Technical Field
The invention relates to the technical field of machining, in particular to a gluing-drilling-electromagnetic riveting compound device and a using method thereof.

Currently, aerospace products are being developed toward weight reduction and upsizing. Titanium alloy and composite structures are increasingly used for weight reduction. Because of the good compatibility of titanium alloy and composite materials, a large number of titanium alloy fasteners are adopted. The titanium alloy is a strain rate sensitive material, the yield ratio is high, and the traditional riveting process is difficult to meet the riveting quality requirement. In order to achieve the large-scale, meet the requirement of structural bearing capacity, high-strength large-diameter rivets are increasingly adopted. Because the riveting force of the traditional riveting process is insufficient, the deformation resistance of the material is difficult to overcome, and the high-strength large-diameter rivet forming is difficult to realize. There is therefore an urgent need to solve the above problems using a novel riveting process.
Electromagnetic riveting is a riveting method that converts electromagnetic energy into mechanical energy, plastically deforming rivets to obtain mechanical connection joints. The electromagnetic riveting quality is stable, the ideal interference fit can be realized, and the electromagnetic riveting device can be used for solving the problem that the rivet made of the strain rate sensitive material and the rivet with the large diameter are difficult to form. The traditional electromagnetic riveting adopts the induction type electromagnetic riveting principle, but the driving piece and the coil are difficult to be completely coupled, so that the energy utilization rate is low. Therefore, there is a need to improve energy utilization to more effectively solve the problem that low voltage forming high strength large diameter rivets and strain rate sensitive material rivets are difficult to achieve.
And although the composite material is widely applied to aerospace products due to excellent mechanical properties and corrosion resistance, the composite material is not always free from corrosion. Under certain conditions, the composite material can generate a galvanic effect when being connected, so that corrosion is generated, and the connection strength is obviously reduced. Measures are therefore required to solve the composite problems.
Meanwhile, the steps are complicated in general production, a plurality of sites are required to be rolled for next processing, and the efficiency is low.

step 1: gluing: placing the plate on a crawler belt transmission mechanism, controlling the crawler belt transmission mechanism to be opened through a controller, enabling the plate to move rightwards, enabling the glue spreader to rotate anticlockwise after contacting the glue spreader, driving the glue feeding roller to rotate, taking glue out of the glue container onto the glue spreader to glue the plate, and conveying the glued plate to a female die through the crawler belt transmission mechanism after coating;
step 2: drilling: placing an un-glued plate on the glued surface of the plate, controlling a lifting mechanism to drive a side pressing barrel and a drill bit mounting seat to move downwards vertically, pressing the side pressing barrel to the surface of the plate and tightly pressing the side pressing barrel, compressing a spring to prevent the plate from misplacement, enabling a drill bit to move downwards continuously, contacting the plate for drilling, and driving the side pressing barrel and the drill bit mounting seat to rise to the original position by the lifting mechanism after drilling;
step 3: electromagnetic riveting: placing the rivet in the machined drilling hole, rotating the T-shaped rotating rod, rotating the electromagnetic riveting mechanism to the position right above the drilling hole, enabling the riveting die to be in contact with the upper end face of the rivet, controlling the second lifting mechanism through the controller to enable the electromagnetic riveting mechanism to integrally descend to the rivet, pushing the riveting die, the amplifier, the secondary coil and the guide rod to move upwards relatively, and compressing the first buffer spring until the primary coil is in contact with the secondary coil; secondly, the controller controls the riveting equipment to complete the charging process of the capacitor, then the primary coil and the secondary coil are discharged simultaneously, discharge currents with opposite directions are generated in the two coils, and then electromagnetic repulsive force is generated in the two coils, at the moment, the primary coil moves upwards under the action of repulsive force, and the secondary coil drives a guide rod amplifier fixedly connected with the primary coil and the riveting die to move downwards so as to form rivets; and meanwhile, the primary coil and the secondary coil are damped, repulsive force acting on the secondary coil pushes the amplifier, the riveting die and the guide rod to move downwards, the first buffer spring is stretched, the second buffer spring is compressed, repulsive force acting on the primary coil enables the primary coil to move upwards, the hydraulic damper and the reset spring are compressed, and when the compression part of the reset spring rebounds, the hydraulic damper acts, the energy of the spring is consumed, so that the primary coil is quickly reset, and preparation is made for the next electromagnetic riveting.
