Specifically, when workpiece 200 is positioned over positioning plate 120, limited block 123 can be contained in link slot 210 and with connecting
The madial wall of access slot 120 abuts against, and to be pre-positioned to 200 relative positioning plate 120 of workpiece, avoids on the second inclined-plane 132
Workpiece 200 is caused to be moved relative to 120 occurred level of positioning plate during abutting extruding with the first inclined-plane 220, so that
Workpiece 200 can more stably be placed on positioning plate 120.
It is pointed out that the bottom surface of workpiece 200 is provided with convex block (figure is not marked).It can also offer and keep away on positioning plate 120
Position groove 124.Specifically in the present embodiment, bit-avoiding slot 124 is distributed in the both sides of the Z-direction of positioning plate 120.Bit-avoiding slot 124 is used for
It is engaged with convex block, so as to increase the relative area that workpiece 200 is contacted with positioning plate 120 so that workpiece 200 can be fixed
More stably placed on the plate 120 of position.
Further, as shown in fig. 6, one end of connecting plate 170 can also offer guide groove 171.Pushing block 140 and guide groove
171 madial wall slides against.By the setting of guide groove 171, slip of the sliding block 130 in straight slot 121 can be given to provide one
Fixed guiding role so that the pressure head 131 for being connected to one end of sliding block 130 can be exactly even under the drive of sliding block 130
Move along set direction in access slot 210, so that the second inclined-plane 132 can preferably abut and extrude the first inclined-plane 220, carry
Fixed effect of the high workpiece 200 on positioning plate 120.
Above-mentioned locking fixture 100, passes through the 133 phase interworking of the 3rd inclined-plane on the 4th inclined-plane 141 and sliding block 130 of pushing block 140
The direction of motion of the sliding block 130 in straight slot 121 can be changed by closing the wedge structure formed so that actuator 150 is to pushing block 140 logical
The driving force moved in the first direction in groove 121 passes to sliding block 130, is converted into sliding block 130 in straight slot 121 in a second direction
Movement so that the second inclined-plane 132 is abutted with the first inclined-plane 220, and then workpiece 200 is fixed on positioning plate 120.Cause
This, above-mentioned locking fixture 100 avoids the troublesome operation that traditional 200 the right and left of hand-operated clamping workpiece is brought, and inclined wedge
Simple in structure, the movement travel of clamping is small, have it is easy to operate, the characteristics of occupying little space.
Each technical characteristic of above example can be combined arbitrarily, to make description succinct, not to above-described embodiment
In each technical characteristic it is all possible combination be all described, as long as however, lance is not present in the combination of these technical characteristics
Shield, is all considered to be the scope of this specification record.
