Description

A kind of indexing slotting attachment
Technical field
The utility model is related to technical fields of mechanical processing, and in particular to a kind of slotting attachment.
Background technology
Existing milling method is that workpiece is fixed on machine tool accessories universal dividing head by reserved technique collet On.When processing, any two lateral aperture is selected to load onto pin, beats the level that table corrects two pins;After processing a slot, unclamps and divide The retaining mechanism for spending head, 90 ° are rotated clockwise by handle, tighten retaining mechanism, complete primary indexing, carry out adding for next slot Work.The milling of four bar grooves on workpiece is completed through indexing three times.
In Milling Process, different directions slot on workpiece circumference facilitates not as good as on flat work pieces, moreover workpiece itself Shape is irregular.Several factors are considered before processing, be orientation problem first, for workpiece without being properly positioned, processing every time must weight It is new to play table correction;Followed by clamping problems, since workpiece is used as former material using polytetrafluoroethylene (PTFE) (SFB-2QB/T3626-1999) Material, material stiffness is poor, and clamping force is unable to control, it may appear that workpiece is not clamping to fly out or tension causes workpiece deformation big, and damages The phenomenon that;In addition to the increased technique collet convenient for the clamping on dividing head, makes spillage of material increase;Also increased work Skill collet must increase process flow removal etc. so that the entire process-cycle is longer, and processing efficiency reduces, and manufacturing cost improves; Can not reliably it ensure in the processing quality and adaptation of workpiece, small lot process requirements.
Utility model content
The utility model aim is to overcome disadvantages mentioned above and one kind for providing is simple in structure, small, light-weight, operation Convenient indexing slotting attachment.
A kind of indexing slotting attachment, is made of, positioning device is with circular hole and end face positioning device, clamping device, clamp body It for positioning datum, is positioned with two fixed positioning pins are setting element, positioning pin excessively coordinates with clamp body, and clamp body connects Each element of welding fixture;Clamping device uses helical pressure clamp system, is made of studs, pressing plate, nut, screw, double end Stud is threadedly secured on clamp body, and is equipped with screw respectively, and pressing plate is sleeved on studs, tightening nut, by pressing plate Compacting processing workpiece.
The positioning device is made of setting element and clamp body.
The positioning pin is vertically fixed on clamp body.
The pressing plate uses opening pattern.
Hole on the pressing plate is open hole.
Described clamp body one end is the structure type of square, and the other end is designed to the related position that machine tool accessories connects Cylinder.
The utility model has the beneficial effects that:
Positioning device is to prevent workpiece fixed to determine position of the workpiece in fixture, clamping device in the utility model Occupied position generates displacement due to by the outer force effect such as gravity, inertia force in process when position, while preventing or subtracting Few vibration.The machining accuracy for the guarantee workpiece that this fixture can be stablized improves the labor productivity of mechanical processing and reduces workpiece Manufacturing cost, simple in structure, manufacturing cost is low.Easy to operate, laborsaving, safety, chip removal is convenient, has good structural manufacturing process Property, it is convenient for manufacture, assembly, inspection, adjustment and the repair of fixture.
Description of the drawings
Fig. 1 is the utility model front view;
Fig. 2 is the sectional view of the A-A of Fig. 1;
In figure:1- clamp bodies, 2- positioning pins, 3- studs, 4- workpiece, 5- pressing plates, 6- nuts.
Specific implementation mode
The technical solution of the utility model is described further below in conjunction with attached drawing, but required protection domain is not It is confined to described;
As shown, indexing slotting attachment provided by the utility model, by positioning device, clamping device, 1 group of clamp body At.Positioning device is positioned using circular hole and end face as positioning datum, with two fixed positioning pins 2 for setting element, positioning pin 2 Excessively coordinate with clamp body 1, each element of 1 jockey of clamp body;Clamping device uses helical pressure clamp system, by double end spiral shell Column 3, pressing plate 5, nut 6, screw composition, studs 3 is threadedly secured on clamp body 1, and is equipped with screw respectively, pressing plate 5 are sleeved on studs 3, tightening nut 6, by 5 compacting processing workpiece 4 of pressing plate.
The positioning device is made of setting element and clamp body 1.
The positioning pin 2 is vertically fixed on clamp body 1.
The pressing plate 5 uses opening pattern.
Hole on the pressing plate 5 is open hole.
1 one end of the clamp body is the structure type of square, and the other end is designed with the related position that machine tool accessories connects At cylinder.
The application method of the utility model is:
Cylinder one end of clamp body 1 machine tool accessories universal dividing head collet is clamped, the rectangle of table holder for correcting specific 1 is beaten End face is allowed to parallel with lathe table top;Workpiece 4 is installed, is positioned on clamp body 1 with the holes φ 2H7 2- and end face, covers pressing plate 5, Tightening nut 6 can be such that workpiece 4 is clamped with clamp body 1.After processing a slot, the retaining mechanism of dividing head is unclamped, by handle 90 ° are rotated clockwise, retaining mechanism is tightened, primary indexing is completed, carries out the processing of next slot.Work is completed through indexing three times The milling of four bar grooves on part 4.Workpiece 4 processes, and unscrews nut 6, and side can be taken off workpiece 4 after removing pressing plate 5.Next work When part is processed, it is not necessary to which holder for correcting is specific again, is mounted directly.
The nouns of locality such as left and right, upper and lower, forward and backward involved in the utility model are used only for other people reasons to technical solution Solution, be not used to limit the scope of protection of the utility model, all deformations made on the basis of the technical solution of the utility model, Modification or equivalent replacement etc., should all fall into the scope of protection of the utility model.
