Abstract

The utility model relates to the technical field of internal combustion locomotives, and in particular relates to a three-point-fixed rapid clamping drilling jig. The drilling jig comprises a die body, a handle, a swivel nut, a shaft sleeve, a hanging rod, a wedge, an ejector pin and a drilling sleeve, wherein the handle is positioned on the top of the swivel nut; the shaft sleeve and the drilling sleeve are respectively positioned at the center and on the edge of the die body; the hanging rod is inserted into the shaft sleeve, the upper part of the hanging rod is connected with the swivel nut, and the lower part of the hanging rod is connected with the wedge; and the ejector pin is inserted in the side part of the shaft sleeve. The three-point-fixed rapid clamping drilling jig can be used for processing a hole at the middle part of a large product, can be used for clamping conveniently, reduces labor intensity greatly, guarantees product precision, can clamp and be detached rapidly, and is convenient to operate and high in efficiency.

Description

3 fixing quick-clamping drill jigs
Technical field
The utility model relates to the diesel locomotive technical field, especially a kind of 3 fixing quick-clamping drill jigs.
Background technology
The product of large parts; such as gearbox and so on; there are some relatively symmetrical holes of certain position array the middle part; with general drill jig processing; need compress drill jig with long pressing plate during clamping; pressing plate needs the very long thrust that causes little, and drill jig can rotate when boring, can not satisfy fixedly requirement of bushing plate.Product quality can not guarantee, and operator's labour intensity is large, the inefficiency of processing.
The utility model content
Little in order to overcome existing drill jig clamping force, easily to rotate, precision is low, the deficiency that labour intensity is large, the utility model provides a kind of 3 fixing quick-clamping drill jigs.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of 3 fixing quick-clamping drill jigs, comprise die body, handle, swivel nut, axle sleeve, suspension rod, voussoir, thimble and drill bushing, handle is positioned at the swivel nut top, axle sleeve and drill bushing lay respectively at central authorities and the edge of die body, and suspension rod is inserted in the axle sleeve, and top connects swivel nut, bottom connecting wedge, thimble are inserted in the axle sleeve sidepiece.
According to another embodiment of the present utility model, comprise that further suspension rod is threaded with swivel nut, is rotatably connected with voussoir.
According to another embodiment of the present utility model, comprise that further cover has return spring on the thimble.
According to another embodiment of the present utility model, comprise that further thimble and axle sleeve are slidingly connected.
The beneficial effects of the utility model are, utilize 3 fixedly quick-clamping drill jigs, can process hole, large part product middle part, such as the processing of gearbox macropore both sides, convenient mounting and clamping reduces labour intensity greatly, not only guaranteed Product Precision, quick-clamping, dismounting, easy to operate, efficient is high, the hole processing of the middle part of various large-scale workpieces is all had initiative reference function.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model top view.
1. die bodys among the figure, 2. handle, 3. swivel nut, 4. suspension rod, 5. voussoir, 6. thimble, 7. drill bushing, 8. axle sleeve, 9. return spring.
The specific embodiment
Structural representation of the present utility model such as Fig. 1, Fig. 2 is the utility model top view, a kind of 3 fixing quick-clamping drill jigs comprise die body 1, handle 2, swivel nut 3, axle sleeve 8, suspension rod 4, voussoir 5, thimble 6 and drill bushing 7, handle 2 is positioned at swivel nut 3 tops, axle sleeve 8 and drill bushing 7 lay respectively at central authorities and the edge of die body 1, and suspension rod 4 is inserted in the axle sleeve 8, and top connects swivel nut 3, bottom connecting wedge 5, thimble 6 are inserted in axle sleeve 8 sidepieces.Suspension rod 4 is threaded with swivel nut 3, is rotatably connected with voussoir.Cover has return spring 9 on the thimble 6.Thimble 6 is slidingly connected with axle sleeve 8.
In order to guarantee that drill jig has correct location and clamping at workpiece, improve and bore working (machining) efficiency, quick-clamping compresses and quick-detachment when the clamping drill jig, the convenient use, special 3 fixing quick-clamping drill jigs.
During use, die body 1 locating surface is aimed at converted products hole inwall, to good direction, as long as rotary handle 2 is tightened swivel nut 3, suspension rod 4 just drives voussoir 5 and upwards promotes, under the jammed effect on voussoir 5 inclined-planes, thimble 6 will be forced outwardly elongation, thereby holds out against in the self-locking of holes of products inwall; Three thimbles 6 have held out against the hole inwall on the die body 1, and by suspension rod 4 screw-threaded couplings, fixedly die body 1,3 fixed precision height, and the clamping drill jig is easily and fast, during the dismounting drill jig, as long as reverse rotation handle 2, unclamp swivel nut 3, suspension rod 4 will drive voussoir 5 and land vacating space downwards, thimble 6 is under the effect of return spring 9, inwardly shrink, remove the locking to the holes of products inwall, die body 1 just can be realized quick-detachment.
