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

A kind of drilling tool
Technical field
The present invention relates to field of mechanical technique, is a kind of drilling tool specifically.
Background technology
Plane disc type work processes decentralised hole, and generally all adopt on machining center or lathe and complete for twice with frock skew, this processing mode not only efficiency is low, and eccentric throw is unstable, reduces the degree of accuracy of eccentric orfice.
Summary of the invention
For solving the problem, the object of this invention is to provide a kind of drilling tool.
The present invention for achieving the above object, a kind of drilling tool, comprise holder, eccentric drill bushing, pressing plate, T-shaped Lengthened bolt, T-slot, clamping screw, the both sides upper surface of described holder arranges T-slot respectively, vertical T-shaped Lengthened bolt is set in described T-slot respectively, the pressing plate having one piece of level is run through at the T-shaped Lengthened bolt top of both sides respectively, described eccentric drill bushing both sides arrange projection, the clamping screw that projects through of described eccentric drill bushing is separately fixed on the pressing plate of both sides, and the centre bottom described holder is provided with through hole.
Owing to adopting above technical scheme, the invention has the advantages that:
1. versatility is comparatively strong, and the length difference by adjusting two side guides realizes the eccentric boring hole of diverse location, and makes eccentric throw more stable.
2. clamp structure is simple, and convenient manufacture, closes mass production.
3. easy to operate, make the originally complicated operation that clamps become simple.
4. can assist high-precision processing request.
Accompanying drawing explanation
Now the present invention will be further described by reference to the accompanying drawings.
Fig. 1 is structural representation of the present invention.
In figure: 1, holder; 2, eccentric drill bushing; 3, pressing plate; 4, T-shaped Lengthened bolt; 5, T-slot; 6, clamping screw; 7, through hole.
Detailed description of the invention
As shown in Figure 1, a kind of drilling tool, comprise holder 1, eccentric drill bushing 2, pressing plate 3, T-shaped Lengthened bolt 4, T-slot 5, clamping screw 6, the both sides upper surface of holder 1 arranges T-slot 5 respectively, vertical T-shaped Lengthened bolt 4 is set in T-slot 5 respectively, the pressing plate 3 having one piece of level is run through at T-shaped Lengthened bolt 4 top of both sides respectively, eccentric drill bushing 2 both sides arrange projection, the clamping screw 6 that projects through of eccentric drill bushing 2 is separately fixed on the pressing plate 3 of both sides, and the centre bottom holder 1 is provided with through hole 7.
The foregoing is only the schematic detailed description of the invention of the present invention, and be not used to limit scope of the present invention.Any those skilled in the art, equivalent variations done under the prerequisite not departing from design of the present invention and principle and amendment, all should belong to the scope of protection of the invention.

Claims (1)
