Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "bottom" and "top," "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
Example (b): a high-precision flange fixing tool clamp is shown in figure 1 and comprises a bottom plate 1, wherein a center positioning pin 11 is vertically arranged on the bottom plate 1, and the center positioning pin 11 is located at the center of the bottom plate 1. When the flange is fixed, the center positioning pin 11 is inserted into the inner hole of the flange.
As shown in fig. 1, a support block 12 is fixed on the bottom plate 1 by bolts, and the support block 12 is mainly used for supporting the bottom surface of the flange.
As shown in fig. 1 and 2, a pair of edge positioning pins 14 is vertically disposed on the bottom plate 1, and the edge positioning pins 14 are symmetrically arranged with respect to the center positioning pin 11. The edge locator pins 14 may be inserted into holes in the flange edge when the flange is secured.
As shown in fig. 1, a pair of mounting posts 13 are vertically disposed on the bottom plate 1, the mounting posts 13 are arranged in a central symmetry manner about the center positioning pin 11, and the mounting posts 13 and the edge positioning pins 14 are arranged in a cross manner. The mounting post 13 is sleeved with a sleeve 131, the sleeve 131 and the mounting post are connected in a sliding manner, and a pressing plate 132 is horizontally arranged outside the sleeve 131. The mounting post 13 is sleeved with a spring 133 in a stretching state, an inner cavity for accommodating the spring 133 is formed in the sleeve 131, the bottom end of the spring 133 is fixed on the mounting post 13, and the top end of the spring 133 is fixed with the top surface of the inner cavity of the sleeve 131. The top of the mounting post 13 is threadedly connected with a nut. When the flange is fixed, the spring 133 is contracted to make the sleeve 131 have a downward moving state, so that the pressing plate 132 is ensured to press the flange, and the flange is fixed more firmly.
As shown in fig. 1 and 2, a first mounting plate 2 and a second mounting plate 3 are vertically disposed on the bottom plate 1, and the first mounting plate 2 and the second mounting plate 3 are symmetrically arranged about a center positioning pin 11. The top end of the first mounting plate 2 is rotatably connected with a turning plate 21, and the end part of the turning plate 21 far away from the first mounting plate 2 is provided with a limit groove 211.
