Brakes for automated machinery

Abstract

The invention discloses a braking device for an automatic machine. The problems that an armature block manner is adopted in existing motor brakes, an armature block is prone to being damaged and getting failures, and the brake braking cost is high are effectively solved. The braking device comprises a main shaft. An inner tooth ring is arranged at the left end of the main shaft, the left side of the inner tooth ring is fixedly connected with an output shaft, and a fixed outer tooth ring is arranged on the outer side of the inner tooth ring. The inner tooth ring and the outer tooth ring are coaxial. A first groove and a second groove are formed in the outer edge of the inner tooth ring. A first pin roller is slidingly arranged in the first groove, and the first pin roller is connected witha first spring. A second pin roller is slidingly arranged in the second groove, and the second pin roller is connected with a second spring. The right end of the first pin roller is connected with a horizontal first connecting rod, the right end of the first connecting rod is connected with a vertical casing pipe, and a first sleeve is arranged on the lower side of the first casing pipe. The mainshaft is further provided with a first rotary disc, the first sleeve is fixed to the first rotary disc, and the main shaft is provided with a first torsional spring tightly wound around the main shaft. One end of the first torsional spring is connected with the main shaft, and the other end of the first torsional spring is connected with the first rotary disc.

Description

technical field [0001] The invention relates to the technical field of brakes, in particular to a brake device for automatic machinery. Background technique [0002] At present, the motor brake is to install an electromagnetic brake at the tail of the motor. When the motor is powered on, the electromagnet attracts the armature block, and the armature block and the brake are in a separated state. This means that the armature block does not brake the motor. When the motor is powered off, the armature block The block is in a tight state with the brake under the action of the spring, and the armature block brakes the motor. This motor braking method is particularly prone to failure and damage, and the armature block needs to be replaced frequently, resulting in an increase in equipment maintenance costs; another motor brake What is used is to add a brake on the motor shaft, and the brake is used to control the braking of the motor. The way of using the brake requires an addition...
