Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, and particularly relates to a welding device for a fixed circulator. Background Art

[0002] A circulator includes materials such as a cavity, PIN pins, magnets, magnetic shims, ferrites, central conductors, cover plates, etc. Among them, the cover plate and the cavity mostly adopt a spiral fastening method. With the continuous upgrading of communication systems, products have gradually become smaller, evolving into a riveting process for stamping cavities and cover plates, effectively improving the limitation of thread fastening on their thickness dimensions.

[0003] Currently, circulator products are formed by stacking multiple materials and then cooperating the cover plate with the cavity. To achieve product performance, the tightness of the material cooperation has a great impact on product performance. Currently, the stamping cavity and the cover plate adopt a riveting process. Due to factors such as time, climate, vibration, and the stress release of the metal itself after deformation, the product materials will not be fastened firmly, resulting in a decline in product performance. Moreover, this hidden danger is random, increasing the difficulty of early prevention. Therefore, it is necessary to use welding to connect the cavity and the cover plate. Summary of the Utility Model

[0004] To solve the technical problems in the background art, the utility model proposes a welding device for a fixed circulator.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0006] A welding device for a fixed circulator includes a welding base, on which a bearing table is slidably arranged. A fixed carrier plate is arranged on the bearing table, and a plurality of fixing grooves for positioning the fixed circulator are arranged on the fixed carrier plate. And a welding head is movably arranged on the welding base;

[0007] The fixed circulator includes a cavity and a cover plate arranged in the cavity. Fixed support feet are formed on the cavity. The welding head presses the fixed support feet to bend the fixed support feet and press the cover plate tightly. And the welding head abuts against the fixed support feet and releases high-frequency current to weld the cover plate on the cavity.

[0008] Preferably, the welding seat is provided with a fixing structure for pressing the fixed annular device, the fixing structure includes a plurality of claws rotated on the fixed carrier plate, and a driving unit driving the claws to rotate, the action end of the driving unit rises and drives the claws away from the fixed annular device, and the action end of the driving unit descends and drives the claws to press the fixed annular device. Through the above improvements, the fixed annular device is placed in the fixing groove of the fixed carrier plate, and then the driving unit descends and pulls the claws to rotate, so that the claws press the fixed annular device, thereby ensuring the stability of the fixed annular device during the welding process. In addition, the claws fix the product while preventing the cavity from expanding, so that the outer diameter of the product is guaranteed.

[0009] Preferably, the clamping claws are arranged at intervals on the outer periphery of the fixed annulator, and the clamping claws have a clamping portion for clamping the fixed annulator, a hinged portion hinged on the fixed carrier plate, and a connecting portion connected to the driving unit, and a connecting block is provided on the output end of the driving unit, and a sliding groove is provided on the connecting block, and the connecting portion is slidably arranged in the sliding groove. Through the above improvements, when the fixed annulator needs to be fixed, the driving unit drives the connecting portion to descend, so that the connecting portion slides in the sliding groove, so that the clamping portion clamps the top of the fixed annulator from the outer periphery of the fixed annulator, thereby greatly improving the stability of the fixed annulator during welding, and the sliding groove can limit the rotation stroke of the clamping claw to prevent the clamping claw from crushing the fixed annulator.

[0010] Preferably, a connecting component is provided in the cavity, and the connecting component has a connecting leg extending out of the cavity, and the fixing groove includes a positioning groove for the cavity to be placed, and a first limiting groove for the connecting leg to be placed.

[0011] Preferably, the fixing groove further includes a second limiting groove extending in the direction of the first limiting groove, and the radial dimension of the second limiting groove is larger than that of the first limiting groove, and the depth of the second limiting groove is smaller than that of the first limiting groove. Through the above improvements, the entire fixing groove can be adapted to circulators of different sizes. When a larger circulator needs to be welded, the connecting leg can be placed in the second limiting groove for positioning, so that the entire fixed carrier can be compatible with circulators of multiple models.

[0012] Preferably, the welding head is formed with an abutment cavity for placing the fixed annular device, and a bending guide surface is formed in the abutment cavity. When the welding head abuts the fixed annular device, the fixed legs bend along the bending guide surface and press the cover plate. With the above improvements, when welding is performed, as the welding head continues to descend, the fixed legs will bend along the bending guide surface and press the cover plate.

[0013] Preferably, the number of the fixed feet is three, and the fixed feet are arranged at equal intervals along the circumferential direction of the cover plate. Through the above improvement, the fixed feet are arranged at equal intervals along the outer periphery of the cover plate and press the cover plate, ensuring the stability of the fixation of the cover plate.

[0014] Preferably, the connection assembly and the cover plate are placed in the cavity, the cover plate is arranged on the connection assembly, and the fixed feet are bent and press the cover plate, so that one end of the cover plate abuts against the connection assembly and the other end abuts against the fixed feet.

Detailed implementation mode

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. 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 shall fall within the protection scope of the present invention.

[0027] It should be understood that although the terms upper, middle, lower, top, one end, etc. appear in this article to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for easy understanding, rather than to define any directional or sequential limitations.

[0028] As Figures 1-6 shown, a welding device for a fixed circulator includes a welding base 1, a fixed carrier plate 2 is arranged on the welding base 1, a fixing groove 3 for positioning the fixed circulator 5 is arranged on the fixed carrier plate 2, and a welding head 4 is movably arranged on the welding base 1.

[0029] Specifically, the fixed circulator 5 includes a cavity 101 and a cover plate 102 arranged in the cavity 101. A fixed support leg 109 is formed on the cavity 101. The welding head 4 presses the fixed support leg 109 to bend the fixed support leg 109 and press the cover plate 102, and the welding head 4 abuts against the fixed support leg 109 and releases high-frequency current to weld the cover plate 102 to the cavity 101.

[0030] By placing the fixed circulator 5 in the fixing groove 3 on the fixed carrier plate 2 and pressing the fixed circulator 5 on the fixed carrier plate 2 by the descending of the welding head 4, the fixed support leg 109 on the fixed circulator 5 is bent and pressed against the cover plate 102. And the welding head 4 can concentrate the high-frequency electrical energy on the surface layer of the product to be welded through the skin effect of the high-frequency current, and weld the cavity 101 and the cover plate 102. Compared with the riveting process, the connection between the cavity 101 and the cover plate 102 is more reliable and has higher reliability.

[0031] In addition, during the welding process, a PLC is used to control the time nodes. First, the welding head 4 presses down to complete the bending of the fixing feet 109, compacting the internal materials. Then, high-frequency welding is carried out by energizing to weld the cover plate 102 to the cavity 101. Secondly, after a 1-second pause, the welding head 4 lifts up and the welding is completed.

[0032] Since the current is highly concentrated on the surfaces of the cover plate 102 and the cavity 101 of the product to be welded during welding, the heating speed is extremely fast, and the self-cooling effect of the product to be welded is strong. Therefore, not only is the heat-affected zone small, but it has no influence on other materials and product performance, and the welding points are reliable.

[0033] Preferably, the number of the fixing feet 109 is 3, and the fixing feet 109 are arranged at equal intervals along the circumferential direction of the cover plate 102 and press against the cover plate 102, ensuring the stability of the fixation of the cover plate 102.

[0034] As Figures 1-6 shown, for a further explanation of the implementation manner of the fixed circulator 5 in this embodiment, a connection component 103 is arranged in the cavity 101, and the connection component 103 has a connection foot 104 extending out of the cavity 101. The fixed groove 3 includes a positioning groove 105 for placing the cavity 101 and a first limiting groove 106 for placing the connection foot 104.

[0035] During the feeding process of the fixed circulator 5, the cavity 101 is aligned by using the positioning groove 105 first, and the first limiting groove 106 can limit the connection foot 104, thus ensuring the stability of the placement of the entire circulator and improving the welding effect.

[0036] As a preference, the connection component 103 and the cover plate 102 are placed in the cavity 101. The cover plate 102 is arranged on the connection component 103, and the fixing feet 109 are bent and press against the cover plate 102, so that one end of the cover plate 102 abuts against the connection component 103 and the other end abuts against the fixing feet 109, making the connection component 103 and the cover plate 102 inside the cavity 101 fit tightly, improving the structural stability of the entire fixed circulator 5.

[0037] As Figures 1-6 shown, for a further improvement of the cooperation between the welding head 4 and the fixed circulator 5 in this embodiment, a butt joint cavity 110 for placing the fixed circulator 5 is formed on the welding head 4, and a bending guide surface 108 is formed in the butt joint cavity 110. When the welding head 4 abuts against the fixed circulator 5, the fixing feet 109 are bent along the bending guide surface 108 and press against the cover plate 102.

[0038] When welding, as the welding head 4 continuously descends, the welding head 4 will squeeze the fixed support leg 109. The fixed support leg 109 will be bent along the bending guide surface 108 and press against the cover plate 102. Subsequently, the welding head 4 will discharge electricity to weld the fixed support leg 109 and the cover plate 102 together.

[0039] As Figures 1-6 shown, as a further explanation of the fixing method of the fixed carrier plate 2 in this embodiment, a fixing structure 6 for pressing the fixed circulator 5 is provided on the welding seat 1. The fixing structure 6 includes a plurality of clamping claws 201 rotatably arranged on the fixed carrier plate 2, and a driving unit 202 for driving the clamping claws 201 to rotate. The action end of the driving unit 202 rises and drives the clamping claws 201 away from the fixed circulator 5. The action end of the driving unit 202 descends and drives the clamping claws 201 to press against the fixed circulator 5.

[0040] When welding, first place the fixed circulator 5 in the fixing groove 3 of the fixed carrier plate 2. Subsequently, the driving unit 202 descends and pulls the clamping claws 201 to rotate, so that the clamping claws 201 press against the fixed circulator 5. After welding, the action end of the driving unit 202 descends to make the clamping claws 201 disengage from the fixed circulator 5, thus ensuring the stability of the fixed circulator during the welding process.

[0041] Specifically, the clamping claws 201 are arranged at intervals on the outer periphery of the fixed circulator 5, and the clamping claws 201 have a pressing portion 203 for pressing the fixed circulator 5, a hinged portion 204 hinged on the fixed carrier plate 2, and a connecting portion 205 connected to the driving unit 202. A connecting block 206 is provided on the output end of the driving unit 202, and a sliding groove 207 is provided on the connecting block 206. The connecting portion 205 is slidably arranged in the sliding groove 207.

[0042] When it is necessary to fix the fixed circulator 5, the driving unit 202 drives the connecting portion 205 to descend, so that the connecting portion 205 slides in the sliding groove 207, and the pressing portion 203 presses the top of the fixed circulator 5 from the outer periphery of the fixed circulator 5, thereby greatly improving the stability of the fixed circulator 5 during the welding process. And the sliding groove 207 can limit the rotation stroke of the clamping claws 201 to avoid the clamping claws 201 damaging the fixed circulator 5.

[0043] In addition, while the clamping claws 201 fix the product, the cavity 101 is prevented from expanding, ensuring the outer diameter of the product.

[0044] As Figure 1 shown, specifically, for a further explanation of the implementation manner of the welding head 4, a lifting module 210 is provided on the welding seat 1, and the welding head 4 is connected to the action end of the lifting module 210.

[0045] When welding, the moving end of the lifting module 210 can move up and down, driving the welding head 4 to lift, so as to realize the bending and welding of the fixed circulator.

[0046] Furthermore, a connection input block connected to the power supply is provided on the welding head 4, and a connection hole 209 for the electrode input block 208 to extend is formed on the welding seat 1, improving the convenience of external electrode input connection.

[0047] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
