Abstract

The invention discloses a riveting device and a riveting method. The riveting device comprises a material containing portion, a riveting driving portion and a riveting assembly. The material containing portion is used for containing a first assembly, and the riveting driving portion can enable the riveting assembly to move towards or away from the material containing portion. The riveting assembly comprises a pressing part and a riveting head, the pressing part comprises a hole portion, one end of the riveting head extends into a cavity of the hole portion, and the peripheral wall corresponding to the part, extending into the hole portion, of the riveting head is in clearance fit with the peripheral wall of the hole portion. When the riveting driving portion drives the riveting assembly to move towards the material containing portion, the lower surface of the pressing part can make contact with the upper surface of a second part located on the material containing portion, and the pressing part can apply pressure to the second part located on the material containing portion. When the lower surface of the pressing part makes contact with the upper surface of the second part located on the material containing portion, the riveting head can continue to move downwards. When the riveting head continues to move downwards to a first preset position, the riveting head can rivet the connecting portion of a first part. The riveting device and the riveting method are beneficial to improving the riveting reliability of parts.

Description

technical field [0001] The present application relates to the field of mechanical equipment, in particular to a riveting device and a riveting method. Background technique [0002] The one-way valve is mainly used to prevent the reverse flow of the fluid, which is widely used in the refrigeration system; the one-way valve includes the valve core part, the valve core part includes the valve core and the parts sleeved on the outer periphery of the valve core, and the sleeve is made by riveting. The components on the outer periphery of the valve core are fixedly connected to the valve core; however, in the actual riveting process, it may be encountered that the operator fails to place at least one component sleeved on the outer circumference of the valve core in place and / or sets it on the The surface of at least one part on the outer periphery of the valve core has burrs, etc., which may affect the reliability of riveting. Therefore, when the above situation is encountered, ho...
