[0003] In the prior art, including the aforementioned patents, most precision grinding equipment for cemented carbide tools has a limited rotation angle and a fixed axis, making it difficult to handle asymmetrical tools or tools requiring multi-angle machining. Furthermore, rigid contact grinding is extremely sensitive to the consistency of the tool blank and the positioning accuracy of the fixture, which can easily cause vibration or uneven grinding. In addition, the structure is complex, resulting in poor accuracy retention after wear and high maintenance costs. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] Based on this, the purpose of this invention is to provide a precision grinding equipment for cemented carbide cutting tools to solve the technical problems of limited flip angle and fixed axis, which makes it difficult to deal with asymmetrical or multi-angle machining tools, rigid contact grinding is extremely sensitive to the consistency of tool blanks and the positioning accuracy of fixtures, is prone to vibration or uneven grinding, and has a complex structure, poor accuracy retention after wear, and high maintenance costs.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a precision grinding equipment for cemented carbide tools, comprising a main body, wherein a rotating disk is disposed at the bottom of the main body, and two sets of arc-shaped tracks are disposed at the top of the rotating disk, with top plates disposed at the top of the two sets of arc-shaped tracks to cooperate with them; multiple sets of brackets are disposed at the top of the main body, and an X-axis linear module is fixed at the top of the brackets; a Y-axis linear module is disposed on one side of the X-axis linear module, and a Z-axis linear module is disposed on one side of the Y-axis linear module; a mounting plate is disposed at the bottom of the Z-axis linear module; and a universal floating mechanism is disposed at the top of the mounting plate. The universal floating mechanism includes a control seat, a protrusion, a spring, a hydraulic damper, and a universal joint; the control seat is disposed at the bottom of the mounting plate; the protrusion is disposed at the bottom of the protrusion; the spring is disposed at the bottom of the protrusion; the hydraulic damper is disposed inside the hydraulic damper; and the universal joint is disposed at the bottom of the mounting plate.

[0008] By adopting the above technical solution, after the tool is fixed, the operator selects the tool model and grinding type through the button on the outside of the main body. This process is completed through a digital selection interface. After selection, the operator starts the automatic grinding program. The logic control group first controls the rotating disk to rotate to achieve horizontal indexing and positioning. When rotation is required, the motor starts, driving the transmission rod at its output end to rotate, which in turn drives the worm gear meshing with the transmission rod. The rotation of the worm gear drives the worm wheel that is precisely matched with it. The rotating disk is fixed at the top of the worm wheel, thereby achieving precise angular displacement of the rotating disk. The worm wheel and worm gear mechanism has a reverse self-locking characteristic, which can ensure that the rotating disk is locked at any angle without the need for an additional braking device, thus ensuring indexing accuracy.

[0009] Furthermore, a motor is provided at the top of the main body, a transmission rod is sleeved at the output end of the motor, a worm is provided on the outside of the transmission rod, and a worm wheel is provided at the bottom of the rotating disk, with the worm wheel and the worm thread meshing.

[0010] By adopting the above technical solution, after the rotating disk is adjusted to the horizontal angle, the logic control group controls the top plate to adjust the pitch angle through electrical signals. The top plate and the arc-shaped track installed at its bottom are connected by a slider. The sliding of the top plate on the arc-shaped track realizes the flipping around the horizontal axis. The coordinated work of the double turntable structure - that is, the horizontal rotation of the rotating disk and the flipping of the top plate along the arc-shaped track - can accurately and quickly adjust the first tool face to be ground to the ideal position parallel to the feed plane of the grinding wheel, realizing the universal adjustment of the tool's spatial posture. It not only has good structural rigidity and is not easy to deform, but also has a direct motion path and high positioning accuracy.

[0011] Furthermore, a worm gear is provided on the outer side of the transmission rod, a worm wheel is provided at the bottom of the rotating disk, and the worm wheel is threadedly engaged with the worm gear. A linear motor is provided at the back end of the top plate, and a spindle motor is provided on one side of the Z-axis linear module.

[0012] By adopting the above technical solution, after the angle is preset, the logic control group sequentially starts the X-axis linear module, Y-axis linear module and Z-axis linear module. These three mutually orthogonal linear modules constitute a precise three-dimensional Cartesian coordinate robot. They move in coordination to quickly move the entire universal floating mechanism installed at the end of the Z-axis linear module to the vicinity of the tool edge. The universal floating mechanism integrates a control seat, a protrusion, a spring, a hydraulic damper and a universal joint as the core floating joint. Subsequently, the Z-axis linear module drives the universal floating mechanism to slowly descend, so that the high-speed rotating grinding wheel at its bottom, driven by the spindle motor, gradually approaches the tool edge. It should be noted that the spindle motor is started during the equipment startup initialization stage to ensure that the grinding wheel waits for contact at a stable linear speed.

[0013] Furthermore, a grinding wheel is provided at the bottom of the omnidirectional floating mechanism, and multiple sets of buttons are provided on the outer side of the main body.

[0014] By adopting the above technical solution, the universal floating mechanism begins to perform its core function the instant the grinding wheel contacts the cutting edge of the tool. Under the constant preload provided by multiple symmetrically arranged hydraulic dampers, the grinding wheel is pressed against the tool surface. At the same time, the universal joint at the bottom of the universal floating mechanism acts as a two-degree-of-freedom hinge center, allowing the component with the grinding wheel installed to make slight pitch and deflection in space. The spring and the hydraulic damper work together to form a dynamic balance system. The ingenuity of this system lies in the fact that it can provide continuous contact pressure through the spring and absorb the instantaneous impact and high-frequency vibration generated during the grinding process through the hydraulic damper. This allows the grinding wheel to smoothly adhere to the tool surface like a human hand and make adaptive slight oscillations with the changes in the complex cutting edge curve of the tool, thereby achieving constant pressure and perfect contact contour grinding. This mechanical adaptive design fundamentally solves the problems of over-grinding, under-grinding, or interference caused by tool setting errors or tool deformation in rigid clamping grinding, and extends the service life of the grinding wheel.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0017] (1) In the clamping and positioning stage, the unique combination structure of the V-block and the linear motor driven top plate realizes fast, accurate and universal tool fixing. The V-groove of the V-block can automatically adapt to tool shanks of different diameters. Combined with the linear motor directly driving the pin for locking, it replaces the traditional cumbersome manual screwing or complex linkage clamping mechanism. This design makes the clamping operation extremely simple, significantly reduces the preparation time, and ensures the accurate positioning of the tool center line, laying a reliable benchmark for subsequent high-precision machining, taking into account both efficiency and accuracy.

[0018] (2) In the clamping and positioning stage, the unique combination structure of the V-block and the linear motor driven top plate realizes fast, accurate and universal tool fixing. The V-groove of the V-block can automatically adapt to tool shanks of different diameters. Combined with the linear motor directly driving the pin for locking, it replaces the traditional cumbersome manual screwing or complex linkage clamping mechanism. This design makes the clamping operation extremely simple, significantly reduces the preparation time, and ensures the accurate positioning of the tool center line, laying a reliable benchmark for subsequent high-precision machining, taking into account both efficiency and accuracy.

[0019] (3) In the grinding process, the universal floating mechanism forms an intelligent mechanical adaptive system through its core universal joint hinge, symmetrically arranged springs and hydraulic dampers. This system enables the grinding wheel to closely fit the complex cutting edge surface of the tool for contour grinding under constant pressure, and also absorbs impact and vibration. Combined with the precise uniform rotation of the rotating disk, it realizes continuous, uniform and constant pressure grinding of complex cutting edges in one clamping. This pure mechanical adaptive design fundamentally solves the problems of over-grinding, under-grinding or interference caused by rigid contact. It reduces the skill requirements of operators without the need for complex sensors and closed-loop control. Attached Figure Description

[0030] like Figures 1 to 7As shown, the precision grinding equipment for carbide tools provided by the present invention includes a main body 1. A rotating disk 20 is located at the bottom of the main body 1. Two sets of arc-shaped tracks 8 are located at the top of the rotating disk 20, and top plates 9 are located at the top of the two sets of arc-shaped tracks 8 to cooperate with them. Multiple sets of supports 2 are located at the top of the main body 1. An X-axis linear module 3 is fixed to the top of the support 2. A Y-axis linear module 4 is located on one side of the X-axis linear module 3, and a Z-axis linear module 5 is located on one side of the Y-axis linear module 4. A mounting plate 12 is located at the bottom of the Z-axis linear module 5. A universal floating mechanism 6 is located at the top of the mounting plate 12. The universal floating mechanism 6 includes a control seat 601, a protrusion 602, a spring 603, a hydraulic damper 604, and a universal joint 605. The control seat 601 is located at the bottom of the mounting plate 12, the protrusion 602 is located at the bottom of the protrusion 602, the spring 603 is located at the bottom of the protrusion 602, and the hydraulic damper 605 is located at the bottom of the protrusion 602. 4. The universal joint 605 is located at the bottom of the mounting plate 12 and is installed inside the hydraulic damper 604. After the tool is fixed, the operator selects the tool model and grinding type through the button 10 on the outside of the main body 1. This process is completed through a digital selection interface. After selection, the operator starts the automatic grinding program. The logic control group 7 first controls the rotating disk 20 to rotate to achieve horizontal indexing and positioning. When rotation is required, the motor 17 starts and drives the transmission rod 14 at its output end to rotate, which in turn drives the worm gear 15 meshing with the transmission rod 14. The rotation of the worm gear 15 drives the worm wheel 13 that is precisely matched with it. The top of the worm wheel 13 is fixed to the rotating disk 20, thereby achieving precise angular displacement of the rotating disk 20. The worm wheel and worm gear mechanism has a reverse self-locking characteristic, which can ensure that the rotating disk 20 is locked at any angle without the need for an additional braking device, thus ensuring the indexing accuracy.

[0031] For example, a motor 17 is provided at the top of the main body 1, and a transmission rod 14 is sleeved at the output end of the motor 17. A worm gear 15 is provided on the outside of the transmission rod 14. A worm wheel 13 is provided at the bottom of the rotating disk 20, and the worm wheel 13 and the worm gear 15 are threadedly engaged. When the rotating disk 20 is adjusted to a horizontal angle, the logic control group 7 controls the top plate 9 to adjust the pitch angle through an electrical signal. The top plate 9 and the arc-shaped track 8 installed at its bottom are connected by a slider. The sliding of the top plate 9 on the arc-shaped track 8 realizes the flipping around the horizontal axis. The coordinated work of the double turntable structure - that is, the horizontal rotation of the rotating disk 20 and the flipping of the top plate 9 along the arc-shaped track 8 - can accurately and quickly adjust the first blade face to be ground to an ideal position parallel to the feed plane of the grinding wheel 18, realizing the universal adjustment of the tool's spatial posture. It not only has good structural rigidity and is not easily deformed, but also has a direct motion path and high positioning accuracy.

[0032] For example, a worm gear 15 is provided on the outer side of the transmission rod 14, a worm wheel 13 is provided at the bottom of the rotating disk 20, and the worm wheel 13 is threadedly engaged with the worm gear 15. A linear motor 16 is provided at the back end of the top plate 9, and a spindle motor 19 is provided on one side of the Z-axis linear module 5. After the angle is preset, the logic control group 7 sequentially starts the X-axis linear module 3, the Y-axis linear module 4, and the Z-axis linear module 5. These three mutually orthogonal linear modules constitute a precise three-dimensional Cartesian coordinate robot. They move in coordination, and the entire robot is installed at the end of the Z-axis linear module 5. The universal floating mechanism 6 at the end moves quickly to the vicinity of the cutting edge of the tool. The universal floating mechanism 6 integrates the control seat 601, the protrusion 602, the spring 603, the hydraulic damper 604, and the universal shaft 605 as the core floating joint. Subsequently, the Z-axis linear module 5 drives the universal floating mechanism 6 to slowly descend, so that the high-speed rotating grinding wheel 18 at its bottom end, driven by the spindle motor 19, gradually approaches the cutting edge of the tool. It should be noted that the spindle motor 19 is started during the initialization phase of the equipment startup to ensure that the grinding wheel 18 waits for contact at a stable linear speed.

[0033] For example, a grinding wheel 18 is provided at the bottom of the universal floating mechanism 6, and multiple sets of buttons are provided on the outer side of the main body 1. When the grinding wheel 18 contacts the cutting edge of the tool, the universal floating mechanism 6 begins to perform its core function. Under the constant preload provided by multiple symmetrically arranged hydraulic dampers 604, the grinding wheel 18 is pressed against the tool surface. Simultaneously, the universal joint 605 at the bottom of the universal floating mechanism 6 acts as a two-degree-of-freedom hinge center, allowing the component mounting the grinding wheel 18 to perform slight pitch and deflection in space. The spring 603 and the hydraulic dampers 604 work together to form... A dynamic balancing system is ingenious in that it can provide continuous contact pressure through spring 603 and absorb instantaneous impacts and high-frequency vibrations generated during grinding through hydraulic damper 604. This allows the grinding wheel 18 to smoothly adhere to the tool surface like a human hand and make adaptive micro-oscillations with the changes in the complex cutting edge curve of the tool, thereby achieving constant pressure and perfect contact contour grinding. This mechanical adaptive design fundamentally solves the problems of over-grinding, under-grinding, or interference caused by tool setting errors or tool deformation in rigid clamping grinding, and extends the service life of the grinding wheel.

[0034] The working principle and usage process of this invention: After the operator connects the main body 1 to the power supply, the alloy tool to be ground is manually placed inside the built-in V-block 11. The unique V-groove design of the V-block 11 can automatically center the tool shank of different diameters, providing excellent clamping versatility and convenience, effectively simplifying the operator's preparation work. Subsequently, the operator starts the linear motor 16 through the button 10. The linear motor 16 drives the top plate 9 to extend forward, and uses the ejector pin at its front end to firmly lock the tool in the V-block 11.

[0035] After the tool is fixed, the operator selects the tool model and grinding type using the button 10 on the outside of the main body 1. This process is completed through a digital selection interface. After selection, the operator starts the automatic grinding program. The logic control group 7 first controls the rotating disk 20 to rotate to achieve horizontal indexing and positioning. When rotation is required, the motor 17 starts, driving the transmission rod 14 at its output end to rotate, which in turn drives the worm gear 15 meshing with the transmission rod 14. The rotation of the worm gear 15 drives the worm wheel 13 that is closely matched with it. The top of the worm wheel 13 is fixed to the rotating disk 20, thereby achieving precise angular displacement of the rotating disk 20. The worm wheel and worm gear mechanism has a reverse self-locking characteristic, which can ensure that the rotating disk 20 is locked at any angle without the need for an additional braking device, thus ensuring indexing accuracy.

[0036] After the rotating disk 20 is adjusted to the horizontal angle, the logic control group 7 controls the top plate 9 to adjust the pitch angle through an electrical signal. The top plate 9 and the arc-shaped track 8 installed at its bottom are connected by a slider. The sliding of the top plate 9 on the arc-shaped track 8 realizes the flipping around the horizontal axis. The coordinated work of the double turntable structure - namely the horizontal rotation of the rotating disk 20 and the flipping of the top plate 9 along the arc-shaped track 8 - can accurately and quickly adjust the first tool face to be ground to the ideal position parallel to the feed plane of the grinding wheel 18, realizing the universal adjustment of the tool's spatial posture. It not only has good structural rigidity and is not easy to deform, but also has a direct motion path and high positioning accuracy.

[0037] After the angle preset is completed, the logic control group 7 sequentially starts the X-axis linear module 3, Y-axis linear module 4 and Z-axis linear module 5. These three mutually orthogonal linear modules constitute a precise three-dimensional Cartesian coordinate robot. They move in coordination to quickly move the entire universal floating mechanism 6 installed at the end of the Z-axis linear module 5 to the vicinity of the tool edge. The universal floating mechanism 6 integrates the control seat 601, the protrusion 602, the spring 603, the hydraulic damper 604 and the universal joint 605 as the core floating joint. Subsequently, the Z-axis linear module 5 drives the universal floating mechanism 6 to slowly descend, so that the high-speed rotating grinding wheel 18 driven by the spindle motor 19 at its bottom gradually approaches the tool edge. It should be noted that the spindle motor 19 is started during the equipment startup initialization stage to ensure that the grinding wheel 18 waits for contact at a stable linear speed.

[0038] The moment the grinding wheel 18 contacts the cutting edge of the tool, the universal floating mechanism 6 begins to perform its core function. Under the constant preload provided by multiple symmetrically arranged hydraulic dampers 604, the grinding wheel 18 is pressed against the tool surface. Simultaneously, the universal joint 605 at the bottom of the universal floating mechanism 6 acts as a two-degree-of-freedom hinge center, allowing the components mounting the grinding wheel 18 to perform slight pitch and deflection in space. The spring 603 and the hydraulic dampers 604 work together to form a dynamic balance system. The ingenuity of this system lies in… Therefore, it can provide continuous contact pressure through spring 603 and absorb the instantaneous impact and high-frequency vibration generated during the grinding process through hydraulic damper 604. This allows the grinding wheel 18 to be as smooth as a human hand to fit the tool surface and make adaptive micro-oscillations with the changes in the complex cutting edge curve of the tool. This achieves constant pressure and perfect fit contour grinding. This mechanical adaptive design fundamentally solves the problems of over-grinding, under-grinding or interference caused by tool setting error or tool deformation in rigid clamping grinding, and extends the service life of the grinding wheel.

[0039] While adaptive grinding is in progress, the rotating disk 20 begins to rotate very slowly and uniformly under the control of the logic control group 7. This slow rotational motion drives the clamped tool, causing its entire spiral cutting edge or a specific cutting edge length area to be swept uniformly relative to the high-speed rotating and adaptively fitted grinding wheel 18, thereby completing the uniform and precise grinding of the entire continuous cutting edge. This is the processing mode of "adaptive floating head cooperating with workpiece uniform rotation".

[0040] Once one cutting edge is ground, if other surfaces of the tool (such as the rake face) need to be machined, the equipment will restart the drive mechanism on the arc track 8, adjust the pitch angle of the top plate 9, and slide the slider that precisely matches the bottom of the top plate 9 with the arc track 8 to adjust the rake face of the tool to a new machining position. In the entire process, the dual rotary tables (the combination of the rotating disk 20 and the arc track 8-top plate 9) are responsible for providing precise macroscopic angle positioning, while the universal floating mechanism 6 is responsible for performing microscopic adaptive contact grinding. The two work together through the logic control group 7 to form a precise and efficient automated grinding system.
