The sixth cylinder 662 drives the fourth guide rod 664 to move outwards, the fourth guide rod 664 penetrates through the guide block 665 fixed on the vertical plate 661, so that the pressure head 666 presses the case cover of the 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, and the first connecting rod 667 hinged to the fourth guide rod 664 and the second connecting rod 668 form a planar connecting rod mechanism to move downwards to drive the clamping plate 6610 to perform tightening operation, so that the case is clamped and fixed simultaneously in the process of being pressed downwards, and automatic clamping and pressing operation is realized. After the motion is finished, the sixth cylinder 662 drives the fourth guide rod 664 to retreat, the pressure head 666 leaves the surface of the cover of the chassis, the clamping plate 6610 is pulled by the second connecting rod 668 to release the chassis, at the same time, the fourth cylinder 442 drives the sixth guide rod 444 to retreat, the support plate 445 descends away from the bottom of the chassis to slowly place the support plate on the conveyor track 41, the conveyor motor 45 is started to reversely rotate to retreat the chassis to the laser detection position, if the detection is qualified, the motion in the embodiment 1 is repeated, namely, the conveyor motor 45 is started to reversely rotate to drive the conveyor track 41 to clockwise move, the bottom of the chassis returns to the roller plate 28 through the assisting roller 14, after the rear end pushes against the push plate 32, the motion stops, at the same time, after the sensor in the chassis jacking mechanism 2 detects the position, a signal is sent to start the first cylinder 23 to drive the push rod 24 to retreat, the eccentric conical cam 25 moves backwards to move the cam follower 26 downwards, the first guide bar 27 moves the roller blade 28 down so that the chassis is placed on the roller 12 smoothly, and the roller transfer mechanism 1 continues to start to transfer the chassis to the next pack or other process.

The previous steps are the same, that is, after the measurement by the laser measuring instrument 56 is completed, the rapid return motion is performed on the second guide rail 52 to return to the initial point, the measurement information is fed back, and if the product flatness is not qualified, the subsequent pressing operation is required to perform deformation compensation. Firstly, the third cylinder 432 drives the fifth guide rod 434 to retreat inwards, the limit baffle 435 descends to allow the chassis to pass through, the conveyor motor 45 is started to rotate forwards to drive the conveyor track 41 to move anticlockwise so that the chassis moves forwards continuously 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, the limit baffle 435 blocks the chassis and the conveyor belt is adjusted to a stagnation mode, the chassis is in a stagnation state, the lifting support mechanism 44 is started, the fourth cylinder 442 pushes the guide rod 444 to ascend, the support plate 445 supports the bottom of the chassis and lifts the bottom of the chassis to be separated from the conveyor track 41, the pressing mechanism 6 enters a working state, the position of the limit collar 64 on the seventh guide rod 63 is adjusted in advance according to the height of the server to control the height of the mounting plate 65, so as to ensure that the pressing-clamping mechanisms 66 (4 in the figure, or the number can be defined according to the type and the length of the upper cover of the chassis, and the pressing-clamping mechanisms can be cooperatively pressed together according to the requirement of a measurement result if the upper cover is detected and displayed to be integrally arched, and only the pressing-clamping mechanism at the corresponding position is started if the upper cover is independently arched in the front and the back) are in a proper position to obtain the best pressing-clamping effect. Wherein, the working action of the single press-down clamping mechanism 66 is as follows: first, as shown in fig. 11(a), in the inactivated state, the pressing head 666 in the clamping mechanism 66 is at the highest initial position, and at the same time, the fourth guide rod 664 together with the first and second connecting rods hinged thereto pulls the clamping plate 6610 to maintain the loose clamping state, and a sufficient passing space is reserved under the mechanism to avoid obstructing the transportation of the chassis. The standby box moves to a proper position, at this time, 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 pressing head 666 presses the box cover of the chassis 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 planar link mechanism to move downwards along with the planar link mechanism to drive the clamping plate 6610 to perform clamping action, the chassis is clamped and fixed in the process of being pressed downwards, and the lateral walls of the chassis are prevented from being extruded and deformed by unidirectional pressing force. The principle of the shaping realized by the pressing operation in this case is shown in fig. 12, in the bending and forming process of the upper cover sheet metal part, the microcosmic inner part of the sheet metal part is accompanied by the elastic deformation and the plastic deformation of the material, when the external load is removed after the processing is finished, the elastic deformation of the elastic deformation generating area and the elastic deformation part in the plastic deformation area can generate the recovery phenomenon, because in the initial deformation stage of the sheet metal part, the stress generated by the bending in the sheet metal part is smaller than the yield stress of the material, so that the deformation area of the sheet metal part is in the elastic deformation state, after the external force is unloaded, the sheet metal part can still recover to the initial state, at the moment, the outer layer material in the bending area extends under the action of the tensile stress, the inner layer material is compressed under the action of the compressive stress, the property of the metal material is isotropic, each position can be approximately considered as the linear stress state, under the action of the stress, the tensile deformation area of the section is enlarged, the compressive deformation zone is reduced so that the stress neutral layer deviates from the geometric middle layer of the panel and moves inwards. And the plastic deformation generated in the plastic deformation area is retained, so that errors are generated between the final shape of the plate and the shape corresponding to the die, as shown in fig. 12(a), when the upper cover is locked with the box body, the upper cover is arched due to the side compression of the box body, as shown in fig. 12(b), however, the deformation is difficult to adjust and avoid in the bending process, and at this time, the box cover needs to be subjected to deformation compensation. By utilizing the resilience material property of the sheet metal part, the sheet metal part is subjected to reverse action load at the center of the sheet metal part and is pressed down until the box cover is bent downwards, as shown in fig. 12(c), the bent part enters the deformation state again at the moment, the bending degree of the sheet metal part is increased along with the downward movement of the pressing head, the tensile stress generated at the bent part is increased compared with the elastic deformation stage, the stress is transmitted from the center position to two sides, and due to the action of the tensile stress, the plastic deformation part of the sheet metal part firstly appears on the outer layer surface of the bent part and then appears on the inner layer surface, and gradually expands from the inner layer surface and the outer layer surface to the inner part, and the stress neutral layer continues to move inwards, and at the moment, the clamping structures at two sides keep the clamping state to better help the material to realize plastic transformation, and the side walls of the box body of the case are prevented from being extruded and deformed by the unidirectional pressing action force. When the pressure head moves downwards to a certain degree and the relative bending radius is small enough, the bending areas are all in plastic deformation, the tensile stress at the bending position at the stage reaches the maximum, a large number of researches show that although the stage is in pure plastic deformation, the elastic deformation part in the plastic deformation area still exists in the unloading process, and by utilizing the property, after the pressure head is withdrawn from the work, the upper cover generates a certain degree of rebound and is reset to a horizontal flat position, as shown in figure 12(d), the defect of upward arching of the plate material of the box cover is eliminated, and therefore the compensation for the deformation of the upper cover can be completed. In the process of compensating deformation, compensation values are added to the case generating assembly errors by utilizing the resilience property of materials, the dimensional over-tolerance generated in the production process is corrected, and the product data is not changed, so that the synchronous operation of automatic clamping and pressing is realized. After the operation is completed, as shown in fig. 11(c), the sixth air cylinder 662 drives the fourth guide rod 664 to retreat, the pressing head 666 leaves the surface of the cover of the case, 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 air cylinder 442 drives the guide rod 444 to retreat, the support plate 445 descends away from the bottom of the case to slowly place the support plate on the conveyor track 41, the conveyor motor 45 is started to reversely rotate, the case retreats to the laser detection position, at this time, if the detection is not qualified, the operation is continuously repeated until the operation is qualified, and then the operation in embodiment 1 is performed.

In the former cases, compensation and correction are performed on the case which is not completely pressed, that is, the measurement distance fed back by the laser measurement instrument is smaller than the rated distance, and if the case is excessively deformed in the initial state or after a certain pressing operation, so that deformation compensation cannot be performed by using the pressing operation, 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 perform yielding actions at the moment, the limiting baffle 435 descends, the conveyor motor 45 rotates forwards, the conveyor crawler 41 is driven to rotate anticlockwise, the scrapped case is conveyed forwards until the case is conveyed out of the whole device, and then the next period of operation is performed.
