At the same time, the welded parts are heavy, and when the position needs to be rotated, the heavy volume cannot be easily rotated, which makes operation inconvenient.

[0004] CN2017206537353 discloses a fixture device with two degrees of freedom, synchronous rotation, and multi-angle swing positioning, and a fixture workbench using the fixture device. The fixture device includes a fixed base, a rotary support located above the fixed base, a left support column and a right support column located above the rotary support, and a pneumatic fixture suspended between the left and right support columns. A two-degree-of-freedom rotation transmission assembly is respectively connected to the rotary support and the fixture head of the pneumatic fixture. The left support column is provided with a rotary swing assembly for driving the pneumatic fixture for multi-angle rotation and swing positioning. The rotary swing assembly uses a transmission structure in which a graduated cylinder drives a power output shaft through a rack and pinion transmission combination, wherein the output end of the power output shaft is further fastened to the fixture base of the pneumatic fixture. A five-angle rotary swing positioning structure is provided. Utility Model Content
