Riveting machine for riveting circuit board

Abstract

The invention discloses a riveting machine for riveting a circuit board. The riveting machine structurally comprises a control console, a telescopic rod, a motor, a pressing needle, an ejector pin and a base, the control console is electrically connected with the motor, the telescopic rod is connected to the bottom of the control console, the pressing needle is arranged on the telescopic rod, and the pressing needle and the ejector pin are indirectly matched together; and the pressing needle comprises a pressing disc, a connecting block, a spring, a connecting rod and an opening and closing buckle, the connecting block is connected between the telescopic rod and the connecting rod, the connecting rod is connected with the spring, a pressing disc is connected to the bottom of the connecting rod, and the opening and closing buckle is installed on the pressing disc. A pressure collecting assembly and a stable splicing device are arranged in a boost mechanism, in the pressing process of the bottom of a rivet, a clamping piece and a warping hook are mutually screwed, so that the pressure collecting assembly reversely shifts on the two faces of the stable splicing device and abuts against a hook of the stable splicing device, the friction force between the stable splicing device 553 and a round cap of the ejector pin is increased, and the stable splicing device 553 is prevented from slipping on the round cap of the ejector pin.

Description

technical field [0001] The invention relates to the field of riveting machines, in particular to a riveting machine used for riveting circuit boards. Background technique [0002] As a common fixed connection method in mechanical processing, rivet connection has the advantages of low cost and high connection fastness. The existing rivet connection usually uses manual methods to place the rivet at a predetermined position and then uses special equipment for stamping and riveting. On the one hand, this method increases the labor intensity of the operator, affects work efficiency, poor precision, and there are certain safety hazards in safe operation; the existing riveting machines for circuit board riveting generally ensure that the bottom of the rivet can be completely riveted On the circuit board, the opening and closing buckle of the pressing nail has the same diameter as the top of the round cap of the thimble. When the pressing pin vertically presses to cover the top of t...

Problems solved by technology

On the one hand, this method increases the labor intensity of the operator, affects work efficiency, poor precision, and there are certain safety hazards in safe operation; the existing riveting machines for circuit board riveting generally ensure that the bottom of the rivet can be completely riveted On the circuit board, the opening and closing buckle of the pressing nail has the same diameter as the top of the round cap of the thimble. When the pressing pin vertically presses to cover the top of the round cap of the thimble, its opening and closing buckle will open on the round cap, because the top of the round cap The surface is very smooth, so that the bottom of the rivet will be riveted unstable during the pressing process, so that it is difficult for the press needle to simultaneously curl the bottom of the rivet, resulting in uneven warping and deformation of the bottom of the rivet, and cannot be completely riveted on the circuit board, and even affect the finished quality of the circuit board around the riveting hole
