Description

Technical Field

[0001] The present invention relates to the technical field of plug strength detection, in particular to a socket plug strength detection device. Background Art

[0002] Strength testing of socket plugs is a key step to ensure their mechanical properties and electrical safety. It usually involves material, structure and durability testing. The durability test is to test the plug life of the plug. It simulates the long-term use of the plug through multiple plug-ins (such as 10,000 plug-ins). After the simulation is completed, the plug is tested to see whether it meets the plug force standard range and whether the contact resistance is .

[0003] During the aforementioned plug-in / plug-out life test, the plug-in / plug-out frequency must be controlled. This is because high-frequency continuous plug-in / plug-out can cause frictional heat to alter metal properties (such as elastic modulus), thereby interfering with durability data. Frequency control directly affects the duration of the life test. For example, if the plug-in / plug-out frequency is 6 to 10 seconds, 10,000 plug-in / plug-out cycles will require 16.7 to 27.8 hours, affecting the efficiency of multiple batch measurements. It also consumes a lot of energy and causes inconvenience for caregivers.

[0004] After searching, Chinese patent application CN110441152B discloses a strength detection device for socket plugs. Although it realizes automatic detection of the welding strength of the plugs, it cannot circumvent the above-mentioned problems. At the same time, it cannot adjust the cooling efficiency of the plugs according to the plug-in and unplugging frequency. If the cooling efficiency remains unchanged, the heat generated by friction cannot be dissipated in time during high-frequency plug-in and unplugging, so that the metal properties are still changed, thereby interfering with the durability data. During low-frequency plug-in and unplugging, the unchanged cooling efficiency will result in resource waste, reducing the degree of automation of the device and bringing inconvenience to the detection work.

[0025] See also Figure 9 The second transmission shaft 21 is socketed with the gear sleeve 24, the fixing frame 26 is arranged in a Y shape, the stop block 28 corresponds to the stop rod 29 one by one, and there are multiple stop blocks 28 and multiple stop rods 29, and the multiple stop blocks 28 and multiple stop rods 29 are evenly distributed about the central axis of the polygonal column 25.

[0026] See also Figure 6 and Figure 9 The end face of the gear sleeve 24 is slidably connected to the side wall of the fixing frame 26 , the contact surfaces of the stop block 28 and the stop rod 29 are both arc-shaped surfaces, and a one-way valve is installed on the outer surface of the sleeve 34 .

[0027] Specifically, during the process of plugging and unplugging the test plug 3 by the plug block 18, the motor 20 in the groove 41 is started, so that the second transmission shaft 21 on the motor 20 drives the sun gear 22 to rotate, so that the sun gear 22 drives the planetary gear 23 to rotate, so that the planetary gear 23 drives the gear sleeve 24 to rotate, so that the gear sleeve 24 drives one end of the first transmission belt 35 to rotate, so that the other end of the first transmission belt 35 drives the first propeller 36 to rotate, and then the first propeller 36 accelerates the flow of cooling water in the pump housing 16, so that the cooling water enters the cooling plate 15 and the lifting plate 9 through the inlet pipe 17, so that the cooling channels in the cooling plate 15 and the lifting plate 9 are filled with cooling water, thereby displacing the heat on the plug block 18 and the test plug 3, avoiding the influence of heat on the metal properties, avoiding interference with durability data, and enabling the plug-in life test to be performed at a high frequency without the need for long-term standby testing, thereby ensuring the efficiency of multiple batches of measurements and without consuming a large amount of energy. Example 3

[0028] See also Figure 5-Figure 9The present invention provides a technical solution: a strength detection device for a socket insert, wherein one end of a first transmission belt 35 is fixedly connected to the end surface of the gear sleeve 24, and the other end of the first transmission belt 35 is fixedly connected to a first propeller 36, and the outer surface of the first transmission shaft 11 is fixedly connected to one end of a second transmission belt 37, and the other end of the second transmission belt 37 is fixedly connected to a second propeller 38, and the end surface of the second propeller 38 is rotatably connected to the side wall of the inner cavity 39, and one end of a pull rod 33 is slidably sleeved in the sleeve 34, and the other end of the pull rod 33 is fixedly connected to the movable plate 32, and the outer surface of the sleeve 34 is connected to one end of an air guide tube 40, and the other end of the air guide tube 40 is connected to the inner cavity 39.

[0029] See also Figure 5 and Figure 7-Figure 9 A sealing ring is provided at the end of the sleeve 34, and the sealing ring is slidably connected to the pull rod 33, the first transmission belt 35 is connected to the second transmission shaft 21, and the first transmission belt 35 is slidably connected to the pump casing 16, the second transmission belt 37 is slidably connected to the main body 1, and the two ends of the first propeller 36 are rotatably connected to the two ends of the pump casing 16.

[0030] Specifically, in the process of adjusting the plugging and unplugging frequency, the first transmission shaft 11 drives one end of the second transmission belt 37 to rotate faster, so that the other end of the second transmission belt 37 accelerates the rotation speed of the second propeller 38, so that the second propeller 38 accelerates the flow of gas in the inner cavity 39, so that the efficiency of air entering the sleeve 34 through the air guide tube 40 is improved, so that the gas filled in the end of the sleeve 34 is much greater than the gas lost by the one-way valve, so that the air pressure at the end of the sleeve 34 increases, thereby pushing the pull rod 33 to translate, so that the pull rod 33 compresses the air at the other end of the sleeve 34 until the air pressure at both ends of the pull rod 33 is balanced, at this time the position of the pull rod 33 is re-fixed, and in the process of the translation of the pull rod 33, the restriction of the movable plate 32 on the pull rod 33 on the compression spring 31 is reduced, so that the compression spring 31 returns, reducing the translation restriction of the compression spring 31 on the pressure plate 30, and at this time the baffle 29 on the pressure plate 30 can translate. The force of the rod 29 that blocks the rotation of the block 28 is reduced, and the block 28 is fixed to the planetary carrier 27, that is, when the torque limit of the planetary carrier 27 is reduced, when the speed of the sun gear 22 is constant, the torque limit of the planetary carrier 27 and the output speed of the gear sleeve 24 are inversely proportional, that is, the torque limit of the planetary carrier 27 is reduced, and the speed of the gear sleeve 24 and the first transmission belt 35 is increased. According to the above principle, the increase in the speed of the first transmission belt 35 directly accelerates the flow efficiency of the cooling water, further accelerates the heat replacement efficiency, and improves the cooling efficiency of the test plug 3 and the plug 18, and vice versa. Therefore, the cooling efficiency of the test plug 3 can be adjusted according to the plug-in frequency. When plugging and unplugging at a high frequency, the cooling efficiency is improved, and the heat generated by friction can be dissipated in time, so that the metal properties remain unchanged, ensuring the accuracy of the durability data. When plugging and unplugging at a low frequency, the cooling efficiency is reduced, avoiding waste of resources and improving the degree of automation of the device.

[0031] The working principle and usage process of the present invention are as follows: when it is necessary to test the strength of the socket plug, the input end of the pump housing 16 and the output end of the output pipe 19 are both connected to an external pipeline, and then the test plug 3 is inserted into the top surface of the main body 1, so that the bottom end of the test plug 3 enters the sliding cavity 2, and then the rotating shaft 4 on the main body 1 is rotated, so that the rotating shaft 4 drives the clamping block 6 to move in opposite directions through the bidirectional thread 5, so that the clamping block 6 clamps the bottom end of the test plug 3 to complete the fixation of the test plug 3. The above process can place multiple test plugs 3 at the same time and complete the fixation of multiple test plugs 3 synchronously, simplifying the fixing process of the test plug 3, and the tightening degree is the same. If the tightening degree is different, the state of the test plug 3 when the plug block 18 is plugged in and out is different, thereby increasing the experimental variables and affecting the detection result of the test plug 3; After the test plug 3 is fixed, the cooling plate 15 is inserted into the test plug 3 so that the cooling plate 15 is in close contact with the test plug 3. At the same time, the end of the cooling plate 15 is engaged with the main body 1 to complete the fixing of the cooling plate 15. At this time, the motor 10 on the main body 1 is started again, so that the first transmission shaft 11 on the motor 10 drives the turntable 12 to rotate, so that the turntable 12 drives the bottom end of the connecting rod 13 to revolve, so that the height of the connecting rod 13 in the vertical direction changes, so that the connecting rod 13 drives the top rod 14 to reciprocate up and down, so that the lifting plate 9 on the top rod 14 reciprocates and rises and falls, and then the plug block 18 on the lifting plate 9 plugs in and out the test plug 3, simulating the long-term use of the test plug 3. When the plugging and unplugging frequency needs to be changed, the plugging and unplugging frequency can be adjusted by adjusting the output speed of the motor 10; When the above-mentioned plug block 18 is plugging and unplugging the test plug 3, the motor 20 in the groove 41 is started, so that the second transmission shaft 21 on the motor 20 drives the sun gear 22 to rotate, so that the sun gear 22 drives the planetary gears 23 to rotate, so that the planetary gears 23 drive the gear sleeve 24 to rotate, so that the gear sleeve 24 drives one end of the first transmission belt 35 to rotate, so that the other end of the first transmission belt 35 drives the first propeller 36 to rotate, and then the first propeller 36 accelerates the flow of cooling water in the pump housing 16, so that the cooling water enters the cooling plate 15 and the lifting plate 9 through the inlet pipe 17, so that the cooling channels in the cooling plate 15 and the lifting plate 9 are filled with cooling water, thereby displacing the heat on the plug block 18 and the test plug 3, avoiding the influence of heat on the metal properties and avoiding interference with the durability data, so that the plug-in life test can be carried out at a high frequency without the need for long-term standby testing, ensuring the efficiency of multiple batch measurements, and without consuming a lot of energy; The adjustment of the output speed of the above-mentioned motor 10 directly affects the speed of the first transmission shaft 11, that is, the higher the plugging and unplugging frequency, the faster the speed of the first transmission shaft 11, and vice versa. When the speed of the first transmission shaft 11 is accelerated, the first transmission shaft 11 drives one end of the second transmission belt 37 to rotate faster, so that the other end of the second transmission belt 37 accelerates the speed of the second propeller 38, so that the second propeller 38 accelerates the flow of gas in the inner cavity 39, so that the efficiency of air entering the sleeve 34 through the air guide tube 40 is improved, so that the gas filled in the end of the sleeve 34 is much greater than the gas lost from the one-way valve, so that the air pressure at the end of the sleeve 34 increases, thereby pushing the pull rod 33 to translate, so that the pull rod 33 compresses the air at the other end of the sleeve 34 until the air pressure at both ends of the pull rod 33 is balanced. At this time, the position of the pull rod 33 is re-fixed, and in the process of translation of the pull rod 33, the restriction of the movable plate 32 on the pull rod 33 on the compression spring 31 is reduced, so that the compression spring 31 returns, reducing the pressure of the compression spring 31 on the pressure plate 30 The translation limit, at this time the stop rod 29 on the pressure plate 30 can be translated, so that the force of the stop rod 29 blocking the rotation of the stop block 28 is reduced, and the stop block 28 is fixed to the planetary carrier 27, that is, when the torque limit of the planetary carrier 27 is reduced, when the speed of the sun gear 22 is constant, the torque limit of the planetary carrier 27 and the output speed of the gear sleeve 24 are inversely related, that is, the torque limit of the planetary carrier 27 is reduced, and the speed of the gear sleeve 24 and the first transmission belt 35 is increased. According to the above principle, the increase in the speed of the first transmission belt 35 directly accelerates the flow efficiency of the cooling water, further accelerates the heat replacement efficiency, and improves the cooling efficiency of the test plug 3 and the plug 18, and vice versa. Therefore, the cooling efficiency of the test plug 3 can be adjusted according to the plug-in frequency. When the plug-in frequency is high, the cooling efficiency is improved, and the heat generated by friction can be dissipated in time, so that the metal properties remain unchanged, ensuring the accuracy of the durability data. When the plug-in frequency is low, the cooling efficiency is reduced, avoiding waste of resources, improving the degree of automation of the device, and completing the operation.
