Description

Technical Field

[0001] This invention relates to the field of bearing processing technology, and more particularly to a precision bearing grinding apparatus for aerospace applications. Background Technology

[0002] Bearings used in current aerospace applications require high precision and accurate data. In existing bearing manufacturing processes, the bearing is typically clamped by a clamping mechanism during grinding, and then processed by a grinding tool. However, to prevent rotation, the existing clamping mechanism often holds a portion of the bearing in place. In practical applications, the high stability of this clamping mechanism means that after the ground portion is finished, the clamping mechanism needs to be opened, and the bearing manually adjusted to change its orientation. This adjustment is cumbersome, and because the bearing's precision is so high, if the bearing angle changes without notice, it's easy to miss which part was not processed. Summary of the Invention

[0003] The purpose is to address the shortcomings of existing technologies. Because the clamping mechanism offers high stability, after the bearing grinding is complete, the clamping mechanism needs to be opened, and the bearing manually adjusted by changing its orientation. This adjustment is cumbersome each time, and due to the high precision of the bearings, if the bearing angle changes without notice, it's easy to misidentify which parts were not machined. Therefore, this invention provides a precision bearing grinding device for aerospace applications.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a precision bearing grinding device for aerospace applications, comprising a bearing body and a clamping mechanism. The clamping mechanism includes a bracket, a baffle fixedly connected to the top of the bracket, a hydraulic rod fixedly mounted on one inner wall of the bracket, a telescopic rod fixedly connected to one end of the hydraulic rod, a connecting frame fixedly connected to one end of the telescopic rod, two clamping rods fixedly connected to one side of the connecting frame, a sliding hole opened at the bottom of the bracket, a sliding plate slidably connected to the inner wall of the sliding hole, and an arc-shaped clamping block fixedly connected to the top of the sliding plate. The top of the bracket is provided with an adjustment mechanism, which includes a support frame and a rotating tube. A rotating rod is rotatably connected to the inner top surface of the rotating tube. The bottom end of the rotating rod is fixedly connected to the inner bottom surface of the bracket. A torsion spring is provided on the outer surface of the rotating rod. One end of the torsion spring is fixedly connected to the inner bottom surface of the bracket, and the other end of the torsion spring is fixedly connected to the inner top surface of the rotating tube. A rotating ring is rotatably connected to the bottom end of the rotating tube. The bottom of the rotating ring is fixedly connected to the inner top surface of the bracket. Two rotating plates are fixedly connected to the outer surface of the rotating tube, and a rotating rod is rotatably connected between one side of the two rotating plates.

[0005] In a preferred embodiment, the outer surface of the bearing body is attached to the outer surface of the arc-shaped clamp and the outer surface of the clamp rod, and one side of the rotating rod is attached to the outer surface of the bearing body.

[0006] In a preferred embodiment, a servo motor is fixedly installed on the top of the support frame, and a first shaft is fixedly connected to the output end of the servo motor. A second shaft is rotatably connected to the top of one of the rotating plates. A first gear is fixedly sleeved on the outer surface of both the first shaft and the second shaft. A first chain is provided on the outer surface of the first gear, and the two first gears are connected by the first chain.

[0007] In a preferred embodiment, a third shaft is rotatably connected to the outer surface of one of the rotating plates. The bottom end of the third shaft is fixedly connected to the top end of the rotating rod. A second gear is fixedly sleeved on the outer surface of both the third shaft and the second shaft. A second chain is provided on the outer surface of the second gear. The two second gears are connected by the second chain for transmission.

[0008] In a preferred embodiment, a first fixing frame is fixedly connected to the inner bottom surface of the bracket, and a second fixing frame is fixedly connected to the inner bottom surface of the bracket.

[0009] In a preferred embodiment, the inner wall of the first fixing frame is fixedly connected to the outer surface of the hydraulic rod, and the inner wall of the second fixing frame is slidably connected to the outer surface of the hydraulic rod.

[0010] In a preferred embodiment, a spring is provided on the outer surface of the telescopic rod, one end of the spring is fixedly connected to one side of the connecting frame, and the other end of the spring is fixedly connected to one end of the hydraulic rod.

[0011] In a preferred embodiment, a limiting rod is fixedly connected to the inner bottom surface of the bracket, and a limiting hole adapted to the limiting rod is provided on the top of the arc-shaped clamping block. The inner wall of the limiting hole is slidably connected to the outer surface of the limiting rod.

[0012] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0013] 1. In this invention, a hydraulic rod, a telescopic rod, and a connecting frame drive a clamping rod to move towards the bearing body. Simultaneously, the bearing body is limited by an arc-shaped clamping block, thus clamping and fixing the bearing body. When the bearing body needs adjustment, the hydraulic rod drives the clamping rod away from the bearing body. Then, a servo motor, a first shaft, a second shaft, a first gear, a first chain, a third shaft, a second gear, and a second chain drive a rotating rod to rotate. Due to the action of a torsion spring, the rotating rod is tightly attached to the outer surface of the bearing body. The torsion spring provides a force to the rotating tube, and through a rotating plate, the rotating rod has a force that rotates towards the bearing body, thus ensuring that the rotating rod is tightly attached to the outer surface of the bearing body. When the servo motor drives the first shaft to rotate, the first gear, the first chain, the second shaft, the second gear, and the third shaft drive the rotating rod to rotate, causing the bearing body to rotate. At this point, the bearing body adjustment is complete.

[0014] 2. In this invention, the first fixing frame is fixed to the fixed end of the hydraulic rod, and the second fixing frame is fixed to the output end of the hydraulic rod. The cooperation between the first fixing frame and the bracket increases the structural stability of the hydraulic rod. At the same time, the second fixing frame limits the output end of the hydraulic rod, thereby increasing the stability of the hydraulic rod when it outputs. The spring provides a buffer force to the telescopic rod. One end of the spring is fixed to one side of the connecting frame, and the other end of the spring is fixed to the fixed end of the telescopic rod. This provides a certain buffer effect when the telescopic rod extends and retracts, preventing the bearing body from being suddenly clamped and damaged. The cooperation between the limiting rod and the sliding plate makes the structure of the arc-shaped clamp more stable and also facilitates the replacement of different arc-shaped clamp models so that the arc of the arc-shaped clamp can be matched with the bearing body.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1

[0027] like Figure 1-6As shown, the present invention provides a technical solution: a precision bearing grinding device for aerospace applications, comprising a bearing body 1 and a clamping mechanism 2. The clamping mechanism 2 includes a bracket 21, a baffle 3 fixedly connected to the top of the bracket 21, a hydraulic rod 22 fixedly installed on one inner wall of the bracket 21, a telescopic rod 25 fixedly connected to one end of the hydraulic rod 22, a connecting frame 27 fixedly connected to one end of the telescopic rod 25, two clamping rods 28 fixedly connected to one side of the connecting frame 27, a sliding hole 210 opened at the bottom of the bracket 21, a sliding plate 211 slidably connected to the inner wall of the sliding hole 210, and a fixed top of the sliding plate 211. An arc-shaped clamping block 212 is connected to the bracket 21. An adjustment mechanism 29 is provided on the top of the bracket 21. The adjustment mechanism 29 includes a support frame 291 and a rotating tube 292. A rotating rod 293 is rotatably connected to the inner top surface of the rotating tube 292. The bottom end of the rotating rod 293 is fixedly connected to the inner bottom surface of the bracket 21. A torsion spring 294 is provided on the outer surface of the rotating rod 293. One end of the torsion spring 294 is fixedly connected to the inner bottom surface of the bracket 21, and the other end of the torsion spring 294 is fixedly connected to the inner top surface of the rotating tube 292. A rotating ring 295 is rotatably connected to the bottom end of the rotating tube 292. The bottom of the rotating ring 295 is fixedly connected to the inner top surface of the bracket 21. The connection includes two rotating plates 296 fixedly connected to the outer surface of the rotating tube 292, and a rotating rod 297 rotatably connected between one side of the two rotating plates 296. The outer surface of the bearing body 1 is attached to the outer surface of the arc-shaped clamping block 212 and the outer surface of the clamping rod 28. One side of the rotating rod 297 is attached to the outer surface of the bearing body 1. A servo motor 298 is fixedly installed on the top of the support frame 291. A first shaft 299 is fixedly connected to the output end of the servo motor 298. A second shaft 2910 is rotatably connected to the top of one of the rotating plates 296. The outer surfaces of the first shaft 299 and the second shaft 2910 are both fixedly connected. A first gear 2911 is fixedly mounted, and a first chain 2912 is provided on the outer surface of the first gear 2911. The two first gears 2911 are connected by the first chain 2912. A third shaft 2913 is rotatably connected to the outer surface of one of the rotating plates 296. The bottom end of the third shaft 2913 is fixedly connected to the top end of the rotating rod 297. A second gear 2914 is fixedly mounted on the outer surface of both the third shaft 2913 and the second shaft 2910. A second chain 2915 is provided on the outer surface of the second gear 2914. The two second gears 2914 are connected by the second chain 2915.

[0028] In the above embodiments, the hydraulic rod 22, telescopic rod 25, and connecting frame 27 drive the clamping rod 28 to move towards the bearing body 1. Simultaneously, the bearing body 1 is limited by the arc-shaped clamping block 212, thus clamping and fixing the bearing body 1. When the bearing body 1 needs adjustment, the hydraulic rod 22 drives the clamping rod 28 away from the bearing body 1. Then, the servo motor 298, first shaft 299, second shaft 2910, first gear 2911, first chain 2912, third shaft 2913, second gear 2914, and second chain 2915 drive the rotating rod 297 to rotate. The rotating rod 297 is... Due to the action of the torsion spring 294, it will be tightly attached to the outer surface of the bearing body 1. The torsion spring 294 gives force to the rotating tube 292, and through the rotating plate 296, it makes the rotating rod 297 have a force to rotate towards the bearing body 1, so that the rotating rod 297 can be tightly attached to the outer surface of the bearing body 1. When the servo motor 298 drives the first shaft 299 to rotate, the first gear 2911, the first chain 2912, the second shaft 2910, the second gear 2914 and the third shaft 2913 drive the rotating rod 297 to rotate, so that the bearing body 1 rotates. At this time, the bearing body 1 completes the adjustment.

[0029] A first fixing frame 23 is fixedly connected to the inner bottom surface of the bracket 21, and a second fixing frame 24 is fixedly connected to the inner bottom surface of the bracket 21. The inner wall of the first fixing frame 23 is fixedly connected to the outer surface of the hydraulic rod 22, and the inner wall of the second fixing frame 24 is slidably connected to the outer surface of the hydraulic rod 22.

[0030] In the above embodiments, the first fixing frame 23 is fixed to the fixed end of the hydraulic rod 22, and the second fixing frame 24 is fixed to the output end of the hydraulic rod 22. Through the cooperation between the first fixing frame 23 and the bracket 21, the structural stability of the hydraulic rod 22 can be increased. At the same time, the second fixing frame 24 can limit the output end of the hydraulic rod 22, thereby increasing the stability of the hydraulic rod 22 when it outputs.

[0031] A spring 26 is provided on the outer surface of the telescopic rod 25. One end of the spring 26 is fixedly connected to one side of the connecting frame 27, and the other end of the spring 26 is fixedly connected to one end of the hydraulic rod 22.

[0032] Through the above embodiments, the spring 26 can provide a buffering force to the telescopic rod 25. One end of the spring 26 is fixed to one side of the connecting frame 27, and the other end of the spring 26 is fixed to the fixed end of the telescopic rod 25, so that the telescopic rod 25 has a certain buffering effect when it is telescopic, preventing the bearing body 1 from being suddenly clamped by force and damaged.

[0033] A limiting rod 213 is fixedly connected to the inner bottom surface of the bracket 21, and a limiting hole 214 adapted to the limiting rod 213 is opened on the top of the arc-shaped clamp 212. The inner wall of the limiting hole 214 is slidably connected to the outer surface of the limiting rod 213.

[0034] Through the above embodiments, the structure of the arc-shaped clamp 212 can be made more stable by the cooperation of the limiting rod 213 and the sliding plate 211. At the same time, it is convenient to replace the arc-shaped clamp 212 with different arc models so that the arc of the arc-shaped clamp 212 is not mismatched with the bearing body 1.

[0035] Working principle:

[0036] like Figure 1-6 As shown, an arc-shaped clamping block 212, adapted to the bearing body 1, is installed at the limiting rod 213. Simultaneously, the sliding plate 211 is pressed into the inner wall of the sliding hole 210. Then, the bearing body 1 is fitted onto the outer surface of the arc-shaped clamping block 212, with the inner wall of the bearing body 1 adhering to the outer surface of the arc-shaped clamping block 212. Next, the hydraulic rod 22 extends, causing the clamping rod 28 to move towards the bearing body 1. The clamping rod 28 and the arc-shaped clamping block 212 clamp the bearing body 1, allowing for processing of the bearing body 1. When the machining position of the bearing body 1 needs to be changed, the hydraulic rod 22 retracts, causing the clamping rod 28 to move away from the bearing body 1 by 5 millimeters. At this time, the bearing body 1 will be clamped by the rotating rod 297 and the arc-shaped clamping block 212. The servo motor 298 drives the rotating rod 297 to move, and the movement of the rotating rod 297 drives the bearing body 1 to move. At this time, the machining position of the bearing body 1 can be adjusted. Then, the hydraulic rod 22 drives the clamping rod 28 to clamp and fix the bearing body 1, and the machining can continue.

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 invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
