It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0015] Refer to Figures 1-3 A rotary multi-purpose positioning and clamping mechanism for machine tool shaft parts shown in the figure, which includes a rotating platform 1 and a support base 2. A turntable 3 is fixedly connected to the rotating table of the rotating platform 1. A plurality of positioning assemblies are arranged on the turntable 3. According to the specifications of the machine tool shaft parts, the rotating platform 1 drives the turntable 3 to rotate 90° in sequence, so that the positioning assembly to be used rotates to the corresponding position with the support base 2 to complete the adjustment. The positioning assembly includes a C-shaped frame 401, an upper positioning plate 402 and a lower positioning plate 403. The upper positioning plate 402 and the lower positioning plate 403 are respectively fixedly connected to both ends of the C-shaped frame 401. The C-shaped frame 401 is fixedly connected to the side wall of the turntable 3. A pressing cylinder 5 is fixedly connected to the support base 2. The support base 2 is arranged corresponding to the notch of the C-shaped frame 401. A side pressing plate 501 is fixedly connected to the piston rod of the pressing cylinder 5. A base 6 is arranged between the rotating platform 1 and the support base 2. A lifting cylinder 7 is arranged on the base 6.
