Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, non-processing plane boring chamfering device for Digit Control Machine Tool of the present utility model, comprises fairlead 1, chamfering device body 4, adjusts screw 2, locating part 6, drill bit 8, drill bit lock-screw 7 and positioning component.Described chamfering device body 4 is arranged in the step through-hole of described fairlead 1, and the axis part of described chamfering device body 4 arranges step through-hole.Described adjustment screw 2 is arranged on by screw thread in the through hole of described fairlead 1, the length of stretching out for adjusting described drill bit 8.Described locating part 6 touches with drill bit 8, and is arranged on the lower end of described adjustment screw 2.Described drill bit lock-screw 7 is connected with drill bit 8 through the radial direction through hole of chamfering device body side setting in 4 weeks, for the clamping and positioning of drill bit 8.Described positioning component is arranged on the bottom of described chamfering device body 4, this positioning component comprises positioning sleeve 12 and back-up ring assembly, described positioning sleeve 12 can rotate freely with respect to described chamfering device body 4, like this positioning sleeve 12 lower surfaces can be limited to exhaust manifold treat boring, chamfering non-processing end face on, be convenient to the drilling depth location of drill bit 8, can avoid again producing and rubbing between positioning sleeve 12 and non-processing end face.Described back-up ring assembly comprises inner shield ring 11 and outer back-up ring 10, inner shield ring 11 and outer back-up ring 10 are installed on respectively in the cannelure arranging on described chamfering device body 4 and positioning sleeve 12, and between positioning sleeve 12 and described chamfering device body 4, single direction thrust ball bearing 14 and deep groove ball bearing 13 are set, be convenient to positioning sleeve 12 with respect to the rotation of chamfering device body 4.Described positioning sleeve 12 tops can arrange dust cap 9, to prevent that dust from falling into single direction thrust ball bearing 14 and deep groove ball bearing 13.On described adjustment screw 2, Compress Spring 3 is set, for the elastic compression of chamfering device body 4.6 weeks sides of described locating part arrange guide pin 5, for the slide-and-guide of locating part 6, and the gathering sill 15 that the side setting in 6 weeks of described locating part and described guide pin 5 are slidably matched.
Operation principle: chamfering device of the present utility model in use, packs the chamfering device of utility model into Digit Control Machine Tool handle of a knife by Digit Control Machine Tool transmitting torque.First confirm a collection ofly will to hole, the excursion of the non-processing end face of chamfering, to hole, non-processing end face distance fixture (platen) the height change difference of chamfering; Then tool setting, makes crown height (qualified chamfering) in chamfering device be less than or equal to the minimum constructive height of non-processing end face; According to workpiece, require to finish procedure.Digit Control Machine Tool according to program hole, during chamfer machining, chamfering device approaches non-processing end face under the drive of main shaft, when the positioning sleeve of chamfering device and described non-processing end contact, chamfering device body no longer moves down, and by bit, can complete chamfering; If described non-processing end face exceeds while setting minimum of a value, due to the positioning sleeve of chamfering device with described non-processing end contact, chamfering device body no longer moves down and continues processing, has guaranteed this batch of uniformity that workpiece is processed; Now machine tool chief axis parameter Z value is not covered, it can continue descending, until parameter Z value is covered, in this process, under workpiece (fixing) and machine tool chief axis (moving down) effect, overcome the elastic force of described Compress Spring in chamfering device, force chamfering device body to drive drill bit and positioning component to move up along fairlead, until cover the Z value rest parameter value after positioning sleeve and described non-processing end contact, guaranteed the uniformity of this batch of workpiece screwed hole oral area chamfering angle size.If the non-processing end face of workpiece blank exceeds while setting minimum of a value, without chamfering device, but directly load onto chamfering tool, the product processing there will be processing excessively dark, causes product rejection; If the non-processing end face of workpiece blank is when setting minimum of a value, chamfer machining is not in place or there is no chamfering, causes product defective.So supporting Digit Control Machine Tool of chamfering device of the present utility model, can complete blank orifice chamfer, counterbore, the boring of different product different pore size, guarantee that chamfering, hole depth are in the same size, realize automatic tool changer, be specially adapted to batch production processing, there is stronger extensive versatility.
