Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
The spindle rotary joint structure of the vertical machining center of the embodiment is shown in fig. 1 to 3 and comprises a rotary joint 1 and a shuttle valve 2, wherein the rotary joint 1 is installed on a spindle 3, the shuttle valve 2 is installed on an installation mechanism, the up-down and left-right positions of the shuttle valve 2 are adjustable, the installation mechanism is installed on a unclamping cylinder support 4, one end of the shuttle valve 2 is connected with the upper end of a rubber pipe 61 through a first joint 51, the lower end of the rubber pipe 61 is connected with one end of a steel pipe 62 through a second joint 52, and the other end of the steel pipe 62 is connected with the rotary joint 1 through a third joint 53.
In this embodiment, the mounting mechanism includes a first bracket 71, a second bracket 72 and a back plate 73, which are vertically arranged, the second bracket 72 is mounted on the unclamping cylinder support 4, the first bracket 71 is mounted on the upper side of the second bracket 72 in a manner of moving left and right, first kidney-shaped holes 74 are respectively formed in the first bracket 71 and the second bracket 72, which are opposite in position, first screws (not shown in the figure) penetrate through the first kidney-shaped holes 74, and the first screws are used for connecting the first bracket 71 and the second bracket 72; the back plate 73 is disposed on the back of the first bracket 71 to be movable up and down, a second waist-shaped hole 75 is formed in the first bracket 71, and a second screw (not shown) penetrates through the second waist-shaped hole 75 and is used for connecting the first bracket 71 and the back plate 73.
