DETAILED DESCRIPTION

[0036] Example: Figures 1 to 10 As shown, a single-channel universal automobile lock buckle eddy current hardness nondestructive testing device comprises a testing platform 1, on which a first conveying mechanism 2, a demagnetizing mechanism 3, a second conveying mechanism 4, an eddy current hardness testing probe 5 and a collecting channel 6 are fixedly installed in sequence, and two baffle plates 7 are fixedly installed on the top of the first conveying mechanism 2 and the second conveying mechanism 4, and a material dividing mechanism 8 is fixedly installed on the top of the two baffle plates 7;

[0037] A material discharge plate 61 is fixedly installed inside the collecting channel 6, a partition 62 is fixedly installed inside the collecting channel 6, and the partition 62 divides the collecting channel 6 into two discharge ports 63. A material guide plate 64 is rotatably connected inside the collecting channel 6, and two first cylinders 65 are rotatably connected inside the collecting channel 6. The output ends of the two first cylinders 65 are both rotatably connected to one side of the material guide plate 64. During implementation, a collecting box is placed below the two discharge ports 63. When the car lock buckle 10 after the hardness test falls from the second conveying mechanism 4 onto the collecting channel 6, if the test is qualified, the first cylinder 65 is extended to open the material guide plate 64 (see Figure 8), the qualified car lock buckle 10 enters the discharge port 63 near the first cylinder 65 under the action of inertia and falls into the collection box, and when the unqualified car lock buckle is detected, the output shaft of the first cylinder 65 is contracted to close the guide plate 64 (see Fig. 9 ), the car lock buckle 10 is blocked by the guide plate 64 during the falling process, enters the discharge port 63 below the collecting channel 6, and falls into the corresponding collecting box to achieve automatic classification.

[0038] The first conveying mechanism 2 and the second conveying mechanism 4 each include a support frame 9 and a driving motor 91. The interior of the support frame 9 is rotatably connected to two rotating shafts, and two synchronous pulleys are fixedly installed on the outer surface of each rotating shaft. Several synchronous pulleys are grouped in pairs, and the two synchronous pulleys in the same group are rotatably connected by a synchronous belt. The structure is simple, and technical personnel can implement it in conjunction with the drawings, and the details are not repeated here.

[0039] One side of the driving motor 91 is fixedly mounted on the top of the testing platform 1 , and a coupling (known technology) is fixedly mounted on the output end of the driving motor 91 , and one side of the coupling is fixedly mounted on one side of the corresponding rotating shaft.

[0040] The four baffle plates 7 are grouped in pairs, and a locking channel is left between the two baffle plates 7 in the same group. A number of automobile locks 10 are placed inside the locking channel. The baffle plates 7 located on the first conveying mechanism 2 and the second conveying mechanism 4 are the same except for the shape and length at the entrance. The entrance of the baffle plate 7 located on the first conveying mechanism 2 is used to place the automobile lock 10, and the entrance of the baffle plate 7 located on the second conveying mechanism 4 is in an inclined state, which can provide guidance for the automobile lock 10 so that it automatically merges into the corresponding locking channel.

[0041] The demagnetization mechanism 3 includes an inclined channel 31 and two adjustment plates 32 installed on the detection platform 1, and a demagnetizer 33 is fixedly installed between the two adjustment plates 32. When implemented, the adjustment plates 32 of different heights can be replaced to cope with automobile locks 10 of different heights.

[0042] Two mounting brackets 51 are fixedly installed on one side of the eddy current hardness detection probe 5, and the two mounting brackets 51 are fixedly installed on both sides of the second conveying mechanism 4 by bolts. The eddy current hardness detection probe 5 is an existing mature equipment, and the utility model does not improve it, and the specific implementation will not be repeated here.

[0043] The material dividing mechanism 8 includes a fixing part 81 and a second cylinder 82 installed on the material baffle plate 7. A photoelectric sensor 82 is fixedly installed inside the fixing part 81. The use of the photoelectric sensor 82 is very mature, and the specific implementation will not be repeated here. The photoelectric sensor 82 is used to detect whether there is material at the material dividing plate 83, so as to cooperate with the second cylinder 82 to divide the car lock 10. A material dividing plate 83 is fixedly installed at the output end of the second cylinder 82, and a through groove 84 is opened on one side of the material dividing plate 83. The photoelectric sensor 82 located on the second conveying mechanism 4 can cooperate with the second conveying mechanism 4 moving at a uniform speed to determine whether the hardness test of the car lock 10 currently falling into the collection channel 6 is qualified.

[0044] The inner part of the material dividing plate 83 is slidably connected with a guide rod 85, and a pressure plate 86 is fixedly installed on one side of the two guide rods 85. The outer part of the two guide rods 85 is sleeved with a spring. Since this part of the structure is relatively mature, the spring is not shown in the figure. The technicians can implement it according to the scheme. The two sides of the two springs are respectively overlapped on one side of the material dividing plate 83 and the pressure plate 86. Figure 3 As shown, when feeding is required, the output end of the second cylinder 82 pushes the dividing plate 83 so that the through slot 84 of the dividing plate 83 is aligned with the lock channel. At this time, the car lock 10 can pass through the through slot 84, and while the second cylinder 82 pushes the dividing plate 83, the pressure plate 83 presses the car lock 10 on the rear side under the action of the spring to prevent it from feeding through the through slot 84. After completing the feeding of one car lock 10, the second cylinder 82 pulls the dividing plate 83, and the pressure plate 83 releases the corresponding car lock 10 so that it can move forward and is blocked after contacting the dividing plate 83. When the second cylinder 82 is actuated again, the feeding is completed. The second cylinder 82 completes the feeding of one car lock 10 each time it is actuated, thereby achieving the feeding effect.

[0045] The cylinder, motor and photoelectric sensor that appear in the utility model are all controlled by an external main controller, and the main controller can be a conventional known device that controls a computer, etc. The components provided by the utility model are only used for the technical solution according to the structural characteristics of the product. The product will be adjusted and modified after purchase to make it more matching and consistent with the technical solution of the utility model. It is a technical solution for the best application of the technical solution. The model of the product can be replaced and modified according to the required technical parameters. It is well known to technical personnel in this field. Therefore, technical personnel in this field can clearly obtain the corresponding use effect through the technical solution provided by the utility model.

[0046] A single-channel universal automobile lock eddy current hardness non-destructive testing device, the working principle is as follows:

[0047] 1) When in use, a worker (since the placement position is fixed, it can also be placed by a manipulator) places the car lock buckle 10 to be tested on the synchronous belt of the first conveying mechanism 2 on one side of the testing table 1. The lock buckles are evenly arranged in the lock buckle channel under the action of the baffle plate 7, and the material is divided by the dividing mechanism 8, so that the car lock buckles 10 enter the inclined slide 31 of the demagnetization mechanism 3 from the first conveying mechanism 2 one by one, and slide to the demagnetizer 33 under the action of gravity for demagnetization;

[0048] 2) The demagnetized automobile lock buckle 10 slides down the inclined slide 31 onto the second conveying mechanism 4, enters the corresponding lock buckle channel under the guidance of the baffle plate 7, and performs secondary material distribution under the action of the distribution mechanism 8 located on the second conveying mechanism 4, so that the demagnetized automobile lock buckle 10 passes through the eddy current hardness detection probe 5 one by one for hardness detection, and the detection result is sent to the main controller, and the automobile lock buckle 10 that has completed the detection falls into the collection channel 6 from the tail end of the second conveying mechanism 4;

[0049] 3) Through the photoelectric sensor 87 on the second conveying mechanism 4, the main controller can timely understand whether the car lock 10 currently falling into the collection channel 6 is qualified, and then control the first cylinder 65 to act. If the detection is qualified, the first cylinder 65 is extended to open the guide plate 64 (see Figure 8 ), the qualified automobile lock buckle 10 enters the discharge port 63 near the first cylinder 65 under the action of inertia and falls into the qualified product collection box, while the unqualified ones are detected by the first cylinder 65 output shaft contraction, closing the guide plate 64 (see Fig. 9 ), the automobile lock buckle 10 is blocked by the guide plate 64 during the falling process, enters the discharge port 63 below the collecting channel 6, and falls into the unqualified product collection box to achieve automatic classification.
