Description

Technical Field

[0001] The invention belongs to the technical field of electromechanical equipment automation and relates to an automatic detection system for bar hardness. Background Art

[0002] Bars are a common type of parts or parts processing blanks in the current machinery industry, especially metal cylindrical bars, which are the processing raw materials for key and important parts such as gears, transmission shafts, flanges, etc. in modern automobiles, high-speed railways, aircraft, and major weapon systems. Therefore, the metal properties of bars will directly determine the life and performance of large and advanced systems such as high-end intelligent equipment and weapons and equipment, and hardness is one of the key indicators of metal properties. Based on this, the process requirements for hardness testing will be proposed in the use of key parts raw materials. The purpose is to exclude blank materials that do not meet the mechanical performance requirements through hardness indicators, and further ensure the qualified rate of finished parts.

[0003] Although automatic hardness testers have been developed for hardness testing in the prior art, due to the low degree of automation and intelligence, most of the current bar hardness testing uses manual loading and unloading of materials to the automatic hardness tester, which has the following problems: 1) The labor intensity of operators is high, especially for medium and large metal bars. The weight of a single metal bar reaches more than 30kg, which puts great demands on the labor intensity of operators; 2) The loading and unloading status of the bars is inconsistent, resulting in inaccurate hardness testing, and unqualified bars are processed, resulting in waste of processing costs or defective products mixed into the products leaving the factory; 3) There are oxidized surfaces and impurities in the bar testing area that affect the test results of the hardness tester, and manual loading will result in different degrees of bar surface cleaning, missing cleaning, etc.

[0004] In the face of the above problems, relevant domestic institutions have also conducted research. Most of them use robots or manipulators combined with special fixtures to achieve material loading and unloading and transportation. For example, the Chinese patent "Bar Brinell Hardness Automatic Detection and Sorting Device" (Application Date: 2019.06.19; Application No.: CN201920925929.3; Announcement date: 2020.03.17; Publication number: CN210146482U) discloses that a conveying roller is arranged at the feeding end of the body, and a flattening device for grinding one end of the bar to be tested and a hardness detection device for measuring the hardness after grinding are arranged; a movable feeding manipulator is arranged on the roller, and the feeding manipulator moves above the roller under the control of the output signal of the control unit, grabs and conveys the bar to the accompanying fixture; the accompanying fixture clamps or releases the bar under the control of the output signal of the control unit, and can reciprocate between the flattening device and the hardness detection device under the action of the power device; the hardness detection device inputs the hardness data of the bar obtained in each test into the control unit; a feeding manipulator is also arranged to place the bar in the material box respectively. The method of clamping the bar by the manipulator and then loading and unloading reduces the efficiency of detection to a certain extent. Summary of the invention

[0036] The working process of the bar material hardness automatic detection system of the present invention is as follows: after the bar materials are manually added to the feeding bin 11, after the overall system start button is pressed, the control system issues a command, the bin closing cylinder 14 (the initial state is the retracted state) extends, the bin door 20 opens, and the bar materials roll along the slope under the action of gravity to the bar material receiving groove on the upper and lower movable plates 29 in the feeding mechanism 7. At this time, the bin closing cylinder 14 retracts, the bin door 20 closes, and the action state is fed back to the control system; After receiving the feedback of the retraction status of the silo closing cylinder 14, the control system issues a material replenishment command, and the upper and lower cylinders 40 extend to drive the upper and lower movable plates 29 to rise, so as to realize the vertical rise of the bar material. When the upper and lower cylinders 40 extend to the right position, the action status is fed back to the control system; After receiving the status feedback that the upper and lower cylinders 40 are in place, the control system issues a push command, and the push cylinder 33 (the initial state is the retracted state) extends, driving the push plate 36 to move outward, pushing the bar in the bar receiving groove outward, and then the push cylinder 33 retracts, and the status is fed back to the control system. At this time, the bar rolls along the slope of the material channel bottom plate 55 in the loading bin 8 to the inclined surface of the ejector plate 72 in the loading mechanism 9. After the control system issues a loading command, the loading cylinder 64 extends, driving the ejector plate 72 to move upward, lifting the bar on the inclined surface and dropping it into the V-shaped groove of the guide wheel 73 in the loading mechanism 9, and then the loading cylinder 64 retracts; The control system issues a cleaning command, and the cleaning cylinder 78 (the initial state is the retracted state) in the cleaning component 2 moves downward, and at the same time, the grinding head 79 rotates to drive the grinding wheel 81 to rotate, grinding the surface of the bar material, and the air nozzle 83 starts to blow air. After the grinding is completed, the cleaning cylinder 78 rises, the grinding head 79 stops rotating, the air nozzle 83 stops blowing air, and feedback is given to the control system; The control system issues a material moving command, the oblique extension cylinder 98 in the transverse feeding manipulator assembly 3 extends (the initial state is the retracted state), and the clamping push rod 105 is extended into the V-shaped groove of the guide wheel 73. The clamping cylinder 103 extends (the initial state is the retracted state) to clamp and center the bar material. Then, the transverse motor 93 rotates, driving the transverse reducer 94 to rotate and then realize the rotation of the transverse gear 106, realizing the movement of the entire mechanism, and pushing the bar material horizontally along the V-shaped groove of the guide wheel 73 to the V-shaped groove of the material receiving table of the hardness tester 4, and feeding back the in-position information to the control system; The control system issues a measurement command, the measuring head of the hardness tester 4 moves downward and measures the hardness, and feeds back the measured data to the control system. The control system classifies the hardness value of the bar material according to the data. If the measured value is within the first gear range, the control system issues a continue material movement command to transfer the bar material along the V-groove of the guide wheel 73 to the unloading guide plate 111 in the bar material unloading assembly 5, and then the control system issues a release command, the clamping cylinder 103 retracts, the oblique extension cylinder 98 retracts, and the transverse feeding manipulator assembly 3 returns to the initial state under the action of the transverse movement motor 93. At the same time, the warehouse cylinder 116 located at the first gear warehouse opening in the bar material unloading assembly 5 retracts (the initial state is extended, and the warehouse door is in a closed state at this time), the bar baffle 113 is flipped up, and the warehouse door is in an open state. The bar material slides into the warehouse opening under the action of gravity, completing the hardness detection and sorting of the bar material; in the subsequent process, the above working process is repeated.
