Example 1

The multi-angle positioning rotary vice, as shown in fig. 1-3, comprises a clamp main body 1 and a fixed seat 2, and in the example of fig. 1, the clamp main body 1 is arranged at the front side of the fixed seat 2 and is in rotary connection with the fixed seat 2.

As shown in fig. 2 and 3, the clamp body 1 is rotatably connected with the fixing seat 2 through a rotating shaft 3, as shown in fig. 3, a shaft hole 101 is formed in the clamp body 1, the shaft hole 101 is specifically formed in a later-described clamp seat 1-1, as shown in fig. 2, the rotating shaft 3 is arranged on the shaft hole 101 in a penetrating manner, and one end of the rotating shaft 3 penetrating through the fixing seat 2 is in threaded connection with a locking nut 4 so as to prevent the clamping body from falling out.

In this embodiment, as shown in fig. 1, the clamp body 1 includes: the clamp seat 1-1, the fixed jaw 1-2, the movable jaw 1-3 and the screw rod 1-4.

The clamp seat 1-1 is in a rectangular block structure, and a groove 102 is provided on the front surface of the clamp seat 1-1 along the length direction, so as to avoid affecting the movement of the movable jaw 1-3, an opening of the groove 102 is provided with a rounded corner, but the shape of the groove 102 is not particularly limited in this embodiment.

The fixed jaw 1-2 is fixed at the bottom of the clamp seat 1-1, the fixed jaw 1-2 is in a T-shaped structure, and the T-shaped end of the fixed jaw 1-2 extends into the groove 102.

The movable jaw 1-3 is distributed opposite to the fixed jaw 1-2, and is movably arranged along the clamp seat 1-1, the movable of the movable jaw 1-3 is realized by a screw rod 1-4, the screw rod 1-4 is embedded in the groove 102 and is arranged at intervals with the groove wall of the groove 102 so as to avoid affecting the rotation of the screw rod 1-4, the screw rod 1-4 is arranged on the movable jaw 1-3 in a penetrating way and is in threaded connection with the movable jaw 1-3, and one end of the screw rod 1-4 penetrating through the movable jaw 1-3 is movably arranged on the fixed jaw 1-2 in a penetrating way. When the screw 1-4 rotates, the movable jaw 1-3 moves along the screw 1-4 due to the action of the threads, thereby realizing clamping or loosening of the workpiece.

In order to drive the screw 1-4 to rotate, the clamp body 1 of the present embodiment further includes a handle (not shown in the figure), which is detachably connected to the screw 1-4 through a connector at the end of the screw 1-4, and the screw 1-4 can be rotated by operating the handle.

In this embodiment, as shown in fig. 2, the height of the fixing base 2 is smaller than that of the clamp body 1, so as to expose a part of positioning holes 103, which will be described later, for facilitating insertion of positioning pins 104, which will be described later. Specifically, the fixing seat 2 is in an L-shaped structure, that is, the fixing seat 2 is composed of a vertical section and a horizontal section, the vertical section and the clamp seat 1-1 are distributed in parallel, and the rotating shaft 3 is arranged on the vertical section in a penetrating manner. The shape of the fixing base 2 is not limited to this.

In this embodiment, the clamp body 1 and the fixing seat 2 are rotationally connected through the rotating shaft 3, so that any angle rotation of the clamp body 1 can be realized, for example, the clamp body 1 is limited at a rotation angle, as shown in fig. 2 and 3, a plurality of positioning holes 103 are formed in the clamp seat 1-1, and positioning pins 104 are inserted into the positioning holes 103, so that the clamp body 1 is limited.

Specifically, the positioning holes 103 in this embodiment are provided with eight positioning holes 103, and the eight positioning holes 103 are uniformly distributed in a ring shape, and at this time, the shaft hole 101 is located at the center of the ring formed by the eight positioning holes 103.

When the rotary vice of the embodiment is used, the clamp main body is rotated to a proper angle, and then the locating pin is inserted into the corresponding locating hole, so that the clamp main body can be limited, the clamp main body can be machined at a specific angle conveniently, the problem that certain angles cannot be located in the existing machining is solved, and the machining efficiency is improved.

Example 2

As shown in fig. 4, unlike the embodiment 1, the rotary vice with multi-angle positioning further comprises a positioning block 5, when the clamp body 1 rotates to a certain angle, if a gap exists between the positioning pin 104 and the fixing base 2, positioning is inaccurate, and at this time, accurate positioning can be achieved by clamping the positioning block 5 between the fixing base 2 and the positioning pin 104, thereby improving machining precision.

The state of the rotary vice of the present embodiment when performing multi-angle positioning is shown in fig. 5 to 8, wherein fig. 5 is a state when the clamp body 1 rotates 5 ° counterclockwise, fig. 2 is a state when the clamp body 1 rotates 19 ° counterclockwise, fig. 3 is a state when the clamp body 1 rotates 26 ° counterclockwise, and fig. 4 is a state when the clamp body 1 rotates 28 ° clockwise.

As can be seen from fig. 4 to 8, the shape of the positioning block 5 in the present embodiment can be adjusted according to needs, so that the positioning block 5 can be tightly attached to the fixing seat 2 and the positioning pin 104, thereby realizing any angle rotation of the clamp body 1.

It should be noted that modifications and improvements can be made by those skilled in the art without departing from the inventive concept, and these are all within the scope of the present utility model.
