Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, and in particular to a bearing ring double-end face grinding device. Background Technology

[0002] Bearing rings are an indispensable and important component of bearings. During the bearing production process, bearing rings need to be ground to a flat state to ensure the stability of the bearing during use. Therefore, grinding equipment is required to grind the bearing rings.

[0003] A search revealed a Chinese patent (publication number: CN120155819B) disclosing a device for grinding the end face of motor bearing rings. The device includes a main body with an internal movable cavity at its top. A grinding mechanism is installed in the internal movable cavity to drive the bearing rings to rotate and grind them. The grinding mechanism includes three connecting rods, each with a fourth gear mounted at its other end. The three connecting rods drive the corresponding fourth gears to rotate. A connecting shaft is installed at the eccentric point on the surface of each of the three fourth gears. A rotating mechanism is installed on the top of each of the three fourth gears for grinding the bearing rings from the inside out. In use, multiple bearing rings are placed on the corresponding mounting openings 54. The first motor 23 is then started, and its output shaft drives the elliptical plate to rotate. The first gear 24 located at the position of the first motor 23 remains stationary. With the meshing of two first gears 24, the other first gear 24 rotates. Subsequently, the second metal frame 25 rotates the two top grinding discs 26 until they cover the main body 11. The second motor 31 is then started, driving the second gear 33 at the top of the drive shaft 32 to rotate, thereby rotating the outer ring rotating layer 34 connected to the gear ring 36. Due to the limiting action of multiple second limiting blocks 35 and corresponding first limiting blocks 27, the top grinding disc 26 rotates to grind the top of the bearing rings. Simultaneously, as the second gear 33 rotates, it drives the inner wall of the third gear 42... When the cylinder 41 rotates, the three connecting rods 43 on it will rotate. When the three connecting rods 43 rotate, the three fourth gears 44 will rotate accordingly, thus realizing the rotational grinding of the bearing ring. In addition, the connecting shaft 46 on it rotates eccentrically. When the connecting shaft 46 moves eccentrically, as the connecting shaft 46 moves to the side close to the fixed column 13, the two adjacent connecting columns 51 will move closer to the corresponding fixed ring 52 and move away from the fixed column 13, thus realizing the transverse grinding of the bearing ring. When the fixed ring 52 moves outward, the multiple second meshing columns 55 on the mounting platform 53, which is rotated on its inner wall, will mesh with the corresponding meshing teeth 56. During the revolution, the mounting platform 53 will rotate, thus completing the face-changing operation of the multiple bearing rings on the mounting platform 53. At this point, the grinding process of the bearing ring ends.

[0004] In this application, a rotatable top grinding disc is used to contact the upper surface of the bearing ring placed in the mounting opening. Simultaneously, the grinding table and the top grinding disc work together to perform double-end grinding on both the upper and lower surfaces of the bearing ring. However, the top grinding disc in this application rotates at a fixed angle. This results in the top grinding disc remaining in a fixed position when it rotates to a state parallel to the grinding table. When grinding bearing rings of different thicknesses, the fixed angle prevents the top grinding disc from maintaining parallelism with the upper surface of the ring, making it difficult to grind bearing rings of different thicknesses. This results in poor applicability and room for improvement. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a double-end face grinding device for bearing rings.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A bearing ring double-end face grinding device includes a support platform. Support frames are fixedly connected to both sides of the support platform. Support rods are fixedly connected to the opposite faces of the two support frames. Clamping assemblies are fixedly connected to the opposite ends of the two support rods. A fixing groove is formed on the upper surface of the support platform. A bottom grinding assembly is fixedly connected to the inner bottom wall of the fixing groove. A top grinding assembly is fixedly connected to the upper surface of the two support frames. The clamping assembly includes a circular frame with openings at the top and bottom. A positioning frame is fixedly connected to the inner wall of the circular frame. Five clamping mechanisms are fixedly connected to the positioning frame. The positioning frame suspends and fixes the five clamping frames within the circular frame, ensuring that the circular frame does not contact the top and bottom grinding assemblies, while also ensuring the effective fixing of the bearing ring.

[0008] Preferably, the clamping mechanism includes a clamping frame with an open top and bottom. The surface of the clamping frame is threaded with two adjusting screws, and the opposite ends of the two adjusting screws are rotatably connected to arc-shaped clamping plates.

[0009] Preferably, two through holes are provided on the surface of the clamping frame at positions corresponding to the two adjusting screws. Limiting rods are slidably connected to the inner walls of the two through holes. The end of the limiting rod near the inside of the clamping frame is fixedly connected to the arc-shaped clamping plate. Rotating the two adjusting screws can drive the two arc-shaped clamping plates to move closer to each other, thereby fixing the collar in the clamping frame. The limiting rods also ensure that the arc-shaped clamping plates will not rotate or shift when moving.

[0010] Preferably, the bottom grinding assembly includes a first motor, the output end of which is fixedly connected to a connecting shaft, and the top end of the connecting shaft is fixedly connected to a bottom grinding disc. The size of the bottom grinding disc is the same as that of the circular frame. The first motor can drive the bottom grinding disc to rotate through the connecting shaft, thereby grinding the lower surface of the fixed ring.

[0011] Preferably, the top grinding assembly includes two second motors, each with a threaded rod fixedly connected to its output end. Slide grooves are formed on the opposite surfaces of the two support frames, and sliders are slidably connected to the inner walls of the two slide grooves. Transmission rods are fixedly connected to the opposite surfaces of the two sliders, and movable frames are fixedly connected to the opposite ends of the two transmission rods. The second motors drive the threaded rods to rotate, which in turn drives the transmission blocks to move downwards, thereby causing the movable frames to move downwards.

[0012] Preferably, the bottom ends of the two threaded rods are rotatably connected to the inner bottom walls of the two slides, and the two sliders are threadedly connected to the two threaded rods. A third motor is fixedly connected to the upper surface of the movable frame, and a transmission shaft is fixedly connected to the output end of the third motor. A top grinding disc is fixedly connected to the bottom end of the transmission shaft. The height of the top grinding disc can be freely adjusted, so that the position of the top grinding disc can be changed according to the thickness of the collar.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Through the coordinated arrangement of the clamping assembly, the bottom grinding assembly, and the top grinding assembly, five clamping frames can simultaneously suspend and fix five rings within a circular frame during use, with the bottom in contact with the bottom grinding disc. The second motor, via a threaded rod, drives the slider and the support rod to move the movable frame downward, allowing the top grinding disc to contact the upper surface of the rings. This enables simultaneous grinding of both the upper and lower surfaces of the five rings, improving the processing and grinding efficiency of the rings. It also allows for free adjustment of the downward movement distance of the top grinding disc, facilitating adjustments based on rings of different thicknesses and providing high flexibility.

[0015] 2. By setting up the positioning frame, five clamping frames can be suspended and fixed inside the circular frame, ensuring that the clamping components will not contact the top and bottom grinding discs. At the same time, by using the adjusting screw to drive the two arc-shaped clamping plates to move closer to each other, the ferrule can be locked in the suspended position inside the clamping frame, ensuring the stability of the ferrule during the grinding process. It can also clamp ferrules of different sizes. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, referring to Figure 1-4 A bearing ring double-end face grinding device includes a support platform 1, support frames 2 are fixedly connected to both the left and right sides of the support platform 1, support rods 3 are fixedly connected to the opposite faces of the two support frames 2, clamping components 4 are fixedly connected to the opposite ends of the two support rods 3, a fixing groove is opened on the upper surface of the support platform 1, a bottom grinding component 5 is fixedly connected to the inner bottom wall of the fixing groove, a top grinding component 6 is fixedly connected to the upper surface of the two support frames 2, and the clamping component 4 includes a circular frame 401, the circular frame 401 has an open structure at the top and bottom, a positioning frame 402 is fixedly connected to the inner wall of the circular frame 401, and five clamping mechanisms are fixedly connected to the positioning frame 402.

[0023] The clamping mechanism includes a clamping frame 403, which has an open structure at the top and bottom. Two adjusting screws 404 are threadedly connected to the surface of the clamping frame 403. Arc-shaped clamping plates 405 are rotatably connected to the opposite ends of the two adjusting screws 404. Two through holes are opened on the surface of the clamping frame 403 at positions corresponding to the two adjusting screws 404. Limiting rods 406 are slidably connected to the inner walls of the two through holes. One end of the limiting rod 406 near the inside of the clamping frame 403 is fixedly connected to the arc-shaped clamping plate 405.

[0024] The positioning frame 402 can fix the five clamping frames 403 to the inner wall of the circular frame 401, making the clamping frames 403 suspended and stable, ensuring that the clamping assembly 4 will not contact the top grinding assembly 6 and the bottom grinding assembly 5. In addition, by rotating the two adjusting screws 404, the two arc-shaped clamping plates 405 can be driven to move closer to each other until the two arc-shaped clamping plates 405 clamp the ring at the center position of the clamping frame 403. Due to the limiting effect of the limiting rod 406, the arc-shaped clamping plates 405 will not deviate or rotate while being driven by the adjusting screws 404, resulting in higher stability. At the same time, the five rings can be processed synchronously, improving the processing and grinding efficiency of the rings.

[0025] Example 2: The bottom grinding assembly 5 includes a first motor 501, the output end of which is fixedly connected to a connecting shaft 502. The top end of the connecting shaft 502 is fixedly connected to a bottom grinding disc 503. The size of the bottom grinding disc 503 is the same as that of the circular frame 401. The top grinding assembly 6 includes two second motors 601, the output ends of which are fixedly connected to threaded rods 602. The opposing surfaces of the two support frames 2 are provided with sliding grooves, and the inner walls of the two sliding grooves are slidably connected to sliders 6. 03. A transmission rod 604 is fixedly connected to the opposite face of the two sliders 603. A movable frame 605 is fixedly connected to the opposite end of the two transmission rods 604. The bottom ends of the two threaded rods 602 are rotatably connected to the inner bottom wall of the two slides respectively. The two sliders 603 are threadedly connected to the two threaded rods 602 respectively. A third motor 606 is fixedly connected to the upper surface of the movable frame 605. A transmission shaft 607 is fixedly connected to the output end of the third motor 606. A top grinding disc 608 is fixedly connected to the bottom end of the transmission shaft 607.

[0026] The first motor 501 and the third motor 606 can drive the bottom grinding disc 503 and the top grinding disc 608 to rotate simultaneously via the connecting shaft 502 and the transmission shaft 607. Since the second motor 601 can drive the slider 603 to move downward via the threaded rod 602, it can drive the movable frame 605 to move downward via the two transmission rods 604 until the lower surface of the top grinding disc 608 contacts the upper surface of the ring. After the bottom grinding disc 503 and the top grinding disc 608 rotate, they can simultaneously grind the upper and lower surfaces of the ring, thereby further improving the grinding efficiency of the ring.

[0027] In addition, it should be noted that the downward position of the top grinding disc 608 can be freely adjusted according to the thickness of the ferrule, making it suitable for ferrules of different thicknesses and offering high flexibility.

[0028] Working principle: First, the ring to be processed is placed in each clamping frame 403, with the bottom of the ring contacting the upper surface of the bottom grinding disc 503. Then, the adjusting screws 404 on both sides of the clamping frame 403 are rotated. The adjusting screws 404 drive the two arc-shaped clamping plates 405 to move closer together, thus clamping and fixing the ring within the clamping frame 403. Because the arc-shaped clamping plates 405 are limited by the two limiting rods 406, there will be no offset rotation. Then, the two second motors 601 are activated. The two second motors 601 drive the two sliders 603 to move downwards synchronously via the two threaded rods 602. This, in turn, drives the movable frame 605 downwards via the transmission rod 604 until the movable frame 605 is driven... The top grinding disc 608 contacts the upper surface of the bearing ring. At this time, the first motor 501 and the third motor 606 are turned on. Through the connecting shaft 502 and the transmission shaft 607, the bottom grinding disc 503 and the top grinding disc 608 can be driven to rotate simultaneously, thereby enabling simultaneous grinding of both ends of the bearing ring. This allows for simultaneous grinding of both ends of the bearing ring and the grinding of multiple bearing rings, greatly improving the grinding efficiency of bearing rings. Furthermore, through the arrangement of the second motor 601, the threaded rod 602, and the slider 603, the position of the top grinding disc 608 can be adapted to the upper surface of the bearing ring according to its actual thickness. Therefore, it is applicable to bearing rings of different thicknesses and offers high flexibility.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
