Electrical brake for panoramic puzzle system and television panoramic puzzle system

Abstract

The invention relates to an electrical brake for a panoramic puzzle system and a television panoramic puzzle system. The electrical brake comprises a supporting frame, a fixing piece, a nut, a motor mounted at the lower end of the supporting frame, a guide sleeve arranged in the supporting frame and a screw rod mounted at the upper end of the supporting frame through the nut, wherein a pin shaft inserted into a member to be braked is arranged at the top of the screw rod; the guide sleeve is provided with a shaft hole passing through two ends and a long hole passing through the side wall; a motor shaft of the motor is inserted and fastened in the shaft hole; the screw rod extends into the shaft hole; the screw rod is provided with a penetrating hole; and the long hole and the penetrating hole are used for enabling the fixing piece to pass. When the electrical brake works, the motor rotates to enable the pin shaft of the screw rod to be inserted into the member to be braked to achieve abraking effect on the member to be braked. The television panoramic puzzle system comprises a moment motor, a rotary table, a television camera and an electrical brake for limiting rotation of a turntable of the rotary table. The electrical brake disclosed by the invention is good in braking effect, small in size and convenient to install, can realize automatic control and is easy to operate.

Description

technical field [0001] The invention belongs to the field of mechanical transmission, and in particular relates to an electric brake for a panorama mosaic system and a TV panorama mosaic system. Background technique [0002] The hardware composition of the TV panorama mosaic system is mainly a one-dimensional turntable driven by a torque motor, on which a TV camera can be installed to monitor the target environment at 360°. Using the torque motor direct drive method to reduce the transmission link can make the turntable have higher positioning accuracy and regression accuracy, which is convenient for the camera to make a panoramic mosaic of images. However, due to height restrictions, a torque motor with a power-off and shaft-holding cannot be used. Therefore, when the turntable is powered off, the azimuth turntable of the turntable is in a state of free rotation, and the free rotation of the turntable will reduce the positioning accuracy and return accuracy of the turntabl...
