Description

Technical Field

[0001] This utility model relates to the field of wire harness straightening technology, specifically to a wire harness straightening mechanism for a wire harness terminal block machine. Background Technology

[0002] The wire harness straightening mechanism of the wire harness terminal machine is a device used to quickly straighten wire harnesses that are bent after unwinding, so as to facilitate subsequent terminal processing.

[0003] A search of Chinese Patent Publication No. CN 220692498 U, which describes a wire harness straightening mechanism for a wire harness terminal machine, reveals that the device includes a movable base frame. Two displacement slides are movably mounted inside the guide frame. A wire harness seat is fixedly mounted on the top of the displacement slides, and a wire harness guide groove is formed inside the wire harness seat. A clamping seat is movably mounted on the bottom of the top plate, and a winding frame is fixedly mounted on the top of the movable base frame. This invention uses two guide wheels inside the support frame to guide and support the wire harness. A side bracket mounts the guide frame. The guide frame contains a displacement slide driven by a displacement cylinder. The wire harness seat on top of the displacement slide supports the terminal wire harness. During straightening, the positions of the two displacement slides are adjusted, and then the clamping motor is activated. The clamping motor drives the clamping seat to descend, clamping and fixing the wire harness inside the wire harness guide groove. Then, the displacement cylinder drives the displacement slides to slide to both sides, straightening the fixed wire harness, thus facilitating subsequent terminal wire harness processing.

[0004] In existing technologies, the limiting groove on the guide wheel is fixed and cannot be adjusted. However, in actual wire harness processing, various wire harnesses with different diameters, shapes, and strand numbers are involved. If the size of the limiting groove is fixed, it can only be used for wire harnesses of specific specifications. For wire harnesses of other sizes, they either cannot be placed in the limiting groove or cannot be effectively limited after being placed, which can easily lead to shaking, displacement, and other issues, affecting the straightening accuracy. Therefore, a new structure is needed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a wire harness straightening mechanism for a wire harness terminal crimping machine, so as to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a wire harness straightening mechanism for a wire harness terminal machine, comprising:

[0007] A straightening assembly, comprising a first metal plate, a second metal plate, a driving wheel, and a driven wheel, wherein the driving wheel and the driven wheel are movably connected to the first metal plate and the second metal plate;

[0008] An adaptive adjustment assembly includes a first limiting ring and a second limiting ring. The first limiting ring is fixedly connected to one side of the driven wheel, and the second limiting ring is movably connected to the driven wheel.

[0009] Furthermore, the adaptive adjustment assembly also includes a T-shaped receiving rod, a first threaded groove, a retaining groove, and a first wing screw. The T-shaped receiving rod is fixedly connected to the side of the driven wheel. The first threaded groove is formed through the upper and lower ends of the T-shaped receiving rod. A retaining groove is formed on the second limiting ring. The first wing screw is movably connected between the first threaded groove and the retaining groove.

[0010] Furthermore, the adaptive adjustment component also includes a first rectangular block, a second rectangular block, a second threaded groove, and a second wing screw. The first rectangular block is fixedly connected to both sides of the first metal plate, and the second rectangular block is fixedly connected to both sides of the second metal plate. A second threaded groove is formed through the second rectangular block, and the second wing screw is movably connected in the second threaded groove.

[0011] Furthermore, the adaptive adjustment component also includes a circular hole and a T-shaped limiting rod. The circular hole is opened through the first rectangular block, and the T-shaped limiting rod is fixedly connected to the top of the second rectangular block. The T-shaped limiting rod is movably connected in the circular hole.

[0012] Furthermore, the straightening assembly also includes a cylindrical shaft, a motor, and a limiting shaft. The cylindrical shaft is movably connected to the first metal plate and the second metal plate. The cylindrical shaft is fixedly connected to the driving wheel. The motor is fixedly connected to the rear of the first metal plate and the second metal plate. The output end of the motor is connected to the cylindrical shaft. The limiting shaft is movably connected to the first metal plate and the second metal plate. The limiting shaft is fixedly connected to the driven wheel.

[0013] Furthermore, it also includes a height adaptation component, which includes a movable base, a telescopic cylinder, and a telescopic rod. The telescopic rod is fixedly connected to both sides of the bottom of the second metal plate, and the telescopic cylinder is movably connected to the outside of the telescopic rod. The movable base is fixedly connected to the bottom of the telescopic cylinder.

[0014] Furthermore, the height adaptation component also includes a third threaded groove, a strip groove, and a third wing screw. The third threaded groove is formed through the side of the telescopic cylinder, and the strip groove is formed on the telescopic rod. The third threaded groove and the strip groove are movably connected to the third wing screw.

[0015] This utility model has the following beneficial effects:

[0016] This invention allows for the adjustment of the size of the limiting groove between the second and first limiting rings by turning the first wing screw at the first threaded groove, which in turn pushes the second limiting ring on the driven wheel. Turning the second wing screw at the second threaded groove pushes the first rectangular block upward, thereby adjusting the gap between the driving and driven wheels on the first and second metal plates. This allows the invention to accommodate wire harnesses of different sizes and effectively limit their movement when straightening wire harnesses of different sizes, ensuring straightening accuracy.

[0017] Based on the aforementioned beneficial effects, by stretching the telescopic rod in the telescopic cylinder, the height of the second metal plate can be adjusted. At the same time, by tightening the third wing screw in the third threaded groove, the height adjustment can be fixed, thereby enabling the height adjustment of the driving and driven wheels, which can be moved to the same height as the wire feeding reel, thus ensuring the horizontal insertion of the wire harness.

When the gap between the driving wheel 103 and the driven wheel 104 at the upper and lower ends is adapted to the size of the wire harness, stop tightening the second wing screw 2010. Then tighten the first wing screw 206 at the first threaded groove 204 to push the first wing screw 306. The second limiting ring 202 moves towards the first limiting ring 201. When the distance between the limiting grooves formed between the first limiting ring 201 and the second limiting ring 202 is adapted to the wire harness size, the first wing screw 206 stops rotating. Then, the motor 106 is turned on, and the driving wheel 103 is driven to rotate under the action of the cylindrical shaft 105. Then, one end of the wire harness on the wire feed reel is inserted into one end of the driving wheel 103 and the driven wheel 104, and is located between the second limiting ring 202 and the first limiting ring 201. Then, the wire harness is straightened under the drive of the driving wheel 103 and the driven wheel 104. This step can adapt to wire harnesses of different sizes and can effectively limit them when straightening wire harnesses of different sizes, ensuring straightening accuracy.
