Therefore, when producing various models with relatively small demand, such as foreign trade models, it is necessary to frequently switch between different welding tooling, resulting in relatively low machine adjustment efficiency; moreover, for products with relatively small demand, the cost of using special tooling is relatively high. That is, the welding tooling for air-conditioning silencers in the prior art has a small scope of application, resulting in low production efficiency and high production costs. Utility Model Content

[0011] Furthermore, the support arm is provided with an adjustment slot along its length direction, and the fixed joint is fixedly arranged in the adjustment slot and can be adjusted in position along the extension direction of the adjustment slot.

[0012] Under this technical solution, due to the setting of the adjustment groove, the weight of the support arm is relatively light, and it can carry heavier muffler cylinders and pipes while the bearing capacity of the support frame remains unchanged; moreover, the position of the fixed joint is adjustable along the extension direction of the adjustment groove, that is, the adjustment of the position of the fixed joint can be achieved steplessly, thereby greatly expanding the scope of application of the welding tooling.

Therefore, such a setting can improve operational efficiency.

[0022] Furthermore, the fixing seat also includes a limit member, which is fixedly arranged on the support arm and can be adjusted along the length direction of the support arm; the limit member is provided with a limit groove, and the limit groove is used to set up the pipe of the air-conditioning silencer and prevent the pipe from moving in a direction perpendicular to its own center line.

[0024] Under this technical solution, when installing the support arm, the first opening can be enlarged and clamped to the support rod, and then the first extrusion piece can be installed to make the support rod and the first clamping ring tightly abut against each other, so as to fix the support arm to the support rod. When adjusting the position of the support arm, it is only necessary to remove the first extrusion piece, and after adjusting the position of the support arm, the first extrusion piece can be installed in place.

[0025] Furthermore, the first extrusion member is a first extrusion screw.

[0026] Under this technical solution, the first extrusion component can be fixed to the support arm by means of a threaded connection and is not easy to fall off the support arm.

[0027] Furthermore, the clamping mechanism includes a connecting arm and a telescopic arm, the connecting arm is vertically fixed to the support rod and its position is adjustable along the length direction of the support rod; the telescopic arm is telescopically arranged on the connecting arm along the direction away from and close to the support rod, and the telescopic arm adjusts the opening size by telescoping and clamps the cylinder of the air-conditioning muffler.

[0028] Under this technical solution, the connecting arm is used to adjust the position of the entire clamping mechanism on the support rod. The opening size and the distance from the support rod can be adjusted by stretching or compressing the telescopic arm, so as to quickly clamp the muffler barrel, which is very convenient and can greatly improve the machine adjustment efficiency.

[0029] Furthermore, a second clamping ring is provided at one end of the connecting arm connected to the support rod, the inner diameter of the second clamping ring is larger than the diameter of the support rod, the second clamping ring is provided with a second opening, and the second clamping ring is clamped on the outer peripheral wall of the support rod; the connecting arm is also provided with a second extrusion piece, the second extrusion piece is penetrated through the connecting arm perpendicular to the axial direction of the second clamping ring, and passes through the side of the second clamping ring opposite to the second opening and squeezes the support rod to abut against the second clamping ring.

[0030] Under this technical solution, when installing the connecting arm, its second opening can be enlarged and clamped on the support rod, and then the second extrusion piece can be installed to make the support rod and the second clamping ring tightly abut against each other, so as to fix the connecting arm to the support rod. When adjusting the position of the connecting arm, it is only necessary to remove the second extrusion piece, and after adjusting the position of the connecting arm, the second extrusion piece can be installed in place. Of course, the second clamping ring can also be directly sleeved from the top of the support rod to the outside of the support rod, and after adjusting the position of the clamping mechanism, the position can be fixed by the second extrusion piece.

[0031] Furthermore, the second extrusion member is a second extrusion screw.

[0032] Under this technical solution, the second extruded component can be fixed to the connecting arm by means of a threaded connection and is not easy to fall off the connecting arm.

[0033] Further, the telescopic arm comprises a pair of connecting rods and a pair of clamping claws, one end of each of the two connecting rods is rotatably connected to the connecting arm, and the other end is rotatably connected to one of the clamping claws, and the rotation axes at both ends of the connecting rods are parallel to the axis of the support rod;

After the silencer cylinder is clamped, if the relative position of the connecting rod and the connecting arm is fixed, the telescopic arm can maintain the state of clamping the silencer cylinder.

[0036] Furthermore, the telescopic arm also includes a connecting piece, both ends of which are movably connected to one of the clamping jaws respectively, and the connecting piece and the two clamping jaws connected thereto jointly surround an opening of the telescopic arm.

[0037] Under this technical solution, the connecting piece not only connects the two crossed jaws, but also can effectively prevent the muffler cylinder from moving toward the intersection of the two jaws after being clamped by the two jaws, especially when the diameter of the muffler cylinder is relatively small, thereby making the position of the muffler cylinder more stable.

[0038] Furthermore, the clamping mechanism includes two telescopic arms, which are spaced apart in a direction perpendicular to the telescopic direction, and each joint of the two telescopic arms is pivoted by a rotating shaft; the joints of the telescopic arms include the connection between the connecting rod and the connecting arm, the connection between the connecting rod and the clamping claw, and the connection between the connecting member and the clamping claw.

[0040] Furthermore, the rotating shaft is a threaded rod; the clamping mechanism also includes a handle, and the handle is screwed on the threaded rod connecting the connecting rod and the connecting arm.

[0041] Under this technical solution, after the telescopic arm clamps the muffler cylinder, the connecting rod can be pressed down by twisting the handle, so that the position of each connecting rod relative to the connecting arm is fixed, thereby keeping the telescopic arm clamped on the muffler cylinder.

[0042] Furthermore, a first protective tile is fixedly provided on one side of the clamping jaw facing the opening, the first protective tile is arc-shaped, curved inwards, and the axis thereof is perpendicular to the telescopic direction of the telescopic arm;

[0045] Furthermore, a sheath is provided outside the support rod, and the connecting arm is arranged outside the sheath.

[0046] Under this technical solution, the sheath can effectively reduce the wear of the connecting arm on the support rod and play a protective role for the support rod.

DETAILED DESCRIPTION

[0066] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0067] This embodiment provides a welding tool for an air conditioner muffler, such as Figures 1 to 3As shown, the welding tool includes a support frame 100 and a fixing seat 200 and a clamping mechanism 300 fixedly arranged on the support frame 100, the fixing seat 200 is used to fix the bottom of the cylinder of the air-conditioning muffler, the clamping mechanism 300 is used to clamp the cylinder, and at least one of the fixing seat 200 and the clamping mechanism 300 is adjustable in position along the arrangement direction of the two.

[0068] The air conditioner muffler welding tool provided in this embodiment includes a fixing seat 200 and a clamping mechanism 300. When in use, the bottom of the air conditioner muffler cylinder is fixed to the fixing seat 200, and the cylinder of the air conditioner muffler is clamped by the clamping mechanism 300, and the air conditioner muffler can be welded using a welding tool. Moreover, since at least one of the fixing seat 200 and the clamping mechanism 300 is adjustable in position along the arrangement direction of the two, the welding tool can be adapted to air conditioner muffler cylinders of different sizes by adjusting the distance between the fixing seat 200 and the clamping mechanism 300. That is, the air-conditioning muffler welding tool provided in the present embodiment can fix the air-conditioning muffler cylinder of different specifications and sizes for welding by adjusting the distance between the fixing seat 200 and the clamping mechanism 300, and has a wide range of applications and strong versatility; moreover, when using the welding tool provided in the present embodiment, there is no need to switch the welding tool when welding mufflers of different specifications and sizes, so the production efficiency can be improved; in addition, when using the welding tool provided in the present embodiment, the number of welding tools for welding mufflers of different specifications and sizes can be reduced, so the production cost can also be reduced.

[0069] Specifically, in this embodiment, the support frame 100 includes a support rod 120; along the length direction of the support rod 120, the fixing seat 200 and the clamping mechanism 300 are fixedly arranged on the support rod 120 at intervals and both are adjustable in position. In this arrangement, the support rod 120 occupies a small space, and the rod-shaped structure facilitates the arrangement and position adjustment of the fixing seat 200 and the clamping mechanism 300. The positions of the fixing seat 200 and the clamping mechanism 300 are both adjustable, so that the adjustment flexibility of the welding tool is higher.

[0070] Of course, in other embodiments of the present application, only one of the fixing seat 200 and the clamping mechanism 300 may be adjustable along the length direction of the support rod 120. For example, the fixing seat 200 is not adjustable along the length direction of the support rod 120, and only the clamping mechanism 300 is adjustable along the length direction of the support rod 120. The distance between the fixing seat 200 and the clamping mechanism 300 can also be adjusted.

[0071] Specifically, in this embodiment, Figures 1 to 3As shown, the fixing base 200 includes a support arm 210 and a fixing joint 230. The support arm 210 is fixed vertically to the support rod 120. The fixing joint 230 is used to fix the bottom of the cylinder. The fixing joint 230 is fixed to the support arm 210 and can be adjusted along the length direction of the support arm 210. In this way, the support arm 210 is a cantilever, which can avoid interference with the muffler cylinder and related pipes as much as possible; the distance between the fixing joint 230 and the support rod 120 is adjustable, so that it can be used for muffler cylinders with different cylinder diameters.

[0072] Specifically, in this embodiment, Figure 1 and Figure 2 As shown, the support arm 210 is provided with an adjustment slot 213 along its length direction, and the fixed joint 230 is fixedly penetrated in the adjustment slot 213 and can be adjusted in position along the extension direction of the adjustment slot 213. In this arrangement, due to the arrangement of the adjustment slot 213, the weight of the support arm 210 is relatively light, and when the bearing capacity of the support frame 100 remains unchanged, it can carry a heavier muffler cylinder and pipe; moreover, the fixed joint 230 is adjustable in position along the extension direction of the adjustment slot 213, that is, the adjustment of the position of the fixed joint 230 can be achieved steplessly, thereby greatly expanding the scope of application of the welding tool.

[0073] Of course, in other embodiments of the present application, multiple fixed positions can also be set along the length direction of the support arm 210. By fixing the fixed joint 230 at different fixed positions, the position of the fixed joint 230 can be adjusted to adapt to the silencer cylinder of the corresponding cylinder diameter.

[0074] Specifically, in this embodiment, Figures 1 to 3 As shown, the fixed joint 230 includes a body 231, a baffle 232 and a fastener 233. The baffle 232 is fixedly arranged on the outer peripheral wall of the body 231, and the fastener 233 is detachably arranged on the body 231; the body 231 is inserted into the adjustment slot 213, and the baffle 232 and the fastener 233 clamp the body 231 to the support arm 210. In this arrangement, during assembly, the body 231 provided with the baffle 232 can be first inserted into the adjustment slot 213 and adjusted to a good position, and then the fastener 233 can be installed on the body 231 and the body 231 can be fixed to the support arm 210.

[0075] Specifically, in this embodiment, the body 231 is provided with an external thread, the fastener 233 is a nut, and the internal thread of the nut matches the external thread on the body 231. When adjusting the position of the fixed joint 230, the body 231 can be moved by only loosening the nut without unscrewing the nut, so the adjustment efficiency can be improved.

[0076] It should be noted here that in other embodiments of the present application, the fastener 233 is not limited to a nut. For example, the main body 231 is provided with a fixing hole, and the fastener 233 is a fixing pin. By inserting the fixing pin into the fixing hole, the main body 231 can be fixed to the support arm 210.

[0077] Specifically, in this embodiment, the fixed joint 230 is provided with a nitrogen filling channel, which is used to fill nitrogen into the cylinder. In this way, the fixed joint 230 integrates the functions of fixing the cylinder and filling nitrogen, simplifying the structure of the welding tool.

[0078] Specifically, in this embodiment, the nitrogen filling channel and the fixed joint 230 are coaxially arranged.

[0079] Specifically, in this embodiment, Figure 3 As shown, one end of the fixing joint 230 connected to the cylinder is conical. In this arrangement, when the fixing joint 230 is inserted into the cylinder or the interface provided on the cylinder, the small head of the conical end can play a role in rapid positioning, and the side surface of the conical end can play a role in guiding, so this arrangement can improve the operation efficiency.

[0080] Specifically, in this embodiment, Figures 1 to 3 As shown, the fixing seat 200 also includes a limit member 240, which is fixedly arranged on the support arm 210 and can be adjusted along the length direction of the support arm 210; the limit member 240 is provided with a limit groove 241, which is used to set up the pipe of the air conditioner silencer and prevent the pipe from moving in a direction perpendicular to its own center line.

[0081] Specifically, in this embodiment, the fixing method of the limiter 240 is consistent with the fixing method of the fixed joint 230, and the position adjustment of the limiter 240 can also be steplessly adjusted, so the limiter 240 can adapt to different pipelines.

[0082] More specifically, in this embodiment, if Figure 1 and Figure 2 As shown, the body of the limiting member 240 is roughly in a "Y" shape.

[0083] Specifically, in this embodiment, Figure 2As shown, a first clamping ring 211 is provided at one end of the support arm 210 connected to the support rod 120. The inner diameter of the first clamping ring 211 is larger than the diameter of the support rod 120. The first clamping ring 211 is provided with a first opening 212. The first clamping ring 211 is clamped on the outer peripheral wall of the support rod 120. The support arm 210 is also provided with a first extrusion piece 220. The first extrusion piece 220 is perpendicular to the axial direction of the first clamping ring 211 and penetrates the support arm 210. The first extrusion piece 220 passes through the side of the first clamping ring 211 opposite to the first opening 212 and squeezes the support rod 120 to abut against the first clamping ring 211. In this arrangement, when installing the support arm 210, the first opening 212 can be enlarged and clamped on the support rod 120, and then the first extrusion piece 220 is installed to make the support rod 120 and the first clamping ring 211 closely abut, thereby fixing the support arm 210 to the support rod 120. When adjusting the position of the support arm 210 , it is only necessary to remove the first extrusion member 220 , and then install the first extrusion member 220 in place after the position of the support arm 210 is adjusted.

[0084] Specifically, in this embodiment, the first extrusion member 220 is a first extrusion screw. With such a configuration, the first extrusion member 220 can be fixed to the support arm 210 by threaded connection, and is not easy to fall off from the support arm 210. Of course, in other embodiments of the present application, the first extrusion member 220 is not limited to the structural form of a screw. For example, the first extrusion member 220 can also be a first extrusion pin. As long as it can squeeze the support rod 120, so that the mutual position of the support rod 120 and the first clamping ring 211 is fixed, the present application may not limit the specific structure of the first extrusion member 220.

[0085] Specifically, in this embodiment, Figure 1 and Figure 2 As shown, the clamping mechanism 300 includes a connecting arm 310 and a telescopic arm 330. The connecting arm 310 is vertically fixed to the support rod 120 and can be adjusted in position along the length direction of the support rod 120. The telescopic arm 330 is telescopically arranged on the connecting arm 310 in the direction away from and close to the support rod 120. The telescopic arm 330 adjusts the opening size and clamps the cylinder of the air conditioner muffler by telescoping. In this setting form, the connecting arm 310 is used to adjust the position of the entire clamping mechanism 300 on the support rod 120. By stretching or compressing the telescopic arm 330, the opening size and the distance from the support rod 120 can be adjusted, thereby quickly clamping the cylinder of the muffler, which is very convenient and can greatly improve the adjustment efficiency.

[0086] Specifically, in this embodiment, Figure 2 and Figure 5As shown, a second clamping ring 311 is provided at one end of the connecting arm 310 connected to the support rod 120, the inner diameter of the second clamping ring 311 is larger than the diameter of the support rod 120, the second clamping ring 311 is provided with a second opening 312, and the second clamping ring 311 is clamped on the outer peripheral wall of the support rod 120; the connecting arm 310 is also provided with a second extrusion piece 320, the second extrusion piece 320 is perpendicular to the axial direction of the second clamping ring 311 and penetrates the connecting arm 310, and passes through the side of the second clamping ring 311 opposite to the second opening 312 and squeezes the support rod 120 to abut against the second clamping ring 311. In this arrangement, when installing the connecting arm 310, the second opening 312 can be enlarged and clamped on the support rod 120, and then the second extrusion piece 320 is installed to make the support rod 120 and the second clamping ring 311 closely abut, thereby fixing the connecting arm 310 to the support rod 120. When adjusting the position of the connecting arm 310, it is only necessary to remove the second extrusion member 320, and after adjusting the position of the connecting arm 310, install the second extrusion member 320 in place. Of course, the second clamping ring 311 can also be directly sleeved on the outside of the supporting rod 120 from the top end of the supporting rod 120, and after adjusting the position of the clamping mechanism 300, the second extrusion member 320 can be used to fix the position.

[0087] Specifically, in this embodiment, the second extrusion member 320 is a second extrusion screw. With such a configuration, the second extrusion member 320 can be fixed to the connecting arm 310 by threaded connection, and is not easy to fall off from the connecting arm 310. Of course, in other embodiments of the present application, the second extrusion member 320 is not limited to the structural form of a screw. For example, the second extrusion member 320 can also be a second extrusion pin. As long as it can squeeze the support rod 120, so that the relative position of the support rod 120 and the second clamping ring 311 is fixed, the present application may not limit the specific structure of the second extrusion member 320.

[0088] Specifically, in this embodiment, Figures 4 to 11 As shown, the telescopic arm 330 includes a pair of connecting rods 331 and a pair of clamping claws 332. The two connecting rods 331 are rotatably connected to the connecting arm 310 at one end, and the other end is rotatably connected to a clamping claw 332, and the rotation axes of the two ends of the connecting rod 331 are parallel to the axis of the support rod 120; the clamping claw 332 is in a "J" shape, and the two clamping claws 332 are crossed and rotatably connected to each other. The axis of rotation of the two clamping claws 332 is parallel to the axis of the support rod 120, and the two clamping claws 332 are arranged at one end away from the connecting rod 331 to form an opening for clamping the cylinder. Such a setting realizes that the opening of the telescopic arm 330 increases when it is compressed and decreases when it is stretched. Therefore, when in use, the muffler cylinder can be quickly clamped by first retracting and then stretching. After the muffler cylinder is clamped, if the relative position of the connecting rod 331 and the connecting arm 310 is fixed, the telescopic arm 330 can maintain the state of clamping the muffler cylinder.

[0089] Specifically, in this embodiment, Figures 4 to 6 As shown, the telescopic arm 330 also includes a connecting member 333, and both ends of the connecting member 333 are movably connected to a clamping claw 332 respectively. The connecting member 333 and the two clamping claws 332 connected thereto together surround the opening of the telescopic arm 330. In this arrangement, the connecting member 333 not only connects the two crossed clamping claws 332, but also can effectively prevent the muffler cylinder from moving toward the intersection of the two clamping claws 332 after being clamped by the two clamping claws 332, especially when the cylinder diameter of the muffler cylinder is relatively small, so that the position of the muffler cylinder can be more stable.

[0090] Specifically, in this embodiment, Figure 8 and Fig. 9 As shown, the connecting member 333 is a connecting plate with a corner, and the corner is an obtuse angle, for example: the size of the angle γ is 110°, of course, it is not limited to this value; the two ends of the connecting plate are respectively connected to one of the two clamping jaws 332.

[0091] Specifically, in this embodiment, Figures 1 to 3 as well as Figure 6 and Figure 7 As shown, the clamping mechanism 300 includes two telescopic arms 330, which are arranged at intervals in a direction perpendicular to the telescopic direction, and each joint of the two telescopic arms 330 is pivoted by a rotating shaft 340; the joints of the telescopic arms 330 include the connection between the connecting rod 331 and the connecting arm 310, the connection between the connecting rod 331 and the clamping claw 332, and the connection between the connecting member 333 and the clamping claw 332. In this way, the clamping mechanism 300 has a relatively long clamping length for the muffler cylinder along the axial direction of the muffler cylinder, so the clamping and fixing effect of the muffler cylinder is better.

[0092] Specifically, in this embodiment, Figure 6 As shown, the rotating shaft 340 is a threaded rod; the clamping mechanism 300 also includes a handle 360, which is screwed on the threaded rod connecting the connecting rod 331 and the connecting arm 310. In this way, after the telescopic arm 330 clamps the muffler cylinder, the connecting rod 331 can be pressed down by screwing the handle 360, so that the position of each connecting rod 331 relative to the connecting arm 310 is fixed, and the telescopic arm 330 keeps the muffler cylinder clamped.

[0093] Specifically, in this embodiment, Figure 6 and Figure 8As shown, a first protective tile 351 is fixedly arranged on the side of the clamping jaw 332 facing the opening. The first protective tile 351 is arc-shaped, inwardly curved, and its axis is perpendicular to the telescopic direction of the telescopic arm 330. A second protective tile 352 is fixedly arranged on the side of the connecting member 333 facing the opening. The second protective tile 352 is arc-shaped, inwardly curved, and its curvature is consistent with that of the first protective tile 351, and its axis is perpendicular to the telescopic direction of the telescopic arm 330. In this way, the protective tile increases the contact area between the telescopic arm 330 and the muffler cylinder, so the clamping effect on the muffler cylinder can be improved.

[0094] It should be noted here that in other embodiments of the present application, only the first protective tile 351 or only the second protective tile 352 may be provided.

[0095] More specifically, in this embodiment, if Figure 8 As shown, the central angle corresponding to the second protective tile 352 is greater than the central angle corresponding to the first protective tile 351 , for example: the central angle β corresponding to the second protective tile 352 is 60°, and the central angle α corresponding to the first protective tile 351 is 30°.

[0096] Specifically, in this embodiment, Figures 1 to 3 As shown, the support rod 120 is also covered with a sheath 121, and the connecting arm 310 is arranged outside the sheath 121. In this arrangement, the sheath 121 can effectively reduce the wear of the connecting arm 310 on the support rod 120, and play a protective role on the support rod 120.

[0097] Specifically, in this embodiment, the support rod 120 is provided with scale marks along its length direction. In this way, the adjustment distance of the fixing seat 200 and the clamping mechanism 300 is visualized, and the fixing seat 200 and the clamping mechanism 300 can be quickly adjusted according to the height size of the muffler cylinder, thereby improving the adjustment efficiency. As for the scale spacing, it can be set according to the adjustment accuracy, for example: the scale spacing can be 1 cm.

[0098] Specifically, in this embodiment, Figures 1 to 3 As shown, the support frame 100 also includes a base plate 110, and a support rod 120 is vertically fixed to the base plate 110. The base plate 110 can be fixedly installed on a turntable, and the turntable is used to drive the welding tool and the air conditioner muffler thereon to rotate, so that the welding tool can weld the air conditioner muffler.
