Abstract

A multi-motor servo direct-drive friction brake suitable for mechanical presses, including four direct-drive motors, the four direct-drive motors are connected to the upper body through a cross fixing plate, the screw of the direct-drive motor is connected to the first One friction disc is connected, the first friction disc is connected to the connecting shaft, the second friction disc is connected to the upper fuselage, the transmission shaft is connected to the upper fuselage through rolling bearings, and the brake disc is connected to the right end of the transmission shaft, more than two The friction block is evenly inlaid on the brake disc, and the friction block is in contact with the first friction disc and the second friction disc respectively during braking, and the electromagnetic servo direct drive motor is used as the power source of friction braking. When braking, the direct drive motor is controlled to work, and the direct drive motor pushes the first friction disc to move to the right through the screw, and presses the inlaid friction block to the second friction disc for braking. The present invention has the advantages of simple structure, heat dissipation Good, high energy utilization rate, flexible action, convenient operation and low cost.

Description

technical field [0001] The invention belongs to the technical field of mechanical presses, in particular to a multi-motor servo direct-drive friction brake suitable for mechanical presses. Background technique [0002] At present, there are three types of brakes commonly used on presses: disc type, belt type and brake shoe type. Disc brakes are divided into floating insert type and disc type. Band brakes are divided into eccentric band brakes and pneumatic band brakes. At present, brake shoe brakes are not used much. The traditional pneumatic brake generally uses compressed air to brake when it is in motion. This kind of brake system has a complicated structure and is inconvenient to operate. In order to increase the air pressure during braking, various valves and air compressors must be equipped, which increases the production cost. [0003] And the band brake is due to some shortcomings caused by its own structure, many of which have unsatisfactory use effects. The unev...
