Description

Technical Field

[0001] This invention relates to the field of diamond roller processing technology, and specifically to a fixture for fine dressing of diamond rollers. Background Technology

[0002] In diamond roller dressing, the "fixed fixture" is the cornerstone for ensuring dressing accuracy, stability, and roller life. It is not just about mechanical clamping, but a systematic engineering project that includes mechanical positioning, system rigidity, motion control, and process optimization.

[0003] Currently, the mainstream fixing methods are generally divided into two categories, requiring fine adjustments: 1. Direct spindle drive: The roller is mounted on an independent high-precision electric spindle of the dressing device or machine tool. 2. Mandrel mounting, driven rotation: The roller is mounted on a rigid support via a precision mandrel and bearing assembly, and its rotation is driven by the friction of the grinding wheel. Compared to method 1, method 2 has the advantages of relatively simple structure, lower cost, and convenient maintenance; it is suitable for most routine dressing operations, so its application is also more widespread. However, traditional diamond roller dressing is limited by site, space, and equipment precision, and cannot meet the high standard requirements for the perpendicularity of the roller end face to the axis, that is, it cannot ensure that the roller end face is precisely perpendicular to the axis. Further analysis shows that for diamond roller dressing operations, traditional fixtures cannot accurately set the initial position (tool setting) and dressing angle of the roller relative to the grinding wheel (the workpiece to be processed, such as a bearing), thereby establishing a precise coordinate system reference for different workpiece bearings to complete high-quality part processing and ensure fine dressing operations with repeatability accuracy better than 1µm. Further analysis reveals that traditional diamond roller dressing processes have a relatively simple structure and poor performance. They cannot guarantee the self-adaptability of fine-tuning their own characteristics according to process requirements, nor can they achieve the self-calibration effect of quickly establishing an accurate coordinate system after part replacement. Consequently, they cannot further improve the reliability and accuracy of the entire ultra-precision grinding process chain. Summary of the Invention

[0004] To address the shortcomings and deficiencies of existing diamond roller processing technologies, this invention provides a fixture for fine dressing of diamond rollers that ensures precise perpendicularity between the roller end face and the axis, establishes a precise coordinate system reference for bearings of different workpieces to be processed, achieves high-quality processing, and ensures repeatability positioning accuracy better than 1µm.

It can complete the fixed clamping of bearing parts of different types and sizes with different preset clamping forces, realizing the development from "passive fixing" to "free and adaptable fixtures". Furthermore, by establishing the original coordinate point through the imaging and photography module, and with the assistance of trigger switches, electric lifting rods, and electronic levels, the processing position point of the "tool" relative to the "part" can be intelligently adjusted, thereby ensuring that the roller end face is perpendicular to the axis. This allows for the precise setting of the initial position (tool setting) and dressing angle of the roller relative to the grinding wheel (the part to be processed, such as the bearing), enabling the establishment of a precise coordinate system reference for different bearing parts to be processed, so as to complete fine dressing with a repeatability accuracy of better than 1µm and high-quality part processing. This fixture, through optimized structural design and the coordination of a moving motor, guide rod, threaded rod, moving block, and laser, further softens the diamond roller before dressing the workpiece, improving the efficiency and accuracy of subsequent dressing. Additionally, a white light interferometer is incorporated to perform in-situ morphological mapping and compensation dressing of the workpiece, enhancing its adaptability to fine-tune its characteristics according to process requirements, and further improving the reliability and accuracy of the entire ultra-precision dressing process. This fixture further improves the use of coolant. By setting up a first filter screen to filter large particles generated during grinding and finishing, and a purification filter element to efficiently adsorb and filter small impurities, it further ensures the cleanliness of the coolant for recycling and reuse, achieving energy conservation and environmental protection.

[0019] 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.

[0020] Example: Figures 1 to 9 As shown: A fixture for fine dressing of diamond rollers includes a base 1 distributed on both sides, with support legs that can be installed below the bases and fixed by welding to ensure sufficient stable support. A base 2 extending forward and backward is also provided on the left side of the base 1. The base 2 is fixed to the base by welding, and reinforcing ribs can be added between them. A drive motor 201, a central shaft 202, and a clamping structure 203 are also provided on one side of the base 2. The drive motor 201 is fixedly mounted to the base 2 by a bracket. The central shaft 202 is rotatably mounted on the base 2, distributed on both sides, and connected to the drive motor 201. The central shaft and the base are connected by bearings. The clamping structure 203 is used to quickly install the bearing parts to be processed with a preset clamping force; in a preferred embodiment, such as... Figure 6 and Figure 7 As shown: The clamping structure 203 includes a clamping plate 206, a clamping column 207, an inner shaft 208, a clamping motor 209, a main wheel 216, and a secondary wheel 217. The central shaft 202 has an internal cavity 210 to provide installation space. Furthermore, the right side of the cavity 210 is provided with annularly distributed limiting grooves 211. The limiting grooves 211 have a square cross-section; this design serves to guide and limit the installation of the clamping column.

[0021] like Figure 6 As shown: The clamping motor 209 is located on one side of the cavity 210. The main wheel 216 is sleeved and installed on the output shaft of the clamping motor 209. The clamping motor is a servo-controlled motor. The fixing columns 207 are vertically distributed and their top ends pass through the matching limiting grooves 211 and are connected to the fixing plate 206. The fixing plate is a long strip structure with an arc-shaped outer surface and a rubber protective layer. It also has a toothed structure to enhance the stability of the connection with the bearing parts to be processed. The inner shaft 208 is located inside the fixing column 207, and the two are threadedly connected. The bottom end of the inner shaft 208 is connected to the auxiliary wheel 217, and the main wheel 216 and the auxiliary wheel 217 are engaged in transmission. Both the main wheel 216 and the auxiliary wheel 217 are helical gears. The fixing plate 206 is also equipped with a miniature pressure sensor 212. The fastening plate 206, fastening column 207 and limiting groove 211 are four sets that are matched and evenly distributed in a ring; and the fastening plate 206 is also provided with a high-strength wear-resistant coating.

[0022] With this setup, when the clamping motor starts rotating forward, it drives the main wheel to rotate clockwise, which in turn drives the auxiliary wheel and the inner shaft to rotate as a whole. The inner shaft and the fixing column are threaded together, and under the guidance of the limiting groove, the fixing column can only move upwards, thus moving the fixing plates outwards. In this way, multiple fixing plates move simultaneously, creating an outward expansion, which completes the internal clamping operation for the bearing. Simultaneously, a miniature pressure sensor is installed on the surface of the fixing plate to monitor the preload pressure in real time. This parameter is displayed on the control box screen. Specifically, a preset value for the preload pressure can be set during initial operation to achieve targeted clamping and fixing of different bearing models. Conversely, when the clamping motor starts rotating in reverse, it causes the fixing plates to move inwards and retract, returning to the initial state, facilitating the initial installation of the bearing parts to be processed. This fixture, through the coordination of a clamping plate, clamping column, inner shaft, clamping motor, and pressure sensor, monitors in real time whether the clamping force is within the optimal setting range, preventing it from being too tight (damaging the bearing) or too loose (causing movement). It can fix and clamp bearing parts of different types and sizes with different preset clamping forces, realizing the development from "passive fixing" to "free and adaptable fixture".

[0023] like Figure 6 As shown: In this embodiment, three evenly distributed ultrasonic vibration generators 213 are also embedded in the inner wall of the cavity 210. The purpose of this arrangement is to integrate micro-vibration sensors, improve the efficiency and accuracy of diamond roller dressing, and simultaneously monitor the vibration spectrum at the fixed end in real time. If any abnormality occurs (such as early bearing wear or balance failure), the system can issue an early warning or automatically adjust the dressing parameters. A laser 4 is also connected to one side of the base 2 via a movable structure 3 to complete the auxiliary dressing operation of the laser on the workpiece. In a preferred technical solution, such as... Figure 5 As shown: The moving structure 3 includes a moving motor 301, a guide rod 302, a threaded rod 303, and a moving block 304. The moving motor 301 is fixedly mounted on the base 2 via a bracket, and the moving motor is a servo-controlled motor. The guide rod 302 is parallel to the central axis 202, with one end connected to the base 2 and the other end connected to the connecting arm 204; the threaded rod 303 is parallel to the guide rod 302 and connected to the moving motor 301; the moving block 304 is sleeved on the guide rod 302 and the threaded rod 303, maintaining threaded rotation with the threaded rod 303 and sliding fit with the guide rod 302; the laser 4 is fixedly mounted on the moving block 304 and faces the central axis 202.

[0024] With this setup, when the moving motor starts rotating forward, it drives the threaded rod to rotate clockwise. This, in turn, with the assistance of the guide rod's limiting mechanism, moves the moving block and laser assembly to the right. When the moving motor starts rotating in reverse, it moves the moving block and laser assembly to the left. Initially, the laser corresponds to the right end face of the bearing part to be processed. This fixture, through optimized structural design and the coordinated operation of the moving motor, guide rod, threaded rod, moving block, and laser, further achieves continuous and automated softening of all outer surfaces of the workpiece before diamond roller processing, thereby improving the efficiency and accuracy of subsequent processing.

[0025] like Figure 1 and Figure 3 As shown: In this embodiment, a fixed plate 102 is connected to the right side of the base 1 via a first drive 101 to drive the fixed plate 102 to move left and right. In a preferred embodiment, the first drive 101 includes a first motor 109, a first slide rail 110, a first slider 111, a first protrusion 112, and a first rotating shaft 113. The first motor 109 is fixedly mounted to the base 1 via a bracket, and the first motor is a servo motor. The first slide rail 110 is fixedly mounted to the base 1 with screws, and the first slider 111 is disposed on the fixed plate 102, ensuring that the first slide rail 110 and the first slider 111 are matched and installed. The first protrusion 112 is disposed at the center of the fixed plate 102 and is threadedly connected to the first rotating shaft 113. The first rotating shaft 113 is rotatably disposed on the base 1, distributed left and right, and connected to the first motor 109.

[0026] With this configuration, when the first motor starts rotating forward, it drives the first rotating shaft to rotate clockwise. The first rotating shaft is threadedly engaged with the first protrusion below the fixed plate. Furthermore, under the auxiliary limiting action of the first slide rail and the first slider, the first rotating shaft will cause the entire fixed plate to move to the left. This state is primarily for the finishing and processing of the bearing parts to be processed. Conversely, when the first motor starts rotating in reverse, it will cause the entire fixed plate to move to the right and reset.

[0027] like Figure 1 and Figure 3As shown: In this embodiment, a mounting plate 104 is also connected to the fixed plate 102 via a second drive 103 to drive the mounting plate 104 to move back and forth. In a preferred embodiment, the second drive 103 includes a second motor 114, a second rotating shaft 115, a second slide rail 116, a second slider 117, and a second protrusion 118. The second motor 114 is fixedly mounted on the fixed plate 102 via a bracket, and the second motor is also a servo motor. The second rotating shaft 115 is rotatably mounted on the fixed plate 102, maintaining a front-to-back distribution, and is connected to the second motor 114. The second slide rail 116 is distributed front-to-back on the upper surface of the fixed plate 102, and the second slider 117 is mounted on the lower surface of the mounting plate 104, maintaining a matching installation between the second slider 117 and the second slide rail 116; the second protrusion 118 is located at the center of the mounting plate 104 and is threadedly connected to the second rotating shaft 115.

[0028] With this configuration, when the second motor starts rotating forward, it drives the second rotating shaft to rotate clockwise. The second rotating shaft is threadedly engaged with the second protrusion below the mounting plate. Furthermore, under the auxiliary limiting action of the second slide rail and the second slider, the second rotating shaft moves the mounting plate and diamond rollers forward as a whole. This state is primarily for positional adjustment of the bearing parts before finishing processing. Conversely, when the second motor starts rotating in reverse, it moves the mounting plate and diamond rollers backward as a whole.

[0029] like Figure 1 and Figure 4 As shown: In this embodiment, the mounting plate 104 is also connected to the mounting base 105 via the adjustment structure 7 to precisely adjust the initial position and preset adjustment angle of the setting roller 108 relative to the workpiece. In a preferred embodiment, the adjustment structure 7 includes a trigger switch 701, an electric lifting rod 702, and an electronic level 703. The trigger switch 701 is located on the upper surface of the mounting plate 104 and is connected to the electrical control box 6. There are four evenly distributed electric lifting rods 702, each connected to the trigger switch 701, and they can perform one-button lifting of all rods and single-rod lifting. The electric lifting rods are vertically mounted on the mounting plate, and their tops are hinged to the mounting base. The electronic level 703 is located on the mounting plate 104 and is connected to the trigger switch 701. The purpose of this arrangement is to solve the position adjustment problem of the working state of the trimming fixture, further ensure the level and stability of the fixture, and provide a strong foundation for subsequent precise position trimming. The system allows for both automated and manual operation via buttons on the control box or trigger switches. The electronic level is fixedly mounted on the mounting plate using a bracket, and is used to monitor the levelness of the mounting plate in real time and adapt to the varying machining angles of different bearing parts.

[0030] like Figure 1 As shown: In this embodiment, a mandrel 107 is connected to the mounting base 105 via a three-jaw chuck 106. A roller 108 is fixedly mounted on the mandrel 107 via a bearing. This arrangement ensures the stability of the diamond roller installation. The three-jaw chuck is connected to a drive device for tightening and loosening. A connecting arm 204 is also provided on one side of the base 2, distributed left and right, located above the central shaft. A camera module 205 is embedded at one end of the connecting arm 204; the camera module is aligned with the bearing mounting area. In a preferred embodiment, such as... Figure 9 As shown: The camera module 205 includes a position camera unit 214 and a compensation unit 215. The position camera unit 214 is used to photograph the bearing parts to be processed and identify their shape to establish the original coordinate origin at the rightmost edge. The position camera unit uses a high-definition camera. The compensation unit 215 uses a white light interferometer to acquire signals and transmit parameter data for in-situ topography mapping and compensation adjustment of the parts to be processed. The electrical control box 6 maintains signal connections with the camera module 205, the motor, the liquid pump 501, the laser 4, and the ultrasonic vibration generator.

[0031] A white light interferometer is further incorporated to perform in-situ morphological mapping and compensation dressing of the workpiece, improving its adaptability to fine-tune its characteristics according to process requirements and further enhancing the reliability and accuracy of the entire ultra-precision dressing process. An imaging module establishes the original coordinate points, and with the assistance of a trigger switch, electric lifting rod, and electronic level, the machining position of the "tool" relative to the "workpiece" can be intelligently adjusted. This ensures that the roller end face is perpendicular to the axis, enabling precise setting of the initial position (tool setting) and dressing angle of the roller relative to the grinding wheel (workpiece, such as a bearing). This allows for the establishment of a precise coordinate system reference for different workpiece bearings, achieving fine dressing with a repeatability accuracy better than 1µm and high-quality part machining.

[0032] like Figure 2 and Figure 8 As shown: In this embodiment, a cooling tank 5 is also provided on the base 1 and below the central axis 202. A spray pipe 502 is connected to one side of the cooling tank 5 via a liquid pump 501. The spray pipe 502 is located on the outer side of the cooling tank and runs along the connecting arm 204. A shower head 503 and a high-pressure nozzle 504 are also provided at the front end of the spray pipe 502. An electromagnetic flow control valve 505 is also provided on the spray pipe 502 to precisely control the coolant flow rate. An electrical control box 6 is also provided on one side of the base 1. Specifically, the electrical control box 6 can also be installed on a mounting base, such as... Figure 1As shown, in this embodiment, the circuit is preferably mounted on a mounting base. The electrical control box integrates a programmable controller, allowing for the editing of functional modules through a modular or embedded structure. Specific operations are based on design requirements. This section primarily protects the technical solution comprised of the mechanical structure; therefore, its principles will not be elaborated further.

[0033] like Figure 8 As shown: In a preferred embodiment, a first filter screen 506 is provided in the upper part of the cooling tank 5. The mesh diameter of the first filter screen is relatively large, mainly for filtering impurities generated during grinding. Below the first filter screen 506, a centrally recessed partition 507 is also provided, which facilitates centralized liquid treatment. A filter tube 508 is connected to the center of the partition 507; the filter tube is the carrier of the purification filter element and an important basis for transmitting purified coolant. An integrated purification filter element 509 is also provided inside the filter tube 508, wherein the purification filter element 509 includes a frame composed of non-woven fabric 510 and activated carbon particles 511 and HEPA air filter cotton 512 disposed within the non-woven fabric 510; this arrangement aims to further filter smaller impurities and micro-objects, ensuring that the coolant recycled subsequently reaches a sufficient level of cleanliness and avoiding damage to the surface of the workpiece from impurities or micro-objects. A liquid pump 513 is installed on the filter tube 508 and below the purification filter element 509. The purpose of the liquid pump is to increase the suction pressure and ensure the smooth flow of coolant from the top to the bottom for purification and storage. Both the shower head 503 and the high-pressure nozzle 504 are equipped with electromagnetic switching valves 514 at their front ends. This arrangement ensures free switching between shower operation and high-pressure operation modes. The liquid pump 501 is located inside the cooling tank 5 and below the partition 507. The purpose of the liquid pump is to deliver coolant to the nozzles, which are all facing the bearing parts to be processed.

[0034] This fixture further improves the use of coolant. A first filter screen filters out large particles generated during grinding and finishing, while a purification filter element efficiently adsorbs and filters out small impurities, ensuring the cleanliness of the coolant for recycling and reuse, thus achieving energy conservation and environmental protection. Simultaneously, it allows for free switching between a shower head and a high-pressure nozzle, suitable for cooling-rinsing during the finishing process and high-speed, high-pressure rinsing after finishing, respectively. This ensures smooth surface finishing of the workpiece and cleanliness after finishing, providing a strong foundation for subsequent fine finishing processes.
