Preferably, the inside of the fixing clamp is all provided with cushion, and rubber item is provided between two adjacent groups cushion.

Preferably, the station is cylindrical, and the inside of station is hollow structure, at the top of the station in Between be provided with through-hole at position.

Preferably, fixing clamp described in two adjacent groups is connected by spring, and spring between fixing clamp described in two adjacent groups Number is five groups, and the equidistantly distributed from top to bottom of spring described in five groups.

Preferably, the front of the station is provided with door, and handle is provided on door.

Preferably, column described in four groups is welded on the top of station.

Compared with prior art, the utility model has the beneficial effects that this kind of tool for drilling fixture passes through the four of setting Group fixing clamp can be surrounded by a rectangle clamping part, be combined with multiple groups cylinder again by the spring and rubber item of setting and use, can Fixation is clamped to different size of workpiece, and clamping effect is more preferable, prevents workpiece in boring procedure from loosening, convenient for beating The progress of hole operation, so that drilling effect is more preferable.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-3 is please referred to, a kind of embodiment provided by the utility model: a kind of tool for drilling fixture, including station 1, the four corners at 1 top of station are all equipped with column 4, and the inside of column 4 is all provided with cylinder 9, and the output end of cylinder 9 is all Fixing clamp 3 is installed, the number of fixing clamp 3 is four groups, and four groups of fixing clamps 3 constitute rectangle clamping part 2, two adjacent groups fixing clamp Spring 5 is provided between 3.

The utility model surrounds a rectangle clamping part 2 by four groups of four groups of fixing clamps 3 of setting, passes through the spring of setting 5 and rubber item 6 be combined with 9 use of multiple groups cylinder again and different size of workpiece can be fixed.

It please focus on refering to Fig. 3, the inside of fixing clamp 3 is all provided with cushion 7, and cushion 7 plays the work protected to workpiece With, and rubber item 6 is provided between two adjacent groups cushion 7, the retractility of rubber item 6 makes cylinder 9 can be to rectangle clamping part 2 Size is adjusted.

Please emphatically refering to fig. 1 and Fig. 2, station 1 is cylindrical, and the inside of station 1 is hollow structure, station 1 The middle position at top is provided with through-hole 8, falls into station 1 convenient for the waste material of punching, the front of station 1 is provided with storehouse Door 10, and it is provided with handle on door 10, convenient for being collected to the waste material inside station 1.

Please be emphatically referring to Fig.2, two adjacent groups fixing clamp 3 be connected by spring 5, and spring 5 between two adjacent groups fixing clamp 3 Number be five groups, and five groups of springs 5 equidistantly distributed from top to bottom preferably changes the spacing between fixing clamp 3, to change The size of bending moment shape clamping part 2, four groups of columns 4 are welded on the top of station 1, so that column 4 is more firm, more favorably In the progress of punching.

Working principle: when workpiece is larger, powering on, and under the action of spring 5 and rubber item 6, cylinder 9, which pulls, to be fixed Folder 3 is displaced outwardly, so that the area of rectangle clamping part 2 expands, is then put the workpiece in rectangle clamping part 2, at this point, gas Cylinder 9 pushes out fixing clamp 3, is clamped with this to workpiece, can carry out punch operation to workpiece after being fixedly clamped, It when workpiece is smaller, puts the workpiece in rectangle clamping part 2, then cylinder 9 pushes out fixing clamp 3, is come with this to workpiece It is clamped fixation.

It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new The range of type is indicated by the appended claims rather than the foregoing description, it is intended that containing for the equivalent requirements of the claims will be fallen in All changes in justice and range are embraced therein.It should not treat any reference in the claims as limiting Related claim.
