Problems solved by technology

One of its outstanding shortcomings is that the operating range of the rotary motion is small, and the rotary range of the fully parallel six-axis parallel mechanism is only about 30° to 60°; it is designed by the German DST company and produced by the American Cincinnati company. It is called "Z3 spindle head". "The main shaft mechanism is a three-axis parallel mechanism, and its rotation range has been expanded to reach ±40°, but it still cannot realize the vertical and horizontal processing functions.

Embodiment 1

[0023] figure 2 It is a structural diagram of a 3-RPS type three-axis parallel spindle mechanism. The fixed platform 1 in the figure is connected to three rotary subassemblies 2 distributed at 120°, and the three rotary subassemblies 2 are respectively connected to three moving subassemblies 3. The three moving subassemblies 3 are respectively connected with the three rod assemblies 4, and the three rod assemblies 4 are respectively connected with the three spherical subassemblies 5, and the three spherical subassemblies 5 are connected with the moving platform 6 in 120° distribution, and the moving platform 6 is connected with the moving platform 6. The main shaft part 7 is connected. The three moving pairs are active motion pairs, which are respectively driven by servo motors, or can be driven by hydraulic pressure. The main shaft components are AC servo electric spindles, or variable frequency electric spindles.

Embodiment 2

[0025] image 3 It is the structural diagram of the 3-PRS type three-axis parallel spindle mechanism, and its implementation method is the same as figure 2 Similar, but the difference is that the linear movement pair of the parallel spindle head mechanism is in the front, and the rotary pair is behind. The A-axis and B-axis of the mechanism also exceed 90°, which can realize vertical and horizontal machining.

Abstract

A mainshaft head mechanism with parallel three shafts for performing multi-direction vertical and horizontal machining is composed of a fixed platform, threerotary sets distributed by 120 deg and connected to said fixed platform, three moving sets respectively linked to the rotay sets, three rod sets respectively linked to three moving sets, three spherical sets respectively linked to three rod sets, movable platform, and mainshaft unit installedon said movable platform. Said mainshaft unit can do longitudinal movement along Z axis and rotations around A axis and B axis.

Description

technical field [0001] The invention belongs to the field of machinery and relates to a parallel mechanism, in particular to a three-axis parallel spindle head mechanism for multi-directional vertical and horizontal machining of a parallel machine tool and a hybrid machine tool combining series and parallel. Background technique [0002] In recent years, the United States took the lead in launching a six-axis fully parallel machine tool, and other countries have successively introduced some fully parallel machine tools or hybrid machine tools that combine series and parallel. The outstanding advantages of the fully parallel machine tool are small moving mass, fast speed and high specific rigidity; no accumulation of movement errors and high precision. One of its outstanding shortcomings is that the operating range of the rotary motion is small, and the rotary range of the fully parallel six-axis parallel mechanism is only about 30° to 60°; it is designed by the German DST co...
