Description

Technical Field

[0001] The utility model relates to the technical field of terminal detection equipment, in particular to a terminal insulation and withstand voltage detection platform. Background Art

[0002] Terminals are parts that connect batteries to external conductors. In electrical engineering, terminals mostly refer to wiring terminals, also called wiring terminals. They are divided into single-hole, double-hole, socket, hook, etc., and materials include silver-plated copper, zinc-plated copper, copper, aluminum, iron, etc. Their main function is to transmit electrical signals or conduct electricity.

[0003] At present, the testing equipment for automatic insulation and withstand voltage testing of terminals in the prior art generally includes a testing table, on which are opened a number of positioning grooves evenly arranged around the circumference of the testing table. When testing the terminals, the staff feeds the terminals into the positioning grooves through a feeding mechanism, and controls the rotation of the testing table to drive the terminals to move to different positions for testing and material return. However, since the diameters and sizes of terminals of different models are also different, and the sizes of the positioning grooves are fixed, it is inconvenient for the staff to fix the terminals of different models when testing the terminals of different models, and thus it is inconvenient to test and process the terminals of different models. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a terminal insulation and withstand voltage testing station, which can solve the problem that the diameters and sizes of terminals of different models are different, and since the size of the positioning grooves is fixed, it is inconvenient for staff to fix the terminals of different models when testing the terminals of different models, and thus it is inconvenient to test and process the terminals of different models.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a terminal insulation and withstand voltage test bench, comprising a test bench base and a terminal fixing device; a servo motor is fixedly installed inside the test bench base, and the output end of the servo motor is fixedly connected to a rotating shaft; the terminal fixing device comprises a circular turntable, eight cylindrical blocks, a pressure block and a spring, the circular turntable is welded to the upper end of the rotating shaft, the eight cylindrical blocks are welded to the top of the circular turntable in a circular shape and equidistantly, a circular slide groove is opened at the bottom of the eight cylindrical blocks, the pressure block is slidably connected to the inside of the circular slide groove, the spring is fixedly connected to the top of the pressure block, and the end of the spring away from the pressure block is fixedly connected to the top wall of the circular slide groove.

[0006] Preferably, a circular groove is provided on the surface of the circular turntable, a wiring terminal is slidably engaged inside the groove, and a wiring circular hole is punched on the surface of the wiring terminal.

[0007] Preferably, the bottom of the pressing block is a hemispherical structure, and the bottom of the pressing block is slidably engaged in the inside of the wiring circular hole.

[0008] Preferably, a support frame is welded on the surface of the base of the detection platform, and a detector is fixedly installed on the top of the support frame.

[0009] Preferably, a support rod is welded on the surface of the base of the detection platform, and an arc-shaped pressing block is fixedly connected to the upper end of the support rod.

[0010] Preferably, the surface of the arc-shaped pressing block contacts the surface of the connecting terminal.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) In the terminal insulation withstand voltage test bench, when the terminal is completely slid into the slot, the spring releases its elastic force and pushes the pressing block to slide downward and squeeze into the inside of the wiring circular hole. Since the bottom of the pressing block is a hemispherical structure, the pressing block can be squeezed into the inside of wiring circular holes of different sizes through the hemispherical structure at the bottom, and then the terminal blocks of different models can be fixed by the pressing block, so that it is convenient for the staff to test and process the terminal blocks of different models.

[0013] (2) In the terminal insulation withstand voltage test bench, the circular turntable rotates through the card slot to drive the wiring terminal to rotate in a circular shape and gradually squeeze the surface of the arc-shaped pressing block. Since the size of the arc-shaped pressing block gradually increases toward the end close to the support rod, the wiring terminal is squeezed and dropped during the gradual sliding process on the surface of the arc-shaped pressing block to complete the material withdrawal. The squeezing effect of the arc-shaped pressing block can automatically withdraw the wiring terminal that has completed the test, thereby improving the degree of automation of the test bench and reducing the labor intensity of the staff.

[0024] See also Figure 1-4The utility model provides a technical solution: a terminal insulation and withstand voltage test bench, including a test bench base 1 and a terminal fixing device, a servo motor 2 is fixedly installed inside the test bench base 1, a rotating shaft 3 is fixedly connected to the output end of the servo motor 2, the terminal fixing device includes a circular turntable 4, eight cylindrical blocks 7, a pressure block 9 and a spring 10, the circular turntable 4 is welded to the upper end of the rotating shaft 3, the eight cylindrical blocks 7 are welded to the top of the circular turntable 4 in a circular and equidistant manner, the bottoms of the eight cylindrical blocks 7 are all provided with circular slide grooves 8, the pressure block 9 is slidably connected to the inside of the circular slide groove 8, the spring 10 is fixedly connected to the top of the pressure block 9, and one end of the spring 10 away from the pressure block 9 is fixedly connected to the top wall of the circular slide groove 8, the surface of the circular turntable 4 is provided with a card slot 5 in a circular shape, the inside of the card slot 5 is slidably carded with a terminal 6, the surface of the terminal 6 is stamped with a wiring circular hole 11, the bottom of the pressure block 9 is a hemispherical structure, and the bottom of the pressure block 9 is slidably carded to the inside of the wiring circular hole 11;

[0025] When the terminal insulation and withstand voltage test bench is in use, the staff only needs to insert the terminal 6 into the slot 5. After the terminal 6 enters the slot 5, the pressure block 9 can be squeezed and the pressure block 9 can slide upward inside the cylindrical block 7. The pressure block 9 slides upward to squeeze the spring 10. The spring 10 gives the pressure block 9 an elastic force downward. After the terminal 6 completely slides into the slot 5, the spring 10 releases the elastic force and pushes the pressure block 9 to slide downward and be squeezed into the wiring circular hole 11. Since the bottom of the pressure block 9 is a hemispherical structure, the pressure block 9 can be squeezed into the interior of the wiring circular holes 11 of different sizes through the hemispherical structure at the bottom, and then the different types of terminal blocks 6 can be fixed by the pressure block 9, which makes it convenient for the staff to detect and process the different types of terminal blocks 6.

[0026] A support frame 12 is welded on the surface of the detection table base 1, and a detector 13 is fixedly installed on the top of the support frame 12. A support rod 14 is welded on the surface of the detection table base 1, and an arc-shaped pressure block 15 is fixedly connected to the upper end of the support rod 14, and the surface of the arc-shaped pressure block 15 is in contact with the surface of the terminal 6.

[0027] The staff starts the servo motor 2, and the output end of the servo motor 2 rotates and drives the circular turntable 4 to rotate through the rotating shaft 3. The circular turntable 4 rotates and drives the terminal 6 to rotate to the lower position of the detector 13 through the card slot 5, and the detector 13 can be used to detect the welding point of the terminal 6. After the terminal 6 is detected, the servo motor 2 continues to drive the circular turntable 4 to rotate. The circular turntable 4 rotates through the card slot 5 to drive the terminal 6 to rotate in a circular shape and gradually squeeze the surface of the arc pressure block 15. Since the size of the arc pressure block 15 gradually increases toward the end close to the support rod 14, the terminal 6 is squeezed and dropped during the gradual sliding process on the surface of the arc pressure block 15 to complete the material withdrawal. The squeezing action of the arc pressure block 15 can make the detected terminal 6 automatically withdraw, thereby improving the automation degree of the detection platform and reducing the labor intensity of the staff.

[0028] Working principle: For the terminal insulation withstand voltage test bench, the staff only needs to insert the terminal 6 into the slot 5 to squeeze the pressing block 9, and make the pressing block 9 slide upward inside the cylindrical block 7 to squeeze the spring 10. When the terminal 6 completely slides into the slot 5, the spring 10 releases the elastic force and pushes the pressing block 9 to slide downward and squeeze inside the wiring circular hole 11. Since the bottom of the pressing block 9 is a hemispherical structure, the pressing block 9 can be squeezed into the interior of the wiring circular holes 11 of different sizes through the hemispherical structure at the bottom, and then the terminal 6 of different models can be fixed by the pressing block 9. The staff starts the servo motor 2, and the servo motor 2 drives the circular turntable 4 to rotate through the rotating shaft 3. The circular turntable 4 rotates and drives the terminal 6 to rotate to the lower position of the detector 13 through the card slot 5 for detection. After the detection of the terminal 6 is completed, the servo motor 2 continues to drive the circular turntable 4 to rotate. The rotation of the circular turntable 4 drives the terminal 6 to rotate in a circular shape and gradually squeezes the surface of the arc-shaped pressing block 15. The terminal 6 is squeezed and falls off during the gradual sliding process on the surface of the arc-shaped pressing block 15 to complete the material withdrawal. The squeezing effect of the arc-shaped pressing block 15 can make the detected terminal 6 automatically withdrawn.

[0029] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
