Description
Technical Field
The utility model relates to a machine tool clamp technical field especially relates to a non-round bar body centre gripping frock for lathe.
Background
The three-jaw chuck is a common machine tool clamp, and utilizes the radial movement of three movable jaws uniformly distributed on a chuck body to clamp and position a workpiece on a machine tool, thereby realizing the self-centering of the workpiece, and having simple and convenient operation and very wide application.
The three-jaw chuck is generally only suitable for clamping workpieces such as round bars, but is difficult to be applied to non-round bars. For example, a cylindrical rod with a plane on one side is processed, and during clamping, one movable clamping jaw cannot be in contact with a workpiece, and the workpiece cannot be clamped due to lack of a supporting surface, so that improvement is needed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a non-round bar body centre gripping frock for lathe realizes containing the centre gripping of planar cylinder barred body to one side, promotes application scope.
To achieve the purpose, the utility model adopts the following technical proposal:
the utility model provides a non-round bar body centre gripping frock for lathe, includes: three-jaw chuck, push pedal and screw rod, annular array is provided with three movable jack catch on the three-jaw chuck, the push pedal is located the front of three-jaw chuck, the push pedal back is perpendicular with the direction of activity of one of them movable jack catch, and all the other two movable jack catches are the front of directional push pedal respectively, the symmetry is provided with the baffle that is located the positive the place ahead of push pedal on the three-jaw chuck, the screw rod sets up on the baffle and runs through the push pedal perpendicularly, be provided with the first nut that is located the push pedal back on the screw rod.
Wherein, a through hole corresponding to the screw rod is arranged on the push plate.
And a second nut or a spring positioned on the front surface of the push plate is arranged on the screw rod.
The three-jaw chuck is provided with a sliding groove parallel to the screw rod, a sliding block corresponding to the pushing plate is arranged in the sliding groove, and the pushing plate is provided with a screw connected with the sliding block.
Wherein, the spout is the dovetail.
The utility model has the advantages that: the utility model provides a lathe is with non-round bar body centre gripping frock, through the arc surface contact of two movable jack catchs and non-round bar body and realize from feeling relieved, the rotatory promotion that carries out the push pedal of rethread first nut for the push pedal openly hugs closely on non-round bar body's plane, realizes pressing from both sides the clamp of non-round bar body, and the centre gripping of specially adapted semi-circular bar body, dismouting are convenient, have expanded application scope.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The technical solution of the present invention is further explained by the specific embodiment with reference to fig. 1.
The non-round rod clamping tool for the machine tool shown in figure 1 comprises: three-jaw chuck 1, push pedal 6 and screw rod 4, annular array is provided with three movable jaw 2 on the three-jaw chuck 1, and three movable jaw 2 synchronous motion can carry out the centre gripping of round bar body, but can't the centre gripping to the semicircular rod body.
The push pedal 6 is located the front of three-jaw chuck 1, the push pedal 6 back is perpendicular with the direction of activity of one of them movable jack catch 2, and all the other two movable jack catches are oblique directional push pedal 6's front respectively, the symmetry is provided with baffle 3 that is located the positive the place ahead of push pedal 6 on the three-jaw chuck 1, and baffle 3 welding perhaps adopts the bolt fastening to be positive at three-jaw chuck 1, sound construction.
The screw rod 4 is arranged on the baffle 3 and vertically penetrates through the push plate 6, and the push plate 6 is provided with a through hole corresponding to the screw rod 4, so that the installation is convenient. The screw rod 4 is provided with a first nut 7 positioned on the back of the push plate 6, the push plate 6 is pushed by the rotation of the first nut 7, so that the push plate 6 is in contact with the plane on the semicircular rod body and is matched with the two movable clamping claws to clamp and position the semicircular rod body.
Be provided with on the screw rod 4 and be located the positive second nut or the spring 10 of push pedal 6, carry on spacingly to push pedal 6, avoid droing, especially spring 10, first nut 7 unscrews the back, can realize pushing pedal 6's quick reset, makes things convenient for taking off of semi-circular barred body.
The three-jaw chuck is characterized in that a sliding groove 5 parallel to the screw rod 4 is formed in the three-jaw chuck 1, a sliding block 9 corresponding to the push plate 6 is arranged in the sliding groove 5, the sliding groove 5 is a dovetail groove, the sliding block 9 is a trapezoidal block, sliding guiding of the sliding block 9 is achieved through the sliding groove 5, and stability is high.
The push plate 6 is provided with a screw 8 connected with the sliding block 9, so that the push plate 6 and the sliding block 9 are synchronized, the sliding block 9 is utilized to improve the moving stability of the push plate 6, the deviation is avoided, and the workpiece is clamped more stably.
The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
