Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
Embodiment
As shown in Figure 1, a kind of v block with substrate hold-down function, including v block 1 and hold-down mechanism, hold-down mechanism include solid
It is scheduled on the column 2 of v block opening face two sides, sliding sleeve 3 is slidably connected on column 2, is fixed with lifter plate 7 between two sliding sleeves 3,
The middle part of lifter plate 7 is connected with pin shaft by bracket fixed-axis rotation, and cam disc 11 is fixed on pin shaft, in cam disc 11
Axis two sides are symmetrically hinged with connecting rod 10, and 10 end of connecting rod is hinged with mandril 9, the connection of two connecting rods 10 and cam disc 11
It puts with the rotation center of cam disc 11 on the same line, and is fixed with driving lever 12 on the pin shaft of the connection of cam disc 11, mandril 9 is sliding
On the dynamic guide sleeve 8 being plugged on lifter plate 7, and it is directed toward sliding sleeve 3, mandril 9 is vertical with the plane of symmetry of v block 1, corresponding on sliding sleeve 3
The signified position of mandril 9 offers through-hole, and mandril 9 slides through the through-hole on sliding sleeve 3 and contacts with column 2, under lifter plate 7
Surface is connected with pressing plate 4 by guide rod 5, and the through slot that cam disc 11 passes through on lifter plate 7 is contacted with the upper surface of pressing plate 4, pressing plate 4
Spring 6 is connected between lifter plate 7, and spring 6 is socketed on guide rod 5.
In the present embodiment, when using v block 1, driving lever 12 is rotated counterclockwise first, driving lever 12 drives cam disc 11 synchronous
It is rotated counterclockwise around pin shaft, until cam disc 11 do not contact with pressing plate 4, effect to the not applied force of pressing plate 4, rotation cam disk
While 11, connecting rod 10 and the tie point of cam disc 11 is driven to rotate counterclockwise, connecting rod 10 applies pulling force to mandril 9 and makes mandril
9 along guide sleeve 8 far from sliding sleeve 3,9 column 2 of mandril does not apply extruding force at this time, and sliding sleeve 3 can be slided with respect to column 2, promoted rise
Plate 7 is dropped, workpiece is placed on v block 1, then lifter plate 7 is moved down to and made 4 contact workpiece of pressing plate, rotates clockwise and dials
