when the riveting mechanism works, if the positioning pin 6-3 can enter the riveting jack 1-1 when pressed downwards, when the riveting mechanism reaches the position above the riveting jack 1-1, the second driving mechanism controls the riveting block 6-5 to move downwards, so that the riveting block 6-5 presses the wiring piece 2 in the guide groove 6-4 downwards, and the wiring piece 2 is riveted into the riveting jack 1-1.
As a further scheme of the invention, the second power mechanism comprises a first cylinder 7-1, the first cylinder 7-1 is fixedly arranged at the upper end of the positioning plate 3, the output end of the first cylinder 7-1 is fixedly connected with a first connecting block 7-2, and the connecting block 7-2 is fixedly connected with the upper end of the sliding shell 6-1.

In operation, after the detection mechanism reaches the position above the preset position of the riveting jack 1-1, the second cylinder 7-3 is started to drive the sliding block 7-5 to move downwards, (as shown in fig. 2), in the process that the sliding block 7-5 moves downwards, the first guide rod 7-7 connected in the first sliding groove 7-5-1 is driven to move downwards, (as shown in fig. 6), further, the first guide rod 7-7 can press the spring 6-3-2 downwards to compress the spring 6-3-2 and form a downward elastic force on the upper end of the positioning pin 6-3, further, the positioning pin 6-3 is driven to move downwards by the elastic force of the spring 6-3-2 (in the process that the positioning pin 6-3 moves downwards, if the positioning pin can be completely aligned and enters the riveting jack 1-1, the spring 6-3-2 is driven to move downwards by the compressed part of the second guide rod 7-8, the positioning pin 6-3 is unfolded again in the downward moving process, the distance between the positioning pin 6-3 and the second guide rod 7-8 is further kept unchanged, the upper end of the second guide rod 7-8 still keeps contact with the third slide rod 6-3-1, the position sensor controls the power supply of the second driving mechanism to keep a power-on state, and the subsequent riveting mechanism can work normally when needing to work; if the positioning pin 6-3 cannot be completely aligned and enter the riveting jack 1-1, the downward moving distance of the positioning pin 6-3 is relatively small, the amount of compression of the spring 6-3-2 by the second guide rod 7-8 cannot be completely compensated, the distance between the positioning pin 6-3 and the second guide rod 7-8 is relatively reduced in an initial state, the third slide rod 6-3-1 is displaced upwards relative to the first guide rod 7-7, the upper end of the second guide rod 7-8 is separated from the upper end of the third slide rod 6-3-1, the position sensor controls the power supply of the second driving mechanism to be in a power-off state, and the subsequent riveting mechanism cannot normally work when needing to work);

When the sliding mechanism works, the second guide rod 7-8 moves downwards along with the sliding block 7-5 along with the detection and adjustment of the detection mechanism until the detection and adjustment of the detection mechanism are completed, the sliding block 7-5 moves to the lowest part, at the moment, the lower end of the second guide rod 7-8 contacts and downwards extrudes the sliding plate 6-2, so that the sliding plate 6-2 generates downward pressure, and further, a large friction force is generated between the sliding plate 6-2 and the inner wall of the sliding shell 6-1, so that the position of the sliding plate 6-2 relative to the sliding shell 6-1 is limited, and the sliding plate 6-2 is prevented from sliding relative to the sliding shell 6-1 in subsequent work; (as shown in fig. 2), and because the track of the second chute 7-5-2 is a horizontal rightward track, the height of the second guide rod 7-8 is kept unchanged in the subsequent rightward movement process of the sliding shell 6-1, and the sliding plate 6-2 is always limited;
the limit of the sliding plate 6-2 is completed by using a simple mechanical structure, so that the maintenance of related components of the equipment is simple, and the equipment runs stably.
As a further scheme of the invention, the end cover mounting frame comprises a supporting mechanism 5-1, the motor end cover 1 is placed on the upper end face of the supporting mechanism 5-1, clamping hands 5-2 are elastically and slidably mounted on the periphery of the supporting mechanism 5-1, and the clamping hands 5-2 are used for clamping and fixing the motor end cover 1.
When the motor end cover fixing device works, the motor end cover 1 is directly placed into the four clamping hands 5-2 from the middle positions of the four clamping hands 5-2 above the supporting mechanism 5-1 and is fixed through the elastic force of the four clamping hands 5-2 to the center position of the supporting mechanism 5-1;
the elastic piece is used for fixing the motor end cover 1, so that the motor end cover 1 is installed more quickly and conveniently, and the operation efficiency of the equipment is improved.
It should be noted that: in all the schemes, the operation and the stop of the related driving mechanism are controlled by an external control circuit.
