Description

Technical Field

[0001] The present invention relates to the technical field of distribution box detection, and in particular to a distribution box strength deformation detection device and a use method thereof. Background Art

[0002] A distribution box is a low-voltage distribution device that is assembled in a closed or semi-closed metal cabinet or on a screen according to electrical wiring requirements by assembling switchgear, measuring instruments, protective electrical appliances and auxiliary equipment. It is widely used in industrial, commercial, residential and other places to provide power distribution and protection for various electrical equipment to ensure the safety and stability of power supply. The strength of the distribution box refers to the ability of the distribution box to resist damage and deformation when subjected to various external forces. This performance is crucial to ensuring the normal operation of the distribution box and the safety of internal electrical components.

[0003] In the existing strength and deformation test of the distribution box, since the door of the distribution box is more likely to be damaged by impact after installation, the door and the back of the distribution box need to be strength tested during the strength and deformation test. At the same time, after the distribution box is installed, in the actual use environment, the impact conditions that the door of the distribution box may be subjected to vary, and the shapes of the impact objects that hit the door of the distribution box are also different. When impact objects of different shapes hit or impact the distribution box, the degree of strength deformation of the distribution box after the impact and impact is different. Most of the existing detection methods are single press-type detection, which results in the detection results being only referenceable in certain cases. At the same time, there is a lack of detection of side deformation during testing, which makes it inconvenient to carry out targeted reinforcement design of the distribution box based on the data after the test. Therefore, the present application provides a distribution box strength and deformation detection device and a method for use to meet the needs. Summary of the invention

[0027] like Figures 1 to 11 As shown, an embodiment of the present invention provides a distribution box strength deformation detection device, including a device box 1, a sealing door 2 is installed on the surface of the device box 1, a collection box 20 is nested and installed at the bottom of the inner wall of the device box 1, a control module 3 is installed on one side of the surface of the device box 1, a hydraulic cylinder 4 is installed on the top of the inner wall of the device box 1, a test pressure plate 5 is connected to the bottom of the hydraulic cylinder 4, a sensor 50 is nested and installed at the bottom of the test pressure plate 5, an electric slide rail 6 is installed at the bottom of the inner wall of the device box 1, the number of the electric slide rails 6 is set to two groups, and two groups of sliding bases 7 are sleeved on the top of the two groups of electric slide rails 6. A motor 8 and a trigger assembly 9 are installed on the top of one group of sliding bases 7. A trigger assembly 9 is installed between the two groups of sliding bases 7. The trigger assembly 9 is used to trigger the loading and unloading operations of the distribution box to be tested. A positioning assembly 10 is installed on the top of the trigger assembly 9. The positioning assembly 10 is used to position and clamp the distribution box to be tested. A switching assembly 11 is installed on the top of the test pressure plate 5. The switching assembly 11 is used to switch the test mode of the distribution box. The positioning assembly 10 is located at the top of the trigger assembly 9, and the switching assembly 11 is located above the trigger assembly 9 and the positioning assembly 10.

[0028] By setting the trigger component 9 and cooperating with the effect of the positioning component 10, the detection switching effect between the door and the back of the distribution box to be tested is achieved. By setting the positioning component 10, the distribution box to be tested is clamped around the box body to achieve the clamping and limiting effect of the distribution box to be tested. By setting the switching component 11, the impact at the door position of the distribution box is simulated by the punch head 1110. The punch heads 1110 of different sizes and shapes can be replaced to improve the flexibility in performing strength deformation detection on the door and back of the distribution box.

[0029] like Figure 5 to Figure 6 As shown, the trigger assembly 9 includes a rotating base 91, which is installed between two groups of sliding bases 7. One end of the rotating base 91 extends out of one end of one group of sliding bases 7 and is connected to the motor 8. A positioning groove 92 is provided at the bottom of the rotating base 91. A one-way gear 93 is nested and installed on one side of the rotating base 91. One end of the one-way gear 93 extends out of the rotating base 91 and is connected to one end of a rotating rod 102. A one-way gear 2 94 is installed on the other side of the rotating base 91. One end of the one-way gear 2 94 extends out of the rotating base 91 and is connected to the other end of the rotating rod 102. The trigger assembly 9 also includes a rack 95. The number of the racks 95 is set to two groups. The two groups of racks 95 are respectively installed on both sides of the inner wall of the equipment box 1, and the two groups of racks 95 are respectively meshed with the one-way gear 1 93 and the one-way gear 2 94.

[0030] The operator first places the distribution box to be tested in the positioning groove 92 at the bottom end of the rotating base 91, so that the box door of the distribution box to be tested is placed upwards, and one side of the distribution box to be tested contacts the inner wall of the two sets of reference positioning blocks 101. Then the control module 3 controls the electric slide rail 6 to start. Under the action of the electric slide rail 6, the two sets of sliding bases 7 slide along the two sets of electric slide rails 6. When the two sets of sliding bases 7 slide, they drive the rotating base 91 and the distribution box to be tested placed in the positioning groove 92 to slide synchronously, so that the distribution box to be tested reaches the bottom of the test pressure plate 5; During this process, the rotating base 91 drives the one-way gear 1 93 to slide synchronously. The one-way gear 1 93 slides and passes through one of the racks 95. Under the action of the racks 95, the one-way gear 1 93 rotates synchronously. The one-way gear 1 93 rotates and drives the rotating rod 102 to rotate synchronously. When the strength deformation test on the back of the distribution box is completed, the two sets of sliding bases 7 continue to slide along the two sets of electric slide rails 6. The two sets of sliding bases 7 slide while driving the rotating base 91 to slide synchronously, so that the rotating base 91 is close to the top of the collection box 20. The rotating base 91 slides while driving the one-way gear 2 94 on the other side to approach and mesh with the other set of racks 95. Under the action of the other set of racks 95, the one-way gear 2 94 produces a reverse rotation effect. The one-way gear 2 94 rotates in the reverse direction while driving the rotating rod 1 102 to rotate in the reverse direction. Subsequently, the control module 3 controls the motor 8 to start. After the motor 8 is started, it drives the rotating base 91 to rotate 180 degrees in the opposite direction to reset. At the same time, the two groups of sliding bases 7 slide in opposite directions along the two groups of electric slide rails 6. When the sliding base 7 slides, it drives the rotating base 91 and the positioning groove 92 to approach the sealed door 2, making it convenient for the operator to continue to put in the next group of distribution boxes to be tested.

[0031] By setting the rotation coordination of the rotating base 91 and the motor 8 and cooperating with the effect of the positioning assembly 10, the detection switching effect between the box door and the back of the distribution box to be tested is achieved. At the same time, the rotation effect of the rotating base 91 is coordinated to trigger and release the clamping effect of the positioning assembly 10. The mechanism is simple and easy to maintain.

[0032] like Figure 7 and Figure 8 As shown, the positioning assembly 10 includes a reference positioning block 101, the number of the reference positioning blocks 101 is set to two groups, and the two groups of reference positioning blocks 101 are both installed on the top of the rotating base 91. A rotating rod 102 is installed on one side of the two groups of reference positioning blocks 101. The surface of the rotating rod 102 is sleeved with two groups of bevel gears 103. One side of the bevel gear 103 is meshed with a bevel gear 2 104. The number of the bevel gear 2 104 is set to two groups. The two groups of bevel gears 2 104 are both installed on one side of the two groups of reference positioning blocks 101. One end of the bevel gear 2 104 is connected to a screw rod 105. The number of the screw rod 105 is set to two groups. The two groups of screw rods 105 are both installed on the top of the rotating base 91. The outer surface of the screw rod 105 is threadedly sleeved with a sliding sleeve 106 A sliding positioning block 107 is installed at one end of the sliding sleeve 106, and the number of the sliding positioning blocks 107 is set to two groups. The two groups of sliding positioning blocks 107 are both installed at one end of the sliding sleeve 106. Two groups of elastic telescopic rods 108 are respectively installed on the top of the two groups of reference positioning blocks 101 and the sliding positioning blocks 107. The positioning component 10 also includes a sensor 109. The number of the sensor 109 is set to multiple groups. Two of the multiple groups of sensor 109 are respectively installed between the two groups of reference positioning blocks 101 and the two groups of sliding positioning blocks 107, and the remaining two groups of sensor 109 are respectively installed between the two groups of reference positioning blocks 101 and the two groups of elastic telescopic rods 108 on the top of the sliding positioning blocks 107.

[0033] When the rotating rod 102 rotates, the two groups of bevel gears 103 on the surface rotate synchronously. When the bevel gear 103 rotates, the meshing bevel gear 2 104 rotates. When the bevel gear 2 104 rotates, the screw 105 at one end rotates synchronously. Under the rotation of the screw 105, the sliding sleeve 106 threadedly sleeved on the outer surface of the screw 105 slides along the direction of the screw 105. When the sliding sleeve 106 slides, the sliding positioning block 107 slides synchronously. Under the rotation of the two groups of screws 105, the two groups of sliding positioning blocks 107 slide synchronously close to the two groups of reference positioning blocks. The positioning block 101 makes the two groups of sliding positioning blocks 107 approach and contact the other side of the distribution box to be tested. Through the cooperation between the two groups of reference positioning blocks 101 and the two groups of sliding positioning blocks 107, the positioning and clamping effect of the distribution box to be tested is achieved. When one group of sliding positioning blocks 107 slides, the elastic telescopic rod 108 at the top is squeezed to contract. Through the elastic cooperation between one group of reference positioning blocks 101 and the two groups of elastic telescopic rods 108 at the top of the sliding positioning block 107, the sensor 2 109 can adapt to the change of the distance between the reference positioning block 101 and the sliding positioning block 107; Then the control module 3 controls the hydraulic cylinder 4 to start, and after the hydraulic cylinder 4 starts, it pushes the test platen 5 downward, so that the test platen 5 contacts and squeezes the top surface of the distribution box to be tested, and changes the thrust of the hydraulic cylinder 4 according to the test requirements. In this process, the strength deformation of the side of the distribution box to be tested is recorded by multiple sets of sensors 109, so as to realize the strength deformation detection of the side of the distribution box to be tested; When the strength deformation detection of the door of the distribution box is completed, the control module 3 controls the motor 8 to start, and the motor 8 drives the rotating base 91 to rotate 180 degrees. When the rotating base 91 rotates, the reference positioning block 101 and the sliding positioning block 107 clamp the distribution box, and synchronously drives the distribution box to rotate 180 degrees, so that the back of the distribution box changes from the downward state to the upward state; Similarly, the control module 3 controls the hydraulic cylinder 4 to start up again and pushes the test platen 5 downward, and the hydraulic cylinder 4 pushes the punch head 1110 to punch the back of the distribution box to simulate the strength deformation of the back of the distribution box when objects of different shapes hit the back of the distribution box. At the same time, the sensor 50 at the bottom of the test platen 5 detects the strength deformation data of the back of the distribution box. When the rotating rod 102 rotates in the opposite direction, it drives the two groups of bevel gears 103 on the surface to rotate in the opposite direction synchronously. When the bevel gear 103 rotates in the opposite direction, it engages with the bevel gear 2 104 to rotate. When the bevel gear 2 104 rotates in the opposite direction, it drives the screw 105 at one end to rotate in the opposite direction synchronously. Under the action of the reverse rotation of the screw 105, the sliding sleeve 106 threadedly sleeved on the outer surface of the screw 105 slides in the opposite direction along the direction of the screw 105. When the sliding sleeve 106 slides, it drives the sliding positioning block 107 to slide in the opposite direction synchronously. Under the rotation action of the two groups of screws 105, the two groups of sliding positioning blocks 107 slide synchronously away from the two groups of reference positioning blocks 101, so that the two groups of sliding positioning blocks 107 are out of contact with the other side of the distribution box. At this time, the distribution box falls into the collection box 20 under the action of its own weight and gravity, so that the distribution box after the inspection is collected.

[0034] By setting the rotation effect of rotating rod 102, bevel gear 103 and bevel gear 2 104, and coordinating the sliding cooperation of screw rod 105 and sliding sleeve 106, the clamping and limiting effect of the distribution box to be tested is achieved, and the strength deformation of the side position of the distribution box to be tested is detected by multiple sets of sensors 2 109. While ensuring the clamping effect of the reference positioning block 101 and the sliding positioning block 107 on the distribution box to be tested, the detection accuracy of the multiple sets of sensors 2 109 on the side strength deformation of the distribution box is guaranteed.

[0035] like Figures 9 to 11 As shown, the switching assembly 11 includes a mounting frame 111, and multiple sets of elastic telescopic rods 112 are installed on the side of the mounting frame 111. The bottom ends of the multiple sets of elastic telescopic rods 112 are elastically installed at the top edge of the test pressure plate 5.

A screw rod 115 is installed at the bottom end of the turntable 114. A positioning ring 1150 is threadedly sleeved on the surface of the screw rod 115. The positioning ring 1150 is installed at the edge of one side of the top of the test pressure plate 5. A mounting groove 116 is installed on one side of the mounting frame 111. The number of the mounting grooves 116 is set to multiple groups, and the multiple sets of mounting grooves 116 are arranged in an array on one side of the mounting frame 111. Arrangement, a mounting plate 117 is installed on the inner wall of the mounting groove 116 by bolts, a rotating rod 118 is installed on one side of the mounting plate 117, the other end of the rotating rod 118 is plugged into the inner wall of the mounting frame 111, a mounting ring 119 is sleeved on the surface of the rotating rod 118, the number of the mounting rings 119 is set to multiple groups, and the multiple groups of mounting rings 119 are arranged in an array on the surface of the rotating rod 118, and punch heads 1110 are movably inserted on both sides of the mounting rings 119, a ratchet 1111 is sleeved on the surface of one side of the rotating rod 118, one end of the ratchet 1111 contacts with a pawl 1112, and the pawl 1112 is installed on the other side of the mounting plate 117, and a rotating disk 1113 is installed on one end of the rotating rod 118.

[0036] When the strength deformation test on the side of the distribution box is completed, the hydraulic cylinder 4 drives the test platen 5 to slide and reset, so that the bottom end of the test platen 5 is out of contact with the top of the distribution box to be tested. The operator first rotates the rotating disk 1113 to make the rotating disk 1113 drive the rotating rod 118 to rotate synchronously. When the rotating rod 118 rotates, it drives the mounting ring 119 arranged in the surface array to rotate synchronously, so that the two groups of punching heads 1110 arranged horizontally on both sides of the mounting ring 119 are converted from a horizontal state to a vertical state. When the rotating rod 118 rotates, it drives the ratchet 1111 to rotate synchronously. When the ratchet 1111 rotates, it pushes open the pawl 1112. After the rotating rod 118 and the ratchet 1111 stop rotating, the ratchet 1111 is limited by the pawl 1112.

[0037] The operator then rotates the turntable 114, and the turntable 114 drives the screw rod 115 to rotate synchronously. The screw rod 115 rotates on the inner wall of the positioning ring 1150 and rotates downward along the direction of the positioning ring 1150. The screw rod 115 is pressed downward and drives the installation frame 111 to slide downward through the collar 113. The installation frame 111 slides and squeezes the multiple sets of elastic telescopic rods 112 to contract, so that the bottom end of the installation frame 111 approaches and contacts the top of the rotating base 91. The installation frame 111 approaches the top of the rotating base 91 and brings The movable mounting groove 116 and the mounting plate 117 in the mounting groove 116 slide downward synchronously to approach the rotating base 91. The mounting plate 117 slides along with the mounting frame 111, while driving the rotating rod 118, the mounting ring 119, and the punch head 1110 to slide downward synchronously. At this time, the two groups of punch heads 1110 on both sides of the mounting ring 119 are in a vertical state. Under the sliding action of the mounting frame 111, one group of the punch heads 1110 approaches and passes through the opening at the bottom end of the rotating base 91, and extends out from the opening at the bottom end of the rotating base 91.

[0038] Subsequently, the control module 3 controls the hydraulic cylinder 4 to start. After the hydraulic cylinder 4 is started, it pushes the test platen 5 downward. When the test platen 5 is pressed downward, it drives the installation frame 111 to slide downward synchronously. When the installation frame 111 slides, the clamping effect between the installation groove 116 and the installation plate 117 drives the installation plate 117 and the rotating rod 118 to slide downward synchronously. When the rotating rod 118 slides, it drives the installation ring 119 and the punch head 1110 to approach and contact the door of the distribution box to be tested. The punch head 1110 is pushed by the hydraulic cylinder 4 to punch the door position of the distribution box to simulate the strength deformation of the distribution box door when objects of different shapes hit the door position of the distribution box. At the same time, the strength deformation data of the door of the distribution box is detected by the sensor 150 at the bottom of the test platen 5.

[0039] At the same time, when the punch head 1110 is used to impact the back and door position of the distribution box, the operator can use the tool to unscrew the bolts to release the fixing state between the mounting groove 116 and the mounting plate 117. Then the operator can pull the mounting plate 117 out of the mounting groove 116 and disengage one end of the rotating rod 118 from the inner wall of the mounting frame 111, and replace the punch heads 1110 on both sides of the mounting ring 119 according to the strength deformation test requirements.

[0040] By changing the distance between the mounting frame 111 and the test platen 5, multiple sets of punch heads 1110 are extended from the bottom end of the test platen 5. The punch heads 1110 are used to simulate the impact at the door of the distribution box. At the same time, when testing the door of the distribution box, punch heads 1110 of different sizes and shapes are replaced according to different simulation requirements, thereby improving the flexibility in performing strength deformation detection on the door and back of the distribution box.

[0041] The present application also provides a method for using a distribution box strength deformation detection device, the method comprising the following steps: S1. The operator first opens the sealed door 2 and places the distribution box to be tested into the positioning groove 92 at the top of the rotating base 91. The control module 3 controls the electric slide rail 6 to start, so that the rotating base 91 reaches the bottom of the test platen 5. In this process, the distribution box to be tested is positioned and clamped through the cooperation of the trigger component 9 and the positioning component 10; S2, the control module 3 controls the hydraulic cylinder 4 to start, and performs an extrusion test on the top of the distribution box to be tested through the test plate 5, and records the strength deformation data of the side position of the distribution box to be tested through the multiple sets of sensors 109 in the positioning component 10; S3, the operator changes the distance between the mounting frame 111 and the test platen 5 through the switching assembly 11, and at the same time switches the horizontal state of the punch heads 1110 on both sides of the mounting ring 119, so that the punch heads 1110 extend from the bottom end of the test platen 5; S4, the control module 3 controls the motor 8 to start, and the motor 8 drives the rotating base 91 to rotate 180 degrees. Through the rotation effect of the rotating base 91 and the switching effect of the switching component 11, the stamping detection switching of the two positions of the distribution box door and the back to be detected is realized.

[0042] The working principle of the technical solution provided by the present invention is as follows: The operator first places the distribution box to be tested in the positioning groove 92 at the bottom end of the rotating base 91, with the door of the distribution box to be tested facing upwards, and one side of the distribution box to be tested contacts the inner walls of the two sets of reference positioning blocks 101. Then the control module 3 controls the electric slide rail 6 to start. Under the action of the electric slide rail 6, the two sets of sliding bases 7 slide along the direction of the two sets of electric slide rails 6. When the two sets of sliding bases 7 slide, they drive the rotating base 91 and the distribution box to be tested placed in the positioning groove 92 to slide synchronously, so that the distribution box to be tested reaches under the test pressure plate 5.

[0043] During this process, the rotating base 91 drives the one-way gear 1 93 to slide synchronously. The one-way gear 1 93 slides and passes through one of the sets of racks 95. Under the action of the racks 95, the one-way gear 1 93 rotates synchronously. When the one-way gear 1 93 rotates, it drives the rotating rod 102 to rotate synchronously.

[0044] When the rotating rod 102 rotates, the two groups of bevel gears 103 on the surface rotate synchronously. When the bevel gear 103 rotates, the meshing bevel gear 2 104 rotates. When the bevel gear 2 104 rotates, the screw 105 at one end rotates synchronously. Under the rotation of the screw 105, the sliding sleeve 106 threadedly sleeved on the outer surface of the screw 105 slides along the direction of the screw 105. When the sliding sleeve 106 slides, the sliding positioning block 107 slides synchronously. Under the rotation of the two groups of screws 105, the two groups of sliding positioning blocks 107 slide synchronously close to the two groups of reference positioning blocks. The positioning block 101 makes the two groups of sliding positioning blocks 107 approach and contact the other side of the distribution box to be tested. Through the cooperation between the two groups of reference positioning blocks 101 and the two groups of sliding positioning blocks 107, the positioning and clamping effect of the distribution box to be tested is achieved. While one group of sliding positioning blocks 107 slides, the elastic telescopic rod 108 at the top is squeezed to contract. Through the elastic cooperation between one group of reference positioning blocks 101 and the two groups of elastic telescopic rods 108 at the top of the sliding positioning block 107, the sensor 2 109 can adapt to the change of the distance between the reference positioning block 101 and the sliding positioning block 107.

[0045] Then the control module 3 controls the hydraulic cylinder 4 to start. After the hydraulic cylinder 4 is started, it pushes the test platen 5 downward, so that the test platen 5 contacts and squeezes the top surface of the distribution box to be tested, and changes the thrust of the hydraulic cylinder 4 according to the test requirements. In this process, the side strength deformation of the distribution box to be tested is recorded through multiple sets of sensors 109 to realize the strength deformation detection of the side of the distribution box to be tested.

[0046] When the strength deformation test on the side of the distribution box is completed, the hydraulic cylinder 4 drives the test platen 5 to slide and reset, so that the bottom end of the test platen 5 is out of contact with the top of the distribution box to be tested. The operator first rotates the rotating disk 1113 to make the rotating disk 1113 drive the rotating rod 118 to rotate synchronously. When the rotating rod 118 rotates, it drives the mounting ring 119 arranged in the surface array to rotate synchronously, so that the two groups of punching heads 1110 arranged horizontally on both sides of the mounting ring 119 are converted from a horizontal state to a vertical state. When the rotating rod 118 rotates, it drives the ratchet 1111 to rotate synchronously. When the ratchet 1111 rotates, it pushes open the pawl 1112. After the rotating rod 118 and the ratchet 1111 stop rotating, the ratchet 1111 is limited by the pawl 1112.

[0047] The operator then rotates the turntable 114, and the turntable 114 drives the screw rod 115 to rotate synchronously. The screw rod 115 rotates on the inner wall of the positioning ring 1150 and rotates downward along the direction of the positioning ring 1150. The screw rod 115 is pressed downward and drives the installation frame 111 to slide downward through the collar 113. The installation frame 111 slides and squeezes the multiple sets of elastic telescopic rods 112 to contract, so that the bottom end of the installation frame 111 approaches and contacts the top of the rotating base 91. The installation frame 111 approaches the top of the rotating base 91 and brings The movable mounting groove 116 and the mounting plate 117 in the mounting groove 116 slide downward synchronously to approach the rotating base 91. The mounting plate 117 slides along with the mounting frame 111, while driving the rotating rod 118, the mounting ring 119, and the punch head 1110 to slide downward synchronously. At this time, the two groups of punch heads 1110 on both sides of the mounting ring 119 are in a vertical state. Under the sliding action of the mounting frame 111, one group of the punch heads 1110 approaches and passes through the opening at the bottom end of the rotating base 91, and extends out from the opening at the bottom end of the rotating base 91.

[0048] Subsequently, the control module 3 controls the hydraulic cylinder 4 to start. After the hydraulic cylinder 4 is started, it pushes the test platen 5 downward. When the test platen 5 is pressed downward, it drives the installation frame 111 to slide downward synchronously. When the installation frame 111 slides, the clamping effect between the installation groove 116 and the installation plate 117 drives the installation plate 117 and the rotating rod 118 to slide downward synchronously. When the rotating rod 118 slides, it drives the installation ring 119 and the punch head 1110 to approach and contact the door of the distribution box to be tested. The punch head 1110 is pushed by the hydraulic cylinder 4 to punch the door position of the distribution box to simulate the strength deformation of the distribution box door when objects of different shapes hit the door position of the distribution box. At the same time, the strength deformation data of the door of the distribution box is detected by the sensor 150 at the bottom of the test platen 5.

[0049] When the strength deformation detection of the door part of the distribution box is completed, the control module 3 controls the motor 8 to start. After the motor 8 is started, it drives the rotating base 91 to rotate 180 degrees. While the rotating base 91 rotates, the reference positioning block 101 and the sliding positioning block 107 clamp the distribution box, and synchronously drive the distribution box to rotate 180 degrees, so that the back of the distribution box changes from a downward state to an upward state.

[0050] Similarly, the control module 3 controls the hydraulic cylinder 4 to start again and pushes the test platen 5 downward, and the hydraulic cylinder 4 pushes the punch head 1110 to punch the back of the distribution box to simulate the strength deformation of the back of the distribution box when objects of different shapes hit the back of the distribution box. At the same time, the sensor 50 at the bottom of the test platen 5 is used to detect the strength deformation data of the back of the distribution box.

[0051] At the same time, when the punch head 1110 is used to impact the back and door position of the distribution box, the operator can use the tool to unscrew the bolts to release the fixing state between the mounting groove 116 and the mounting plate 117. Then the operator can pull the mounting plate 117 out of the mounting groove 116 and disengage one end of the rotating rod 118 from the inner wall of the mounting frame 111, and replace the punch heads 1110 on both sides of the mounting ring 119 according to the strength deformation test requirements.

[0052] When the strength deformation test on the back of the distribution box is completed, the two groups of sliding bases 7 continue to slide along the directions of the two groups of electric slide rails 6. The two groups of sliding bases 7 drive the rotating base 91 to slide synchronously while sliding, so that the rotating base 91 is close to the top of the collection box 20. The rotating base 91 slides while driving the one-way gear 2 94 on the other side to approach and engage with the other group of racks 95. Under the action of the other group of racks 95, the one-way gear 2 94 produces a reverse rotation effect. The one-way gear 2 94 rotates in the reverse direction while driving the rotating rod 1 102 to rotate in the reverse direction.

[0053] When the rotating rod 102 rotates in the opposite direction, it drives the two groups of bevel gears 103 on the surface to rotate in the opposite direction synchronously. When the bevel gear 103 rotates in the opposite direction, it engages with the bevel gear 2 104 to rotate. When the bevel gear 2 104 rotates in the opposite direction, it drives the screw 105 at one end to rotate in the opposite direction synchronously. Under the action of the reverse rotation of the screw 105, the sliding sleeve 106 threadedly sleeved on the outer surface of the screw 105 slides in the opposite direction along the direction of the screw 105. When the sliding sleeve 106 slides, it drives the sliding positioning block 107 to slide in the opposite direction synchronously. Under the rotation action of the two groups of screws 105, the two groups of sliding positioning blocks 107 slide synchronously away from the two groups of reference positioning blocks 101, so that the two groups of sliding positioning blocks 107 are out of contact with the other side of the distribution box. At this time, the distribution box falls into the collection box 20 under the action of its own weight and gravity, so that the distribution box after the inspection is collected.

[0054] Subsequently, the control module 3 controls the motor 8 to start. After the motor 8 is started, it drives the rotating base 91 to rotate 180 degrees in the opposite direction to reset. At the same time, the two groups of sliding bases 7 slide in opposite directions along the two groups of electric slide rails 6. When the sliding base 7 slides, it drives the rotating base 91 and the positioning groove 92 to approach the sealed door 2, making it convenient for the operator to continue to put in the next group of distribution boxes to be tested.
