Detailed Description
To make the objects, contents and advantages of the present utility model more apparent, the following detailed description of the specific embodiments of the present utility model will be given.
The utility model provides a lathe milling groove device which is used for processing a 4mm key groove, and mainly comprises a milling cutter (3), a drill chuck (4), a ball roller bearing (5), a mandrel (6), an electric hand drill (7), a fixed electric hand drill bracket (8) and a clamp body (9); one end of the mandrel (6) is fixedly connected with the electric hand drill (7), and the other end of the mandrel is positioned and self-locked with the drill chuck (4) through a small taper conical surface; the electric hand drill (7) is fixed on the fixed electric hand drill bracket (8); the mandrel (6) is inserted into two ball roller bearings (5) and then is arranged on the clamp body (9); the fixed flashlight rotating bracket (8) is fixedly connected with the clamp body (9); the drill chuck (4) is provided with a milling cutter (3).
The milling cutter is a 4mm keyway milling cutter, the lathe milling groove device is assembled before machining, and the assembly steps are as follows:
a) Taking down a drill chuck (4) carried by the electric hand drill (7) and adding a mandrel (6);
b) Positioning and self-locking the removed drill chuck (4) and the mandrel (6) through a small taper conical surface;
c) The electric hand drill (7) assembled in the previous step is fixed on a fixed electric hand drill bracket (8);
d) Penetrating two ball roller bearings (5) into a mandrel (6) and installing the mandrel on a clamp body (9);
e) The fixed flashlight rotating bracket (8) is connected with the clamp body (9) through bolts;
f) The drill chuck (4) is rotated by a special spanner against a needle, so that a fixed jaw of the drill chuck (4) is opened, the drill chuck (4) is rotated by the special spanner against the needle after the drill chuck (4) is put into the milling cutter (3), and the milling cutter (3) is firmly fixed on the drill chuck (4);
g) Finally, fixing the whole set of assembled lathe milling groove device on a small slide plate of a lathe;
During processing, a workpiece (2) is fixed on a lathe, and a lathe spindle is adjusted to a low-gear position, so that the workpiece (2) is ensured not to rotate; assembling a lathe milling groove device according to the steps shown in figure 1 and the above, fixing the device on a small lathe sliding plate, and enabling the center of a milling cutter (3) to coincide with the center of a workpiece (2) through gasket adjustment; rotating the small lathe slide plate by 2 degrees, so that the moving track of the small lathe slide plate is parallel to the 2-degree conical surface of the workpiece (2); moving the middle sliding plate to enable the milling cutter (3) to be in contact with the workpiece (2), and moving the small sliding plate to cut a key slot parallel to the 2-degree conical surface through multiple times of feeding, wherein the cutting amount of each time is 0.5mm, until the depth of the key slot is 2 mm; repeating the above work until the two ends of the workpiece (2) are milled with 2 groups of symmetrical key grooves with the depth of 2 mm.
The screw thread, the conical surface and the key groove are all of process sizes, so that the fixture is convenient to assemble, and the process sizes are required to be larger than the actual sizes of the workpieces in design. After the machining is completed, the workpiece (10) is removed as shown in fig. 2.
The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that modifications and variations could be made by those skilled in the art without departing from the technical principles of the present utility model, and such modifications and variations should also be regarded as being within the scope of the utility model.
