Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing:

[0016] Depend on Figure 4 combine image 3 , 5 , shown in 6 and 7, a kind of accessory type double pendulum angle milling head driven by AC permanent magnet synchronous inner rotor torque motor, comprises fork frame 22, main shaft 24, rotary joint assembly 20, described fork frame 22 and The main shaft 24 is all one-piece, and its structure will be described in detail below. This one-piece structure is different from the previous split structure, which makes the main shaft more rigid and makes the overall structure more compact. The top of the fork frame 22 has a motor base 10, the top of the motor base 10 is fixed with a connecting plate 8, the upper part of the connecting plate 8 is fixed with a pull stud 7, and the side is provided with a positioning key 19. By increasing the connecting plate 8, the The pull stud 7 and the positioning key 19 can be used to be connect...

Abstract

The invention discloses an accessory type double pendulum angle milling head driven by an alternating-current permanent-magnet synchronous inner rotor torque motor, and mainly solves the problems of low integral rigidity and complicated structure of the conventional double pendulum angle milling head. The accessory type double pendulum angle milling head is characterized in that: a forked frame (22) and a main shaft (24) respectively have an integral structure; the upper part of the forked frame (22) is provided with a motor seat (10); the top of the motor seat (10) is fixed with a connecting plate (8); and the upper part of the connecting plate (8) is fixed with a blind rivet (7) used for connecting a host, and the side face is provided with a positioning key (19). The double pendulum angle milling head has the characteristics of simple structure and high rigidity, and can be used as a host accessory.

Description

technical field [0001] The invention relates to the mechanical field, in particular to an accessory type double-swing angle milling head driven by an AC permanent magnet synchronous inner rotor torque motor. Background technique [0002] The double-swing angle milling head is the key component of the five-axis linkage CNC machine tool. In order to realize the high-speed drive of the double-swing angle milling head, the advanced torque motor direct drive technology is generally used, which can save the intermediate links such as gears, and can obtain high Dynamic performance and good positioning accuracy. At present, the double-swing angle milling head driven by the torque motor, the A-axis mostly adopts a split fork frame or a split spindle. figure 1 A schematic diagram of the A-axis structure of the double-swing-angle milling head with a split yoke frame is given, wherein the yoke frame is composed of a left ear piece 1, a connecting piece 2, and a right ear piece 3, and...
