Description
Technical field:
The present invention relates to a kind of digital control processing instrument, particularly a kind of accurately anchor clamps easily of digital control processing special use.
Background technology:
High speed development along with computer technology, the change of essence has taken place in traditional manufacturing industry, utilize Digit Control Machine Tool processing, the quality conformance of its product processing is good, machining accuracy and efficient all exceed much than machine tool, especially add man-hour at the plant product of compoundization processing and high-precision requirement of irregular, the complicated curve of profile or curved surface, multiplex (MUX), its advantage is that traditional machine tool is incomparable.
Anchor clamps are important component parts of numerical control machining center, its effect is that workpiece is fixed on the accurate position of lathe, finish various processing to workpiece, should accurate positioning reliable clamping again, obviously the quality of its structure has fundamental influence to machining accuracy, working (machining) efficiency; The special fixture that digital control processing is used in data be difficult on the net find, generally all is that workpiece is placed on the parallel jaw seldom, with dial gauge centering position, auxiliaryly again locatees with a little parallels, angle bar, clamps with parallel jaw then.Add and also will measure and be provided with workpiece coordinate system man-hour, inefficiency, and positioning accuracy is not high.And clamping can only an orientation of processing work machined surface.
Summary of the invention:
The present invention is directed to the existing problem of the used anchor clamps of above-mentioned existing Digit Control Machine Tool, can locate clamping fast to part, add and need not measure workpiece coordinate system man-hour, and these anchor clamps can change a plurality of orientation, the special fixture of a plurality of machined surfaces of processing work and provide a kind of.
In order to achieve the above object, clamp for numerical control machining involved in the present invention, it mainly comprises a clamp body and several setting elements and clamping device, and described clamp body location is clamped on the T-slot of swinging workbench, and positioning key is fixed on the clamp body bottom and matches with T-slot; Described clamp body top location and installation has a cover plate, and location and installation has a vee-block on the medial surface of clamp body left end; The clamp body rear side is equipped with two location-plates; The edge of clamp body right-hand member is equipped with a vertical fulcrum, and can be around the clamping plate of this fulcrum rotation, and the rotation of described clamping plate is controlled by the clamping device on the clamp body.
Described vertical fulcrum top is having the groove of placing circlip near the inboard of clamp body, a sleeve that fill up clamping plate is placed in the vertical fulcrum bottom, puts a pad that prevents to wear and tear workbench bottom the vertical fulcrum.
Described clamping device is to screw in the clamp body, and can withstand the screw of clamping plate.
Compare with the clamping of parallel jaw centering according to the anchor clamps that technique scheme obtains, can locate clamping fast, positioning accuracy improves a lot.And anchor clamps have definite position on the swinging workbench, and then workpiece coordinate system is also definite fully, and operating efficiency is increased substantially.And clamping can a plurality of orientation of processing work machined surface.

The specific embodiment:
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
In order to solve the existing existing problem of anchor clamps, anchor clamps provided by the invention, its main as Fig. 1 is to shown in Figure 4, and whole system mainly comprises a clamp body and several setting elements and clamping device.Two positioning keys 16 are screwed to match with T-slot in clamp body 1 bottom clamp body are positioned on the workbench, the hexagon-head of bolt 10 passes in T-slot, screw portion passes T type groove on clamp body 1 base plate and puts into packing ring 12 usefulness nuts 11 and tighten, and clamp body is fixed on the T-slot of swinging workbench.
As shown in Figure 1, 2, 3, clamp body 1 top is mounted with a cover plate 3, and at first two pins 4 by the middle part, two ends position, and fix by four screws 5 at four angles again.The location clamps on the medial surface of clamp body 1 left end a vee-block 2, and this vee-block 2 is positioned on the clamp body 1 by two pins 19, fixes (as shown in Figure 3) again with screw 20 then.Clamp body 1 rear side is equipped with two location-plates 18, and location-plate 18 is fixed on (as shown in Figure 1) on the clamp body 1 by three screws 17 respectively.The edge of clamp body right-hand member is equipped with a vertical fulcrum 7, and can be around the clamping plate 6 of this fulcrum rotation, the rotation of this clamping plate 6 is controlled by the screw 9 that screws in the clamp body and can withstand clamping plate 6, make clamping plate 6 have two effects by such device: the one, workpiece is clamped, the 2nd, restriction workpiece Y direction rotary freedom.Vertical fulcrum 7 tops are having groove near the inboard of clamp body 1 so that place circlip 14, prevent that vertical fulcrum 7 from extracting out from top; A sleeve 15 is put so that clamping plate 6 is filled up in vertical fulcrum 7 bottoms, and vertical fulcrum 7 bottoms are put a pad 13 and prevented the workbench that weares and teares.
According to the anchor clamps that technique scheme obtains, can locate clamping splicing sleeve as shown in Figure 5 fast, easily, and because this splicing sleeve one side is the plane, and opposite side is the face of cylinder, parallel jaw is to be difficult to accurate positioning and fixing; These anchor clamps at first by being fixed on two positioning keys that match with T-slot in the clamp body bottom, carry out the accurate location of clamp body in use, with bolt, nut, packing ring anchor clamps are fixed on the workbench then.Vee-block is positioned on the clamp body with two pins, is screwed then.Cover plate is positioned on the clamp body with two pins, then with being screwed.Vertical fulcrum is joined brill in two holes up and down.When fulcrum is installed, put pad earlier, put sleeve then, fulcrum is penetrated sleeve withstand on the pad, then put circlip, cover plate is installed again.
As shown in Figure 6, when sandwiching splicing sleeve, at first splicing sleeve is put in the anchor clamps, the face of cylinder on it is positioned in the vee-block, the plane of splicing sleeve contacts with clamping plate, and the bottom surface is positioned on two location-plates of clamp body, and splicing sleeve contacts with two location-plates by the bottom surface and limited an one-movement-freedom-degree like this, two rotary freedoms, the face of cylinder contact with vee-block and have limited two one-movement-freedom-degrees.Withstand clamping plate with the screw in the screw-in clamp body then clamping plate is rotated around vertical fulcrum, thereby workpiece is clamped, and restriction workpiece Y direction rotary freedom.So just, can accurate localization clamp splicing sleeve, and can carry out required multi-faceted machining it.At first processing
The hole,
Counterbore,
The hole,
Counterbore, 2-M6-6H screw; Then the swinging workbench is revolved and turn 90 degrees processing
The hole.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-mentioned example and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
