DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0029] like Figure 1 and Figure 2As shown, a drilling device includes: a base 20, the base 20 is a rectangular plate, and support legs are respectively installed at the four corners of the bottom of the base 20. A motor is fixedly connected to the bottom center of the base 20, and a drilling machine 21 is also fixedly connected to one side wall of the base 20. The motor and the drilling machine 21 are both electrically connected to the corresponding power supply. The model used by the drilling machine 21 is the same model as the drilling equipment used in the prior art (publication number: CN219786629U). This is the existing technology, so it will not be described here.

[0030] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, a rotation structure is provided at the top of the base 20 for fixing the bearing ring. The rotation structure includes: a rotating shaft 30, a rotating plate 31, a solid column 34, a stud 35 and a pressure plate 36. The rotating shaft 30 is rotatably connected to the top center of the base 20, the rotating plate 31 is fixedly connected to the top of the rotating shaft 30, the solid column 34 is symmetrically fixedly connected to the top of the rotating plate 31, the stud 35 is threadedly connected to the top of the solid column 34, and the pressure plate 36 is rotatably connected to the wall of the solid column 34. The same stud 35 and pressure plate 36 are provided on the top of each solid column 34.

[0031] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The cam 35 is provided with a screw thread on the bottom of the cam 35 and the screw thread on the bottom of the cam 35 is provided with a screw thread on the bottom of the cam 35. The cam 35 is provided with a screw thread on the bottom of the cam 35 and the screw thread on the bottom of the cam 35 is provided with a screw thread on the bottom of the cam 35. The cam 35 is provided with a screw thread on the bottom of the cam 35 and the screw thread on the bottom of the cam 35 is provided with a screw thread on the bottom of the cam 35.

[0032] During specific use, the bearing ring of the required hole is first put on the fixed column 34, and after the placement is completed, the stud 35 is screwed on the wall of the fixed column 34. The stud 35 will drive the pressure plate 36 to fix the bearing ring on the wall of the fixed column 34, and then the motor at the bottom of the base 20 will be turned on. At this time, the motor will drive the rotating shaft 30 to rotate 180 degrees. The rotating shaft 30 can drive the rotating plate 31 and all the structures on the wall of the rotating plate 31 to rotate at the same time. The supporting rod 32 can drive the ball 33 to roll along the top of the base 20 when the rotating plate 31 rotates. The symmetrical fixed columns 34 will exchange positions as the rotating plate 31 rotates. At this time, the fixed column 34 with the bearing ring fixed will rotate to the same side of the drilling machine 21, and then the power of the drilling machine 21 is turned on to drill holes. The machine 21 will drill holes in the bearing rings fixed on the solid column 34. When the drilling machine 21 is drilling holes in the bearing rings on the wall of the solid column 34, the next batch of bearing rings to be drilled are fixed on the wall of another idle solid column 34 in the same way. Then, after the drilling of the bearing rings is completed, the motor at the bottom of the base 20 controls the rotating shaft 30 to rotate 180 degrees to exchange the positions of the processed and unprocessed bearing rings. The drilling machine 21 will drill holes in the unprocessed bearing rings. At this time, the processed bearing rings can be unscrewed by unscrewing the studs 35 so that the pressure plate 36 no longer fixes the bearing rings to the wall of the solid column 34. Then, the processed bearing rings can be removed and the bearing rings to be drilled are placed on them for drilling.

[0033] In summary, the drilling efficiency of the device can be improved by setting up a rotation structure. The rotation structure drives the bearing rings to be processed to rotate in position through the fixed column 34 that can interchange positions, so that while processing the bearing rings, the position of the next batch of bearing rings to be processed can be fixed and the previous batch of bearing rings that have been processed can be removed. Therefore, this solution has a higher drilling efficiency when drilling large quantities of bearing rings.

[0034] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5As shown, the top of the rotating plate 31 is also provided with a soft pressure structure, which includes a split plate 40, a slide groove 41, a slider 42 and a follower plate 43. The split plate 40 is fixedly connected to the middle section of the top of the rotating plate 31, and the slide groove 41 is symmetrically opened on the two side walls of the split plate 40. The slider 42 is slidably connected in the slide groove 41, and the follower plate 43 is fixedly connected to the wall of the slider 42. The same slider 42 is provided in each slide groove 41, and the wall of each slider 42 is provided with the same follower plate 43. The split plate 40 is a rectangular plate, and the slide groove 41 is a notch with an isosceles trapezoidal cross-section. The slide groove 41 can adapt to the slider 42 to slide vertically up and down, and the top of the follower plate 43 can Aligned with the top of the solid column 34, the soft pressure structure also includes a rotation groove 44, a rotation column 45 and a compression spring 46. The rotation groove 44 runs through the top of the follower plate 43, and the rotation column 45 is rotatably connected in the rotation groove 44. The bottom of the rotation column 45 is fixedly connected to the top of the stud 35, and the compression spring 46 is fixedly connected to the bottom of the stud 35. The bottom of the compression spring 46 is fixedly connected to the top of the pressure plate 36. The rotation groove 44 can adapt to the rotation of the rotation column 45. The rotation column 45 is annular, the rotation groove 44 is a circular groove with an I-shaped cross-section, the rotation column 45 is a cylinder with an I-shaped cross-section, and the compression spring 46 is spring-shaped. The inner wall surface of the rotation column 45 and the compression spring 46 cavity can adapt to the outer arc surface size of the solid column 34;

[0035] In actual use, when the stud 35 is screwed into the wall of the fixed column 34, the stud 35 will drive the rotating column 45 to rotate synchronously in the rotating groove 44. The stud 35 will also drive the compression spring 46 and the pressure plate 36 to rotate on the wall of the fixed column 34. The follower plate 43 and the follower plate 43 will move downward along the slide groove 41 as the stud 35 is screwed. When the pressure plate 36 contacts the top of the bearing ring to be fixed, the compression spring 46 will push the pressure plate 36 toward the top of the bearing ring.

[0036] In summary, by setting up a soft pressure structure, the pressure plate 36 can be pushed toward the top of the bearing ring through the elastic compression spring 46 when fixing the bearing ring. Compared with conventional hard pressure, this solution will not damage the bearing ring.

[0037] Working principle: first put the bearing ring of the required hole on the solid column 34, and screw the stud 35 on the wall of the solid column 34 after placement. The stud 35 will drive the pressure plate 36 to fix the bearing ring on the wall of the solid column 34, and then turn on the motor at the bottom of the base 20. At this time, the motor will drive the rotating shaft 30 to rotate one hundred and eighty degrees. The rotating shaft 30 can drive the rotating plate 31 and all the structures on the wall of the rotating plate 31 to rotate at the same time. The supporting rod 32 can drive the ball 33 to roll along the top of the base 20 when the rotating plate 31 rotates. The symmetrical solid columns 34 will interchange positions as the rotating plate 31 rotates. At this time, the solid column 34 with the bearing ring fixed will rotate to the same side of the drilling machine 21, and then the power of the drilling machine 21 is turned on, and the drilling machine 21 is The bearing rings fixed by the solid column 34 will be drilled. When the drilling machine 21 drills the bearing rings on the wall of the solid column 34, the next batch of bearing rings that need to be drilled will be fixed on the wall of another idle solid column 34 in the same way. Then, after the drilling of the bearing rings is completed, the motor at the bottom of the base 20 controls the rotating shaft 30 to rotate 180 degrees to interchange the positions of the processed and unprocessed bearing rings. The drilling machine 21 drills the unprocessed bearing rings. At this time, the processed bearing rings can be unscrewed by unscrewing the studs 35 so that the pressure plate 36 no longer fixes the bearing rings to the wall of the solid column 34. Then the processed bearing rings are removed and the bearing rings that need to be drilled are placed on them for drilling, and the process repeats.
