Be connected to pallet on the piston shaft of linear oil cylinder by face, and the other end is hinged with lever medial launder；Lever two ends fluting respectively with even
Bar one end is hinged, and fluting is contacted all the time with the shifting block of pressing plate in the middle of connecting rod, and the other end is slided in pressing plate seat；With pressure in the middle of pressing plate
Panel seat is hinged；Mandrel is gap cooperation with positioning seat, locating slide sleeve, and pallet, locating slide sleeve, lever are sleeved on mandrel successively
On, as linear oil cylinder piston rod movement moves up and down.
Due to using technical scheme as described above, the utility model has following superiority：The utility model structure is tight
Gather, it is easy to operate, hydraulic clamp be need to only start and 2 self-centering positioning and automatic impaction in same blank hole are capable of achieving；Using
Multiple little springs and guide post structure, realize 2 self-centering locating tensioning workpiece.
Brief description of the drawings
Fig. 1 is the overlooking the structure diagram of a kind of Internal hole positioning of the utility model and hold-down gear；
Fig. 2 is the B-B rotation cross-sectional views of Fig. 1.
Specific embodiment
The utility model is further described below in conjunction with the accompanying drawings.As shown in figure 1, a kind of 2 self-centerings and automatic
Hold-down gear, including it is lever 2, connecting rod 3, mandrel 4, locating slide sleeve 5, ejector pin 6, spring 7, baffle plate 8, positioning seat 9, body 10, straight
Line oil cylinder 11, guide post 12, pallet 13, central spindle of the spring（14）, spring 15, pressing plate seat 16, bearing pin 17, pressing plate 18；Locating slide sleeve 5
It is concentric locking collar, external cylindrical surface has along the circumferential direction been uniformly arranged two grooves, and bottom land is slided into the conical surface, external cylindrical surface with positioning seat 9
Coordinate, inner cylinder face is slidably matched with mandrel 4；Positioning seat 9 has along the circumferential direction been uniformly arranged two circular holes, is slided with ejector pin 6
Coordinate.
Ejector pin 6 is totally 2, cylinder, and afterbody is slidably matched with the groove of locating slide sleeve 5, afterbody inclined-plane and the bottom land of locating slide sleeve 5
Taper-face contact, the cylinder first half of ejector pin 6 sets gradually one and a half months hole and an aperture in same position, and first quarter moon hole is used to keep away
Allow baffle plate 8, aperture is used to install spring 7, under spring 7 and the collective effect of baffle plate 8, make the afterbody inclined-plane of ejector pin 6 and locating slide sleeve 5
The bottom land conical surface contacts do not separate all the time；Pilot hole and spring mounting hole are bored in bottom land end, and guide post 12 is slided with locating slide sleeve 5 matches somebody with somebody
Close, the one end of central spindle of the spring 14 is threadedly coupled with pallet 13, and the other end is inserted in the spring mounting hole of locating slide sleeve 5.
