Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a double wire feeder. Background Art

[0002] A double wire feeder is a device widely used in the field of automated welding. It can control the supply of two welding wires through two wire feeding assemblies. The function of the wire pressing wheel in the wire feeding assembly is to press the welding wire tightly against the wire feeding wheel, ensuring that the welding wire can pass through the wire feeding mechanism smoothly and continuously, thereby achieving uniform wire feeding. Double wire welding is very suitable for automated and robotic welding applications, and can improve the efficiency and stability of automated production lines. Therefore, the requirements for the double wire feeding rate are relatively high.

[0003] At present, the existing double-wire wire feeders mostly use two motors to control the wire feeding assembly to feed the wire. There is a rate error in the process of synchronous feeding of the welding wire, and the existing wire pressing wheel can only be used for one specification of welding wire. If the welding operation requires the use of multiple specifications of welding wire, the wire pressing wheel needs to be replaced, which increases production costs.

[0004] Therefore, the applicant provides a dual wire feeder to solve the problems raised in the above background technology. Utility Model Content

The two groups of wire feeding assemblies are controlled by a single double-output shaft motor, and the double-output shaft motor synchronously drives the two groups of wire feeding assemblies to deliver welding wires of different specifications.

[0008] A further improvement of the technical solution of the present utility model is that the protrusion on the first latch shaft of the first driven wheel is adapted to pass through the first thread pressing wheel, and the protrusion on the second latch shaft of the second driven wheel is adapted to pass through the second thread pressing wheel.

[0009] A further improvement of the technical solution of the present utility model is that: the circumferential surface of the first wire pressing wheel is provided with first wire pressing grooves and second wire pressing grooves of different specifications, and the circumferential surface of the second wire pressing wheel is a smooth curved surface.

[0010] A further improvement of the technical solution of the present utility model is that locking rods are provided on both sides of the wire feeding frame, and movable plates respectively connected to the second driven wheels are symmetrically provided on the top of the wire feeding frame, and locking grooves are provided on the outer ends of the movable plates, which are used to engage the locking rods.

[0011] A further improvement of the technical solution of the present utility model is that a locking regulating cap is provided at the top end of the locking rod.

[0012] A further improvement of the technical solution of the present utility model is that a welding wire guide inlet pipe and a welding wire guide outlet pipe are sequentially provided on the side surface of the wire feeding frame along the radial direction of the wire feeding disc.

[0013] A further improvement of the technical solution of the present utility model is that a wire outlet hole is provided at a position of the chassis corresponding to the welding wire guide outlet pipe.

[0014] A further improvement of the technical solution of the present invention is that: an inner box with an inclined surface structure is provided on the upper chassis of the wire feeding assembly, and a touch display screen is provided on the inclined surface.

[0015] By adopting the above technical solution, the utility model has the following beneficial effects:

[0016] 1. The utility model provides a dual-wire feeder, which is equipped with a dual-output shaft motor so that the motor output shaft of a single dual-output shaft motor synchronously controls two sets of wire feeding assemblies. In dual-wire synchronous welding, compared with the existing two single-output shaft motors that control the wire feeding assemblies to feed wires separately, the utility model can compensate for the synchronization rate, accurately control the wire feeding speed of the two welding wires, ensure the synchronization of the welding process, and improve the welding efficiency and weld quality.

[0017] 2. The utility model provides a double wire feeder, in which the first driven wheel is symmetrically meshed on both sides of the driving wheel, and the second driven wheels are respectively meshed above the two first driven wheels, so that the first driven wheel and the second driven wheel are meshed and moved synchronously to ensure the synchronous feeding of the welding wire.

[0018] 3. The utility model provides a double wire feeder, in which a first wire pressing wheel is provided on the first pin shaft, and a second wire pressing wheel is provided on the second pin shaft, so that the first wire pressing wheel and the second wire pressing wheel respectively rotate synchronously with the first driven wheel and the second driven wheel, which is beneficial to uniformly compressing and correcting the welding wire.

[0019] 4. The utility model provides a double wire feeder, in which the circumferential surface of the first wire pressing wheel is provided with a first wire pressing groove and a second wire pressing groove of different specifications, so that the first wire pressing wheel is suitable for two welding wires of different specifications. During the specific use of the first wire pressing wheel, the first wire pressing wheel can be installed on the first pin shaft in the forward or reverse direction, and the distances from the first wire pressing groove and the second wire pressing groove to the edge of the first wire pressing wheel are equal. Therefore, the first wire pressing wheel can ensure the linear feeding of the welding wire regardless of whether the first wire pressing groove or the second wire pressing groove is used. The circumferential surface of the second wire pressing wheel is a smooth curved surface, which can cooperate with the first wire pressing wheel to compress and correct welding wires of different specifications.

[0020] 5. The utility model provides a double wire feeder, which is engaged into the locking groove of the movable plate through a locking rod, wherein a locking adjustment cap is provided at the top end of the locking rod. By rotating the locking adjustment cap, the outer end of the movable plate is pressed down to adjust the locking degree. Since the movable plate is connected to the second driven wheel, and the second driven wheel is connected to the second wire pressing wheel, the position of the second wire pressing wheel can be adjusted in a small range, thereby adjusting the compression degree of the welding wire.

[0021] 6. The utility model provides a double wire feeder, in which a wire guide inlet tube and a wire guide outlet tube are sequentially arranged along the radial direction of the wire feed disk on the side of the wire feed frame, which is beneficial to the limited transportation of the welding wire. The horizontal tangents of the wire guide inlet tube, the wire guide outlet tube and the first wire pressing groove are located on the same horizontal line, which is also beneficial to the straightening of the welding wire.

[0035] The present invention will be further explained below in conjunction with specific implementation methods.

[0036] like Figure 1-8 As shown, the present embodiment provides a dual-wire feeding machine, comprising a wire feeding reel 2 arranged inside a chassis 1, a dual-output shaft motor 3 being provided on one radial side of the wire feeding reel 2, two groups of wire feeding assemblies 4 being symmetrically adapted on both sides of the dual-output shaft motor 3, the two groups of wire feeding assemblies 4 being controlled by a single dual-output shaft motor 3, and the dual-output shaft motor 3 synchronously drives the two groups of wire feeding assemblies 4 to deliver welding wires of different specifications; by providing the dual-output shaft motor 3, in dual-wire synchronous welding, compared with the existing two single-output shaft motors that separately control the wire feeding assemblies 4 for wire feeding, the synchronization rate can be compensated, the wire feeding speed of the two welding wires can be accurately controlled, the synchronization of the welding process can be ensured, and the welding efficiency and weld quality can be improved.

[0037] like Figure 3-8 As shown, in this embodiment, the wire feeding assembly 4 includes a wire feeding frame 401, and the outer side wall of the wire feeding frame 401 is penetrated by a motor output shaft 31, and the protrusion on the motor output shaft 31 is adapted to penetrate the driving wheel 402, so that the driving wheel 402 rotates synchronously with the motor output shaft 31, and the first driven wheels 403 are symmetrically meshed on both sides of the driving wheel 402, and the top height of the two first driven wheels 403 is greater than the top height of the driving wheel 402. The second driven wheels 404 are respectively meshed above the two first driven wheels 403, and the two second driven wheels 404 are symmetrically arranged about the driving wheel 402; therefore, the driving wheel 402 drives the two first driving wheels 402 to rotate synchronously in the same direction, and the two first driven wheels 403 respectively drive the two second driven wheels 404 to rotate synchronously in the same direction, thereby ensuring the synchronous feeding of the welding wire. The protrusion on the first latch shaft 405 of the first driven wheel 403 is adapted to pass through the first wire pressing wheel 407, and the protrusion on the second latch shaft 406 of the second driven wheel 404 is adapted to pass through the second wire pressing wheel 408. The protrusion plays a snapping role, so that the first wire pressing wheel 407 and the second wire pressing wheel 408 respectively follow the first driven wheel 403 and the second driven wheel 404 to rotate synchronously in the same direction, which is beneficial to uniformly compressing and correcting the welding wire. The circumferential surface of the first wire pressing wheel 407 is provided with a first wire pressing groove 409 and a second wire pressing groove 410 of different specifications, so that the first wire pressing wheel 407 is suitable for two welding wires of different specifications. During the specific use of the first wire pressing wheel 407, the first wire pressing wheel 407 can be installed on the first latch shaft 405 in the forward or reverse direction, and the first wire pressing groove 409 and the second wire pressing groove 410 are at the same distance from the edge of the first wire pressing wheel 407. Therefore, the first wire pressing wheel 407 can ensure the linear transportation of the welding wire regardless of whether the first wire pressing groove 409 or the second wire pressing groove 410 is used. The circumferential surface of the second wire pressing wheel 408 is a smooth curved surface, which can cooperate with the first wire pressing wheel 407 to compress and correct welding wires of different specifications.

[0038] like Figure 2-6As shown, in this embodiment, a wire guide inlet tube 9 and a wire guide outlet tube 10 are sequentially provided on the side of the wire feeding frame 401 along the radial direction of the wire feeding disk 2, and a wire outlet hole 11 is opened at the position of the wire guide outlet tube 10 corresponding to the chassis 1, which is beneficial to limit the conveying of the welding wire. The horizontal tangents of the wire guide inlet tube 9, the wire guide outlet tube 10 and the first wire pressing groove 409 are located on the same horizontal line, which is also beneficial to straightening the welding wire during the conveying process.

[0039] like Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 As shown, in this embodiment, locking rods 5 are provided on both sides of the wire feeding frame 401, and movable plates 8 connected to the second driven wheel 404 are symmetrically provided on the top of the wire feeding frame 401. The movable plate 8 can rotate around the connection with the wire feeding frame 401, and the outer end of the movable plate 8 is provided with a locking groove 6, which is used to engage the locking rod 5, and the top of the locking rod 5 is provided with a locking adjustment cap 7; the locking rod 5 is engaged with the locking groove 6 of the movable plate 8, and the locking adjustment cap 7 is rotated to press down the outer end of the movable plate 8 to adjust the locking degree. Since the movable plate 8 is connected to the second driven wheel 404, and the second driven wheel 404 is connected to the second wire pressing wheel 408, the position of the second wire pressing wheel 408 can be adjusted in a small range, thereby adjusting the compression degree of the welding wire.

[0040] like Figure 1-2 As shown, in this embodiment, the upper chassis 1 of the wire feeding assembly 4 is provided with an inner box 12 with an inclined structure, and a touch screen 13 is provided at the inclined surface. The dual wire feeder is connected to an external power supply, which is electrically connected to the touch screen 13 and the dual-output shaft motor 3, and the operation of the dual-output shaft motor 3 is controlled by the touch screen 13.

[0041] The working principle of the technical solution provided by the utility model is as follows:

[0042] When the user is in use, the user loosens the locking adjustment cap 7 and swings the locking rod 5 outward to make the locking rod 5 leave the locking groove 6, loosening the restraint on the movable plate 8. The movable plate 8 rotates upward around the connection with the wire feeding frame 401, so that the first wire pressing wheel 407 and the second wire pressing wheel 408 are separated, making it easier for the user to insert the welding wire. The circumferential surface of the first wire pressing wheel 407 is provided with a first wire pressing groove 409 and a second wire pressing groove 410 of different specifications, so that the first wire pressing wheel 407 is suitable for two welding wires of different specifications. During the specific use of the first wire pressing wheel 407, the first wire pressing wheel 407 can be installed on the first latch shaft 405 in the forward or reverse direction, and the first wire pressing groove 409 and the second wire pressing groove 410 are at the same distance from the edge of the first wire pressing wheel 407. Therefore, the first wire pressing wheel 407 can ensure the straight line feeding of the welding wire regardless of whether the first wire pressing groove 409 or the second wire pressing groove 410 is used. After selecting the appropriate first wire pressing groove 409 or second wire pressing groove 410 according to the specifications of the welding wire, the user can feed the welding wire from the feeding The wire is manually pulled out from the wire reel and passes through the welding wire guide inlet tube 9, the first wire pressing groove 409 of the two first driven wheels 403 and the wire outlet hole 11 in turn. Since the horizontal tangent of the welding wire guide inlet tube 9, the first wire pressing groove 409 and the welding wire guide outlet tube 10 are located on the same horizontal line, the welding wire can be straightened; then the locking rod 5 is engaged with the locking groove 6 of the movable plate 8, the locking adjustment cap 7 is rotated, and the outer end of the movable plate 8 is pressed down to adjust the locking degree. Since the movable plate 8 is connected to the second driven wheel 404, and the second driven wheel 404 is connected to the second wire pressing wheel 408, the position of the second wire pressing wheel 408 can be adjusted in a small range, thereby adjusting the compression degree of the welding wire.

[0043] The user controls the start of the dual-output shaft motor 3 through the touch display screen 13, and the driving wheel 402 that is adapted to pass through the convex block on the motor output shaft 31 rotates synchronously with the motor output shaft 31, and the first driven wheels 403 are symmetrically arranged on both sides of the driving wheel 402, and the second driven wheels 404 are respectively arranged to be meshed directly above the two first driven wheels 403; therefore, the driving wheels 402 on both sides of the dual output shaft respectively drive the two first driving wheels 402 to rotate synchronously in the same direction, and the two first driven wheels 403 respectively drive the two second driven wheels 404 to rotate synchronously in the same direction, thereby realizing the synchronous feeding of the welding wire.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
