[0038] 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.

[0039] Embodiment 1:

[0040] like Figures 1 to 9 As shown, the first embodiment of the present invention provides a gear cleaning device, which specifically includes a cleaning box 1, a conveying mechanism and a plurality of nozzles 10 arranged in the cleaning box 1. The nozzles 10 are connected to a detergent supply device and can spray detergent downward. The conveying mechanism includes a circulating track fixed on a frame, and the circulating track can be divided into an upper track, a lower track and a connecting track for connecting the upper track and the lower track. The lower track passes through the cleaning box 1. As shown in FIG. Figure 2 As shown, the nozzle 10 is specifically fixed on the top inner wall of the cleaning box 1, and many positioning components 4 for carrying the gears to be cleaned are slidably installed on the circulating track. When the positioning components 4 move along the lower track in the cleaning box 1, the roller brush 2 installed in the cleaning box 1 can rotate to brush the gears on the positioning components 4, and at the same time, the nozzle 10 also sprays detergent to the gears to clean the gears.

[0041] There is often a fixed contact part between the conventional positioning device and the gear, which makes it impossible to clean the part. However, there is a certain floating space between the positioning assembly 4 and the gear set in the present invention, so as to avoid the occurrence of cleaning dead corners. Specifically, the positioning assembly 4 of the present invention includes a slide 5 slidably mounted on a circulating track, a rotating shaft 6 that can rotate is mounted on one side of the slide 5, an extension bar 21 is fixed to the end of the rotating shaft 6 away from the slide 5, and a flat body 7 is hinged to the end of the extension bar 21 away from the slide 5 through a first hinge shaft 22. Figure 5 and Figure 6As shown, the gear to be cleaned can be sleeved on the flat body 7. The diameter of the circumscribed circle of the flat body 7 is smaller than the diameter of the shaft hole of the gear, so the gear has a certain upward and downward movement space on the flat body 7. In order to facilitate the sleeve of the gear on the flat body 7, a guide cone 26 is provided at one end of the flat body 7 away from the slide seat 5. At the same time, a toothed pad 27 for anti-slip is provided on the flat body 7 to increase the friction between the flat body 7 and the gear.

[0042] When the flat body 7 rotates with the shaft 6, the two contact positions of the flat body 7 and the gear shaft hole will change with the rotation of the flat body 7, and the flat body 7 will rotate with the gear. When one side of the flat body 7 is against the keyway of the gear shaft hole, and the other side is against other positions of the shaft hole, as the flat body 7 rotates, the flat body 7 can effectively move the gear to rotate. However, a general suspension rod may get stuck in the keyway. When the rod rotates, the rod only rotates in the keyway and cannot rotate the gear as a whole.

[0043] The flat body 7 provided in the present invention has six first stop bars 8 fixed to one end close to the slide 5, and the flat body 7 has a second stop bar 9 hinged to one end away from the slide 5 through a second hinge shaft 24; at the same time, a driving mechanism is provided in the cleaning box 1, and an angle adjustment mechanism cooperating with the driving mechanism is provided on the positioning assembly 4. When the positioning assembly 4 cooperates with the driving mechanism, the rotating shaft 6 rotates, and the angle adjustment mechanism makes the flat body 7 tilted or horizontal, and at the same time drives the second stop bar 9 to rotate. Figure 6 and Fig. 9 As shown, when the flat body 7 is tilted, the second stop bar 9 will also rotate, thereby cooperating with the first stop bar 8 to limit the gear on the flat body 7 and tilt the gear, so that the spray head 10 above can spray detergent into the shaft hole of the gear.

[0044] like Figures 1 to 4 As shown, the driving mechanism designed by the present invention includes a first rack 11 and a second rack 12 fixed on the cleaning box 1, and a spur gear 13 is fixed on each rotating shaft 6. The first rack 11 and the second rack 12 are arranged in a staggered manner and are respectively located on the upper and lower sides of the spur gear 13. When the slide 5 moves on the circulating slide 3 and the spur gear 13 is meshed with the first rack 11, the spur gear 13 will not contact the second rack 12. As the slide 5 moves, the spur gear 13 rolls on the first rack 11, driving the rotating shaft 6 to rotate; when the slide 5 moves on the circulating slide 3 and the spur gear 13 is meshed with the second rack 12, the spur gear 13 is no longer in contact with the first rack 11. At this time, the spur gear 13 rolls on the second rack 12, and the direction of rotation of the rotating shaft 6 is opposite to the direction of rotation when the spur gear 13 is meshed with the first rack 11. Through the above arrangement, when the positioning assembly 4 moves along the circulating slide rail 3, the rotating shaft 6 and the flat body 7 rotate, thereby causing the gear to rotate continuously, changing the contact position with the roller brush 2, so that all tooth root positions of the gear can be brushed by the roller brush 2.

[0045] The present invention makes the positioning assembly 4 appear when it moves along the circulating slide rail 3 Figure 5 and Fig. 9 The flat body 7 shown in the figure is tilted and horizontally changed. The angle adjustment mechanism designed by the present invention includes an adjustment sleeve 14 threadedly mounted on the rotating shaft 6, a rotating sleeve 15 sleeved on the rotating shaft 6 and rotatingly matched with the adjustment sleeve 14, an extension rod 16 fixed on the flat body 7 and a connecting rod 17, one end of the connecting rod 17 is hinged on the extension rod 16, and the other end is hinged on the rotating sleeve 15. Through the above arrangement, when the adjustment sleeve 14 and the rotating shaft 6 rotate relative to each other, the adjustment sleeve 14 will move along the axis of the rotating shaft 6, and then drive the connecting rod 17 through the rotating sleeve 15, so that the connecting rod 17 pulls the extension rod 16, so that the flat body 7 rotates around the first hinge shaft 22, thereby causing the flat body 7 to rotate from the first hinge shaft 22 to the first hinge shaft 22. Figures 5 to 9 changes, or changes from Figure 9 to Figure 5 changes.

[0046] In order to allow the adjustment sleeve 14 to rotate relative to the rotating shaft 6, the present invention provides a limiting portion 18 on the adjustment sleeve 14, and a first limiting plate 19 and a second limiting plate 20 are fixed on the cleaning box 1. Figures 1 to 4 As shown, when the positioning assembly 4 moves to the point where the spur gear 13 meshes with the first rack 11 and the limiting portion 18 contacts the first limiting plate 19, the limiting portion 18 is blocked by the first limiting plate 19, so that the adjustment sleeve 14 cannot rotate, while the rotating shaft 6 can rotate, so the adjustment sleeve 14 will rotate relative to the rotating shaft 6, and the adjustment sleeve 14 will move along the axis of the rotating shaft 6, so that the flat body 7 rotates around the first hinge shaft 22. Similarly, when the positioning assembly 4 moves to the point where the spur gear 13 meshes with the second rack 12 and the limiting portion 18 contacts the second limiting plate 20, the limiting portion 18 is blocked by the second limiting plate 20, so that the adjustment sleeve 14 cannot rotate, while the rotating shaft 6 can rotate, so the adjustment sleeve 14 will rotate relative to the rotating shaft 6, and the rotation direction is opposite to the previous one, and the adjustment sleeve 14 will move and reset along the axis of the rotating shaft 6, so that the flat body 7 rotates to the original angle around the first hinge shaft 22.

[0047] Considering that when the flat body 7 is in an inclined state, the second stop bar 9 also needs to be able to rotate to a certain angle, so as to Figure 5 Rotate the position shown to Figure 8 The position shown in the figure can cooperate with the first stop bar 8 to limit the position of the gear, so as to prevent the gear from sliding off the flat body 7 when the shaft 6 rotates. Figure 8As shown, the present invention is provided with a first tooth pattern 23 at one end of the extension bar 21 close to the first stop bar 8, and the first tooth pattern 23 surrounds the first hinge shaft 22; the second stop bar 9 is provided with a second tooth pattern 25 meshing with the first tooth pattern 23, and the second tooth pattern 25 surrounds the second hinge shaft 24. In this way, when the angle between the flat body 7 and the extension bar 21 changes, the first tooth pattern 23 will move the second tooth pattern 25, so that the second stop bar 9 rotates around the second hinge shaft 24.

[0048] Working principle: The gear to be cleaned is put onto the flat body 7 through the horizontal second stop bar 9 and the guide cone 26. Since the flat body 7 is in a horizontal state at this time, the gear will not fall off the flat body 7. As the slide 5 moves on the circulating slide rail 3, the spur gear 13 first meshes with the first rack 11, so that the flat body 7 and the rotating shaft 6 rotate, allowing the gear to be cleaned to rotate accordingly, so that the roller brush 2 below and the nozzle 10 above can brush and spray the tooth surface and tooth root of the gear; then the limiting part 18 cooperates with the first limiting plate 19 to move the adjustment sleeve 14 on the rotating shaft 6, so that the flat body 7 rotates around the first hinge shaft 22, and the second baffle bar 9 rotates around the second hinge shaft 24, so that the gear to be cleaned is tilted, and then in the tilted state, the gear continues to rotate with the rotating shaft 6, so that the nozzle 10 above can spray the side and inner hole of the gear; finally, the limiting part 18 cooperates with the second limiting plate 20, and the spur gear 13 cooperates with the second rack 12, so that the adjustment sleeve moves in the opposite direction, so that the flat body 7 is reset to a horizontal state, and the gear is also fully cleaned.

[0049] Embodiment 2:

[0050] On the basis of Example 1, in order to realize the movement of the slide 5 on the circulating slide rail 3, the conveying mechanism designed by the present invention also includes two sprockets 28 rotatably mounted on the frame and a chain 29 wound around the two sprockets 28. A motor for driving one of the sprockets 28 to rotate is fixed on the frame, and each slide 5 is provided with an ear plate connected to the chain 29. Therefore, when the motor drives the chain 29 to rotate in a circular motion, it can drive the slide 5 to move in a circular motion on the circulating slide rail 3.

[0051] Embodiment three:

[0052] On the basis of the first and second embodiments, the roller brush 2 designed by the present invention comprises a roller shaft and a spiral plate fixed on the roller shaft, the roller shaft is rotatably mounted on the cleaning box 1, one end of the roller shaft extends out of the cleaning box 1 and is driven to rotate by a motor. Bristles are fixed on the spiral plate. The bristles are distributed along the spiral plate and are also spiral-shaped. When the roller brush 2 rotates, the bristles cooperate with the tooth root and tooth surface of the gear, and can also play a role in promoting the rotation of the gear, so that the bristles can brush all the tooth root and tooth surface.

[0053] 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.
