に記載の自動ねじ締め機。[Claims for Utility Model Registration] 1. A driver stand that is raised and lowered by the operation of an elevating drive source is provided, a motor is fixed to this driver stand so as to move up and down integrally, and the rotation of the drive shaft of this motor is transmitted through a transmission mechanism. The screw is transmitted to the driver bit and is supplied to a predetermined position as the driver base is lowered, and is configured to tighten the screw to the workpiece.
In an automatic screw tightening machine equipped with a sensitive part that is affected by the surrounding temperature, a cylindrical bracket is installed close to the sensitive part,
An air supply hole through which air is supplied from the air supply source is bored in this bracket, and a plurality of air injection holes through which air from the air supply hole is injected are formed in this bracket. An automatic screw tightening machine characterized by having its tip located on the outer periphery of the sensing part. 2. A driver stand that moves up and down by the operation of the lifting drive source is provided, and a gear case filled with lubricating oil is placed on the driver stand so as to move together with the driver stand,
While the motor is fixed to this gear case, inside the gear case there is an input disk rotated by the rotational drive of the motor, a plurality of planetary cones having circumferential grooves that frictionally engage with the outer periphery of the input disk, and a back surface of the planetary cone. A cam disc that is frictionally engaged is arranged, and a speed change ring that is frictionally engaged along the conical surface of the planetary cone is rotatably arranged, and this is held by an arm that has one end locked on the driver stand side. The automatic transmission is configured by holding the transmission ring and biasing it toward a high speed side via a spring, and furthermore, an output shaft is connected to the cam disk, and a driver bit is connected to the output shaft so as to rotate integrally with the output shaft. In a connected automatic screw tightening machine, a bracket having a protruding part that protrudes outward from the gear case is connected between the gear case and the motor, and the drive shaft of the motor and the input disk are connected via a coupling tool. On the other hand, an air supply hole is formed in the bracket through which air is supplied from an air supply source, and a plurality of air injection holes are formed in the protrusion of the bracket to inject air from the air supply hole. This automatic screw tightening machine is characterized in that the tip of this air injection hole is located on the outer periphery of the gear case. 3. Claim 2, characterized in that the gear case is provided with a plurality of protrusions on the outer periphery to increase the outer periphery surface area.
Automatic screw tightening machine described in .
