Abstract
The utility model relates to the technical field of inner thread processing, in particular to an inner thread processing device for a numerical control machine tool. In the traditional inner thread processing method, a screw tap is fixed on a tool rest; and a workpiece is fixed on a chuck and rotates at certain rotating speed. As an operator is very hard to lead the feeding speed of the screw tap to be consistent to the screwing-in speed caused by rotation of the workpiece, the screw tap is extremely easy to be broken. The inner thread processing device consists of the screw tap, a sliding sleeve, fastening screws, a positioning pin and a fixed sleeve, wherein a screw tap handle part is arranged in a horizontal hole of the sliding sleeve, and the two parallel fastening screws penetrate through the upper part of the left end of the sliding sleeve to fix the screw tap; a boss at the left end of the sliding sleeve is limited, and the excircle at the right end of the sliding sleeve is movably matched with an inner hole at the left end of the fixed sleeve; the left-lower end of the fixed sleeve is provided with a guide groove, the positioning pin penetrates through the guide groove of the fixed sleeve to be fixed with the sliding sleeve together by threads; and the workpiece, the screw tap, the sliding sleeve and the fixed sleeve are coaxial, and the right end of the fixed sleeve is fixedly connected with the tool rest. In the inner thread processing device, the structure is simple and the production efficiency is high.
Description
Technical field
The utility model relates to a kind of internal thread machining technical field, specifically a kind of numerically controlled lathe female thread machining device.
Background technology
Traditional female thread machining method is that screw tap is fixed on the knife rest, and workpiece is fixed on the chuck with certain rotating speed rotation.In process, because of threaded function, screw tap screws in workpiece with certain speed.Need the manual tool slide of operator, to cooperate the screw-in speed of screw tap.But the operator is difficult to make the feed speed of screw tap consistent with the screw-in speed of the screw tap that causes because of the workpiece rotation, to such an extent as to screw tap is very easily broken.So traditional method is difficult to machining internal thread, and efficient is extremely low.
Summary of the invention
The purpose of this utility model provides a kind of numerically controlled lathe female thread machining device, can solve in traditional internal thread machining process, and screw tap is easily broken, inefficient problem.
The technical scheme that its technical problem that solves the utility model adopts is: female thread machining device comprises screw tap, also form by slip cap, holding screw, alignment pin and fixed cover, tap holder is deployed in the lateral aperture of slip cap, and the screw hole that two holding screws that be arranged in parallel pass above the slip cap left end is fixed on screw tap on the slip cap; Slip cap left end boss is spacing, right-hand member cylindrical and fixed cover left end endoporus movingly; Fixed cover lower-left bottom portion has gathering sill, and alignment pin inserts in the gathering sill of fixed cover, is fixed together with screw thread with slip cap; Screw tap, slip cap and fixed cover are coaxial, and fixed cover right-hand member and knife rest are connected and fixed.
The beneficial effects of the utility model are, in the internal thread working angles, knife rest is motionless, and the screw tap auto-feed when working depth is enough, only needs reverse-starting braking operation, and screw tap can withdraw from automatically, and screw tap can not broken, the production efficiency height.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1: be working state schematic representation of the present utility model;
Fig. 2: for the A of Fig. 1 to partial view.
Among the figure: 1. screw tap, 2. slip cap, 3. holding screw, 4. alignment pin, 5. fixed cover.
The specific embodiment
As shown in the figure, female thread machining device comprises screw tap 1, also form by slip cap 2, holding screw 3, alignment pin 4 and fixed cover 5, the 1/3-1/2 of screw tap 1 shank length places the lateral aperture of slip cap 2, and the screw hole that two holding screws that be arranged in parallel 3 pass above slip cap 2 left ends is fixed on screw tap 1 on the slip cap 2; Slip cap 2 left end boss are spacing, right-hand member cylindrical and fixed cover 5 left end endoporus movingly; Fixed cover 5 lower-left bottom portion has gathering sill, and alignment pin 4 inserts in the gathering sill of fixed cover 5, is fixed together with slip cap 2 usefulness screw threads; Screw tap 1, slip cap 2 and fixed cover 5 are coaxial, and fixed cover 5 right-hand members and knife rest are connected and fixed.
In process, the workpiece rotation, when being cut screw thread by screw tap, because the effect of screw thread drives screw tap and screws in workpiece, because screw tap, slip cap, holding screw, alignment pin can endwisely slip in the gathering sill integral body of fixed cover, so screw tap can not broken in the sliding stroke scope, because the effect of alignment pin, screw tap can not rotate yet, thereby the internal thread cutting is carried out.The operator need not be to the screw tap hand feed, when cutting internal thread during, operator's reverse-starting braking operation to enough degree of depth, and the workpiece counter-rotating, because threaded function, screw tap, slip cap, holding screw, alignment pin reverse slide, screw tap withdraws from from workpiece, and the internal thread cutting finishes.
