Description

Coupling for punch press Technical Field The utility model belongs to the technical field of couplings, and particularly relates to a coupling for a punch. Background In modern industrial systems, the press is used as a key press working device, and plays an irreplaceable role in a plurality of fields such as automobile manufacturing, electronic equipment production, hardware processing and the like. In the automobile manufacturing process, various complex-shaped automobile body parts are punched accurately by a punching machine, in the production of electronic equipment, high-precision molding of small-sized metal parts is guaranteed by accurate punching operation, and the punching machine is core equipment for efficiently producing a large number of standard parts in the hardware processing industry. When the punching machine works, the power source (such as a motor) is required to stably and efficiently transmit power to key working parts such as a crankshaft and the like by virtue of a coupling, so that the sliding block is driven to finish the punching operation on materials such as plates and the like. This process requires excellent performance of the coupling, and can ensure stable operation of the punch press and high precision of the punching process. Currently, crowned tooth couplings, oldham coupling and the like are commonly used in the field of punching machines. The impact property is strong and the vibration is severe when the punch press works, and the severe working condition provides a severe challenge for the used coupler. The existing coupling is difficult to effectively buffer and damp, so that the overall stability of equipment is greatly reduced, the stamping precision is difficult to ensure, equipment faults are frequently caused, the maintenance cost and the downtime are increased, and the production efficiency and the economic benefits of enterprises are severely restricted. Therefore, it is necessary to provide a coupling for a punch press. Disclosure of utility model In order to solve the technical problems, the utility model provides a shaft coupling for a punch press, which comprises a butting disc, grooves, connecting discs, protruding teeth, a clamping sleeve table, a spline sleeve, spline pads, a shaft coupling disc, spline grooves, shaft sleeves and fastening bolts, wherein the two grooves are respectively matched with the protruding teeth integrally arranged on the corresponding connecting discs on the surface of the butting disc, the spline sleeve is sleeved on the outer surface of the clamping sleeve table integrally arranged on the other side surface of each connecting disc, the spline pads are fixedly adhered to the end surfaces of the clamping sleeve table, the spline sleeves and the spline pads are clamped in the spline grooves of the shaft coupling disc, and the shaft sleeves integrally arranged on the shaft coupling disc are assembled with the corresponding shaft body in a parallel key manner and are fixedly installed together through the fastening bolts. Preferably, grooves formed in two surfaces of the abutting disc are perpendicular to each other, and each groove is embedded with a tooth corresponding to the abutting disc. Preferably, the diameters of the butt joint disc, the connecting disc and the coupling disc are the same, the butt joint disc is positioned between the two connecting discs, and protruding teeth and the clamping sleeve table are integrally arranged on the surfaces of the two sides of the connecting discs respectively.
