Description

Technical Field

[0001] This utility model relates to the field of sleeve technology, and in particular to a composite device for cleaning the edge of a sleeve. Background Technology

[0002] Currently, the removal of rubber gaskets is all done manually. For residual parts, cleaning is done with a manual scraper or other sharp tools. For some sleeve-type components with end caps, the end cap and the cylinder are screwed together. To ensure the connection is sealed, a rubber gasket is added between the cylinder and the end cap. The rubber gasket is usually placed in a groove on the inner wall of the sleeve part to prevent the position of the rubber gasket from shifting during screwing. Before reassembling the disassembled component, the rubber gasket needs to be replaced. Manual removal of rubber gaskets is not conducive to the automation of the process. In addition, because there is a groove for the installation of the rubber gasket and the rubber gasket is very sticky, conventional brushes cannot effectively clean it and cannot meet the requirements for reuse. Moreover, the rubber gasket is deformed by the screwing process and the compression during use. After disassembly, the rubber gasket is stuck to the cylinder. During the removal of the rubber gasket, local tearing occurs and some residue remains in the groove. Therefore, this utility model proposes a composite device for cleaning the edge of the sleeve. Utility Model Content

[0003] The purpose of this invention is to provide a composite device for cleaning the edge of a sleeve, so as to solve the problems mentioned in the background art.

[0004] The present invention relates to a composite device for cleaning the edge of a sleeve, comprising a spline shaft, a bearing at the bottom of the spline shaft, a washer at the bottom of the bearing, a spring at the bottom of the washer, and a cover plate at the bottom of the spring.

[0005] In one embodiment, the bottom of the cover plate is provided with a cutter disc, and the outer edge of the cutter disc is provided with a scraper.

[0006] In one embodiment, the outer edge of the scraper is provided with a set screw.

[0007] In one embodiment, the bottom of the cutter head is provided with a spline sleeve, and the bottom of the spline sleeve is provided with a bottom cutter head.

[0008] In one embodiment, the assembly consisting of the cover plate, cutter head, set screw, spline sleeve, and scraper moves parallel to each other on the spline shaft, and the bottom cutter head is connected and fixed to the spline shaft through an expansion sleeve.

[0009] The beneficial effects provided by this utility model are:

[0010] 1. For intact rubber pads, a two-stage cleaning method is used: first, use the bottom blade to remove most of the rubber pad, and then use a scraper to clean the root.

[0011] 2. The spline joint enables synchronous floating and rotation of the cleaning device;

[0012] 3. The floating assembly structure allows for adaptive adjustment of the workpiece height when the main unit presses down at a constant height, ensuring close contact between the scraper and the workpiece without the need to control different pressing heights each time.

[0013] 4. The scraper is fixed with screws, which can be adjusted appropriately to fit different workpiece sizes. At the same time, the scraper is a separate part, which is convenient for later maintenance and replacement.

[0014] 5. By replacing the scraper with different materials, the protection requirements of workpieces made of different materials can be met;

[0015] 6. By replacing different springs, different cleaning pressures can be achieved. Attached Figure Description

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments of the present invention can be combined with each other. The technical solutions of the present invention will be further described below with reference to the accompanying drawings of the embodiments. The present invention is not limited to the specific embodiments described below.

[0021] It should be understood that the same or similar reference numerals in the accompanying drawings of the embodiments correspond to the same or similar components. In the description of this utility model, it should be understood that if terms such as "upper," "lower," "front," "rear," "left," "right," "top," and "bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms describing positional relationships in the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0022] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 As shown, a composite device for cleaning the edge of a sleeve includes a spline shaft 1, a bearing 2 at the bottom of the spline shaft 1, a washer 3 at the bottom of the bearing 2, a spring 4 at the bottom of the washer 3, a cover plate 5 at the bottom of the spring 4, a cutter disc 6 at the bottom of the cover plate 5, a scraper 7 at the outer edge of the cutter disc 6, a set screw 10 at the outer edge of the scraper 7, a spline sleeve 8 at the bottom of the cutter disc 6, and a bottom cutter head 9 at the bottom of the spline sleeve 8. The assembly consisting of the cover plate 5, the cutter disc 6, the set screw 10, the spline sleeve 8, and the scraper 7 moves parallel to each other on the spline shaft 1. The bottom cutter head 9 is connected and fixed to the spline shaft 1 by an expansion sleeve.

[0023] Combining manual cleaning with the following steps, large pieces are first removed, followed by cleaning the root area using a manual scraper or other sharp tools. A large-diameter blade, similar in diameter to the workpiece (sleeve), removes most of the rubber. The remaining residue is then cleaned at the root using a custom scraper mounted on the blade. Considering both thorough root cleaning and protection of the workpiece, if the workpiece is placed too low, insufficient downward pressure will result in incomplete removal of residual rubber. Conversely, if the workpiece is placed too high, excessive downward pressure may cause over-cutting. Therefore, the composite tool design incorporates a spring-floating function, ensuring the scraper maintains a consistent cutting pressure during the cleaning process to meet the cleaning requirements.

[0024] Installed on the main unit (power assembly), it enables automated cleaning of the rubber pads. Combined with front-end and back-end automated equipment, it achieves full-process automation. It adopts a process of one pressing down and two cleanings, which reduces the wear of the root cleaning scraper and improves its service life. The floating mechanism design facilitates automated control, eliminating the need to judge the precise height of the workpiece each time, and can adaptively adjust within a certain range. The modular design allows for adaptive adjustment by replacing some parts to meet different needs, without the need for complete replacement, and also facilitates later maintenance.

[0025] This composite device, as an accessory, can be used in cleaning machines or automated components. When used in cleaning machines, it combines with the machine's automatic moving and positioning mechanisms to place the workpiece in the positioning mechanism. The moving mechanism then drives this composite device to move, while simultaneously providing rotational power to achieve workpiece cleaning. When used in automated components, such as when matched with an industrial robot, the composite device provides rotational power, and the industrial robot grasps the workpiece and executes a fixed motion path to complete the workpiece cleaning.

[0026] Working Principle: The main unit (power assembly) and splined shaft 1 are fitted with a keyway end and fixedly connected to the main unit via bearing 2. Splined shaft 1 and splined sleeve 8 are a standard spline pair. The rotational power of the main unit can be transmitted to splined sleeve 8, allowing the assembly consisting of cover plate 5, cutter head 6, set screw 10, splined sleeve 8, and scraper 7 to rotate. The scraper is fixed with set screw 10, and its extension length can be adjusted appropriately according to the actual workpiece to meet the needs of different specifications. Considering the variation in workpiece placement height, when the workpiece is high or low, the spline pair structure allows the assembly to float up and down to adapt to the workpiece while maintaining a consistent pressing height. Spring 4 and washer 3 are added to keep the cutting pressure within a certain range, achieving root clearing while protecting the workpiece from overcutting. The diameter of the bottom cutter head is close to the inner diameter of the workpiece and is installed at the bottom of splined shaft 1 via an expansion sleeve. During the overall pressing process, it contacts the workpiece first, removing most of the rubber pad.

[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0028] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
