3.2.3 Clutch

The typical time for the torque application during assembly of a screw connection is shown in illustration 4.

illustration 4: Torque time diagram (screw/nut with metric thread)

After being positioned the screw (or the nut) is first screwed into the thread. This usually only requires the application of limited torque. The tightening torque increases as soon as the fastener rests on the joint component. When the preset tightening torque MA is reached the WEBER manual assembling device is switched off by the clutch. 3.2.4 Friction clutch

If a friction clutch is used, the screwing sequence ends as soon as the set screw-in torque is reached: 󰂃 󰂃 󰂃

the peripheral force exceeds the initial spring tension,

there is no friction for a brief moment between the clutch disks, the screwdriver bit is separated from the power drive.

The transmittable peripheral force can be set with the spring washer’s initial tension. Suitable pre-determined clutch disks are installed ex works for differing torque ranges (see spare parts list). 3.2.5 One-shot clutch

If a one-shot clutch is used, the screwing sequence ends as soon as the set screw-in torque is reached: 󰂃 󰂃 󰂃

the peripheral force exceeds the initial spring tension,

there is no friction for a brief moment because the balls are pushed out of their nests, the screwdriver bit is separated from the power drive.

The transmittable peripheral force on the ball nests can be set with the spring washer’s initial tension. Suitable pre-determined clutch disks are installed ex works for differing torque ranges (see spare parts list).

4.2 Description of the assembling sequence

󰂃

Fill the feed unit bowl with fastening elements. 󰂃 󰂃

The fastening elements travel up the spiral in the bowl (micro throw principle).

The orientation equipment built into the bowl aligns the fastening elements being transported.

Correctly aligned parts reach the exit track in a row; wrongly aligned parts fall back into the bowl and are then transported again. The escapement is in lead-in position.

The first screw is shoved into the escapement inlet by the bottle-neck pressure of the following fastenings. (The shape of the inlet can be modified accordingly)

A fastening element is in the mouth piece of the hand-held screwdriver; the screwdriver bit is in home position. Guide the hand-held screwdriver to the position in which it is to be used. Actuate the trigger bar on the hand-held screwdriver. 󰂃

󰂃

The screwing sequence starts again.

The screwing sequence commences!

The screwdriver sinks (without rotating) onto the screw head; the bit slots into the feature where the force is applied on the fastening element.

The fastening element is pushed through the mouth piece.

The pressure against the screwdriver closes an open engaging clutch. The screwdriver bit and the screw begin to turn.

The segments of the mouth piece open when the screw head is pushed through. The screwdriver leaves the mouth piece.

The fastening element is screwed into the workpiece; screws which are not screwed in are ejected. The clutch shut off when the pre-set torque is reached. The drive switches off. The screwdriver moves back.

The escapement moves into lead-in position.

The escapement takes a fastening element from the flow of parts. This falls down into the feed tube.

After a free-fall of approx. 100 mm it is shot through the feed tube by a blast of compressed air (suction air in the case of very small fastening elements).

The fastening element falls into the screwdriver’s mouth piece.

Release the trigger bar!

Actuate the trigger bar on the hand-held screwdriver!
