Description

Technical Field

[0001] This utility model relates to the field of bearing processing equipment, specifically a bearing inner ring raceway grinding device. Background Technology

[0002] Bearings are important components in mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. Bearings generally consist of four parts: an outer ring, an inner ring, rolling elements, and a cage. Raceways are usually provided on the inner wall of the outer ring and the outer wall of the inner ring to install the rolling elements and provide running space for them.

[0003] When grinding the raceway of a bearing, a polishing wheel is usually used to polish the inner wall of the raceway. However, the existing grinding equipment is inconvenient to use and adjust, cannot grind bearings of different sizes, and is difficult to replace, making it impossible to quickly complete the grinding of the bearing raceway. Utility Model Content

[0004] The purpose of this invention is to provide a bearing inner ring raceway grinding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A bearing inner ring raceway grinding apparatus includes a frame and further includes:

[0007] The rotating cylinder has a fixed plate and an adjusting plate on the outside of the frame, a collection box inside the frame, a vertical plate on the adjusting plate, a rotating cylinder on the vertical plate, multiple support cylinders on the outside of the rotating cylinder, a mounting rod on the support cylinder, a grinding wheel for grinding the inner ring of the bearing on one end of the mounting rod, and a support sleeve on the fixed plate.

[0008] The clamping plate has support frames on both sides of the support sleeve, multiple fixed columns on the support frames, clamping plates on the outside of the fixed columns, a threaded rod inside the support sleeve, and threaded grooves on the support frames that mate with the threaded rod. A support plate is mounted on the frame, and a support rod is slidably mounted on the support plate. A spring is sleeved on the outside of the support rod. A sleeve is mounted on the side wall of the rotating cylinder, and one end of the support rod passes through the inside of the sleeve.

[0009] The drive mechanism is connected to the support cylinder and can drive the support cylinder and the grinding wheel to rotate.

[0010] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0011] In one alternative: the driving mechanism includes a motor and a transmission belt, a fixed frame is provided on the vertical plate, the motor is provided on the fixed frame, a drive rod is provided at the rotating end of the motor, and a transmission belt is provided between the drive rod and the rotating cylinder.

[0012] In one alternative: the support cylinder has a threaded sleeve inside, the mounting rod has an external thread that mates with the threaded sleeve, the outer wall of the rotating cylinder has a rotating rod, and a gear set is provided between the rotating rod and the threaded sleeve.

[0013] In one alternative: the frame is provided with multiple positioning holes, and the adjusting plate is provided with a fixing pin, one end of which passes through the positioning hole.

[0014] In one alternative: a retaining plate is provided on the outside of the fixing plate, and a bolt is provided between the two retaining plates.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] The bearing inner ring raceway grinding device uses multiple sets of grinding wheels to grind the bearing inner ring. The drive mechanism drives the support cylinder and grinding wheels to rotate, and multiple grinding wheels move into the bearing to grind the bearing inner ring raceway. The spacing between the multiple sets of grinding wheels is adjustable, which facilitates the processing of bearings of different sizes. The adjustment plate slides left and right along the frame and drives the rotating cylinder to move horizontally, which can move grinding wheels with different roughness into the bearing, making the switching of grinding wheels more convenient and eliminating the need to repeatedly change grinding wheels, thus ensuring the normal use of bearing processing.

The mounting rod 15 can slide along the inner wall of the support cylinder 14 to facilitate the adjustment of the spacing of the multiple sets of grinding wheels 16, which is convenient for grinding the inner rings of bearings of different sizes. A support sleeve 9 is fixedly provided on the fixed plate 8.

[0025] The clamping plate 21 and the support sleeve 9 are slidably provided with support frames 10 on both sides. The support frames 10 are provided with multiple fixed columns 20, which are rubber columns to facilitate the compression and fixation of the bearing body 13. The clamping plate 21 is provided outside the fixed columns 20. The support sleeve 9 is rotatably provided with a threaded rod 11. The two ends of the threaded rod 11 are provided with external threads with opposite directions. The support frame 10 is provided with a threaded groove 12 that cooperates with the threaded rod 11. The threaded rod 11 rotates and drives the support frames 10 to move closer to each other, which can fix the bearing body 13. The frame 1 is fixedly provided with a support plate 7. The support plate 7 is slidably provided with a support rod 6. The support rod 6 is sleeved with a spring 22. The side wall of the rotating cylinder 4 is provided with a sleeve 401. One end of the support rod 6 passes into the sleeve 401 and the support rod 6 provides auxiliary support for the rotating cylinder 4.

[0026] The drive mechanism is connected to the support cylinder 14 and can drive the support cylinder 14 and the grinding wheel 16 to rotate.

[0027] The bearing inner ring raceway grinding device drives the support cylinder 14 and the grinding wheel 16 to rotate through the drive mechanism. Multiple grinding wheels 16 move into the bearing and grind the bearing inner ring raceway. The spacing between multiple sets of grinding wheels 16 is adjustable, which facilitates the processing of bearings of different sizes. The adjusting plate 2 slides left and right along the frame 1 and drives the rotating cylinder 4 to move horizontally, which can move grinding wheels 16 with different roughness into the bearing, making the switching of grinding wheels 16 more convenient. As an embodiment, the left, right and up and down positions of the various components shown in the figure are only one arrangement method. The specific positions are set according to specific needs.
