As the utility model discloses a improve again, the relative lateral wall face of left and right sideslip pole is flat straight face.
Both sides set up to straight face one and help carrying out the centre gripping to the part, and also be convenient for carry out the projection measurement to the distance between the left and right sideslip pole, can obtain the size of part.
As a further improvement, the left and right transverse rods are perpendicular to the side ends of the clamping plate and the supporting plate which are hinged. The left screw and the right screw can be conveniently installed and rotated by the arrangement.
As another improvement of the present invention, the clamping plate is formed in a square frame shape by fastening four quadrangular prisms by bolts and a hollow area is formed therein. So that the left and right transverse moving rods and the left and right screw rods can be conveniently installed.
As another improvement of the present invention, the edge of the supporting plate hinged to the bottom plate is provided with a right-angle folded edge.
Through setting up the right angle hem, help steadily placing of anchor clamps, secondly when anchor clamps are folded, can be so that leave the interval between bottom plate and the backup pad, this interval is used for placing the grip block after folding.
As a further improvement of the present invention, the bottom plate is also square and forms a square hollow area therein. Thereby, the light transmitting area between the bottom plate and the clamping plate can be kept equal.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in fig. 1-3, the projection measurement fixture in this embodiment includes a bottom plate 1, a supporting plate 2, and a clamping plate 3, wherein the bottom plate 1 and the clamping plate 3 are both square frames, a square hollow area is formed in the middle of the bottom plate 1 and the clamping plate 3, one end of the bottom plate 1 and one end of the clamping plate 3 are hinged to two ends of the supporting plate 2, and the three are C-shaped; a right-angle folded edge 21 is arranged at the edge end of the supporting plate 2 hinged with the bottom plate 1; the chucking plate 3 is formed in a square frame shape by four quadrangular prisms fastened by bolts.
Because the bottom plate 1 and the clamping plate 3 are both square frames, the turnover angle ranges of the bottom plate and the clamping plate are 0-270 degrees, and the turnover directions of the bottom plate and the clamping plate are opposite.
And because of the existence of the right-angle-shaped folding edge 21, the bottom plate 1 can keep a certain distance with the supporting plate 2 when being overturned to be parallel to the supporting plate 2, and the distance can be used for placing the clamping plate 3.
The clamping plate 3 is in a square frame shape formed by fastening four quadrangular prisms through bolts, and two opposite side wall surfaces in the hollow area of the clamping plate 3 are provided with sliding grooves 33; two quadrangular prism-shaped left and right traverse rods 31 arranged side by side are arranged in the hollow area of the clamping plate 3, and two ends of the left and right traverse rods 31 can be slidably embedded into the sliding grooves 33.
A left screw 32 and a right screw 32 are fixed on two side ends of the clamping plate 3 parallel to the left transverse rod 31 and the right transverse rod 31, and one end of the left screw 32 and one end of the right screw 32 are respectively abutted against the left transverse rod 31 and the right transverse rod 31; wherein the left and right screw rods 32 and the left and right traverse rods 31 are kept vertical; and the left and right traverse rods 31 are perpendicular to the edge ends of the holding plate 3 hinged with the supporting plate 2.
When the clamp is folded, the projection plate 3 is firstly turned over to be attached to the supporting plate 2, and then the bottom plate 1 is turned over to be attached to the projection plate 3, so that the three are tightly attached; wherein the width of the right-angle fold 21 should preferably be adapted to the sum of the thicknesses of the projection plate 3 and the base plate 1.
When a workpiece is clamped, the workpiece is placed between the left and right traverse rods 31, and the left and right screw rods 32 are rotated to push the left and right traverse rods 31 to move, thereby generating a clamping force on the workpiece.
Since the clamping plate is a square frame formed by fastening four quadrangular prisms together by bolts, the installation of the left and right traverse bars 31 can be facilitated.
The above description is only for the preferred embodiment of the present invention and should not be taken as limiting the invention, and any modifications, equivalent replacements and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
