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] Bar stock is a common component or rough material used in the machinery industry. Cylindrical metal bar stock, in particular, is the raw material used to manufacture critical components such as gears, drive shafts, and flanges in modern automobiles, high-speed trains, aircraft, and major weapon systems. Therefore, the metal properties of bar stock directly determine the lifespan and performance of large, advanced systems like high-end intelligent equipment and weaponry. Hardness is a key metal property indicator. Consequently, hardness testing is a process requirement for critical component raw materials. This is to eliminate rough material that doesn't meet mechanical property requirements based on the hardness index, further ensuring the pass rate of finished parts.

[0003] Although automatic hardness testers have been developed for hardness testing in the existing technology, due to the low degree of automation and intelligence, most of the current bar hardness testing uses manual loading and unloading to the automatic hardness tester, which has the following problems: 1) The labor intensity of the operator 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 the operator; 2) The loading and unloading status of the bar 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) The presence of oxidized surfaces, impurities, etc. in the bar testing area affects the test results of the hardness tester, and manual loading will result in different degrees of bar surface cleaning, missed cleaning, etc.

[0004] In response to 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 "Automatic detection and sorting device for bar Brinell hardness" (application date: 2019.06.19; application number: CN201920925929.3; Announcement Date: 2020.03.17; Publication Number: CN210146482U) discloses a conveyor roller conveyor at the feed end of the main body, equipped with a flattening device for grinding one end of the bar to be tested and a hardness testing device for measuring the hardness after grinding. A movable feeding robot is installed above the roller conveyor. Under the control of the output signal of the control unit, the feeding robot moves above the roller conveyor, grabs the bar, and conveys the bar to the accompanying clamp. The accompanying clamp, under the control of the output signal of the control unit, clamps or releases the bar and can reciprocate between the flattening device and the hardness testing device under the action of a power device. The hardness testing device inputs the hardness data of the bar obtained from each test into the control unit. A feeding robot is also provided to place the bar into a material box. The method of using the robot to clamp the bar and then load and unload the bar reduces the efficiency of the test to a certain extent. Summary of the Invention

[0064] like Figure 17 As shown, the control system 6 includes an upper computer control system, which is electrically connected to a lower computer controller, which is installed in the electric control box door 24.

[0065] The working process of the automatic bar hardness detection system of the present invention is as follows: after the bars are manually added to the feeding bin 11, the overall system start button is pressed, and the control system issues a command, the bin closing cylinder 14 (initial state is retracted) extends, the bin door 20 opens, and the bars roll along the slope under the action of gravity into the bar receiving grooves 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 operation status is fed back to the control system;

[0066] After receiving the feedback on the retraction status of the silo closing cylinder 14, the control system issues a refilling command, and the upper and lower cylinders 40 extend, driving the upper and lower movable plates 29 to rise, thereby realizing the vertical rise of the bar material. When the upper and lower cylinders 40 are extended to their full length, the action status is fed back to the control system.

[0067] After the control system receives the feedback that the upper and lower cylinders 40 are in the extended position, it issues a pushing instruction. The pushing cylinder 33 (the initial state is retracted) extends, driving the pushing plate 36 to move outward, pushing the bar in the bar receiving groove outward, and then the pushing cylinder 33 retracts and feeds back the state 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 the loading instruction, 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;

[0068] The control system issues a cleaning command, and the cleaning cylinder 78 (initially retracted) in the cleaning assembly 2 moves downward, while the grinding head 79 rotates, driving the grinding wheel 81 to rotate, grinding the surface of the bar, and the air nozzle 83 starts blowing air. After grinding is completed, the cleaning cylinder 78 rises, the grinding head 79 stops rotating, the air nozzle 83 stops blowing air, and feedback is sent to the control system.

[0069] The control system issues a material movement command, and the oblique extension cylinder 98 in the transverse feeding manipulator assembly 3 extends (the initial state is retracted), and the clamping push rod 105 extends into the V-shaped groove of the guide wheel 73. The clamping cylinder 103 extends (the initial state is retracted) 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 feedback the position information to the control system;

[0070] The control system issues a measurement instruction, 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 instruction, and moves 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. Then the control system issues a release instruction, the clamping cylinder 103 retracts, the oblique extension cylinder 98 retracts, and the horizontal feeding manipulator assembly 3 returns to the initial state under the action of the horizontal movement motor 93. At the same time, the warehouse cylinder 116 located at the first gear warehouse mouth 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 material baffle 113 flips up, and the warehouse door is in an open state. The bar material slides into the warehouse mouth 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.
