[ detailed description ] embodiments

Example (b):

referring to fig. 1-2, the present embodiment is a plate clamping and positioning tool 100, which includes a base 1, a wedge 2 horizontally extending through the base 1, a fixing block 4 fixed on the base 1, a push rod 3 vertically extending through the fixing block 4, having a lower end abutting against the wedge 2 and driven by the wedge 2 to move up and down, a pressing plate 5 having a middle portion hinged to the fixing block 4 by a pin and an end driven by the push rod 3 to rotate, and an upper end of the push rod 3 connected to the fixing block 4 by an elastic member 6.

Base 1 is inside to be provided with horizontal distribution and through opening 11, vertical distribution and with the groove of accomodating (not sign in the picture) of opening 11 intercommunication, voussoir 2 sets up and carries out the horizontal motion in opening 11, be provided with in the fixed block 4 with accomodate the through-hole that the groove corresponds, catch bar 3 is in the through-hole with accomodate the inslot and carry out the up-and-down motion.

The upper surface of the wedge block 2 is a slope surface, and the end part of the wedge block is provided with a stop bulge 21 for blocking the end part of the slope surface. The lower surface of the push rod 3 is a slope structure which is matched and attached to the slope surface.

In this embodiment, two compressing plates 5 are arranged and symmetrically distributed on the fixing block 4.

An opening is formed in the push rod 3, and one end of the pressing piece 5 is inserted into the opening and overturns along with the up-and-down movement of the push rod 3.

The present embodiment further includes a cylinder 7 for driving the horizontal movement of the wedge 2. The air cylinder 7 drives the wedge block 2 to move horizontally, when the wedge block 2 moves leftwards, the push rod 3 moves upwards under the action of the inclined plane, one end of the pressing piece 5 rotates upwards under the jacking action of the push rod 3, and the other end of the pressing piece is driven to press downwards, so that a plate clamped between the base 1 and the pressing piece 5 is pressed; when the plate needs to be loosened, the air cylinder 7 drives the wedge block 2 to retract and realize stroke limiting through the blocking protrusion 21, at the moment, the push rod 3 is located at the lowest end of the slope surface, the push rod 3 descends, one end of the pressing piece 5 rotates downwards under the elastic pressing effect of the elastic reset block 7, the other end of the pressing piece 5 is driven to lift upwards, and therefore the pressing effect on the plate is loosened.
