The invention discloses a relay sophistication test mechanism which comprises a test stand, a drive device, a transmission chain and a transfer test device. The drive device drives the transfer test device to circulate along a guide rail groove through the transmission chain. The transfer test device comprises a transfer test frame, a rotating shaft, a test lifting plate, a test fixture plate and a jig plate drive part. The rotating shaft is rotationally arranged on the transfer test frame. The rotating shaft is provided with a cam. The cam abuts against or is separated from the test lifting plate. An elastic part is arranged between the test lifting plate and the transfer test frame. The rotating shaft is arranged outside the transfer test frame. The rotating shaft is provided with a connecting rod and a roller. The connecting rod is hinged on the transmission chain. The roller is accommodated in the guide rail groove in a rolling manner. According to the invention, the relay sophistication test mechanism is capable of transporting a relay in the movement form of a ferris wheel and occupies a small space; the relay is moved from the starting position on one side of the test stand to the end position on the other side, and the sophistication test is completed; the test time is fully used.

The invention discloses an automatic net folding and packaging all-in-one machine. The automatic net folding and packaging all-in-one machine is composed of a bar inserting mechanism, a first bar drawing mechanism, a bar pulling mechanism, a second bar drawing mechanism, a bar conveying mechanism, a net bearing mechanism, a net pressing mechanism and a controller which are mounted on a machine frame, wherein the machine frame is halved; one side of the machine frame is provided with the bar inserting mechanism, the first bar drawing mechanism, the second bar drawing mechanism and the bar conveying mechanism, the bar inserting mechanism and the first bar drawing mechanism are located at one end of the same side, the second bar drawing mechanism is located at the other end, and the bar conveying mechanism is mounted in the position, between the first bar drawing mechanism and the second bar drawing mechanism, of the machine frame horizontally; the bar pulling mechanism, the net bearing mechanism and the controller are mounted on the other side of the machine frame, the bar pulling mechanism is mounted on the machine frame horizontally, the net bearing mechanism is mounted in the position, below the bar pulling mechanism, of the machine frame, the net pressing mechanism is mounted in the position, above the bar pulling mechanism, of the machine frame, and the controller is mounted on the lateral face of the machine frame. The structural layout of the automatic net folding and packaging all-in-one machine is reasonable, nets are folded in order automatically at a time, no labor operation is needed during folding, so that the production efficiency is high, the labor intensity is high, and the folding effect is good.

The invention relates to a double-intermediate-shaft DCT (Dual Clutch Transmission) structure and a computing method of a gear transmission ratio thereof. The double-intermediate-shaft DCT structure comprises dual clutches, a solid input shaft and a hollow input shaft, wherein one ends of the solid input shaft and the hollow input shaft which are coaxially arranged are connected with the dual clutches, and a normally engaged gear is respectively arranged at each of the other end of the solid input shaft and the other end of the hollow input shaft; the hollow input shaft is matched with an even-number gear intermediate shaft through a normally engaged gear set, and the even-number gear intermediate shaft is matched with an output shaft through a gear set; the solid input shaft is matched with an odd-number gear intermediate shaft through the normally engaged gear set, the odd-number gear intermediate shaft is matched with the output shaft through a gear set; and the tail end of the solid input shaft is matched with the head end of the output shaft sequentially through an embedded bearing and five-gear seven-gear synchronizers, and the total transmission ratios of all the gears are distributed in a geometric progression manner from the seventh gear to the first gear. The double-intermediate-shaft DCT structure not only achieves a structure of four synchronizers and eight speed-variable gears, but also is compact in layout and shortened in lengths of the input shafts.
