The workpiece body 30 can be fixed by cooperating with the movable clamping member 140 , thereby preventing the workpiece body 30 from shifting when the turntable 120 rotates, thereby preventing errors in detection.
[0029] In this embodiment, each movable clamping member 140 includes a handwheel 141 fixedly connected to a threaded rod 142. Each threaded rod 142 is threadedly connected in a circular array through the workpiece placement platform 130 and rotatably connected to a connecting seat, which is removably connected to a clamping plate 143. The side wall of the workpiece placement platform 130 is provided with a clearance groove 170 that cooperates with the clamping plate 143. The cooperation between the handwheel 141, the threaded rod 142, and the clamping plate 143 enables the clamping of workpiece bodies 30 of various specifications, thereby expanding the applicability of the device.
[0030] In a specific configuration, the clamping plate 143 and the connecting seat are both provided with connecting bolts 160. The clamping plate 143 has a countersunk hole, and the nut of the connecting bolt 160 is located within the countersunk hole.
