Abstract

The invention discloses a fourth shaft provided with a strong braking system for machining of a numerical control machine tool, and relates to the technical field of numerical control machine tools. The fourth shaft comprises a fourth shaft body, wherein a workpiece fixing chuck is fixedly installed on the front surface of the fourth shaft body, a fixing groove is formed in the front surface of the workpiece fixing chuck, a strong brake mechanism is arranged on the right side of the fourth shaft body, and a motor heat dissipation mechanism is arranged on the back surface of the fourth shaft body. According to the invention, a driving gear is driven to rotate by controlling a driving motor to operate, a driving rod and a driven rotating rod rotate reversely through the design of a reverse gear, a first lead screw and a second lead screw are synchronously driven to rotate reversely through the design of a chain transmission mechanism body, a sliding seat is promoted to slide, then the two abrasion plates are driven to move in the direction close to a strong abrasion brake disc, the brake shaft is decelerated through friction force between the abrasion plates and the strong abrasion brake disc, and the braking efficiency of the device is improved.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a fourth axis for machining of numerical control machine tools with a strong braking system. Background technique [0002] The fourth axis of the CNC machine tool refers to the CNC dividing head of the machining center. It can complete the tasks that the three-axis machining center cannot process at one time. It can realize multi-faceted processing of the product through rotation, which greatly improves the processing efficiency and reduces The number of clamping times, the addition of the fourth axis to the CNC machining center can make the plane of the tool processing wider, and can reduce the repeated clamping of the workpiece, improve the overall machining accuracy of the workpiece, and help simplify the process and improve production efficiency. There are following problems at prior art: [0003] 1. The existing fourth axis only brakes through the re...
