Fig. 2 is a schematic structural diagram of the first embodiment.
Fig. 3 is a schematic structural diagram of the second embodiment.
In the figure: 1L-shaped claw block, 2 mounting surfaces, 3 positioning surfaces, 4 claw nails, 5 claw rings, 6 cap bodies and 7 bolts.
Detailed Description
The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.
According to the illustrations of fig. 1 to 3: the embodiment provides a multi-point floating soft jaw, which comprises three or four radially distributed L-shaped jaw blocks 1, although the number of the jaw blocks of the L-shaped jaw block 1 can be set to be more, the assembly is selected mainly according to the chuck structure assembled by the L-shaped jaw block 1, so that the multi-point floating soft jaw is suitable for a three-jaw chuck and a four-jaw chuck, and the specific implementation structure of the L-shaped jaw block 1 is as follows.
The side surface of the inner side of the L-shaped claw block 1, which faces the front side, is a positioning surface 3, the positioning surface 3 is of a planar structure, the side surface of the inner side of the L-shaped claw block 1, which faces the middle part, is an installation surface 2, and the middle part of the installation surface 2 is arched outwards to form an arc surface structure;
the mounting surface 2 is provided with a claw ring 5, the claw ring 5 is an arc-shaped panel, one side of an arc-shaped opening of the claw ring 5 faces the middle part, the middle part of the claw ring 5 is connected with the mounting surface 2 through a bolt 7, the bolt 7 penetrates through the middle part of the claw ring 5 to be arranged, a nut of the bolt 7 is positioned on the inner side of the claw ring 5, a screw end of the bolt 7 is positioned on the outer side of the claw ring 5 and is fixedly connected with the mounting surface 2 in a threaded manner, the claw ring 5 is freely arranged on the outer side of a screw of the bolt 7, and the inner diameter of a through hole reserved on the claw ring 5 is slightly larger than the diameter of the screw, so that the claw ring 5 can perform sliding, rotating and deflection actions on the outer side of the bolt 7, is used; 5 both sides of claw circle are equipped with a set of claw nail 4 respectively, claw nail 4 perpendicular to claw circle 5 sets up, claw nail 4 with 5 threaded connection of claw circle are fixed and 4 tip of claw nail are located 5 inboards of claw circle, claw nail 4 are located 5 inboard tip outsides of claw circle still are equipped with rather than threaded connection fixed and the surperficial slick and sly cap body 6, and 6 outsides of cap body are used for pressing from both sides tight blank and use, can avoid causing damage such as mar to the blank surface.
The multi-point floating soft claw is characterized in that the L-shaped claw block 1 and the claw ring 5 are not integrated, the claw ring 5 and the L-shaped claw block 1 are connected in a non-fastening mode through the bolt 7, six claw nails 4 are arranged on the claw ring 5 to form the six-point floating soft claw or the eight-point floating soft claw, and the soft claw is arranged on a hydraulic chuck of a machine tool;
in the multi-point floating soft claw working process, the claw ring 5 clamps the blank through six or eight claw nails 4 in the radial moving process of the L-shaped claw block 1, the cambered surface structure of the mounting surface 2 can lead the claw ring 5 to move better when clamping the blank, and the claw nails 4 and the blank are better in contact, so that the stress is more sufficient and more uniform when the blank is clamped, the workpiece is not easy to deform, the roundness of the workpiece is not easy to exceed the tolerance, the claw ring 5 is mounted on the inner surface, and the claw ring 5 is also guaranteed to be stressed radially, and the service life of the clamp is prolonged.
The above is only the preferred embodiment of the present invention, as long as the preferred embodiment is realized by the same means, the objective technical solution of the present invention all belongs to the protection scope of the present invention.
