Description

Technical Field

[0001] The utility model relates to a steel ball cleaning device, belonging to the technical field of cleaning devices. Background Art

[0002] Steel balls are key components of bearings. During the production process, the surface of steel balls will be stained and need to be cleaned. The traditional cleaning method is to place the steel balls on a sponge and then scrub them manually. This method is time-consuming and labor-intensive, and cannot guarantee that all the steel balls are cleaned. Therefore, there is also a method of using machines for cleaning in the existing technology.

[0003] For example, the Chinese utility model patent with authorization announcement number CN206676779U discloses a steel ball cleaning machine, which includes a frame, an inner cylinder provided on the frame, the inner cylinder being in the shape of a truncated cone with a small top and a large bottom, an outer cylinder being sleeved on the outer surface of the inner cylinder, the outer cylinder being in the shape of a hollow truncated cone, a gap being formed between the outer cylinder and the inner cylinder, and a sponge layer being provided on the inner wall of the outer cylinder and the outer wall of the inner cylinder. During use, the inner cylinder rotates continuously, and the steel ball enters the gap between the inner and outer cylinders from the top of the inner cylinder. A cleaning pipe on the frame sprays cleaning liquid into the gap, and the steel ball rotates and revolves under the action of the rotation of the inner cylinder. The sponges on the inner and outer cylinders clean the steel ball, and the steel ball continuously moves downward under the action of gravity, and is eventually discharged and falls onto a receiving tray below.

[0004] The above-mentioned steel ball cleaning machine greatly reduces the intensity of manual labor, improves work efficiency, and has a certain cleaning effect. However, it is only suitable for cleaning small balls less than one inch. The reason is that the large balls have a relatively large weight, resulting in a large impact force between the balls during the downward movement of the steel balls. This can easily cause damage to the surface of the steel balls, affecting the quality of the steel balls and, in turn, affecting the performance of the bearings. Utility Model Content

[0005] The purpose of the utility model is to provide a steel ball cleaning device to solve the problem that in the existing steel ball cleaning machine, when the steel balls are in use, they continuously move downward in the gap between the inner cylinder and the outer cylinder, resulting in that when cleaning larger steel balls, the steel balls are easily damaged due to their heavy weight and the collision force generated between the balls is also large, thereby affecting the quality of the steel balls.

[0006] In order to achieve the above purpose, the steel ball cleaning device in the present invention adopts the following technical solutions:

[0007] A steel ball cleaning device includes a horizontally arranged pair of cleaning rollers, the cleaning rollers include two parallel and spaced cleaning rollers, the two cleaning rollers are used to support the steel ball, and the steel ball cleaning device includes a rotating drive mechanism for driving at least one cleaning roller to rotate to drive the steel ball to rotate, a pressure bar is provided above the cleaning rollers, and the steel ball cleaning device also includes an intermittent drive mechanism for driving the pressure bar to move downward to contact the steel ball and rub the steel ball along the axial direction of the cleaning roller for a distance while pressing the steel ball downward, and then move upward and return to the initial position. The length of the pressure bar is sufficient to rub the steel ball from one end of the cleaning roller to the other end, and the pressure bar and each cleaning roller include a soft cleaning part for contacting the steel ball.

[0008] The beneficial effects of the above technical solution are: the utility model is a pioneering invention, and proposes a new steel ball cleaning device. When in use, the steel ball is placed on the cleaning roller pair and supported by the two cleaning rollers. The rotating drive mechanism drives at least one cleaning roller to rotate, thereby driving the steel ball to rotate, and the surface of the steel ball contacts and rubs with the soft cleaning part of the cleaning roller, which can clean the surface of the steel ball; at the same time, a pressure strip is provided above the cleaning roller pair. Under the action of the intermittent drive mechanism, the pressure strip can move downward to contact the steel ball, and while pressing the steel ball downward, it can rub the steel ball and roll a certain distance along the axial direction of the cleaning roller. This process not only realizes the forward conveying of the steel ball, but also the soft cleaning part of the pressure strip contacts and rubs with the steel ball, and the surface of the steel ball can be cleaned while driving the steel ball to roll, and the direction in which the steel ball is driven to rotate by the pressure strip is different from the direction in which the steel ball is driven to rotate by the cleaning roller, which can realize multi-directional cleaning of the steel ball. Then, under the action of the intermittent drive mechanism, the pressure bar moves upward and returns to its initial position. This process repeats. Combined with the length design of the pressure bar, the steel balls are rubbed from one end of the cleaning roller to the other, achieving thorough cleaning and discharge. At the same time, because the cleaning rollers are arranged horizontally, the steel balls cannot roll under their own weight without the pressure bar rubbing the steel balls. The multiple steel balls supported by the cleaning rollers can maintain a predetermined spacing between them, preventing collisions between the balls, avoiding damage to the steel ball surface, and ensuring the quality of the steel balls.

[0009] Furthermore, the intermittent driving mechanism includes driving wheels respectively arranged at both ends of the pressure strip, and the two ends of the pressure strip are respectively hinged to the driving wheels and form a parallelogram mechanism with the driving wheels.

[0010] Furthermore, the pressure strip also includes a hard pressing plate, the soft cleaning portion of the pressure strip is fixed on the lower surface of the hard pressing plate and has a length smaller than that of the hard pressing plate, and both ends of the hard pressing plate are respectively hinged to the driving wheels.

[0011] Furthermore, the soft cleaning portion of the layer is a plate-shaped sponge layer.

[0012] Furthermore, the rotation drive mechanism is used to drive the two cleaning rollers in the cleaning roller pair to rotate, and the two cleaning rollers have the same rotation direction.

[0013] Furthermore, the rotation speed of one of the cleaning rollers in the pair of cleaning rollers is greater than the rotation speed of the other cleaning roller.

[0014] Furthermore, the soft cleaning portion of the layer is a plate-shaped sponge layer.

[0015] Furthermore, the soft cleaning portion of the cleaning roller is a cylindrical sponge layer.

[0016] Furthermore, the cleaning roller further comprises a rigid roller, and the soft cleaning portion of the cleaning roller is wrapped and fixed on the outside of the rigid roller.

[0017] Furthermore, the steel ball cleaning device also includes a spraying device arranged above the cleaning roller pair and used for spraying a cleaning agent onto the steel balls. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In response to the technical problems existing in the prior art, the basic concept of the present invention is to provide a steel ball cleaning device that is completely different from the prior art. A horizontally arranged cleaning roller is used to support the steel ball and drive the steel ball to rotate. The intermittent pressure bar is used to rub the steel ball to roll forward, thereby achieving the steel ball transportation while ensuring the cleaning effect of the steel ball. The steel ball will not roll forward if the pressure bar does not rub it, thereby avoiding collision between the balls and causing surface damage.

[0023] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0024] Example 1 of the steel ball cleaning device in the utility model:

[0025] like Figure 1 and Figure 2As shown, the steel ball cleaning device includes a frame, on which a horizontally arranged pair of cleaning rollers is provided. The pair of cleaning rollers includes two parallel cleaning rollers 1 arranged at intervals. The interval between the two cleaning rollers 1 can meet the support requirements of a variety of steel balls 2 with different diameters. Therefore, the steel ball cleaning device of the present invention can be applied to both large balls and small balls, as long as the two cleaning rollers 1 can support the steel balls 2 (the steel balls 2 will not pass through the gap between the two cleaning rollers 1) and the highest point of the steel balls 2 is higher than the highest point of the two cleaning rollers 1. This requires a reasonable design of the spacing between the two cleaning rollers 1 based on the different diameters of the steel balls 2 to be cleaned. Of course, the two cleaning rollers 1 can also be designed to have an adjustable spacing. For example, a mounting seat is provided at both ends of each cleaning roller 1, and the mounting seat is fixed to the frame by bolts, and the spacing between the two mounting seats is adjustable.

[0026] The steel ball cleaning device also includes a rotational drive mechanism (not shown) for driving two cleaning rollers 1 to rotate in the same direction, thereby driving the steel ball 2 to rotate. Each cleaning roller 1 includes a soft cleaning portion for contacting the steel ball 2. As the steel ball 2 rotates, the soft cleaning portions of the two cleaning rollers 1 contact and rub against the surface of the steel ball 2, thereby cleaning the surface of the steel ball 2. Furthermore, the speed of one of the cleaning rollers in the cleaning pair is greater than the speed of the other cleaning roller. In this way, the cleaning roller with the higher speed drives the steel ball 2 to rotate, and rolling friction occurs between the two, while sliding friction occurs between the cleaning roller with the lower speed and the steel ball 2, thereby cleaning the surface of the steel ball 2 more thoroughly.

[0027] When the rotary drive machine is specifically set up, each cleaning roller 1 can be driven to rotate separately by an independent power source, for example, each cleaning roller 1 is equipped with a motor and a reducer. Of course, each cleaning roller 1 can also be driven to rotate by a set of power sources, for example, a drive gear is installed at the end of each cleaning roller 1, and a pair of transmission gears are provided between one cleaning roller and the other cleaning roller in the cleaning roller pair. The drive gear and the transmission gear are meshed, and the transmission ratio is not equal to 1. This not only realizes that power is transmitted from one cleaning roller to the other cleaning roller, but also makes the direction of the two cleaning rollers consistent, and at the same time, the two cleaning rollers can have different rotation speeds. Of course, more than two pairs of cleaning rollers can also be set up, so that more steel balls can be cleaned at one time, improving cleaning efficiency. The cleaning rollers with the same rotation speed in each pair of cleaning rollers can be driven to rotate by a set of drive systems, such as a sprocket chain system.

[0028] In this embodiment, the soft cleaning portion of the cleaning roller 1 is a cylindrical sponge layer. This sponge layer does not scratch the surface of the steel ball 1 and provides a good cleaning effect. Specifically, the cleaning roller 1 also includes a rigid roller. The cylindrical sponge layer is wrapped and fixed to the outside of the rigid roller. The rigid roller is easily mounted on the frame, and the aforementioned drive gear, sprocket, etc. are also easily mounted on the end of the rigid roller.

[0029] like Figure 1As shown, a pressure strip 3 is provided above the cleaning roller pair. The pressure strip 3 also includes a soft cleaning portion for contacting the steel ball 2. The steel ball cleaning device also includes an intermittent drive mechanism. Under the action of the intermittent drive mechanism, the pressure strip 3 can move downward to contact the steel ball 2. While pressing down on the steel ball 2, it can also rub the steel ball 2 along the axial direction of the cleaning roller 1 for a distance. This process not only realizes the forward conveyance of the steel ball 2, but also the soft cleaning portion of the pressure strip 3 contacts and rubs the steel ball 2, cleaning the surface of the steel ball 2 while driving the steel ball 2 to roll. The direction in which the steel ball 2 is driven by the pressure strip 3 is different from the direction in which it is driven by the cleaning roller 1, which can achieve multi-directional cleaning of the steel ball 2. Then, under the action of the intermittent drive mechanism, the pressure strip 3 moves upward and returns to its initial position. The length of the pressure strip 3 is sufficient to rub the steel ball 2 from one end of the cleaning roller 1 to the other end. Therefore, by controlling the reciprocating movement of the pressure strip 3 by the intermittent drive mechanism, the steel ball 2 can be thoroughly cleaned and automatically unloaded.

[0030] The intermittent drive mechanism controls the intermittent pressing and releasing of the pressure strip 3, ensuring that both large and small balls can be cleaned thoroughly. The large balls are heavier, creating a greater squeezing force with the cleaning roller 1, thus generating greater friction and making them easier to clean. However, the small balls are lighter, and the friction between them and the cleaning roller 1 is insufficient. At this time, the downward pressure of the pressure strip 3 increases the friction between the small balls and the cleaning roller 1, and also generates friction between the small balls and the pressure strip 3, thus ensuring the cleaning effect of the small balls.

[0031] At the same time, since the cleaning rollers are arranged horizontally, the steel balls 2 cannot roll forward by their own weight when the pressure strips 3 do not rub the steel balls 2. The multiple steel balls 2 supported by the cleaning rollers can maintain a predetermined distance between each other, and there will be no collision between the balls, which can avoid damage to the surface of the steel balls 2, ensure the quality of the steel balls 2, and thus ensure the performance of the bearings.

[0032] Specifically in this embodiment, Figure 2 As shown, the intermittent drive mechanism includes drive wheels 4 respectively arranged at both ends of the pressure strip 3, and the two ends of the pressure strip 3 are respectively hinged to the drive wheels 4, and the distances from the hinge points at both ends to the rotation centers of the corresponding drive wheels 4 are equal. At the same time, the spacing between the hinge points at both ends is equal to the spacing between the rotation centers of the two drive wheels 4, that is, the pressure strip 3 and the two drive wheels 4 form a parallelogram mechanism. When one of the drive wheels 4 rotates, it will drive the other drive wheel 4 to rotate, and the pressure strip 3 will produce a spatial translation movement. During this process, the pressure strip 3 gradually approaches the steel ball 2 until it contacts the steel ball 2, and then while pressing down the steel ball 2, it can rub the steel ball 2 to roll forward, and then the pressure strip 3 will move away from the steel ball 2 and reset to its initial position. The parallelogram mechanism is relatively simple in structure, convenient to manufacture and install, and has a good use effect.

[0033] In this embodiment, the soft cleaning portion of the bead 3 is a plate-like sponge layer 32. The steel ball 2 passes between the plate-like sponge layer 32 and the two cylindrical sponge layers, avoiding contact with any hard objects and ensuring it is not scratched. The bead 3 also includes a hard pressure plate 31. The plate-like sponge layer 32 is fixed to the lower surface of the hard pressure plate 31 and is shorter than the hard pressure plate 31. The length of the plate-like sponge layer 32 is sufficient to rub the steel ball 2 from one end of the cleaning roller 1 to the other. The two ends of the hard pressure plate 31 are hinged to the drive wheel 4, which facilitates assembly and allows replacement of the plate-like sponge layer 32 without removing the hard pressure plate 31 if it wears out.

[0034] In addition, Figure 1 As shown, the steel ball cleaning device also includes a spraying device 5 arranged above the cleaning roller and used to spray a cleaning agent onto the steel ball 2. The spraying device 5 is symmetrically arranged on both sides of the steel ball 2. The cleaning agent can be an oil or water-based cleaning agent to realize an automated cleaning operation.

[0035] Example 2 of the steel ball cleaning device in the utility model:

[0036] Different from Example 1, the intermittent drive mechanism is not a parallelogram mechanism. Figure 3 As shown, it is a combination of two linear drive mechanisms, one of which is arranged vertically and is defined as a vertical drive mechanism 6, and the other linear drive mechanism is arranged horizontally and is defined as a horizontal drive mechanism 7. The output end of the vertical drive mechanism 6 is fixedly connected to the pressure bar 3, and is used to drive the pressure bar 3 to move up and down. The output end of the horizontal drive mechanism 7 is fixed to the cylinder body of the vertical drive mechanism 6, and is used to drive the vertical drive mechanism 6 to move horizontally, thereby causing the pressure bar 3 to move horizontally. During use, the two linear drive mechanisms need to cooperate well. For example, the vertical drive mechanism 6 in the initial position is located at the rear position. In the initial stage, the vertical drive mechanism 6 works first, driving the pressure bar 3 to move downward until the pressure bar 3 contacts the steel ball 2. Then the horizontal drive mechanism 7 starts to work, controlling the vertical drive mechanism 6 and the pressure bar 3 to move forward synchronously, so as to achieve the goal of pressing the steel ball 2 while rubbing the steel ball 2 along the axial direction of the cleaning roller 1 for a distance. Then the vertical drive mechanism 6 works, driving the pressure bar 3 to move upward away from the steel ball 2. Finally, the horizontal drive mechanism 7 works, controlling the vertical drive mechanism 6 and the pressure bar 3 to move backward until they return to the initial position. This cycle can also achieve the same function as Example 1. Among them, the vertical drive mechanism 6 and the horizontal drive mechanism 7 can be hydraulic cylinders, air cylinders or electric push rods, and the cylinder body of the horizontal drive mechanism 7 needs to be fixed on the frame.

[0037] In other embodiments of the steel ball cleaning device, the spray device can also be arranged on a single side of the steel ball.

[0038] In other embodiments of the steel ball cleaning device: the steel ball cleaning device may not include a spray device, but the cleaning agent is manually added according to the cleaning situation.

[0039] In other embodiments of the steel ball cleaning device: the cleaning roller may not include a rigid roller, and the soft cleaning part of the cleaning roller is not a cylindrical sponge layer wrapped and fixed on the outside of the rigid roller. For example, the cleaning roller includes a sponge roller made of pure sponge material and in a cylindrical shape. Of course, for easy installation, a rigid fixing frame can be fixed at both ends of the sponge roller. The fixing frame includes a fixing plate and a mounting shaft fixed perpendicular to the fixing plate. The fixing plate can be bonded and fixed to the end face of the sponge roller. The mounting shaft is used to realize the rotational installation of the sponge roller and is used for transmission connection with the rotating drive mechanism.

[0040] In other embodiments of the steel ball cleaning device: when the cleaning roller includes a rigid roller, the cylindrical sponge layer can also be replaced by a cylindrical soft brush, and of course can also be replaced by cotton cloth.

[0041] In other embodiments of the steel ball cleaning device: when the pressure strip includes a hard pressure plate, the plate-shaped sponge layer can also be replaced by a plate-shaped soft brush, and of course can also be replaced by cotton cloth.

[0042] In other embodiments of the steel ball cleaning device: the pressure strip may not include a pressure plate with the soft cleaning portion fixed on the lower surface of the hard pressure plate, but may include a sponge strip made of pure sponge material. When a parallelogram mechanism in the form of drive wheels on both sides is adopted, a rigid fixing frame is fixed to each end of the sponge strip, one end of the fixing frame is bonded and fixed to the end face of the sponge strip, and the other end is hinged to the drive wheel. Of course, holes can also be directly punched at both ends of the sponge strip, and the hinge connection with the drive wheel can be directly achieved by passing a pin. When an intermittent drive mechanism in the form of a combination of two linear drive mechanisms is adopted, the pressure strip may have a hard pressure plate, and the output end of the vertical drive mechanism is fixedly connected to the hard pressure plate. Of course, the pressure strip may also not include a hard pressure plate, in which case the output end of the vertical drive mechanism is directly fixedly connected to the sponge strip.

[0043] In other embodiments of the steel ball cleaning device: the rotation speed and direction of the two cleaning rollers in the cleaning pair of rollers can be the same; of course, the directions can also be different. In this case, the rotation speeds of the two cleaning rollers must be different, otherwise the steel ball cannot be driven to rotate; of course, one of the cleaning rollers can rotate and the other cleaning roller cannot rotate. At this time, there is sliding friction contact between the non-rotating cleaning roller and the steel ball, and the contact point on the cleaning roller is always in the same position.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The scope of patent protection of the present invention shall be based on the claims. Any equivalent structural changes made using the description and drawings of the present invention shall also be included in the scope of protection of the present invention.
