Detailed Implementation

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] like Figure 1 , Figure 2 As shown, a drilling tool includes a clamping device 1, several fastening blocks 2, several sliding grooves 3, and a turntable 6; the turntable 6 has several sliding grooves 3 arranged radially, and several fastening blocks 2 are respectively connected in different sliding grooves 3; the clamping device 1 includes a handle 11, a pressure pad 12, and a connecting post 13, the pressure pad 12 is provided with a through hole, the connecting post 13 is connected to the slot hole of a sliding groove 3, and the handle 11 passes through the through hole of the pressure pad 12 and is connected to the connecting post 13.

[0023] Furthermore, the fastening block 2 is fixed to the relative position of the slide groove 3 by bolts.

[0024] Furthermore, the fastening block 2 is an L-shaped component, with its long side connected to the sliding groove 3 and its short side abutting against the bearing ring workpiece 5. The fastening block 2 serves to fix the bearing ring workpiece that requires drilling.

[0025] Furthermore, the fastening block 2 is a T-shaped part, the long side of the T-shaped part is connected to the slide groove 3, and the short side of the T-shaped part abuts against the bearing ring workpiece 5.

[0026] Furthermore, the top end of the bearing ring workpiece 5 comes into contact with the pressure pad 12. The pressure pad 12 can press the bearing ring workpiece 5 tightly.

[0027] Furthermore, there are three slide grooves 3, which are arranged at 120-degree intervals with the center of the turntable 6 as the center. There are also three fastening blocks 2, which are arranged one-to-one with the three slide grooves. The slide grooves 3 include a first slide groove 31, a second slide groove 32, and a third slide groove 33. The first slide groove 31 and the second slide groove 32 are fixedly connected to the turntable 5, and the connecting post 13 is fixedly connected to the third slide groove 33, and the connecting post 13 is located in the slot of the third slide groove 33. Since the three slide grooves 3 are arranged at 120-degree intervals with the center of the turntable 6 as the center, the three fastening blocks are also arranged at 120-degree intervals with the center of the turntable 6 as the center. The bearing ring workpiece 5 abuts against the three spaced fastening blocks 2, which can prevent the bearing ring workpiece 5 from being squeezed and deformed during the drilling process.

[0028] Furthermore, it also includes a cylinder 91 and a cylinder rod 92, wherein the cylinder 91 is connected to the third slide groove 33 via the cylinder rod 92.

The handle 11 is screwed into the connecting post through the pressure pad 12, and this configuration allows for adjustment of the height of the pressure pad 12.

[0030] Furthermore, the length of the pressure pad 12 is greater than the diameter of the bearing ring workpiece 5. This greater length ensures that the bearing ring workpiece will not be displaced during drilling. By rotating the handle 11, a downward force can be applied to the pressure pad 12, ensuring that the pressure pad 12 can press firmly against the bearing ring workpiece 5. At this time, the bearing ring workpiece 5 is clamped by the pressure pad 12 and the fastening block 2, preventing it from tilting or being displaced during drilling.

[0031] After adjusting the position of the fastening block 2, fix the fastening block 2 to the slide groove 3 with bolts. Place the bearing ring workpiece 5 on the fastening block 2, and place the pressure pad 12 on the bearing ring workpiece 5. Pass the handle 11 through the through hole in the pressure pad 12 and screw it into the connecting column 13. Adjust the position of the pressure pad by tightening the handle until the pressure pad 12 can press the bearing ring workpiece 5 tightly. At this time, the bearing ring workpiece 5 is clamped by the fastening block 2 and the pressure pad 12. Use two drill bits to drill holes in the bearing ring workpiece 5 simultaneously. The bearing ring workpiece 5 will not deform or shift vertically during the drilling process, thus avoiding deviation in the drilling position.
