Description

Technical Field

[0001] The invention relates to the technical field of roller ring processing, in particular to a bevel roller ring and a processing method of the bevel roller ring. Background Art

[0002] The Chinese patent application with application number 202310472308.5 discloses a method for processing a workpiece with an inclined surface, comprising the steps of: processing a first plane and a first inclined surface of a grinding jig, and forming a first angle with a first preset inclination angle between the first plane and the first inclined surface; rough-machining a second plane and a second inclined surface of the workpiece; fixing the rough-machining workpiece on the first inclined surface of the grinding jig, and using a machine tool to grind and finish the second plane and the second inclined surface of the workpiece, and forming a second angle with a second preset inclination angle between the second plane and the second inclined surface after grinding; the second preset inclination angle is equal to the first preset inclination angle ± a preset angle error value; using a machine tool to grind and finish the second plane of the workpiece until a second angle with a second preset inclination angle is formed between the second plane and the second inclined surface after grinding.

[0003] In the above technical scheme, after the second bevel grinding is completed, the workpiece and the grinding jig are loosened and turned over, so that the second bevel after grinding is against the first bevel of the grinding jig. However, in the above technical scheme, only a single-sided bevel on the workpiece can be processed by the first bevel of the grinding jig, and then a workpiece with only a single-sided bevel is produced, and the bevel processing of the symmetrical end faces on both sides of the workpiece cannot be performed. In the actual use of the roller ring, the roller ring with only a bevel on one side cannot use the adjacent spacer ring to limit the slippage of the single-piece roller ring, so that it cannot produce linkage with the spacer rings at both ends of the axial direction at the same time, resulting in the increase of the processing cost generated by processing the bevel. It is also impossible to achieve the limiting effect of the single-piece roller ring, and the use effect is not good. Summary of the invention

[0004] The purpose of the present invention is to provide a bevel roller ring which can machine bevels on both end faces of its own axial direction and a machining method of the bevel roller ring.

[0005] To achieve the above-mentioned purpose, the present invention discloses a bevel roller ring, including a roller ring body sleeved on a roller shaft, the roller ring body including a first roller ring for abutting against a shaft shoulder or a locking nut and a second roller ring located between two adjacent spacer rings, the axial end of the first roller ring facing away from the shaft shoulder or the locking nut is a bevel, and the two axial end surfaces of the second roller ring in contact with the spacer ring are both bevels, the bevel is a complete plane having a certain angle with the cross section of the roller ring body, and the spacer ring is obliquely matched between the two adjacent roller rings.

[0006] When the first roller ring and the second roller ring need to be installed, firstly sleeve the first roller ring on the outer circumferential surface of the roller shaft and make it butt against the shaft shoulder, then sleeve the second roller ring and the spacer ring on the outer circumferential surface of the roller shaft alternately in sequence, and then sleeve the first roller ring on the end of the outer circumferential surface of the roller shaft away from the shaft shoulder, after the axial inclined surfaces of the first roller ring, the spacer ring and the second roller ring are tightly butt against each other, assemble the locking nut on the roller shaft for axial limiting.

[0007] The present invention forms a whole with the roller ring and the spacer ring on the roller shaft by setting the contact end of the roller ring and the spacer ring matched with the roller ring as an inclined surface. When a single roller ring tends to slip, the interlocking sliding tendency guided by its inclination will be immediately resisted by the locking forces of the adjacent roller rings, the spacer rings and the locking nuts. Then, the locking forces of the adjacent roller rings, the spacer rings and the locking nuts are utilized to timely intervene in the slip of the single roller ring, thereby preventing the single roller ring from slipping. The present invention has the advantages of improving the stability and slip resistance of the roller ring.

[0008] Preferably, one axial end of the first roller ring close to the shaft shoulder or the locking nut is a plane.

[0009] Since the first roller rings located at the axial ends of the roller shaft and the second roller rings located between the first roller rings on both sides are integrally linked through the spacer rings, there is no need to perform bevel processing on the shaft shoulder and the contact surface between the locking nut and the roller ring while ensuring the stability and slip resistance of the roller rings, thereby reducing the processing difficulty and processing cost.

[0010] Preferably, the inclined surfaces at both axial ends of the second roller ring are symmetrically arranged with the cross section as the center plane.

[0011] The symmetrically arranged inclined surfaces gradually increase the thickness of the second roller ring from one radial side to the other side, thereby making the longitudinal cross-section of the second roller ring a single complete trapezoid. Compared with the roller ring inclined surfaces that are parallel to the inclined surfaces at both axial ends, the center of gravity of the second roller ring during operation is close to the thickest part of the roller ring in the axial direction, thereby generating centrifugal force when the composite roller rotates rapidly, thereby increasing the rolling force and further meeting the requirements of low-temperature rolling.

[0012] Preferably, the length difference h between the maximum axial length and the minimum axial length of the first roller ring is 1.5mm-2.3mm, and the length difference H between the maximum axial length and the minimum axial length of the second roller ring is 3mm-4.6mm.

[0013] By limiting the inclination angle of the inclined surfaces of the first roller ring and the second roller ring, it is prevented that the inclination angle of the inclined surface is too large, which will affect the supporting effect of the wall thickness of the edge of the annular groove used for rolling the roller ring, and even cause the roller ring to fall off and be damaged; or the inclination angle of the inclined surface is too small, which will reduce the overall locking effect of the roller ring and the spacer ring, thereby increasing the risk of the roller ring slipping.

[0014] A method for processing a bevel roller ring comprises the following steps: S1, taking two thin plates as first grinding pieces, and grinding the two first grinding pieces respectively according to different preset thicknesses; S2, taking two square plates as second grinding pieces for supporting the roller ring, and grinding the lower surfaces of the two second grinding pieces into smooth surfaces; S3, placing the second grinding piece on a horizontal plane, and padding the first grinding piece on the bottom of the second grinding piece, grinding the upper surface of the second grinding piece into a plane, and then processing two second grinding pieces with different inclined surface angles; S4, placing the magnetic base on a horizontal plane, keeping the upper end surface of the magnetic base horizontal, and placing the second wear member with a smaller inclined surface angle on the magnetic base; S5, placing one axial end of the roller ring in close contact with the upper inclined surface of the second grinding member and fixing them, and then grinding the other axial end of the roller ring into a plane, thus completing the inclined surface processing of one axial end of the roller ring; S6, flip the roller ring, and use the second grinding piece with a larger inclined surface angle to support the roller ring, tightly contact and fix the roller ring and the upper inclined surface of the second grinding piece, and then grind the other axial end of the roller ring into a plane, so as to complete the inclined surface processing of the axial ends of the roller ring.

[0015] Preferably, in step S1, according to the inclination angle of the inclined surface of the roller ring to be processed, the right-angle height required to achieve this inclination angle and twice the inclination angle is calculated respectively, and the right-angle height is the required thickness of the two first matching parts, thereby obtaining two first matching parts that can support the second matching parts to different heights.

[0016] Preferably, the step S3 specifically includes: S31, placing the second grinding piece on a horizontal plane, padding the first grinding piece on the bottom of the second grinding piece, recording the padding position of the first grinding piece, and grinding the upper surface of the second grinding piece into a plane; S32, using a three-coordinate inspection method to detect the inclination angle of the second wear part, and reprocessing the second wear part that does not meet the inclination angle requirement.

[0017] The inclination angle of the inclined surface of the second matching wear part is detected by the three-coordinate inspection method, so as to ensure the processing accuracy of the second matching wear part.

[0018] Preferably, in step S32, when the inclination angle of the inclined surface of the second matching wear part is too large, the entire upper surface of the first matching wear part is firstly smeared with a marker pen and ground, and after the marker pen mark on the entire surface is ground off, the first matching wear part is reassembled and processed according to the recorded position of the first matching wear part, and the second matching wear part is ground again until the inclination angle of the inclined surface of the second matching wear part meets the requirement; when the inclination angle of the inclined surface of the second matching wear part is too small, the distance that the first matching wear part needs to be pushed inward is calculated by a trigonometric function to raise the second matching wear part, the position of the first matching wear part is re-recorded, and the first matching wear part and the second matching wear part are ground again.

[0019] The thickness of the first grinding piece is ground according to the result of each measurement and the grinding amount is controlled by the mark of the marker pen, so as to reduce the thickness of the second grinding piece and ensure the processing accuracy of the second grinding piece.

[0020] Preferably, in step S5, the radial position of the roller ring is positioned and fixed by four V-shaped clamps arranged in an array in the circumferential direction of the roller ring, and the axial position of the roller ring is positioned and fixed by the magnetic force between the magnetic seat and the roller ring.

[0021] The roller ring on the second grinding member is limited and fixed by a magnetic seat and four V-shaped clamps arranged in an annular array, wherein the upper surface of the roller ring exceeds the upper limit position of the four V-shaped clamps, and the edge of the upper surface of the second grinding member is between the inner edge of the inner hole of the roller ring and the outer edge of the annular surface of the roller ring.

[0022] The V-shaped clamp block has the same structure as the power output end of the existing V-shaped clamping jaws.

[0023] Preferably, in step S6, the thinnest part of the roller ring in the axial direction is made to be opposite to the highest position of the second wear member, so that the second processed inclined surface of the roller ring is symmetrical with the first processed inclined surface.

[0024] The present invention can process the two axial end faces of the roller ring and produce a roller ring with symmetrical inclined surfaces at the two axial ends, so that the single-piece roller ring can utilize the locking force of adjacent roller rings, spacer rings and locking nuts to achieve overall linkage, thereby preventing the single-piece roller ring from slipping, and has the advantage of improving the stability and anti-slip ability of the roller ring.

[0029] Depend on Figure 2 As shown in the figure, the length difference h between the maximum axial length of the first roller ring 11 and the minimum axial length is 1.51 mm, so that the angle α between the inclined surface 14 of the first roller ring 11 and the minimum axial length is 1 is 89°40′, where the angle α 1 The tolerance is ±6', and the angle α between the inclined surface 14 of the first roller ring 11 and the maximum axial length is 2 Angle α 1 They are complementary angles.

[0030] Depend on Figure 3 As shown, the length difference H between the maximum axial length and the minimum axial length of the second roller ring 12 is 3mm-4.6mm, so that the angle α between the inclined surfaces 14 on both sides of the second roller ring 12 and the minimum axial length is 3 is 89°40′, where the angle α 3 The tolerance is ±6', and the angle α between the inclined surfaces 14 on both sides of the second roller ring 12 and the maximum axial length is 4 Angle α 3 They are complementary angles.

[0031] When the first roller ring 11, the second roller ring 12, the spacer ring and the locking nut are all mounted on the roller shaft, the inclination angles of the adjacent two end surfaces of the first roller ring 11, the second roller ring 12 and the spacer ring are the same.

[0032] A method for processing a bevel roller ring comprises the following steps: S1. Take two thin plates as the first grinding pieces, and calculate the right angle height required to achieve the inclination angle and twice the inclination angle according to the inclination angle of the roller ring to be processed. The right angle height is the required thickness of the two first grinding pieces, and grind the two first grinding pieces according to different preset thicknesses respectively; S2, taking two square plates as the second grinding pieces for supporting the roller ring, and grinding the lower surfaces of the two second grinding pieces into smooth surfaces; S31, placing the second grinding piece on a horizontal plane, padding the first grinding piece on the bottom of the second grinding piece, recording the padding position of the first grinding piece, and grinding the upper surface of the second grinding piece into a plane 13; S32, using a three-coordinate inspection method to detect the inclination angle of the inclined surface of the second wear part, and reprocessing the second wear part that does not meet the inclination angle requirement; S4.
