Abstract
Description
Technical Field
[0001] This utility model relates to the field of capacitor testing machine technology, specifically a capacitor testing machine with precise positioning. Background Technology
[0002] The working principle of a precision-positioning capacitor tester is mainly to apply voltage to charge and discharge the capacitor, and measure its relevant electrical parameters, such as charging and discharging current and voltage changes. This allows for the calculation of parameters such as capacitance and error, and enables precise positioning of the capacitor. Specifically, when the capacitor tester is working, it first connects the capacitor to be tested to the test circuit. Then, by applying a certain voltage, the capacitor undergoes a charging and discharging process.
[0003] Reference patent (Publication No.: CN222070735U; Publication Date: 2024-11-26) discloses a capacitor testing machine, relating to the field of testing equipment technology. It includes a cover, with testing components rotatably connected to the bottom of both sides of the cover. A snap-fit block is fixedly connected to the top center of the cover. A tool clamp is provided on the inner wall of the testing component, and two positive and negative detection lines are provided on the inner wall of the testing component, with the positive and negative detection lines located on the right side of the tool clamp. Support components are fixedly connected to the left and right sides and front and rear of the testing component. The dampers and springs fixedly connected to the bottom of the testing unit provide shock absorption when the buffer seat is under force. The support frames fixedly connected to the left and right sides of the front and rear support rods utilize a rotating shaft and a fixing knob to rotate and drive the lower support rods to provide bottom support. The upper rotating support rods can also serve as a handle.
[0004] Based on the aforementioned patent, the positive and negative detection lines of the precision-positioned capacitor tester are mainly used to connect capacitors and transmit test signals to ensure accurate measurement of capacitor performance. However, the positive and negative detection lines are not easy to store, and are prone to becoming scattered and tangled. This not only affects the cleanliness of the testing environment but also reduces work efficiency. Furthermore, it is inconvenient to carry and store the tester and to clamp and fix the testing equipment. Therefore, this utility model provides a precision-positioned capacitor tester. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a precision-positioning capacitor tester. It solves the problem that the positive and negative detection lines of a precision-positioning capacitor tester are primarily used to connect capacitors and transmit test signals to ensure accurate measurement of capacitor performance. However, these detection lines are inconvenient to store, easily becoming tangled and knotted. This not only affects the cleanliness of the testing environment but also reduces work efficiency. Furthermore, it makes the tester difficult to carry and store, and hinders the clamping and securing of the tested equipment.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a precision-positioning capacitor testing machine, comprising a testing machine body, wherein the testing machine body is provided with a mounting mechanism for testing capacitor equipment, the mounting mechanism comprising:
[0007] The storage assembly includes a cover that is rotatably connected to the upper edge of the main body of the test machine via a rotating shaft. Two sets of storage shells are fixed inside the main body of the test machine. A storage rod is fixed inside the storage shell. Positive and negative detection lines are wound around the outer wall of the storage rod. A sliding groove is opened through the side wall of the storage shell. A clamping ring connected by a sliding assembly is provided inside the sliding groove.
[0008] The clamping assembly includes a positioning rod fixed to the inner wall of the cover, a limiting plate connected to the outer wall of the positioning rod by a threaded assembly, a fixing plate fixed to the inner wall of the limiting plate, and a clamping plate connected to the inner wall of the fixing plate by an elastic assembly.
[0009] Preferably, the sliding assembly includes a slider that is slidably connected inside the sliding groove, a clamping ring that is fixedly connected to the upper end face of the slider, two sets of sliders that are symmetrically distributed about the clamping ring, and a threaded bolt connected to the inside of the slider.
[0010] Preferably, the upper end face of the cover is fixed with two sets of carrying brackets, and the inside of the carrying brackets is provided with an arc-shaped groove for carrying.
[0011] Preferably, the front end face of the cover is fixed with a bonding plate, and the bonding plate is internally threaded with a locking bolt.
[0012] Preferably, the threaded assembly includes a bidirectional screw rotatably connected to the inner wall of the cover, a limiting plate slidably connected to the outer wall of the positioning rod, and the limiting plate and the bidirectional screw are threadedly connected.
[0013] Preferably, the elastic component includes a spring fixed to the inner wall of a fixed plate, a clamping plate fixedly connected to one end of the spring, and a telescopic sleeve rod provided on the inner ring of the spring, with both ends of the telescopic sleeve rod being fixedly connected to the clamping plate and the fixed plate, respectively.
[0014] Beneficial effects
[0015] This invention provides a capacitor testing machine with precise positioning. Compared with the prior art, it has the following advantages:
[0016] Firstly, this invention places the capacitor device between two sets of limiting plates. Then, a bidirectional screw rotates via a micro motor, causing the two sets of limiting plates to open and close at intervals along the positioning rod via the bidirectional screw, thereby clamping the capacitor device. The clamping plates are compressed on the fixed plate by springs and telescopic sleeves for further limiting and clamping the capacitor device, ensuring its positional stability during testing and thus improving testing accuracy. By opening and closing the limiting plates at intervals, it can accommodate capacitor devices of different specifications, improving the versatility and flexibility of the testing machine.
[0017] Secondly, when storing positive and negative test cables, this utility model involves winding the test cables around the outer wall of the storage rod inside the storage housing. Then, the clamping ring slides downwards along the groove on the storage housing via the sliders on both sides. The wound test cables are then pressed and clamped downwards, and the threaded bolt is rotated to lock them to the bottom of the testing machine body. This effectively prevents the test cables from becoming tangled or knotted during testing, making the testing environment neater and more orderly, improving work efficiency. It is not only easy to organize but also easy to carry and store. By neatly winding the positive and negative test cables around the storage rod and locking them to the bottom of the testing machine body, the space occupied by the testing machine can be greatly reduced, making the testing machine more portable.
