The induction ring 508 is fixedly installed on the outer surface of the rotating rod 501 above the sleeve rod 502, and the proximity sensor 509 is installed on the lifting component 6. When the induction ring 508 follows the rotation and downward movement of the rotating rod 501, if the proximity sensor 509 senses the induction ring 508, the locking component 5 stops rotating and moving downward, and prepares to start the lifting process of the lifting component 6. The switching process is controlled by a pre-set program at the back end to determine the switching time point between the two processes.

[0057] refer to Figure 7-Figure 9 The lifting assembly 6 includes a moving frame 601 connected to the lower end of the moving screw rod 408, a second support plate 602 arranged below the moving frame 601, a gear transmission part 604 fixedly installed on the upper surface of the second support plate 602, a second driving motor 603 fixed to the input end of the gear transmission part 604 through a rod, a fixing plate 617 fixed above the second driving motor 603, a cam 605 fixedly connected to the output end of the gear transmission part 604, and a support roller 606 frictionally connected to the lower surface of the cam 605, the lower surface of the cam 605 is set as an upslope surface and a downslope surface, specifically, the first shaft sleeves 607 are installed at the four corners of the second support plate 602, and abut against the lower surface of the upper part of the sleeve rod 504;

[0058] At least two groups of second sleeves 608 are installed on the front and rear sides of the second support plate 602, and fixing bolts 613 are installed inside the second sleeves 608. The lower end of the fixing bolts 613 is fixedly connected to a square plate 614. The middle part of the square plate 614 is used to install the support roller 606, and the support roller 606 is rotatably connected in the empty groove set inside the square plate 614.

[0059] refer to Fig.10 The cam 605 is located below the second support plate 602. A rotation sensing part 609 is installed on the side wall of the cam 605 at the lower end of the upslope surface. Three groups of rotation sensing parts 610 are evenly distributed at 120° on the outer circle of the cam 605. The three groups of rotation sensing parts 610 are fixed to the lower surface of the second support plate 602. The rotation sensing part 610 is used to sense the position of the rotation sensing part 609, thereby determining the rotation angle of the cam 605.

[0061] A cooling box 8 is fixedly connected to the bottom of the square plate 614. The cooling box 8 is used to perform cooling and heat dissipation during product testing. A fixed module is fixedly connected to the bottom of the cooling box 8. The fixed module adopts a buckle structure. The product is installed at the bottom of the cooling box 8, and is locked and connected to the sheet metal part 3 through screws after the product is installed.

[0062] The module signal is connected to a control processor for executing the locking and lifting processes of the module.

[0063] In this embodiment, if Figure 1As shown, the base 1 is installed on the machine 2, and the control processor is started, and the first drive motor 401 drives the second transmission column 406 and the rotating drum 409 to rotate through the transmission belt, and the rotating rod 501 rotates and moves downward through the slide groove setting in the rotating drum 409, and the rotating rod 501 drives the sleeve rod 1 502, the sleeve rod 2 504, the lock head 505, the silicone tube 506, the lock cylinder 507, and the induction ring 508 to move downward and rotate synchronously, wherein the rotation direction of the four sets of locking components 5 is consistent, and the locking components 5 rotate and move downward. During the process, the spiral transmission part 407 starts and drives the movable screw rod 408 to move downward, so that the locking assembly 5, the lifting assembly 6 and the limit assembly 7 move downward to the position where the product needs to be clamped with the sheet metal part 3. During the process of the spiral transmission part 407 driving the movable screw rod 408 to move downward, the movable frame 601 will contact the second spring 703, and the second spring 703 applies a certain supporting force to the movable frame 601 to prevent damage to the product. This is the downward movement process of the module, and this position is defined as the first height position of each downward moving component.

[0064] After reaching the first height position, the spiral transmission part 407 stops driving the moving screw rod 408, and the first driving motor 401 is started, and the transmission column 2 406 and the rotating drum 409 are driven to rotate again through the transmission belt, and the rotating rod 501 drives the sleeve rod 1 502, the lock head 505, the silicone tube 506, the lock cylinder 507, and the induction ring 508 to move down and rotate synchronously, and the lock head 505 rotates the lock cylinder 507 through the universal joint structure, and the lock cylinder 507 performs a locking process with the screw column below. In this process, the proximity sensor 509 detects the position of the adjacent induction ring 508. When the proximity sensor 509 detects When the induction ring 508 is detected, it means that the lock head 505 has reached the locking position, the elastic part 503 is compressed by the downward pressure of the sleeve rod 1 502, the upper part of the sleeve rod 1 502 and the upper part of the sleeve rod 2 504 approach and tend to contact, the first drive motor 401 is turned off, and when the four lock heads 505 complete the preliminary locking process with the corresponding screw columns respectively, the distance between the second support plate 602 and the sheet metal part 3 remains fixed. At this time, the position of the second support plate 602 is defined as the second height position. When the second support plate 602 reaches the second height position and the lock head 505 reaches the locking position, it means that the preliminary locking process is completed.

[0065] When the proximity sensors 509 detect the corresponding induction rings 508 respectively, the lifting process is started, the second drive motor 603 is started, and its output end drives the cam 605 to rotate through the gear transmission part 604. The upslope surface of the cam 605 makes friction contact along the surface of the support roller 606 and applies downward pressure to the support roller 606. Under the interaction of forces, the support roller 606 applies an upward thrust to the cam 605, and the cam 605 drives the second support plate 602 and the structure connected thereto to perform a lifting action. The lock head 505 will drive the screw column to move upward, and the torsion spring connected to the screw column will be stretched. The torsion spring is tightened through the screw The column will also apply a reverse downward pulling force to the lock head 505 to complete the lifting process of the module. For example, in the initial locking process, the force value of the product is preset to be F. Under the pulling action, the force value of the product will be reduced to f, and f is the pressure value required in the subsequent performance test. The force value f of the product will be determined according to the rotation angle of the cam 605. In addition, after being placed in the performance testing machine, the pressure adjustment can be performed during or before the test, that is, through command control, the angle change of the cam 605 is used to adjust the force value in real time, so as to make the pressure adjustment required during the test or further improve the test accuracy.

[0066] The limiting component 7 forms a connection relationship between the limiting shaft 701 and the movable frame 601 and the second support plate 602. In the above-mentioned downward movement process, preliminary locking process and pulling process, the limiting component 7 moves synchronously with the second support plate 602, performs limiting movement on the second support plate 602, and the movable frame 601 slides relatively on the surface of the limiting shaft 701. When the first spring 702 and the second spring 703 contact the movable frame 601, a certain supporting force is applied to the movable frame 601 to ensure the movement stability of the movable frame 601 and prevent damage to the product.

[0067] The product is first installed in the fixed module at the bottom of the cooling box 8, and then the product is clamped and installed through the lowering process, the preliminary locking process and the pulling process, and then the machine 2 is placed in the performance testing machine. A heat sink is provided in the cooling box 8, and liquid pipes are connected at both ends for heat dissipation during the test. Details are not given here. The cooling box 8 is fitted with the product during the clamping process of the product to facilitate the installation of the heat dissipation structure. The module not only realizes the installation of the heat dissipation structure, but also ensures that the product is clamped under the preset force value, and ensures that the force of the product meets the regulations; the synchronous locking of the screw columns by four or more locking heads 505, as opposed to the one-by-one locking method, not only saves time, but also ensures that the force of the product is uniform during the clamping process, thereby reducing the damage rate of the product.

[0068] Embodiment 2. On the basis of Embodiment 1, the following structure is added: Displacement induction rods 706 and displacement induction blocks 901 are fixedly connected to the middle parts of two groups of limit plates 704 respectively. The detected end of the displacement induction block 901 facing the groove-type induction switch II 902 is set to be convex. Groove holes for facilitating the movement of the displacement induction rods 706 and the displacement induction blocks 901 are formed in the base 1. A groove-type induction switch I 707 is installed on one side of the upper surface of the base 1 close to the displacement induction rod 706, and a groove-type induction switch II 902 is installed on one side of the upper surface of the first support plate 402 close to the displacement induction block 901. By arranging both the displacement induction rods 706 and the displacement induction blocks 901 on the limit plates 704 of the limit assembly 7, it is used to monitor the movement of the limit assembly 7. The groove-type induction switch I 707 and the groove-type induction switch II 902 utilize the photoelectric effect and the U-shaped groove design. Infrared emission areas and infrared reception areas are formed on both sides of the U-shaped groove. When the displacement induction rods 706 and the displacement induction blocks 901 enter the U-shaped groove and block the optical axis, through the change of the optical signal, it is converted into an electrical signal and transmitted to the control processor, thereby determining the movement of the limit assembly 7.

[0069] In the initial state of the module, the lower end of the displacement induction rod 706 is located above the groove-type induction switch I 707, and the optical axis is not blocked. Therefore, the groove-type induction switch I 707 is in the optical axis transmission state; the convex detected end of the displacement induction block 901 is located in the middle of the groove-type induction switch II 902, blocking the optical axis. Therefore, the groove-type induction switch II 902 is in the optical axis blocking state. In the downward movement process, the displacement induction block 901 moves downward towards the lower part of the groove-type induction switch II 902, and the optical axis in the groove-type induction switch II 902 is in the transmission state, indicating the downward movement state of the limit assembly 7. When the optical axis of the groove-type induction switch I 707 is blocked by the displacement induction rod 706, it indicates that the downward movement process is completed. The groove-type induction switch I 707 transmits a signal to the control processor, and the screw drive part 407 controls the moving screw rod 408 to stop synchronously moving downward, completing the signal transmission corresponding to the downward movement process and reaching the position where the product is to be locked.

[0070] In addition, referring to Fig. 9 , C-shaped parts 611 are fixedly installed on both sides of the square plate 614, and displacement sensors 612 are installed on the front and rear sides of the C-shaped parts 611 respectively; The displacement sensor 612 can be but is not limited to a laser ranging sensor, which is suitable for ranging installation.

[0071] Referring to Fig.11An auxiliary detection part 615 is fixedly installed on one side of the front surface of the movable frame 601 through a rod, and an anti-foolproofing sensor 616 is fixedly connected to one side of the fixed plate 617 close to the auxiliary detection part 615 for anti-foolproofing processing; the anti-foolproofing sensor 616 also uses the photoelectric principle to detect the position state of the auxiliary detection part 615, thereby realizing an automated anti-foolproofing mechanism; specifically, in the downward movement process, the movable frame 601 slides on the limit shaft 701, and the auxiliary detection part 615 follows the movable frame 601 to move downward under the action of the moving screw 408. When the anti-foolproofing sensor 616 detects the auxiliary detection part 615, it indicates that the downward movement process is completed, and the sensing results of the slot-type induction switch 707 are compared. If the signals are consistent, it indicates that the product has reached the position to be locked. If the signals are inconsistent, the control processor will send an alarm signal, and the module will stop moving, waiting for the staff to check the components to prevent damage to the product in subsequent actions.

[0072] In the preliminary locking process, the proximity sensor 509 detects the adjacent induction ring 508. When the proximity sensor 509 detects the induction ring 508, the locking action stops, and the locking process of the locking head 505 on the screw column is completed.

[0073] Among them, the control processor is connected with the slot-type induction switch 1 707, the slot-type induction switch 2 902, and the anti-fool sensor 616 for signal transmission of electrical signals.

[0074] Embodiment 3, the method of using the cam-lifting CPU module is as follows:

[0075] S1: The product is first installed in the fixed module at the bottom of the cooling box 8, and then the base 1 is fixed to the machine platform 2.

[0076] S2: The control processor drives the locking assembly 5 and the screw transmission part 407 for a period of time T1 to complete the downward movement process of the module and reach a preset first height position.

[0077] When executing the downward movement process, four groups of displacement sensors 612 arranged in a square distribution respectively monitor the positions of the three groups of proximity sensors 509 and the bottom surface of the auxiliary detection part 615 that move downward synchronously. It should be noted that, in the initial connection state, the bottom surfaces of the three groups of proximity sensors 509 and the auxiliary detection part 615 are at the same height, and the distances measured by the four groups of displacement sensors 612 from the bottom surfaces of the three groups of proximity sensors 509 and the auxiliary detection part 615 are recorded as L1, L2, L3, and L4 respectively;

[0078] S21: Before starting the locking assembly 5 and the spiral transmission part 407, the distances measured by the four sets of displacement sensors 612 are required to be equal, that is, L 初= L1 = L2 = L3 = L4, the bottom surfaces of the three groups of proximity sensors 509 and the auxiliary detection unit 615 are all at the same height, otherwise it means that there is a deviation in the previous installation and debugging, and the downward movement process is suspended to adjust or replace the module to ensure the effective execution of the subsequent process;

[0079] S22, on the basis of ensuring that the bottom surfaces of the three groups of proximity sensors 509 and the auxiliary detection unit 615 are at the same height level, the downward movement process is started, and the four groups of displacement sensors 612 regularly detect the corresponding distances to obtain the downward movement distance change value △L ij , i is an integer between 1 and 4, which represents the serial numbers corresponding to the three groups of proximity sensors 509 and the auxiliary detection unit 615 in sequence; j is the serial number of the predetermined detection time point;

[0080] △L 1j , △L 2j , △L 3j It needs to be consistent and the ideal value is 0, because the proximity sensors 509 are all fixed to the side of the fixing plate 617, and the downward movement distance of the displacement sensing rod 706 is consistent with the proximity sensor 509;

[0081] △L 4j The moving screw rod 408 drives the auxiliary detection part 615 to move downward through the moving frame 601, and the moving speed of the auxiliary detection part 615 is slightly faster than the moving speed of the proximity sensor 509 and the displacement sensing rod 706, so that the moving frame 601 contacts the second spring 703, and ensures that the foolproof sensor 616 can detect the auxiliary detection part 615, so as to correspond and verify whether the displacement sensing rod 706 and the slot-type sensing switch 1 707 are inductively sensed, so as to end the downward movement process;

[0082] Through △L 1j , △L 2j , △L 3j Whether it is consistent, determine whether the locking assembly 5 moves down smoothly, and confirm the locking assembly 5 with problems according to the actual change value of the downward movement distance. If there is a problem, directly enter S5 and issue an alarm at the control processor;

[0083] Pre-debugging: When the foolproof sensor 616 detects the auxiliary detection part 615, the slot-type induction switch 1 707 just senses the displacement sensing rod 706; when the locking assembly 5 moves down normally, if the induction time of the two does not correspond, it means that the second spring 703 has a performance weakening problem or the moving screw 408 has a connection problem. If the subsequent locking process is continued, the product will be damaged by pressure. In this case, the subsequent process is suspended and S5 is entered;

[0084] If the situation is normal, execute S3.

[0085] S3: Stop driving the spiral transmission part 407, and keep the locking assembly 5 in the driving state for a period of time T2, and determine whether the locking position is reached by detecting the induction ring 508 by the proximity sensor 509.

[0086] If the proximity sensors 509 all detect the induction rings 508 at the same time, it means that the four sets of lock heads 505 have all reached the corresponding locking positions. If the proximity sensors 509 detect the induction rings 508 with a time deviation, whether to execute the locking process will be determined according to the time deviation;

[0087] When the deviation is small, if the first drive motor 401 is paused at the same time, the lock head 505 drives the lock cylinder 507 to rotate and tighten to a nearly consistent height, and the difference in the number of tightening turns can be ignored; when the deviation is large, the difference in the number of tightening turns cannot be ignored, and the difference will obviously affect the subsequent lifting effect, and directly enter S5.

[0088] S4: After reaching the locking position, the lifting assembly 6 is driven for a period of time T3 to adjust the force value.

[0089] The force value is preset manually, and the lifting adjustment is achieved by adjusting the contact points between the upslope surface and the downslope surface of the cam 605 and the support roller 606.

[0090] S5: End the process.
