When boring the inner hole and the outer circle of the vehicle, the dimensional accuracy of the workpiece is usually obtained by a combination of the trial cutting method and the adjustment method. Since the common cutter body is not adjustable, the human factor is large, and the edge of the machined hole or shaft often digs. The knife phenomenon even makes the workpiece scrapped, which seriously affects the product quality. Moreover, repeated tooling can cause waste of processing assistance time and reduce production efficiency. In addition, because the clamping of the cutter body is directly attached to the cutter body by the Screw, although the screw has a self-locking effect, since it is a point support, the stability is poor, the vibration is easy, and the clamping is not strong enough, and the cutter and the cutter are often appeared. phenomenon. The following describes a set of boring bar that can be used to control the radial feed of the cutter body by fine adjustment of the screw. The wedge force and the screw are used to clamp and clamp the cutter bar to make the cutter. The body clamping reliability is increased, the clamping assistance time is reduced, and the clamping is convenient and quick. After verification, the effect is very good.
The boring bar body is clamped by horizontal and vertical wedge clamping mechanisms, and the wedge is clamped by the inclined surface. The original force of the wedge is obtained by the external force of the screw, because the wedge and the screw are obtained. Both have the effect of locking and boosting, so they have the characteristics of firm clamping, small original force and quick clamping. In addition, a spiral rack is arranged on the cutter body, the rack is fixed on the cutter body by screws, and a fine adjustment screw is arranged on the cutter bar, and the support member of the fine adjustment screw is a front and rear baffle, and can be loosened when the radial feed amount is adjusted. The two clamping screws of the wedge iron are connected with the shaft by the retaining ring. When the screw is loosened, the wedge iron is simultaneously driven to loosen the cutter body, and then the fine adjustment screw is used to adjust the radial feed amount of the cutter body.
In order to make the feed amount readable, the angle tick mark can be marked on the baffle. At the same time, in order to overcome the gap between the screw and the rack pair, avoid fine-tuning the idle stroke. Before loosening the wedge iron, make the fine adjustment screw slightly Preload. In order to ensure the correct engagement of the screw rack sub-mechanism, the gap between the cutter body and the hole should not be too large, and it is recommended to control it in the range of 0.2 to 0.5 mm. At the same time, in the case of a small gap, the clamping stroke of the wedge iron is short, which makes clamping and relaxation faster. In addition, in order to make full use of the tool holder, it is recommended to use an indexable carbide tool.
The working principle of the boring bar for the external turning shaft table is the same as above. Only the wedge clamping is used between the bending bar and the boring bar. There is no fine adjustment mechanism, and the relative position of the boring bar and the boring bar is not adjusted frequently.
It is used in production, which indicates that the boring bar is clamped reliably, the radial feed of the cutter body is adjusted conveniently and quickly, the mechanism has no influence on the rigidity of the cutter body, the machining process is good, the structure is simple, and the practicability is strong. It should be pointed out that the boring bar of this structure is only suitable for large and medium-sized boring machines. For small boring machines or boring small holes, it is difficult to apply because of its small arbor.
