【正文】 M8 hole and 1 14? the holecarries on drills truncates the processing. In the article introducedthe work piece in clamps the concrete center the locate mode, locatesthe part and the detent mechanism choice, and clamps the anizationthe choice and the design. The modern high efficiency jig mostly usesmobile clamps, divides according to the strength source has airoperated, the hydraulic pressure, the gas fluid union, the electricitytransmission and so on carries on using the engine bed movement to thework piece clamps. These ways have clamp the movement quickly, clampsthe strength to be stable, may reduce merit and so on worker laborintensity. This design selects the power unit which the electric motorachievement clamps, the utilization mechanical and electricaltransmission control loop control motor the reverse, is processed inorder to the control the work piece in to clamp concrete on addition, in the article has also carried on the simple precisionanalysis and the putation to the jig. On the machine parts often all has each kind of different use and thedifferent precision hole needs to process. In the machinefinishing,the hole process load accounts for the proportion to be bigger, drillbit, Expanding drilling, Reamer and so on decides the size cutting toolprocessing to occupy quite most. By now, besides had to guarantee thehole the size precision, but also had to achieve the hole the positionprecision request. In the single unit small volume production, afterdraws a line adjusts the hole spool thread position method processing,because the drill bit rigidity bad, is easier to distort, thereforethe production efficiency low also the precision is bad. Generally alluses the drilling machine jig in the volume production, the drillingmachine jig calls 鉆模 , through drills the set of guidance cuttingtool to carry on the processing to be possible accurately to determinebetween the cutting tool and the work piece relative position, is 鉆模 main characteristic. Drills when truncates, is processed thehole the size and the precision mainly by the cutting tool itself sizeand the precision guaranteed。 But the hole position precision bydrills the set to be photogenic in the jig regarding locates the partthe position precision to determine. Because through drills the set ofguidance cutting tool to carry on the processing, this both possiblyenhances the cutting tool system rigidity, and can prevent the drillbit directs.
