Description
Technical Field
The utility model relates to the field of special fixtures of machining lathe equipment, in particular to a lathe claw capable of being quickly replaced.
Background
In machining, a lathe is a machine tool that mainly turns a rotating workpiece with a lathe tool. The lathe can also be used for corresponding processing by using a drill bit, a reamer, a screw tap, a die, a knurling tool and the like. When the lathe is used for processing a workpiece, the workpiece is clamped by the clamping jaws on the chuck, and then turning is performed. The common claw is divided into a hard claw and a soft claw, the hard claw is generally a claw originally matched with a lathe chuck, the hardness is higher after quenching, the hard claw is used for roughly turning a bar material, turning a blank and the like, the clamping is firm, and the clamping force is large. The soft claw is generally formed by welding soft steel, copper and aluminum materials on the basis of the hard claw. The soft claw is generally used for secondary clamping, can be used after being turned and corrected, can improve the coaxiality of a workpiece, is used during finish machining, and has small clamping force. The soft claw is manufactured by machining the hard claw and the claw body to required sizes before welding and then welding, which is troublesome. There is a need for a more rapid way to improve the efficiency of soft jaw replacement.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
The technical problem to be solved by the utility model is as follows: aiming at the defects that the existing lathe soft claw is manufactured by welding, the working procedure consumes time and has no interchangeability, the existing soft claw adopting a bolt connection mode can realize quick replacement of the lathe soft claw and has interchangeability.
(II) technical scheme
In order to solve the technical problem, the utility model provides a lathe jaw capable of being replaced quickly, which comprises a chuck 1, a hard jaw body 2 and a soft jaw body 3;
the chuck is a cylinder, and a hole is formed in the center of the circle; the hard claw body 2 is fixed on the upper surface of the chuck 1, and the soft claw body 3 and the hard claw body are detachably arranged;
The soft claw body 3 is provided with a trapezoidal section at one end close to the circle center of the chuck 1.
Wherein, the hard claw body 2 is the cuboid structure, and quantity is 3, and its tip is close to the 1 centre of a circle of chuck, and the other end evenly sets up on chuck 1 along radial.
Wherein, first screw hole radially sets up along chuck 1, and first screw hole number is 2.
Wherein, the countersunk head bolt is a countersunk head inner hexagonal bolt 4.
(III) advantageous effects
Compared with the prior art, the utility model has the following beneficial effects:
(1) the soft claw body with the threaded hole of the sinking platform is designed, and the hard claw body and the soft claw body are connected by the bolt and the threaded hole to play a role in pressing.
(2) The inner hexagonal bolt is adopted, so that the bolt can sink below the surface of the soft claw body, and the interference with a workpiece is avoided when the workpiece is cut.
(3) The hard claw body is also provided with a threaded hole which plays a role in connecting the soft claw and accurately positioning, so that the soft claw has interchangeability.
Drawings
FIG. 1 is a schematic structural composition of the present invention;
fig. 2 is a locking view of the soft claw body.
In the figure, 1-chuck, 2-hard claw body, 3-soft claw body and 4-countersunk inner hexagonal bolt.
Detailed Description
In order to make the objects, contents, and advantages of the present invention clearer, the following detailed description of the embodiments of the present invention will be made in conjunction with the accompanying drawings and examples.
In order to solve the problems, the utility model provides a lathe jaw capable of being replaced quickly, which comprises a chuck 1, a hard jaw body 2 and a soft jaw body 3, as shown in fig. 1-2;
the chuck is a cylinder, and a hole is formed in the center of the circle; the hard claw body 2 is fixed on the upper surface of the chuck 1, and the soft claw body 3 and the hard claw body are detachably arranged;
The soft claw body 3 is provided with a trapezoidal section at one end close to the circle center of the chuck 1.
Wherein, the hard claw body 2 is the cuboid structure, and quantity is 3, and its tip is close to the 1 centre of a circle of chuck, and the other end evenly sets up on chuck 1 along radial.
Wherein, first screw hole radially sets up along chuck 1, and first screw hole number is 2.
Wherein, the countersunk head bolt is a countersunk head inner hexagonal bolt 4.
Example 1
Referring to fig. 1, the chuck 1 according to the present invention is illustrated in connection with the present embodiment as a cylindrical body which is a component inherent to a lathe itself and has a screw thread on an inner end surface; the hard claw 2 is in threaded connection with the chuck close to the inner end surface; the soft claw body 3 is a cuboid, a large chamfer is arranged at the front end, two threaded holes are formed in the middle, and the soft claw body 3 and the hard claw body 2 are connected and locked through bolts 4. When the soft claw is used for multiple times, after repeated turning, the bolt can be loosened by using an internal hexagonal wrench, the soft claw body 3 and the hard claw body 2 are disassembled, a new soft claw body is taken and is locked with the hard claw body 2 again, and the soft claw can be used again, so that the traditional method of re-welding every time is avoided.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
