Embodiment Construction
[0010] The present invention will be further described below in conjunction with the accompanying drawings.
[0011] Such as figure 1 As shown, a platform rotary positioner control device includes a motor 1 and a reducer 2 connected to each other installed on the positioner base 7, and a cam disc 4 is connected to the reducer, and the cam disc 4 One side is provided with a sheave 5 connected with the tooling of the positioner, and the cam plate 4 is provided with a cylinder 6 that can be snapped into the groove of the sheave 5 . In this embodiment, the transmission ratio of the reducer is 205, and the sheave 5 is a 90° sheave.
[0012] When the output shaft of the reducer rotates one circle, the sheave 5 is driven to rotate 90°, wherein, when the output shaft of the reducer rotates for a quarter of a turn, the sheave is driven to rotate 90°, and the output shaft of the reducer rotates 90°. In the last three-quarters of a turn, the sheave remains stationary, that is to say, w...

The invention discloses a control device of a rotary displacement machine of a platform. The control device comprises a motor and a speed reducer installed on a base of a displacement machine, among which a cam plate is connected to the speed reducer, and a groove wheel connected with the positioner is arranged on one side of the cam plate, and a cylinder can be inserted into the groove of the groove wheel. In that invention, the rotation angle of the shift machine is controlled by the conventional motor plus the speed reducer, and when the front fourth turn of the output shaft of the speed reducer is rotating, the driving sheave is rotated by 90 deg., and when the output shaft of the speed reducer is rotated by three-fourths of the turn, the grooved wheel is kept stationary, that is, the rotation angle of the sheave can be controlled by controlling the motor contracting brake in three-fourths of the rotation of the speed reducer, and the precision control of the rotation angle of the displacement machine is realized by the mechanical structure matching with the ordinary motor, and the cost is reduced.
Description
technical field [0001] The invention relates to a control device for a platform rotary positioner, belonging to the technical field of positioner control. Background technique [0002] During the rotation of the positioner, precise and fast control of its rotation angle is required. The existing control method is usually controlled by a high-precision servo motor, but this control method is not only costly, but also in the long-term use. Accuracy cannot be guaranteed. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a control device for a platform rotary positioner, which can precisely control the rotation angle of the positioner through a mechanical structure and an ordinary motor. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] A control device for a platform rotary positioner, comprising a connected motor and a r...
