Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Example:

[0020] As shown in Figures 1 and 2, this utility model provides a servo buffer mechanism for a contour grinding machine.

[0021] It includes a base 1, a head box 2, a left chuck 3, a right chuck 4, a template 5, a clamping cylinder 6, a grinding head frame 7, a grinding edge positioning seat 8, a grinding edge ruler 9, a grinding edge mounting seat 10, a cylinder 11, a pressure regulating valve 12, a buffer mounting seat 13, a grinding wheel cover 14, a contour positioning seat 15, a positioning slide 16, a guide wheel 17, a grinding wheel 18, and a servo buffer mechanism;

[0022] The headstock 2 is mounted on the base 1. The left chuck 3 and the template 5 are mounted on the left shaft inside the headstock 2. The right chuck 4 is mounted on the right shaft inside the headstock 2. The clamping cylinder 6 pushes the right shaft to clamp the product with the left chuck 3 and the right chuck 4. The grinding head frame 7 is mounted on the base 1. The cylinder pushes the grinding head frame 7 to move back and forth. The pressure regulating valve 12 is connected to the cylinder air circuit to control the cylinder feed pressure, thereby controlling the grinding pressure. The edge grinding positioning seat 8 is mounted on the base 1. The grinding edge mounting base 10 is mounted on the side of the grinding head frame 7. The grinding edge scale 9 and the servo buffer mechanism are mounted on the grinding edge mounting base 10 and move together with the grinding head frame 7. The grinding wheel 18 cover 14 is mounted on the grinding head frame 7. The buffer mounting base 13 and the contour positioning base 15 are mounted on the grinding wheel 18 cover 14. The positioning slide 16 forms a sliding fit with the grinding wheel 18 cover 14. The guide wheel 17 is mounted on the positioning slide 16. The grinding wheel 18 is mounted on the grinding wheel 18 shaft inside the grinding head frame 7.

[0023] By clearly defining the layout of each component, a basic framework is provided for the operation of the entire mechanism, ensuring that each component can work together to complete the edge grinding task. The installation position of each component helps to ensure the stability and operating accuracy of the mechanism. For example, the installation position relationship of the head box 2, left chuck 3, right chuck 4 and template 5 can accurately clamp the product and use template 5 for contour edge grinding. The installation position of the grinding head frame 7 and related components provides the correct position and movement trajectory for the grinding action of the grinding wheel 18.

[0024] Optionally, the servo buffer mechanism includes a servo motor 20, a plane bearing 21, a motor base 22, a mounting plate 23, a mounting rod 24, a lead screw 25, a slide block 26, and a push rod 27. The servo motor 20 is mounted on the motor base 22. The plane bearing 21 and the lead screw 25 are mounted on the shaft end of the servo motor 20. The plane bearing 21 is used to bear the grinding force borne by the lead screw 25. The slide block 26 is threadedly engaged with the lead screw 25. The shape of the slide block 26 forms a sliding engagement with the motor base 22. The mounting plate 23 is mounted on the motor base 22. The mounting rod 24 is mounted on the mounting plate 23. The push rod 27 is mounted on the slide block 26 and forms a guiding engagement with the mounting rod 24, moving with the slide block 26.

[0025] The servo motor 20 serves as the power source, bearing the grinding force through the plane bearing 21, ensuring that the lead screw 25 can still rotate stably when subjected to large grinding forces. The threaded engagement between the slide 26 and the lead screw 25, as well as the sliding engagement with the motor base 22, enables the precise movement of the slide 26. The cooperation of the mounting plate 23, mounting rod 24, and push rod 27 provides guidance for the movement of the push rod 27, allowing the push rod 27 to move stably with the slide 26, thereby achieving buffering and positioning functions. This enables precise control of the feed rate and pressure during the grinding process, improving the accuracy and stability of grinding.

[0026] During the grinding process, the contour scale 19 works closely with the servo buffer mechanism to achieve precise control of the feed of the grinding wheel 18. When the cylinder 11 pushes the grinding head frame 7 forward, the grinding wheel 18 contacts the product and begins grinding. The servo buffer mechanism controls the push rod to retract according to the set feed rate. At this time, the contour scale 19, push rod 27, slide 26, guide wheel 17 and other components retract at the same rate, while the grinding wheel 18 advances forward at the same rate to grind the product.

[0027] Optionally, the edge grinding mounting base 10 is mounted on the side of the grinding head frame 7, and the edge grinding scale 9 is mounted on the edge grinding mounting base 10 and moves together with the grinding head frame 7 to provide positioning and measurement reference during the edge grinding process. The contouring scale 19 is mounted on the contouring positioning seat 15 through an adjustable connector, specifically a slider and guide rail cooperation structure, where the slider is fixed to the contouring scale 19, the guide rail is mounted on the contouring positioning seat 15, and the slider can slide along the guide rail and be locked in position by a locking device such as a bolt. The contouring scale 19 can be adjusted in position along its installation direction to adapt to different grinding requirements and moves together with the grinding head frame 7.

[0028] The grinding mounting base 10 is installed on the side of the grinding head frame 7, and the grinding scale 9 is installed on it and moves with the grinding head frame 7. This allows the grinding scale 9 to maintain a relatively fixed position with the grinding part during the grinding process, providing an accurate positioning and measurement benchmark for the grinding operation. Operators can accurately control the grinding size and position according to the indication of the grinding scale 9, thereby improving the accuracy and quality of the grinding.

[0029] Optionally, the grinding wheel 18 cover 14 is mounted on the grinding head frame 7, the buffer mounting seat 13 and the contour positioning seat 15 are mounted on the grinding wheel 18 cover 14, the positioning slide 2616 forms a sliding fit with the grinding wheel 18 cover 14, and the guide wheel 17 is mounted on the positioning slide 2616 for positioning and guiding the product during the edge grinding process.

[0030] The grinding wheel 18 cover 14 is mounted on the grinding head frame 7. The buffer mounting seat 13 and the contour positioning seat 15 are mounted on the grinding wheel 18 cover 14. The positioning slide 2616 is slidably engaged with the grinding wheel 18 cover 14. The guide wheel 17 is mounted on the positioning slide 2616, so that the guide wheel 17 can position and guide the product during the edge grinding process. The guide wheel 17 contacts the product and slides with the movement of the product, ensuring that the product is always in the correct position during the edge grinding process, preventing the product from running away, and improving the stability and accuracy of the edge grinding.

[0031] Optionally, the pressure regulating valve 12 is connected to the cylinder air circuit. By adjusting the pressure regulating valve 12, the cylinder feed pressure is controlled, thereby controlling the grinding pressure to adapt to different grinding requirements.

[0032] The pressure regulating valve 12 is connected to the cylinder air circuit. By adjusting the pressure regulating valve 12, the feed pressure of the cylinder can be controlled, thereby controlling the grinding pressure. This allows the grinding pressure to be adjusted according to different grinding requirements. For example, for products of different materials and hardness, the appropriate grinding pressure can be obtained by adjusting the pressure regulating valve 12, avoiding the impact of excessive or insufficient pressure on grinding quality, and improving the adaptability of the mechanism and the grinding effect.

[0033] Optionally, the push rod 27 is mounted on the slide block 26 and forms a guiding engagement with the mounting rod 24. It moves with the slide block 26. When the servo motor 20 drives the lead screw 25 to rotate, the slide block 26 moves along the lead screw 25, which in turn drives the push rod 27 to move, thereby achieving buffering and positioning functions.

[0034] The push rod 27 is mounted on the slide 26 and forms a guiding engagement with the mounting rod 24. It moves with the slide 26. When the servo motor 20 drives the lead screw 25 to rotate, the slide 26 moves along the lead screw 25, which in turn moves the push rod 27, realizing the buffering and positioning functions. This allows the movement of the push rod 27 to be precisely controlled, thereby achieving buffering and positioning of the grinding process. During the grinding process, the push rod 27 can be adjusted as needed to buffer the feed of the grinding wheel 18, preventing the grinding wheel 18 from directly impacting the product. At the same time, it can also ensure that the grinding wheel 18 grinds in the correct position, improving the quality and stability of the grinding.

[0035] In this application, the servo motor 20 serves as the core power source. By driving the lead screw 25 to rotate, the slide 26, which is threadedly engaged with the lead screw 25, moves along the lead screw 25. The movement of the slide 26 drives the push rod 27 to move. Under the guidance of the mounting rod 24, the push rod 27 achieves precise buffering and positioning functions. At the same time, the cylinder pushes the grinding head frame 7 to move back and forth, driving the grinding wheel 18 to perform grinding. The pressure regulating valve 12 controls the cylinder feed pressure, thereby controlling the grinding pressure. During the edge grinding process, the guide wheel 17 positions and guides the product, and the edge grinding scale 9 provides positioning and measurement references. All components cooperate with each other to complete the edge grinding task of the product.

[0036] In the process of using this application, the product to be ground is first placed between the left chuck 3 and the right chuck 4. The clamping cylinder 6 is then activated, pushing the right shaft to clamp the product between the left chuck 3 and the right chuck 4, ensuring that the product will not loosen during the grinding process. Based on the product's material and grinding requirements, the pressure regulating valve 12 is adjusted to set a suitable cylinder feed pressure, thereby determining the grinding pressure. Simultaneously, according to the grinding dimensions and position requirements, the position of the grinding scale 9 is adjusted to provide an accurate positioning and measurement reference for the grinding operation. The servo motor 20 is then activated, driving the lead screw 25 to rotate. The slide 26 moves along the lead screw 25, moving the push rod 27 to a suitable position for buffering and positioning. Simultaneously, the cylinder pushes the grinding head frame 7 forward, causing the grinding wheel 18 to approach the product. Driven by the motor, the grinding wheel 18 rotates at high speed, beginning to grind the edge of the product. During the grinding process, the grinding wheel 17 contacts the product and slides as the product moves, positioning and guiding the product to prevent it from shifting. The grinding edge scale 9 provides a positioning and measurement reference for the grinding operation. The operator can adjust the grinding parameters in real time according to the indication of the grinding edge scale 9 to ensure the accuracy of the grinding dimensions and position. When the product grinding meets the requirements, the servo motor 20 and the grinding wheel 18 motor are turned off. The cylinder drives the grinding head frame 7 to move backward, moving the grinding wheel 18 away from the product. The clamping cylinder 6 releases the right shaft, and the ground product is removed.

[0037] This application uses a servo buffer system for control, which can precisely control the feed rate, improve processing efficiency and quality, and make the feed rate match the workpiece axis speed. It can be adjusted according to different product requirements, with diversified parameters. The feed rate of the grinding wheel 18 can be adjusted according to different product characteristics to improve processing efficiency. This application can grind irregular shapes as well as round pieces, realizing multi-purpose use.

[0038] This application connects to the cylinder air circuit via a pressure regulating valve 12, which can precisely control the cylinder feed pressure and thus accurately adjust the grinding pressure. Compared with the traditional cylinder system that directly pushes the grinding wheel 18, causing the grinding wheel 18 to directly impact the glass and resulting in chipping and misalignment, this application can flexibly adjust the grinding pressure according to the material, hardness, and other characteristics of different products, ensuring that the pressure is stable and appropriate during the grinding process. This effectively reduces defects such as glass chipping and misalignment, greatly improves the grinding accuracy and surface quality, and makes the product dimensions more accurate and the surface smoother after grinding.

[0039] In the servo buffer mechanism, the servo motor 20 drives the lead screw 25 to rotate, which in turn drives the slide 26 and the push rod 27 to move precisely. This achieves precise control of the feed amount of the grinding wheel 18, overcoming the problem that the traditional pneumatic drive plus hydraulic buffer mechanism cannot accurately control the feed amount, resulting in inconsistent feed speeds that affect product quality. Precise feed amount control makes the grinding process more stable, ensuring the consistency and accuracy of the grinding edge dimensions and improving the overall quality of the product.

[0040] The push rod 27 in the servo buffer mechanism is mounted on the slide 26 and forms a guiding engagement with the mounting rod 24. It moves with the slide 26. When the servo motor 20 drives the lead screw 25 to rotate, the slide 26 moves along the lead screw 25, driving the push rod 27 to move, thereby achieving buffering and positioning of the grinding process. During the grinding process, the push rod 27 can adjust its position as needed to buffer the feed of the grinding wheel 18, preventing the grinding wheel 18 from directly impacting the product and reducing the instability caused by impact force. At the same time, the guide wheel 17 is mounted on the positioning slide 2616, which forms a sliding engagement with the grinding wheel 18 cover 14. The guide wheel 17 positions and guides the product during the edge grinding process, ensuring that the product is always in the correct position during the edge grinding process, further enhancing the stability of the processing.

[0041] Compared to traditional cam-driven methods, the mechanism structure of this application is relatively simple. Cam-driven equipment has a complex structure, which is not only expensive but also prone to failure and difficult to repair and maintain. In contrast, the servo buffer mechanism of this application achieves precise control of grinding through the reasonable combination of components such as servo motor 20, lead screw 25, and slide 26, which reduces the complexity of the mechanical structure, lowers the probability of failure, improves the reliability and stability of the equipment, and reduces production interruptions and maintenance costs caused by equipment failure.

[0042] The pressure regulating valve 12 can adjust the cylinder feed pressure according to different grinding requirements, thus adapting to the grinding of products of different materials and specifications. Meanwhile, the precise control capability of the servo buffer mechanism allows the equipment to quickly and accurately adjust grinding parameters without the complex debugging and adjustments required by traditional equipment. This flexibility enables the profile grinding machine of this application to adapt to the production needs of various products, improving the equipment's versatility and production efficiency.

[0043] The grinding edge ruler 9 is mounted on the grinding edge mounting base 10 and moves together with the grinding head frame 7, providing an accurate positioning and measurement benchmark for the grinding edge operation. Operators can intuitively perform grinding operations based on the indications of the grinding edge ruler 9, eliminating the need for complex measurements and adjustments. This simplifies the operation process, reduces the skill requirements for operators, and improves production efficiency. Simultaneously, the precise positioning and measurement benchmark also reduces the product defect rate caused by operational errors, further improving production efficiency.

[0044] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
