Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
Referring to fig. 1 to 3, the present embodiment provides a positioning device for clamping an eccentric shaft, including a positioning seat 1, a portal frame 2 fastened to two opposite side walls of the positioning seat 1, a locking member 3 disposed in the middle of a cross beam of the portal frame 2 and used for cooperating with the positioning seat 1 to clamp the eccentric shaft to be tested, and positioning sliders disposed on two opposite sides of the locking member 3 and slidably connected to the positioning seat 1. With this structural design, press from both sides tightly eccentric shaft 5 through retaining member 3 and positioning seat 1, press from both sides tight eccentric shaft 5 in-process, rotatory eccentric shaft 5 makes the outer peripheral face tangent the setting with the location slider of both sides respectively, later moves the eccentric shaft 5 that the clamping is good to the three-coordinate machine tool and detects.
Specifically, the positioning seat 1 in this embodiment includes a base 11, a slide rail 12 disposed on an upper surface of the base 11, and a positioning wall 13 disposed on an upper surface of the slide rail 12, where the positioning wall 13 is provided with a first arc-shaped notch 131 for erecting the eccentric shaft 5; the locking piece 3 comprises a screw 31 vertically penetrating through the middle of a cross beam of the portal frame 2, a knob 32 arranged at the upper end of the screw 31, and a pressing block 33 pivoted to the lower end of the screw 31, a pressing wall 34 is arranged on the lower bottom surface of the pressing block 33, and a second arc-shaped notch matched with the outer peripheral surface of the eccentric shaft 5 is formed in the pressing wall 34. Preferably, the first arc-shaped notch 131 and the second arc-shaped notch in this embodiment are respectively closely attached to the outer peripheral surface of the eccentric shaft 5, and during clamping, the eccentric shaft 5 can be placed in the first arc-shaped notch 131 first, and then the screw 31 is adjusted, so that the eccentric shaft 5 is tightly pressed by the second arc-shaped notch. Preferably, the screw 31 in this embodiment is screwed to the beam of the gantry 2, and the two side walls of the gantry are fastened to the two ends of the slide rail, respectively.
