Abstract
The utility model discloses a drilling frock, include that fixing base, eccentric drill bushing, clamp plate, T type add stay bolt, T type groove, locking bolt, the both sides upper surface of fixing base sets up T type groove respectively, and T type inslot sets up vertical T type respectively and adds the stay bolt, and the T type of both sides runs through respectively with the stay bolt top has a horizontally clamp plate, and eccentric drill bushing both sides set up the arch, and the arch of eccentric drill bushing is fixed respectively on the clamp plate of both sides through the locking bolt, and the centre of fixing base bottom is provided with the through -hole. The utility model discloses the commonality is stronger, and the length difference of accessible adjustment both sides clamp plate realizes the eccentric drilling of different positions to make eccentricly apart from more stable.
Description
Technical field
The utility model 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.
Utility model content
For solving the problem, the purpose of this utility model is to provide a kind of drilling tool.
The utility model 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 utility model has the advantage of:
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 by reference to the accompanying drawings the utility model is described further.
Fig. 1 is structural representation of the present utility model.
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 utility model, and be not used to limit scope of the present utility model.Any those skilled in the art, equivalent variations done under the prerequisite not departing from design of the present utility model and principle and amendment, all should belong to the scope of the utility model protection.
