Description

Technical Field

[0001] This utility model relates to the field of grinding wheel adjustment technology for spherical milling machines, specifically a grinding wheel adjustment and compensation mechanism for milling machines. Background Technology

[0002] A spherical milling machine is a device used for grinding the spherical shape of lenses. As the grinding wheel wears continuously during the processing, the thickness and spherical shape of the product change, and the equipment needs to be adjusted to ensure the processing quality of the product. Traditional milling machines adjust the X and Y positions of the product through the workpiece feeding mechanism to achieve the desired result. This requires adjusting the product's position in both directions simultaneously, which is quite cumbersome. This is especially true when the milling machine is equipped with a robotic arm, which also needs to be adjusted, making the adjustment even more complicated. In view of this, a grinding wheel adjustment and compensation mechanism for milling machines is proposed. Utility Model Content

[0003] To address the problems existing in the prior art, the purpose of this utility model is to provide a grinding wheel adjustment and compensation mechanism for milling machines, which can reduce the adjustment steps and improve adjustment efficiency after the grinding wheel wears.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a grinding wheel adjustment and compensation mechanism for a milling machine, the main body of which is installed on the side of a workpiece adjustment and feeding mechanism and a robotic arm picking and unloading mechanism. The main body includes a rotating tray, an X-axis guide rail is provided on the rotating tray, a servo motor is provided on the side of the X-axis guide rail on the rotating tray, a ball screw is provided on the servo motor, the ball screw is connected to a Y-axis dovetail seat, a Y-axis adjusting screw is provided on the side of the Y-axis dovetail seat, a Z-axis dovetail seat is connected to the Y-axis adjusting screw, a Z-axis adjusting screw is provided on the side of the Z-axis dovetail seat, a grinding wheel box is connected to the Z-axis adjusting screw, and a grinding wheel is provided on the grinding wheel box.

[0005] In some embodiments, an X-axis grating ruler is mounted on the rotating plate below the Y-axis adjusting screw, and the scale bar of the X-axis grating ruler is connected to the Y-axis dovetail seat, and the head of the scale is connected to the rotating plate.

[0006] In some embodiments, a Y-axis optical encoder is mounted on the side of the Z-axis dovetail mount near the servo motor, and the scale bar of the Y-axis optical encoder is connected to the Z-axis dovetail mount, while the head portion is connected to the Y-axis dovetail mount.

[0007] In some embodiments, the main body, the workpiece adjustment and feeding mechanism, and the robotic arm picking and unloading mechanism are all mounted on a base, and an intelligent control system is provided on the base, which controls the operation of the main body, the workpiece adjustment and feeding mechanism, and the robotic arm picking and unloading mechanism. In some embodiments, a hand crank is provided on the base, and the hand crank controls the rotation of the rotating tray through gears inside the base.

[0008] In summary, this utility model has the following beneficial effects: This invention uses a servo motor to control the Y-axis dovetail seat, which in turn moves the Z-axis dovetail seat and the grinding wheel together. This allows the worn grinding wheel to actively approach the product. By utilizing the movement of the grinding wheel, when the grinding wheel is in contact with the product, the grinding point of the grinding wheel coincides with the center point of the product's spherical surface. This allows for direct adjustment in one step, eliminating the need for operators to adjust the product position through the workpiece adjustment feed mechanism and the robotic arm's material handling mechanism. This reduces adjustment steps and improves adjustment efficiency. Attached Figure Description

[0014] See Figure 1-5 A grinding wheel adjustment and compensation mechanism for a milling machine is disclosed. The main body 1 is installed on the side of the workpiece adjustment and feeding mechanism 2 and the robotic arm loading and unloading mechanism 3. The main body 1 includes a rotating pallet 11, an X-axis guide rail 12 is provided on the rotating pallet 11, a servo motor 17 is provided on the side of the X-axis guide rail 12 on the rotating pallet 11, a ball screw is provided on the servo motor 17, the ball screw is connected to a Y-axis dovetail seat 13, a Y-axis adjusting screw 14 is provided on the side of the Y-axis dovetail seat 13, a Z-axis dovetail seat 15 is connected to the Y-axis adjusting screw 14, a Z-axis adjusting screw 16 is provided on the side of the Z-axis dovetail seat 15, a grinding wheel box 18 is connected to the Z-axis adjusting screw 16, and a grinding wheel 19 is provided on the grinding wheel box 18.

[0015] In some embodiments, an X-axis grating ruler 110 is mounted on the rotating tray 11 below the Y-axis adjusting screw 14, and the ruler strip of the X-axis grating ruler 110 is connected to the Y-axis dovetail seat 13, and the head of the ruler is connected to the rotating tray 11.

[0016] In some embodiments, a Y-axis grating ruler 111 is mounted on the side of the Z-axis dovetail 15 near the servo motor 17, and the ruler strip of the Y-axis grating ruler 111 is connected to the Z-axis dovetail 15, while the meter head is connected to the Y-axis dovetail 13.

[0017] In some embodiments, the main body 1, the workpiece adjustment and feeding mechanism 2, and the robotic arm picking and unloading mechanism 3 are all mounted on a base, and an intelligent control system is provided on the base. The intelligent control system controls the operation of the main body 1, the workpiece adjustment and feeding mechanism 2, and the robotic arm picking and unloading mechanism 3. In some embodiments, a hand crank is provided on the base, and the hand crank controls the rotation of the rotating tray 11 through the gears inside the base.

[0018] Working principle: During the setup of the automatic spherical milling machine, the operator adjusts the X and Y axes of the workpiece adjustment feed mechanism 2 to make the center point A of the spherical surface of product 4 coincide with the grinding point B of the grinding wheel 19 of the body 1, as shown in the attached diagram. Figure 3 As shown, it can grind out qualified finished products; when the grinding wheel 19 wears, the grinding point B of the grinding wheel 19 will change and will no longer coincide with the center point A of the spherical surface of product 4, as shown in the attached figure. Figure 4 As shown, this causes changes in the spherical shape and thickness of product 4, affecting the processing of product 4. At this time, the operator can input the compensation value of grinding wheel 19 into the intelligent control system. Subsequently, the intelligent control system will control the servo motor 17 on the main body 1 to work. The intelligent control system is a control system set by the existing intelligent program, which will not be described in detail here. The servo motor 17 drives the Y-axis dovetail seat 13 to move through the ball screw. Then, the Y-axis dovetail seat 13 drives the grinding wheel box 18 on the Z-axis dovetail seat 15 to move towards product 4 along the X-axis guide rail 12. Since the connection between the existing grinding wheel 19 and the grinding wheel box 18 is movable, when the grinding wheel 19 touches product 4, it will automatically change direction when it gets close to product 4, so that the grinding point B of the grinding wheel 19 coincides with the spherical center point A of product 4, as shown in the attached figure. Figure 5 As shown, this achieves feed compensation, eliminating the need for operators to adjust the workpiece adjustment feed mechanism 2 to adjust the position of product 4, and also eliminating the need to adjust the picking and placing position of the robot arm in the robot arm picking and placing mechanism 3. The adjustment is completed in one go. During adjustment, both the X-axis grating ruler 110 and the Y-axis grating ruler 111 can display the adjustment distance synchronously, making the movement position of the grinding wheel 19 more accurate for the operator during adjustment, and making equipment adjustment more convenient and faster. As attached Figure 2As shown, if a larger grinding wheel 19 is replaced, the position of the grinding point B of the grinding wheel 19 will change. At this time, the operator controls the Y-axis adjusting screw 14 to rotate, and then the Y-axis adjusting screw 14 drives the Z-axis dovetail seat 15 to move back and forth on the Y-axis dovetail seat 13, so that the grinding wheel 19 can move forward or backward, ensuring that the grinding point B of the grinding wheel 19 coincides with the spherical center A of the product 4. The operator does not need to adjust the product 4 itself through the workpiece adjustment feed mechanism 2 and the robot arm loading and unloading mechanism 3, reducing operation steps and improving adjustment efficiency. If the grinding point B of the grinding wheel 19 is not at the same height as the center point A of the spherical surface of the product 4, the operator can control the Z-axis adjusting screw 16 to move the grinding wheel box 18. The connection between the Z-axis dovetail seat 15 and the grinding wheel box 18 is designed to be inclined. Therefore, when the Z-axis adjusting screw 16 adjusts the movement of the grinding wheel box 18, the grinding wheel box 18 will move on the inclined surface, thereby realizing the adjustment of the height of the grinding wheel box 18. This structure is the existing structure and will not be described in detail here.
