Description

TECHNICAL FIELD

[0001] The application relates to the technical field of tension detection, and particularly relates to an automobile wire harness tension detection device. BACKGROUND

[0002] During use, the automobile wire harness is subjected to extrusion and stretching due to bumps and the like caused by vehicle travel, and the wire harness is prone to damage under the action of tension, so that stable conduction cannot be guaranteed. Therefore, after automobile wire harness processing is completed, the tensile strength of the automobile wire harness needs to be detected.

[0003] A high-efficiency wire harness tension testing machine is disclosed in Chinese Patent No. CN114739795B, which is filed on April 20, 2022 and published as CN114739795B, and belongs to the field of tension testing equipment. The machine body is provided with a clamping assembly for clamping the cable of the wire harness. The clamping assembly is connected with a tension sensor for measuring the tension borne by the cable. The machine body is provided with a traction seat. The traction seat is slidably connected with a plurality of piston rods. The piston rods can move away from the clamping assembly. All the piston rods are connected with a clamping block for clamping the terminal of the cable. The traction seat is slidably connected with a control block. The control block is connected with a gas supply pipe. With the sliding of the control block, the gas supply pipe is connected with the piston rods in turn. The piston rods driven by the gas supply pipe move away from the clamping assembly. After the gas supply pipe is disconnected from the piston rods, the piston rods are in a freely sliding state. The present application improves the situation that workers frequently disassemble and assemble the cable of the wire harness from the tension testing machine.

[0004] In the technical solution, the wire harness terminal is blocked while the automobile wire harness is clamped, and then the wire harness is subjected to tensile detection. Although the automobile wire harness can be quickly switched for detection, when the automobile wire harness is relatively long, for example, the length of the reverse image connecting wire harness is generally 1.5-2 m, if the entire wire harness is subjected to tensile detection, a relatively long tensile path needs to be correspondingly arranged. In the wire harness processing process, the terminal is generally connected with the wire harness by a terminal pressing machine. In daily use, the damage point of the wire harness is generally at the connection between the terminal and the wire harness under the action of external force. Therefore, the tensile strength of the wire harness can be detected by subjecting the terminal connection part of the wire harness to tensile detection. Therefore, the technical solution cannot meet the tensile detection of the wire harness with a relatively long length, and further improvement can be made. SUMMARY

[0042] Please refer to Figures 2-4The sliding frame 300 comprises a left sliding seat 301 slidably connected to the sliding rail 200, a supporting column 302 fixedly installed on the top of the left sliding seat 301, a blocking piece 303 fixedly installed on the top end of the supporting column 302, an L-shaped pull rod 304 arranged on the outer side of the supporting column 302, a sliding groove 305 formed on the top of the right end of the L-shaped pull rod 304, the supporting column 302 penetrating through the sliding groove 305, the L-shaped pull rod 304 sliding relative to the supporting column 302 through the sliding groove 305, the connecting rod 306 slidably connected to the left end of the L-shaped pull rod 304, and two nuts 307 threadedly connected to the right half of the connecting rod 306, the vertical part of the L-shaped pull rod 304 being located between the two nuts 307, so that the vertical part of the L-shaped pull rod 304 can move between the two nuts 307, and the connecting rod 306 being threadedly connected to the tension sensor 600.

[0043] Please refer to Figures 4-5 The annular clamping piece 400 comprises a base 401, a surrounding ring 402 fixedly installed on the edge of the base 401, a plurality of fixed clamping plates 403 fixedly arranged on the top of the surrounding ring 402, a shaft sleeve 404 penetratingly fixed at the center of the base 401, a disc 405 fixedly installed on the top end of the outer wall of the shaft sleeve 404, and the shaft sleeve 404 being rotatably connected to the outer side of the supporting column 302, and the blocking piece 303 being attached to the top of the disc 405, so that the base 401 can rotate relative to the supporting column 302.

[0044] The disc 405 is rotatably connected to the outer side of the shaft sleeve 404. A plurality of movable clamping plates 407 are arranged on the circumferential surface of the disc 405, each movable clamping plate 407 being located between two adjacent fixed clamping plates 403, the movable clamping plate 407 being attached to the top of the surrounding ring 402, and the disc 405 being attached to the bottom of the disc 405, so that the disc 405 is limited and stably located on the top of the surrounding ring 402. The fixed clamping plates 403 and the movable clamping plates 407 form clamping openings, so that a plurality of clamping openings are formed on the circumferential surface of the annular clamping piece 400. When the length of the automobile wire harness is short, the right end of the wire harness is clamped by the clamping pulling member 800, the left end of the wire harness penetrates through one of the clamping openings, the disc 405 is rotated relative to the base 401, and the fixed clamping plates 403 and the movable clamping plates 407 clamp the wire harness, so that the terminals of the wire harness are simultaneously blocked by the fixed clamping plates 403 and the movable clamping plates 407. When the length of the automobile wire harness is long, the right end of the wire harness is clamped by the clamping pulling member 800, the left end of the wire harness penetrates through one of the clamping openings and then penetrates through the adjacent clamping opening, the wire harness bypasses the outer side of the circumferential surface of the annular clamping piece 400, and the terminal of the left end of the wire harness penetrates through the nearest clamping opening, and then the disc 405 is rotated relative to the base 401, so that the fixed clamping plates 403 clamp the movable clamping plates 407. Thus, the excess part of the wire harness is wound on the outer side of the circumferential surface of the annular clamping piece 400, and the path length of the wire harness for stretching is reduced.

[0045] The top of the rotating disc 406 is fixedly provided with a sleeve ring 408, the sleeve ring 408 is sleeved outside the embedded disc 405, the outer edge of the top of the embedded disc 405 is provided with a first length scale 409, and the inner edge of the top of the sleeve ring 408 is provided with a second length scale 410. When the movable clamping plate 407 is attached to the fixed clamping plate 403 on the right side thereof, the first length scale 409 is aligned with the second length scale 410. After the automobile wire harness is placed between the movable clamping plate 407 and the fixed clamping plate 403 on the right side thereof, the rotating disc 406 is pushed to rotate relative to the base 401, the fixed clamping plate 403 and the movable clamping plate 407 are clamped, and the length of the offset part of the first length scale 409 and the second length scale 410 indicates the diameter of the wire harness. The automobile wire harness can pass through the plurality of clamping openings, and the plurality of fixed clamping plates 403 and movable clamping plates 407 simultaneously clamp a plurality of parts of the wire harness. If the wire harness is uniform, the plurality of fixed clamping plates 403 and movable clamping plates 407 can simultaneously clamp the surface of the wire harness. If the wire harness is not uniform, the fixed clamping plate 403 and the movable clamping plate 407 can only clamp the thicker part of the wire harness, and the fixed clamping plate 403 and the movable clamping plate 407 can have a gap at the thinner part of the wire harness, so that whether the wire harness is uniform can be determined.

[0046] Please refer to Figure 6 and Figure 10 The rotating limiting piece 700 is arranged between the rotating disc 406 and the enclosing ring 402 and is used for inhibiting the rotating disc 406 from rotating relative to the enclosing ring 402.

The rotating limiting piece 700 comprises guide rails 701 fixedly arranged on the bottom of the rotating disc 406, and a driving ring 702 rotatably connected to the bottom of the rotating disc 406.

Thus, when the guide rail 701 rotates, the driving ring 702 is extruded against the sliding column 705 at the side wall of the inclined groove 704, so as to drive the sliding block 703 to slide along the guide rail 701.

[0048] The horizontal rod 706 is slidably connected through the side of the sliding block 703, the friction plate 707 is fixedly arranged at one end of the horizontal rod 706 close to the side wall of the enclosing ring 402, and the spring 708 is fixedly arranged between the sliding block 703 and the friction plate 707. The elasticity of the spring 708 enables the friction plate 707 to be attached to the side wall of the enclosing ring 402. The friction between the friction plate 707 and the enclosing ring 402 inhibits the rotating disc 406 from rotating relative to the enclosing ring 402.

[0049] The distance between the slider 703 and the friction plate 707 is adjusted by sliding the slider 703 along the guide rail 701, thereby adjusting the pressure exerted by the spring 708 on the friction plate 707, and further adjusting the friction between the friction plate 707 and the surrounding ring 402. The threaded column 709 is fixedly installed on the top of the driving ring 702, the arc-shaped slot 710 is formed on the surface of the turntable 406, the threaded column 709 passes through the arc-shaped slot 710, and the threaded sleeve 711 is threadedly connected to the top end of the threaded column 709. By holding the threaded sleeve 711 and pushing the threaded column 709 and the driving ring 702 to rotate, the pressure of the spring 708 on the friction plate 707 is adjusted. By screwing the threaded sleeve 711, the threaded sleeve 711 is pressed against the surface of the turntable 406, the position of the driving ring 702 is fixed, and the pressure exerted by the spring 708 on the friction plate 707 remains stable.

When the two clamping blocks 808 are close to each other, the two rows of clamping pieces 815 clamp and fix the wire harness through the inclined surface, and prevent the wire harness from being separated from the clamping pieces 815. Through the elasticity of the springs 816, the clamping pieces 815 prevent the wire harness from being crushed.

[0057] In use, one end of the automobile wire harness is placed between the two clamping blocks 808, and the terminal at the end is placed on the right side of the two clamping blocks 808, the adjusting screw 811 is screwed, the two clamping blocks 808 are driven to approach each other, the left supporting arm 812 and the right supporting arm 813 slide in opposite directions, and the two rows of clamping pieces 815 clamp the wire harness, and the inclined surface of the clamping pieces 815 is pressed on the surface of the wire harness to prevent the wire harness from being separated;

[0058] The other end of the automobile wire harness is then passed through one of the clamping openings, so that the terminal is placed inside the annular clamping piece 400; the rotating disc 406 is then pushed to rotate relative to the base 401, so that the fixed clamping plate 403 and the movable clamping plate 407 clamp and fix the wire harness;

[0059] When the length of the automobile wire harness is relatively long, the terminal of the automobile wire harness is first passed through one clamping opening, then passed out from the adjacent clamping opening, and then passed around the outside of the annular clamping piece 400, and then the terminal is passed into the annular clamping piece 400 from the nearest clamping opening; the rotating disc 406 is then pushed to rotate relative to the base 401, so that the fixed clamping plate 403 and the movable clamping plate 407 clamp and fix the wire harness;

[0060] When the rotating disc 406 rotates relative to the base 401, the driving gear 505 rolls on the annular gear 512, thus rotating the threaded rod 504 in the cover 502, moving the push plate 506 upward or downward, cooperating with the guiding action of the sliding bead 508 and the V-shaped slot 509, moving the two insertion rods 507 in the vertical direction while moving the two insertion rods 507 in opposite directions, thus moving the two L-shaped blocking rods 510 in opposite directions, the horizontal part of the L-shaped blocking rod 510 passing out of the avoiding port 503 and inserting into the clamping port, blocking the wire harness;

[0061] Finally, the output end of the air cylinder 900 is elongated, driving the clamping pulling member 800 to move to the right, the sliding frame 300 and the annular clamping member 400 move to the right by a distance, the supporting column 302 is attached to the right side wall of the sliding groove 305, the L-shaped pulling rod 304 is attached to the nut 307 at the right end of the connecting rod 306, thus the annular clamping member 400 stops moving to the right; the clamping pulling member 800 continues to move to the right, tightening the wire harness and applying tension to the wire harness, and the tension sensor 600 detects the tension applied to the wire harness.

[0062] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
