Description

Technical Field

[0001] This utility model relates to the field of metallurgical bearing processing technology, specifically to a metallurgical bearing ring production device for metallurgical bearing processing. Background Technology

[0002] Metallurgical bearings refer to rolling bearings used in the metallurgical industry. Rolling bearings generally consist of four parts: an outer ring, an inner ring, rolling elements, and a cage. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. Currently, during the production of metallurgical bearing rings, grinding is required. Grinding can remove defects such as machining marks and scratches from the surface of the bearing ring, making the surface smoother and flatter. Good surface finish can effectively reduce the coefficient of friction of the bearing during operation, reduce energy loss, and improve the working efficiency of the bearing.

[0003] A search revealed a bearing ring production device, application number CN202021807706.6. This device supports the inner wall of the bearing ring solely by the movement of clamps on both sides away from each other. When the grinding disc applies pressure to the surface of the bearing ring for grinding, this support method cannot provide sufficient stability for the bearing ring, causing it to easily move during the grinding process, affecting the grinding effect and precision. Moreover, when grinding the bearing ring, this device often requires grinding both sides of the bearing ring. The device is inconvenient for flipping the bearing ring, requiring workers to remove the bearing ring, manually flip it, and then place it back on the device for subsequent grinding, reducing production efficiency.

[0022] 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.

[0023] Please see Figure 1-5 As shown, a metallurgical bearing ring production device for metallurgical bearing processing includes a base plate 1. Fixing plates 2 are bolted to the left and right sides of the top of the base plate 1. Mounting brackets 3 are bolted to the top of one side surface of the fixing plates 2. A first motor 4 is fixed to the surface of the mounting bracket 3. One end of the output shaft of the first motor 4 passes through the fixing plate 2 and is fixed to a rotating plate 5. Electric push rods 6 are fixed to the front and back sides of the opposite side surface of the rotating plate 5. A clamping plate 7 is fixed to one end of the output shaft of the electric push rod 6. A support platform 8 is provided above the base plate 1. An adjustment structure 9 is movably connected to the bottom of the support platform 8. A fixing frame 10 is fixed to the back of the base plate 1. Hydraulic rods 17 are fixed to the left and right sides of the top of the fixing frame 10. The bottom end of the output shaft of the hydraulic rod 17 passes through the fixing frame 10 and is fixed to a lifting plate 18. A grinding device 11 is fixed below the lifting plate 18.

[0024] The adjustment structure 9 includes a mounting plate 91, a dual-axis motor 92, a threaded rod 93, a moving block 94, and a connecting rod 95. The mounting plate 91 is fixed to the center of the top of the base plate 1, and the dual-axis motor 92 is fixed to the center of the top of the mounting plate 91. The threaded rod 93 is rotatably connected to the lower part of the opposite side surface of the fixed plate 2, and one end of the threaded rod 93 is fixedly connected to the output shafts on the left and right sides of the dual-axis motor 92. The moving blocks 94 are located on the left and right sides above the mounting plate 91, and the connecting rod 95 is hinged to the top of the moving blocks 94. The threaded rod 93 passes through the moving blocks 94 and is threaded between the moving blocks 94 and the moving blocks 94. The threads on the left and right threaded rods 93 on the upper side of the mounting plate 91 are arranged in opposite directions. The connecting rod 95 is inclined as a whole, and the top of the connecting rod 95 is hinged to the bottom of the support platform 8. When the metallurgical bearing ring is being ground, the lower dual-axis motor 92 is turned on, which causes the threaded rods 93 on the left and right sides to rotate synchronously. The moving blocks 94 on the left and right sides move towards each other, causing the upper connecting rod 95 to move. The connecting rod 95 pushes the support platform 8 to rise, and the support platform 8 supports the bottom of the metallurgical bearing ring to ensure stable grinding in the future.

[0025] A limiting plate 12 is fixed to the top of the mounting plate 91, and a limiting block 13 is fixed to the bottom of the moving block 94. The limiting block 13 and the limiting plate 12 are slidably connected. When the threaded rod 93 rotates, the lower limiting block 13 can limit the upper moving block 94. The limiting block 13 slides above the limiting plate 12, so that the moving block 94 can only slide left and right.

[0026] The support platform 8 has grooves 14 on both the left and right sides, and the fixing plate 2 is slidably connected to the inner wall of the grooves 14. The front and rear surfaces of the fixing plate 2 are provided with guide grooves 15. The front and rear sides of the inner wall of the grooves 14 are fixed with guide blocks 16, and the guide blocks 16 are located inside the guide grooves 15 and are slidably connected to the inner wall of the guide grooves 15. When the support platform 8 moves up and down, the grooves 14, guide grooves 15 and guide blocks 16 are used to guide the support platform 8 as a whole, thereby improving the stability of the support platform 8 when it moves up and down.

[0027] The clamping plate 7 is generally arc-shaped, and anti-slip pads 19 are adhered to the surfaces of the clamping plate 7 on opposite sides. The anti-slip pads 19 are made of rubber and have anti-slip textures on their surfaces. When the clamping plate 7 clamps the metallurgical bearing ring to be ground, the anti-slip pads 19 can further improve the clamping effect on the metallurgical bearing ring and prevent the metallurgical bearing ring from falling off during grinding or flipping.

[0028] The front and rear sides of the support platform 8 are fixed with protective plates 20, and the surface of the protective plates 20 is provided with observation windows. When the workers are grinding, the support platform 8 rises and supports the bottom of the metallurgical bearing ring to improve the grinding stability. The protective plates 20 on the front and rear sides can protect the surrounding workers and prevent the flying debris from causing injury to the surrounding workers.

[0029] Working principle: When the operator needs to grind the metallurgical bearing ring, the operator first turns on the lower dual-axis motor 92, causing the support platform 8 to rise and fit against the bottom of the clamping plate 7. The operator then places the metallurgical bearing ring to be ground on the support platform 8 and opens the electric push rods 6 on both sides, causing the clamping plate 7 to clamp and fix the metallurgical bearing ring on the surface of the support platform 8. After clamping, the operator opens the hydraulic rod 17 to lower the grinding equipment 11. At this time, the operator opens the grinding equipment 11, allowing the grinding equipment 11 to grind the surface of the metallurgical bearing ring below. After grinding one side of the metallurgical bearing ring is completed, the operator... The operator opens the dual-axis motor 92 below, causing the support platform 8 to rise and move away from the clamping plate 7 and the metallurgical bearing ring. Then, the operator opens the first motors 4 on both sides, causing the first motors 4 to flip the rotating plate 5, which in turn causes the metallurgical bearing ring to flip as a whole. After that, the dual-axis motor 92 below opens again, causing the support platform 8 to continue to lift the bottom of the metallurgical bearing ring. Then, the operator can control the hydraulic rod 17 and the grinding equipment 11 to continue grinding the metallurgical bearing ring below. After the double-sided grinding of the metallurgical bearing ring is completed, the operator can remove the ground metallurgical bearing ring for subsequent production processing.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
