It solves the technical problems of low assembly efficiency of large chains, low efficiency of manual assembly, inability to guarantee chain quality, and inability to meet higher production demands in the existing technology.

[0004] The above-mentioned technical problem of this utility model is solved by the following technical solution: A chain assembly riveting device includes a machine base with an assembly groove on its surface. The left end of the machine base is the feeding end, and the right end is the discharging end. An assembly mechanism is provided at the left end of the machine base, where the lower chain piece, small tube, sleeve, upper chain piece, pin, lower connecting piece, and upper connecting piece are assembled into a complete chain. A riveting mechanism is provided at the right end of the machine base, and a drive mechanism for moving the chain is also provided at the right end of the machine base. During processing, the lower chain piece, small tube, sleeve, upper chain piece, pin, lower connecting piece, and upper connecting piece fall into the assembly groove and are assembled into a complete chain by the assembly mechanism. After the chain is assembled, the riveting mechanism performs riveting processing on the chain. The riveting mechanism presses the chain riveting head, and while the riveting head is being processed, the drive mechanism drives the chain to move and discharge.

[0005] Preferably, the riveting mechanism includes a four-corner riveting machine mounted above the assembly slot, with several pressure plates spaced apart on the machine. During processing, the lower chain plate, small tube, sleeve, upper chain plate, pin, lower connecting plate, and upper connecting plate fall into the assembly slot and are assembled into a complete chain by the assembly mechanism. After the chain is assembled, the riveting mechanism performs riveting, with the pressure plates reciprocating to press the chain riveting heads together.

[0006] Preferably, the riveting machine includes pressure rollers mounted on the upper and lower sides of the assembly slot, which press against the upper and lower surfaces of the chain. The pressure rollers are driven by a motor. After the chain is assembled, the riveting mechanism performs riveting.

While the riveting head is being processed, the drive gear rotates at intervals to move the chain and discharge the material.

[0007] Preferably, the drive mechanism includes a drive gear rotatably mounted on the right side of the machine base. A notch is provided on one side of the assembly slot, and the drive gear meshes with the chain at the notch. After the chain is assembled, it undergoes riveting by a riveting mechanism. The pressure plate reciprocates to press the chain riveting head tight. While the riveting head is being processed, the drive gear rotates intermittently to move the chain and discharge the material.

[0008] Preferably, the drive mechanism further includes a drive telescopic rod slidably mounted on the front side of the machine tool, with a ratchet rotatably mounted at the end of the drive telescopic rod, the ratchet engaging with the drive gear. The drive telescopic rod drives the ratchet to move laterally reciprocally, and the ratchet drives the drive gear to rotate intermittently.

[0009] Preferably, the bottom end of the drive gear is fixed with a rotating shaft, and the surface of the rotating shaft is provided with grooves spaced apart, in which the ratchet teeth are engaged. During the processing, the drive telescopic rod reciprocates laterally, and the ratchet teeth at the end of the drive telescopic rod drive the drive gear to rotate a fixed angle once, thereby driving the chain to move and discharge the material.

[0010] Preferably, the drive telescopic rod has an "L" shaped structure.

[0011] Preferably, the drive mechanism further includes a drive motor fixed to one side of the machine base and a sliding sleeve sleeved over the drive telescopic rod, with the drive telescopic rod mounted on the drive motor. The drive telescopic rod moves laterally reciprocating within the sliding sleeve, driving the drive gear to rotate.

[0012] Preferably, both the sliding sleeve and the drive telescopic rod are provided with positioning blocks, and a return spring is provided between the positioning blocks. The function of the return spring is to provide assistance when the drive telescopic rod extends or retracts.

[0013] Therefore, the chain assembly riveting device of this utility model has the following advantages: high automated production efficiency, ensuring high connection strength of parts after chain assembly, applicable to the assembly of various irregular chains, greatly reducing the need for manual work, and meeting higher production requirements.
