Description

[0002] A bearing washer is a component used to support a bearing. It is generally made of alloy or metal material and is installed between the outer ring of the bearing and the bearing seat. When the bearing is running, tiny gaps may appear between the bearing and the base.

[0018] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0019] The present invention provides Figure 1-9 A bearing gasket parallelism correction device shown in the figure comprises a lower frame 1 and an upper frame 5, wherein the upper frame 5 is arranged on the top of the lower frame 1 by bolts, and a plurality of lower squeezing rollers 7 are rotatably connected to the inner wall of the lower frame 1, and an upper squeezing roller 8 is arranged directly above each lower squeezing roller 7, and the upper squeezing roller 8 can be tightly pressed on the top of the lower squeezing roller 7, and the surfaces of the upper squeezing roller 8 and the lower squeezing roller 7 are covered with a layer of anti-slip rubber; A pressing plate 9 is provided inside the upper frame 5, and both ends of the upper squeezing roller 8 are rotatably connected to end plates 13, and the end plates 13 are fixedly arranged at the bottom of the pressing plate 9. An elastic pressing component 6 for driving the pressing plate 9 to press downward is provided at the top of the upper frame 5, and the elastic pressing component 6 provides downward squeezing force for the upper squeezing roller 8 and the pressing plate 9; A transmission assembly 2 is provided on one side of the lower frame 1 , and a rocker arm 3 is provided on the transmission assembly 2 . The rocker arm 3 drives all the lower squeezing rollers 7 to rotate synchronously through the transmission assembly 2 .

[0020] The elastic pressing component 6 drives the pressure plate 9 to press down, so that the upper squeezing roller 8 is tightly pressed against the top of the corresponding lower squeezing roller 7, and the rotating rocker arm 3 can drive all the lower squeezing rollers 7 to rotate synchronously through the transmission component 2. After the lower squeezing roller 7 rotates, under the action of friction, the corresponding upper squeezing roller 8 will also start to rotate. At this time, the deformed and warped bearing gasket is placed between the frontmost lower squeezing roller 7 and the upper squeezing roller 8. As the two rotate, the bearing gasket will be driven to move from front to back and be clamped between the lower squeezing roller 7 and the upper squeezing roller 8. As the bearing gasket moves backward, the bearing gasket will be squeezed one by one by each pair of mutually contacting lower squeezing rollers 7 and upper squeezing rollers 8, and finally led out from the rear side of the correction device, so that the deformed and warped bearing gasket can be flattened through multiple squeezing, so as to correct its parallelism, thereby increasing the qualified rate in the subsequent detection process.

[0021] Sufficient downward force is required to flatten the bearing spacers, such as Figure 4 , 5 As shown in , 7, a plurality of sleeves 12 are fixedly provided on the top of the upper frame 5, and a plurality of guide rods 11 are fixedly provided on the top of the pressure plate 9. The guide rods 11 correspond to the sleeves 12 one by one. The top of the guide rods 11 extends to the top of the upper frame 5 through the sleeves 12. The guide rods 11 can move vertically up and down along the sleeves 12. The elastic downward pressing assembly 6 includes a top frame 601, and the top of the guide rods 11 is fixedly connected to the top frame 601.

[0022] A threaded column 605 is fixedly provided at the top of the upper frame 5, and an adjusting sleeve 604 is provided at the top of the threaded column 605 through a threaded sleeve. The height of the adjusting sleeve 604 can be adjusted by rotating it. A mounting plate 603 is rotatably connected to the top of the adjusting sleeve 604, and a spring 602 is fixedly provided at the top of the mounting plate 603. The top of the spring 602 is fixedly connected to the top frame 601.

[0023] The spring 602 located above the upper frame 5 is always in a stretched state. The stretched spring 602 pulls the top frame 601 downward by its own elastic force. The top frame 601 therefore pushes the pressure plate 9 vertically downward through the guide rod 11. The pressure plate 9 therefore drives the upper extrusion roller 8 downward, so that the upper extrusion roller 8 squeezes the lower extrusion roller 7 downward, and then squeezes the bearing gasket downward during the correction work. When performing the correction work, the adjusting sleeve 604 can be rotated. Under the action of the thread, the rotation of the adjusting sleeve 604 makes it move up and down along the threaded column 605. The mounting plate 603 moves synchronously with the adjusting sleeve 604 and drives the spring 602 to control its stretched length, and then adjust its elastic force, thereby controlling the extrusion force during the correction process.

[0024] In order to make all the lower squeezing rollers 7 move synchronously, as Figure 1 , 6As shown in , 8, the transmission assembly 2 includes a transmission box 201 fixed on one side of the lower frame 1, a cover plate 202 is provided on one side of the transmission box 201 by bolts, a driving shaft 207 is rotatably connected to the cover plate 202, the rocker arm 3 is fixed on one end of the driving shaft 207, and the other end of the driving shaft 207 extends to the interior of the transmission box 201 and is fixedly provided with an active bevel gear 208.

[0025] A transmission shaft 203 is rotatably connected to the inner wall of the transmission box 201, and a plurality of transmission bevel gears 204 are fixedly disposed at the outer end of the transmission shaft 203. The active bevel gear 208 is meshed with one of the transmission bevel gears 204, so that the rotation of the active bevel gear 208 can drive the transmission bevel gear 204; A plurality of extension shafts 205 are provided inside the transmission box 201, and a driven bevel gear 206 is fixedly provided at one end of the extension shaft 205. The driven bevel gear 206 corresponds one-to-one with the transmission bevel gear 204 and meshes with the corresponding transmission bevel gear 204. The extension shaft 205 corresponds one-to-one with the lower extrusion roller 7. The other end of the extension shaft 205 extends to the inside of the lower frame 1 and is fixedly connected to the corresponding lower extrusion roller 7. The extension shaft 205 is rotatably connected to the transmission box 201 and the lower frame 1.

[0026] To drive the lower extrusion roller 7 to rotate and correct the bearing gasket, it is first necessary to manually drive the rocker arm 3 to rotate. After the rocker arm 3 rotates, it drives the drive shaft 207 and the active bevel gear 208 fixed at one end of the drive shaft 207 to rotate. The active bevel gear 208 is engaged with one of the transmission bevel gears 204, thereby driving the transmission bevel gear 204 to rotate, which makes the transmission shaft 203 and all the transmission bevel gears 204 at its outer end start to rotate. After the transmission bevel gear 204 rotates, it drives the driven bevel gear 206 engaged with it to rotate. The driven bevel gear 206 is connected to the lower extrusion roller 7. Rotating the rocker arm 3 can drive all the lower extrusion rollers 7 to rotate synchronously.

[0027] During the correction process, in order to avoid lateral displacement of the bearing spacer, such as Figure 6 As shown, both ends of the lower extrusion roller 7 are provided with annular side plates, the diameter of the annular side plates is larger than the diameter of the lower extrusion roller 7, the contact portion between the lower extrusion roller 7 and the upper extrusion roller 8 is located between the two annular side plates, and two detachable support plates 4 are provided on the inner wall of the lower frame 1, the top end of the support plate 4 is flush with the top end of the lower extrusion roller 7, and the lower extrusion roller 7 is located between the two support plates 4.

[0028] Before correction, the bearing gasket is placed on the top of the front support plate 4, and the bearing gasket is pushed along the top of the support plate 4 to move toward the lower frame 1. When the bearing gasket contacts the lower extrusion roller 7, it can be squeezed as the lower extrusion roller 7 rotates. After extrusion, the corrected gasket finally reaches the top of the rear support plate 4 and moves backward under the drive of the lower extrusion roller 7. During the correction process, since the diameter of the annular side plate is larger than the diameter of the lower extrusion roller 7, it can prevent the bearing gasket from lateral displacement and affecting the correction.

[0029] Only the bearing gasket with qualified parallelism after correction can pass through the limit assembly 10 smoothly. Figure 2 , 3 As shown in , 4 and 9, a limiting assembly 10 is provided on the top of the rear support plate 4, and the limiting assembly 10 includes a fixed shaft 1002 rotatably connected to the inner wall of the upper frame 5, a baffle 1001 is fixedly provided on the outer end of the fixed shaft 1002, a positioning cylinder 1003 is sleeved on one end of the fixed shaft 1002, and the positioning cylinder 1003 is fixed on the inner wall of the upper frame 5, and a fastening bolt is threadedly provided on the outer end of the positioning cylinder 1003, and the fixed shaft 1002 can be fixed after the fastening bolt is tightened.

[0030] The other end of the fixed shaft 1002 extends to the outside of the upper frame 5 and is fixedly provided with a handle 1004 , on which an indicating protrusion is fixedly provided, and a scale ring 1005 fixed to the upper frame 5 is provided on the outer side of the handle 1004 .

[0031] After being squeezed and corrected, the bearing gasket moves backward under the drive of the lower squeezing roller 7 and reaches the top of the rear support plate 4. During the process of moving backward along the rear support plate 4, the bearing gasket passes through the limit assembly 10. At this time, the baffle 1001 is in the tilting device. There is a gap between the rear end of the baffle 1001 and the top of the rear support plate 4. The height of the gap is slightly greater than the thickness of a normal bearing gasket. Therefore, if the bearing gasket has been fully corrected, it can smoothly pass through the gap and continue to move backward when passing through the baffle 1001 and finally separate from the lower squeezing roller 7 on the rear side to complete the correction. If the bearing gasket is not fully corrected, it means that the bearing gasket still has a warped deformation, and the bearing gasket cannot pass through the gap. The bearing gasket blocked by the baffle 1001 cannot continue to move backward. At this time, the rocker arm 3 can be rotated in the reverse direction, so that the lower squeezing roller 7 and the upper squeezing roller 8 are reversed, driving the originally backward-moving bearing gasket to move forward to the inside of the lower frame 1, and the squeezing correction work is performed again until the bearing gasket can smoothly pass through the gap, so as to ensure that the corrected bearing gasket can be qualified, so that the effect of the correction device is better; By rotating the handle 1004, the fixed shaft 1002 can be driven to rotate, and the inclination angle of the baffle 1001 can be adjusted according to the scale on the scale ring 1005. Different inclination angles will result in different heights of the gap, so that it can be suitable for bearing gaskets of different thicknesses.

[0032] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
