High-precision station switching device

Abstract

The invention relates to the field of industrial automation, in particular to a high-precision station switching device simple in structure and low in manufacturing cost. The high-precision station switching device comprises a working table, a station rotating plate, a servo motor and a constant-torque motor. A reduction box, the servo motor and the constant-torque motor are disposed on the working table. The reduction box comprises a body, an output end, a first input end and a second input end. The station rotating plate is connected with the output end of the reduction box. The servo motor is connected with the first input end of the reduction box. The servo motor provides drive torque for the first input end. The constant-torque motor is connected with the second input end of the reduction box and provides resistance torque for the reduction box. The drive torque output by the servo is more than two times of the resistance torque output by the constant-torque motor.

Description

technical field [0001] The invention relates to the field of industrial automation, in particular to a high-precision station conversion device with simple structure and low manufacturing cost. Background technique [0002] In automatic assembly or loading and unloading, in order to achieve multi-station cycle operations, it is often necessary to set up a cam divider to transport materials or workpieces to corresponding stations for processing. However, in addition to the complicated structure and control method and inconvenient installation, the existing cam splitters also have the following disadvantages: 1. The number of stations is fixed and cannot be adjusted; 2. The number of stations is limited by design and manufacturing, and there are many stations. The manufacturing cost of the cam divider is very high; 3. When a station using the cam divider cannot complete the corresponding task on time for some reason (such as external feeding delay), the system can only brake u...

Problems solved by technology

However, in addition to the complicated structure and control method and inconvenient installation, the existing cam splitters also have the following disadvantages: 1. The number of stations is fixed and cannot be adjusted; 2. The number of stations is limited by design and manufacturing, and there are many stations. The manufacturing cost of the cam divider is very high; 3. When a station using the cam divider cannot complete the corresponding task on time for some reason (such as external feeding delay), the system can only brake urgently, so that many The phenomenon of failure has become a failure shutdown; 4. Even a high-precision cam splitter will cause a decrease in accuracy due to mechanical wear

[0003] At the same time, there is also a torque motor rotary platform, which can also provide high-precision station conversion, and does not have the above-mentioned shortcomings of the cam divider, but its market price is too high, and it is currently not accepted by general designs and users.
