[0046] The fixture mounting rack 1 provided by the embodiment is capable of rotating the support body 104 connected to the top of the moving seat 102 in the process of sliding of the moving seat 102 by the cooperation of the moving seat 102, the rotating shaft 103, the hinged connecting rod 108, and the slider 107 and the bent slide 106. The fixture installed on the upper end of the support body 104 is capable of turning in the direction away from the clamped workpiece by using this feature.

[0047] In some embodiments, the bent reversing part is arc-shaped and ensures smooth transition of the slider 107, and has a reversing angle of 90 degrees, i.e. the two sections of the bent slide 106 are horizontal section and vertical section respectively. When the moving seat 102 starts to move, the rotating shaft 103 on the moving seat 102 moves along a straight line first, and this movement trend is transmitted to the hinged connecting rod 108 to drive the hinged connecting rod 108 to move along a straight line and the slider 107 at the other end of the hinged connecting rod 108 to slide in the horizontal section of the bent slide 106. When the slider 107 passes the bent reversing part, it moves downward and drives the end of the hinged connecting rod 108 connected thereto to move downward, and the movement direction changes by 90 degrees. Under the action of the pin shaft 116, the hinged connecting rod 108 rotates and drives the rotating shaft 103 fixed at the other end of the hinged connecting rod 108 to rotate by 90 degrees. The slider 107 is kept stationary at the two end portions of the bent slide 106 respectively, and when the slider 107 is at the end portion of the horizontal section, the support column 104 is in the state of being vertically fixed to the upper end of the fixed seat 101, and when the slider 107 is at the end portion of the vertical section, the support column 104 is in the state of being rotatably fixed to the upper end of the fixed seat 101. The technical solution of the embodiment can control the swing amplitude of the support column 104, and can be matched with the actual processing and production scene to keep a suitable distance from the clamped workpiece and reserve a suitable space.

[0048] Specifically, to make the slider 107 slide more smoothly, the horizontal section of the bent slide 106 is set to be flush with the rotating shaft 103 in height, i.e. when the slider 107 is in the horizontal section, the hinged connecting rod 108 is also in the horizontal state. Therefore, when the moving seat 102 starts to move, the rotating shaft 103, the hinged connecting rod 108, and the slider 107 are in the same straight line, and the stress direction is in the same straight line, so that the slider 107 can be driven more smoothly.

[0049] In some embodiments, the driving part 109 is a cylinder, the mounting end of which is fixedly connected with the upper end surface of the fixed seat 101, specifically, one side of the moving seat 102, the extension end of which is parallel to the moving direction of the moving seat 102, and is flush with one end of the moving seat 102 in the horizontal direction in the state of not being extended.

In this embodiment, the rotating shaft 103 is suspended by the U-shaped rotating shaft mounting rack 112, so as to reduce the obstacles in the rotating direction of the rotating shaft 103 as much as possible, so that the support column 104 can rotate by a larger angle. And enough area is reserved between the two side plates of the U-shaped rotating shaft mounting rack 112 for the installation of the support column 104 on the rotating shaft 103.

[0051] On the basis of the last embodiment, two bearings 113 are further included, which are respectively assembled in the two shaft holes, so as to protect the rotating shaft 103 and reduce the wear of the rotating shaft 103.
