Description

Technical Field

[0001] The utility model relates to the technical field of hardness detection, in particular to a hard alloy detection device. Background Art

[0002] Cemented carbide is an alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy. In order to test the hardness of cemented carbide made of different material ratios, it is generally necessary to conduct hardness testing experiments on cemented carbide. Vickers hardness testing is a relatively common method for testing the hardness of cemented carbide. A diamond regular pyramid indenter is pressed into a horizontally placed flat and smooth surface under a specified load. After holding it for a period of time, the indentation surface area and average pressure are calculated to obtain the Vickers hardness value of the metal material.

[0003] In actual testing, the surface of the test sample is not always flat and smooth, so the sample needs to be polished. The current operation method is to take out the sample, polish it, observe it in the placement device, and then test it, which increases manpower and operation steps and reduces work efficiency. As the device does not have the function of polishing samples, we proposed a cemented carbide testing device. Utility Model Content

[0004] The utility model aims to solve the defect that the device in the prior art does not have the function of grinding samples, and proposes a hard alloy detection device.

[0006] A cemented carbide detection device comprises a base and a body fixedly mounted on the top of the base, an operation console is fixedly mounted on one side of the base, a positioning eyepiece is fixedly mounted on one side of the body, a turntable is rotatably connected to the bottom of the body, two objective lenses are fixedly connected to the bottom of the turntable, and a pressure head is fixedly connected to the bottom of the turntable. The cemented carbide detection device also comprises:

[0007] Lifting column: The lifting column is set on the top of the base. The lifting column is used to adjust the distance between the test sample and the turntable to facilitate sample testing;

[0008] A moving component is arranged on the top of the base, and is used to make the lifting column movable, so as to facilitate the grinding of the sample above the lifting column;

[0009] A clamping assembly, which is arranged on the top of the lifting column and is used to fix the test sample;

[0010] A grinding component is arranged on the top of the base, and is used for grinding the test sample.

[0011] In a possible design, the moving assembly includes a first slider, a through hole is opened in the base, the first slider is located inside the through hole and is slidably connected to both sides of the through hole, one side of the first slider is rotatably connected to a first screw rod, one end of the first screw rod passes through one side of the base and is threadedly connected to the base, one end of the first screw rod is fixedly connected to a handle, the top of the first slider is fixedly connected to a positioning block, the positioning block is threadedly connected to a lifting column, and an operating rod is fixedly sleeved on the lifting column.

[0012] In a possible design, the clamping assembly includes a loading platform, which is fixedly arranged on the top of the lifting column. A groove is provided on the top of the loading platform. Two second sliders are slidably connected to the inner walls on both sides of the groove. The two second sliders are rotatably connected to second screws. The two second screws respectively penetrate the inner walls on both sides of the loading platform and extend to the outside.

[0013] In a possible design, the grinding assembly includes a support column, the bottom of which is fixedly connected to the top of the base, the top of which is fixedly connected to the bottom of the body, a limiting ring is sleeved on the support column, a limiting screw is threadedly connected to the limiting ring, one side of the limiting ring is fixedly connected to a support plate, a motor is fixedly installed on the top of the support plate, the output end of the motor passes through the support plate and extends to the bottom of the support plate, and the output end of the motor is fixedly connected to a grinding disc.

[0014] In a possible design, a fixing block is fixedly connected to one side of the loading platform, and a level is fixedly installed on the top of the fixing block.

[0015] In a possible design, four support seats are threadedly connected to the top of the base at equal intervals, and the four support seats are used to fix the base and adjust the level of the entire device.

[0016] In the present application, the device is first placed on a flat platform, and then the spirit level on the loading platform is used to observe whether the device is in a horizontal position. If not, the support seat under the body is adjusted to make the body level. After the equipment is placed, the sample to be tested is placed in the groove of the loading platform. By screwing the two second screws on the loading platform, the two second sliders are clamped on the sample, and then the joystick is turned to slowly raise the lifting column until the sample on the loading platform is almost in contact with the objective lens, and the sample surface can be clearly observed through the positioning eyepiece, then stop and wait for detection.

[0017] When it is found through observation that the surface of the sample is not flat and the sample needs to be polished, turn the handle, and the handle drives the first slider to move to one side, so that the lifting column and the loading platform on the first slider also move to one side, and stop after the loading platform moves to the bottom of the polishing disk, and then turn the limit screw to allow the limit ring fixed to the support column to slide up and down to adjust the height of the polishing disk to fit the sample, and then start the motor through the operation console, and use the high-speed rotation of the motor output end to drive the polishing disk to rotate, and polish the sample. After polishing is completed, rotate the handle in the opposite direction to move the loading platform to the bottom of the objective lens, and observe whether the sample surface is flat again. If it is smooth and flat, rotate the turntable to align the pressure head on the turntable with the sample, and then operate the console buttons to test the sample.
