Description

Technical Field

[0001] The invention relates to the field of cleaning equipment, in particular to equipment for treating metal oxide layers after welding. Background Art

[0002] For the welding of shafts, especially those with smaller diameters, it is difficult to make the weld scars produced during the welding process uniform and beautiful. In addition, oxide layers are easily produced near the weld scars. These oxide layers need to be removed, otherwise the corrosion resistance of the shafts will be easily affected.

[0003] When processing these oxide layers, it is necessary to use some cleaning brushes and cleaning wheels. During grinding, due to the irregular shape of the weld scar, when the shaft is fixed and then ground, it is easy for the contact between the cleaning tool and the weld scar to cause the shaft to have an axial movement tendency. If the fixing force is large, the force generated by these movement tendencies will act on the shaft body, which may easily cause the shaft to bend. If the fixing force is small, it is easy to cause movement, affecting the cleaning effect. Summary of the invention

The moving frame 52 is moved by the hydraulic cylinder 51, so that the shaft on the sprocket part 2 can be temporarily removed for cleaning. The movable frame 52 is provided with a support frame 6, and a cleaning brush structure 7 is provided above the support frame 6. The cleaning brush structure 7 includes a cleaning wheel 71. The cleaning wheel 71 is used to clean the metal oxide layer. The support frame 6 can hold up the shaft to facilitate the cleaning wheel 71 to clean the welding position; A reset wheel structure 8 is provided on the side of the movable frame 52, and the reset wheel structure 8 includes a mounting frame 81 and a reset wheel 82. The mounting frame 81 is fixedly mounted on the table frame 4, and the reset wheel 82 is mounted on the mounting frame 81 through a mounting frame 83. The reset wheel 82 can rotate with the shaft, and provide thrust and pulling force to the shaft through friction while rotating.

[0020] In this embodiment, the sprocket part 2 is provided with transport plates 21 arranged at equal intervals, and the transport plates 21 are provided with positioning grooves. The side walls of the transport plates 21 are provided with baffles 22, and the baffles 22 are used to block the metal shaft during the transportation of the metal shaft. A limit plate 23 is provided under the sprocket part 2, and the limit plate 23 is installed on a fixed base 24, and the fixed base 24 is fixedly installed on the table frame 4. When the transport plate 21 rotates with the sprocket part 2, the shaft can be removed from the feeding part 1, and during transportation, the baffle 22 can be used to prevent the shaft from falling off. The limit plate 23 can provide a limit from the bottom of the chain to prevent the chain from falling off under gravity and affecting the normal transportation of the shaft.

[0021] In this embodiment, the movable frame 52 includes a fixed seat 521, a slide rail 522, and a sleeve frame 523. The fixed seat 521 is fixedly installed on the top of the push rod 53, the slide rail 522 is installed on the fixed seat 521, and the sleeve frame 523 is installed on the slide rail 522 and is sleeved on the outer side of the sprocket part 2. The sleeve frame 523 can slide on the slide rail 522.

[0022] In this embodiment, a connecting plate 531 is connected to the inner wall surface of the pushing rod 53, and the connecting plate 531 is connected to the guide rail 532. The guide rail 532 is fixedly mounted on the rail plate 533, and the rail plate 533 is fixedly mounted on the table frame 4 through a connecting bracket 535. The pushing rod 53 can push the movable frame 52 to move upward. When moving upward, the support frame 6 can lift the shaft so that the shaft is lifted from the transport plate 21.

[0023] In this embodiment, the wedging structure 54 includes a wedging block 541, a crank 542, and a connecting rod 543. The wedging block 541 is fixedly installed on the outer side of the push rod 53. The bottom of the crank 542 is connected to the wedging block 541 through a wear-resistant wheel contact, and the top is rotatably connected to the connecting rod 543. The two ends of the connecting rod 543 are fixedly connected to the fixed seat 521 through a connecting seat. The wedging block 541 will push the crank 542 to rotate when following the push rod 53 to move upward, and will push the sleeve 523 to move horizontally through the connecting rod 543 when rotating, thereby causing the shaft to move horizontally to a position where the end can be structured with the reset wheel, thereby interacting with the reset wheel 82.

[0024] In this embodiment, the support frame 6 is connected to a supporting wheel group 61 via a connecting shaft. The supporting wheel group 61 lifts the shaft from the bottom and lifts it all the way to the upper end to contact the cleaning wheel 71 and the pressing wheel 72. Through the interaction of these wheel groups, the shaft is fixed on these wheel groups.

[0025] In this embodiment, the cleaning wheel 71 includes two symmetrically arranged parts with a gap between the two parts. The cleaning wheel 71 is provided with a groove, and the groove surface is provided with engaging teeth 711 and cleaning bristles. The shaft can be fixed by the engaging teeth 711, and the engaging also facilitates the shedding of the oxide layer. The cleaning bristles are made of materials such as steel wire, which can provide sufficient strength to clean the oxide layer.

[0026] In this embodiment, the cleaning brush structure 7 also includes a pressing wheel 72, a pressing fixed seat 73 and a fixed seat connecting plate 74. The pressing wheel 72 and the cleaning wheel 71 are arranged at both ends of the rotating shaft 75 and are respectively located on both sides of the pressing fixed seat 73. The pressing fixed seat 73 is fixedly mounted on the mounting frame 81 through the fixed seat connecting plate 74. The rotating shaft 75 is connected to the motor through a gear set. The pressing wheel 72 applies force to the shaft from top to bottom, and cooperates with the force of the supporting wheel group 61 to apply force to the shaft from both ends to facilitate the shaft to maintain balance.

[0027] In this embodiment, a pad 811 is provided on the outer side of the mounting frame 81 , and the pad 811 is installed at the bottom of the mounting frame 83 . The pad 811 facilitates the adjustment of the distance between the reset wheel 82 and the shaft end, and is more flexible to use.

[0028] In this embodiment, the reset wheel 82 includes two rows that are symmetrically arranged and staggered up and down. The angle between the symmetrical reset wheels is 90°, and the angle between the reset wheel 82 and the horizontal direction is 45°. In this way, when rotating, the symmetrical reset wheels 82 can provide thrust and pulling force respectively. At the same time, the friction force between the reset wheel 82 and the shaft end has a set upper limit. When the force generated by the movement trend of the shaft exceeds the friction force, the shaft will slide relative to the reset wheel 82, thereby alleviating the force on the shaft body.

[0029] Working principle: Place the welded shaft on the feed part 1, then remove the shaft from the feed part 1 and transport it backwards through the rotating sprocket part 2, and stop at the set position. At this time, start the hydraulic cylinder 51, and the movable frame 52 can be pushed up by the drive of the hydraulic cylinder 51. When moving up, the shaft can be lifted from the transport plate 21 by the provided support frame 6. At the same time, the wedge block 541 will push the crank 542 to rotate when following the push rod 53 to move up, and will push the sleeve 523 to move horizontally through the connecting rod 543 during rotation, so that the shaft to be processed moves horizontally with the sleeve 523 until the end of the shaft to be processed moves to contact with the reset wheel 82, and interacts with the reset wheel 82, and then the cleaning wheel 71 is rotated under the drive of the motor to clean the oxide layer. At this time, the shaft is driven to rotate, and the symmetrical reset wheel 82 can provide thrust and tension respectively during rotation to keep the position of the shaft stable.

Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
