Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of Brinell hardness detection, and particularly relates to a Brinell hardness automatic detection system and a detection method thereof. BACKGROUND

[0002] The Brinell hardness test is a kind of indentation hardness test method mainly for metal materials. A certain load is applied to the metal material by a pressure head, and then the diameter of the indentation left by the pressure head on the metal material is measured by a measuring device, and the Brinell hardness value of the metal material is calculated according to the indentation area and the test force.

[0003] The current Brinell hardness detection method is mainly suitable for metal materials with simple and regular shapes. For example, the patent CN210146482U rod Brinell hardness automatic detection and sorting device mainly relates to rod Brinell hardness automatic detection and sorting. A conveying roller is arranged at the feeding end of the device, a grinding device is arranged to grind one end of the rod to be detected, and a hardness detection device is arranged to measure the hardness after grinding. A movable feeding manipulator is arranged above the roller. The feeding manipulator moves above the roller under the control of the output signal of the control unit, grabs and conveys the rod to a profile clamp. The profile clamp clamps or releases the rod under the control of the output signal of the control unit, and can move back and forth between the grinding device and the hardness detection device under the action of a power device. The hardness data of the rod detected by the hardness detection device each time is input into the control unit. A discharging manipulator is also arranged to place the rods in the bins. This device is suitable for products with simple and regular shapes, and special clamps are needed to achieve the detection. Therefore, it cannot be applied to the automatic detection of parts with complex structures.

[0004] Blade parts play an important role in mechanical manufacturing. The shape of blade parts is often very complex, including various curved surfaces, twists and bending structures, and the size and material of the blade parts vary greatly. These complexities not only increase the processing difficulty, but also put higher requirements on the hardness detection of the blade parts. In addition, the working environment of the blade parts is usually harsh, which puts high requirements on the hardness and wear resistance of the blade parts. However, there is currently no automatic detection method for parts with complex structures similar to blade parts. SUMMARY

At the same time, empty turnover boxes 2-2 are placed on the unqualified collecting table 7-1 and the qualified product collecting table 7-2 to store the detected parts.

[0051] 2. Feeding. The integrated unit 1 controls the movement of the conveying belt 2-3, and the turnover boxes 2-2 containing the parts to be detected are moved to the position of the optical sensor I 2-5 under the driving of the conveying belt 2-3 and the guidance of the positioning plate 2-7. After the optical sensor I 2-5 senses the turnover boxes 2-2, the integrated unit 1 controls the conveying belt 2-3 to stop running, and the clamping device 2-6 clamps the turnover boxes 2-2 containing the parts to be detected.

The integrated unit 1 stores the marking data and the quick-change clamp I 3-2 resets.

[0054] 4. Polishing. The integrated unit 1 controls the mechanical arm I 4-2 to transfer the parts to be inspected after marking to the quick-change clamp II 5-1, the quick-change clamp II 5-1 clamps the parts to be inspected and sends them to the measuring sensor 5-2 for thickness measurement. After the measurement is completed, the integrated unit 1 determines the safe idle stroke of the polishing device 5-3 according to the measurement result. Then, the integrated unit 1 controls the quick-change clamp II 5-1 to send the parts to be inspected to the position of the polishing device 5-3 for polishing according to the set polishing amount. After polishing is completed, the quick-change clamp II 5-1 resets, and the integrated unit 1 controls the mechanical arm I 4-2 to place the polished parts to be inspected at the transfer station 4.

[0055] 5. Brinell hardness detection.

The integrated unit 1 controls the rotating mechanism to rotate the parts to be inspected to the hardness tester 6-3 station. After the optical sensor II 6-4 senses the parts to be inspected, the integrated unit 1 controls the lifting mechanism to drive the quick-change clamp III 6-5 to lift. The quick-change clamp III 6-5 is lifted to the indentation position, the hardness tester 6-3 is started to press the indentation, and after the indentation is completed, the lifting mechanism drives the quick-change clamp III 6-5 to reset. The rotating mechanism rotates again to send the parts to be inspected to the indentation measuring device 6-2 station. The indentation measuring device 6-2 moves to contact the parts to be inspected for measurement. According to the acceptance rules, it is judged whether the parts to be inspected are qualified. The integrated unit 1 collects and stores the measurement results of the indentation measuring device 6-2.

[0056] 6. The empty turnover box 2-2 is transported to the qualified product collection platform 7-2 by the conveyor belt 2-3. After the optical sensor Ⅲ 7-4 detects that the empty turnover box 2-2 has reached the designated position, the integrated unit 1 controls the robotic arm Ⅱ 4-3 to transfer the qualified parts to be inspected into the empty turnover box 2-2 according to the feedback data of the optical sensor Ⅲ 7-4.

[0057] Under the control of integrated unit 1, the unqualified parts to be inspected are sent by robotic arm II 4-3 to the turnover box 2-2 of the unqualified collection table 7-1 for storage.
