Description

Technical Field

[0001] This invention relates to the field of diamond roller processing technology, and more specifically to a diamond roller fine grinding processing equipment. Background Technology

[0002] The grinding process in the production of diamond rollers is the most critical link in the manufacturing chain, determining the final precision and performance. It is the final precision machining of the working surface after the diamond layer of the roller has been "formed" (through electroplating, brazing, sintering, etc.). Regardless of the process used, the initially manufactured rollers require precision dressing to achieve the surface accuracy and roughness required by the drawings. However, the existing diamond roller grinding processes are not very effective and lack high precision.

[0003] A search of existing technology reveals that "CN223301493 U, a clamp for dressing diamond rollers" discloses "a clamp for dressing diamond rollers, including a base, a clamping assembly on one side of a rotating shaft, the clamping assembly including a clamping tube, a truncated cone frame fixedly connected to one end of an electric push rod, a clamping block slidably connected to the truncated cone frame via a sliding groove, and a square through hole for restricting the clamping block to slide only along the square through hole. By using the clamping assembly, the rotating shaft is brought close to the clamping tube, and the electric push rod pushes the truncated cone frame. At this time, the truncated cone frame drives multiple clamping blocks to slide along multiple sliding grooves respectively. The multiple clamping blocks will move away from the central axis of the clamping tube along multiple square through holes respectively. Then, the multiple clamping blocks stably clamp the rotating shaft from the inside. At the same time, the protrusions on the top of the multiple clamping blocks further precisely limit the rotation shaft. Using the above structure, the rotating shaft is stably clamped, which can ensure the clamping force, increase the clamping stability, facilitate the user to clamp rotating shafts and diamond rollers of different sizes, and improve the flexibility of the device."

[0004] However, the existing dressing fixtures mentioned above only provide simple clamping stability and still have some drawbacks: First, the grinding and dressing technology for rollers is limited, mostly employing the traditional grinding method, which involves using a dedicated, higher-hardness silicon carbide or diamond dressing disc (or dressing block) to grind against the diamond roller on a precision machine tool. However, the dressing disc itself is an expensive consumable, and the grinding efficiency is relatively low with limited precision; it cannot provide customized rollers with nanometer-level precision and micrometer-level feature dimensions to meet the processing needs of complex micro-components in aerospace, medical devices, and other fields. Second, as a tool for reprocessing bearings and other parts, the wear and tear on diamond rollers is considerable. Furthermore, the lifespan of traditional diamond rollers is significantly limited due to the limitations of diamond roller manufacturing processes. Third, in existing technologies, diamond rollers to be ground are mostly transported manually using trays, then picked up one-to-one and manually positioned. This method is not smooth enough, has low finishing efficiency, is time-consuming and labor-intensive, and lacks a high degree of intelligence and automation. Furthermore, the diamond rollers that have undergone initial processing after electroplating are prone to significant damage and adverse effects from impacts, posing substantial safety hazards and severely restricting the efficiency and safety of the fine grinding process of diamond rollers.

Detailed Implementation

[0020] 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.

[0021] It should be noted that, in specific embodiments of the present invention, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any actual relationship or order between these entities or operations. Furthermore, terms such as "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, the use of phrases such as "comprising one" to define an element does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0022] In the description of this invention, unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," and "equipped" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] Example: Figures 1 to 10 As shown: A diamond roller fine grinding processing device includes a base 1, with left and right sides of the base 1. A fixing plate 11 is provided on the left side of the base 1, vertically positioned and fixed by welding, with reinforcing ribs added to improve stability. A support shaft 13 is connected to the fixing plate 11 via a rotating component 12, the support shaft being distributed left and right and perpendicular to the fixing plate. To further ensure and improve the stability of the diamond roller rotation grinding and dressing process, while also considering the cost of the equipment, this invention adopts a preferred technical solution: Figure 1 As shown: The rotating component 12 includes a rotating motor 121 and a bearing 122. The bearing 122 is provided at the connection between the support shaft 13 and the fixed plate 11. The rotating motor 121 is mounted on the fixed plate 11 via a bracket and is connected to the support shaft 13. Preferably, the rotating motor is a high-speed variable frequency motor to ensure the stability of the rotating grinding of the roller to be processed.

[0024] In a preferred embodiment, the support shaft 13 is further provided with a movable and adjustable fastening element 14 to accommodate rollers of different sizes. To further optimize the fixing operation of the diamond rollers to be processed, while also considering the automated conveying and installation positioning operation of the equipment, and improving the adaptability of the installation and fixing of diamond rollers with different inner ring sizes, this invention adopts a preferred embodiment: Figure 1 and Figure 4 As shown: The fastening component 14 includes a fastening plate 141, a vertical rod 142, a first compression spring 143, a connecting block 144, a top block 145, and a first hydraulic rod 146. The vertical rods 142 are movably mounted on the support shaft 13 and are arranged in a ring; the vertical rods are perpendicular to the support shaft, primarily to support and fix the inner ring of the diamond roller to be processed. The first compression spring 143 is sleeved on the vertical rod 142 and located inside the support shaft 13; this arrangement facilitates resetting, allowing the fastening plate to return to its initial state, providing a mounting base for the subsequent installation of the next diamond roller.

[0025] like Figure 4 As shown: The fastening plate 141 is disposed at the outer end of the vertical rod 142, and the two are integrally formed. Initially, the end face of the fastening plate 141 is flush with the outer side wall of the support shaft 13. This arrangement facilitates the installation of the roller. The outer side wall of the fastening plate 141 is also provided with anti-slip texture; the purpose of this arrangement is to increase frictional resistance and increase the fastening force on the diamond roller. The connecting block 144 is disposed at the inner end of the vertical rod 142, and one side is inclined; the purpose of this arrangement is to ensure stable movement through inclined surface cooperation. The first hydraulic rods 146 are distributed left and right and disposed within the support shaft 13; the first hydraulic rods adopt a telescopic structure of hydraulic levers. The top block 145 is disposed at the end of the first hydraulic rod 146, and the top block 145 has a frustum structure. Initially, the right end face of the top block 145 is flush with the right end face of the connecting block 144. The purpose of this arrangement is to achieve a vertical fastening effect on the diamond roller.

[0026] like Figure 4As shown: To further improve the positioning and fastening effect of diamond rollers of different specifications (widths) on the support shaft 13, and to improve the efficiency of the processing equipment, the present invention adopts a preferred technical solution: the fastening component 14 further includes a top pressure block 147, a telescopic rod 148, a second compression spring 149, a base block 1410, and a second hydraulic rod 1411. The second hydraulic rod 1411 is located on the right side inside the support shaft 13 and is distributed left and right; that is, the inner cavity of the support shaft is a hollow structure, the first hydraulic rod is located on the left side, and the second hydraulic rod is located on the right side. The base block 1410 is located at the end of the second hydraulic rod 1411, and the telescopic rods 148 are located on the base block 1410, and are multiple rods evenly distributed in a ring; the telescopic rods are vertically distributed, and the second compression spring 149 is located on the telescopic rod 148 and is located inside the support shaft. The top pressure block 147 is located at the outer end of the telescopic rod 148, and its cross-section adopts a right-angled triangular structure; thus, a telescopic structure is formed. In the initial state, the top pressure block 147 is fully extended from the support shaft 13. The main purpose of this setting is to compress and shrink the roller during installation, and then reset the roller after it is misaligned with the top pressure block. Then, in the extended state of the second hydraulic rod, the horizontal clamping effect of diamond rollers of different widths is achieved. Thus, combined with the clamping force in the vertical direction, a stronger effect of positioning and clamping the diamond roller can be achieved, which improves the basic stability of the diamond roller fine grinding process.

[0027] like Figure 1As shown: In this embodiment, a mounting seat 3 is also provided on the right side of the base 1 via a moving part 2. To further improve the optimization of the diamond roller grinding process of this grinding equipment, mainly in terms of the curve matching degree of different roller surfaces to be processed, as well as the travel speed and spindle holding degree, a high-rigidity, high-speed hydrostatic spindle is used to ensure stability during dressing. The cooperation of a linear motor and a hydrostatic spindle improves the geometric accuracy, positioning accuracy, and repeatability (to the micron level) of the equipment. The present invention adopts a preferred technical solution: The moving part 2 includes a moving slide rail 21, a guide column 22, a linear motor 23, a drive shaft 24, a side wing plate 25, and a connecting seat 26. The side wing plate 25 is set on the base 1; this arrangement provides a mounting base for the centrally distributed drive shaft. The drive shaft 24 is set between the side wing plate 25 and the fixed plate 11, and the drive shaft has a threaded structure. The linear motor 23 is set on the base 1 via a bracket and is connected to the drive shaft 24. The linear motor 23 maintains a signal connection with the industrial control computer 32. The connecting seat 26 is welded to the mounting base 3 and is threadedly connected to the drive shaft 24. The movable slide rail 21 is mounted on the base 1, and the guide post 22 is mounted on the mounting base 3, ensuring that the movable slide rail 21 and the guide post 22 are matched and installed. With this configuration, the movement of the mounting base can be driven by the control of a linear motor. Specifically, when the linear motor starts rotating forward, it drives the drive shaft to rotate synchronously. Simultaneously, with the threaded engagement of the connecting seat and the auxiliary guidance of the guide post, the drive shaft drives the connecting seat and the mounting base to move as a whole to the left (initially, the mounting base is located on the right side of the base). This means that the grinding operation of the diamond roller profile to be processed is completed through the intelligent control of the industrial control computer. At the same time, when the linear motor reverses, it drives the mounting base to move to the right and reset.

[0028] like Figure 1 As shown: In this embodiment, the mounting base 3 is also equipped with a dressing machine 31, whose main function is to complete the auxiliary grinding and dressing operation of the diamond roller. An industrial control computer 32 is also connected to one side of the dressing machine 31; this industrial control computer can have a built-in programmable controller, which can realize the adaptation curve design for different diamond roller profiles through an embedded program module, thereby completing the optimized and upgraded fine grinding processing operation. In a preferred technical solution, a connecting arm 33 distributed left and right is also provided on one side of the dressing machine 31. Furthermore, in a preferred upgraded technical solution, the connecting arm can be adjusted in height, specifically through the connection of a hydraulic cylinder or similar structure. Combined with... Figure 2 As shown: A connecting rod 34 is fixedly installed on the left side of the connecting arm 33, and a dressing block 35 is installed at the lower end of the connecting rod 34; this arrangement allows the dressing block to perform grinding operations on the profile of the diamond roller. The dressing block can be a diamond dressing block with higher hardness, or a diamond grinding stone, etc. This processing also serves as the initial processing of the diamond roller by this equipment.

[0029] like Figure 2 As shown: In a preferred technical solution, an ultrafast pulsed laser 36 is also provided in the middle of the connecting arm 33. With the decrease in laser cost and the maturity of the process, ultrafast laser processing has gradually become the preferred solution for high-precision, complex-shaped roller finishing. Among them, adaptive beam shaping can adjust the spot shape and energy distribution in real time according to the processing area to optimize the processing effect. At the same time, the use of light-assisted processing and laser softening of the material to be processed can achieve "thermal coupling" processing, which can solve the problem of sharpening and shaping of extremely difficult-to-process roller surfaces. This further improves the extreme requirements for surface accuracy and consistency. The surface error of the roller will be copied 1:1 to the grinding wheel and amplified on the workpiece. Therefore, the requirements for the diamond roller profile, runout, and surface roughness are increased, and the profile accuracy is usually required to be within 1-3μm. Moreover, for the "sharpening" rather than "destruction" of the diamond roller surface particles, the ideal process should accurately remove the binder, allowing the diamond particles to be appropriately exposed (about 1 / 3 of the particle size) and maintaining the sharpness of their cutting edges, rather than crushing or pulling them out. In this embodiment, a high-pressure flushing coolant is used to assist in cooling and flushing away waste debris during the grinding process, preventing unsafe grinding of the surface by the waste debris. This process also serves as a finishing process for the diamond rollers using this equipment.

[0030] like Figure 2 and Figure 3 As shown: In a preferred embodiment, a texture laser 38 is also provided on the right side of the connecting arm 33 via a connector 37. The texture laser is a laser that uses a laser to texture the roller. The ultrafast pulse laser 36 and the texture laser 38 are respectively connected to the industrial control computer 32. To further upgrade the functionality of this grinding equipment, a convenient detachable structure is adopted, and the structure of the diamond roller product is specifically improved. The laser is used to process micron-level pits or grooves in the non-working area or specific parts of the diamond roller, serving to store coolant, improve heat dissipation, and reduce adhesion, thereby increasing service life. In a preferred embodiment, the connector 37 includes a communication jack 371, a communication plug 372, a strong magnet mother block 373, and a strong magnet daughter block 374. The communication jack 371 is located on the connecting arm 33, and the communication plug 372 is located on the texture laser 38, ensuring that the communication plug 372 and the communication jack 371 are matched and installed. The purpose of this arrangement is to ensure basic communication and power supply functions. To enhance the stability of the connection, a locking bolt can also be added for securing.

[0031] like Figure 3As shown: the strong magnet mother block 373 is disposed on the connecting arm 33, and the strong magnet daughter block 374 is disposed on the texture laser 38. The strong magnet daughter block 374 and the strong magnet mother block 373 are magnetically attached and firmly fixed. The purpose of this arrangement is to improve the convenience of disassembly and replacement installation. It further enhances the processing capability of complex surfaces and microstructures of diamond rollers. With the miniaturization and precision of products, the demand for processing micro-tooth, small radius, and free-form surfaces on rollers is increasing. The trend in diamond roller processing also requires that precision machining not only obtains geometric shapes but also endows the working surface of the roller with special functions. This processing is also a high-precision machining process for diamond rollers by this equipment. Thus, the three-step precision machining process greatly improves the surface sharpening effect of diamond rollers, improves processing accuracy, and consequently extends the service life of diamond rollers.

[0032] like Figure 1 and Figure 7 As shown: In this embodiment, a conveying component 4 is also provided on one side of the base 1. Specifically, the conveying component 4 includes a support frame 41, a first idler roller 42, a second idler roller 43, and a conveyor belt 44. The support frame 41 is distributed left and right and is located on the rear side of the base 1, and the two can be fixed by welding. The first idler roller 42 is arranged on the left side of the support frame 41 and is rotatable. The second idler roller 43 is located on the right side of the support frame 41 and is connected to a drive motor 45; the drive motor is a servo-controlled motor and can also be connected to an industrial control computer to realize automated program control. The conveyor belt 44 is arranged between the first idler roller 42 and the second idler roller 43, that is, the rotation of the idler roller drives the conveyor belt to rotate. The turning radius of the idler roller is large enough to avoid interference with the installation and movement of the positioning component base plate.

[0033] like Figure 7 and Figure 8As shown: In a preferred embodiment, multiple evenly distributed positioning elements 46 are provided on the conveyor belt 44 to adapt to the positioning of rollers of different specifications and complete the movement operation of a preset distance. To further optimize the conveying and processing of the diamond rollers to be processed, improve the automation and intelligence of the equipment, and further improve the efficiency of diamond roller grinding, this invention adopts a preferred embodiment: the positioning element 46 includes an infrared sensor 461, a base plate 462, and a positioning plate 463. The infrared sensor 461 is disposed on the base 1 and maintains a signal connection with the drive motor 45; the infrared sensor is used to monitor features under the target area in real time, specifically reflected on the conveyor belt as monitoring the encirclement of one positioning plate after another. The base plate 462 is disposed on the conveyor belt 44 and is also provided with scale lines 464; this arrangement facilitates adjustment. The positioning plate 463 has an L-shaped structure and is movably mounted on the base plate 462 and fixed to the base plate 462 by positioning bolts; multiple positioning plates 463 are arranged in a ring. In other words, the area enclosed by multiple positioning plates corresponds to the inner ring size of the diamond roller. The purpose of movable positioning plates is to form rings of different diameters to accommodate diamond rollers of different sizes, thereby improving the equipment's adaptability to various grinding processes.

[0034] like Figure 1 and Figure 5 As shown: In this embodiment, a vertically distributed fixed column 15 is also provided on one side of the base 1 via a first steering component 5. To match the processing position of the equipment process and optimize the design of the diamond roller conveying line, a 180-degree rotation design is adopted, further achieving the goal of completing roller installation immediately after rotation. The present invention adopts a preferred technical solution: the first steering component 5 includes a first servo motor 51, a main wheel 52, and a secondary wheel 53. The first servo motor 51 is mounted on the base 1. This configuration allows the servo motor to control speed with very accurate positioning, converting voltage signals into torque and speed to drive the controlled object. The main wheel 52 is sleeved and installed on the output shaft of the first servo motor 51. The fixed column 15 and the base 1 maintain a relative rotation but not relative movement relationship. The secondary wheel 53 is sleeved and installed on the fixed column 15, with the two fixedly connected, ensuring that the main wheel 52 and the secondary wheel 53 are matched and installed. The first servo motor 51 maintains a signal connection with the industrial control computer 32. With this configuration, in the initial state, the first servo motor is set to rotate at a preset angle (180 degrees). When the first servo motor starts rotating forward, it will drive the main wheel to rotate synchronously. Under the action of meshing and transmission with the auxiliary wheel, it will drive the fixed column to rotate 180 degrees.

[0035] like Figure 1As shown: In this embodiment, a rotating arm 16 is fixedly connected to the upper end of the fixed column 15, and a reinforcing rib is provided between the two. One end of the rotating arm 16 is also provided with a downwardly extending hydraulic cylinder 17. The hydraulic cylinder is used to drive the chuck structure to move up and down. The lower end of the hydraulic cylinder 17 is also provided with a chuck structure 7 through the second steering component 6, so as to drive the roller to be processed to first deflect 90 degrees in the vertical direction and then turn 180 degrees in the horizontal direction to complete the automated positioning and installation operation.

[0036] like Figure 1 and Figure 6 As shown: To achieve convenient vertical gripping of the diamond roller to be processed, while simultaneously completing rapid horizontal installation and positioning of the roller on the support shaft 13, thereby improving the operational efficiency of this device structure as an intelligent robot, the present invention adopts a preferred technical solution: The second steering component 6 includes a transmission base 61, a second servo motor 62, and a transmission arm 63. The transmission base 61 is disposed on the hydraulic cylinder 17 and has a concave structure; the transmission arm 63 is connected to the transmission base 61 via a rotating shaft. The rotating shaft and the transmission arm are fixedly connected, so that rotation of the rotating shaft will drive the transmission arm to rotate. The second servo motor 62 is fixedly mounted on the transmission base 61 via a bracket and connected to the rotating shaft. This configuration ensures that the second servo motor 62 is initialized to a preset angle (90 degrees) and guarantees counterclockwise rotation.

[0037] like Figure 1 , Figure 6 and Figure 9 As shown: To further improve the gripping stability of the diamond rollers to be processed and to adapt to the processing of diamond rollers of different sizes, the present invention adopts a preferred technical solution: the chuck structure 7 includes a chuck 71, a fixed jaw 72, a slider 73, a central turntable 74, and a chuck motor 75. The chuck 71 is disposed on the transmission arm 63 and is circular. In the initial state, the center of the chuck is consistent with the center of the enclosed circle formed by multiple positioning plates. The chuck motor 75 is mounted on the chuck 71 via a bracket, and its output shaft is connected to the central turntable 74. The chuck motor is a servo-controlled motor. Furthermore, the lower end face of the central turntable 74 is provided with a spiral-shaped groove 76. The fixing claw 72 has an L-shaped structure, and the horizontal section of the fixing claw 72 is provided with protruding teeth 77 that fit the groove 76. The inner side of the vertical section of the fixing claw 72 is provided with an anti-slip rubber pad 78. The slider 73 is disposed on the horizontal section of the fixing claw 72. The chuck 71 is provided with a sliding groove on one side, and the slider 73 is matched and installed with the sliding groove. The fixing claws 72 are multiple and evenly distributed in a ring. See details below. Figure 10The structure is shown in three dimensions. This design is derived from the common three-jaw chuck structure in machinery, aiming to achieve the synchronous movement of multiple fixed jaws as the chuck rotates. When the jaw motor starts rotating forward, it causes the multiple fixed jaws to move inward synchronously, thus completing the clamping operation on the outer ring of the diamond roller to be processed. Conversely, when the jaw starts rotating in reverse, it releases the clamping operation on the roller.

[0038] This equipment, while improving the efficiency and safety of automated diamond roller conveying operations, pursues higher surface quality and precision; it adopts seamless integration of automated operations as part of an intelligent production line; thus, the grinding and finishing process of diamond rollers is undergoing a profound transformation from a "skill" that relies on specialized equipment and experienced craftsmen to a "science" based on ultrafast lasers and intelligent control.

[0039] The working principle of precision machining of diamond rollers: Workers place the inspected diamond rollers to be processed into the area enclosed by the positioning plates on the conveyor belt. The drive motor starts, moving the conveyor belt a preset distance, specifically through signal detection and command control by auxiliary infrared sensors. The hydraulic cylinder extends a preset distance, causing the fixed claws to descend; the chuck motor starts, causing multiple clamping claws to retract, completing the clamping operation on the diamond rollers to be processed. Next, the hydraulic cylinder retracts and resets, and simultaneously, the second servo motor of the second steering component starts, causing the entire chuck structure to rotate counterclockwise by 90 degrees. Next, the first servo motor of the first steering component starts, causing the fixed column, chuck structure, and diamond rollers to be processed to rotate clockwise by 180 degrees. During this process, the diamond rollers to be processed are inserted into the support shaft. Then, the first and second servo motors start in reverse, causing the chuck structure to reset.

[0040] During the insertion of the diamond roller into the support shaft, the roller first presses against the top pressure block, causing the telescopic rod connected to the top pressure block to retract, and the second compression spring is compressed and stores energy. When the diamond roller and the top pressure block are misaligned, the second compression spring releases energy, causing the top pressure block to return to its initial state. Next, the second hydraulic rod extends, causing the base block and the top pressure block to move closer to the diamond roller and finally complete contact and clamping. In this way, the diamond roller is completely fixed in the horizontal direction. Next, the first hydraulic rod extends, and due to the engagement of the frustum-shaped top block and the inclined surface of the connecting block, it causes the vertical rod and the fastening plate to move outward as a whole, distributed at multiple points, thus completing the inner ring's clamping operation on the diamond roller, which also completes the vertical fixation of the roller.

[0041] Next, the linear motor starts rotating forward, driving the mounting base and dressing machine to move to the left, thus approaching the diamond roller to be processed. The dressing block is the first point of contact. The diamond roller begins to rotate at high speed under the starting of the rotating motor, and the dressing block also maintains high-speed rotation. Under the program control of the industrial control computer, the initial processing of the diamond roller is completed. Next, the linear motor continues rotating forward, the mounting base continues to move to the left, and the ultrafast pulse laser receives a signal from the industrial control computer and starts. Using light assistance, the laser softens the material to be processed, achieving "thermal coupling" processing, further improving the extreme requirements for surface accuracy and consistency, and increasing the processing requirements for the diamond roller's contour, runout, and surface roughness. This completes the secondary finishing of the diamond roller. Next, the linear motor continues rotating forward, the mounting base continues to move to the left, and the texture laser receives a signal from the industrial control computer and starts. Employing a convenient, detachable structure and specifically modifying the diamond roller product, the system utilizes laser technology to create micron-level pits or grooves in non-working areas or specific locations on the diamond roller. This process serves to store coolant, improve heat dissipation, and reduce adhesion. This machining process constitutes the third high-precision machining step for the diamond roller on this equipment. Then, the linear motor starts and reverses to reset the roller.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
