Abstract
The utility model relates to a clamping device for processing an inclined hole on the cylindrical surface of a shaft, which is mainly characterized in that: the clamping device consists of two opposite halves, wherein the outer sides of the two halves correspond to and are connected with the clamping end of a chuck jaw; a semi-cylindrical clamping surface is arranged at the inner side of each half of fixtures, the axial line of the semi-cylindrical clamping surface is inclined backwards, and an included angle between the axle line of the semi-cylindrical clamping surface and a chuck plane is equal to that between the axle line of the inclined hole of a workpiece and the radial direction of the workpiece. A groove with a side opening is arranged at the inner side of each half of fixtures, is communicated with the cylindrical surface of the clamping surface and corresponds to a horizontal drill bit arranged on an NC (numerical control) lathe saddle. The clamping device has the following characteristics: the clamping device can realize quick clamping and has high production efficiency; as a special fixture, the clamping device can realize accurate positioning and has high processing precision; moreover, little abrasion of the drill bit is caused and the processing cost is low.
Description
Technical field
The utility model relates to a kind of processing unit (plant) of shaft-like workpiece cylinder inclined hole.
Background technology
At present; inclined hole on the axle class cylinder; generally all want to finish on the work in-process heart or the CNC milling machine; because machining center and CNC milling machine belong to high-end devices and not only cost an arm and a leg; and processing cost height; adopt special fixture to finish 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, be provided with the big inclined hole of diameter greater than the workpiece inclined hole on position corresponding with the workpiece inclined hole on the pressing plate, 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, again workpiece is installed in the anchor clamps and lock by screw then, shake pull bar drill bit is pierced in the workpiece by fairlead.The drawback that this kind processing mode exists is: 1, the positional precision in hole be 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 purpose of this utility model is to provide a kind of clamping quick, and crudy is good, the clamping device of the axle class cylinder inclined hole processing that production efficiency is high.
The utility model is the anchor clamps that are used on the centre numerically controlled lathe, and it is 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 anchor clamps is fixed on the chuck jaw.The opposite side of two halves anchor clamps is that the relative side (inboard) of two halves anchor clamps is established half-cylindrical clamping face, 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.Above-mentioned groove is corresponding with the horizontal drill bit on being located at the numerically controlled lathe knife rest.
During use, workpiece is placed in the clamping face of two halves anchor clamps, control by numerically controlled lathe clamps button and clamps or unclamp, it cooperates with drill bit on being located at the numerically controlled lathe knife rest, set centre drill centering through numerical control programming, actuating motor makes the workpiece rotation on the main shaft drive chuck then, and the drill bit of auto-feed then will get out inclined hole above the workpiece.
The utility model compared with prior art has following advantage:
1, need not feel relieved behind a clamping location, clamping is quick, the production efficiency height again.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, the machining accuracy height.
3, processing cost is low.
Description of drawings:
Fig. 1 is that the master of the utility model user mode looks schematic diagram.
Fig. 2 is the schematic top plan view of the utility model user mode.
Fig. 3 is the schematic side view of the utility model user mode.
The specific embodiment: in the schematic diagram of the clamping device of Fig. 1, Fig. 2 and axle class cylinder inclined hole shown in Figure 3 processing, 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 anchor clamps is fixed on the chuck jaw.Half-cylindrical clamping face is 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.Above-mentioned groove is corresponding with the horizontal drill bit 6 on being located at the numerically controlled lathe knife rest.
