Description

Technical Field

[0001] This invention relates to the field of shaft parts cleaning technology, and more specifically to a shaft parts cleaning device. Background Technology

[0002] Shafts are a common type of hardware component, primarily used to support transmission parts, transmit torque, and bear loads. They can be categorized as solid shafts or hollow shafts. After machining, shafts often retain oil residue, necessitating cleaning. Currently, cleaning typically involves placing the shafts in a cleaning tank and then manually washing them, resulting in low efficiency and high labor intensity. Furthermore, when cleaning multiple shafts, it's crucial to prevent impacts that could damage their surfaces, making the cleaning process cumbersome. Summary of the Invention

[0003] The purpose of this invention is to provide a cleaning device for shaft parts, which can effectively solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A shaft-type parts cleaning device includes a cleaning tank, in which a support component is provided. Multiple shaft-type parts are placed on the support component and positioned by a positioning component. A transmission mechanism then drives the shaft-type parts on the support component to move. The supporting assembly includes a supporting plate with a cleaning hole on its upper surface, fixed legs distributed at its bottom, a fixed end plate and a sliding end plate at each end, a rolling wheel at the bottom of the fixed legs, a guide plate on its outer side wall, one end of the guide plate being placed in the guide groove of a fixed guide rail, the fixed guide rail being placed on the inner wall of the cleaning tank, a limiting groove being formed on one side wall of the fixed end plate, a limiting slide groove being formed on the sliding end plate, a fixed pad being connected to one side wall, the supporting plate passing through the limiting slide groove and the two outer side walls of the supporting plate respectively abutting the two inner side walls of the limiting slide groove, the sliding end plate moving along the length of the supporting plate until one end of the shaft part extends into the limiting groove and abuts against the inner wall of the limiting groove, the other end being supported on the fixed pad and pressed against the sliding end plate, the fixing assembly fixing the sliding end plate to the supporting plate; The fixing assembly includes an adjusting screw, a fixing block, a limiting guide post, and a positioning block.

The first reset spring pushes the spring baffle to move until one end of the limiting guide post passes through the second through hole and the first through hole in sequence and the spring baffle abuts against the adjusting screw. Rotating the adjusting screw causes the adjusting screw to push the spring baffle and the limiting guide post to move until the limiting guide post abuts against the bottom of the guide groove. When the adjusting screw is rotated further, the limiting guide post stops linear movement and the fixed pressure block moves toward the bearing plate until the pressing plate presses against the side wall of the bearing plate.

[0005] Preferably, the positioning assembly includes a fixed crossbeam with a first adjustment groove, support columns at both ends, and multiple positioning sleeves for positioning shaft-like parts below. Each positioning sleeve has a positioning groove, and an arc-shaped positioning piece is placed within the groove.

The upper end of the first guide rod passes through the first guide groove on the positioning sleeve and is connected to a first stop. The two ends of the third return spring are respectively provided with a boss on the arc-shaped positioning piece and the top of the positioning groove. The positioning sleeve is connected to a first sliding block via a fixed block. The first sliding block passes through the first adjustment groove, and a second adjustment groove is positioned at the top of the first adjustment groove. A second sliding block is placed in the second adjustment groove.

[0012] Preferably, the drainage holes are rectangular in shape and are distributed linearly at equal intervals on both the fixed end plate and the sliding end plate, and both the fixed end plate and the sliding end plate are covered with a protective pad made of soft material.

[0013] Compared with the prior art, the beneficial effects of the present invention are: In this invention, multiple shaft-like parts of different lengths to be cleaned can be placed on a support plate simultaneously. One end of each shaft-like part is positioned in a limiting groove of a fixed end plate. The sliding end plate is moved along the length of the support plate until one end of the shaft-like part abuts against the inner wall of the limiting groove, and the other end is supported on a fixed pad and pressed against the sliding end plate. Rotating the adjusting screw causes the adjusting screw to push the spring stop and the limiting guide post until the limiting guide post abuts against the bottom of the guide groove. Continuing to rotate the adjusting screw stops the linear movement of the limiting guide post and causes the fixed pressure block to move towards the support plate until the pressure plate presses against the side wall of the support plate, thereby fixing the sliding end plate to the support plate. Then, the positioning sleeve is moved along with the first... The sliding block slides along the first adjustment groove on the fixed crossbeam so that the positioning sleeve is positioned directly above the shaft part to be cleaned. Rotating the first turntable causes the first screw to push the second sliding block along the second adjustment groove and press the first sliding block, thereby preventing the positioning sleeve from shifting arbitrarily. When positioning shaft parts with different radial dimensions, the arc-shaped positioning piece can move vertically along the first guide rod, and under the action of the third return spring, the arc-shaped positioning piece is pressed against the shaft part. During cleaning, the drive motor drives the active cam to move, and the active cam drives the bearing component and shaft parts to reciprocate through the driven roller, which greatly improves the cleaning efficiency, reduces labor intensity, and improves the cleaning effect.
