Description

Technical Field

[0001] The utility model relates to the technical field of fuse welding, and more specifically to a butt welding device used for fuse welding. Background Art

[0002] like Figure 1 The fuses 200 shown need to be spliced ​​and welded together in pairs to meet the requirements of fuses of different lengths and sizes due to different usage environment requirements.

[0003] The existing welding method is to manually overlap one end of two fuses 200, place them on a butt welding machine, and use the upper electrode to move closer to the lower electrode and then abut against the overlapping part a to perform butt welding on the overlapping part of the two fuses 200 to achieve the connection of the two fuses 200. Since the fuses 200 are placed manually, the pick-up and place operations need to be repeated continuously, and only two fuses 200 can be welded each time, resulting in high work intensity and low production efficiency.

[0004] To solve the above problems, the applicant has developed a Chinese utility model patent with Chinese application number CN202320802407.0, which discloses a butt welding device for fuse welding, the butt welding device comprising a butt welding jig and a welding head suspended above the butt welding jig; the butt welding jig comprises a placement plate, a row of placement areas arranged in a row of a plurality of longitudinal placement areas is provided on the placement plate, and a welding long hole is provided on the placement plate for the placement area to connect the middle of each placement area, and a lower electrode is provided in the welding long hole; the two sides of each placement area are respectively used to place a fuse, so that the overlapping parts of the two fuses are located above the welding long hole and contact the lower electrode; an upper electrode is provided at the lower end of the welding head, and can reciprocate relative to each placement area along the arrangement direction of the placement area, and can reciprocate vertically to move close to or away from the fuse. When the equipment is running, the upper electrode can move downward close to the fuse and reciprocate up and down to intermittently conduct with the lower electrode in the welding slot through the overlapping parts of the two fuses, thereby realizing the butt welding operation on the fuse.

[0005] In the above-mentioned resistance welding equipment, the structure of the resistance welding jig is relatively complex. The lower electrode needs to be fixed in the welding long hole of the placement plate. Since the electrode needs to be frequently troubleshot and replaced, such an installation structure is inconvenient for replacing the lower electrode. In addition, when resistance welding is performed between the upper electrode and the lower electrode, the upper electrode moves up and down reciprocally. When the pressure applied by the upper electrode downward is relatively large, a large impact force is generated on the lower electrode, which will easily cause the lower electrode to be damaged. Therefore, the lower electrode is a vulnerable part and needs to be replaced frequently. As mentioned above, the lower electrode is fixed in the welding long hole, and the installation structure is relatively cumbersome, making disassembly and replacement inconvenient. Moreover, after placing the fuse in the placement plate and then installing the fixing parts, the fixing parts include a pressing plate and a locking part, so as to fix the fuse. Such a structural design makes the operation steps for fixing the fuse more cumbersome and reduces the work efficiency. Utility Model Content

[0036] In order to further explain the technical solution of the present invention, the present invention will be elaborated in detail below through specific embodiments.

[0037] Refer to Figure 2 、 Figure 3 and Figure 7 As shown, the present invention discloses a butt welding device for fuse body welding, which is arranged on a machine platform 600 and includes: a butt welding fixture 100 and a welding head 3 suspended above the butt welding fixture 100. Among them, the butt welding fixture 100 includes a placement plate 1. The placement plate 1 is provided with a placement area 11 formed by a plurality of placement areas 111 arranged longitudinally in a column. And a welding long hole 12 is provided on the placement plate 1 corresponding to the placement area 11 to communicate with the middle parts of the respective placement areas 111. Both sides of each placement area 111 are respectively used to place a fuse body 200, so that the overlapping part a of two fuse bodies 200 is located above the welding long hole 12; the lower end of the welding head 3 is provided with an upper electrode 31, and can reciprocate relative to each placement area 111 along the arrangement direction of the placement areas 111, and can reciprocate vertically up and down to approach or move away from the fuse body 200.

[0038] In the present invention, it further includes a lower electrode 47 and a lifting assembly 400 arranged below the placement area 11 for lifting the lower electrode 47. When the lower electrode 47 is lifted by the lifting assembly 400, it is placed in the welding long hole 12 and contacts the overlapping part a of the fuse bodies 200 on the left and right sides. After being lifted, the lower electrode 47 is supported below the overlapping part a of two fuse bodies. The upper electrode 31 can be intermittently conducted with the lower electrode 47 in the welding long hole 12 across the overlapping part a of two fuse bodies to realize the butt welding operation. Since the lower electrode 47 and the upper butt welding fixture 100 above are of a split structure and are only lifted into the welding long hole 12 by the lifting assembly 400 when butt welding is required, the lower electrode 47 is arranged at the top of the lifting mechanism and can be directly replaced when replacement is needed, which simplifies the disassembly and assembly structure of the lower electrode, is convenient for disassembly and assembly, and is convenient for the staff to maintain.

[0039] In this embodiment, the welding head 3 is connected to a vertical linear module 33 to reciprocate vertically. The vertical linear module 33 is arranged on a horizontal linear module 32 to enable the welding head 3 to also reciprocate horizontally. The resistance welding fixture 100 is connected to a longitudinal linear module 13 and can move longitudinally. The electrical wire connector of the external electrical wire (not shown in the figure) is arranged on one side of the horizontal linear module 32 so that the displacement of the welding head 3 is not interfered by the external electrical wire. And in this way, the electrical conduction between the upper electrode 31 and the lower electrode 47 is realized. The polarity setting of the electrical conduction of the upper and lower electrodes 47 is the prior art and will not be elaborated here.

[0040] The machine table 600 can be provided with at least two resistance welding fixtures 100. When the equipment is working, welding can be carried out in batches, improving the degree of automation and saving manpower. Refer to Figure 4 , on the machine table 600 in this embodiment, there are two resistance welding fixtures 100, which are arranged side by side horizontally. Each resistance welding fixture 100 has two rows of placement areas 11, and each placement area 11 corresponds to a set of lifting components 400 and a lower electrode 47 respectively. The resistance welding fixture 100 further includes a welding plate 14 located below the placement plate 1 and a cover plate 15 located above the placement plate 1, so that the welding long holes 12 penetrate through the cover plate 15, the placement plate 1, and the welding plate 14 up and down, that is, the welding long holes 12 that are parallel and penetrate up and down are formed in the placement plate 1, the welding plate 14, and the cover plate 15 at the same time.

[0041] Combined with Figures 4 to 7 As shown, the lifting component 400 can include a power unit and a lifting unit driven by the power unit to lift and lower in the vertical direction. The lower electrode 47 is fixed on the lifting unit, and the lower electrode 47 realizes automatic lifting and lowering through the lifting unit. In this embodiment, the lifting unit includes a horizontal displacement member 42 and a vertical displacement member. A pushing surface 421 with a slope surface is formed on the upper surface of the horizontal displacement member 42. The vertical displacement member is placed and supported on the pushing surface 421 of the horizontal displacement member 42, and the lower electrode 47 is fixed at the upper end of the vertical displacement member. The power unit can drive the horizontal displacement member 42 to displace in the horizontal direction. The reciprocating horizontal displacement member 42 can drive the vertical displacement member to realize lifting and lowering, forming a height change, and the vertical displacement member can be stable at the highest point of the horizontal displacement member 42 when the upper and lower electrodes are conductively welded.

[0042] In this embodiment, guide blocks 423 are provided on both sides below the horizontal displacement member 42. The power unit drives the horizontal displacement member 42 to linearly slide between the guide blocks 423, which can further limit the displacement path of the horizontal displacement member 42 to improve the accuracy of the equipment.

[0043] In this embodiment, the horizontal displacement member 42 is also provided with an upper platform 422 extending outside the highest point of the slope of the push surface 421, which can stably support the vertical displacement member. When the lower electrode 47 is lifted up by the lifting assembly 400 and placed in the welding long hole 12 for conductive butt welding, the vertical displacement member can be located on the upper platform 422 to achieve stable support.

[0044] In this embodiment, the power unit is a first cylinder 41, which is mounted on a mounting plate 4 provided on a machine 600. The mounting plate 4 has a horizontal section extending in the horizontal direction and two guide blocks 423 installed opposite to each other are provided on the horizontal section. The horizontal displacement member 42 is provided between the two guide blocks 423 and can slide on the horizontal section. A piston rod 411 for horizontal movement is provided in the first cylinder 41. One end of the piston rod 411 passes through the first cylinder 41 and is connected to the horizontal displacement member 42 through the connecting block 412, thereby driving the horizontal displacement member 42 to horizontally displace between the two guide blocks 423. The vertical displacement member may include a bearing 43 installed in a lifting frame that can move up and down. The bearing 43 slides on the push surface 421 of the horizontal displacement member 42, and the lower electrode 47 is provided above the lifting frame. Specifically, the lifting frame includes a lifting plate 441, a bearing connection block 431 disposed on the lower surface of the lifting plate 441, and a rotating shaft 432 passing through the bearing connection block 431, and the bearing 43 is connected to the rotating shaft 432. Among them, the four corners of the lifting plate 441 can be respectively provided with through holes, and the through holes are respectively provided on four columns 442, and the lower ends of the four columns 442 are connected to the mounting plate 4, whereby the lifting plate 441 can be supported by the bearing 43 and slide up and down relative to the columns 442. The two ends of the rotating shaft 432 respectively pass through the two sides of the bearing connection block 431, and the bearing 43 is connected to the rotating shaft 432 and slides on the push surface 421 of the horizontal displacement member 42. The electrode connection block 46 is disposed on the upper surface of the lifting plate 441, and the lower electrode 47 is disposed on the electrode connection block 46. An insulating block 45 is also disposed between the electrode connection block 46 and the lifting plate 441. The push surface 421 of the horizontal displacement member 42 forms a slope with an arc, and correspondingly, the bearing 43 can roll up and down smoothly on the slope. An upper platform 422 is also extended from the highest point of the horizontal displacement member 42. When performing butt welding, the bearing 43 stands firmly on the upper platform 422, and when subjected to downward pressure, it will not slide down or deviate directly along the slope, and can support the completion of the butt welding action.

[0045] Further, the lifting frame further includes a tension spring 443 that can pull and lift the lifting plate in the vertical direction. In this embodiment, a pair of symmetric tension springs 443 are provided in the lifting plate 441. The tension springs 443 are vertically arranged. The upper ends of the tension springs 443 are connected to both sides of the lifting plate 441, and the lower ends are fixedly connected to both sides of the mounting plate 4. When the lifting plate 441 is lifted, the tension springs 443 are elastically deformed and stretched. The tension springs 443 can be used for the reset of the lifting plate 4 after lifting. After the butt welding is completed, when the piston rod 411 pushes the horizontal displacement member 42 and the bearing 43 leaves the upper platform 422, the reset elastic force of the tension spring 443 can be used to drive the lifting plate 441 to return to its original position, and at the same time drive the bearing 43 to roll on the surface of the horizontal displacement member 42 and reset along the slope. The tension spring 443 can be used to help the lifting plate 441 reset after lifting, avoiding the situation that when the horizontal displacement member 42 pulls back, the bearing 43 may get stuck in a position and cannot reset smoothly along the slope.

[0046] When using the vertical displacement member with the above lifting structure for butt welding, since the upper electrode 31 and the lower electrode 47 must move towards each other, when the lower electrode 47 is subjected to the downward pressure from the upper electrode 31, it will generate a downward pressure on itself and all the structures below. Therefore, only the vertical pressure is transmitted to the vertical displacement member. Similarly, the horizontal displacement member 42 below the vertical displacement member will only be subjected to the vertical pressure. If a driving member that generates an upward thrust in the vertical direction is used to support the vertical displacement member at this time, it may cause insufficient support force and downward displacement due to the mutual cancellation of forces or excessive downward pressure, and the lower electrode 47 cannot stably perform butt welding with the upper electrode 31. Therefore, in this embodiment, the horizontal displacement member 42 is used as the support for the vertical displacement member. Since the horizontal displacement member 42 can only displace in the horizontal direction between the two guide blocks 423 and has no space to displace in the vertical direction, the horizontal displacement member 42 will not be at risk of being pressed down when subjected to the vertical pressure, so it can stably support the vertical displacement member and prevent the lower electrode 47 from having a tendency to displace downward when facing the downward pressure from the upper electrode 31, resulting in incomplete butt welding.

[0047] When it is necessary to replace the lower electrode 47, only need to disassemble and replace the lower electrode 47 from the electrode connection block 46, and the maintenance process is convenient.

[0048] In order to improve the precision of butt welding and prevent the fuse body 200 from shifting during butt welding, a fixing member 500 is further provided above the placement area 11 in this embodiment. The fixing member 500 includes at least one set of downward pressing components mounted on a cylinder mounting plate 5. The downward pressing component includes a pressing block 52 and at least one second cylinder 53 that can drive the pressing block to move up and down. The second cylinder 53 can drive the pressing block 52 to press against the fuse bodies 200 on both sides of the placement area respectively. In this embodiment, a cylinder mounting plate 5 is correspondingly and horizontally arranged above each butt welding jig 100. A pressing block 52 is respectively arranged between the two placement areas 11 on the lower surface of the cylinder mounting plate 5. Two second cylinders 53 are respectively arranged on the upper surface of the cylinder mounting plate 5 corresponding to each pressing block 52. A first through hole 521 that penetrates up and down is provided in the middle of each pressing block 52 corresponding to the welding long hole 12. The first through hole 521 can form a frustum-shaped through hole with a diameter that decreases from top to bottom. The second cylinder 53 drives the two sides of the pressing block 52 to respectively abut against the fuse bodies 200 on both sides of the placement area 111. A second through hole 51 is also provided on the cylinder mounting plate 5 at the position of the first through hole 521 corresponding to the pressing block 52. The second through hole 51 can form a strip-shaped hole. During butt welding, the upper electrode 31 can sequentially pass through the second through hole 51, the first through hole 521, and the welding long hole 12. The first through hole 521 and the second through hole 51 are vertically corresponding. When the upper electrode deflects during the downward pressing process, the design of the two through holes can form a certain guiding effect in two directions, preventing the electrode from being directly blocked during the downward pressing and unable to form electrical conduction smoothly. When the butt welding device is operating, the second cylinder 53 serves as the power to drive the pressing block 52. First, the pressing block 52 is used to press and fix the fuse bodies 200 on both sides of the placement area 111. At this time, the upper electrode 31 at the lower end of the welding head 3 descends vertically and approaches the fuse body 200, sequentially passes through the second through hole 51 and the first through hole 521, and after being guided by the inner wall of the first through hole 521, accurately descends into the welding long hole 12 to cooperate with the lower electrode 47 for butt welding to improve the welding precision. Through the automatically operated pressing block 52, when the lifting assembly 400 drives the lower electrode 47 to rise during the butt welding operation, it can downwardly press and position the fuse bodies 200 on both sides of the placement area 111 and can cooperate to achieve a reciprocating motion, thereby simplifying the fixing structure in the butt welding jig, improving the degree of automation, and improving the working efficiency.

[0049] The above is only one embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
