Description
Technical Field
The utility model belongs to the technical field of twist drills, and particularly relates to an integrally-formed high-stability twist drill.
Background
Twist drills are tools for drilling round holes in workpieces by rotating the twist drill relative to a fixed axis, are so called because the chip flutes are formed in a spiral shape, and can be used by being held by a hand-held drilling tool, a drilling machine, a milling machine, a lathe, or a machining center, which is driven by a hand or an electric motor, and are generally used for drilling a workpiece.
When the existing twist drill is installed on a drilling tool for use, the existing twist drill is easy to slip in the high-speed rotating process and is not stable enough due to the simple installation structure.
SUMMERY OF THE UTILITY MODEL
The utility model mainly aims to provide an integrally-formed high-stability twist drill which is used for improving the stability of the twist drill in the using process.
In order to achieve the above object, the present invention provides an integrally formed high stable twist drill, which comprises a twist drill screw bit and a twist drill rod; the spiral drill bit of the twist drill is connected with the first end of the drill rod of the twist drill; the second end of the twist drill rod is hollowed inwards to form an inner cavity; the inner cavity of the twist drill rod is internally provided with a clamping column, and the clamping column is provided with first clamping stripes.
According to the scheme provided by the utility model, the drill rod of the twist drill is inserted into the drilling tool, and the internal structure of the drilling tool is clamped on the clamping column through the first clamping stripe, so that the possibility of slipping of the twist drill in use is reduced, and the stability of the twist drill in use is improved.
In a possible implementation manner, the inner wall of the inner cavity of the twist drill rod is provided with second clamping stripes. The drilling tool inner structure one side block is on the first block stripe of block post, and the opposite side block is on the second block stripe on the inner wall, and stability when further having improved the fluted drill use.
In a possible implementation manner, eight first engaging stripes are uniformly arranged along the outer wall of the engaging column.
Further, in a possible implementation manner, eight second engaging stripes are provided, and the arrangement position of the second engaging stripe corresponds to the arrangement position of the first engaging stripe.
In a possible implementation manner, the twist drill rod is provided with an oil dripping hole, and the oil dripping hole is communicated to an inner cavity of the twist drill rod. After the twist drill is installed on the drilling tool, the oil dripping hole can not extend into the drilling tool, but is exposed outside, so that lubricating oil can be dripped into the inner cavity of the twist drill through the oil dripping hole.
In one possible implementation, the twist drill auger and the twist drill stem are integrally formed. The twist drill has the advantages that the twist drill screw drill and the twist drill rod are integrally formed, so that the structural strength of the twist drill is higher and more stable.

fig. 2 is a view of a second end of a twist drill stem provided by the present invention.
Detailed Description
The following description is presented to disclose the utility model so as to enable any person skilled in the art to practice the utility model. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The basic principles of the utility model, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the utility model.
In the description of the present application, it is to be understood that the terms "upper", "lower", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present application.
In the description of the present application, the terms "first", "second", and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated.
Referring to fig. 1 and 2 of the drawings, the integrally-formed high-stability twist drill provided by the utility model comprises a twist drill screw bit 1 and a twist drill rod 2; the spiral drill bit 1 of the twist drill is connected to the first end of the drill rod 2 of the twist drill; the second end of the twist drill rod 2 is hollowed inwards to form an inner cavity 3; an engaging column 4 is arranged in the inner cavity 3 of the twist drill rod 2, and a first engaging stripe 51 is arranged on the engaging column 4.
According to the scheme provided by the utility model, the drill rod of the twist drill is inserted into the drilling tool, and the internal structure of the drilling tool is clamped on the clamping column 4 through the first clamping stripe 51, so that the possibility of slipping of the twist drill in use is reduced, and the stability of the twist drill in use is improved.
In a possible implementation, the inner wall of the inner cavity 3 of the twist drill rod 2 is provided with second engaging striations 52. One side of the internal structure of the drilling tool is clamped on the first clamping stripe 51 of the clamping column 4, and the other side is clamped on the second clamping stripe 52 on the inner wall, so that the stability of the twist drill in use is further improved.
In a possible implementation manner, eight first engaging stripes 51 are uniformly arranged along the outer wall of the engaging column 4.
Further, in a possible implementation manner, eight second engaging stripes 52 are provided, and the arrangement position of the second engaging stripe 52 corresponds to the arrangement position of the first engaging stripe 51.
In a possible implementation manner, the twist drill rod 2 is provided with an oil drip hole 6, and the oil drip hole 6 is communicated to the inner cavity 3 of the twist drill rod 2. After the twist drill is installed on the drilling tool, the oil dripping hole 6 cannot stretch into the drilling tool and is exposed outside, so that lubricating oil can be dripped into the inner cavity 3 of the twist drill through the oil dripping hole 6.
In one possible implementation, the twist drill auger bit 1 and the twist drill stem 2 are integrally formed. The twist drill has the advantages that the twist drill is higher and more stable in structural strength due to the fact that the twist drill screw bit 1 and the twist drill rod 2 are integrally formed.
It should be noted that the technical features of the drilling tool and the like related to the present patent application should be regarded as the prior art, and the specific structure, the operation principle, the control mode and the spatial arrangement mode of the technical features may be selected conventionally in the field, and should not be regarded as the utility model of the present patent, and the present patent is not further specifically described in detail.
