Although the present utility model is described in conjunction with its preferred specific implementation modes, these implementation modes are only illustrative and do not limit the scope of the present utility model.

[0031] As shown in the attached Figures 1-5 figure, a self - rotating automatic roughening device for the surface of a thick cable includes a cable 10, a frame 100, a front - end cable rotation module 200, an intermediate cable rotation module 300, a cable torsion release module 400, and a cable grinding module 500;

[0032] The front - end cable rotation module 200 is disposed opposite to the intermediate cable rotation module 300 and fixed to the upper part of the front end of the frame 100, and is used for clamping and rotating the front end of the cable 10;

[0033] The cable torsion release module 400 is collinear with the front - end cable rotation module 200 and the intermediate cable rotation module 300, and is located behind the intermediate cable rotation module 300, and is used for torsion release to prevent the cable 10 from being damaged due to excessive torsion;

[0034] The cable grinding module 500 is fixed to the upper part of the frame 100 and is located on one side between the front - end cable rotation module 200 and the intermediate cable rotation module 300, and is used to achieve axial grinding of the cable 10.

[0035] Specifically, the front - end cable rotation module 200 includes a first support frame 210, a first driving mechanism 220, an outer - gear hollow bearing 230, a first connecting block 240, an up - and - down movement mechanism 250, an upper clamping and positioning block 260, a lower clamping and positioning block 280, and a positioning support block 270; the first driving mechanism 220 includes a first driver 221 and a first driving gear 222. Among them, the first driver 221 is preferably a stepping motor. The outer - gear hollow bearing 230 is fixed on the first support frame 210 and meshes with the first driving gear 222 to realize the rotation of the cable 10. The up - and - down movement mechanism 250 pushes the upper clamping and positioning block 260 to cooperate with the lower clamping and positioning block 280 to realize clamping and releasing of the cable 10, and both the up - and - down movement mechanism 250 and the lower clamping and positioning block 280 are fixed on the outer - gear hollow bearing 230 through the first connecting block 240. Among them, the up - and - down movement mechanism 250 is preferably a rod - guided cylinder.

[0036] Specifically, the intermediate cable rotation module 300 includes a second support frame 310, a second driving mechanism 320, an outer gear hollow bearing II 330, a second connecting block 340, an up-and-down movement mechanism II 350, an upper pressing and positioning block II 360, a lower pressing and positioning block II 380, and a positioning support block II 370; the second driving mechanism 320 includes a second driver 321 and a second driving gear 322. Among them, the second driver 321 is preferably a stepping motor. The outer gear hollow bearing II 330 is fixed on the second support frame 310 and meshes with the second driving gear 322 to realize the rotation of the cable 10. The up-and-down movement mechanism II 350 pushes the upper pressing and positioning block II 360 to cooperate with the lower pressing and positioning block II 380 to realize the pressing and releasing of the cable 10. Both the up-and-down movement mechanism II 350 and the lower pressing and positioning block II 380 are fixed on the outer gear hollow bearing II 330 through the second connecting block 340. Among them, the up-and-down movement mechanism II 350 is preferably a guide rod cylinder.

[0037] Specifically, the cable torsion release module 400 includes a third support frame 410, a lateral movement mechanism 420, a fixing plate 430, an up-and-down movement mechanism III 450, an upper pressing and positioning block III 460, and a lower pressing and positioning block III 440. The up-and-down movement mechanism III 450, the upper pressing and positioning block III 460, and the lower pressing and positioning block III 440 are installed on the lateral movement mechanism 420 through the fixing plate 430; the up-and-down movement mechanism III 450 pushes the upper pressing and positioning block III 460 to cooperate with the lower pressing and positioning block III 440 to realize the pressing of the rear end of the cable 10. Among them, the up-and-down movement mechanism III 450 is preferably a guide rod cylinder.

[0038] Specifically, the lateral movement mechanism 420 includes a guiding mechanism 421 and a third driving mechanism 422. The guiding mechanism 421 and the third driving mechanism 422 are both installed on the third support frame 410. Among them, the guiding mechanism 421 is preferably a guide rail slider mechanism, and the third driving mechanism 422 is preferably a powered single-axis module.

[0039] During the process that the first driving mechanism 220 of the front-end cable rotation module 200 and the second driving mechanism 320 of the intermediate cable rotation module 300 drive the cable 10 to rotate a certain angle, the cable torsion release module 400 drives the cable 10 to move forward. However, the middle part of the cable 10 is clamped and cannot move laterally. Therefore, a circular ring will be formed between the intermediate cable rotation module 300 and the cable torsion release module 400 for the cable 10, and this circular ring is used to release most of the torsion.

[0040] Specifically, the cable grinding module 500 includes a fourth support frame 510, a transverse movement mechanism 520, a lifting mechanism 530, a pushing and pulling mechanism 540, and a grinding mechanism 550. The transverse movement mechanism 520 is fixed on the frame 100 through the fourth support frame 510 and provides axial movement power for the axial grinding of the cable 10. The transverse movement mechanism 520 includes a fourth driving mechanism 521 and a second guiding mechanism 522. The grinding mechanism 550 includes a grinding main shaft 551 and a grinding head 552. Among them, the second guiding mechanism 522 is preferably a slider rail mechanism, the fourth driving mechanism 521 is preferably a gear rack and motor mechanism, and the grinding main shaft 551 is preferably an electric main shaft capable of adjusting the grinding speed.

[0041] Specifically, the lifting mechanism 530 is fixed on the transverse movement mechanism 520, and the pushing and pulling mechanism 540 is fixed on the lifting mechanism 530. Among them, the lifting mechanism 530 and the pushing and pulling mechanism 540 are preferably a guide rod cylinder. When the grinding head 552 works, the lifting mechanism 530 and the pushing and pulling mechanism 540 move towards the cable 10, making the grinding head 552 contact the cable 10 to complete the grinding work. When stopping working, the lifting mechanism 530 and the pushing and pulling mechanism 540 move away from the cable 10, separating the grinding head 552 from the cable 10, facilitating loading and unloading and preparing for the next grinding of the cable 10.

[0042] Specifically, a PLC control system is also installed in the roughening equipment to realize the coordinated work of the internal machinery, electricity, and sensors of the equipment, and the control operation is realized through an external electric control box and the buttons distributed on it.

[0043] The working process of the roughening equipment of the present invention is described as follows:

[0044] Start the equipment, and each module part returns to the origin. The guide rod cylinders used in the first up and down movement mechanism 250, the second up and down movement mechanism 350, the third up and down movement mechanism 450, and the pushing and pulling mechanism 540 should be in the contracted state; the lifting mechanism 530 should be in the extended state; the positions of the first lower pressing and positioning block 280 and the second lower pressing and positioning block 380 should be parallel to the horizontal and face upwards, facilitating the placement of the cable 10.

[0045] Place the front end of the cable 10 on the first lower pressing and positioning block 280, pass its middle part through the second lower pressing and positioning block 380, and pass its rear part through the third lower pressing and positioning block 440.

[0046] Start the grinding button. The first up and down movement mechanism 250 moves downward to press the front end of the cable 10. At the same time, the second up and down movement mechanism 350 moves downward to press the middle part of the cable 10, and the third up and down movement mechanism 450 moves downward to press the rear end of the cable 10. Then the grinding main shaft 551 starts, driving the grinding head 552 to rotate. At the same time, the lifting mechanism 530 descends and the pushing and pulling mechanism 540 extends to start the grinding work of the cable 10.

[0047] According to the program design, the transverse movement mechanism 520 starts the transverse movement, thus completing the grinding work of the cable 10 from point to line.

[0048] After completing the grinding work from point to line and after completing a transverse movement cycle, the driving mechanism one 220 of the front-end cable rotating module 200 and the driving mechanism two 320 of the intermediate cable rotating module 300 simultaneously step and rotate a specific angle, starting a new grinding route. At this time, the driving mechanism three 422 of the cable torque release module 400 drives it to move a specific distance towards the grinding side of the cable 10 to offset the torque brought by the rotation of the cable 10. This process is repeated until the entire circumference of the cable 10 is ground.

[0049] After all the cables 10 are ground, turn off the button of the electric control box to stop the grinding work.

[0050] The above description is only the preferred implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any transformation and replacement based on the technical solution and the inventive concept provided by the present invention should be covered within the protection scope of the present invention.
