Description

Technical Field

[0001] This invention relates to the field of grinding wheel dressing technology, and in particular to a novel bonded fine grinding roll grinding wheel and its surface dressing method. Background Technology

[0002] In recent years, aluminum foil has been increasingly widely used in industries such as cigarette packaging, decoration, trademarks, food packaging and preservation, electronic components, and pharmaceuticals, with demand increasing year by year. Aluminum foil processing equipment is also constantly being upgraded. Since the thickness of aluminum foil is mainly controlled by rolling speed and foil tension during the rolling process, double rolling is necessary when the thickness reaches a certain level. The surface quality of the aluminum foil is entirely reflected in the surface quality of the rolling rolls; therefore, high-precision rolling rolls are required to meet the rolling requirements. The grinding of these high-precision rolls relies on specialized grinding wheels with special properties. Thus, researching new high-precision, high-smoothness grinding wheels has become a key aspect of developing aluminum foil processing technology.

[0003] Grinding wheels inevitably wear down during use, causing them to fail to meet technical requirements such as geometric accuracy and surface roughness. Therefore, it is essential to dress worn grinding wheels. Current grinding wheel dressing machines, however, cannot meet the increasingly demanding dressing requirements in terms of either dressing accuracy or efficiency. Furthermore, they cannot effectively control the vibrations generated during the dressing process, which negatively impacts the quality of the dressed grinding wheels. Summary of the Invention

[0004] The purpose of this invention is to provide a novel binder-bonded precision grinding roll wheel and its surface dressing method, aiming to solve the above-mentioned technical problems.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A novel surface dressing method for bonding agent-bonded precision grinding rollers includes a frame with a control console and a grinding wheel frame fixedly mounted on its upper end. A grinding wheel cover is fixedly mounted on one side of the grinding wheel frame, and a grinding wheel body is rotatably mounted inside the grinding wheel cover. A drive motor is fixedly mounted at the bottom of the frame and is connected to the grinding wheel body via a reduction gearbox. A first slide is fixedly mounted on the upper end of the frame, and a second slide is slidably mounted on the first slide. A dressing table is slidably mounted on the upper end of the second slide. A clamping seat is fixedly mounted on the dressing table, and a dressing pen is clamped and fixed inside the clamping seat. The side of the grinding wheel cover near the dressing pen has an opening for exposing part of the grinding wheel body. A diamond dressing head is provided at one end of the dressing pen facing the grinding wheel body, and an extension rod is provided at the other end of the dressing pen. A transverse vibration detection part and a vertical vibration detection part are respectively provided along the extension rod on the upper end of the dressing table.

[0007] The surface finishing method includes the following steps:

Then, the dressing table is controlled to feed laterally at a uniform speed on the second slide. The diamond dressing head is used to perform rough finishing on the surface of the grinding wheel body.

[0010] Step 3: Finishing process. Control the second slide to feed longitudinally by 0.05mm and 0.02mm in sequence. After each longitudinal feed, control the dressing table to feed transversely at a constant speed at least once. Use the diamond dressing head to finish the surface of the grinding wheel body.

[0011] Step 4: Vibration detection. During the finishing process, the transverse vibration detection unit and the longitudinal vibration detection unit are used to detect the transverse vibration and vertical vibration generated by the finishing pen when it comes into contact with the finishing process.

[0012] Step 5: End the repair. Based on the feedback data from the vibration test, if the vibration exceeds the safety threshold, the machine should be stopped immediately for inspection. If it is within the safety threshold, the repair parameters should be analyzed and adjusted accordingly after the repair is completed.

[0021] The beneficial effects of this invention are:

[0022] (1) When dressing the grinding wheel body, the surface dressing method of the present invention can adjust and control the dressing accuracy of the dressing pen by precisely controlling the longitudinal feed amount of the second slide. Combined with the accurate control of the uniform transverse feed motion of the dressing table, it can realize the progressive processing dressing process of rough dressing and fine dressing of the grinding wheel body. The operation is simple and the dressing accuracy is high.

[0023] (2) During the processing and dressing process, the transverse vibration detection unit and the longitudinal vibration detection unit respectively detect the transverse vibration and vertical vibration generated by the dressing pen when it comes into contact with the dressing. The feedback data of the vibration detection can be used to analyze whether the current dressing condition affects the dressing quality of the grinding wheel body. When the amplitude is too large or even exceeds the safety threshold, it is necessary to stop the machine in an emergency and check the grinding wheel, dressing pen and clamping fixtures to effectively identify the adverse factors that cause vibration. When the amplitude is small, it can be checked after the dressing is completed and the dressing parameters such as dressing depth can be adjusted accordingly. Real-time vibration detection can help to completely solve the vibration problem and improve the dressing quality. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1-5 As shown, this invention discloses a novel surface dressing method for bonding agent-bonded precision grinding rolls. The surface dressing method utilizes a device comprising a frame 1, with a control console 2 and a grinding wheel frame 3 fixedly mounted on the upper end of the frame 1. A grinding wheel cover 31 is fixedly mounted on one side of the grinding wheel frame 3, and a grinding wheel body 4 is rotatably mounted inside the grinding wheel cover 31. A drive motor 12 is fixedly mounted at the bottom of the frame 1, and the drive motor 12 is connected to the grinding wheel body 4 via a reduction gearbox 32. A first slide 5 is fixedly mounted on the upper end of the frame 1, and a second slide 5 is slidably mounted on the first slide 5. The slide table 6 has a dressing table 7 that is slidably mounted on its upper end. A clamping seat 71 is fixed on the dressing table 7, and a dressing pen 8 is clamped and fixed inside the clamping seat 71. The grinding wheel cover 31 has a notch on the side near the dressing pen 8 to expose part of the grinding wheel body 4. A diamond dressing head 81 is provided at one end of the dressing pen 8 facing the grinding wheel body 4, and an extension rod 82 is provided at the other end of the dressing pen 8. A transverse vibration detection part 72 and a vertical vibration detection part 73 are respectively provided along the extension rod 82 on the upper end of the dressing table 7.

[0037] Surface finishing methods include the following steps:

[0038] Step 1: Preparation for dressing. Install the grinding wheel body 4 to be dressed inside the grinding wheel cover 31, and clamp and fix the dressing pen 8 in the clamping seat 71. At the same time, use the control console 2 to complete the motion control test in advance.

[0039] Step 2: Rough finishing. Drive motor 12 drives the grinding wheel body 4 to rotate at high speed. Control the second slide 6 to feed longitudinally on the first slide 5 until the diamond dressing head 81 at the end of the dressing pen 8 approaches and contacts the grinding wheel body 4 and generates sparks. Then control the dressing table 7 to feed laterally at a uniform speed on the second slide 6 and use the diamond dressing head 81 to perform rough finishing on the surface of the grinding wheel body 4.

[0040] Step 3: Fine finishing. Control the second slide 6 to feed longitudinally by 0.05mm and 0.02mm in sequence. After each longitudinal feed, control the dressing table 7 to feed transversely at a constant speed at least once. Use the diamond dressing head 81 to perform fine finishing on the surface of the grinding wheel body 4.

[0041] Step 4: Vibration detection. During the finishing process, the transverse vibration detection unit 72 and the longitudinal vibration detection unit are used to detect the transverse and vertical vibrations generated by the finishing pen 8 when it contacts the finishing process.

[0042] Step 5: End the repair. Based on the feedback data from the vibration test, if the vibration exceeds the safety threshold, the machine should be stopped immediately for inspection. If it is within the safety threshold, the repair parameters should be analyzed and adjusted accordingly after the repair is completed.

[0043] Specifically, in the surface dressing method of the present invention, when dressing the grinding wheel body 4, the longitudinal feed amount of the second slide 6 can be precisely controlled to adjust and control the dressing accuracy of the dressing pen 8. Combined with the accurate control of the uniform transverse feed motion of the dressing table 7, the grinding wheel body 4 can achieve a progressive processing dressing process that combines rough dressing and fine dressing. The operation is simple and the dressing accuracy is high.

[0044] More specifically, during the processing and dressing process, the transverse vibration detection unit 72 and the longitudinal vibration detection unit respectively detect the transverse and vertical vibrations generated by the dressing pen 8 when it comes into contact with the dressing. The feedback data from the vibration detection can be analyzed to determine whether the current dressing condition affects the dressing quality of the grinding wheel body 4. When the amplitude is too large or even exceeds the safety threshold, an emergency stop is required, and the grinding wheel, dressing pen 8, and clamping fixtures are inspected to effectively identify the adverse factors causing the vibration. When the amplitude is small, an inspection can be carried out after the dressing is completed, and the dressing parameters such as the dressing depth can be adjusted accordingly. Real-time vibration detection can help to completely solve the vibration problem and improve the dressing quality.

[0045] like Figure 1As shown, a first lead screw pair 51 is provided inside the first slide table 5, and first slide rails 52 are provided on both sides of the upper end of the first slide table 5. The second slide table 6 is adapted to be slidably installed on the first slide rails 52 and is connected to the first lead screw pair 51 for transmission. A second lead screw pair 61 is provided inside the second slide table 6, and second slide rails 62 are provided on both sides of the upper end of the second slide table 6. The trimming table 7 is adapted to be slidably installed on the second slide rails 62 and is connected to the second lead screw pair 61 for transmission.

[0046] Specifically, in this embodiment, the first lead screw pair 51 and the second lead screw pair 61 adopt C5-grade high-precision ball screws and a high-resolution stepper motor to provide precise angular displacement control. A high-rigidity support structure (bearing housing, nut housing, etc.) is adopted to ensure that the system deforms minimally when under stress. A precision guide rail is used to support the moving parts and ensure the straightness of their motion trajectory. In addition, a high-resolution feedback system—a grating ruler—is used to eliminate the effects of lead screw thermal expansion, pitch error, etc., thereby improving the positioning accuracy to the highest level.

[0047] like Figure 5 and Figure 7 As shown, the transverse vibration detection unit 72 includes a pair of slide rods 721 and a pair of fixed frames 723. The fixed frames 723 are symmetrically arranged on both sides of the extension rod 82. The slide rods 721 slide horizontally through the fixed frames 723. An arc-shaped backing plate 722 is fixedly connected to the end of the slide rod 721. The arc-shaped backing plate 722 is adapted to abut against the outer wall of the extension rod 82. A sensing block 7211 is fixedly provided at the tail of the slide rod 721. A detection cylinder 724 is horizontally arranged on one side of the fixed frame 723. Part of the slide rod 721 extends into the detection cylinder 724. A photoelectric sensor 7241 is arranged at the bottom of the detection cylinder 724, directly facing the sensing block 7211.

[0048] Furthermore, a baffle 7212 is provided on the outer wall of the slide bar 721, and a compression spring 725 is provided between the baffle 7212 and the fixing frame 723.

[0049] Specifically, by setting a transverse vibration detection unit 72, the arc-shaped backing plate 722 will always abut against both sides of the extension rod 82 under the elastic force of the compression spring 725. When the extension rod 82 vibrates laterally, the extension rod 82 will transmit the vibration to the slide rod 721 through the arc-shaped backing plate 722, so that the slide rod 721 drives the sensing block 7211 to slide horizontally in the detection cylinder 724. At this time, the photoelectric sensor 7241 can detect the small displacement of the sensing block 7211 in real time, so that the transverse amplitude of the trimming pen 8 can be intuitively fed back through the photoelectric signal of the displacement distance.

[0050] like Figure 5 and Figure 8As shown, the vertical vibration detection unit 73 includes a fixing collar 731 and a detection frame 733. The fixing collar 731 is fixedly sleeved on the extension rod 82. A metal probe 732 is horizontally arranged on one side of the fixing collar 731. The detection frame 733 is fixed on the trimming table 7. A set of mounting frames 734 are symmetrically arranged on the upper end of the detection frame 733. A resistance coil 7341 is arranged inside the mounting frame 734. Graphite contact pieces 7321 are arranged on both sides of the metal probe 732. The metal probe 732 is inserted between the resistance coils 7341, and the graphite contact pieces 7321 and the resistance coils 7341 always maintain sliding contact. A terminal post 7342 is connected to the bottom of the resistance coil 7341. A current detector 735 is fixed on the detection frame 733. The terminal post 7342 is electrically connected to the current detector 735 through wires 7343.

[0051] Specifically, by setting up a vertical vibration detection unit 73, the metal probe 732 maintains sliding contact with the resistance coil 7341 on both sides through graphite contact pieces 7321, so that the resistance coils 7341 and the wires 7343 on both sides can form a closed detection circuit through the metal probe 732. When the trimming pen 8 vibrates vertically, the extension rod 82 will amplify its vibration amplitude and transmit the vibration to the metal probe 732 through the fixing collar 731, causing the metal probe 732 to move up and down between the resistance coils 7341, thereby changing the resistance of the resistance coils 7341 connected to the closed circuit. The longitudinal amplitude of the trimming pen 8 can then be directly fed back by detecting the change in current in the closed circuit.

[0052] like Figure 5 and Figure 6 As shown, a positioning hole 711 for the trimming pen 8 to pass through is provided through the clamping base 71. An upper abutment protrusion 7111 is fixed on the inner wall of the positioning hole 711. A set of horizontally sliding clamping blocks 712 are symmetrically arranged in the clamping base 71. A lower abutment protrusion 7121 is fixed on the side wall of the clamping block 712. The upper abutment protrusion 7111 and the lower abutment protrusion 7121 cooperate to clamp and fix the trimming pen 8. A bidirectional screw 713 is horizontally rotatably provided through the clamping base 71. The clamping block 712 is threaded through and installed at both ends of the bidirectional screw 713. A servo motor 715 is fixed on the upper end of the trimming table 7. The servo motor 715 is connected to the bidirectional screw 713 through the transmission box 714.

[0053] Specifically, by setting clamping blocks 712, when clamping the trimming pen 8, the trimming pen 8 is first inserted into the positioning hole 711. The servo motor 715 drives the bidirectional screw 713 to rotate, causing the clamping blocks 712 at both ends to gradually approach each other until the lower abutment protrusion 7121 extends into the positioning hole 711, and cooperates with the upper abutment protrusion 7111 to firmly clamp and fix the trimming pen 8. When it is necessary to remove the trimming pen 8, the servo motor 715 controls the bidirectional screw 713 to rotate in the opposite direction, and the clamping blocks 712 at both ends move in the opposite direction, thereby releasing the clamping effect on the trimming pen 8. The operation is simple and the disassembly and assembly are convenient.

[0054] like Figures 1-4 As shown, a nozzle 313 is provided at the upper end of the notch opened in the grinding wheel cover 31. The nozzle 313 is connected to the liquid supply system through the coolant pipe 311. A chip removal pipe 312 is provided at the bottom of the notch opened in the grinding wheel cover 31.

[0055] Furthermore, a coolant tank 11 is fixed on one side of the frame 1. The coolant tank 11 is located below the chip removal pipe 312. A drain pipe 112 is connected to the bottom of the coolant tank 11, and a filter plate 111 is installed at the top of the drain pipe 112.

[0056] Specifically, during the dressing process, the nozzle 313 is aimed at the area where the grinding wheel body 4 contacts the diamond dressing head 81, so that the sprayed coolant can effectively cool the grinding wheel body 4 and the diamond dressing head 81, preventing the abrasive grains from cracking under high temperature thermal stress. At the same time, it can also wash away the abrasive and adhesive debris generated during the dressing process, keeping the dressing contact surface clean. The debris and waste liquid generated during the dressing process will be discharged into the coolant tank 11 through the chip discharge pipe 312. The waste debris will be effectively filtered and blocked by the filter plate 111, while the coolant will be discharged and collected through the drain pipe 112 for recycling and reuse.

[0057] The working principle of this invention is as follows: Figures 1-9As shown, in use, the grinding wheel body 4 to be dressed is first installed inside the grinding wheel cover 31, and the dressing pen 8 is clamped and fixed in the clamping seat 71. Simultaneously, the motion control test is completed in advance using the control console 2. The drive motor 12 drives the grinding wheel body 4 to rotate at high speed, controlling the second slide 6 to feed longitudinally on the first slide 5 until the diamond dressing head 81 at the end of the dressing pen 8 approaches and contacts the grinding wheel body 4, generating a spark. Then, the dressing table 7 is controlled to feed laterally at a uniform speed on the second slide 6, using the diamond dressing head 81 to perform rough dressing on the surface of the grinding wheel body 4. The second slide 6 is controlled to feed longitudinally by 0.05mm and 0.02mm sequentially, and after each longitudinal feed, the dressing table 7 is controlled to feed laterally at a uniform speed at least once, using the diamond dressing head 81 to perform fine dressing on the surface of the grinding wheel body 4. During the dressing process, the lateral vibration detection unit 72 and the longitudinal vibration detection unit are used to detect the lateral and vertical vibrations generated by the dressing pen 8 during contact dressing, respectively. By setting a transverse vibration detection unit 72, the arc-shaped back plate 722 will always abut against both sides of the extension rod 82 under the elastic force of the compression spring 725. When the extension rod 82 vibrates laterally, the extension rod 82 will transmit the vibration to the slide rod 721 through the arc-shaped back plate 722, so that the slide rod 721 drives the sensing block 7211 to slide horizontally in the detection cylinder 724. At this time, the photoelectric sensor 7241 can detect the small displacement of the sensing block 7211 in real time, so that the transverse amplitude of the trimming pen 8 can be intuitively fed back through the photoelectric signal of the displacement distance. By setting a vertical vibration detection unit 73, the metal probe 732 maintains sliding contact with the resistance coil 7341 on both sides through graphite contact pieces 7321. This allows the resistance coils 7341 and wires 7343 on both sides to form a closed detection circuit through the metal probe 732. When the trimming pen 8 vibrates vertically, the extension rod 82 amplifies the vibration amplitude and transmits the vibration to the metal probe 732 through the fixing collar 731. This causes the metal probe 732 to move up and down between the resistance coils 7341, thereby changing the resistance of the resistance coils 7341 connected to the closed circuit. The longitudinal amplitude of the trimming pen 8 can then be directly fed back by detecting the change in current in the closed circuit. The transverse vibration detection unit 72 and the longitudinal vibration detection unit respectively detect the transverse and vertical vibrations generated by the dressing pen 8 during contact dressing. Based on the feedback data of the vibration detection, it can be analyzed whether the current dressing condition affects the dressing quality of the grinding wheel body 4. When the amplitude is too large or even exceeds the safety threshold, it is necessary to stop the machine immediately and check the grinding wheel, dressing pen 8 and clamping fixtures to effectively identify the adverse factors causing the vibration. When the amplitude is small, it can be checked after dressing is completed and the dressing parameters such as dressing depth can be adjusted accordingly.

[0058] This invention also provides a novel binder-bonded precision grinding roller wheel, such as... Figure 4As shown, the surface dressing method of the above-mentioned novel binder fine grinding roller is used for processing and dressing.

[0059] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the present invention should still fall within the scope of the present invention.
