[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0023] like Figures 1 to 5 As shown, an automotive wiring harness elbow crimping device includes a base plate 1;

[0024] A supplementary plate 20 is provided on the surface of the base plate 1. Multiple clamping cone plates 16 are evenly distributed in a ring on one side of the supplementary plate 20. A sliding connecting block 18 is fixed on one side of each of the multiple clamping cone plates 16. A fixing rod 17 is slidably connected to the surface of the sliding connecting block 18. The fixing rod 17 is fixedly installed in a groove opened on the surface of the supplementary plate 20. A second spring 19 is sleeved on the surface of the fixing rod 17. One end of the second spring 19 abuts against the surface of the sliding connecting block 18, and the other end of the second spring 19 abuts against the groove opened on the surface of the supplementary plate 20. An L-shaped sliding pull rod 10 is slidably connected to the surface of the supplementary plate 20. A pressure sleeve 14 is installed on one end of the L-shaped sliding pull rod 10. A cone groove 15 is opened on the surface of the pressure sleeve 14.

[0025] The clamping cone plates 16, which are evenly distributed in a ring on one side of the supplementary plate 20, can wrap the wire harness in all directions to achieve precise positioning. This prevents the wire harness from moving arbitrarily during crimping, ensuring that the crimping position is accurate every time. This greatly improves the crimping quality and reduces defective products caused by positioning deviations.

[0026] Furthermore, a fixed guide 12 is slidably connected in the through hole opened on the surface of the supplement plate 20. The fixed guide 12 is fixedly installed on the surface of the base plate 1. A spring 13 is installed on the surface of the fixed guide 12. One end of the spring 13 abuts against the supplement plate 20, and the other end of the spring 13 abuts against the surface of one end of the fixed guide 12.

[0027] When the wire harness is clamped between multiple clamping cones 16, as the pressure continues, the locating plate 20 can continue to slide to one side on the surface of the fixed guide 12, and the spring 13 is compressed. At this time, the cable clamped in the multiple clamping cones 16 can continue to move with the locating plate 20, so that one end of the wire harness can be inserted more tightly into the connecting elbow, increasing the contact area between the wire harness and the connecting elbow, ensuring the consistency and stability of each crimping, thereby improving the yield of the wire harness and reducing the increase in production costs caused by wire harness damage. Example 2

[0028] Improvements based on Example 1:

[0029] Furthermore, a U-shaped frame 2 is installed on the surface of the base plate 1, and a hydraulic rod 3 is installed on the surface of the U-shaped frame 2. The piston end of the hydraulic rod 3 passes through the U-shaped frame 2 and extends into the U-shaped frame 2, and is connected to the connecting slide plate 4 which is slidably connected in the U-shaped frame 2. A diagonal rod 8 is fixedly installed on the bottom surface of the connecting slide plate 4, and a fixing block 11 is fixedly installed on one end surface of the L-shaped sliding pull rod 10. The diagonal rod 8 is slidably connected in the diagonal hole opened on the surface of the fixing block 11.

[0030] The U-shaped frame 2 installed on the base plate 1 provides a stable support structure for the hydraulic rod 3. As the main power source, the piston end of the hydraulic rod 3 passes through the U-shaped frame 2 and is connected to the connecting slide plate 4. This structural design can ensure that the strong pressure generated by the hydraulic rod 3 is stably transmitted to the connecting slide plate 4, providing sufficient and stable power support for the subsequent crimping action and ensuring that the crimping process can be completed smoothly.

[0031] Furthermore, a lower pressure seat 6 is installed on the surface of the base plate 1 and inside the U-shaped frame 2. An inner recess 7 is fixed on the surface of the lower pressure seat 6, and an upper pressure block 5 is fixedly installed on the bottom surface of the connecting slide plate 4.

[0032] The recessed part 7 can closely fit the contour of the wire harness bend, providing all-round support for the bend during the crimping process and preventing the bend from deforming or shifting under pressure. The cooperation between the upper pressure block 5 and the recessed part 7 further ensures that the connection between the wire harness and the bend is tight and uniform. When the connecting slide plate 4 moves downward under the drive of the hydraulic rod 3, the upper pressure block 5 can accurately cooperate with the recessed part 7. This precise positioning design ensures that the crimping force is evenly and concentratedly applied to the connection part between the wire harness bend and the wire harness, which greatly improves the efficiency and quality of crimping and ensures that every crimping achieves the best results.

[0033] Furthermore, the surface of the lower pressure seat 6 is provided with a placement groove 9 for placing the elbow.

[0034] The shape of the placement groove 9 matches the bend of the wire harness to be crimped, providing precise positioning for the bend. When the operator places the bend of the wire harness into the placement groove 9, the bend can quickly and accurately reach the preset crimping position without additional adjustment and calibration, which greatly improves the accuracy and consistency of crimping. This helps to ensure that the connection between the wire harness and the bend is precisely aligned each time crimping, thereby improving the crimping quality and reducing the production of defective products due to positioning deviation.

[0035] Furthermore, the inner surface of the clamping cone plate 16 and the inner surface of the concave part 7 are integrally formed with anti-slip protrusions.

[0036] The anti-slip protrusions on the inner surface of the clamping cone plate 16 increase the friction between the clamping cone plate 16 and the outer sheath of the wire harness when the wire harness is clamped. This makes the clamping cone plate 16 more secure in fixing the wire harness. Even if there is a large external force during the crimping process, the wire harness is unlikely to slip or shift, ensuring the accuracy of the wire harness position before and during crimping, providing a basic guarantee for high-quality crimping. The anti-slip protrusions on the inner surface of the concave part 7 can cause the elbow to be squeezed and deformed, and the anti-slip protrusions can also extrude a pattern on the outer surface of the guide elbow, which helps to improve the stability of the wire harness elbow after crimping.

[0037] Working principle: In use, firstly, the automotive wiring harness elbow to be crimped is placed in the placement groove 9 opened on the surface of the lower pressure seat 6. Since the placement groove 9 is designed according to the shape of the elbow, it can effectively position the elbow initially and ensure its accuracy. Then, one end of the wiring harness is passed through the pressure sleeve 14 and the supplement plate 20, so that one end of the wiring harness is inserted into the elbow. Then, the hydraulic rod 3 installed on the surface of the U-shaped frame 2 is activated. The piston end of the hydraulic rod 3 begins to extend, pushing the connecting slide plate 4 connected to it to move downward in the U-shaped frame 2. As the connecting slide plate 4 descends, the inclined rod 8 fixed on its bottom surface also moves downward. The inclined rod 8 is slidably connected to the inclined hole opened on the fixing block 11 fixed on one end of the L-shaped sliding pull rod 10. This allows the inclined rod 8 to push the fixing block 11 through the inclined hole when it moves downward, thereby driving the L-shaped sliding pull rod 10 to slide along the surface of the supplement plate 20.

[0038] During the sliding of the L-shaped sliding rod 10, the pressure sleeve 14 installed at one end gradually approaches the clamping cone plate 16. The surface of the pressure sleeve 14 is provided with a cone groove 15. As the pressure sleeve 14 approaches, the cone groove 15 interacts with the clamping cone plate 16. Since the clamping cone plate 16 is slidably connected to the fixing rod 17 fixed in the groove of the supplementary plate 20 through the sliding connecting block 18, and the surface of the fixing rod 17 is provided with a spring 19, under the push of the pressure sleeve 14, the clamping cone plate 16 moves along the fixing rod 17 towards the wire harness bend, while compressing the spring 19. Multiple clamping cone plates 16 are evenly distributed in a ring on one side of the supplementary plate 20. They gradually approach the wire harness from different directions and clamp it tightly. The anti-slip protrusion integrally formed on the inner surface of the clamping cone plate 16 increases the friction with the wire harness bend and prevents slippage during the crimping process.

[0039] At the same time, the upper pressure block 5 on the bottom surface of the connecting slide plate 4 also gradually approaches the inner concave part 7 on the lower pressure seat 6 as the connecting slide plate 4 descends. The inner concave part 7 is fixed on the surface of the lower pressure seat 6 and is set opposite to the upper pressure block 5. The inner surface of the inner concave part 7 is also integrally formed with anti-slip protrusions. When the connecting slide plate 4 continues to descend, the upper pressure block 5 contacts the inner concave part 7 and performs a crimping operation on the wire harness bend located between the two. During the crimping process, due to the presence of the inner concave part 7, the upper pressure block 5, and the anti-slip protrusions on the inner surface of the inner concave part 7, the stability and firmness of the crimping can be guaranteed, so that the wire harness bend and the wire harness can be tightly connected.

[0040] After the crimping is completed, the piston end of the hydraulic rod 3 is reset, which causes the upper pressure block 5 to detach from the surface of the elbow. At the same time, the L-shaped sliding rod 10 slides back to reset, while the multiple clamping cone plates 16 can be reset and expand outward under the elasticity of the spring 19, preparing for the next crimping operation.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
