Detailed Description

A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1 and 2, the cylinder sleeve casting blank cleaning device comprises a steel wire brush 30, a first thimble mechanism 21, a second thimble mechanism 22, a first oil cylinder 23, a second oil cylinder 24, a workpiece rotating motor 20, a frame 10, a rotating shaft 31, a belt pulley 32, a belt 33, a brushing motor 34, a brushing oil cylinder 40, a connecting rod 41, a supporting seat 42 and a displacement sensor 50.

The frame 10 is a support of the whole excircle brushing and sweeping mechanism, and the brushing and sweeping motor 34, the workpiece rotating motor 20, the first oil cylinder 23 and the second oil cylinder 24 are all fixedly arranged on the frame 10.

The first and second needle mechanisms 21 and 22 are rotatable about their axes, and the first and second oil cylinders 23 and 24 each have a fixed end and a movable end that is linearly movable with respect to the fixed end. The first thimble mechanism 21 is fixedly mounted on the moving end of the first cylinder 23, and the second thimble mechanism 22 is fixedly mounted on the moving end of the second cylinder 24.

After the cylinder sleeve casting blank is fed from the previous process, the first ejector pin mechanism 21 and the second ejector pin mechanism 22 are driven by the first oil cylinder 23 and the second oil cylinder 24 to approach each other, and respectively push against two end faces of the cylinder sleeve casting blank.

The workpiece rotating motor 20 drives the first ejector pin mechanism 21 to rotate through a belt 33 or a speed reducing mechanism, and further drives the cylinder sleeve casting blank to rotate.

The two ends of the rotating shaft 31 are respectively fixedly connected with the wire brush 30 and the belt pulley 32, and the rotating shaft 31 is fixedly arranged at the lower part of the supporting seat 42 through a bearing. The brush-sweeping oil cylinder 40 drives the belt pulley 32 to rotate through the belt 33, and further drives the rotating shaft 31 and the steel wire brush 30 to rotate, the steel wire brush 30 is parallel to the axis of the cylinder sleeve casting blank, the outer circular surface of the cylinder sleeve casting blank is in mutual pressing contact, the steel wire brush 30 and the cylinder sleeve casting blank rotate in opposite directions, and the defects of sand sticking and the like on the outer circular surface of the cylinder sleeve casting blank are abraded through the steel wire brush 30.

The supporting seat 42 is hinged with the frame 10 and can rotate up and down relative to the frame 10, the connecting rod 41 is fixedly connected with the supporting seat 42, the brushing and sweeping oil cylinder 40 is provided with a fixed end and a moving end which can do linear motion relative to the fixed end, and the moving end of the brushing and sweeping oil cylinder 40 is hinged with the connecting rod 41; when the moving end of the brushing oil cylinder 40 extends out, the supporting seat 42 rotates downwards, the steel wire brush 30 moves downwards, and when the moving end of the brushing oil cylinder 40 retracts, the supporting seat 42 rotates upwards, and the steel wire brush 30 moves upwards; the outer diameters of different cylinder sleeve casting blanks are different, the position of the steel wire brush 30 can be changed by adjusting the stroke of the moving end of the brush sweeping oil cylinder 40, and switching of different specifications is completed.

The displacement sensor 50 is used for detecting the stroke of the brush-sweeping cylinder 40, and can judge whether the wire brush 30 reaches the set position.
