Description

Technical Field

[0001] The present invention relates to the field of assembly devices, and particularly to a pipe-passing assembly device for automotive production line harnesses. Background Art

[0002] The pipe-passing assembly device for automotive production line harnesses is an assembly instrument that passes the harness into the sleeve during automotive production. A large number of harnesses are used during automotive production. Therefore, the assembly device quickly performs pipe-passing assembly on the automotive harnesses, which is a commonly used device in automotive production;

[0003] Chinese Patent with the publication number "CN111037258A" discloses "a pipe-passing assembly device for automotive production line harnesses, including a mounting frame, a fixed sleeve, a fixed arc plate, a movable arc plate, a compression spring, etc.; a fixed sleeve is fixedly connected in the middle of the mounting frame, and a driving mechanism is arranged in the fixed sleeve". Although it can achieve the effects of "eliminating the need for manual passing of the harness through the pipe sleeve, with simple operation and high work efficiency", when the device is in use, for a single harness pipe-passing, the harness and the sleeve need to be separately arranged in sequence, and then a single pipe-passing assembly is carried out. It is impossible to centrally and quickly arrange the harness and the sleeve, nor can multiple harnesses be pipe-passed at one time. Therefore, the operation process is complex, reducing the assembly efficiency. Moreover, after the sleeve is arranged, due to different sleeve sizes, it may not be firmly positioned. After the harness is passed into the sleeve, displacement may occur, and it is easy to have the problem of incomplete pipe-passing. After the harness pipe-passing is completed, the firm connection of the clamp to the harness also causes trouble in removing the harness, making it inconvenient to remove and collect the harness for use after pipe-passing assembly. Summary of the Invention

[0004] The main purpose of the present invention is to provide a pipe-passing assembly device for automotive production line harnesses, which can effectively solve the technical problems proposed in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

A placement frame is fixedly installed at the upper end of the transmission mounting plate. A limit adjustment structure is fixedly installed at the upper end of the placement frame. A first rack is arranged at the front end of the limit adjustment structure. A first limit bracket is welded to the front end of the first rack. A second rack is arranged at the rear end of the limit adjustment structure. A second limit bracket is welded to the rear end of the second rack. A placement plate is fixedly installed at the rear end of the second limit bracket. A stretching block is placed on the upper end of the placement plate. A shaft rod seat is fixedly installed at the rear end of the stretching block. A torsion spring shaft rod movably penetrates through the inside of the shaft rod seat. Two merging clamping rings are movably installed outside the torsion spring shaft rod. An assembly pull rod is movably installed at the rear end of the stretching block. An assembly pull ring is fixedly installed at the rear end of the assembly pull rod.

[0007] As a further scheme of the present invention, the hydraulic assembly structure includes a hydraulic driving cylinder, a stretching connecting rod, a stretching mounting block, a docking cross bar and a docking hook. The hydraulic driving cylinder is fixedly installed at the front end of the first mounting baffle. The stretching connecting rod is fixedly installed at the front end of the piston rod of the hydraulic driving cylinder. The stretching mounting block is fixedly installed at the upper end of the stretching connecting rod. The docking cross bar is movably installed on the top of the stretching mounting block. A plurality of docking hooks are welded outside the docking cross bar.

[0008] As a further scheme of the present invention, the stretching connecting rod is arranged in an L shape. The docking cross bar penetrates through the stretching mounting block. The docking cross bar is located behind a plurality of assembly pull rings. The docking hook is inserted into the assembly pull ring for mating connection.

[0009] As a further scheme of the present invention, a driving motor is fixedly installed at the front end of the first mounting baffle. The driving motor is located on one side of the hydraulic driving cylinder. The rotating shaft of the driving motor penetrates through the first mounting baffle and is fixedly connected to the driving gear disc on one side.

[0010] As a further scheme of the present invention, the bottom of the placement frame is inserted into the insertion fixing groove for mating connection. A sleeve is placed inside the placement frame. The sleeve is placed above the transmission mounting plate. The first limit bracket and the second limit bracket are respectively attached to the front end and the rear end of the sleeve.

[0011] As a further solution of the present invention, the limit adjustment structure includes an adjustment top cover, an adjustment knob, a positioning frame and an adjustment gear. The adjustment top cover is fixedly installed at the upper end of the placement frame. The adjustment knob is movably installed at the upper end of the adjustment top cover. The positioning frame is fixedly inserted into the upper end of the adjustment knob. The adjustment gear is movably installed inside the adjustment top cover.

[0012] As a further solution of the present invention, the lower end of the adjustment knob penetrates into the adjustment top cover and is fixedly connected to the adjustment gear. Both sides of the positioning frame are inserted into the upper end inside the adjustment top cover. The first rack and the second rack are both inserted into the adjustment top cover and meshed with the adjustment gear.

[0013] As a further solution of the present invention, the stretching block is located in front of the sleeve, and the assembly pull rod passes through the sleeve.

[0014] As a further solution of the present invention, the combined clamping rings are arranged in a semi-elliptical shape, and the upper and lower combined clamping rings are symmetrically arranged around the center of the torsion spring shaft rod.

[0015] As a further solution of the present invention, a separation pulling ring is sleeved outside the stretching block. Two separation ropes are fixedly installed at the rear end of the separation pulling ring. The separation ropes penetrate forward through the stretching block and are movably connected to the top of the combined clamping rings.

[0016] Compared with the prior art, the present invention has the following beneficial effects: When positioning the sleeve using the placement frame, the stretching block for fixing the wire harness is placed at the same time and then the wire harness is quickly connected. The assembly pull rod is sleeved outside the docking hook, and then the docking cross bar and the docking hook are pushed forward by the operation of the hydraulic drive cylinder. As a result, the stretching block moves backward and passes through the sleeve, enabling the wire harness to penetrate into the sleeve to complete the pipe-passing assembly. Multiple docking hooks can penetrate multiple wire harnesses into the sleeve to complete the pipe-passing assembly at one time, realizing the quick placement and fixing of the wire harness and the sleeve, and simultaneously performing the pipe-passing assembly of multiple wire harnesses, making the pipe-passing assembly of the wire harness more convenient and labor-saving, and also improving the efficiency of the pipe-passing assembly;

[0017] When the placement frame positions the sleeve, the first limit frame and the second limit frame are simultaneously respectively in contact with the front end and the rear end of the sleeve, so as to achieve the effect of positioning the sleeve in the front and rear directions, prevent the wire harness from generating displacement when penetrating into the sleeve, and the distance between the first limit frame and the second limit frame can also be adjusted according to the length of the sleeve to position sleeves of different lengths, further facilitating the pipe-passing assembly of sleeves of different lengths;

[0018] After the wire harness penetrates into the sleeve to complete the pipe-passing assembly, pull the separation pulling ring forward. The separation pulling ring then drives the combined clamping rings to be pulled forward through the separation ropes, so as to quickly separate the two combined clamping rings to untie the wire harness. After removing the placement frame, the wire harness and the sleeve after the pipe-passing assembly can be quickly removed, which is more convenient for the removal and collection of the wire harness after the pipe-passing assembly.

[0035] As a further solution of the present invention, the lower end of the adjustment knob 18 penetrates into the adjustment top cover 17 and is fixedly connected to the adjustment gear 20. Both sides of the positioning frame 19 are inserted into the upper end inside the adjustment top cover 17. The first rack 21 and the second rack 23 are both inserted into the adjustment top cover 17 and are in meshing connection with the adjustment gear 20. When the adjustment knob 18 is rotated, the positioning frame 19 is pulled out. After the adjustment gear 20 and the adjustment knob 18 rotate, the positioning frame 19 is inserted to position it.

[0036] As a further solution of the present invention, the stretching block 26 is located in front of the sleeve 15. The assembly pull rod 32 passes through the sleeve 15, and the assembly pull rod 32 has the effect of driving the stretching block 26 to pass through the sleeve 15.

[0037] As a further solution of the present invention, the combined clamping ring 29 is arranged in a semi-elliptical shape. The upper and lower combined clamping rings 29 are symmetrically arranged around the center of the torsion spring shaft rod 28, and the combined elastic force of the torsion spring shaft rod 28 is used to drive the two combined clamping rings 29 to keep shrinking.

[0038] As a further solution of the present invention, a separation pulling ring 30 is sleeved outside the stretching block 26. Two separation ropes 31 are fixedly installed at the rear end of the separation pulling ring 30.

[0039] It should be noted that the present invention is a pipe-passing assembly device for automotive production line harnesses. When in use, the first mounting baffle 1 and the second mounting baffle 2 are the main frame parts of the device. The operation of the driving motor 4 drives the driving gear disk 3 to rotate, and the driving gear disk 3 then drives the circulating chain 11 and multiple transmission mounting plates 12 to move. First, place the sleeve 15 above the transmission mounting plate 12, and at the same time insert the placement frame 14 into the insertion fixing groove 13 to position the sleeve 15. Then, pass the assembly pull rod 32 through the sleeve 15, place the stretching block 26 above the placement plate 25 in front of the sleeve 15, insert the harness to be inserted into the sleeve 15 between the two combined clamping rings 29, and use the combined elastic force of the torsion spring shaft rod 28 on the combined clamping rings 29 to clamp the harness by the two combined clamping rings 29. Then, when the transmission mounting plate 12 moves to one side, the assembly pull ring 33 at the rear end of the assembly pull rod 32 will move to the outside of the docking hook 10, and the transmission mounting plate 12 stops moving. The operation of the hydraulic drive cylinder 6 is used to push the docking cross bar 9 and the docking hook 10 forward, thereby pulling the assembly pull ring 33 and the rear stretching block 26 backward and passing through the sleeve 15, so that the harness is inserted into the sleeve 15 to complete the pipe-passing assembly;

[0040] When the placement frame 14 positions the sleeve 15, the first limiting frame 22 and the second limiting frame 24 are simultaneously and respectively attached to the front end and the rear end of the sleeve 15 to achieve the effect of positioning the sleeve 15 in the front and rear directions, preventing displacement when the harness is inserted into the sleeve 15, and the adjusting knob 18 and the adjusting gear 20 can be rotated according to the length of the sleeve 15. The rotation of the adjusting gear 20 drives its forward and backward movement through the meshing connection with the first rack 21 and the second rack 23, thereby adjusting the distance between the first limiting frame 22 and the second limiting frame 24 to position sleeves 15 of different lengths;

[0041] After the harness is inserted into the sleeve 15 to complete the pipe-passing assembly, pull the separation pull ring 30 forward, and the separation pull ring 30 then drives the combined clamping rings 29 to be pulled forward through the separation rope 31, so as to quickly separate the two combined clamping rings 29 to untie the harness, and after removing the placement frame 14, the harness and the sleeve 15 after the pipe-passing assembly on one side can be quickly removed.
