Abstract
Description
Technical Field
[0001] The invention relates to the technical field of hardness detection devices, in particular to a metal hardness detection device with an anti-deviation function. Background Art
[0002] Metal hardness is a mechanical property index that measures the hardness or softness of metal materials. It indicates the ability to resist deformation within a local volume on the metal surface. Metal hardness is not a simple physical concept, but a comprehensive index of mechanical properties such as material elasticity, plasticity, strength and toughness. The method for testing metal hardness often involves extruding the metal and observing the degree of deformation of the metal.
[0003] When metal hardness testing is performed by extruding metal, the extrusion position is not necessarily the center of gravity of the metal, which will cause the metal to shift. At the same time, when testing the extrusion of metal with higher hardness, the metal may also shift if the extrusion force is too large, resulting in inaccurate test results. Summary of the invention
[0004] The object of the present invention is to provide a metal hardness testing device with an anti-drift function to solve the problems raised in the prior art.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a metal hardness detection device with an anti-deviation function, comprising a detection base, a detection cylinder, a detection component, a weight sensing device and an anti-deviation device, the detection base is connected to the detection cylinder, the detection base and the detection component are tightly connected, the output end of the detection cylinder is connected to the weight sensing device, the detection base is connected to the anti-deviation device, and the output end of the detection cylinder is tightly connected to the weight sensing device.
[0006] The detection base is used as the main installation foundation for the installation and positioning of other devices. By placing metal on the weight sensing device, the detection cylinder outputs displacement to drive the weight sensing device upward until the metal contacts the detection component and stops. Then the weight sensing device and the anti-drift device adjust the center of gravity of the metal until the center of the weight sensing device is at the center of the metal gravity. Then the adjustment of the center of gravity stops. Then the detection cylinder outputs displacement upward to drive the weight sensing device upward until the metal and the detection component are clamped and fixed. Then the anti-drift device starts to prevent the metal from drifting. Then the detection cylinder continues to output displacement to start hardness detection of the metal. As the detection intensity increases, the output intensity of the anti-drift device gradually increases, and the anti-drift effect of the anti-drift device on the metal also increases.
[0007] Furthermore, the detection base is provided with fixing holes and mounting holes, there are four mounting holes, the detection cylinder is placed in the fixing holes, the detection cylinder and the fixing holes are fastened together, the anti-deviation device is placed in the four mounting holes, and the anti-deviation device is connected to the four mounting holes.
[0008] The fixing holes and the mounting holes serve as the installation basis. The fixing holes are mainly used to fix the detection cylinder, and the mounting holes are mainly used to fix the anti-deviation device.
[0009] Furthermore, the detection component includes a fixed column and a detection probe, the fixed column and the detection base are tightly connected, and the detection probe and the fixed column are tightly connected.
[0010] The fixed column is the main supporting device, which is mainly used to support and position the detection probe. The detection probe is a hardness detection tool, which detects the metal hardness by squeezing the metal deformation through the detection probe.
[0011] Furthermore, the weight sensing device includes an upper shell, a lower shell, a sensing component, a connecting rod and a sensing cylinder. There are several sensing components, and several sensing components are distributed at the inner edge of the upper shell. Several sensing components are respectively fastened to the upper shell, and several sensing components are fastened to the lower shell at one end away from the upper shell. The connecting rod is hinged to the upper shell, the connecting rod is fastened to the lower shell, the lower shell is fastened to the output end of the detection cylinder, and the sensing cylinder is fastened to the lower shell.
[0012] The upper shell and the lower shell serve as the main installation basis, and are mainly used for the installation and positioning of other components. When the center of gravity of the metal is not in the center position, the upper shell tilts to the heavier side through the connecting rod. After the upper shell tilts, the sensing component senses the tilt direction and tilt force, and then adjusts the center of gravity of the metal through the anti-drift device. After the center of gravity adjustment is completed, the anti-drift device begins to perform anti-drift treatment on the metal. At the same time, the sensing cylinder outputs the displacement outward until it abuts against the upper shell, forming support for the upper shell to prevent the upper shell from tilting and causing the metal to shift during subsequent hardness testing.
[0013] Furthermore, the induction component includes a first spring, a magnet, a support rod, an electromagnetic coil, a second spring and a coil housing. The first spring is tightly connected to the upper housing, one end of the first spring away from the upper housing is tightly connected to the magnet, the second spring is tightly connected to the magnet, one end of the second spring away from the magnet is tightly connected to the support rod, the electromagnetic coil is surrounded and placed in the coil housing, the electromagnetic coil and the coil housing are tightly connected, and the magnet is placed in the middle of the coil housing.
[0014] As the main supporting component, the support rod is mainly used to support and position other components. When the center of gravity of the metal is not in the center, the upper shell is offset, causing the first spring to move. The movement of the first spring drives the magnet to move. The magnet will allow the electromagnetic coil to cut the magnetic field of the magnet, causing a change in the magnetic flux and generating an induced current. According to the current intensity coefficient generated by the induction components in different positions, the anti-offset device makes corresponding adjustments to adjust the position of the center of gravity of the metal.
[0015] Furthermore, the anti-deviation device includes a lifting cylinder, a circular track and a fixing device. There are four lifting cylinders, which are placed in four mounting holes. The four lifting cylinders are respectively fastened to the connected mounting holes. The output ends of the four lifting cylinders are fastened to the circular track. There are four fixing devices, which are slidably connected to the circular track.
[0016] The lifting cylinder is used as a driving device, mainly used to send other components to the working position. The lifting cylinder outputs displacement to drive the circular track to move until the circular track moves to the working position. The fixing device moves to the corresponding position on the circular track and then begins to adjust and fix the position of the metal.
[0017] Furthermore, the annular track includes a track circular plate and an annular rod, the track circular plate is provided with four mounting grooves, the annular rod is placed in the four mounting grooves, the annular rod is fastened to the track circular plate, the mounting groove is connected to the fixing device, and the annular rod is connected to the fixing device.
[0018] The track circular plate serves as the main installation base for installing other components, and the ring rod serves as the main moving track to provide a moving base for the fixing device, allowing the fixing device to move along the ring rod.
[0019] Furthermore, the fixing device includes a fixed motor, a moving block, a moving cylinder and a fixed plate, the output end of the fixed motor is threadedly connected to the annular rod, the fixed motor is fastened to the moving block, the moving block is slidably connected to the mounting groove, the moving block is fastened to the moving cylinder, and the output end of the moving cylinder is fastened to the fixed plate.
[0020] The fixed motor is the main driving device and is mainly used to drive the moving block to move. When the center of gravity of the metal needs to be adjusted, the signal is detected and transmitted through the sensing component. The fixed motor outputs the torque to drive the moving block to move along the annular rod until the moving block moves to the specified position. The moving cylinder outputs the displacement to drive the fixed plate to move until the fixed plate stops outputting the displacement after the metal position is adjusted. Then the metal is fixed by the fixed plate to prevent the metal from shifting.
[0021] Compared with the prior art, the present invention has the following beneficial effects:
[0022] 1. A weight sensing device is provided. When the center of gravity of the metal is not at the center of the upper shell, the upper shell will be offset. Then multiple sensing components collect the offset electrical signals to find the center of gravity.
[0023] 2. An anti-deviation device is provided. The center of gravity is adjusted according to the center of gravity detected by the weight sensing device. After it is adjusted to the center of the upper shell, the metal extrusion test is started.

[0033] The detection base 1 is used as the main installation foundation for the installation and positioning of other devices. By placing metal on the weight sensing device 4, the detection cylinder 2 outputs displacement to drive the weight sensing device 4 to lift upward until the metal contacts the detection component 3 and stops. Then the weight sensing device 4 and the anti-drift device 5 adjust the center of gravity of the metal until the center of the weight sensing device 4 is at the center of the metal gravity. Then the adjustment of the center of gravity stops. Then the detection cylinder 2 outputs displacement upward to drive the weight sensing device 4 to move upward until the metal and the detection component 3 are clamped and fixed. Then the anti-drift device 5 starts to anti-drift the metal. Then the detection cylinder 2 continues to output displacement to start hardness detection of the metal. As the detection force increases, the output force of the anti-drift device 5 gradually increases, and the anti-drift effect of the anti-drift device 5 on the metal also increases.

[0035] The fixing hole 11 and the mounting hole 12 serve as a mounting basis. The fixing hole 11 is mainly used to fix the detection cylinder 2 , and the mounting hole 12 is mainly used to fix and connect the anti-deviation device 5 .
[0036] like Figure 1-Figure 3 As shown, the detection component 3 includes a fixing column 31 and a detection probe 32 . The fixing column 31 is tightly connected to the detection base 1 , and the detection probe 32 is tightly connected to the fixing column 31 .
[0037] The fixing column 31 is a main supporting device, mainly used for supporting and positioning the detection probe 32. The detection probe 32 is a hardness detection tool, and the metal hardness is detected by the detection probe 32 squeezing the metal to deform.
[0038] like Figure 1 , Figure 4 and Figure 6 As shown, the weight sensing device 4 includes an upper shell 41, a lower shell 42, a sensing component 43, a connecting rod 44 and a sensing cylinder 45. There are a plurality of sensing components 43, and the plurality of sensing components 43 are distributed at the inner edge of the upper shell 41. The plurality of sensing components 43 are respectively fastened to the upper shell 41, and the ends of the plurality of sensing components 43 away from the upper shell 41 are fastened to the lower shell 42. The connecting rod 44 is hinged to the upper shell 41, the connecting rod 44 is fastened to the lower shell 42, the lower shell 42 is fastened to the output end of the detection cylinder 2, and the sensing cylinder 45 is fastened to the lower shell 42.
[0039] The upper shell 41 and the lower shell 42 serve as the main installation basis, and are mainly used for the installation and positioning of other components. When the center of gravity of the metal is not in the center position, the upper shell 41 tilts to the heavier side through the connecting rod 44. After the upper shell 41 tilts, the sensing component 43 senses the tilt direction and tilt force, and then adjusts the center of gravity of the metal through the anti-drift device 5. After the center of gravity adjustment is completed, the anti-drift device 5 starts to perform anti-drift treatment on the metal. At the same time, the sensing cylinder 45 outputs the displacement outward until it abuts against the upper shell 41, thereby forming a support for the upper shell 41 to prevent the upper shell 41 from tilting during the subsequent hardness test and causing the metal to shift.
[0040] like Figure 4 and Figure 6 As shown, the induction component 43 includes a first spring 431, a magnet 432, a support rod 433, an electromagnetic coil 434, a second spring 435 and a coil shell 436.

[0041] The support rod 433 serves as the main supporting component and is mainly used to support and position other components. When the center of gravity of the metal is not in the center, the upper shell 41 is offset, causing the first spring 431 to move. The movement of the first spring 431 drives the magnet 432 to move. The magnet 432 allows the electromagnetic coil 434 to cut the magnetic field of the magnet 432, causing a change in the magnetic flux and generating an induced current. According to the current intensity coefficient generated by the induction component 43 at different positions, the anti-offset device 5 makes corresponding adjustments to adjust the position of the center of gravity of the metal.
[0042] like Figure 1-Figure 4 As shown, the anti-deviation device 5 includes a lifting cylinder 51, a circular track 52 and a fixing device 53. There are four lifting cylinders 51, and the four lifting cylinders 51 are placed in four mounting holes 12. The four lifting cylinders 51 are respectively fastened to the connected mounting holes 12, and the output ends of the four lifting cylinders 51 are fastened to the circular track 52. There are four fixing devices 53, and the four fixing devices 53 are slidably connected to the circular track 52.
[0043] The lifting cylinder 51 is used as a driving device, mainly used to send other components to the working position. The lifting cylinder 51 outputs displacement to drive the circular track 52 to move until the circular track 52 moves to the working position. The fixing device 53 moves to the corresponding position on the circular track 52 and then starts to adjust and fix the position of the metal.
[0044] like Figure 4 and Figure 5 As shown, the annular track 52 includes a track circular plate 521 and an annular rod 522. The track circular plate 521 is provided with four mounting grooves 5211. The annular rod 522 is placed in the four mounting grooves 5211. The annular rod 522 and the track circular plate 521 are fastened together. The mounting grooves 5211 are connected to the fixing device 53. The annular rod 522 and the fixing device 53 are connected.
[0045] The track circular plate 521 serves as the main installation base for installing other components, and the annular rod 522 serves as the main moving track to provide a moving base for the fixing device 53 , so that the fixing device 53 can move along the annular rod 522 .
[0046] like Figure 4 and Figure 5 As shown, the fixing device 53 includes a fixed motor 531, a moving block 532, a moving cylinder 533 and a fixed plate 534, the output end of the fixed motor 531 is threadedly connected to the annular rod 522, the fixed motor 531 and the moving block 532 are fastened together, the moving block 532 and the mounting groove 5211 are slidingly connected, the moving block 532 and the moving cylinder 533 are fastened together, and the output end of the moving cylinder 533 and the fixed plate 534 are fastened together.
[0047] The fixed motor 531 serves as the main driving device, and is mainly used to drive the moving block 532 to move. When the center of gravity of the metal needs to be adjusted, the sensing component 43 detects and transmits a signal, and the fixed motor 531 outputs a torque to drive the moving block 532 to move along the annular rod 522 until the moving block 532 moves to the specified position. The moving cylinder 533 outputs a displacement to drive the fixed plate 534 to move until the fixed plate 534 stops outputting the displacement after the metal position is adjusted, and then the metal is fixed by the fixed plate 534 to prevent the metal from shifting.
[0048] The working principle of the present invention is as follows: when it is necessary to perform hardness testing on metal, the metal is placed on the upper shell 41. When the center of gravity of the metal is not at the center position, the upper shell 41 tilts toward the heavier side through the connecting rod 44. After the upper shell 41 tilts, the upper shell 41 deviates, causing the first spring 431 to move. The movement of the first spring 431 drives the magnet 432 to move. The magnet 432 allows the electromagnetic coil 434 to cut the magnetic field of the magnet 432, causing a change in magnetic flux and generating an induced current. According to the electrical signal generated by the induction component 43 at different positions, the lifting cylinder 51 outputs a displacement to drive the annular track 52 to move. After the annular track 52 moves to the working position, the fixed motor 531 outputs a rotational torque to drive the moving The movable block 532 moves along the annular rod 522 until the movable block 532 moves to the specified position, and the movable cylinder 533 outputs displacement to drive the fixed plate 534 to move until the fixed plate 534 stops outputting displacement after adjusting the metal position, and then fixes the metal through the fixed plate 534. After the fixation is completed, the induction cylinder 45 outputs displacement outward until it abuts against the upper shell 41, forming a support for the upper shell 41 to prevent the upper shell 41 from tilting and causing the metal to shift during the subsequent hardness detection process, and then the detection cylinder 2 and the lifting cylinder 51 output displacement at the same time, and the hardness test is performed on the metal. As the detection intensity increases, the output intensity of the movable cylinder 533 gradually increases to ensure that the metal will not shift during the detection process.
