The micro-head is propped against the rear end, and the semi-finished cutting depth is finely adjusted by rotating the micro-cylinder, so that the semi-finished cutting depth is controlled.
The measuring range of the differential head is 0-6.5 mm, the precision is +/-2 mu m, and the minimum adjustment scale is 0.01mm.
The height difference D between the finish turning blade and the rough turning blade is the cutting depth of semi-finish turning, and the height difference D is finely adjusted through a micro-head.
The rough turning blade and the finish turning blade are indexable blades.
When the workpiece is turned, the rough turning blade is contacted with the workpiece to finish rough turning, the finish turning blade is contacted with the workpiece, and the cutting depth of the finish turning does not exceed the maximum value of the differential head to finish turning.
The knife handle is made of a No. 45 steel material.
The utility model is provided with two turning tools, can realize the simultaneous turning of the rough turning blade and the finish turning blade, namely one-time feeding, and does not need to adjust a cutter to realize rough machining and semi-finish machining, thereby saving the machining time and improving the machining efficiency.
Drawings
Fig. 1 is a schematic view of an angle structure of the present utility model.
FIG. 2 is a schematic view of another angle structure of the present utility model.
Fig. 3 is a right-hand view of the turning tool of the present utility model.
Fig. 4 is a partial enlarged view of fig. 1.
In the figure: the tool comprises a 1-finish turning blade, a 2-locking screw, a 3-finish turning tool bit, a 4-finish turning tool bar, a 5-tool shank, a 6-locking bolt, a 7-locking nut, an 8-differential head, a 9-rough turning tool bit, a 10-pressing bolt, an 11-pressing plate, a 12-locking screw and a 13-rough turning blade.
Detailed Description
The present utility model will be described in further detail below with reference to the drawings and specific embodiments for the understanding of those skilled in the art.
1-2, a combined turning tool for simultaneously performing rough machining and semi-finish machining comprises a tool handle (5), a rough turning tool bit (9), a finish turning tool bit (3), a rough turning blade (13) and a finish turning blade (1); the rough turning tool bit (3) is fixed on the tool shank; the finish turning tool bit (3) and the finish turning tool bar (4) are connected into a whole and inserted into the tool shank (5); the rough turning blade (13) and the finish turning blade (1) are arranged side by side along the feeding direction and are detachably arranged on the cutter head; the finish turning blade (1) protrudes from the rough turning blade (13) along the H direction which is perpendicular to the side surface of the cutter head.
1-4, a combined lathe tool for simultaneously carrying out rough machining and semi-finish machining is applied to machining shaft workpieces, when the combined lathe tool is applied, a cutter handle (5) of the combined lathe tool is installed on a lathe, during machining, the workpiece rotates, the lathe tool moves in a feeding mode, materials to be machined of the shaft workpieces are removed, as a rough turning blade (13) and a finish turning blade (1) are arranged in a front-back mode, the rough turning blade (13) has large cutting depth and is responsible for rough machining, the finish turning blade (1) has small cutting depth and is responsible for semi-finish machining, the rough turning blade (13) firstly cuts the workpiece, the finish turning blade (1) cuts the workpiece, rough machining and semi-finish machining of the workpiece are finished simultaneously, procedures are reduced, machining time is shortened, and production efficiency is improved.
