Problems solved by technology

This type of table has one degree of freedom of rotation and one degree of freedom of tilting, and has limited capabilities in processing complex curved surface parts
[0004] In addition, there are currently some two-degree-of-freedom tilting tables with two mutually perpendicular rotation axes. The basic principle is the superposition of two traditional single-degree-of-freedom tilting tables. On the other hand, the overall rigidity of the workbench is relatively insufficient

Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The present invention is a high-rigidity double-ball pair two-degree-of-freedom tiltable workbench, which consists of four parts: a workpiece fixing table 1, an upper table 2, a double-ball middle table 3, and a lower table 4.

[0027] See figure 1 , figure 2 , the workpiece fixing table 1 is a fixing plate with a T-shaped groove, which is used to cooperate with T-shaped bolts to fix the workpiece. The workpiece fixing table 1 and the upper ball sub-housing 201 of the upper table 2 are fixedly connected by screws.

[0028] See Figure 1 ~ Figure 3 The left and right rotation shafts 217 and the right rotation shaft 203 respectively equipped with bearings 205 are installed in the left and right holes of the upper ball sub-housing 201 of the upper stage 2 part, and the left rotation shaft 217 and the right rotation shaft 203 pass through the pressure ...

Abstract

The invention discloses a double-ball-pair two-freedom-degree inclinable working table. The double-ball-pair mode is adopted for the working table, a part of a spherical face is directly used as a guide rail face, the structure is compact, and the system rigidity is high. Two rotation freedom degrees in two perpendicular directions are achieved. The double-ball-pair two-freedom-degree inclinable working table can be used in cooperation with an annular cutter, a taper milling cutter and the like for the five-axis numerical control machining of most complex curved surface parts. The rotation angles in the two perpendicular directions can be output through a rotation encoder. Through the combination with the power outage braking of an electromagnetic brake and the self-locking function of a worm and a worm wheel, a workpiece fixing tabletop of the working table can be accurately and reliably fixed at the required inclination angle.

Description

technical field [0001] The invention relates to a tiltable workbench, in particular to a tiltable workbench which is driven by a motor and utilizes double ball pairs to realize two rotational degrees of freedom perpendicular to each other, so that the workpiece fixing surface of the workbench can be adjusted according to the designed parameters. The required angle and direction inclination can cooperate with the machine tool spindle to realize the processing of complex structural parts. Background technique [0002] The processing of complex parts, especially complex surface parts (such as turbine blades), requires complex relative motion between the tool and the workpiece, which means that the tool has more degrees of freedom relative to the workpiece. Generally, the complexity of part processing depends on the degree of freedom of the spindle of the machine tool. The more degrees of freedom of the spindle, the stronger the processing capability of complex parts, and at the...
