Description

Technical Field

[0001] The invention relates to the technical field of welding, and in particular to welding equipment for processing impellers used for processing fan accessories. Background Art

[0002] Fan impeller is a kind of fan accessory. Fan impeller welding mainly involves welding the impeller blades to the blade disk.

[0003] During the impeller welding process, it is particularly important to control the equal spacing between the blades. If the blade spacing is uneven, it will not only cause uneven mass distribution and thus cause vibration during operation, but also cause irregular disturbances when the airflow passes through, increasing noise. The blade spacing control requires not only the control of the vertical spacing between blades (based on the radial direction of the blade disk), but also the control of the circumferential spacing between blades based on the blade disk, where: (1) Because it is a circumferential spacing, the measurement method is too complicated, and there is no corresponding measurement tool. There is a large deviation when relying on traditional mechanical means to measure; (2) For fixed circumferential spacing, a fixed mold or tooling is usually used. However, the structural dimensions of the mold or tooling are single and are not suitable for the welding requirements of fan impellers with multi-size structures.

[0004] In order to solve the above problems, we propose a welding device for impeller processing for fan accessories processing. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a welding device for processing impellers for fan accessories, which has advantages such as circumferential spacing adjustment and can effectively solve the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a welding device for processing impellers for processing fan accessories, comprising a circumferential spacing adjustment mechanism and a plurality of chucks; The circumferential spacing adjustment mechanism includes a sealing ring frame, a plurality of sliders are placed inside the sealing ring frame, and a sliding seat corresponding to the plurality of sliders is attached to the outside of the sealing ring frame, the sliding seat is connected to the outer wall of the sealing ring frame and slides relatively thereto, and the slider is magnetically attracted to the corresponding sliding seat; At least one fluid inlet and one fluid outlet are provided on the sealing ring frame, and one-way valves are provided inside the fluid inlet and the fluid outlet; The number of the chucks corresponds to the number of the slide seat 1 and the sliding block, and the chucks are connected to the corresponding slide seat 1.

[0007] As a preference, those skilled in the art will appreciate that when the blade to be processed is as follows Figure 1When the curved blade is shown, a multi-jaw chuck should be used to better clamp the blade.

[0008] Preferably, the structure of the slider is compatible with that of the sealing ring frame. In order to enable the slider to slide smoothly inside the sealing ring frame, a sleeve of flexible material, such as rubber material, is installed at the fitting portion of the slider and the sealing ring frame. While ensuring a good seal between the slider and the sealing ring frame, the slider can slide normally under the action of external pressure.

[0009] Preferably, the magnet is embedded in the slider and fixedly connected thereto. To ensure the overall lightweight of the equipment and to prevent the magnet from excessive external interference, the welding equipment, except for necessary structural components, is made of non-metallic materials or lightweight non-magnetic alloy materials.

[0010] Preferably, the slide seat is provided with a ball bearing, and a groove is provided on the sealing ring frame at a position corresponding to the ball bearing.

[0011] Preferably, two grooves are provided, which are divided into an inner ring and an outer ring based on the geometric center of the sealing ring frame, so as to ensure that the sliding seat can slide in the circumferential direction of the sealing ring frame without deviation.

[0012] Preferably, the sealing ring frame is open on one side, and is matched with a cover plate 1, so that multiple sliders can be disassembled and assembled at the same time.

[0013] Preferably, the fluid inlet is externally connected to a fluid supply device to supply fluid to the interior of the sealing ring frame.

[0014] Preferably, a groove is provided on the slider so that when the slider moves to face the fluid inlet, the fluid inlet and the groove are on the same axial direction. In this state, because the fluid is not flowing to the left or right side of the slider, the possibility of the slider currently facing the fluid inlet being offset during the fluid filling process is avoided to the greatest extent.

[0015] Preferably, the fluid inlet and the fluid outlet are closely adjacent to each other on the sealing ring frame, and the fluid outlet is opened on the side of the sealing ring frame which is away from the moving direction of the slider. This is different from the manner in which the fluid outlet is opened at any section of the sealing ring frame. For example, when the fluid outlet is opened in the middle section of the sealing ring frame, if the slider moves there, it will cause the space between the sliders to not be a closed space, and the fluid will flow out from the fluid outlet, causing abnormal movement of the slider. Therefore, when the fluid outlet is opened adjacent to the fluid inlet, the utilization rate of the entire section of the sealing ring frame can be maximized.

[0016] Preferably, a placement opening for placing the sliding block is provided on the sealing ring frame, and a second cover plate is provided in conjunction with the placement opening.

[0017] Preferably, the structure of the cover plate 2 matches that of the placement opening, and the cover plate 2 is detachably connected to the sealing ring frame, and the structure of the placement opening matches that of the slider.

[0018] Preferably, the placement port is positioned based on the following principles: when a slider coaxial with the fluid inlet is placed inside the sealing ring frame, there is no gap between the slider placed later and the slider coaxial with the fluid inlet. In this state, after the slider is placed into the sealing ring frame through the placement port, there is no need to move the sliders again, thereby reducing the movement operation of the slider and indirectly avoiding operational errors.

[0019] Preferably, a plurality of fluid inlets are equidistantly provided in an annular shape based on the geometric center of the sealing ring frame. Thus, as a commonly used implementation, the spacing between the plurality of fluid inlets is equal to the circumferential spacing between the blades to be welded. In the process of adjusting the plurality of sliders, the plurality of sliders are first moved to a state without gaps, and then the last slider in the slider moving direction is moved to be opposite to the fluid inlet, and then the interior of the sealing ring frame is filled with fluid through the fluid inlet, so that the slider before this slider moves to the fluid inlet that is closest to this fluid inlet in the slider moving direction, and this operation step is repeated, which can replace the method of always calculating the filling amount of the fluid.

[0020] Preferably, when the fluid filled into the sealing ring frame is liquid, the placement port pre-opened on the sealing ring frame is located at the upper end of the sealing ring frame, thereby preventing the fluid inside the sealing ring frame from flowing out from the placement port during the placement of the slider.

[0021] Preferably, a radial spacing adjustment mechanism is provided between the chuck and the circumferential spacing adjustment mechanism, for adjusting the radial position of the chuck based on the sealing ring frame.

[0022] Preferably, the radial spacing adjustment mechanism may be a mechanism of a screw and a bolt, or a slider and a slide rail. After the adjustment is completed, the bolt or the slider should be tightened to prevent the chuck from loosening by itself.

[0023] Preferably, the radial spacing adjustment mechanism includes a slide seat 2 fixedly connected to the chuck, and a slide is cooperated with the slide seat 2. The radial spacing adjustment mechanism also includes a movable seat and a base. A connecting rod is movably connected between the slide seat 2 and the movable seat. A screw is arranged between the movable seat and the base. The screw is threadedly connected to the movable seat and rotatably connected to the base. The slide is fixedly connected to the corresponding slide seat 1.

[0024] Compared with the prior art, the present invention provides a welding device for impeller processing for fan accessories processing, which has the following beneficial effects: The impeller welding equipment for processing fan accessories is characterized in that sliders corresponding to the number of blades to be welded are placed in a sealing ring frame, the circumferential spacing between the sliders based on the sealing ring frame is equal to the spacing between two adjacent blades to be welded, the interior of the sealing ring frame is filled with fluid through a fluid inlet, and a fixed amount of fluid is repeatedly filled to make the spacing between the sliders equal, and a slider seat 1 that is magnetically attracted to the slider is used to drive the position of the blades fixed to the chuck to be adjusted by the slider seat 1, and the chuck connected to the circumferential spacing adjustment mechanism can clamp and weld blades with different circumferential spacings by changing the amount of fluid between the sliders, so that the spacing of the blades is mapped by the fluid capacity, which not only effectively improves the work efficiency, but also reduces the uncertainty caused by human operation, can reduce the error caused by manual adjustment, and improve the consistency and quality of welding; Before welding, two of the chucks can be moved together with the slide to two adjacent blades of the finished fan impeller. After the spacing between the two chucks is determined, the two chucks can be moved to the two corresponding slides without gap. During the movement of the two slides, the fluid capacity inside the sealing ring frame changes. The discharged fluid capacity is measured to obtain the filled fluid capacity in the subsequent processing process, which is more in line with the development concept of contemporary automated control.

[0033] In order to make the technical means, creative features, objectives and functional effects of the present invention easy to understand, the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0034] [Example 1] In order to address the shortcomings of the existing technology, such as Figure 1 As shown, the present invention provides a welding device for impeller processing for fan accessories processing. It can be understood by those skilled in the art that when the blade 001 to be processed is as follows Figure 1 When the arc-shaped blade is shown, in order to better clamp the blade 001, a multi-jaw chuck should be used. In this embodiment, the chuck 23 is fixedly connected to the corresponding slide 14.

[0035] It should be noted that, during the welding of the fan impeller, the circumferential spacing adjustment mechanism 1 is adjusted according to the number of blades 001 to be welded, and after the circumferential spacing adjustment mechanism 1 is adjusted, a plurality of blades 001 are fixed together on a plurality of chucks 23; During the welding process of the blade 001, the welding equipment as a whole is placed on the hub of the blade disk 002 based on the support 3 for fixing. The support 3 can adopt a telescopic rod to adapt to the welding requirements of blades 001 of different heights.

[0036] Specifically, Figure 2 , 3 As shown, a circumferential spacing adjustment mechanism 1 in a welding device for processing impellers for processing fan accessories, a slider 15 matches the structure of a sealing ring frame 11, and in order to enable the slider 15 to slide smoothly inside the sealing ring frame 11, a sleeve of a flexible material, such as a rubber material, is installed on the slider 15 at the contacting portion with the sealing ring frame 11, so that the slider 15 can slide normally under the action of external pressure while ensuring a good seal between the slider 15 and the sealing ring frame 11; The magnet 151 is embedded in the slider 15 and fixedly connected thereto. To ensure the overall lightweight of the equipment and to prevent the magnet 151 from being subjected to excessive external interference, the welding equipment, except for necessary structural components, is made of non-metallic materials or lightweight non-magnetic alloy materials; the slide seat 14 is attached with a ball 141, and a groove 13 is provided on the sealing ring frame 11 at a position corresponding to the ball 141, and the slide seat 14 is detachably connected to the sealing ring frame 11; There are two grooves 13, which are divided into an inner ring and an outer ring based on the geometric center of the sealing ring frame 11, so as to ensure that the sliding seat 14 can slide in the circumferential direction of the sealing ring frame 11 without deviation; the sealing ring frame 11 is single-sided open, and based on this, it is matched with a cover plate 12, so that multiple sliders 15 can be disassembled and assembled at the same time; the fluid inlet 111 is connected to an external fluid supply device to supply fluid to the inside of the sealing ring frame 11.

[0037] It should be noted that the present invention is a welding device for impeller processing for fan accessories processing. By setting a circumferential spacing adjustment mechanism 1, before welding the blade 001 and the blade disk 002, the corresponding number of slide seats 14 and sliders 15 are selected according to the number of blades 001 to be welded. The redundant slide seats 14 and sliders 15 that are not put into use can be removed from the cover plate 12 and the sealing ring frame 11, and then several groups of slide seats 14 and sliders 15 are adjusted equidistantly; In the process of adjusting the spacing between multiple sets of slide seats 14 and slide blocks 15, Figure 4 The structural state shown is the initial state before the isometric adjustment. To ensure the accuracy of the spacing adjustment of multiple sets of slide seats 14 and sliders 15, multiple slide seats 14 are first moved to the corresponding sliders 15 with zero gap, and the last slide seat 14 in the moving direction is moved to face the fluid inlet 111. Then, a certain volume of fluid is filled into the interior of the sealing ring frame 11 through the fluid inlet 111. As the fluid is injected, the spacing between the sliders 15 changes. During the fluid injection process, the slider 15 facing the fluid inlet 111 needs to be kept stationary by controlling the external slide seat 14. After the distance between the slide 14 and the slide 14 closest to it is appropriate, the slide 14 farthest from the slide 14 is moved around the sealing ring frame 11 for one circle until there is zero gap with the slide 14, and is continuously moved to the original position of the slide 14, and then the interior of the sealing ring frame 11 is filled with fluid through the fluid inlet 111, and the above operation is repeated until the distances between the multiple slides 14 are consistent.

[0038] By adjusting the spacing between multiple sliders 15 in the sealing ring frame 11 equally, the corresponding slider 14 located outside the sealing ring frame 11 is driven to move synchronously during the movement of the slider 15. In this embodiment, the slider 14 can be installed before or after the slider 15 is adjusted.

[0039] After that, the plurality of blades 001 are fixed to the chuck 23 and then welding can be performed.

[0040] In this embodiment, in order to accurately obtain the spacing between the two blades 001 to be welded, before that, a fan impeller after welding can be used as a finished product, and two clamps 23 can be respectively fixed to two adjacent blades of the fan impeller, and the spacing is kept fixed, and the slider 15 corresponding to one of the clamps 23 is moved to be opposite to the fluid outlet 112, and then the sliders 15 corresponding to the two blades are moved until there is no gap. In this process, the volume of the discharged fluid is measured to obtain the volume of the fluid that should be filled in a subsequent single time; As described above, during the process of fluid discharge, one slide 14 should be moved until the corresponding slider 15 is opposite to the fluid outlet 112, and the position of this slide 14 should be maintained stationary, and then the other slide 14 is moved so that the slider 15 corresponding to the other slide 14 moves relative to the stationary slide 14, during which the fluid is discharged through the fluid outlet 112.

[0041] Among them, the volume of multiple fillings of fluid is consistent and is precisely controlled by the solenoid valve on the external fluid supply equipment. The fluid supply equipment includes gas supply equipment and liquid supply equipment, such as an air pump or a water pump. A pressure gauge or flow meter is installed on the air pump or the water pump to monitor the supplied fluid in real time.

[0042] It is worth mentioning that, by placing sliders 15 corresponding to the number of blades 001 to be welded in the sealing ring frame 11, the circumferential spacing between the sliders 15 and the sliders 15 based on the sealing ring frame 11 is equal to the spacing between two adjacent blades 001 to be welded, the fluid is filled into the interior of the sealing ring frame 11 through the fluid inlet 111, and the operation of filling a certain amount of fluid is repeated, so that the spacing between the sliders 15 and the sliders 15 is equal, and the slider 14 that is magnetically attracted to the slider 15 is used to drive the slider 14 to adjust the position of the blade 001 fixed to the chuck 23, and by changing the amount of fluid between the sliders 15 and the sliders 15, the chuck 23 connected to the circumferential spacing adjustment mechanism 1 can clamp and weld the blades 001 with different circumferential spacings, so that the spacing of the blades 001 is mapped by the fluid capacity, which not only effectively improves the work efficiency, but also reduces the uncertainty caused by human operation, can reduce the error caused by manual adjustment, and improve the consistency and quality of welding; Before welding, two of the chucks 23 can be moved together with the slide 14 to two adjacent blades of the finished fan impeller. After the spacing between the two chucks 23 is determined, the two chucks 23 are moved to the two corresponding slides 15 without gap. During the movement of the two slides 15, the fluid capacity inside the sealing ring frame 11 changes. The discharged fluid capacity is measured to obtain the filled fluid capacity in the subsequent processing process, which is more in line with the development concept of contemporary automated control.

[0043] As a preferred embodiment, Figure 1~2 In the structural state shown, a plurality of fluid inlets 111 are equidistantly provided on the sealing ring frame 11 based on its geometric center ring. Thus, as a commonly used embodiment, the spacing of the plurality of fluid inlets 111 is equal to the circumferential spacing position of the blades 001 to be welded. In the process of adjusting the plurality of sliders 15, the plurality of sliders 15 are first moved to no gap, and then the last slider 15 in the moving direction of the slider 15 is moved to be opposite to the fluid inlet 111, and then the interior of the sealing ring frame 11 is filled with fluid through the fluid inlet 111, so that the previous slider 15 of this slider 15 is moved to the fluid inlet 111 that is most adjacent to this fluid inlet 111 in the moving direction of the slider 15. Repeating this operation step can replace the method of always calculating the filling amount of the fluid. A groove 152 is provided on the slider 15, so that when the slider 15 moves to face the fluid inlet 111, the fluid inlet 111 and the groove 152 are on the same axial direction. In this state, because the fluid does not flow to the left or right side of the slider 15, the possibility of the slider 15 currently facing the fluid inlet 111 being offset during the fluid filling process is avoided to the greatest extent.

[0044] In addition, it should be noted that Figure 4In the structural state shown, the fluid inlet 111 and the fluid outlet 112 are closely adjacent to each other on the sealing ring frame 11, and the fluid outlet 112 is opened on the sealing ring frame 11 on the side of the fluid inlet 111 away from the moving direction of the slider 15, which is different from the manner in which the fluid outlet 112 is opened at any section of the sealing ring frame 11. For example, when the fluid outlet 112 is opened in the middle section of the sealing ring frame 11, if the slider 15 moves there, it will cause the space between the sliders 15 to be not a closed space, and the fluid will flow out from the fluid outlet 112, causing abnormal movement of the slider 15. Therefore, when the fluid outlet 112 is opened adjacent to the fluid inlet 111, the utilization rate of the entire section of the sealing ring frame 11 can be maximized.

[0045] [Example 2] Based on the above-mentioned embodiment 1, as another preferred adjustment rule of the slide 14, this embodiment is proposed to further improve the structure of the circumferential spacing adjustment mechanism 1: Specifically, Figure 4 As shown, a circumferential spacing adjustment mechanism 1 for a welding device for impeller processing for fan accessories processing is provided on a sealing ring frame 11, and a placement opening 113 for placing a slider 15 is provided, and a second cover plate 114 is matched with the placement opening 113; the structure of the second cover plate 114 and the placement opening 113 is matched, and the second cover plate 114 and the sealing ring frame 11 are detachably connected, and the placement opening 113 and the structure of the slider 15 are matched; The position of the placement opening 113 is provided based on the following principle: when a slider 15 coaxial with the fluid inlet 111 is placed inside the sealing ring frame 11, there is no gap between the slider 15 placed later and the slider 15 coaxial with the fluid inlet 111. In this state, after the slider 15 is placed into the sealing ring frame 11 through the placement opening 113, there is no need to move the sliders 15 again, thereby reducing the movement operation of the slider 15 and indirectly avoiding operational errors.

[0046] It should be noted that the present invention is a welding device for impeller processing for fan accessories. Through the circumferential spacing adjustment mechanism 1, in the process of adjusting the spacing of multiple slides 14, only two sliders 15 are placed in advance inside the sealing ring frame 11, and the last slider 15 in the moving direction of the slide 14 is moved to be opposite to the fluid inlet 111, and then the fluid is filled into the sealing ring frame 11 through the fluid inlet 111, so that the spacing between the two sliders 15 changes; After the spacing between the two sliders 15 is adjusted, the second cover plate 114 is removed, and the next slider 15 is placed, and then the second cover plate 114 is closed to the placement port 113, and the newly placed slider 15 is moved to the original position of the slider 15 facing the fluid inlet 111, and the slider 15 originally facing the fluid inlet 111 is moved until there is no gap with the slider 15 currently facing the fluid inlet 111, and then the fluid is filled into the interior of the sealing ring frame 11 through the fluid inlet 111, and this step is repeated to achieve the spacing adjustment of multiple sliders 15.

[0047] When the fluid filled into the sealing ring frame 11 is liquid, the placement port 113 pre-opened on the sealing ring frame 11 is located at the upper end of the sealing ring frame 11, so as to prevent the fluid inside the sealing ring frame 11 from flowing out from the placement port 113 during the placement of the slider 15.

[0048] [Example 3] In order to ensure that the spacing between the blades 001 is close to equal to the greatest extent, in the process of welding the blades 001, it is not limited to controlling the circumferential spacing of the multiple blades 001 to be equal, and the radial spacing between the multiple blades 001 should also be equal. For this reason, based on the above-mentioned embodiment 1 or 2, this embodiment is proposed: A welding device for impeller processing for fan accessories is provided, wherein a radial spacing adjustment mechanism 2 is provided between a chuck 23 and a circumferential spacing adjustment mechanism 1, for adjusting the radial position of the chuck 23 based on a sealing ring frame 11; the radial spacing adjustment mechanism can be a mechanism of adjustment type such as a screw and a bolt, or a slider and a slide rail, and after the adjustment is completed, in order to prevent the chuck 23 from loosening by itself, the bolts or the slider should be tightened.

[0049] Specifically, Figures 5 to 7 As shown, a radial spacing adjustment mechanism 2 for a welding device for impeller processing for fan accessories processing, the radial spacing adjustment mechanism 2 includes a slide seat 22 fixedly connected to a chuck 23, and a slide 21 is matched with the slide seat 22, the radial spacing adjustment mechanism 2 also includes a movable seat 25 and a base 26, a connecting rod 24 is movably connected between the slide seat 22 and the movable seat 25, a screw 27 is provided between the movable seat 25 and the base 26, the screw 27 is threadedly connected to the movable seat 25 and rotatably connected to the base 26, and the slide 21 is fixedly connected to the corresponding slide seat 14; The slide 21 is connected to the base 26 via a ring 261 , and the movable seat 25 has a similar structure to the base 26 , so that the connecting rod 24 can rotate and slide relatively with the ring 261 on the movable seat 25 .

[0050] It should be noted that the present invention is a welding device for impeller processing for fan accessories processing, and the radial spacing of multiple chucks 23 is adjusted by the radial spacing adjustment mechanism 2 before or after the circumferential spacing adjustment mechanism 1 is adjusted, and the movable seat 25 moves based on the axial direction of the screw 27 during the rotation of the screw 27, and then the corresponding slide seat 22 is driven by the connecting rod 24 to slide relative to the corresponding slide 21, thereby realizing the adjustment of the radial spacing of multiple chucks 23; In order to prevent the screw rod 27 from rotating on its own, a nut 28 is provided between the screw rod 27 and the movable seat 25 . After the adjustment is completed, the nut 28 should be tightened until it fits tightly with the movable seat 25 .

[0051] In this embodiment, in order to enable the radial spacing adjustment mechanism 2 to perform circumferential adjustment corresponding to the circumferential spacing adjustment mechanism 1 , the plurality of slides 21 and the base 26 as well as the plurality of connecting rods 24 and the movable seat 25 are connected via a ring 261 .

[0052] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for illustrating the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed for protection.
