Detailed implementation manners
[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0018] Please refer to Figures 1-4 , a toughness detection device for brass strips, including a workbench 1, and further including: A detection assembly, the detection assembly includes a detection box 2, an adjustment cover 3, a detector 4, a spacing adjustment member and a connecting wire 5. A detection cavity is provided in the detection box 2. An adjustment cover 3 for closing the detection cavity is provided on the detection box 2. A detector 4 is provided on the adjustment cover 3. The detection box 2 is arranged on the workbench 1; At first, an insulating medium is filled in the detection box 2. The insulating medium can be selected as mineral insulating oil (mainly derived from petroleum refining, with good chemical stability, capable of remaining stable within a relatively wide temperature range (usually -40°C - 105°C), meeting the requirements for open use in most conventional environments. It has good insulation performance and a relatively high breakdown voltage, which can effectively isolate the charged components and prevent current leakage), or silicone oil can also be used. Silicone oil is famous for its excellent chemical stability, heat resistance and cold resistance. Its operating temperature range is extremely wide, generally being able to work stably between -50°C - 200°C, suitable for open use in a variety of extreme temperature environments. The insulation performance of silicone oil is excellent, and it can effectively prevent current leakage in a high-voltage environment, and the transparency of silicone oil is higher. Therefore, as a preferred example of this embodiment, the adjustment cover 3 is not covered on the detection box 2, but is located above the detection box 2. The piece to be detected is placed at the acting end of the spacing adjustment member, so that the detector 4, the connecting member and the piece to be detected form a circuit, and then the adjustment cover 3 is covered on the detection box 2.
[0019] In this embodiment, the spacing adjustment assembly includes a lifter 6, a back plate 7, side plates 8, a front plate 9, a lifting plate 10, a base 11, a limiting rod 12, a contact 13 and a slider 14. The output end of the lifter 6 penetrates through the adjustment cover 3 and is connected to the top wall of the lifting plate 10. The upper part of the back plate 7 is connected to the adjustment cover 3. The side plates 8 are symmetrically arranged on both sides of the front of the back plate 7. The front plate 9 is arranged on the front of the two side plates 8. The lifting plate 10 is arranged between the back plate 7 and the front plate 9. Oblique holes are symmetrically arranged on the left and right sides of the lifting plate 10. Horizontal holes adapted to the oblique holes are arranged on the front plate 9. The base 11 is L-shaped. The limiting rod 12 penetrating through the corresponding oblique holes and horizontal holes is arranged on the back side of the base 11. The contact 13 connected to one end of the connecting wire 5 is arranged on the base 11. The other end of the connecting wire 5 penetrates through the base 11 and the adjustment cover 3 and is connected to the detector 4. A fastener for connecting the end of the material to the contact 13 is also arranged on the base 11. The detector 4 is arranged on the periphery of the lifter 6. The slider 14 is also arranged on the back side of the base 11. Guide grooves slidably connected to the slider 14 are symmetrically arranged on the left and right sides of the front of the front plate 9; Place the workpiece to be detected (brass strip) on the base 11 and fix it with a fastener, so that the detector 4, the connecting wire 5, the contact 13, the brass strip, the contact 13, and the connecting wire 5 are connected in series to form a loop. Initially, when the brass strip is assembled, the lifter 6 is in a contracted state. The lifter 6 uses a cylinder. The back plate 7 is connected to the adjustment cover 3. The side plates 8 on both sides of the back plate 7 stably support the front plate 9. At this time, the lifting plate 10 is at the higher end, and the spacing between the two bases 11 is the largest. When the brass strip is immersed in the insulating medium, the lifter 6 extends, and the lifting plate 10 descends. Under the limitation of the oblique holes and the horizontal holes, the base 11 cooperates with the slider 14 to slide on the front of the front plate 9. The two bases 11 move towards each other, and the brass strip is bent. The lifter 6 reciprocates, and the brass strip is repeatedly bent. When the brass strip breaks, the insulating medium extinguishes the arc. At this time, the loop formed by the detector 4, the connecting wire 5, the contact 13, and the brass strip is short-circuited, and the lifter 6 stops moving. The detector 4 can count the number of reciprocating movements of the lifter 6. The detector 4 includes a display screen, a warning device (which can use sound or optoelectronic changes for prompting), a storage battery, a counter, and a data storage device, which will not be elaborated here. During the lifting process of the lifting plate 10, the guide rod 35 penetrating through the adjustment cover 3 ensures the stability of the lifting of the lifting plate 10; During the actual use process, a temperature adjustment assembly for adjusting the temperature of the insulating medium is further arranged on the detection box 2, so as to adjust the temperature of the insulating medium, and further adjust the temperature of the brass strip, and perform toughness detection at different temperatures.
[0020] During actual use, it is necessary to stably adjust the height of the adjusting cover 3. To this end, the height adjustment assembly includes a motor 15, a housing 16, a worm gear 17, a worm 18, a sliding frame 19, a first screw 20, and a hanging ear 21. Sliding frames 19 are symmetrically arranged on the left and right sides above the detection box 2. A first chute is provided at one end of the sliding frame 19 close to the detection box 2. The first screw 20 is rotatably arranged in the first chute. A housing 16 is also provided on the two sliding frames 19. A worm 18 and two worm gears 17 are arranged in the housing 16. The worm 18 meshes with the two worm gears 17. The output end of the motor 15 penetrates through the housing 16 and is connected to the worm 18. The upper part of the first screw 20 penetrates through the sliding frame 19 and the housing 16 and is connected to the center of the worm gear 17. Hanging ears 21 extending into the first chute are arranged on the left and right sides of the adjusting cover 3. The hanging ears 21 are threadedly connected to the first screw 20. The housing 16 is arranged on the periphery of the detector 4 and the lifter 6. Notches adapted to the hanging ears 21 are provided on the left and right sides above the detection box 2; Start the motor 15 of the height adjustment assembly. The output end of the motor 15 drives the worm 18 to rotate. The worm 18 drives the two worm gears 17 to rotate synchronously. The worm gears 17 drive the first screw 20 connected to their centers to rotate. Since the hanging ears 21 on the left and right sides of the adjusting cover 3 are threadedly connected to the first screw 20, the hanging ears 21 move up and down in the first chute as the screw rotates, thereby driving the adjusting cover 3 and the entire detection assembly to rise or fall, achieving precise adjustment of the height of the workpiece to be detected. In this embodiment, the motor 15 uses a servo motor 15 with precise control.
[0021] During actual use, the fastener includes a second screw 22, a handle 23, and a pressing plate 24. A second chute is further provided on the side wall of the base 11. The second screw 22 is rotatably arranged in the second chute. The upper part of the second screw 22 penetrates through the base 11 and is connected to the handle 23. The pressing plate 24 is T-shaped. One end of the pressing plate 24 extends into the second chute and is threadedly connected to the second screw 22. The other end of the pressing plate 24 is arranged above the contact point 13. A friction pad 25 is further provided below the other end of the pressing plate 24. Friction lines 26 are also provided on the handle 23. By rotating the handle 23 with the friction lines 26, the handle 23 drives the second screw 22 to rotate. The pressing plate 24 can move up and down under the limitation of the second chute and the drive of the second screw 22. When it is necessary to fix the brass strip, the pressing plate 24 drives the friction pad 25 to move downward to stably clamp the end of the brass strip.
[0022] During actual use, to facilitate the downward bending of the brass strip and ensure its full immersion in the insulating medium, the two sets of inclined holes are in an "eight" shape. A direction-adjusting rod 27 is further provided on the front surface of the lifting plate 10. The direction-adjusting rod 27 is arranged between the two sets of inclined holes. When the detected part is in a horizontal state, the direction-adjusting rod 27 is located above the detected part. A direction-adjusting groove adapted to the direction-adjusting rod 27 is further provided on the front plate 9. After the lifter 6 extends, the lifting plate 10 drives the adjusting rod to move downward. The adjusting rod initially applies a downward force to the middle part of the brass strip. Due to the self-gravity of the brass strip and the movement of the two sets of bases 11, the brass strip is stably bent downward.
[0023] In this embodiment, the temperature adjustment component includes a controller 28, a heating plate 29, a cold circulation box 30, a cold circulation plate 31, and a liquid supply pump 32. A controller 28 connected to the heating plate 29, the cold circulation box 30, and the liquid supply pump 32 is provided on the front surface of the detection box 2. The heating plates 29 are further provided on the left and right sides of the detection cavity. The cold circulation plate 31 is provided on the bottom wall of the detection cavity. The cold circulation box 30 is provided on the back side of the detection box 2. One end of the liquid supply pump 32 is connected to one end of the cold circulation box 30. The input end of the cold circulation plate 31 penetrates through the detection box 2 and is connected to the other end of the liquid supply pump 32. The output end of the cold circulation plate 31 is connected to the other end of the cold circulation box 30. The direction-adjusting rod 27, the friction pad 25, the base 11, and the cold circulation plate 31 are all made of insulating materials. The temperature adjustment component further includes a temperature sensor probe 33. The temperature sensor probe 33 penetrating through the detection box 2 is provided on the back side of the controller 28. When the temperature adjustment component starts to work, the temperature sensor probe 33 monitors the temperature of the insulating medium in the detection cavity in real time and feeds the data back to the controller 28. If it is necessary to increase the temperature, the controller 28 controls the heating plate 29 to work and heats the insulating medium. If it is necessary to decrease the temperature, the controller 28 starts the liquid supply pump 32 to pump the coolant in the cold circulation box 30 into the cold circulation plate 31. The coolant circulates in the cold circulation plate 31, absorbs the heat of the insulating medium, and then flows back to the cold circulation box 30. (During this process, the brass strip is immersed in the insulating medium and is in a "water bath" state), realizing precise adjustment of the temperature of the insulating medium and the detected part and simulating different usage temperature conditions.
[0024] In this embodiment, reinforcing ribs 34 connected to the bottom wall of the sliding frame 19 are further provided on the left and right sides of the detection box 2 to ensure stable support for the sliding frame 19.
[0025] During actual use, legs 36 are further provided at the four corners below the workbench 1. A drain pipe 37 passing through the workbench 1 is further provided below the detection box 2. A switch valve 38 is further provided on the drain pipe 37. The switch valve 38 is arranged below the workbench 1. The legs 36 provide stable support for the workbench 1. When it is necessary to replace the insulating medium, by opening and closing the switch valve 38, the output of the drain pipe 37 can be controlled to discharge the insulating medium mixed with impurities. After cleaning the detection cavity, new insulating medium is replenished to facilitate the detection of subsequent materials. It should be noted here that when assembling the brass strip, the detector 4 is in a power-off state, and at this time, the adjustment cover 3 is in a relatively high position, and there will be no movement interference among the cover body 16, the lifter 6, the guide rod 35 and the detector 4. At this time, the base 11 is above the insulating medium. Only when the adjustment cover 3 closes the detection cavity, the detector 4 is controlled to be powered on to perform a toughness test on the brass strip.
