Description

Technical Field

[0001] The present application relates to the field of precision machinery technology, and in particular to a rapid tool setting device and method for a diamond lathe tool. Background Art

[0002] With the development of aviation and commercial lens demand, the demand for ultra-precision processing of large-aperture reflectors has become more stringent. Under the premise of meeting the accuracy of the workpiece, the efficiency requirements for processing are also getting higher and higher; the precision processing of diamond lathes plays an important role, and turning instead of grinding will be a development trend of efficient precision processing.

[0003] The machining accuracy and efficiency of precision diamond lathes are excellent, but they also require higher professional qualities of operators. Diamond tools, as the main consumables for machining, are not only related to the economic cost of production, but their accurate and efficient tool setting is also a prerequisite for ensuring product accuracy. The current tool setting process for ultra-precision diamond lathes is mainly completed by workers with rich engineering experience based on vision. If different tools are replaced or the workpiece is complex in shape, there will often be a tool setting process and its time-consuming, uncertainty in tool setting accuracy, and the final precision machining will result in major problems such as tool damage and workpiece damage.

[0004] In order to ensure strict dimensional tolerances and form and position tolerances at the same time, the tool setting accuracy of diamond tools is usually required to reach micrometers or even sub-micrometers. In addition, due to the changeable shapes of the processing objects and the consumable characteristics of the diamond tools themselves, the tool clamping device usually needs to replace the tool frequently during working hours; the diamond lathe tool installation device in the prior art mainly includes: the operator directly operates the mechanical structure to adjust the tool with the help of a tool setting microscope. This method will result in the adjustment time of different diamond tools being too long, the adjustment effect relying on the operator's experience and judgment, the non-repeatability of the final adjustment angle of the diamond tool, and the accelerated wear of the tool.

[0005] Therefore, the prior art lacks a device that can realize the rapid installation and tool setting of diamond tools, so as to reduce the dependence on the operator's experience, achieve the reproducibility of tool setting posture, and reduce the production cost of ultra-precision machining. Summary of the invention

[0006] In view of the above-mentioned shortcomings of the prior art, the present application provides a device and method for rapid tool setting of diamond lathe tools, which is applied to the field of precision machinery technology and has the advantages of realizing rapid installation and tool setting of diamond tools, reducing dependence on operator experience, improving the reproducibility of tool setting posture, and reducing the production cost of ultra-precision machining.

[0007] In the first aspect, a diamond lathe tool rapid tool setting device comprises at least: a diamond lathe base, an X-axis air-floating guide rail and a Y-axis air-floating guide rail mounted on the diamond lathe base, and a diamond tool clamping module disposed on the Y-axis air-floating guide rail;

[0011] The Y-axis air-floating guide rail drives the diamond tool to move along the Y-axis direction;

[0012] The rotating assembly drives the diamond tool to rotate around the X-axis, thereby adjusting the angle between the diamond tool and the horizontal line, so that the tip of the diamond tool is aligned with the set position of the workpiece to complete the tool setting.

[0013] The present application proposes a rapid tool setting device for diamond lathe tools. By designing a rationally structured rapid tool setting device for diamond lathe tools, the technical problem of rapid tool setting for diamond lathe tools is solved. The device includes a diamond lathe base, an X-axis air-floating guide rail, a Y-axis air-floating guide rail and a diamond tool clamping module. Among them, the diamond tool clamping module is the core part, which includes a diamond tool, a rotating assembly and a Z-axis lifting assembly. The diamond tool is driven to run along the Y-axis direction by the Y-axis air-floating guide rail, the diamond tool is driven to run along the Z-axis direction by the Z-axis lifting assembly, and the diamond tool is driven to rotate by the rotating assembly, thereby realizing the precise positioning and adjustment of the diamond tool in three-dimensional space. This design enables the tool to quickly and accurately align with the set position of the workpiece, thereby completing the tool setting process. The technical solution organically combines the air-floating guide rail, the lifting assembly and the rotating assembly to realize the precise adjustment of the tool in multiple degrees of freedom. Compared with the traditional manual tool setting method, this automated tool setting device greatly improves the tool setting efficiency and accuracy, reduces the dependence on the operator's experience, and also improves the repeatability of the tool setting process.

[0015] The present application proposes a rapid tool setting device for diamond lathe tools. By introducing an air-floating turntable, a rotational degree of freedom is added to the original Y-axis air-floating guide rail. This design enables the diamond tool clamping module to be rotated and adjusted in the horizontal direction, thereby achieving precise adjustment of the angle between the diamond tool tip and the workpiece. This adjustment capability is of great significance for improving tool setting accuracy and efficiency, especially when processing complex-shaped workpieces or requiring specific cutting angles.

[0019] The present application proposes a rapid tool setting device for diamond lathe tools, which provides the ability to accurately position the workpiece and the tool in the horizontal plane through the X-axis air-floating guide rail and the Y-axis air-floating guide rail. The Z-axis lifting assembly and the rotating assembly give the tool the ability to adjust in the vertical and rotational directions. The camera module enables the operator to observe the relative position of the tool tip and the workpiece surface in real time, thereby achieving tool setting. This design greatly reduces the reliance on operator experience, improves tool setting efficiency, and ensures the repeatability of tool setting posture. Compared with traditional manual tool setting methods, this solution not only improves accuracy and efficiency, but also reduces operating difficulty and human errors, providing reliable technical support for ultra-precision machining.

[0020] Furthermore, the diamond tool clamping module also includes a locking L-plate and a locking push rod, the locking L-plate is used to fix the handle of the diamond tool, and the locking push rod presses the handle of the diamond tool through threaded cooperation, thereby fixing the diamond tool.

[0021] Further, the diamond tool is slidably mounted on the side of the tool holder facing the workpiece through the Z-axis lifting assembly;

[0022] The tool seat has a cavity for installing a Z-axis lifting assembly, and the side has an opening connecting the cavity and the diamond tool, and the diamond tool slides along the opening through the Z-axis lifting assembly;

[0023] The Z-axis lifting assembly includes a lifting bearing seat, a lifting support bearing, a lifting servo motor, a lifting screw, a lifting transmission block, a lifting guide rail, a slider, a lifting brake and a lifting base plate;

The lifting base plate operates along the lifting guide rail with the help of the slider. The lifting brake is used to clamp the lifting guide rail to keep the diamond tool stationary.

[0026] Furthermore, the rotating assembly at least includes a screw column, a locking nut, a locking block, a rotating base plate, a rotating motor and a rotating support seat;

[0027] The rotating base plate is connected to the lifting base plate through a bearing, the locking block is pressed on the rotating base plate, the screw column passes through the locking block and the lifting base plate, and is fixed by a locking nut;

[0037] S4: driving the rotating assembly to drive the diamond tool to rotate so that the tip of the diamond tool is aligned with the set position of the workpiece to complete tool alignment.

[0038] Beneficial effect: The present application provides a rapid tool setting device and method for diamond lathe tools, which solves the technical problem of rapid tool setting for diamond lathe tools by designing a rationally structured rapid tool setting device for diamond lathe tools.

DETAILED DESCRIPTION

[0044] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application usually described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0045] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first, second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0046] In the field of ultra-precision machining, the precision machining of diamond lathes plays an important role. However, the existing diamond lathe tool setting process mainly relies on workers with rich engineering experience to complete it visually, and this method has some significant technical problems. Specifically, when it is necessary to replace different tools or process workpieces with complex shapes, the tool setting process is often time-consuming, and there is uncertainty in the tool setting accuracy. This may lead to serious problems such as tool damage or workpiece damage during precision machining turning. In addition, in order to meet strict dimensional tolerances and form and position tolerance requirements at the same time, the tool setting accuracy of diamond tools usually needs to reach the micron or even sub-micron level. However, existing tool setting methods are difficult to stably achieve such high precision requirements. In order to solve this problem, the present application proposes a diamond lathe tool rapid tool setting device and method.

[0047] Please refer to Figures 1 to 3 A diamond lathe tool quick setting device comprises at least: a diamond lathe base 5, an X-axis air-floating guide rail 6 and a Y-axis air-floating guide rail 4 mounted on the diamond lathe base 5, and a diamond tool clamping module 2 arranged on the Y-axis air-floating guide rail 4;

[0048] The X-axis air-floating guide rail 6 is used to install the workpiece;

[0049] The diamond tool clamping module 2 at least includes a tool seat 205, a Z-axis lifting assembly disposed in the tool seat 205, a diamond tool 201 connected to the Z-axis lifting assembly, and a rotating assembly 213 disposed below the diamond tool 201;

[0050] The Z-axis lifting assembly is used to drive the diamond tool 201 to move up and down along the Z-axis direction;

[0051] The Y-axis air-floating guide rail 4 drives the diamond tool 201 to move along the Y-axis direction;

[0052] The rotating assembly 213 drives the diamond tool 201 to rotate around the X-axis, thereby adjusting the angle between the diamond tool 201 and the horizontal line, so that the tip of the diamond tool 201 is aligned with the set position of the workpiece to complete the tool alignment.

[0053] The diamond lathe base 5 refers to the basic structure for supporting the entire device, and can be made of high-rigidity materials such as cast iron or composite materials to provide stable support.

[0054] The X-axis air-floating guide rail 6 and the Y-axis air-floating guide rail 4 refer to a precision guide rail system that uses gas pressure to form a thin air film to support moving parts, which can be specifically achieved by using porous medium air-floating technology or static pressure air-floating technology.

[0055] The diamond tool clamping module 2 refers to a device for fixing and adjusting the position of the diamond tool 201, which can be implemented by using a high-precision mechanical structure and a precision drive system.

[0056] The rotating assembly 213 refers to a device for driving the diamond tool 201 to rotate around its axis, which can be implemented by using a high-precision servo motor and a reduction mechanism.

[0057] The Z-axis lifting assembly refers to a device for adjusting the height of the diamond tool 201, which can be implemented by a precision screw transmission mechanism and a servo motor.

[0058] The present application organically combines air-floating guide technology, precision lifting mechanism and rotary adjustment mechanism to form an integrated diamond tool 201 rapid tool setting system. This design realizes the precise positioning and adjustment of the tool in three-dimensional space, greatly improving the efficiency and accuracy of tool setting. In particular, the application of air-floating guides significantly reduces friction during movement and improves positioning accuracy, which is crucial for achieving micron-level or even submicron-level tool setting accuracy.

[0059] Specifically, the working principle of the present application is as follows: First, the diamond lathe base 5 is used as the supporting structure of the entire device and is made of high-rigidity materials to ensure the stability of the entire system. The X-axis air-floating guide rail 6 and the Y-axis air-floating guide rail 4 are installed on the diamond lathe base 5, and are used to realize the precise movement of the workpiece and the diamond tool clamping module 2 in the horizontal plane. The air-floating guide rail supports the moving parts by forming a thin layer of air film, which significantly reduces friction and improves movement accuracy.

[0060] The diamond tool clamping module 2 is arranged on the Y-axis air-floating guide rail 4 , and includes a tool seat 205 , a Z-axis lifting assembly arranged in the tool seat 205 , a diamond tool 201 connected to the Z-axis lifting assembly, and a rotating assembly 213 arranged below the diamond tool 201 .

[0061] The Z-axis lifting assembly can use a precision screw transmission mechanism and a servo motor to accurately control the height of the tool. The rotating assembly 213 can use a high-precision servo motor and a speed reduction mechanism to achieve the rotation adjustment of the tool. This design enables the tool to be accurately positioned and adjusted in three-dimensional space.

[0062] The workpiece is arranged on the X-axis air-floating guide rail 6 and can be precisely moved in the horizontal direction. By controlling the movement of the X-axis air-floating guide rail 6 and the Y-axis air-floating guide rail 4, the relative positioning of the tool and the workpiece in the horizontal plane can be achieved.

[0063] The Z-axis lifting assembly controls the height of the diamond tool 201 so that the tip of the diamond tool 201 maintains an appropriate distance from the surface of the workpiece. In the prior art, the device for driving the diamond tool 201 to move up and down is usually arranged outside the tool holder 205 to facilitate the connection of the diamond tool 201. However, this connection method is not conducive to the stability of the connection of the diamond tool 201. In particular, when the diamond tool 201 is processed, the workpiece rotates at high speed and easily vibrates, thereby causing the Z-axis lifting assembly to deform, resulting in the inability to accurately process the workpiece. In order to solve this problem, the present application sets the Z-axis lifting assembly in the tool holder 205. On the one hand, it can reduce the additional space requirement, making the entire diamond tool clamping module 2 more compact and saving machine tool space. On the other hand, the tool holder 205 can limit the deformation of the Z-axis lifting assembly, which helps to improve the overall rigidity and stability of the tool, reduce vibration during high-speed processing, and thus improve the processing quality.

[0064] The rotating assembly 213 can adjust the angle of the diamond tool 201 to meet different processing requirements.

[0065] These components work together to achieve fast and accurate tool alignment of the diamond tool 201. Specifically, the Y-axis air-floating guide rail 4 drives the diamond tool 201 to move along the Y-axis direction, the Z-axis lifting component drives the diamond tool 201 to move along the Z-axis direction, and the rotating component 213 drives the diamond tool 201 to rotate, ultimately making the tip of the diamond tool 201 accurately align with the set position of the workpiece. The set position is the center of the workpiece.

[0066] The main reason for choosing the air bearing guide as the moving part is that it has extremely low friction coefficient and high-precision motion characteristics, which is crucial for achieving micron or even sub-micron tool setting accuracy. At the same time, the use of servo motors as the drive source can achieve fast and precise motion control, meeting the dual requirements of speed and accuracy in the tool setting process.

[0067] Furthermore, it also includes an air-floating turntable 3, which is rotatably arranged on the Y-axis air-floating guide rail 4, and is used to install the diamond tool clamping module 2, drive the diamond tool clamping module 2 to rotate in the horizontal direction, and adjust the angle between the tip of the diamond tool 201 and the workpiece so that the tip of the diamond tool 201 is aligned with the set position of the workpiece.

[0068] Among them, in the above embodiments, during the implementation of the present application, there is still the problem of adjusting the angle between the tip of the diamond tool 201 and the workpiece. In this regard, the present application provides an additional degree of rotational freedom for the diamond tool clamping module 2 by setting an air-floating turntable 3. This design enables the diamond tool clamping module 2 to be rotated and adjusted in the horizontal direction, thereby achieving precise adjustment of the angle between the tip of the diamond tool 201 and the workpiece.

[0069] The air-floating turntable 3 is rotatably arranged on the Y-axis air-floating guide rail 4, and this arrangement can be realized in a variety of ways. For example, a circular air-floating platform can be arranged on the Y-axis air-floating guide rail 4, and the air-floating turntable 3 is connected to the platform through an air-floating bearing to achieve low-friction rotational motion. Another possible implementation method is to arrange a circular track on the Y-axis air-floating guide rail 4, and the air-floating turntable 3 can cooperate with the track through a ball bearing to achieve rotational motion.

[0070] The air-floating turntable 3 is used to install the diamond tool clamping module 2, and this installation can be achieved in a variety of ways. For example, a standard T-slot or threaded hole can be set on the air-floating turntable 3, and the diamond tool clamping module 2 cooperates with these slots or holes through corresponding fixings to achieve a stable connection. Another possible way is to design a special quick connection mechanism on the air-floating turntable 3, such as a snap-on or plug-in structure, to facilitate the rapid installation and removal of the diamond tool clamping module 2.

[0071] The air-floating turntable 3 drives the diamond tool clamping module 2 to rotate in the horizontal direction. This drive can be achieved in a variety of ways. For example, a high-precision servo motor can be used to directly drive the air-floating turntable 3, and precise angle control can be achieved through a precise reduction mechanism. Another possible way is to use a stepper motor with a gear transmission mechanism to achieve indexing angle adjustment. In order to further improve the accuracy, an angle encoder can be added to the drive system to achieve closed-loop control.

[0072] The introduction of the air-floating turntable 3 forms a coordinated whole with the original Y-axis air-floating guide rail 4, diamond tool clamping module 2 and other structures. The Y-axis air-floating guide rail 4 provides basic linear motion capabilities, while the air-floating turntable 3 adds the ability of rotational adjustment on this basis. This combination not only retains the precise positioning capability of the original system, but also increases the flexibility of angle adjustment. For example, when processing a workpiece with a complex curved surface, the diamond tool 201 can be roughly positioned to the correct position through the Y-axis air-floating guide rail 4, and then fine angle adjustments can be made through the air-floating turntable 3 to keep the tool tip at the optimal cutting angle with the workpiece surface. This combination not only improves the accuracy of tool setting, but also significantly improves the efficiency of tool setting.

[0073] Furthermore, it also includes an air-floating spindle 1 and a spindle worktable 101 arranged on the air-floating spindle 1 and facing the diamond tool clamping module 2, and the spindle worktable 101 is used to fix the workpiece.

[0074] Among them, in some of the above embodiments, there are still problems with workpiece fixation and tool setting accuracy during the implementation of this application. In this regard, this application further proposes a technical solution including an air-floating spindle 1 and a spindle table 101 disposed on the air-floating spindle 1 and facing the diamond tool clamping module 2, and the spindle table 101 is used to fix the workpiece.

[0075] This technical solution solves the problems of workpiece fixation and tool setting accuracy by introducing an air-floating spindle 1 and a spindle table 101. The air-floating spindle 1 provides high-precision, low-friction rotation support, reducing vibration and errors during processing. The spindle table 101 is fixed on the air-floating spindle 1 and is set toward the diamond tool clamping module 2, ensuring the stability and positioning accuracy of the workpiece, while facilitating precise positioning and tool setting operations between the tool and the workpiece.

[0076] This design not only improves the fixing accuracy of the workpiece, but also creates conditions for the precise tool setting of the diamond tool 201. By reducing vibration and improving positioning accuracy, this technical solution can significantly improve machining accuracy, especially in ultra-precision machining that requires sub-micron precision. In addition, this design also helps to improve tool setting efficiency, reduce the operator's reliance on experience, and achieve repeatability of tool setting posture, thereby reducing the production cost of ultra-precision machining.

[0077] The innovation of this technical solution is to apply air flotation technology to the fixation of the spindle and workpiece, which not only solves the accuracy problems that may be caused by traditional mechanical fixation methods, but also improves the stability and reliability of the entire system. Compared with the existing methods that rely on operator experience and manual adjustment, this automated, high-precision fixation and tool setting method has obvious technical advantages and can better meet the demanding requirements of ultra-precision machining of large-aperture reflectors in the fields of aviation, commercial lenses, etc.

[0078] The design of the air bearing spindle 1 can be realized in a variety of ways. For example, a static air bearing or a dynamic air bearing can be used. The static air bearing provides continuous air film support through an external compressed air source, while the dynamic air bearing uses the dynamic pressure effect generated when the spindle rotates to form an air film. Both methods can effectively reduce friction and improve rotation accuracy.

[0079] The design of the spindle table 101 needs to consider the precise match with the air bearing spindle 1. The table can be made of lightweight materials, such as aviation aluminum alloy, to reduce the influence of inertia. Its surface can be processed into a precise plane, and a vacuum adsorption or mechanical clamping system can be designed to fix workpieces of different shapes and sizes. The connection between the table and the air bearing spindle 1 can be fixed with high-precision locating pins and bolts to ensure coaxiality and verticality.

[0080] The introduction of the air-floating spindle 1 and the spindle table 101 together with the diamond tool clamping module 2 form a precise machining system. The air-floating spindle 1 provides a stable rotating platform, reducing vibration and thermal deformation during machining. The spindle table 101 ensures the precise positioning and fixation of the workpiece. These two components work together with the diamond tool clamping module 2 to improve the accuracy and stability of the entire machining system.

[0081] Specifically, when performing tool setting operations, the air-floating spindle 1 can accurately control the rotational position of the workpiece, while the spindle table 101 ensures that the relative position relationship between the workpiece surface and the tool remains stable. The diamond tool clamping module 2 can be fine-tuned according to the actual position of the workpiece, thereby achieving more accurate tool setting. This synergy not only improves tool setting accuracy, but also greatly shortens tool setting time and improves processing efficiency.

[0082] Furthermore, the diamond tool clamping module 2 also includes a camera module arranged on the tool seat 205; the camera module is fixed above the tool seat 205 along the Z-axis direction, and the diamond tool 201 is fixed on the side of the tool seat 205 facing the workpiece along the Y-axis direction; the camera module is set toward the tip of the diamond tool 201 and the surface of the workpiece.

[0083] Among them, in some of the above-mentioned embodiments, during the implementation of the present application, there are still technical problems in the tool setting accuracy and efficiency of the diamond tool 201.

[0084] In this regard, the present application further proposes that the diamond tool clamping module 2 also includes a camera module disposed on the tool seat 205; wherein the camera module may be a video microscope 204. The camera module is fixed above the tool seat 205 along the Z-axis direction, and the diamond tool 201 is fixed to the side of the workpiece of the tool seat 205 along the Y-axis direction; the video microscope 204 is disposed toward the tip of the diamond tool 201 and the surface of the workpiece.

[0085] Specifically, the camera module is fixed above the tool holder 205 in the Z-axis direction. This arrangement enables the camera module to clearly capture the tip of the diamond tool 201 and the workpiece surface from a top-down angle. The diamond tool 201 is fixed on the side of the tool holder 205 facing the workpiece along the Y-axis direction. This installation method ensures that the relative position between the tool and the camera module is fixed, which is conducive to maintaining the consistency and accuracy of observation.

[0086] The camera module is set toward the tip of the diamond tool 201 and the surface of the workpiece. This directional setting enables the video microscope 204 to capture the magnified image of the tip and the workpiece surface at the same time. Thus, the operator can accurately determine the relative position and distance between the tip and the workpiece surface. This visual feedback mechanism greatly improves the accuracy and efficiency of tool setting.

[0087] For example, in actual operation, the operator can accurately control the movement of the X-axis air-floating guide rail and the Y-axis air-floating guide rail 4 through the magnified image provided by the video microscope 204, so that the tool tip is accurately aligned with the set position of the workpiece. At the same time, the adjustment of the Z-axis lifting assembly can also be more precise with the assistance of the camera module to ensure that the tool tip and the workpiece surface are on the same horizontal plane.

[0088] Furthermore, the diamond tool clamping module 2 also includes a locking L-plate 203 and a locking push rod 202. The locking L-plate 203 is used to fix the handle of the diamond tool 201. The locking push rod 202 presses the handle of the diamond tool 201 through threaded engagement, thereby fixing the diamond tool 201.

[0089] Among them, in some of the above-mentioned embodiments, there is still a problem of unstable fixation of the diamond tool 201 during the implementation of the present application.

[0090] In this regard, the present application further proposes that the diamond tool clamping module 2 also includes a locking L-plate 203 and a locking push rod 202. The locking L-plate 203 is used to fix the shank of the diamond tool 201, and the locking push rod 202 presses the shank of the diamond tool 201 through threaded cooperation, thereby fixing the diamond tool 201.

[0091] The locking L-plate 203 and the locking push rod 202 in the diamond tool clamping module 2 are key technical features for solving the problem of fixing the diamond tool 201. The locking L-plate 203 is used to fix the handle of the diamond tool 201 and provide preliminary fixed support for the tool. The locking push rod 202 passes through the threaded hole on the locking L-plate 203, and presses against the handle of the diamond tool 201 to further enhance the fixing effect. The design of the threaded fit allows the locking push rod 202 to accurately control the pressing force, ensuring that the tool is stable and will not be damaged.

[0092] The two components cooperate with each other to achieve reliable fixation of the diamond tool 201, providing a basis for subsequent precise tool setting and processing. This technical solution solves the problem of fixing the diamond tool 201 through a simple and effective mechanical structure. The locking L plate 203 provides basic support, while the locking push rod 202 achieves a stable fixation of the tool through adjustable pressure. This design not only ensures the reliability of fixation, but also has a certain degree of flexibility and can adapt to tools of different sizes.

[0093] Compared with the traditional manual adjustment method, this fixing method is more stable and reliable, reducing the error caused by human factors, and helping to improve tool setting accuracy and processing efficiency. At the same time, this fixing method also facilitates the rapid replacement of tools, thereby improving overall production efficiency. In addition, this fixing method is simple in design, easy to operate and maintain, reduces the requirements for operator skills, and is conducive to improving production standardization and consistency.

[0094] Specifically, the locking L-plate 203 can be made of high-strength alloy material, and its shape is designed to be L-shaped to provide sufficient support area. One side of the L-plate can be fixed on the tool holder 205, and the other side is used to press the handle of the diamond tool 201. The inner side of the locking L-plate 203 can be designed to be a groove matching the shape of the handle to increase the contact area and stability.

[0095] The locking push rod 202 can be made of a precision-machined threaded rod, and its material can be selected from alloy steel with good wear resistance. The thread design can adopt fine pitch thread to improve the accuracy of adjustment. One end of the push rod can be designed as a plane or a slightly raised spherical surface to ensure good contact with the handle. The other end can be designed into a shape suitable for operation with a wrench or a special tool to facilitate pressure adjustment.

[0096] In practical applications, the diamond tool 201 can be placed on the locking L-plate 203 so that the tool handle fits into the groove of the L-plate. Then, the locking push rod 202 is rotated to gradually press the tool handle. The operator can adjust the pressure of the push rod according to experience and specific needs. Generally, the pressure should be sufficient to prevent the tool from shifting during processing, but not too large to cause deformation or damage to the tool.

[0097] In order to further improve the reliability of fixation, a fine adjustment mechanism, such as a fine adjustment screw or a wedge, can be added between the locking L plate 203 and the tool holder 205 to achieve more precise position adjustment. At the same time, a force sensor can be integrated into the locking system to monitor the fixing pressure in real time to ensure that a stable clamping force is maintained during the processing.

[0098] This fixing method is not only applicable to diamond tools 201 of a single specification, but can also adapt to tools of various specifications by replacing locking L plates 203 and ejector rods of different sizes. For example, for larger tools, a wider L plate and a longer ejector rod can be used; for small tools for precision machining, a miniaturized locking assembly can be used.

[0099] Therefore, the diamond tool 201 fixing scheme of the present application has good flexibility and versatility while ensuring stability. This design not only improves the accuracy of tool setting and processing, but also greatly reduces the time for tool replacement and adjustment, thereby significantly improving the overall production efficiency.

[0100] Further, the diamond tool 201 is slidably mounted on the side of the tool holder 205 facing the workpiece via a Z-axis lifting assembly;

[0101] The tool seat 205 has a cavity for installing the Z-axis lifting assembly, and a side opening for connecting the cavity and the diamond tool 201. The diamond tool 201 slides along the opening through the Z-axis lifting assembly.

[0102] The Z-axis lifting assembly includes a lifting bearing seat 2061, a lifting support bearing 206, a lifting servo motor 208, a lifting screw 207, a lifting transmission block 209, a lifting guide rail 2101, a slider 2102, a lifting brake 2103 and a lifting base plate 211;

[0103] The lifting bearing seat 2061 is installed in the cavity and fixedly connected with the tool seat 205, the lifting support bearing 206 is connected with the lifting bearing seat 2061, the lifting screw 207 is connected with the lifting support bearing 206, the lifting transmission block 209 passes through the opening, one end is connected with the lifting screw 207, and the other end is connected with the lifting base plate 211 fixing the diamond tool 201, the lifting servo motor 208 is connected with the lifting screw 207 through a coupling, the lifting guide rail 2101 is fixed on the side, the slider 2102 is connected with the lifting guide rail 2101, and slides up and down along the lifting guide rail 2101, the lifting brake 2103 is fixedly connected with the slider 2102, and the lifting base plate 211 is fixedly connected with the slider 2102;

[0104] The lifting servo motor 208 is used to drive the lifting screw 207 to operate, thereby transmitting the movement to the lifting base plate 211 with the help of the lifting transmission block 209. The lifting base plate 211 operates along the lifting guide rail 2101 with the help of the slider 2102. The lifting brake 2103 is used to clamp the lifting guide rail 2101 to keep the diamond tool 201 stationary.

[0105] The diamond tool 201 is slidably mounted on the side of the tool holder 205 facing the workpiece through a Z-axis lifting assembly, which makes it more convenient for the diamond tool 201 to contact the workpiece for processing.

[0106] In order to prevent the Z-axis lifting assembly from being deformed due to the force applied by the high-speed rotation of the workpiece during the machining process of the diamond tool 201, the present application provides a cavity for installing the Z-axis lifting assembly in the tool seat 205. Specifically, the cavity is used to accommodate the lifting bearing seat 2061, the lifting support bearing 206 inserted in the lifting bearing seat 2061, and the lifting screw 207 connected to the lifting support bearing 206. This makes the operation of the lifting screw 207 more stable. In addition, an opening connecting the cavity and the workpiece is provided on the side of the tool seat 205 facing the workpiece, the opening extends in the Z-axis direction, and is used to set the lifting transmission block 209. One end of the lifting transmission block 209 is connected to the lifting screw 207, and the other end passes through the opening to connect the lifting base plate 211, and the lifting base plate 211 is used to fix the diamond tool 201. In the specific movement process, the lifting servo motor 208 drives the lifting screw 207 to rotate through the coupling to achieve precise lifting control. The lifting transmission block 209 converts the rotational motion of the lifting screw 207 into linear motion and transmits it to the lifting base plate 211. This drives the diamond tool 201 to move up and down along the Z axis, which saves space and avoids the vibration of the diamond tool 201 during the processing process, which causes the Z axis lifting component (especially the lifting screw 207) to deform.

[0107] In the process of implementing the present application, there is still a problem that the lifting base plate 211 is inconvenient to operate. Therefore, a lifting guide rail 2101 and a slider 2102 arranged on the lifting guide rail 2101 can be installed on the side of the tool holder 205 facing the workpiece, and the lifting base plate 211 is connected to the slider 2102, and can be conveniently operated along the lifting guide rail 2101 through the slider 2102. In particular, a lifting brake 2103 is also arranged on the lifting guide rail 2101. After the diamond tool 201 runs to a predetermined position, the lifting brake 2103 is locked to fix the position of the diamond tool 201, so as to prevent the diamond tool 201 from being displaced during the processing of the workpiece, resulting in inaccurate processing.

[0108] Through the coordinated work of the above components, the diamond tool 201 can be accurately lifted and positioned in the Z-axis direction to meet the requirements of ultra-precision machining. This technical solution solves the problem of accurate lifting and positioning of diamond lathe tools in the Z-axis direction through a precise mechanical structure and control system. The lifting servo motor 208 provides power, the lifting screw 207 and the lifting transmission block 209 convert the rotary motion into linear motion, the lifting guide rail 2101 and the slider 2102 ensure the smoothness and accuracy of the motion, and the lifting brake 2103 provides the necessary locking function.

[0109] Specifically, the design of the lifting bearing seat 2061 can be in various forms, such as an integrated structure or a split structure. The integrated structure can improve the overall rigidity, while the split structure is easy to install and maintain. The lifting support bearing 206 can be an angular contact ball bearing or a cylindrical roller bearing to provide better axial and radial support.

[0110] The lifting transmission block 209 can adopt an anti-backlash design to eliminate the axial clearance of the lifting screw 207. The lifting guide rail 2101 can be a linear rolling guide rail. The number of sliders 2102 can be selected according to the load and rigidity requirements, and two or four sliders 2102 are usually used. The lifting brake 2103 can be electromagnetic or pneumatic. The former has a fast response speed, while the latter is suitable for occasions with higher safety requirements. The material of the lifting base plate 211 can be a material with high rigidity and low thermal expansion coefficient, such as granite or carbon fiber composite material.

[0111] In practical applications, the Z-axis lifting assembly of the present application can achieve precise lifting and positioning in the following manner: First, the lifting servo motor 208 is started according to the command of the control system, and drives the lifting screw 207 to rotate through the coupling. The rotational motion of the lifting screw 207 is converted into linear motion through the lifting transmission block 209, thereby driving the lifting base plate 211 to move along the Z-axis direction. In this process, the slider 2102 slides smoothly along the lifting guide rail 2101 to ensure the linearity and stability of the motion.

[0112] When the diamond tool 201 reaches the predetermined position, the control system will send a stop signal and the lifting servo motor 208 will stop running. At this time, the lifting brake 2103 will immediately act to hold the lifting guide rail 2101 tightly and lock the entire system at the current position. This fast-response locking mechanism can effectively prevent small displacements caused by external vibrations or gravity, thereby ensuring the precise positioning of the diamond tool 201.

[0113] Furthermore, the rotating assembly 213 at least includes a screw column 2121, a locking nut 2122, a locking block 2123, a rotating base plate 2131, a rotating motor 2132 and a rotating support seat 2133;

[0114] The rotating base plate 2131 is connected to the lifting base plate 211 through a bearing, the locking block 2123 is pressed on the rotating base plate 2131, and the screw column 2121 passes through the locking block 2123 and the lifting base plate 211 and is fixed by a locking nut 2122;

[0115] The diamond tool 201 is arranged on the top of the rotating substrate 2131, and the rotating motor 2132 is arranged on the side of the lifting substrate 211 away from the rotating substrate 2131 through the rotating support seat 2133;

[0116] The rotating motor 2132 is used to drive the rotating substrate 2131 to rotate around the X-axis, thereby driving the diamond tool 201 to rotate so that the tip of the diamond tool 201 is aligned with the set position of the workpiece.

[0117] Among them, in some of the above-mentioned embodiments, during the implementation of the present application, there are still problems with the rapid and accurate tool setting and stability of the diamond tool 201. In this regard, the present technical solution realizes the rapid and accurate tool setting and stable maintenance of the diamond tool 201 by introducing multiple key components in the rotating assembly 213. The rotating base plate 2131 is connected to the lifting base plate 211 through a bearing, allowing the diamond tool 201 to rotate up and down on a vertical plane to achieve precise positioning. The locking nut 2122 and the locking pressure block 2123 are connected to the screw column 2121, and are used to press the locking pressure block 2123 on the rotating base plate 2131, so that the diamond tool 201 remains stable and motionless after the tool setting is completed. This locking mechanism ensures the stability of the tool position during the processing process. The rotating motor 2132 is connected to the lifting base plate 211 through the rotating support seat 2133, and is used to drive the rotating base plate 2131 to rotate, thereby driving the diamond tool 201 to rotate, so that the tool tip can be accurately aligned with the set position of the workpiece. This electric rotating mechanism is more accurate and efficient than manual adjustment.

[0118] Through the synergistic effect of these components, the technical solution realizes the rapid and accurate tool setting of the diamond tool 201, and can firmly lock the tool position after the tool setting is completed, solving the problems of traditional manual tool setting that is time-consuming, low-precision and poor stability. At the same time, the mechanical structure of the solution is simple and reliable, and easy to operate and maintain.

[0119] In practical applications, the selection of the rotating motor 2132 can be adjusted according to specific needs. For example, a stepper motor can be selected to achieve precise angle control, or a servo motor can be selected to obtain higher response speed and positioning accuracy. The power and torque of the motor should be selected according to the weight of the rotating substrate 2131 and the expected load to ensure that the rotating substrate 2131 can be driven to rotate smoothly.

[0120] The design of the locking mechanism can also be optimized. For example, a friction plate can be added between the locking block 2123 and the rotating base plate 2131 to increase the friction force and improve the locking effect. At the same time, a quick locking mechanism, such as an eccentric wheel locking mechanism, can be considered to further increase the speed of locking and unlocking.

[0121] This technical solution realizes fast and accurate tool alignment and stable holding of the diamond tool 201 by setting a rotating assembly 213. In actual use, the height of the diamond tool 201 is first adjusted by the Z-axis lifting assembly so that it is on the same horizontal plane as the workpiece. Then, the rotating motor 2132 drives the rotating substrate 2131 to rotate, and the angle of the diamond tool 201 is accurately adjusted so that the tool tip is aligned with the set position of the workpiece. This process can be automated and highly accurate through a high-precision angle sensor and control system.

[0122] Once the tool position is adjusted, the locking block 2123 is tightly fitted to the rotating base plate 2131 by rotating the locking nut 2122, thereby locking the tool position. This locking mechanism can provide sufficient rigidity to ensure that the tool position remains stable during the processing. At the same time, due to the use of mechanical locking, it has better reliability and energy efficiency compared to the electromagnetic locking method with continuous power supply.

[0123] Furthermore, it also includes a pressure sensor 214, which is arranged between the rotating substrate 2131 and the diamond tool 201;

[0124] The pressure sensor 214 is used to detect the pressure value of the diamond tool 201 during the process of machining the workpiece.

[0125] In some of the above-mentioned embodiments, during the implementation of the present application, there is still a technical problem of how to solve the problem of detecting tool pressure during the diamond lathe tool processing process.

[0126] In this regard, the technical solution of the present application realizes real-time and direct monitoring of the pressure of the diamond tool 201 by adding a pressure sensor 214 between the rotating substrate 2131 and the diamond tool 201. This design can solve the technical problem of detecting the tool pressure during the diamond lathe tool processing process, and provides more data support and control means for precision processing.

[0127] Specifically, the pressure sensor 214 can directly sense the pressure changes of the diamond tool 201 during the machining process. The pressure sensor 214 can be of various types, such as piezoelectric, resistive or capacitive sensors, and the appropriate type is selected according to the specific application scenario. The sensitivity and measurement range of the sensor need to be selected according to the working pressure range of the diamond tool 201 to ensure that the pressure changes can be accurately captured.

[0128] The connection between the pressure sensor 214 and the rotating substrate 2131 can be bolted or embedded to ensure stability and measurement accuracy. The direct contact between the diamond tool 201 and the pressure sensor 214 can be achieved by designing a specific contact surface or using a force transmission element to ensure that the pressure can be effectively transmitted to the sensor.

[0129] Furthermore, the diamond tool clamping module 2 also includes a horizontal reference ruler 215 , which is connected to the lifting base plate 211 , and is used to measure the angle between the diamond tool 201 and the horizontal line.

[0130] Among them, in some of the above embodiments, during the implementation of the present application, there is still a problem of how to accurately measure the angle between the diamond tool 201 and the horizontal line. In this regard, the present solution provides an objective and accurate reference for the angle measurement of the diamond tool 201 by introducing a horizontal reference ruler 215 and connecting it to the lifting base plate 211. The main function of the horizontal reference ruler 215 is to measure the angle between the diamond tool 201 and the horizontal line. This design helps to accurately control the angle of the diamond tool 201, thereby improving the accuracy of tool setting.

[0131] The design of the horizontal reference ruler 215 can be implemented in a variety of ways. For example, an electronic angle meter can be used, which can provide digital angle readings, which is convenient for operators to directly read and record. Another way is to use an arc ruler with a scale to determine the angle by observing the position of the diamond tool 201 relative to the scale. It is also possible to consider using a laser projection device to project a horizontal reference line onto the diamond tool 201 and measure by observing the angle between the projection line and the tool.

[0132] There are also multiple options for connecting the horizontal reference ruler 215 to the lifting base plate 211. A fixed connection can be used to firmly mount the horizontal reference ruler 215 on the lifting base plate 211. An adjustable connection can also be designed to allow the horizontal reference ruler 215 to adjust its position within a certain range to meet different measurement requirements. In addition, a magnetic connection can also be considered to facilitate quick installation and removal.

[0133] The introduction of the horizontal reference ruler 215 forms an organic whole with the other components of the diamond tool clamping module 2. When the Z-axis lifting assembly adjusts the height of the diamond tool 201, the horizontal reference ruler 215 moves accordingly, always maintaining a relative position with the tool. This design ensures that the tool angle can be accurately measured at any height. At the same time, the presence of the horizontal reference ruler 215 will not interfere with the operation of the rotating assembly 213, allowing the tool to be rotated and adjusted while measuring the angle.

[0134] In actual application, the operator can use the horizontal reference ruler 215 by following the steps below: First, install the diamond tool 201 on the diamond tool clamping module 2. Then, adjust the Z-axis lifting assembly to make the tool reach the required working height. Next, use the horizontal reference ruler 215 to measure the angle between the tool and the horizontal line. If the angle does not meet the requirements, the angle of the tool can be fine-tuned by the rotating assembly 213, and the horizontal reference ruler 215 can be used again to verify until the required precise angle is reached.

[0135] The use of the horizontal reference ruler 215 significantly improves the accuracy and efficiency of tool setting. It provides an objective and accurate angle reference for the operator, reduces human error, and improves tool setting efficiency. In addition, this design helps to standardize the tool setting process so that different operators can achieve the same tool setting accuracy, thereby improving the consistency of processing quality.

[0136] Please refer to Figure 4 A diamond lathe tool quick tool setting method is applied to any of the above-mentioned diamond lathe tool quick tool setting devices, and the method comprises:

[0137] S1: Drive the X-axis air-floating guide rail 6 to fix the workpiece at a preset position;

[0138] S2: driving the Y-axis air-floating guide rail 4 to drive the diamond tool clamping module 2 to run along the Y-axis direction so that the diamond tool 201 is aligned with the workpiece;

[0139] S3: driving the Z-axis lifting assembly to drive the diamond tool 201 to move up and down along the Z-axis direction, so that the tip of the diamond tool 201 and the set position of the workpiece are on the same horizontal plane;

[0140] S4: driving the rotating assembly 213 to drive the diamond tool 201 to rotate around the X-axis so that the tip of the diamond tool 201 is aligned with the set position of the workpiece to complete the tool setting.

[0141] The method forms a systematic and automated tool setting process through the organic combination of multiple precision control components. This combination not only solves the problems of low efficiency and unstable precision in traditional tool setting methods, but also provides a new solution for the field of ultra-precision machining, which helps to improve overall machining efficiency and product quality.

[0142] The diamond lathe tool rapid tool setting method of the present application involves multiple technical features, including the X-axis air-floating guide rail 6, the Y-axis air-floating guide rail 4, the Z-axis lifting assembly and the rotating assembly 213. These features play an important role in achieving rapid tool setting.

[0143] Specifically, the X-axis air-floating guide rail 6 is used to accurately position the workpiece to ensure that the workpiece is fixed at a preset position. The preset position is a manually set workpiece processing position. This step can be achieved through high-precision motion control of the air-floating guide rail.

[0144] The Y-axis air-floating guide rail 4 drives the diamond tool clamping module 2 to achieve precise positioning of the tool in the Y-axis direction. This step can be controlled in a similar way to the X-axis, but the weight and motion characteristics of the tool clamping module need to be taken into account. For example, a servo motor can be used in conjunction with a high-precision reducer to achieve precise motion control in the Y-axis direction.

[0145] The Z-axis lifting assembly is used to adjust the tool height so that the tool tip is at the same level as the workpiece setting position. This step may involve higher precision requirements because the tool height directly affects the processing accuracy. You can consider using precision drive devices such as precision electric cylinders, combined with high-resolution displacement sensors, to achieve nanometer-level height adjustment.

[0146] The rotating assembly 213 is used to fine-tune the tool angle to ensure that the tool tip is accurately aligned with the set position of the workpiece. This step can use a high-precision rotating platform, such as a rotating platform supported by an air bearing, in conjunction with a high-resolution angle encoder to achieve precise adjustment of the tool angle.

[0147] Further, in the present application, a more specific implementation method is as follows: when the diamond lathe officially starts to process the workpiece, the workpiece to be processed is first fixed to the spindle worktable 101, and the diamond tool clamping module 2 is as shown in the attached Figure 2 The installation is completed in sequence as shown. In this design, the locking position of the locking L plate 203 is relatively large, and it can meet the clamping requirements of the diamond tool 201 handles of different sizes in combination with the locking push rod 202. When setting the tool, the operator first observes with the naked eye whether the diamond tool 201 is roughly in the center of the workpiece. If there is a large deviation, the Y-axis air-floating guide rail and the X-axis air-floating guide rail are controlled to move respectively, so that the tip of the diamond tool 201 is close to the set position of the workpiece, that is, the center position of the workpiece, until the tip of the diamond tool 201 and the center of the workpiece are displayed under the field of view of the video microscope 204.

[0148] Start fine tool alignment: Through the magnification of the video microscope 204, further observe the positional relationship between the tip of the diamond tool 201 and the center of the workpiece. According to the observation results, the tip of the diamond tool 201 is placed directly above or directly below the center of the workpiece through the rotation of the air-floating turntable 3. When the tip of the tool is below the center of the workpiece, the lifting servo motor 208 starts to rotate forward, driving the lifting screw 207 to move, thereby transmitting the movement to the lifting base plate 211 with the help of the lifting transmission block 209; at this time, the lifting base plate 211 starts to rise along the lifting guide rail 2101 with the help of the slider 2102, until the video microscope 204 shows that the tip of the diamond tool 201 has approached the center of the workpiece, the lifting stops, and at this time, the lifting brake 2103 starts to close and clamp, so that the height of the diamond tool 201 remains unchanged; if it is observed that the tip of the tool is above the center of the workpiece when fine tool alignment starts, the lifting servo motor 208 is driven to rotate in the opposite direction until the lifting brake 2103 is closed and clamped. After completing the height matching, according to the different types of diamond tool 201 and the characteristics of the processed material, the angle between the tip of the diamond tool 201 and the horizontal line is adjusted according to the expected angle value; under the video microscope 204, the angle value formed between the tip of the diamond tool 201 and the horizontal reference ruler 215 is detected at this time. If this angle value deviates from the expected processing angle, the rotating motor 2132 starts to rotate, and drives the rotating substrate 2131 to rotate through the bearing and the coupling until the angle between the tip of the diamond tool 201 and the horizontal reference ruler 215 is within the expected processing angle range; after the angle adjustment is completed, the rotating substrate 2131 is locked. In this device, a pair of locking components are designed. By locking the locking nut 2122, the locking block 2123 presses the rotating substrate 2131. At this point, the angle adjustment is completed. Since the tool angle has changed, it is determined again under the video microscope 204 whether the tool tip is at the center point of the workpiece. If not, repeat the initial step and adjust the lifting servo motor 208 until the tool meets the requirements.

[0149] After the diamond tool 201 is aligned, the workpiece trial cutting begins. In this device, the closed loop of the tool alignment process is realized by setting the pressure sensor 214; the expected force value of the diamond tool 201 during precision cutting is set according to the material of the workpiece, the feed speed during workpiece processing, and the rotation speed of the air-floating spindle 1. During the trial cutting, the pressure feedback value of the pressure sensor 214 is detected and compared with the expected force value. The smaller the pressure feedback value, the more it can be basically judged whether the relative height and angle between the diamond tool 201 and the workpiece alignment point are the optimal values; if the resistance of the diamond tool 201 exceeds the expected set pressure value during the trial cutting, the tool posture parameters can be adjusted through the lifting mechanism and the rotating mechanism until the tool force is within the expected range; at this point, the precision alignment of the diamond tool 201 is completed. By accurately aligning the tool and ensuring that the tool force is minimized, the tool loss can be saved to the greatest extent and the product manufacturing cost can be reduced.
