Description

Technical Field

[0001] The utility model belongs to the technical field of welding tools, and in particular relates to a welding positioning device and corresponding welding equipment. Background Art

[0002] During the welding process, the materials to be welded (the first device and the second device) are usually docked and positioned first, and then the welding operation is performed manually by holding the welding device. However, in the existing welding positioning device, the positioning seat used to position the materials to be welded is completely fixed. When positioning the materials to be welded, the materials to be welded cannot rotate relatively, which requires manual operation around the part to be welded to complete all-round welding; this method is cumbersome to operate, inefficient, and the consistency of the weld points is difficult to ensure. Moreover, the fixed positioning seat is not easy to disassemble and replace to adapt to different materials to be welded.

[0003] In addition, the materials to be welded (the first device, the second device and the solder) can be butted and positioned by the welding positioning device before being sent to the welding equipment for welding. However, when the existing welding positioning device positions the materials to be welded, the materials to be welded cannot rotate relatively, and consistent all-round welding cannot be achieved in the welding equipment.

[0004] Furthermore, the existing welding equipment has limited welding stations, and manual loading and unloading of materials is still required at the welding stations; if the daily output requirements are high, multiple devices need to be invested, which requires a large investment and high labor costs.

[0035] Embodiment 1

[0036] like Figure 1 As shown, the first embodiment provides a welding positioning device, including a substrate 10, a positioning seat 20, and a bearing 30; the positioning seat 20 is relatively rotatably arranged on the substrate 10 through the bearing 30; a welding material hole 21 is opened on the positioning seat 20 for positioning the first device to be welded. Preferably, the shape of the welding material hole 21 matches the shape of the first device to be welded.

[0037] Specifically, a positioning hole 11 is formed on the upper surface of the substrate 10, and the bearing 30 is disposed in the positioning hole 11, and the outer ring 31 of the bearing 30 is fixedly connected (for example, by interference fit or snap fit) to the inner side wall of the positioning hole 11, and the inner ring 32 of the bearing 30 is fixedly connected (for example, by interference fit or snap fit) to the lower part of the positioning seat 20. In this way, when the inner ring 32 of the bearing 30 rotates relative to the outer ring 32 with the aid of the ball 33, the positioning seat 20 can rotate relative to the substrate 10.

[0038] Take the welding of the air-conditioning filter and the pipeline fitting as an example: the air-conditioning filter is taken as the first component to be welded, and the pipeline fitting is taken as the first component to be welded; now the welding part and the solder ring of the pipeline fitting are connected to the welding part of the air-conditioning filter, and then the air-conditioning filter is placed in the material hole 21 to be welded, which is equivalent to positioning the entire material to be welded including the air-conditioning filter, the pipeline fitting and the solder ring in the material hole 21 to be welded.

[0039] During specific welding, the welding positioning device provided in the first embodiment needs to cooperate with the high-temperature welding device, that is, the welding portion between the first device and the second device and the solder ring are heated by the high-temperature welding device to complete the welding. In this case, since the positioning seat 20 is relatively rotatably arranged on the substrate 10 through the bearing 30, during the welding process, the positioning seat 20 and the entire material to be welded arranged thereon can rotate relative to the substrate 10, so that the welding portion between the first device and the second device and the solder ring can be heated in the circumferential direction, achieving a better welding effect.

[0040] Combination Figure 1 and Figure 2 As shown, in order to ensure that the positioning seat 20 will not axially separate from the substrate 10 when rotating relative to the substrate 10, this embodiment uses a limiter 40 to limit the axial movement of the positioning seat 20 relative to the substrate 10. The limiter 40 can be a screw, whose screw portion passes through the substrate 10 and is connected to the lower part of the positioning seat 20, and whose nut portion is limited to the lower surface of the substrate 10, so as to axially lock the positioning seat 20 on the substrate 10 from below the substrate 10. A connecting portion 25 is protrudingly provided at the lower part of the positioning seat 20, and a screw hole 251 is opened on the connecting portion 25 for screwing with the screw serving as the limiter 40; in addition, the outer periphery of the connecting portion 25 is used to be embedded in the inner hole of the inner ring 32 of the bearing 30 and fixedly connected to the inner ring 32.

[0041] It is understandable that the limit member 40 can be other structures, for example: a circumferential groove opened in the part of the positioning seat 20 located above the substrate 10 and a pin arranged above the substrate 10 that can be embedded in the circumferential groove; or, a circumferential flange arranged in the part of the positioning seat 20 located above the substrate 10 and a stop member arranged above the substrate 10 that can stop the axial movement of the circumferential flange.

[0042] Continue to see Figure 2 The outer periphery of the positioning seat 20 is provided with an embossed pattern 26, which is used to increase the roughness of the outer periphery of the positioning seat 20, so that the friction force acting on the outer periphery of the positioning seat 20 can easily drive the positioning seat 20 to rotate.

[0043] Combination Figure 1 and Figure 2 As shown, three spring plunger holes 22 are provided at equal angles in the positioning seat 20, and a spring plunger 23 facing the material hole 21 to be welded is provided in each spring plunger hole 22. The spring plunger 23 is used to press the first component to be welded in the material hole 21 to prevent it from tilting or shaking. The spring plunger holes 22 and the spring plungers 23 can be provided in one group, two groups or more groups.

[0044] In the above-mentioned first embodiment, a plurality of positioning seats 20 are rotatably arranged on the substrate 10 via bearings 30 respectively. The substrate 10 is movably arranged. The plurality of positioning seats 20 are moved one by one or in batches to the welding stations of the high-temperature welding device through the movement of the substrate.

[0045] Embodiment 2

[0046] Combination Figure 3 As shown, the second embodiment also provides a welding positioning device. The difference between the second embodiment and the first embodiment is that the welding positioning device also includes a nitrogen supply mechanism for providing nitrogen to the positioning seat 20 to prevent oxidation of the material during high-temperature welding and accelerate cooling after welding.

[0047] As an embodiment, the nitrogen supply mechanism includes a nitrogen delivery groove 51 arranged on the lower surface of the substrate 10 and a gas guide passage 52 that passes through the substrate 10 to introduce nitrogen in the nitrogen delivery groove 51 into the welding material hole 21 of the positioning seat 20.

[0048] Specifically, the nitrogen delivery groove 51 is fixedly arranged on the lower surface of the substrate, and the open end of the nitrogen delivery groove 51 is sealed and matched with the lower surface of the substrate 10 to form a nitrogen supply channel. In addition, according to the description of the first embodiment, when the stopper 40 is a screw in the first embodiment, the air guide passage 52 is a hollow passage axially passing through the screw; or, when the stopper 40 is other in the first embodiment, the air guide passage 52 can be opened on the lower part of the positioning seat 20 and the substrate below the positioning seat 20.

[0049] After nitrogen is introduced into the nitrogen delivery groove 51, it is supplied to the welding material hole 21 of the positioning seat 20 through the gas guide passage 52. In addition, when multiple positioning seats 20 are arranged on the substrate 10, the wiring of the nitrogen delivery groove 51 passes through the corresponding position of each positioning seat 20. After nitrogen is introduced into the nitrogen delivery groove 51, the nitrogen is dispersed into each positioning seat 20 through the gas guide passage 52 corresponding to each positioning seat 20.

[0050] Embodiment 3

[0051] Combination Figure 4 As shown, embodiment 3 provides a welding device, including the welding positioning device described in embodiment 1 or embodiment 2, and also including a driving device 60 and a high-temperature welding device 70. A plurality of positioning seats 20 are respectively arranged on a substrate 10 for relative rotation through bearings 30. The substrate 10 is arranged on the driving device 60. The substrate 10 is driven by the driving device 60 to move the plurality of positioning seats 20 one by one or in batches to the welding station of the high-temperature welding device 70.

[0052] As an embodiment, the driving device 60 includes a first frame 61 and a power source (not shown in the figure, such as a motor) arranged on the first frame 61, a transmission mechanism (not shown in the figure) and a turntable 62; the base plate 10 of the welding positioning device is an annular plate, and a plurality of positioning seats 20 are arranged on the base plate 10 in a circular distribution along the annular plate; the power source drives the turntable 62 to rotate through the transmission mechanism, and the base plate 10 is fixedly arranged on the outer periphery of the turntable.

[0053] As an alternative embodiment, the driving device 60 includes a first frame and a power source, a transmission mechanism (not shown in the figure) and a linear displacement module arranged on the first frame; the substrate 10 of the welding positioning device is a straight strip plate, and a plurality of positioning seats 20 are arranged on the substrate 10 in a straight line; the power source drives the linear displacement module to reciprocate through the transmission mechanism, and the substrate 10 is fixedly arranged on the linear displacement module.

[0054] Continue to see Figure 4 The high temperature welding device 70 includes a second frame 71 and a high temperature welding assembly 72 disposed on the second frame 71. The high temperature welding assembly 72 includes two induction coils disposed opposite to each other. The welding station of the high temperature welding device 70 is located between the two induction coils. When the substrate 10 is an annular plate, the welding station between the two induction coils is an arc channel; or when the substrate 10 is a straight strip plate, the welding station between the two induction coils is a straight channel.

[0055] When the two induction coils are powered on, they can heat the metal components between them at high temperatures. When the driving device 60 drives the substrate 10 to move, the plurality of positioning seats 20 and the materials to be welded thereon are moved one by one or in batches to the welding station of the high-temperature welding device 70; at this time, the high-temperature welding assembly 72 heats the welding parts and the solder ring between the first component and the second component to complete the welding.

[0056] Continue to see Figure 4 The welding equipment provided in the third embodiment also includes a friction member 80, which is fixedly arranged on the second frame 71. The friction member 80 has a friction actuating surface facing the positioning seat 20, and the friction actuating surface forms a friction fit with the outer periphery of the positioning seat 20 passing through the welding station, thereby driving the positioning seat 20 to rotate relative to the substrate 10 in the welding station, so that the high-temperature welding assembly 72 can heat the welding parts and solder rings of the first device and the second device in all directions, and the welding effect is better.

[0057] Among them, the friction actuating surface of the friction member 80 has the same direction as the welding station, that is, when the welding station is an arc channel, the friction actuating surface is an arc surface with the same arc as the arc channel; or, when the welding station is a straight channel, the friction actuating surface is a plane parallel to the straight channel.

[0058] In addition, as described in the first embodiment, the outer periphery of the positioning seat 20 is provided with an embossed pattern 26 for increasing the friction force; similarly, the friction actuating surface of the friction member 80 may also be provided with an embossed pattern for increasing the friction force.

[0059] Combination Figure 4 and Figure 5 As shown, based on the welding positioning device provided in the second embodiment, when the substrate 10 is an annular plate, a plurality of positioning seats 20 are arranged on the substrate 10 in an annular distribution along the annular plate; at this time, the nitrogen delivery groove 51 is also arranged on the lower surface of the substrate 1 in an annular shape. Similarly, when the substrate 10 is a straight strip plate, a plurality of positioning seats 20 are arranged on the substrate 10 in a straight line distribution; at this time, the nitrogen delivery groove 51 is also arranged on the lower surface of the substrate 10 in a straight line.
