Specifically, the third pressing assembly 33 includes a second bracket 332 arranged vertically, a fifth driving element 331 is arranged on the second bracket 332, the fifth driving element 331 adopts a hydraulic cylinder or a linear electric push rod, a body of the fifth driving element 331 is fixed on the second bracket 332, and an output shaft of the fifth driving element 331 faces vertically downward; a third lower pressing rod 334 which is vertically arranged is fixed on an output shaft of the fifth driving piece 331, the lower pressing block 32 is fixed at the bottom of the third lower pressing rod 334, a second guide cylinder 333 is fixed on one side of the second support 332, and the third lower pressing rod 334 penetrates through the second guide cylinder 333 and is in sliding connection with the second guide cylinder 333; after the framework 1 is placed on the framework table 31, the fifth driving member 331 drives the third depression bar 334 to slide downwards in the second guiding cylinder 333, and the third depression bar 334 further drives the lower pressing block 32 to move downwards until the lower pressing block 32 presses the framework 1 on the framework table 31.

In order to facilitate replacement and placement of the framework table 31, the material changing driving assembly 9 capable of driving the framework table 31 to approach or depart from the second bracket 332 in the horizontal direction is arranged on one side of the positioning mechanism 3; when the framework 1 needs to be replaced, the material replacement driving assembly 9 drives the framework table 31 to be away from the second support 332 until the framework table 31 is completely withdrawn from the lower portion of the lower pressing block 32, so as to provide a larger space above the framework table 31 for replacing the framework 1.

The refueling driving assembly 9 comprises a third bracket 91 which is vertically arranged, two guide rails 92 facing the second bracket 332 are fixed on the third bracket 91, and the two guide rails 92 are parallel to each other; a sliding block 93 is connected to each of the two guide rails 92 in a sliding manner, a moving flat plate 94 is fixed to each of the two sliding blocks 93, and the framework table 31 is fixed to the moving flat plate 94; the third bracket 91 is further provided with a sixth driving element 95 for driving the sliding block 93 to move on the guide rail 92, the sixth driving element 95 adopts a hydraulic cylinder or a linear electric push rod, the body of the sixth driving element 95 is fixed on the third bracket 91 and is horizontally arranged, and the output shaft of the sixth driving element 95 is fixedly connected with the movable flat plate 94.

In order to prevent the frame block 31 from moving laterally due to stress during the process of inserting the terminal 21 into the slot 101, which may result in a decrease in the insertion accuracy, a limit fork 10 is fixed on the second bracket 332, an opening of the limit fork 10 faces the refueling driving assembly 9, and a distance between two insertion rods of the limit fork 10 is equal to a width of the frame block 31; when the framework table 31 moves to the position right below the lower pressing block 32, the framework table 31 is limited between the two insertion rods of the limiting fork 10, so that the stability of the position of the framework 1 in the insertion process of the terminal 21 is improved, and the insertion precision is improved.

The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
