Description

Technical Field

[0001] Embodiments of the present invention relate to the technical field of wheel cleaning devices, and specifically, to a wheel cleaning device for automotive parts. Background Art

[0002] In the process of wheel production, generally, the wheel blanks are first subjected to cutting processing, and then the turned wheels are cleaned, degreased, and deoiled, and finally painted; among them, when cleaning the wheels, generally, a through-type cleaning device is used to clean the wheels first. The conveying mechanism suspended at the top inside the channel drives several wheels to pass through the channel at one time, and the cleaning nozzles and drying nozzles on the inner side walls of the channel clean and then dry the wheels.

[0003] At present, the conveying mechanism in the through-type cleaning device generally includes a driving chain, a guide rail, and hooks. The hooks can smoothly move on the guide rail under the driving action of the driving chain, drive the wheels suspended thereon to move in the channel, and sequentially pass through components such as cleaning nozzles and drying nozzles.

[0004] However, the above structure has the following drawbacks: The hooks are usually slidably connected to the single guide rail through the pulleys at their tops, which means that during the movement, the wheels are easily swayed back and forth under the action of the sprayed cleaning liquid or wind force, resulting in poor overall stability and shortening the service life of the components; in addition, to ensure that both sides of the cylindrical wheels can fully receive the action of the nozzles on the two inner side walls of the channel to clean and dry the wheels, several wheels are arranged in sequence with their radial directions parallel to the conveying direction, resulting in a large space occupied in the conveying direction. Summary of the Invention

[0005] To overcome the above defects, embodiments of the present invention provide a wheel cleaning device for automotive parts, which solves the technical problem that in the related art, when using a traditional hook-type conveying mechanism in the cleaning device, during the movement, the wheels are easily affected by external forces and sway back and forth, resulting in poor overall stability and shortening the service life of the components.

[0006] According to one aspect, at least one embodiment of the present invention provides a wheel cleaning device for automotive parts, for conveying and cleaning wheels, including: A frame, on which a cleaning member is provided; Several suspension frame groups, several of the suspension frame groups are arranged in sequence along the wheel conveying direction, and each suspension frame group is slidably connected to the frame, and is used to support and drive the wheels to pass through the cleaning member, so that the cleaning member cleans the wheels. The suspension frame group includes: A suspension, the suspension is slidably connected to the frame. The suspension has two sliding connection points, and the two sliding connection points are respectively located on both sides of the wheel hub along the wheel hub conveying direction. The connecting line direction of the two sliding connection points is set at an angle with the wheel hub conveying direction, and the suspension can prevent the wheel hub from shaking.

[0007] For example, in a wheel hub cleaning device for automotive parts provided by at least one embodiment of the present invention, a support shaft is detachably provided on the suspension. The support shaft is used to penetrate and support the wheel hub, and the length direction of the support shaft is set at an angle with the wheel hub conveying direction to reduce the occupied space of the wheel hub in the conveying direction.

The support shaft penetrates through the two vertical rods and can support the wheel hub between the two vertical rods.

[0009] For example, in a wheel hub cleaning device for automotive parts provided by at least one embodiment of the present invention, a rubber sleeve for inserting into the process hole of the wheel hub is fixedly sleeved on the support shaft. The support shaft can rotate relative to the vertical rod to drive the wheel hub to rotate, so that the cleaning part can evenly clean the wheel hub.

[0010] For example, in a wheel hub cleaning device for automotive parts provided by at least one embodiment of the present invention, a rack along the wheel hub conveying direction is provided on the side wall of the frame. The suspension group further includes: A support plate, the support plate is slidably connected to the side wall of the frame; An engaging member, the engaging member is provided on the support plate and is used to drive the support shaft to rotate. The engaging member meshes with the rack and is detachably connected to one end of the support shaft.

[0011] For example, in a wheel hub cleaning device for automotive parts provided by at least one embodiment of the present invention, the engaging member includes: A gear, the gear is rotatably arranged on the support plate and meshes with the rack. The gear has a bevel gear part; A bevel gear, the bevel gear is rotatably arranged on the support plate and meshes with the bevel gear part, and one end of the support shaft is detachably connected to the bevel gear.

[0012] For example, in a wheel hub cleaning device for automotive parts provided by at least one embodiment of the present invention, a rotary track and two groups of guide rails are provided on the frame. The rotary track is used to receive the suspension group on one of the groups of guide rails. The suspension group can sequentially slide over one of the groups of guide rails, the rotary track and the other group of guide rails. The rotary track is configured to rotate and then introduce the suspension group on one of the groups of guide rails onto the other group of guide rails.

[0013] For example, in a wheel hub cleaning device for automotive parts provided by at least one embodiment of the present invention, two sets of the guide rails are arranged at a horizontal interval and crosswise, the rotary rail is located between the two sets of the guide rails, and the rotary rail and each set of the guide rails each include: Two tracks, the two tracks are symmetrically arranged and parallel to each other, and a conveyor belt is cyclically provided on each of the tracks. Wherein, two sliding connection points are provided at the top of the suspension, support blocks are provided on both of the two sliding connection points, the two support blocks abut against the conveyor belt, and the support blocks can move along the track under the cyclic action of the conveyor belt, so that the suspension frame group slides past one set of the guide rails, the rotary rail and the other set of the guide rails in sequence.

[0014] For example, in a wheel hub cleaning device for automotive parts provided by at least one embodiment of the present invention, the rotary rail further includes: A support bar, the support bar is fixedly arranged at the bottom of the track of one of the rotary rails for supporting the support plate, and the rotary rail is configured to drive the support bar to correspond to the support plate of the suspension frame group on one set of the guide rails after rotation, so that the rotary rail can receive the suspension frame group.

[0015] For example, in a wheel hub cleaning device for automotive parts provided by at least one embodiment of the present invention, two sliding connection points are provided at the top of the suspension, pulleys are rotatably provided on both of the two sliding connection points, and two slide rails along the wheel hub conveying direction are provided on the frame, and the two pulleys are respectively slidably connected to the two slide rails in a one-to-one correspondence.

[0016] The beneficial effects of the embodiments of the present invention are as follows: In this solution, the suspension of the suspension frame group is slidably connected to the frame in the form of two sliding connection points arranged along the conveying direction and offset front and back, and the two sliding connection points are respectively located on the left and right sides of the wheel hub along the conveying direction, forming a fixed suspension structure that intersects the wheel hub conveying direction. Compared with the single-guide-rail single-point sliding connection in the traditional suspension structure, it can better prevent the wheel hub from shaking during movement, thereby improving the overall stability, extending the service life of components, and also being able to adaptively change the cleaning angle of the cleaning part (spray head) to ensure that both sides of the wheel hub are fully subjected to the cleaning effect.

Detailed implementation manners

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention.

[0021] In order to simplify the drawings, only the parts related to the disclosure are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0022] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0024] In the description of this embodiment, terms such as "up", "down", "left", and "right" and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0025] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0026] like Figures 1 to 4As shown, it shows a cleaning device for a wheel hub 1 in an embodiment of the present invention, which is used to convey and clean the wheel hub 11. The frame 2 serves as an overall support structure to provide stable support for various components thereon, including cleaning parts in the form of cleaning nozzles installed thereon. By adjusting the spraying angle of the cleaning nozzles, it is ensured that several wheel hubs 1 conveyed therein are comprehensively cleaned.

[0027] Furthermore, to solve the shaking problem caused by the single-point sliding connection of the single guide rail 7 in the traditional suspension conveying structure, because most use pulley connections, it is easy to generate swinging along the conveying direction, and after all, the pulley cannot achieve ultra-precise sliding fit with the frame 2 to avoid swinging in the non-conveying direction, so it is very difficult to solve the above problems by changing the sliding connection structure; therefore, this solution directly changes the single-point sliding connection of the single guide rail 7 to a double-point sliding connection of the double guide rail 7, and further sets the double-point connection line to cross the conveying direction. Specifically, two sliding connection points 302 slidingly connected to the frame 2 can be provided at the top of the suspension 301. The two points are respectively located on the left and right sides of the wheel hub 1 along its conveying direction, and the connection line between the two points is arranged at an angle with its conveying direction. Furthermore, the entire suspension 301 can form an overall stable conveying structure that crosses the conveying direction. Therefore, regardless of the sliding connection structure used, when the suspension 301 is subjected to external forces along the conveying direction or non-conveying direction, it can remain stable, enabling the wheel hub 1 supported on the suspension frame group 3 to move stably on the frame 2, and thus can stably pass through the channel-type frame to comprehensively receive the cleaning action of the cleaning parts in the form of nozzles on its inner wall.

[0028] Among them, the suspension frame group 3 stably supports the wheel hub 1 to avoid that even if the suspension 301 of the suspension frame group 3 is stable, but if the form of using a hook to hook the edge of the wheel hub 1 is used to achieve conveying, the problem still cannot be fundamentally solved; specifically, a bracket can be welded or integrally formed at the bottom of the suspension 301. The bracket can be in the form of a flat wire mesh or an arc-shaped wire mesh that matches the contour of the wheel hub 1 to ensure that the wheel hub 1 can stand up and can comprehensively receive the cleaning action of the cleaning parts without being blocked by the bracket in contact with the wheel hub 1; or a fixture form can be used, which can better adapt to different specifications of the wheel hub 1 and directly fix and clamp parts such as the central process hole of the wheel hub 1 from both sides to ensure that the wheel hub 1 does not shift or shake during the conveying process, and the fixture preferably also has through holes for the cleaning liquid to pass through, so that the corresponding process hole parts can also be cleaned.

[0029] As Figure 2 shown, a support shaft 303 that can be penetrated and disassembled at the bottom of the suspension 301 is used to quickly pick up or place the wheel hub 1. The support shaft 303 can stably support the wheel hub 1 from the inside, improve stability, and can reduce the occlusion of various external parts of the wheel hub 1 to ensure the cleaning effect; finally, the axis of the support shaft 303 forms an angle with the conveying direction of the wheel hub 1. It has changed the traditional arrangement of the hubs 1 (a number of hubs 1 are arranged in sequence with their radial directions parallel to the conveying direction). The traditional arrangement takes up a large amount of space in the conveying direction. Now, after being arranged at an angle, the arrangement between the hubs 1 in the conveying direction is more compact, significantly reducing the space occupied by the hubs 1 in the conveying direction. As a result, more suspension frame groups 3 (each suspension frame group 3 can support more than one hub 1) can be arranged within the limited space of the frame 2, improving the working efficiency of the cleaning device and the processing capacity per unit time. At the same time, it will not affect the cleaning effect of the cleaning parts in the form of nozzles. Just change the position and angle of the cleaning nozzles accordingly.

[0030] As Figure 2 shown, through the cooperative design of the two vertical rods 304 at the bottom of the suspension 301 and the support shaft 303, a stable installation foundation is provided for both ends of the support shaft 303, forming a structure similar to a "door frame", which is also convenient for disassembly and installation. During installation, just pass the support shaft 303 through the corresponding holes of the vertical rods 304 to complete the assembly of the support shaft 303 and the suspension 301. The same applies when placing the hub 1. Place it between the two vertical rods 304. At the same time, it also greatly reduces the volume of the suspension 301. While reducing the weight, it also avoids blocking the cleaning effect of the cleaning parts on the hub 1. In addition, compared with a single support point, this two-point support method can effectively disperse the weight of the hub 1 and the external force generated during the cleaning process, reducing the risk of deformation of the support shaft 303 and ensuring the smoothness of the hub 1 conveying.

[0031] As Figures 2 to 3 shown, through the design of the rubber sleeve 4 and the rotatable support shaft 303, the cleaning process of the hub 1 is optimized. Specifically, the rubber sleeve 4 is inserted into the process hole of the hub 1, and it is tightly fitted with the process hole by using the elasticity of the rubber, which can not only firmly fix the hub 1 but also avoid scratches caused by direct metal contact. The support shaft 303 can rotate relative to the vertical rod 304, driving the hub 1 to rotate synchronously, so that the cleaning liquid sprayed by the cleaning parts can act evenly on each part of the hub 1, eliminating the cleaning dead corners and improving the cleaning quality and efficiency. At the same time, this structure is simple and practical, facilitating installation and maintenance. In addition, a ring groove for fixing the rubber sleeve 4 can be opened at the center position of the support shaft 303, and the support shaft 303 and the vertical rod 304 are connected by rotating parts such as bearings to achieve the relative rotation function.

[0032] As Figures 2 to 3As shown in the figure, in order to provide the power required for the rotation of the support rod at an angle to the conveying direction, this solution utilizes the cooperation of the rack 5, the engaging member 306 and the support plate 305. Specifically, the rack 5 is welded or bolted to the inner side wall of the frame 2. The engaging member 306 meshes with the rack 5 and is stably supported by the support plate 305. When the suspension frame group 3 moves along the conveying direction, the engaging member 306 rotates under the action of the rack 5, thereby driving the support shaft 303 and the hub 1 to rotate synchronously. No additional power source is required, which reduces costs and ensures the uniformity of cleaning. In addition, the engaging member 306 is detachably connected to the support shaft 303, which is convenient for replacement and maintenance.

[0033] The specific sliding connection form of the support plate 305 can adopt the cooperation of the slider and the guide rail 7. Install the slider on the support plate 305 and set the guide rail 7 on the side wall of the frame 2 to ensure smooth sliding. The engaging member 306 may take the form of a gear 3061, and the power is transmitted through the engagement of the teeth with the rack 5. A toothed transmission member, such as a toothed belt pulley, can also be used to form a similar meshing structure with the rack 5 to drive the support shaft 303 to rotate.

[0034] As Figures 2 to 3 As shown in the figure, finally, the power steering is realized by using the gear 3061 transmission structure, which solves the problem of power transmission with an included angle between the conveying direction and the rotation direction of the hub 1. Specifically, the gear 3061 meshes with the rack 5 arranged along the conveying direction of the hub 1, converting the linear motion of the suspension frame group 3 into the rotational motion of the gear 3061. The bevel gear part 3062 on it and the engaged bevel gear 3063 further change the transmission direction, enabling the support shaft 303 to drive the hub 1 to rotate, improving the cleaning effect. In addition, each component is rotatably connected to the support plate 305, and the frame 2 provides a stable support function to ensure the transmission stability during the movement. Moreover, the support shaft 303 and the bevel gear 3063 can be detachably connected by a pin shaft, which is convenient for maintenance and replacement.

[0035] Operation process: The suspension frame group 3 moves along the length direction of the rack 5 on the side wall of the frame 2. The gear 3061 meshes with the rack 5 and rotates. The bevel gear part 3062 coaxial with it on the gear 3061 rotates accordingly. The bevel gear 3063 engaged with the bevel gear part 3062 changes the transmission direction, transmitting the rotational power to the support shaft 303, and the support shaft 303 drives the hub 1 to rotate, improving the cleaning uniformity.

[0036] As Figures 5 to 6As shown, the above-mentioned stable conveying structure (suspension 301) has no problem during linear conveying. However, when faced with a situation where the conveying direction changes, it cannot adapt to the smooth turning sliding connection because the turning radii of the two sliding connection points 302 are inconsistent during turning, and the overall structure cannot be adjusted arbitrarily. Therefore, to solve the above problems, the cooperation of the rotary rail 6 and the two groups of guide rails 7 is set, that is, the linear rotary rail 6 with variable angle is used to realize the change of the conveying direction of the suspension frame group 3. The operation process is as follows: First, the suspension frame group 3 moves linearly along one of the guide rails 7 to the rotary rail 6. The rotary rail 6 rotates and corresponds to the other group of guide rails 7. Then, the suspension frame group 3 on the rotary rail 6 is introduced into the other group of guide rails 7, and this group of guide rails 7 continues to convey to complete processes such as cleaning and drying. It should be determined that both the rotary rail 6 and the guide rails 7 are linear to avoid the above problems. The rotation of the rotary rail 6 can be realized by the drive motor on the frame 2.

[0037] As Figures 7 to 9 shown, the two groups of guide rails 7 are spaced horizontally and intersect at an angle, which is convenient for the rotary rail 6 between them to transfer the suspension frame group 3. And the above structure is composed of two parallel and symmetric linear tracks 8 at intervals, and conveyor belts 9 are cyclically arranged on each track 8 to replace the conveying chain in the traditional structure because the conveying chain cannot adapt to the form of the rotary rail 6. Therefore, the cycle of the conveyor belt 9 is used to convey a part (support block 10) at the top of the suspension 301 abutting on it, thereby driving the overall stable linear movement of the suspension 301 to realize the suspension frame group 3 sliding past one of the linear guide rails 7, the linear rotary rail 6, and the other group of linear guide rails 7 in sequence.

[0038] Specifically, the track 8 can be a concave-shaped frame structure, which is convenient for the endless belt to circulate on its bottom edge, and is convenient for a part (support block 10) at the top of the suspension 301 to be stuck in the track 8 and abut on the endless belt, so that the endless belt stably conveys the suspension 301.

[0039] As Figures 5 to 6 、 Figure 10As shown, in order to prevent the support plate 305 and the engaging member 306 and other components that move with the suspension 301 from falling off or failing to complete subsequent actions smoothly when they rotate and change positions together with the suspension 301 on the input rotary rail 6, a support bar 11 is welded or integrally formed at the bottom of one of the tracks 8 of the rotary rail 6. When the rotary rail 6 receives the suspension frame group 3, the rotary rail 6 rotates to drive the support bar 11 to correspond to the support plate 305 of the suspension frame group 3 on the guide rail 7, so that the suspension frame group 3 can smoothly transition from the guide rail 7 to the rotary rail 6, and the support plate 305 and the engaging member 306 and other components that move with it are also stably connected to the support bar 11 to play a supporting role, thereby ensuring a stable receiving process; and after the angle adjustment of the rotary rail 6 is completed, the conveyor belt 9 on the rotary rail 6 continues to drive it to move to another group of linear guide rails 7, and the support plate 305 and the engaging member 306 and other components that move with it will be connected to the rack 5 of another group of linear guide rails 7 and the side wall of the frame 2.

[0040] Specifically, the support bar 11 can be the same in form and structure as the rack 5 and the side wall combination of the frame 2 to ensure that the entire process proceeds smoothly without any jamming. The bar design is also to avoid jamming during the process, which may result in the inability to drive the wheel hub 1 to rotate smoothly afterwards.

[0041] like Figure 11 As shown, if the entire production line adopts a linear rather than a circular form and does not involve turning, the above structure can be omitted and the traditional pulley 12 structure can be directly used. A rotating pulley 12 is set at the two sliding connection points 302 on the top of the suspension 301, and is slidingly connected to the two slide rails 13 on the frame 2 respectively. The pulley 12 rotates on the slide rail 13 to convert the sliding friction into rolling friction, so that the conveying process of the suspension frame group 3 is smoother.

[0042] Overall working process: the wheel hub 1 passes through the support shaft 303 and is supported between the two vertical rods 304 at the bottom of the suspension 301. The pulley 12 of the suspension frame group 3 slides on the slide rail 13 of the frame 2, driving the wheel hub 1 to pass through the cleaning nozzle and the drying nozzle on the inner wall of the frame 2 in turn. During the sliding process, since the two sliding connection points 302 are respectively located on both sides of the wheel hub 1 along the conveying direction, and the connecting line is at an angle to the conveying direction, the shaking of the wheel hub 1 under the impact of the cleaning liquid and the action of wind can be effectively limited, ensuring that the wheel hub 1 passes through the cleaning parts smoothly to complete the cleaning and drying processes.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
