Description

Technical Field

[0001] This invention belongs to the technical field of automatic gearbox housing cleaning equipment, specifically relating to an automatic supply device for a loader gearbox housing cleaning machine. Background Technology

[0002] Before assembly, the gearbox housing typically needs to be cleaned to remove oil, dust, metal shavings, and other impurities. This prevents accelerated wear of internal parts after assembly and extends the gearbox's lifespan. Currently, gearbox housing cleaning is usually done automatically using mechanized methods, which effectively improves cleaning efficiency and reduces labor costs. For example, a Chinese patent discloses an automatic supply device for a loader gearbox housing cleaning machine (patent publication number: CN114713584A). By installing a gear in the middle of the connecting shaft and connecting a rack to the front of the connecting frame via a support frame, when the placement plate engages with the gear and rack via the connecting shaft, the placement plate rotates as it moves to the right. This allows the placement plate to rotate and enter the cleaning area within the cleaning machine body, enabling comprehensive cleaning of the gearbox housing from all sides.

[0003] Although the above technical solution achieves automatic and continuous cleaning of the gearbox housing, in the actual cleaning process, when the gearbox housing is placed on the placement plate and passes over the cleaning machine body, even if the placement plate rotates the gearbox housing, there are still some dead corners in the cleaning of the gearbox housing, and the surface of the gearbox housing cannot be cleaned in all directions. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an automatic supply device for a loader gearbox housing cleaning machine, so as to solve the problem that there are blind spots in the cleaning of existing gearbox housings, and they cannot be completely cleaned.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An automatic supply device for cleaning a loader gearbox housing includes a clamping unit for holding the gearbox housing, a conveying unit for transferring the clamping unit, and a cleaning unit for cleaning the gearbox housing. The clamping unit includes a fixed housing arranged annularly around the gearbox housing and a first telescopic rod and a second telescopic rod mounted on the fixed housing. Multiple first and second telescopic rods are provided, symmetrically arranged about the axis along the length of the gearbox housing. The first and second telescopic rods on the same side are staggered along a horizontal plane. The telescopic ends of the first and second telescopic rods extend out and abut against the gearbox housing. The surface of the gearbox housing; the cleaning unit includes a cleaning tank and an ultrasonic generator acting on the cleaning tank. The cleaning tank contains cleaning fluid for cleaning the gearbox housing, and the cleaning fluid vibrates under the action of the ultrasonic generator; the conveying unit includes a conveying mechanism and multiple transfer trays connected to the conveying mechanism. Part of the conveying route of the conveying mechanism is set above the cleaning tank and arranged along the length of the cleaning tank. Each transfer tray is connected to a clamping unit below it, and when the clamping unit is conveyed to the top of the cleaning tank, the gearbox housing is completely submerged in the cleaning fluid and moves a distance along the length of the cleaning tank.

[0007] Furthermore, the upper surface of the fixed housing is connected to a rotating mechanism that drives it to rotate. The rotating mechanism includes a support housing that is sleeved on and rotatably mounted on the fixed housing and a drive motor mounted on the surface of the support housing. The support housing is located below the corresponding transfer tray. A transmission component is connected between the output end of the drive motor and the fixed housing, and the drive motor drives the fixed housing to rotate along its horizontal axis through the transmission component.

[0008] Furthermore, the rotating mechanism also includes a turntable rotatably mounted on the support housing. The turntable is horizontally positioned with its axis pointing vertically upward. The turntable is positioned below and fixedly connected to the corresponding transfer tray. A transmission component is connected between the output end of the drive motor and the turntable. While the drive motor drives the fixed housing to rotate, it also drives the support housing to rotate around the vertical axis of the turntable through the transmission component.

[0009] Furthermore, multiple vertically arranged telescopic rods are connected between the upper surface of the turntable and the transfer tray. These telescopic rods are evenly spaced around the circumference of the turntable. Each telescopic rod includes a movable rod fixedly connected to the surface of the turntable and a fixed rod fixedly connected to the lower surface of the transfer tray. Each movable rod is elastically inserted through the lower end of a corresponding fixed rod. The multiple movable rods are jointly fixedly connected to a horizontally arranged movable plate. The side surface of the movable plate is provided with multiple rollers, which are symmetrically arranged about the horizontal axis of the movable plate. Two tracks that cooperate with the rollers are mounted above the cleaning tank. The two tracks extend along the length of the cleaning tank and are symmetrically arranged about the axis of the length of the cleaning tank. The surface of each track is provided with multiple protrusions that cooperate with the rollers at intervals along its length.

[0010] Furthermore, the surface of each protrusion that contacts the roller is a continuous smooth curved surface, and the distance between any two adjacent protrusions on the same track is equal to the distance between two adjacent rollers.

[0011] Furthermore, the cleaning tank is equipped with a heating component for increasing the temperature of the cleaning fluid.

[0012] Furthermore, the fixed housing is barrel-shaped, and multiple through holes are provided on the peripheral surface of the fixed housing.

[0013] The beneficial effects of this invention are as follows:

[0014] 1. The present invention, through the cooperation of the conveying unit and the clamping unit, can automatically and continuously transport multiple gearbox housings into the cleaning tank. The working end of the ultrasonic generator is located in the cleaning fluid, which can cause the cleaning fluid to vibrate at high frequency and thoroughly clean the oil and impurities attached to the surface of the gearbox housing. By alternately clamping the gearbox housing with the first telescopic rod and the second telescopic rod, the dead corners during cleaning can be reduced to the greatest extent and the cleaning efficiency can be improved.

[0015] 2. A rotating mechanism is provided on the surface of the clamping mechanism. When the gearbox housing is in the cleaning fluid, the rotating mechanism can drive the gearbox housing to rotate simultaneously around the axis of the fixed housing and around the axis of the turntable. Furthermore, through the cooperation of the rollers and the protrusions, the gearbox housing can generate vibration while rotating, which can further agitate the cleaning fluid, so that the cleaning fluid can effectively flush and clean the impurities on the surface of the gearbox housing, thereby improving the cleaning efficiency.

[0016] Other advantages, objectives, and features of the invention will be set forth in the following description and will be apparent to those skilled in the art in some respects, or may be learned by practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

Detailed Implementation

[0028] like Figures 1 to 8 As shown,

[0029] An automatic supply device for cleaning a loader gearbox housing includes a clamping unit 1 for clamping a gearbox housing 12, a conveying unit 2 for transferring the clamping unit 1, and a cleaning unit for cleaning the gearbox housing 12. The clamping unit 1 includes a fixed housing 101 annularly arranged around the gearbox housing 12, and first telescopic rods 102 and second telescopic rods 103 mounted on the fixed housing 101. There are two first telescopic rods 102 and four second telescopic rods 103. The first telescopic rods 102 and second telescopic rods 103 are symmetrically arranged about the axis of the gearbox housing 12 along its length. On the same side, a first telescopic rod 102 is positioned between two second telescopic rods 103. The telescopic ends of the first telescopic rods 102 and second telescopic rods 103 are all bolted to abutment blocks for abutting against the surface of the gearbox housing 12. The cleaning unit includes a cleaning tank 3 and an ultrasonic generator (not shown in the figure) acting on the cleaning tank 3. The cleaning tank 3 contains cleaning fluid for cleaning the gearbox housing 12, and the cleaning fluid vibrates at high frequency under the action of the ultrasonic generator. The conveying unit 2 includes a conveying mechanism and multiple transfer trays 202 connected to the conveying mechanism (the conveying mechanism is not shown in the figure; the conveying mechanism can use existing known conveying devices such as conveyor belts, sprockets, and chains, and the existing technology will not be described in detail). Part of the conveying route of the conveying mechanism is set above the cleaning tank 3 and is arranged along the length of the cleaning tank 3. Each transfer tray 202 is connected to the clamping unit 1 below, and when the clamping unit 1 is conveyed to the top of the cleaning tank 3, the gearbox housing 12 is completely submerged in the cleaning fluid and moves a distance along the length of the cleaning tank 3.

[0030] The conveying mechanism located above the cleaning pool 3 is divided into a transfer section and a cleaning section. The horizontal height of the conveying mechanism in the cleaning section is lower than that of the conveying mechanism in the transfer section. There is an inclined transition section between the cleaning section and the transfer section. The purpose is to fully immerse the gearbox housing 12 in the cleaning fluid for thorough cleaning. Furthermore, the conveying mechanism located above the cleaning pool 3 is fixedly connected to a support frame 201 by bolts.

[0031] As shown in the figure, which only shows a partial schematic of the conveying mechanism and only one clamping unit 1, when the gearbox housing 12 needs to be cleaned, the gearbox housing 12 is first moved into the corresponding clamping unit 1. Multiple first telescopic rods 102 and second telescopic rods 103 clamp and fix the gearbox housing 12 to the fixed housing 101. Then, the conveying mechanism drives the fixed housing 101 towards the cleaning pool 3 via a tray. The clamping unit 1 moves a distance along the length of the cleaning pool 3 under the action of the conveying mechanism. Simultaneously, the gearbox housing 12 is completely submerged in the cleaning fluid, and the fluid is agitated during the movement. The cleaning fluid is then activated by the ultrasonic generator. Under the action of the cleaning fluid, high-frequency vibration occurs. The combined effect of the two can clean away the oil stains and other debris attached to the surface of the gearbox housing 12. During the movement of the gearbox housing 12 after it is immersed in the cleaning fluid, multiple first telescopic rods 102 and second telescopic rods 103 cooperate with each other to alternately clamp and fix the gearbox housing 12, reducing the cleaning dead corners caused by the abutment block abutting the surface of the gearbox housing 12. This effectively increases the cleaning area and cleaning efficiency of the gearbox housing 12 and minimizes the cleaning dead corners. Furthermore, through the cooperation of the conveying unit and the clamping unit 1, continuous automated cleaning of multiple gearbox housings 12 can be achieved, greatly improving the cleaning efficiency and the degree of cleanliness.

[0032] In this embodiment, a rotating mechanism is connected to the upper surface of the fixed housing 101 to drive its rotation. The rotating mechanism includes a support housing 4 sleeved and rotatably disposed on the fixed housing 101 and a drive motor 5 fixedly mounted on the surface of the support housing 4 by bolts. The support housing 4 is disposed below the corresponding transfer tray 202. A transmission component is connected between the output end of the drive motor 5 and the fixed housing 101. The transmission component includes a sprocket disposed at the output end of the drive motor 5 and on the surface of the fixed housing 101. A chain is connected between the two sprockets. The drive motor 5 drives the fixed housing 101 to rotate along its horizontal axis through the transmission of the sprocket and chain.

[0033] Combination Figure 2 As shown, the fixed housing 101 is tubular, and the supporting housing 4 is inverted "U" shape. The supporting housing 4 is mounted above the fixed housing 101. When the clamping unit 1 is submerged in the cleaning fluid under the drive of the conveying mechanism, the drive motor 5 starts and drives the fixed housing 101 to rotate along its axis through the sprocket and chain. While the fixed housing 101 rotates, it will also drive the clamped gearbox housing 12 to rotate together, which can further agitate the cleaning fluid, improve the cleaning degree of the gearbox housing 12 and reduce the dead angles during cleaning.

[0034] In this embodiment, the rotating mechanism further includes a turntable 6 rotatably mounted on the support housing 4. The turntable 6 is horizontally mounted with its axis pointing vertically upward. The vertical axis of the turntable 6 is on the same straight line as the vertical rotation center of the support housing 4. The turntable 6 is mounted below and fixedly connected to the corresponding transfer tray 202. A bevel gear set is connected between the output end of the drive motor 5 and the upper surface of the turntable 6 for transmission. While the drive motor 5 drives the fixed housing 101 to rotate, it also drives the support housing 4 to rotate around the vertical axis of the turntable 6 through the bevel gear set.

[0035] As shown in the figure, the upper surface of the turntable 6 is fixedly connected to the transfer tray 202, and the support housing 4 is rotatably set on the outer ring surface of the turntable 6. When the drive motor 5 starts, it drives the fixed housing 101 to rotate. At the same time, the output end of the drive motor 5 drives the support housing 4 to rotate around the axis of the turntable 6 through the bevel gear set. This causes the gearbox housing 12 to rotate around the axis of the fixed housing 101 and also around the axis of the turntable 6. The two work together to further agitate the cleaning fluid, improve the cleaning efficiency and reduce cleaning dead angles.

[0036] In this embodiment, five vertically arranged telescopic rods 7 are connected between the upper surface of the turntable 6 and the transfer tray 202. Four of the telescopic rods 7 are evenly spaced around the circumference of the turntable 6, and the other telescopic rod 7 is arranged along the axis of the turntable 6. Each telescopic rod 7 includes a movable rod 701 fixedly connected to the upper surface of the turntable 6 and a fixed rod 702 fixedly connected to the lower surface of the transfer tray 202. Each movable rod 701 is elastically inserted through the lower end of the corresponding fixed rod 702 (a spring is provided between the movable rod 701 and the fixed rod 702, which is not shown in the figure). Multiple movable rods 701 are fixedly connected to a horizontally arranged movable plate 8. The side surface of the movable plate 8 is provided with multiple rollers 9, and the multiple rollers 9 are symmetrically arranged about the horizontal axis of the movable plate 8. Two tracks 10 that cooperate with the rollers 9 are mounted above the cleaning pool 3. The two tracks 10 extend along the length direction of the cleaning pool 3 and are symmetrically arranged about the axis of the length direction of the cleaning pool 3. The surface of each track 10 is provided with multiple protrusions 11 that cooperate with the rollers 9 at intervals along its length direction. Each protrusion 11 protrudes vertically upward from the surface of the track 10.

[0037] As shown in the figure, when the clamping unit 1 enters the cleaning tank 3 under the drive of the conveying mechanism, the rollers 9 on both sides of the movable plate 8 also cooperate with the corresponding tracks 10. When the rollers 9 move along the length of the track 10, they intermittently abut against the protrusions 11 on the track 10. After multiple protrusions 11 abut against the rollers 9, they will cause the rollers 9 to move up and down in the vertical direction. The rollers 9 on both sides will simultaneously drive the movable plate 8 to move up and down in sync. The movable plate 8 drives the gearbox housing 12 to move up and down in the cleaning tank 3 through the movable rod 701, the turntable 6, and the clamping unit 1, which can further agitate the cleaning fluid, improve the cleaning efficiency, and reduce the cleaning dead angles. Among them, since the movable rod 701 is elastically inserted under the corresponding fixed rod 702, When the roller 9 abuts against the protrusion 11 and moves vertically upward, the movable plate 8 will also drive each movable rod 701 to move vertically upward. At this time, the spring between the movable rod 701 and the fixed rod 702 is compressed and accumulates elastic potential energy. When the roller 9 continues to move along the length of the track 10 and no longer abuts against the protrusion 11, the compressed spring resets and releases elastic potential energy. Since the lower end of the movable rod 701 is connected to the turntable 6 and the clamping unit 1 and other components, its gravitational potential energy plus the elastic potential energy of the spring can make the roller 9 not only move up and down in the vertical direction after passing the protrusion 11, but also generate a certain vibration, which indirectly causes the clamped gearbox housing 12 to vibrate, which can further disturb the cleaning fluid and improve the cleaning degree.

[0038] In this embodiment, the surface of each protrusion 11 that contacts the roller 9 is a continuous smooth curved surface, and the distance between any two adjacent protrusions 11 on the same track 10 is equal to the distance between two adjacent rollers 9.

[0039] The smooth surface of the protrusion 11 can improve the smoothness of each roller 9 when it passes by. Since the multiple rollers 9 are symmetrically arranged about the movable plate 8, when each roller 9 is in contact with the track 10, each roller 9 will contact the protrusion 11 at the same time during the movement, and together drive the movable plate 8 to move in the vertical direction, which can improve the stability of the movable plate 8 during movement.

[0040] In this embodiment, the cleaning tank 3 is equipped with a heating component to increase the temperature of the cleaning fluid, which can keep the temperature of the cleaning fluid at the optimal level, thereby ensuring the cleaning efficiency of the gearbox housing 12.

[0041] In this embodiment, the fixed housing 101 is barrel-shaped, and multiple through holes are provided on the peripheral surface of the fixed housing 101 to facilitate the clamping unit 1 to sink into the cleaning tank 3, and the cleaning liquid can quickly fill the fixed housing 101.

[0042] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
