Description

Technical Field

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

[0002] A distribution box is an assembly of switchgear, measuring instruments, protective electrical appliances, and auxiliary equipment in a closed or semi-closed metal cabinet or panel according to electrical wiring requirements, constituting a low-voltage power distribution device. It is widely used in industrial, commercial, residential and other places to provide power distribution and protection for various electrical equipment, ensuring 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 for ensuring the normal operation of the distribution box and the safety of internal electrical components.

[0003] During the existing strength deformation detection of the distribution box, since the box door of the distribution box is more likely to be damaged by impact after installation, during the strength deformation detection of the distribution box, it is necessary to conduct strength tests on the box door and the back position of the distribution box. At the same time, after the distribution box is installed, in the actual use environment, the impact situation on the box door position of the distribution box may vary, and the shapes of the impact objects hitting the box door position of the distribution box also differ. When impact objects with different shapes hit or impact the distribution box, the degree of strength deformation generated by the distribution box after being hit and impacted is different. Most of the existing detection methods are single pressing detection, resulting in the detection results being only referenceable under certain circumstances. At the same time, the detection of side deformation during the test is lacking, which is not convenient for carrying out targeted reinforcement design on the distribution box according to the data after the test. Therefore, the present application provides a distribution box strength deformation detection device and a using method to meet the requirements. Summary of the Invention

[0019] S4. The control module controls the motor to start, and the motor drives the rotating base to rotate 180 degrees. Through the rotation effect of the rotating base and the switching effect of the switching component, the stamping detection switching of two positions on the door and the back of the distribution box to be detected is realized.

[0020] Compared with the prior art, the present invention has at least the following beneficial effects:

[0021] In the above solution, by setting the triggering component, using the rotational cooperation of the rotating base and the motor, and simultaneously cooperating with the effect of the positioning component, the detection switching effect between the door and the back of the distribution box to be tested is realized. At the same time, by setting the meshing effect between the first one-way gear, the second one-way gear and the two groups of racks, and cooperating with the rotation effect of the rotating base, the switching of the rotation state of the first rotating rod is realized, so as to trigger and release the clamping effect of the positioning component. The mechanism is simple and easy to maintain. At the same time, cooperating with the effect of the switching component, the detection switching of two positions on the door and the back of the distribution box is realized. When detecting the strength of the distribution box, the test effect during the strength deformation detection of the distribution box is improved, and the detection efficiency is improved.

[0022] By setting the positioning component, using the rotation effects of the first rotating rod, the first bevel gear and the second bevel gear, and simultaneously cooperating with the sliding cooperation of the first screw rod and the sliding sleeve, the adjustment and change of the distance between the reference positioning block and the sliding positioning block are realized. Through the cooperation between the reference positioning block and the sliding positioning block, the clamping and limiting effect on the distribution box to be tested is realized around the box body of the distribution box to be tested. At the same time, two groups of first elastic telescopic rods installed at the tops of two adjacent reference positioning blocks and sliding positioning blocks, when the reference positioning block and the sliding positioning block change the distance to clamp the box body of the distribution box, through the elastic cooperation of the first elastic telescopic rods, the sensor two between the two groups of first elastic telescopic rods can be adaptively adjusted when the distance between the reference positioning block and the sliding positioning block changes, and the strength deformation of the side position of the distribution box to be tested is detected by multiple groups of sensor two. While ensuring the clamping effect of the reference positioning block and the sliding positioning block on the distribution box to be tested, the detection accuracy of the strength deformation of the side of the distribution box by multiple groups of sensor two is ensured. Detecting the side deformation is beneficial for subsequent production of the distribution box, facilitating the reinforcement design for the weak parts with large side deformation of the distribution box, and improving the integrity of the detection results.

[0023] By setting up a switching component, and making use of the mounting frame and the second elastic telescopic rod, while cooperating with the rotational fit between the second screw rod and the positioning ring, the distance between the mounting frame and the test pressing plate is changed. Meanwhile, by specially designing a mounting groove and a mounting plate on one side of the mounting frame, multiple punching heads are extended from the bottom end of the test pressing plate through the change of the distance between the mounting frame and the test pressing plate. The impact condition at the position of the distribution box door is simulated by the punching heads. Meanwhile, when testing the position of the distribution box door, the mounting plate together with the second rotating rod can be removed from the mounting frame, and punching heads with different sizes and shapes can be replaced according to different simulation requirements, so as to improve the flexibility in the strength and deformation detection of the distribution box door and the back position, and improve the diversity of the detection results.

[0044] As Figures 1 to 11 shown, an embodiment of the present invention provides a distribution box strength deformation detection device, including a device box body 1, a sealing door 2 is mounted on the surface of the device box body 1, a collection box 20 is nested and installed at the bottom of the inner wall of the device box body 1, a control module 3 is mounted on one side of the surface of the device box body 1, a hydraulic cylinder 4 is mounted at the top of the inner wall of the device box body 1, a test pressing plate 5 is connected to the bottom end of the hydraulic cylinder 4, a sensor one 50 is nested and installed at the bottom end of the test pressing plate 5, an electric slide rail 6 is mounted at the bottom of the inner wall of the device box body 1, the number of the electric slide rails 6 is set to two groups, two groups of sliding bases 7 are sleeved on the top ends of the two groups of electric slide rails 6, a motor 8 is mounted on the top end of one group of sliding bases 7, a trigger assembly 9, a trigger assembly 9 is mounted between the two groups of sliding bases 7, the trigger assembly 9 is used to trigger the loading and unloading operation of the distribution box to be tested, a positioning assembly 10, a positioning assembly 10 is mounted on the top end 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, a switching assembly 11 is mounted on the top end of the test pressing 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 end of the trigger assembly 9, and the switching assembly 11 is located above the trigger assembly 9 and the positioning assembly 10.

[0045] By setting the triggering component 9 and cooperating with the positioning component 10, the detection switching effect between the door and the back of the distribution box to be tested is realized. By setting the positioning component 10, clamping is performed around the distribution box body to be tested, and the clamping and limiting effect on the distribution box to be tested is realized. By setting the switching component 11, the impact situation at the position of the distribution box door is simulated by the stamping head 1110, and the stamping head 1110 with different sizes and shapes can be replaced, which improves the flexibility when detecting the strength deformation at the positions of the distribution box door and the back.

[0046] Such as Figures 5 to 6 As shown, the triggering component 9 includes a rotating base 91. The rotating base 91 is installed between two sliding bases 7. One end of the rotating base 91 extending out of one end of one of the sliding bases 7 is connected to the motor 8. A positioning groove 92 is provided through the bottom end of the rotating base 91. A one-way gear one 93 is nested and installed on one side of the rotating base 91. One end of the part of the one-way gear one 93 extending out of the rotating base 91 is connected to one end of the rotating rod one 102. A one-way gear two 94 is installed on the other side of the rotating base 91. One end of the part of the one-way gear two 94 extending out of the rotating base 91 is connected to the other end of the rotating rod one 102. The triggering component 9 further includes two racks 95. The number of the two racks 95 is set to two. The two racks 95 are respectively installed on both sides of the inner wall of the equipment box body 1, and the two racks 95 are respectively engaged with the one-way gear one 93 and the one-way gear two 94.

[0047] The operator first places the distribution box to be detected in the positioning groove 92 at the bottom end of the rotating base 91, with the door of the distribution box to be detected facing upwards, and one side of the distribution box to be detected is in contact with the inner walls of the two reference positioning blocks 101. Subsequently, the control module 3 controls the electric slide rail 6 to start. Under the action of the electric slide rail 6, the two sliding bases 7 slide along the two electric slide rails 6. While the two sliding bases 7 slide, they drive the rotating base 91 and the distribution box to be detected placed in the positioning groove 92 to slide synchronously, so that the distribution box to be detected reaches below the test pressing plate 5;

[0048] During this process, the rotating base 91 drives the one-way gear one 93 to slide synchronously. While the one-way gear one 93 slides, it passes through one of the racks 95. Under the action of the rack 95, the one-way gear one 93 generates synchronous rotation. While the one-way gear one 93 rotates, it drives the rotating rod one 102 to rotate synchronously;

[0049] After 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 directions of the two sets of electric slide rails 6. While the two sets of sliding bases 7 are sliding, they drive the rotating base 91 to slide synchronously, bringing the rotating base 91 close to the top of the collection box 20. While the rotating base 91 is sliding, it drives the one-way gear two 94 on the other side to approach and engage with the other set of racks 95. Under the action of the other set of racks 95, the one-way gear two 94 generates a reverse rotation effect, and while the one-way gear two 94 is rotating in the reverse direction, it drives the rotating rod one 102 to rotate in the reverse direction;

[0050] Subsequently, the control module 3 controls the motor 8 to start. After the motor 8 starts, it drives the rotating base 91 to rotate 180 degrees in the reverse direction to reset. At the same time, the two sets of sliding bases 7 slide in the reverse direction along the directions of the two sets of electric slide rails 6. While the sliding base 7 is sliding, it drives the rotating base 91 and the positioning groove 92 close to the sealing door 2, facilitating the operator to continue to put in the next set of distribution boxes to be tested.

[0051] By setting the rotational cooperation of the rotating base 91 and the motor 8, and at the same time cooperating with the effect of the positioning component 10, the detection switching effect between the box door and the back of the distribution box to be tested is realized. At the same time, in cooperation with the rotation effect of the rotating base 91, the clamping effect of the positioning component 10 is triggered and released, and the mechanism is simple and easy to maintain.

[0052] Such as Figure 7 and Figure 8As shown, the positioning assembly 10 includes a reference positioning block 101. The number of the reference positioning blocks 101 is set to two groups. Both groups of the reference positioning blocks 101 are installed at the top end of the rotating base 91. A first rotating rod 102 is installed on one side of each of the two groups of the reference positioning blocks 101. Two groups of first bevel gears 103 are sleeved on the surface of the first rotating rod 102. A second bevel gear 104 is meshed with one side of each of the first bevel gears 103. The number of the second bevel gears 104 is set to two groups. Both groups of the second bevel gears 104 are installed on one side of the two groups of the reference positioning blocks 101. One end of each of the second bevel gears 104 is connected to a first screw rod 105. The number of the first screw rods 105 is set to two groups. Both groups of the first screw rods 105 are installed at the top end of the rotating base 91. A sliding sleeve 106 is threadedly sleeved on the outer surface of the first screw rod 105. A sliding positioning block 107 is installed at one end of the sliding sleeve 106. The number of the sliding positioning blocks 107 is set to two groups. Both groups of the sliding positioning blocks 107 are installed at one end of the sliding sleeve 106. Two groups of first elastic telescopic rods 108 are respectively installed at the top ends of the two groups of the reference positioning blocks 101 and the sliding positioning blocks 107. The positioning assembly 10 further includes a second sensor 109. The number of the second sensors 109 is set to multiple groups. Two of the multiple groups of the second sensors 109 are respectively installed between the two groups of the reference positioning blocks 101 and the two groups of the sliding positioning blocks 107. The other two of the multiple groups of the second sensors 109 are respectively installed between the two groups of the reference positioning blocks 101 and the two groups of the first elastic telescopic rods 108 at the top ends of the sliding positioning blocks 107.

[0053] When the first rotating rod 102 rotates, it drives the two groups of the first bevel gears 103 on its surface to rotate synchronously. When the first bevel gears 103 rotate, they mesh with the second bevel gears 104 to drive the second bevel gears 104 to rotate. When the second bevel gears 104 rotate, they drive the first screw rods 105 at one end to rotate synchronously. Under the rotation of the first screw rods 105, the sliding sleeves 106 threadedly sleeved on the outer surfaces of the first screw rods 105 slide along the directions of the first screw rods 105. When the sliding sleeves 106 slide, they drive the sliding positioning blocks 107 to slide synchronously. Under the rotation of the two groups of the first screw rods 105, the two groups of the sliding positioning blocks 107 slide synchronously and approach the two groups of the reference positioning blocks 101, so that the two groups of the 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 the reference positioning blocks 101 and the two groups of the sliding positioning blocks 107, the positioning and clamping effects on the distribution box to be tested are realized. When one of the sliding positioning blocks 107 slides, it squeezes the first elastic telescopic rod 108 at the top end to contract. Through the elastic cooperation between the two groups of the first elastic telescopic rods 108 at the top ends of one of the reference positioning blocks 101 and the sliding positioning block 107, the second sensor 109 can adapt to the change in the distance between the reference positioning block 101 and the sliding positioning block 107.

[0054] Subsequently, the control module 3 controls the hydraulic cylinder 4 to start. After the hydraulic cylinder 4 starts, it pushes the test pressing plate 5 downward, causing the test pressing plate 5 to contact and press the top surface of the distribution box to be detected, and changes the thrust of the hydraulic cylinder 4 according to the test requirements. During this process, the multi-group sensors two 109 record data on the lateral strength deformation of the distribution box to be detected, realizing the detection of the lateral strength deformation of the distribution box to be detected;

[0055] When the detection of the strength deformation of the box door part of the distribution box is completed, the control module 3 controls the motor 8 to start. After the motor 8 starts, it drives the rotating base 91 to rotate 180 degrees. While the rotating base 91 rotates, through the clamping effect of the reference positioning block 101 and the sliding positioning block 107 on the distribution box, the distribution box is synchronously driven to rotate 180 degrees, changing the back surface of the distribution box from the downward state to the upward state;

[0056] Similarly, after the control module 3 controls the hydraulic cylinder 4 to start again, it pushes the test pressing plate 5 downward, and the hydraulic cylinder 4 pushes the stamping head 1110 to stamp the back position of the distribution box to simulate the strength deformation generated at the back position of the distribution box when objects of different shapes impact the back position of the distribution box. At the same time, the sensor one 50 at the bottom of the test pressing plate 5 detects the strength deformation data of the back position of the distribution box;

[0057] While the rotating rod one 102 rotates in the reverse direction, it drives the two groups of bevel gears one 103 on the surface to rotate synchronously in the reverse direction. While the bevel gears one 103 rotate in the reverse direction, they mesh with the bevel gears two 104 to rotate. While the bevel gears two 104 rotate in the reverse direction, they drive the screw rod one 105 at one end to rotate synchronously in the reverse direction. Under the reverse rotation action of the screw rod one 105, the sliding sleeve 106 sleeved on the outer surface of the screw rod one 105 slides in the reverse direction along the screw rod one 105. While the sliding sleeve 106 slides, it drives the sliding positioning block 107 to slide synchronously in the reverse direction. Under the rotation action of the two screw rods one 105, the two sliding positioning blocks 107 slide synchronously away from the two reference positioning blocks 101, causing the two sliding positioning blocks 107 to disengage from 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 factors, thereby collecting the distribution box after the detection is completed.

[0058] By setting the rotation effects of the rotating rod one 102, the bevel gears one 103 and the bevel gears two 104, and at the same time cooperating with the sliding fit of the screw rod one 105 and the sliding sleeve 106, the clamping and limiting effect on the distribution box to be tested is realized, and the multi-group sensors two 109 detect the strength deformation of the side position of the distribution box to be tested, ensuring the detection accuracy of the multi-group sensors two 109 for the lateral strength deformation of the distribution box while ensuring the clamping effect of the reference positioning block 101 and the sliding positioning block 107 on the distribution box to be tested.

[0059] Such as Figures 9 to 11As shown in the figure, the switching component 11 includes an installation frame 111. Multiple groups of elastic telescopic rods II 112 are installed on the side surfaces of the installation frame 111. The bottom ends of the multiple groups of elastic telescopic rods II 112 are elastically installed at the top edge of the test pressing plate 5. A collar 113 is installed on one side of the installation frame 111. A turntable 114 is nested and installed on the inner wall of the collar 113. A screw rod II 115 is installed at the bottom end of the turntable 114. A positioning ring 1150 is sleeved on the surface of the screw rod II 115. The positioning ring 1150 is installed at the top edge of one side of the test pressing plate 5. An installation groove 116 is installed on one side of the installation frame 111. The number of the installation grooves 116 is set to be multiple groups. The multiple groups of installation grooves 116 are arranged in an array on one side of the installation frame 111. An installation plate 117 is installed on the inner wall of the installation groove 116 through bolts. A rotating rod II 118 is installed on one side of the installation plate 117. The other end of the rotating rod II 118 is inserted into the inner wall of the installation frame 111. An installation ring 119 is sleeved on the surface of the rotating rod II 118. The number of the installation rings 119 is set to be multiple groups. The multiple groups of installation rings 119 are arranged in an array on the surface of the rotating rod II 118. Two stamping heads 1110 horizontally arranged on both sides of the installation ring 119 are movably inserted. A ratchet wheel 1111 is sleeved on one side surface of the rotating rod II 118. One end of the ratchet wheel 1111 contacts with a pawl 1112. The pawl 1112 is installed on the other side of the installation plate 117. A rotating disk 1113 is installed at one end of the rotating rod II 118.

[0060] After the strength deformation test on the side of the distribution box is completed, the hydraulic cylinder 4 drives the test pressing plate 5 to slide back to its original position, so that the bottom end of the test pressing plate 5 is separated from the top end of the distribution box to be detected. The operator first rotates the rotating disk 1113, so that the rotating disk 1113 drives the rotating rod II 118 to rotate synchronously. While the rotating rod II 118 rotates, it drives the installation rings 119 arranged in an array on its surface to rotate synchronously, so that the two horizontally arranged stamping heads 1110 on both sides of the installation ring 119 are converted from the horizontal state to the vertical state. While the rotating rod II 118 rotates, it drives the ratchet wheel 1111 to rotate synchronously. While the ratchet wheel 1111 rotates, it pushes open the pawl 1112, and after the rotating rod II 118 and the ratchet wheel 1111 stop rotating, the pawl 1112 limits the ratchet wheel 1111.

[0061] 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.

[0062] 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.

[0063] 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. The operator can then 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.

[0064] 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.

[0065] The present application also provides a method for using a detection device for the strength deformation of a distribution box, and the method includes the following steps:

[0066] S1. The operator first opens the sealing door 2, places the distribution box to be detected into the positioning groove 92 at the top of the rotating base 91, and the control module 3 controls the electric slide rail 6 to start, so that the rotating base 91 reaches below the test pressing plate 5. During this process, through the cooperation of the triggering component 9 and the positioning component 10, the distribution box to be detected is positioned and clamped;

[0067] S2. The control module 3 controls the hydraulic cylinder 4 to start, and presses and tests the top of the distribution box to be detected through the test pressing plate 5, and records the strength deformation data of the side position of the distribution box to be detected through multiple groups of sensors two 109 in the positioning component 10;

[0068] S3. The operator changes the distance between the mounting frame 111 and the test pressing plate 5 through the switching component 11, and simultaneously switches the horizontal states of the punching heads 1110 on both sides of the mounting ring 119, so that the punching heads 1110 extend out from the bottom end of the test pressing plate 5;

[0069] 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 punching detection switching of two positions of the box door and the back of the distribution box to be detected is realized.

[0070] The working principle of the technical solution provided by the present invention is as follows:

[0071] The operator first places the distribution box to be detected into the positioning groove 92 at the bottom of the rotating base 91, places the box door of the distribution box to be detected facing upward, and one side of the distribution box to be detected is in contact with the inner walls of the two groups of reference positioning blocks 101. Subsequently, the control module 3 controls the electric slide rail 6 to start. Under the action of the electric slide rail 6, the two groups of sliding bases 7 slide along the two groups of electric slide rails 6. While the two groups of sliding bases 7 slide, they drive the rotating base 91 and the distribution box placed in the positioning groove 92 to slide synchronously, so that the distribution box to be detected reaches below the test pressing plate 5.

[0072] During this process, the rotating base 91 drives the one-way gear one 93 to slide synchronously. While the one-way gear one 93 slides, it passes through one of the racks 95. Under the action of the rack 95, the one-way gear one 93 generates synchronous rotation. While the one-way gear one 93 rotates, it drives the rotating rod one 102 to rotate synchronously.

[0073] While the first rotating rod 102 rotates, it drives the two sets of first bevel gears 103 on its surface to rotate synchronously. While the first bevel gears 103 rotate, they mesh with the second bevel gears 104 to rotate. While the second bevel gears 104 rotate, they drive the first screw rod 105 at one end to rotate synchronously. Under the rotation of the first screw rod 105, the sliding sleeve 106 sleeved on the outer surface of the first screw rod 105 slides along the direction of the first screw rod 105. While the sliding sleeve 106 slides, it drives the sliding positioning block 107 to slide synchronously. Under the rotation of the two first screw rods 105, the two sliding positioning blocks 107 slide synchronously and approach the two reference positioning blocks 101, so that the two sliding positioning blocks 107 approach and contact the other side of the distribution box to be tested. Through the cooperation between the two reference positioning blocks 101 and the two sliding positioning blocks 107, the positioning and clamping effects on the distribution box to be tested are realized. While one of the sliding positioning blocks 107 slides, it squeezes the first elastic telescopic rod 108 at the top to contract. Through the elastic cooperation between one of the reference positioning blocks 101 and the two first elastic telescopic rods 108 at the top of the sliding positioning block 107, the sensor 2 109 can adapt to the change in the distance between the reference positioning block 101 and the sliding positioning block 107.

[0074] Subsequently, the control module 3 controls the hydraulic cylinder 4 to start. After the hydraulic cylinder 4 starts, it pushes the test pressing plate 5 downward, so that the test pressing plate 5 contacts and presses the top surface of the distribution box to be detected, and changes the thrust of the hydraulic cylinder 4 according to the test requirements. During this process, the multi-group sensors 2 109 record the data of the side strength deformation of the distribution box to be detected, realizing the detection of the side strength deformation of the distribution box to be detected.

[0075] When the test of the side strength deformation of the distribution box is completed, the hydraulic cylinder 4 drives the test pressing plate 5 to slide back to its original position, so that the bottom end of the test pressing plate 5 is separated from the top of the distribution box to be detected. The operator first rotates the turntable 1113, so that the turntable 1113 drives the second rotating rod 118 to rotate synchronously. While the second rotating rod 118 rotates, it drives the mounting rings 119 arranged in an array on its surface to rotate synchronously, so that the two stamping heads 1110 arranged horizontally on both sides of the mounting ring 119 are converted from the horizontal state to the vertical state. While the second rotating rod 118 rotates, it drives the ratchet wheel 1111 to rotate synchronously. While the ratchet wheel 1111 rotates, it pushes open the pawl 1112, and after the second rotating rod 118 and the ratchet wheel 1111 stop rotating, the pawl 1112 limits the ratchet wheel 1111.

[0076] Subsequently, the operator rotates the turntable 114. While the turntable 114 rotates, it drives the second screw 115 to rotate synchronously. The second screw 115 rotates in a threaded manner on the inner wall of the positioning ring 1150 and presses downward in a threaded manner along the direction of the positioning ring 1150. While the second screw 115 presses downward, it drives the installation frame 111 to slide downward through the collar 113. While the installation frame 111 slides, it squeezes a plurality of elastic telescopic rods two 112 to contract, so that the bottom end of the installation frame 111 approaches and contacts the top end of the rotating base 91. While the installation frame 111 approaches the top end of the rotating base 91, it drives the installation groove 116 and the installation plate 117 in the installation groove 116 to slide downward synchronously and approach the rotating base 91. While the installation plate 117 slides following the installation frame 111, it drives the second rotating rod 118, the installation ring 119, and the punching head 1110 to slide downward synchronously. Since the two punching heads 1110 on both sides of the installation ring 119 are in a vertical state at this time, under the sliding action of the installation frame 111, one of the punching 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.

[0077] Subsequently, the control module 3 controls the hydraulic cylinder 4 to start. After the hydraulic cylinder 4 starts, it pushes the test pressing plate 5 downward. While the test pressing plate 5 presses downward, it drives the installation frame 111 to slide downward synchronously. While the installation frame 111 slides, it drives the installation plate 117 and the second rotating rod 118 to slide downward synchronously through the clamping effect between the installation groove 116 and the installation plate 117. While the second rotating rod 118 slides, it drives the installation ring 119 and the punching head 1110 to approach and contact the door of the distribution box to be detected. The punching head 1110 is pushed by the hydraulic cylinder 4 to punch the position of the door of the distribution box, so as to simulate the strength deformation generated by the door of the distribution box when objects of different shapes impact the position of the door of the distribution box. At the same time, the strength deformation data of the door of the distribution box is detected by the first sensor 50 at the bottom end of the test pressing plate 5.

[0078] 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 starts, it drives the rotating base 91 to rotate 180 degrees. While the rotating base 91 rotates, it synchronously drives the distribution box to rotate 180 degrees through the clamping effect of the reference positioning block 101 and the sliding positioning block 107, so that the back of the distribution box changes from the downward state to the upward state.

[0079] Similarly, the control module 3 controls the hydraulic cylinder 4 to start again and pushes the test pressing plate 5 downward. The punching head 1110 is pushed by the hydraulic cylinder 4 to punch the back position of the distribution box, so as to simulate the strength deformation generated by the back position of the distribution box when objects of different shapes impact the back position of the distribution box. At the same time, the strength deformation data of the back position of the distribution box is detected by the first sensor 50 at the bottom end of the test pressing plate 5.

[0080] Meanwhile, when the back and the door of the distribution box are impacted by the stamping head 1110, the operator can use a tool to loosen the bolts, so that the fixing state between the installation groove 116 and the installation plate 117 is released. Subsequently, the operator can pull out the installation plate 117 from the installation groove 116, and make one end of the second rotating rod 118 disengage from the inner wall of the installation frame 111, and replace the stamping heads 1110 on both sides of the installation ring 119 according to the needs of strength deformation testing.

[0081] When the strength deformation test on the back of the distribution box is completed, the two sliding bases 7 continue to slide along the two electric slide rails 6. While the two sliding bases 7 are sliding, they drive the rotating base 91 to slide synchronously, so that the rotating base 91 approaches the top of the collection box 20. While the rotating base 91 is sliding, it drives the one-way gear two 94 on the other side to approach and engage with the other set of racks 95. Under the action of the other set of racks 95, the one-way gear two 94 produces a reverse rotation effect. While the one-way gear two 94 is rotating in the reverse direction, it drives the first rotating rod 102 to rotate in the reverse direction.

[0082] While the first rotating rod 102 is rotating in the reverse direction, it drives the two first bevel gears 103 on its surface to rotate synchronously in the reverse direction. While the first bevel gears 103 are rotating in the reverse direction, they engage with the second bevel gears 104 to rotate. While the second bevel gears 104 are rotating in the reverse direction, they drive the first screw rod 105 at one end to rotate synchronously in the reverse direction. Under the reverse rotation action of the first screw rod 105, the sliding sleeve 106 sleeved on the outer surface of the first screw rod 105 slides in the reverse direction along the first screw rod 105. While the sliding sleeve 106 is sliding, it drives the sliding positioning block 107 to slide synchronously in the reverse direction. Under the rotation action of the two first screw rods 105, the two sliding positioning blocks 107 slide synchronously away from the two reference positioning blocks 101, so that the two sliding positioning blocks 107 are disengaged from 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 factors, so as to collect the distribution box after the detection is completed.

[0083] Subsequently, the control module 3 controls the motor 8 to start. After the motor 8 starts, it drives the rotating base 91 to rotate 180 degrees in the reverse direction to reset. At the same time, the two sliding bases 7 slide in the reverse direction along the two electric slide rails 6. While the sliding bases 7 are sliding, they drive the rotating base 91 and the positioning groove 92 to approach the sealing door 2, which is convenient for the operator to continue to put the next set of distribution boxes to be tested.
