Description

Technical Field

[0001] The present application relates to the technical field of skinning jigs, and in particular to a surrounding puncture and skinning jig. Background Art

[0002] Surround puncture and stripping jigs are widely used in various cable processing fields, especially in situations where efficient and accurate stripping of the insulation layer is required. With the rapid development of electronic equipment and communication technology, the demand for various types of cables has increased significantly, and the requirements for cable processing technology have become increasingly higher. The traditional manual stripping method is not only inefficient, but also easily damages the internal conductor of the cable, affecting product quality. Therefore, the development of efficient automated stripping tools has become an urgent need for the development of the industry. At present, there are many common solutions in the field of cable stripping. The first is to use a rotating blade for cutting, drive the blade to rotate at high speed through a motor, cut the surface of the cable, and then remove it manually or semi-automatically; the second is to use pneumatic pressing, squeeze the cable through high-pressure gas to break its surface, and then cooperate with the manipulator to grab the broken part to complete the stripping operation; there is also laser ablation technology, which accurately burns the cable surface by focusing the laser beam to achieve a rapid stripping effect. Although these methods have improved work efficiency to a certain extent, there are still some shortcomings.

[0006] By adopting the above technical solution, during the rotation of the driving arm, the first pushing part will sequentially push and move the moving part set on the mounting plate, so that the moving part drives the puncture needle to sequentially puncture the membrane-wrapped wire to be peeled that passes through the puncture hole. Since the rotation radius of the driving arm during the rotation process is the same, it can ensure that the puncture needle punctures the membrane-wrapped wire at the same depth, and a circle of openings are punctured on the membrane-wrapped wire, so that the outer layer of the membrane can be easily separated. Before the driving arm moves relative to the main frame, the unlocking part cannot contact the locking device, so that the driving arm can normally drive the puncture assembly to perform the peeling operation when it is not moved. After the driving arm moves relative to the main frame, the unlocking part can contact the locking device, so that during the rotation of the driving arm, the unlocking part can push the locking device to open the lock on the puncture needle, and lock the position of the puncture needle through the temporary limit device, and the first pushing part also pushes the moving part, thereby changing the position of the puncture needle relative to the moving part.

[0026] The present application is further described in detail below in conjunction with the accompanying drawings.

[0027] A surrounding piercing and peeling jig, referring to Figure 1 , including a main frame 1, a driving component 2 and a puncture component 3, wherein the driving component 2 and the puncture component 3 are both installed on the main frame 1, and the main frame 1 includes a mounting plate 11, a bottom plate 12 and a support rod 13, wherein the mounting plate 11 and the bottom plate 12 are both circular plate structures, and the two are arranged in parallel, and several support rods 13 connect the mounting plate 11 and the bottom plate 12, thereby forming a cylindrical main frame 1.

[0028] Reference Figure 2 and 5 The driving assembly 2 includes a driving arm 21 and a connecting ring 27, wherein the connecting ring 27 is disposed on the bottom plate 12 and can rotate relative to the bottom plate 12, the driving arm 21 is disposed in the connecting ring 27 and can rotate relative to the bottom plate 12 along with the connecting ring 27, the driving arm 21 extends between the mounting plate 11 and the bottom plate 12, and is bent between the mounting plate 11 and the bottom plate 12, so that the driving arm 21 can rotate in a circular manner in the main frame 1. The driving arm 21 has a first pushing portion 22, an unlocking portion 23 and a second pushing portion 24, an annular supporting groove 113 is disposed on the inner side of the mounting plate 11, and the second pushing portion 24 is inserted into the supporting groove 113, so that the rotation of the driving arm 21 is more stable. Two limit grooves 29 are provided on the inner arm of the connecting ring 27 along the axial direction, and the driving arm 21 is correspondingly provided with a limit block 28 which can protrude from the surface of the driving arm 21. The limit block 28 can be inserted into the limit groove 29, so that the connecting ring 27 and the driving arm 21 rotate synchronously. The two limit grooves 29 enable the driving arm 21 to be connected to the connecting ring 27 at two positions, thereby enriching the use function of the driving arm 21.

[0029] Reference Figure 2, the mounting plate 11 is provided with a plurality of puncture components 3, the puncture components 3 include a puncture needle 31, a moving member 32, a spring piece 33 and a locking device 34, the mounting plate 11 is provided with a puncture hole 111, and a plurality of puncture components 3 are radially distributed around the puncture hole 111, and the puncture needle 31 points to the puncture hole 111. The mounting plate 11 is provided with a connecting port 112, the moving member 32 is provided in the connecting port 112, and can move relative to the mounting plate 11 in the direction of the puncture hole 111, and the locking device 34 is provided in the moving member 32, the moving member 32 includes a moving portion 321 and an extending portion 322, the puncture needle 31 passes through the moving portion 321, and is locked in the moving portion 321 by the locking device 34. The extension part 322 is arranged below the moving part 321 and extends downward through the connection port 112. When the driving arm 21 rotates, the first pushing part 22 can push the extension part 322, so that the moving member 32 drives the puncture needle 31 to move in the direction of the puncture hole 111. The spring piece 33 is arranged in the connection port 112, one end of which is connected to the inner side wall of the connection port 112, and the other end is connected to the moving member 32, so that when the moving member 32 is not pushed, the moving member 32 can be pushed away from the puncture hole 111 by the spring piece 33, so that the puncture needle 31 leaves the puncture hole 111 when the moving member 32 is not pushed.

[0030] Reference Figure 2 and 4 The locking device 34 includes a clamping rod 341, a clamping spring 342 and an unlocking member 343. The unlocking member 343 passes through the extension portion 322 and bypasses both sides of the puncture needle 31 in the movable portion 321. The clamping rod 341 is connected above the puncture needle 31. The puncture needle 31 is provided with a plurality of clamping interfaces 311. The clamping rod 341 can be inserted into the clamping interface 311 from above the puncture needle 31, thereby forming a clamping connection to lock the puncture needle 31 in the movable portion 321. A clamping spring 342 is connected above the clamping rod 341. The upper side of the clamping spring 342 is connected to the top wall inside the movable portion 321, which is used to press the clamping rod 341 into the clamping interface 311 to maintain that the puncture needle 31 can be stably locked when there is no external force. The protruding extension part 322 below the unlocking member 343 can be lifted up by the unlocking member 23. When the unlocking member 23 is lifted up, the clamping rod 341 is driven to move upward, thereby releasing the clamping connection between the clamping rod 341 and the clamping interface 311, so that the puncture needle 31 can move relative to the moving member 32. When the unlocking member 23 rotates away from the unlocking member 343 along with the driving arm 21, the unlocking member 343 and the clamping rod 341 move downward under the action of the clamping spring 342, so that the clamping rod 341 is clamped with another clamping interface 311, thereby adjusting the position of the locking device 34 to lock the puncture needle 31.

[0031] Reference Figure 4A temporary limiting device 14 is provided in the mounting plate 11. The temporary limiting device 14 is used to temporarily limit and fix the puncture needle 31 when the locking device 34 unlocks the puncture needle 31. When the unlocking portion 23 pushes the locking device 34 to unlock, the first pushing portion 22 will also push the moving member 32 to move. When the moving member 32 is pushed, the position of the puncture needle 31 is limited by the temporary limiting device 14, thereby realizing the relative movement of the puncture needle 31 and the moving member 32. The temporary limiting device 14 includes a clamping plate 141 and a connecting rod 142. The clamping plate 141 can protrude from the surface of the mounting plate 11. The puncture needle 31 is provided with a plurality of clamping grooves 312 corresponding to the clamping plate 141. When the protrusion of the clamping plate 141 is clamped with the clamping groove 312, the puncture needle 31 is limited to the current position, so that when the moving member 32 is moved, the puncture needle 31 will not be driven. A connecting rod 142 is connected to the lower part of the clamping plate 141, and the connecting rod 142 passes through the mounting plate 11 and protrudes from the support groove 113. The second pushing portion 24 moves in the support groove 113. When the driving arm 21 is located away from the mounting plate 11, the second pushing portion 24 will not contact the connecting rod 142, and the clamping plate 141 will not protrude. When the driving arm 21 moves to a position close to the mounting plate 11, the second pushing portion 24 will push the connecting rod 142 upward during rotation, thereby pushing out the clamping plate 141, and forming a clamping connection with the clamping groove 312, thereby limiting the movement of the puncture needle 31.

[0032] Reference Figure 3 The first push part 22 has a first inclined surface 25, and the unlocking part 23 has a second inclined surface 26. The first inclined surface 25 and the second inclined surface 26 enable the first push part 22 to gradually push the moving part 32 and the unlocking part 23 to push the unlocking part 343 at a suitable speed, so that the pushing process is more stable and accurate. In addition, the second inclined surface 26 is located in front of the first inclined surface 25 along the rotation direction of the driving arm 21. Since it is necessary to release the clamping connection between the clamping rod 341 and the clamping interface 311 before pushing the moving part 32 relative to the puncture needle 31 during the process of adjusting the position, the second inclined surface 26 is arranged in front of the first inclined surface 25, so that before the first push part 22 starts to push the moving part 32, the unlocking part 23 has completed the unlocking of the puncture needle 31. In addition, the second pushing portion 24 is a straight structure. When the first pushing portion 22 contacts the moving part 32, it can push the connecting rod 142, so that when the driving arm 21 moves toward the mounting plate 11 and is in an unlocked state, the clamping plate 141 can be pushed up, and the puncture needle 31 can be limited and locked before the first pushing portion 22 starts to push the moving part 32.

[0033] The implementation principle of the embodiment of the present application is as follows: due to the curved structure of the driving arm 21, when the driving arm 21 rotates on the bottom plate 12, the first pushing portion 22 rotates in a circular ring shape, and the first pushing portion 22 has a first inclined surface 25, and the first inclined surface 25 can push the moving member 32 with the rotation of the driving arm 21, so that the puncture needle 31 punctures the surface layer of the membrane-wrapped wire, and by forming a circle of punctured openings, the membrane on the outside of the membrane-wrapped wire can be easily torn off. When the driving arm 21 is at a position away from the mounting plate 11, the unlocking portion 23 is located below the unlocking member 343, and the second pushing portion 24 is also located below the connecting rod 142, so that the rotation of the driving arm 21 can only push the moving member 32 to rotate. When the driving arm 21 is in a position close to the mounting plate 11, the unlocking portion 23 rises upward, so that the unlocking portion 23 can push the unlocking piece 343 to move upward, releasing the clamping of the puncture needle 31, and the second pushing portion 24 can push the connecting rod 142, so that the clamping plate 141 is clamped with the clamping groove 312, so that when the first pushing portion 22 pushes the moving piece 32, the puncture needle 31 and the moving piece 32 move relative to each other.

[0034] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
