[0002] Metal material testing is the process of evaluating metal properties and quality through scientific methods. It covers composition analysis, mechanical property testing, and microstructure observation. Commonly used techniques include spectral analysis, hardness testing, metallographic microscopy, etc. to verify material strength, ductility, and corrosion resistance. The results of metal material testing can provide key basis for industrial product quality control and life assessment, help manufacturers optimize production processes, and ensure the applicability and safety of materials in fields such as machinery manufacturing and aerospace.

[0003] In the prior art, operators often use metal clamping tools to clamp and fix metal material samples when conducting metal material testing.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figures 1 to 8As shown, the embodiment of the present invention provides a metal clamping tool for material science experimental detection, including a pad 1, the lower surface of the pad 1 is movably connected to the detection table 2, the inner surface of the detection table 2 is movably sleeved with a hollow block 3, the upper surface of the hollow block 3 and the lower surface of the pad 1 are fixedly connected, the inner surface of the hollow block 3 is fixedly installed with a partition block 4 located inside the hollow block 3, the left and right sides of the bottom of the inner surface of the hollow block 3 are movably connected to a No. 1 movable block 5, the number of No. 1 movable blocks 5 is two, the upper surfaces of the two No. 1 movable blocks 5 are movably connected to a No. 2 movable block 6, the bottom of the inner surface of the two No. 1 movable blocks 5 is fixedly connected to a spring 7, the top of the spring 7 and the No. 2 movable block 6 is fixedly connected, the lower surfaces of the two No. 1 movable blocks 5 are fixedly connected with connecting blocks 8, the outer surface of the connecting block 8 and the inner surface of the bottom end of the hollow block 3 are movably connected, the front and rear sides of the lower surface of the hollow block 3 are fixedly connected with fixing plates 9, the rear surface of the fixing plate 9 is fixedly installed with No. 1 motor 10, the other end of the output shaft of the No. 1 motor 10 is fixedly sleeved with a single-threaded rod 11, the front end of the single-threaded rod 11 passes through the fixing plate 9 and extends to the front surface of the fixing plate 9, the outer surface of the single-threaded rod 11 is threadedly sleeved with a movable hinge plate 12, the upper surface of the movable hinge plate 12 is hinged with a hinged rod 13, and the other end of the hinged rod 13 is hinged to the outer surface of the connecting block 8.

[0029] When the operator starts the No. 1 motor 10, the operation of the No. 1 motor 10 will cause the single-threaded rod 11 to start rotating. At this time, the movable hinge plate 12 will move back and forth driven by the outer surface of the single-threaded rod 11. As the movable hinge plate 12 moves, the hinge rod 13 will rotate. At the same time, the other end of the hinge rod 13 will drive the connecting block 8, thereby causing the connecting block 8 and the No. 1 movable block 5 to start moving toward the outside of the hollow block 3 as a whole, and finally causing the two No. 2 movable blocks 6 to contact the lower surface of the inspection table 2, wherein the upper surface of the No. 2 movable block 6 and the lower surface of the inspection table 2 are on the same plane, and the spring 7 is made of a metal material with a low creep rate.

[0030] Among them, the lower surface of the detection table 2 is fixedly connected to the support plate 37, the upper surface of the partition block 4 and the lower surface of the pad 1 are fixedly connected, and the left side of the front surface of the fixed plate 9 is fixedly connected to the guide rod 14. The rear end of the guide rod 14 passes through the fixed plate 9 and the movable hinge plate 12 in sequence and extends to the rear surface of the fixed plate 9. The outer surface of the guide rod 14 and the inner surface of the movable hinge plate 12 are movably connected.

[0031] The sleeve connection design between the guide rod 14 and the movable hinge plate 12 enables the guide rod 14 to limit the moving direction of the movable hinge plate 12 , while also ensuring that the movable hinge plate 12 will not rotate while being driven by the single-threaded rod 11 .

[0032] Among them, the upper surfaces of the two No. 1 movable blocks 5 are fixedly connected with a round block 15 located on the inner surface of the No. 2 movable block 6, the top of the round block 15 is fixedly connected with a baffle 16, the outer surface of the baffle 16 is movably connected to the inner surface of the No. 2 movable block 6, the bottom of the outer surface of the round block 15 is movably connected with a socket ring 17, the outer surface of the socket ring 17 is fixedly socketed with the inner surface of the No. 2 movable block 6, and the lower surface of the socket ring 17 is movably connected to the upper surface of the No. 1 movable block 5.

[0033] The shape design of the round block 15 and the baffle 16 limits the overall moving direction of the second movable block 6, while the design of the baffle 16 and the sleeve ring 17 limits the overall moving range of the second movable block 6.

[0034] Among them, the upper surface of the pad 1 is fixedly connected to the limiting plate 18, the upper surface of the limiting plate 18 is fixedly connected to the guide plate 19, the inner surface of the limiting plate 18 is movably connected to the U-shaped block 24, the lower surface of the U-shaped block 24 is movably connected to the upper surface of the pad 1, and the front surface of the limiting plate 18 is fixedly installed with a hydraulic cylinder 25, the rear end of the hydraulic cylinder 25 passes through the limiting plate 18 and extends to the interior of the limiting plate 18 and is fixedly connected to the front surface of the U-shaped block 24.

[0035] When the operator starts the hydraulic cylinder 25, the U-shaped block 24 will start to move forward and backward as a whole. At the same time, the design of the limit plate 18 limits the overall moving direction of the U-shaped block 24, thereby ensuring the stability of the moving direction of the U-shaped block 24 during the movement process.

[0036] Among them, a fixed shaft 20 is fixedly connected to the middle part of the upper surface of the pad 1, the top end of the fixed shaft 20 is fixedly connected to the top of the guide plate 19 surface, and the upper side of the outer surface of the fixed shaft 20 is movably sleeved with an intermediate rod 21 located above the U-shaped block 24. There are two intermediate rods 21, and the front side of the lower surface of the two intermediate rods 21 is provided with a connecting groove 22.

[0037] The shape design of the fixed shaft 20 enables the two intermediate rods 21 to rotate only around the fixed shaft 20 as the axis.

[0038] The inner surface of the connecting groove 22 is movably connected to a driving cylinder 23 . There are two driving cylinders 23 , and the bottom ends of the two driving cylinders 23 are fixedly connected to the upper surface of the U-shaped block 24 .

[0039] The driving cylinder 23 will move along with the U-shaped block 24, and the design of the connecting groove 22 and the driving cylinder 23 allows the driving cylinder 23 to drive the intermediate rod 21 when the U-shaped block 24 and the driving cylinder 23 move forward and backward, thereby causing the two intermediate rods 21 to start rotating around the fixed shaft 20 as the axis.

[0040] Among them, both ends of the two intermediate rods 21 are hinged with transmission rods 26, the number of transmission rods 26 is four, and each two transmission rods 26 form a group. The other end of each group of transmission rods 26 is hinged with a mounting block 27, and the number of mounting blocks 27 is two. The outer surfaces of the two mounting blocks 27 are movably connected to the inner surface of the guide plate 19, and the outer surfaces of the front and rear sides of the two mounting blocks 27 are fixedly connected to the limit blocks 28, and the outer surface of the limit blocks 28 is movably connected to the guide plate 19.

[0041] When the middle rod 21 starts to rotate, the transmission rod 26 will start to rotate driven by the middle rod 21. At the same time, the other end of the transmission rod 26 will drive the mounting block 27, thereby causing the two mounting blocks 27 to start moving left and right as a whole. The design of the limit block 28 plays a role in keeping the mounting block 27 as a whole stable during the movement.

[0042] Among them, the inner surfaces of the tops of the two mounting blocks 27 are movably connected with the socket blocks 29, and there are two socket blocks 29. The outer surfaces of the two socket blocks 29 are fixedly connected with the clamping plates 30. The inner surfaces of the middle parts of the two mounting blocks 27 are movably connected with the plugs 31. The outer surfaces of the front and rear sides of the plugs 31 are movably connected with the inner surface of the middle part of the mounting block 27. The top of the plug 31 passes through the mounting block 27 and the socket blocks 29 in sequence and extends to the upper surface of the mounting block 27. The outer surface of the plug 31 is movably connected with the inner surface of the socket block 29. The inner surface of the middle part of the plug 31 is movably connected with the limiting column 32. The upper and lower ends of the limiting column 32 pass through the plug 31 and extend to the outside of the plug 31 and are fixedly connected to the mounting block 27.

[0043] The design of the mounting block 27, the sleeve block 29 and the plug 31 enables the plug 31 to move up and down along the inner surface of the middle part of the mounting block 27. When the plug 31 moves to the bottom of the inner surface of the middle part of the mounting block 27, the plug 31 will be separated from the inner surface of the sleeve block 29. At this time, the overall fixation of the sleeve block 29 will be released. The design of the limit column 32 prevents the plug 31 from being separated from the inside of the mounting block 27.

[0044] Among them, the inner surfaces of the bottoms of the two mounting blocks 27 are fixedly mounted with the No. 2 motor 33 located above the guide plate 19, the other end of the output shaft of the No. 2 motor 33 is fixedly sleeved with a round shaft 34, the outer surface of the round shaft 34 is fixedly sleeved with an active rod 35, the other end of the active rod 35 is hinged with a driven rod 36, and the other end of the driven rod 36 is hinged to the outer surface of the plug 31.

[0045] When the operator starts the second motor 33, the circular shaft 34 and the active rod 35 will begin to rotate, and the rotating active rod 35 will drive the driven rod 36, thereby causing the driven rod 36 to also start to rotate. At this time, the other end of the driven rod 36 will drive the bolt 31, thereby causing the bolt 31 to start to move up and down.

[0046] The working principle and use process of the present invention:

[0047] First, the operator inserts the hollow block 3 as a whole into the inner surface of the inspection table 2. At this time, the upper surface of the No. 2 movable block 6 will be flush with the lower surface of the inspection table 2. At this time, the operator starts the No. 1 motor 10. As the No. 1 motor 10 runs, the single-threaded rod 11 will begin to rotate. At this time, the movable hinge plate 12 will begin to move backward under the drive of the single-threaded rod 11. At the same time, the hinged rod 13 will begin to rotate, and the other end of the hinged rod 13 will drive the connecting block 8, thereby causing the connecting block 8 and the No. 1 movable block 5 to start moving toward the outside of the hollow block 3 as a whole. When the upper surface of the No. 2 movable block 6 no longer contacts the dividing block 4, the No. 2 movable block 6 will support the lower surface of the inspection table 2 under the elastic force of the spring 7. At this time, the pad 1 as a whole will be fixed under the joint action of the pad 1, hollow block 3, No. 1 movable block 5, No. 2 movable block 6 and spring 7.

[0048] Then the operator inserts the socket block 29 that matches the shape of the metal sample into the inner surface of the top of the mounting block 27, and aligns the hole of the socket block 29 with the hole on the top of the mounting block 27. Then the operator starts the No. 2 motor 33. As the No. 2 motor 33 runs, the circular shaft 34 and the active rod 35 will begin to rotate. At this time, the other end of the active rod 35 will drive the driven rod 36, thereby causing the driven rod 36 to rotate. At the same time, the other end of the driven rod 36 will drive the plug 31, thereby causing the plug 31 to start moving upward. Finally, the top of the plug 31 will pass through the inner surface of the socket block 29 and move to the upper surface of the mounting block 27. At this time, the socket block 29 as a whole will be fixed inside the mounting block 27.

[0049] Then the operator places the metal sample between the two clamping plates 30 and starts the hydraulic cylinder 25. As the hydraulic cylinder 25 runs, the U-shaped block 24 and the driving cylinder 23 will start to move forward. The movement of the driving cylinder 23 will drive the intermediate rod 21, thereby causing the two intermediate rods 21 to rotate, and the transmission rod 26 will rotate with the rotation of the intermediate rod 21. At the same time, the other end of the transmission rod 26 will drive the mounting block 27, thereby causing the two mounting blocks 27 as a whole to start moving toward each other under the restriction of the limit block 28 and the guide plate 19. Finally, the two clamping plates 30 will contact the metal sample and clamp the metal sample, thereby facilitating the subsequent material testing work.
