DETAILED DESCRIPTION

[0022] In order to make those skilled in the art better understand the technical solutions of the present application, the present application will be further described in detail with reference to the drawings.

[0023] like Figures 1-5 As shown, a bearing roller grinding device includes a lower grinding disc 3 with a receiving groove 31, and a left flap 35 and a right flap 33 that are hinged to each other and disposed opposite to each other in the receiving groove 31, and an angle-adjustable feed channel is formed between two adjacent surfaces of the left flap 35 and the right flap 33.

[0024] Multiple feed wheels 4 are rotatably arranged on adjacent surfaces, and multiple grinding teeth 45 are arranged in a circumferential array on them. The number and roughness of the grinding teeth 45 on the feed wheels 4 increase along the feed direction.

[0025] Specifically, both the left flap 35 and the right flap 33 are equipped with drive motors for driving the feed rollers 4, and the multiple feed rollers 4 are kept in synchronous motion through a transmission belt 41. It also includes an operating table 1, with a lower grinding disc 3 mounted on the operating table 1. An upper grinding disc 2 that moves vertically is also mounted on the operating table 1. Sliding rods 34 are slidably mounted on both sides of the inner wall of the receiving groove 31, and the left flap 35 and the right flap 33 are rotatably mounted on the sliding rods 34.

[0026] Furthermore, the angle between the left flap 35 and the right flap 33 is adjusted according to the specifications of the roller being processed, thus making the angle of the feed channel adjustable. Only the distance between the two slide rods 34 needs to be adjusted, which is suitable for rollers of different specifications. Then, the left flap 35 and the right flap 33 are made tangent to the arc surface of the roller, at which point the arc surface of the feed wheel 4 abuts against the side of the roller, ensuring that the apex of the roller is higher than the lower grinding disc 3. The upper grinding disc 2 and the drive motor are started, causing multiple feed wheels 4 to rotate simultaneously and drive the rollers to slide. The rollers move radially along the lower grinding disc 3, while the rotation of the upper grinding disc 2 causes multiple rollers to rotate and grind simultaneously. At this time, the rollers rotate relative to the grinding teeth 45, and the rotation plane of the rollers is perpendicular to the rotation plane of the grinding teeth 45. The grinding teeth 45 have the functions of limiting the rollers and grinding the side of the rollers. Since the number and roughness of the grinding teeth 45 increase along the feed direction, the grinding of the rollers by the grinding teeth 45 transitions from coarse grinding to fine grinding, further improving the grinding efficiency of the rollers.

[0027] In the above technology, the angle between the left flip plate 35 and the right flip plate 33 is adjusted according to the specifications of the roller being processed, thereby making the angle of the feed channel adjustable and suitable for rollers of different specifications. Furthermore, the grinding teeth 45 simultaneously function as roller positioning and grinding the roller's side surface, allowing the grinding process to transition from coarse grinding to fine grinding, further improving the roller's grinding efficiency.

[0028] As a further embodiment of this utility model, the feed wheel 4 includes abutments arranged in a circumferential array and slidably arranged in a radial direction, with grinding teeth 45 located on the arc surface of the abutments.

[0029] Specifically, it also includes a liquid storage chamber 42 disposed on the feed roller 4 and used to support the abutment block. It also includes a liquid inlet chamber 44 disposed on the feed roller 4, into which water is injected to fill the liquid storage chamber 42. The filled liquid storage chamber 42 supports the abutment block so that the abutment block abuts against the side of the roller. The liquid storage chamber 42 absorbs the vibration generated by the roller during grinding on the upper grinding disc 2, which is more conducive to the clamping of the roller by the feed roller 4. Furthermore, the water filling the liquid storage chamber 42 can cool the side of the roller, preventing localized high temperatures during the grinding process.

[0030] As a further embodiment of this utility model, a rubber valve 43 in a bulging state is provided on the liquid storage cavity 42, and the rubber valve 43 is used to maintain a predetermined distance between two adjacent abutments, and the ratio of the predetermined distance to the width of the abutment is less than 1:4.

[0031] Specifically, the rubber valve 43 is as follows Figure 5 The device is bulging as shown, and the rubber valve 43 has an opening pointing towards the gap between the blocks. Grinding fluid is injected into the reservoir 42, filling it completely. The grinding fluid then enters the gap between the blocks through the rubber valve 43. However, because the gap between two adjacent blocks is a long and narrow rectangle with a width-to-length ratio of less than 1:4, the grinding fluid remains stationary within the gap due to the shear force against the block sidewall and its own tension, preventing it from flowing out directly.

[0032] Until the side of the roller abuts against the grinding teeth 45, the roller squeezes the abutment block, causing the liquid in the liquid storage chamber 42 to be squeezed out. The gushing grinding fluid will enter the gap of the abutment block along the rubber flap 43, and drive the grinding fluid that was originally stationary in the gap to gush out to the side of the roller. It can be applied during the rotation of the roller. Compared with the conventional method of directly spraying grinding fluid, it can save grinding fluid and reduce waste.

[0033] As another embodiment of this utility model, it also includes a liquid collection tank 32 disposed in the receiving tank 31.

[0034] Specifically, the left flap 35 and the right flap 33 are provided with guide grooves 36 corresponding to the feed roller 4, and the guide grooves 36 point towards the collection tank 32. The feed roller 4 applies grinding fluid to the side of the roller. When there is too much grinding fluid, the excess grinding fluid will drip from the feed roller 4 into the guide grooves 36 and slide down along the guide grooves 36 into the collection tank 32. The guide grooves 36 are respectively opened on the adjacent surfaces of the left flap 35 and the right flap 33, forming a V-shape, which can guide the grinding fluid into the collection tank 32.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, 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.
