[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described below in conjunction with specific embodiments. The accompanying drawings are for illustrative purposes only, representing schematic diagrams rather than actual physical objects, and should not be construed as limiting the scope of this patent. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art.

[0020] like Figures 1 to 4 As shown, this utility model provides a clamping mechanism with a guide, including a base 1, a retaining seat 2, a wire clamping seat 3, and a cylinder 4. The base 1 has a vertical plate on its top. The retaining seat 2 is disposed on the front side of the vertical plate of the base, and its top is higher than the top of the vertical plate of the base. The retaining seat 2 has a rectangular through groove 21 that extends through its front and rear sides. A guide tube seat 5 is movably disposed in the rectangular through groove 21. The guide tube seat 5 has a wire hole 51 that extends through its front and rear sides. A guide tube 6 for wire harnesses to pass through is disposed at the front end of the wire hole 51 of the guide tube seat 5. The wire clamping seat 3 is disposed on the top surface of the vertical plate of the base 1, and its rear end extends out of the vertical plate. The pressure plate is designed with a straight plate. The pressure plate 3 has a wire inlet hole 31 extending through its front and rear sides, and the wire inlet hole 31 and the wire guide hole 51 are on the same central axis. The top of the pressure plate 3 has a pressure groove 32 extending through its left and right sides. The bottom surface of the pressure groove is lower than the wire inlet hole. An upper clamping claw 7 is fixed inside the pressure groove 32. The bottom surface of the pressure plate 3 has a positioning through hole 33 communicating with the pressure groove 32. The cylinder 4 is located at the bottom of the pressure plate 3, and its telescopic shaft has a lower clamping claw 8. The lower clamping claw 8 is located inside the positioning through hole 33, and its upper end extends into the pressure groove to cooperate with the upper clamping claw 7. The center line of the pressure groove is located on the left and right symmetrical line of the pressure plate. However, to accommodate other structures, the center line of the rectangular groove is located to the right of the left and right symmetrical line of the retainer, and the wire guide hole is located to the left of the left and right symmetrical line of the guide tube seat, thus ensuring that the wire guide hole and the guide tube on the guide tube seat are on the same central axis as the wire inlet hole of the pressure plate 3.

[0021] The conduit is fixed inside the wire hole of the conduit seat. The front end of the conduit seat 5 has symmetrically arranged threaded through holes on both sides, communicating with the wire hole. The rear end of the conduit 6 has a circumferentially circumferentially formed an annular groove 61. Two screws are inserted from the threaded through holes at the front end of the conduit seat into the annular groove of the conduit to lock the conduit in place. Furthermore, the internal through holes of the conduit consist of a large-diameter circular through hole, a tapered through hole, and a small-diameter circular through hole connected sequentially from back to front. The small-diameter circular through hole is equal to or slightly larger than the wire diameter, further ensuring accurate wire positioning.

[0022] When processing wires in wire harness processing equipment, the default wire entry height should be set slightly higher than the stamping height to ensure the wire can smoothly enter the crimping area. To ensure the wire maintains the correct position and posture during processing, the guide tube seat is movable. Other workpieces will press down on the front end of the guide tube seat, causing it to tilt slightly, thus bringing the wire leading from the guide tube closer to the processing position. Specifically, the lower rear end of the guide tube seat 5 is movably mounted in the rectangular through groove 21 of the retaining seat via a pin 9, and can rotate relative to it. A spring 10 is vertically mounted at the front end of the retaining seat 2, with the top of the spring 10 positioned at the bottom of the front end of the guide tube seat 5. A screw 11 is threadedly connected to the top front end of the retaining seat 2, and the screw 11 passes into the rectangular through groove 21 and abuts against the top surface of the guide tube seat 5. Here, the guide tube seat and guide tube can swing up and down under the action of the spring, pin, and screw, facilitating subsequent crimping and solving the problem of the guide tube 4 needing to swing up and down during subsequent crimping. Adjusting the extension length of the screw can adjust the swing angle of the guide tube.

[0023] In this embodiment, the upper and lower grippers cooperate as follows: The upper gripper 7 has a clamping channel 71 corresponding to the wire inlet hole 31, the clamping channel 71 extending through the front and rear sides of the upper gripper 7, and the bottom of the upper gripper 7 has a clearance guide groove 72 extending through its front and rear sides, and the clearance guide groove 72 is connected to the clamping channel 71; the lower gripper 8 is located inside the positioning through hole 33, and its upper end extends into the clearance guide groove 72 to cooperate with the clamping channel 71 of the upper gripper 7.

[0024] Furthermore, the lower gripper 8 includes a limiting plate 82 and a lower clamping plate 83 disposed on top of the limiting plate 82. The lower end of the limiting plate 82 is provided with a connecting shaft 81 connected to the cylinder telescopic shaft. The connecting shaft, limiting plate, and lower clamping plate of the lower gripper are integrally formed. Correspondingly, the positioning through hole 33 of the wire clamping seat includes a cylindrical channel and a lower clamping plate channel disposed above the cylindrical channel. The lower parts of the limiting plate 82 and the lower clamping plate 83 of the lower gripper 8 are located in the cylindrical channel, and the upper part of the lower clamping plate 83 extends from the cylindrical channel and the lower clamping plate channel into the clearance guide groove 72 of the upper gripper. In addition, the top surface of the lower clamping plate 83 is a concave-convex surface, which is used to increase friction, especially effective when clamping smooth wires, and can ensure that the wires will not easily slip during the clamping process.

[0025] like Figures 1-3 The diagram shows the clamping mechanism in its stationary state. At this time, the lower jaw 8 is located within the positioning channel, and its lower clamping plate 83 extends from the positioning channel 33 into the clearance guide groove 72 of the upper jaw 7, engaging with the clamping channel 71 of the upper jaw 7. When the cylinder 4 actuates, its telescopic shaft pushes the lower jaw 8 upward along the positioning channel 33. The lower clamping plate 83 of the lower jaw 8 enters the clamping channel 71 from the clearance guide groove 72 of the upper clamping plate 7, with the wire positioned between the top surface of the upper clamping plate and the inner top surface of the clamping channel, thus achieving clamping.

[0026] Meanwhile, the bottom of the upper gripper 7 is provided with several weight-reducing grooves 73 that extend through its left and right sides. The weight-reducing grooves 73 are connected to the clamping channel 71 and the clearance guide groove 72. The top of the weight-reducing grooves 73 is flush with the top of the clamping channel 71. The design of the weight-reducing grooves also facilitates the observation of the fit between the lower gripper and the upper gripper during manufacturing.

[0027] Furthermore, considering that the front side of the guide seat 5 will tilt slightly during stamping, in order to ensure that the wires located adjacent to the guide seat and the wire clamping seat do not bend when the other end of the guide seat is slightly raised, the wire hole 51 of the guide seat 5 and the wire inlet hole 31 of the wire clamping seat 3 are both flared holes at their closest points.

[0028] Furthermore, the base 1 has a sliding groove adapted to the guide rail, and the base 1 is movably mounted on the guide rail 12 through the sliding groove. This design allows the entire mechanism to move back and forth.

[0029] In use, this clamping mechanism is positioned appropriately on the wire harness processing equipment. The wire enters from the rear end of the wire inlet hole of the wire clamping seat, passes through the clamping channel of the upper jaw and the front wire inlet hole of the wire clamping seat, and enters the wire hole of the guide seat. It is then led out from the guide and extends a certain distance. After the wire is threaded, the clamping mechanism is stationary. The wire moves forward to the stamping position, and the cylinder of this mechanism is activated. Its telescopic shaft extends, causing the lower jaw to move upward. Under the action of the wire clamping seat and the lower clamping plate, the lower jaw clamps the upper jaw. That is, the lower clamping plate moves upward from the clearance guide groove of the upper jaw and cooperates with the clamping channel of the upper jaw to clamp the wire. Other workpieces will press down and touch the front end of the guide seat, causing the guide to lower slightly. The wire moves downward close to the processing position to achieve stamping. After stamping is completed, the other workpieces return, the guide seat resets under the action of the spring, the telescopic shaft of the cylinder retracts, causing the lower jaw to move downward, and its lower pressure plate returns to the clearance guide groove of the upper jaw, thus opening the lower jaw and the upper jaw.
