Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire harness processing, and in particular to a wire threading mechanism. Background Technology
[0002] Existing threading mechanisms include conduit fittings and pneumatic clamps. During operation, the conduit fitting is inserted into the workpiece, and the pneumatic clamp inserts the thread into the conduit fitting by loosening and moving back and forth. Because the thread is flexible, and the pneumatic clamp needs to loosen and move to insert the thread into the conduit fitting, the pneumatic clamp can only drive the thread to move intermittently. As a result, the thread may bend during intermittent delivery, making it unable to enter the conduit fitting. Utility Model Content
[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a threading mechanism.

The first mounting base is mounted on the top of the second mounting base, and the guide tube is movable left and right and mounted on the top of the second mounting base and located on the left side of the first mounting base.
[0013] According to some embodiments of the present invention, the catheter is divided into a front half and a rear half that can move closer to or further away from each other in the front-rear direction. When the moving device moves to the left, the thread can pass through the cavity formed between the front half and the rear half. The cavity includes the contraction section and the guiding section.
[0014] According to some embodiments of the present invention, the moving device further includes a third mounting base, which is movable left and right and mounted on the right side of the fixed structure.

The guide section is movable left and right and mounted on the top of the third mounting base and located to the right of the first mounting base. The guide section can pass through the workpiece and be inserted into the retractable section.
[0015] According to some embodiments of the present invention, the first mounting base has a pneumatic gripper for fixing the workpiece.
[0016] The threading mechanism according to the embodiments of this utility model has at least the following technical effects:
[0017] 1. The moving device drives the guide tube and the workpiece to move left and right, so that the guide tube can be continuously sleeved outside the line body, avoiding the line body from entering the guide tube intermittently; and by setting a driving structure on the left side of the guide tube, the line body is straightened before entering the guide tube, avoiding the line body from bending and ensuring that the line body can continuously enter the guide tube.

[0037] Reference Figure 1As shown, the threading mechanism according to an embodiment of the present invention includes a fixed structure 100, a moving device 200, and a driving structure 300. The fixed structure 100 is used to straighten and support the thread body 101. The moving device 200 is movably mounted to the right of the fixed structure 100. The moving device 200 includes a first mounting base 210 and a guide tube 220. The first mounting base 210 is located to the right of the guide tube 220, and the first mounting base 210 mounts the workpiece 201. Figure 2 As shown, the conduit 220 can be inserted into the workpiece 201 and is located to the right of the line 101; the drive structure 300 is located to the left of the conduit 220. When the moving device 200 moves to the left, the line 101 can pass through the drive structure 300 and the conduit 220 in sequence. The drive structure 300 can apply a rightward force to a portion of the line 101 inside it so that it enters the conduit 220 in a taut state.
[0038] The moving device 200 drives the guide tube 220 and the workpiece 201 to move left and right, so that the guide tube 220 can be continuously sleeved on the outside of the line body 101, avoiding the line body 101 from intermittently entering the guide tube 220; and by providing a driving structure 300 on the left side of the guide tube 220, the line body 101 is straightened before entering the guide tube 220, avoiding the line body 101 from bending, and ensuring that the line body 101 can continuously enter the guide tube 220.
[0039] Since the thread 101 is flexible, it needs to be straightened by the fixing structure 100 before threading. After straightening, the fixing structure 100 will also keep the thread 101 straight. That is, the fixing structure 100 will also provide fixation for the thread 101 to prevent the thread 101 from bending downward and ensure that the guide tube 220 can be sleeved on the outside of the thread 101.
[0040] At work, such as Figure 1 , 2 As shown in Figure 3, the fixed structure 100 straightens the straight body 101, the guide tube 220 is inserted into the workpiece 201, the moving device 200 moves to the left, and the moving device 200 drives the guide tube 220 and the first mounting seat 210 to move to the left (that is, the guide tube 220 and the workpiece 201 move to the left together). The line 101 first passes through the driving structure 300 and then enters the guide tube 220. When the line 101 passes through the driving structure 300, a force to the right is applied to the line 101, so that the line 101 enters the guide tube 220 in a taut state.
[0041] The conduit 220 is located to the right of the line 101, which makes it easier to fit the conduit 220 onto the outside of the line 101.
[0042] In some embodiments of this utility model, the first embodiment of the drive structure 300 is as follows:
[0043] like Figure 1 , 2 As shown, the drive structure 300 is installed on the left side of the guide tube 220 and can move left and right with the guide tube 220. The drive structure 300 includes a first roller 310 and a second roller 320 spaced apart in the vertical direction. The first roller 310 and the second roller 320 together clamp the line 101.
[0044] The mobile device 200 further includes a first driving device 230, which is used to drive the first roller 310 or the second roller 320 to rotate.
[0045] The thread body 101 is straightened by the cooperation of the first roller 310 and the second roller 320, which simplifies the structure of the threading mechanism.
[0046] At work, such as Figure 2 As shown, the moving device 200 synchronously drives the driving structure 300, the guide tube 220, and the workpiece 201 to move to the left, so that the line 101 is located between the first roller 310 and the second roller 320. The first roller 310 and the second roller 320 jointly clamp the line 101. Then the first driving device 230 is activated, and the first driving device 230 drives the first roller 310 or the second roller 320 to rotate. Under the movement of the line 101 and the action of the first driving device 230, the first roller 310 rotates counterclockwise and the second roller 320 rotates clockwise. The first roller 310 and the second roller 320 provide power to keep the line 101 taut as it enters the guide tube 220.
[0047] Understandably, the first roller 310 and the second roller 320 do not completely clamp the line 101.
[0048] Specifically, the first roller 310 is positioned close to the left end of the conduit 220; the first roller 310 and the second roller 320 are directly mounted on the conduit 220; while ensuring that the first roller 310 and the second roller 320 are close to the left end of the conduit 220, the first roller 310 and the second roller 320 may not be directly mounted on the conduit 220.
[0049] When the drive structure 300 adopts the structure of the first embodiment, the fixing structure 100 may include a second fixing part and a plurality of straightening claws that can move left and right. The straightening claws straighten and support the cable body 101 through the V-shaped parts on the two claws. During operation, the second fixing part fixes the left end of the cable body 101, and the straightening claws straighten the cable body 101 from left to right. After the straightening is completed, the guide tube 220 moves to the left, and the cable body 101 gradually moves into the guide tube 220. During the movement of the guide tube 220, the straightening claws also move to the left and support the cable body 101. The straightening claws can move left and right to prevent the straightening claws from blocking the movement of the guide tube 220.
[0050] In a further embodiment of the present invention, the first roller 310 and / or the second roller 320 are movably mounted on the left side of the guide member 220 so that the positions of the first roller 310 and the second roller 320 can be adjusted, and the line 101 can be moved between the first roller 310 and the second roller 320 for clamping.
[0051] Specifically, the first roller 310 and the second roller 320 are both mounted on the left side of the guide tube 220 and can be moved up and down. For example, the first roller 310 and the second roller 320 are both adjusted in vertical position by a cylinder.
[0052] In a further embodiment of this utility model, such as Figure 1 As shown, the outer circumferential surface of the second roller 320 has an annular groove 321, and the line body 101 is located in the annular groove 321.
[0053] By providing an annular groove 321, the line 101 can be prevented from falling off the clamping of the first roller 310 and the second roller 320.
[0054] Specifically, the diameter of the line 101 is greater than or equal to the depth of the annular groove 321, ensuring that the first roller 310 and the second roller 320 can jointly clamp the line 101.
[0055] In some embodiments of this utility model, such as Figure 4 As shown,
[0056] The fixing structure 100 includes a first fixing part for fixing the left end of the cable body 101 and a cable clip 110 that can move left and right and is located to the right of the first fixing part. The cable clip 110 includes two clips 111 that are spaced apart in the front-back direction.
[0057] Second embodiment of fixed structure 100:
[0058] The drive structure 300 includes a third roller 330 and a second drive device 340. Each clamp 111 is equipped with a second drive device 340. The second drive device 340 is connected to the third roller 330. The second drive device 340 is used to drive the third roller 330 to rotate. When the two clamps 111 straighten the line 101, the two third rollers 330 clamp the line 101 together.
[0059] By employing the above-described structure, the fixed structure 100 and the drive structure 300 are combined together, resulting in a compact structure.
[0060] At work, such as Figure 4 , 5 As shown, the first fixing part fixes the left end of the thread 101. The two clamps 111 move closer to each other and from left to right to straighten the thread 101. At the same time, the two third rollers 330 clamp the thread 101 together. The second driving device 340 is activated, and the two second driving devices 340 drive the two third rollers 330 to rotate clockwise, so that the thread 101 is taut. When the two clamps 111 move to a position close to the right end of the thread 101, the moving device 200 drives the guide tube 220 to move to the left, so that the guide tube 220 is close to the two clamps 111. After being close to the two clamps 111, the guide tube 220 and the two clamps 111 move to the left together, so that the thread 101 is taut by the two third rollers 330 and enters the guide tube 220.
[0061] In a further embodiment of this utility model, such as Figure 6 As shown, the catheter 220 includes a constriction section 221 and a guide section 222. The diameter of the constriction section 221 gradually decreases from left to right, and the diameter of the guide section 222 is the same as the diameter at the right end of the constriction section 221.
[0062] By providing a contraction section 221, the right end of the line 101 can more easily enter the guide section 222.
[0063] In a further embodiment of this utility model,
[0064] like Figure 1 As shown, the first embodiment of the catheter fitting 220:
[0065] The mobile device 200 further includes a second mounting base 240, which is movable left and right and mounted on the right side of the fixed structure 100. The first mounting base 210 is mounted on the top of the second mounting base 240, and the guide tube 220 is movable left and right and mounted on the top of the second mounting base 240 and located to the left of the first mounting base 210.
[0066] That is, the shrink section 221 and the guide section 222 are an integral structure and are located to the left of the first mounting base 210 or the workpiece 201.
[0067] During operation, the shrinking section 221 and the guiding section 222 move together to the right, so that the guiding section 222 is inserted into the workpiece 201.
[0068] In a further embodiment of this utility model, such as Figure 2 , 6 As shown, the guide tube 220 is divided into a front half 223 and a rear half 224 that can move closer to or further away from each other in the front-back direction. When the moving device 200 moves to the left, the wire 101 can pass through the cavity 202 formed between the front half 223 and the rear half 224. The cavity 202 includes a contraction section 221 and a guiding section 222, so that the guide tube 220 can be opened in the front-back direction after it is removed from the workpiece 201, making it convenient to take out the workpiece 201 that has been threaded.
[0069] In a further embodiment of this utility model,
[0070] Second embodiment of catheter fitting 220:
[0071] like Figure 7 , 8 As shown in Figure 9, the moving device 200 further includes a third mounting base 250, which is movable left and right and mounted on the right side of the fixed structure 100. The first mounting base 210 is mounted on the top of the third mounting base 250. The retractable section 221 is mounted on the top of the third mounting base 250 and located to the left of the first mounting base 210. The guide section 222 is movable left and right and mounted on the top of the third mounting base 250 and located to the right of the first mounting base 210. The guide section 222 can pass through the workpiece 201 and be inserted into the retractable section 221.
[0072] That is, the shrink section 221 and the guide section 222 are designed separately. The shrink section 221 is located to the left of the workpiece 201, and the guide section 222 is located to the right of the workpiece 201.
[0073] During operation, the guide section 222 moves to the left, passes through the workpiece 201, and inserts into the retraction section 221.
[0074] In a further embodiment of this utility model, such as Figure 1 As shown, the first mounting base 210 has a pneumatic gripper 211 for fixing the workpiece 201, which facilitates the mounting and dismounting of the workpiece 201.
