Detailed Implementation

[0020] The present invention will be further described below with reference to the embodiments.

[0021] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0022] Please see Figures 1 to 4 This utility model provides a high-precision insertion and removal durability testing device, including a test chamber 1. A workbench 2 is fixedly connected inside the test chamber 1. A base plate 3, arranged vertically in parallel, is fixedly connected to the top of the workbench 2. A precision guide rod 4 is fixedly connected between the base plates 3. The precision guide rod 4 provides a stable base for the sliding of a push plate 5. A push plate 5, arranged vertically in parallel, is fitted onto the side surface of the precision guide rod 4 via a sliding assembly. On one side of the push plate 5, a female plug socket 6 is fixedly installed at the bottom of the upper push plate 5 by bolts. A female plug 7 is threadedly connected to the internal part of the female plug socket 6. The threaded connection between the female plug 7 and the female plug socket 6 allows for easy disassembly and replacement of the female plug 7 by the staff. A support plate 8 is fixedly connected to the top of the lower push plate 5, and a male plug socket 9 is fixedly connected to the top of the support plate 8. The male plug 10 is fixedly installed inside the male plug socket 9 by bolts, which facilitates easy disassembly and replacement of the male plug 10 by the staff. A drive unit 11 is installed on the outside of the base plate 3. The drive unit 11 is used to drive the push plate 5 to move up and down, thereby realizing the insertion and removal durability test of the male plug 10 and the female plug 7.

[0023] When the drive unit 11 on the outer side of the base plate 3 is activated, it drives the upper and lower push plates 5 to move up and down along the precision guide rod 4 in opposite directions, thereby driving the male plug 10 and the female plug 7 to complete the insertion or separation action, realizing the insertion and removal durability test. In this utility model, the setting of the precision guide rod 4 ensures that the sliding direction of the push plate 5 is accurate and prevents the push plate 5 from deviating and causing plug alignment deviation. The threaded connection between the female plug 7 and the female plug socket 6 and the bolt fixing method between the male plug 10 and the male plug socket 9 are convenient for the staff to disassemble and replace the female plug 7 and the male plug 10 at any time, adapting to the testing needs of different plug models and improving the versatility of the equipment. The drive unit 11 drives the push plate 5 to automatically complete the insertion and removal action, replacing manual operation, which not only improves the testing efficiency, but also avoids the error of manual operation and ensures the consistency of test results.

[0024] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the drive unit 11 includes a servo cylinder 1101 fixedly connected to the top of the upper base plate 3 and a servo cylinder 2 1102 fixedly connected to the bottom of the lower base plate 3. Both the servo cylinder 2 1102 and the servo cylinder 1101 are electrically connected to an external PLC controller. The telescopic end of the servo cylinder 1101 passes through the upper base plate 3 and is fixedly connected to the upper push plate 5 through the cylinder connecting seat 1103. The telescopic end of the servo cylinder 2 1102 passes through the lower base plate 3 and is fixedly connected to the lower push plate 5 through the pressure sensor 1104. The pressure sensor 1104 can monitor the force of inserting and removing the male plug 10 and the female plug 7 by the movement of the upper and lower push plates 5.

[0025] In this invention, servo cylinder one 1101 and servo cylinder two 1102 are controlled by PLC, possessing high-precision telescopic displacement control capabilities. This ensures accurate movement of the push plate 5, stabilizes the insertion and removal strokes of the male plug 10 and female plug 7, and improves testing accuracy. The cylinder connector 1103 enhances the connection between servo cylinder one 1101 and the upper push plate 5, preventing loosening due to long-term telescopic movement. The pressure sensor 1104 can collect insertion and removal force data in real time, facilitating the analysis of force value changes during durability testing and timely judgment of whether the plug has experienced wear, jamming, or other problems, providing data support for the test results.

[0026] Specifically, such as Figure 3 and Figure 4As shown, the sliding assembly includes guide sleeves 501 fixedly connected to the four corners of the push plate 5. The guide sleeves 501 have guide holes 502 that are adapted to the precision guide rod 4. The push plate 5 is slidably connected to the precision guide rod 4 through the guide holes 502 inside the guide sleeves 501. Several balls 503 are rotatably connected in a circular array inside the guide holes 502. The balls 503 are tangent to the side surface of the precision guide rod 4, reducing the contact with the surface of the precision guide rod 4, thereby increasing lubrication. In addition, the balls 503 are made of high carbon steel, which improves the service life of the sliding assembly.

[0027] When the drive unit 11 moves the push plate 5, the guide sleeve 501 slides along the precision guide rod 4, and the ball 503 rotates synchronously with the sliding action in the guide hole 502, converting the sliding friction between the guide sleeve 501 and the precision guide rod 4 into the rolling friction of the ball 503. In this invention, the cooperation between the guide sleeve 501 and the guide hole 502 limits the sliding direction of the push plate 5, ensuring that the push plate 5 always moves in a directional manner along the precision guide rod 4, avoiding tilting or offset of the push plate 5, and ensuring the alignment accuracy of the male plug 10 and the female plug 7. The setting of the ball 503 greatly reduces the contact area between the guide sleeve 501 and the precision guide rod 4, reduces the sliding friction resistance, increases the lubrication of the sliding process, and reduces component wear. The ball 503 is made of high carbon steel, which has excellent hardness and wear resistance, effectively improving the service life of the sliding component and reducing the maintenance frequency and cost of the equipment.

[0028] Specifically, such as Figure 3 and Figure 4 As shown, the male plug 10 and the female plug 7 are compatible and are on the same vertical line, ensuring that the male plug 10 and the female plug 7 can be stably connected together. The precision guide rods 4 are distributed in a rectangular array between the base plates 3, and the spacing between adjacent precision guide rods 4 is equal.

[0029] In this invention, the male plug 10 and the female plug 7 are aligned on the same vertical line, which structurally ensures the alignment accuracy when they are plugged in, avoiding damage to the plug or insecure connection due to misalignment, ensuring stable and reliable plugging and unplugging operations, and reducing invalid operations during testing. The rectangular array of precision guide rods 4 is evenly distributed, so that the push plate 5 is subjected to balanced force during sliding, avoiding deformation of the push plate 5 due to excessive local force, further improving the sliding stability of the push plate 5, while enhancing the load-bearing capacity of the overall structure of the equipment and extending the service life of the equipment.

[0030] Working principle and usage process of this utility model:

[0031] When staff conduct testing, they first use the threaded connection structure between the female plug 7 and the female plug socket 6, and the bolt fixing structure between the male plug 10 and the male plug socket 9, to disassemble and replace the appropriate female plug 7 and male plug 10 according to the plug model to be tested. The operation is convenient and highly compatible.

[0032] Subsequently, the staff activated the external PLC controller to control the operation of the drive unit 11 inside the test chamber 1 and outside the upper and lower parallel base plates 3 supported by the workbench 2. Servo cylinder one 1101 drives the upper push plate 5 through the cylinder connector 1103, and servo cylinder two 1102 drives the lower push plate 5 through the pressure sensor 1104. This causes the upper and lower push plates 5 to move towards or away from each other along the precision guide rods 4 distributed in a rectangular array between the base plates 3. During this process, the guide sleeves 501 at the four corners of the push plate 5 cooperate with the precision guide rods 4 through the internal guide holes 502. The high carbon steel balls 503 in the circumferential array inside the guide holes 502 roll tangentially with the precision guide rods 4, greatly reducing sliding friction to ensure smooth movement of the push plate 5. Since the male plug 10 and the female plug 7 are compatible and on the same vertical line, the upper and lower push plates 5 drive the female plug seat 6, the support plate 8 and the upper male plug seat 9 to move synchronously, successfully completing the insertion and separation of the male plug 10 and the female plug 7, and realizing the insertion and removal durability test.

[0033] During the testing process, the pressure sensor 1104 monitors the insertion and extraction force in real time and provides feedback data, which helps staff analyze the wear or jamming of the plug. At the same time, the precision guide rod 4 ensures that the sliding direction of the push plate 5 is accurate and without deviation. The test chamber 1 and the workbench 2 provide a stable environment. The overall automatic operation replaces manual operation, which not only improves testing efficiency and ensures the consistency of results, but also reduces equipment maintenance costs due to the high wear resistance of the ball bearing 503 and other design features, ensuring long-term stable operation.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
