Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of friction welding fixtures, in particular to a two-in-one friction welding fixture for a busbar. Background Art
[0002] Busbar is the name of the conductive material on power distribution equipment. It is usually made of flat copper (equivalent to conductive wire) without an insulating layer. The outside is painted with color paint indicating the phase sequence or covered with sleeves of corresponding colors. It is mainly used in scenarios where large currents need to be transmitted, such as connecting indoor transformers to distribution cabinets, and connecting the main power switch to each branch switch.
[0003] Friction stir welding refers to the use of high-speed rotating stirring needles and the workpieces to generate heat to plasticize the workpieces. When the stirring needle moves forward along the workpiece, the plasticized material flows from the front of the stirring needle to the back under the action of the rotating friction of the stirring needle, and forms a dense friction stir welding seam under the extrusion of the stirring needle. It can be used to weld busbars without forming welds that affect current transmission.
[0004] During the welding process of the copper busbar, it is sometimes necessary to weld the copper busbar into a composite copper busbar with a certain angle. At this time, two people are required to operate at the same time, one to fix the copper busbar and the other to weld it. This not only has low work efficiency, but also causes deviations in the processing position due to human factors, resulting in the angle of the copper busbar being welded not meeting the use standards.
[0005] However, the existing clamps have a single structure and cannot clamp the busbars at multiple points, resulting in poor clamping effect, easy loosening, and inconvenience for subsequent friction welding processing, and low practicality. In particular, busbar welding may also produce special-shaped and strip-shaped busbars, which cannot be clamped and fixed well by the existing clamps, affecting the welding effect and work efficiency of friction welding.

DETAILED DESCRIPTION
[0034] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0035] See also Figures 1 to 7 In an embodiment of the utility model, a two-in-one friction welding fixture for busbars includes a first fixture 10 and a second fixture 40 arranged in sequence along the X-axis transversely, wherein the first fixture 10 is used to clamp and fix two special-shaped busbars 71 that need to be welded into a right-angle shape, and the second fixture 40 is used to clamp and fix a long busbar 72 that moves along the X-axis toward the first fixture 10; the first fixture 10 is provided with a first supporting roller 11, and the first supporting roller 11 is fixedly connected to one end of the first fixture 10 away from the second fixture 40, and is used to provide auxiliary support for one end of the long busbar 72 that is welded on the second fixture 40 and moves toward the first fixture 10.
[0036] Specifically, due to the different installation scenarios of busbars, the shapes and welding angles of the required welding wires are also different, so different welding fixtures are needed to clamp and fix them. Traditional fixtures have poor fixing effects and are prone to loosening or deviation, which affects the welding quality and increases the resistance of the final busbar, which is not conducive to transmitting large currents. In addition, the production and welding of different wires requires the replacement of fixtures, which also affects production efficiency.
[0037] Therefore, a two-in-one clamp can be provided so that it can perform right-angle welding on the special-shaped wire array 71 and perform progressive lengthening welding on the long wire array 72 to meet the needs of actual installation scenarios. The first support roller 11 provided on the first clamp 10 can also be used to support the long wire array 72 after lengthening welding so that it will not be bent by its own gravity, and it is also convenient for unloading after welding is completed.
[0038] Secondly, the two-in-one fixture can also be uniformly fixedly installed on the welding platform of the external friction welding equipment, so that it can perform welding operations on the special-shaped wire row 71 and the long wire row 72 respectively, saving the time of adjusting the fixture and further improving production efficiency.
[0039] like Figure 2 and Figure 3 As shown, preferably, the first fixture 10 is provided with a first base 12 and a first table 13, the first base 12 is used to fix the first fixture 10 on the welding platform of the external friction welding equipment, the first table 13 is fixedly connected to the first base 12 through the first column 14, the upper part of the first table 13 is provided with a first limiting plate 15, a second limiting plate 16 and a third limiting plate 17, the first limiting plate 15 is provided with an L-shaped right-angle side, so that the two special-shaped line rows 71 to be welded are respectively abutted against the two right-angle sides of the L-shape, so that the welding parts of the two special-shaped line rows 71 are abutted against each other, and the formed weld is located on the bisector of the right angle; the second limiting plate 16 and the third limiting plate 17 are respectively fixedly connected to the two ends of the first table 13, and are used to respectively abut the two special-shaped line rows 71.
[0040] Specifically, since one end of the two special-shaped wire rows 71 needs to be welded to form a right angle, the first limiting plate 15 can be set to an L-shaped right angle shape, so that the sides of the two special-shaped wire rows 71 can be sequentially abutted against the first limiting plate 15 to form an accurate right angle shape. At the same time, since the length of the special-shaped wire row 71 is relatively long, the second limiting plate 16 and the third limiting plate 17 can be respectively set in the long side direction thereof, so that the extended part can also accurately find the position to avoid affecting the welding end.
[0041] like Figure 3 and Figure 4As shown, preferably, the first fixture 10 is further provided with a clamping assembly 20, and the clamping assembly 20 is used to clamp the two special-shaped wire rows 71 against the first limit plate 15 respectively. The clamping assembly 20 is provided with a clamping rail 21, a clamping slider 22, a clamping block 23 and a clamping cylinder 24, wherein the clamping rail 21 is fixed to the upper part of the first base plate, the clamping cylinder 24 is fixed to the lower part of the first platen 13, the clamping slider 22 is slidably connected to the clamping rail 21, the clamping block 23 is fixed to the clamping slider 22, and is transmission-connected to the piston rod of the clamping cylinder 24, so that the clamping cylinder 24 is operated, and the clamping block 23 is driven to move toward the first limit plate 15, thereby clamping the special-shaped wire row 71 against the first limit plate 15.
[0042] Specifically, because the special-shaped wire row 71 is relatively long, in order to further firmly clamp and fix its welding end, a clamping assembly 20 can be provided, and the thrust of the clamping cylinder 24 is used to firmly push the clamping block 23 against the side of the special-shaped wire row 71 so that it can be pressed against the first limit plate 15. It can be understood that Figure 4 As shown, since the abutment block abuts against the shaped wire row 71 from the Y-axis direction, the shape of the abutment block 23 also needs to be set to match the side of the shaped wire row 71 so that it can be accurately abutted against the limit plate. In addition, since two shaped wire rows 71 need to be placed at the first limit plate 15, two sets of abutment components 20 can be set, and two sets of abutment blocks 23 are used to perform abutment operations on the two shaped wire rows 71 respectively.
[0043] like Figure 2 and Figure 3 As shown, preferably, the first clamp 10 is also provided with a top pressure block 30 and a top pressure cylinder 32, the top pressure cylinder 32 is fixed to the first base plate, the top pressure block 30 is arranged on the upper part of the first platform 13, and is fixed to the piston rod of the top pressure cylinder 32, and is used to abut the two special-shaped line rows 71 from top to bottom, so that they are stably fixed on the first platform 13.
[0044] Specifically, the top pressure block 30 may be provided with two arms 31, so that the two arms 31 respectively abut against the two special-shaped wire rows 71. Preferably, three top pressure cylinders 32 are provided, one of which is provided at the positions corresponding to the two arms 31, and another is provided in the middle of the two arms 31. The installation positions of the three top pressure cylinders 32 are roughly set to a triangle, and the stability of the triangle is used to improve the stability of the top pressure cylinder 32 driving the top pressure block 30.
[0045] like Figure 2 and Figure 3As shown, preferably, the first clamp 10 is also provided with a first support plate 33, a second support plate 34, a second support roller 35 and a third support roller 36. The first support plate 33 and the second support plate 34 are respectively fixed to the two ends of the first substrate, and are used to support the two special-shaped wire rows 71 above the first substrate; the second support roller 35 and the third support roller 36 are respectively installed on the external ground corresponding to the non-welded end of the two special-shaped wire rows 71, and are used to support the non-welded end of the two special-shaped wire rows 71 respectively.
[0046] Specifically, similarly, since the length of the special-shaped wire row 71 is relatively long, in order not to affect the stability of one end of the welding, a corresponding support plate and support roller may be provided to support and fix the other longer extended end thereof.
[0047] like Figures 5 to 7 As shown, preferably, the second fixture 40 is provided with a second base 41 and a second platform 42, the second base 41 is used to fix the second fixture 40 on the welding platform of the external friction welding equipment, and the second platform 42 is fixedly connected to the second base 41 through a second platform column 43; a guide column 44 and a guide plate 45 are provided on one side of the upper part of the second platform 42 close to the long side direction of the long line row 72, and the guide plate 45 is fixedly connected to the second platform 42 through the guide column 44, and the guide plate 45 is used to abut against one side of the long line row 72, so that the long line row 72 moves forward along the guide plate 45. The second fixture 40 is also provided with a third support plate 64, which is fixed to the external ground and is used to support the long line row 72 that has not yet entered the second fixture 40.
[0048] Specifically, since the long line array 72 needs to weld multiple units in sequence, a guide plate 45 needs to be provided so that when the long line array 72 moves toward the first fixture 10 after welding one unit, the side of the long side can rely on the guide plate 45, so that the guide plate 45 limits and guides the long line array 72, thereby ensuring that the moving direction of the long line array 72 will not deviate. In addition, a support plate can also be provided to support one end of the long line array 72, so as to facilitate the operation of workers and improve production efficiency.
[0049] like Figure 6 and Figure 7 As shown, preferably, the second clamp 40 is also provided with a first pressure plate 50, a first support 51 and a first cylinder 52, the first cylinder 52 is fixedly connected to the second base 41, the first support 51 is fixedly connected to the first cylinder 52, the middle part of the first pressure plate 50 is rotatably connected to the first support 51, one end of the first pressure plate 50 is rotatably connected to the piston rod of the first cylinder 52, and the other end thereof performs a pressing operation on the long line row 72.
[0050] Specifically, the first cylinder 52 can be fixed to the second base 41 through the second column 43. In addition, two corresponding sets of first pressing plates 50 can be provided to press the long line 72. When the long line 72 needs to move forward, the first cylinder 52 drives the piston rod to move downward, so that the first pressing plate 50 rotates upward, lifts a certain angle, and releases the pressing of the long line 72.
[0051] like Figure 6 and Figure 7 As shown, preferably, the second clamp 40 is also provided with a second pressure plate 60, a second support 61, a second cylinder 62 and a second wedge block 63. The second cylinder 62 and the second support 61 are respectively fixed to the second base 41. The second wedge block 63 is slidably connected to the second support 61 and forms a transmission connection with the piston rod of the second cylinder 62. One end of the second pressure plate 60 abuts against the long line row 72, and the other end thereof forms a slidable mortise and tenon connection with the second wedge block 63, so that the second cylinder 62 is operated to drive the second wedge block 63 to move up and down, thereby driving the second pressure plate 60 to move forward or backward toward the long line row 72.
[0052] Specifically, the second cylinder 62 and the second support 61 can be fixed to the second base 41 through the second column 43. Similarly, two sets of second pressing plates 60 can be set to abut and press the long line 72. In order to better position the long line 72, a movable stop bar 73 can be installed on the long line 72, and the movable stop bar 73 can be adjusted according to the welding position, length and other parameters. When the second pressing plate 60 abuts and presses the long line 72, it can also block the movable stop bar 73, so that the long line 72 stops moving and is fixed at a preset position, so as to facilitate welding of its preset weld.
[0053] Secondly, the slidable mortise and tenon connection formed between the second pressing plate 60 and the second wedge block 63 can be a matching structure of a slide groove and a slide rail in the prior art, so that the vertical movement of the second wedge block 63 can drive the lateral movement of the second pressing plate 60, thereby abutting and pressing the long line row 72. The second pressing plate 60 can be set to have a relatively thin front end and a relatively thick rear end, so that when it moves laterally toward the long line row 72, it can also form a pressing operation on the long line row 72.
[0054] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
