Description

Technical Field

[0001] This utility model relates to the field of welding, and in particular to a welding device. Background Technology

[0002] Metal graphite spiral wound gaskets are static sealing elements for flange connections of valves, pumps, heat exchangers, towers, manholes, handholes, etc., and are widely used in petrochemical, machinery, power, metallurgy, shipbuilding, pharmaceutical, atomic energy and aerospace industries.

[0003] The manufacturing process includes a spot welding step, which requires a carrier to mount it. Existing carriers typically mount the device by abutting against its outer edge with a chamfer.

[0004] However, the above-mentioned technologies have at least the following technical problems:

[0005] The chamfering of metal-graphite spiral wound pads is generally formed by manual grinding. This results in significant variations in the shape and size of the chamfers on each pad, and even on the same pad, the chamfer shape varies at different locations. This can cause the carrier to jam when the workpiece rotates, severely impacting production efficiency and product consistency. Utility Model Content

[0006] The purpose of this invention is to provide a welding device to solve the problem of jamming that easily occurs in the carriers carrying metal graphite winding pads in the prior art.

[0007] The technical solution of this utility model is: a welding device, including a base assembly, on which a first support assembly and a second support assembly are provided; the first support assemblies are symmetrically arranged, and a pair of first support assemblies respectively have a first contact point and a second contact point that roll in contact with the chamfers on both sides of the annular workpiece;

[0008] The second support assembly has a third contact point capable of rolling contact with the annular workpiece, the projection of the center of gravity of the annular workpiece in the vertical direction being located in the plane formed by the first contact point, the second contact point, and the third contact point;

[0009] The first support component is connected to the base component via an adaptation mechanism, which includes an adaptation element made of an elastic material, allowing the relative positions of the first contact point and the second contact point to change.

[0010] Preferably, the first support assembly includes a first support wheel and a first wheel frame;

[0011] The adaptation mechanism includes a mounting base, which is hollow and has a cavity that can accommodate the first wheel frame. The adaptation element is disposed in the cavity, with one end of the adaptation element abutting against the first wheel frame and the other end abutting against the inner wall of the mounting base.

[0012] Preferably, the mounting base includes a frame, the frame has slots on both sides, a partition in the middle, and a baffle that is detachably connected to the frame, and the chamber is formed between the frame and the baffle;

[0013] The upper part of the first wheel frame is rotatably connected to the first support wheel, and the lower part has a step and is inserted into the cavity. The mounting base is provided with a cover plate that is detachably connected to the frame and can abut against the step.

[0014] Preferably, the adaptor is made of silicone material.

[0015] Preferably, the base assembly includes a first base and a second base, the first base being a pair corresponding to the first support assembly and the second support assembly; the second base is provided with a lifting mechanism, and the end of the first base away from the first support assembly or the second support assembly is connected to the lifting mechanism.

[0016] Preferably, the lifting mechanism includes a guide rail fixed on a second base and a lifting driver arranged parallel to the guide rail. The first base is slidably disposed on the guide rail and fixed to the execution end of the lifting driver. The lifting driver drives the first base to move along the length direction of the guide rail.

[0017] Preferably, the lifting driver is connected to the second base via an adjustment mechanism, the adjustment mechanism including an adjustment hole, an adjustment base plate, and an adjustment pin;

[0018] The adjustment holes are arranged in multiple ways parallel to the guide rail on the second base. The adjustment base plate is set perpendicular to the second base. The adjustment pin passes through the adjustment base plate and is inserted into the adjustment hole. The lifting driver is set through the adjustment base plate.

[0019] Compared with the prior art, the advantages of this utility model are:

[0020] (1) The first support component is connected to the base through an adaptor made of silicone material, allowing the relative position of the first contact point and the second contact point to be dynamically adjusted. When the chamfer size changes, the first support wheel can compress the silicone part to move in the vertical direction, adaptively matching the chamfer differences of different workpieces or different positions of the same workpiece, thus solving the jamming problem.

[0021] (2) The mounting base adopts a frame, detachable baffle and cover design, which facilitates quick disassembly and assembly of the first wheel frame and replacement of silicone adapter parts, reducing maintenance costs.

[0022] (3) The adjustment mechanism, through the cooperation of the adjustment pin and multiple sets of adjustment holes, can flexibly adjust the height of the lifting drive, adapt to workpieces of different diameters, and significantly expand the applicable range of the equipment.

[0029] The present invention will be further described in detail below with reference to specific embodiments:

[0030] like Figure 1 and Figure 2 As shown, a welding device is provided for mounting a ring-shaped workpiece (metal-graphite spiral wound gasket) during the welding process in its fabrication. It includes a base assembly 3, on which a first support assembly 1 and a second support assembly 2 are mounted.

[0031] The metal-graphite wound gasket is driven by an external device to rotate around its own axis. The first support components 1 are symmetrically arranged, each pair having a first contact point and a second contact point that rolls into contact with the chamfered sides of the annular workpiece. The second support component 2 includes a second support wheel 21, which has a third contact point capable of rolling into contact with the annular workpiece. The projection of the center of gravity of the annular workpiece in the vertical direction lies within the plane formed by the first, second, and third contact points. This achieves the mounting of the annular workpiece.

[0032] During the manufacturing process of metal-graphite spiral wound gaskets, the chamfers on both sides are often made by hand, resulting in significant differences in the shape and size of the chamfers for each gasket. Furthermore, the chamfer shapes at different locations on the same metal-graphite spiral wound gasket are also different. The fixed first and second contact points can easily cause the metal-graphite spiral wound gasket to jam during rotation.

[0033] To solve this problem, the first support component 1 is connected to the base component 3 through an adaptation mechanism 4. The adaptation mechanism 4 includes an adaptation element 43 made of an elastic material, which allows the relative positions of the first contact point and the second contact point to change.

[0034] Specifically, in combination Figure 3 and Figure 4 As shown, the first support assembly 1 includes a first support wheel 11 and a first wheel frame 12. The adaptation mechanism 4 is assembled from multiple components, including a mounting base 41. The mounting base 41 is hollow and has a cavity 42 that can accommodate the first wheel frame 12. An adaptation member 43 is disposed in the cavity 42, with one end of the adaptation member 43 abutting against the first wheel frame 12 and the other end abutting against the inner wall of the mounting base 41. The mounting base 41 includes a frame 411 with slots on both sides and a partition 412 formed in the middle. A baffle 413 is provided that is detachably connected to the frame 411. The cavity 42 is formed between the frame 411 and the baffle 413. The upper part of the first wheel frame 12 is rotatably connected to the first support wheel 11, and the lower part has a step 121 that is inserted into the cavity 42. The mounting base 41 is provided with a cover plate 414 that is detachably connected to the frame 411 and can abut against the step 121. In this embodiment, the adaptation member 43 is made of silicone material.

[0035] The first support wheel 11, together with the first wheel frame 12, can move vertically by compressing the adaptor 43 made of silicone material, thereby changing the distance between the first contact point and the second contact point, thus adapting to different workpieces or changes in the chamfer size at different positions on the same workpiece.

[0036] like Figure 1 As shown, this device also has a lifting mechanism 5, which is used to disengage the first support assembly 1 and the second support assembly 2 from the workpiece during loading and unloading.

[0037] Specifically, the base assembly 3 includes a first base 31 and a second base 32. The first base 31 is set as a pair with the first support assembly 1 and the second support assembly 2. The second base 32 is provided with a lifting mechanism 5. The end of the first base 31 away from the first support assembly 1 or the second support assembly 2 is connected to the lifting mechanism 5.

[0038] The lifting mechanism 5 includes a guide rail 51 fixed on the second base 32 and a lifting driver 52 arranged parallel to the guide rail 51. The first base 31 is slidably arranged on the guide rail 51 and fixed to the execution end of the lifting driver 52. The lifting driver 52 drives the first base 31 to move along the length direction of the guide rail 51.

[0039] Furthermore, an adjustment mechanism 6 is also provided. The lifting driver 52 is connected to the second base 32 through the adjustment mechanism 6. The adjustment mechanism 6 is used to adjust the height of the lifting driver 52, thereby enabling the first support assembly 1 and the second support assembly 2 to mount ring-shaped workpieces of different diameters.

[0040] Specifically, the adjustment mechanism 6 includes adjustment holes 61, an adjustment base plate 62, and adjustment pins 63. Multiple adjustment holes 61 are arranged parallel to the guide rail 51 on the second base 32. The adjustment base plate 62 is perpendicular to the second base 32. The adjustment pins 63 penetrate the adjustment base plate 62 and are inserted into the adjustment holes 61. The lifting driver 52 is disposed on the adjustment base plate 62. By inserting the adjustment pins 63 into different adjustment holes 61, the initial positions of the adjustment base plate 62 and the lifting driver 52 can be adjusted, thereby lifting the corresponding first support assembly 1 or second support assembly 2 to different heights, thus accommodating ring-shaped workpieces of different diameters.

They should not be construed as limiting the scope of protection of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
