Description

Technical Field

[0001] The present application relates to the field of material testing, and in particular to a portable metallographic and micro-Vickers hardness integrated machine. Background Art

[0002] Vickers hardness tester can be used to measure the hardness of materials. The principle is that the diamond indenter presses the surface of the material for a specified time, and then the diagonal length of the indentation is measured, and the hardness is calculated according to the formula. Its test measurement range is wide and it can measure almost all metal materials currently used in industry. It is a common hardness measuring instrument.

[0003] Metallography: refers to the chemical composition of a metal or alloy and the physical and chemical states of the various components within the alloy. When a Vickers hardness tester is used to measure the hardness of a material, an indentation will be created on the metallographic structure after the Vickers hardness tester is pressed.

[0004] The existing Vickers hardness tester is only a desktop Vickers hardness tester, which needs to be placed indoors and installed horizontally on a stable foundation. It is very bulky and cannot be used on site. It can only be cut and taken to the laboratory for use. However, in reality, many objects that need to be tested cannot be cut, and the metallographic structure cannot be seen. That is, when it is necessary to perform Vickers hardness testing on materials outdoors, the existing Vickers hardness tester is inconvenient to use. Utility Model Content

[0005] The purpose of this application is to solve the problem that the Vickers hardness tester in the prior art is large in size, not easy to carry, cannot be used for on-site measurement, and cannot be used on the entire material, requiring cutting patterns. This application provides a portable metallographic and microscopic Vickers hardness integrated machine, characterized in that it includes a magnetic suction part, which can be adsorbed on the metal to be tested by magnetic force, and an electric lifting structure is provided on the magnetic suction part;

[0006] The electric lifting mechanism includes a controller and a movable slider, wherein the controller is fixedly mounted on the magnetic attraction portion, and the movable slider is driven by the controller to be lifted and lowered in a vertical direction;

[0007] The movable slider is provided with an observation device, a metallographic light source and a collection device. The observation device includes a converter. An eyepiece is provided on one side of the converter, and a pressing head and an objective lens are provided on the other side of the converter. The converter can convert the pressing head and the objective lens opposite to the eyepiece by rotation.

[0008] By adopting the above technical solution, the measuring instrument can be fixed on the metal surface to be measured using an electromagnet, the converter is adjusted so that the pressing head is opposite to the eyepiece, and then the electric lifting mechanism is turned on to lower the moving slider. The pressing head presses a groove on the metal, and then the metallographic structure and the indentation on the metallographic structure can be observed through the objective lens, and the acquisition device can be used to take pictures, measure the indentation, and calculate the hardness value of the metallographic structure.

[0009] The present application fixes the device on the metal surface to be tested by an electromagnet, uses an electric lifting mechanism to press out an indentation, and observes it, thereby calculating the hardness of the metal to be tested. The entire device is flexible and portable, can be fixed on the surface of different metals, does not require cutting out metal patterns, has little impact on the metal to be tested, is easy to carry, and can be used outdoors.

[0010] In one embodiment, the magnetic attraction portion includes a contact block and a support plate, wherein the contact block can be fixed on the metal to be measured by magnetic attraction; the support plate is fixedly arranged on the contact block and fixedly connected to the controller. The movable slider is slidably connected to the support plate, and a handle is arranged on the support plate, and the handle is arranged horizontally for taking the entire instrument.

[0011] By using the above technical solution, the magnetic part is divided into a contact block and a support plate, which facilitates the installation of the movable slider and provides support for the electric lifting mechanism, making the overall structure more stable and making the lifting of the movable slider more stable. A handle is provided on the support plate to facilitate the picking up of the entire device.

[0012] In one embodiment, an electromagnet and a magnetic switch are disposed inside the magnetic attraction portion. The electromagnet is fixedly disposed inside the magnetic attraction portion on a side away from the lifting device, and the magnetic switch is used to turn on and off the power supply of the electromagnet.

[0013] The above technical solution can reduce the influence of the electromagnet on the pressure of the lifting device.

[0014] The pressing head comprises a pressure sensor and a Vickers indenter. The pressure sensor is installed at the upper end of the Vickers indenter to measure the pressure of the Vickers indenter.

[0015] By placing the pressure sensor at the upper end of the Vickers indenter, the pressure applied by the Vickers indenter can be measured more accurately, making the measurement result more accurate.

[0016] The converter includes a fixed part and a rotating part, the fixed part is fixed on the slider, the rotating part is rotatably mounted on the fixed part, different objective lenses are mounted on the rotating part, and the rotating part has an objective lens hole, one side of the objective lens hole is opposite to the eyepiece, and the other side is opposite to the objective lens or a pressing head. The objective lens or pressing head opposite to the objective lens hole can be switched by rotating the rotating part.

[0017] By using the above technical solution, the purpose of quickly switching the pressing head and the objective lens and quickly switching the objective lenses of different magnifications can be achieved.

[0018] In one embodiment, an adjustable groove is provided on the side of the contact block that contacts the metal to be tested, so that the magnetic attraction portion can be more stably fixed on the tubular metal to be tested.

[0019] By adopting the above technical solution, when measuring tubular metal, the surface of the metal to be measured can be more stably adhered to and less prone to shaking. At the same time, by adjusting the adjustable groove, the contact plate is leveled so that the contact plate is parallel to the metal to be measured, ensuring that the pressing head is perpendicular to the metal to be measured when applying pressure.
