Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, specifically a trimming device for processing thrust bearings. Background Technology

[0002] Thrust bearings are used to carry axial loads. They are also known as axial bearings. Similar to radial bearings, thrust bearings consist of two raceways, a set of rolling elements, and a cage to hold the rolling elements. Thrust bearings require trimming of the outer raceway sidewalls during machining.

[0003] Existing trimming devices for thrust bearing processing typically involve fixing the bearing to a fixture, bringing a rotating grinding head close to the outer surface of the bearing, and then making the grinding head rotate around the bearing to complete the trimming and grinding work. However, this trimming method requires high precision in the movement trajectory of the grinding head; even slight deviations can affect the trimming quality. Therefore, a new trimming device for thrust bearing processing is proposed. Utility Model Content

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, a trimming device for processing thrust bearings includes a processing table 1. A support frame 2 is fixedly installed at the bottom of the processing table 1, and a first fixing plate 3 is fixedly installed at the upper end of the processing table 1. A fixing column 4 is provided on the side wall of the first fixing plate 3. A driving mechanism is provided between the fixing column 4 and the first fixing plate 3. A grinding mechanism acting on the thrust bearing is provided above the fixing column 4. A fixing mechanism acting on the thrust bearing is provided on the fixing column 4. The fixing mechanism consists of a trapezoidal block 16 and a slider 14. A movable groove 13 is opened inside the fixing column 4. A slider 14 is slidably installed in the movable groove 13. There are four trapezoidal blocks 16, which are arranged in a circular array around the fixed column 4. One end of the trapezoidal block 16 penetrates the side wall of the fixed column 4 and extends into the interior of the movable groove 13. The end of the trapezoidal block 16 near the slider 14 is an inclined surface. The four side walls of the slider 14 near the trapezoidal block 16 are all set as inclined mating surfaces 19. The four mating surfaces 19 are parallel to the inclined surfaces of the four trapezoidal blocks 16. An adjustment mechanism acting on the slider 14 is provided on the fixed column 4.

[0021] The movable groove 13 is a rectangular groove, and the four trapezoidal blocks 16 correspond one-to-one with the four inner walls of the movable groove 13.

[0022] The adjustment mechanism consists of an adjustment component 12 and a lead screw 15. The two ends of the lead screw 15 are rotatably connected to the inner walls of the two sides of the movable groove 13. The lead screw 15 passes through the slider 14 and is connected to the slider 14 by threaded engagement. The adjustment component 12 is rotatably installed on the outer wall of the fixed column 4 and is fixedly connected to the lead screw 15.

[0023] In use, the thrust bearing is fitted onto the outer surface of the fixed column 4. Rotating the adjusting component 12 causes the lead screw 15 to rotate, thereby causing the slider 14 to slide in the movable groove 13. The slider 14 is controlled to move towards the trapezoidal block 16. The mating surface 19 on the slider 14 will press against the inclined surface on the trapezoidal block 16, thereby squeezing the trapezoidal block 16 out of the movable groove 13. The protruding end of the trapezoidal block 16 will abut against the inner ring sidewall of the thrust bearing. The four trapezoidal blocks 16 work together to fix the thrust bearing.

[0024] The adjusting component 12 has multiple anti-slip seams on its outer wall, and these seams are arranged in a ring array.

[0025] The anti-slip seams can increase the friction between the worker's hands and the adjusting component 12.

[0026] The drive mechanism consists of a first motor 5 and a rotating disk 11. The rotating disk 11 is rotatably mounted on the side wall of the first fixed plate 3. The fixed column 4 is fixedly connected to the center of the shaft end of the rotating disk 11. The first motor 5 is fixedly mounted on the end of the first fixed plate 3 away from the rotating disk 11. The output shaft of the first motor 5 is fixedly connected to the rotating disk 11.

[0027] In use, the first motor 5 can drive the rotating disk 11 to rotate, thereby driving the fixed column 4 to rotate.

[0028] Among them, a baffle 17 is fixedly installed at one end of the trapezoidal block 16 inside the movable groove 13, and a spring 18 is fixedly connected between the baffle 17 and the inner wall of the movable groove 13.

[0029] The trapezoidal block 16 can be limited by the baffle 17 and spring 18 to prevent it from separating from the fixed post 4.

[0030] The grinding mechanism consists of a second fixed plate 6, a cylinder 7, a lifting plate 8, a grinding head 9, and a second motor 10. The second fixed plate 6 is fixedly installed on the upper end of the processing table 1. The cylinder 7 is fixedly installed on the upper end of the second fixed plate 6. The lifting plate 8 is fixedly connected to the end of the telescopic rod of the cylinder 7. The lifting plate 8 is vertically set. The second motor 10 is fixedly installed on one end of the lifting plate 8. The grinding head 9 is rotatably installed on the other end of the lifting plate 8. The output shaft of the second motor 10 is fixedly connected to the grinding head 9. The grinding head 9 is located above the trapezoidal block 16.

[0031] In use, the second motor 10 can drive the grinding head 9 to rotate. By controlling the length of the telescopic rod of the cylinder 7, the height of the grinding head 9 can be adjusted. The grinding head 9 is controlled to move downward and contact the thrust bearing, so that the thrust bearing can be trimmed and ground.

[0032] This utility model provides a trimming device for processing thrust bearings, the specific working principle of which is as follows:

[0033] In use, the thrust bearing is fitted onto the outer surface of the fixed column 4. Rotating the adjusting component 12 causes the lead screw 15 to rotate, thereby causing the slider 14 to slide within the movable groove 13. Controlling the slider 14 to move towards the trapezoidal block 16, the mating surface 19 on the slider 14 presses against the inclined surface on the trapezoidal block 16, thus squeezing the trapezoidal block 16 out of the movable groove 13. The protruding end of the trapezoidal block 16 abuts against the inner ring sidewall of the thrust bearing. The four trapezoidal blocks 16 work together to fix the thrust bearing. Then, the first motor 5 is started to rotate. The disc 11, the fixed column 4, and the thrust bearing rotate. Then, the second motor 10 is started to drive the grinding head 9 to rotate and extend the length of the telescopic rod of the cylinder 7. This controls the grinding head 9 to move downward and contact the rotating thrust bearing, thus trimming and grinding the thrust bearing. The fixing method of this device can center the thrust bearing and ensure that the top of the thrust bearing is always in the same position. In this way, the grinding head 9 can be moved to the same position each time, which can reduce the processing difficulty and improve the processing accuracy to a certain extent.

[0034] 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.
