Simple testing device for return difference of electric cylinder and testing method thereof

Abstract

The invention discloses a simple electric cylinder return difference testing device and a testing method thereof. The simple electric cylinder return difference testing device comprises a supporting part, a fixing part, a testing part and a loading part, the fixing part and the testing part are arranged on the supporting part, the fixing part is used for fixing an electric cylinder to be tested, a sliding piece and a testing piece are arranged in the testing part, the testing piece is connected with the output end of the electric cylinder to be tested, and the sliding piece is connected with the testing piece and the loading part. The supporting part is provided with a first mounting hole site and a second mounting hole site which are matched with the loading part, and the loading part can be switched between the first mounting hole site and the second mounting hole site to enable the sliding piece to be far away from or close to the electric cylinder to be tested; according to the scheme, through the optimized design, the mechanical gaps among the matching parts are controlled at an extremely low level, and the measurement result is basically not influenced, so that the measurement requirement of the high-precision electric cylinder return difference is met.
