Problems solved by technology

[0002] Machining non-center holes on flat disk workpieces is generally completed by machining centers or lathes with tooling offset twice. This processing method is not only inefficient, but also the eccentricity is unstable, which reduces the accuracy of eccentric holes.

Embodiment Construction

[0013] Such as figure 1 As shown, a drilling tooling includes a fixed seat 1, an eccentric drill sleeve 2, a pressure plate 3, a T-shaped extension bolt 4, a T-shaped slot 5, and a locking bolt 6. The upper surfaces of both sides of the fixed seat 1 are respectively provided with T-shaped Vertical T-shaped extension bolts 4 are arranged in the groove 5 and T-shaped groove 5, and a horizontal pressure plate 3 runs through the top of the T-shaped extension bolts 4 on both sides. The protrusions of 2 are respectively fixed on the pressure plates 3 on both sides by locking bolts 6, and a through hole 7 is arranged in the middle of the bottom of the fixing seat 1.

[0014] The above descriptions are only illustrative specific implementations of the present invention, and are not intended to limit the scope of the present invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principle of the present invention...

Abstract

The invention discloses a drilling tool. The drilling tool comprises a fixed base, an eccentric drill bush, pressing plates, T-shaped lengthened bolts, T-shaped grooves and locking bolts, wherein the T-shaped grooves are formed in the upper surfaces of the two sides of the fixed base respectively, the vertical T-shaped lengthened bolts are arranged in the T-shaped grooves respectively, and the two horizontal pressing plates penetrate through the top portions of the T-shaped lengthened bolts on two sides respectively; protrusions are arranged on the two sides of the eccentric drill bush and are fixed to the pressing plates on two sides through the locking bolts respectively, and a through hole is formed in the middle of the bottom of the fixed base. The drilling tool is high in universality, eccentric drilling in different positions can be achieved by adjusting the lengths of the pressing plates on two sides, and eccentric distance is made more stable.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a drilling tool. Background technique [0002] Machining non-center holes on flat disk workpieces is generally completed by machining centers or lathes with tooling offset twice. This processing method is not only inefficient, but also the eccentricity is unstable, which reduces the accuracy of eccentric holes. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a drilling tool. [0004] In order to achieve the above object, the present invention provides a drilling tool, which includes a fixed seat, an eccentric drill sleeve, a pressure plate, a T-shaped extension bolt, a T-shaped slot, and a locking bolt. T-shaped grooves are respectively arranged on the upper surfaces of both sides of the fixed seat , vertical T-shaped extension bolts are arranged in the T-shaped grooves, and a horizontal pressure ...
