[0017] Such as Figures 1-3As shown, a pneumatic loading and unloading mechanism of a diaphragm chuck includes a diaphragm chuck 1, a clamping cylinder 2, a rotating mechanism, a loading mechanism, a unloading mechanism, and a base 3; the loading mechanism includes a material trough 4, a pushing cylinder 5, a feeding cylinder 6, a bracket 7, and a loading positioning plate 8. The bracket 7 is arranged on the base 3, and the bracket 7 is provided with a material trough 4, a pushing cylinder 5, a feeding cylinder 6, and a loading positioning plate 8. The material trough 4 is vertically arranged on the side of the clamping surface of the diaphragm chuck 1, and the end of the material trough 4 forms a pushing station, which is flush with the center of the diaphragm chuck 1, and the output end of the pushing cylinder 5 is aligned with the center of the diaphragm chuck 1. The pushing station is aligned, the moving trajectory of the output end of the pushing cylinder 5 forms the radial part of the feeding channel, the output end of the feeding cylinder 6 is aligned with the center of the diaphragm chuck 1, and the moving trajectory of the output end of the feeding cylinder 6 forms the axial part of the feeding channel. The material trough 4, the pushing cylinder 5, and the feeding cylinder 6 form a vertical-radial-axial continuous feeding channel; a positioning groove 9 is provided on the feeding positioning plate 8, and the positioning groove 9 is aligned with the center of the diaphragm chuck 1. The positioning groove 9 cooperates with the output end of the feeding cylinder 6 to position the workpiece for feeding, ensuring that the center of the workpiece is aligned with the center of the diaphragm chuck 1.

[0018] The rotating mechanism includes a motor 10 and a workpiece shaft 11. The motor 10 and the workpiece shaft 11 are arranged on a base 3. The motor 10 and the workpiece shaft 11 are connected by a transmission belt mechanism. The workpiece shaft 11 is connected to the clamping cylinder 2.
