The steps of the processing method of the charging pile spring assembly include:

[0009] Control the hydraulic source of the charging pile spring assembly equipment to drive the driving cylinder of the charging pile spring assembly equipment to move. The driving cylinder pushes one of the vehicle parts located on the clamping mechanism into one end of the spring body until both ends of the spring body are completely sleeved into the two vehicle parts respectively;

[0010] Control the electroplating equipment to electroplatingly connect the positions where both ends of the spring body are sleeved with the two vehicle parts.

[0011] In one embodiment, the steps of controlling the hydraulic source of the charging pile spring assembly equipment to drive the driving cylinder of the charging pile spring assembly equipment to move include:

[0012] Control the hydraulic source of the charging pile spring assembly equipment to adjust the pressure and speed of the driving cylinder so that the driving cylinder evenly extrudes the end of one of the vehicle parts to move away from the hydraulic source.

[0017] Control the clamping mechanism of the charging pile spring assembly equipment to clamp the spring body and the two vehicle parts.

[0018] The charging pile spring assembly of the technical solution of the present invention includes a spring body and at least two vehicle parts.

[0032] The present invention provides a charging pile spring assembly.

[0033] Please refer to Figure 1 and Figure 2, in an embodiment of the present invention, the charging pile spring assembly includes a spring body 10 and at least two vehicle parts 20. Each vehicle part 20 includes a vehicle part body 21 and a limiting boss 22 provided on the outer wall of the vehicle part body 21. The limiting boss 22 is arranged around the periphery of the vehicle part body 21; the spring body 10 is sleeved on the outer wall of the vehicle part body 21 and abuts against the limiting boss 22; the vehicle part body 21 and the limiting boss 22 are provided with a drainage groove 20a, and the drainage groove 20a extends from the outer wall of the vehicle body 21 to the outer wall of the limiting boss 22, and the drainage groove 20a is used for discharging electroplating residual liquid.

[0034] This embodiment provides a charging pile spring assembly, which includes a spring body 10 and at least two vehicle parts 20. The spring body 10 has good elasticity and corrosion resistance. The spring body 10 is in a spiral shape, and its two ends are respectively connected to two vehicle part bodies 21. Each vehicle part 20 includes a vehicle part body 21 and a limiting boss 22 provided on the outer wall of the vehicle part body 21. The vehicle part body 21 is made of metal or high-strength plastic and has good mechanical strength and wear resistance. The vehicle part body 21 is in a cylindrical shape, and its outer wall is provided with a drainage groove 20a for discharging electroplating residual liquid. The limiting boss 22 is arranged around the periphery of the vehicle part body 21, and its height is slightly higher than the outer wall of the vehicle part body 21 to limit the movement range of the spring body 10.

[0035] When the spring body 10 is matched with the vehicle part body 21, one end of the spring body 10 is inserted into the interior of the vehicle part body 21, and the other end is inserted into the interior of another vehicle part body 21. During the electroplating process of the charging pile spring assembly, the electroplating residual liquid will extend along the drainage groove 20a from the outer wall of the vehicle part body 21 to the outer wall of the limiting boss 22, avoiding the electroplating residual liquid remaining on the outer wall of the vehicle part body 21 or the outer wall of the spring body 10 and corroding the vehicle part body 21 and the spring body 10.

[0036] The vehicle part body 21 and the limiting boss 22 are provided with a drainage groove 20a, which is a major innovation point of the present invention. The drainage groove 20a extends from the outer wall of the vehicle part body 21 to the outer wall of the limiting boss 22, and this design effectively solves the problem of discharging electroplating residual liquid. During the electroplating process, if the residual liquid is not discharged in time, it will corrode the internal structure of the charging pile and affect its normal operation. The drainage groove 20a design can timely discharge the electroplating residual liquid, protect the integrity of the internal structure of the charging pile, and extend the service life of the charging pile.

[0037] In this case, by adopting a charging pile spring assembly with drainage grooves 20a provided on the vehicle part body 21 and the limit boss 22, during the processing and assembly of the charging pile spring assembly, the assembly equipment of the charging pile spring assembly can directly fit both ends of the spring body 10 completely into the two vehicle parts 20, without only fitting both ends of the spring body 10 into specific positions of the two vehicle parts 20 and then continuing to fit both ends of the spring body 10 completely into the two vehicle parts 20 after electroplating. Instead, the two vehicle parts 20 can be installed at the preset positions of the spring body 10 at one time, and no further assembly is required later, ensuring that the charging pile spring assembly will not be damaged and improving the quality of the charging pile spring assembly.

[0038] In one embodiment, please refer to Figure 1 and Figure 2 , the depth of the drainage groove 20a located on the outer wall of the vehicle body part 21 is less than the depth of the drainage groove 20a located on the outer wall of the limit boss 22.

[0039] In this embodiment, by designing the depths of the drainage grooves 20a differently, the drainage volume of the drainage groove 20a located on the outer wall of the limit boss 22 is further increased, making it easier for the electroplating residual liquid to drain away from the drainage groove 20a of the limit boss 22 and accelerating the discharge speed of the electroplating residual liquid of the charging pile spring assembly.

[0040] In one embodiment, please refer to Figure 1 and Figure 2 , a drainage groove 20a is provided from the position where the limit boss 22 is connected to the vehicle part body 21 to the edge position of the limit boss 22.

[0041] In this embodiment, by extending the drainage groove 20a from the central position of the limit boss 22 to the edge position of the limit boss 22, the electroplating residual liquid can be guided from the central position of the limit boss 22 to the edge position of the limit boss 22. In this way, the electroplating residual liquid is less likely to remain on the outer wall of the limit boss 22, improving the drainage effect of the drainage groove 20a for discharging the electroplating residual liquid.

[0042] The present invention also proposes a processing method for a charging pile spring assembly. Please refer to Figure 1 , Figure 3 and Figure 4 , the charging pile spring assembly is the above-mentioned charging pile spring assembly, and an assembly is carried out using the assembly equipment of the charging pile spring assembly; the steps of the processing method of the charging pile spring assembly include:

[0043] S10: Control the hydraulic source 100 of the assembly equipment of the charging pile spring assembly to drive the driving oil cylinder 200 of the assembly equipment of the charging pile spring assembly to move. The driving oil cylinder 200 pushes one of the vehicle parts 20 located on the clamping mechanism 300 into one end of the spring body 10 until both ends of the spring body 10 are respectively and completely sleeved into the two vehicle parts 20;

[0044] In this embodiment, the spring body 10 is the main component of the charging pile spring assembly, and its two ends are connected to the vehicle parts 20. The vehicle parts 20 are auxiliary components of the charging pile spring assembly and are used to connect to the spring body 10. The hydraulic source 100 is a common hydraulic pump station that can provide stable hydraulic power for the driving oil cylinder 200. The driving oil cylinder 200 is connected between the hydraulic source 100 and the clamping mechanism 300 and is used to drive the movement of the clamping mechanism 300. The clamping mechanism 300 is provided with a plurality of clamping claws that respectively clamp the two vehicle parts 20 and the spring body 10, and the two vehicle parts 20 are arranged at intervals before being assembled with the spring body 10. The clamping mechanism 300 abuts against the driving oil cylinder 200 through the piston rod of the driving oil cylinder 200, and the movement of the driving oil cylinder 200 causes the clamping mechanism 300 to move away from the hydraulic source 100.

[0045] First, start the hydraulic source 100 to fill the driving oil cylinder 200 with hydraulic oil. The piston is affected by the hydraulic pressure and drives the piston rod to move to the right, causing the clamping mechanism 300 to move in the same direction. Until the clamping mechanism 300 moves to a suitable position, the two ends of the spring body 10 are respectively fully sleeved into the two vehicle parts 20, and the charging pile spring assembly is assembled. After the assembly is completed, the driving oil cylinder 200 moves in the reverse direction to prepare for the next assembly.

[0046] By controlling the driving oil cylinder 200 of the assembly equipment through the hydraulic source 100, the rapid and precise docking of the vehicle parts 20 and the spring body 10 is achieved. This innovative technical feature avoids the problems of position deviation and inaccurate docking that may occur in the traditional manual assembly process, and significantly improves the assembly accuracy and consistency.

[0047] S20: Control the electroplating equipment to electroplatingly connect the positions where the two ends of the spring body 10 are sleeved with the two vehicle parts 20.

[0048] By precisely controlling the electroplating equipment, the positions where the two ends of the spring body 10 are sleeved with the two vehicle parts 20 can achieve precise electroplating connection, avoiding connection defects caused by uneven electroplating.

[0049] The electroplating equipment electroplatingly connects the positions where the two ends of the spring body 10 are sleeved with the vehicle parts 20. This step not only enhances the wear resistance and corrosion resistance of the connection part, but also improves the stability and reliability of the connection. The application of the electroplating connection technology enables the charging pile spring assembly to withstand more charge and discharge cycles during long-term use, reducing the failure rate and maintenance cost.

[0050] With the above settings, the charging pile spring component assembly device can directly insert both ends of the spring body 10 completely into the two vehicle parts 20, without only inserting both ends of the spring body 10 into specific positions of the two vehicle parts 20 and then continuing to insert both ends of the spring body 10 completely into the two vehicle parts 20 after electroplating. Instead, both ends of the spring body 10 can be directly inserted into the preset positions of the two vehicle parts 20 at one time. Here, the preset positions refer to the limiting bosses of the vehicle parts 20. The limiting bosses of the two vehicle parts 20 are in contact with both ends of the spring body, and no further assembly is required afterwards, ensuring that the charging pile spring component will not be damaged and improving the quality of the charging pile spring component.

[0051] In one embodiment, please refer to Figure 1 , Figure 3 and Figure 4 , the steps of controlling the hydraulic source 100 of the charging pile spring component assembly device to drive the driving oil cylinder 200 of the charging pile spring component assembly device to move include:

[0052] Control the hydraulic source 100 of the charging pile spring component assembly device to adjust the pressure and speed of the driving oil cylinder 200, so that the driving oil cylinder 200 evenly extrudes the end of one of the vehicle parts 20 and moves it away from the hydraulic source 100.

[0053] Set the target pressure value of the driving oil cylinder 200 through the hydraulic source 100 control system; start the hydraulic source 100 to gradually increase the pressure of the driving oil cylinder 200 to the set target pressure value; when the pressure of the driving oil cylinder 200 reaches the target pressure value, keep the pressure stable. During this process, the hydraulic source 100 control system realizes precise control of the pressure of the driving oil cylinder 200 by adjusting the flow rate and pressure of the hydraulic pump. Then, set the target speed value of the driving oil cylinder 200 through the hydraulic source 100 control system; according to the feedback signal of the displacement sensor of the driving oil cylinder 200, monitor the actual speed of the driving oil cylinder 200 in real time; when there is a deviation between the actual speed and the target speed of the driving oil cylinder 200, the hydraulic source 100 control system automatically adjusts the flow rate of the hydraulic pump to make the speed of the driving oil cylinder 200 gradually approach the target speed; when the speed of the driving oil cylinder 200 reaches the target speed, keep the speed stable.

[0054] After the pressure and speed of the driving oil cylinder 200 are adjusted, start the uniform extrusion operation of the driving oil cylinder 200. The driving oil cylinder 200 starts to extrude the end of the vehicle part 20 with the set pressure and speed; the piston rod of the driving oil cylinder 200 moves towards the vehicle part 20 until the set displacement value is reached; during this process, the displacement of the driving oil cylinder 200 is monitored in real time through the displacement sensor to ensure that the driving oil cylinder 200 evenly extrudes the end of the vehicle part 20.

[0055] In this embodiment, by controlling the driving oil cylinder 200 to extrude the end of the vehicle part 20 at a uniform speed, the two vehicle parts 20 can be slowly sleeved onto both ends of the spring body 10, so that the two vehicle parts 20 and the spring body 10 will not suddenly be subjected to a huge impact force, thereby avoiding damage and deformation of the two vehicle parts 20 and the spring body 10 and improving the quality of the charging pile spring assembly.

[0056] In one embodiment, please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 , before the step of S10: controlling the hydraulic source 100 of the charging pile spring assembly device to drive the driving oil cylinder 200 of the charging pile spring assembly device to move, and the driving oil cylinder 200 pushing one of the vehicle parts 20 located on the clamping mechanism 300 into one end of the spring body 10 until both ends of the spring body 10 are respectively completely sleeved into the two vehicle parts 20, further includes:

[0057] S30: The hydraulic source 100 receives an adjustment instruction input by the user and parses out adjustment parameters according to the adjustment instruction;

[0058] S40: Control the motor 110 and the control valve 120 of the hydraulic source 100 to perform corresponding adjustments on the driving oil cylinder 200 according to the adjustment parameters respectively.

[0059] The hydraulic source 100 is used to provide the hydraulic power required by the driving oil cylinder 200. The hydraulic source 100 is provided with a control unit for parsing the adjustment instruction input by the user and generating corresponding adjustment parameters. The motor 110 of the hydraulic source 100 is used to drive the hydraulic source 100 to work. The control valve 120 is used to adjust the hydraulic flow rate and pressure output by the hydraulic source 100. The driving oil cylinder 200 is used to perform specific driving actions.

[0060] The control unit receives the adjustment instruction input by the user, and this instruction may include but is not limited to parameters such as the extension speed, extension length, and pressure value of the driving oil cylinder 200. The control unit also parses the received adjustment instruction and parses out the corresponding adjustment parameters according to the adjustment instruction. For example, if the adjustment instruction input by the user is "the extension speed of the driving oil cylinder 200 is 5 mm / s", the control unit will parse out the adjustment parameter as "extension speed = 5 mm / s". The control unit transmits the parsed adjustment parameters to the motor 110 and the control valve 120. The motor 110 adjusts its rotation speed according to the speed parameter in the adjustment parameters to make the extension speed of the driving oil cylinder 200 match the adjustment instruction input by the user. The control valve 120 adjusts the hydraulic flow rate and pressure output by the hydraulic source 100 according to the pressure and flow rate parameters in the adjustment parameters to make the extension length and pressure value of the driving oil cylinder 200 match the adjustment instruction input by the user.

[0061] The hydraulic power source 100 can receive the adjustment instructions input by the user and accurately parse out the required adjustment parameters according to these instructions. This process greatly improves the convenience of user operation and reduces the possibility of operation errors. Compared with the prior art, the adjustment process of the present invention is more intuitive and user-friendly. Users can easily operate without professional knowledge, thus lowering the technical threshold and improving work efficiency.

[0062] The motor 110 and control valve 120 that control the hydraulic power source 100 can strictly adjust the drive cylinder 200 according to the parsed adjustment parameters. This process ensures the response speed and adjustment accuracy of the hydraulic system. Compared with the prior art, the present invention has a significant improvement in response time, can quickly meet the adjustment needs of users, and avoids system instability or production accidents caused by slow response. At the same time, the improvement of adjustment accuracy means that the movement of the drive cylinder 200 is more precise, thus improving the control performance of the hydraulic system and the product processing quality.

[0063] In an embodiment, please refer to Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 , before the step of the hydraulic power source 100 receiving the adjustment instructions input by the user and parsing out the adjustment parameters according to the adjustment instructions, it further includes:

[0064] S50: Control the clamping mechanism 300 of the charging pile spring assembly device to clamp the spring body 10 and two vehicle parts 20.

[0065] The charging pile spring assembly device further includes a control module for controlling the clamping mechanism 300 to clamp the spring body 10 and the vehicle parts 20 and a driving module for driving the clamping mechanism 300 to clamp the spring body 10 and the vehicle parts 20; the clamping mechanism 300 includes a plurality of clamping arms, and the plurality of clamping arms are arranged at intervals along the length direction of the charging pile spring assembly device, and the plurality of clamping arms respectively clamp the spring body 10 and two vehicle parts 20. The driving module includes a motor 110, a lead screw and a slider for driving the opening and closing action of the clamping arms. The control module is a PLC controller for controlling the operation of the driving module.

[0066] After the device is started, initialize the device, including detecting the position and state of the clamping arms. Each clamping arm forms an open state under the action of the driving device; at this time, the staff manually place the spring body 10 and two vehicle parts 20 on the plurality of clamping arms respectively, and then the driving device controls the plurality of clamping arms to form a clamping state to clamp the spring body 10 and two vehicle parts 20.

[0067] The design of the clamping mechanism 300 ensures precise position control of the spring body 10 and the vehicle part 20 during the assembly process, avoiding assembly errors caused by position deviations. The effective fixing function of the clamping mechanism 300 enhances the stability of the entire assembly device.

[0068] The above are only exemplary embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
