Detailed Description

Referring to fig. 1-3, the transmission coupler for the bedplate of the elliptical printing machine comprises an upper spring steel plate 1, an inner bushing 2, an outer bushing 3, a left first retaining limiting plate 4, a left second retaining limiting plate 5, a right first retaining limiting plate 6, a right second retaining limiting plate 7, a lower spring steel plate 8, rivets 9 and an elliptical printing machine 14, wherein the left first retaining limiting plate 4, the left second retaining limiting plate 5 are sequentially fixed at the left end between the upper spring steel plate 1 and the lower spring steel plate 8 through the rivets 9, the right first retaining limiting plate 6 and the right second retaining limiting plate 7 are sequentially fixed at the right end between the upper spring steel plate 1 and the lower spring steel plate 8 through the rivets 9, a baffle 10 protruding upwards vertically is arranged at one end of each of the left first retaining limiting plate 4, the left second retaining limiting plate 5, the right first retaining limiting plate 6 and the right second retaining limiting plate 7, and baffles 10 arranged on the left first retaining limiting plate 4 and the right retaining limiting plate 6 respectively face upwards Plate 1, establish that the baffle 10 that left second kept limiting plate 5 and right second kept limiting plate 7 respectively towards lower spring steel plate 8, at last spring steel plate 1, left side first keeps limiting plate 4, left side second keeps limiting plate 5, the left end of lower spring steel plate 8 has all been seted up position and the unanimous left bush mounting hole 11 of size, at last spring steel plate 1, right side first keeps limiting plate 6, right side second keeps limiting plate 7, the right-hand member of lower spring steel plate 8 has all been seted up position and the unanimous right bush mounting hole 12 of size, at left bush mounting hole 11, respectively install an outer bush 3 through interference fit in the right bush mounting hole 12, closely inlay an interior bush 2 with solid glue respectively in two outer bushes 3. Gaps 13 are arranged between the left first retaining limiting plate 4 and the left second retaining limiting plate 5 and the right first retaining limiting plate 6 and the right second retaining limiting plate 7, and a bedplate track wheel shaft is arranged in the inner bushing 2. Go up spring plate, lower spring plate and left first keep limiting plate, left second keep limiting plate, right first keep limiting plate, right second keep limiting plate and rivet with the rivet and be in the same place, then reprocess left bush mounting hole, right bush mounting hole at both ends, outer bush and left bush mounting hole, right bush mounting hole interference fit on the good connector of riveting, the inside lining cover is used 638 solid glue and is closely inlayed at the outer bush, convenient many years back wearing and tearing change. When a bedplate track wheel shaft of the printing machine is stretched under the action of positioning force, the upper spring steel plate and the lower spring steel plate stretch, and the distance between shafts automatically increases; when the bedplate rail wheel axle of calico printing machine bulldozes at the location effort, go up spring steel board, lower spring steel board then by axial compression interaxial distance shorten to this completion tolerance compensation, make the calico printing machine of multistation, hundreds of stations even offset accumulative tolerance and wearing and tearing tolerance, smooth-going, swift locking station more, the strong striking of locating part because of the tolerance leads to when reducing the locking station improves calico printing machine precision and life.

The printing process is more and more complex in recent years, the larger the oval printing machine is, the more the number of the original twenty-three bedplate stations is increased to seventy-eight bedplate stations and even more hundred bedplate printing stations, and the huge automation equipment has higher and higher requirements on the machining precision of mechanical workpieces and the overall assembly precision of the whole machine. In a printing workshop, because the humidity is high under the action of an atomizing humidifier and a water curtain, a large amount of cloth hair, dust, oil stains and the like exist, the traditional table board connector adopting a spiral spring and a bearing structure can be frequently clamped to be worn, and the precision is poor or even the table board connector is broken. The coupler of the invention does not need oil feeding maintenance, is not afraid of oil stain and dust, is not influenced by humidity and temperature, does not need manual adjustment, can automatically adjust the axial distance of the section according to the actual positioning distance of the working station of the section when the printing machine operates at a locking position, and can automatically stretch if the axial distance of the section is not enough for the locking position, so that the spring steel plate is stretched, and the axial distance is increased; if the positioning distance of the section is too large, the axial middle parts of the two ends are pushed and pressed during positioning, the connector is compressed, and the spring steel plate expands to shorten the axial distance so as to compensate and offset the distance tolerance. The invention has the following advantages: 1. simple structure and lower cost. 2. The adjustment is not needed, the installation time and the whole machine debugging time are saved, and the labor cost is reduced. 3. The distance between two shafts is adjusted automatically, the compression is shortened, and the stretching is lengthened. 4. Stable, high positioning precision of machine operation and less noise. 5. The printing machine operates for a long time, does not need to be adjusted periodically, and can automatically compensate the axial distance tolerance by stretching or compressing during positioning. 6. Through the use verification of a nearly thousand-bar connector mounting machine of hundreds of printing machines for three years, the precision maintenance is very high, the damage of other parts caused by the impact of a positioning part is avoided, the integral stability and the service life of the printing machine are indirectly improved, and the printing machine is really durable.
