DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] like Figures 1 to 3 As shown, a hardware accessories detection screening machine described in an embodiment of the present invention comprises a screening conveyor 1; both sides of the ends of the screening conveyor 1 are rotatably connected with a rotating shaft 11 through a torsion spring; a No. 1 guide plate 12 is fixedly connected to the outside of the two rotating shafts 11; a limiting component is provided at the end of the screening conveyor 1, and the limiting component is used to limit the hardware accessories; a detection mechanism is provided at the end of the screening conveyor 1, and the detection mechanism is used to detect hardware accessories; when detecting and screening the hardware accessories gear, first adjust the guide angle of the No. 1 guide plate 12, and the two sets of rotating shafts 11 are symmetrically arranged with the No. 1 guide plate 12, and the spacing between the two No. 1 guide plates 12 reserves the diameter of a gear, and multiple gears are placed on the screening conveyor 1 for transportation. If the gear When the gears are placed on the screening conveyor 1 and are offset for transportation, which affects the detection of the detection mechanism, the two No. 1 guide plates 12 correspond to the conveying trajectory of the guide gears, and the limit assembly assists the conveying trajectory of the limit gears, so that the gears can be guided and transported to the detection mechanism one by one for multiple inspections at the same time, and finally the defective products are screened out, thereby improving the detection and screening efficiency of the gears. At the same time, when the gears are piled up on the screening conveyor 1, the extrusion force of the stacked gears is greater than the torsion of the torsion spring, and the No. 1 guide plate 12 can be squeezed to cooperate with the rotation angle of the rotating shaft 11 to expand the distance between the two No. 1 guide plates 12. The torsion spring contracts and is stressed, and is guided for the second time when the stacked gears reach the limit assembly, so that the gears return to the normal conveying trajectory, playing the role of adaptive conveying gears.

[0029] The limiting assembly includes a fixed block 2, a sliding frame 21, a limiting hole 22, an insert rod 23, a first limiting plate 24 and a second limiting plate 25; the two fixed blocks 2 are respectively fixedly connected to both sides of the end of the screening conveyor 1; the sliding frame 21 is slidably connected to the inner wall of the fixed block 2; a plurality of limiting holes 22 are provided at the top of the sliding frame 21; the insert rod 23 is inserted into the limiting hole 22, the insert rod 23 passes through the fixed block 2, and a first elastic member is connected between the insert rod 23 and the fixed block 2; the first limiting plate 24 and the second limiting plate 25 are respectively fixedly connected to the bottom ends of the two sliding frames 21, and the first limiting plate 24 and the second limiting plate 25 are relatively Setting: When the gear is conveyed for inspection, first slide the sliding frame 21 on the fixed block 2, adjust the distance between the No. 1 limit plate 24 and the No. 2 limit plate 25, adjust the distance to be consistent with the distance between the two No. 1 guide plates 12, and use the No. 1 elastic member to drive the insertion rod 23 to penetrate the fixed block 2 and limit the limit hole 22. When the gear is conveyed to the No. 1 limit plate 24 and the No. 2 limit plate 25, the No. 1 limit plate 24 and the No. 2 limit plate 25 can limit the output trajectory of the gear, so that the gear is conveyed to the detection mechanism for multiple detection and screening. At the same time, the front end of the No. 1 limit plate 24 and the No. 2 limit plate 25 can guide the gear for conveying.

[0030] like Figure 1 to Figure 2 As shown, the detection mechanism includes a fixed frame 3, a track frame 31, a monitor 32, an electric cylinder 33 and a matching component; a plurality of the fixed frames 3 are fixedly connected to the end of the screening conveyor 1; the track frame 31 is fixedly connected to the outside of a plurality of fixed frames 3; the monitor 32 is installed at the bottom end of the track frame 31; a plurality of the electric cylinders 33 are slidably connected to the bottom end of the track frame 31 through an electric slider; the matching component is arranged on the inner wall of the first limit plate 24, and the matching component is used for the meshing detection of the hardware accessories; when the gear conveying is detected, the fixed frame The support track frame 31 is fixed above the No. 1 limit plate 24 and the No. 2 limit plate 25. After the gear is transported to the lower position of the track frame 31, the output end of the single electric cylinder 33 extends and presses the upper part of the single gear. The electric slider drives the gear at the bottom of the electric cylinder 33 to follow the screening conveyor 1 for synchronous transportation. The matching components detect the meshing of the hardware accessories, and the monitor 32 synchronously detects the meshing degree and the defective condition of the conveying gear. After the defective products are detected, the personnel can be notified to take them out, which plays the role of synchronous multiple detection and screening of the gears.

[0031] like Figures 1 to 3As shown, the mating component includes a connecting plate 4, a correction tooth 41 and a test tooth 42; the connecting plate 4 is rotatably connected to the inner wall of the No. 1 limit plate 24, and the connecting plate 4 is located below the monitor 32; the correction tooth 41 is fixed to the outside of the connecting plate 4; multiple test teeth 42 are fixed to the outside of the connecting plate 4 away from the correction tooth 41; when the gear is meshing detected, the connecting plate 4 is installed on the inner wall of the No. 1 limit plate 24, and a single gear is transported to the connecting plate 4. The correction tooth 41 first matches the gear correction angle, which makes it easier for subsequent gears to mesh with multiple test teeth 42 for easier detection. When the gear reaches the multiple test teeth 42, the gear meshes with the multiple test teeth 42, and the monitor 32 monitors the meshing degree and the defective state of the gear in real time, so as to realize the function of gear meshing detection, and can remove defective products when they are detected.

[0032] A servo motor 5 is fixedly connected to the inner wall of the No. 1 limit plate 24, and the output end of the servo motor 5 is fixedly connected to the outside of the connecting plate 4; a guide groove is opened in the No. 2 limit plate 25 near the connecting plate 4; a No. 2 guide plate 51 is fixedly connected to the outside of the No. 2 limit plate 25 and located at the guide groove; when multiple test teeth 42 are used to detect the meshing of gears, if the meshing degree of multiple test teeth 42 and the gears is unqualified, the output end of the servo motor 5 drives the connecting plate 4 to rotate an angle, and the connecting plate 4 assists in guiding the gears. As the screening conveyor 1 continues to transport the gears, the gears are transported through the guide groove, and are assisted by the No. 2 guide plate 51 to another channel for conveying and unloading. The servo motor 5 drives the connecting plate 4 to rotate and reset again, thereby removing unqualified gears.

[0033] like Figures 1 to 3 , Figure 5 As shown, the inner walls of the No. 1 limit plate 24 and the No. 2 limit plate 25 are symmetrically and slidably connected with a spacer plate 6; the outside of the spacer plate 6 is fixedly connected with a plurality of No. 2 elastic members 61; when the gears are conveyed for detection and screening, multiple gears are placed closely on the screening conveyor 1 for conveying, which is easy to affect the detection effect. Two spacer plates 6 are symmetrically installed inside the No. 1 limit plate 24 and the No. 2 limit plate 25. The spacer plate 6 can block multiple gears. When the output end of the electric cylinder 33 is pressed on the frontmost gear, the frontmost gear slides and squeezes the spacer plate 6 to retract into the No. 1 limit plate 24. The No. 2 elastic member 61 contracts and is stressed. The pressed gear is sent for engagement detection, and then a gear close to the spacer plate 6 will be conveyed to the interception position of the previous gear, waiting for the next electric cylinder 33, thereby playing the role of intermittently conveying and detecting the gears one by one.

[0034] like Figures 1 to 4As shown, the bottom end of the track frame 31 is fixedly connected to a fixed plate 7; the bottom end of the fixed plate 7 is slidably connected to a sliding rod 71 through a No. 3 elastic member; the bottom end of the sliding rod 71 is fixedly connected to a correction block 72, and the cross-sectional shape of the correction block 72 is a trapezoid; a matching cylinder 73 is provided below the correction block 72; a square groove 74 is provided on the top of the matching cylinder 73, and the square groove 74 corresponds to the correction block 72; the first limit plate 24 and the second limit plate 25 are both provided with an extrusion assembly, which is used to squeeze gas to drive the sliding rod 71 to slide; when the gear is conveyed, detected and screened, the gear is easily misaligned The gear is placed so that it is difficult to mesh with the multiple test teeth 42. First, insert the matching cylinder 73 into the central groove of the gear, and use the electric cylinder 33 to cover the gear intercepted by the extrusion component and transport it with the screening conveyor 1. The gear squeezes the extrusion component to send the gas to the inside of the fixed plate 7, and pushes the sliding rod 71 to drive the correction block 72 to extend downward. The No. 3 elastic part contracts and is stressed. The correction block 72 is inserted into the square groove 74 to correspond and correct the gear intercepted by the spacer plate 6 at the rear, which plays a role in auxiliary detection of gear correction. At the same time, the matching cylinder 73 can be installed in the central groove of the gear for protection and shielding to reduce impurities from falling into the central groove of the gear.

[0035] like Figures 1 to 5 As shown, the extrusion assembly includes an extrusion block 8, a fourth elastic member 81 and an air guide tube 82; the two extrusion blocks 8 are slidably connected to the inner walls of the first limit plate 24 and the second limit plate 25, and the extrusion block 8 is close to the middle position of the partition plate 6; the fourth elastic member 81 is fixed to the outside of the extrusion block 8; the two air guide tubes 82 are respectively fixed to the ends of the first limit plate 24 and the second limit plate 25, and the extrusion block 8 can squeeze the gas through the air guide tube 82 to the inside of the fixed plate 7 to push the sliding rod 71 to slide; when the sliding rod 71 is pushed The output end of the electric cylinder 33 is used to press the gear at the extrusion block 8. The gear continues to transport and extrude the two extrusion blocks 8 as the screening conveyor 1 continues to convey. The two extrusion blocks 8 are squeezed and slide into the interior of the No. 1 limit plate 24 and the No. 2 limit plate 25 respectively. The No. 4 elastic member 81 is squeezed and contracted, and the gas squeezed inside the No. 1 limit plate 24 and the No. 2 limit plate 25 is sent to the interior of the fixed plate 7 through the air guide pipe 82. The gas pushes the sliding rod 71 down, and the correction block 72 drives the gear equipped with the matching cylinder 73 to correct, which plays a role in correcting the gear transmission.

[0036] like Figure 1 , Figure 2 and Figure 4As shown, a cleaning frame 9 is fixed to the outside of the sliding rod 71; a plurality of scrapers are arranged at the bottom end of the cleaning frame 9; when the gear is calibrated, impurities are easily attached to the outer wall of the gear due to long-term placement, and the impurities affect the meshing test effect of the gear. The cleaning frame 9 is fixed to the outside of the sliding rod 71, and the plurality of scrapers at the bottom end of the cleaning frame 9 are arranged corresponding to the teeth of the gear. After the correction block 72 slides down to correct the gear, the plurality of scrapers at the bottom end of the cleaning frame 9 scrapes the outer wall of the gear to reduce the adhesion of impurities on the gear, thereby improving the meshing test effect of the gear.

[0037] like Figures 1 to 3 As shown, a rubber block 91 is fixedly connected to the outside of the No. 1 guide plate 12; one end of the rubber block 91 away from the No. 1 guide plate 12 is fixedly connected to the No. 1 limit plate 24; when the distance between the No. 1 limit plate 24 and the No. 2 limit plate 25 is adjusted, the rubber block 91 is connected between the No. 1 limit plate 24 and the No. 1 guide plate 12, and the rubber block 91 can synchronously drive the No. 1 guide plate 12 to adjust the angle, thereby realizing the effect of synchronously adjusting the distance between the two No. 1 guide plates 12. The rubber block 91 connected to the No. 2 limit plate 25 also works on the same principle. At the same time, by utilizing the connection of the rubber block 91, the rubber block 91 can block the accumulated gears and reduce the effect of the gears being stuck in the gap between the No. 1 guide plate 12 and the No. 1 limit plate 24.

[0038] Working process: When detecting and screening the gears of hardware accessories, first adjust the guide angle of the No. 1 guide plate 12, and the two sets of rotating shafts 11 are symmetrically arranged with the No. 1 guide plate 12. The spacing between the two No. 1 guide plates 12 reserves the diameter of a gear. Multiple gears are placed on the screening conveyor 1 for transportation. If the gears are placed on the screening conveyor 1 and conveyed offset, affecting the detection of the detection mechanism, the two No. 1 guide plates 12 correspond to the conveying track of the guide gears, and the limit assembly assists the conveying track of the limit gears, so that the gears can be guided and conveyed to the detection mechanism one by one for multiple tests at the same time, and finally the defective products are screened out, thereby improving the detection and screening efficiency of the gears. At the same time, when the screening When the gears are piled up on the sub-conveyor 1, the extrusion force of the stacked gears is greater than the torsion of the torsion spring, and the No. 1 guide plate 12 can be squeezed to match the rotation angle of the rotating shaft 11, thereby expanding the distance between the two No. 1 guide plates 12, and the torsion spring contracts and is stressed. When the stacked gears reach the limit assembly, they are guided for the second time, so that the gears return to the normal conveying trajectory, playing the role of adaptive conveying gears; when the gear conveying is detected, the sliding frame 21 is first slid on the fixed block 2, and the distance between the No. 1 limit plate 24 and the No. 2 limit plate 25 is adjusted to be consistent with the distance between the two No. 1 guide plates 12, and the No. 1 elastic member is used to drive the insertion rod 23 to penetrate the fixed block 2 and limit the limit hole 22, and the gear When the gear is transported to the No. 1 limit plate 24 and the No. 2 limit plate 25, the No. 1 limit plate 24 and the No. 2 limit plate 25 can limit the output track of the gear, so that the gear is transported to the detection mechanism for multiple detection and screening. At the same time, the front ends of the No. 1 limit plate 24 and the No. 2 limit plate 25 can guide the gear for transportation; when the gear is transported and tested, the fixed frame 3 supports the track frame 31 to be fixed above the No. 1 limit plate 24 and the No. 2 limit plate 25. After the gear is transported to the lower position of the track frame 31, the output end of a single electric cylinder 33 extends and covers the top of a single gear, and the electric slider drives the gear at the bottom of the electric cylinder 33 to follow the screening conveyor 1 for synchronous transportation, and the matching components are used for the meshing inspection of the hardware accessories. The monitor 32 synchronously detects the meshing degree and the incompleteness of the teeth of the conveying gear. After detecting the defective products, the personnel can be notified to remove them, which plays the role of synchronous multiple detection and screening of the gears; when the meshing detection of the gears is carried out, the connecting plate 4 is installed on the inner wall of the No. 1 limit plate 24, and a single gear is conveyed to the connecting plate 4. The correction tooth 41 first cooperates with the gear correction angle to facilitate the subsequent gears to be more easily matched with the multiple test teeth 42 for meshing detection. When the gears reach the multiple test teeth 42, the gears mesh with the multiple test teeth 42. The monitor 32 monitors the meshing degree and the incompleteness of the gears in real time, realizes the role of gear meshing detection, and removes the defective products when they are detected;When multiple test teeth 42 are testing the meshing of gears, if the meshing degree between multiple test teeth 42 and gears is unqualified, the output end of the servo motor 5 drives the connecting plate 4 to rotate an angle, and the connecting plate 4 assists in guiding the gears. As the screening conveyor 1 continues to transport the gears, the gears are transported through the guide grooves, and are assisted by the second guide plate 51 to another channel for unloading. The servo motor 5 drives the connecting plate 4 to rotate and reset again, so as to remove unqualified gears.

[0039] When the gears are conveyed for inspection and screening, multiple gears are placed closely on the screening conveyor 1 for transportation, which may affect the inspection effect. Two spacer plates 6 are symmetrically installed inside the No. 1 limit plate 24 and the No. 2 limit plate 25. The spacer plates 6 can block multiple gears. When the output end of the electric cylinder 33 is pressed on the frontmost gear, the frontmost gear slides and squeezes the spacer plate 6 to retract into the No. 1 limit plate 24. The No. 2 elastic member 61 contracts and is stressed. The pressed gear is sent for meshing inspection, and then the gear close to the spacer plate 6 will be transported to the interception position of the previous gear, waiting for the next The electric cylinder 33 plays the role of intermittently conveying and testing the gears one by one; when the gears are conveyed and screened, since the gears are easily misplaced, it is difficult for the gears to mesh with the multiple test teeth 42. First, the matching cylinder 73 is inserted into the central groove of the gear, and the electric cylinder 33 is used to press the gears intercepted by the extrusion assembly and convey them with the screening conveyor 1. The gears squeeze the extrusion assembly so that the gas is sent to the inside of the fixed plate 7, and the sliding rod 71 is pushed to drive the correction block 72 to extend downward. The third elastic member contracts and is stressed, and the correction block 72 is inserted into the square groove 74 to correspond, and the correction is intercepted by the spacer plate 6 at the rear. The gear plays the role of auxiliary detection of gear correction. At the same time, the matching cylinder 73 can be installed in the central groove of the gear for protection and shielding to reduce impurities from falling into the central groove of the gear. When the sliding rod 71 is pushed, the output end of the electric cylinder 33 is pressed on the gear at the extrusion block 8. The gear continues to be conveyed and squeezed by the screening conveyor 1. The two extrusion blocks 8 are squeezed and slide into the interior of the No. 1 limit plate 24 and the No. 2 limit plate 25 respectively. The No. 4 elastic member 81 is squeezed and contracted to bear the force, and the gas squeezed inside the No. 1 limit plate 24 and the No. 2 limit plate 25 is sent to the air guide pipe 82. Inside the fixed plate 7, the gas pushes the sliding rod 71 downward, and the correction block 72 drives the gear equipped with the matching cylinder 73 to correct, which plays a role in correcting the gear transmission; when correcting the gear, since the outer wall of the gear is easily attached with impurities after being placed for a long time, the impurities affect the meshing test effect of the gear, and the cleaning frame 9 is fixed to the outside of the sliding rod 71. The multiple scrapers at the bottom of the cleaning frame 9 are set corresponding to the teeth of the gear. After the correction block 72 first slides down to correct the gear, the multiple scrapers at the bottom of the cleaning frame 9 scrape the outer wall of the gear to reduce the adhesion of impurities on the gear, thereby improving the meshing test effect of the gear;

[0040] When adjusting the distance between the No. 1 limit plate 24 and the No. 2 limit plate 25, a rubber block 91 is connected between the No. 1 limit plate 24 and the No. 1 guide plate 12. The rubber block 91 can synchronously drive the No. 1 guide plate 12 to adjust the angle, thereby achieving the effect of synchronously adjusting the distance between the two No. 1 guide plates 12. The rubber block 91 connected to the No. 2 limit plate 25 also works on the same principle. At the same time, by utilizing the connection of the rubber block 91, the rubber block 91 can block the accumulated gears and reduce the effect of the gears being stuck in the gap between the No. 1 guide plate 12 and the No. 1 limit plate 24.
