PROBLEM TO BE SOLVED: To pass and convey a work by a single drive mechanism with a simple structure.SOLUTION: A work conveying device 1 can convey a first work support part 3 and a second work support part 4 having receiving parts 9A, 9B for supporting works W between a replacement position A and a machining position B. A first cam groove 5 and a second cam groove 6 for guiding conveyance of the first and second work support parts 3, 4 are arranged on a substrate 2. The first cam groove 5 includes a front part first cam groove 5a and a rear part first cam groove 5b, and the second cam groove 6 includes a front part cam groove 6a and a rear part second cam groove 6b separately. A pinion 14 is arranged in between. By swinging and reciprocating the first work support part 3 by a hydraulic cylinder 32, respective racks 11a, 11b of the first and second work support parts 3, 4 travel in opposite directions between the replacement position and the machining position through the pinion 14. As curve parts curving outward are formed on the rear part first and second cam grooves 5b, 6b, both of the receiving parts 9A, 9B do not interfere with each other in passing. |
