Abstract
Description
Technical Field
[0001] This application relates to the field of machining technology, and in particular to an automatic grinding device for the surface shape of parts. Background Technology
[0002] Manual scraping is a precision machining process that uses hand tools (scrapers) to perform micro-cutting on metal surfaces. It is a core technology for achieving flatness and straightness in machine tool guides, precision instruments, and high-precision mechanical components. Its principle is to gradually eliminate microscopic unevenness on the workpiece surface through repeated scraping and color-coding inspection, ultimately achieving micron-level or even sub-micron-level precision.
[0003] However, scraping techniques rely heavily on skilled workers and are extremely costly in terms of labor. Currently, the flatness or straightness of the part to be polished is typically checked using equipment such as laser collimators and coordinate measuring machines, and then repeatedly scraped manually based on the flatness information. While the equipment improves inspection efficiency, the scraping process still requires manual operation, resulting in limited overall efficiency gains. Utility Model Content

[0025] To illustrate the technical solutions described in this application, specific embodiments are provided below, showing only the parts related to the embodiments of this application.
[0026] The automatic surface grinding device for parts disclosed in this application can be applied to applications such as machine tool guideways and precision instruments that require precision machining and grinding. This device can be used to detect the flatness of part surfaces and then grind the parts based on the flatness information. This achieves automated grinding of parts, thereby saving labor costs and improving production efficiency.
[0027] The automatic surface grinding device for parts disclosed in this application can be located above the part and can grind the upper surface of the part. It should be noted that the upper surface of the part can refer to the side facing the automatic surface grinding device, which can be understood as the side of the part that needs to be ground. Therefore, if other surfaces of the part need to be ground, the part can be adjusted so that the side to be ground faces the automatic surface grinding device. This application does not impose any limitations on the shape of the part or its upper surface.
[0028] like Figures 1 to 4 As shown, this application provides an automatic grinding device 1 for the surface shape of a part, a measuring module 10, a grinding module 20, and a first guide rail 30 and a second guide rail 40 disposed opposite to each other on both sides of the part 2.
[0029] In some embodiments, the measuring module 10 may be disposed on the first guide rail 30, and the measuring module 10 may move along the extension direction of the first guide rail 30 on the upper surface of the part 2 and measure the flatness information of the upper surface of the part 2.
[0030] In some embodiments, the grinding module 20 may be disposed on the second guide rail 40, and the grinding module 20 may move along the extension direction of the second guide rail 40 on the upper surface of the part 2, and may grind the upper surface of the part 2 according to the flatness information obtained by the measurement module 10.
[0031] Specifically, such as Figure 1 As shown, the first guide rail 30 and the second guide rail 40 can be arranged in parallel and located above both sides of the part 2. Both the first guide rail 30 and the second guide rail 40 have tracks, along which the measuring module 10 and the grinding module 20 can slide. The tracks of the first guide rail 30 and the second guide rail 40 can be positioned opposite each other, thus allowing the measuring module 10 and the grinding module 20 to be located above the part 2. For ease of description, this application constructs an XYZ coordinate system with the extension directions of the first guide rail 30 and the second guide rail 40 as the X-axis.
[0032] In some other embodiments, the polishing module 20 may also be disposed on the first guide rail 30, that is, the polishing module 20 and the measuring module 10 may be disposed on the same rail.
[0033] In some embodiments, the measurement module 10 may include a first motion module 11, a displacement measurement module 12, and a laser measurement module 13. The first motion module 11 can be used to move the displacement measurement module 12 and the laser measurement module 13 along the upper surface of the part 2. The displacement measurement module 12 can contact the upper surface of the part 2 and obtain flatness information based on the magnitude of the offset. The laser measurement module 13 can obtain flatness information by emitting a laser beam. The laser measurement module 13 can cooperate with the displacement measurement module 12 to detect the flatness of the part 2. That is, obtaining the flatness information of the upper surface of the part 2 requires comprehensive consideration of the flatness information measured by the displacement measurement module 12 and the flatness information measured by the laser measurement module 13.
[0034] In some embodiments, the first motion module 11 may include a first support portion 110 and a first movable portion 111. One end of the first support portion 110 is fixedly connected to the first movable portion 111, and the other end of the first support portion 110 is fixedly connected to the side wall of the displacement measuring module 12. The first movable portion 111 can be slidably disposed in the track of the first guide rail 30, and the displacement measuring module 12 can be disposed on the first support portion 110. Thus, the first motion module 11 can drive the displacement measuring module 12 and the laser measuring module 13 thereon to move along the first guide rail 30. Viewed along the Z-axis, the width of the track of the first guide rail 30 can be smaller than the width of the first support portion 110, but larger than the width of the first movable portion 111.
[0035] In some embodiments, the laser measurement module 13 may include a lens unit 131, a laser unit 132, and a mounting base 133 for fixing the lens unit 131. The mounting base 133 may be disposed on the first support portion 110, and the mounting base 133 may have a groove for accommodating the lens unit 131. The laser unit 132 may be fixedly disposed on the first guide rail 30, and the laser unit 132 may emit a laser beam aimed at the lens unit 131 to obtain flatness information based on the beam reflected by the lens unit 131.
[0036] Specifically, when the first movable part 111 drives the lens unit 131 on the first bearing part 110 to move on the upper surface of the part 2, the laser unit 132 can obtain information such as the height difference and offset of the laser spot based on the beam reflected by the lens unit 131, and then obtain the flatness information of the upper surface of the part 2.
[0037] In some embodiments, the first motion module 11 can drive the lens unit 131 to reciprocate as needed, thereby enabling multiple measurements of the flatness of the part 2 and improving the accuracy of the measurement.
[0038] In some embodiments, the laser measurement module 13 can be a laser interferometer or a laser collimator, and the corresponding lens unit 131 can be a single-sided reflector or a double-sided reflector.
[0039] In some embodiments, the displacement measuring module 12 may include a displacement component 121 and a displacement contact 122. The displacement component 121 may be disposed on the first support portion 110, and the displacement contact 122 may be connected to the displacement component 121 and abut against the upper surface of the part 2. The displacement component 121 may have a built-in grating component (not shown) and a reading component (not shown). Specifically, when the first motion module 11 drives the displacement measuring module 12 to move on the upper surface of the part 2, the displacement contact 122 will generate a displacement along the Z-axis. At this time, the built-in grating component can move with the displacement contact 122, and the reading component disposed opposite to the grating component can read the displacement of the grating component, thereby obtaining the flatness information of the upper surface of the part 2.
[0040] In summary, when the first motion module 11 moves along the first guide rail 30, the displacement measurement module 12 and the laser measurement module 13 can simultaneously measure the flatness of the upper surface of the part 2 and obtain the flatness information of the upper surface of the part 2. The flatness information obtained by the automatic surface grinding device 1 of this application requires the integration of the flatness information measured by the displacement measurement module 12 and the laser measurement module 13.
[0041] In some embodiments, the grinding module 20 may include an inclination measurement module 21, a second motion module 22, a grinding wheel 23, and a moving module 24. The second motion module 22 may be used to drive the inclination measurement module 21, the moving module 24, and the grinding wheel 23 to move along the upper surface of the part 2. The inclination measurement module 21 may be used to obtain the inclination angle of the grinding wheel 23. The moving module 24 may be used to drive the grinding wheel 23 closer to or away from the upper surface of the part 2 and drive the grinding wheel 23 to rotate.
[0042] In some embodiments, the second motion module 22 may include a second support portion 220 and a second movable portion 221. One end of the second support portion 220 may be fixedly connected to the second movable portion 221, and the other end of the second support portion 220 may be fixedly connected to the side wall of the moving module 24. The second movable portion 221 may be slidably disposed in the track of the second guide rail 40. The moving module 24 may be disposed on the second support portion 220, and the tilt measuring module 21 and the grinding wheel 23 may be disposed on the moving module 24.
[0043] In some embodiments, the second motion module 22 can control the tilt angle of the grinding wheel 23. Specifically, the second movable part 221 can swing up and down, causing the tilt measuring module 21, the moving module 24, and the grinding wheel 23 to swing together, thereby changing the tilt angle of the grinding wheel 23. This allows adjustment of the grinding angle of the grinding wheel 23 on the part 2, thereby improving the precision of the machining and grinding. Specifically, as... Figure 1 and Figure 4As shown, the upper or lower end of the second movable part 221 can swing back and forth along the r-axis, driving the grinding wheel 23 to swing together along the r-axis.
[0044] In some embodiments, the moving module 24 can drive the grinding wheel 23 to move up and down and rotate the grinding wheel 23 for grinding. Specifically, the moving module 24 can move up and down along the Z-axis as needed, thereby driving the grinding wheel 23 to move synchronously along the Z-axis. When the grinding wheel 23 moves to a predetermined position, it can be driven to rotate to grind the upper surface of the part 2.
[0045] In some embodiments, the mobile module 24 may include a rotating shaft 240 for connection to the axis of the grinding wheel 23. The rotating shaft 240 may be driven to rotate by a servo motor built into the mobile module 24, thereby causing the grinding wheel 23 to rotate.
[0046] In some embodiments, the tilt measuring module 21 can be disposed above and connected to the moving module 24. The tilt measuring module 21 can be used to obtain the tilt angle of the grinding wheel 23. Specifically, the tilt measuring module 21 can obtain the tilt angle of the grinding wheel 23 by measuring the verticality of the moving module 24. When the second motion module 22 moves along the second guide rail 40, this mechanical movement causes the grinding wheel 23 to tilt unpredictably, affecting the grinding effect. The tilt measuring module 21 can obtain multiple tilt angles generated by the grinding wheel 23 during movement. The moving module 24 can swing accordingly based on the multiple tilt angles measured by the tilt measuring module 21, thereby correcting the tilt angle of the grinding wheel 23 or adjusting the tilt angle according to the actual grinding angle required by the grinding wheel 23. Thus, the grinding wheel 23 can maintain the correct grinding wheel 23 angle during movement, for example, preventing the grinding wheel 23 from turning to the side towards the first guide rail 30 or the second guide rail 40, thereby improving the accuracy of the grinding wheel 23 during grinding.
[0047] In some embodiments, the grinding module 20 may further include a dust removal module 25 and a dust collection module 26, both of which are disposed on the moving module 24. The dust removal module 25 may be located in front of the bottom end of the grinding wheel 23, and the dust collection module 26 may be located behind the bottom end of the grinding wheel 23. Specifically, the dust removal module 25, the dust collection module 26, and the grinding wheel 23 can move along the second guide rail 40. When the grinding wheel 23 moves to the corresponding area on the upper surface of the part 2 to begin grinding, since grinding will generate debris or cutting waste, the dust removal module 25 can be used to blow away the debris, and the dust collection module 26 can be used to absorb and collect the debris. In this case, by combining blowing and suction, the flying of debris can be effectively controlled, and the debris can be properly collected, thereby improving the safety of the entire workflow.
[0048] In some embodiments, the automatic surface grinding device 1 for parts may include a main control module (not shown in the figure), which may be communicatively connected to the measurement module 10 and the grinding module 20.
[0049] Specifically, the main control module can control the measurement module 10 to measure the upper surface of part 2 to obtain flatness information. The measurement module 10 can send the flatness information measured by the displacement measurement module 12 and the flatness information measured by the laser measurement module 13 to the main control module. The main control module can integrate the two flatness information to finally obtain the flatness information of the upper surface of part 2.
[0050] In some embodiments, the main control module can control the grinding module 20 to grind the upper surface of part 2 based on the flatness information of the upper surface of part 2. Further, the grinding module 20 can pre-move along the upper surface of part 2, and the tilt measurement module 21 of the grinding module 20 can acquire the offset along the rotation axis direction generated during its movement, or it can acquire the tilt angle of the grinding wheel 23. Subsequently, during the grinding process, the moving module 24 of the grinding module 20 can correct the grinding wheel 23. This further improves the grinding accuracy.
[0051] In some embodiments, after the grinding module 20 grinds the upper surface of part 2, the measuring module 10 can measure the flatness of the upper surface of part 2. The grinding module 20 then grinds the upper surface of part 2 again. That is, the measuring module 10 and the grinding module 20 can work alternately multiple times until the entire grinding process is completed. This enables automated grinding of part 2, improving grinding efficiency while ensuring a certain grinding accuracy.
[0052] In this application, the measuring module 10 and the grinding module 20 are respectively positioned on two guide rails on both sides of the part. After the measuring module 10 acquires the flatness information of the part 2, the grinding module 20 grinds the part 2 based on the flatness information obtained by the measuring module 10. In this configuration, the tightness of the fit between the measuring module 10 and the grinding module 20 can be improved, automating both the measuring and grinding processes of the part 2. This saves a significant amount of labor costs while improving production efficiency while maintaining a certain level of accuracy.

Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this application. Furthermore, under the teachings of this application, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this application.
