[0041] 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.
[0042] Embodiment 1:
[0043] like Figures 1 to 7As shown, a first embodiment of the present invention provides a slewing bearing cleaning device for cleaning the outer ring or inner ring of a processed slewing bearing, and specifically includes a cleaning box 1 containing a cleaning liquid and a positioning assembly, the positioning assembly is used to carry the workpiece, and the side of the cleaning box 1 is also provided with a displacement assembly and a lifting assembly, the lifting assembly functions to lift or lower the positioning assembly so that the positioning assembly can lift the workpiece to a certain height, and the lifting assembly can be a conventional crane, hoist or lifting hydraulic rod and other equipment. The displacement assembly functions to move the lifting assembly horizontally, and the displacement assembly can be a track or other equipment. The lifting assembly and the displacement assembly of the present invention adopt conventional design without special improvements. The lifting assembly and the displacement assembly cooperate to lift and move the positioning assembly, so that the positioning assembly can lift the workpiece and place it in the cleaning box 1.
[0044] See also Figures 3 to 5 The positioning assembly of the present invention comprises a base plate 2 and three lifting units evenly arranged below the base plate 2, and the lifting units can move along the radial direction of the base plate 2. Specifically, as Figure 4 As shown, three slide grooves 3 extending along the radial direction of the base plate 2 are provided on the base plate 2, and a cantilever 4 is slidably installed in each slide groove 3, and the three cantilevers 4 can move in the slide groove 3 at the same time. Figure 3 As shown, each lifting unit includes a column 5 rotatably mounted at the end of a cantilever 4, a horizontal support roller 6 is mounted on the column 5, and vertical support rollers 7 are symmetrically mounted on both sides of the column 5. Figure 2 As shown, the horizontal support roller 6 can lift the lower surface of the workpiece. Figure 6 and Figure 7 As shown, the two vertical support rollers 7 can then bear against the inner ring surface or the outer ring surface of the workpiece.
[0045] by Figure 6 For example, when the three cantilevers 4 move away from the axis of the base plate 2, the three lifting units move along the radial direction of the base plate 2, and the two vertical support rollers 7 on each lifting unit can be pressed against the inner ring surface without tooth patterns on the workpiece. When the vertical support rollers 7 of the three sets of lifting units are pressed against the workpiece, the center of the workpiece can be positioned on the axis of the base plate 2. Since the bottom of the workpiece is supported by the horizontal support rollers 6, the workpiece is limited by the positioning assembly at this time. When the positioning assembly is lifted and moved, it will drive the workpiece to lift and move.
[0046] In order to better clean the workpiece, the present invention is provided with a plurality of nozzles for flushing the slewing bearing in the cleaning box 1. The nozzle can spray the cleaning liquid onto the workpiece, thereby flushing away the debris and oil stains on the surface of the workpiece. Some slewing bearings may have teeth, and the side of the workpiece with the teeth is prone to have a blind spot that cannot be sprayed by the nozzle. Therefore, the present invention is provided with a brushing assembly on one of the lifting units, and a driving structure for driving the horizontal support roller 6 to rotate is provided on the base plate 2. When the driving assembly is working, the horizontal support roller 6 can rotate, so that the workpiece rotates around the axis of the base plate 2, and the brush roller 8 in the brushing assembly will also rotate to brush the tooth surface of the workpiece. In view of the large thickness of some workpieces, in order to more effectively brush the tooth surface of the workpiece, the brush roller 8 of the present invention is designed to be rotatable and simultaneously raised and lowered to fully contact and clean the tooth surface.
[0047] Embodiment 2:
[0048] On the basis of the first embodiment, the present invention is to realize the simultaneous driving of three cantilevers 4 to move in the chute 3, such as Figure 4 As shown, in the present invention, a screw rod 28 is rotatably installed in each of the three slide grooves 3 on the base plate 2, and the screw rod 28 is threadedly matched with the corresponding cantilever 4, so that by driving the three screw rods 28 to rotate at the same time, the cantilever 4 can be driven to move at the same time. In the present invention, a third bevel gear 29 is fixedly installed at one end of the screw rod 28 close to the axis of the base plate 2, and a hollow rotating drum 30 is rotatably installed at the center of the base plate 2, and a fourth bevel gear 31 that meshes with the three third bevel gears 29 is fixed on the rotating drum 30. Figure 1 As shown, a motor 32 for driving the rotating drum 30 is fixed on the base plate 2. When the motor 32 is working, the rotating drum 30 can be driven to rotate, and then the cantilever 4 is controlled to move simultaneously in the slide 3 through the three screw rods 28, so as to drive the three lifting units to press against the outer ring or inner ring of the workpiece.
[0049] In order to simultaneously drive the three horizontal support rollers 6 to rotate, thereby rotating the workpiece, the driving structure provided in the present invention includes a rotating shaft 11 inserted into the rotating drum 30, and a motor 32 for driving the rotating shaft 11 to rotate is fixed on the base plate 2. Figure 4 As shown, a first bevel gear 12 is fixed to one end of the rotating shaft 11. Three sleeves 13 are also rotatably mounted on the base plate 2. The three sleeves 13 are parallel to the three screw rods 28 respectively. A second bevel gear 14 meshing with the first bevel gear 12 is fixed to one end of the sleeve 13 close to the rotating shaft 11, so that the three sleeves 13 can be driven to rotate simultaneously when the rotating shaft 11 rotates. A slide bar 15 is rotatably mounted on each cantilever 4. The slide bar 15 is movably inserted in the corresponding sleeve 13 and is driven by the sleeve 13 through a spline, so that when the cantilever 4 moves in the slide slot 3, the rotating shaft 11 can still drive the slide bar 15 on the cantilever 4 to rotate.
[0050] A rotatable sleeve 10 is mounted on the column 5, and the transmission is realized between the sleeve 10 and the slide rod 15 through a bevel gear set. Figure 6 and Figure 7 When the column 5 is pressed against the workpiece as in the above, it is impossible to rotate. At this time, the rotating shaft 11 rotates to drive the rotating sleeve 10 to rotate through the sliding rod 15.
[0051] like Figure 5 As shown, a transmission shaft 9 parallel to the column 5 is installed on one side of the column 5 through a bearing seat, the upper end of the transmission shaft 9 is connected to the rotating sleeve 10 through a spur gear set, and the lower end of the transmission shaft 9 is connected to the roller shaft of the horizontal support roller 6 through a bevel gear set, so that the horizontal support roller 6 can be driven to rotate when the rotating sleeve 10 rotates.
[0052] Through the above arrangement, when the rotating shaft 11 rotates, it can drive the three horizontal support rollers 6 to rotate, and when the rotating drum 30 rotates, it can drive the three cantilevers 4 to move with the lifting units.
[0053] Embodiment three:
[0054] On the basis of Example 1 and Example 2, in order to prevent the position of the brush roller 8 from affecting the lifting unit's carrying of the workpiece, the brushing assembly includes a slide 16 slidably mounted on the column 5, the brush roller 8 is arranged on the slide 16, and an electric push rod 17 is fixedly mounted on the column 5. The movable end of the electric push rod 17 is fixedly connected to the slide 16. When the electric push rod 17 is working, it can control the slide 16 to rise and fall and slide on the column 5, thereby adjusting the position of the brush roller 8.
[0055] Since the brush roller 8 may cause splashing of cleaning liquid when brushing the workpiece in the cleaning box 1, a transmission structure is designed between the brush roller 8 and the transmission shaft 9 so that the brush roller 8 can be driven to rotate and rise and fall when the transmission shaft 9 rotates, instead of directly installing the motor 32 on the slide 16 to prevent the cleaning liquid from damaging the motor 32.
[0056] like Figure 5 As shown, the transmission structure designed in the present invention includes a first cylinder 18 and a second cylinder 19 rotatably mounted on a slide 16, wherein the first cylinder 18 is sleeved on the transmission shaft 9 and is splined with the transmission shaft 9; and a driven shaft 20 is movably inserted into the second cylinder 19, and the driven shaft 20 is splined with the second cylinder 19. The first cylinder 18 and the second cylinder 19 are connected by a synchronous belt transmission mechanism, so that when the transmission shaft 9 rotates, the driven shaft 20 can be driven to rotate.
[0057] The brush roller 8 is rotatably mounted on the mounting frame 22. A guide column 21 parallel to the column 5 is fixed on the slide 16, and the mounting frame 22 is slidably matched with the guide column 21. The lower end of the driven shaft 20 is rotatably mounted on the mounting frame 22. Since the driven shaft 20 is located above the middle of the brush roller 8 in the present invention, a connecting shaft 27 is rotatably mounted on the mounting frame 22 in the present invention, one end of the connecting shaft 27 is connected to the driven shaft 20 through a bevel gear set, and the other end is connected to the roller shaft of the brush roller 8 through a belt transmission mechanism. In this way, when the driven shaft 20 rotates, the brush roller 8 can be driven to rotate.
[0058] In order to allow the brush roller 8 to reciprocate and rise and fall, the brushing assembly designed by the present invention also includes a gear 1 23 fixed on the second cylinder 19 and a gear 2 24 rotatably mounted on the mounting frame 22. Gear 2 24 meshes with gear 1 23, and an eccentric rod 25 is fixed on gear 2 24. When the driven shaft 20 rotates, gear 2 24 rotates. Since the axis of gear 2 24 is perpendicular to the column 5, when the eccentric rod 25 rotates with the axis of gear 2 24 as the center, a height change will occur. A limit frame 26 is fixed on the mounting frame 22, and the eccentric rod 25 is slidably mounted in the limit frame 26. The sliding direction of the eccentric rod 25 in the limit frame 26 is horizontal. When gear 2 24 rotates, it can drive the limit frame 26 to reciprocate and rise and fall, and then the mounting frame 22 can be reciprocated and raised on the guide column 21, thereby realizing the reciprocating brushing action of the brush roller 8 on the tooth surface of the workpiece.
[0059] Through the above arrangement, the brush roller 8 can be driven by the rotating shaft 11 to rotate and reciprocate and rise and fall to brush the tooth surface of the workpiece. At the same time, the horizontal support roller 6 rotates with the workpiece, changing the brushing position of the brush roller 8, so that the brush roller 8 can fully brush all the tooth surfaces of the workpiece and complete the cleaning of the slewing bearing.
[0060] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
