Embodiment 1

[0085] This embodiment provides a modular shock absorber, such as figure 1 As shown, it includes at least one vibration absorber unit and at least one set of connecting components a2 connecting the vibration absorber unit. The vibration absorber unit includes a vibration absorber unit a0 and a connection structure a1. The connection structure a1 is polyhedral, and it is sheathed outside the vibration absorber unit a0. Any inner wall surface of the connection structure a1 is at least partially in contact with the outer surface of the vibration absorber unit a0, so as to fully reduce the distance between the vibration absorber unit a0 and the connection structure a1. The space between the connection structure a1 and the vibration absorber unit a0 is more compact, and any surface on the polyhedron avoiding the plug a01 can be used as the connection surface, so that any two vibration absorber units a0 can pass through their respective The connection surfaces on the connection stru...

Embodiment 2

[0105] This embodiment provides a modular shock absorber. Compared with the technical solution of Embodiment 1, the difference is that, as Figure 4 As shown, the limit part of the vibration guide assembly of the vibration absorber unit a0 adopts a flange 73, and the flange 73 is coaxially threaded on the central axis 82 and fixed on the mover core 3 at both ends of the mover. 73 is located in the inner ring of the secondary permanent magnets 6 at both ends, and the elastic member adopts a leaf spring 74, which is symmetrically distributed about the flange 73. In the present embodiment, the leaf spring 74 is circular, and the edge of the circular inner ring is fixed on On the outer peripheral surface of the flange 73, the outer edge of the flange is fixed on the inner step of the seal between the cover plate 2 and the casing 1. When the mover is in a balanced state, the surface of the leaf spring 74 is arranged perpendicular to the axial direction of the mover.

Embodiment 3

[0109] This embodiment provides a vibration absorber module, including the external connector a3 and the modular vibration absorber in Embodiment 1 or Embodiment 2. Such as Figure 8 As shown, one of the connection structures a1 is provided with an external connector a3, and two modular shock absorbers are coaxially stacked and fixedly connected together with respect to the shock absorber unit a0 to form a shock absorber with twice the output force. Similarly, Three, four, etc. can be stacked coaxially to form a triple, quadruple output force absorber.

Abstract

The invention provides a modularized vibration absorber, a vibration absorber module and a machine tool. The modularized vibration absorber comprises at least one vibration absorber unit and at leastone connecting assembly. Each vibration absorber unit comprises a vibration absorber single body and a connecting structure, wherein the connecting structure is in a polyhedral shape and arranged outside the vibration absorber single body in a sleeving mode; and any inner wall surface of the connecting structure is in local contact with the outer surface of the vibration absorber single body, thegap between the vibration absorber single body and the connecting structure is fully reduced, and thus the space between the connecting structure and the vibration absorber single body is more compact. Any surface, far away from a plug, on the polyhedral bodies can serve as connecting surfaces, thus any two vibration absorber single bodies can be fixedly connected together through the connecting surfaces of the corresponding connecting structures, multi-degree-of-freedom combination of the vibration absorbers is achieved, when the multiple vibration absorber single bodies which are overlaid through the connecting surfaces are arranged coaxially, the output force can be multiplied axially, the structure is compact, the vibration absorber single bodies only need to be overlaid in the same direction so that the output force can be adjusted, and conveniences and the rapid effect are achieved.

Description

technical field [0001] The invention belongs to the technical field of vibration absorption, and in particular relates to a modular vibration absorber, a vibration absorber module and a machine tool. Background technique [0002] In many industrial fields, mechanical vibration is an engineering problem that cannot be ignored. Vibration absorbers are widely used as a common means of vibration control, and active vibration absorption, as the ultimate form of vibration absorbers, can suppress vibration to the greatest extent. [0003] The traditional active electromagnetic vibration absorber has a single installation form and its application is limited. Chinese patent document CN102168738A discloses a six-degree-of-freedom active and passive dynamic vibration absorbing device, which proposes a scheme in which six single-degree-of-freedom dynamic vibration absorbers are fixed to three vertical directions of the support with screws in a pair-by-two symmetrical layout. The suppo...
