Detailed Description

Example one

Please refer to fig. 1 to 3, which are schematic structural views of a positioning fixture clamping mechanism according to the present invention. The positioning jig clamping mechanism comprises a supporting platform 10 and a positioning jig 20 which is arranged at the upper end of the supporting platform 10 in a limiting manner; a locking structure 40 arranged at the lower end of the support platform 10; and the lifting driving mechanism 30 is used for driving all the locking structures 40 to lift. It is understood that the positioning jig clamping mechanism further includes other functional components and specific structures, such as electrical connection components, mounting structures, etc., which are well known to those skilled in the art, and therefore, the details thereof will not be described herein.

Supporting platform 10 is the upper end plane of support frame promptly for install spacing positioning jig 20, supporting platform 10 upper end is equipped with two at least butt and is in the support column 11 of positioning jig 20 lower extreme, this support column 11 is used for the bottom height of lifting positioning jig 20, reduces positioning jig 20 bottom and supporting platform 10's area of contact, prevents that positioning jig 20 and supporting platform 10 from producing the installation and interfering, does benefit to positioning jig 20's location planarization, and positioning jig 20 bottom has the breach simultaneously, more does benefit to the realization automatic centre gripping. Support platform 10 upper end is equipped with two at least circumferences and sets up the spacing post 12 in the outside of positioning jig 20 circumference, and spacing post 12 butt is in the outer wall of positioning jig 20 forms the horizontally removal restriction, and it can be thought that spacing post 12 is cylindrically, and the outer wall of positioning jig 20 is equipped with the arc breach that supplies to correspond spacing post 12 card and go into, and this locate mode is more accurate reliable.

The lifting driving mechanism 30 drives the locking structure 40 to vertically move, and comprises a driving plate 31 arranged below the supporting platform 10, at least three guide columns 32 arranged at the lower end of the supporting platform 10 and penetrating through the driving plate 31, and a driving cylinder 33 driving the driving plate 31 to move. The driving cylinder 33 can drive the driving plate 31 to move relatively to the supporting platform 10 along the guide column 32 below the supporting platform 10. The whole driving process is located below the supporting platform 10, so that the occupied space above the supporting platform 10 is reduced, and the movement interference with the CNC process is avoided. The lower end of the driving plate 31 is provided with a butting column 13 for limiting the descending height of the driving plate 31, so that the lowest descending height of the locking structure 40 is prevented from being set by the driving plate 31 from excessively descending.

Hasp structure 40 for it is spacing that positioning jig 20's upper end, hasp structure 40 includes that two at least intervals set up positioning jig 20's hole 41 of stepping down, at least two settings are in last revolving cylinder 42 of lift actuating mechanism 30, one with revolving cylinder 42 is connected and one end can pass support platform 10 in proper order and stretch out the pivot 43 of hole 41 of stepping down, and one sets up revolving cylinder 42 one end's briquetting 44 is kept away from to pivot 43. The pressing block 44 is in a rectangular, oval or other shape, the outer edge of the pressing block 44 is smaller than the inner diameter of the abdicating hole 41, the pressing block 44 can pass through the abdicating hole 41, the rotating cylinder 42 drives the rotating shaft 43 to drive the pressing block 44 to rotate, the pressing block 44 is inconsistent with the abdicating hole 41, and the pressing block 44 cannot pass through the abdicating hole 41 to form the upper end limit of the positioning jig 20. In an initial state, the lifting driving mechanism 30 drives the driving plate 31 to descend, so that the upper end of the locking structure 40 is forced to be positioned below the supporting platform 10, or the supporting platform 10 is set to be high, and the locking structure has a positioning and supporting effect on the positioning jig 20; after positioning jig 20 placed in place, lift actuating mechanism 30 drives the locking device upper end, and pivot 43 and briquetting 44 in the hasp structure 40 pass the hole 41 of stepping down, hasp structure 40 sets up to setting for the height, and revolving cylinder 42 drives briquetting 44 and pushes down and can restrict positioning jig 20 and break away from supporting platform 10, and the clamping of completion to positioning jig 20 is fixed, reduces positioning jig 20 clamping side part through this clamping mode, and the overall arrangement design is more reasonable, and positioning jig 20's positioning accuracy has also been guaranteed to the little while of occupation space.

The upper end of the positioning jig 20 is provided with an abutting step 21 for the pressing block 44 to rotate and press downwards, the abutting step 21 enables the pressing block 44 to rotate more accurately, and the whole driving process is more reliable.
