Description

TECHNICAL FIELD

[0001] The application relates to the technical field of harness processing, in particular to a wire harness unwinding protection cylinder. BACKGROUND

[0002] In the process of automobile wire harness processing, a downline machine is generally used for unwinding. In the conventional production process of a factory, a winding drum of a wire harness is placed on the ground, and a downline machine is used to pull the wound raw material wire harness to release the raw material wire harness. During the process of being pulled by the downline machine, the wound wire harness may swing outward, and the outwardly swinging wire harness may occupy a certain space, which may affect the normal operation of adjacent workstations, and the fast speed of the swinging wire harness may also cause injuries to workers.

[0003] In order to solve the problem of wire harness swinging, a device for preventing wire harness from swinging is disclosed in the utility model with the publication number CN 214298662 U, which uses an elastic structure to buffer the wire harness and thereby suppress the swinging of the wire harness. However, the following problems still exist in the comparative document: 1. The winding drum needs to be aligned with the center of the wire hole by pulling the bottom plate, and the alignment operation is relatively cumbersome; 2. The height of the base is fixed, and it is difficult to adapt to downline machines of different heights. If the height of the downline machine is small, it is difficult to place the device. If the height of the downline machine is high, there is still a long distance between the wire hole and the downline machine, which may still cause small-scale wire harness swinging; 3. The structure is complex, which increases the cost of enterprises. UTILITY MODEL CONTENT

[0004] Therefore, it is necessary to provide a wire harness unwinding protection cylinder, and the specific technical scheme is as follows.

[0005] A wire harness unwinding protection cylinder comprises:

The ring-shaped plate is connected to one end of the cylinder body away from the base and located on the outside of the cylinder body. A plurality of plug-in holes are arranged on the ring-shaped plate around the axis of the cylinder body.

[0008] A protection frame comprises protection rings, a connecting rod and a plug-in rod. A plurality of protection rings are coaxially arranged, and the connecting rod is connected to each protection ring in sequence. The plug-in rod is connected to the end of the connecting rod, and a positioning nut is connected to the plug-in rod. The plug-in rod is inserted into the plug-in hole, so that the plurality of protection rings are coaxially arranged with the cylinder body. The diameter of each protection ring gradually decreases in the direction away from the cylinder.

[0009] Further, a brush is installed on the annular plate, the brush is arranged around the inner ring of the annular plate, and the bristles of the brush extend towards the center of the barrel.

[0010] Further, four connecting rods are arranged around the axis of the protective ring, and the ends of each connecting rod are respectively connected with a plug-in rod which is parallel to the axis of the protective ring.

[0011] Further, the protective ring comprises a rod body and a connecting sleeve, the rod body is annular, and the two ends of the rod body are respectively connected with the connecting sleeve.

The base 1 comprises a bottom plate 11, a surrounding plate 12 and a positioning column 13. The surrounding plate 12 is mounted on the bottom plate 11 and surrounds a ring shape. The positioning column 13 is mounted on the bottom plate 11 and located in the surrounding plate 12, and the surrounding plate 12 and the positioning column 13 are coaxially arranged.

[0032] Specifically, referring to FIG. 2, the embodiment provides a wire harness pay-off protection cylinder, which comprises a base 1, a cylinder body 2 and a protection frame 3. The base 1 comprises a bottom plate 11, a surrounding plate 12 and a positioning column 13. The surrounding plate 12 is mounted on the bottom plate 11 and surrounds a ring shape. The positioning column 13 is mounted on the bottom plate 11 and located in the surrounding plate 12, and the surrounding plate 12 and the positioning column 13 are coaxially arranged. Figure 2As shown, the barrel 2 comprises a barrel body 21 and an annular plate 22. The barrel body 21 is sleeved with the surrounding plate 12, and specifically, the barrel body 21 can be sleeved inside the surrounding plate 12 or outside the surrounding plate 12. In this embodiment, the barrel body 21 is sleeved inside the surrounding plate 12, so that the barrel body 21 is coaxially arranged with the surrounding plate 12. The annular plate 22 is connected to one end of the barrel body 21 away from the base 1, and a plurality of insertion holes 23 are arranged on the annular plate 22 and around the axis of the barrel body 21.

[0033] Specifically, referring to Figure 3 As shown, the protective frame 3 comprises protective rings 31, connecting rods 32 and insertion rods 33. The plurality of protective rings 31 are coaxially arranged, and the connecting rods 32 are sequentially connected to the protective rings 31. The insertion rods 33 are connected to the ends of the connecting rods 32, and the positioning nuts 34 are connected to the insertion rods 33. The insertion rods 33 are inserted into the insertion holes 23, so that the plurality of protective rings 31 are coaxially arranged with the barrel body 21. The diameters of the protective rings 31 gradually decrease in the direction away from the barrel 2. By arranging the plurality of coaxially arranged protective rings 31 and gradually decreasing the diameters of the protective rings 31, the end protective ring 31 forms a smaller ring, and the protective frame 3 and the barrel body 21 limit the swinging of the wire harness.

[0034] In use, the drum with the wound wire harness is placed on the base plate 11, so that the positioning column 13 is inserted into the center of the drum. Then, the barrel body 21 is sleeved on the surrounding plate 12. Finally, the height of the positioning nut 34 is adjusted according to the height of the wire laying machine, the insertion rod 33 is inserted into the insertion hole 23, and the positioning nut 34 abuts against the annular plate 22. The wire harness is laid out from the top protective ring 31, and the swinging of the wire harness is limited by the barrel body 21 and the protective rings 31. The annular plate 22 is located outside the barrel body 21, and when the insertion rod 33 is inserted into the insertion hole 23, the insertion rod 33 is located outside the barrel body 21, so as to avoid interference of the insertion rod 33 with the wire harness.

[0035] The wire laying protective barrel provided in this embodiment can insert the positioning column 13 on the base 1 into the drum with the wound raw material wire harness, and sleeve the barrel 2 on the surrounding plate 12. The protective ring 31 is coaxially arranged with the barrel 2, so as to ensure the center alignment between the drum and the protective ring 31, without adjustment, and the operation is more convenient. The drum can be kept stable during the wire laying process. By adjusting the height of the positioning nut 34 on the insertion rod 33, and then inserting the insertion rod 33 into the insertion hole 23 so that the positioning nut 34 abuts against the end plate, the height of the top protective ring 31 can be adjusted, so as to adapt to wire laying machines of different heights, and to avoid the wire swinging phenomenon as much as possible. The wire laying protective barrel has simple structure, low cost and convenient use.

[0036] Specifically, referring to Figure 2As shown, the annular plate 22 is provided with a brush 24, which is arranged around the inner ring of the annular plate 22, and the bristles of the brush 24 extend towards the center of the barrel 2. By arranging the brush 24, the edge of the barrel 2 is prevented from cutting the wire bundle, and the wire bundle is prevented from being abraded.

[0037] Specifically, the protection frame 3 comprises four connecting rods 32 arranged around the axis of the protection ring 31. The ends of each connecting rod 32 are respectively connected with a plug rod 33, which is parallel to the axis of the protection ring 31.

[0038] Specifically, referring to Figure 3 As shown, the protection ring 31 comprises a rod body and a connecting sleeve 35; the rod body is annular, and the two ends of the rod body are respectively connected with the connecting sleeve 35. By disassembling the connecting sleeve 35, the wire bundle can be pulled out from the gap of the protection ring 31, that is, even if the wire bundle on the winding drum is not completely unwound, the winding shaft and the protection barrel can be separated.

[0039] Specifically, the connecting sleeve 35 is a rubber sleeve.

[0040] Specifically, continuing to refer to Figure 1 As shown, the guide 4 comprises a mounting rod 41 and a limiting ring 42; the mounting rod 41 is mounted on the wire unwinding machine, and one end of the mounting rod 41 extends towards the protection frame 3, and the end of the mounting rod 41 extending towards the protection frame 3 is connected with the limiting ring 42. By the limiting ring 42, the wire bundle can be limited again, and the phenomenon of wire bundle being thrown after leaving the protection frame 3 is further avoided.

[0041] The technical features of the above-mentioned embodiments can be combined in any way. In order to make the description simple, not all possible combinations of the technical features in the above-mentioned embodiments are described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.
