Centered on circumferentially, and be respectively facing turntable, the sliding rail of three the linear guides is fixedly connected with pedestal respectively；Three connecting rods
One end is rotatablely connected with turntable respectively, and the other ends of three connecting rods is rotatablely connected with three sliding blocks respectively, three sliding blocks respectively with
The slide of three the linear guides is fixedly connected, and is taken the lead for three and is fixedly connected respectively with three sliding blocks.
Further, the turntable is circle, and the distance in three the linear guide ends to the turntable centers of circle is equal, and three straight
Line guide rail is respectively placed on the extended line of disk diameter；Three 120 ° of the linear guide interval distributions, equally, three connecting rods and turntable
Tie point be also spaced 120 ° of distributions.
Further, the pedestal is equilateral triangle, and three the linear guides are respectively placed in three tops of equilateral triangle
At angle.
Further, one end of three connecting rods is rotatablely connected with turntable respectively by shipping and reselling on another market, and the other end of three connecting rods is logical
Of the same race ship and resell on another market is crossed to be rotatablely connected with three sliding blocks respectively.
Further, 120 ° of uniform intervals are opened there are three pin hole on the turntable, and realization is symmetrically installed.
Further, three distances taken the lead to the turntable center of circle are equal.
Further, the linear guide includes a sliding rail and a slide, and building block is easily installed debugging, and sliding
Between rail and slide can relative rectilinear sliding, realize the servo-actuated of its connecting component.
The beneficial effects of the utility model are：The utility model proposes a kind of self-centering inner circle fixture, reasonable for structure, work
Make clear principle, on the one hand solves the problems, such as that labor intensity is big, ineffective；On the other hand difficult control, quality are solved
Unstable problem；Simultaneously compact overall structure, be swift in motion, be convenient and reliable, can modularization and it is integrated, be easily installed tune
Examination.
Description of the drawings
Fig. 1 is the main structure diagram of the utility model；
Fig. 2 is the overlooking structure diagram of the utility model；
In attached drawing 1,2：Pedestal 1, the linear guide 2, motor 5, turntable 6, connecting rod 7, ship and resell on another market 8 at 3, sliding block 4 of taking the lead.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Figure 1, 2, a kind of self-centering inner circle Zhuan Cheng mechanisms, motor 5 are fixedly connected with pedestal 1, turntable 6 and motor 5
