When the positioning column 12 is matched with the positioning hole 1, the position of the framework 41 is positioned, and as the diameter of the circumscribed circle of the section of the prismatic column 13 is smaller than the aperture of the auxiliary hole 11, a certain error margin is reserved for the matching of the prismatic column 13 and the auxiliary hole 11, the clamping condition when the prismatic column 13 is inserted into the auxiliary hole 11 is reduced, and meanwhile, the error margin of the prismatic column 13 and the auxiliary hole 11 meets the precision requirement of the reference hole 42.

When the framework 41 needs to be clamped or disassembled, an operator pulls out the limiting pin 26 and rotates the base frame 2, so that the base frame 2 is separated from the position corresponding to the framework 41, and the obstruction caused by the movement of the framework 41 is reduced.

As shown in fig. 3 and 7, the positioning column 12 and the prismatic column 13 are both in threaded connection with the workbench 43, concave holes 3 corresponding to the side edges of the framework 41 are formed in the workbench 43, the central column 31 is inserted into each concave hole 3 of the workbench 43, and each central column 31 is tangent to the framework 41. When the positioning hole 1 and the two auxiliary holes 11 are machined, an operator unscrews the positioning column 12 and the prismatic column 13, then places the framework 41 on the workbench 43, inserts the central column 31 into the concave hole 3, positions the framework 41, and then the operator can machine the positioning hole 1 and the auxiliary holes 11; after the positioning hole 1 and the auxiliary hole 11 are machined, an operator turns the framework 41 to enable the positioning column 12 and the prismatic column 13 to be respectively inserted into the positioning hole 1 and the auxiliary hole 11, so that the reference hole 42 can be directly machined, the process is compact, and the machining efficiency is improved. Meanwhile, due to the positioning effect of the central column 31 on the framework 41, on one hand, the time for repeated debugging and tool setting of an operator in the process of machining the positioning hole 1 and the auxiliary hole 11 is saved, on the other hand, the offset of the position of the framework 41 after being turned is reduced, and the machining precision of the reference hole 42 is increased.
