DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] Reference Figure 1-5 A steel plate drill with chamfering function includes a main body 1, a drilling part 2 is fixedly connected to the bottom of the main body 1, a connecting part 3 is fixedly connected to the top of the main body 1, an auxiliary ring 4 is fixedly connected to the side of the main body 1, and a chamfering part 6 is provided at the bottom of the auxiliary ring 4 through an adjusting mechanism 5. Specifically, the adjusting mechanism 5 can facilitate the adjustment of the position of the chamfering part 6 so that the chamfering part 6 can be chamfered and ground during the drilling process. A limiting mechanism 7 is provided between the chamfering part 6 and the drilling part 2. Specifically, the limiting mechanism 7 can ensure that when the main body 1 rotates, the relationship between the chamfering part 6 and the drilling part 2 can be stable, and the rotation of the drilling part 2 can drive the chamfering part 6 to rotate. The side of the chamfering part 6 is provided with a limiting block 9 through an auxiliary mechanism 8. Specifically, the auxiliary mechanism 8 can facilitate the limiting block 9 to limit the chamfering part 6, thereby ensuring that the chamfering is not excessive during grinding.

[0026] This program has the following working process:

[0027] When it is necessary to use a steel plate drill, first connect the main body 1 to the machine through the connecting part 3, and then adjust the height of the chamfering part 6 through the adjusting mechanism 5 on the auxiliary ring 4. During the adjustment process, the connection between the chamfering part 6 and the drilling part 2 is stabilized by the limiting mechanism 7. After the adjustment, the chamfering part 6 is stabilized, and then the machine is started to drill the steel plate through the connecting part 3. After drilling, the edge of the drilled hole can be chamfered and polished through the chamfering part 6 to make the hole chamfered. When grinding the chamfer, it is limited by the limiting block 9 to prevent excessive chamfering. The auxiliary mechanism 8 facilitates the use of the limiting block.

[0028] According to the above working process, we can know that:

[0029] When it is necessary to drill a hole in a steel plate, the chamfering part 6 can be adjusted first, and then the machine can be started to drive the main body 1 to rotate, so that the drilling part 2 can be used to drill a hole conveniently, and the chamfering part 6 can be used for chamfering, so that the surface of the hole can be chamfered while drilling.

[0030] Furthermore, the adjustment mechanism 5 includes two insertion rods 501 fixedly connected to the bottom of the auxiliary ring 4, and the top of the chamfered portion 6 is rotatably connected to an L-shaped anti-movement block 503 through a torsion spring shaft 502. A plurality of insertion grooves 504 are provided on the surface of the insertion rod 501, and the anti-movement block 503 is located inside the adjacent insertion grooves 504. Specifically, when the chamfered portion 6 needs to be adjusted, the anti-movement block 503 is first rotated so that the anti-movement block 503 is disengaged from the insertion groove 504, and then the chamfered portion 6 is slid up and down. After adjustment, the anti-movement block 503 is released, and the anti-movement block 503 is reinserted into the adjacent insertion groove 504 through the torsion spring shaft 502, so that the position of the chamfered portion 6 can be easily adjusted.

[0031] Furthermore, four stabilizing blocks 505 are fixedly connected to the bottom of the auxiliary ring 4, and the stabilizing blocks 505 are passed through the top of the chamfered portion 6. Specifically, the stabilizing blocks 505 can prevent the chamfered portion 6 from rotating and misaligned during the adjustment of the chamfered portion 6, and when the chamfered portion 6 is in use, the stability is improved by inserting the stabilizing blocks 505 into the inside of the chamfered portion 6, so that the chamfered portion 6 can rotate with the main body 1.

[0032] Furthermore, the limiting mechanism 7 includes a plurality of limiting rods 701 fixedly connected to the top of the drilling portion 2, and the limiting rods 701 are passed through the bottom of the chamfering portion 6. Specifically, during the up and down movement and adjustment of the chamfering portion 6, the limiting rods 701 can be inserted into the bottom of the chamfering portion 6 to increase the stability between the chamfering portion 6 and the drilling portion 2, so that the rotation of the drilling portion 2 can more stably drive the chamfering portion 6 to rotate.

[0033] Furthermore, a plurality of auxiliary rods 702 are fixedly connected to the bottom of the chamfering portion 6, and the auxiliary rods 702 are passed through the top of the drilling portion 2. Specifically, when the chamfering portion 6 is moved up and down for adjustment, the auxiliary rods 702 can conveniently stabilize the chamfering portion 6 inside the drilling portion 2, thereby conveniently enhancing the connection between the chamfering portion 6 and the drilling portion 2, and ensuring that the chamfering portion 6 can be stably driven when the drilling portion 2 rotates.

[0034] Furthermore, the auxiliary mechanism 8 includes a rotating circle 801 opened on the side of the chamfering part 6, the limit block 9 is rotatably connected to the rotating circle 801, and a rubber pad 802 is fixedly connected between the top of the limit block 9 and the rotating circle 801. Specifically, when the drilling part 2 and the chamfering part 6 are used, the rotating circle 801 can be easily passed so that the limit block 9 will not rotate with the chamfering part 6. Therefore, when drilling and chamfering to a certain extent, the limit block 9 contacts the steel plate, thereby conveniently reminding that the chamfering is completed, ensuring that the chamfering degree is controllable, and the rubber pad 802 can prevent the limit block 9 from being damaged by friction with the top of the rotating circle 801.

[0035] In summary, when it is necessary to drill a hole in a steel plate, the chamfered portion 6 can be conveniently adjusted, and then the chamfered portion 6 can be used to chamfer the edge of the hole when drilling, and the chamfered portion 6 can be made more stable.
