Description

Reaming bit structure of drilling machine

This creation is about a drill bit of a drilling machine, especially a drill bit structure of a drilling machine that can perform reaming and drilling without changing the drill bit.

A drilling machine is a large machine tool used for drilling shafts in mines, or tunnel drilling and cutting. The drilling work of a drilling machine is usually a two-stage operation. After the first drilling, the expansion is replaced The drill bit is used for the second reaming and cutting operation. However, when the drill bit is removed to replace the reaming bit, the hole wall of the drilled hole will collapse due to the soft soil, causing the drilling work to fail. Moreover, the action of changing the drill bit between the secondary drilling and cutting is time-consuming and laborious, so it is quite a waste of time in engineering.

As mentioned above, there are still quite a few problems in the drilling of boring machines. Therefore, in view of the above-mentioned problems, the creator of this case is eager to improve and innovate. After years of painstaking research, he has finally successfully developed the drill The reaming bit structure of the excavator.

In order to solve the problems of the prior art, one purpose of this creation is to provide a reaming drill bit structure of a drilling machine that can perform reaming and cutting operations without changing the drill bit.

In order to solve the problems of the prior art, another purpose of this creation is to provide a reaming drill bit structure of a drilling machine that uses a control panel to adjust the penetration and retraction of the flank bit of the side edge of the bit.

In order to achieve the above purpose, the reaming bit structure of the drilling machine provided by this creation mainly includes a bit body, a control panel and a plurality of flank bits. One side of the bit body is provided with a plurality of grinding machines, and the bit body is relatively provided with The other surface of the grinders is provided with a plurality of through grooves extending from the position of the drill body adjacent to the center to the periphery.

The side-wing bits are respectively arranged in the through grooves. Each of the side-wing bits includes a guide seat and a grinding drill bit. There is a accommodating groove at the junction, and a guide groove is provided on the other surface of the guide seat opposite to the direction of the groove, and the grinding drill bits are respectively arranged in the accommodating grooves, and the grinding The outer edge of one side of the drill bit penetrates out of the accommodating grooves.

The control panel is located on the side of the drill body with the through grooves, and a plurality of guide rails are respectively connected to the guide grooves on a surface of the control panel, and the guide rails are located near the center of the control panel to The arc curve extends to the periphery of the control panel.

Wherein, the through grooves are equidistantly recessed and looped on a surface of the drill body.

The reaming drill bit structure of the drilling machine provided by this creation is mainly used for drilling and cutting by the grinder provided on the drill body while the main body of the drill bit is driven to perform drilling. When cutting, you don’t need to pull out the drill body. You only need to rotate the control panel so that the guide seat is pushed by the guide rail of the control panel and pushes out along the groove to the periphery of the drill body, so that it is installed in the guide seat. The grinding drill is exposed on the outer edge of the drill body to perform reaming and drilling through the grinding drill. Therefore, compared with the conventional drilling machine, two-stage drilling operations are required. The drilling and cutting action can be carried out by changing the drill bit, thereby increasing the efficiency of drilling and avoiding the collapse of the hole wall when the drill bit is changed.
