Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A metal material strength testing machine includes a base 1, a support frame 11 fixedly connected to the surface of the base 1, a testing table 12 fixedly connected to the surface of the base 1, a testing mechanism provided on the surface of the support frame 11, the testing mechanism including a first motor 2, the first motor 2 fixedly connected to the surface of the support frame 11, a lead screw 21 fixedly connected to the output shaft of the first motor 2, a moving plate 22 threadedly connected to the surface of the lead screw 21, a hydraulic cylinder 23 fixedly connected to the surface of the moving plate 22, a connecting plate 24 fixedly connected to the piston rod of the hydraulic cylinder 23, a guide rod 25 fixedly connected to the lower surface of the connecting plate 24, a testing block 26 fixedly connected to the bottom of the guide rod 25, and a clamping mechanism provided at the bottom of the support frame 11, the clamping mechanism including a clamping cylinder 27 fixedly connected to the bottom of the support frame 11. A clamping block 28 is fixedly connected to the piston rod. A shielding mechanism is provided on the surface of the support frame 11. The shielding mechanism includes a support plate 3, which is fixedly connected to the top of the support frame 11. A rotating rod 31 is rotatably connected to the surface of the support plate 3. A shielding plate 32 is fixedly connected to the surface of the rotating rod 31. A second motor 33 is fixedly connected to the surface of the support plate 3. A bidirectional worm gear 34 is fixedly connected to the output shaft of the second motor 33. A worm wheel 35 is fixedly connected to the surface of the rotating rod 31. This detection mechanism can adjust the detection position. By detecting at different positions, the uniformity of material properties can be evaluated to ensure the overall quality of the product. Furthermore, this detection machine can shield flying debris in the metal material detection chamber through the shielding plate 32, avoiding detection tasks when not shielded and ensuring the safety of the metal material detection process.

[0024] Furthermore, the support frame 11 is U-shaped, and a guide hole is provided at the top of the support frame 11. The first motor 2 drives the lead screw 21 to rotate on the guide hole of the support frame 11 through the output shaft. The lead screw 21 changes the position of the moving plate 22 by rotating, thereby changing the detection position of the metal material.

[0025] Furthermore, a threaded hole is provided on one side of the movable plate 22, and the lead screw 21 is threadedly connected to the threaded hole of the movable plate 22. The lead screw 21 drives the movable plate 22 to slide on the guide hole of the support frame 11 by rotation. After the lead screw 21 has rotated, it will lock the position of the movable plate 22 at the top of the support frame 11. The movable plate 22 drives the detection block 26 to move synchronously through the guide rod 25. The movement of the detection block 26 changes the position of the detection block 26 above the metal material.

[0026] Furthermore, a guide hole is provided on the surface of the movable plate 22. The hydraulic cylinder 23 drives the connecting plate 24 to rise and fall on the movable plate 22 through the piston rod. The connecting plate 24 drives the guide rod 25 to slide on the guide hole of the movable plate 22. The guide rod 25 drives the detection block 26 to slide and rise synchronously. During the descent, the detection block 26 performs strength testing on the metal material on the testing table 12 by squeezing.

[0027] Furthermore, two sets of clamping cylinders 27 and clamping blocks 28 are provided. The clamping cylinders 27 drive the clamping blocks 28 to slide on the surface of the testing table 12 through the piston rod. The two sets of clamping blocks 28 will move in opposite directions, so that the two sets of clamping blocks 28 can clamp the metal material on the surface of the testing table 12, ensuring the stability of the metal material during the testing process.

[0028] Furthermore, the shielding plate 32 rotates on the surface of the support plate 3 via the rotating rod 31. Two sets of shielding plates 32 are provided and symmetrically distributed on both sides of the support frame 11. The height of the shielding plate 32 is slightly lower than the height of the support frame 11. The shielding plate 32 can be rotated to contact the surface of the support frame 11. At this time, the two sets of shielding plates 32 cooperate with the support frame 11 to shield the detection area and prevent debris from splashing.

[0029] Furthermore, during testing, the second motor 33 drives the bidirectional worm gear 34 to rotate via its output shaft. The bidirectional worm gear 34 simultaneously meshes with two sets of worm wheels 35. During its rotation, the bidirectional worm gear 34 drives the two sets of worm wheels 35 to rotate in opposite directions. The worm wheels 35 drive the baffle plate 32 to rotate on the top of the support frame 11 via the rotating rod 31, thereby enabling the two sets of baffle plates 32 to close simultaneously on both sides of the support frame 11.

[0030] Working principle: When inspecting metal materials on the inspection table 12, the output shaft of the second motor 33 drives the bidirectional worm gear 34 to rotate. The bidirectional worm gear 34 simultaneously drives two sets of worm wheels 35 to rotate. The worm wheels 35 drive two sets of baffle plates 32 to rotate at the bottom of the support frame 11 through the rotating rod 31. This causes the two sets of baffle plates 32 to rotate until they contact and connect with the surface of the support frame 11. The baffle plates 32, together with the support frame 11, shield the inspection area of ​​the inspection table 12, preventing the inspection task from being carried out without shielding, and ensuring the safety of the metal material inspection process.

[0031] The metal material is clamped at the center of the testing table 12 by the clamping cylinder 27 and the clamping block 28. The output shaft of the first motor 2 drives the lead screw 21 to rotate on the guide hole of the support frame 11. The lead screw 21 drives the moving plate 22 to slide on the guide hole of the support frame 11. During the sliding process, the moving plate 22 changes the position of the hydraulic cylinder 23, the connecting plate 24, the guide rod 25 and the testing block 26, thereby changing the testing position of the testing block 26 on the metal material. By testing at different positions, the uniformity of material properties can be evaluated to ensure the overall quality of the product.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
