Patent ID: 7117713

Claim:
A terminal crimping machine, comprising: a base body provided at a lower end thereof with a feeding platform for placing terminal-chain thereon; a punching mechanism having an upper crimper and a driving piece; an adjusting mechanism provided with a fixing block and an adjusting screw, the fixing block fixed on the base body and the adjusting screw adjustably disposed on the fixing block; an auto-feeder having a fixing base disposed on a front side of the base body, and a first driven piece and a second driven piece disposed in the fixing base in an interlocking manner, wherein the second driven piece is driven by an elastic force of an elastic element to abut against the adjusting screw of the adjusting mechanism, and the second driven piece is provided at an end thereof with a pushing block, the driving piece of the punching mechanism is employed to drive the first driven piece, so as to enable the second driven piece to push terminals on the base body; in crimping operation, by adjusting the adjusting screw of the adjusting mechanism, a distance between the pushing block of the second driven piece and the upper crimper can be adjusted to fit different sized terminals, enabling the auto feeder to push the different sized terminals to a crimping position for crimping operation; a protrusive block is provided on the feeding platform, an elastic block is formed on the protrusive block for enabling terminals to be conveyed smoothly; the fixing base of the auto-feeder is provided with a first groove and a second groove in a lateral direction thereof, and a space is defined between the first and the second grooves, a recess is formed in a bottom of the first and the second grooves, respectively, for reception of the elastic element, the first and the second driven pieces are provided with protrusive bars at a side thereof, and the first and the second driven pieces are received in the first and the second grooves respectively in a manner that the protrusive bars abut against an end of the elastic element, a gear cluster is disposed in the space of the fixing base for meshing with the first and the second driven pieces, so that the first and the second driven pieces can move synchronously.
