DETAILED DESCRIPTION
[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0018] For example, see Figures 1-4 A computer hardware performance testing platform includes a testing platform body 100, the top of the testing platform body 100 is respectively equipped with a fixed seat 200 and an electric telescopic rod 300, the fixed seat 200 is internally rotatably connected with a screw rod 400 driven by a servo motor, the outer side of the screw rod 400 is connected with a movable seat 500 by setting a thread, the bottom of the movable seat 500 is equipped with a detection probe 600 driven by an electric push rod, and the side of the electric telescopic rod 300 is transmission-linked with a clamping plate 700, the detected part is placed on the testing platform body 100, the electric telescopic rod 300 is started, and the clamping plate 700 transmission-linked with the electric telescopic rod 300 is driven to move, and the detected part is preliminarily clamped, and then the servo motor is started to drive the screw rod 400 driven by the servo motor to rotate, and the movable seat 500 assembled on the screw rod 400 by threading moves accordingly, and after the detection probe 600 is moved to the specified position, the electric push rod is enabled to drive the detection probe 600 to move downward to the detected part, and the corresponding detection operation is performed; A hydraulic chamber 801 is fixedly connected to the outer side of the lead screw 400. A push block 803 is slidably connected to the inner wall of the hydraulic chamber 801 through an elastic telescopic rod 802, and an arc-shaped rod 804 is slidably connected to the side of the hydraulic chamber 801. When the device quickly performs continuous multi-point detection, the lead screw 400 rotates quickly, driving the hydraulic chamber 801 fixedly connected to the lead screw 400 to rotate quickly. Under the action of centrifugal force, the push block 803 in the hydraulic chamber 801 stretches the elastic telescopic rod 802 and slides in the hydraulic chamber 801, increasing the pressure in the hydraulic chamber 801 and driving the arc-shaped rod 804 slidably connected to the hydraulic chamber 801 to move.
[0019] A hydraulic device 805 is assembled between the detection table main body 100 and the telescopic end of the electric telescopic rod 300. One end of the hydraulic device 805 is slidably connected to a force-bearing rod 806. The force-bearing rod 806 is located at the bottom of the arc-shaped rod 804 and is in contact with the arc-shaped rod 804. The other end of the hydraulic device 805 is slidably connected to a push rod 807. When the arc-shaped rod 804 extends synchronously during rotation, it can squeeze the force-bearing rod 806, driving the force-bearing rod 806 to move downward. Cooperating with the hydraulic device 805 slidably connected to the force-bearing rod 806, the pressure in the hydraulic device 805 increases, driving the push rod 807 slidably connected to the hydraulic device 805 to move sideways.
[0020] A spring 808 is assembled on the side of the force-bearing rod 806. The end of the spring 808 away from the force-bearing rod 806 is assembled on the inner wall of the hydraulic device 805. A force-bearing plate 810 is assembled on the side of the clamping plate 700 through a spring 809. The push rod 807 moves sideways, and the push rod 807 immediately squeezes the force-bearing plate 810, causing the force-bearing plate 810 to move under force and applying an additional force to the clamping plate 700 through the spring 809. In this way, the fixing effect of the device in this case can be improved, making the use of the device more stable.
[0021] After the corresponding detection operation is completed, when the lead screw 400 stops rotating quickly, the push block 803 loses the action of centrifugal force and can be reset under the action of the elastic telescopic rod 802. Similarly, the arc-shaped rod 804 is reset. The force-bearing rod 806 immediately loses the restriction of the arc-shaped rod 804 and can be reset under the action of the spring 808. Similarly, the push rod 807 is reset. Facilitating the next use of the device.
[0022] A dust blowing component 900 for cleaning dust is assembled on the top of the detection table main body 100, and a buffer component 1000 for stabilizing the detected part is assembled inside the detection table main body 100.
[0023] When in use, the inspected piece is placed on the inspection table body 100, and the electric telescopic rod 300 is started to drive the clamping plate 700 connected to the electric telescopic rod 300 to move, and the inspected piece is initially clamped. Subsequently, the servo motor is started to drive the screw rod 400 driven by the servo motor to rotate, and the moving seat 500 assembled on the screw rod 400 by threads moves accordingly. After the detection probe 600 is moved to the specified position, the electric push rod is enabled to drive the detection probe 600 to move downward to the inspected piece to perform corresponding detection operations; when the device rapidly performs continuous multi-point detection, the screw rod 400 rotates rapidly, driving the hydraulic chamber 1 801 fixedly connected to the screw rod 400 to rotate rapidly, and the push block 803 in the hydraulic chamber 1 801 stretches the elastic telescopic rod 802 under the action of centrifugal force, and slides in the hydraulic chamber 1 801, so that the pressure in the hydraulic chamber 1 801 increases, driving the hydraulic chamber 1 801 to slide The connected arc rod 804 moves, and at this time the arc rod 804 extends synchronously during rotation, thereby squeezing the force-bearing rod 1 806, driving the force-bearing rod 1 806 to move downward, and cooperating with the hydraulic device 805 slidably connected to the force-bearing rod 1 806, so that the pressure in the hydraulic device 805 increases, driving the push rod 807 slidably connected to the hydraulic device 805 to move sideways, and the push rod 807 immediately squeezes the force-bearing plate 810, so that the force-bearing plate 810 is forced to move, and an additional force is applied to the clamping plate 700 through the spring 2 809; after completing the corresponding detection operation, when the screw rod 400 stops rotating rapidly, the push block 803 loses the action of centrifugal force and can be reset under the action of the elastic telescopic rod 802. Similarly, the arc rod 804 is reset, and the force-bearing rod 1 806 immediately loses the restriction of the arc rod 804 and can be reset under the action of the spring 1 808. Similarly, the push rod 807 is reset.
[0024] For example 2, please refer to Figures 1-6 On the basis of the first embodiment, the sootblowing assembly 900 includes a hydraulic bin 901, a cam 902 is fixedly connected to the outer side of the screw rod 400, a force rod 903 is slidably connected to one end of the hydraulic bin 901 close to the cam 902, a spring 904 is installed on the side of the force rod 903, and the end of the spring 904 away from the force rod 903 is installed on the inner wall of the hydraulic bin 901. When the screw rod 400 rotates rapidly, the cam 902 fixedly connected to the screw rod 400 can be driven to rotate. During the rotation of the cam 902, when the protruding part of the cam 902 rotates to the force-bearing rod 903, the force-bearing rod 903 is squeezed by the cam 902, so that the force-bearing rod 903 compresses the spring 3 904 and slides into the hydraulic chamber 2 901. As the cam 902 continues to rotate, when its protruding part moves away from the force-bearing rod 903, the force-bearing rod 903 can be reset under the action of the spring 3 904, so that the force-bearing rod 903 can move back and forth.
[0025] One end of the second hydraulic chamber 901 away from the second force-bearing rod 903 is slidably connected to a toothed rod 905. A rotating rod 906 is rotatably connected to the side of the main body 100 of the inspection table. A gear 907 and a deflector 908 are fixedly connected to the outer side of the rotating rod 906. The gear 907 is located at the top of the toothed rod 905 and is in a meshing state with the toothed rod 905. When the second force-bearing rod 903 moves reciprocally, in cooperation with the second hydraulic chamber 901 slidably connected to the second force-bearing rod 903, it can drive the toothed rod 905 slidably connected to the second hydraulic chamber 901 to start reciprocating movement. The reciprocating toothed rod 905 then drives the gear 907 meshing with it to reciprocally rotate, causing the gear 907 to drive the rotating rod 906 fixedly connected to it to rotate, and the rotating rod 906 then drives the deflector 908 fixedly connected to it to reciprocally swing.
[0026] An air pump 909 is assembled on the top of the main body 100 of the inspection table, and an air supply pipe 910 is assembled on the side of the air pump 909. When the deflector 908 reciprocally swings, the air pump 909 is activated. Through the air supply pipe 910 assembled on the side of the air pump 909 and the reciprocally swinging deflector 908, fast-flowing gas can be sent to various parts of the workpiece to be inspected, and dust and other impurities that may exist on the workpiece to be inspected can be blown out. This makes the detection result of the workpiece to be inspected placed for a long time by this device more accurate.
[0027] During use, on the basis of the first embodiment, when the lead screw 400 rotates rapidly, it can drive the cam 902 fixedly connected to the lead screw 400 to rotate. During the rotation of the cam 902, when the protruding part rotates to the position of the second force-bearing rod 903, the second force-bearing rod 903 is squeezed by the cam 902, causing the second force-bearing rod 903 to compress the third spring 904 and slide into the second hydraulic chamber 901. As the cam 902 continues to rotate, when the protruding part moves away from the position of the second force-bearing rod 903, the second force-bearing rod 903 can be reset under the action of the third spring 904. In this way, the second force-bearing rod 903 can be made to reciprocate. In cooperation with the second hydraulic chamber 901 slidably connected to the second force-bearing rod 903, it can drive the toothed rod 905 slidably connected to the second hydraulic chamber 901 to start reciprocating movement. The reciprocating toothed rod 905 then drives the gear 907 meshing with it to reciprocally rotate, causing the gear 907 to drive the rotating rod 906 fixedly connected to it to rotate, and the rotating rod 906 then drives the deflector 908 fixedly connected to it to reciprocally swing. At this time, the air pump 909 is activated. Through the air supply pipe 910 assembled on the side of the air pump 909 and the reciprocally swinging deflector 908, fast-flowing gas can be sent to various parts of the workpiece to be inspected, and dust and other impurities that may exist on the workpiece to be inspected can be blown out.
[0028] For the third embodiment, please refer to Figures 1-8, on the basis of the first and second embodiments, the buffer assembly 1000 includes a third hydraulic chamber 1001. The third hydraulic chamber 1001 is located at the bottom of the hydraulic device 805 and is in communication with the hydraulic device 805. A buffer chamber 1002 is slidably connected to the top of the third hydraulic chamber 1001. When the pressure in the hydraulic device 805 increases, that is, when the device quickly performs continuous multi-point detection, the pressure in the third hydraulic chamber 1001 communicated with the hydraulic device 805 increases synchronously, driving the buffer chamber 1002 slidably connected to the third hydraulic chamber 1001 to move upward.
[0029] An elastic telescopic block 1003 is arranged inside the buffer chamber 1002 to connect a buffer rod 1004. A buffer plate 1005 is assembled at the top of the buffer rod 1004. When the buffer chamber 1002 moves upward, the buffer plate 1005 assembled on the buffer chamber 1002 immediately moves to the bottom position of the detected part; at this time, if the detected part generates vibration during the detection process, the detected part can drive the buffer plate 1005 to move downward by a certain distance, so that the buffer plate 1005 drives the buffer rod 1004 fixedly connected thereto to compress the elastic telescopic block 1003 and move downward.
[0030] Friction rubber blocks 1006 are assembled on the inner wall of the buffer chamber 1002. When the buffer rod 1004 moves downward, the buffer rod 1004 immediately moves to the side position of the friction rubber block 1006, and is subjected to severe friction of the friction rubber block 1006, reducing its vibration amplitude. After the buffering is completed, it is slowly reset under the action of the elastic telescopic block 1003, thus completing a buffering operation. In this way, a certain buffering effect can be provided for the detected part in this case, improving the protection effect of the device on the detected part in this case.
[0031] When the device completes the detection operation, the pressure in the hydraulic device 805 returns to the initial state. Similarly, the buffer assembly 1000 is reset. This is convenient for the next activation of the buffer assembly 1000.
[0032] In use, based on the first and second embodiments, when the pressure in the hydraulic device 805 increases, that is, when the device quickly performs continuous multi-point detection, the pressure in the third hydraulic chamber 1001 connected to the hydraulic device 805 increases synchronously, driving the buffer chamber 1002 slidably connected to the third hydraulic chamber 1001 to move upward. The buffer plate 1005 assembled on the buffer chamber 1002 then moves to the bottom position of the workpiece to be detected. At this time, if the workpiece to be detected vibrates during the detection process, the workpiece to be detected can drive the buffer plate 1005 to move downward by a certain distance, causing the buffer plate 1005 to drive the buffer rod 1004 fixedly connected thereto to compress the elastic telescopic block 1003 and move downward. The buffer rod 1004 then moves to the side position of the friction rubber block 1006, and is subjected to strong friction from the friction rubber block 1006, reducing its vibration amplitude. After the buffering is completed, it slowly resets under the action of the elastic telescopic block 1003, thus completing a buffering operation. When the device completes the detection operation, the pressure in the hydraulic device 805 returns to the initial state. Similarly, the buffer assembly 1000 is reset.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
