Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, and in particular to a bearing inner groove grinding machine. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. Both the outer and inner rings of a bearing have internal grooves, and the main function of these internal grooves is to provide a track for the rolling elements, allowing them to roll evenly within the bearing.

[0003] However, in the existing technology, the inner grooves on the outer and inner rings of the bearing need to be ground during the bearing production process to remove the roughness and unevenness of the inner groove surface and make it smooth so that the rolling elements can roll smoothly on it. However, most grinding machines can only grind one of the outer and inner rings of the bearing in a single grinding process, which means that two grinding processes are required to smooth the inner groove of a bearing, resulting in low grinding efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies: most grinding machines can only grind one of the outer ring and inner ring of a bearing in a single grinding process, which requires two grinding operations to smooth the inner groove of a bearing, resulting in low grinding efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bearing inner groove grinding machine, comprising a mounting plate, a motor fixedly connected to one side surface of the mounting plate, and an output shaft fixedly connected to the output end of the motor, a first grinding component and a second grinding component fixedly connected to the surface of the output shaft, a bearing outer ring placed at one end of the first grinding component, a first electric telescopic rod fixedly connected to both the left and right ends of one side of the mounting plate, and a pressing arc plate fixedly connected to one end of the first electric telescopic rod, a second electric telescopic rod fixedly connected to the bottom surface of the mounting plate, a movable frame fixedly connected to one end of the second electric telescopic rod, a third electric telescopic rod fixedly connected to the surface of the movable frame, a hanging plate fixedly connected to the top of the movable frame, a pressure plate fixedly connected to one end of the third electric telescopic rod, and a bearing inner ring engaged on the hanging plate and the pressure plate.

[0006] In a preferred embodiment, a positioning arc plate is fixedly connected to one side surface of the mounting plate at a position below the output shaft.

[0007] In a preferred embodiment, a baffle is fixedly connected to one side surface of the extrusion arc plate.

[0008] In a preferred embodiment, both the hanging plate and the pressure plate have anti-slip textures on one side surface.

[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0010] This invention uses a first electric telescopic rod and a pressing arc plate to clamp and fix the outer ring of the bearing on one side of the mounting plate, stabilizing the output shaft at the center of the outer ring and bringing the first grinding component into contact with the inner groove of the outer ring. The inner ring is then mounted on the mounting plate. The third electric telescopic rod retracts, causing the pressure plate to move downwards and engage with the inner ring, continuously pressing it to fix it to one side of the moving frame. The second electric telescopic rod retracts, moving the entire moving frame towards the location of the second grinding component. When the second electric telescopic rod is fully retracted, the inner groove of the inner ring contacts the second grinding component, placing the output shaft at the center of the inner ring. The motor drives the output shaft to rotate, causing the first and second grinding components to move around the inner grooves of both the outer and inner rings, simultaneously grinding both inner grooves and effectively improving grinding efficiency.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1

[0019] like Figures 1-4As shown, this utility model provides a technical solution: a bearing inner groove grinding machine, including a mounting plate 1, a motor 2 fixedly connected to one side surface of the mounting plate 1, and an output shaft 3 fixedly connected to the output end of the motor 2. A first grinding piece 4 and a second grinding piece 5 are fixedly connected to the surface of the output shaft 3. The output shaft 3 is driven to rotate by the motor 2, thereby causing the first grinding piece 4 and the second grinding piece 5 to move in a circular motion around the output shaft 3. When the output shaft 3, the bearing outer ring 6, and the bearing inner ring 16 are at the same center and the first grinding piece 4 and the second grinding piece 5 are in contact with the inner groove of the bearing outer ring 6 and the bearing inner ring 16, the first grinding piece 4 and the second grinding piece 5 are ground together. 5. By making a circular motion around the output shaft 3, the inner grooves of the bearing outer ring 6 and the bearing inner ring 16 can be ground simultaneously, effectively improving the grinding efficiency. One end of the first grinding part 4 is placed with the bearing outer ring 6. The left and right ends of one side of the mounting plate 1 are fixed with electric telescopic rods 8, and one end of the first electric telescopic rod 8 is fixedly connected to the extrusion arc plate 9. The extension and retraction of the first electric telescopic rod 8 drives the extrusion arc plate 9 to move. When one side of the bearing outer ring 6 is in contact with the vertical surface of the mounting plate 1, and the bearing outer ring 6 and the output shaft 3 are at the same center, the first grinding part 4 will be in contact with the inner groove of the bearing outer ring 6. At this time, the first grinding part 4 at both ends of the mounting plate 1 will be ground. Simultaneously, the electric telescopic rod 8 extends, driving the two extrusion arc plates 9 to move towards the outer ring 6 of the bearing and clamp and fix it, effectively preventing the outer ring 6 of the bearing from moving freely, ensuring that the first grinding part 4 can perform stable grinding processing on the inner groove of the outer ring 6 of the bearing. The second electric telescopic rod 11 is fixed on the bottom surface of the mounting plate 1, and a movable frame 12 is fixed to one end of the second electric telescopic rod 11. The third electric telescopic rod 13 is fixed on the surface of the movable frame 12, and a hanging plate 14 is fixed to the top of the movable frame 12. A pressure plate 15 is fixed to one end of the third electric telescopic rod 13, and the inner ring 16 of the bearing is engaged and connected to the hanging plate 14 and the pressure plate 15. The inner ring 16 of the bearing is hung and clamped on the hanging plate 1. 4. Then, retract the third electric telescopic rod 13 to move the pressure plate 15 down, so that it engages with the inner ring 16 of the bearing and continuously presses the inner ring 16 of the bearing, fixing the inner ring 16 of the bearing to one side of the moving frame 12, ensuring the stability of the inner ring 16 of the bearing during subsequent grinding. By retracting the second electric telescopic rod 11, the moving frame 12 is moved as a whole towards the location of the second grinding part 5. When the second electric telescopic rod 11 is fully retracted, the inner groove of the inner ring 16 of the bearing, which moves with the moving frame 12, will contact the second grinding part 5, and the output shaft 3 will be located at the center position on one side of the inner ring 16 of the bearing, which will facilitate the subsequent grinding of the inner groove of the inner ring 16 of the bearing by the second grinding part 5.

[0020] Example 2

[0021] like Figures 1-4As shown, a positioning arc plate 7 is fixedly connected to one side surface of the mounting plate 1, located below the output shaft 3. By placing the lower end of the bearing outer ring 6 on the positioning arc plate 7, the concentric position between the bearing outer ring 6 and the output shaft 3 can be quickly located. A baffle 10 is fixedly connected to one side surface of the pressing arc plate 9. When the pressing arc plate 9 clamps and fixes the bearing outer ring 6, the baffle 10 prevents the bearing outer ring 6 from moving forward, further preventing the bearing outer ring 6 from moving during grinding. One side surface of the hanging plate 14 and the pressure plate 15 are provided with anti-slip texture. The anti-slip texture increases the friction between the hanging plate 14 and the pressure plate 15 and the bearing inner ring 16, thereby improving the stability of the bearing inner ring 16 being pressed and fixed at the hanging plate 14 and the pressure plate 15, which facilitates the subsequent grinding of the inner groove of the bearing inner ring 16.

[0022] Working principle:

[0023] like Figures 1-4 As shown, when using this utility model, the user first takes out the outer ring 6 of the bearing and moves it so that the output shaft 3, the first grinding part 4, and the second grinding part 5 pass through the hollow part in the middle of the outer ring 6 of the bearing, and makes one side of the outer ring 6 of the bearing fit against the vertical surface of the mounting plate 1. Then, the lower end of the outer ring 6 of the bearing is placed on the positioning arc plate 7, so that the output shaft 3 and the outer ring 6 of the bearing are at the same center position, and the first grinding part 4 contacts the inner groove of the outer ring 6 of the bearing. Then, the two first electric telescopic rods 8 are extended at the same time to drive the extrusion arc plate 9 to move towards the outer surface of the outer ring 6 of the bearing. Then, the extrusion arc plate 9 clamps and fixes the outer ring 6 of the bearing, and the baffle 10 blocks and limits the outer ring 6 of the bearing. Then, the inner ring 16 of the bearing is taken out and its upper end is hung on the hanging plate 14. Then, the third electric telescopic rod 13 is retracted, so that the pressure plate 15 is lowered. Press down on the lower end of the inner surface of the bearing inner ring 16 to fix it on the hanging plate 14 and the pressure plate 15. Then, retract the second electric telescopic rod 11 to move the entire moving frame 12 toward the location of the second grinding part 5. When the second electric telescopic rod 11 is fully retracted, the inner groove of the bearing inner ring 16, which moves with the moving frame 12, will contact the second grinding part 5, and the output shaft 3 will be positioned at the center of one side of the bearing inner ring 16. Then, start the motor 2 to drive the output shaft 3 to rotate. The rotation of the output shaft 3 will cause the first grinding part 4 and the second grinding part 5 to move around the center of the output shaft 3, so that the first grinding part 4 and the second grinding part 5 can grind the inner groove of the bearing outer ring 6 and the bearing inner ring 16 at the same time, saving time and improving the efficiency of grinding.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
