DETAILED DESCRIPTION

[0032] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0033] The present application will be further described below with reference to the embodiments.

[0034] Embodiment: a terminal machine wire harness traction device, referring to the drawings Figure 1 - the drawings Figure 7 , comprising,

[0035] The mounting plate 110, the compression wheels 120 symmetrically arranged on the upper and lower sides of the mounting plate 110, the two wire harness compression motors 130 adapted to be mounted on the other side of the mounting plate 110 and used in cooperation with the compression wheels 120, the wire harness traction motor 140 adapted to be mounted on the outer surface of the mounting plate 110 and used to control the distance between the two sets of compression wheels 120 and the wire harness compression motor 130, and the belt tensioning piece 150 arranged outside the wire harness compression motor 130;

[0036] It should be noted that the mounting plate 110 is used to integrate and fix the two sets of symmetrically arranged compression wheels 120, the wire harness compression motor 130, the wire harness traction motor 140 and the belt tensioning piece 150, to ensure the coaxiality and position accuracy of each component, the wire harness compression motor 130 can drive the compression wheels 120 to move up and down, so as to adjust the clamping force according to the thickness of the wire harness, the wire harness traction motor 140 can drive the compression wheels 120 to rotate through the belt transmission, and the belt tensioning piece 150 is used to adjust the belt tension to avoid transmission slip.

[0037] The two groups of compression wheels 120, wire harness compression motors 130, wire harness traction motors 140 and belt tensioners 150 are respectively arranged on the left and right sides of the mounting plate 110.

[0038] The positioning mechanism 200 comprises a guide assembly 210 capable of preventing various specifications of wire harnesses from falling off from the compression wheels 120 during traction, a transmission assembly 220 capable of generating a pushing force when the guide assembly 210 adjusts the opening size, and a deviation rectifying assembly 230 capable of automatically rectifying the deviation of the wire harnesses with the pushing force of the transmission assembly 220;

[0039] The guide assembly 210, the transmission assembly 220 and the deviation rectifying assembly 230 are each provided with two groups and are respectively arranged at the entrances of the two groups of compression wheels 120;

[0040] The guide assembly 210 comprises a fixed column 211 fixedly connected to the outer surface of the mounting plate 110, a rotating disc 212 rotatably sleeved on both sides of the fixed column 211, a fixed block 213 fixedly arranged in a circumferential array on the outer surface of the rotating disc 212, and a limiting rod 214 fixedly installed on the inner surface of the fixed block 213 and used for limiting the wire harness.

[0041] Specifically, the guide assembly 210 further comprises a plurality of movable sleeves 215 rotatably connected to the outer end surface of the fixed column 211 and used in cooperation with the limiting rod 214, a worm 216 rotatably connected to the outer surface of the mounting plate 110, and a worm wheel 217 engaged with the outer surface of the worm 216 and used in cooperation with the rotating disc 212.

[0042] It should be noted that after the wire harness passes through the centers of the plurality of limiting rods 214, the movement range of the wire harness can be preliminarily limited by the limiting rods 214. At this time, the worm 216 is rotated, the rotating disc 212 can be driven to rotate around the fixed column 211 through the worm wheel 217. When the rotating disc 212 rotates, the plurality of fixed blocks 213 and the limiting rods 214 can be simultaneously driven to move in a circumferential direction, and the limiting rods 214 are driven to slide along the inner surface of the movable sleeve 215. By changing the surrounding diameter of the limiting rods 214, various specifications of wire harnesses can be adapted. The movable sleeve 215 not only provides sliding guidance for the limiting rods 214, but also ensures that the plurality of limiting rods 214 always form a concentric circular constraint space, thereby cutting off the path of the wire harness falling off from the gap between the compression wheels 120.

[0043] Further, the outer surface of the limiting rod 214 is in sliding contact with the inner surface of the movable sleeve 215, and the worm wheel 217 is fixedly connected to the outer surface of the rotating disc 212;

[0044] When the wire harness is threaded through the center of the plurality of limiting rods 214, and the worm 216 is rotated to drive the worm gear 217 to rotate, the rotating disc 212 can drive the plurality of fixed blocks 213 and the limiting rods 214 to perform synchronous circular motion, so as to drive the plurality of limiting rods 214 to simultaneously slide along the inner surface of the corresponding movable sleeve 215, thereby limiting the wire harness.

[0045] Preferably, the transmission assembly 220 comprises a first bevel gear 221 fixedly sleeved on the outer end surface of the worm 216, a second bevel gear 222 engaged with the outer surface of the first bevel gear 221, a connecting column 223 fixedly connected to the inner surface of the second bevel gear 222, and a cam 224 fixedly sleeved on the other end of the connecting column 223.

[0046] It should be further noted that when the worm 216 rotates, the first bevel gear 221 can drive the second bevel gear 222 to rotate synchronously, and then the second bevel gear 222 can drive the connecting column 223 and the cam 224 to rotate. Through the eccentric structure of the cam 224, a periodic thrust is generated during rotation, and the thrust size corresponds to the rotation angle of the worm 216.

[0047] It should be noted that bearings are installed at the connecting position of the connecting column 223 and the mounting plate 110 for synchronous rotation.

[0048] When the worm 216 rotates, the fixed column 211 can drive the second bevel gear 222, the connecting column 223, and the cam 224 to rotate synchronously, so that the cam 224 generates a thrust.

[0049] Furthermore, the deviation rectifying assembly 230 comprises a fixed seat 231 fixedly connected to the outer surface of the mounting plate 110, a stress block 232 arranged on the outer side of the fixed seat 231 and matched with the cam 224, a driven column 233 fixedly connected to the outer surface of the stress block 232, and a connecting block 234 fixedly connected to the penetrating end of the driven column 233.

[0050] Specifically, the deviation rectifying assembly 230 further comprises a hinged block 235 hinged on both sides of the connecting block 234, a swing arm 236 hinged on the other end of the hinged block 235, a pressing block 237 fixedly connected to the outer end surface of the swing arm 236 and used for rectifying the wire harness, a fixed rod 238 fixedly connected to the outer surface of the fixed seat 231 and used for supporting the swing arm 236, and a spring 239 sleeved on the outer side of the driven column 233.

[0051] It needs to be explained that when the cam 224 rotates, the thrust can be applied to the force block 232, so that the force block 232 compresses the spring 239, and at the same time, drives the driven column 233 to slide along the inner surface of the fixed seat 231, and then drives the connecting block 234 to move through the driven column 233, and the connecting block 234 pulls the two side swing arms 236 through the hinged block 235, and the fixed rod 238 is used as the fulcrum to rotate, and then the swing arm 236 drives the pressing block 237 to swing to the wire harness direction, and pushes the deviated wire harness back to the center position. Because the thrust of the cam 224 is synchronized with the adjustment of the guide assembly 210, the deviation correction range of the pressing block 237 automatically changes with the wire harness specification.

[0052] Preferably, the outer surface of the force block 232 is in sliding contact with the outer surface of the cam 224, the driven column 233 is slidably connected to the inner surface of the fixed seat 231, and the end of the swing arm 236 away from the pressing block 237 is rotatably sleeved on the outer surface of the fixed rod 238.

[0053] The spring 239 is fixedly installed on the outer surface of the fixed seat 231, and the other end thereof abuts against the force block 232.

[0054] In use,

[0055] The wire harness to be processed is passed through the centers of the plurality of limiting rods 214 to preliminarily limit the movement range of the wire harness, and then the worm 216 is rotated to drive the worm gear 217 and the rotating disc 212 to rotate around the fixed column 211, and then the rotating disc 212 drives the plurality of fixed blocks 213 and the limiting rods 214 to perform synchronous circular motion, so that the plurality of limiting rods 214 synchronously slide along the inner surfaces of the corresponding movable sleeves 215, and finally the surrounding diameters of the plurality of limiting rods 214 are changed to adapt to the current wire harness specification, and a concentric circular constraint space is formed.

[0056] At the same time, the worm 216 drives the first bevel gear 221 to rotate, the second bevel gear 222 and the connecting column 223 are synchronously rotated, and then the connecting column 223 drives the cam 224 to rotate, and through the thrust generated by the eccentric structure of the cam 224 when rotating, the force block 232 is pushed to compress the spring 239, and at the same time, the driven column 233 slides along the inner surface of the fixed seat 231, the connecting block 234 moves synchronously with the driven column 233, and the swing arm 236 is pulled through the hinged block 235, and the fixed rod 238 is used as the fulcrum to rotate, and finally the pressing block 237 swings to the wire harness to complete the deviation correction.

[0057] Finally, the wire harness pressing motor 130 is started to drive the pressing wheel 120 to clamp the wire harness, the control wire harness traction motor 140 drives the pressing wheel 120 to rotate through the belt transmission, and the belt tensioning piece 150 adjusts the tension to prevent slipping, so that the wire harness is stably conveyed under the traction of the pressing wheel 120.

[0058] In summary, by setting the positioning mechanism 200, not only can the wire harness of various specifications be flexibly limited when the compression wheel 120 is conveying the wire harness at high speed, and the wire harness is prevented from falling off the gap between the compression wheel 120, but also the compression block 237 can automatically correct the offset angle of the wire harness, and the friction between the wire harness and the edge of the compression wheel 120 is avoided, so as to realize the effect of ensuring the stability of the wire harness traction process while protecting the integrity of the outer insulating skin of the wire harness.

[0059] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced by equivalents; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present application.
