Description

Electrical fitting resistance testing equipment Technical Field

[0001] This invention relates to the field of power fitting testing equipment technology, specifically to power fitting resistance testing equipment. Background Technology

[0002] During the production of power fittings, it is necessary to conduct regular spot checks on the same batch of power fittings. Power fitting resistance testing equipment is a core quality inspection equipment in the production process of power system supporting components. It is mainly used to test the conductivity and resistance value of power fittings (such as clamps, mounting plates, connectors, etc.), to investigate poor conductivity caused by material defects and processing errors, and at the same time provide preliminary testing support for the re-inspection of the corrosion resistance of fittings.

[0003] Traditional electrical fitting resistance testing equipment typically requires manual placement of fittings on a fixed support platform, manual adjustment of conductive probes to establish a testing circuit, and manual sorting of qualified and unqualified products after testing. Some equipment requires additional temperature measuring instruments for monitoring, making the process cumbersome. To address this, automated testing equipment has emerged. This type of equipment usually features basic support and conductive structures, replacing the manual adjustment of conductive probes to establish a testing circuit, facilitating fitting loading and improving testing efficiency. However, in practical use, the following drawbacks remain: the conductive circuit continuity, fitting support, and sorting and conveying in the aforementioned equipment are mostly independently controlled. After testing, manual unloading and conveying of fittings using the sorting and conveying structure based on the test results are still required. Furthermore, existing equipment lacks a corresponding conveying structure for re-inspecting the corrosion resistance of qualified fittings after testing, requiring manual transfer to a salt spray chamber, resulting in low efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a power fitting resistance testing device, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a power fitting resistance testing device, comprising: a testing component including a base and a resistance tester fixedly mounted thereon, with a positive wire and a negative wire fixedly connected to the resistance tester; and a positioning testing mechanism including a mounting base, mounting plates, supporting components, a testing positioning component, and a temperature testing component.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] To address the technical problems in the background art, the following power fitting resistance testing device is provided: As shown in Figures 1-13, the power fitting resistance testing device provided by the present invention includes: a testing component 1, which includes a base 11 and a resistance tester 12 fixedly mounted thereon, with a positive electrode wire 121 and a negative electrode wire 122 fixedly connected to the resistance tester 12; and a positioning testing mechanism 2, which includes a mounting base 21, a mounting plate 22, a support component 23, a testing positioning component 24, and a temperature testing component 25. The mounting base 21 is fixedly mounted on the base 11 and located on one side of the resistance tester 12. Vertical mounting plates 22 are symmetrically fixedly mounted on the top of the mounting base 21. Supporting components 23 are slidably mounted on mounting plate 22. Power fitting bodies 3 are placed on top of the two supporting components 23 and on opposite sides of the two mounting plates 22. A resistance detector 12 is communicatively connected to a PLC control system. The PLC control system has preset single-time detection time and temperature threshold values ​​for the power fitting body 3. Both mounting plates 22 are equipped with detection positioning components 24 that can contact the top of the power fitting body 3. One set of detection positioning components 24 is equipped with a temperature detection component 25 that can contact the power fitting body 3. A conductive mechanism 4, comprising a first conductive plate 41, a second conductive plate 42, and a conductive opening / closing component 43, is mounted on a base 11 and located on... A horizontally oriented conductive plate 41 and conductive plate 42 are fixedly mounted on one side of the mounting base 21. A positive electrode wire 121 is connected to one set of detection and positioning components 24, and a negative electrode wire 122 is connected to conductive plate 41. The end of conductive plate 42 away from conductive plate 41 is connected to another set of detection and positioning components 24. A conductive opening and closing component 43 is mounted on the base 11 to close or open the connection between conductive plate 41 and conductive plate 42. A transmission mechanism 5 is mounted on the base 11, with one end connected to the conductive opening and closing component 43 and connected to two sets of supporting components 23. A sorting and guiding mechanism 6 includes a bracket 61 and a guiding assembly 62. A salt spray chamber 13 is placed on the base 11 and on one side of the mounting base 21. Specifically, the top of the salt spray chamber 13 is open, a filter plate is fixedly installed inside the salt spray chamber 13, a spray pipe is fixedly installed on the inner side wall of the salt spray chamber 13 above the filter plate, and a connecting pipe is connected through the salt spray chamber 13 to its inner bottom wall. A conveyor belt 26 is installed on the mounting base 21 on the side of the two mounting plates 22 away from the salt spray chamber 13. A bracket 61 is fixedly installed on the top of the mounting base 21 and below the two sets of supporting components 23. A guide assembly 62 is rotatably installed on the bracket 61, and a motor is fixedly installed at the rotatable connection. The motor is connected to the PLC control system.Resistance testing of electrical fittings: When the conductive opening and closing component 43 moves, it contacts both conductive plate 41 and conductive plate 42. The main body 3 of the electrical fitting is placed on two sets of supporting components 23. Two sets of detection and positioning components 24 press against the main body 3 of the electrical fitting. The temperature detection component 25 contacts the main body 3 of the electrical fitting. When the resistance test is qualified, the conductive opening and closing component 43 moves and does not contact conductive plate 41 and conductive plate 42. The transmission mechanism 5 drives the two sets of supporting components 23 to slide away. The motor drives the conveying component 62 to rotate and adjust the conveying direction. The main body 3 of the electrical fitting falls onto the conveying component 62 and is conveyed into the salt spray chamber 13 through the conveying component 62. When the resistance test is unqualified, the motor drives the conveying component 62 to rotate and adjust the conveying direction. The main body 3 of the electrical fitting falls onto the conveying component 62 and is conveyed onto the conveyor belt 26 through the conveying component 62.

[0020] In use, the positive wire 121 and negative wire 122 of the resistance detector 12 are connected to the conductive mechanism 4 and two sets of detection and positioning components 24 to form a detection circuit. The positioning and detection mechanism 2, through the support component 23 and the detection and positioning component 24, realizes stable support and voltage conduction of the main body 3 of the power fitting. The temperature detection component 25 monitors the temperature of the main body 3 of the power fitting in real time during detection to avoid the temperature affecting the detection accuracy. The conductive opening and closing component 43 of the conductive mechanism 4 can control the opening and closing of the detection circuit and is linked with the transmission mechanism 5. When the circuit is disconnected, it synchronously drives the two sets of support components 23 to separate, so that the main body 3 of the power fitting will fall automatically. The classification and conveying mechanism 6 adjusts the conveying direction of the conveying component 62 through the motor, and guides qualified fittings to the salt spray box 13 for corrosion re-inspection, and guides unqualified fittings to the conveyor belt 26 for unloading, without the need for manual sorting. The overall structure realizes the linkage control of detection, positioning, opening and closing, support, and classification and conveying, improving detection efficiency and automation.

[0021] In this embodiment, the supporting component 23 includes a sliding plate 231 and a supporting plate 232. The sliding plate 231 is horizontally movably inserted through the mounting plate 22. The supporting plate 232 is fixedly installed at one end of the two mounting plates 22 that are close to each other. In the above scheme, the sliding plate 231 horizontally movably inserts through the mounting plate 22, so that it can slide horizontally along the mounting plate 22, causing the supporting plate 232 to move closer or further away, adapting to the support requirements of power fitting bodies 3 of different width specifications. The supporting plate 232 provides stable bottom support for the power fitting body 3, ensuring the horizontal state of the fitting during testing and avoiding poor conductive contact due to tilting. Furthermore, the sliding plate 231 is connected to the transmission mechanism 5, and can achieve automatic synchronous sliding under the drive of the transmission mechanism 5. After the test is completed, no manual operation is required, and the supporting plate 232 can be quickly separated, allowing the fitting to fall smoothly onto the guide component 62.

[0022] In this embodiment, the detection and positioning component 24 includes a conductive rod 241, a conductive frame 242, a conductive post 243, a voltage-conducting plate 244, and an adjusting screw 245. A horizontally oriented conductive rod 241 is fixedly mounted on the mounting plate 22 above the sliding plate 231. The positive electrode wire 121 is fixedly connected to the conductive rod 241 of the detection and positioning component 24. A conductive frame 242 is fixedly mounted on the top of the conductive rod 241 between the two mounting plates 22. A conductive post 243 is vertically movably inserted through the conductive frame 242 above the support plate 232. A voltage-conducting plate 244 is fixedly mounted at the bottom of the conductive post 243. An adjusting screw 245 is threaded vertically through the conductive frame 242. The bottom of the adjusting screw 245 is rotatably connected to the voltage-conducting plate 244. Temperature detection... Component 25 is mounted on the conductive frame 242. In the above scheme, the detection and positioning component 24 adopts a conductive rod 241, conductive frame 242, conductive column 243, conductive voltage plate 244 and adjusting screw 245 to form a conductive adjustable holding structure. All components are made of conductive materials, forming an integrated conductive path. While positioning and holding, the conductive connection of the detection circuit is completed, and there is no need to arrange a separate conductive structure. The adjusting screw 245 is threaded through the conductive frame 242. Rotation can drive the conductive voltage plate 244 to rise and fall vertically along the conductive column 243, adjusting the height of the conductive voltage plate 244 to ensure tight conductive contact between the conductive voltage plate 244 and the main body 3 of the power fitting. At the same time, the height of the conductive voltage plate 244 can be flexibly adjusted according to the thickness of the main body 3 of the power fitting to adapt to the detection and positioning requirements of fittings with different thicknesses and specifications, improving the versatility of the equipment.

[0023] In this embodiment, the temperature detection component 25 includes a horizontal plate 251, a guide rod 252, a connecting plate 253, a temperature sensor 254, and an adjusting screw 255. The horizontal plate 251 is slidably mounted horizontally on the side of the conductive frame 242 away from the mounting plate 22. The guide rod 252 is vertically threaded through the horizontal plate 251. The connecting plate 253 is fixedly mounted at the bottom of the guide rod 252, and the temperature sensor 254 is fixedly mounted at the bottom of the connecting plate 253. The adjusting screw 255 is threaded vertically through the horizontal plate 251, and the adjusting screw 255 is rotatably connected to the connecting plate 253. In this design, the horizontal plate 251 can slide horizontally along the conductive frame 242 to adjust the horizontal position of the temperature sensor 254. This allows for adjustment of the monitoring point according to the size of the power fittings and the testing requirements, thus avoiding monitoring deviations. The adjusting screw 255 drives the connecting plate 253 to rise and fall vertically along the guide rod 252, adjusting the height of the temperature sensor 254 in contact with the power fittings. This ensures a tight fit between the temperature sensor 254 and the fittings, improving the accuracy of the temperature detection data. The bidirectional adjustment function allows the temperature sensor 254 to adapt to the temperature monitoring needs of power fittings of different specifications and shapes, ensuring real-time and accurate feedback of temperature data during the testing process.

[0024] In this embodiment, the conductive opening and closing component 43 includes a hinge shaft 431, a movable conductive plate 432, and a drive rod 433. The horizontally oriented hinge shaft 431 is rotatably mounted on the base 11. One end of the hinge shaft 431 is fixedly connected to the movable conductive plate 432. The drive rod 433, which is hinged to the movable conductive plate 432, is connected to the base 11. The drive rod 433 is communicatively connected to the PLC control system. When the movable conductive plate 432 rotates around the hinge shaft 431, both ends of the movable conductive plate 432 can contact the first conductive plate 41 and the second conductive plate 42 respectively. In the above scheme, the drive rod 433 drives the movable conductive plate 432 to rotate around the hinge shaft 431, thereby realizing the contact or separation of the movable conductive plate 432 with the first conductive plate 41 and the second conductive plate 42, completing the rapid on / off of the detection circuit, which is easy to operate. The hinge shaft 431 is directly connected to the transmission mechanism 5, realizing the linkage control of the opening and closing of the conductive circuit and the sliding of the supporting component 23, improving the automation level of the equipment.

[0025] In this embodiment, the transmission mechanism 5 includes a sliding rod 51, a connecting rod 52, a rack 53, and a gear 54. Two sliding rods 51 and two connecting rods 52 are slidably mounted horizontally on the base 11. The two connecting rods 52 are respectively connected to the ends of the two sliding rods 51 that are far apart from each other, and the other ends of the two connecting rods 52 are respectively fixedly connected to the ends of the two sliding plates 231 that are far apart from each other. A rack 53 is fixedly mounted on each of the two sliding rods 51. The two racks 53 are symmetrically staggered. A gear with two meshing racks 53 is coaxially fixed on the hinge shaft 431. 54. In the above scheme, when the hinge shaft 431 rotates, it drives the gear 54 to rotate synchronously. By meshing with two symmetrically staggered racks 53, it drives the two sliding rods 51 to slide synchronously in opposite directions. Then, through the connecting rod 52, it drives the two supporting components 23 to separate or reset synchronously in opposite directions. The action synchronization is high. Moreover, the gear 54 and rack 53 have high transmission accuracy, and the sliding process is smooth and without deviation, ensuring the sliding accuracy of the supporting component 23. This structure transforms the rotation action of the conductive opening and closing component 43 into the sliding action of the supporting component 23, realizing the linkage between the detection circuit on / off and the hardware support.

[0026] In this embodiment, the guiding assembly 62 includes a fixed frame 621, a guiding frame 622, and a guiding plate 623. The fixed frame 621 is rotatably connected to the top of the support 61. The inclined guiding frame 622 is detachably installed on the inner side of the fixed frame 621. The guiding plate 623 is installed on the top of the guiding frame 622 and engages with it. In the above scheme, the fixed frame 621 is rotatably connected to the support 61, and the guiding direction can be adjusted under the drive of the motor to achieve the classification and guiding of qualified and unqualified hardware. The guiding frame 622 is detachably connected to the fixed frame 621, and the guiding plate 623 is engaged with the guiding frame 622. When the guiding plate 623 is worn or damaged, it can be disassembled and replaced separately without replacing the entire assembly, reducing maintenance costs. The detachable structure also allows the guiding frame 622 to be removed separately and used as a gripper, which facilitates the handling of hardware in the salt spray chamber and enhances the multi-functionality of the equipment.

[0027] In this embodiment, the guide frame 622 includes a fixed rod 6221, a clamping rod 6222, and a spring 6223. A clamping rod 6222 is symmetrically slidably mounted on one side of the fixed rod 6221. A horizontally oriented spring 6223 is fixedly mounted on the opposite sides of the two clamping rods 6222. Each clamping rod 6222 has a locking hole 6224 on its opposite side. A locking block 6211 is integrally formed on the inner walls of both sides of the fixed frame 621. When the two locking blocks 6211 are inserted into the two locking holes 6224, they engage with the two clamping rods 6222 respectively. The guide plate 623 has an L-shaped longitudinal section. Limiting strips 6231 are symmetrically fixed to the bottom of the guide plate 623. When the guide plate 623 is hung on the fixed rod 6221, the guide plate 623 is in contact with both clamping rods 6222, and the two limiting strips 6231 are respectively engaged with… The two clamping rods 6222 are close to each other on one side, forming abutment. In the above scheme, pressing the two clamping rods 6222 compresses the spring 6223, causing the locking hole 6224 to separate from the locking block 6211, realizing the quick disassembly of the guide frame 6222. After releasing the clamping rods 6222, the spring 6223 pushes the clamping rods 6222 back to their original position, and the locking block 6211 is inserted into the locking hole 6224 to complete the quick installation. The operation is simple. The guide plate 623 has an L-shaped structure and is engaged with the clamping rods 6222 through the limiting strip 6231, preventing the guide plate 623 from falling off during the hardware conveying process. The elastic force of the spring 6223 makes the clamping rods 6222 and the locking block 6211 tightly engaged, realizing the self-positioning and locking of the guide frame 6222. There is no loosening after installation, ensuring the stability of the conveying process. In addition, the two limiting strips 6231 of the guide plate 623 further limit the two clamping rods 6222.

[0028] In this embodiment, the two mounting plates 22 are horizontally slidably mounted on the top of the mounting base 21. An adjusting component 7 is installed on the mounting base 21, which acts on the two mounting plates 22 to allow them to slide in opposite directions or stop sliding on the mounting base 21. A conductive slide rod 2411 is integrally formed at the end of the conductive rod 241. The second conductive plate 42 is movably sleeved outside the conductive slide rod 2411 and its cross-section is in contact with the conductive slide rod 2411. The connecting rod 52 is movably slidable outside the sliding rod 51, and a positioning pin 521 that abuts against the sliding rod 51 is threaded through the connecting rod 52. In this configuration, the two mounting plates 22 are horizontally slidably mounted on the mounting base 21. The spacing can be adjusted according to the width of the power fittings to adapt to the testing needs of fittings of different widths and specifications, thus improving the versatility of the equipment. The conductive slide rod 2411 at the end of the conductive rod 241 is movably connected to the conductive plate 22. When the mounting plate 22 slides, the conductive slide rod 2411 can slide along the conductive plate 22 to ensure the continuity of the conductive path. The connecting rod 52 is movably sleeved outside the sliding rod 51 to adapt to the spacing adjustment of the mounting plate 22. The positioning pin 521 can rigidly lock the connecting rod 52 and the sliding rod 51 to ensure transmission accuracy. The locking and unlocking operation of the positioning pin 521 is simple and can quickly complete the positioning and adjustment of the connecting rod 52 and the sliding rod 51 to adapt to the transmission needs of fittings of different specifications.

[0029] In this embodiment, the top of the mounting base 21 is symmetrically provided with sliding grooves, and the bottoms of the two mounting plates 22 extend into the two sliding grooves and are slidably connected to the mounting base 21. The adjusting component 7 includes a bidirectional threaded rod 71 that is horizontally rotatably mounted on the mounting base 21. The bidirectional threaded rod 71 is threadedly connected to both mounting plates 22. The inner sidewall of the sliding groove is provided with a receiving groove, and a sealing plate 221 for sealing the opening end of the sliding groove is slidably connected in the receiving groove. The two sealing plates 221 are fixedly connected to the opposite sides of the two mounting plates 22. In the above scheme, the bidirectional threaded rod 71 is threadedly connected to the two mounting plates 22. Rotating the bidirectional threaded rod 71 can drive the two mounting plates 22 to slide synchronously in opposite directions, which is simple to operate. By setting the sealing plate 221, the sealing effect of the two sliding grooves located on the side close to each other of the two mounting plates 22 is achieved, which effectively prevents the main body of the power fitting 3 from accidentally falling into the sliding groove.

[0030] The working principle and usage process of this invention are as follows: When performing resistance detection on the main body 3 of the power fitting: the drive rod 433 is controlled to rotate the movable conductive plate 432 around the hinge shaft 431, so that both ends of the movable conductive plate 432 contact the first conductive plate 41 and the second conductive plate 42 respectively. The two positioning pins 521 are rotated so that the positioning pins 521 do not abut against the sliding rod 51, thus canceling the positioning between the sliding rod 51 and the connecting rod 52. According to the size of the main body 3 of the power fitting, the bidirectional threaded rod 71 is rotated so that the two mounting plates 22 slide in opposite directions on the mounting base 21 and move closer to each other. The two sealing plates 221 slide synchronously to seal the opening ends of the two slide grooves in real time. The two connecting rods 52 are pushed so that the two connecting rods 52 are respectively in contact with the two mounting plates 22. The distance between the two support plates 232 is made smaller than the width of the power fitting body 3. The two positioning pins 521 are rotated in the opposite direction, so that the two positioning pins 521 abut against the two sliding rods 51 respectively, and the two connecting rods 52 are positioned between the two sliding rods 51 respectively. During this process, the positive electrode wire 121 is deformed, and the connecting rods 52 slide outside the conductive sliding rods 2411. The power fitting body 3 is placed on the two support plates 232, and the two adjusting screws 245 are rotated respectively, so that the adjusting screws 245 spiral downward on the conductive frame 242, which respectively drive the two conductive plates 244 to move downward along the conductive column 243 and fit against the two ends of the top of the power fitting body 3. At this time, the positive electrode wire 121 passes through the conductivity of one of the sets of detection and positioning components 24. Rod 241, conductive frame 242, conductive column 243, and voltage-conducting plate 244 are connected to one end of the power fitting body 3. The negative electrode wire 122 is connected to the other end of the power fitting body 3 through conductive plate 1 41, movable conductive plate 432, conductive plate 2 42, conductive slide rod 2411, and another set of detection and positioning components 24, including conductive rod 241, conductive frame 242, conductive column 243, and voltage-conducting plate 244, thus achieving the purpose of connecting both the positive electrode wire 121 and the negative electrode wire 122 of the resistance detector 12 to the power fitting body 3. Rotating the adjusting screw 255 causes it to spiral downward on the horizontal plate 251, driving the connecting plate 253 to move downward along the guide rod 252, causing the temperature sensor 254 to slide downward, and then pushing the horizontal plate 251. The horizontal sliding fit allows the temperature sensor 254 to be in contact with the power fitting body 3. At this time, the resistance detector 12 can be controlled to work and the resistance of the power fitting body 3 can be set according to the model of the power fitting body 3 to detect the power fitting body 3. During this period, the temperature sensor 254 monitors the temperature of the power fitting body 3 in real time and feeds it back to the PLC control system. When the temperature monitored by the temperature sensor 254 of the power fitting body 3 is lower than the detection state temperature threshold of the power fitting body 3 within the detection time, the power fitting body 3 passes the initial inspection. The PLC control system controls the motor to work, so that the fixed frame 621 rotates on the bracket 61, so that the guide frame 622 and the guide plate 623 rotate around the bracket 61, so that the guide plate 623 tilts downward along the direction of the salt spray box 13.The control drive rod 433 causes the movable conductive plate 432 to rotate around the hinge shaft 431, so that both ends of the movable conductive plate 432 do not contact the first conductive plate 41 and the second conductive plate 42. The rotation of the hinge shaft 431 drives the gear 54 to rotate, and through the two racks 53, the two sliding rods 51 slide in opposite directions and move away from each other. Thus, through the two connecting rods 52, the two sliding plates 231 slide away from each other on the two mounting plates 22, causing the two supporting plates 232 to displace outward from the power fitting body 3 and no longer support the power fitting body 3. At this time, the power fitting body 3 falls downward to the guide. The material slides down the guide plate 623 onto the filter plate inside the salt spray chamber 13. A lid is placed on the salt spray chamber 13 to seal its top opening, allowing the salt spray chamber 13 to corrode the internal electrical fitting body 3. This corrosion is then used for subsequent resistance testing of the corroded electrical fitting body 3. During testing, if the temperature sensor 254 detects a temperature higher than the detection threshold of the electrical fitting body 3, the initial inspection of the electrical fitting body 3 fails. The PLC control system then controls the motor to operate, causing the fixing frame 621 to move onto the support 61. The upward rotation causes the guide frame 622 and guide plate 623 to rotate around the support 61, causing the guide plate 623 to tilt downwards along the conveyor belt 26. The control drive rod 433 causes the movable conductive plate 432 to rotate around the hinge shaft 431, so that both ends of the movable conductive plate 432 do not contact the first conductive plate 41 and the second conductive plate 42, causing the two support plates 232 to shift outwards from the power fitting body 3 and no longer support the power fitting body 3. At this time, the power fitting body 3 falls downwards onto the guide plate 623, and then slides down along the guide plate 623 onto the conveyor belt 26, thus being transported by the conveyor. 26 pairs of unqualified power fitting bodies 3 are transported; after the salt spray box 13 performs salt spray corrosion on the power fitting bodies 3 inside, when the power fitting bodies 3 that passed the initial inspection are re-inspected after salt spray corrosion: the operator controls the control drive rod 433 to make the movable conductive plate 432 rotate around the hinge shaft 431, so that the two ends of the movable conductive plate 432 contact the first conductive plate 41 and the second conductive plate 42 respectively, so that the two support plates 232 are reset, and then the two adjusting screws 1 245 and 2 255 are rotated respectively to reset the voltage plate 244 and the temperature sensor 254.The operator manually removes the guide plate 623, releasing the restriction on the two clamping rods 6222. Then, holding the outer sides of the two clamping rods 6222, the operator presses them down and slides them in opposite directions onto the fixed rod 6221, bringing them closer together. This causes the two clamping rods 6222 to move to opposite sides of the two locking blocks 6211, causing the spring 6223 to contract. The guide frame 622 can then be disassembled. At this point, the guide frame 622 is in a gripper state, allowing the operator to use it to remove the salt-spray-corroded electrical fitting body 3 from the salt spray chamber 13 and place it on the two support plates 232, thus completing the salt-spray-corroded electrical fitting body treatment. 3. After loading the material, by rotating the two adjusting screws 245 and 255, the two conductive plates 244 are respectively attached to the two ends of the top of the power fitting body 3, and the temperature sensor 254 is attached to the power fitting body 3. At this time, the resistance detector 12 can be controlled to work to perform resistance testing on the power fitting body 3 after salt spray corrosion treatment. The operator holds the two clamping rods 6222 on the outside and presses the two clamping rods 6222 on the fixed rod 6221 to slide them in opposite directions and bring them closer together, placing the two clamping rods 6222 on the inside of the fixed frame 621, and making the locking holes 6224 on the two clamping rods 6222 close together. With the two locking blocks 6211 facing each other, the pressing force on the two clamping rods 6222 is released. The spring 6223 unfolds and pushes the two clamping rods 6222 back to their original positions. The two locking blocks 6211 are then inserted into the two locking holes 6224, limiting the position of the guide frame 622. The guide plate 623 is then hung on the fixed rod 6221, completing the installation of the guide frame 622 and the guide plate 623 for guide use. During this process, the two limiting strips 6231 are inserted into the inside of the two clamping rods 6222. When the guide plate 623 is in contact with the two clamping rods 6222, the two limiting strips 6231 move closer to each other. When the side forms contact, it further positions the guide frame 622; if the inspection fails, similarly, the PLC control system controls the motor and drive rod 433 to work together, causing the power fitting body 3 to fall downwards onto the guide plate 623, and then slide down along the guide plate 623 onto the conveyor belt 26, where the unqualified power fitting body 3 can be transported; if the inspection passes, similarly, the PLC control system controls the motor and drive rod 433 to work together, causing the power fitting body 3 to fall downwards into the salt spray chamber 13, making it easier for workers to distinguish between qualified and non-standard power fitting bodies 3.
