Abstract

This invention discloses a self-aligning and positioning rotating device for use after a rotating body has moved, comprising: a rotating component, a steel ball, and an upper coupling. The upper end of the upper coupling is connected to a drive shaft, and the lower end is movably connected to the rotating component. The lower end of the upper coupling has an L-shaped boss, with inclined surfaces on both inner sides of the L-shaped boss, and the two inner sides of the L-shaped boss are equidistant from the center of the upper end of the upper coupling. An L-shaped groove is provided at the connection between the rotating component and the upper coupling, with the two inner sides of the L-shaped groove equidistant from the center of the rotating component. When the upper coupling is inserted into the rotating component, the L-shaped boss is embedded in the L-shaped groove, and the inclined surface of the boss is tangent to the steel ball. When the inclined surface of the upper coupling contacts the steel ball placed in the rotating component, it adjusts the displacement error generated when the rotating component moves to a designated position, thereby enabling the rotating component to achieve concentricity with the drive shaft. This prevents excessive load on the drive end due to misalignment during rotation, which would lead to excessive wear and reduced service life.

[0030] The rotating member 1 can be a cylinder, or can be a transition connecting member of a large cylinder. The connecting position of the rotating member 1 and the upper connecting shaft 3 is provided with an L-shaped groove 11 corresponding to the position of the L-shaped boss 31, the size of the L-shaped groove 11 is greater than the size of the L-shaped boss 31, so as to ensure that the L-shaped boss 31 can be embedded into the L-shaped groove 11.

The center of the rotating member 1 is located within the included angle formed by the two edges of the L-shaped groove 11, and the two inner edges of the L-shaped groove 11 are kept the same distance from the center of the rotating member 1.

The included angle of the L-shaped groove 11 of the rotating member is provided with a clearance 111 for accommodating the steel ball 2, and the bottom surface of the L-shaped groove 11 is provided with a limiting portion 112 corresponding to the steel ball 2, the steel ball 2 is located in the limiting portion 112, and the limiting portion 112 limits the steel ball 2 to avoid rolling out of range.

[0032] When the upper coupling 3 is inserted into the rotating member 1, the L-shaped boss 31 is embedded into the L-shaped groove 11, and the inclined surface 32 of the L-shaped boss 31 is tangent to the steel ball 2.

[0033] In use, the upper end of the upper coupling 3 is fixedly installed on the driving shaft 4, and the steel ball 2 is located in the rotating member 1. When the rotating member 1 is located at a specified position below the upper coupling 3, the L-shaped boss 31 of the upper coupling 3 is inserted into the L-shaped groove 11 of the rotating member 1 from top to bottom. When the inclined surface 32 of the L-shaped boss of the upper coupling 3 is in contact with the steel ball 2 placed in the rotating member 1, the displacement error generated when the rotating member 1 moves to the specified position is adjusted, so that the rotating member 1 can achieve the effect of concentricity with the driving shaft 4, and the excessive wear of the driving end caused by the eccentricity of the rotating member 1 during movement is reduced, thereby increasing the service life of the driving end parts.

[0034] The top surface of the upper coupling 3 is provided with a recess 33 for positioning the driving shaft 4.

[0035] The cylindrical end of the upper coupling 3 is provided with a plurality of through holes 34, which are connected with the driving shaft 4 through the through holes 34.

[0036] The application also provides a rotating movement mechanism, which comprises the aligning and positioning coupling rotating device as described above, and further comprises a driving shaft mechanism, a lifting mechanism and a translation mechanism (not shown), wherein the driving shaft mechanism comprises the driving shaft 4.

[0037] The aligning and positioning coupling rotating device comprises a plurality of rotating members 1, a plurality of steel balls 2 and an upper coupling 3. The rotating members 1 and the steel balls 2 are of the same size, and the size of the upper coupling 3 matches the sizes of all the rotating members 1 and all the steel balls 2.

[0038] The upper end of the upper coupling 3 is fixedly connected with the driving shaft 4, and the driving shaft 4 is used to drive the upper coupling 3 to rotate.

[0042] The rotating movement mechanism further comprises a positioning mechanism, which is used to position the position of the rotating member 1.

[0043] The working process of the rotating movement mechanism is as follows:

[0044] Suppose there are three stations, in turn, respectively, station A, B, C station, A, B station is provided with a corresponding one of the rotating body 1, respectively, rotating body A, rotating body B, each rotating body 1 is provided with a steel ball 2, the drive shaft 4 is located in the B station.

[0045] When the drive shaft 4 is stopped at a fixed position by using the encoder, the rotating member B connected with the drive shaft 4 also stops rotating, and then the lifting mechanism lifts the drive shaft 4 to bring the upper coupling 3 to a position higher than the rotating member B, at which time the upper coupling 3 is separated from the rotating member B.

[0046] The translation mechanism drives the rotating member B to move to the C station, and at the same time, the translation mechanism drives the rotating member A to move to the B station, so that the workpiece carried on the rotating member is shifted. The translation mechanism and the positioning mechanism jointly act to position the rotating member A directly below the drive shaft of the B station. The lifting mechanism lowers the drive shaft 4 and the upper coupling 3, and slowly moves them downward. The L-shaped boss of the upper coupling 3 is used to adjust the position of the rotating member A by using the slope 32 of the L-shaped boss and the steel ball 2, so that the rotating member A is adjusted to be concentric with the positioning of the drive shaft 4. Then the drive shaft 4 drives the rotating member A to move. The operation is sequentially cycled.

[0047] The above is only a preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
