Abstract

The utility model discloses a swallow tail head lobe piece centre bore boring grab, including the base of mountable on the drilling machine, its characterized in that, the positioning seat is installed to one side of base, installs clamp plate and locating pin on the positioning seat, offer on the positioning seat with the unanimous dovetail of swallow tail capitiform form, it is tight that this dovetail and clamp plate carry out the locating clip to the forked tail tenon jointly, L type supporting seat is installed to the opposite side of base, installs drill bushing and holding screw on the L type supporting seat. The utility model discloses be different from conventional drilling design, these anchor clamps utilize forked tail tenon bottom surface to support, a dovetail location, and the another side adopts the clamp plate to compress tightly along the tenon plane, coordinates positioning pin to the location simultaneously, guarantees that the Z axle of tenon blade is perpendicular and central through anchor clamps with the anchor clamps base, finally limits the degrees of freedom of forked tail tenon, fixes a position more accurately, and the clamping is simple and convenient, practices thrift manufacturing cost, simple structure greatly, need not the alignment, just can process on ordinary radial drill.

Description

Dovetail rabbet working blade center hole boring grab

Technical field

The utility model relates to a kind of boring grab, particularly relates to a kind of dovetail rabbet working blade center hole boring grab.

Background technology

Dovetail rabbet working blade is a crucial blade part on compressor, and due to its complex structure, required precision is high, and the centre bore on it is all generally adopt Five-axis NC Machining Center processing, and processing cost is high, is not suitable for mass large-scale production.

Utility model content

The purpose of this utility model is, develops a kind of structure simple, can be applicable to general general drilling machine, as the dovetail rabbet working blade center hole boring grab of radial drill, not only can simplify operative, also significantly can reduce production cost.

The utility model is achieved by the following technical solution: dovetail rabbet working blade center hole boring grab, comprise the base that can be installed on drilling machine, it is characterized in that, the side of base is provided with positioning seat, positioning seat is provided with pressing plate and alignment pin, positioning seat offers the dovetail groove consistent with dovetail rabbet working shape, this dovetail groove and pressing plate position clamping to dovetail rabbet working jointly; The opposite side of base is provided with L-type supporting seat, L-type supporting seat is provided with drill bushing and holding screw.

Further, described pressing plate is installed on positioning seat by band shoulder nut and stud.

Further, also alignment pin is provided with between supporting seat and base.

Further, described holding screw quantity is 2.

The utility model is different from conventional drilling design, this fixture utilizes dovetail rabbet working bottom supporting, a dovetail groove location, another side adopts pressing plate to compress along tenon plane, coordinate alignment pin axial location simultaneously, ensure that the Z axis of tenon blade is vertical with clamp base and through clamp central, finally limit the spatial degrees of freedom of dovetail rabbet working, location is more accurate, and clamping is more simple and convenient.

Compared with prior art, the utility model has the advantage of:

1, location is more accurate, and this fixture utilizes dovetail rabbet working to locate, and meets blade assernbling mode, makes location more accurate.

2, installation way flexibly, simply, and this device adopts pressing plate along tenon direction compressing component, simple to operate, reliable.

3, greatly save production cost, blade processing time and part processing precision.Structure is simple, plain radial drilling machine just can be processed, and without centering, can ensure machining accuracy again.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation;

Fig. 2 is the side view of Fig. 1.

Detailed description of the invention

Below in conjunction with the drawings and the specific embodiments, the present invention will be further described.

In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.

As shown in Fig. 1 ~ Fig. 2, dovetail rabbet working blade center hole boring grab, comprise the base 1 that can be installed on drilling machine, the side of base 1 is provided with positioning seat 2, positioning seat 2 is provided with pressing plate 11 and alignment pin 12, positioning seat 2 offers the dovetail groove 8 consistent with dovetail rabbet working shape, this dovetail groove 8 and pressing plate 11 form three of dovetail groove, jointly position clamping to dovetail rabbet working; The opposite side of base 1 is provided with L-type supporting seat 4, L-type supporting seat 4 is provided with drill bushing 5 and holding screw 6.

In the present embodiment, positioning seat 2 and supporting seat 4 are all bolted at base 1.

In the present embodiment, pressing plate 11 is installed on positioning seat 2 by band shoulder nut 9 and stud 10.

In the present embodiment, alignment pin 3 is also provided with between supporting seat 4 and base 1.

During utility model works, first unclamp the band shoulder nut 9 on positioning seat 2, pressing plate 11 is made to be in mobilizable state, treat that the dovetail rabbet working of dovetail rabbet working blade 7 is put in dovetail groove 8, adjustment belt shoulder nut 9, pressing plate 11 is made to compress dovetail rabbet working blade 7, when the centre bore on dovetail rabbet working blade 7 top aligns drill bushing 5 center line, adjust 2 holding screws 6, make it be in drillable location status, adjust and can start boring, it should be noted that, can fix after position adjusted by 2 holding screws 6, without the need to adjusting again during boring next time.

The utility model, through field practice, can process up-to-standard part well, meet need of production, simplify the operation of workman simultaneously.

Above is embodiment description is to explanation of the present utility model, not to restriction of the present utility model, the utility model limited range is see claim, and when without prejudice to the utility model basic conception, the utility model can do the amendment of other form.
