Description

Technical Field

[0001] The invention relates to the technical field of wire harness crimping equipment, in particular to a pressing force regulating mechanism of a guide device for wire harness crimping. Background Art

[0002] Wire harness crimping equipment is a professional tool used to connect multiple strands of wires or cables. It usually includes a crimping head and a crimping tool, which firmly connects the conductor to the insulating part by applying pressure to ensure reliable electrical connection and circuit communication. This is widely used in the fields of manufacturing and maintenance of electronic equipment, automotive electrical systems, aerospace equipment, etc. The function of wire harness crimping is to crimp the contact terminal (connector) made of copper material with the wire and cable, and then mold the insulator or metal shell on the outside, and the components connected to the circuit are bundled with wire harnesses.

[0003] Since most existing wire harness crimping equipment lacks an effective adjustment mechanism in the guide clamping device during use, the clamping stroke and force are the same and cannot be changed according to different wire harness types and thicknesses, resulting in a single clamping method that lacks adjustability and adaptability. Summary of the invention

[0004] The problem to be solved by the present invention is that the pressing force of the pressing device of the wire harness crimping guide structure is inconvenient to adjust.

[0005] In order to solve the above technical problems, the technical solution of the present invention is: a pressing force adjustment mechanism of a guide device for wire harness crimping, comprising a shell, a partition is provided at the bottom of the shell, a box is fixedly connected to the bottom of the partition, both sides of the box are provided with slots, a transparent plate is provided on the front of the box, a control structure is provided inside the shell, and a linkage structure is provided on one side of the bottom of the inner wall of the shell, and the linkage structure can be used in conjunction with the control structure;

[0006] The control structure includes a pressure rod, a reinforcement block, a threaded sleeve, a knob, a linkage plate, a rotating block, a connecting block, a labor-saving rod, a moving block, a threaded rod and a travel plate. When the knob applies a rotational force, the knob can control the moving block to move horizontally through the threaded rod. After the moving block is subjected to the force, the linkage plate can control the connecting block to drive the rotating block to rotate around the center of a circle.

[0007] Preferably, a pressure rod is provided inside the shell, and a reinforcement block is fixedly connected to the top of one side of the pressure rod, and a threaded sleeve is fixedly connected to the bottom of the reinforcement block. One side of the threaded sleeve penetrates the shell and extends to the outside of the shell, and one side of the inner wall of the threaded sleeve is rotatably connected to a threaded rod, and the other side of the threaded rod penetrates the threaded sleeve and extends to the outside of the threaded sleeve, and a knob is fixedly connected to one side of the threaded rod, and the four sides of the knob are fixedly connected to labor-saving rods.

[0008] Preferably, a moving block is provided on the threaded rod, the back side of the moving block passes through the threaded sleeve and extends to the outside of the threaded sleeve, the back side of the moving block is rotatably connected to a linkage plate, and a through groove is provided on the surface of the linkage plate.

[0009] Preferably, the front side of the pressure rod is penetrated by a rotating block, the front side of the rotating block is fixedly connected to a travel plate, the back side of the rotating block is fixedly connected to a connecting block, the connecting block is adapted to the through groove, the bottom of the pressure rod penetrates the outer shell, the partition and the box body in sequence and extends to the interior of the box body, and the bottom of the pressure rod is fixedly connected to an extrusion plate.

[0010] Preferably, a linkage structure is also provided inside the shell, and the linkage structure includes a base, a sliding rod, a bracket, a motor, a rack, a gear, a control block, a roller, a limit shell and a limit ring. When the motor can drive the rack to move horizontally through the gear, the rack will drive the control block to move horizontally after being subjected to force, and the control block can control the pressure rod to move vertically up and down by cooperating with the stroke plate.

[0011] Preferably, a base is fixedly connected to one side of the bottom of the inner wall of the shell, a motor is fixedly connected to the top of the base, a gear is fixedly connected to the front of the motor, a limiting shell is fixedly connected to the top of the front of the base, a rack is slidably connected to the bottom of the limiting shell, and the rack is meshed with the gear.

[0012] Preferably, a control block is fixedly connected to one side of the rack, an inclined groove is provided on the back of the control block, the inclined groove is adapted to the stroke plate, rollers are rotatably connected to both sides of the inner wall of the inclined groove, and a sliding rod is fixedly connected to the other side of the control block.

[0013] Preferably, one side of the sliding rod passes through the outer shell and extends to the outside of the outer shell, and the other side of the bottom of the inner wall of the outer shell is fixedly connected to a bracket, and the top of the bracket is fixedly connected to a limiting ring, and a limiting groove is provided on one side of the limiting ring, and the limiting groove is adapted to the sliding rod.

[0014] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0015] (1) A control structure is provided inside the shell. The control mechanism can adjust the downward travel distance of the pressure rod through the cooperation between the threaded rod, the linkage plate and the pressure rod. It can be freely adjusted according to the different types and thicknesses of wire harnesses. The linkage plate can control the downward movement distance through its own tilt angle. The tilted downward movement method is relatively stable and can be more convenient when crimping the wire harness. The threaded rod can adjust the tilt angle of the linkage plate. The adjustment is quick and convenient and will not take up too much operating time. There is also a labor-saving rod on the knob to save the user more effort when rotating the threaded rod. Even without the help of external tools, it can be quickly and effectively controlled. The extrusion plate at the bottom of the pressure rod is flush with the internal space of the box. This further increases its movement stability when it moves downward. A transparent plate is provided on the front of the box. The transparent plate allows the user to observe the compression of the wire harness in the box.

[0016] (2) A linkage structure is also provided inside the housing. The linkage structure can drive the control block to move by controlling the rack through the motor. The control block can control the pressure rod to move downward to compress the wiring harness through the extrusion plate. The power source of the linkage structure is completed by a motor, and it does not need to be connected to an additional control end, which saves more energy and electricity. The linkage structure controls the operation of the entire device, which adopts a large number of mechanical control structures. Compared with the precise electronic end control, it is more durable and its service life is greatly increased. A roller is provided on the control block. The roller can reduce the friction between the surface of the travel plate, so that the control block and the travel plate are in contact more smoothly and reduce the feeling of blockage.
