[0030] The specific embodiments of the present application have been shown through the above drawings, and will be described in more detail hereinafter. These drawings and written descriptions are not intended to limit the scope of the concept of the present application by any means, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION
[0031] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model below. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model. In the case of no conflict, the following embodiments and the features in the embodiments can be combined with each other.
[0032] As described in the background, generally, pipe fittings with different welding requirements and materials are welded by using the melting electrode active gas protection welding and the tungsten inert gas welding.
[0033] The melting electrode active gas protection welding (MAG welding) has a built-in wire feeding mechanism in the MAG welding machine to deliver the welding wire. The melting electrode, that is, the welding wire itself, is melted through the electrode, and active gas (such as carbon dioxide added in argon) is used to protect the arc and the molten pool. The welding penetration is strong, the welding current density is large, and the cost is low, so it is more suitable for welding large batches of carbon steel pipe fittings, low alloy steel pipe fittings or stainless steel pipe fittings. In the prior art, when the pipe fittings are MAG welded, the pipe fittings can be clamped by the positioner, the pipe fittings are driven to rotate around the axial direction of the pipe fittings by the positioner, and the operator manually holds the welding gun of the welding machine to weld the pipe fittings circumferentially as the positioner rotates. Or, in the case of not having a positioner, the operator can hold the pipe fittings with one hand and hold the welding gun of the welding machine with the other hand to manually weld and adjust the position of the pipe fittings.
[0034] The tungsten inert gas welding (TIG welding machine) can choose whether to use a welding wire according to the welding requirements. In general, a welding wire is selected to be used. It protects the arc and the molten pool by inert gas (usually argon). Since no flux is used, there is no spatter during the welding process, and the weld formation is relatively delicate, so it is more suitable for welding thin-walled stainless steel, aluminum, magnesium, titanium and other non-ferrous metal pipe fittings or black metal pipe fittings. In the prior art, when the pipe fittings are TIG welded, the pipe fittings can be clamped by the positioner and driven to rotate around the axial direction of the pipe fittings. The operator delivers the welding wire with one hand and holds the welding gun of the welding machine with the other hand to weld the pipe fittings circumferentially as the pipe fittings rotate. In the case of not having a positioner, the operator can only manually adjust the position of the pipe fittings and weld repeatedly.
[0035] However, during manual welding, the operation skill, experience accumulation, physical strength and energy of the operator are limited, so that defects such as incomplete penetration of the pipe and uneven weld formation are prone to occur during pipe welding. In addition, during manual welding without using a positioner, the orientation of the pipe needs to be adjusted and the welding gun needs to be picked up and put down as the weld continues, which will cause the pipe welding to be interrupted multiple times and the welding efficiency to be low.
[0036] In order to overcome the defects in the prior art, the pipe welding equipment provided by the embodiments of the present application is provided. The positioner is arranged on the rack, the welding machine and the welding gun support are arranged, the positioner clamps the pipe to be welded and drives the pipe to rotate, and the welding gun support clamps the welding gun of the welding machine. In this way, when the pipe is rotated by the positioner, the welding gun support can clamp the welding gun to stably weld the pipe at the same time. The pipe rotation and pipe welding are performed at the same time. Compared with manual welding with a welding gun, the pipe welding equipment provided by the embodiments of the present application can form a more uniform and beautiful weld, has higher welding efficiency, and has higher pipe welding quality.
[0037] The content of the present application will be described in detail below with reference to the drawings, so that those skilled in the art can more clearly and specifically understand the content of the present application.
[0038] Referring to Figure 1 and Figure 2 The pipe welding equipment provided by the embodiments of the present application includes a rack 100, a positioner 200, a welding machine 300 and a welding gun support 400. The positioner 200 is arranged on the rack 100, and the positioner 200 is used to clamp a pipe 700 to be welded and drive the pipe 700 to rotate around the center axis of the pipe 700. The welding machine 300 is connected with a welding gun 310. The welding gun support 400 includes a support 410, an adjusting assembly 420 and a clamping piece 430. The support 410 is connected with the rack 100. The adjusting assembly 420 is arranged on the support 410. The clamping piece 430 is arranged on the adjusting assembly 420 and clamps the welding gun 310. The clamping piece 430 drives the welding gun 310 to be located at the welding position of the pipe 700 through the support 410 and the adjusting assembly 420.
[0039] The rack 100 is arranged in a machining workshop or other production and machining site for pipe welding, and is in stable contact with a placement surface such as the ground of the machining site, so as to provide stable support for the equipment and workpieces on the rack 100, so as to ensure that the pipe 700 is stably and smoothly welded.
[0040] First of all, it should be noted that Figures 1 to 4X, Y, Z respectively correspond to the first direction, the second direction and the third direction, and X, Y, Z are perpendicular to each other in a three-dimensional space.
[0041] It should be noted that the positioner 200 is an auxiliary equipment widely used in the welding field, mainly used to change the operating position of the welding part, welding machine 300 or welder during the welding process to reach and maintain at the appropriate welding position. The positioner 200 has rotation and overturning functions, and can be divided into rotary positioner 200, tilting positioner 200 and lifting positioner 200 according to application requirements and process requirements. For the pipe 700 welding requirements of the present application, the rotary positioner 200 can be selected. Exemplarily, the positioner 200 is fixedly placed on the gantry 100, clamping the end of the pipe 700 to drive the pipe 700 to rotate around the center axis of the clamped part of the pipe 700 during operation. It can be understood that the pipe 700 welding is mainly to weld two pipe 700, when the positioner 200 clamps one pipe 700, if the positioner 200 is equipped with a center, and the structure cooperates with the positioner 200 clamping structure, the other pipe 700 can be tightly clamped on the pipe 700 clamped by the positioner 200 through the center, if the positioner 200 is not equipped with a center and the like structure, the two pipe 700 to be welded are pre-welded at the weld before the pipe 700 clamped by the positioner 200 is welded, so that the two pipe 700 are stably connected.
[0042] The welding machine 300 can clamp the electrode through the welding gun 310, so that the electrode contacts the pipe 700 to be welded, generates high temperature through the electric arc, so that the electrode melts and fills the welding part of the pipe 700, and the welding is completed. Or the electrode is provided on the welding gun 310, and the electrode generates high temperature to directly melt the welding part of the pipe 700.
[0043] The welding gun support 400 is provided on the gantry 100, which includes a support 410, an adjusting assembly 420 and a clamping piece 430. The support 410 provides mounting support for the welding assembly and the clamping piece 430. The adjusting assembly 420 is arranged on the support 410 and connected with the clamping piece 430 to cooperate with the support 410 to jointly adjust the position and posture of the clamping piece 430. The clamping piece 430 can clamp the welding gun 310. In this way, the welding gun support 400 can drive the welding gun 310 to move to the welding part of the pipe 700 to be welded, and the welding gun support 400 can stably hold the welding gun 310 at the welding part. Compared with manually holding the welding gun 310 at the welding part, the stability of the welding gun support 400 is higher.
[0044] Therefore, the pipe welding device provided by the embodiment of the present application can rotate the pipe to be welded 700 through the positioner 200, clamp the welding torch 310 of the welding machine 300 through the clamping member 430, and adjust the position of the clamping member 430 and the welding torch 310 through the support member 410 and the adjusting assembly 420, so that the pipe to be welded 700 can be stably welded through the welding torch 310 clamped by the welding torch support 400 when the pipe to be welded 700 is rotated by the positioner 200. In this way, the pipe to be welded 700 can be rotated and welded at the same time, and the welding seam formed by the pipe welding device provided by the embodiment of the present application is more uniform and beautiful, the welding efficiency is higher, and the welding quality of the pipe to be welded 700 is higher.
[0045] In some embodiments, referring to Figure 1 and Figure 2 , the gantry 100 comprises: a table top 110, the positioner 200 and the welding torch support 400 are arranged on the table top 110; a supporting leg 120, the supporting leg 120 supports the table top 110 to form an accommodation space on the side of the table top 110 facing the supporting leg 120, and the welding machine 300 is arranged in the accommodation space.
[0046] It can be understood that the table top 110 is stably supported on the placement surface of the pipe welding device by the supporting leg 120. The table top 110 is parallel or horizontal to the placement surface to ensure the stability of the positioner 200, the welding torch support 400 and other devices arranged thereon. The supporting leg 120 forms a gap between the table top 110 and the placement surface, and the gap forms an accommodation space. In this way, the welding machine 300 and other devices can be arranged in the accommodation space, so that the welding machine 300 and other devices are closer to the pipe to be welded 700, and the space occupation of the pipe welding device as a whole is reduced, and the space utilization is improved.
[0047] In some embodiments, referring to Figure 1 and Figure 2 , the support member 410 is slidably connected with the gantry 100 in at least one of a first direction and a second direction, and the adjusting assembly 420 is slidably connected with the support member 410 in a third direction; the first direction, the second direction and the third direction are perpendicular to each other.
[0048] It can be understood that the support member 410 is arranged on the table top 110 and extends in the third direction, i.e. Figure 1 and Figure 2The support 410 extends in the Z direction to be perpendicular to the table 110. The support 410 is slidingly connected to the table 110 in at least one of the first direction and the second direction, so that the overall movement of the welding gun support 400 can be realized by the sliding of the support 410 along the table 110, and the pipe welding device is suitable for welding pipe 700 of different sizes.
[0049] For example, the table 110 is provided with a sliding groove 112, and the bolt passes through the sliding groove 112 and is connected to the bottom of the support 410, so that when the bolt is loosened, the support 410 can drive the bolt to slide along the extension direction of the sliding groove 112 under the guidance of the sliding groove 112, and when the bolt is tightened, the support 410 can be fastened at the current position.
[0050] In this embodiment, the sliding groove 112 extends in the first direction, that is, Figure 1 and Figure 2 the X direction to adapt to pipe 700 of different lengths, and in other embodiments, the sliding groove 112 can also extend in the second direction (for example, Figure 1 and Figure 2 the Y direction) to adapt to pipe 700 of different diameters, or two groups of sliding grooves 112 are provided to extend in the first direction and the second direction respectively, and the present application does not limit this.
[0051] The adjustment assembly 420 is arranged on the support 410, and the support 410 is provided with a sliding groove 112 extending in the third direction (for example, Figure 1 and Figure 2 the Z direction), so that the adjustment assembly 420 is slidingly connected to the support 410 in the third direction. The adjustment assembly 420 slides in the third direction, and cooperates with the support 410 to slide in the first direction, so that the welding gun support 400 can more flexibly adapt to pipe 700 of different sizes to be welded.
[0052] For example, the bolt can also pass through the sliding groove 112 on the support 410 and be connected to the adjustment assembly 420, and the tightening or loosening of the bolt can realize the fastening and sliding of the adjustment assembly 420 along the support 410. In other embodiments, the sliding groove 112 can be replaced by a sliding rail, and the sliding rail can be used to guide the sliding of the support 410 or the adjustment assembly 420, and the support 410 or the adjustment assembly 420 can be fastened by the bolt or other fasteners, and the present application does not limit this.
[0053] The adjusting assembly 420 is provided with a clamping piece 430 for clamping the welding gun 310, and the posture of the adjusting assembly 420 is adjustable, so that the adjusting assembly 420 drives the welding gun 310 to move through the clamping piece 430 to change the position of the welding gun 310, so that the welding gun 310 can be stably kept at the welding position of the pipe fitting 700.
[0054] In some embodiments, referring to Figure 2 and Figure 3 The adjusting assembly 420 comprises a first adjusting piece 421, the first adjusting piece 421 is in sliding connection with the support 410 along a third direction, and part of the first adjusting piece 421 extends perpendicularly to the third direction; a second adjusting piece 422, the second adjusting piece 422 is in rotational connection with the first adjusting piece 421 around the extension direction of part of the first adjusting piece 421, and is in sliding connection with the first adjusting piece 421 along the extension direction of part of the first adjusting piece 421; a third adjusting piece 423, the third adjusting piece 423 is in rotational connection with the second adjusting piece 422 around the extension direction of part of the first adjusting piece 421; and a fourth adjusting piece 424, the fourth adjusting piece 424 is in sliding connection with the third adjusting piece 423 along a direction perpendicular to the extension direction of part of the first adjusting piece 421, and the clamping piece 430 is in rotational connection with the fourth adjusting piece 424 around a direction perpendicular to the extension direction of part of the first adjusting piece 421.
[0055] The adjusting assembly 420 is divided into the first adjusting piece 421, the second adjusting piece 422, the third adjusting piece 423, the fourth adjusting piece 424 and the like, and each part is in rotational or sliding connection along different directions, so that the adjusting assembly 420 has degrees of freedom in multiple directions, and the posture adjustment of the clamping piece 430 and the welding gun 310 is more flexible and smooth, so as to improve the efficiency and quality of the welding of the pipe fitting 700.
[0056] Specifically, the first adjusting piece 421 is in sliding connection with the support 410 along the third direction through the sliding groove 112, so as to be close to or away from the table top 110 during sliding. Part of the first adjusting piece 421 extends perpendicularly to the third direction. It can be understood that part of the first adjusting piece 421 extends perpendicularly to the third direction, and also perpendicularly to the extension direction of the sliding groove 112 on the table top 110. For example, in the embodiment, the sliding groove 112 on the table top 110 extends along the first direction (X direction), and part of the first adjusting piece extends along the second direction (Y direction), so that the welding gun support 400 has a larger range of movement. In other embodiments, if the sliding groove 112 on the table top 110 extends along the second direction (Y direction), part of the first adjusting piece can extend along the first direction (X direction), which is not limited in the application.
[0057] The second adjusting member 422 is slidably connected to the first adjusting member 421 along the extension direction of the first adjusting member 421, and the second adjusting member 422 can be rotatably connected to the first adjusting member 421 around the extension direction of the first adjusting member 421. This allows the second adjusting member 422 to slide and rotate relative to the first adjusting member 421 with a large degree of freedom, improving the activity limit of the clamping member 430 in the first and second directions, and flexibly adapting to various specifications of pipe fittings 700.
[0058] The third adjustment member 423 is rotatably connected to the second adjustment member 422 about the extension direction of part of the first adjustment member 421. In this embodiment, the third adjustment member 423 is rotatably connected to the second adjustment member 422 about the second direction (Y direction), which can further improve the movement limit of the clamping member 430 in the first direction.
[0059] The fourth adjusting member 424 is slidably connected to the third adjusting member 423 along the extending direction of the third adjusting member 423. That is, the sliding direction of the fourth adjusting member 424 is perpendicular to the extending direction of part of the first adjusting member 421. The clamping member 430 is disposed on the fourth adjusting member 424, thereby allowing the fourth adjusting member 424 to slide relative to the third adjusting member 423 and causing the clamping member 430 to move relatively closer to or away from the pipe fitting 700 to be welded. In addition, the fourth adjusting member 424 can also be rotatably connected to the third adjusting member 423 around its own axial direction.
[0060] It is understandable that the second adjusting member 422 and the first adjusting member 421, the third adjusting member 423 and the second adjusting member 422, the fourth adjusting member 424 and the third adjusting member 423, and the clamping member 430 and the fourth adjusting member 424 can all be locked or unlocked by conventional locking structures such as fasteners and snap-fits, so that each adjusting member can stably maintain its current posture after adjustment.
[0061] Furthermore, in some embodiments, reference is made to Figure 3 As shown, the clamping member 430 includes a first clamping flap 431 and a second clamping flap 432 disposed opposite to each other. The first clamping flap 431 is radially rotatably connected to the fourth adjusting member 424, thereby allowing the clamping member 430 to rotate radially around the fourth adjusting member 424 to adjust the specific welding angle of the welding torch 310. A clamping space is formed between the first clamping flap 431 and the second clamping flap 432 so that the first clamping flap 431 and the second clamping flap 432 can jointly clamp the welding torch 310.
[0062] Furthermore, refer to Figures 2 to 4As shown, the first adjusting piece 421 comprises: a connecting portion 4211, which is slidingly connected with the supporting piece 410 along the third direction; an extension portion 4212, which is telescopically arranged on the connecting portion 4211; and an extending portion 4213, which is connected with the extension portion 4212 to move along the telescopic direction under the driving of the extension portion 4212, and extends perpendicularly to the third direction and is connected with the second adjusting piece 422.
[0063] It can be understood that the connecting portion 4211 is bent from a plate piece to form three sections arranged in sequence, the second section in the middle is slidingly connected with the supporting piece 410, and the second section of the connecting portion 4211 is arranged obliquely to the supporting piece 410, specifically obliquely to the positioner 200.
[0064] The first section and the third section of the connecting portion 4211 are bent towards the same side of the second section, the first section is fixedly connected with the extension portion 4212 to provide support for the installation of the telescopic section, and the third section stops and positions the extension portion 4212.
[0065] The extension portion 4212 can be a piston device such as a pneumatic cylinder or a hydraulic cylinder, or a motor device such as a telescopic motor, the output end of which can extend and retract along the axial direction, the output end of the extension portion 4212 passes through the first section to extend and retract between the first section and the third section, and the maximum stroke of the extension corresponds to the interval between the first section and the third section.
[0066] The output end of the extension portion 4212 is fitted with the extending portion 4213, the extending direction of the extending portion 4213 is perpendicular to the extending direction of the supporting piece 410, and the extending direction of the extending portion 4213 is perpendicular to the sliding direction of the supporting piece 410 relative to the table top 110, and the second adjusting piece 422 is arranged on the extending portion 4213. Specifically, when the sliding groove 112 on the table top 110 is arranged along the first direction (X direction), the extending portion 4213 extends along the second direction (Y direction), and when the sliding groove 112 on the table top 110 is arranged along the second direction, the extending portion 4213 extends along the first direction.
[0067] In this way, the first adjusting piece 421 can drive the second adjusting piece 422, the third adjusting piece 423 and the fourth adjusting piece 424 to move smoothly when the relative poses of the second adjusting piece 422, the third adjusting piece 423 and the fourth adjusting piece 424 are fixed, so as to realize automatic feeding of the welding rod during welding, and further ensure the welding quality.
[0068] In specific implementation, referring to Figure 1 As shown, the positioner 200, the welding machine 300 and the welding gun support 400 are each arranged in at least two, and each positioner 200, welding machine 300 and welding gun support 400 are arranged one by one.
[0069] It can be understood that the pipe fitting 700 welding generally adopts at least two welding forms such as MAG welding and TIG welding, therefore, at least two sets of positioners 200, welding machines 300 and welding gun supports 400 are correspondingly arranged, wherein the welding machine 300 can be correspondingly selected as a MAG welding machine 300 or a TIG welding machine 300 according to the welding form, in addition, if other welding form is required, a corresponding welding machine 300 can be selected, and a positioner 200 and a welding gun support 400 are arranged to meet different requirements of the pipe fitting 700 welding.
[0070] The protective gas of each welding machine 300 can be connected to the centralized gas supply pipeline arranged in the workshop, for example, the TIG welding can select argon gas with a content of 99.99%, and the MAG welding can select argon gas with a content of 98% and 2% carbon dioxide gas.
[0071] In some embodiments, referring to Figure 1 It is shown that the pipe fitting welding equipment further comprises at least one wire feeder 500, the at least one wire feeder 500 is correspondingly arranged with the at least one welding machine 300, the wire outlet 510 of the wire feeder 500 is connected with the corresponding welding gun support 400, and the welding gun 310 is correspondingly arranged.
[0072] It can be understood that the wire feeder 500 is a device capable of accurately and continuously feeding the welding wire into the welding pool. For example, when the welding form is TIG welding or other welding form requiring welding wire, if the corresponding TIG welding machine 300 does not have a built-in wire feeder 500 for welding wire delivery, an additional wire feeder 500 needs to be arranged to meet the wire feeding requirement in the process of the TIG welding machine 300.
[0073] In order to ensure that the wire feeder 500 can accurately deliver the welding wire, the wire outlet 510 of the wire feeder 500 can be correspondingly arranged with the welding gun 310 on the welding gun support 400. For example, the wire outlet 510 can be connected with the second clamping petal 432 of the clamping part 430 away from the first clamping petal 431 or connected with the third adjusting part 423, which can be clamped or connected, and the wire outlet 510 is correspondingly arranged with the welding gun 310.
[0074] Further, in order to make the control operation of the pipe fitting welding equipment more efficient and centralized, in some embodiments, referring to Figure 1 and Figure 2 It is shown that the pipe fitting welding equipment further comprises at least one controller 600, the welding machine 300, the positioner 200 and the wire feeder 500 are electrically connected with the controller 600, and the controller 600 controls the welding machine 300, the positioner 200 and the wire feeder 500 to start and stop synchronously.
[0075] It can be understood that although the positioner 200, the welding machine 300 and the wire feeder 500 each have a control system, the running angle and the rotation rate of the positioner 200, the pulse frequency and the current size of the welding machine 300, and the wire feeding speed of the wire feeder 500 can be controlled respectively through the control systems of the positioner 200, the welding machine 300 and the wire feeder 500. However, in actual use, after the running parameters of the positioner 200, the welding machine 300 and the wire feeder 500 are set, the positioner 200, the welding machine 300 and the wire feeder 500 need to be started or stopped in sequence. During the starting and stopping of the positioner 200, the welding machine 300 and the wire feeder 500, there is a time interval and a certain starting and stopping sequence. Once the starting and stopping sequence is wrong or the time interval is too long, the positioner 200 may stop rotating while the welding machine 300 is running, or the wire feeder 500 is feeding wire, or the wire feeder 500 is stopped while the positioner 200 is rotating and the welding machine 300 is running, and many other conditions, which will all lead to the quality of the welded pipe 700 being reduced and unnecessary consumption of materials being caused.
[0076] Therefore, the controller 600 can be arranged to be electrically connected with the welding machine 300, the positioner 200 and the wire feeder 500 respectively, so as to realize synchronous starting and stopping control of the welding machine 300, the positioner 200 and the wire feeder 500 through the controller 600, ensure the welding quality of the pipe 700, and avoid waste of materials. The running parameters of the welding machine 300, the positioner 200 and the wire feeder 500 can be set through the control systems of the welding machine 300, the positioner 200 and the wire feeder 500 respectively, so as to reduce the setting cost of the controller 600.
[0077] In addition, the telescopic part 4212 can also be electrically connected with the controller 600, and the telescopic part 4212 drives the welding torch 310 to feed under the control of the controller 600.
[0078] In some embodiments, the controller 600 can also take over the welding machine 300, the positioner 200 and the wire feeder 500 comprehensively, that is, the controller 600 controls the starting and stopping and the running parameters of the welding machine 300, the positioner 200 and the wire feeder 500, so as to realize further automatic control, which is not limited in the present application.
[0079] In addition, as shown in FIG. 6, the controller 600 is arranged to be electrically connected with the welding machine 300, the positioner 200 and the wire feeder 500 respectively. Figure 1
[0080] It can be understood that the controller 600 is provided at least two, and the at least two controllers 600 are provided corresponding to the welding machines 300 of different welding forms, and the corresponding welding machine 300 and positioner 200 can be started alone according to the demand (or the corresponding welding machine 300, positioner 200 and wire feeder 500 can be started alone according to the demand), so that the control of the pipe welding equipment is more diversified and independent, and the operation demand of single set of welding machine 300, positioner 200 and wire feeder 500 or multiple sets of welding machine 300, positioner 200 and wire feeder 500 can be met.
[0081] In addition, in some embodiments, with reference to Figure 1 and Figure 2 It is shown that the notch 111 corresponding to the welding gun support 400 and the positioner 200 is provided on the table top 110 to form an operation position.
[0082] It can be understood that the notch 111 corresponding to the welding gun support 400 and the positioner 200 is provided on the table top 110 to form an operation position, which can be used for the operator to disassemble and assemble the pipe to be welded 700 at the operation position, and adjust the posture of the assembly 420, so as to avoid that the welding gun support 400 and the positioner 200 are too far away from the edge of the table top 110 and are not convenient for the operator to operate, improve the convenience of using the pipe welding equipment, and improve the welding efficiency.
