The present invention will be described in further detail with reference to the accompanying drawings.

In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "bottom" and "top," "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

A material clamping device of a wire harness production line is shown in figure 1 and comprises a clamping seat 1 connected with a main guide block, two clamping rods 11 used for clamping wires and a driving mechanism 12 driving the two clamping rods 11 to move, wherein the driving mechanism 12 can be connected with a cylinder fixed at the upper end of a rack. The grip slipper 1 uses the bolt fastening to keep away from its terminal surface of seting down the groove in main guide block, and two supporting rods 11 are located the both sides of grip slipper 1 respectively, and its lower extreme all is articulated with grip slipper 1, and both upper ends can butt mutually. The cylinder is used for driving the driving mechanism 12 to move, so that the two clamping rods 11 are driven to rotate, and the position of the electric wire is fixed.

As shown in fig. 1, the driving mechanism 12 includes a connecting piece 121 hinged to the clamping rods 11, and a driving block 122 for driving the connecting piece 121 to move simultaneously, wherein a driving rod 123 is connected to the lower end of the driving block 122 by using a bolt, the driving rod 123 passes through the clamping base 1 and can slide up and down, and the lower end of the driving rod can abut against the upper end of the air cylinder. One end of the connecting piece 121 is hinged to the side wall of the clamping rod 11, the other end of the connecting piece is hinged to the side wall of the driving block 122, and the hinge point of the connecting piece 121 and the clamping rod 11 is higher than the hinge point of the clamping rod 11 and the clamping seat 1. Utilize the cylinder to drive actuating lever 123 and remove to drive two supporting rods 11 and remove, utilize supporting rod 11 with the electric wire centre gripping, two supporting rods 11 can remove simultaneously under the drive of drive block 122 to make clamping device's use more convenient.

In order that the upper ends of the two clamping rods 11 can be moved away from each other when the piston rod of the cylinder pushes the driving rod 123 to ascend, as shown in fig. 1, the lower ends of the connecting pieces 121 respectively connected to the two clamping rods 11 are moved closer to each other, and the hinge point thereof to the clamping rods 11 is higher than the hinge point thereof to the driving block 122. When actuating lever 123 upwards removed under the promotion of cylinder, drive two connecting piece 121 lower extremes upwards removed to drive two supporting rod 11 upper ends and keep away from each other, can arrange the electric wire in between two supporting rod 11 this moment, no longer need with actuating lever 123 downstream, thereby make actuating mechanism 12's use more convenient.

In order to keep the balance of the forces applied by the connecting pieces 121 on both ends of the hinge shaft connected to the grip holder 1 when the clamping bar 11 rotates, the abrasion in both ends of the hinge shaft connected to the clamping bar 11 and the grip holder 1 is kept the same, and the clamping bar 11 can be more stable when clamping the electric wire. As shown in fig. 1, the connecting pieces 121 are four in number and are respectively disposed at both sides of the clamping bar 11. When drive clamping rod 11 rotates, connection piece 121 applys its pivoted power of messenger simultaneously to the both sides of clamping rod 11 to make clamping rod 11 keep balanced with the power that the articulated shaft both ends of grip slipper 1 junction received, thereby make the degree of wear of clamping rod 11 and grip slipper 1 junction keep the same, thereby make the relative position between the root of company clamping rod 11 that grip slipper 1 is connected can not change, and the centre gripping to the electric wire is more stable.

In order to fix the electric wire by using the clamping rods 11, the position between the electric wire and the clamping rods 11 is not changed, so that the process of clamping the electric wire by the clamping rods 11 is more stable. As shown in fig. 1, the end faces of the two clamping rods 11 close to each other are integrally formed with the abutting block 13, the end faces of the two abutting blocks 13 close to each other are provided with the clamping grooves 131 horizontally arranged, the longitudinal sections of the clamping grooves 131 are triangular, the abutting blocks 13 are perpendicular to the end faces of the clamping rods 11 and the hinged axis of the clamping base 1 and penetrate through the end faces, and the electric wires can be arranged in the two clamping grooves 131 at the same time. The relative position of the electric wire and the clamping rod 11 is limited by the clamping groove 131, so that the electric wire is not separated from the clamping rod 11, and the stability of the wiring harness processing is increased.

As shown in fig. 1, since the connection part of the clamping bar 11 and the clamping base 1 is worn after the clamping bar 11 is used for a long time, the clamping bar 11 is deviated, the direction of the electric wire clamped by the two clamping bars 11 is changed, and the core wire of the electric wire cannot be inserted into the terminal. Therefore, the end faces of the two abutting blocks 13 which are close to each other are provided with a plurality of limiting grooves 132 which are vertically arranged, and the limiting grooves 132 penetrate through the upper end faces and the lower end faces of the abutting blocks 13. A gap is left between the limiting grooves 132 on the same abutting block 13, and the end surfaces of two abutting blocks 13 abutting against each other can abut against the bottom surface of the limiting groove 132 on another abutting block 13. The relative position of the two abutting blocks 13 is limited by the limiting groove 132, so that the position of the electric wire clamped by the two abutting blocks is kept fixed, the core wire of the electric wire can be normally inserted into the terminal, and the using process of the production line is kept stable.

As shown in fig. 1, the reset mechanism 2 includes a reset rod 21 screwed to the holder 1, a reset spring 22 driving the holder 11 to reset, and a reset block 23 defining a position of the reset spring 22, the reset rod 21 passes through the holder 11 without contacting the holder 11, and an end thereof remote from the holder 1 is connected to the reset block 23. The reset spring 22 is sleeved on the reset rod 21, one end of the reset spring abuts against the end face, far away from the clamping seat 1, of the clamping rod 11, and the other end of the reset spring abuts against the end face, close to the clamping seat 1, of the reset block 23. The return spring 22 applies a force to the clamping bars 11 to rotate toward the clamping base 1, so that the two clamping bars 11 approach each other, thereby clamping the electric wire.

The working principle is as follows:

when the electric wire is processed, the main chain drives the clamping device to move, when the clamping seat 1 moves to the electric wire feeding position, the piston rod of the air cylinder moves upwards to drive the driving rod 123 to move upwards, and therefore the connecting piece 121 hinged to the driving block 122 is driven to rotate upwards. Because the lower ends of the clamping rods 11 are hinged with the clamping seat 1, the upper ends of the two clamping rods 11 are separated from each other when the two clamping rods are subjected to the force applied by the connecting sheet 121. At this moment, the electric wire is placed between the two clamping rods 11, then the piston rod of the air cylinder contracts, the clamping rods 11 move towards the clamping seat 1 under the action of the elastic force exerted by the reset spring 22, so that the electric wire is clamped by the two clamping rods 11, and the electric wire can be driven by the main chain to be processed.
