Description

Technical Field

[0001] The present invention relates to the technical field of sleeves, and in particular to a composite device for cleaning the edge of a sleeve and a use method thereof. Background Art

[0002] At present, the work of removing the rubber pad is all done manually. The remaining part is cleaned by a manual scraper or other sharp tools. At the same time, for some sleeve-type components with end covers, the end cover and the cylinder are screwed together. In order to ensure the sealing of the connection, a rubber pad is added between the cylinder and the end cover. The rubber pad is generally placed in a groove on the inner wall of the sleeve part to avoid the position of the rubber pad from being offset during the screwing process. Before the disassembled component is reassembled, the rubber pad needs to be replaced. Manual removal of the rubber pad is not conducive to realizing process automation. In addition, due to the existence of the rubber pad installation groove and the high viscosity of the rubber pad, a conventional brush cannot effectively clean the root and cannot meet the requirements for reuse. In addition, the rubber pad is extruded and deformed during the thread tightening process and the use process. After disassembly, the rubber pad is adhered to the cylinder. During the removal of the rubber pad, local tearing will occur and part of it will remain in the groove. Therefore, the present invention proposes a composite device for cleaning the edge of the sleeve. Summary of the invention

[0028] Combined with the manual cleaning process, first remove the large pieces, and then use a manual scraper or other sharp tools to complete the root cleaning; use a large-diameter cutter head close to the workpiece (sleeve) to remove most of the rubber, and use a customized scraper installed on the upper part of the cutter head to clean the remaining residue; Considering the complete cleaning of the root and the protection of the workpiece body, when the workpiece is placed too low, the downward pressure distance will be insufficient and the residual rubber cannot be completely cleaned; when the workpiece is placed too high, the downward pressure will be too large, which may easily cause overcutting of the workpiece body. The composite tool is designed with a spring floating function, which can enable the scraper to maintain a certain cleaning cutting pressure during the cleaning process to meet the cleaning requirements;

[0029] Installed on the main machine (power component), it can realize automatic cleaning of the rubber pad. Combined with the front and back end automation equipment, it realizes full process automation. The process of one-time pressing and two-time cleaning is adopted to reduce the wear of the root cleaning scraper and increase the service life. The floating mechanism design is convenient for automatic control. There is no need to judge the precise height of the workpiece every time. It can be adaptively adjusted within a certain range. The modular design can be adaptively adjusted by replacing some parts according to different needs. There is no need to replace the whole part, which is also convenient for later maintenance.

[0030] This composite device can be used as an accessory in a special cleaning machine or an automated component. When used in a special cleaning machine, the workpiece is placed on the positioning mechanism in combination with the automatic moving mechanism and positioning mechanism of the special machine. The moving mechanism drives the composite device to move and provides rotational power to achieve workpiece cleaning. When used in an automated component, if matched with an industrial robot, the composite device is provided with rotational power, and the industrial robot grabs the workpiece and executes a fixed motion path to complete the workpiece cleaning.

[0031] A method for using a composite device for cleaning a sleeve edge comprises the following steps:

The scraper is fixed with the set screw 10, and the extension length can be appropriately adjusted according to the actual workpiece to meet the requirements of workpieces of different specifications;

[0034] S3: Considering the change of workpiece placement height, when the workpiece is high or low, under the condition that the main machine presses down at the same height, the spline substructure is used to realize the floating requirement of the assembly part, and the workpiece is adapted to increase the spring 4 and the washer 3 to keep the cutting pressure within a certain range, which can not only realize the root cleaning, but also protect the workpiece from overcutting;

[0035] S4: The diameter of the bottom cutter head is close to the inner diameter of the workpiece. It is installed at the bottom of the spline shaft 1 through an expansion sleeve. During the overall downward pressure process, it first contacts the workpiece and can remove most of the rubber pads.

The spline shaft 1 and the spline sleeve 8 are standard spline pairs. The rotational power of the host can be transmitted to the spline sleeve 8, and the combination consisting of the cover plate 5, the cutter head 6, the set screw 10, the spline sleeve 8 and the scraper 7 can be rotated. The scraper is fixed with a set screw 10, and the extension length can be adjusted appropriately according to the actual workpiece to meet the needs of workpieces of different specifications. Considering the change in the placement height of the workpiece, when the workpiece is high or low, when the main machine is pressed down at the same height, the spline pair structure is used to realize the floating demand of the assembly part up and down, and the workpiece is adapted to increase the spring 4 and the washer 3, so that the cutting pressure is kept within a certain range, which can not only achieve root cleaning, but also protect the workpiece from overcutting. The diameter of the bottom cutter head is close to the inner diameter of the workpiece, and it is installed at the bottom of the spline shaft 1 through the expansion sleeve.
