Embodiment Construction

[0016] The opening and closing of the driven wheel left brake 7 and the driven wheel right brake 8 controls the rotation of the driven wheel 12. When the driven wheel left brake 7 and the driven wheel right brake 8 are closed, the driven wheel 12 stops quickly due to tangential resistance sports. The driven wheel 12 can be accurately positioned at a certain angular position by the applied force and the opening and closing time of the left brake 7 of the driven wheel and the right brake 8 of the driven wheel. At this time, the manipulator positioning hole 10 for grabbing the product on the driven wheel 12 is on the corresponding station, so that the product is just aligned with the operating device 13 for processing. After the driven wheel 12 is completely stationary, the operating device 13 performs corresponding operations on the stationary product. At this moment, the driving wheel 6 rotates under the drive of the motor 2 and the restoring force of the spring. Since the dri...

Abstract

The invention relates to a resonant multi-position turntable of high speed and high precision applied for the industrial automation, in particular to a multi-position turntable in situations with strict requirements upon speed and precision, comprising a base (1), a motor (2), a metal shaft (3), a spring (4), a mounting hole (5), a main driving wheel (6), a left brake of a driven wheel (7), a right brake of the driven wheel (8), a first raster ruler (9), a locating hole for a manipulator(10), a bearing (11), a fixed connection of the driven wheel (12), an operating apparatus (13), a controller (14), a support (15), a metal shaft (16), a left brake of the main driving wheel (17), a right brake of the main driving wheel (18), and a second raster ruler (19). The invention has the advantages of high precision, high speed, less energy consumption, avoidance of motors of high power and high precision as drives, utilization of common elements and technologies, and great reduction in cost compared with the traditional technical proposal.

Description

technical field [0001] The invention is a multi-station turntable used in industrial automation, especially in occasions with high requirements on speed and precision. Background technique [0002] Multi-station turntable is a device widely used in industrial automation. The principle is that through the rotation of the turntable, the products are sent to each station in turn for processing, thereby realizing automatic production. [0003] In the production of many precision products, multi-station turntables are often required to have extremely high station switching speed (station switching times ≥ 10 times / s), and very precise positioning accuracy (station positioning error ≤ 10um). The manufacture of this high-speed, high-precision multi-station turntable is very difficult. The traditional method is to use a high-power, high-precision stepping motor or servo motor to drive the turntable to rotate. This high-performance motor is currently mainly imported and expensive....
