Description

Technical Field

[0001] This utility model relates to the field of resistance testing machine technology, and more specifically, to a multi-angle contact resistance testing machine. Background Technology

[0002] In the field of thermostat manufacturing and quality inspection, contact resistance is one of the core indicators for judging the performance of thermostats. Accurate testing of it is a key link to ensure the reliability and safety of thermostats. Although some thermostat contact resistance testing devices on the market have certain testing functions, they have significant defects in thermostat angle adjustment. In the current testing process, after placing the temperature controller on the equipment, the operator needs to manually adjust the angle of the temperature controller to align the temperature controller contacts with the test terminals on the testing machine. However, this manual adjustment method has many problems. On the one hand, manual angle adjustment relies on the operator's experience and skill level, and the adjustment process is time-consuming, making it difficult to achieve quick and accurate alignment, resulting in a significant reduction in testing efficiency and failing to meet the high-efficiency requirements of large-scale production testing of temperature controllers. On the other hand, the accuracy of manual angle adjustment is difficult to guarantee. Even a small angular deviation may lead to poor contact and uneven force between the temperature controller contacts and the test terminals, causing unstable transmission of the test current and resulting in test data deviations that cannot accurately reflect the contact resistance performance of the temperature controller. Therefore, it needs to be improved. Utility Model Content

[0003] To overcome the shortcomings of the existing technology, this utility model provides a multi-angle contact resistance tester, which has the advantage of automatically adjusting the angle of the temperature controller.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-angle contact resistance tester, comprising: The fixing frame has a fixing plate fixedly installed on its outer surface; An adjustment mechanism is disposed on the outer surface of the fixed frame; The adjustment mechanism includes a motor, the top of which is fixedly connected to the bottom of the fixed plate. The output shaft of the motor is fixedly sleeved with a rotating shaft, and the top of the rotating shaft is fixedly sleeved with a rotating disk. A temperature controller is placed inside the rotating disk. An infrared emitter and a support arm are respectively arranged on the fixed frame. An infrared receiver is fixedly installed on the outer surface of the support arm, and the infrared emitter is located directly above the infrared receiver.

[0005] As a preferred embodiment of this utility model, a rotating disk is movably sleeved inside the outer surface of the rotating disk, and a circular hole is opened inside the rotating disk.

[0006] As a preferred embodiment of this utility model, a hinge block is fixedly installed inside the rotating disk, and a moving rod is hinged inside the hinge block.

[0007] As a preferred embodiment of this utility model, the end of the moving rod away from the hinge block is hinged to a movable rod, and the outer surface of the movable rod is movably connected to the inner surface of the outer surface of the rotating disk.

[0008] As a preferred embodiment of this utility model, a fixing block is fixedly installed at the bottom of the rotating disk, and a lever is slidably connected inside the fixing block.

[0009] As a preferred embodiment of this utility model, a plug is fixedly installed at the top of the paddle, the outer surface of the plug is movably connected to the inside of the top of the fixed block, and the top of the plug abuts against the bottom of the rotating disk.

[0010] As a preferred embodiment of this utility model, a spring is fixedly installed at the bottom end of the paddle, and the bottom end of the spring is fixedly connected to the interior of the fixing block.

[0011] As a preferred embodiment of this utility model, a fixing ring is fixedly installed at the bottom of the rotating disk, and an arc-shaped plate is slidably connected inside the fixing ring. The bottom end of the arc-shaped plate is fixedly connected to the outer surface of the fixing frame.

[0012] As a preferred embodiment of this utility model, a cylinder is fixedly installed at the top of the fixing frame, a moving block is fixedly installed at the output end of the cylinder, and a test end is fixedly installed at the bottom end of the moving block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This multi-angle contact resistance tester can automatically and quickly adjust the angle of the temperature controller without relying on the operator's experience and skill. It ensures precise alignment between the temperature controller contacts and the test terminals, avoiding angle deviations caused by manual operation. This guarantees stable and uniform contact between the temperature controller contacts and the test terminals, enabling stable transmission of the test current. This results in more accurate and reliable contact resistance test data. Furthermore, it significantly shortens the test preparation time for a single temperature controller, reduces the repetitive work of operators frequently adjusting the temperature controller angle, significantly reduces labor intensity, and lowers the risk of adjustment errors due to operator fatigue. This improves testing efficiency, effectively meets the urgent needs of enterprises for efficient testing, and strongly guarantees production rhythm. 2. This multi-angle contact resistance tester allows the operator to rotate a rotating disc to move four movable rods inward. When the movable rods contact the temperature controller, they provide a stable and reliable clamping and fixation of the temperature controller, ensuring its stability during the testing process. This prevents the temperature controller from shifting or loosening due to angle changes or external forces, effectively avoiding problems such as poor contact between the test terminals and contacts and abnormal test data caused by temperature controller position changes. This ensures the accuracy and reliability of the test data and further improves the testing precision. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 7 As shown, this utility model provides a multi-angle contact resistance tester, comprising: Fixing frame 1, with fixing plate 2 fixedly installed on the outer surface of fixing frame 1; The adjustment mechanism is located on the outer surface of the fixed frame 1; The adjustment mechanism includes a motor 3, the top of which is fixedly connected to the bottom of the fixed plate 2. The output shaft of the motor 3 is fixedly sleeved with a rotating shaft 4, and the top of the rotating shaft 4 is fixedly sleeved with a rotating disk 5. A temperature controller is placed inside the rotating disk 5. An infrared emitter 6 and a support arm 7 are respectively set on the fixed frame 1. An infrared receiver 8 is fixedly installed on the outer surface of the support arm 7, and the infrared emitter 6 is located directly above the infrared receiver 8.

[0018] When the infrared transmitter 6 is running, it will send infrared rays to the infrared receiver 8. When the infrared receiver 8 receives the infrared rays, it will send a signal to the motor 3 to make the motor 3 run. At this time, the rotating shaft 4 will drive the internal thermostat to rotate through the rotating disk 5. When the thermostat contact rotates to directly above the infrared receiver 8, it will block the infrared receiver 8, so that the infrared receiver 8 cannot receive the infrared rays emitted by the infrared transmitter 6. At this time, the infrared receiver 8 will stop sending signals to the motor 3, so that the motor 3 stops running.

[0019] Among them, a rotating disk 9 is movably sleeved inside the outer surface of the rotating disk 5, and a circular hole 14 is opened inside the rotating disk 9.

[0020] Because the rotating disk 9 is movably connected to the rotating disk 5, the rotating disk 9 can rotate around the connection point with the rotating disk 5 as the axis.

[0021] The rotating disk 9 has a hinge block 10 fixedly installed inside, and a moving rod 11 is hinged inside the hinge block 10.

[0022] When the rotating disk 9 rotates, it will simultaneously drive the four hinge blocks 10 to rotate. At this time, the four hinge blocks 10 will drive the four moving rods 11 to move respectively.

[0023] Among them, the end of the moving rod 11 away from the hinge block 10 is hinged to the movable rod 12, and the outer surface of the movable rod 12 is movably connected to the inner surface of the outer surface of the rotating disk 5.

[0024] When the four moving rods 11 move, they will drive the four movable rods 12 to move respectively. Since the movable rods 12 are movably connected to the rotating disk 5, the rotating disk 5 will limit the movement of the movable rods 12. At this time, the four movable rods 12 will move inward. When the four movable rods 12 come into contact with the thermostat during the movement, they will clamp and fix the thermostat.

[0025] Among them, a fixing block 15 is fixedly installed at the bottom of the rotating disk 5, and a paddle 16 is slidably connected inside the fixing block 15.

[0026] Due to the internal design of the fixing block 15, the movement of the paddle 16 is limited, so that the paddle 16 can only move up and down along the inside of the fixing block 15.

[0027] The top of the paddle 16 is fixedly mounted with a plug 17. The outer surface of the plug 17 is movably connected to the inside of the top of the fixed block 15. The top of the plug 17 abuts against the bottom of the rotating disk 9.

[0028] When the lever 16 moves up and down along the inside of the fixed block 15, it will simultaneously drive the insert block 17 to move up and down. When the round hole 14 rotates with the rotating disk 9 to the top of the insert block 17, if the lever 16 drives the insert block 17 to move upward, the insert block 17 will be inserted into the inside of the round hole 14. At this time, the insert block 17 will lock the rotating disk 9 as a whole. When the operator needs to remove the lock on the rotating disk 9, the operator can release the lock by moving the lever 16 to drive the insert block 17 downward.

[0029] Among them, a spring 18 is fixedly installed at the bottom end of the paddle 16, and the bottom end of the spring 18 is fixedly connected to the inside of the fixing block 15.

[0030] Due to the elastic force of the spring 18, the movement of the paddle 16 will be well reset. When the insert block 17 is directly below the round hole 14, the spring 18 will drive the insert block 17 to move upward through the paddle 16. When the paddle 16 drives the insert block 17 to move downward, it will compress the spring 18.

[0031] Among them, a fixing ring 19 is fixedly installed at the bottom of the rotating disk 9, and an arc plate 20 is slidably connected inside the fixing ring 19. The bottom end of the arc plate 20 is fixedly connected to the outer surface of the fixing frame 1.

[0032] When the rotating disk 9 rotates, it will drive the fixed ring 19 to rotate along the outer surface of the arc plate 20. Due to the design of the fixed ring 19 and the arc plate 20, the rotating disk 9 will be more stable when it rotates as a whole.

[0033] Among them, a cylinder 21 is fixedly installed at the top of the fixed frame 1, a moving block 22 is fixedly installed at the output end of the cylinder 21, and a test end 23 is fixedly installed at the bottom end of the moving block 22.

[0034] When the contact of the temperature controller is directly above the infrared receiver 8, the test terminal 23 will be directly above the contact. At this time, the operator starts the cylinder 21, which will cause the moving block 22 to drive the test terminal 23 downward. Then, the test terminal 23 will contact the contact during the downward movement and perform a resistance test on the temperature controller.

[0035] Working principle and usage process of this utility model: When the operator needs to perform a resistance test on the temperature controller, the operator first places the temperature controller inside the rotating disk 5. Then, the operator holds the two handles 13 and rotates the rotating disk 9 around the point where it engages with the rotating disk 5. During this process, the rotating disk 9 will cause the fixed ring 19 to rotate along the inside of the arc-shaped plate 20. Due to the design of the fixed ring 19 and the arc-shaped plate 20, the rotating disk 9 rotates more stably. At the same time, the four hinge blocks 10 will rotate under the influence of the rotating disk 9. Then, the four hinge blocks 10 will drive the four movable rods 12 through the four moving rods 11. Since the outer surface of the movable rods 12 is in movable engagement with the inside of the rotating disk 5, the four movable rods 12 will move along the rotating disk 5. The inside of the disc 5 moves inward, and then the four movable rods 12 will come into contact with the thermostat during the inward movement. At this time, the four movable rods 12 will simultaneously squeeze and push the thermostat to achieve the effect of fixing the thermostat. When the four movable rods 12 come into contact with the thermostat, the inside of the round hole 14 will align with the insert block 17 during rotation. Due to the elastic force of the spring 18, the spring 18 will drive the insert block 17 to move upward through the lever 16, so that the insert block 17 is inserted into the inside of the round hole 14. At this time, the insert block 17 will block the rotation of the entire rotating disc 9 through the round hole 14, so that the four movable rods 12 maintain the fixing effect on the thermostat, thereby realizing the function of conveniently fixing the thermostat.

[0036] The operator then simultaneously activates the infrared transmitter 6 and the infrared receiver 8. When the infrared transmitter 6 is running, it emits infrared rays to the infrared receiver 8. When the infrared receiver 8 receives the infrared rays, it sends a signal to the motor 3, causing the motor 3 to run. At this time, the rotating shaft 4 drives the rotating disk 5 to rotate. The temperature controller will then rotate under the influence of the rotating disk 5. When the two contacts on the temperature controller rotate to directly above the two infrared receivers 8, they will block the two infrared receivers 8, thus preventing the infrared rays emitted by the two infrared transmitters 6 from being received by the two infrared receivers 8. At this time, the two infrared receivers 8 will stop sending signals to the motor 3, causing the motor 3 to stop moving. At this time, the two contacts on the temperature controller will be directly below the two test terminals 23, thereby realizing the function of automatically adjusting the angle of the temperature controller. Then, the operator activates the cylinder 21. The output end of the cylinder 21 will drive the two test terminals 23 downward through the moving block 22. When the bottom of the two test terminals 23 contacts the temperature controller contacts, the resistance of the temperature controller will be tested.
