Abstract

A fastening tool (20) is provided with a housing (22) having a fastener outlet (28). A striker (30) is mounted for translation in the housing to drive a fastener from the fastener outlet in an unloaded position. A biasing member (34) cooperates with the striker to urge the striker towards the unloaded position. A motor (38) is oriented in the housing. A cam (42) is driven by the motor, and has a cam surface (44) in cooperation with the striker such that rotation of the cam translates the striker to a loaded position and to a release position whereby the biasing member drives the striker to the unloaded position. The cam surface is profiled to require a constant torque from the rotary input during translation of the striker to the loaded position while loading the biasing member.

Description

technical field [0001] Various embodiments relate to motor driven fastening tools. The invention discloses a fastening tool. Background technique [0002] Power fastening tools incorporate a variety of drive mechanisms. A fastening tool includes a solenoid driver that drives a blade that drives a fastener. Another type of fastening tool incorporates a motor-driven gearbox with an eccentric drive that lifts and subsequently releases a plunger against a spring, wherein the spring drives both the plunger and the attached blade that drives the fastener . Another type of fastening tool consists of a motor-driven gearbox that drives a connecting rod to compress air in a cylinder. The compressed air is then released into a smaller cylinder, driving the blades, which drive the fasteners. Another fastening tool contains a battery to power the device that ignites the air-fuel mixture through rapid expansion of the mixture within the cylinder to drive the plunger and drive the fas...
