Description
Technical field
The present invention relates to the field of drill point milling apparatus, the espespecially a kind of semi open model drill point shank fixture of drill point shank in order to attrition process that grip.
background technology
For precision drilling processing or circuit boring processing, use micro drill point to drill small hole, along with service time one is of a specified duration, the drill bit of this micro drill point and blade also can produce abrasion condition, and affect drilling quality and efficiency, for effectively reducing use cost, these can reclaim again and grind through this micro drill point using, but because the size of this micro drill point is tiny and have high length/diameter ratio, must can again grind by the precise grinding device through particular design, and after being gripped by a stationary fixture, can firmly grind, maintain follow-up its Grinding Quality, stability during for boring, quality or efficiency are closely bound up.
At present, refer to Fig. 1, it is the structural representation of existing stationary fixture, as shown in FIG., this stationary fixture 1 comprises an outer tube 11 and a collar 12 is in the inner set with one heart, this collar 12 has a plurality of intermediate plates 121, between this each intermediate plate 121, be provided with a gap, and the inner face of this each intermediate plate 121 is to shank that should micro drill point 2 and form a cambered surface, the periphery of these intermediate plates 121 described in the internal diameter correspondence of this outer tube 11, therefore, when utilizing this collar 12 outer tube 11 carrying out elevating movement relatively, these intermediate plates 121 described in interlock present the state of opening or closing, and by means of these the described cambered surfaces after these described intermediate plate 121 closures, on average by touching the shank of this micro drill point 2, reach the object gripping.
But, in this stationary fixture practical operation, often run into following point:
1. in the time clamping, the bottom of this micro drill point 2 is connivent in this collar 12 bottoms, so that this precise grinding device 1 is measured length and is ground, but, in the process declining due to this collar 12, this micro drill point 2 can be subject to the strength of lateral compression, causes its position slightly to be risen and causes the error while measuring length, indirectly also can affect the quality while grinding.
Moreover, because this outer tube 11 carries out reciprocal elevating movement with respect to this collar 12, often there is the situation of phase mutual friction therebetween, and likely make this outer tube 11 or this collar 12 produce the phenomenon of wearing and tearing, as abrasion condition becomes the effect that seriously also can have influence on clamping, must just can carry out repair and replacement through the work of disassembling of meticulous portion, thereby significantly promote its maintenance cost.
3. in addition, gap between this outer tube 11 and this collar 12, and gap between this each intermediate plate 121 of this collar 12, all easily there is accumulation dust, must often clear up, as the unsteady problem of clamping seriously likely occurs laying dust problem, also there is the error causing while measuring length.Hereat, be necessary to be improved for the problems referred to above.
