Abstract
The invention belongs to the turning technical field and relates to a threading tool feeding mechanism. The threading tool feeding mechanism is arranged on the guide rail of a turning lathe, and comprises a cross tool carriage capable of sliding on the guide rail, wherein a lead screw coaxial with the threading tool is arranged on the cross tool carriage, a spring collet opposite to the threading tool is fixed at the front end of the lead screw, a clamping handle for controlling the spring collet is arranged at the rear end of the lead screw, and a turning wheel is fixed on the body of the lead screw. The threading tool feeding mechanism is arranged separately from the threading tool, the threading tool is only capable of rotating, the feeding of a workpiece is controlled by the lead screw on the cross tool carriage, and therefore, the driving shaft of the threading tool is prevented from generating frictional resistance with the lead screw and the processing efficiency and precision of the threading tool are improved.
Description
Technical field
The invention belongs to turning technical field.
Background technology
Threading tool is a kind of cutter that is used for carrying out the machining of screw thread on turning machining tool.Threading tool is widely used in screw chasing and reparation.While using now threading tool cut and repair screw thread on lathe, its feed mechanism (being generally leading screw) is connected with threading tool driving shaft, makes threading tool feeding simultaneously in rotation, and the degree of depth of cutting is also controlled by feed mechanism.The shortcoming of such scheme is: because the driving shaft of threading tool is in rotation, leading screw coordinates with leading screw seat the feeding of controlling threading tool, because the athletic meeting of leading screw produces certain friction, make threading tool driving shaft be subject to certain rotational resistance, process length consuming time, lathe tool cutting force diminishes also easily affects the precision of cutting.
Summary of the invention
The invention is intended to provide a kind of threading tool feed mechanism that improves cutting precision and process time.
Object of the present invention can reach by following measures: threading tool feed mechanism, be arranged on lathe guide rail, comprise the cross-slide that can slide on guide rail, cross-slide is provided with the leading screw coaxial with threading tool, the front end of leading screw is fixed with the collet relative with threading tool, and leading screw rear end is provided with the clamping lever of control spring chuck; Wire lever is fixed with runner with it.
Technique scheme difference with the prior art is: the two ends of leading screw are respectively equipped with collet and clamping lever, thereby bullet is adjusted clamping lever and is made the expansion set of collet move generation clamping force, spring chuck is holding workpiece securely, slidably cross-slide is set on lathe guide rail, the rotating while leading screw of driven by rotating wheel leading screw is done rectilinear motion, collet also moves thereupon, because collet is relative with threading tool, collet moves the feeding that realizes workpiece, and the degree of depth of cutting is by the determining positions of cross-slide.Threading tool feed mechanism of the present invention and threading tool split arrange, threading tool is only rotated, the feeding of workpiece is controlled by the leading screw on cross-slide, has avoided like this threading tool driving shaft and leading screw to produce frictional resistance, has improved working (machining) efficiency and the precision of threading tool.
Further, described runner is belt wheel, and leading screw and belt wheel are one-body molded, more steady by band wheel drive leading screw.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of threading tool feed mechanism embodiment of the present invention.
The specific embodiment
As shown in Figure 1: threading tool feed mechanism, comprise cross-slide 1, leading screw seat 2 and leading screw 3, cross-slide 1 is positioned on lathe guide rail and can slides along guide rail, leading screw seat 2 be threaded with cross-slide 1 on, leading screw 3 is coaxial and be installed on leading screw seat 2 with threading tool.
The front end of leading screw 3 is fixed with collet 4, and the rear end of leading screw 3 is connected with clamping lever 5 and collet binding nut.Insert in the inner sleeve of collet 4 one end of rod-shaped workpiece, regulates clamping hand 5 that the expansion set of collet 4 and inner sleeve are subjected to displacement, thus clamping work pieces.
On the shaft of leading screw 3 with belt wheel 6, this belt wheel 6 and leading screw 3 one machine-shapings.Belt wheel 6 drives leading screw 3 to rotate while rotating, leading screw 3 is transformed into rectilinear motion by gyration under the effect of reverser, realizes the feeding of workpiece.
The foregoing is only the detailed description of preferred embodiment of the present invention, be not used for limiting the present invention, the embodiment of all similar variations of doing according to creation spirit of the present invention, all should be contained among the present invention.
