Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1 and 2, the utility model provides a workpiece positioning carrier, including a bottom plate 1, a first positioning layer 2 and a second positioning layer 3 are arranged on the bottom plate 1, a cavity 4 is arranged on the second positioning layer 3, the cavity 4 is a profiling cavity arranged according to the outer wall of a product, the product can be clamped in the cavity 4, a jacking mechanism is arranged on the lower part of the bottom plate 1, the structure of the jacking mechanism comprises a jacking cylinder 6, the output end of the jacking cylinder 6 is connected with a top plate 8, two groups of ejector rods 9 are arranged on the top plate 8, an inclined plane 10 is arranged on the top of the ejector rods 9, the jacking cylinder 6 extends upwards to drive the two groups of ejector rods 9 on the top plate 8 upwards, two groups of pressing mechanisms 5 are embedded in the first positioning layer 2, and the pressing mechanisms 5 extend to the side wall of the cavity 4 of the second positioning layer 3; the jacking mechanism pushes the pressing mechanism 5, and the ejector rod 9 pushes the pressing mechanism 5 to press the product to the upper stage.

Specifically speaking, hold-down mechanism 5 includes stopper 18, push rod 19 has passed in the stopper 18, push rod 19 with be equipped with round pin 12 between the stopper 18, be equipped with a set of or two sets of pressure head 13 on the push rod 19, the lower part is equipped with gyro wheel 14, gyro wheel 14 press in on the inclined plane 10, when inclined plane 10 upwards promoted, gyro wheel 14 rolls along inclined plane 10 to make push rod 19 rotate along round pin 12, make push rod 19 open to both sides, be convenient for place the product, second location layer 3 center is equipped with spacing ring 7, spacing ring 7 lateral wall has inlayed two sets of sensors 11, places the back on spacing ring 7 when the product, and sensor 11 senses the product and targets in place, then starts the shrink of jacking cylinder 6, makes gyro wheel 14 slide along inclined plane 10 for push rod 19 realizes vertical state.
