Abstract

The utility model discloses a filament winding main shaft device applied to a filament winding machine. The filament winding main shaft device includes a motor I and a filament winding main shaft. The filament winding main shaft is provided with a sliding pusher which is provided with a boss on an end, a spring which is connected with the sliding pusher, a filament clamp with one end clinging to the boss of the sliding pusher, and a core rod which is locked on the sliding pusher. The sliding pusher is connected with a shift fork which can move horizontally from left to right. The shift fork is fixedly connected with a nut and is arranged on a horizontal screw via the nut. The screw is driven by a motor II. The input terminal of the motor II is connected with a control system. The filament winding main shaft device uses two motors to give power. One motor drives the filament winding main shaft to rotate, and the other motor drives the filament clamp to open or close and controls the expansion and contraction of the core rod, and uses the screw and the nut to restrain the rotation of the nut via a linear bearing, so the rotation motion of the motor is converted into the horizontal linear motion in which the shift fork is driven by the nut, and consequently the transmission path of the shift fork is shortened, and the transmission errors are reduced.

A kind of wrapping wire main shaft device that is applied on the spiral filament forming machine

Technical field

The utility model relates to a kind of centreless spiral filament forming machine, is specifically related to a kind of wrapping wire main shaft device that is applied on the spiral filament forming machine.

Background technology

Spiral filament forming machine is a machine of making coiled filament; Its course of work is: send into silk folder to tungsten filament and clamp, clamp back wrapping wire main axis rotation, cooperate moving horizontally tungsten filament by certain TPC value (number of turns of centimetre filament) requirement around to plug of tungsten filament; After the coiling, cut off tungsten filament and take out plug again.So the wrapping wire main shaft device is crucial in such spiral filament forming machine.Existing spiral filament forming machine utilizes cam link mechanism to lean on main motor power to realize the swing of shift fork, the slip hairclipper is moved reach silk with the swing of shift fork and presss from both sides an opening and closing movement and a plug expanding-contracting action.

The defective that this class formation exists is following:

1, complicated in mechanical structure, drive path is longer, must be through motor-main shaft-cam-connecting rod-shift fork.A series of gap errors (the especially long-term wearing and tearing back of using) accumulation back transmission accuracy is inevitable influenced, is unfavorable for accurate control;

2, swing shift fork its moment when stirring the slip hairclipper and move horizontally changes, and the lateral pressure that has increased parts makes that parts life-span shortens, mobile having some setbacks;

3, control the stroke of loosing core through the mode of adjustment length of connecting rod or adjustment stop screw, adjustment is inconvenient, and the mode of stop screw can produce very big noise and vibration;

Can not adjust the clamping force (can't reach the effect of fine setting by the mode of changing spring or change length of connecting rod) of silk folder, tiny tungsten filament clamped the phenomenon that occurs distortion, grain raising often.

Summary of the invention

In order to address the above problem, the utility model provides the wrapping wire main shaft device that mechanical structure is simple, easy to adjust, be more suitable for modern spiral filament forming machine application.
