Embodiment
The utility model will be further described with reference to the embodiment in accompanying drawing below：
As shown in Fig. 1 ~ 3, the utility model mainly includes mounting base 1 and sleeve assembly.Mounting base 1 is provided with multiple
Fixed bolt hole 4, each fixed bolt hole 4 is interior to be provided with a fixing bolt, and mounting base 1 is fixed on into machine by fixing bolt
On body.
The first keeper 2 and the second keeper 3, the first keeper 2 and the second keeper 3 are connected on the mounting base 1
It can realize and to be accurately positioned with FE Tiler.First keeper 2 is chamfered edge pin, and the second keeper 3 is straight pin.
Mounting base 1 is provided with multiple centre bores 5, and an arc groove 6, the place of arc groove 6 are provided with around each centre bore 5
The round heart and the center of circle of centre bore 5 are concentric.The one end of arc groove 6 is provided with instruction counterbore 7, and the depth of instruction counterbore 7 is more than arc groove 6
Depth.The stroke that the stroke of arc groove 6 tightens bolt needed for is set, so as to reach the purpose that control bolt tightens degree.
As shown in Fig. 4 ~ 5, sleeve assembly includes rocking arm 8, sleeve 9, clamping screw 10, instruction pin 11, spring 12 and opening
Pin 13.
The center of rocking arm 8 is provided with sleeve mounting hole, is provided with sleeve 9 in sleeve mounting hole, the lower end of sleeve 9 is stretched into centre bore 5
