In order to ensure the energy supply of electric vehicles, charging piles are usually installed to supply energy to electric vehicles. The charging gun head is connected to the electric vehicle so that the electric energy can be smoothly input into the battery of the electric vehicle and stored.

[0003] In most production and assembly equipment for charging gun heads, the DC socket, contact terminals and DC inner cover are usually assembled and then transported to the assembly equipment, and the DC socket is assembled and pressed onto the AC shell. Finally, the DC socket and the AC shell are fixed with screws. However, during the assembly of the DC socket and the AC shell, it is impossible to continuously press and control the DC socket and the AC shell. When the screws are turned to fix the AC shell and the DC socket, the AC shell and the DC socket are prone to loosening, and it is impossible to ensure that the DC socket and the AC shell are tightly fitted, which is not convenient for subsequent fixing with screws. Summary of the invention

[0004] In order to improve the convenience of an assembly device for a charging gun head and a production method thereof during operation, the present application provides an assembly device for a charging gun head and a production method thereof.

A first rotating handle 359 is arranged at one end of the sleeve 357 away from the loading block 354. A sliding groove 3581 is opened on the side wall of the sleeve 357. In this embodiment, the sliding groove 3581 includes a curved groove and a straight groove. The curved groove starts from a position near the bottom and ends at the top on the side wall of the sleeve 357. The straight groove connects the starting position and the ending position of the curved groove on the sleeve 357 to ensure that the sleeve 357 can return to its original position quickly. A first locking groove 3582 is opened at the starting position of the curved groove, and a second locking groove 3583 is opened at the ending position of the curved groove. The groove depth of the first locking groove 3582 and the second locking groove 3583 is deeper than the groove depth of the sliding groove 3581.

[0053] Control the first turning handle 359 to rotate the sleeve 357 and press the sleeve 357 downward, and the sleeve 357 slides downward on the first slide bar 353. When the sleeve 357 slides downward on the first slide bar 353, the first slide bar 353 enters the sleeve 357. At this time, the sleeve 357 pushes the loading block 354 to compress the spring 356 and move downward at the same time. Release the spring 356, and the loading block 354 is pushed upward by the elastic force of the spring 356 to complete the upper and lower height adjustment and return process.

[0054] Reference Figure 5 , Figure 6 and Figure 7The loading plate 351 is provided with a locking assembly 36, which includes a mounting block 361, which is fixedly mounted on the loading plate 351, and a locking rod 362 is slidably mounted on the mounting block 361, and the locking rod 362 is arranged through the mounting block 361, and the end of the locking rod 362 close to the sleeve 357 is slidably connected to the sleeve 357 through the sliding groove 3581, and the end of the locking rod 362 away from the sleeve 357 is provided with a second handle 363, and the mounting block 361 is provided with a first fixed groove 3641, and the first fixed groove 3641 is provided with a second handle 363. The length direction of the slot length is parallel to the length direction of the locking rod 362. A second fixing slot 3642 is provided on the mounting block 361 near the sleeve 357. The second fixing slot 3642 is perpendicular to and communicates with the first fixing slot 3641. A third fixing slot 3643 is provided on the mounting block 361. The third fixing slot 3643 is arranged away from the sleeve 357 relative to the second fixing slot 3642. The third fixing slot 3643 is perpendicular to and communicates with the first fixing slot 3641. A fixing rod 365 is installed on the first locking rod 362. The fixing rod 365 is slidably connected to the mounting block 361 through the first fixing slot 3641, the second fixing slot 3642 and the third fixing slot 3643.

[0055] When the locking rod 362 moves to the first locking groove 3582 or the second locking groove 3583, pushing the second turning handle 363 can quickly push the locking rod 362 into the first locking groove 3582 or the second locking groove 3583, fix and lock the sleeve 357 to prevent the sleeve 357 from continuing to move, and rotate the second turning handle 363 to rotate the fixing rod 365 into the second fixing groove 3642, which can limit the locking rod 362 in the horizontal direction and prevent the locking rod 362 from falling out of the first locking groove 3582 or the second locking groove 3583, thereby enhancing the stability during locking. When the height of the loading block 354 needs to be adjusted, the fixing rod 365 is rotated out of the second fixing groove 3642 to the first fixing groove 3641, and at the same time, the fixing rod 365 is rotated into the third fixing groove 3643 to prevent the locking rod 362 and the sleeve 357 from sliding in the sliding groove 3581. The locking rod 362 and the sleeve 357 are pressed tightly against each other to increase the friction and block the movement of the sleeve 357.

[0056] Reference Figure 5The loading block 354 is provided with a clamping assembly 37 for mounting the DC socket 11. The clamping assembly 37 includes a rotating cylinder 371. The rotating cylinder 371 is fixedly mounted on a vertical side wall on one side of the loading block 354. A rotating disk 372 is fixedly mounted on the output shaft of the rotating cylinder 371. A mounting frame 373 is fixedly mounted on the rotating disk 372. A threaded rod 374 is threadedly connected to the mounting frame 373 away from the rotating disk 372. A third rotating handle 3741 is provided at one end of the threaded rod 374 away from the mounting frame 373. The threaded rod 374 is rotatably connected to one end of the turntable 372, and a guide groove 3743 is opened on the mounting frame 373. The slide plate 3742 is slidingly connected to the mounting frame 373 through the guide groove 3743. A first clamping plate 375 is fixedly installed on the slide plate 3742, and a second clamping plate 376 is fixedly installed on the mounting frame 373 to cooperate with the first clamping plate 375. In this embodiment, the shapes of the first clamping plate 375 and the second clamping plate 376 are matched with the shape of the DC socket 11.

[0057] Reference Figure 3 and Figure 5 , the second mounting hole 111 of the DC socket 11 is placed upward on the first clamping plate 375 and the second clamping plate 376, and the third rotating handle 3741 is manipulated to rotate the threaded rod 374, so that the first clamping plate 375 moves toward the second clamping plate 376 and clamps the DC socket 11. After the DC socket 11 is clamped, the second contact terminal 13 is installed on the DC socket 11, and then the end cover 16 is installed on the DC socket 11 so that the end cover 16 clamps and fixes the second contact terminal 13, and then the DC inner cover 12 is installed on the end cover 16. In this embodiment, the end cover 16 inner cover is clamped and fixed with the DC socket 11, and the DC inner cover 12 can also be clamped on the end cover 16. When the DC socket 11 is assembled, the rotating cylinder 371 controls the rotating disk 372 to rotate 180 degrees, so that the second mounting hole 111 of the DC socket 11 faces downward, and then the servo motor 33 controls the screw rod 32 to rotate, thereby driving the DC socket 11 to move above the positioning block 43 so that the DC socket 11 reaches the assembly position with the AC housing 14.

[0058] Reference Figure 6 , Figure 7 and Figure 8When the DC socket 11 moves to the assembly position, the locking rod 362 is inserted into the first locking groove 3582, and the fixing rod 365 is in the third fixing groove 3643. The second turning handle 363 is controlled to rotate the locking rod 362 so that the fixing rod 365 is rotated from the third fixing groove 3643 to the first fixing groove 3641, and the locking rod 362 is dragged away from the sleeve 357 to move the fixing rod 365 from the first fixing groove 3641 to the second fixing groove 3642, so that the locking rod 362 is pulled out of the first locking groove 3582 and is in the sliding groove 3581, and then the locking rod 362 is rotated to make the fixing rod 365 rotate into the second fixing groove 3642, so as to prevent the locking rod 362 from automatically inserting into the sleeve 357 and affecting the movement of the sleeve 357. The first turning handle 359 is turned and the sleeve 357 is pressed downward to move the sleeve 357 downward. When the sleeve 357 moves downward, it will slide with the locking rod 362. The downward movement speed of the sleeve 357 is controlled by sliding with the locking rod 362 through the curved groove stage of the sliding groove 3581, so that the DC socket 11 can be smoothly assembled with the AC housing 14. The sleeve 357 drives the loading block 354 to press the spring 356 to move downward on the first sliding rod 353, so that the DC socket 11 installed on the clamping assembly 37 moves downward and is inserted into the AC housing 14.

[0059] When the sleeve 357 moves downward so that the locking rod 362 is in the second locking groove 3583 position, the DC socket 11 has been completely inserted into the AC housing 14 and the assembly with the AC housing 14 is completed. The locking rod 362 is rotated to make the fixing rod 365 move from the second fixing groove 3642 to the first fixing groove 3641, and the locking rod 362 is pushed to insert into the second locking groove 3583 of the sleeve 357 to fix the sleeve 357. The locking rod 362 is rotated to move the fixing rod 365 from the first fixing groove 3641 to the third fixing groove 3643 to prevent the locking rod 362 from being separated from the second locking groove 3583. The sleeve 357 is fixed to continuously fix the DC socket 11 and press it on the AC housing 14 to prevent the DC socket 11 and the AC housing 14 from loosening during the screwing process, so as to facilitate the rapid assembly of the DC socket 11 and the AC housing 14.

[0060] Reference Figure 5 , Figure 6 and Figure 7When the processing is completed, the third turning handle 3741 is controlled to rotate the threaded rod 374 to loosen the DC socket 11 from the first clamping plate 375 and the second clamping plate 376, the locking rod 362 is rotated and pulled to disengage the locking rod 362 from the second locking groove 3583, and the loading block 354 is moved upward by the rebound of the spring 356, and the sleeve 357 moves upward. When the locking rod 362 moves to the position of the first locking groove 3582, the locking rod 362 is rotated and pushed to be inserted into the first locking groove 3582 of the sleeve 357, and the locking rod 362 is rotated into the second locking groove 3583 to fix the sleeve 357 to prevent the sleeve 357 from sliding downward when the second contact terminal 13 and the DC inner cover 12 are assembled with the DC socket 11. After the sleeve 357 is fixed, the rotating cylinder 371 controls the turntable 372 to rotate so that the first clamping plate 375 and the second clamping plate 376 face upward, and continue to complete the next round of assembly production.
