Description

Technical Field

[0001] This application relates to the field of roller dressing, and in particular to a high-precision diamond roller dressing device. Background Technology

[0002] Diamond rollers are commonly used for dressing grinding wheels in precision grinding. The diamond particles in the rollers replicate the precision of the grinding wheel, allowing for further cutting of the workpiece. This process can precisely remove the passivation layer and excess abrasive grains from the surface of the grinding wheel, restoring its original geometry and ensuring the accuracy of the grinding wheel's profile. Diamond rollers are characterized by high efficiency, wide applicability, and strong durability.

[0003] For example, the specification of Chinese patent CNU214025234U discloses a dressing device for a diamond roller, wherein a first motor mechanism is arranged above the base, a second motor mechanism is arranged above the first motor mechanism, and a connecting frame is arranged at one end of the first motor mechanism.

[0004] The above design solves the problem of unpleasant working environment caused by the odor generated during diamond roller dressing due to friction. However, it still has certain limitations. The device cannot perform double-sided grinding of the roller, and the roller is prone to stress imbalance, which affects the effective life of the grinding wheel. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this application is to solve the problem that the grinding device cannot perform double-sided grinding of the roller, which easily leads to the risk of stress imbalance and affects the effective life of the grinding wheel.

[0006] To address the aforementioned issues, this application provides a high-precision diamond roller dressing device, comprising a base, a column fixedly connected to the upper end of the base, a rotating structure sleeved on one side of the column, a clamping structure rotatably connected to the rotating structure, a sliding platform fixedly connected to the upper end of the base, a slide rail fixedly connected to the upper end of the sliding platform, a support frame fixedly connected to the upper end of the slide rail, a vibration damping sponge fixedly connected to the upper end of the support frame, a first bracket fixedly connected to the upper end of the vibration damping sponge, a first motor fixedly connected to the upper end of the first bracket, and a diamond working piece sleeved at the power output end of the first motor.

[0007] This application utilizes a rotating structure attached to a column and a clamping structure connected to the rotating structure to flip a diamond workpiece fitted on a first motor. Simultaneously, the rotating structure can also move up and down during the stroke of the column to change its vertical height relative to the diamond workpiece.

[0008] The diamond working part has an arc-shaped structure and is made of high-strength alloy steel or aluminum alloy. It provides mechanical support and has a precision inner hole in the center to ensure installation accuracy and facilitate the connection of the fixing sleeve in the next step.

[0009] The first motor and the second motor are servo motors, have high precision, fast response, are suitable for scenes requiring accurate positioning, have high positioning precision and angle resolution, meet micron-level profile requirements of the diamond workpiece finishing, improve finishing precision of the diamond workpiece, and have intelligent overload protection, so that the risk of locked-rotor during finishing of the hard alloy is reduced.

[0010] The slide rail adopts a high-precision roller linear guide rail, has high rigidity and high precision, has high repeatability and high running stability, has good durability and wear resistance, and is suitable for high-precision roller finishing and frequent start-stop conditions with large load.

[0011] The damping sponge plays a role in controlling vibration during operation of the first motor, reducing the influence of vibration on machining precision, absorbing high-frequency or low-frequency vibration, increasing the stability of the machining process, improving the pass rate of the workpiece surface roughness, and has the characteristics of convenient installation and low cost.

[0012] As a further improvement of the application, the diamond workpiece is sleeved with a fixing sleeve on one side, and a spring is fixedly connected to the middle section of the fixing sleeve. The fixing sleeve plays a role in stable clamping of the diamond workpiece, and also improves the positioning ability of clamping. The fixing sleeve is driven by hydraulic pressure, and the spring in the middle section of the fixing sleeve is uniformly pressed to improve the connection rigidity of the diamond workpiece and the main shaft. The spring plays a role in buffering during movement of the diamond workpiece, reduces damage to the sleeve and the main shaft, and also helps to adjust the workpiece to ensure correct contact pressure between the diamond workpiece and the grinding wheel. When the clamping force exceeds the limit, an automatic alarm will be triggered.

[0013] As a further improvement of the application, the second bracket is fixedly connected to the upper end of the base, and the second motor is fixedly connected to the upper end of the second bracket. The power output end of the second motor is sleeved with a finishing grinding wheel. The finishing grinding wheel adopts a high-rigidity main shaft system, has high repeatability and high surface finish.

[0014] As a further improvement of the application, the connecting sleeve is fixedly connected to the inner side of the support frame, and the lead screws are threadedly connected to the left and right sides of the connecting sleeve. The lead screws are fixedly connected to the fixed members at one end, and the reversers are sleeved with the lead screws and the connecting sleeve. The connecting sleeve in the middle section is threadedly connected to the lead screws, which plays a role in accurately adjusting the horizontal distance between the first motor and the second motor. The lead screws increase the operation convenience of the operator through the handle, have high positioning precision, good carrying capacity, and a long service life, and have the dual functions of motion conversion and precise transmission.

[0015] As a further improvement of this application, a liquid storage tank is fixedly connected to the inner side of the base. An opening is provided at the upper end of the liquid storage tank. A nozzle is fixedly connected to one side of the liquid storage tank, and a suction pipe is fixedly connected to the other side of the liquid storage tank. The opening at the upper end of the liquid storage tank serves to filter impurities, thereby allowing the coolant to be recycled and improving the efficiency of coolant use. The nozzle adopts a double spiral guide groove to spray coolant in the gap of diamond workpiece grinding to reduce temperature, reduce the probability of diamond graphitization, and extend the life of the roller. The suction pipe absorbs the coolant remaining in the inner hole of the diamond after cooling and guides it into the liquid storage tank for recycling. When it is necessary to cool the dressing wheel, the nozzle and suction pipe can be customized according to the structure of the dressing wheel and installed.

[0016] As a further improvement of this application, an opening is provided on the side of the diamond workpiece near the fixed sleeve to facilitate the positioning of the nozzle to the diamond workpiece.

[0017] In summary, during use, this application utilizes the rotating structure attached to the column and the clamping structure connected to the rotating structure to flip the diamond workpiece fitted on the first motor. Simultaneously, the rotating structure can move up and down during the column's stroke to change its vertical height relative to the diamond workpiece. The nozzle and suction pipe are used to cool the diamond workpiece, solving the problem that roller dressing devices cannot perform double-sided grinding of rollers, which easily leads to stress imbalance and affects the effective lifespan of the grinding wheel, thus improving the efficiency of the roller dressing equipment.

Detailed Implementation

[0031] In the description of this application, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0033] Implementation method 1:

[0034] This utility model provides a high-precision diamond roller dressing device. Please refer to [link / reference]. Figure 1 and Figures 4-7 The system includes a base 1, characterized in that a column 8 is fixedly connected to the upper end of the base 1, a rotating structure 901 is sleeved on one side of the column 8, a clamping structure 9 is rotatably connected to the rotating structure 901, a sliding platform 7 is fixedly connected to the upper end of the base 1, a slide rail 12 is fixedly connected to the upper end of the sliding platform 7, a support frame 11 is fixedly connected to the upper end of the slide rail 12, a vibration damping sponge 10 is fixedly connected to the upper end of the support frame 11, a first bracket 14 is fixedly connected to the upper end of the vibration damping sponge 10, a first motor is fixedly connected to the upper end of the first bracket 14, and a diamond working piece 5 is sleeved on the power output end of the first motor 2.

[0035] In use, first adjust the positions of the diamond workpiece 5 fixed on the first motor 2 and the dressing wheel 44 fixed on the second motor 3 so that they are in contact at an appropriate distance. Change the angle and distance by sliding the first motor 2 located on the sliding platform 77. The sliding platform 7 supports the equipment to rotate 360° on it. At the same time, start the first motor 2 and the second motor 3. After dressing for a period of time, the fixed sleeve 501 fitted on the diamond workpiece 5 can be unloaded first by using the rotating structure 901 sleeved on the column 8 and the clamping structure 9 connected to the rotating structure 901. Then remove the diamond workpiece 5 and flip it over. At the same time, the rotating structure 901 can also move up and down during the stroke of the column 8 to change the vertical height relative to the diamond workpiece 5, making it easier to clamp the diamond workpiece 5. After flipping, the clamping structure 9 first sleeves the diamond workpiece 5 on the first motor 2 and then installs the fixed structure.

[0036] The diamond working part 5 has an arc-shaped structure and is made of high-strength alloy steel or aluminum alloy. It provides mechanical support and has a precision inner hole in the center to ensure installation accuracy and facilitate the connection of the fixing sleeve 501 in the next step. As the first motor 2 is started, the diamond working part 5 rotates.

[0037] Both the first motor 2 and the second motor 3 are servo motors, which have high precision and fast response. They are suitable for scenarios that require precise positioning, with high positioning accuracy and angular resolution, meeting the micron-level contour requirements of diamond workpiece 5 and improving the dressing accuracy of diamond workpiece 5. They also have intelligent overload protection, which can reduce the risk of stalling when dressing cemented carbide.

[0038] The vibration damping sponge 10 plays a role in controlling vibration during the operation of the first motor 2, reducing the impact of vibration on machining accuracy, absorbing high-frequency or low-frequency vibration, increasing the stability of the machining process, improving the compliance rate of workpiece surface roughness, and has the characteristics of easy installation and low cost.

[0039] Please see Figure 2A fixed sleeve 501 is fitted onto one side of the diamond workpiece 5. A spring 502 is fixedly connected to the middle section of the fixed sleeve 501. The fixed sleeve 501 is hydraulically driven and can evenly clamp the diamond workpiece 5, avoiding local stress concentration. In use, after the diamond workpiece 5 is installed, the fixed sleeve 501 is connected to it, and the clamping force is controlled by the hydraulic device until it is clamped in place. The spring 502 plays a buffering role during the movement of the diamond workpiece 5. It will move accordingly according to the magnitude of the force on the diamond workpiece 5 during the grinding process. When the diamond workpiece 5 is subjected to a large force, the spring 502 shortens. When the diamond workpiece 5 is subjected to a uniform force, the spring 502 gradually returns to its default state, which can reduce damage to the sleeve and spindle. The spring 502 can also help adjust the roller to ensure the correct contact pressure between the diamond workpiece 5 and the grinding wheel. When the clamping force exceeds the limit, an automatic alarm will be triggered.

[0040] Please see Figure 3 The base 1 is fixedly connected to the upper end of the second bracket 15, and the second bracket 15 is fixedly connected to the upper end of the second motor 3. The power output end of the second motor 3 is fitted with a dressing wheel 4. The dressing wheel 4 adopts a high-rigidity spindle system with high repeatability and high surface finish. The first motor 2 and the second motor 3 need to be started at the same time to maintain good dressing efficiency.

[0041] The second implementation method:

[0042] Please see Figure 6 and Figure 10 A connecting sleeve is fixedly connected to the inner side of the support frame 11. A lead screw 13 is threadedly connected to both sides of the connecting sleeve. A fixing member is fixedly connected to one end of the lead screw 13. A reverser is sleeved on the lead screw 13 and sleeved on the inner side of the connecting sleeve. The connecting sleeve connects the two ends of the support frame 11, enabling them to move in tandem. The fixing member fixes one end of the lead screw, allowing it to slide. The lead screw 13, threaded in the middle section of the sleeve, precisely adjusts the horizontal distance between the first motor 2 and the second motor 3. The displacement of the support frame 11 is controlled by shaking the handle. The support frame 11 drives the slide rail 12 fixed on it to move, thereby achieving precise distance control. The lead screw 13, with its handle, increases the operator's ease of operation. It also has high positioning accuracy, good load-bearing capacity, and long service life, and has the dual functions of motion conversion and precise transmission.

[0043] Please see Figures 8-9A liquid storage tank 602 is fixedly connected to the inner side of the base 1. An opening is provided at the upper end of the liquid storage tank 602. A nozzle 6 is fixedly connected to one side of the liquid storage tank 602, and a suction pipe 601 is fixedly connected to the other side of the liquid storage tank 602. When the diamond grinding device completes the grinding step, the nozzle absorbs the coolant in the liquid storage tank 602 to cool the diamond workpiece 5. The suction pipe 601 absorbs the coolant remaining in the inner hole of the diamond workpiece 5 after cooling and guides it into the liquid storage tank 602. The opening at the upper end of the liquid storage tank 602 plays a role in filtering impurities, thereby allowing the coolant to be recycled and improving the efficiency of coolant use. The nozzle 6 adopts a double spiral guide groove to spray coolant in the grinding gap of the diamond workpiece 5 to reduce the temperature, reduce the probability of diamond graphitization, and extend the life of the roller. When it is necessary to cool the dressing wheel 4, the nozzle 6 and the suction pipe 601 can be customized according to the structure of the dressing wheel 4 and installed.

[0044] Please see Figure 2 An opening is provided on the side of the diamond workpiece 5 near the fixed sleeve 501 to facilitate the positioning of the nozzle 6 to the diamond workpiece 5.

[0045] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be covered within the scope of protection of this utility model.
