Description

Technical Field

[0001] The utility model belongs to the technical field of bolt production, and in particular relates to an automatic assembly machine for bolts and nuts. Background Art

[0002] A bolt consists of a head and a shank, which must be mated with a nut to secure parts together. This type of connection is called a bolted connection. Removing the nut from the bolt allows the two parts to separate, making a bolted connection removable. After production, the nut is typically screwed onto the bolt to facilitate storage and shipment, minimizing the number of parts lost. Currently, bolt and nut assembly is typically performed manually, which can cause finger pain after a period of work, impacting both worker health and significantly reducing assembly efficiency. Utility Model Content

The upper end of the first clamping block is symmetrically fixed with a first connecting block, and the upper end of the second clamping block is symmetrically fixed with a second connecting block, and the positions of the first connecting block and the second connecting block correspond to each other. A second hydraulic rod mechanism is fixedly provided horizontally between the first connecting block and the second connecting block, which not only ensures the stability and reliability of the position of the second clamping block, but also facilitates the second clamping block to move horizontally smoothly, thereby reliably abutting against the first clamping block to tightly clamp the nut.

[0006] A first clamping groove is horizontally opened on one side of the first clamping block close to the second clamping block, and a second clamping groove is horizontally opened on one side of the second clamping block close to the first clamping block. The positions of the first clamping groove and the second clamping groove correspond to each other and are the same in size. The first clamping groove is located directly above the hexagonal groove.
