Embodiment Construction

[0023] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0024] see Figure 1 to Figure 3 , the invention provides an error measuring device. The error measuring device is used for measuring the screw rod 210 , and the screw rod 210 is provided with an installation cavity 230 . The error measuring device includes an elastic member 110 and a measuring component. The elastic member 110 is arranged in the installation cavity 230 and extends along the axial direction of the screw rod 210 . The elastic member 110 is connected with the screw rod 210 to drive the elastic member 110 to deform when the screw rod 210 deforms. The measuring component is connected with the elastic member 110 to obtain the deformation of the screw rod 210 according to the defo...

Abstract

The invention provides an error measuring device and a lead screw assembly with the same. The error measuring device is used for measuring a lead screw, an installation cavity is formed in the lead screw, and the error measuring device is characterized by comprising an elastic piece and a measuring assembly, wherein the elastic piece is arranged in the installation cavity and extends in the axial direction of the lead screw, the elastic piece is connected with the lead screw, so that when the lead screw deforms, the elastic piece deforms correspondingly, and the measuring assembly is connected with the elastic piece so as to obtain the deformation amount of the lead screw according to the deformation amount of the elastic piece. Due to the fact that the deformation amount of the lead screw can be obtained only through the elastic piece and the measuring assembly, other modules do not need to be additionally arranged, cost is low, installation is convenient, and the problem that in the prior art, the mode of measuring a ball screw of a numerical control machine tool is complex is solved.

Description

technical field [0001] The invention relates to the field of numerical control machining, in particular to an error measuring device and a screw rod assembly having the same. Background technique [0002] The CNC machine tool industry is the focus of the development of the equipment manufacturing industry, and the manufacturing industry has put forward higher requirements for the accuracy of CNC machine tools. The thermal error caused by the deformation of machine tool parts caused by thermal factors in the processing process is the most important factor affecting the accuracy, accounting for 40%-70% of the comprehensive error in the entire processing process. [0003] The ball screw of the CNC machine tool is often in the condition of high-speed motion, and the friction is relatively serious. The heat generation is large and the temperature rises, which leads to a decrease in positioning accuracy. Therefore, it is necessary to measure the thermal error of the screw rod for...
