Problems solved by technology

[0002] Usually, the outer dimensions of the long stator core of a linear motor are measured manually. The long stator is placed on the working plate, and the flatness and height of the long stator are measured with a feeler gauge. This method is slow, inefficient, and poor in accuracy.
If the external dimensions of the long stator are measured with a three-dimensional coordinate measuring machine, although the accuracy is high, it is time-consuming and the price of the three-dimensional coordinate measuring machine is expensive

Abstract

The invention discloses a testing device of the outside dimension of a long stator iron core, and the testing device has the characteristics of convenient operation and fast measurement speed. The testing device comprises a desk machine frame. The desk face of the machine frame is provided with a measurement position and a hanger and is longitudinally provided with a pair of guide rails from the measurement position to one end side of the desk face. The testing device also comprises a positioning car which can be movably installed on the guide rails, a pair of parallel linear bearings which pass through the machine frame desk face vertically, upper and lower measurement substrates which are above and under the desk face of the machine frame respectively in a parallel way and are fixed on the bearing sleeves and bearing cores of the linear bearings respectively, two displacement sensors which are respectively installed at the surfaces of the upper and lower measurement substrates, a positioning component which is installed at the lower surface of the upper measurement substrate, and long stator iron cores which are installed on the hanger of the machine frame and under the desk face respectively. The top ends of the piston rods of the long stator iron cores are respectively connected with the upper and lower cylinders of the upper and lower measurement substrates, and the long stator iron cores are installed on the positioning car. The surfaces of the upper and lower measurement substrates facing measurement position of the machine frame are respectively equipped with a measuring head.

Description

technical field [0001] The invention relates to a test device, in particular to a test device for the external dimensions of a long stator core by means of physical properties. Background technique [0002] Usually, the outer dimensions of the long stator core of a linear motor are measured manually. The long stator is placed on the working plate, and the flatness and height of the long stator are measured with a feeler gauge. This method is slow, inefficient, and poor in accuracy. If the external dimensions of the long stator are measured with a three-dimensional coordinate measuring machine, although the accuracy is high, it is time-consuming and the price of the three-dimensional coordinate measuring machine is expensive. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide a test device for the external dimensions of the long stator core, which has a scientific and reasonable structure and h...
