the oil cylinder is fixed on the workbench, the upper end of a piston rod of the oil cylinder is in a cone frustum shape, the lower ends of the four arc-shaped sheets are combined together to form a horn shape, and the upper end of the piston rod of the oil cylinder is inserted in a pipe orifice formed by the lower ends of the four arc-shaped sheets.
The cover plate is fixed on the upper surface of the base plate through screws, and the base plate is fixed on the workbench through screws.
The tenon is clamped between the chassis and the cover plate.
The tenon is in a square strip shape.
And a plurality of small anti-slip teeth are formed on the outer diameter surface of the arc-shaped inner supporting block.
The utility model has the beneficial effects that:
the outer ring is tightly supported from the inner diameter surface of the outer ring, and then the outer ring is drilled through the tapping cutter, so that the roundness of the outer ring after drilling can be ensured.

In the figure: 1. a spring; 2. a work table; 3. a chassis; 4. a cover plate; 5. an outer ring; 6. a support member; 7. and an oil cylinder.
Detailed Description
Example (b): as shown in fig. 1 to 3, the bearing ring drilling fixture comprises a spring 1 and a workbench 2, wherein a workbench circular hole 21 is formed on the workbench 2, four square slots 31 are uniformly distributed on a chassis 3, the chassis 3 is fixed on the workbench 2, and a cover plate 4 covers the surface of the chassis 3 and is fixed on the chassis 3;
the chassis 3, the cover plate 4 and the workbench round hole 21 are coaxial, and the structure of each support part 6 is as follows: the outer diameter surface of the arc-shaped sheet 61 is provided with a tenon 62 and an arc-shaped inner supporting block 63; the four supporting pieces 6 are inserted in the central holes of the base plate 3 and the cover plate 4, the tenon 62 is inserted in the square slot 31, one end of the spring 1 is pressed on one side of the square slot 31, the other side of the spring is pressed on the tenon 62, the spring 1 is arranged in the square slot 31, and the outer diameter surface of the arc-shaped inner supporting block 63 is opposite to the inner diameter surface of the outer ring 5;
the oil cylinder 7 is fixed on the workbench 2, the upper end of a piston rod of the oil cylinder 7 is in a cone frustum shape, the lower ends of the four arc-shaped sheets 61 are combined together to be in a horn shape, and the upper end of the piston rod of the oil cylinder 7 is inserted and sleeved in a pipe opening formed by the lower ends of the four arc-shaped sheets 61.
The cover plate 4 is fixed on the upper surface of the base plate 3 through screws, and the base plate 3 is fixed on the workbench 2 through screws.
The tongue 62 is clamped between the base plate 3 and the cover plate 4.
The tenon 62 is a square strip.
The outer diameter surface of the arc-shaped inner supporting block 63 is provided with a plurality of small anti-slip teeth.
The working principle is as follows: in an initial state, the piston rod of the oil cylinder 7 retracts, the arc-shaped sheets 61 of the four supporting pieces 6 are combined into a tubular shape, the outer ring 5 of the bearing is placed on the cover disc 4, the four arc-shaped inner supporting blocks 63 are located in a center hole of the outer ring 5, then the piston rod of the oil cylinder 7 extends out, the piston rod of the oil cylinder 7 drives the four supporting pieces 6 to be opened, the four arc-shaped inner supporting blocks 63 are tightly supported on the inner diameter surface of the outer ring 5, and then the outer ring 5 is drilled by the tapping cutter.
After drilling is finished, a piston rod of the oil cylinder 7 retracts, the four supporting pieces 6 retract inwards under the action of the elastic force of the spring 1, and the outer ring 5 of the bearing can be taken away.
This practical is trapezoidal when the outer lane is drilled, and it is being propped by bracer 63 in four arcs always, and outer lane non-deformable guarantees the circularity after the outer lane drilling processing like this.
