Description

Technical Field

[0001] The present invention belongs to the technical field related to welding processing, and more specifically, it is a high-strength aluminum alloy welding device for the production of resonant rods. Background Art

[0002] The welding process of resonant rods requires high-precision welding technology. Usually, laser welding or electron beam welding is the mainstream process. For brittle materials such as metals and ceramics, positioning needs to be achieved through a precision motion platform, and the welding power and scanning speed are controlled to suppress the heat-affected zone and avoid frequency deviation caused by the deformation of the resonant cavity.

[0003] The patent document with the publication number CN216706486U discloses a new type of automatic welding device for a double-section rod body, including a first slider and a bottom plate. A clamping device is arranged above the bottom plate. The base is fixedly connected to the upper surface of the bottom plate. One end of three first support rods is rotatably connected to the surface of the base through a pin shaft. A second slider is slidably connected to the outer wall of the first support rod. The other end of the first support rod is rotatably connected to a roller through a bearing. The outer walls of the three second sliders are rotatably connected to a ring through a pin shaft. The outer wall of the ring is rotatably connected to a first threaded block through a pin shaft. In this new type of automatic welding device for a double-section rod body, through the cooperation among the base, the ring, the first support rod, the second slider, the roller, the square block, the screw rod, the first threaded block and the handle, the handle drives the double-headed stud to rotate, and the double-headed stud drives the first threaded block to move.

[0004] The above device has certain deficiencies when welding resonant rods. The welding of resonant rods has certain requirements for precision. During the welding operation, the ends of the resonant rods need to be coaxially aligned. In the misaligned state, the welding effect of the resonant rods will be affected. The above welding device does not have an auxiliary positioning structure, and it cannot automatically center and align the resonant rods during use, nor can it flexibly adapt to resonant rods of different specifications. Secondly, the welding of resonant rods is circular welding. During the welding operation, the resonant rods need to be rotated and adjusted. The traditional welding device does not have a rotation assistance structure. During the rotation adjustment, the resonant rods are prone to displacement, affecting the welding precision. At the same time, the traditional device cannot flexibly adapt to different types of welding structures and can only be applied to conventional circular welding structures, reducing the flexibility during the welding operation. Summary of the Invention

[0005] The purpose of the present invention is to provide a high-strength aluminum alloy welding device for the production of resonant rods, which can solve the existing problems.

[0006] The problems solved by the present invention are: 1. The welding of the resonant rod has certain requirements for precision. During the welding operation, the ends of the resonant rod need to be coaxially aligned. In the case of misalignment, it will affect the welding effect of the resonant rod. The above welding equipment does not have an auxiliary positioning structure, and it cannot automatically center-align the resonant rod during use, nor can it flexibly adapt to resonant rods of different specifications. Secondly, the welding of the resonant rod is circular welding. During the welding operation, the resonant rod needs to be rotated and adjusted. The traditional welding equipment does not have a rotation assistance structure. When rotating and adjusting, the resonant rod is prone to displacement, affecting its welding precision. At the same time, the traditional equipment cannot flexibly adapt to different types of welding structures and can only be applicable to conventional circular welding structures, reducing the flexibility during the welding operation.

[0007] The object of the present invention can be achieved through the following technical solutions: A high-strength aluminum alloy welding equipment for the production of resonant rods, including a fixed base, a positioning tooling and a welding part. The welding part is arranged on the upper outer surface of the fixed base. The positioning tooling is fixedly installed on the upper end of the fixed base on one side of the welding part. The positioning tooling includes a first bottom plate and a second bottom plate. The first bottom plate is fixedly installed on one side of the second bottom plate. Sliding chucks are movably installed on the upper ends of the first bottom plate and the second bottom plate, and side rotating clamping plates are movably installed on the upper ends of the sliding chucks. The two groups of side rotating clamping plates are symmetrically arranged. A positioning roller is movably installed on the upper end of the side rotating clamping plate, and the side rotating clamping plate and the positioning roller are movably connected through an auxiliary clamping seat.

[0008] As a further technical solution of the present invention, a threaded sliding sleeve is fixedly installed at the middle position of the lower end of the second bottom plate, and a limiting ejector rod is fixedly installed at the middle position of the rear end of the first bottom plate. The overall shape of the limiting ejector rod is an L-shaped structure. The first bottom plate and the second bottom plate are fixed by a rod body. During the welding and fixing operation of the resonant rod, by using the setting of the positioning tooling, it has an adjustable V-shaped limiting and fixing structure, so that the two workpieces are centered and aligned. When the user places the workpiece on the upper parts of the first bottom plate and the second bottom plate, the bottom of the workpiece contacts the two groups of side rotating clamping plates on the first bottom plate and the second bottom plate. Due to the self-gravity of the workpiece, one end of the two groups of side rotating clamping plates tilts upward. The two groups of side rotating clamping plates are in a V-shaped structure and are respectively clamped on both sides of the workpiece. When the two groups of positioning toolings are respectively used for installing the workpiece, the two groups of workpieces are both in a centered state, so that the two groups of workpieces are centered and aligned during welding, avoiding the misalignment of their welds.

[0009] As a further technical solution of the present invention, the two sets of threaded sliding sleeves are driven by a lead screw. A sliding wheel is arranged at the middle position of the lower end of the sliding clamp seat. Chutes for cooperating with the sliding wheel are arranged at the upper ends of the first bottom plate and the second bottom plate. The user can move the first bottom plate and the second bottom plate according to the diameter of the workpiece by using the sliding wheel to cooperate with the chute, so as to adjust the use distance of the rotary clamping plates on the upper sides of the first bottom plate and the second bottom plate, and play a role in adjusting the V-shaped structure size of the side rotary clamping plates. During the welding operation, the lead screw is driven by a motor, so that the lead screw drives the two sets of threaded sliding sleeves, and thus the two positioning jigs move towards each other, so that the workpieces on the two positioning jigs are butted against each other. The setting of the limiting ejector rod plays a role in fixing the tail end of the workpiece after the workpiece is installed.

[0010] As a further technical solution of the present invention, a support block is fixedly installed at the upper end of the sliding clamp seat. The side rotary clamping plate and the positioning roller are movably connected through an auxiliary clamping seat. A positioning slider is installed at the middle position of the lower end of the auxiliary clamping seat. A lower roller is arranged at one end of the side rotary clamping plate. When the side rotary clamping plate rotates obliquely under the action of the workpiece, the positioning roller is stuck on the side of the workpiece, and at the same time the lower roller contacts the bottom of the workpiece to meet the rotational use of the workpiece. Because the workpiece needs to be rotated and adjusted during welding, the positioning roller can play an auxiliary positioning role when the workpiece rotates, avoiding the workpiece falling off the positioning jig. The use position of the positioning roller can be adjusted by using the auxiliary clamping seat, so as to meet the rotational limit of workpieces with different diameters.

[0011] As a further technical solution of the present invention, elastic top plates are arranged on both sides of the positioning slider at the bottom of the auxiliary clamping seat. The auxiliary clamping seat and the elastic top plates are elastically connected through elastic members. By using the elastic top plates to cooperate with the elastic members, the moved auxiliary clamping seat can be fixed, which is convenient for the auxiliary clamping seat to perform adjustment operations at any position.

[0012] A pressure rod is movably installed between the auxiliary clamping seat and the elastic top plate. Roller shafts are arranged at the bottoms of the first bottom plate and the second bottom plate. The user presses the pressure rod, so that the pressure rod can control the movement of the elastic top plate, and the elastic top plate is loosened from the chute. When the pressure rod is released, the elastic member is used to push the elastic top plate, so that the elastic top plate is clamped inside the chute.

[0013] As a further technical solution of the present invention, the welding part includes a moving base and a lifting table. The lifting table is movably installed at the upper end of the moving base, and a welding head is movably installed at the front end of the lifting table. By using the settings of the lifting table and the moving base, the two-way position movement of the welding head can be completed, so that the welding head can complete welding operations of various shapes as shown in Figure 9 in the figure.

[0014] As a further technical solution of the present invention, a lifting seat is provided at the front end of the lifting table, the welding head is installed at the bottom of the lifting seat, and the lifting table and the lifting seat are driven by a cylinder. The cylinder is used to drive the lifting seat, so that the lifting seat drives the welding head to move up and down, thereby adjusting the use height of the welding head.

[0015] As a further technical solution of the present invention, a driving wheel is movably installed in the middle of the moving base, a moving slider is provided at the bottom of the lifting table, and the moving base and the lifting table are driven by a horizontal push rod. The horizontal push rod can be used to drive the lifting table, so that the lifting table moves horizontally on the moving base.

[0016] As a further technical solution of the present invention, a telescopic column is provided at one end of the driving wheel, and a telescopic sleeve is movably sleeved on the outer surface of the telescopic column. The telescopic column and the telescopic sleeve are driven by a threaded rod. An electric motor is provided inside the telescopic sleeve. When performing the rotary welding operation of the workpiece, the electric motor is used to drive the threaded rod to rotate, and the threaded rod is used to drive the telescopic column to move outwards, so that the driving wheel at one end of the telescopic column contacts the bottom of the workpiece. When the motor drives the driving wheel to rotate, the driving wheel drives the workpiece to rotate.

[0017] Advantages of the present invention: By setting the positioning tooling, when the high-strength aluminum alloy welding equipment for the production of the resonant rod is used, it has an adjustable V-shaped positioning structure, and automatically completes the welding positioning operation of the resonant rod, avoiding the dislocation phenomenon of the resonant rod during welding, and improving its welding accuracy; During operation, by using the settings of the positioning tooling, it is equipped with an adjustable V-shaped limit fixing structure, enabling the center alignment between two groups of workpieces. When the user places the workpiece on the upper parts of the first bottom plate and the second bottom plate, the bottom of the workpiece contacts the two groups of side-rotating clamping plates on the first bottom plate and the second bottom plate. The side-rotating clamping plates are in a movable rotating state. By using the self-weight of the workpiece to press down the side-rotating clamping plates, one end of the two groups of side-rotating clamping plates tilts upward, and the two groups of side-rotating clamping plates are in a V-shaped structure and respectively clamp on both sides of the workpiece, making the workpiece located at the middle position of the first bottom plate and the second bottom plate. When the two groups of positioning tooling are respectively used for the installation operation of the workpiece, calibration is first carried out between the two groups of positioning tooling to make the two groups of positioning tooling align with each other. By using the two groups of positioning tooling to respectively position the two groups of workpieces, the two groups of workpieces are both in a centered state, so that the two groups of workpieces are centered and aligned during welding, avoiding the dislocation of their welds. The user can, according to the diameter size of the workpiece, use the sliding wheels to cooperate with the sliding grooves to move the first bottom plate and the second bottom plate, thereby adjusting the use distance of the side-rotating clamping plates on the first bottom plate and the second bottom plate, and playing a role in adjusting the size of the V-shaped structure of the side-rotating clamping plates. During the welding operation, the motor drives the lead screw, so that the lead screw drives the two groups of threaded sliding sleeves, and thus the two groups of positioning tooling move towards each other, making the workpieces on the two groups of positioning tooling dock with each other. The setting of the limit ejector rod plays a role in fixing the tail end of the workpiece after the workpiece is installed.

[0018] By setting the positioning roller rod and the auxiliary clamping seat, when using this high-strength aluminum alloy welding equipment for the production of resonant rods, it has a rotation assistance structure. In cooperation with the use of the positioning tooling, the centered rotation adjustment of resonant rods with different diameters can be completed, facilitating the rotation welding operation. During use, when the side-rotating clamping plate tilts and rotates under the action of the workpiece, the positioning roller rod is stuck on the side of the workpiece, and at the same time, the lower roller rod contacts the bottom of the workpiece, so that the workpiece remains in a movable rotating state, meeting the rotating use of the workpiece. Because the workpiece needs to be rotated and adjusted during welding, and the positioning roller rod can play an auxiliary positioning role when the workpiece rotates, preventing the workpiece from falling off the positioning tooling. Secondly, when workpieces with different diameters are installed, the positioning roller rod needs to be appropriately adjusted according to the rotation angle and position of the side-rotating clamping plate, so that the positioning roller rod can contact the sides of workpieces with different diameters. The use position of the positioning roller rod can be adjusted by using the auxiliary clamping seat, so as to meet the rotational limit of workpieces with different diameters. The user presses the pressure rod, so that the pressure rod can control the movement of the elastic top plate, making the elastic top plate loosen from the sliding groove. When the pressure rod is released, the elastic member pushes the elastic top plate, making the elastic top plate clamp tightly inside the sliding groove, completing the fixing operation of the auxiliary clamping seat.

[0019] By setting the welding part, when the high-strength aluminum alloy welding equipment for producing resonant rods is in use, in cooperation with the positioning tooling, multiple rotary welding operations on the resonant rods can be completed, improving the flexibility during welding. During operation, by setting the lifting table and the moving base, two-way position movement of the welding head can be achieved, enabling the welding head to complete welding operations of various shapes as shown in Figure 9 between two groups of workpieces. First, use the air cylinder to drive the lifting seat, so that the lifting seat drives the welding head to move up and down, thereby adjusting the use height of the welding head to make the welding head contact the weld seam. When performing the rotary welding operation on the workpiece, use the motor to drive the threaded rod to rotate, and use the threaded rod to drive the telescopic column to move outwards, so that the driving wheel at one end of the telescopic column contacts the bottom of the workpiece. When the motor drives the driving wheel to rotate, the driving wheel drives the workpiece to rotate. Secondly, use the horizontal push rod to drive the lifting table, so that the lifting table moves horizontally on the moving base, thereby horizontally adjusting the position of the welding head. Combined with the rotation of the workpiece, welding operations of various shapes of weld seams can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manner

[0023] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] As Figures 1 - 9 shown, a high-strength aluminum alloy welding device for the production of resonant rods includes a fixed base 1, a positioning tooling 2 and a welding part 4. The welding part 4 is arranged on the upper outer surface of the fixed base 1. The positioning tooling 2 is fixedly installed on the upper end of the fixed base 1 on one side of the welding part 4. The positioning tooling 2 includes a first bottom plate 6 and a second bottom plate 7. The first bottom plate 6 is fixedly installed on one side of the second bottom plate 7. Sliding clamp seats 9 are movably installed on the upper ends of both the first bottom plate 6 and the second bottom plate 7, and side-rotating clamping plates 10 are movably installed on the upper ends of the sliding clamp seats 9. The two groups of side-rotating clamping plates 10 are symmetrically arranged. A positioning roller rod 14 is movably installed on the upper end of the side-rotating clamping plate 10, and the side-rotating clamping plate 10 and the positioning roller rod 14 are movably connected through an auxiliary clamping seat 15.

[0025] To solve the calibration problem during the welding of resonant rods, as Figure 2As shown, a threaded sliding sleeve 8 is fixedly installed at the middle position of the lower end of the second base plate 7, and a limiting ejector rod 11 is fixedly installed at the middle position of the rear end of the first base plate 6. The overall shape of the limiting ejector rod 11 is an L-shaped structure. The first base plate 6 and the second base plate 7 are fixed by a rod body. When performing the welding and fixing operation of the resonant rod, by setting the positioning tooling 2, it has an adjustable V-shaped limiting and fixing structure, so that the two workpieces 17 are centered. When the user places the workpiece 17 on the upper parts of the first base plate 6 and the second base plate 7, the bottom of the workpiece 17 contacts the two side-rotating clamping plates 10 on the first base plate 6 and the second base plate 7. Due to the self-gravity of the workpiece 17, one end of the two side-rotating clamping plates 10 tilts upward. The two side-rotating clamping plates 10 are in a V-shaped structure and are respectively clamped on both sides of the workpiece 17. When the two positioning toolings 2 respectively perform the installation operation of the workpiece 17, the two workpieces 17 are both in a centered state, so that the two workpieces 17 are centered and aligned during welding, avoiding the dislocation of their welds.

[0026] As Figure 3 shown, the two threaded sliding sleeves 8 are driven by a lead screw. A sliding wheel 12 is arranged at the middle position of the lower end of the sliding clamp seat 9. Chutes for cooperating with the sliding wheel 12 are provided at the upper ends of the first base plate 6 and the second base plate 7. The user can move the first base plate 6 and the second base plate 7 according to the diameter size of the workpiece 17 by using the sliding wheel 12 in cooperation with the chute, so as to adjust the use distance of the side-rotating clamping plates 10 on the first base plate 6 and the second base plate 7, and play a role in adjusting the size of the V-shaped structure of the side-rotating clamping plates 10. During the welding operation, the lead screw is driven by a motor, so that the lead screw drives the two threaded sliding sleeves 8, and thus the two positioning toolings 2 move towards each other, enabling the workpieces 17 on the two positioning toolings 2 to be butted against each other. The setting of the limiting ejector rod 11 plays a role in fixing the tail end of the workpiece 17 after the workpiece 17 is installed.

[0027] A support block 13 is fixedly installed at the upper end of the sliding clamp seat 9. The side-rotating clamping plate 10 and the positioning roller rod 14 are movably connected through an auxiliary clamping seat 15. A positioning slider 29 is installed at the middle position of the lower end of the auxiliary clamping seat 15. A lower roller rod 32 is provided at one end of the side-rotating clamping plate 10. When the side-rotating clamping plate 10 tilts and rotates under the action of the workpiece 17, the positioning roller rod 14 is stuck on the side of the workpiece 17, and at the same time the lower roller rod 32 contacts the bottom of the workpiece 17, meeting the rotational use of the workpiece 17. Because the workpiece 17 needs to be rotated and adjusted during welding, the positioning roller rod 14 can play an auxiliary positioning role when the workpiece 17 rotates, avoiding the workpiece 17 falling off the positioning tooling 2. And the use position of the positioning roller rod 14 can be adjusted by using the auxiliary clamping seat 15, so as to meet the rotational limit of workpieces 17 with different diameters.

[0028] As Figure 7As shown in the figure, elastic top plates 30 are provided on both sides of the bottom of the auxiliary card seat 15 where the positioning slider 29 is located. The auxiliary card seat 15 and the elastic top plates 30 are elastically connected by elastic members 28. By using the elastic top plates 30 in cooperation with the elastic members 28, the auxiliary card seat 15 after movement can be fixed, facilitating the adjustment operation of the auxiliary card seat 15 at any position.

[0029] A pressure rod 31 is movably installed between the auxiliary card seat 15 and the elastic top plates 30. Roller shafts 16 are provided at the bottoms of the first bottom plate 6 and the second bottom plate 7. By pressing the pressure rod 31, the user can control the movement of the elastic top plates 30, causing the elastic top plates 30 to be released from the chute. When the pressure rod 31 is released, the elastic members 28 are used to push the elastic top plates 30, causing the elastic top plates 30 to be clamped inside the chute.

[0030] The welding part 4 includes a moving base 3 and a lifting platform 5. The lifting platform 5 is movably installed at the upper end of the moving base 3, and a welding head 23 is movably installed at the front end of the lifting platform 5. By using the settings of the lifting platform 5 and the moving base 3, the two-way position movement of the welding head 23 can be completed, enabling the welding head 23 to perform welding operations of various shapes between two groups of workpieces 17 as Figure 9 shown in the figure.

[0031] As Figure 5 shown in the figure, a lifting seat 22 is provided at the front end of the lifting platform 5. The welding head 23 is installed at the bottom of the lifting seat 22. The lifting platform 5 and the lifting seat 22 are driven by a cylinder 21. By using the cylinder 21 to drive the lifting seat 22, the lifting seat 22 drives the welding head 23 to move up and down, thereby adjusting the use height of the welding head 23.

[0032] As Figure 6 shown in the figure, a driving wheel 18 is movably installed in the middle of the moving base 3. A moving slider 20 is provided at the bottom of the lifting platform 5. The moving base 3 and the lifting platform 5 are driven by a horizontal push rod 19. By using the horizontal push rod 19, the lifting platform 5 can be driven, enabling the lifting platform 5 to move horizontally on the moving base 3.

[0033] One end of the driving wheel 18 is provided with a telescopic column 24, and a telescopic sleeve 27 is movably sleeved on the outer surface of the telescopic column 24. The telescopic column 24 and the telescopic sleeve 27 are driven by a threaded rod 26. A motor 25 is provided inside the telescopic sleeve 27. When performing the rotary welding operation of the workpiece 17, the motor 25 is used to drive the threaded rod 26 to rotate. By using the threaded rod 26 to drive the telescopic column 24 to move outwards, the driving wheel 18 at one end of the telescopic column 24 contacts the bottom of the workpiece 17. When the motor drives the driving wheel 18 to rotate, the driving wheel 18 drives the workpiece 17 to rotate.

[0034] Therefore, the welding of the resonance rod has certain requirements on precision. During the welding operation, the ends of the resonance rod need to maintain a coaxial alignment state. The misalignment state will affect the welding effect of the resonance rod. The above welding equipment does not have an auxiliary positioning structure. When it is used, it cannot automatically complete the centering alignment of the resonance rod, and it cannot be flexibly applied to resonance rods of different specifications. Secondly, the welding of the resonance rod is annular welding. During the welding operation, the resonance rod needs to be rotated and adjusted. The traditional welding equipment does not have a rotation auxiliary structure. When the rotation adjustment is performed, the resonance rod is prone to displacement, which affects its welding precision. At the same time, the traditional equipment cannot be flexibly applied to different types of welding structures, and can only be applied to conventional annular welding structures, which reduces its flexibility during welding operations. To this end, by setting the positioning tool 2, when the high-strength aluminum alloy welding equipment for the production of the resonance rod is used, it has an adjustable V-shaped positioning structure to automatically complete the welding positioning operation of the resonance rod, avoid the misalignment of the resonance rod during welding, and improve its welding accuracy; During operation, the positioning fixture 2 is set to have an adjustable V-shaped limit fixing structure so that the two groups of processing parts 17 are kept in center alignment. When the user places the processing part 17 on the upper part of the first bottom plate 6 and the second bottom plate 7, the bottom of the processing part 17 contacts the two groups of side rotating clamps 10 on the first bottom plate 6 and the second bottom plate 7. The side rotating clamps 10 themselves are in an active rotating state. The side rotating clamps 10 are pressed down by the weight of the processing part 17 itself, so that one end of the two groups of side rotating clamps 10 are tilted upward. The two groups of side rotating clamps 10 are respectively stuck on both sides of the processing part 17 in a V-shaped structure, so that the processing part 17 is located in the middle of the first bottom plate 6 and the second bottom plate 7. When the two groups of positioning fixtures 2 perform the installation operation of the processing part 17 respectively, the two groups of positioning fixtures 2 are calibrated so that the two groups of positioning fixtures 2 are mutually aligned. Alignment, using two sets of positioning fixtures 2 to respectively perform positioning operations on the two sets of workpieces 17, so that the two sets of workpieces 17 are in a centered state, so that the two sets of workpieces 17 are aligned in the center during welding, and the weld seams thereof are prevented from being misaligned. The user can use the sliding wheel 12 to cooperate with the sliding groove to move the first bottom plate 6 and the second bottom plate 7 according to the caliber of the workpiece 17, so as to adjust the use distance of the side rotating clamping plate 10 on the first bottom plate 6 and the second bottom plate 7, and play a role in adjusting the size of the V-shaped structure of the side rotating clamping plate 10. When performing the welding operation, the motor is used to drive the screw rod, so that the screw rod drives the two sets of threaded sleeves 8, so that the two sets of positioning fixtures 2 move toward each other, so that the workpieces 17 on the two sets of positioning fixtures 2 are butted against each other, and the setting of the limiting ejector rod 11 plays a role in fixing the tail end of the workpiece 17 after the workpiece 17 is installed; By setting the positioning roller 14 and the auxiliary holder 15, when the high-strength aluminum alloy welding equipment for the production of the resonance rod is used, it has a rotation auxiliary structure, and with the use of the positioning tool 2, the centering rotation adjustment of the resonance rods of different calibers can be completed, which is convenient for the rotation welding operation; During use, when the side-rotating clamping plate 10 tilts and rotates under the action of the workpiece 17, the positioning roller rod 14 is stuck on the side of the workpiece 17, and at the same time, the lower roller rod 32 is in contact with the bottom of the workpiece 17, so that the workpiece 17 is kept in a rotating state, meeting the rotating use of the workpiece 17. Since the workpiece 17 needs to be rotated and adjusted during welding, the positioning roller rod 14 can play an auxiliary positioning role when the workpiece 17 rotates, preventing the workpiece 17 from falling off the positioning tooling 2. Secondly, when workpieces 17 of different calibers are installed, the positioning roller rod 14 needs to be appropriately adjusted according to the rotation angle and position of the side-rotating clamping plate 10, so that the positioning roller rod 14 can be in contact with the sides of workpieces 17 of different calibers. The auxiliary clamping seat 15 can be used to adjust the use position of the positioning roller rod 14, thus meeting the rotational limit of workpieces 17 of different calibers. The user presses the pressure rod 31, so that the pressure rod 31 can control the movement of the elastic top plate 30, causing the elastic top plate 30 to loosen from the chute. When the pressure rod 31 is released, the elastic member 28 is used to push the elastic top plate 30, so that the elastic top plate 30 is clamped inside the chute, completing the fixing operation of the auxiliary clamping seat 15; By setting the welding part 4, when the high-strength aluminum alloy welding equipment for producing the resonant rod is in use, in cooperation with the use of the positioning tooling 2, multiple rotational welding operations of the resonant rod can be completed, improving its flexibility during welding; During operation, by setting the lifting table 5 and the moving base 3, two-way position movement of the welding head 23 can be completed, enabling the welding head 23 to complete welding operations of various shapes between two groups of workpieces 17 as shown in Figure 9 . First, the cylinder 21 is used to drive the lifting seat 22, so that the lifting seat 22 drives the welding head 23 to move up and down, thereby adjusting the use height of the welding head 23 and making the welding head 23 contact the weld seam. When performing the rotational welding operation of the workpiece 17, the motor 25 is used to drive the threaded rod 26 to rotate, and the threaded rod 26 is used to drive the telescopic column 24 to move outwards, so that the driving wheel 18 at one end of the telescopic column 24 is in contact with the bottom of the workpiece 17. When the motor drives the driving wheel 18 to rotate, the driving wheel 18 drives the workpiece 17 to rotate. Secondly, the horizontal push rod 19 can be used to drive the lifting table 5, so that the lifting table 5 moves horizontally on the moving base 3, thereby horizontally adjusting the position of the welding head 23. Combined with the rotation of the workpiece 17, welding operations of various-shaped weld seams can be realized.
