For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0049] It should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0050] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0051] Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. In case of any conflict, the definitions in this specification shall prevail.

[0052] This utility model is a grinding wheel dressing tool that integrates high-precision adjustment and flipping functions, aiming to improve the accuracy and efficiency of grinding wheel dressing.

[0053] Besides allowing for convenient fine-tuning of the diamond dressing tool's feed, this invention also allows users to flip the dressing device via a flipping mechanism to create machining space, eliminating the need for frequent disassembly and reassembly of the dressing device. This improves work efficiency and meets various machining needs. Using the fine-tuning feed mechanism, users can precisely control the feed rate of the dressing tool. This helps ensure the stability and accuracy of the dressing process, avoiding over-dressing or under-dressing. After adjusting the feed rate, the dressing device is activated, and the dressing tool begins dressing the grinding wheel. During the dressing process, users can adjust the feed rate as needed to achieve the best dressing effect.

[0054] This invention is suitable for various applications requiring high-precision grinding wheel dressing, such as precision machining, mold manufacturing, and automotive parts manufacturing. In these fields, the precision and shape requirements for grinding wheels are extremely high, thus necessitating the use of high-quality dressing devices to ensure processing quality and efficiency.

[0055] This utility model includes: a sleeve 1, an end cap 2, a rotating plate 3, a base 4, a bottom plate 5, a pen shaft 6, a screw 7, and a scale wheel 8.

[0056] The present invention will be further described below with reference to the accompanying drawings and embodiments.

The knob 8001 is connected to the conical wheel 8002 through a neck ring groove 8003. The wheel axle hole 8004 is axially formed in the middle of the knob 8001, the neck ring groove 8003, and the conical wheel 8002. The wheel conical hole 8006 is formed on the neck ring groove 8003. The conical wheel 8002 is shaped like a cone frustum. A graduated ring 8005 surrounds the outer wall of the conical wheel 8002. Preferably, the circumference of the surface of the conical wheel 8002 is divided into 100 equal divisions, with a graduated ring 8005 being 0.2 mm wide and 0.3 mm deep. The graduated ring 8005 is engraved with several lines on the conical or circumferential surface of the graduated wheel 8 to indicate the angle of rotation of the graduated wheel 8. The axial movement of the pen shaft 6 can be obtained by multiplying the angle of rotation of the graduated wheel 8 by the pitch of the screw 7.

[0071] In this embodiment, the base 4, base plate 5, and clamping screw 11 combine to form a fixed base unit, used to install and fix the entire dressing device, ensuring its stability during operation. The rotating plate 3 and base 4 are fitted together to form a flipping mechanism, allowing the dressing device to flip within a certain range to adapt to different angles of grinding wheel dressing requirements. The sleeve 1, pen shaft 6, screw 7, and graduated wheel 8 form a fine-tuning feed mechanism for the diamond pen 12, allowing precise feed adjustment of the diamond pen dressing tool to ensure accuracy during the dressing process. It allows the user to adjust the feed amount in small increments.

[0072] Preferably, the adjusting pin 14 is a knurled flat head screw (M6×20 / J22-8). The slotted screw 13 is an M10×45 T-bolt.

[0073] In this embodiment of the invention, the sleeve 1 is also equipped with an adjusting pin 14 whose front end extends into the axial guide groove 6003 of the pen shaft 6. The adjusting pin 14 can be used to prevent the pen shaft 6 from rotating when adjusting its axial position. After the pen shaft 6 is adjusted to the correct position, tightening the adjusting pin 14 can lock the pen shaft 6. The end cap 2 is used to position and install the screw 7 and the scale wheel 8.

Upper pin holes 3007 are symmetrically opened in the middle of both sides of the rotating plate 3; correspondingly, lower pin holes 4006 are symmetrically opened at the bottom of both sides of the right end of the base 4. Spring cylindrical pins 9 are inserted into the upper pin holes 3007 and lower pin holes 4006 respectively; a cylindrical helical tension spring is connected between the upper and lower corresponding spring cylindrical pins 9 on the same side. The rotating plate 3 and the base 4 are tightly pulled together to ensure that the left end of the rotating plate 3 is tightly fitted with the positioning screw 10. By adjusting the height of the positioning screw 10, the height of the center of the diamond 12 can be adjusted. By adjusting the hexagonal nut M8 fitted on the positioning screw 10, the adjusted positioning screw 10 can be tightly locked onto the base 4.

[0075] In this embodiment of the present invention, the rear section of the diamond pen 12 is inserted into the pen hole 6005 of the pen shaft 6 from the shaft end interface 6002, and the pen pin 15 is tightened to fix the diamond pen 12 in the pen shaft 6; the middle and rear sections are inserted into the pen hole 6005 of the pen shaft 6 in the sleeve 1, and the front section of the screw 7, namely the threaded rod section 7001, is screwed into it at the same time. The annular rod section 7002 of the screw 7 is blocked inside the end cap 2, which is fastened to the rear end of the sleeve 1. The rear section of the screw 7, namely the pin section 7003, passes through the cover shaft hole 2002 of the end cap 2 and is then inserted into the wheel shaft hole 8004 of the scale wheel 8. After the rod cone hole 7004 and the wheel cone hole 8006 are aligned, they are fastened with a pin. At this point, the adjusting pin 14 is screwed into the adjusting pin hole 1005 at the top of the sleeve and pushed into the shaft guide groove 6003. This ensures that the pen shaft 6 is stably guided and fed back and forth in the sleeve 1 without rotation, and also allows the pen shaft 6 to be positioned in the sleeve 1 when needed. Referring to the scale on the engraving ring 8005, the pen shaft 6 is adjusted to drive the diamond pen 12 to feed by manually operating the knob 8001.

[0076] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this application will not describe the various possible combinations separately. Furthermore, various different embodiments of this application can also be arbitrarily combined, as long as they do not violate the spirit of this application, and they should also be regarded as the content disclosed by this invention.
