Technical Field

[0001] This invention belongs to the technical field of aluminum alloy product processing, and in particular relates to an aluminum alloy disc surface polishing device that can automatically clean the base. Background Technology

[0002] Aluminum alloys are classified into wrought aluminum alloys and cast aluminum alloys according to their composition and processing methods. Wrought aluminum alloys are made by first melting and casting the alloy raw materials into ingots, and then performing plastic deformation processing, such as rolling, extrusion, stretching, and forging, to produce various plastically processed products. Cast aluminum alloys are made by melting the raw materials and then directly casting them into blanks of various parts using sand molds, iron molds, investment casting, and die casting methods. Among them are round aluminum alloy raw materials, and their surfaces need to be polished during processing.

[0003] A search revealed a Chinese patent application with publication number CN112338650A, which discloses a batch grinding device for aluminum alloy tubes that can automatically clean the base. This device can grind multiple aluminum alloy tubes simultaneously and can spray air onto the grinding surface during the grinding process to completely remove dust.

[0033] In actual use, the aluminum alloy body 2 is placed on the support plate 3, and then the calibration ring 8 is moved downward by the alignment cylinder 6. The calibration unit set on the calibration ring 8 calibrates the aluminum alloy body 2 to ensure that it is in the center position. After the lower pressure plate 7 contacts the aluminum alloy body 2, it is aligned and limited. The setting of the adjustment unit makes the calibration ring 8 disengage from the aluminum alloy body 2. Then, under the drive of the grinding motor 4, the grinding head 5 performs grinding operations on the side of the aluminum alloy body 2.

A second adjusting block 15 is provided inside the connecting frame 14. The second adjusting block 15 is provided with a second inclined surface 16 that cooperates with the first inclined surface 13. Two symmetrically arranged snap-fit ​​protrusions 17 are fixedly connected to the side of the second adjusting block 15.

A straight snap-fit ​​groove 20 that cooperates with the snap-fit ​​plate 19 is provided on the second inclined surface 16.

[0037] The first adjusting block 12 is fixedly connected to a second connecting plate 21, and a first through groove 22 is provided on the second connecting plate 21. The calibration ring 8 is fixedly connected to a first connecting block 23, and a second through groove 24 is provided on the first connecting block 23 for the second connecting plate 21 to pass through.

[0038] When the above-mentioned adjustment unit is actually used, after the lower pressure plate 7 contacts the upper end of the aluminum alloy body 2, it can drive the first insertion rod 9 to move upward. The movement of the first insertion rod 9 drives the first adjustment block 12 to move upward. The first inclined surface 13 and the second inclined surface 16 are configured to cooperate, as are the snap-fit ​​plate 19 and the straight snap-fit ​​groove 20. Under the limitation of the snap-fit ​​protrusion 17 and the first snap-fit ​​groove 18, the second adjustment block 15 can be driven to move in the horizontal direction, which in turn drives the second connecting plate 21 to move. The first connecting block 23 can pass through the first through groove 22, and the calibration ring 8 can fall into the main housing 1 to complete the center calibration of the aluminum alloy body 2.

A cleaning unit for cleaning up waste chips is provided inside the main housing 1.

[0042] The rotation of the first motor 33 drives the first rotating shaft 34 to rotate, which in turn drives the fifth connecting plate 40, the sixth connecting plate 42, and the first cylinder 41 to rotate. The first cylinder 41 can adjust the position of the grinding motor 4 to adapt to aluminum alloy bodies 2 of different diameters. The setting of the first snap-fit ​​plate 37 and the second snap-fit ​​groove 38 can ensure that the rotation of the first motor 33 does not affect the downward pressing operation of the alignment cylinder 6.

[0043] Combination Figure 2 The cleaning unit includes a cleaning plate 44 sleeved on the outside of the support plate 3. The cleaning plate 44 can rotate around the support plate 3. A second connecting block 45 is fixedly connected to the upper end of the cleaning plate 44. The second connecting block 45 has an insertion hole 46. A sixth connecting plate 42 can be inserted into the insertion hole 46. A groove 47 is provided in the main housing 1. The groove 47 is connected to a moving plate 49 through a plurality of third springs 48 for providing elasticity. The moving plate 49 is fixedly connected to the support plate 3.

The fourth spring 53 is sleeved on the outside of the third insert rod 51. A lower pressing block 54 is fixedly connected to the end of the third insert rod 51. A second curved surface 55 is provided on the lower pressing block 54.

[0045] When the above-mentioned cleaning unit is actually used, the lower pressure plate 7 does not press down to drive the support plate 3 and the moving plate 49 to press down. At this time, the sixth connecting plate 42 is inserted into the second connecting block 45. The rotation of the first motor 33 can drive the cleaning plate 44 to rotate, and clean the impurities generated during the grinding left on the main housing 1 to prevent long-term impurity residue from being difficult to clean. After the lower pressure plate 7 drives the support plate and the moving plate 49 to press down, the sixth connecting plate 42 is disengaged from the second connecting block 45. The first motor 33 can drive the grinding motor 4 to rotate to drive the grinding head 5 to grind the side of the aluminum alloy body 2.

[0046] In summary, the working principle of this invention is as follows: the aluminum alloy body 2 is placed on the support plate 3, and then, driven by the alignment cylinder 6, the calibration ring 8 moves downward. The calibration unit on the calibration ring 8 calibrates the aluminum alloy body 2 to ensure it is in the center position. After the lower pressure plate 7 contacts the aluminum alloy body 2, it is aligned and limited. The setting of the adjustment unit causes the calibration ring 8 to disengage from the aluminum alloy body 2. Then, driven by the grinding motor 4, the grinding head 5 grinds the side of the aluminum alloy body 2. After the lower pressure plate 7 contacts the upper end of the aluminum alloy body 2, it can drive the first insertion rod 9 to move upward. The movement of the first insertion rod 9 drives the first adjusting block 12 to move upward. The first inclined surface 13 and the second inclined surface 16 are configured to cooperate, as are the snap-fit ​​plate 19 and the straight snap-fit ​​groove 20. Under the limitation of the snap-fit ​​protrusion 17 and the first snap-fit ​​groove 18, the second adjusting block 12 can be driven to move upward. When segment 15 moves horizontally, it causes the second connecting plate 21 to move. The first connecting block 23 can pass through the first through slot 22, and the calibration ring 8 can fall into the main housing 1 to complete the center calibration of the aluminum alloy body 2. The lower pressure plate 7 can limit the position of the aluminum alloy body 2. When the lower pressure plate 7 does not press down, it causes the support plate 3 and the moving plate 49 to press down. At this time, the sixth connecting plate 42 is inserted into the second connecting block 45. The rotation of the first motor 33 can drive the cleaning plate 44 to rotate, and clean the impurities generated during the grinding process on the main housing 1 to prevent long-term impurity residue from being difficult to clean. After the lower pressure plate 7 drives the support plate and the moving plate 49 to press down, the sixth connecting plate 42 is disengaged from the second connecting block 45. The first motor 33 can drive the grinding motor 4 to rotate, thereby driving the grinding head 5 to grind the side of the aluminum alloy body 2.
