When the situation occurs, by adjusting the fine adjustment mechanism 700, the pressing blocks 600 which do not abut against the outer wall of the cable 800 move in the radial direction of the cable positioning and clamping cavity 140 until the pressing blocks abut against the outer wall of the cable 800, so that all the pressing blocks 600 abut against the outer wall of the cable 800, and the clamping effect is ensured.
Further, fine-tuning 700 includes adjusting screw 710, spring guide 720 and spring 730, and adjusting screw 710 and spring guide 720 are along the radial parallel arrangement of cable location centre gripping chamber 140, and spring guide 720 is mobilizable to be worn to establish on grip block 130, and is connected with compact heap 600, and the cover is equipped with the spring 730 that is in compression state on the spring guide 720, and the one end butt of spring 730 is at the back of compact heap 600, and adjusting screw 710 passes grip block 130 and the back butt of compact heap 600.
As shown in fig. 4 and 6, when the pressing block 600 is finely adjusted, by rotating the adjusting screw 710, when the adjusting screw 710 is screwed in, the adjusting screw 710 pushes the pressing block 600 to move toward the radial direction of the cable positioning and clamping cavity 140 until the pressing block 600 abuts against the outer wall surface of the cable 800. When the pressing block 600 moves, the spring guide rod 720 connected with the pressing block moves synchronously with the pressing block, and the spring 730 sleeved on the spring guide rod 720 can enable the pressing plate 600 to cling to the cable 800.
Further, two adjusting screws 710 of the fine adjustment mechanism 700 are respectively disposed at two sides of the spring guide rod 720. Each fine adjustment mechanism 700 comprises two adjusting screws 710 which are symmetrically arranged on two sides of the spring guide rod 720, and the two adjusting screws 710 are adjusted simultaneously during fine adjustment, so that the stress of the pressing block 600 is more uniform.
In some embodiments of the present invention, the adjusting mechanism includes a dual left-right screw 510, a first threaded sleeve 520, a second threaded sleeve 530 and a connecting beam 540, the connecting beam 540 is transversely disposed at the upper ends of the two guide rods, two ends of the connecting beam 540 are respectively connected to the corresponding guide rods, a first threaded section and a second threaded section are disposed on the body of the dual left-right screw 510, the threads of the first threaded section and the second threaded section are oppositely disposed, the first threaded sleeve 520 is sleeved and screwed on the first threaded section, the second threaded sleeve 530 is sleeved and screwed on the second threaded section, the first threaded sleeve 520 is disposed on the connecting beam 540, and the second threaded sleeve 530 is disposed on the clamping block 300 slidably connected to the guide rods.
When the adjusting mechanism is used to adjust the distance between the two clamping blocks 130, as shown in fig. 4, we will take the action of clamping the cable 800 as an example.
When the double left-right screw 510 is rotated, the first threaded sleeve 520 moves upward under the driving force of the threads of the first threaded section, so as to drive the connecting beam 540 to move upward, the connecting beam 540 drives the guide rod to move upward, and the clamping block 130 connected to the lower part of the guide rod moves upward. At this time, because the threads of the first thread section and the second thread section are reversed, the second thread sleeve 530 moves downward under the action of the second thread section, and drives the clamping blocks 130 slidably connected with the guide rod to slide downward, so that the two clamping blocks 130 move in opposite directions, and finally the clamping action on the cable 800 is completed. When the cable 800 is loosened, the bidirectional left-right screw 510 rotates reversely.
As shown in fig. 2, during the whole adjustment process, since the upper and lower clamping blocks 130 move synchronously, the axial position of the cable positioning clamping cavity 140 is always kept unchanged under the condition of fixing the position of the supporting plate 110 and fixing. And the three-point positioning of the fixed supporting plate 110 is adopted to realize the three-center concentricity of the center of the cable positioning and clamping cavity 140, the rotation center of the cable polishing processing device 900 and the shaft center of the cable 800, so that the cable polishing processing device 900 is always in the correct position in the operation process.
Further, an auxiliary rotating handle 511 is arranged on the bidirectional left-right rotating screw 510. The bi-directional left-right rotation screw 510 is conveniently rotated by providing the auxiliary rotation handle 511 without the aid of an external tool.
