Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of automobile cable processing, especially relates to an automobile cable unwinding device. BACKGROUND

[0002] The automobile cable is various types of wires such as data line, ignition line, conductor and the like used in cooperation on the automobile. In the production process, when the ignition line is produced, the cable in the roll needs to be unwound, and then processed into a semi-finished product wire of a specific length by processing equipment, and then processed into a finished product wire by measures such as cap pressing.

[0003] Therefore, in the production process, the unwinding of the cable in the roll is particularly important. In the unwinding process, firstly, the stability of unwinding needs to be maintained. Specifically, because the cable roll is relatively heavy, in the unwinding process, the traditional unwinding equipment (mostly rotary unwinding) is difficult to maintain the stability of rotary unwinding. The reason is that the cable roll is difficult to be accurately placed at the center position of the unwinding equipment through the crane below.

[0004] Secondly, in the unwinding process, the slack degree of the cable is relatively high, and the high slack degree leads to the difficulty in accurate processing in the subsequent processing equipment, such as the cutting equipment for cutting the unwound cable in sections. Because the cable is too loose, the cutting accuracy is not high.

[0005] And the existing unwinding equipment is difficult to consider the tensioning of the cable in the unwinding process, which seriously affects the accuracy and efficiency of processing.

[0006] Therefore, in the production process of the automobile cable, how to maintain the cable roll to stably unwind the cable and keep the cable tensioned is very important for improving the production efficiency and increasing the accuracy of production. INVENTION CONTENTS

[0039] Example 1

[0040] like Figures 1-4 As shown, an automotive cable unwinding device includes a cable unwinding mechanism and a cable tensioning mechanism that cooperates with the cable unwinding mechanism. During operation, the cable tensioning mechanism tensions the cable while the cable unwinds it. This method achieves both precise cable unwinding and maintaining cable tension during the unwinding process.

[0041] The specific structure of the cable-laying mechanism is as follows:

[0042] The cable-laying mechanism includes a lower fixing base structure 1. Specifically, the lower fixing base structure 1 includes an annular base portion 11, and the top of the annular base portion 11 is integrally formed with a vertically arranged annular rib 12. An annular groove is formed on the top of the annular rib 12, and a plurality of circumferentially distributed bottom support shafts 13 are rotatably connected in the annular groove (similar to the existing method, the two ends of the bottom support shafts 13 are rotatably connected in the annular groove by pins). The top of the bottom support shafts 13 protrudes from the top surface of the annular groove.

[0043] Meanwhile, the top of the lower fixed seat structure 1 is rotationally connected with an upper rotating seat structure 3. A limiting rolling structure is arranged between the lower fixed seat structure 1 and the upper rotating seat structure 3, and the upper rotating seat structure 3 is rotationally limited by the limiting rolling structure during rotation. In this way, the stability and safety of cable winding and unwinding are improved.

[0044] Specifically, the upper rotating seat structure 3 comprises an upper annular support seat 31, and a cylindrical intermediate part is integrally formed at the bottom of the upper annular support seat 31. A lower annular seat 32 is integrally formed at the bottom of the cylindrical intermediate part, and the lower annular seat 32 is supported to roll on the bottom support shaft 13.

[0045] During operation, the lower annular seat 32 is supported on the circumferentially distributed support shaft 13 during rotation of the upper rotating seat structure 3 (the cable is placed on the upper annular support seat 31 of the upper rotating seat structure 3), so that the stability of rotation and the safety of cable unwinding are improved.

[0046] In order to further improve the safety of the upper rotating seat structure 3 during cable unwinding, the above-mentioned limiting rolling structure further comprises a plurality of limiting wheel supports 2 fixedly connected to the top of the annular base part 11 (the limiting wheel supports 2 are arranged in a circumferential manner), and a limiting pressure wheel 21 is rotationally connected to the upper end of the limiting wheel support 2. The limiting pressure wheel 21 is pressed against the top of the lower annular seat 32.

[0047] During operation, when the upper rotating seat structure 3 rotates, the top of the upper annular support seat 31 is pressed by the limiting pressure wheel 21, and the limiting pressure wheel 21 rolls relative to the upper rotating seat structure 3 during rotation, and limits the upper rotating seat structure 3 in a pressing manner, so that the upper rotating seat structure 3 does not tip over or shake during rotation (the upper rotating seat structure 3 is extremely heavy after loading the cable drum).

[0048] Embodiment 2

[0049] As shown in Figures 1-4 the structure of embodiment 1, in order to realize automatic cable unwinding, the above-mentioned cylindrical intermediate part is fixedly connected with an upper connecting frame 41 (the transverse cross-sectional shape of the upper connecting frame 41 is cross-shaped), the central part of the annular base part 11 is fixedly connected with a driving motor 42, and the output shaft of the driving motor 42 is fixedly connected with the upper connecting frame 41.

[0050] Meanwhile, the central part of the upper connecting frame 41 is threadedly connected with a connecting bolt locked on the output shaft of the driving motor 42 (the tightening direction of the thread is the rotation direction of the output shaft, so that the bolt does not loosen during rotation).

[0051] Meanwhile, the bottom of the above-mentioned annular base part 11 is fixedly connected with a bottom bracket 43 (the transverse cross-sectional shape of the bottom bracket is cross-shaped), and the driving motor 42 is fixedly installed at the top of the bottom bracket 43 in a conventional manner

[0052] Embodiment 3

[0053] As Figures 1-4 shown, the embodiment is based on the structure of embodiment 2, in order to realize the tensioning cable process, the above-mentioned cable tensioning mechanism includes several tensioning structures, and the tensioning structure includes a tensioning press wheel with adjustable height and angle.

[0054] Specifically, the left and right side walls of the annular base part 11 are respectively welded with beam bars 5, and a pair of front and rear tensioning structures are installed between the front ends of the beam bars 5.

[0055] Similarly, the rear ends of the beam bars 5 are installed with tensioning structures 6 (according to the cable unwinding direction, the front and rear tensioning structures 6 are selected).

[0056] The tensioning structure 6 further includes an adjusting frame, and the tensioning press wheel is installed on the adjusting frame.

[0057] Specifically, the adjusting frame includes a vertical rod body 61 fixedly connected at the top position of the beam bar 5, and a horizontal rod 62 with adjustable height is slidingly connected between the vertical rod bodies 61; the specific height adjustment mode is that the two ends of the horizontal rod 62 are respectively fixedly connected with sliding end seats, the sliding end seats are slidingly connected with the vertical rod bodies 61, and a pair of adjusting nuts are threadedly connected on the vertical rod bodies 61 and positioned at the top and bottom positions of the sliding end seats.

[0058] After loosening the adjusting nuts, the height of the horizontal rod 62 is adjusted.

[0059] At the same time, the tensioning press wheel includes a wheel seat 63 and a press wheel 631 rotatingly connected on the wheel seat 63; the wheel seat 63 is slidingly connected with the horizontal rod 62, and a pair of nuts 621 are threadedly connected on the horizontal rod 62 and positioned at both sides of the wheel seat 63.

[0060] During work, the angle of the adjusting wheel seat 63 is adjusted by loosening the nuts 621, and after the angle is adjusted, the pressing force of the press wheel 631 on the cable increases (and then the nuts 621 are pressed again to position the tensioning press wheel 631), and in the same way, the tensioning force is further adjusted by adjusting the height of the horizontal rod 62.

[0061] Under the tensioning of the pair of tensioning press wheels, the cable unwinding process has high stability, and the subsequent processing equipment can be accurately processed.

[0062] In actual work process, a ring-shaped wheel groove is formed on the contour of the press wheel 631, and the cable is limited in the wheel groove, so as to further increase the stability of the cable unwinding process.

[0063] Of course, the above description is not a limitation of the utility model, the utility model is also not limited to the above examples, the changes, modifications, additions or replacements made by the person skilled in the art within the essential scope of the utility model should also belong to the protection scope of the utility model.
