A braking device and equipment

Abstract

The invention discloses a brake device and equipment. The braking device includes: a first electromagnet, a second electromagnet, and a current control module; wherein, the first electromagnet and the second electromagnet are respectively installed on two relatively moving braked parts; The current control module is connected with the first electromagnet and the second electromagnet, and is used to provide a first current for the first electromagnet and a second current for the second electromagnet, so that The opposite ends of the first electromagnet and the second electromagnet that input the corresponding current have the same polarity; After the distance between the braked components decreases to a preset value, the first current and the second current increase as the distance decreases. The technical solution provided by the embodiment of the present invention realizes effective braking of two braked components at a short distance.

Description

Technical field [0001] Embodiments of the present invention relate to the field of braking techniques, and more particularly to a brake device and a device. Background technique [0002] At present, the cross-sectional shape of the beam is often adjusted, and the beam of the beam is adjusted, and the cross section is a rounded beam, four blades are disposed on the plane perpendicular to the direction of the beam propagation direction, and four blades are surrounded. The beam is arranged and the cutting edge of the four blades can cause the four blade of the blade to constitute a square of the preset size, and when the light beam propagates to the plane, only the light in the unbamable square area can continue to propagate, and then achieve the beam section from circular To the square adjustment. [0003] During the actual application, the size of the beam is small, so that the distance between the relative to the blade is smaller, in the process of adjusting the two relative blad...

AI Technical Summary

Problems solved by technology

[0003] In the actual application process, the size of the light beam is small, so that the distance between the relative blades is small. In the process of adjusting the distance between the two relative blades, if the control system fails, the two blades that are closer to each other are easy to contact and collide, causing blade damage

The blade is usually installed on the knife rest. In order to solve the above problems, the knife rest can be braked by setting a braking device on two relative knife rests, but the braking force of the braking device in the prior art is usually fixed. Unchanged, the buffer distance is large, and the impact between the two tool holders cannot be effectively suppressed
