The riveting block 3 is vertically slidably mounted on the machine body 1. An upper blade 4 is fixed to the bottom of the riveting block 3. The upper blade 4 cooperates with a lower blade 5 fixed on the machine body 1. The upper blade 4 is located directly above the lower blade 5. A servo motor 21 is provided inside the pressing mechanism 2. The servo motor 21 can control the vertical movement speed of the upper blade 4, thereby controlling the riveting speed of the terminal. The pressing mechanism 2 drives the upper blade 4 to reciprocate vertically. By reciprocating vertically and intermittently cooperating with the lower blade 5, the upper blade 4 can complete the intermittent riveting of the wire and terminal, reduce the riveting time of the terminal, and improve the riveting efficiency of the riveting machine.

[0028] The feeding mechanism 7 has one end fixedly connected to one side of the riveting block 3, and the other end of the feeding mechanism 7 is horizontally slidably mounted on the machine body 1. The feeding mechanism 7 moves vertically back and forth with the riveting block 3. Through the reciprocating motion, the feeding mechanism 7 can intermittently and continuously transmit the terminal to the mating point of the upper blade 4 and the lower blade 5, so that the upper blade 4 and the lower blade 5 can quickly rivet the terminal onto the wire, thereby further improving the riveting efficiency of the riveting machine.

[0029] In this embodiment, the servo motor 21 can reach a speed of 3000-5000 r / min, compared to the asynchronous three-phase motor in the existing riveting machine, which can only reach a speed of 600-1000 r / min. The servo motor 21 can freely adjust its speed during the riveting acceleration and deceleration stages, thereby improving the riveting efficiency of the riveting machine and reducing the riveting time.

[0030] like Figs. 1-3As shown, as a preferred embodiment of the utility model, the lower pressing mechanism 2 includes rotating block 22, sliding block 23, lifting block 24, horizontal sliding slot 25, sliding seat 26 and connecting column 27, the rotating block 22 is rotatably installed on the body 1, one side of the rotating block 22 is connected with the output end of servo motor 21, the other end of the rotating block 22 is eccentric and rotatably connected with the sliding block 23, the sliding block 23 is slidably installed in the horizontal sliding slot 25 of the lifting block 24, the lifting block 24 is vertically slidably installed in the sliding seat 26, the sliding seat 26 is fixed on the body 1, the bottom of the lifting block 24 is fixed with the connecting column 27, and the connecting column 27 is fixedly connected with the riveting block 3.

[0031] In the embodiment, the servo motor 21 drives the rotating block 22 to rotate, the rotating block 22 drives the sliding block 23 to reciprocatingly lift and reciprocatingly slide in the horizontal sliding slot 25, the sliding block 23 drives the lifting block 24 to reciprocatingly vertically move, and the lifting block 24 drives the upper knife 4 to reciprocatingly vertically move through the connecting column 27, so that the intermittent riveting of the wire and the terminal can be completed through the reciprocating vertical movement of the upper knife 4 and the intermittent cooperation with the lower knife 5, the riveting time of the terminal is reduced, and the riveting efficiency of the riveting machine is improved.

[0032] In a preferred embodiment, during the upward movement of the sliding block 23, the rotating speed of the servo motor 21 can be adjusted through the control program to control the sliding block 23 to slowly move upward, in the process, the wire is fed and discharged, when the next group of riveting wires is in place, the control program controls the servo motor 21 to accelerate, so that the sliding block 23 quickly moves downward, and then drives the upper knife 4 to quickly move downward to complete the riveting of the terminal, so that the riveting time is reduced and the riveting efficiency is improved.

[0033] The highest position of the sliding block 23 is set as the A position, and the position of the sliding block 23 when the connection between the sliding block 23 and the rotating block 22 is rotated to the same horizontal plane as the center of the rotating block 22 is set as the B position, after the riveting of the wire is completed, the riveted wire can be moved only when the sliding block 23 moves to near the A position, during the movement of the wire to be riveted to the riveting position, the sliding block 23 moves from the A position to the B position, which can avoid the collision between the wire and the upper knife 4 during the movement, and reduce the defective rate, and during the above process, the servo motor 21 is always not stopped.

[0034] When the asynchronous three-phase motor is used, the sliding block 23 can only wait at the A position, at this time, the asynchronous three-phase motor is in a stopped state, and after the riveting wire moves to the riveting position, the asynchronous three-phase motor starts from zero and accelerates to drive the sliding block 23 to move downward from the A position, so that the riveting of the terminal is completed, which will cause the riveting speed to be slow, and then cause the riveting efficiency to be poor.

[0035] As Figs. 1-3As shown, in a preferred embodiment of the present invention, the feeding mechanism 7 includes a reciprocating component 71, a feeding component 72, and a control block 73. One end of the reciprocating component 71 is fixedly connected to one side of the riveting block 3, and the other end of the reciprocating component 71 is horizontally slidably mounted on the machine body 1. The feeding component 72 is installed at the bottom of the reciprocating component 71, and the feeding component 72 intermittently abuts against the terminal and the control block 73 fixed on the worktable 6.

[0036] like Figs. 1-3 As shown, in a preferred embodiment of the present invention, the reciprocating assembly 71 includes a connecting block 711, a pulley 712, a reciprocating block 713, and an L-shaped groove 714. One end of the connecting block 711 is fixed to one side of the riveting block 3, and the pulley 712 is rotatably mounted on the other end of the connecting block 711. The pulley 712 slides in cooperation with the L-shaped groove 714 opened on the reciprocating block 713. The reciprocating block 713 is horizontally slidably mounted on the machine body 1, and a feeding assembly 72 is installed at the bottom of the reciprocating block 713.

[0037] In this embodiment, during the upward movement of the rivet block 3, the rivet block 3 drives the connecting block 711 and the pulley 712 to move upward. In the initial state, the pulley 712 slides and engages with the bottom end of the L-shaped groove 714. By moving upward and engaging with the L-shaped groove 714, the pulley 712 can drive the reciprocating block 713 to slide towards the upper blade 4. The reciprocating block 713 drives the terminal to move towards the wire through the feeding assembly 72, thereby completing the feeding of the terminal.

[0038] During the downward movement of the riveting block 3, the riveting block 3 drives the connecting block 711 and the pulley 712 to move downward. The pulley 712, through its downward movement and cooperation with the L-shaped groove 714, can slide the reciprocating block 713 away from the upper blade 4. The reciprocating block 713 drives the feeding assembly 72 to move backward. The feeding assembly 72, through its cooperation with the control block 73, can release the control of the terminal during the backward movement, so that the feeding assembly 72 can quickly move to the required position, which facilitates the feeding assembly 72 to quickly feed the terminal of the next stage, thereby completing the intermittent and continuous feeding of the terminal, improving the riveting efficiency of the riveting machine, and reducing the riveting time.

[0039] like Figs. 1-3 As shown, in a preferred embodiment of the present invention, the feeding assembly 72 includes a mounting base 721, a pressing block 722 and a feeding block 723. The mounting base 721 is fixed to the bottom of the reciprocating block 713. The pressing block 722 is rotatably mounted on the mounting base 721. One end of the pressing block 722 is fixed with the feeding block 723, which is intermittently engaged with the control block 73 and the terminal.

[0040] like Figs. 1-3As shown, as a preferred embodiment of the utility model, the feeding block 723 and the control block 73 are both preferably a trapezoidal block structure, and the end surfaces of the feeding block 723 and the control block 73 that slide with each other are all inclined end surfaces, so that the feeding block 723 can be quickly slid to the top of the control block 73, thereby realizing intermittent feeding of the terminal.

[0041] In the embodiment, when the feeding block 723 moves backward, the control block 73 deflects the pressing block 722 through the feeding block 723, so that the feeding block 723 is separated from the terminal, thereby releasing the control of the terminal and facilitating quick feeding of the terminal in the next stage;

[0042] When the feeding block 723 moves forward, the pressing block 722 deflects the feeding block 723 in the reverse direction through gravity, so that the feeding block 723 is again in contact with the terminal and drives the terminal to move in the direction close to the wire, thereby completing the feeding of the terminal.

[0043] The working principle of the utility model is:

[0044] The servo motor 21 drives the rotating block 22 to rotate, the rotating block 22 drives the sliding block 23 to reciprocatingly lift and drive the sliding block 23 to reciprocatingly slide in the horizontal sliding groove 25, the sliding block 23 drives the lifting block 24 to reciprocatingly vertically move, the lifting block 24 drives the upper knife 4 to reciprocatingly vertically move through the connecting column 27, and the upper knife 4 can complete intermittent riveting and pressing of the wire and the terminal through the reciprocating vertical movement and intermittent cooperation with the lower knife 5.

[0045] The highest position of the sliding block 23 is set as the A position, the position of the sliding block 23 when the connecting part of the sliding block 23 and the rotating block 22 is rotated to the same horizontal plane as the center of the rotating block 22 is set as the B position, when the wire completes riveting and pressing, the wire that has completed riveting and pressing can be moved only when the sliding block 23 moves to the vicinity of the A position, in the process of moving the wire to be riveted and pressed to the riveting and pressing position, the sliding block 23 moves from the A position to the B position at this time, so that the collision between the wire and the upper knife 4 in the moving process can be avoided, and the defective product rate is reduced.

[0046] In the process of moving the riveting and pressing block 3 upward, the riveting and pressing block 3 drives the connecting block 711 and the pulley 712 to move upward, the pulley 712 is in sliding cooperation with the bottom end of the L-shaped groove 714 in the initial state, the pulley 712 can drive the reciprocating block 713 to slide in the direction close to the upper knife 4 through the upward movement and cooperation with the L-shaped groove 714, the reciprocating block 713 moves forward through the pressing block 722 and the feeding block 723, the pressing block 722 drives the feeding block 723 to deflect in the reverse direction through gravity, so that the feeding block 723 is again in contact with the terminal and drives the terminal to move in the direction close to the wire, thereby completing the feeding of the terminal.

[0047] During the moving down of the riveting block 3, the riveting block 3 drives the connecting block 711 and the pulley 712 to move down, the pulley 712 drives the reciprocating block 713 to slide away from the upper knife 4 through the mode of moving down and cooperating with the L-shaped slot 714, the reciprocating block 713 drives the pressing block 722 and the feeding block 723 to move backward, the control block 73 drives the pressing block 722 to deflect through the feeding block 723, so that the feeding block 723 is separated from the terminal, thereby releasing the control of the terminal, and facilitating the rapid feeding of the terminal in the next stage;
