[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes an oil cleaning device and a cleaning method for precision parts after processing.

[0036] Embodiment 1:

[0037] See also Figure 1 - Figure 3 , an oil cleaning device, comprising a cleaning chamber 1, an upper driving source 2 fixedly mounted on the top of the cleaning chamber 1 and a lower driving source 3 fixedly mounted on the bottom of the cleaning chamber 1, and a stirring device 4 and a drying device 5 are arranged in the inner cavity of the cleaning chamber 1;

[0038] The stirring device 4 includes a central rod 41 and a plurality of brush plates 42 installed on the outer periphery of the central rod 41, and the lower driving source 3 drives the central rod 41 to operate;

[0039] The drying device 5 includes a circular plate 51, a rotating rod 52 arranged at the axis of the circular plate 51 through a bearing, and a plurality of filter plates 53 arranged at the bottom of the circular plate 51. A driving assembly 54 is arranged between the plurality of filter plates 53 and the rotating rod 52, so that when the driving assembly 54 is in operation, the plurality of filter plates 53 are driven to move synchronously. After the edges of the plurality of filter plates 53 overlap, the driving assembly 54 stops operating, and the upper driving source 2 drives the rotating rod 52 to operate.

[0040] A transmission member 6 is provided between the drying device 5 and the stirring device 4, so that when the center rod 41 rotates forward, the multiple brush plates 42 are driven to rotate, and when the center rod 41 rotates reversely, the rotating rod 52 is driven to rotate, so that the edges of the multiple filter plates 53 overlap and the multiple filter plates 53 are driven to rotate.

[0041] Specifically, the lower driving source 3 rotates forward and drives the center rod 41 to rotate forward, thereby driving the multiple brush plates 42 to rotate around the center rod 41 as the axis, so as to clean the parts in the cleaning chamber 1, and the lower driving source 3 rotates in the opposite direction and drives the rotating rod 52 to rotate, thereby driving the driving assembly 54 to operate, so that the four filter plates 53 move towards each other at the same time, when the outer peripheries of the four filter plates 53 are attached to each other and form a rectangular shape, the four filter plates 53 collect the parts in the cleaning chamber 1 and gather them between the four filter plates 53, and at this time the driving assembly 54 is no longer running, the center rod 41 continues to rotate in the opposite direction, so that the center rod 41 drives the rotating rod 52 to rotate, thereby driving the entire circular plate 51 to rotate, and then driving the multiple filter plates 53 in the rectangular shape to rotate around the center rod 41 as the axis;

[0042] When the center rod 41 rotates forward, it drives the brush plate 42 to clean the mechanical parts in the cleaning chamber 1. When the center rod 41 rotates reversely, it drives the rotating rod 52 to rotate, thereby driving the four filter plates 53 to enclose and make the cleaned mechanical parts located in the space between the four filter plates 53. The center rod 41 rotates continuously and makes the rotating rod 52 drive the four filter plates 53 to rotate around the center rod 41 as the axis, thereby drying the mechanical parts. This solves the problem that after the mechanical parts are cleaned, some water containing degreasing agent will adhere to the surface, which may drip onto the ground and easily pollute the environment, and the problem that the mechanical parts are in a wet state for a long time, which may easily cause rust corrosion on the parts.

[0043] Embodiment 2:

[0044] The difference from the above embodiment 1 is that, see Figure 6 - Fig. 9 For the above stirring device 4, the lower driving source 3 includes a lower servo motor 31, which is fixedly mounted at the bottom of the cleaning chamber 1. The center rod 41 is arranged in the inner cavity of the cleaning chamber 1 and is rotatably connected to the bottom of the cleaning chamber 1 through a bearing. The output end of the lower servo motor 31 is fixedly connected to the bottom end of the center rod 41. The brush plate 42 is hinged to the center rod 41 and a first torsion spring 43 is installed at the hinge. The bottom of the inner cavity of the cleaning chamber 1 is fixedly connected to a water filter plate 7, and the brush plate 42 and the filter plate 53 are arranged on the water filter plate 7.

[0045] The transmission member 6 includes a hinge plate 61, a sleeve 62 is fixedly connected to the bottom of the rotating rod 52, the top of the center rod 41 is arranged in the sleeve 62, and a plurality of baffles 63 are fixedly connected to the inner wall of the sleeve 62. The plurality of hinge plates 61 are arranged on the outer periphery of the center rod 41 and are hinged to the center rod 41. A second spring 64 is installed at the hinge between the hinge plate 61 and the center rod 41. One side of the bottom of the hinge plate 61 is set as an arc surface and is tangent to the upper surface of the center rod 41. The other side of the bottom of the hinge plate 61 is set as a plane and is attached to the upper surface of the center rod 41. The hinge plate 61 is in contact with the baffle 63.

[0046] Specifically, the lower servo motor 31 drives the central rod 41 to rotate, thereby driving the plurality of brush plates 42 to rotate around the central rod 41 as the axis, and the mechanical parts are cleaned by the brush plates 42;

[0047] When the center rod 41 rotates forward, one side of the hinge plate 61 contacts one side of the baffle 63, and by setting one side of the bottom of the hinge plate 61 as an arc surface and tangent to the upper surface of the center rod 41, the hinge plate 61 itself rotates, thereby not affecting the rotation of the rotating rod 52. When the center rod 41 rotates reversely, the other side of the hinge plate 61 contacts one side of the baffle 63, and by setting the other side of the bottom of the hinge plate 61 as a plane and in contact with the upper surface of the center rod 41, the hinge plate 61 cannot rotate itself, so that when the center rod 41 rotates, the sleeve 62 and the rotating rod 52 fixedly connected to the sleeve 62 are driven to rotate reversely.

[0048] Embodiment three:

[0049] The difference from the above-mentioned embodiment 2 is that, see Figure 4 - Figure 5 For the above-mentioned spin-drying device 5, the upper driving source 2 includes an upper servo motor 21, the output end of the upper servo motor 21 is fixedly connected to the top of the rotating rod 52, the driving assembly 54 includes two groups of driving members 541, and an inner groove 542 is provided at the bottom of the circular plate 51. One group of driving members 541 drives the filter plates 53 on both sides to make relative motion, and the other group of driving members 541 drives the filter plates 53 on the other two sides to make relative motion. One group of driving members 541 is located above the other group of driving members 541, and elastic cloth 543 is fixedly connected to the edges between the multiple filter plates 53;

[0050] The driving member 541 includes a bidirectional screw 5411, which is disposed in the inner groove 542 and is rotatably connected to the circular plate 51 through a bearing. A plurality of filter plates 53 are disposed at both ends of the bidirectional screw 5411. A right-angle plate 5412 is fixedly connected to the top of the filter plate 53. The top of the right-angle plate 5412 is threadedly connected to the bidirectional screw 5411.

[0051] The driving member 541 further comprises a worm wheel 5413 and a worm 5414. The four sides of the circular plate 51 are rotatably connected with movable rods 5415 through bearings. The worm 5414 is fixedly arranged at the bottom of the movable rod 5415. The worm wheel 5413 is fixedly connected to the middle part of the outer circumference of the bidirectional screw 5411. The worm wheel 5413 is meshedly connected with the worm 5414. The outer circumferences of the movable rod 5415 and the rotating rod 52 are provided with first tooth grooves 5416. The outer circumferences of the movable rod 5415 and the rotating rod 52 are sleeved with tooth belts 5417. The tooth belts 5417 are meshed with the rotating rod 52 and the movable rod 5415 through the first tooth grooves 5416.

[0052] Specifically, when the center rod 41 rotates in the opposite direction, the rotating rod 52 is driven to rotate in the opposite direction. The toothed belt 5417 is meshed with the movable rod 5415 and the rotating rod 52, so that when the rotating rod 52 rotates, the movable rod 5415 is driven to rotate. The meshing connection between the worm 5414 at the bottom of the movable rod 5415 and the worm wheel 5413 on the periphery of the bidirectional screw 5411 causes the movable rod 5415 to rotate, driving the bidirectional screw 5411 to rotate. The threaded connection between the bidirectional screw 5411 and the right-angle plate 5412 drives the filter plates 53 at both ends of the bidirectional screw 5411 to move toward each other, so that the four filter plates 53 are mutually connected. The filter plates 53 are moved closer together and enclosed into a rectangular shape. During the moving rod process, the elastic belt gradually recovers its elasticity and collects the mechanical parts on the water filter plate 7 between the four filter plates 53. When the four filter plates 53 stop moving, the toothed belt 5417 stops rotating, so that the rotating rod 52 cannot rotate at the bottom of the circular plate 51. Since the central rod 41 continuously drives the rotating rod 52 to rotate, the rotating rod 52 and the circular plate 51 rotate at the same time, thereby driving the rectangular filter plate 53 enclosed by the multiple filter plates 53 to rotate around the central rod 41 as the axis, thereby drying the parts in the multiple filter plates 53.

[0053] Embodiment 4:

[0054] The difference from the above-mentioned embodiment 3 is that, see Fig.10 - Fig.11 For the above-mentioned cleaning chamber 1, a scraping assembly 8 is provided at the inner wall of the cleaning chamber 1, and the scraping assembly 8 includes a scraping member 81, and a linking member 82 is provided between the scraping member 81 and the circular plate 51;

[0055] The scraping member 81 includes a plurality of scrapers 811. A sliding groove 812 is provided on the inner wall of the cleaning chamber 1. A sliding block 813 is slidably connected in the sliding groove 812. A load-bearing seat 814 is fixedly connected to one end of the sliding block 813. A rotating roller 815 is rotatably connected to the bottom of the load-bearing seat 814 through a bearing. A plurality of scrapers 811 are fixedly arranged on the outer periphery of the rotating roller 815. One end of the scraper 811 is in contact with the inner wall of the cleaning chamber 1.

[0056] The linkage 82 includes a reciprocating screw 821, which is disposed in the sliding groove 812 and is rotatably connected to the cleaning chamber 1 through a bearing. The sliding block 813 is assembled on the reciprocating screw 821 through a thread. A vertical rod 822 is fixedly connected to the top of the reciprocating screw 821, and a first gear 823 is fixedly connected to the outer periphery of the vertical rod 822. A second tooth groove 824 is provided on the outer periphery of the circular plate 51, and the first gear 823 is meshed and connected with the circular plate 51 through the second tooth groove 824.

[0057] The linkage 82 further includes a second gear 825. The two second gears 825 are rotatably disposed at both ends of the load-bearing seat 814 through bearings. One side of the second gear 825 is fixedly connected to one end of the rotating roller 815. Both sides of the inner wall of the cleaning chamber 1 are fixedly connected with a toothed plate 826. The second gear 825 is meshedly connected with the toothed plate 826.

[0058] Specifically, during the rotation of the circular plate 51, the meshing connection between the first gear 823 and the second tooth groove 824 drives the first gear 823 to rotate, thereby driving the reciprocating screw 821 to rotate, and through the threaded connection between the reciprocating screw 821 and the sliding block 813, the sliding block 813 is driven to move up and down in the sliding groove 812, thereby driving the scraper 81 to move up and down on the inner wall of the cleaning chamber 1. When the load-bearing seat 814 moves up and down on the inner wall of the cleaning chamber 1, the meshing connection between the second gear 825 and the tooth plate 826 drives the second gear 825 to rotate, thereby driving the rotating roller 815 to rotate, and then driving the scraper 811 to scrape the inner wall of the cleaning chamber 1.

[0059] Embodiment five:

[0060] See also Figure 1 - Fig.11 This embodiment discloses a cleaning method for precision parts after processing, and the specific steps are as follows:

[0061] The lower driving source 3 rotates forward and drives the center rod 41 to rotate forward, thereby driving the multiple brush plates 42 to rotate around the center rod 41 as the axis, thereby cleaning the parts in the cleaning chamber 1, and the lower driving source 3 rotates reversely and drives the rotating rod 52 to rotate, thereby driving the driving assembly 54 to operate, so that the four filter plates 53 move towards each other at the same time. When the outer peripheries of the four filter plates 53 are attached to each other and form a rectangular shape, the four filter plates 53 collect the parts in the cleaning chamber 1 and gather them between the four filter plates 53, and at this time the driving assembly 54 no longer operates, and the center rod 41 continues to rotate reversely, so that the center rod 41 drives the rotating rod 52 to rotate, thereby driving the entire circular plate 51 to rotate, and then driving the multiple filter plates 53 formed in a rectangular shape to rotate around the center rod 41 as the axis.

[0062] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

6. A cleaning method for precision parts after machining, characterized in that: The oil cleaning device according to any one of claims 1 to 5 is used, and the specific steps are as follows: The lower driving source rotates forward and drives the center rod to rotate forward, thereby driving multiple brush plates to rotate around the center rod as the axis, thereby cleaning the parts in the cleaning bin. The lower driving source rotates reversely and drives the rotating rod to rotate, thereby driving the driving assembly to operate, so that the four filter plates move towards each other at the same time. When the outer peripheries of the four filter plates are attached to each other and form a rectangular shape, the four filter plates collect the parts in the cleaning bin and gather them between the four filter plates. At this time, the driving assembly no longer operates, and the center rod continues to rotate reversely, so that the center rod drives the rotating rod to rotate, thereby driving the entire circular plate to rotate, and then driving the multiple filter plates formed in a rectangular shape to rotate around the center rod as the axis.
