[0024] Debris collection function: Through the design of the collection cylinder, it is possible to effectively collect the debris generated by the wear at the contact position between the diamond pen and the grinding wheel body during the dressing process of the grinding wheel body. This not only facilitates the subsequent cleaning work but also helps to keep the working environment clean and reduces the potential hazards of debris to the equipment and operators.

[0026] Shock absorption and stability: Through the design of the rotating ring and rotating cavity between the pressing cylinder and the collection cylinder, the torsional force generated during the extrusion or reset process of the spring can be released. This design not only helps to reduce the stress concentration of the spring but also prevents the spring from bending in the inner cavity during the reset rotation, thereby reducing the reduction of the spring elastic coefficient, increasing the service life of the spring, and at the same time improving the stability and seismic performance of the entire device.

[0027] Simplify the operation process: Due to the automatic reset function of the collection cylinder, the operator does not need to manually perform the reset operation, simplifying the operation process and improving work efficiency.

[0028] Improve dressing accuracy: By precisely controlling the position and attitude of the grinding wheel body and the contact between the diamond pen and the grinding wheel body, this device can achieve high-precision dressing of the grinding wheel body, which is crucial for improving the quality and precision of machined parts.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0039] The present utility model provides a grinding wheel dressing device as Figures 1-6 shown, including a frame 16, an X-axis column slide 17 disposed at the upper side position of the frame 16, and a Y-axis slide 18;

[0040] A Z-axis slide 19 is disposed at the upper side position of the X-axis column slide 17, a C-axis slide 21 is disposed at the lower end position of the Z-axis slide 19, a spindle motor 22 is disposed at the lower side position of the C-axis slide 21, and a grinding wheel body 23 is coaxially connected to one end position of the spindle motor 22;

[0043] A fixed block 4 is disposed at the middle position of the upper side of the tailstock 1, a diamond pen 5 is disposed at the right side position of the fixed block 4, and a workpiece probe 6 is disposed at the upper right side position of the tailstock 1;

[0044] A workpiece body 24 is disposed at the intermediate connection position between the workpiece probe 6 and the A-axis motor 20, and the frame 16 is powered by connecting to an external power supply;

[0045] A collecting cylinder 8 is arranged at the outer side position of the diamond pen 5, and a resisting ring 7 is arranged at the outer position on the right side of the collecting cylinder 8;

[0046] An inner cavity 14 is formed at the connecting position between the inner sides of the collecting cylinder 8 and the fixing block 4. A resisting cylinder 9 is connected to the left side inside the collecting cylinder 8. A connecting plate 10 is arranged at the left side position of the resisting cylinder 9. A spring 11 is connected to the left side of the connecting plate 10. The spring 11 and the inner cavity 14 are internally connected to a fixing plate 15.

[0047] In this embodiment, the working principle of the grinding wheel dressing device is based on multi-axis linkage and high-precision drive technology. By precisely controlling the position and posture of the grinding wheel, efficient dressing of the grinding wheel is achieved. The usage steps are as follows:

[0048] Preparation work: First, fix the grinding wheel body 23 on the main shaft motor 22 and adjust its position through the C-axis slide 21. At the same time, clamp and fix the workpiece body 24 on the Y-axis slide 18 through the workpiece probe 6 and the A-axis motor 20.

[0049] Positioning and adjustment: Utilize the X-axis column slide 17, Y-axis slide 18 and Z-axis slide 19 to adjust the relative positions of the grinding wheel body 23 and the workpiece body 24 to ensure that the grinding wheel can accurately contact the workpiece.

[0050] Dressing operation: Start the main shaft motor 22 to make the grinding wheel body 23 start to rotate. Through the coordinated action of the A-axis motor 20 and the C-axis slide 21, control the diamond pen 5 to contact the rotating grinding wheel body 23 for dressing operation. During this process, the debris generated by the wear at the contact position between the diamond pen 5 and the grinding wheel body 23 will be collected by the collecting cylinder 8.

[0051] Debris collection: During the dressing process, the collecting cylinder 8 contacts the grinding wheel body 23 through the resisting ring 7. As the dressing process progresses, the collecting cylinder 8 is compressed inward, and the resisting cylinder 9 squeezes the spring 11, enabling the collecting cylinder 8 to move in the inner cavity 14, thereby effectively collecting the debris.

[0052] Reset and protection: After the dressing is completed, disconnect the grinding wheel body 23 from the diamond pen 5. The collecting cylinder 8 is reset through the spring 11 in the inner cavity 14 to protect the diamond pen 5 from damage.

[0053] Inspection and adjustment: Use the grinding wheel probe 25 to inspect the dressed grinding wheel to ensure that its size and shape meet the processing requirements. If necessary, repeat the above dressing steps until the grinding wheel reaches the ideal state.

[0054] End work: After completing the dressing of the grinding wheel, turn off all motors, clean the working area, and prepare for the next process.

[0055] The design of this device aims to achieve the functions of online dressing and measuring the grinding wheel body 23. Through high-precision multi-axis linkage control, the dressing efficiency and precision of the grinding wheel body 23 are improved, and at the same time, the service life of the grinding wheel body 23 is extended.

[0056] As Figures 1-4 shown, the diamond pen 5 is connected to the tailstock 1 by a bolt connection method, and the collection cylinder 8 is connected to the tailstock 1 by a nested connection method. The collection cylinder 8 can move in the inner cavity 14. A rotating cavity 12 is provided at the inner connection position between the collection cylinder 8 and the abutting cylinder 9. A rotating ring 13 is provided at the connection position between the abutting cylinder 9 and the rotating cavity 12. The rotating ring 13 is connected to the rotating cavity 12 by a nested connection method, and the rotating ring 13 can rotate in the rotating cavity 12. The rotating ring 13 is connected to the abutting cylinder 9 by an integrated connection method. The abutting cylinder 9 is connected to the inner cavity 14 by an embedded connection method, and the abutting cylinder 9 can move in the inner cavity 14. The spring 11 is connected to the connecting plate 10 by a bolt connection method and is connected to the fixing plate 15 by an integrated connection method. The fixing plate 15 is connected to the inner cavity 14 by a threaded connection method, and the fixing plate 15 can rotate out from the rear end on the left side of the fixing block 4. The workpiece main body 24 is clamped and fixed by the workpiece probe 6 and the A-axis motor 20. The workpiece main body 24 can rotate between the workpiece probe 6 and the A-axis motor 20. The tailstock 1 can move left and right on the Y-axis slide 18. The Z-axis slide 19 can move up and down on the X-axis column slide 17. The spindle motor 22 can rotate on the C-axis slide 21.

[0057] Preferably, after the operator fixes the grinding wheel body 23 on the dressing equipment through this device, the abutting ring 7 can contact the pressed grinding wheel body 23. By compressing the collection cylinder 8 towards the inside of the tailstock 1 and using the abutting cylinder 9 to squeeze the spring 11, it can move in the inner cavity 14. At this time, the abutting ring 7 covers the internal space where the grinding wheel body 23 contacts the diamond pen 5. When the grinding wheel body 23 rotates on the spindle motor 22 and cooperates with the diamond pen 5 for dressing operations, the debris generated by the wear at the contact position between the diamond pen 5 and the grinding wheel body 23 will sputter in the collection cylinder 8. These debris can be collected through the collection cylinder 8, which is convenient for later cleaning. When the grinding wheel body is dressed and disconnected from the diamond pen 5, the collection cylinder 8 is reset by the spring 11 in the inner cavity 14, and the abutting cylinder 9 is pressed to reset the collection cylinder 8, which plays a role in protecting the diamond pen 5 when the diamond pen 5 is not in use.

[0058] Through the settings of the rotating ring 13 and the rotating cavity 12 between the abutting cylinder 9 and the collection cylinder 8, the torsional force generated during the extrusion or reset of the spring 11 is released in the rotating cavity 12. Through the settings of the rotating ring 13 and the rotating cavity 12, it can also prevent the spring 11 from bending in the inner cavity 14 while the spring 11 is rotating during reset, further reducing the decrease in the spring constant of the spring 11 and increasing the service life of the spring 11.

[0059] Finally, it should be noted that the above are only preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
