Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 1, Fig. 2 and Fig. 3, upper as can be seen from figure, the utility model bit tool position adjusting mechanism, comprise the cylinder shell 1 of both ends open, be fixed with in housing 1 one end and install cutting ferrule 2, in housing 1, be provided with driving gear 3, driving gear 3 center has a protuberance 4, protuberance 4 is nested in cutting ferrule 2 rotationally, protuberance 4 end face be provided with for line shaft clamping with the clamping square hole 5 with line shaft synchronous axial system.Cutting ferrule 2 is provided with the clip 6 for being held tightly by line shaft, and clip 6 is provided with lock-screw 7.Some driven gears 8 be engaged with are provided with around driving gear 3, each driven gear 8 is fixedly connected with cutter shaft 9, cutter shaft 9 to stretch out and by bearings, be provided with cutter chuck 10 at cutter shaft 9 external part, namely cutter is fixedly mounted on cutter chuck from the housing other end.
During installation, line shaft to be stretched in cutting ferrule and with the clamping of clamping square hole to realize synchronous axial system, is locked after line shaft clamping puts in place by clip and lock-screw again.When line shaft rotates time, because it is connected by clamping square hole with protuberance, therefore with protuberance driving gear synchronous axial system thereupon integrally, driving gear drives driven gear to rotate again, driven gear drives corresponding cutter shaft to rotate, thus all cutters are rotated, realize the effect that much knives tool is synchronously holed.In this much knives tool, if certain tool position does not need machining hole, only need this cutter to take off.
Position between the hole processed due to different workpieces and hole and spacing difference, in order to adapt to this needs, the utility model is made to have certain versatility, the utility model to have carried out improving that make it can adjusting position to cutter shaft structure, concrete structure is described below: each driven gear 8 is connected with cutter shaft 9 by driven shaft 11, driven shaft 11 two ends are connected with driven gear 8 and cutter shaft 9 respectively by two parallel rotating shafts, rotating shaft makes driven shaft be connected with driven gear afterwards and driven shaft is connected rear rotatable with cutter shaft, and rotation direction is carried out in diametric(al).Be installed with the adjustment seat 12 of ring-type at housing 1 cutter shaft end, adjustment seat 12 is provided with the adjustment screw 13 consistent with driven gear quantity.Each cutter shaft 9 is respectively provided with a regulating block 14, and bearing is located on regulating block.Regulating block 14 is provided with regulating tank 15, and the adjustment screw 13 in adjustment seat is stretched out and is locked by nut 16 in the regulating tank 15 of correspondence.When needing to regulate, unclamp nut 16, make cutter be adjusted to the position of needs by regulating block 14, and then be locked by nut 16, because driven shaft two ends are connected with driven gear and cutter shaft respectively by rotating shaft, therefore rotary motion can be delivered on cutter by driven shaft.By the design of adjustment seat and regulating block, the hole of processing can be made to be positioned at different-diameter circumferentially, more to correspond to actual needs, use more flexible.And this cutter head also can be adjusted to separately in the distance different from casing center by each cutter, and adaptability is stronger.
Described adjustment seat 12 is provided with the auxiliary stopper pin 17 corresponding with regulating block, and auxiliary stopper pin 17 is positioned on diameter of the housing direction with corresponding adjustment screw 13 line.Coordinated with adjustment screw 13 by auxiliary stopper pin 17, can guarantee that regulating block can only regulate in diametric(al), thus improve the accuracy regulated.
Some stiffeners 18 are provided with between described adjustment seat 12 and housing 1 outer wall.Owing to housing existing the many groups of cutters worked simultaneously, higher to the requirement of strength of housing, make the intensity of housing be guaranteed thus by setting up stiffener.
Described regulating block is provided with adjustment scale along the direction of regulating tank.Because most cases lower opening circumferentially angularly distributes, namely tool position is identical, therefore can be regulated easily by scale.Also can by scale make each cutter shaft be adjusted to identical circumferentially or other position needed.
During actual design, described driven gear is eight covers angularly distributed, and corresponding driven shaft, cutter shaft and regulating block are also eight covers.The needs of majority of case can be met like this.If wherein four cover cutters need not, so can process equal angular 8 holes or 4 holes on this structure simultaneously.
The utility model is often adjustable relative to the distance of casing center cutter, can adapt to different processing requests, both can be positioned at circumferentially same in all holes, and also can be positioned at circumferentially different.Achieve cutter head to be connected with the fast and reliable of line shaft simultaneously, be convenient for changing cutter simultaneously, the function utilizing simple structure to reach porous simultaneously to process, uses convenient, more can enhance productivity.
By arranging scale and auxiliary stopper pin etc., make the adjustment of tool position more convenient and put in place.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
