Embodiment

As illustrated, a kind of polygon movement at the uniform velocity device described in the utility model embodiment, including：As shown in Figure 1, Figure 2 Shown, conveyer belt 1 drives conveying of turning left by intermittent motion mechanism, locating ring 2 is equidistantly provided with conveyer belt 1, workpiece 3 is put It is placed in locating ring 2, the thickness of workpiece 3 is consistent with locating ring 2；Processing stations 4 are located on the left of device, and profile modeling rail 5 is fixed In the center of processing stations 4, top, the shape of profile modeling rail 5 is consistent with workpiece 3；Synchronous pulley 6 is arranged on profile modeling rail 5 Center at, as shown in fig. 6, angle of circumference is divided into three sections by synchronous pulley 6, respectively extension diameter section 61, steady section 62, retraction section 63, the radius of extension diameter section 61 becomes larger, and changing value is corresponding with the leading portion 151 of Operation trochoid 15, the radius value of steady section 62 Constant, radius value is corresponding with ring segment 152, and the radius of retraction section 63 tapers into, the back segment of changing value and Operation trochoid 15 It is corresponding, as shown in figure 1, synchronous pulley 6 is circumscribed with timing belt 7；Turning arm 8 is connected by key with synchronous pulley 6, as shown in figure 3, Long gain 81, guide plate 9 are fixed on the both sides of long gain 81, the end of turning arm 8 to the upper processing along its length of turning arm 8 together Spring nail 11 is installed；Sliding block 12 is arranged between guide plate 9 and passes through spring 10 and the elastic connection of spring nail 11；Such as Fig. 4 institutes Show, processing head 13 is arranged on the lower section of sliding block 12, and processing head 13 through long gain 81 and is furnished with rolling bearing 14 in lower end, rolls The bearing top circle of bearing 14 is adjacent on the inwall 51 of profile modeling rail 5 all the time under the resilient force of spring 10.
