Description

Technical Field

[0001] The utility model belongs to the technical field of cable detection, and in particular relates to a cable clamping device. Background Art

[0002] Cable clamping equipment plays a vital role in the production and processing of cables and wires. While existing cable clamping equipment can secure cables, some processing and inspection processes require not only fixed cables but also axial rotation for more complex operations. For example, cable rotation is essential in processes such as surface inspection, coating, and twisting. However, most existing clamping equipment is complex and cumbersome to operate, making it difficult to meet the requirements for flexible cable clamping and rotation during production.

[0003] Furthermore, when using pneumatic cylinders to drive the jaws, conventional cable clamping devices can easily cause the air tube to become tangled during rotation, reducing the stability and service life of the equipment and impacting production efficiency. Furthermore, existing clamping devices often struggle to maintain the axial center position of the cable when clamping it, affecting clamping precision and reducing the accuracy of subsequent processing and testing.

[0004] Therefore, how to design a cable clamping device with a simple structure, easy operation, the ability to drive the cable to rotate, and the ability to improve clamping accuracy and stability has become an urgent problem to be solved in the technical field. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a cable clamping device with a simple structure. While clamping the cable, it can also drive the cable to rotate. It can adapt to various processing and testing procedures of the cable and is suitable for promotion and application.

[0006] The technical solutions provided by this utility model are as follows:

[0007] A cable clamping device includes a machine base and a cross roller bearing connected to one side of the machine base. The outer ring of the cross roller bearing is fixed to the machine base. One side of the inner ring of the cross roller bearing is connected to a synchronous pulley and the other side is connected to a rotating shaft. The rotating shaft is an annular structure. The synchronous pulley is driven by a motor. A connecting plate is provided on the side of the rotating shaft away from the synchronous pulley.

[0008] The connecting plate is provided with a symmetrical first clamp and a second clamp. The first clamp is driven by the first telescopic cylinder, and the second clamp is driven by the second telescopic cylinder. The first clamp and the second clamp move relative to each other to hold the cable tightly and drive the cable to rotate along its axis.

[0009] In some embodiments, the first telescopic cylinder and the second telescopic cylinder are symmetrically fixed on both sides of the connecting plate, the output end of the first telescopic cylinder is provided with a first push plate, the first clamping claw is fixed on the first push plate, and the output end of the second telescopic cylinder is provided with a second push plate, the second clamping claw is fixed on the second push plate.

[0010] In some embodiments, two guide pillars are provided on the connecting plate, and the first push plate and the second push plate are slidably connected to the guide pillars.

[0011] In some embodiments, a gear is provided on the guide column, a first rack is provided on both sides of the first push plate, and a second rack is provided on both sides of the second push plate, and the first rack and the second rack are engaged with the gear at the same time.

[0012] In some embodiments, the first clamping jaw and the second clamping jaw are both in the shape of comb teeth, and the comb teeth on the first clamping jaw and the second clamping jaw are staggered.

[0025] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention. Example

[0026] like Figure 1-4 The figure shows a cable clamping device comprising a base 1 and a cross roller bearing 2. The outer ring of the cross roller bearing 2 is fixed to the base 1. The inner ring of the cross roller bearing 2 is connected to a synchronous pulley 3 on one side and to a rotating shaft 4 on the other side. A connecting plate 5 is provided on the side of the rotating shaft 4 away from the synchronous pulley 3. The synchronous pulley 3 is driven by a motor 17. The output end of the motor 17 is connected to a small synchronous pulley 20. The small synchronous pulley 20 and the synchronous pulley 3 are driven by a synchronous belt 19, thereby driving the rotating shaft 4 and the connecting plate 5 to rotate.

[0027] A symmetrical first clamping jaw 6 and a second clamping jaw 8 are provided on the connecting plate 5. The first clamping jaw 6 is driven by a first telescopic cylinder 7, and the second clamping jaw 8 is driven by a second telescopic cylinder 9. The rotating shaft 4 is an annular structure, and the cable passes through the rotating shaft 4. At the same time, the first clamping jaw 6 and the second clamping jaw 8 move relative to each other to clamp the cable and can drive the cable to rotate along its axial direction.

[0028] In this embodiment, the first telescopic cylinder 7 and the second telescopic cylinder 9 are both air cylinders, and a gas distribution ring 16 is provided on the rotating shaft 4. The air outlet 18 of the gas distribution ring 16 is set on the connecting plate 5 and connected to the first telescopic cylinder 7 and the second telescopic cylinder 9 through an air pipe.

[0029] Since the connecting plate 5 needs to rotate during use, the air outlet 18 of the cylinder is connected to the connecting plate 5 through the setting of the air distribution ring 16. The air outlet 18 can be directly connected to the first telescopic cylinder 7 or the second telescopic cylinder 9 through an air pipe. During the rotation process, the air pipe will not get tangled, thereby improving the stability of the device. Example

[0030] This embodiment is formed on the basis of the embodiment 1, and by providing the structure of the first clamping jaw 6 and the second clamping jaw 8 and their driving mechanism, the stability, accuracy and versatility of cable clamping are improved. Specifically:

[0031] The first telescopic cylinder 7 and the second telescopic cylinder 9 are symmetrically fixed on both sides of the connecting plate 5. The output end of the first telescopic cylinder 7 is provided with a first push plate 10, and the first clamping jaw 6 is fixed to the first push plate 10. The output end of the second telescopic cylinder 9 is provided with a second push plate 11, and the second clamping jaw 8 is fixed to the second push plate 11. Two guide posts 12 are provided on the connecting plate 5, and the first push plate 10 and the second push plate 11 are slidably connected to the guide posts 12.

[0032] The first clamping jaw 6 and the second clamping jaw 8 are fixed on the first push plate 10 and the second push plate 11. At the same time, the first push plate 10 and the second push plate 11 are guided by the guide column 12, which ensures that the relative movement of the first clamping jaw 6 and the second clamping jaw 8 is in the same straight line, thereby improving the stability of the clamping.

[0033] A gear 13 is fixed to the guide column 12 through a gear seat. First racks 14 are provided on both sides of the first push plate 10, and second racks 15 are provided on both sides of the second push plate 11. The first rack 14 and the second rack 15 are engaged with the gear 13 at the same time.

[0034] The gear 13 is engaged with the first rack 14 and the second rack 15 at the same time. When the first telescopic cylinder 7 or the second telescopic cylinder 9 pushes the first push plate 10 or the second push plate 11 to move, the cooperation of the rack and the gear 13 can ensure that the first push plates 10 and the second push plates 11 on both sides can move synchronously, ensuring that the first clamping jaw 6 and the second clamping jaw 8 can clamp the cable at the same time, ensuring that the cable is at the center of the axis when being clamped, and improving the accuracy of clamping.

[0035] Furthermore, the first clamping jaw 6 and the second clamping jaw 8 are both in the shape of comb teeth, and their cross-sections are V-shaped. The comb teeth on the first clamping jaw 6 and the second clamping jaw 8 are staggered.

[0036] The staggered comb-tooth structure allows the comb teeth on the first clamping jaw 6 and the second clamping jaw 8 to interlock when clamping thinner cables, ensuring that the surfaces of the first clamping jaw 6 and the second clamping jaw 8 can fit the surface of the thin cable; when clamping thicker cables, the comb teeth do not need to interlock, and the cable is clamped only by the V-shaped surfaces of the first clamping jaw 6 and the second clamping jaw 8, thereby improving the versatility of cable clamping.
