[0037] In view of the problems mentioned in the above background technology, the embodiment of the utility model provides a rotary precision bench vise to solve the above technical problems, and its technical solution is as follows:

[0038] A rotary precision bench vise, comprising:

[0039] A vise body, a locking pipe, a support assembly, a ball joint 160 and a first bolt 240;

[0042] The stand pipe 320 is welded on the base 310; the stand pipe 320 not only plays a supporting role, but also the tube cavity opening at the top of the stand pipe 320 is used to receive the ball joint 160 so that the ball joint 160 is stuck on the tube cavity opening at the top of the stand pipe 320;

[0043] The connecting plate 341 is welded to the side wall of the riser 320;

[0044] The column 342 is welded to the bottom of the connecting plate 341;

[0045] The protrusion 343 is welded on the top of the connecting plate 341 and is located directly above the column 342. The protrusion 343 is provided so that when the nut 250 is tightened later, the protrusion 343 provides a force point after the nut 250 is tightened.

[0046] A first through hole 344 is provided vertically and vertically between the protrusion 343, the connecting plate 341 and the column 342;

[0047] The locking pipe includes a first pipe sleeve 210 and a second pipe sleeve 220 connected to each other; and the cavity of the first pipe sleeve 210 and the cavity of the second pipe sleeve 220 are connected.

[0048] The first sleeve 210 is sleeved on the vertical pipe 320, and the second sleeve 220 is sleeved on the protrusion 343, the connecting plate 341 and the column 342;

[0049] The axial length of the second sleeve 220 is smaller than the vertical height of the projection 343, the connecting plate 341 and the column 342 after being superimposed. This arrangement is to allow the bottom of the column 342 to be exposed from the second sleeve 220, so as to facilitate the insertion of the first bolt 240 upward from the first through hole 344 at the bottom of the column 342.

[0050] The ball joint 160 is mounted on the tube cavity opening at the top of the riser 320 and is located in the first tube sleeve 210; the diameter of the tube cavity of the riser 320 is smaller than the diameter of the ball joint 160;

[0051] An annular rib 212 is disposed at the top of the first sleeve 210. The inner diameter of the annular rib 212 is smaller than the diameter of the spherical joint 160, so as to prevent the spherical joint 160 from slipping off the annular rib 212.

[0052] The top of the second sleeve 220 is sealed by welding the plate, and the plate is provided with a second through hole 221 coaxial with the first through hole 344;

The third through hole 322, the fourth through hole 213, and the second bolt 260 are provided to press the first pipe sleeve 210 onto the vertical pipe 320.

[0055] Tightening the nut 250 can lock the ball joint 160 between the tube cavity opening at the top of the stand pipe 320 and the annular rib 212 of the first sleeve 210 .

[0056] The method for rotating the main body of a rotary precision bench vise provided by the embodiment of the utility model is as follows:

[0057] 1. When the vise body needs to be rotated, loosen the nut 250, and control the vise body to rotate the ball joint 160 in the first sleeve 210 and on the tube cavity opening at the top of the stand pipe 320 until it is rotated to a suitable position;

[0058] 2. Tighten the nut 250 to press the top plate of the second sleeve 220 against the protrusion 343. At this time, since one side of the first sleeve 210 is locked on the stand pipe 320 by the second bolt 260, the other side of the first sleeve 210 is pressed toward the second sleeve 220 until the ball joint 160 is firmly locked between the tube cavity opening at the top of the stand pipe 320 and the annular rib 212 of the first sleeve 210. The circumferential rotation of the ball joint 160 is restricted, and the angular rotation operation of the vise body is completed.
