Description

Technical Field

[0001] This utility model relates to the field of bearing processing, and in particular to a turning device for bearing inner rings. Background Technology

[0002] Bearing performance requirements dictate that rotating bodies possess high runout accuracy, high-speed rotation, and minimal friction and frictional variation. Currently, machining of bearing inner rings necessitates the use of turning equipment. For instance, patent document CN220240058U discloses a high-precision turning device for bearing inner rings. Through the arrangement of sliding and movable structures, the bearing inner ring body is placed inside a groove. A hydraulic cylinder is activated, driving two L-shaped rods via hydraulic rods to move towards the outer walls of both ends of a through-hole. The movable cylinder also moves downwards on the outer wall of the connecting column via a support rod, connecting rod one, and pin seat two. This causes the two L-shaped rods to drive sliding blocks to slide within the sliding groove via connecting rod two, clamping and fixing the bearing inner ring body with two fixed blocks. The bearing inner ring is then machined using the turning structure. During the turning process, debris falls through through-hole one into a storage tank for collection.

[0003] However, for bearing inner rings of different sizes, the chips generated during the turning process do not fall directly into the storage tank through the through hole. Most of the chips still fall directly onto the top of the base, and then it is necessary to manually sweep the chips on the top of the base into the storage tank. This makes the above-mentioned turning device inconvenient to use and has poor versatility. Utility Model Content

[0004] The purpose of this invention is to provide a turning device for bearing inner rings in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A turning device for bearing inner rings includes a machine body, two side supports fixedly connected to the top of the machine body, a translation mechanism between the two side supports, a turning mechanism mounted on the translation mechanism, a turntable rotatably connected to the top of the machine body, a retaining ring fixedly connected to the top of the turntable, a spiral plate inside the retaining ring, the bottom of the spiral plate adhering to the turntable, the outermost end of the spiral plate adhering to the inner wall of the retaining ring, a chip removal pipe fixedly connected to the center bottom of the spiral plate, the chip removal pipe penetrating the turntable and the top wall of the machine body, the chip removal pipe rotatably connected to the turntable, and fixedly connected to the top wall of the machine body, a collection box inserted from the front end inside the machine body, the collection box being located below the chip removal pipe, a power mechanism for driving the turntable to rotate is mounted on one side of the machine body, and a clamping mechanism is mounted on the top of the turntable.

[0007] Preferably, the clamping mechanism includes two support plates fixedly connected to the top of the turntable, a guide rail fixedly connected between the two support plates, a bidirectional lead screw installed inside the guide rail, the bidirectional lead screw being rotatably connected to the support plates, two sliders being threadedly connected to the bidirectional lead screw, the sliders being slidably sleeved on the guide rail, and a V-shaped clamping plate fixedly connected to the top of the sliders.

[0008] Preferably, the top of the guide rail is set as an arc surface, and the inner bottom of the two V-shaped clamps is fixedly connected to a skirt.

[0009] Preferably, the power mechanism includes a second motor, which is fixedly connected to one side of the machine body. The output shaft of the second motor is fixedly connected to a gear, which meshes with a gear ring, which is fixedly connected to the outer circumference of the turntable.

[0010] Preferably, the translation mechanism includes a first motor, which is fixedly connected to one side of the side bracket. The output shaft of the first motor is fixedly connected to a translation screw, which is rotatably connected between the two side brackets. A translation seat is threaded onto the translation screw, and a guide rod is slidably connected inside the translation seat. The guide rod is fixedly connected between the two side brackets.

[0011] Preferably, the turning mechanism includes a hydraulic cylinder, which is fixedly connected to the top of the translation seat. A tool holder is fixedly connected to the output end of the hydraulic cylinder, and a turning tool is fixedly connected to the bottom of the tool holder.

[0012] The beneficial effects are as follows: During the turning process, the turntable rotates while the volute plate remains stationary. The chips on the turntable move with the turntable, and under the obstruction and guidance of the volute plate, the chips are gradually pushed to the central chip discharge pipe. The chips fall into the collection box through the chip discharge pipe, realizing automatic chip collection without manual cleaning, making it more convenient to use. For bearing inner rings of different diameters, as long as the diameter of the bearing inner ring is smaller than the diameter of the retaining ring, it can be ensured that the chips fall into the area covered by the volute plate, thus adapting to a wider range of bearing inner ring sizes and making it more versatile.

Therefore, they should not be construed as limitations on this utility model.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-7As shown, a turning device for bearing inner rings includes a machine body 1. Two side supports 2 are welded to the top of the machine body 1, and a translation mechanism 3 is arranged between the two side supports 2. A turning mechanism 4 is mounted on the translation mechanism 3. A turntable 101 is rotatably connected to the top of the machine body 1. A retaining ring 102 is fixedly connected to the top of the turntable 101. A spiral plate 104 is arranged inside the retaining ring 102. The bottom of the spiral plate 104 is attached to the turntable 101, and the outermost end of the spiral plate 104 is attached to the inner wall of the retaining ring 102. A chip removal pipe 103 is fixedly connected to the bottom center of the spiral plate 104. The chip removal pipe 103 penetrates the turntable 101 and the top wall of the machine body 1, is rotatably connected to the turntable 101, and is fixedly connected to the top wall of the machine body 1. When the turntable 101 rotates, the chip removal pipe 103 and the volute plate 104 remain stationary. The chips generated during turning fall onto the turntable 101 and are located inside the retaining ring 102. The rotation of the turntable 101 will drive the chips to move. The volute plate 104 blocks and guides the chips, causing them to gradually move to the center of the volute plate 104 and fall into the chip removal pipe 103. A collection box 105 is inserted into the machine body 1 from the front end. The collection box 105 is located below the chip removal pipe 103. The chips fall into the collection box 105 through the chip removal pipe 103. The operator can pull the collection box 105 out of the machine body 1 to process the chips. A power mechanism 5 for driving the turntable 101 to rotate is provided on one side of the machine body 1, and a clamping mechanism 6 is provided on the top of the turntable 101.

[0027] The clamping mechanism 6 includes two support plates 601 welded to the top of the turntable 101. A guide rail 602 is fixedly connected between the two support plates 601. A bidirectional lead screw 603 is installed inside the guide rail 602. The bidirectional lead screw 603 is rotatably connected to the support plates 601. Two sliders 604 are threadedly connected to the bidirectional lead screw 603. The sliders 604 are slidably sleeved on the guide rail 602. A handle is fixedly connected to one end of the bidirectional lead screw 603. When the bidirectional lead screw 603 is rotated by the handle, it will drive the two sliders 604 to move closer or further apart. A V-shaped clamping plate 605 is fixedly connected to the top of the sliders 604. The sliders 604 drive the V-shaped clamping plate 605 to move and clamp the inner ring of the bearing.

[0028] The top of the guide rail 602 is designed as an arc surface, so that the chips during the turning process will not accumulate on the top of the guide rail 602. The inner bottom of the two V-shaped clamps 605 are fixedly connected to the skirt 606. When turning the bearing inner ring of the same size, the two V-shaped clamps 605 can be kept at a suitable distance, so that the bearing inner ring can be placed directly on the skirt 606. Then, the two V-shaped clamps 605 are brought close together to clamp the bearing inner ring. The skirt 606 facilitates the placement of the bearing inner ring.

[0029] The power mechanism 5 includes a second motor 501, which is fixedly connected to one side of the machine body 1 via a motor mount. The output shaft of the second motor 501 is fixedly connected to a gear 502, which meshes with a gear ring 503. The gear ring 503 is fixedly connected to the outer circumference of the turntable 101.

[0030] The translation mechanism 3 includes a first motor 301, which is bolted to one side of the side bracket 2. The output shaft of the first motor 301 is fixedly connected to a translation screw 302, which is rotatably connected between the two side brackets 2. A translation seat 303 is threaded onto the translation screw 302, and a guide rod 304 is slidably connected inside the translation seat 303. The guide rod 304 is connected between the two side brackets 2 by screws.

[0031] The turning mechanism 4 includes a hydraulic cylinder 401, which is fixedly connected to the top of the translation seat 303 by screws. The output end of the hydraulic cylinder 401 is fixedly connected to a tool holder 402, and the bottom of the tool holder 402 is fixedly connected to a turning tool 403.

[0032] Working principle: In use, the bearing inner ring is placed between two V-shaped clamps 605 and on the skirt plate 606. Then, the double-acting screw 603 is rotated, driving two sliders 604 to move closer. The sliders 604 move the V-shaped clamps 605 to clamp the bearing inner ring. The hydraulic cylinder 401 drives the tool holder 402 and the cutting tool 403 to move downwards. Then, the first motor 301 drives the translation screw 302 to rotate, which in turn drives the translation seat 303 to move, causing the cutting tool 403 to move and adhere to the inner wall of the bearing inner ring. The second motor 501 drives the gear 502 to rotate, which in turn drives the gear ring 503 to rotate. The gear ring 503 drives the turntable 101 to rotate. 1 drives the clamping mechanism 6 to rotate, thereby causing the inner ring of the bearing to rotate. The cutting tool 403 performs turning machining on the inner ring of the bearing. During the turning process, the chips generated fall onto the turntable 101 and are located inside the retaining ring 102. When the turntable 101 rotates, the chip removal pipe 103 and the volute plate 104 remain stationary. The chips generated during turning fall onto the turntable 101 and are located inside the retaining ring 102. The rotation of the turntable 101 will drive the chips to move. The volute plate 104 blocks and guides the chips, causing the chips to gradually move to the center of the volute plate 104 and fall into the chip removal pipe 103. The chips fall into the collection box 105 through the chip removal pipe 103. The operator can pull the collection box 105 out of the machine body 1 to process the chips.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
