Description

Technical Field

[0001] This utility model relates to the field of physics, and in particular to a hardness testing device, especially a fully automatic sample hardness testing device. Background Technology

[0002] According to the standard GB / T231.1 Brinell hardness test standard for metallic materials, the sample is pressed with a specific force, and the hardness of the sample is calculated by measuring the indentation diameter, which serves as an important basis for judging whether the sample material is qualified. During the test, the pressing position on the sample and the initial height of the hardness testing head need to be adjusted according to the shape and height of the sample. In existing technology, an industrial camera is used to photograph the sample to obtain its diameter and surface characteristics. The sample height is measured manually, and the data is then transmitted to a controller. The controller adjusts the height of the hardness testing head according to the sample height, and then the sample is manually placed on the XY-axis slide mechanism of the hardness tester. The controller then plans the test points of the sample based on its diameter and surface characteristics, controls the XY-axis slide mechanism to adjust the initial position of the sample, and performs the test. After the test, the scrap sample is manually discarded into the waste disposal area. However, this test process involves a lot of manual operation, resulting in high labor intensity and low testing efficiency. Utility Model Content

[0020] The present invention will be further described below with reference to embodiments, but the present invention is not limited to these embodiments. Any similar variations using the present invention should be included in the protection scope of the present invention. The use of directional terms such as up, down, front, back, left, right, middle, inside, and outside in the present invention is only for the convenience of clear description and is not intended to limit the technical solution of the present invention.

[0021] like Figures 1-7 As shown, the present invention provides a fully automatic sample hardness testing device, including a photographic measuring device 1, a robot, a hardness tester 2, and a controller;

[0022] The shooting and measuring device 1 includes a base 3, on which a slide rail 4 and a cylinder 5 are provided. The slide rail 4 is parallel to the length direction of the base 3. A slider 6 is provided on the slide rail 4. A movable seat 7 is fixedly provided on the slider 6. The piston rod of the cylinder 5 is connected to the movable seat 7. A transparent plate 8 and a backlight source 9 are provided on the movable seat 7. The backlight source 9 is located below the transparent plate 8. A first mounting frame 10 and a second mounting frame 11 are fixedly provided on the base 3. The first mounting frame 10 and the second mounting frame 11 are spaced apart along the length direction of the base 3. An industrial camera 12 and a positive light source 13 are provided on the first mounting frame 10. The industrial camera 12 and the positive light source 13 are located above the movable seat 7. A contact measuring ruler 14 is provided on the second mounting frame 11. The contact measuring ruler 14 is located above the movable seat 7.

[0023] The robot is used to place the sample on the imaging and measuring device 1 and the hardness tester 2;

[0024] The hardness tester 2 includes a fixed base 15, on which an xy-axis slide mechanism 16, a hardness detection head 17 and a lifting drive device are provided. The hardness detection head 17 is located above the xy-axis slide mechanism 16, and the power output end of the lifting drive device is connected to the hardness detection head 17.

[0025] The cylinder 5, backlight source 9, industrial camera 12, positive light source 13, contact measuring ruler 14, control terminal of hardness tester 2, and output terminals of industrial camera 12 and contact measuring ruler 14 are all electrically connected to the controller.

[0026] The contact measuring scale 14 can use Keyence's GT2-A series contact displacement sensors, such as GT2-A32 and GT2-A50, where 32 and 50 represent the measuring range in mm. When the sensor measuring head extends downwards, it drives the internal scale to move synchronously. After touching the sample, it retracts. The controller calculates the height difference based on the distance between the sensor and the transparent plate 8 to obtain the height of the sample.

[0027] The hardness tester 2 can be a QATM (Aodemag) brand, model Q3000E. The xy-axis slide mechanism 16 includes two lead screw and nut drive mechanisms. One lead screw and nut drive mechanism drives a transverse slide 18 to move laterally, and the other lead screw and nut drive mechanism on the transverse slide 18 drives a longitudinal slide 19 to move longitudinally, thereby adjusting the xy-axis position of the sample. The lifting drive device can drive the hardness testing head 17 to move up and down.

[0028] The working principle of this utility model:

[0029] Taking a cylindrical sample as an example, during use, under the control of the controller, the robot vertically places the sample on the transparent plate 8. The piston rod of cylinder 5 extends, driving the moving seat 7 and the sample to move below the industrial camera 12. The lower backlight source 9 is turned on, and the upper front light source 13 is turned off. The industrial camera 12 takes a picture of the sample to obtain the sample's diameter (or the length and width of a square material, the outer and inner diameters of a circular sample, etc.). Then, the lower backlight source 9 is turned off, and the upper front light source 13 is turned on. The industrial camera 12 takes a picture of the sample to read the sample's surface features (such as whether there are test pits or defects on the sample surface). Next, the piston rod of cylinder 5 retracts, driving the moving seat 7 to move below the contact measuring scale 14. The sensor head of the contact measuring scale 14 extends, touches the sample surface, and then retracts. The controller calculates the height of the sample. Then, the controller... The controller adjusts the initial height of the hardness testing head 17 by controlling the lifting drive device of the hardness tester 2 according to the height of the sample. Then, the robot transfers the sample from the transparent plate 8 to the longitudinal slide 19 of the hardness tester 2. The controller then plans the hardness test points of the sample according to the surface characteristics and diameter of the sample (for example, if the sample diameter is Φ50, four points are marked on the Φ30 diameter ring; if the sample diameter is Φ30, four points are marked on the Φ15 diameter ring, while avoiding surface defects). After planning, the controller controls the xy-axis slide mechanism 16 to adjust the initial position of the sample. Then, the hardness testing head 17 moves down to perform hardness testing. After completing the test of one test point, the hardness testing head 17 rises, and the xy-axis slide mechanism 16 adjusts the position of the sample to perform the test of the next test point. After all test points are completed, the robot transports the sample to the scrap position.

[0030] This invention relates to a fully automatic sample hardness testing device. The device uses a robot and cylinder 5 to transport the sample and a contact measuring ruler 14 to measure the height of the sample, thereby greatly reducing manual operation, alleviating labor intensity, and improving testing efficiency.

[0031] Furthermore, the transparent plate 8 is made of acrylic sheet.

[0032] Furthermore, the controller is a PLC.

[0033] Specifically, the specific structures and principles of the robot, hardness tester 2, controller, cylinder 5, industrial camera 12, and contact measuring ruler 14 in this utility model, as well as other aspects not described in detail, all adopt well-known solutions in the prior art, which are already understood by those skilled in the art and will not be elaborated here. The computer programs used in this utility model are all prior art, and this utility model does not involve any improvement to the computer programs.
