【Detailed ways】

The following will describe in detail with reference to specific embodiments.

The present utility model will be further described in detail below in conjunction with the specific embodiments. It should be emphasized that the following description is exemplary only, and is not intended to limit the scope of the present invention and its application.

As shown in Figure 1-3, a special tool for drilling hinge thrust shoes to install positioning holes on bearing caps, including set screws 1; positioning angle steel 2; shape base 3; limit baffle 4; limit protrusion Block 5; inner hexagon fastening bolt 6; fixed hinge seat 7, the left side wall of the positioning angle steel 2 is provided with a threaded hole matched with the set screw 1, and a shape base is provided on the right side of the top of the bottom plate of the positioning angle steel 2 3. The right side of the shape base 3 is provided with a standing limit baffle 4, the left side of the limit baffle 4 is also provided with a limit bump 5, the positioning angle steel 2 and the shape base 3 and the shape base 3 and the limit baffle 4 are connected by the inner hexagon fastening screws 6, the limit baffle 5 and the limit bump 5 are connected by the inner hexagon fastening bolts 6, the shape base 3 is semicircular, the shape The back of the base 3 is also provided with two circular through holes with half-pipe threads. The two circular threaded through holes of the shape base 3 are each provided with a hollow screw with a positioning hole. The corners are arc-shaped, and the fixed hinge seat 7 is composed of a rectangular hollow bottom plate 7-1 and two L-shaped cylindrical steel bars 7-2.
