Abstract

The invention relates to a method for processing an inclined hole on the cylindrical surface of a numerical control machine tool. The method mainly comprises the following steps: a jig is arranged on the box chuck of the numerical control machine tool, wherein the jig consists of two opposite parts, the outsides of the two parts are connected with the clamping ends of the clamping jaws of the chuck correspondingly; the insides of the two parts of the jig are provided with semi-cylindrical clamping surfaces, the axes of the clamping surfaces incline backward, and the angle between each axis to the plane of the chuck is equal to the angle between the axis of the inclined hole of the workpiece and the radial direction of the workpiece; the insides of the two parts of the jig are provided with grooves with side openings and the grooves are communicated with the cylindrical surfaces of the clamping surfaces; a horizontal bit which can be placed in or out through the grooves is fixed on the tool rest; the workpiece is placed in the clamping surfaces of the two parts, the centering of the centre bit is set through numerical control programming, then the spindle is used to drive the workpiece on the chuck to rotate, and the automatically fed bit is used to drill an inclined hole in the workpiece. The invention has fast clamping process and high production efficiency; the special jig has high processing accuracy and can realize accurate positioning; and the bit has less wear, and the processing cost is low.

Description

Cylinder inclined hole processing method on the Digit Control Machine Tool
Technical field
The present invention relates to a kind of processing method of shaft-like workpiece cylinder inclined hole.
Background technology
At present; Inclined hole on the axle type cylinder is generally all wanted to accomplish on the work in-process heart or the CNC milling machine, not only costs an arm and a leg because machining center and CNC milling machine belong to high-end devices; And processing cost is high; Adopt special fixture to accomplish on the bench drill so can be chosen in usually, these anchor clamps mainly are dimerous by skewback and pressing plate, and the gradient of skewback equals workpiece inclined hole axis and workpiece angle radially.Be provided with coupled pressing plate above the skewback, but establish the axially extending bore of place work piece in the pressing plate, on position corresponding with the workpiece inclined hole on the pressing plate, be provided with the big inclined hole of diameter greater than the workpiece inclined hole, this big inclined hole that is positioned at axially extending bore top is provided with fairlead.On pressing plate, also be provided with another vertical with axially extending bore and be communicated with screw in addition, be provided with lock screw in it.Add man-hour, special fixture is placed on the bench drill work top fixes, workpiece is installed in the anchor clamps lock by screw then again, shake pull bar drill bit is pierced in the workpiece through fairlead.The drawback that this kind processing mode exists is: 1, the positional precision in hole cannot say for sure to demonstrate,prove.The accuracy of alignment of drill bit relies on fairlead fully, because fairlead and drill bit are gapped, so can cause the converted products center deviation to occur.2, fairlead rapid wear changes that frequency is high by 3, drilling tool does not have alignment function and easy to wear, has increased reconditioning frequency 4, fairlead centering causes feed speed low, influences working (machining) efficiency.
Summary of the invention:
The object of the present invention is to provide a kind of clamping quick, crudy is good, the processing method of cylinder inclined hole on the high Digit Control Machine Tool of production efficiency.The present invention mainly is on centre numerically controlled lathe, with anchor clamps workpiece is installed on the spindle chuck, rotate synchronously with main shaft, and drill bit is located on the knife rest, sets centre drill centering, rat holing through numerical control programming.
Particular content of the present invention is following:
1, anchor clamps are installed on the two-jaw(ed)chuck of numerically controlled lathe, these anchor clamps are made up of relative two halves, and their side (i.e. the outside) is corresponding with the chuck jaw bare terminal end, and by securing member with clamps on chuck jaw.The opposite side of two halves anchor clamps is that the relative side (inboard) of two halves anchor clamps is established the half-cylindrical clamping face corresponding with workpiece, and its axis recedes, and equals workpiece inclined hole axis and workpiece angle radially with the angle on chuck plane.Be provided with the side opening groove in the inboard of above-mentioned two halves anchor clamps, this groove is connected with the cylinder of clamping face clamping face is divided into two half-cylindrical clamping faces up and down.On the numerically controlled lathe knife rest, be fixed with the drill bit of level in addition, it can be from above-mentioned groove turnover.
2, workpiece being placed in the clamping face of two halves anchor clamps, is that workpiece is located control through numerically controlled lathe up and down and clamped button and clamp or unclamp by step corresponding with workpiece in the anchor clamps, rotates synchronously with main shaft so that make it.
3, set centre drill centering through numerical control programming, actuating motor makes main shaft drive the workpiece rotation on the chuck then, and the drill bit of auto-feed is then with getting out inclined hole above the workpiece.
The present invention compared with prior art has following advantage:
1, need not feel relieved behind a clamping location, clamping is quick again, and production efficiency is high.The processing that this processing method can make the cylinder inclined hole becomes equally easy with the processing on the turning face of cylinder.
2, special fixture accurate positioning, machining accuracy is high.
3, bit wear is few, and processing cost is low.
Description of drawings:
Fig. 1 is that the master of anchor clamps user mode of the present invention looks sketch map.
Fig. 2 is the schematic top plan view of anchor clamps user mode of the present invention.
Fig. 3 is the schematic side view of anchor clamps user mode of the present invention.
The specific embodiment: on Fig. 1, Fig. 2 and Digit Control Machine Tool shown in Figure 3 in the sketch map of the anchor clamps user mode of cylinder inclined hole processing method; Anchor clamps 1 are installed on two pawls, 2 chucks 3 of numerically controlled lathe; These anchor clamps are made up of relative two halves; Their outside is corresponding with the chuck jaw bare terminal end, and by securing member 4 with clamps on chuck jaw.The half-cylindrical clamping face corresponding with workpiece established in the inboard of two halves anchor clamps, and its axis recedes, and equals workpiece inclined hole axis and workpiece 5 angle radially with the angle on chuck plane.Be provided with the side opening groove in the inboard of above-mentioned two halves anchor clamps in addition, this groove is connected with the cylinder of clamping face clamping face is divided into two half-cylindrical clamping faces up and down.On knife rest, be fixed with the drill bit 6 of level in addition, it can be from above-mentioned groove turnover.Workpiece being placed in the clamping face of two halves anchor clamps, is that workpiece is located up and down by step corresponding with workpiece in the anchor clamps, and the control through numerically controlled lathe clamps button and clamps or unclamp.Set centre drill centering through numerical control programming, actuating motor makes main shaft drive the workpiece rotation on the chuck then, and the drill bit of auto-feed is then with getting out inclined hole above the workpiece.
