The utility model discloses a theory of operation and working process as follows:

manually placing the flange plate and the bearing on a carrier, conveying the flange plate and the bearing plate to be pressed to a press through a circulation conveying line, pressing the flange plate and the bearing plate, and then grabbing the flange plate to a lettering detection line by a grabbing mechanism to perform subsequent processing; meanwhile, the belt carrier of the circulating conveying line reflows to the original position to prepare the next action process; in the process of the lettering detection line, the third conveying track drives the carriers to flow, lettering, appearance detection and the like are sequentially carried out, and finally, blanking is carried out at the position of the material distributing device according to good products and defective products;

the concrete working process of the transfer conveying line is as follows:

conveying the empty carrier to the end part (defined as the left end) of the first conveying track through the first conveying track (driven by a belt conveying structure), wherein at the moment, one side surface of a triangular plate of a shifting plate seat is just aligned with the side surface of the carrier, placing a flange plate of a bearing to be pressed and the bearing into the carrier, driving the shifting seat to translate along the Y direction by a Y-direction driving unit, driving the carrier to translate, conveying the carrier to a second conveying track through the auxiliary action of the connecting track and a shaft sleeve arranged on the connecting track, carrying out subsequent manufacturing procedures, driving the shifting seat to return by the Y-direction driving unit, and repeating the actions; in the process, when the carrier passes through the leveling mechanism, the distance between the roller and the upper surface of the connecting track is preset, if the carrier is discharged, the bearing is not completely aligned with the bearing hole, one side of the bearing can tilt, when the carrier passes through the roller, the roller can push the slightly dislocated bearing into the bearing hole, the problem of inaccurate manual discharging position is corrected to a certain extent, and material scrapping caused by subsequent material placement and press mounting due to inaccurate material placement is avoided;

the subsequent processes here refer to: the carrier is just clamped between limiting blocks arranged on the chain, then the carrier is driven by a chain wheel and chain transmission structure to move to a processing station (such as a press mounting station, a bearing is pressed into a flange plate through a press mounting machine), then the carrier is conveyed to the right end of a second conveying rail, namely a positioning device, after the sensor detects that the carrier is in place, a push rod of a first Z-direction driving cylinder retracts, a driving guide pillar moves upwards relative to a guide sleeve, so that a limiting column of a first positioning assembly is driven to extend upwards to the side face of the carrier, the carrier is clamped tightly through the matching of the limiting columns of the first positioning assembly and a second positioning assembly, and the movement of the carrier in the X direction is limited;

meanwhile, the driving end of the overturning driving cylinder retracts to drive the connecting block to move, and the two sides of the positioning wheel mounting seat can be perpendicular to the connecting platform through transmission between the rotating shaft and the positioning wheel mounting seat, namely, the part of the lower surface of the positioning wheel, which extends out of the positioning wheel mounting seat, presses the carrier from the upper part to form upper limit on the carrier, and limits the movement of the carrier in the Z direction and the Y direction to limit the carrier;

through the action process, the carrier is positioned, the carrier is prevented from moving, the flange plate after the bearing is pressed and mounted is taken away by matching with other mechanisms, if the positioning device is not provided, the function of taking away the flange plate independently can not be realized, and the flange plate taken away independently can be used for subsequent detection, laser lettering and the like;

then, the driving end of the overturning driving cylinder extends out to drive the connecting block to move, the two sides of the positioning wheel mounting seat can be clamped in the strip-shaped groove through transmission between the rotating shaft and the positioning wheel mounting seat, the circumferential surface of the positioning wheel faces upwards, interference of a carrier passing through the connecting platform is avoided, the carrier can be conveyed to the connecting platform through the second material conveying device, the carrier is conveyed to the right end of the first conveying rail through the second material conveying device, the first positioning component of the first positioning mechanism descends (the principle is the same as that of the positioning device), then the limiting driving cylinder of the limiting mechanism drives the limiting column head of the limiting component to extend into the limiting hole of the carrier to position the carrier, the carrier is conveyed to the left end of the first conveying rail through the belt transmission component, and the next process is repeated;

the working process of the material distributing device is as follows:

defining one side where a defective product conveying bin is located as a left side, describing the embodiment by taking a flange plate and a bearing as an example, after a material taking driving cylinder drives a material taking supporting claw to descend to the right position, the material taking supporting claw extends into a through hole of the bearing of the flange plate, then the supporting claw driving cylinder drives the material taking supporting claw to expand to grab the flange plate provided with the bearing, and the flange plate is conveyed to the right above a defective product conveying rail through a material taking driving unit; when the flange plate is a defective product, the flange plate is positioned on the left side of the material pushing plate, and the material pushing cylinder drives the material pushing plate leftwards to push the defective product to enter the defective product conveying bin.

The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures made by the contents of the specification and the drawings, or directly or indirectly applied to other related technical fields, are included in the same principle as the protection scope of the present invention.
