[0010] As one embodiment of the present invention, the expansion port limiting plate includes two symmetrically arranged clamping plates, and a clamping groove is provided at the connection between the two clamping plates, and the expansion port connecting rod is movably engaged in the clamping groove.

[0011] As an embodiment of the present invention, the above-mentioned driving push block includes a push connecting seat and a wedge-shaped push block.

S4 Welding Fixing: Power is applied to the combined welding clamp to melt and fix the upper bent part of the clamping cable clamp.

[0014] The beneficial effects of this invention are: 1. This invention achieves fully automated operation of cable from fixing, extrusion deformation, clamping and merging to welding by setting up a clamping and fixing mechanism, an expansion and extrusion mechanism, and a merging and welding mechanism. Each operation step is precisely controlled by drive devices such as double-rod drive cylinders and expansion cylinders, which reduces manual intervention and greatly shortens the processing time. Operators only need to place the wire in the cable clamp and start the equipment to complete the entire end welding process, which improves production efficiency and reduces labor intensity. 2. This invention uses a double-rod drive cylinder to push a wedge-shaped push block, which in turn drives the clamping rotating rod to rotate around the rotating connecting column. This ensures that the clamping slot of the clamping fixture is precisely aligned with and clamps the bottom of the cable clamp. This ensures the stability of the cable clamp during subsequent processing, avoids welding deviations caused by cable clamp wobbling or displacement, thereby improving the accuracy and consistency of welding and guaranteeing the quality of the cable clamp's welded end. 3. The expansion and extrusion mechanism of the present invention utilizes an expansion cylinder to drive an expansion linkage rod and an expansion column, causing the expansion block to uniformly extrude the upper opening of the cable clamp. The cooperation of the expansion limiting plate, the expansion linkage rod, and the expansion column ensures the stability and accuracy of the expansion block during the extrusion process, enabling uniform bending deformation of the upper part of the cable clamp and ensuring consistent processing quality. 4. The merging welding mechanism of the present invention uses a double-rod drive cylinder to push a wedge-shaped push block, which drives the merging transmission rod to rotate around the rotating connecting column, so that the merging welding clamp can clamp the upper bent part of the cable clamp. At the same time, during the welding process, the merging welding clamp is energized, so that the upper bent part of the cable clamp is welded, melted and fixed, which improves the strength and sealing of the weld, avoids problems such as loosening or poor contact of the cable during subsequent use, and improves the service life and reliability of the cable clamp.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0018] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0019] Example 1, as Figures 1-9 As shown, this invention designs a novel cable clamp closing device, including a device mounting bracket 1. The device mounting bracket 1 includes a front end 11 and a rear end 12. The device mounting bracket 1 is provided with a clamping and fixing mechanism 2, an expansion and squeezing mechanism 3, and a merging and welding mechanism 4. The ends of the clamping and fixing mechanism 2 and the merging and welding mechanism 4 are each provided with a driving mechanism 7. The driving mechanism 7 includes a double-rod driving cylinder 71 and a driving push block 72. The reciprocating movement of the driving mechanism 7 drives the clamping and fixing mechanism 2 and the merging and welding mechanism 4 to move. The clamping and fixing mechanism 2 is used to clamp the cable clamp 5, the expansion and squeezing mechanism 3 is used to squeeze the cable clamp 5 and deform it, and the merging and welding mechanism 4 is used to close the cable clamp 5 and weld it closed. The expansion and squeezing mechanism 3 is located between the clamping and fixing mechanism 2 and the merging and welding mechanism 4.

[0020] Specifically, such as Figures 1-2 As shown, this novel wire clamp closing device mainly consists of an equipment mounting bracket 1, a clamping and fixing mechanism 2, an expansion and extrusion mechanism 3, a merging and welding mechanism 4, and a driving mechanism 7.

[0021] The equipment mounting bracket 1 serves as the supporting structure for the entire device, consisting of two lateral support plates 101 and two rotating connecting plates 102 connected in sequence to form a square receiving cavity 100. The two lateral support plates 101 are placed parallel to each other, and the two rotating connecting plates 102 are respectively vertically connected to both ends of the lateral support plates 101, and fixedly connected by bolts or other fasteners to ensure the structural stability of the receiving cavity 100. A first limiting groove 1011 is provided on the inner wall of each lateral support plate 101 for subsequent limiting installation of the expansion and extrusion mechanism 3.

[0022] like Figure 2As shown, within the accommodating cavity 100, a clamping and fixing mechanism 2, an expansion and extrusion mechanism 3, and a merging and welding mechanism 4 are sequentially arranged. The expansion and extrusion mechanism 3 is located between the clamping and fixing mechanism 2 and the merging and welding mechanism 4. The power for both the clamping and fixing mechanism 2 and the merging and welding mechanism 4 is provided by the drive mechanism 7, and the expansion and extrusion mechanism 3 is driven by the expansion cylinder 31.

[0023] Specifically, such as Figures 2-4 As shown, the expansion and extrusion mechanism 3 includes an expansion cylinder 31, a connecting fixing seat 32, and an expansion device 33. Two rotating connecting plates 102 are symmetrically fixed at one end to both sides of the connecting fixing seat 32, using a snap-fit ​​and screw connection method. Rotating connecting columns 6 are installed at the other end of the two rotating connecting plates 102, and the two ends of the rotating connecting columns 6 are respectively fixed to the ends of the two rotating connecting plates 102. Mounting holes are opened at the ends of the rotating connecting plates 102, and the rotating connecting columns 6 are then fixed with screws.

[0024] like Figures 3-4 As shown, a cylinder through hole 320 is provided in the connecting fixing base 32. The expansion cylinder 31 is installed on the rear side of the connecting fixing base 32, so that the expansion piston rod 311 of the expansion cylinder 31 passes through the cylinder through hole 320 and is connected to the front end of the expansion linkage rod 332. A lateral limiting groove 321 is provided at the end of the connecting fixing base 32 away from the expansion cylinder 31. The front end of the expansion limiting plate 331 is engaged in the lateral limiting groove 321. At the same time, the upper end and the lower end of the expansion limiting plate 331 are engaged in the first limiting groove 1011 on the inner wall of the lateral support plate 101, respectively, to ensure that the expansion limiting plate 331 is installed firmly.

[0025] The expansion device 33's expansion limiting plate 331 consists of two symmetrically arranged clamping plates 3312, with a clamping groove 3313 at the connection between the two clamping plates 3312. The expansion connecting rod 332 is movably engaged within the clamping groove 3313, ensuring smooth sliding within the groove 3313. A transverse limiting strip 3311 is provided on the side wall of the expansion limiting plate 331, and the drive mechanism 7 has a corresponding slot to hold the transverse limiting strip 3311, thereby enhancing the stability of the expansion limiting plate 331.

[0026] like Figure 3 , Figure 6 As shown, an expansion port limiting hole 60 is provided on the rotating connecting column 6. One end of the expansion port column 333 is snapped onto the expansion port connecting rod 332, and the other end of the expansion port column 333 is movably snapped into the expansion port limiting hole 60. An expansion port block 334 is installed at the front end of the expansion port column 333. The expansion port block 334 is in the shape of an inverted step.

[0027] like Figure 5 and Figure 6As shown, the clamping and fixing mechanism 2 includes two symmetrically arranged clamping rotating rods 21. A first tensioning block 22 is rotatably mounted at the front end of each clamping rotating rod 21. A mounting hole is formed at the front end of each clamping rotating rod 21, and the first tensioning block 22 is mounted in the mounting hole via a rotating shaft. The rear end of each clamping rotating rod 21 is rotatably sleeved on a rotating connecting post 6, ensuring that the clamping rotating rod 21 can rotate flexibly around the rotating connecting post 6. A clamping fixture 23 is provided at the rear end of each clamping rotating rod 21, and a wire clamp groove 230 is provided at the center of the clamping fixture 23. The size of the wire clamp groove 230 matches the size of the cable clamp 5.

[0028] like Figure 5 and Figure 8 As shown, the merging welding mechanism 4 includes two symmetrically arranged merging transmission rods 41. A second tensioning block 42 is rotatably mounted at the front end of each merging transmission rod 41, and its installation method is the same as that of the first tensioning block 22 housing. The rear end of each merging transmission rod 41 is rotatably sleeved on the rotating connecting column 6. A merging welding fixture 43 is set at the rear end of each merging transmission rod 41, and a merging welding chuck 431 is set at the front end of each merging welding fixture 43. The merging welding chuck 431 is made of a metal material with good electrical conductivity and requires a certain degree of hardness to facilitate subsequent clamping and welding operations.

[0029] like Figures 5-8 As shown, the drive mechanism 7 is provided in two sets. The drive mechanism 7 includes a double-rod drive cylinder 71 and a drive push block 72. The drive push block 72 includes a push connecting seat 721 and a wedge-shaped push block 722. One end of the push connecting seat 721 is connected to the piston rod of the double-rod drive cylinder 71 by a threaded connection. The two drive mechanisms 7 are respectively installed at the ends of the clamping and fixing mechanism 2 and the merging and welding mechanism 4. The two first tensioning blocks 22 abut against the inclined surface of the wedge-shaped push block 722 corresponding to the clamping and fixing mechanism 2, and the two second tensioning blocks 42 abut against the inclined surface of the wedge-shaped push block 722 corresponding to the merging and welding mechanism 4.

[0030] Since the inclined surface of the wedge-shaped push block 722 is smaller at the front end and larger at the rear end, the more the wedge-shaped push block 722 moves forward, the more the first tension block 22 and the second tension block 42 will receive an outward pushing force, which will drive the clamping rotating rod 21 or the merging transmission rod 41 to rotate, thereby causing the clamping fixture 23 to clamp the cable clamp 5, or to merge the upper part of the clamping cable clamp 5 with the merging welding chuck 431.

[0031] like Figures 1-9 The diagram shown is a flowchart of the processing of the cable clamp 5 of the present invention. The specific steps of the novel cable clamp welding process of the present invention are as follows: S1 Clamping and Fixing: Place the wire in the cable clamp 5, activate the double-rod drive cylinder 71 connected to the clamping and fixing mechanism 2. The piston rod of the double-rod drive cylinder 71 pushes the push connecting seat 721, thereby driving the wedge-shaped push block 722 to move forward. Since the first tensioning block 22 abuts against the inclined surface of the wedge-shaped push block 722, the movement of the wedge-shaped push block 722 will cause the first tensioning block 22 to be subjected to an oblique thrust, thereby driving the clamping rotating rod 21 to rotate around the rotating connecting column 6, so that the wire clamp groove 230 at the center of the clamping fixture 23 is aligned with and clamps the bottom of the cable clamp 5, ensuring that the cable clamp 5 is fixed in position during subsequent operations.

[0032] S2 Cable Clamp Expansion: The expansion cylinder 31 is activated, and its expansion piston rod 311 extends forward, pushing the expansion linkage rod 332 to slide within the clamping groove 3313 of the expansion limit plate 331. The movement of the expansion linkage rod 332 causes the expansion column 333 to move within the expansion limit hole 60, causing the expansion block 334 at the front end of the expansion column 333 to press against the upper opening of the cable clamp 5. As the expansion block 334 continues to press, the upper part of the cable clamp 5 gradually bends and transforms into the shape of the expansion block 334, thus achieving the expansion operation of the cable clamp 5.

[0033] S3 Press Forming: The double-rod drive cylinder 71 connected to the merging welding mechanism 4 is activated. The piston rod of the double-rod drive cylinder 71 pushes the corresponding push connecting seat 721, causing the wedge-shaped push block 722 to move forward. Since the second tension block 42 abuts against the inclined surface of the wedge-shaped push block 722, the movement of the wedge-shaped push block 722 causes the second tension block 42 to be subjected to an oblique thrust, causing the merging transmission rod 41 to rotate around the rotating connecting column 6, so that the merging welding chuck 431 at the front end of the merging welding fixture 43 clamps the upper curved part of the cable clamp 5, merging the upper curved part of the clamped cable clamp 5, preparing for subsequent welding operations.

[0034] S4 Welding and Fixing: Power is applied to the merging welding clamp 431. Since the merging welding clamp 431 is in contact with the upper bent portion of the cable clamp 5, heat is generated when the current passes through, causing the upper bent portion of the clamping cable clamp 5 to melt and fix in place. After welding is completed, the power is disconnected, and the cable clamp 5 is allowed to cool, completing the entire clamp finishing welding process.

[0035] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0036] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
