Description

Technical Field

[0002] A positioning device for welding cable accessories is a device specifically used for positioning and fixing during the welding process of cable accessories. Its design purpose is to improve welding accuracy, ensure welding quality, and improve production efficiency.

[0003] In the existing technology, firstly, for some devices, the cables may not receive uniform and stable pressure, resulting in the displacement of the cable position during the welding process, affecting the welding quality. Manually fixing the cables requires more time and labor, reducing the operation efficiency. Manual fixing may have instability and unpredictability, increasing the safety risks during the operation. Secondly, for some devices, the clamping process may require more time and steps, reducing the overall working efficiency, and it is difficult to achieve the rapid installation and disassembly of the hydraulic fixing mechanism and the fixing base plate. Finally, for some devices, the position adjustment of the rotating sleeve will become difficult, possibly requiring more time and tools. Without the additional support provided by the auxiliary mechanism, the stability of the clamping part may decrease, affecting the accuracy during the welding process. Summary of the Utility Model

[0030] In this embodiment, the hydraulic cylinder 2 is installed on the pressing seat 5 and connected to the fixed bottom plate 1 through the first piston rod 3 and the second piston rod 4. When the hydraulic cylinder 2 is activated, it pushes the first piston rod 3 and the second piston rod 4, causing the second piston rod 4 to move downward.

Further, the slope pushing block 16 will push the pressed block 17, so that the extending rod 13 and the clamping rod 10 are quickly clamped. At this time, the limiting clip 27 can move downward to clamp the rotating block 19 and fix the position of the rotating sleeve 15. When it is necessary to unlock the rotating sleeve 15, rotate the directional pushing tube 26 in the reverse direction, and utilize the moving force of the moving spring 21 to realize the reverse rotation of the rotating sleeve 15. At this time, the tension spring 14 pulls out the extending rod 13 to release the clamping.

[0033] Please refer to Figures 1-5 , as a supplementary implementation method of a positioning device for welding a cable accessory for the hydraulic fixing mechanism, the quick clamping mechanism and the clamping auxiliary mechanism: a connecting plate 23 is installed at the bottom end of the side wall of the clamping tube 9.

A threaded sleeve 29 is installed at the top of the illustrated bearing. The inner wall of the threaded sleeve 29 is threadedly connected to the outer wall of the clamping tube 9 in a cooperative manner. Lateral plates 30 are installed at both ends of the pressing seat 5. The connecting plate 23 at the bottom end of the side wall of the clamping tube 9 is fixedly installed on the lateral plates 30. One end of the clamping rod 10 is connected to the fixed bottom plate 1 in a cooperative manner. The other end of the clamping rod 10 extends through the lateral plate 30 and is quickly clamped with the clamping tube 9 in a cooperative manner. A placement groove 31 is opened at the center position of the fixed bottom plate 1. The external cable is placed in the placement groove 31. The rubber block 8 is arranged opposite to the placement groove 31.

[0034] More specifically, place the external cable in the placement groove 31 of the fixed base plate 1. Activate the hydraulic fixing mechanism. Through the cooperation of the hydraulic cylinder 2, the live rod, and the pressure rod 6, the rubber block 8 presses the cable tightly to fix the position of the cable. The quick clamping mechanism makes the clamping rod 10 and the extending rod 13 quickly clamped or unlocked through the cooperation of the rotating sleeve 15 and the slope pushing block 16, realizing the quick installation and disassembly of the hydraulic fixing mechanism and the fixed base plate 1. The clamping auxiliary mechanism realizes the precise adjustment of the rotating sleeve 15 through the cooperation of the directional rotating tube 18, the rotating block 19, the movement spring 21, and the directional pushing tube 26, thereby controlling the position of the clamping rod 10.

[0035] In summary, when the overall device is in use or operation: When the operation of the hydraulic fixing mechanism is required, the hydraulic cylinder 2 is installed on the pressing seat 5 and connected to the fixed base plate 1 through the first live rod 3 and the second live rod 4. When the hydraulic cylinder 2 is activated, it pushes the first live rod 3 and the second live rod 4, causing the second live rod 4 to move downward. One end of the pressure rod 6 is hinged to the fixed base plate 1 and the first live rod 3. As the second live rod 4 moves, the pressure rod 6 will also move downward. The pressing rod 7 is installed on the pressure rod 6, and a rubber block 8 is installed on its top. When the pressure rod 6 moves downward, the rubber block 8 will tightly press the cable placed in the placement groove 31 of the fixed base plate 1, thereby fixing the position of the cable.

[0036] When the operation of the quick clamping mechanism is required to realize the quick installation and disassembly of the hydraulic fixing mechanism and the fixed base plate 1, the clamping rod 10 extends into the clamping tube 9. The card slot 11 is arranged on the side of the clamping rod 10. The extending rod 13 movably extends horizontally into the clamping tube 9.

The rotating sleeve 15 is rotatably arranged outside the clamping tube 9. The slope pushing block 16 is arranged on the inner wall of the rotating sleeve 15. The pressure receiving block 17 is arranged at one end of the extending rod 13. When the rotating sleeve 15 rotates, the slope pushing block 16 will push the pressure receiving block 17, causing the extending rod 13 and the clamping rod 10 to be quickly clamped.

[0037] When the operation of the clamping auxiliary mechanism is required, rotate the directional rotating tube to drive the rotating block 19 outside the fixed sleeve 20 to rotate. The rotating block 19 drives the rotating sleeve 15 to rotate. Furthermore, the slope pushing block 16 will push the pressure receiving block 17, causing the extending rod 13 and the clamping rod 10 to be quickly clamped. At this time, the limiting clamp 27 can move downward to clamp the rotating block 19 and fix the position of the rotating sleeve 15. When it is necessary to unlock the rotating sleeve 15, rotate the directional pushing tube 26 in the reverse direction, and using the movement force of the movement spring 21, the rotating sleeve 15 can be rotated in the reverse direction. At this time, the tension spring 14 pulls out the extending rod 13 to release the clamping.

[0038] Place the external cable in the placement groove 31 of the fixed base plate 1. Activate the hydraulic fixing mechanism. Through the cooperation of the hydraulic cylinder 2, the live rod and the pressure rod 6, the rubber block 8 presses the cable tightly to fix the position of the cable. The quick clamping mechanism enables the clamping rod 10 and the extending rod 13 to be quickly clamped or unlocked through the cooperation of the rotating sleeve 15 and the slope pushing block 16, realizing the quick installation and disassembly of the hydraulic fixing mechanism and the fixed base plate 1. The clamping auxiliary mechanism realizes the precise adjustment of the rotating sleeve 15 through the cooperation of the directional rotating tube 18, the rotating block 19, the movement spring 21 and the directional pushing tube 26, so as to control the position of the clamping rod 10.
