Description

The punch press clutch

The utility model relates to mechanical clutch means, a kind of specifically punch press clutch.

Often need moment to stop during punch press work, so that carrying out station changes or workpiece loading and unloading, the interruption of its transmission and joint are realized by clutch, the sensitivity of arrangement of clutch not only influences working (machining) efficiency, the safety that also is related to operation, the general use of existing punch press clutch rolled key and horizontal slotting key, rolls the active force of key and concentrates inadequately, horizontal slotting key is not durable, and repairs and change difficulty.

The purpose of this utility model is the deficiency that overcomes prior art, and a kind of punch press clutch is provided, and reaches force localization, and clutch is clear, the purpose of durable, easy repairing.

The purpose of this utility model is achieved in that

A kind of punch press clutch is installed between punch press transmission flywheel and the bent axle, and by foot pedal apparatus control, the transmission realization clutch to transmission flywheel and bent axle is characterized in that its structure comprises:

One clutch main body, being has the ladder of centre bore cylindrical, and its centre bore is with key and bent axle secure fit, the oblique gap that one bending is arranged on its big end external cylindrical surface, its bending post jamb and small end cylinder join, and respectively there is an axis hole radially at two ends, this gap bottom, are shaped on a spring eye on the bending post jamb;

One clutch taper key is made of the plate body and the rotating shaft of disjunctor, and this plate body is convexly curved, and this arcwall face is the Y font, and hooked projection is arranged at its top, and its rotating shaft is vertically stretched out to two ends from the plate body lower edge, is provided with a recessed locating hole in appropriate location, plate body side;

One clutch lever, long-armed, galianconism and rotating shaft by the disjunctor bending constitute, long-armed top has the collision block of arc head and foot-operated linkage corresponding, and it is hook-shaped corresponding with the hooked projection clutch taper key that galianconism is the arc head, and its rotating shaft is vertically stretched out to two ends from junction long-armed, galianconism;

One gland is installed on the upper end of the big end external cylindrical surface gap of clutch main body with screw, and this gland has two axis holes to align mutually with two axis holes of clutch main body respectively;

The rotating shaft of described clutch taper key and clutch lever is loaded on respectively in the axis hole of clutch main body and gland, and the hooked projection of clutch taper key is relative with the position of clutch lever galianconism, and can be stirred by galianconism;

With dog screw the compression spring is housed in the spring eye of the bending post jamb of clutch main body, this spring stretches in the location hole of the spring on the plate body side of clutch taper key;

Described clutch taper key heads under spring action in the corresponding wedge shape keyway of transmission flywheel.

The top of the wedge shape keyway of described transmission flywheel fixedly is embedded with the collision post that stiff materials is made.

The quantity of the wedge shape keyway on the described transmission flywheel is 1-4.

The utility model has following actively useful effect:

1, force localization: the top that the transmission flywheel promotes the clutch taper key with the collision post in the skewed slot, the clutch taper key promotes the clutch main body by transverse axis, thereby power is passed to bent axle, and its gearing power is concentrated.

2, clutch sensitivity: use lever principle, clutch lever long-armed is subjected to the collision block of foot-operated linkage to hit to touch upwards to lift, its galianconism acts on the hooked projection of clutch taper key and uses this taper key outwards to rotate, the skewed slot that breaks away from the transmission flywheel, the taper key transmission is interrupted, and makes the transmission flywheel in crankshaft end idle running and bent axle stops operating.

3, reliable transmission: the rotating shaft of clutch taper key and taper key top stress point be not in same plane, and the stressed back of taper key tilts to the direction of applying transmission flywheel wedge shape keyway, and pressure is big more, and in conjunction with firm more, transmission is reliable more.

4, perpendicular solid durable: the top at the wedge shape keyway of cast iron transmission flywheel is embedded with the Impactor that perpendicular hard material is made, wear-resisting anti-going out, the service life of having improved a whole set of clutch.

5, maintenance easily: the clutch main body is that screw is connected with gland, pulls down gland and gets final product convenient for maintaining, changes clutch taper key and clutch lever, and the Impactor in the transmission flywheel also connects for screw, thereby mounting or dismounting are simple, and maintenance easily.

6, structure of the present utility model also can be used for the machinery that other has the clutch transmission.

Now in conjunction with the accompanying drawings with preferred embodiment:

Fig. 1 is a structural representation of the present utility model, is the transmission bonding station.
