[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0030] As Figures 1 to 5 shown, the present utility model provides a strength detection device for metallurgical castings, including a detection box body 1 fixed on the ground. Lower support plates 2 for supporting the moving plate 4 are welded on both sides of the middle and lower parts of the detection box body 1. The lower end surface of the moving plate 4 is attached to the upper end surface of the lower support plate 2, thereby improving the supporting force of the moving plate 4.

[0031] On both sides of the upper end of the moving plate 4, a clamping mechanism one 3 and a clamping mechanism two 6 for clamping metal parts are symmetrically arranged respectively. On one side of the middle part of the upper end of the moving plate 4, a clamping mechanism three 7 is slidably arranged. The clamping mechanism three 7 is vertically arranged with the clamping mechanism one 3 and the clamping mechanism two 6. The structures of the clamping mechanism one 3, the clamping mechanism two 6, and the clamping mechanism three 7 are all the same in size;

[0032] The clamping mechanism one 3 and the clamping mechanism two 6 include a fixed sleeve 31 fixedly arranged at the upper end of the moving plate 4. A lifting rod 32 is longitudinally slidably arranged in the inner cavity of the fixed sleeve 31. The lifting rod 32 is threadedly fixed to the telescopic end of a hydraulic rod one 33. The fixed end of the hydraulic rod one 33 is fixed to the bottom of the inner cavity of the fixed sleeve 31 by screws. An L-shaped plate 36 is slidably arranged in the inner cavity of the upper end of the lifting rod 32. One end of the L-shaped plate 36 is in the same direction as the clamping plate 37 to achieve the clamping effect (as Figure 3 shown). The bottom of the inner cavity of the upper end of the lifting rod 32 is fixed to the installation end of a small motor 34. The output shaft of the small motor 34 is fixedly provided with a lead screw 35 threadedly arranged in the threaded hole in the middle of the lifting rod 32 through a coupling. A clamping plate 37 is fixedly arranged on the surface of the lifting rod 32 on one side of the clamping mechanism two 6. The clamping plate 37 and one end of the L-shaped plate 36 are the same in size.

[0033] A cross slot 15 is opened at the upper end of the detection box body 1. A cross slider 12 is horizontally slidably arranged in the cross slot 15. Both ends of the cross slider 12 protrude from the surface of the detection box body 1. The rotating assembly 5 is located at a position opposite to the clamping mechanism three 7 (combined with Figure 1 、 Figure 2 shown).

[0034] The rotating assembly 5 includes an installation sleeve 51 fixedly arranged at the lower end of the cross slider 12. A plurality of L-shaped rods 54 are longitudinally slidably arranged in the longitudinal slots on the surface of the prism 52. The sliders on the surface of the L-shaped rods 54 are slidably limited by the chutes in the longitudinal slots (shown in the figure for display). Different detection components are detachably inserted at the lower ends of the plurality of L-shaped rods 54. The detection components include, but are not limited to, a hard alloy ball cone indenter 13 and a pressing plate 14. Other L-shaped rods 54 have empty slots reserved at their lower ends. Users can install detection parts according to the detection needs. The hard alloy ball cone indenter 13 can detect the Mohs hardness of metals, and the pressing plate 14 detects the bending resistance of metals;

[0035] The installation ends of the hard alloy ball cone indenter 13 and the pressing plate 14 can be inserted into the empty slots at the bottom of the L-shaped rods 54 for easy disassembly and assembly. A pressure sensor is arranged between the pressing plate 14 and the bottom of the L-shaped rod 54. The pressure sensor is used to detect the downward pressure for reading.

[0036] The rotating assembly 5 further includes a servo motor 55 embedded in the lower opening of the mounting sleeve 51, and is threadedly fixed to the mounting holes on the surface of the servo motor 55 through screws penetrating the side wall of the mounting sleeve 51. The output shaft of the servo motor 55 is threadedly fixed to the middle of the prism 52. The upper end surface of the prism 52 is in contact with the lower end surface of the mounting sleeve 51 and can rotate, which can prevent the servo motor 55 from being damaged by force.

[0037] The top of the groove on the surface of the prism 52 is fixed to the fixed end of the second hydraulic rod 53 through screws. The telescopic end of the second hydraulic rod 53 is threadedly fixed to one end of the L-shaped rod 54, and the second hydraulic rod 53 is located in the groove on the surface of the prism 52.

[0038] Specifically, both sides of the lower ends of the two lower support plates 2 are fixed to the fixed ends of the second linear drive mechanism 9. The movable end of the second linear drive mechanism 9 is located in the gap between the two lower support plates 2 and is fixedly connected to the lower end of the moving plate 4, thereby driving the moving plate 4 to move. The lower end of the middle of the moving plate 4 is fixed to the fixed end of the first linear drive mechanism 8. A slideway 10 is provided on one side of the middle of the moving plate 4. The movable end of the first linear drive mechanism 8 movably penetrates the slideway 10 and is fixedly connected to the lower end of the fixed sleeve 31 of the third clamping mechanism 7. The upper end of the detection box 1 is fixed to the fixed end of the third linear drive mechanism 11. The movable end of the third linear drive mechanism 11 is fixedly connected to the cross slider 12. The movable end of the third linear drive mechanism 11 is preferably in an "L" shape.

[0039] Among them, the small motor 34 is preferably a reduction motor. Devices such as a compiler and a microcomputer are adapted to the servo motor 55. There are also devices such as a pump station for controlling the hydraulic rod, a motor controller, and a touch screen fixedly installed on one side of the detection box 1. Since they are not the main technologies, they will not be elaborated here. The above devices are connected through oil pipes and electric wires, and will not be detailed here because they are not the main technologies.

[0040] The third linear drive mechanism 11, the second linear drive mechanism 9, and the first linear drive mechanism 8 are all prior arts.

[0041] The principle and process of the present utility model:

[0042] When using this device, the user controls the operation of this device by operating the touch screen. There are various options in the touch screen, such as options for detecting the pressing strength and Mohs hardness. At this time, the movable end of the second linear drive mechanism 9 drives the moving plate 4 to move out of the detection box 1. Subsequently, the user inserts the equal-length metal to be tested into the L-shaped plates 36 and the clamping plates 37 of the first clamping mechanism 3 and the second clamping mechanism 6 respectively.

[0043] When detecting the pressing strength of the metal part;

[0044] Step 1. Subsequently, the small motor 34 is powered on and operates. The small motor 34 drives the lead screw 35 to rotate through the output shaft and the coupling, and then drives the L-shaped plate 36 to move downward, and clamps the metal part to be measured in cooperation with the clamping plate 37 to achieve the fixing effect. It should be noted that before clamping, the clamping plates 37 of the clamping mechanism 1 and the clamping mechanism 2 need to be in the same plane.

[0045] After the fixation is completed, the moving plate 4 moves back into the detection box body 1 and aligns the metal part to be measured with the pressure plate 14. During this process, the clamping mechanism 3 does not clamp the metal part to be measured.

[0046] Step 2. The movable end of the linear drive mechanism 3 drives the cross slider 12 to move in the cross groove 15, and then drives the rotating assembly 5 to move, moving the pressure plate 14 to the position to be detected of the metal part to be measured. Subsequently, the telescopic end of the hydraulic rod 2 extends to push the L-shaped rod 54 downward.

[0047] Until the pressure plate 14 contacts the surface of the metal part and continues to press downward. The set pressure sensor can detect the downward pressure in real time, or it can be detected through the oil pressure of the hydraulic rod itself, and the detection is carried out according to actual needs. The detection results will be displayed on the touch screen.

[0048] When detecting the bending resistance of the metal part to be measured:

[0049] The moving plate 4 moves out of the detection box body 1. It should be noted that at this time, the clamping mechanism 1 and the clamping mechanism 3 push the lifting rod 32 to rise under the push of the hydraulic rod 1. At the same time, the linear drive mechanism 1 is powered on and its movable end drives the clamping mechanism 3 to move and makes the clamping plate 37 of the clamping mechanism 3 move to the position of the clamping plate 37 of the clamping mechanism 1, so that the metal part to be measured can be inserted between the L-shaped plate 36 and the clamping plate 37. Then repeat the operation of "Step 1" to power on the small motor 34 to work, clamp and fix the metal part to be measured, and then move the moving plate 4 into the detection box body 1. At this time, repeat "Step 2" to move the pressure plate 14 to the free end of the metal part to be measured, so as to realize the detection of the bending resistance.

[0050] When performing the Mohs hardness test:

[0051] Repeat "Step 1". Subsequently, the microcomputer sends a signal to make the servo motor 55 work through the compiler. The output shaft of the servo motor 55 drives the prism 52 to rotate. The prism 52 is preferably a hexagonal prism, and the corresponding angle of each face is 60 degrees. The angle range of the output shaft rotation of the servo motor 55 can be designed through the angle range, and then the L-shaped rod 54 is rotated to make the carbide ball indenter 13 rotate to the upper end of the metal part to be measured. Then repeat "Step 2" to realize the detection of the Mohs hardness of the metal part.

[0052] It should be noted that three strength detection methods are listed in this case, including but not limited to, different detection heads can be installed at the lower end of the L-shaped rod 54, so it can be set according to needs.

[0053] With the above settings, this device can perform multiple strength detections on metal parts at one time, thereby increasing the detection types of the detection device, avoiding frequent replacement of the detection device for metal parts, and thus improving the detection efficiency.

[0054] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0055] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
