Braking device and equipment

Abstract

The invention discloses a braking device and equipment. The braking device comprises a first electromagnet, a second electromagnet and a current control module; the first electromagnet and the secondelectromagnet are correspondingly arranged on two braked parts which move relatively; the current control module is connected with the first electromagnet and the second electromagnet and is used forproviding first current for the first electromagnet and providing second current for the second electromagnet, so that the polarities of the opposite end parts of the first electromagnet and the second electromagnet with corresponding current input are identical; and the current control module is further used for increasing the first current and the second current along with reduction of the distance after it is determined that the distance between the two braked parts is reduced to a preset value in the process that the two braked parts get close to each other. According to the technical scheme, short-distance effective braking of the two braked parts is realized.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of braking, in particular to a braking device and equipment. Background technique [0002] At present, the cross-sectional shape of the beam is often adjusted by setting light-blocking blades on the optical path. For example, for a beam with a circular cross-section, four blades are set on a plane perpendicular to the beam propagation direction, and the four blades surround The beam is set and by adjusting the position of each blade, the blades of the four blades can form a square with a preset size. When the beam propagates to this plane, only the light in the unobstructed square area can continue to propagate, thereby realizing the beam cross section from circular to circular. to square adjustment. [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 bet...

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
