Automatic riveting nut equipment for plastic shell cover

Abstract

The invention discloses a piece of equipment used for automatically riveting a nut on a plastic shell cover. The equipment is characterized in that the equipment comprises a rack, a nut supply mechanism, a nut locating mechanism, a nut conveying mechanism, an assembly mechanism and a compressing mechanism, a station switching mechanism is fixedly arranged on a horizontal working platform of the rack and comprises a station base, a horizontal guide rail, a station slide carriage and a switching cylinder, the nut supply mechanism comprises a nut vibration disc and two feeding rail grooves, the nut locating mechanism comprises a nut locating frame and two nut locating check blocks, the nut conveying mechanism comprises a bracket, a longitudinal guide rail, a longitudinal slide carriage, a longitudinal cylinder, a vertical cylinder, a connecting plate and two nut clamping claws, the assembly mechanism comprises a rotating cylinder, a vertical rotating shaft, a lower support disc, an uppersupport disc, a plastic shell cover locating disc, a nut locating rod and a reset elastic piece, and the compressing mechanism comprises a compressing bracket, a vertical slide rail, a lifting base, apressing head and a compressing cylinder. The equipment can automatically rivet the nut on the plastic shell cover.

Description

technical field [0001] The invention belongs to riveting equipment, in particular to an automatic riveting nut equipment for plastic shell covers. Background technique [0002] Existing injection molds are used to produce plastic products, especially products with threads (mainly referring to internal threads). The core-pulling rotation speed and axial displacement are synchronized and uniform, and the two movements are uniform and stable, so the qualified rate of the produced products is low. Therefore, it is necessary to assemble the plastic parts by nut riveting to replace the mold processing internal threads on the injection molding machine. [0003] And in existing nut riveting assembly, can refer to figure 1 , if it is necessary to rivet four nuts (M) in the four nut sink holes (N-1) on the inner surface of a plastic shell cover (N), the four nut sink holes (N-1) are along the circumferential direction Evenly distributed; in the existing production, only manual rive...

Problems solved by technology

[0003] And in existing nut riveting assembly, can refer to figure 1 , if it is necessary to rivet four nuts (M) in the four nut sink holes (N-1) on the inner surface of a plastic shell cover (N), the four nut sink holes (N-1) are along the circumferential direction Evenly distributed; in the existing production, only manual riveting one by one, there are problems such as low production efficiency, high labor intensity, unstable product quality, etc.
