[0030] See also Figure 3 , Figure 4 , Figure 6 and Figure 8 In order to ensure the circulation of external cleaning liquid, an opening is provided in the middle of the inner end of the cleaning brush 111, and the top of the external mounting sleeve 106 and the bottom of the fixed outer ring 109 are in a state of mutual contact; a sealing ring 108 is glued to the inner ring at the top of the external mounting sleeve 106, and the other end of the sealing ring 108 is in a state of contact with the bottom groove of the fixed outer ring 109; an opening is provided in the middle of the inner end of the cleaning brush 111 to facilitate the circulation of the upper and lower cleaning liquids. When the top of the external mounting sleeve 106 is squeezed against the bottom of the fixed outer ring 109, the top of the sealing ring 108 is just pressed into the corresponding groove of the bottom ring of the fixed outer ring 109 to improve the sealing of the connection.

[0031] See also Figure 4 , Figure 5 , Figure 6 , Figure 7 and Fig. 9In order to protect dirty water from splashing during the cleaning process, a protective component is provided between the cleaning cylinder sleeve 102 and the sewage discharge head 105. The protective component includes two sets of protective covers 2. The protective covers 2 are symmetrically sleeved on the front and rear ends of the cleaning cylinder sleeve 102. A guide port 201 is installed on the upper part of the rear end protective cover 2. The tops of the front and rear end protective covers 2 close to each other are correspondingly provided with outer sleeve plates 203. The outer sleeve plates 203 and the cleaning cylinder sleeve 102 are threadedly connected by bolts 204. Corresponding inner convex pads are provided between the outer sleeve plates 203 and the cleaning cylinder sleeve 102. 205, the inner convex pad 205 is glued to the lower part of the inner surface of the outer sleeve 203; the inner convex pad 205 is designed with rubber material, and the other end of the inner convex pad 205 is in a state of fitting with the outer wall of the cleaning sleeve 102; the grooves at the upper and lower openings of the front and rear end protective outer cover 2 are all glued with corresponding inner sealing pads 206, and the other end of the inner sealing pad 206 is in a state of being squeezed with the outer wall of the cleaning sleeve 102; when the cleaning sleeve 102 is rotated to wash the workpiece on the cleaning table 104, the cleaning liquid flows in the cleaning sleeve 102, and under the continuous water inflow, the sewage discharge device provided on the cleaning sleeve 102 is used to discharge the sewage. The sewage from the sewage head 105 is blocked by the protective outer cover 2 at both ends of the sewage head 105, that is, the outer ends of the cleaning sleeve 102, so that the inner sealing gaskets 206 at both ends are pressed against the outer wall of the cleaning sleeve 102, wherein the outer sleeve plate 203 and the protective outer cover 2 are an integrated structure, and the outer sleeve plate 203 and the cleaning sleeve 102 are threadedly connected by bolts 204 to complete the installation of the protective outer cover 2 as a whole, and the sewage splashing out of the sewage head 105 is blocked to avoid continuous splashing and affecting the work. After the cleaning is completed, the sewage rises to a side with a guide port 201. When the protective outer cover 2 is installed on the cleaning sleeve 102, an external pipe can be connected to it to draw it out; when the protective outer cover 2 is installed, the outer sleeve plate 203 is fitted on the outer wall of the cleaning sleeve 102, and the side of the outer sleeve plate 203 that contacts the cleaning sleeve 102 is glued with an inner convex pad 205 made of rubber, which can increase the friction of the contact surface between the outer sleeve plate 203 and the cleaning sleeve 102 to avoid slipping; when the protective outer covers 2 at both ends are matched and installed on the cleaning sleeve 102, the upper and lower ends of the corresponding cleaning sleeve 102 side are provided with inner sealing pads 206, which are pressed against the outer wall of the cleaning sleeve 102 to improve the sealing of the connection at the opening.

[0032] Working principle: First of all, the current traditional micro bearing inner ring cleaning device is mainly composed of a production area 1, a cleaning mechanism 101, a cleaning sleeve 102, a clamping mechanism 103 and a cleaning table 104. After the parts are produced, the clamping mechanism 103 brings the workpiece to the cleaning table. When it is under the cleaning sleeve 102, the pneumatic lifting structure arranged in the cleaning mechanism 101 and the motor drive the cleaning sleeve 102 to control the downward movement and rotation of the workpiece to press the workpiece on the cleaning table 104. The cleaning water source is connected to the cleaning sleeve 102 by the upper conduit of the cleaning mechanism. The cleaning water source contains cleaning liquid for brushing. When the cleaning brush 111 is damaged during long-term work, the cleaning brush 111 is designed to be detachable from the cleaning sleeve 102, wherein the cleaning sleeve 102 and the fixed outer ring 109 are integrated. The structure is designed that when the cleaning sleeve 102 rises, the cleaning brush 111 is rotated, wherein the cleaning brush 111 is in a connected state with the outer mounting sleeve 106, the outer mounting sleeve 106 is sleeved on the outside of the cleaning sleeve 102, and the outer mounting sleeve 106 is in a connected state with the threaded sleeve 107, wherein the threaded sleeve 107 is threadedly connected to the inner threaded groove 110. Under the action force, the outer mounting sleeve 106 can be driven to rotate, and the threaded sleeve 107 can be driven to move up and down in the inner threaded groove 110. When the threaded sleeve 107 is moved downward and the connection state between the threaded sleeve 107 and the inner threaded groove 110 is separated, the outer mounting sleeve 106 can be separated from the fixed outer ring 109, until the cleaning brush 111 is separated from the cleaning sleeve 102, and then it is removed. When the brush is damaged, it can be removed and replaced in time, which improves the convenience of replacement and also improves the cleaning effect.

[0033] When the cleaning sleeve 102 is rotated to wash the workpiece on the cleaning table 104, the cleaning liquid flows in the cleaning sleeve 102, and under the continuous water inflow, it flows out from the sewage discharge head 105 provided on the cleaning sleeve 102. At this time, protective outer covers 2 are symmetrically provided at the sewage discharge head 105, that is, at both ends of the outside of the cleaning sleeve 102, so that the inner sealing gaskets 206 at both ends are squeezed on the outer wall of the cleaning sleeve 102, wherein the outer sleeve plate 203 and the protective outer cover 2 are of an integrated structure design, and the outer sleeve plate 203 and the cleaning sleeve 104 are connected by bolts 204. The sleeve 102 is threadedly connected to complete the installation of the protective outer cover 2 as a whole, and to block the sewage splashing out of the sewage head 105. After the cleaning is completed, when the sewage rises to the end with the guide port 201, it can be extracted by an external pipe. If the bolt 204 is removed and the outer sleeve plate 203 is in a movable state, the protective outer cover 2 can be removed as a whole. The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
