Description

Technical Field

[0001] The present invention relates to the technical field of tool grinding, and particularly relates to a diamond roller multi-angle grinding device. Background Art

[0002] For the dressing / grinding process of diamond rollers, in essence, it is carried out in cooperation with a dressing tool of corresponding specifications. Specifically, the diamond roller rotates at a constant speed, and the dressing tool supplies the stroke according to a preset program. Reference can be made to the relevant content in the publication number CN103495933A.

[0003] It should be noted that during the dressing process, angle switching needs to be carried out according to the outer contour of the diamond roller. The key lies in the rolling resistance and lateral vibration force generated by the lateral thrust of the dressing tool. The rolling resistance affects the grinding degree between the tool and the roller, while the lateral vibration force mainly acts on the dressing tool. Inaccurate lateral unidirectional vibration will affect the dressing effect, resulting in abnormal wear of the diamond roller. Especially for the grinding process in multiple angles, affected by the rolling resistance, the unidirectional vibration force is "dispersed", further affecting the stability of the dressing tool and exacerbating the abnormal wear degree of the diamond roller.

[0004] For this, the present application proposes a solution. Summary of the Invention

The rolling resistance and lateral vibration force generated during the grinding process of the diamond roller are both key parameters affecting the grinding quality. Especially during the multi-angle grinding process, the two affect each other. The key lies in that the unidirectional vibration force is "dispersed", further affecting the stability of the dressing tool and exacerbating the abnormal wear degree of the diamond roller.

[0014] The present invention has the following beneficial effects:

[0015] 1. The grinding process of the diamond roller is based on the grinding process of the grinding head gradually approaching the diamond roller rotating at a uniform speed. The principle of the turning machine tooling can be referred to to complete the grinding process of the outer edge of the diamond roller. Its essence is based on the linear sliding action of the sliding seat and the angular deflection of the adjustment table.

Specific implementation mode

[0027] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.

[0028] Embodiment 1: The rolling resistance and lateral vibration force generated during the grinding of the diamond roller are both key parameters affecting the grinding quality. Especially during multi-angle grinding, the two affect each other. The key lies in that the unidirectional vibration force is "dispersed", which further affects the stability of the dressing tool and exacerbates the abnormal wear degree of the diamond roller. Therefore, the following technical solutions are proposed:

[0029] Refer to Figures 1 to 8 , a multi-angle grinding device for a diamond roller in this embodiment includes a motor base 1 and a roller body 2 to be processed. An installation table 6 is installed at a position on one side of the motor base 1 corresponding to the roller body 2 to be processed. A sliding seat 5, a cooperating rotating plate 9, a driving motor 10 and an adjustment table 3 are arranged on the installation table 6. A grinding head corresponding to the roller body 2 to be processed is arranged on the adjustment table 3;

[0030] The adjustment table 3 is rotatably connected to the sliding seat 5 through the driving motor 10 and the cooperating rotating plate 9. A linear motor assembly 8 is installed at the lower side position of the installation table 6. The sliding seat 5 is slidably connected to the installation table 6 along the linear direction pointing to the roller body 2 to be processed through the linear motor assembly 8. A U-shaped pipe seat 4 corresponding to the adjustment table 3 is installed on the sliding seat 5. A cooperating gear part 301 is arranged at the inner wall position of one end of the adjustment table 3 away from the roller body 2 to be processed. The outer wall of one end of the cooperating rotating plate 9 is in internal engagement with the cooperating gear part 301.

[0031] Basic principle: The grinding action of the diamond roller is explained. Its essence is to fix the roller body 2 to be processed on the motor base 1, drive the roller body 2 to be processed to rotate at a constant speed through the motor base 1, gradually approach the roller body 2 to be processed with a fixed grinding head, and use the grinding head to trim the outer edge of the roller body 2 to be processed. Specifically, the working principle of a lathe can be referred to and combined with the Figure 1 , Figure 3And Figure 4 It will be described that a grinding head with a corresponding structure is selected according to the outer edge contour of the roller body 2 to be processed and fixed on the adjustment table 3. The adjustment table 3 is essentially in a linkage state with the sliding seat 5. Under the action of the linear motor assembly 8, the sliding seat 5 and the adjustment table 3 are driven to gradually approach the roller body 2 to be processed, so that the grinding head trims and grinds the outer edge of the roller body 2 to be processed;

[0032] The adjustment table 3 can be angularly deflected according to the outer edge contour of the roller body 2 to be processed. Specifically, through the meshing gear part 301 between the coordinated rotating plate 9 and the adjustment table 3, the coordinated rotating plate 9 is driven to rotate slightly under the action of the driving motor 10. Because the coordinated rotating plate 9 and the adjustment table 3 are in an internal meshing state, and combined with Figure 7 It will be described that the position of the coordinated rotating plate 9 corresponding to the meshing gear part 301 forms an internal roller structure relative to the adjustment table 3, and the meshing gear part 301 is essentially an internally and externally meshing gear groove. Thus, when the coordinated rotating plate 9 rotates clockwise, the adjustment table 3 will also rotate clockwise relative to the sliding seat 5, driving the grinding head to deflect slightly, so as to cooperate with the outer edge contour of the roller body 2 to be processed, and forming a multi-angle grinding method in this way.

[0033] Embodiment 2: An explanation will be given for the movement process between the adjustment table and the sliding seat:

[0034] The driving motor 10 is installed on the sliding seat 5. The coordinated rotating plate 9 is rotationally connected through the driving motor 10. An upper push rod 901 and a lower push rod 902 are respectively installed at one end of the upper surface and the other end of the lower surface of the coordinated rotating plate 9. The rotation point position of the adjustment table 3 relative to the sliding seat 5 and the center point position of the meshing gear part 301 are on the same vertical axis. A relief through groove 302 corresponding to the upper push rod 901 is provided on the adjustment table 3. The inner diameter of the relief through groove 302 is larger than the outer diameter of the upper push rod 901. The horseshoe-shaped pipe seat 4 includes an upper arc corresponding to the upper push rod 901 and a lower arc corresponding to the lower push rod 902. An inner oil pipe 402 is installed in the horseshoe-shaped pipe seat 4. Oil seal sliders 401 corresponding to the upper push rod 901 and the lower push rod 902 are slidably installed inside the upper arc and the lower arc.

[0035] Solution description: As described in the technical content of the first embodiment, because the outer edge of the diamond roller is very hard, when the grinding head gradually approaches the outer edge contour of the roller body 2 to be processed, the outer edge contour of the roller body 2 to be processed generates a lateral vibration force relative to the grinding head, especially when the grinding head is not set in a straight line relative to the lateral vibration force, resulting in the lateral vibration force being dispersed. Accurate lateral unidirectional vibration will affect the finishing effect, resulting in abnormal wear of the diamond roller. Especially for the multi-angle grinding method proposed in the present invention, the dispersed vibration force mainly acts on the adjustment table 3, thereby affecting the grinding angle. For this, the present invention optimizes the structure of the cooperative rotating plate 9, as shown below:

[0036] S1: Reference Figure 8 For explanation, when the adjustment platform 3 is rotated clockwise by a small angle through the cooperative rotating plate 9, the rotation point of the adjustment platform 3 and the sliding seat 5 remains unchanged, and the rotation point of the cooperative rotating plate 9 is only the center point of the output shaft of the driving motor 10. Figure 8 As shown, the rotation points of the adjustment table 3 and the sliding seat 5 and the center point of the output shaft of the drive motor 10 are not on the same axis, and further refer to Figure 5 , wherein the upper lever 901 performs a directional arc movement in the clearance slot 302, so that it can be understood that: the angular position of the adjustment platform 3 is specifically limited by the cooperative rotating plate 9;

[0037] S2: As shown in S1, while the cooperative rotating plate 9 rotates, the upper lever 901 and the lower lever 902 also rotate synchronously. The rotation points of the two are the center points of the output shaft of the driving motor 10, but the rotation radius of the two is different. Figure 6 and Figure 7 When the adjustment table 3 rotates clockwise, the cooperative rotating plate 9 rotates synchronously clockwise. Under the action of the upper lever 901, the oil seal slider 401 in the upper arc portion rotates clockwise inside the upper arc portion, but the lower lever 902 rotates counterclockwise under the action of the cooperative rotating plate 9, so that the oil seal slider 401 in the lower arc portion also rotates counterclockwise. Therefore, it is necessary to explain that:

[0038] The volume of the oil chamber in the upper arc portion relative to the inner oil pipe 402 is compressed, and the inner oil pipe 402 and the two oil chambers are filled with hydraulic oil or other media, but the volume of the oil chamber in the lower arc portion relative to the inner oil pipe 402 is expanded. For details, please refer to Figure 7, the piston block 404 relative to the upper arc part moves to the right due to the influence of the compression of the oil-receiving gas volume, and essentially the piston block 404 relative to the lower arc part is affected by the compression of another piston block 404 on the one hand, and on the other hand, it is also affected by the expansion of the oil cavity volume relative to the inner oil pipe 402 in the lower arc part, so the piston block 404 relative to the lower arc part moves to the left. The hydraulic oil pressure between the two piston blocks 404 can be used as the basic structure for stably adjusting the angle of the adjusting table 3. In addition, it can also indirectly feedback the vibration force of the grinding head relative to the roller body 2 to be processed. The hydraulic oil volume between the two piston blocks 404 can be injected and drained through structures such as oil pumps, which is used as the key action for controlling the deflection angle of the adjusting table 3.

[0039] In this regard, it is also necessary to ensure that the center points of the upper arc part and the lower arc part are also on the same vertical axis as the center point of the output shaft in the drive motor 10. The difference is that the radii of the upper arc part and the lower arc plate are different.

[0040] Embodiment 3: An explanation is given for the pig oil drainage action performed on the inner oil pipe inside the hoof-shaped pipe seat:

[0041] An oil cavity is provided between the oil seal slider 401 and both ends of the inner oil pipe 402. Two piston blocks 404 are slidably installed at one end inside the inner oil pipe 402. A supplementary oil port 403 corresponding to the inner oil pipe 402 is installed on the hoof-shaped pipe seat 4. The installation position of the supplementary oil port 403 is located in the middle position between the two piston blocks 404. A control module 7 is installed on the lower side of the installation table 6. The control module 7 includes an oil pump and an oil pressure detection component. The oil pump performs oil injection and drainage actions on the inner oil pipe 402 through the supplementary oil port 403.

[0042] Scheme description: Refer to Figure 5 for explanation. When the adjusting table 3 is adjusted to the relative position as shown in the figure through the coordinated rotating plate 9 and the grinding head approaches the roller body 2 to be processed, the roller body 2 to be processed will provide resistance to the grinding head. And because the rotation point position of the adjusting table 3 relative to the sliding seat 5 is closer to the roller body 2 to be processed, it is affected by the resistance of the roller body 2 to be processed relative to the grinding head, which may cause a deviation in the deflection angle of the adjusting table 3. Specifically, it is manifested that the adjusting table 3 further deflects on the basis of the preset deflection angle, thus affecting the grinding accuracy. In this regard, the relevant content in S1 and S2 in Embodiment 2 is supplemented as follows:

[0043] S3: Because the compression amount of the liquid is relatively small, when the inner oil pipe 402, both oil cavities inside, and the middle area between the two piston blocks 404 are filled with hydraulic oil, the hydraulic oil is difficult to be compressed. Therefore, when the adjusting table rotates clockwise by a certain angle, both the two oil seal sliders 401 and the piston blocks 404 will slide directionally, and further refer to Figure 6Description: The U-shaped socket 4 is in a continuous closed-loop structure. The two inner oil pipes 402 are independently arranged, and only the oil seal slider 401 is used to separate the two inner oil pipes 402. When the adjustment table 3 rotates clockwise, the inner oil pipe 402 in the corresponding clockwise direction is used as the detection structure. Specifically, the hydraulic oil pressure value between the two piston blocks 404 can be detected by the hydraulic pressure detection component.

[0044] When the adjustment table 3 is adjusted to a certain deflection angle, the two piston blocks 404 are directly locked to make their internal relative closed state. Also, the oil replenishing port 403 can be used as the access port of the oil pump and can also be used as the hydraulic pressure detection structure. When it is further deflected by the resistance of the roller body 2 to be processed, when the oil cavity in the upper arc part relative to the clockwise direction is further compressed by the oil seal slider 401 left and right, the hydraulic oil pressure in the internal space of the two piston blocks 404 will rise, so that the possible lateral vibration force generated by the roller body 2 to be processed can be directly feedback. For this, the oil injection or drainage action can be carried out in the internal area of the two piston blocks 404 to stabilize the relative position of the two oil seal sliders 401, so as to maintain the position stability of the adjustment table 3.

[0045] In summary: For the grinding process of the diamond roller, based on the principle of the lathe tooling, the grinding head gradually approaches the roller body 2 to be processed that rotates at a constant speed to perform the grinding action on the outer edge surface of the roller body 2 to be processed. For this, the linear sliding action of the sliding seat and the angle deflection action of the adjustment table are used to perform multi-angle grinding actions. Specifically, it is manifested as: the angle deflection action of the co-moving rotating plate relative to the adjustment table, and a U-shaped socket corresponding to the co-moving rotating plate is added. Inside the U-shaped socket, there are an oil seal slider and an inner oil pipe corresponding to the rotation of the co-moving rotating plate, and its internal is filled with media such as hydraulic oil with a small compression amount. The abnormal deflection action of the adjustment table is indirectly feedback by the hydraulic oil pressure, and the angle deflection process of the adjustment table is directly stabilized by the oil injection and drainage actions of the hydraulic oil, so as to maintain the grinding accuracy of the roller body 2 to be processed and avoid problems such as over-grinding or insufficient grinding amount.
