[0030] Embodiment 1

[0031] Referring to Figures 1-5 As shown, an automatic milling wheel device applied to a grinding machine of the present utility model is installed on a spindle support plate 1. The spindle support plate 1 is vertically movably arranged on a column 18 of the grinding machine. A hydrostatic spindle 2 is installed inside the spindle support plate 1. Both ends of the hydrostatic spindle 2 are respectively connected to a power assembly and a grinding wheel 3. Among them, the grinding wheel 3 is suspended above a workbench 19 of the grinding machine. The column 18 is arranged away from the workbench 19. The hydrostatic spindle 2 is installed perpendicular to the column 18. The hydrostatic spindle 2 is arranged in a cavity of the spindle support plate 1. The spindle support plate 1 is slidably arranged on the side of the column 18 and is suspended by a pull rope. The height position of the spindle support plate 1 is adjusted by applying a pulling force through stretching. The power assembly includes a motor and its deceleration mechanism, which are conventional components and can be directly selected or ordered from the market according to the required parameters and will not be elaborated here.

[0032] The automatic milling wheel device of the present application includes a die repairing member. The die repairing member is installed on a lifting assembly and adjusts the height between it and the grinding wheel 3, that is, the height of the die repairing member can be adjusted to abut against the grinding wheel 3; a horizontal reciprocating displacement mechanism. The horizontal reciprocating displacement mechanism includes a mounting plate 5 fixed with the lifting assembly. The mounting plate 5 is slidably installed on the spindle support plate 1 through a crank-slider 17 assembly. The reciprocating sliding direction of the mounting plate 5 is parallel to the axial direction of the grinding wheel 3 and is used to adjust the horizontal distance between the die repairing member and the grinding wheel 3, that is, it can drive the lifting assembly to reciprocate horizontally as a whole to adjust the horizontal distance between the die repairing member and the grinding wheel 3.

[0033] Embodiment 2

[0034] Referring to Figures 1-5 As shown, on the basis of the technical solution of Embodiment 1, for the specific structural design of the lifting assembly, such as Figures 1-3As shown in the figure, the lifting assembly includes a servo electric cylinder 6 fixed to the end of the mounting plate 5. The die repair part is installed at the axis center of the servo electric cylinder 6, and the servo electric cylinder 6 pushes the die repair part to move linearly up and down. The servo electric cylinder 6 is a modular product with an integrated design of a servo motor 10 and a lead screw. It converts the rotary motion of the servo motor 10 into a linear motion. At the same time, it transforms the best advantages of the servo motor 10 - precise rotational speed control, precise revolution control, and precise torque control - into precise speed control, precise position control, and precise thrust control, achieving high-precision linear motion. It has the characteristics of low cost and flexible configuration, and is the best substitute for hydraulic cylinders and pneumatic cylinders. Since the servo electric cylinder 6 is a common modular product on the market, only need to directly purchase it from the market according to the usage parameters and other requirements during actual use, and its specific structural design will not be elaborated here.

[0035] Embodiment 3

[0036] Refer to Figures 1-5 As shown in the figure, on the basis of the technical solution of Embodiment 1, an automatic milling wheel device applied to a grinding machine. For the specific structural design of the horizontal reciprocating displacement mechanism, as Figures 1-3 shown in the figure, the crank-slider 17 assembly includes a connecting shaft 7. One end of the connecting shaft 7 is rotatably connected to the mounting plate 5, and the other end of the connecting shaft 7 is rotatably connected to the end of a rocker 13. The rocker 13 is driven to rotate after the speed of the servo motor 10 is reduced, that is, both ends of the connecting shaft 7 can deflect within a certain angle range. Specifically, end rod bearings 8 and connecting seat bearings 15 are respectively fixed at both ends of the connecting shaft 7. The end rod bearing 8 and the bushing 9 are fixed to the mounting plate 5 together, and the connecting seat bearing 15 and the fixing sleeve 14 are fixed to one end of the rocker 13 together, meeting the operation requirement of being rotatable through the bearings. Further, the end rod bearing 8 and the connecting seat bearing 15 are respectively connected to both ends of the connecting shaft 7 by threads. In addition, the mounting plate 5 is fixed to the slider 17, and the slider 17 is slidably arranged on the linear slide rail 16. The linear slide rail 16 is fixed to the main shaft support plate 1. In this way, the mounting plate 5 can achieve a sliding setting with the main shaft support plate 1. The length direction of the linear slide rail 16 is parallel to the axial direction of the grinding wheel 3, which is convenient for the positioning of the installation operation and leaves enough installation space.

[0037] In this way, when the rocker 13 rotates, it can drive the connecting shaft 7 to reciprocate and swing. Limited by the movement direction of the mounting plate 5, which can only move linearly along the linear slide rail 16, the connecting shaft 7 pushes the mounting plate 5 to move linearly back and forth.

[0038] The horizontal reciprocating displacement mechanism is driven by a servo motor 10. Specifically, a fixed frame 12 is provided on the main shaft support plate 1, and a servo motor 10 and a speed reducer 11 are installed on the fixed frame 12. The speed reducer 11 is connected to a rocker 13 through an output shaft. Generally, the speed reducer 11 is a gear meshing transmission component, and the output shaft and one end of the rocker 13 are fixedly connected, so as to drive the other end of the rocker 13 to rotate around the output shaft. Since there are two slide rails under the mounting plate 5 and they are connected by four sliders 17, the connecting shaft 7 cannot be arranged in the space under the mounting plate 5 due to its own yaw movement and can only be arranged above the mounting plate 5. In this way, although the rocker 13 is suspended at a certain height from the mounting plate 5, there are still certain limitations for the installation space of the speed reducer 11. Therefore, the speed reducer 11 can only be suspended through the fixed frame 12, and the servo motor 10 is fixed at the end of the speed reducer 11.

[0039] Finally, the die repair part is a diamond pen 4, with wear-resistant material and high die repair stability.

[0040] Working principle: The diamond pen 4 is controlled by the cooperation of the servo electric cylinder 6 and the servo motor 10, so that the diamond pen 4 can move longitudinally and horizontally, thereby realizing the automatic dressing of the grinding wheel 3. The servo electric cylinder 6 controls the lifting action of the diamond pen 4. Since the servo electric cylinder 6 is integrally fixed on the mounting plate 5, and the horizontal reciprocating movement of the mounting plate 5 is realized by driving the crank-slider 17 assembly after the servo motor 10 reduces the speed, the longitudinal and horizontal movements of the diamond pen 4 can be completed through the linkage of the above mechanism, generally controlled by a controller. The controller is communicatively connected to the servo electric cylinder 6 and the servo motor 10, and cooperates with corresponding sensors and other conventional components. The specific programming and control principles are not elaborated here.

[0041] In the device of the present utility model, the assembly and cooperation relationships of various components are involved. The servo electric cylinder 6, the servo motor 10, the speed reducer 11, the bearings and the controller, etc. are existing technologies or materials. Those skilled in the art can directly purchase or customize them according to the required product models and specifications.

[0042] The electrical components mentioned in the text are all electrically connected to an external main controller and 220V mains or industrial electricity, and the main controller can be a conventional known device such as a computer that plays a control role.

[0043] The above are only the preferred specific embodiments of the present utility model. Common knowledge such as the specific structures and characteristics known in the solutions is not described in detail herein. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. Any person skilled in the technical field, within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
