Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, and in particular to a multi-specification bearing inner and outer diameter synchronous grinding equipment. Background Technology

[0002] Bearings are important components in mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction generated during their movement, and ensure their rotational accuracy. In the bearing production process, in order to ensure the accuracy of the bearing, it is generally necessary to grind the inner and outer diameters of the bearing rings to make their surfaces smooth and flat, thus ensuring production quality. Therefore, grinding equipment is required.

[0003] Most existing grinding equipment uses two clamping methods, internal clamping and external clamping, to clamp bearing rings. In internal clamping, the outer ring of the bearing ring is unobstructed and can contact the grinding disc for outer ring grinding. In external clamping, the inner ring is unobstructed and can contact the surface of the grinding roller for inner ring grinding. This clamping method requires two grinding operations to be completed when grinding bearing rings. Although it can achieve the grinding process, it greatly reduces the grinding efficiency of bearing rings and there is room for improvement. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a synchronous grinding device for the inner and outer diameters of bearings of various specifications.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-specification bearing inner and outer diameter synchronous grinding equipment includes a processing table. Two support frames are fixedly connected to the upper surface of the processing table. Clamping components are fixedly connected to the opposite sides of the two support frames. A grinding component is provided on the upper surface of the processing table. The clamping component includes a servo motor. A strip plate is fixedly connected to the output end of the servo motor. Two sleeves are fixedly connected to the opposite sides of the two strip plates. A positioning plate is fixedly connected to the end of the sleeve away from the strip plate. An adjusting screw is threaded to the side of the positioning plate. A clamping frame is rotatably connected to the opposite ends of the two adjusting screws. A circular plate is slidably connected to the inner wall of the sleeve. A limit rod is fixedly connected to the side of the circular plate.

[0007] Preferably, the two sets of limiting rods are fixedly connected to the opposite sides of the two clamping frames, and the sides of the two positioning plates are provided with through holes that are compatible with the limiting rods.

[0008] Preferably, threaded rods are rotatably connected to the front, back, and upper and lower surfaces of the clamping frame, and four strip grooves are provided on the side of the clamping frame, with the four threaded rods rotatably connected to the inner walls of the four strip grooves respectively.

[0009] Preferably, each of the four strip grooves has a transmission block slidably connected to its inner wall. The four transmission blocks are threadedly connected to four threaded rods respectively. A clamping pin is fixedly connected to the side of the transmission block away from the inner wall of the strip groove. A rectangular hole is opened on the side of the clamping frame. A drive motor is fixedly connected to the inner wall of the rectangular hole. A grinding roller is inserted into the output end surface of the drive motor. The output end of the drive motor has a rectangular structure, and a slot adapted to the output end of the drive motor is opened on the side of the grinding roller. When the two clamping frames are close to each other, they can drive the two sets of clamping pins to clamp the left and right annular positions of the bearing ring, ensuring the stability of the bearing ring during the grinding process.

[0010] The clamping frame is equipped with a battery pack that powers the drive motor. Therefore, when the servo motor drives the entire clamping frame to rotate, it will not affect the normal operation of the drive motor. The grinding roller is mainly fitted onto the rectangular output end of the drive motor through a slot, so it can be easily removed from the output end of the drive motor. After the two clamping frames are brought close together, the right end of the grinding roller can overlap with the side of the other clamping frame, which restricts the position of the grinding roller during rotation, thereby ensuring the stability of the grinding roller during use.

[0011] Preferably, the grinding assembly includes a U-shaped frame, the inner wall of which is provided with a fixing groove. A positive and negative threaded rod is rotatably connected to the inner bottom wall of the fixing groove. Two sliders are slidably connected to the inner wall of the fixing groove. A mounting frame is fixedly connected to the front of each slider. The two sliders are threaded to the positive and negative threads on the surface of the positive and negative threaded rods, respectively. Rotating the positive and negative threaded rods can drive the two sliders to move closer to or further away from each other in the fixing groove.

[0012] Preferably, mounting plates are inserted into the opposite faces of the two mounting frames, and grinding plates are fixedly connected to the opposite faces of the two mounting plates. Four mounting bolts are threaded onto the opposite back faces of the two mounting frames. The mounting plates have four threaded grooves that match the mounting bolts. The two sliders can drive the two grinding plates to move closer or further apart through the mounting plates, thereby driving the two grinding plates to contact the outer surface of the bearing ring. This design is suitable for bearing rings of different sizes and specifications, offering high flexibility. The grinding plates can be quickly removed from the mounting frames through the cooperation of the mounting bolts and mounting plates, facilitating replacement when the grinding plates are severely worn.

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

[0014] 1. Through the coordinated setup of the clamping and grinding components, during use, the adjusting screw, clamping frame, and clamping pins can be used to clamp the two annular positions on both sides of the bearing ring. Furthermore, using two servo motors, the bearing ring can be rotated without contacting the inner and outer ring surfaces, allowing the outer ring to contact the grinding plate and the inner ring to contact the grinding roller, thereby completing the synchronous grinding of the inner and outer rings of the bearing ring and greatly improving the grinding efficiency of the bearing ring.

[0015] 2. By using the forward and reverse threaded rods, sliders, mounting frames, and drive motors, the distance between the two grinding plates can be changed by rotating the forward and reverse threaded rods, thus making it suitable for bearing rings of different diameters. Furthermore, the grinding rollers can be directly removed from the output end of the drive motor. During use, the two ends are restricted to maintain stability, allowing for replacement according to the inner diameter of bearing rings of different specifications. This improves the applicability of the grinding device and provides high flexibility. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, referring to Figure 1-5 A multi-specification bearing inner and outer diameter synchronous grinding equipment includes a processing table 1. Two support frames 2 are fixedly connected to the upper surface of the processing table 1. Clamping components 3 are fixedly connected to the opposite sides of the two support frames 2. A grinding component 4 is provided on the upper surface of the processing table 1. The clamping component 3 includes a servo motor 301. A strip plate 302 is fixedly connected to the output end of the servo motor 301. Two sleeves 303 are fixedly connected to the opposite sides of the two strip plates 302. A positioning plate 304 is fixedly connected to the end of the sleeve 303 away from the strip plate 302. An adjusting screw 305 is threadedly connected to the side of the positioning plate 304. A clamping frame 306 is rotatably connected to the opposite ends of the two adjusting screws 305. A circular plate 307 is slidably connected to the inner wall of the sleeve 303. A limit rod 308 is fixedly connected to the side of the circular plate 307.

[0024] Two sets of limiting rods 308 are fixedly connected to the opposite sides of the two clamping frames 306 respectively, and the sides of the two positioning plates 304 are provided with through holes that are compatible with the limiting rods 308. The front, back and upper and lower surfaces of the clamping frame 306 are rotatably connected with threaded rods 309. The sides of the clamping frame 306 are provided with four strip grooves. The four threaded rods 309 are rotatably connected to the inner walls of the four strip grooves respectively. The inner walls of the four strip grooves are slidably connected with transmission blocks 310. The four transmission blocks 310 are threadedly connected to the four threaded rods 309 respectively. The side of the transmission block 310 away from the inner wall of the strip groove is fixedly connected with a clamping pin 311.

[0025] By rotating the two adjusting screws 305, the two clamping frames 306 can be driven to move closer to each other. The two clamping frames 306 can drive the two sets of clamping pins 311 to move closer to each other. The two sets of clamping pins 311 can press against the left and right annular positions of the bearing ring. After the two servo motors 301 are started synchronously, the bearing ring can be driven to rotate without affecting the inner and outer diameter surfaces of the bearing ring.

[0026] In addition, when the two clamping frames 306 move closer or further apart, they are restricted by the circular plate 307 and the limiting rod 308, so the clamping frames 306 will not rotate or shift, and the stability is higher.

[0027] By rotating the threaded rod 309, the transmission block 310 can be moved in the strip groove, thereby changing the position of the four clamping pins 311, which facilitates the clamping operation of bearing rings of different diameters.

[0028] A rectangular hole is provided on the side of the clamping frame 306. A drive motor 312 is fixedly connected to the inner wall of the rectangular hole. A grinding roller 313 is inserted into the output end surface of the drive motor 312. The output end of the drive motor 312 has a rectangular structure, and a slot adapted to the output end of the drive motor 312 is provided on the side of the grinding roller 313.

[0029] When the two clamping frames 306 are close to each other, the grinding roller 313 can pass through the inner wall of the bearing ring, and its right end overlaps with the side of the other clamping frame 306. Since the grinding roller 313 is fitted onto the output end of the drive motor 312 through a slot, it can be easily removed and replaced. This makes it convenient to change the size of the grinding roller 313 that is compatible with the bearing ring when grinding bearing rings of different specifications, which is highly flexible.

[0030] In addition, the output end of the drive motor 312 can cooperate with the slot to drive the grinding roller 313 and the bearing ring to rotate in opposite directions. Since the left side of the grinding roller 313 is restricted by the output end of the drive motor 312, while the right side is pressed by the side of the clamping frame 306, there will be no separation or displacement, and the stability is high.

[0031] Example 2: The grinding assembly 4 includes a U-shaped frame 401. The inner wall of the U-shaped frame 401 is provided with a fixing groove. The inner bottom wall of the fixing groove is rotatably connected to a positive and negative threaded rod 402. The inner wall of the fixing groove is slidably connected to two sliders 403. The front of each slider 403 is fixedly connected to a mounting frame 404. The two sliders 403 are respectively threaded to the positive and negative threads on the surface of the positive and negative threaded rod 402. Mounting plates 405 are inserted into the opposite sides of the two mounting frames 404. Grinding plates 406 are fixedly connected to the opposite sides of the two mounting plates 405. Four mounting bolts 407 are threadedly connected to the opposite back sides of the two mounting frames 404. The mounting plates 405 are provided with four threaded grooves that are compatible with the mounting bolts 407.

[0032] By rotating the forward and reverse threaded screws 402, the two sliders 403 can be moved closer or further apart in the fixed groove. After the two sliders 403 move closer to each other, the two mounting frames 404 and mounting plate 405 can drive the two grinding plates 406 to move closer to each other, thereby driving the two grinding plates 406 to contact the surface of the clamped bearing ring, which facilitates the outer ring grinding of the bearing ring and can be applied to bearing rings of different sizes.

[0033] Working principle: First, the bearing ring to be ground synchronously in both inner and outer diameters is placed between two clamping frames 306. Then, the two adjusting screws 305 are rotated, causing the two clamping frames 306 to move closer together. Due to the restraint of the two sets of circular plates 307 and the limiting rods 308, the clamping frames 306 will not rotate or shift. This continues until the four clamping pins 311 on the opposite sides of the two clamping frames 306 press against the two sides of the bearing ring. At this point, the two sides of the bearing ring are clamped and locked by the four clamping pins 311. Simultaneously, the drive motor 312 drives the grinding roller 313 to insert into the inner wall of the bearing ring, with the right end of the grinding roller 313 overlapping the side of the other clamping frame 306. Then, rotating the positive and negative threaded screws 402 on the U-shaped frame 401 causes the two sliders 403 to move closer together. The two sliders 403 then move the mounting frame 404. When the two mounting frames 404 are brought closer together, the mounting plates 405, which are inserted face to face, can drive the two grinding plates 406 to move closer together, thus contacting the surface of the bearing ring. At this time, the two servo motors 301 are started simultaneously. The two servo motors 301 can drive the bearing ring to rotate through the clamping pins 311, thereby driving the bearing ring to contact the surface of the two grinding plates 406, realizing the outer grinding of the bearing ring. Meanwhile, the drive motor 312 drives the grinding roller 313 to rotate in the opposite direction to the bearing ring, which can perform grinding operation on the inner diameter of the bearing ring, realizing the synchronous grinding of the inner and outer diameters of the bearing ring. In addition, the threaded rod 309 can drive the transmission block 310 to slide in the strip groove, thereby changing the position of the clamping pins 311. The grinding roller 313 can be removed from the output end of the drive motor 312, and can be quickly replaced according to the inner diameter size of the bearing ring, which is convenient for clamping and grinding bearing rings of different specifications.

[0034] 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.
