Technical Field

[0001] The invention relates to the technical field of workpiece cleaning, and in particular to an internal cleaning device for producing a bellows compensator. Background Art

[0002] The bellows compensator is a retractable pipe connected between two pipes. Its side walls are mostly corrugated. During the processing of the bellows, some oil stains often adhere to it. The staff usually cleans the inner wall of the bellows. When cleaning, the staff often rotates the bellows at a uniform speed and moves the high-speed rotating brush column up and down to achieve the purpose of uniform cleaning.

[0003] However, when the current cleaning device cleans the bellows, it is not convenient to apply pressure between the bellows and the cleaning member, which results in insufficient cleaning of the bellows. In addition, the existing cleaning device is not convenient to repeatedly scrape off the oil stains attached to the cleaning member during cleaning, which results in the cleaning member not cleaning the inner wall of the bellows thoroughly enough, resulting in poor cleaning effect of the inner wall of the bellows.

Under the action of the brush column against the inner wall of the bellows, the movement of the sliding rod will squeeze the compression spring to cause the ring to apply pressure to the rotating support plate. The support plate will be pressurized to make the inner wall of the bellows fully contact with the brush column, thereby causing the brush column to brush the inner wall of the bellows more fully, thereby enhancing the cleaning effect.

[0012] 3. The rotation of the shaft sleeve will drive the two-way threaded sleeve to rotate. The rotation of the two-way threaded sleeve will drive the fixed frame and the scraper ring to move back and forth along the slide rod through the threaded block 2. The reciprocating movement of the scraper ring will repeatedly scrape off the oil stains attached to the brush column, so that the brush column is always kept clean. The brush column cleans the inner wall of the bellows thoroughly, making the cleaning more effective. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below with reference to specific diagrams.

[0025] Embodiment 1: An internal cleaning device for bellows compensator production, such as Figure 1-Figure 10 As shown, it includes a base 1, a slide groove is opened on the base 1, an outer frame 2 is welded on the base 1, a square hole is opened on one side of the outer frame 2, and a long hole is opened on the other side of the outer frame 2. A motor 3 is connected to the outer frame 2 by bolts, and the output shaft of the motor 3 is rotatably connected to the outer frame 2. A rotating mechanism is provided on the base 1, and a bellows 5 is placed on the rotating mechanism. A plurality of fixing holes are opened at both ends of the bellows 5. The rotating mechanism is used to slowly rotate the bellows 5, and a cleaning mechanism for cleaning the inner wall of the bellows 5 is provided on the outer frame 2.

[0026] The rotating mechanism includes a support plate 41, which is slidably connected to the slide groove of the base 1, and the support plate 41 is used to place the bellows 5. The support plate 41 is provided with a plurality of protrusions, and the plurality of protrusions of the support plate 41 are used to limit the bellows 5. The bellows 5 is placed on the support plate 41, and a plurality of fixing holes at the bottom of the bellows 5 are respectively sleeved on the plurality of protrusions of the support plate 41. A transmission wheel 1 42 is connected to the support plate 41 by bolts, and a bidirectional screw rod 43 is connected to one end of the output shaft of the motor 3 by bolts, and a transmission shaft 44 is welded to the bottom end of the bidirectional screw rod 43, and a transmission wheel 2 45 is connected to the bottom of the transmission shaft 44 by bolts, and the transmission wheel 2 45 is arranged in parallel with the transmission wheel 1 42, and a belt 1 46 is wound between the transmission wheel 2 45 and the transmission wheel 1 42, and the belt 1 46 passes through the outer frame 2.

[0027] The cleaning mechanism includes a sliding plate 61, which is slidably connected to the long strip hole of the outer frame 2, and a rotating sleeve 62 is rotatably connected to the sliding plate 61, and a square slide groove is opened on the rotating sleeve 62. The bottom end of the rotating sleeve 62 is connected to a brush column 63 by bolts, and a plurality of brushes are arranged on the outer side of the brush column 63. The brush column 63 passes through the outer frame 2, and the brush column 63 is used to brush the oil stains on the inner wall of the corrugated tube 5. A threaded block 64 is threadedly connected to the bidirectional screw rod 43, and the threaded block 64 is connected to one side of the sliding plate 61 by bolts. A prismatic shaft 65 is rotatably connected to the outer frame 2, and the prismatic shaft 65 is slidably connected to the direction slide groove of the rotating sleeve 62. A passive wheel 66 is connected to the prismatic shaft 65 by bolts, and a driving wheel 67 is connected to the output shaft of the motor 3 by bolts, and a belt 2 68 is wound between the driving wheel 67 and the passive wheel 66.

[0028] First, the staff places the bellows 5 on the support plate 41 so that the fixing hole of the bellows 5 is sleeved on the protrusion of the support plate 41. Then the staff starts the motor 3. The output shaft of the motor 3 rotates to drive the bidirectional screw rod 43, the driving wheel 67, the transmission shaft 44 and the transmission wheel 2 45 to rotate together. The transmission wheel 2 45 rotates through the belt 1 46 to drive the transmission wheel 1 42 to rotate, thereby driving the support plate 41 and the bellows 5 to rotate together. At the same time, the driving wheel 67 rotates through the belt 2 68 to drive the driven wheel 66 to rotate at high speed, thereby driving the prismatic shaft 65, the rotating shaft sleeve 62 and the brush column 63 to rotate at high speed. When the bidirectional screw rod 43 rotates, it will drive the sliding plate 61 to move downward first through the threaded block 1 64. The sliding plate 61 moves downward, which will drive the rotating sleeve 62 and the brush column 63 to move downward together. The rotating brush column 63 moves downward and brushes the oil stains on the inner wall of the bellows 5. Then the bidirectional screw rod 43 continues to rotate through the threaded block 64 to drive the sliding plate 61, the rotating sleeve shaft 62 and the brush column 63 to move upward together. Repeat this process. While the bidirectional screw rod 43 rotates, the sliding plate 61 is driven to move back and forth up and down through the threaded block 64, thereby driving the high-speed rotating brush column 63 to move back and forth up and down. At the same time, the bellows 5 rotates slowly, so that the brush column 63 evenly cleans the inner wall of the bellows 5. After cleaning, the staff turns off the motor 3 and removes the bellows 5 from the support plate 41.

[0029] Embodiment 2: Based on embodiment 1, Figure 2-Figure 9 As shown, it also includes a pressure mechanism, which is arranged on the sliding plate 61, and is used to apply pressure between the brush column 63 and the inner wall of the corrugated tube 5. The pressure mechanism includes an extrusion rod 71, and the two extrusion rods 71 ​​are respectively welded on both sides of the sliding plate 61. A sliding limit rod 72 is slidably connected to the square hole of the outer frame 2, and the upper parts of both sides of the sliding limit rod 72 are provided with inclined surfaces. The two extrusion rods 71 ​​are respectively in contact with the two sides of the sliding limit rod 72, and the extrusion rod 71 is respectively in contact with the two sides of the sliding limit rod 72. 1 is used to squeeze the inclined surface of the sliding limit rod 72, the support plate 41 is sleeved with a collar 73, the collar 73 is used to press the corrugated tube 5, the collar 73 is welded with a limit column 74 on the side close to the outer frame 2, the limit column 74 is slidably connected with a sliding rod 75, a compression spring 76 is connected between the sliding rod 75 and the limit column 74, a connecting rod 77 is welded between the sliding rod 75 and the sliding limit rod 72, and the connecting rod 77 and the sliding rod 75 both pass through the outer frame 2.

[0030] When the brush column 63 contacts the inner wall of the bellows 5, the extrusion rod 71 moves downward to squeeze the inclined surface of the sliding limit rod 72, thereby causing the sliding limit rod 72 to drive the connecting rod 77 and the sliding rod 75 to move in the direction close to the bellows 5. Under the action of the brush column 63 against the inner wall of the bellows 5, the movement of the sliding rod 75 will cause the ring 73 to apply pressure to the rotating support plate 41 by squeezing the compression spring 76. The support plate 41 will be pressurized to make the inner wall of the bellows 5 fully contact with the brush column 63, thereby causing the brush column 63 to brush the inner wall of the bellows 5 more fully, thereby enhancing the cleaning effect of the bellows 5. The extrusion rod 71 moves upward and no longer squeezes the sliding limit rod 72. The compression spring 76 resets and drives the sliding rod 75, the connecting rod 77 and the sliding limit rod 72 to reset together.

[0031] Embodiment 3: Based on embodiment 2, Figure 2-Figure 10 As shown, it also includes a scraping mechanism, which is arranged on the sliding plate 61, and is used to scrape off the oil stains attached to the brush column 63. The scraping mechanism includes a sliding rod 81, and the sliding rod 81 is welded to the bottom of the sliding plate 61. A two-way threaded sleeve 82 is welded to the outside of the rotating sleeve 62, and a thread block 2 83 is threadedly connected to the two-way threaded sleeve 82. A fixing frame 84 is bolted to the outside of the thread block 2 83, and the fixing frame 84 is slidably connected to the sliding rod 81. A scraping ring 85 is welded to the bottom of the fixing frame 84, and the scraping ring 85 is sleeved on the brush column 63. The scraping ring 85 is used to scrape off the oil stains on the brush column 63.

[0032] When the shaft sleeve 62 is rotated, the bidirectional threaded sleeve 82 will be driven to rotate. The rotation of the bidirectional threaded sleeve 82 will drive the fixing frame 84 and the scraper ring 85 to move downward along the slide rod 81 through the second threaded block 83. The downward movement of the scraper ring 85 will scrape off the oil stains attached to the brush column 63. Then, the bidirectional threaded sleeve 82 continues to rotate, which will cause the scraper ring 85 to move upward through the second threaded block 83 and the slide rod 81. Repeat this process. The rotation of the bidirectional threaded sleeve 82 will drive the fixing frame 84 and the scraper ring 85 to move back and forth up and down along the slide rod 81 through the second threaded block 83. The up and down reciprocating movement of the scraper ring 85 will repeatedly scrape off the oil stains attached to the brush column 63, thereby keeping the brush column 63 in a clean state at all times, and then the brush column 63 cleans the inner wall of the bellows 5 thoroughly, thereby making the cleaning more effective.
