[0002] There are many situations in electronic devices and appliances where movable connecting wires are used, such as USB cables. These connecting wires are usually sheathed and then placed on a terminal crimping machine for crimping. After crimping, the sheath is pulled to fit over the connection end between the wire and the terminal, preventing the interface between the wire and the terminal or with other electrical components from being directly exposed, thus avoiding safety hazards.

[0003] Patent CN220042550U discloses a wire end-crimping and sleeve-making machine, which achieves riveting and unloading through the cooperation of a terminal crimping machine, a feeding mechanism, and a wire pulling mechanism. However, the clamping component of the feeding mechanism usually adopts a rack and pinion drive. This drive structure consists of multiple gears, racks, and connectors. The number of parts is large and the interrelationships between them are complicated, which not only increases the difficulty of manufacturing and assembly, but also increases the production and maintenance costs. Furthermore, it is difficult to precisely adjust the force of the clamps, which can easily lead to over-clamping and damage to the sleeve on the terminal, affecting the production quality of the product.

[0027] This specific embodiment is a sleeve riveting mechanism, the structural diagram of which is shown below. Figures 1-7 As shown, the mechanism includes a terminal crimping machine 1, a feeding assembly 2, and a wire pulling assembly 3. The terminal crimping machine 1 is used to crimp the tubing wire. The feeding assembly 2 is used to clamp the tubing end of the wire and drives the wire through the terminal crimping machine 1 and the wire pulling assembly 3 in sequence. The wire pulling assembly 3 is used to clamp the other end of the wire and unload it. The feeding assembly 2 includes a mounting frame 4, a lead screw 5, a feeding motor 6, a movable block 7, and two grippers 8. The lead screw 5 is rotatably connected between the left and right inner walls of the mounting frame 4. The feeding motor 6 is used to drive the lead screw 5 to rotate. The movable block 7 is slidably connected to the mounting frame 4 and slides along the lead screw. 5. A threaded connection is provided. A fixed seat 9 is fixedly connected to the upper surface of the movable block 7. An installation cavity 10 is provided inside the fixed seat 9. A swing block 11 is rotatably connected inside the installation cavity 10. The installation ends of the two grippers 8 are slidably connected inside the installation cavity 10 and are movably connected to both ends of the swing block 11. A drive cylinder 12 is fixedly connected to one side of the fixed seat 9. The output end of the drive cylinder 12 is located inside the installation cavity 10 and is fixedly connected to the installation block 13. A first pin 14 is provided inside the installation block 13 through an adjustment component. The bottom end of the swing block 11 is movably connected to the first pin 14.

[0028] After the wire is fitted with a tube, it is placed between the two grippers 8 of the feeding assembly 2. Then, the drive cylinder 12 is started to move the mounting block 13 and the first pin 14 to the left. During the movement, the first pin 14 can drive the swing block 11 to rotate around the center. At this time, the two top ends of the swing block 11 move in opposite directions, causing the two grippers 8 to move closer to each other, thereby holding the tube of the wire with the two grippers 8. Compared with the rack and pinion drive method, the structure is simpler and reduces the processing steps and processing costs.

[0029] like Figure 4 and Figure 5As shown: In this embodiment, the adjustment component includes a through hole 1301 between the upper and lower sides of the mounting block 13. A rectangular frame 1302 is slidably connected inside the through hole 1301. An adjustment screw 1303 is threadedly connected to the left side of the mounting block 13. The other end of the adjustment screw 1303 is rotatably connected to the rectangular frame 1302. A first pin 14 is fixedly connected inside the rectangular frame 1302.

[0030] By rotating the adjusting screw 1303, one end of the adjusting screw 1303 is threadedly connected to the mounting block 13, and the other end of the adjusting screw 1303 is rotatably connected to the left side of the rectangular frame 1302 through a bearing. At this time, the adjusting screw 1303 can move the rectangular frame 1302 to the right during the rotation. During the movement of the rectangular frame 1302 to the right, it can drive the first pin 14 to move, thereby driving the bottom end of the swing block 11 to move, causing the swing block 11 to rotate around the middle, so that the two grippers 8 can be relaxed. This allows for precise fine adjustment of the gripper force, avoiding the situation where the tube sleeve is worn on the terminal due to excessive clamping, thus improving the production quality of the product.

[0031] To prevent the adjusting screw 1303 from rotating arbitrarily, such as Figure 4 and Figure 5 As shown: In this embodiment, a locking nut 1304 is threaded onto the outer surface of the left end of the adjusting screw 1303. Guide grooves 1305 are provided on the inner walls of both the front and rear sides of the through hole 1301. Slider blocks 1306 corresponding to the guide grooves 1305 are fixedly connected to both the front and rear sides of the rectangular frame 1302. The cooperation between the guide grooves 1305 and the sliders 1306 prevents the rectangular frame 1302 from rotating with the adjusting screw 1303. After adjusting the position of the first pin 14, the locking nut 1304 is tightened to prevent the adjusting screw 1303 from rotating and improve the stability during use.

[0032] like Figure 4-6 As shown: In this embodiment, the bottom end of the swing block 11 is provided with a first elongated hole 1101, and the first pin 14 is located inside the first elongated hole 1101. The swing block 11 has a triangular structure as a whole, and the middle part of the swing block 11 is rotatably connected to the inner wall of the mounting cavity 10 through the second pin 1102. In this way, the first pin 14 can move inside the first elongated hole 1101. Through the cooperation between the first pin 14 and the first elongated hole 1101, the swing block 11 swings around the second pin 1102 in the middle.

[0033] To facilitate the installation of the mounting bracket 9 and internal parts, such as Figure 3 , Figure 4 and Figure 7As shown: In this embodiment, the fixing base 9 includes a fixing block 901 and a cover plate 902. The fixing block 901 and the cover plate 902 are fixedly connected by screws. The mounting cavity 10 includes a vertical groove 1001 and a horizontal groove 1002 formed on the fixing block 901. The vertical groove 1001 passes through the upper and lower sides of the fixing block 901. The horizontal groove 1002 communicates with the vertical groove 1001 and passes through the side of the fixing block 901. The output end of the drive cylinder 12 passes through the horizontal groove 1002.

[0034] To make the up-and-down sliding of gripper 8 more stable, such as Figure 4 and Figure 7 As shown: In this embodiment, the gripper 8 has an L-shaped structure. The inner walls of the left and right sides of the vertical groove 1001 are provided with sliding grooves 1003. The mounting end of the gripper 8 is slidably connected to the inside of the sliding groove 1003 and is provided with a U-shaped groove 801. The inner wall of the U-shaped groove 801 is fixedly connected with a third pin 802. The left and right ends of the swing block 11 are provided with second elongated holes 1103. The third pin 802 is located inside the second elongated holes 1103. In this way, the third pin 802 can move in the second elongated holes 1103. The mounting end of the gripper 8 slides up and down in the sliding groove 1003. When the swing block 11 swings, the two grippers 8 can move closer or further away from each other.

[0035] To make the movement of moving block 7 more stable, such as Figure 1 and Figure 2 As shown: In this embodiment, a slider 701 is fixedly connected to the lower surface of the movable block 7, and a guide rail 702 is fixedly connected to the upper surface of the mounting bracket 4. The guide rail 702 is slidably connected to the slider 701.

[0036] Working principle: After the wire is fitted with the tubing, it is placed between the two grippers 8 of the feeding assembly 2. Then, the drive cylinder 12 is activated to move the mounting block 13 and the first pin 14 to the left (e.g., Figure 4 As shown), during the movement of the first pin 14, the swing block 11 can rotate around the second pin 1102. At this time, the two movement directions of the top of the swing block 11 are opposite. Through the cooperation of the second elongated hole 1103 and the third pin 802, the two grippers 8 are brought closer to each other, thereby clamping the tube of the wire through the two grippers 8. Then, the feeding motor 6 is started to drive the lead screw 5 to rotate. Since the lead screw 5 is threadedly connected to the movable block 7, the lead screw 5 can drive the movable block 7, the fixed seat 9 and the grippers 8 to move during the rotation, driving the wire through the processing position of the terminal machine 1 for riveting. After the riveting is completed, the feeding assembly 2 moves to one side of the wire pulling assembly 3. The wire pulling assembly 3 fixes the side of the wire that has not been terminalized and moves it a certain distance away from the tube. At this time, the tube is sleeved on the connection end between the terminal and the wire. Finally, the feeding assembly 2 releases the tube, and the wire pulling assembly 3 unloads the wire.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
