Embodiment Construction

[0032] 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.

[0033] figure 1 A structural schematic diagram of an embodiment of the vibration damping device 10 according to the present invention is shown. see figure 1 , The vibration damping device 10 includes a housing 110 and a moving part 140 .

[0034] A first sealed cavity 120 is opened in the casing 110, and the first sealed cavity 120 is used to accommodate magnetorheological fluid. One end of the casing 110 is connected with a first connecting plate 130, and the first connecting plate 130 and the casing 110 can pass through screw connection. Magnetorheological fluid is a new type of fluid that exhibits low-viscosity Newtonian fluid properties under zero magnetic field conditions, and high-vis...

Abstract

The invention provides a vibration reduction device and a machine tool. The vibration reduction device comprises: a shell, wherein a first sealing cavity is formed in the shell, the interior of the first sealing cavity is used for containing magnetorheological fluid, and one end of the shell is connected with a first connecting plate; a moving part, wherein at least part of the moving part is arranged in the first sealing cavity, the first end of the moving part penetrates out of the first connecting plate, the first end of the moving part and the first connecting plate are arranged in a sealed mode, and a wire hole is formed in the shell and surrounds the first sealing cavity, so that a magnetic field is formed in the first sealing cavity by electrifying a wire in the wire hole, wherein the moving part is movably arranged in the preset direction relative to the shell. The magnetorheological fluid can be converted into a semi-solid from a freely flowing liquid under the action of an external magnetic field, and when the moving part is stressed to move, damping force generated by the magnetorheological fluid can partially counteract impact force caused by vibration, so that the vibration reduction effect of the machine tool is improved, and the problem that in the prior art, the machining precision of the machine tool is low is solved.

Description

technical field [0001] The invention relates to the field of manufacturing, in particular to a vibration damping device and a machine tool. Background technique [0002] CNC machine tool is the industrial mother machine of equipment manufacturing industry, which has a decisive influence on the development of a country's aerospace, military and medical industries. The machining accuracy of CNC machine tools is an important indicator for evaluating its performance. Since the vibration generated by cutting is an important factor affecting the machining accuracy of CNC machine tools, at present, rubber foot pads are generally used in the manufacturing industry to reduce the vibration of CNC machine tools. , to improve the machining accuracy of CNC machine tools. [0003] However, rubber foot pads have a general damping effect on machine tools and cannot effectively improve the machining accuracy of machine tools. Contents of the invention [0004] The main purpose of the pre...
