Description

Technical Field

[0001] This invention relates to the field of cable welding machine technology, and in particular to a multi-head cable welding machine. Background Technology

[0002] A cable welding machine is an automated or semi-automatic device specifically designed for welding connections between cables (such as wires, cables, conductors, etc.) or between cables and other electronic components (such as terminals, connectors, joints, etc.). Through specific welding processes, it permanently connects the conductor parts of cables (usually metals such as copper or aluminum), ensuring that the connection has good conductivity, mechanical strength, and stability.

[0003] Multi-head cable welding machines are welding machines with multiple welding ends, used to process cable welding operations. In the existing multi-head welding machine welding operation, it is necessary to align the positions of multiple cables in advance to ensure that there will be no positional deviation in the subsequent welding operation. However, this welding operation requires a lot of time for the preparation of cable welding in advance. In the actual welding process, thicker cables cannot be rotated and adjusted by themselves, resulting in poor welding effect. It is necessary to manually rotate the cable welding point, which makes the welding efficiency slow. Summary of the Invention

[0004] To save time spent manually adjusting cable alignment and thus improve cable welding efficiency, the present invention adopts the following technical solution:

[0005] A multi-head cable welding machine includes a base and a second connecting plate. The base is provided with a stabilizing frame at both ends. The inner circumferential surface of the stabilizing frame is provided with a balance groove and an embedded groove. A rotating frame is rotatably provided on the stabilizing frame. A balance arc plate that is rotatably fitted with the balance groove is provided on the outer ring of the rotating frame. The second connecting plate is provided with a connecting mechanism at both ends. A limiting plate is provided on the rotating frame.

[0006] The rotating frame has an installation groove, and the outer surface of the rotating frame has a rotating groove located outside the installation groove. A spur gear is rotatably installed in the rotating groove. The spur gear is rotatably fitted with the rotating groove through a connecting ring. The spur gear is provided with a clamping mechanism for clamping the cable end. The clamping mechanism includes a first clamping plate fixedly connected to the outer surface of the spur gear.

[0007] Preferably, a second clamping plate is slidably fitted on the outer surface of the spur gear, a groove is formed on the outer surface of the spur gear, and a slider is provided on the inner side of the second clamping plate that is slidably fitted with the groove.

[0008] Preferably, both ends of the first clamping plate and both ends of the second clamping plate are provided with spring cylinders, and a connecting rod is movably fitted inside the spring cylinder. Both ends of the connecting rod are provided with a return spring that connects to the inner cavity of the spring cylinder.

[0009] Preferably, the outer surface of the first clamping plate is provided with an anti-rotation plate, and the inner ring surface of the second clamping plate is provided with a pad.

[0010] Preferably, the connecting mechanism is rotatably mounted with the rotating frame, and the inner surface of the rotating frame is provided with a first connecting plate, on which a welding machine for cable welding is provided.

[0011] Preferably, the inner surface of the rotating frame is provided with an internal toothed ring, the connecting mechanism includes a rotating ring that is rotatably fitted with the rotating frame, and an external suspension is provided on the outer surface of the rotating ring.

[0012] Preferably, the rotating ring is provided with a first ring frame, the bottom end of the first ring frame is provided with teeth that mesh with and match the spur gear, and the first ring frame is also provided with a second ring frame.

[0013] Preferably, the first clamping plate is provided with an anti-rotation plate that matches the sliding limit of the second ring frame, the outer side of the stabilizing frame is provided with an extrusion arc plate for squeezing the second clamping plate close to the first clamping plate, and the top of the stabilizing frame is provided with a wire stop plate for controlling the cable welding point.

[0014] Preferably, the bottom of the second connecting plate is provided with a drive shaft, and both ends of the drive shaft are provided with drive gears that mesh with the internal gear ring.

[0015] Preferably, the top surface of the second connecting plate is provided with a drive motor, the bottom end of the output shaft of the drive motor is provided with a driving bevel gear, and the middle section of the transmission shaft is provided with a driven bevel gear that meshes with the driving bevel gear.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. By using the rotating frame and the cooperation between the spur gear and the wire clamping mechanism, the two cables can be loaded, welded and unloaded in a streamlined operation. According to the meshing and matching between the spur gear and the teeth, the two cables can rotate 360 ​​degrees during the welding operation of the welding machine, thereby improving the welding effect between the two cables. Moreover, there is no need for manual adjustment of the welding position, which effectively improves the welding efficiency of the cables.

[0018] 2. By setting up a stabilizing frame and a connecting mechanism, and utilizing the cooperation between the anti-rotation plate and the second ring frame, as well as the cooperation between the second clamping plate and the extrusion arc plate, the second clamping plate can be adjusted according to the position of the spur gear relative to the stabilizing frame, so as to facilitate its cooperation with the first clamping plate to clamp and release the cable, and facilitate the clamping operation of the cable.

[0019] 3. By setting up the wire baffle, the synchronous rotation between the two rotating frames allows the distance between the two cables to be adjusted during the insertion and clamping operation to meet different welding requirements. Furthermore, the two cables will automatically align before welding to prevent welding point misalignment.

[0020] In summary, this invention overcomes the shortcomings of the prior art. By setting up a rotating frame, two cables can be loaded, welded, and unloaded in a streamlined operation. Furthermore, the cables can be welded 360 degrees during welding, which improves the efficiency of the welding process and has high social value and application prospects.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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 some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] Reference Figures 1 to 8 A multi-head cable welding machine includes a base 1 and a second connecting plate 4. Both ends of the base 1 are provided with a stabilizing frame 2. The inner circumferential surface of the stabilizing frame 2 is provided with a balance groove 201 and an embedded groove 202. A rotating frame 3 is rotatably provided on the stabilizing frame 2. The outer ring of the rotating frame 3 is provided with a balance arc plate 31 that is rotatably fitted with the balance groove 201. Both ends of the second connecting plate 4 are provided with a connecting mechanism 42. The rotating frame 3 is provided with a limiting plate 5.

[0034] The rotating frame 3 has a mounting groove 32, and a rotating groove 35 located outside the mounting groove 32 is formed on the outer surface of the rotating frame 3. A spur gear 6 is rotatably mounted in the rotating groove 35. The spur gear 6 is rotatably fitted with the rotating groove 35 via a connecting ring 61. The spur gear 6 is provided with a wire clamping mechanism 7 for clamping the cable end. The wire clamping mechanism 7 includes a first clamping plate 701 fixedly connected to the outer surface of the spur gear 6. Figure 1 As shown, the welding machine rotates clockwise to perform a streamlined process of cable loading, clamping, rotary welding, and unloading.

[0035] Specifically, refer to Figure 7 and Figure 8A second clamping plate 702 is slidably fitted on the outer surface of the spur gear 6. A groove 601 is provided on the outer surface of the spur gear 6. A slider 7021 is provided on the inner side of the second clamping plate 702, which is slidably fitted with the groove 601. Under the sliding cooperation between the slider 7021 and the groove 601, the second clamping plate 702 can slide on the surface of the spur gear 6, thereby allowing the second clamping plate 702 to move closer to and away from the first clamping plate 701, in order to complete the clamping and releasing operation of the cable.

[0036] Specifically, refer to Figure 7 and Figure 8 Both ends of the first clamping plate 701 and both ends of the second clamping plate 702 are provided with spring cylinders 705. A connecting rod 706 is movably fitted inside the spring cylinder 705. Both ends of the connecting rod 706 are provided with return springs 707 whose ends are connected to the inner cavity of the spring cylinder 705. When the second clamping plate 702 moves closer to the first clamping plate 701, the return spring 707 will undergo compression elastic deformation as the second clamping plate 702 moves. When the second clamping plate 702 moves away from the first clamping plate 701, the return spring 707 will restore its elastic deformation.

[0037] Specifically, refer to Figure 7 and Figure 8 The outer surface of the first clamping plate 701 is provided with an anti-rotation plate 703, and the inner ring surface of the second clamping plate 702 is provided with a pad strip 704.

[0038] Example 2

[0039] Reference Figures 1 to 8 The difference between this embodiment and embodiment 1 is that the connecting mechanism 42 and the rotating frame 3 are rotatably mounted together. The inner surface of the rotating frame 3 is provided with a first connecting plate 34. The first connecting plate 34 is provided with a welding machine 302 for cable welding. The rotating frame 3 is connected to both ends of the first connecting plate 34. There are three first connecting plates 34 and three welding machines 302. The welding machine 302 is only in the open state when the spur gear 6 and the tooth 4203 are meshing and matching. The welding machine 302 stops working when the spur gear 6 and the tooth 4203 finish meshing and matching.

[0040] Specifically, refer to Figure 6 The inner surface of the rotating frame 3 is provided with an internal toothed ring 33. The connecting mechanism 42 includes a rotating ring 4201 that is rotatably fitted with the rotating frame 3. An external suspension 421 is provided on the outer surface of the rotating ring 4201. The external suspension 421 is used to connect with an external support structure. When the device is running, the connecting mechanism 42 as a whole is always stationary relative to the external support structure.

[0041] Specifically, refer to Figures 4 to 6The rotating ring 4201 is provided with a first ring frame 4202. The bottom end of the first ring frame 4202 is provided with teeth 4203 that mesh with the spur gear 6. The first ring frame 4202 is also provided with a second ring frame 4204. With the setting of the second ring frame 4204, when the spur gear 6 drives the first clamping plate 701 to rotate, the outer arc surface of the anti-rotation plate 703 will contact the outer arc surface of the second ring frame 4204, thereby stopping the first clamping plate 701 from rotating. This prevents the second clamping plate 702 from being unable to approach the first clamping plate 701 under the squeezing and limiting action of the squeezing arc plate 203 during the subsequent clamping process.

[0042] Specifically, refer to Figure 1 , Figure 2 , Figure 4 , Figure 7 and Figure 8 The first clamping plate 701 is provided with an anti-rotation plate 703 that matches the sliding limit of the second ring frame 4204. The outer side of the stabilizing frame 2 is provided with a pressing arc plate 203 for pressing the second clamping plate 702 close to the first clamping plate 701. The top of the stabilizing frame 2 is provided with a wire stop plate 21 for controlling the welding point of the cable. The thickness of the wire stop plate 21 can be adjusted according to the actual welding process. When the required welding distance between the two cables is large, the thickness of the wire stop plate 21 can be increased to control the distance between the two cables, and vice versa. In addition, the setting of the wire stop plate 21 can help the two cables to be aligned after the spur gear 6 is inserted, so that the welding point between the two is aligned with the output end of the welding machine 302, avoiding the problem of welding position deviation affecting the welding effect.

[0043] Specifically, refer to Figure 3 and Figure 6 The bottom of the second connecting plate 4 is provided with a drive shaft 43, and both ends of the drive shaft 43 are provided with drive gears 432 that mesh with the internal gear ring 33.

[0044] Specifically, refer to Figures 1 to 3 and Figure 6 The top surface of the second connecting plate 4 is provided with a drive motor 41. The bottom end of the output shaft of the drive motor 41 is provided with a drive bevel gear 411. The middle section of the transmission shaft 43 is provided with a driven bevel gear 431 that meshes with the drive bevel gear 411. Through the setting of the transmission shaft 43, the output shaft of the drive motor 41 drives the drive bevel gear 411 to rotate. Thus, through the meshing and matching effect, the driven bevel gear 431 is driven to rotate, so that the transmission gear 432 drives the internal gear ring 33 to rotate, thereby enabling the two rotating frames 3 to rotate at the same speed and in the same direction.

[0045] Other undescribed structures are described in Example 1.

[0046] Working principle: In this invention, two cables to be welded are inserted into the opposing spur gears 6. Then, according to the rotation of the rotating frame 3, the ends of the two cables come into contact with the two sides of the wire stop plate 21 respectively. As the rotating frame 3 continues to rotate, the spur gear 6 enters the inner groove 202. At this time, the anti-rotation plate 703 and the second ring frame 4204 are in sliding contact, so that the spur gear 6 cannot rotate. Under the limiting action of the compression arc plate 203, the second clamping plate 702 is brought close to the first clamping plate 701. The return spring 707 will generate elastic deformation, so that the two ends of the first clamping plate 701 and the second clamping plate 702 come into contact. Thus, the first clamping plate 701 and the second clamping plate 702 complete the clamping operation of the cables, and fix the distance between the two cables.

[0047] When the spur gear 6 and the tooth 4203 begin to mesh, the contact between the anti-rotation plate 703 and the first ring frame 4202 is released. As the rotating frame 3 rotates, the spur gear 6 can rotate, and at the same time, the welding machine 302 is turned on to weld the ends of the two cables. Utilizing the rotation of the spur gear 6 and the clamping action of the wire clamping mechanism 7, the cable can rotate on its own, allowing the welding machine 302 to perform 360-degree welding on the cable. When the cable diameter is large, the welding effect of the cable can be improved, and there is no need to manually adjust the welding position of the cable.

[0048] When the clamping mechanism 7 drives the cable to rotate, the limiting plate 5 can limit the relative position between the first clamping plate 701 and the second clamping plate 702, preventing changes in the relative position between the first clamping plate 701 and the second clamping plate 702 from affecting the clamping of the cable. After the cable is welded, the cable also completes a 360-degree rotation. Then, the spur gear 6 will rotate out from the other end of the inner groove 202, and the synchronous anti-rotation plate 703 will make a limiting sliding contact with the first ring frame 4202, so that the spur gear 6 will no longer rotate. At the same time, without the constraint and pushing action of the pressing arc plate 203, the elastic deformation of the return spring 707 of the second clamping plate 702 will be restored, so that the clamping of the cable by the second clamping plate 702 and the first clamping plate 701 is released. Then the welded cable is pulled out, and the clamping operation of the next set of cables can be performed.

[0049] The control method of this invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
