Detailed description of the invention
Be described in further detail the utility model in conjunction with the accompanying drawings and embodiments now, these accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in figures 1 to 6, a kind of piece-holder positioner, comprise: be arranged at least two fixture blocks in same plane, and by connecting rod 2 and the drive unit be connected with each fixture block while of guide rod 3, fixture block is driven by drive unit and can convert at clip position and slack position simultaneously, the fixture block being positioned at clip position can jointly form one with the profile of workpiece 9 form fit, or be positioned at the fixture block of clip position and several alignment pins 4 can jointly form one with the profile of workpiece 9 form fit.
Connecting rod 2 is mainly used for the driving force of cylinder 1 to be transmitted to each fixture block, and the direction of motion of connecting rod 2 can be converted to the direction of motion of corresponding fixture block by the guide rod 3 that fixture block connects;
In the first embodiment, when four fixture blocks are in clip position, can simulate one with the profile of the circumferential Contour matching of workpiece 9, by the common promotion of four fixture blocks, two profiles just can accurately overlap fast.
The second embodiment is with in the third embodiment, be in three fixture blocks of clip position and alignment pin 4 jointly simulate one with the profile of the circumferential Contour matching of workpiece 9, by the common promotion of three fixture blocks, two profiles just can accurately overlap fast.
Fixture block and alignment pin 4 are disposed on the same plane, and such matching profile out just can in same plane, also comparatively easy to the clamping of workpiece 9.The profile of the profile of certain fixture block matching or fixture block and the common matching of alignment pin 4 also can time stereochemical structure, now several fixture blocks and alignment pin 4 can not in same planes.
In the first embodiment, clamping and positioning device is provided with four fixture blocks, the first fixture block 5, second fixture block 6, the 3rd fixture block 7 and the 4th fixture block 8 is followed successively by around profile, first fixture block 5 is by drive unit Direct driver, second fixture block 6 and the 4th fixture block 8 are all by connecting rod 2 and guide rod 3 connecting drive device tilted, and the 3rd fixture block 7 is by connecting rod 2 and two guide rod 3 connecting drive devices tilted.
