Referring to fig. 1 to 4, the processing tool 100 of the present invention is suitable for mounting the female connector housing 7 on the housing 8. In the present embodiment, the female socket 7 of the electrical connector is exemplified by a female socket of a charging interface such as Micro USB, Type C, Lightning, etc., but the invention is not limited to the above examples. The housing 8 is illustrated as a housing 8 of an electronic product such as a mobile phone, a tablet, a wearable device, etc., and has a base wall 81 and a surrounding wall 82 extending downward from the periphery of the base wall 81. The surrounding wall 82 has a mounting groove 821 formed on the opposite inner side and an electrical connection port 822 formed on the opposite outer side and communicating with the mounting groove 821.

The step 312b surrounds the platform 312a and is lower than the platform 312a, and is adapted to abut against the surrounding wall 82 of the housing 8. The first slots 312c are recessed from the left and right sides of the carrier 312 and located above the two positioning slot portions 3114. The second slot 312d is recessed from the front side of the carrier 312 and corresponds to the upper side of the guiding slot 311 e.

Referring to fig. 7, 9 and 10, the first positioning module 32 is disposed on the base 311 and has a first cylinder 321, a longitudinal pushing block 322, two transverse pushing blocks 323 and two first elastic member sets 324. The first cylinder 321 has a first link 321a connected to the bottom of the longitudinal push block 322. The vertical push block 322 is provided in the vertical groove portion 3111 and is movable in the front-rear direction D1 by being driven by the first link 321a of the first cylinder 321. The longitudinal push block 322 has side protrusions 322a on both left and right sides. Each side protrusion 322a has a triangular shape and has an inclined surface 3221 facing outward. The two lateral pushing blocks 323 are disposed in the lateral groove portion 3112 and located on the left and right sides of the longitudinal pushing block 322 to correspond to the two side protrusions 322a, respectively. Each lateral pushing block 323 has a pushed portion 323a which can be pushed by the inclined surface 3221 of the corresponding side protrusion 322a to move in a direction away from the longitudinal pushing block 322, and a positioning lever portion 323b which is connected to the pushed portion 323a and is brought into contact with the surrounding wall 82 of the housing 8. The pushed portion 323a of the lateral pushing block 323 is bent upward at the left and right ends of the lateral groove portion 3112 and extends through the positioning groove portion 3114. The positioning rod portions 323b are respectively connected to the ends of the pushed portions 323a and located on the top surface 311b of the base 311. The positioning rod portions 323b can move in the first slots 312c to abut against or separate from the surrounding wall 82 of the housing 8, respectively, and in the present embodiment, the positioning rod portions 323b extend in the front-rear direction D1 to increase the range of engagement to the left and right sides of the surrounding wall 82 of the housing 8.

Referring to fig. 7, the first elastic element sets 324 are respectively disposed in the through holes 311d, and each of the first elastic element sets 324 has a first spring 324a and a first elastic force adjusting screw 324 b. The first spring 324a is disposed in the corresponding through hole 311d, and two ends of the first spring respectively abut against the first elastic force adjusting screw 324b and the corresponding transverse pushing block 323. The first elastic force adjusting screws 324b are disposed at the outer ends of the corresponding through holes 311d for screwing in or out of the through holes 311d to adjust the compression amount of the first springs 324a, thereby adjusting the elastic force of the first springs 324 a.

Referring to fig. 1, 2, 7 and 8, when the longitudinal pushing block 322 is driven by the first cylinder 321 to move toward the second assembly unit 4 (see fig. 1), the two side protrusions 322a of the longitudinal pushing block 322 push against the two transverse pushing blocks 323, respectively, so that the transverse pushing blocks 323 move away from the longitudinal pushing block 322 to compress the first spring 324a and accumulate the elastic restoring force. The two positioning lever portions 323b are also moved in the direction away from the longitudinal push block 322, respectively, and abut from the inside to the outside against the opposite inner sides of the surrounding wall 82 of the housing 8, so that the housing 8 can be positioned together in the left-right direction D2. After the processing fixture 100 finishes processing, the first cylinder 321 drives the longitudinal pushing block 322 to return in a direction away from the second assembling unit 4, and the lateral protrusions 322a of the longitudinal pushing block 322 separate from the lateral pushing block 323, so that the two first springs 324a release the elastic return force to oppositely drive the lateral pushing block 323 to return.

The mounting carrier 333 has a guide groove 333a located at the bottom and extending in the front-rear direction D1. The guide post 334 is disposed on the linkage block 332, and has one end inserted into the base 332a and the other end passing through the guide slot 333a of the assembly carrier 333, so that the assembly carrier 333 can move in the front-back direction D1 relative to the linkage block 332 when disposed on the linkage block 332. The second elastic member set 335 has a top pillar 335a movably disposed through the mounting portion 332c and used for abutting against the mounting carrier 333, and a second spring 335b disposed on the mounting portion 332c and having two ends abutting against the mounting portion 332c and the top pillar 335a, respectively. The specific process of mounting the female electrical connector holder 7 in the mounting groove 821 of the housing 8 will be described in detail in the following paragraphs in connection with the second assembly unit 4.

Referring to fig. 14 to 16, each floating positioning module 34 has a fixed block 341, a third elastic element group 342, a positioning pin group 343, a stopping cylinder 344 and a stopper 345. The fixing block 341 is disposed on the bottom surface 311a of the base 311, and defines a mounting hole 341a extending in the vertical direction D3 and an actuating hole 341b crossing the mounting hole 341 a. In this embodiment, the fixed block 341 is divided into an upper block portion 341c and a lower block portion 341d, the mounting hole 341a is divided into an upper hole portion 3411 located in the upper block portion 341c and a lower hole portion 3412 located in the lower block portion 341d, and the actuating hole 341b is formed in the upper block portion 341c and intersects with the upper hole portion 3411.

Referring to fig. 17 and 18, the stop 34 is movable relative to the fixed block 341 between an unlocked position shown in fig. 17 and a locked position shown in fig. 18. When the stopper 345 is at the unlock position, the stopper 345 is pushed out by the stopper cylinder 344, and the portion of the stopper 345 having a smaller outer diameter corresponds to the side surface 3431 of the floating pole 343a, so that the stopper surface 345a is separated from the side surface 3431. When the stopper 345 is in the locking position, the stopper 345 is driven by the stopper cylinder 344 to retract inward, so that the part of the stopper 345 with a larger outer diameter is close to the floating post 343a and the stopper surface 345a is abutted against the side surface 3431, and the floating post 343a cannot move up and down relative to the fixed block 341, thereby achieving the braking effect.
