Embodiment Construction

[0021] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .

[0022] refer to figure 1 , The static stiffness measurement device for the vertical diameter of the lathe tool holder is suitable for the static stiffness detection of the CNC machine tools such as lathes, vertical machining centers, bedroom machining centers, and gantry machining centers. Especially for lathes with T-shaped turrets with inclined beds, the test results of the static stiffness in the vertical direction of the turrets are one of the main indicators for evaluating the static stiffness performance of the machine tool.

[0023] The vertical static stiffness measuring device of the lathe tool rest comprises a force sensor 10, an applied for...

Abstract

The invention discloses a static stiffness measuring device for the vertical diameter direction of a lathe tool holder and a measuring method thereof. The static stiffness measuring device for the vertical diameter direction of the lathe tool holder comprises a force sensor, a force applying element and a displacement measuring instrument. The force sensor has opposite upper and lower ends, and the lower end of the force sensor is fixedly disposed. The upper end of the force sensor is connected to the lower end of the force applying element, and the upper end of the force applying element is connected to the side surface of the lathe tool holder. The lathe tool holder is set fixedly. The force applying element is used for applying a load to a vertical direction of the side surface of the lathe tool holder. The force sensor is used for acquiring applied load data The displacement measuring instrument is used for measuring the vertical diameter deformation amount of the lathe tool holder. The static stiffness measuring device for the vertical diameter direction of the lathe tool holder can reduce the possibility of misjudgment of the static stiffness value of the vertical diameter direction of the lathe tool holder.

Description

technical field [0001] The invention relates to the technical field of testing basic performance parameters of machine tool functional parts, in particular to a static stiffness measuring device and a measuring method thereof in the vertical direction of a lathe tool holder. Background technique [0002] Stiffness refers to the ability of a material or structure to resist elastic deformation when a force is applied. Lathe stiffness refers to the ability of the parts on which the tool is installed and the part on which the workpiece is installed to resist deformation under the action of external force on the lathe. It is one of the main indicators for evaluating the performance of the lathe. The lathe exhibits different stiffness under different conditions. The stiffness exhibited under dynamic conditions is dynamic stiffness, referred to as dynamic stiffness; the stiffness exhibited under static conditions is static stiffness, referred to as static stiffness. [0003] With ...
