Description

Technical Field

[0001] The present invention relates to the technical field of welding, in particular to automatic welding equipment integrated with a positioner. Background Art

[0002] The integrated positioner is based on the positioner. It uses a three-jaw chuck, guide rails and pneumatic center to fix the position of the welding torch, thereby realizing the automatic clamping function of the pipe fittings. It can also adjust the position of the workpiece during welding and cooperate with the welding gun to automatically weld the pipe fittings.

[0003] Before welding pipe fittings to plates, the pipe fitting surface needs to be polished. The purpose of polishing is to remove impurities and foreign matter on the pipe fitting surface and reduce the amount of impurities and foreign matter remaining in the weld during welding, which affects the stability of the welding and thus reduces the welding quality. However, when polishing the pipe fitting surface, the surface of the pipe fitting includes the circumferential surface and the end face. Traditional devices generally only polish the circumferential surface of the pipe fitting and ignore the end face of the pipe fitting. After the pipe fitting is welded, foreign matter on the end face of the pipe fitting is sandwiched between the pipe fitting and the plate, which can easily affect the weld, thereby reducing the stability after welding. Summary of the Invention

[0004] The present invention provides an automatic welding device with an integrated positioner, which grinds the circumferential surface of the pipe fitting by a first grinding plate and grinds the end face of the pipe fitting by a second grinding plate, thereby facilitating the simultaneous grinding of the circumferential surface and the end face of the pipe fitting. This solves the problem mentioned in the above background technology that only the circumferential surface of the pipe fitting is ground, while the end face of the pipe fitting is ignored. After the pipe fitting is welded, foreign matter on the end face of the pipe fitting is sandwiched between the pipe fitting and the plate, which can easily affect the weld, thereby reducing the stability after welding.

[0017] The present invention has the following beneficial effects:

[0018] 1. In the automatic welding equipment with integrated positioner, during welding, the conical pressing block is driven by the second servo electric cylinder to move, so that the conical pressing block presses and fixes the tube sheet, and adjusts its position as the positioner body rotates. At the same time, the welding gun is driven by the third servo electric cylinder to move to the position where welding is required, thereby facilitating automatic welding of the tube sheet and saving time and effort.

[0019] In order to further improve the welding quality, before welding, the grinding assembly is moved to the circumferential surface and end surface of the pipe fitting by adjusting the height of the lifting seat and the horizontal position of the ring. Then, by rotating the second column, the overall length between the first column and the second column is adjusted, so that the first grinding plate and the second grinding plate respectively contact the circumferential surface and the end surface of the pipe fitting. The second servo motor drives the rotating ring to rotate inside the ring, so that the first grinding plate and the second grinding plate grind the circumferential surface and the end surface of the pipe fitting at the same time, thereby preventing foreign matter on the end surface of the pipe fitting from being clamped between the pipe fitting and the plate when only the circumferential surface of the pipe fitting is ground, which easily affects the weld, thereby reducing the stability problem after welding.

[0020] 2. In the automatic welding equipment of the integrated positioner, when the second servo motor drives the rotating ring to rotate, it can drive the end of the first slide bar to slide in the annular track groove, so that the first slide bar can perform left and right reciprocating motion, and when the first slide bar performs left and right reciprocating motion, it drives the second slide bar to perform left and right reciprocating motion, and the left and right reciprocating motion of the second slide bar can simultaneously drive the first grinding plate to perform up and down reciprocating motion and drive the second grinding plate to perform left and right reciprocating motion, so that the first grinding plate can rotate and grind the circumferential surface of the pipe fitting while performing up and down rocking grinding, and the second grinding plate can rotate and grind the end surface of the pipe fitting while performing left and right rocking grinding, and cooperate with the positioner body to drive the workpiece to rotate in the opposite direction, thereby changing the grinding position during grinding, making the grinding more sufficient and achieving a good grinding effect;

[0021] 3. In the automatic welding equipment of the integrated positioner, when the first slide bar moves to the right and drives the second slide bar to move to the right, the second trapezoidal block and the second interference rod interfere with each other, which can drive the third grinding plate to move downward along the inclined groove, so that the third grinding plate interferes with the connection between the circumferential surface and the end face of the pipe fitting, so that during rotational grinding, the third grinding plate can fully grind the connection between the circumferential surface and the end face of the pipe fitting, which is convenient for removing some impurities and foreign matter remaining at the connection between the circumferential surface and the end face of the pipe fitting, making the grinding effect worse. In addition, by grinding the connection between the circumferential surface and the end face of the pipe fitting through the third grinding plate, the connection between the circumferential surface and the end face of the pipe fitting can be chamfered, making the connection between the circumferential surface and the end face of the pipe fitting smoother, thereby facilitating the subsequent butt joint work before welding of the pipe fitting.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] For example 1, please refer to Figures 1-9 An automatic welding device with an integrated positioner includes a positioner body 2 for clamping a pipe fitting 1, a side plate 3 fixed to the positioner body 2, a through slot 4 formed on the side plate 3, a lifting seat 5 slidingly provided in the through slot 4 for up and down movement, a circular ring 6 for horizontal movement connected to the lifting seat 5, a rotating ring 7 rotatably provided in the circular ring 6, a grinding assembly 8 provided on the rotating ring 7, and the grinding assembly 8 simultaneously grinds the circumferential surface and end surface of the pipe fitting 1 through circular motion;

[0034] A support frame 40 is fixed to one side of the positioner body 2, and a second servo electric cylinder 41 is fixed to the support frame 40. A conical pressure block 42 is provided at the output end of the second servo electric cylinder 41. A positioning frame 45 is fixed to the output end of the third servo electric cylinder 43. A welding gun 44 is provided on the positioning frame 45.

[0035] The grinding assembly 8 includes a first column 81 fixedly connected to the rotating ring 7, a second column 82 being threadedly connected to the end of the first column 81, a clamping plate 83 being rotatably provided at the end of the second column 82, a telescopic rod 84 being fixed between the clamping plate 83 and the rotating ring 7, and a first grinding plate 85 for grinding the circumferential surface of the pipe fitting 1 and a second grinding plate 86 for grinding the end surface of the pipe fitting 1 being elastically connected to the clamping plate 83;

[0036] A first servo motor 9 is fixed to the top of the side plate 3. A screw rod 10 is rotatably provided in the through slot 4. The output end of the first servo motor 9 is connected to the screw rod 10. The lifting seat 5 is threadedly connected to the screw rod 10. A guide rod 11 is fixed in the through slot 4. The guide rod 11 passes through the lifting seat 5 and is slidably connected to the lifting seat 5.

[0037] A first servo electric cylinder 12 is fixed on the lifting seat 5, and a fixing seat 13 is fixed to the output end of the first servo electric cylinder 12, and the fixing seat 13 is fixedly connected to the ring 6;

[0038] A second servo motor 14 is fixed to the circular ring 6, and a gear 15 is fixed to the output end of the second servo motor 14. A gear ring 16 is fixed to the outer surface of the rotating ring 7, and the gear ring 16 meshes with the gear 15. A limit ring 17 is also fixed to the outer surface of the rotating ring 7, and a limit groove 18 is formed on the inner circumference of the circular ring 6 for the limit ring 17 to rotate.

[0039] A T-shaped slider 19 is fixed to the end of the second column 82, and a hollow boss 20 is fixed to the outer surface of the clamping plate 83. A T-shaped ring groove 21 is formed on the inner wall of the hollow boss 20 for the T-shaped slider 19 to slide.

[0040] In this technical solution, when welding the tube sheet, firstly, the pipe 1 is clamped and fixed by the positioner body 2 (such as Figure 1 As shown), the plate is then placed on the pipe 1, and the conical pressing block 42 is pushed downward by the second servo electric cylinder 41 so that the conical pressing block 42 presses the plate on the pipe 1. Then, the positioning frame 45 is pushed to move by the third servo electric cylinder 43, and the positioning frame 45 drives the welding gun 44 to move, and the welding gun 44 is moved to the position where welding is required. The welding gun 44 is started to weld the welding point. At the same time, the clamped pipe 1 is driven to rotate by the positioner body 2 during welding, so as to adjust the position of the pipe 1 and complete the automatic welding of the tube and sheet. Since the conical pressing block 42 is rotatably connected to the output end of the second servo electric cylinder 41, the rotation of the pipe 1 will not affect the conical pressing block 42 from pressing the plate.

[0041] During welding, there may be foreign matter on the surface of the pipe 1. If it is not cleaned, the welding quality will be affected. Therefore, before welding the pipe 1, the first servo electric cylinder 12 is used to push the fixing seat 13 to move horizontally, and the fixing seat 13 drives the ring 6 to move horizontally, and the center of the ring 6 is moved to be perpendicular to the center of the pipe 1. Then, the first servo motor 9 drives the screw rod 10 to rotate, and the screw rod 10 drives the lifting seat 5 to move downward, and the lifting seat 5 drives the ring 6 to move downward, so that the second grinding plate 86 on the surface of the clamping plate 83 is moved to the end face position of the pipe 1. Then, by rotating the second column 82, the length between the first column 81 and the second column 82 is adjusted (such as Figure 6 As shown) Since the first column 81 and the second column 82 are threadedly connected, a first movable groove 46 for the movement of the first column 81 is provided inside the second column 82. When the second column 82 is rotated, the length between the first column 81 and the second column 82 can be adjusted, thereby adjusting the horizontal position of the clamping plate 83, so that the second grinding plate 86 can be moved to a position in contact with the circumferential surface of the pipe 1. When the second column 82 is rotated, in order to prevent the clamping plate 83 from rotating, a telescopic rod 84 is provided. The telescopic rod 84 includes a first sleeve and a second sleeve that are sleeved with each other. The first sleeve and the second sleeve can slide with each other to complete the telescopic operation, and the T-shaped slider 19 and the T-shaped ring groove 21 (as shown) are provided. Figure 7 As shown in FIG. 2 , when the second column 82 rotates, the T-shaped slider 19 is driven to slide in the T-shaped ring groove 21 , and the telescopic rod 84 is used to restrict the clamping plate 83 so that the clamping plate 83 does not rotate with the second column 82 . By rotating the second column 82 , the position of the clamping plate 83 is adjusted so that the first grinding plate 85 contacts the end face of the pipe 1 , and the second grinding plate 86 contacts the circumferential surface of the pipe 1 ;

[0042] When the pipe fitting 1 is being polished, the pipe fitting 1 is rotated by starting the positioner body 2. The positioner body 2 is a prior art and can adjust different positions by rotation. This application will not describe it in detail. At the same time, the second servo motor 14 is started to drive the gear 15 to rotate. The gear 15 drives the rotating ring 7 to rotate through the gear ring 16, so that the rotating ring 7 rotates in the opposite direction to the pipe fitting 1. The rotating ring 7 rotates, driving the first polishing plate 85 and the second polishing plate 86 to polish the circumferential surface and end face of the pipe fitting 1 respectively. After polishing is completed, the first servo electric cylinder 12 and the first servo motor 9 are reset, and the ring 6 is moved to one side of the pipe fitting 1 for reset. After polishing, the above-mentioned welding work is performed, thereby improving the welding quality between the tube plates.

[0043] In this technical solution, the automatic welding equipment also includes a display and adjustment device of the prior art. The display and adjustment device is arranged on one side of the automatic welding equipment. It is not an innovation of this application and will not be described in detail. The display and adjustment device has display function, adjustment function and storage function. In the pipeline groove grinding link, it can display the degree of the grinding groove and can be manually adjusted; in the pipeline docking link, it can display the distance between the docking ports and can be manually adjusted; during the entire welding process, the changes in parameters such as current and voltage during the welding process can be recorded and copied for later query.

[0044] In the second embodiment, since the first grinding plate 85 and the second grinding plate 86 only rotate in a circular motion relative to the pipe 1 when grinding the pipe 1, it is equivalent to grinding a position of the pipe 1 in a circular motion at one position on the first grinding plate 85 and the second grinding plate 86. In this process, if the grinding effect of one or several positions is not good, there will be insufficient grinding, resulting in the inability to make up for the defect of poor grinding effect. To solve this problem, this embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figures 1-9 An annular track groove 22 is opened in the ring 6, and a first slide rod 23 is slidably arranged in the annular track groove 22. The first slide rod 23 is slidably connected to the rotating ring 7 and the first column 81. The end of the first slide rod 23 is threadedly connected to the second slide rod 24. The second slide rod 24 passes through the card plate 83 and is connected to the first grinding plate 85. One side of the second slide rod 24 is elastically connected to the second grinding plate 86;

[0045] A square card slot 25 is formed inside the second upright post 82, and a square card rod 26 is fixed to the outer surface of the second slide bar 24. The square card rod 26 is slidably inserted into the square card slot 25.

[0046] The clamping plate 83 defines a receiving groove 27 for sliding the first grinding plate 85 and the second grinding plate 86. A first trapezoidal block 28 is fixed to the outer surface of the second slide bar 24. A first interference rod 29 is fixed to the first grinding plate 85 and contacts the first trapezoidal block 28. A first guide groove 30 is defined in the first trapezoidal block 28 for sliding the first interference rod 29.

[0047] A second guide groove 32 is defined in the clamping plate 83 , and a protrusion 31 is fixed to the first polishing plate 85 , and the protrusion 31 is slidably disposed in the second guide groove 32 ;

[0048] In the present technical solution, when adjusting the length between the first column 81 and the second column 82, the second column 82 is rotated. When the second column 82 rotates, the square card slot 25 restricts the square card rod 26, so that the square card rod 26 rotates with the second column 82. The rotation of the square card rod 26 drives the second slide bar 24 to rotate. Since the second slide bar 24 is threadedly connected to the first slide bar 23, the second slide bar 24 is provided with a second movable groove 47 (such as Figure 7 As shown), when the second slide bar 24 is driven to rotate, the length between the first slide bar 23 and the second slide bar 24 can be adjusted, thereby coordinating the extension and contraction of the first column 81 and the second column 82 to change the length accordingly;

[0049] Then, when the second servo motor 14 drives the gear 15 to rotate, and the gear 15 drives the rotating ring 7 to rotate through the gear ring 16, the end of the first slide rod 23 is provided with a first spherical protrusion 231, so that the first spherical protrusion 231 slides in the annular track groove 22, and the annular track groove 22 is set as a wave-shaped groove (such as Figure 9 As shown), when the first spherical protrusion 231 slides in the annular track groove 22, it can drive the first slide bar 23 to reciprocate left and right. The first slide bar 23 reciprocates left and right, driving the second slide bar 24 to reciprocate left and right. At the same time, the second slide bar 24 drives the square card rod 26 to slide in the square card groove 25 (as shown). Figure 7 As shown), when the second slide bar 24 reciprocates left and right, it drives the second grinding plate 86 to reciprocate left and right in the receiving groove 27, so that the second grinding plate 86 rotates and grinds the end surface of the pipe 1 while shaking left and right; when the second slide bar 24 moves to the right, it drives the first trapezoidal block 28 to move right, and when the first trapezoidal block 28 moves to the right, the first contact rod 29 slides from right to left along the first guide groove 30 (as shown). Figure 8 The first grinding plate 85 is prevented from sliding out of the first guide groove 30, thereby limiting the position of the first interference rod 29. The first interference rod 29 moves downward, driving the first grinding plate 85 to move downward, and the first grinding plate 85 drives the protrusion 31 to slide in the second guide groove 32, so that the first grinding plate 85 can only slide up and down. When the second slide bar 24 moves to the left, it drives the first trapezoidal block 28 to move left, and the first interference rod 29 slides from left to right along the first guide groove 30, so that the first interference rod 29 pulls the first grinding plate 85 to reset, so that when the second slide bar 24 reciprocates left and right, it drives the first grinding plate 85 to reciprocate up and down, so that the first grinding plate 85 rotates and grinds the circumferential surface of the pipe fitting 1 while shaking and grinding it up and down, which has a better grinding effect.

[0050] In the third embodiment, when the first grinding plate 85 and the second grinding plate 86 grind the circumferential surface and the end surface of the pipe 1, some foreign matter will remain at the connection between the circumferential surface and the end surface of the pipe 1, which will deteriorate the grinding effect. In addition, when welding, the connection between the circumferential surface and the end surface of the pipe 1 is welded to another workpiece. If the grinding effect at the connection between the circumferential surface and the end surface of the pipe 1 is not good, it will also affect the welding effect. To solve this problem, this embodiment is an improvement made on the basis of the second embodiment. For details, please refer to Figures 1-9 An inclined groove 33 is provided in the accommodating groove 27, and a guide plate 34 is slidingly provided inside the inclined groove 33. A connecting rod 35 is fixed on the guide plate 34, and a third grinding plate 36 for grinding the edges and corners of the pipe 1 is fixed on the connecting rod 35. A second spring 37 is fixed between the inner wall of the inclined groove 33 and the guide plate 34, a second trapezoidal block 38 is fixed to the end of the second slide rod 24, and a second interference rod 39 in contact with the second trapezoidal block 38 is fixed on the third grinding plate 36;

[0051] In this technical solution, (such as Figure 8 As shown in the figure, when the second slide bar 24 moves to the right, it drives the second trapezoidal block 38 to move to the right, and the second trapezoidal block 38 moves to the right to conflict with the second conflicting rod 39, causing the second conflicting rod 39 to move downward. The second conflicting rod 39 applies force to the third grinding plate 36, prompting the third grinding plate 36 to drive the guide plate 34 to slide downward in the inclined groove 33 through the connecting rod 35, so that the second spring 37 is stretched and stored until the surface of the third grinding plate 36 conflicts with the connection between the circumferential surface and the end face of the pipe fitting 1. At this time, the second conflicting rod 39 moves along the inclined surface of the second trapezoidal block 38 to the lower surface of the second trapezoidal block 38. When the second slide bar 24 continues to move to the right, the second conflicting rod 39 The second spring 37 releases its force and pulls the guide plate 34 upward in the inclined groove 33, thereby driving the second interference rod 39 and the third grinding plate 36 to return to their original position.

[0052] The guide plate 34 and the inclined groove 33 are both set to a T-shaped structure, so that the guide plate 34 is confined in the inclined groove 33, so that the guide plate 34 can only slide up and down along the inclined groove 33 and will not move outward, so that the guide plate 34 will not slide out of the inclined groove 33.

[0053] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
