Circular conveying device of fixture

Abstract

The invention relates to a circular conveying device of a fixture, which has the characteristics of accurate motion, convenience in control, high working efficiency, simple structure and long service life. The technical scheme is that the circular conveying device of the fixture comprises an upper guide rail, a lower guide rail, fixture transfer mechanisms and a controller, and is characterized in that the fixture transfer mechanisms at two ends of the guide rails comprise rotary frames driven by rotary cylinders, and two pairs of cross rails which move along with the rotary frames so as to connect a fixture with the upper guide rail and the lower guide rail simultaneously, and two ends of the upper guide rail and the lower guide rail are respectively provided with a sensor used for monitoring whether the fixture enters or goes out of the cross rails or not; a fixture pushing cylinder for pushing the fixture in the cross rails into the upper guide rail is also arranged in the fixture transfer mechanism positioned at the start ends of the guide rails, and a chain mechanism for pushing the fixture on the cross rails of the fixture transfer mechanism at the tail ends of the guide rails into the lower guide rail and driving the fixture to move along the lower guide rail so as to make the fixture enter the cross rails of the fixture transfer mechanism at the start ends of the guide rails is also arranged.

Description

technical field [0001] The invention relates to a conveying device, in particular to a clamp straight-line running circular conveying device adopted on an industrial automatic assembly machine. Background technique [0002] Automatic assembly processing machine is a production mode commonly used in enterprises; especially when producing and assembling large quantities of fixed single products, it is a must-have production equipment; for the current difficulty in recruiting assembly workers, automatic assembly is used for manual production processes Substituting machining can save a large number of assembly workers, ensure product quality, and improve production efficiency, which has an immeasurable effect. [0003] The fixture circulation conveying device is the main structure of the automatic assembly machine. The product parts are loaded into the fixtures in the device one by one at the starting end of the fixture circulation conveying device, and are conveyed forward by ...

AI Technical Summary

Problems solved by technology

The structure of the chain conveying device is that the chain is driven by the sprocket, and the chain drags the fixture to move along the guide rail; the advantage of this device is that the structure is simple, but the positioning of the fixture in the forward direction is difficult to control, and it is difficult to ensure that each processing Work station processing quality

The characteristic of the parallel guide rail plus elevator conversion device is to rely on the vertical transport mechanism at the starting end to transfer the fixture of the lower guide rail to the upper guide rail, and the vertical transport mechanism at the terminal to transfer the fixture of the upper guide rail to the lower guide rail; this kind of device also faces The positioning of the fixture in the forward direction is difficult to control, and the production efficiency is not high, the mechanism is more complicated, and the control is more difficult
