Comprehensive experiment table of cam

The invention discloses a comprehensive experiment table of a cam, and belongs to the field of mechanical experiment teaching. The comprehensive experiment table comprises a rack, a guide rail, a supporting plate, a gear, a rack, a step motor, a worm, a worm gear, a synchronous pulley A, a synchronous pulley B, the cam, a workpiece and a polished rod II, wherein the connection relation of the components is that the guide rail and the rack are fixedly arranged on the lower surface of the rack in parallel, the supporting plate is connected with the guide rail in a sliding manner, the step motor A is fixedly arranged on the supporting plate, the step motor rotates to drive the worm to rotate, the worm is engaged with the worm gear, the worm gear rotates around a fixed axis so as to drive the gear, the synchronous pulley A, a chip receiving tray and the workpiece on the shaft to rotate together, the gear is engaged with the rack to further drive all the components on the supporting plate and the polished rod II to move along the guide rail, the rotation of the synchronous pulley A is transferred to the synchronous pulley B through a synchronous belt, and the synchronous pulley B drives the cam to rotate coaxially. The comprehensive experiment table is a cam teaching aid, and can realize evolution of an overall process from design to machining of the cam and a cam machining method.
