Description

Technical Field

[0001] This utility model relates to the field of tensile testing technology, specifically a tensile testing machine for processing automotive lamp wiring harnesses with a positioning structure. Background Technology

[0002] The automotive lighting wiring harness is the main network component of a vehicle's lighting circuitry, consisting of wires, connectors, and insulating tape. The reliability of the lighting wiring harness directly affects the safety and performance of the vehicle. Tensile testing is an important method for detecting the tensile strength of the lighting wiring harness.

[0003] However, in actual use, the above-mentioned equipment fixes the surface of the wire harness by using serrated clamps to adjust and tighten the surface of the wire harness with bolts. When performing tensile testing, the serrated shape can easily break the surface of the wire harness, affecting the test results. In view of this, we propose a tensile testing machine for processing automotive lamp wire harnesses with a positioning structure. Summary of the Invention

[0004] The purpose of this invention is to provide a tensile testing machine for processing automotive lighting wiring harnesses with a positioning structure, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tensile testing machine for processing automotive lighting wiring harnesses with a positioning structure, comprising a machine body, a column fixedly mounted on the surface of the machine body, a mounting bracket provided on the surface of the column, a tensile sensor fixedly connected to the lower surface of the mounting bracket via a connecting rod, a mounting plate fixedly connected to the lower surface of the tensile sensor via a connecting rod, a clamping mechanism provided on the surface of the machine body, and a promoting mechanism provided on the surface of the machine body, the clamping mechanism comprising: A threaded rod is threadedly connected to the inner wall of the mounting plate, and a clamping plate is rotatably mounted at the end of the threaded rod. A limit rod is fixedly mounted on the upper surface of the clamping plate. A winding cylinder is fixedly installed on the side wall of the mounting plate. The inner wall of the winding cylinder is threaded with a threaded nail, and a clamping ring is fixedly installed on the arc surface of the threaded nail.

[0006] Preferably, the promoting mechanism includes a groove formed on the side wall of the clamping plate, and a protrusion is fixedly installed on the inner wall of the groove.

[0007] Preferably, the groove is arc-shaped, and there are several grooves arranged in a linear array on the surface of the clamping plate.

[0008] Preferably, a limiting groove is formed at the upper end of the inner wall of the mounting plate, and a limiting rod is provided inside the limiting groove. The limiting rod slides inside the limiting groove, thereby restricting the clamping plate and preventing the clamping plate from rotating.

[0009] Preferably, the side wall of the mounting plate is provided with a threaded hole, and the inner wall of the threaded hole is threaded with a threaded rod, so that the threaded rod can adjust the distance of the clamping plate inside the mounting plate.

[0010] Preferably, the arc surface of the winding cylinder is provided with a threaded groove, which facilitates the winding of the wire harness inside the threaded groove to fix the wire harness.

[0011] Preferably, a second set of clamps with the same configuration as the clamping plate is provided below the mounting plate to facilitate fixing the two ends of the wire harness.

[0012] Compared with the prior art, this utility model provides a tensile testing machine for processing automotive lamp wiring harnesses with a positioning structure, which has the following beneficial effects: 1. This tensile testing machine for processing automotive lighting wiring harnesses with a positioning structure is equipped with a clamping mechanism. Both ends of the wiring harness are wound around the arc surface of the winding cylinder. Rotating the threaded pins fixes the ends of the wiring harness with the clamping ring, thereby ensuring the stability of the wiring harness. Next, adjusting the threaded rods clamps the wiring harness with the clamping plates, which facilitates subsequent tensile testing, ensures the stability of the wiring harness positioning and fixation, and reduces breakage caused by clamping damage to the arc surface of the wiring harness.

[0013] 2. This tensile testing machine for automotive lighting wiring harness processing, equipped with a positioning structure, features a facilitating mechanism and a groove to facilitate vertical positioning of the wiring harness, thereby making the tensile data of the wiring harness more accurate.

A limit rod 303 is fixedly mounted on the upper surface of the clamping plate 302. A winding cylinder 304 is fixedly mounted on the side wall of the mounting plate 7. A threaded nail 305 is threadedly connected to the inner wall of the winding cylinder 304, and a clamping ring 306 is fixedly mounted on the arc surface of the threaded nail 305.

[0018] In addition, the promoting mechanism 4 includes a groove 401, which is formed on the side wall of the clamping plate 302.

[0019] In this embodiment of the invention, a limiting groove is formed at the upper end of the inner wall of the mounting plate 7, and a limiting rod 303 is provided inside the limiting groove. The limiting rod 303 slides inside the limiting groove, thereby restricting the clamping plate 302 and preventing the clamping plate 302 from rotating. A threaded hole is formed on the side wall of the mounting plate 7, and a threaded rod 301 is threadedly connected to the inner wall of the threaded hole, so that the threaded rod 301 can adjust the distance of the clamping plate 302 inside the mounting plate 7. A threaded groove is formed on the arc surface of the winding cylinder 304, so as to facilitate the winding of the wire harness inside the threaded groove and fix the wire harness. Below the mounting plate 7, there is another set of clamps with the same configuration as the clamp 302, which facilitates the fixing of both ends of the wire harness. The outer side of the body 1 is connected to the computer on the outside through the connecting cable to obtain the relevant data from the tension sensor 6. An electric push rod is provided on the column 2, and the movable end of the electric push rod is fixedly installed with the mounting bracket 5, which in turn drives the mounting bracket 5 to move. The clamp 302 has two sets of shapes, and the grooves 401 of the two sets of clamps 302 are at horizontal and vertical angles respectively, which facilitates the adjustment and fixing of different wire harnesses. A controller is provided on the surface of the body 1 to control the use of electrical components on the surface of the body 1.

[0020] In this invention, during use, both ends of the wire harness are wound around the arc surface of the winding cylinder 304. The threaded pin 305 is rotated to fix the ends of the wire harness with the clamping ring 306, thereby ensuring the stability of the wire harness fixation. Next, the threaded rod 301 is adjusted to clamp the wire harness with the clamping plate 302, which facilitates subsequent tensile testing, ensures the stability of the wire harness positioning and fixation, and reduces breakage caused by clamping damage to the arc surface of the wire harness.

[0021] Furthermore, the groove 401 facilitates vertical positioning of the wire harness, and the protrusion 402 further fixes the arc surface of the wire harness, thereby making the wire harness tension data more accurate. The electric push rod starts and drives the mounting bracket 5 to move, and the tension sensor 6 transmits the data to an externally connected computer for data storage.

Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
