Description
Technical field
The utility model belongs to the centring means technical field in drilled hole.
Background technology
In the mechanical processing process of shaft-like workpiece, generally will in advance axle two ends drill centers as processing benchmark, existing drill center hole generally needs to adopt special drill center lathe, this drill center lathe adopts three-jaw self-centering chuck to position shaft-like workpiece, bevel pinion square hole spanner being inserted scroll chuck rotates bevel pinion, bevel gear wheel is driven to rotate by bevel pinion, now claw moves in auger tooth end-face helical, thus clamp and loosen workpiece, the shortcoming of this Set and Positioning mode is: clamping force is less, when drill bit is to shaft-like workpiece end face drill centers, there is the situation of axle back skating possibly, in addition, the clamping time is longer, uses during spanner adjustment clamping force and can expend time in, and loads and dismounting also can the at substantial time, and the batch not being suitable for shaft-like workpiece turns hole machined.
Utility model content
The utility model is intended to provide that a kind of chucking power is strong, the clamping time is short, is applicable to the frock that axial workpiece batch bores center.
Technical scheme in this programme is: the beneficial effect of this programme is: quick drill centre bore frock, comprise base, base is divided into base plate and riser, riser has vertical height-regulating slot, be provided with locating shaft moving up and down in this height-regulating slot, this locating shaft and height-regulating slot are locked by locking nut; Riser is provided with coaxial and that shape is identical upper vee-block, middle vee-block and lower vee-block, height-regulating slot between the V angle of all vee-blocks, and middle vee-block is hinged with coordinates with its V angle the pressing plate forming piece-holder portion.
The beneficial effects of the utility model are: by rational height regulating tank and locating shaft on riser, can realize carrying out end face location to shaft-like workpiece, ensure that shaft-like workpiece can not move axially when carrying out drill centers, avoid the situation causing axial workpiece to slide not because of chucking power as traditional triangle chuck, and can for the axial workpiece adjustment locating shaft of different length, the scope of application is wider; Middle vee-block and pressing plate coordinate can clamp axial workpiece, and pressing plate and middle vee-block hinged, can realize the Quick-clamped of axial workpiece by pulling pressing plate and unclamp, comparing triangle chuck chucking power larger, and shorten the clamping time of axial workpiece, be applicable to axial workpiece batch brill center.
Further, described pressing plate free end is provided with handle, is convenient to pull pressing plate.
Further, it is hinged that described pressing plate and middle vee-block pass through screw, pressing plate has arc notch, can change different pressing plates according to different axial workpieces, improves clamping effect.
Further, described middle vee-block is provided with the snap ring of fixed handle, and workman can manual fixation clip.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model quick drill centre bore frock.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description 1 comprises: 1-base plate; 2-riser; The upper vee-block of 3-; Vee-block in 4-; Vee-block under 5-; 6-locating shaft; 7-screw; 8-pressing plate; 9-arc notch; 10-handle; 11-shaft-like workpiece.
See Fig. 1, quick drill centre bore frock, comprises base, base is divided into orthogonal base plate 1 and riser 2, the bottom of base plate 1 has to fix and is slidably engaged in keyway on drilling machine, when base plate 1 slides into drilling machine correct position, is namely fixed by the bolt on base plate 1 and drilling machine.
The vertical plane of riser 2 is milled with positioning spline, middle positioning spline and lower positioning spline, the upper vee-block 3 that shape is identical, middle vee-block 4 and lower vee-block 5 to be installed on respectively in corresponding positioning spline and to be fixedly connected with riser 2 screw thread.Riser 2 between upper vee-block 3 and lower vee-block 5 is milled with groove, namely this groove is the height-regulating slot between the V angle of all vee-blocks, be fixed with the locating shaft 6 of level in height-regulating slot by locking nut, unclamp locking nut, i.e. the height of adjustable locating shaft 6.
One end of middle vee-block 4 is hinged with pressing plate 8 by screw 7, pressing plate 8 can rotate around this screw 7, with arc notch 9 on this pressing plate 8, this arc notch 9 coordinates the piece-holder portion that can form fixing shaft-like workpiece 11 with the V angle of middle vee-block 4, pressing plate 8 free end is welded with handle 10, pull handle 10, pressing plate 8 can clamp and unclamp shaft-like workpiece 11.Be welded with snap ring at middle vee-block 4 away from one end of screw 7, this snap ring can be enclosed within handle 10 and prevent handle 10 from rotating.
During use, between V angle shaft-like workpiece 11 being put into three vee-blocks of this quick drill centre bore frock, the lower end of shaft-like workpiece 11 is put on locating shaft 6, the height of adjustment locating shaft 6 makes the upper end of shaft-like workpiece 11 extend out to suitable height, pull handle 10 again pressing plate 8 to be coordinated with middle vee-block 4 clamp this shaft-like workpiece 11, be locked by snap ring handle 10, complete the clamping of shaft-like workpiece 11, the drill bit on drilling machine can carry out drill centers to this shaft-like workpiece 11 upper surface.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
