotating mechanism 3, when the pipe cutting position corresponds to the position of the laser gun 5, the second cylinder 308 drives the slide plate 306 to slide in the inclined groove of the inclined groove plate 301, so that the turntable 305 approaches the pipe. When approaching, the rubber ring 310 first contacts the surface of the pipe, and in the process of continuous pressure, the rubber ring 310 and the rubber strip 302 are deformed, so that the center positions of the outer ring 304 and the inner ring 303 no longer coincide, and the center of the outer ring 304 is offset to the side away from the pipe. After the outer cover ring 309 contacts the pipe, the second cylinder 308 stops driving the slide plate 306 to move, and then the laser gun 5 emits a laser beam to cut the pipe. At the same time, the motor 307 drives the turntable 305 to rotate. When the turntable 305 rotates, it drives the rubber ring 310 and the outer cover ring 309 to rotate, and drives the pipe to rotate for cutting.
