Description

Technical Field

[0001] The utility model relates to the field of bearing processing devices, and particularly relates to a bearing positioning device for bearing polishing. Background Technique

[0002] A bearing is a component that supports a shaft, used to guide the rotational movement of the shaft, and bear the load transmitted from the shaft to the machine frame. It is also known as the "joint of a machine". Its main function is to support the rotating body of the machine, reduce the friction coefficient during its movement, and ensure its rotational accuracy. A bearing usually consists of an inner ring, an outer ring, rolling elements, and a cage.

[0003] In order to improve the surface quality of bearings, reduce the friction coefficient, and extend the service life, bearings need to be polished during the processing process, so a polishing device is required. However, most current polishing devices do not have a positioning mechanism, and bearings may shake and displace during the polishing process, thereby affecting the polishing effect. Therefore, this application proposes a bearing positioning device for bearing polishing to meet the requirements. Content of the Utility Model

[0004] Technical problems to be solved: Shaking and displacement during the bearing polishing process will affect the polishing effect.

[0005] Aiming at the deficiencies of the prior art, the utility model provides a bearing positioning device for bearing polishing, which solves the problems mentioned in the background technique.

[0006] Technical Solution:

[0007] To achieve the above objectives, the utility model is realized through the following technical solutions:

[0008] A bearing positioning device for bearing polishing includes a base. One side of the top of the base is fixedly connected with a first mounting seat. The outer surface of the first mounting seat is provided with a first motor. The driving shaft of the first motor is fixedly connected with a clamping assembly. The other side of the top of the base is movably connected with a second mounting seat. The outer surface of the second mounting seat is provided with a second motor. The driving shaft of the second motor is provided with a polishing block. A moving groove is opened at the position below the second mounting seat on the top of the base. A moving block movably connected to the bottom of the second mounting seat is slidably connected in the moving groove. A screw rod passing through and threadedly connected to the moving block is rotatably connected in the moving groove. A third motor with a driving shaft fixedly connected to the screw rod is mounted on one side of the base. An adjusting assembly is provided at the connection between the second mounting seat and the moving block.

[0009] In a possible implementation, the clamping assembly includes a mounting plate, positioning rods, adjustment slots, and adjustment blocks. The mounting plate is fixedly connected to the drive shaft of the first motor. There are four groups of positioning rods which are rotatably connected to each other. The adjustment slots are formed on one side surface of the mounting plate. The adjustment blocks are slidably connected to the adjustment slots, and the positioning rods are rotatably connected to the adjustment blocks.

[0010] In a possible implementation, the clamping assembly further includes connecting blocks, fixing holes, fixing blocks, and fixing rods. The connecting blocks are fixedly connected to one side of a group of adjustment blocks and are slidably connected to the adjustment slots. There are several groups of fixing holes which are formed on both sides of the adjustment slots. The fixing blocks are movably connected to the mounting plate and are located on one side of the connecting blocks. The fixing rods are fixedly connected to the fixing blocks and are adapted to the sizes of the fixing holes.

[0011] In a possible implementation, the clamping assembly further includes a first chute, a through slot, a connecting rod, a first slider, and a first spring. The first chute is formed inside the connecting block. The through slot is formed on one side surface of the connecting block close to the fixing block and is communicated with the first chute. One end of the connecting rod is fixedly connected to the fixing block and extends through the through slot into the first chute. The first slider is fixedly connected to the other end of the connecting rod and is slidably connected to the first chute. The first spring is sleeved on the outer periphery of the connecting rod and its two ends are respectively fixedly connected to one side of the first slider and one side inner wall of the first chute.

[0012] In a possible implementation, the adjustment assembly includes a vertical slot, a vertical rod, insertion holes, a connecting slot, and an insertion rod. The vertical slot is formed at the bottom of the second mounting seat. The vertical rod is fixedly connected to the top of the moving block and is slidably connected to the vertical slot. There are several groups of insertion holes which penetrate the vertical rod. The connecting slot penetrates one side inner wall of the vertical slot. The insertion rod is movably connected to the connecting slot and is adapted to the sizes of the insertion holes.

[0013] In a possible implementation, the adjustment assembly further includes a second chute, a second slider, a second spring, and a pulling block. The second chute is formed on the inner wall of the connecting slot. The second slider is fixedly connected to the outer periphery of the insertion rod and is slidably connected to the second chute. The second spring is sleeved on the outer periphery of the insertion rod and its two ends are respectively fixedly connected to one side of the second slider and one side inner wall of the second chute. The pulling block is fixedly connected to the outer end of the insertion rod.

[0014] Beneficial effects:

[0015] First, by providing a clamping component, place the bearing to be polished in the middle of the positioning rods. Then, pull the fixed block outward, which drives the first slider to slide outward along the first chute through the connecting rod and compresses the first spring. When the fixed rod moves outward with the fixed block and moves out of the fixing hole, slide the adjusting block along the adjusting groove to drive the positioning rods to move synchronously. When all the positioning rods are in contact with the outer surface of the bearing, release the fixed block. The first spring rebounds and drives the fixed block to move inward through the first slider and the connecting rod. When the fixed rod moves inward with the fixed block and inserts into the fixing hole at the current position, the adjusting block can be fixed at the current position, thereby fixing the positioning rods at the current angle, and further clamping and fixing the bearing at the current position. This design enables the device to clamp and position bearings of different sizes through the positioning rods, effectively preventing the bearing from shaking and affecting the polishing work.

[0016] Second, by providing an adjusting component, pull the pulling block outward to drive the inserting rod to move outward and compress the second spring through the second slider. When the inserting rod moves out of the inserting hole, move the second mounting seat upward or downward to make the vertical rod slide up and down in the vertical chute. When the height of the polishing block is adapted to the bearing of the new size, release the pulling block. The second spring rebounds and drives the inserting rod to move inward through the second slider. When the inserting rod inserts into the inserting hole at the current height, the second mounting seat can be fixed at the current height. This design enables the device to polish bearings of different sizes by adjusting the height of the polishing block, with a wider range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] By providing a bearing positioning device for bearing polishing in an embodiment of the present application, the problems in the prior art are solved.

[0026] The technical solutions in the embodiments of the present application for solving the above problems are generally as follows:

[0027] The specific structure of this embodiment is as Figures 1 to 5 shown. A bearing positioning device for bearing polishing includes a base 1. One side of the top of the base 1 is fixedly connected with a first mounting seat 2. The outer surface of the first mounting seat 2 is provided with a first motor 3. The driving shaft of the first motor 3 is fixedly connected with a clamping assembly 4. The other side of the top of the base 1 is movably connected with a second mounting seat 5. The outer surface of the second mounting seat 5 is provided with a second motor 6. The driving shaft of the second motor 6 is provided with a polishing block 7. A moving groove 8 is opened at the position below the second mounting seat 5 on the top of the base 1. A moving block 9 movably connected to the bottom of the second mounting seat 5 is slidably connected in the moving groove 8. A screw 10 passing through and threadedly connected to the moving block 9 is rotatably connected in the moving groove 8. A third motor 11 with a driving shaft fixedly connected to the screw 10 is installed on one side of the base 1. An adjusting assembly 12 is provided at the connection between the second mounting seat 5 and the moving block 9.

[0028] In some examples, the clamping assembly 4 includes a mounting plate 41, a positioning rod 42, an adjusting groove 43 and an adjusting block 44. The mounting plate 41 is fixedly connected to the driving shaft of the first motor 3. Four groups of positioning rods 42 are provided and are rotatably connected to each other. The adjusting groove 43 is opened on one side surface of the mounting plate 41. The adjusting block 44 is slidably connected in the adjusting groove 43. The positioning rod 42 is rotatably connected to the adjusting block 44. By sliding the adjusting block 44 along the adjusting groove 43, the included angle of the positioning rods 42 can be adjusted, so that it can clamp and position bearings of different sizes.

[0029] In some examples, the clamping assembly 4 further includes a connecting block 45, fixing holes 46, a fixing block 47, and a fixing rod 48. The connecting block 45 is fixedly connected to one side of a set of adjusting blocks 44 and slidably connected to the adjusting groove 43. A number of groups of fixing holes 46 are provided and opened on both sides of the adjusting groove 43. The fixing block 47 is movably connected to the mounting plate 41 and is located on one side of the connecting block 45. The fixing rod 48 is fixedly connected to the fixing block 47 and is adapted to the size of the fixing hole 46. Removing the fixing rod 48 from the fixing hole 46 can adjust the angle of the positioning rod 42, and inserting the fixing rod 48 into the fixing hole 46 can fix the positioning rod 42 at the current position.

[0030] In some examples, the clamping assembly 4 further includes a first chute 49, a through groove 410, a connecting rod 411, a first slider 412, and a first spring 413. The first chute 49 is opened inside the connecting block 45. The through groove 410 is opened on the surface of the connecting block 45 close to the fixing block 47 and is communicated with the first chute 49. One end of the connecting rod 411 is fixedly connected to the fixing block 47 and passes through the through groove 410 and extends into the first chute 49. The first slider 412 is fixedly connected to the other end of the connecting rod 411 and is slidably connected to the first chute 49. The first spring 413 is sleeved on the outer periphery of the connecting rod 411 and its two ends are respectively fixedly connected to one side of the first slider 412 and one side inner wall of the first chute 49. Pulling the fixing block 47 outward can drive the first slider 412 to slide outward along the first chute 49 through the connecting rod 411 and compress the first spring 413. Releasing the fixing block 47, the first spring 413 rebounds and can drive the fixing block 47 to move inward through the first slider 412 and the connecting rod 411.

[0031] In some examples, the adjusting assembly 12 includes a vertical groove 121, a vertical rod 122, insertion holes 123, a connecting groove 124, and an insertion rod 125. The vertical groove 121 is opened at the bottom of the second mounting seat 5. The vertical rod 122 is fixedly connected to the top of the moving block 9 and is slidably connected to the vertical groove 121. A number of groups of insertion holes 123 are provided and penetrate through the vertical rod 122. The connecting groove 124 penetrates through one side inner wall of the vertical groove 121. The insertion rod 125 is movably connected to the connecting groove 124 and is adapted to the size of the insertion hole 123. Removing the insertion rod 125 from the insertion hole 123 can adjust the height of the second mounting seat 5, and inserting the insertion rod 125 into the insertion hole 123 can fix the second mounting seat 5 at the current height.

[0032] In some examples, the adjusting component 12 further includes a second sliding groove 126, a second sliding block 127, a second spring 128, and a pulling block 129. The second sliding groove 126 is formed on the inner wall of the connecting groove 124. The second sliding block 127 is fixedly connected to the outer periphery of the inserting rod 125 and is slidably connected to the second sliding groove 126. The second spring 128 is sleeved on the outer periphery of the inserting rod 125, and its two ends are respectively fixedly connected to one side of the second sliding block 127 and one side inner wall of the second sliding groove 126. The pulling block 129 is fixedly connected to the outer end of the inserting rod 125. Pulling the pulling block 129 outward can drive the inserting rod 125 to move outward and compress the second spring 128 through the second sliding block 127. Releasing the pulling block 129, the second spring 128 rebounds and can drive the inserting rod 125 to move inward through the second sliding block 127.

[0033] In a specific application scenario, first place the bearing to be polished in the middle of the positioning rod 42. Then, pull the fixing block 47 outward so that it drives the first sliding block 412 to slide outward along the first sliding groove 49 through the connecting rod 411 and compress the first spring 413. When the fixing rod 48 moves outward with the fixing block 47 and moves out of the fixing hole 46, slide the adjusting block 44 along the adjusting groove 43 to drive the positioning rod 42 to move synchronously. When all the positioning rods 42 are in contact with the outer surface of the bearing, release the fixing block 47. The first spring 413 rebounds and drives the fixing block 47 to move inward through the first sliding block 412 and the connecting rod 411. When the fixing rod 48 moves inward with the fixing block 47 and inserts into the fixing hole 46 at the current position, the adjusting block 44 can be fixed at the current position, thereby fixing the positioning rod 42 at the current angle, and further clamping and fixing the bearing at the current position. Then, start the third motor 11 to drive the screw rod 10 to rotate. Since the screw rod 10 is threadedly connected to the moving block 9 and the moving block 9 is slidably connected to the moving groove 8, the moving block 9 will slide along the moving groove 8 as the screw rod 10 rotates, so as to adjust the position of the second mounting seat 5. When the polishing block 7 moves synchronously with the second mounting seat 5 and is in close fit with the inner surface of the bearing, start the first motor 3 and the second motor 6 to drive the mounting plate 41 and the polishing block 7 to rotate respectively to start the polishing work. When polishing bearings of different sizes, pull the pulling block 129 outward to drive the inserting rod 125 to move outward and compress the second spring 128 through the second sliding block 127. When the inserting rod 125 moves out of the inserting hole 123, move the second mounting seat 5 upward or downward to make the vertical rod 122 slide up and down in the vertical groove 121. When the height of the polishing block 7 is adapted to the new size bearing, release the pulling block 129. The second spring 128 rebounds and drives the inserting rod 125 to move inward through the second sliding block 127. When the inserting rod 125 inserts into the inserting hole 123 at the current height, the second mounting seat 5 can be fixed at the current height. At this time, the inner wall of the new size bearing can be polished.

[0034] By adopting the above technical solution: not only can the bearing of different sizes be clamped and positioned by the positioning rod, effectively avoiding the influence of the bearing shaking on the polishing work during the polishing process, but also the bearing of different sizes can be polished by adjusting the height of the polishing block, with a wider application range.

[0035] Finally, it should be noted that: Obviously, the above embodiments are merely examples given for clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom still fall within the protection scope of the present invention.
