Embodiment Construction

[0020] The present invention will be further described below in combination with the embodiments and with reference to the accompanying drawings.

[0021] A high-precision locking mechanism resistant to large shocks and vibrations, including a locking seat, a worm gear, a toothed plate, a bearing, a guide rod, and a dense ball shaft system. The locking seat (1) is the base of the locking mechanism, and the rest of the parts are installed on the locking seat (1), and the locking seat (1) can be fixed on the calibration device by screws. The worm wheel (2) is installed in the central circular hole of the locking seat, and the axial direction of the worm wheel (2) is supported by two angular contact ball bearings (4). A worm (3) is installed in the transverse hole of the locking seat (1) to cooperate with the worm wheel (2), and the axial direction of the worm (3) is also supported by two angular contact ball bearings (4). A locking motor seat (5) is installed at the output end ...

Abstract

The invention relates to a locking mechanism capable of resisting large impact and vibration. The locking mechanism is driven by a servo motor, through a worm and gear and threads are transferred to drive a fixed fluted disc to perform a linear movement until the fixed fluted disc and a movable fluted disc (are installed on the carrier) are completely meshed, so that the positioning and locking functions can be realized. The worm and gear is designed to be a worm and gear capable of self-locking, so that the locking mechanism can be reliably locked, the phenomenon that looseness occurs is avoided, a threaded connection mode is adopted for the worm gear and the fluted disc, and can be prevented from being loosened under a certain friction force; meanwhile, the high-precision positioning ofthe fixed fluted disc can be realized under the cooperation of guide dense beads; and the high-precision locking mechanism can achieve high-impact resistance and vibration resistance.

Description

technical field [0001] The present invention relates to some kind of high-precision positioning and locking equipment, especially relates to the high-precision locking equipment under complex environment (high and low temperature, impact, vibration, etc.), mainly used in some special turntable equipment, when the turntable is stationary, it needs Perform locking with a certain degree of precision, and this precision can also be guaranteed in complex environments. Background technique: [0002] With the development of new technology and the needs of industry, the calibration technology is also constantly developing. In order to meet more advanced calibration methods, the calibration equipment can be automatically locked after the calibration is completed, and the accuracy of locking can be guaranteed to remain unchanged under the requirements of large shock and vibration. However, the traditional locking mechanism is relatively large, and its ability to resist shock and vibr...
