The sixth cylinder 662 drives the fourth guide rod 664 to move outwards, the fourth guide rod 664 passes through the guide block 665 fixed on the vertical plate 661, so that the pressing head 666 presses the box cover of the press box to perform deformation compensation operation, meanwhile, the connecting block 669 fixes the clamping plate 6610 on the second connecting rod 668 through bolt connection, the first connecting rod 667 hinged on the fourth guide rod 664 and the second connecting rod 668 form a plane connecting rod mechanism to move downwards along with the first connecting rod 667 so as to drive the clamping plate 6610 to perform clamping operation, and the box is clamped and fixed simultaneously in the pressing process, so that automatic clamping and pressing operation is realized. After the action is completed, the sixth cylinder 662 drives the fourth guide rod 664 to retract, the pressure head 666 leaves the surface of the case cover, meanwhile, the clamping plate 6610 is pulled up by the second connecting rod 668 to release the case, at this time, the fourth cylinder 442 drives the sixth guide rod 444 to retract, the supporting support plate 445 descends away from the bottom of the case and slowly places the supporting plate on the conveyor track 41, the conveyor motor 45 is started to rotate reversely, the case is retracted to a laser detection position, if the detection is qualified, the action in embodiment 1 is repeated, namely, the conveyor motor 45 is started to rotate reversely, the conveyor track 41 is driven to move clockwise, the bottom of the case passes through the auxiliary roller 14 and returns to the roller support plate 28, after the rear end is propped against the push plate 32, the action stops, at this time, after the position is detected by the sensor in the case jacking mechanism 2, a signal is sent, the first cylinder 23 is started to drive the push rod 24 to retract inwards, the eccentric conical cam 25 moves backwards to enable the cam follower 26 to move downwards, the first guide rod 27 drives the roller support plate 28 to slow down, thereby stably place the case on the roller 12, the roller conveying mechanism 1 continues to start to convey the case to the next package or other procedures.

The foregoing steps are consistent, that is, after the measurement of the laser gauge 56 is completed, a quick return motion is performed on the second rail 52 to return to the initial point, the measurement information is fed back, and if the flatness of the product is not qualified, a subsequent pressing operation is required to perform deformation compensation. Firstly, the third cylinder 432 drives the fifth guide rod 434 to retract inwards, the limit baffle 435 descends to allow the chassis to pass, the conveyor motor 45 is started to drive the conveyor crawler 41 to move anticlockwise to enable the chassis to continue to move forwards and travel to a proper position below the pressing mechanism 6, the sensor sends a signal to start a second limit mechanism component below the pressing mechanism 6, the sensor controls the third cylinder 432 to push the fifth guide rod 434 to ascend, at the moment, the limit baffle 435 blocks the chassis while the conveyor belt is adjusted to a stagnation mode, the chassis is in a stagnation state, at the moment, the lifting supporting mechanism 44 is started, the fourth cylinder 442 pushes the guide rod 444 to ascend, after the supporting plate 445 holds the bottom of the chassis and lifts it off the conveyor crawler 41, the presser mechanism 6 enters into a working state, and the position of the limiting collar 64 on the seventh guide rod 63 of the guide rod is adjusted in advance according to the height of the server to control the height of the mounting plate 65 so as to ensure the pressing-clamping mechanisms 66 (4 in the figure, the number can be defined according to the type and length of the upper cover of the chassis, and the upper cover can be cooperatively pressed together if the upper cover is detected and displayed to be arched integrally according to the requirement of the measurement result; if the front and the rear are singly arched, only the pressing clamping mechanism at the corresponding position is started) to be positioned at the proper position, so as to obtain the optimal pressing effect. Wherein, the working action of the single pressing clamp mechanism 66: first, as shown in fig. 11 (a), in the unactuated state, the pressing head 666 in the pressing chuck 66 is located at the initial position of the highest point, and at the same time, the fourth guide rod 664, together with the first and second links hinged to itself, pulls the clamping plate 6610 to maintain the loose state, and enough passing space is reserved below the mechanism to avoid obstructing the transmission of the chassis. When the case is moved to a proper position, referring to fig. 11 (b), the sixth air cylinder 662 drives the fourth guide rod 664 to move outwards, the fourth guide rod 664 passes through the guide block 665 fixed on the vertical plate 661, so that the press head 666 presses the case cover of the press case to perform deformation compensation operation, meanwhile, the connecting block 669 fixes the clamping plate 6610 on the second connecting rod 668 through bolt connection, the first connecting rod 667 hinged on the fourth guide rod 664 and the second connecting rod 668 form a plane connecting rod mechanism to move downwards along with the first connecting rod 667 to drive the clamping plate 6610 to perform clamping action, the case is clamped and fixed simultaneously in the pressing process, the case body is prevented from being extruded and deformed by unidirectional downward pressing force. In this case, the principle of shaping by the pressing operation is as shown in fig. 12, in the bending and shaping process of the upper cover sheet metal part, the elastic and plastic deformation of the material is accompanied by the removal of the external load after the processing is finished, the elastic deformation of the elastic deformation generating region and the elastic deformation part in the plastic deformation region can generate recovery phenomena, because the stress generated by bending in the sheet metal part at the initial stage of the sheet metal deformation is smaller than the yield stress of the material, the deformation region of the sheet metal is in an elastic deformation state, the sheet metal can still recover to the initial state after the external force is unloaded, the outer layer material of the bending region is stretched under the action of the tensile stress, the inner layer material is compressed under the action of the compressive stress, the metal material is isotropic, and each position can be approximately considered as a linear stress state, under the action of the stress, the tensile deformation area of the section becomes large, and the compressive deformation area is reduced, so that the stress neutral layer deviates from the geometrical middle layer of the plate material and moves inwards. The plastic deformation generated in the plastic deformation area is remained, so that errors are generated between the final shape of the plate and the shape corresponding to the mold, as shown in fig. 12 (a), and the rebound phenomenon causes arching due to side compression of the case when the upper cover is locked with the case, as shown in fig. 12 (b), however, the deformation is difficult to adjust and avoid in the bending process, and at this time, the case cover needs to be compensated for deformation. By utilizing the rebound material property of the sheet metal part, the sheet metal part is reversely acted with load at the center of the sheet metal part and is pressed down until the case cover is bent downwards, as shown in fig. 12 (c), the bending part is re-entered into a deformation state at the moment, as the pressure head moves downwards, the bending degree of the sheet metal part is increased, the tensile stress generated at the bending part is increased compared with the elastic deformation stage, the stress is transferred from the center position to two sides, the plastic deformation part of the sheet metal part firstly appears on the outer surface of the bending part and then appears on the inner surface due to the action of the tensile stress, the inner surface and the outer surface of the inner layer are gradually expanded inwards, the stress neutral layer is continuously moved inwards, the clamping structure at the two sides keeps the clamping state, and the plastic deformation of the material can be better assisted, the case body is prevented from being extruded and deformed by unidirectional downward pressing force. When the pressing head moves down to a certain extent and the relative bending radius is small enough, the bending areas are all plastic deformation, the tensile stress of the bending parts reaches the maximum at the stage, and a large number of researches show that although the stage is pure plastic deformation, in the unloading process, the elastic deformation part in the plastic deformation area still exists, by utilizing the property, after the pressing head exits from working, the upper cover rebounds to a certain extent and returns to the horizontal flat position, as shown in fig. 12 (d), the arch defect on the cover plate is eliminated, and the compensation of the deformation of the cover plate can be completed. The compensation deformation process is to add a compensation value to a chassis with assembly errors by utilizing the rebound property of materials, correct the out-of-tolerance dimension in the production process, and not change the product data, thereby realizing automatic clamping, pressing and synchronous operation. After the operation is completed, as shown in fig. 11 (c), the sixth cylinder 662 drives the fourth guide rod 664 to retract, the pressure head 666 leaves the surface of the case cover and rises to the initial position, and the clamping plate 6610 is pulled up by the second connecting rod 668 to release the case, at this time, the fourth cylinder 442 drives the guide rod 444 to retract, the supporting plate 445 descends from the bottom of the case to slowly place it on the conveyor crawler 41, the conveyor motor 45 is started to reverse, the case is retracted to the laser detection position, at this time, if the detection is failed, the operation is continued to repeat until the detection is qualified, and the operation in embodiment 1 is performed again.

The former cases are that compensation correction is performed on a chassis that is not properly pressed, that is, the measurement distance fed back by the laser measuring instrument is smaller than the rated distance, and if the chassis is in an initial state or after a certain pressing operation, the chassis cover is excessively deformed and cannot be subjected to deformation compensation by pressing operation, then embodiment 4 should be triggered: when the distance fed back by the laser measuring instrument 56 is greater than the rated distance, the two limiting mechanisms 43 are in a yielding action, the limiting baffle 435 is lowered, the conveyor motor 45 is rotated forward, the conveyor crawler 41 is driven to run anticlockwise, the scrapped chassis is conveyed forwards until the whole device is conveyed, and then the next period of operation is carried out.
