Description

Technical Field

[0001] This utility model relates to the field of smelting technology, specifically to a fixing device for welding consumable electrodes. Background Technology

[0002] In the preparation of titanium and titanium alloy ingots by vacuum consumable arc melting (CAW), a consumable electrode composed of electrode blocks is fixed by a material rack so that a plasma welding box or electron beam welding box can weld the consumable electrode, and then the consumable electrode is subjected to vacuum CAW to complete the preparation of titanium and titanium alloy ingots. However, when the length of the consumable electrode is less than the fixed length of the material rack, the material rack cannot effectively fix the consumable electrode due to insufficient clamping range, which seriously affects the welding efficiency of the consumable electrode. Existing technologies adjust the material rack structure or replace the fitting fixture to accommodate the length of the consumable electrode, but these methods are complicated to operate, costly, and lack versatility.

[0006] The support assembly includes an inner support column and an outer support column. The first end of the inner support column is slidably inserted into the first end of the outer support column. The second end of the inner support column is connected to the first fixing plate, and the second end of the outer support column is connected to the second fixing plate. The inner support column has a plurality of first limiting holes evenly distributed on its side, and the outer support column has a plurality of second limiting holes evenly distributed on its side. The first limiting holes and the second limiting holes correspond one-to-one, so that a first limiting pin can be simultaneously inserted into the first limiting hole and the corresponding second limiting hole to adjust the predetermined distance.

[0007] According to the fixing device for welding consumable electrodes provided in the embodiment of this utility model, the distance between adjacent first limiting holes and the distance between adjacent second limiting holes are both 50-100mm.

[0008] The fixing device for consumable electrode welding provided according to the embodiments of this utility model further includes:

[0009] The base has a supporting outer column connected to the ground-facing side via a connecting assembly. The connecting assembly includes an inner connecting column and an outer connecting column. The first end of the inner connecting column is slidably inserted into the first end of the outer connecting column, and the second end of the inner connecting column is connected to the ground-facing side of the supporting outer column. The second end of the outer connecting column is connected to the base. The inner connecting column has multiple third limiting holes evenly spaced on its side, and the outer connecting column has multiple fourth limiting holes evenly spaced on its side. The third and fourth limiting holes correspond one-to-one, allowing a second limiting pin to be simultaneously inserted into both the third and corresponding fourth limiting holes to adjust the height of the first and second fixing plates from the ground.

[0010] According to the fixing device for welding consumable electrodes provided in the embodiment of this utility model, the distance between adjacent third limiting holes and the distance between adjacent fourth limiting holes are both 200-400mm.

[0011] According to the fixing device for welding consumable electrodes provided in the embodiment of the present utility model, a rubber layer is provided on the side of the first fixing plate and the second fixing plate that abuts against the end face of the consumable electrode, and the rubber layer is fixed to the first fixing plate and the second fixing plate by adhesive or snap-fit.

[0012] According to the fixing device for welding consumable electrodes provided in the embodiments of this utility model, the thickness of the rubber layer is 3-5mm.

[0013] According to the fixing device for welding consumable electrodes provided in the embodiment of this utility model, the extension ratio of the support component is 1:2.

[0014] According to the fixing device for welding consumable electrodes provided in the embodiments of this utility model, both the first fixing plate and the second fixing plate are titanium alloy plates.

[0015] According to the fixing device for welding consumable electrodes provided in the embodiment of this utility model, a lifting lug is provided on the side of the supporting outer column away from the ground.

[0016] The fixing device for consumable electrode welding provided according to the embodiments of this utility model further includes:

[0017] The first rib plate is connected to both the inner support column and the first fixing plate.

[0018] The second rib plate is connected to both the supporting outer column and the second fixing plate.

[0019] The advantages and beneficial effects of this utility model are as follows:

[0020] The fixing device for welding consumable electrodes provided in this application allows the inner support column to slide inside the outer support column during welding of a consumable electrode composed of electrode blocks, thereby adjusting a predetermined distance between the first and second fixing plates. When the predetermined distance is equal to the difference between the fixed length between the two fixing surfaces of the material rack and the length of the consumable electrode, a first limiting pin is simultaneously inserted into the first limiting hole and the corresponding second limiting hole, thus fixing the inner support column inside the outer support column. Since the fixing device can compensate for the length difference between the material rack and the consumable electrode, one of the first and second fixing plates abuts against the end face of the consumable electrode, and the other abuts against the fixing surface of the material rack. This, combined with existing material racks, enables the fixing of the consumable electrode. By adjusting the length of the fixing device to fit the material rack, it allows for the fixing of consumable electrodes of different sizes, improving welding efficiency. The device is simple to operate, low in cost, and highly versatile. Attached Figure Description

[0030] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0031] Figure 1 This is a three-dimensional structural schematic diagram of the fixing device 30 for welding consumable electrodes in an embodiment of this utility model. Figure 2 This is a schematic diagram of the fixing device 30 for consumable electrode welding in the working state in an embodiment of this utility model. Figure 3 This is a top view of the fixing device 30 for welding consumable electrodes in an embodiment of this utility model. Figure 4 yes Figure 3 A schematic diagram of the cross-sectional structure along section line AA, as shown below. Figures 1 to 4 As shown, this application provides a fixing device 30 for consumable electrode welding, comprising:

[0032] The first fixing plate 1 and the second fixing plate 2 are connected by the support assembly 3; one of the first fixing plate 1 and the second fixing plate 2 abuts against the end face of the self-consumable electrode 20, and the other of the first fixing plate 1 and the second fixing plate 2 abuts against the fixing surface of the material rack 10; the first fixing plate 1 and the second fixing plate 2 are arranged in parallel, and there is a predetermined distance between the first fixing plate 1 and the second fixing plate 2.

[0033] The support assembly 3 includes an inner support column 31 and an outer support column 32. The first end of the inner support column 31 is slidably inserted into the first end of the outer support column 32. The second end of the inner support column 31 is connected to the first fixing plate 1, and the second end of the outer support column 32 is connected to the second fixing plate 2. The inner support column 31 has a plurality of first limiting holes 33 evenly distributed on its side, and the outer support column 32 has a plurality of second limiting holes 34 evenly distributed on its side. The first limiting holes 33 and the second limiting holes 34 correspond one-to-one so that the first limiting pin 35 can be simultaneously inserted into the first limiting hole 33 and the corresponding second limiting hole 34 to adjust the predetermined distance.

[0034] The fixing device 30 provided in this application for welding consumable electrodes allows the inner support column 31 to slide inside the outer support column 32 when welding a consumable electrode 20 composed of electrode blocks, thereby adjusting a predetermined distance between the first fixing plate 1 and the second fixing plate 2. When the predetermined distance is equal to the difference between the fixed length between the two fixing surfaces of the material rack 10 and the length of the consumable electrode 20, the first limiting pin 35 is simultaneously inserted into the first limiting hole 33 and the corresponding second limiting hole 34, thus fixing the inner support column 31 inside the outer support column 32. Since the fixing device 30 can compensate for the length difference between the material rack 10 and the consumable electrode 20, one of the first fixing plate 1 and the second fixing plate 2 abuts against the end face of the consumable electrode 20, and the other of the first fixing plate 1 and the second fixing plate 2 abuts against the fixing surface of the material rack 10, thus enabling the fixing of the consumable electrode 20 in conjunction with the existing material rack 10. By adjusting the length of the fixing device 30 to fit the material rack 10, consumable electrodes 20 of different sizes can be fixed, thereby improving the welding efficiency of consumable electrodes. The operation is simple, the cost is low, and the versatility is good.

[0035] In some embodiments, the spacing between adjacent first limiting holes 33 and adjacent second limiting holes 34 is 50-100mm. On one hand, this 50-100mm spacing ensures the adjustment accuracy of the fixing device 30, thereby improving its applicability to consumable electrodes 20 of different sizes. On the other hand, it avoids excessively dense hole spacing in the support component 3, which could reduce the structural strength of the support component 3 and affect the supporting force of the fixing component. Both the first limiting holes 33 and the second limiting holes 34 are laser-drilled to ensure hole alignment accuracy ≤0.5mm, preventing jamming when the first limiting pin 35 is inserted.

[0036] In some embodiments, the inner support column 31 has first limiting holes 33 on both opposite sides, and the outer support column 32 has second limiting holes 34 on both opposite sides. Two first limiting pins 35 are inserted into the corresponding first limiting holes 33 and second limiting holes 34, respectively, meaning that both symmetrical sides of the support assembly 3 are simultaneously fixed by the first limiting pins 35, thereby improving the force balance of the support assembly 3. Alternatively, a single first limiting pin 35 can be used, passing through both first limiting holes 33 and both second limiting holes 34 simultaneously, to simplify the structure of the support assembly 3.

[0037] Figure 5 This is a front view schematic diagram of the fixing device 30 used for consumable electrode welding in an embodiment of this utility model. Figure 6 yes Figure 5 A schematic diagram of the cross-sectional structure along section line BB, as shown below. Figure 5 and Figure 6As shown, the fixing device 30 also includes a base 5. The side of the outer support column 32 facing the ground is connected to the base 5 via a connecting assembly 4; the connecting assembly 4 includes a connecting inner column 41 and a connecting outer column 42, the first end of the connecting inner column 41 is slidably inserted into the first end of the connecting outer column 42, and the second end of the connecting inner column 41 is connected to the side of the outer support column 32 facing the ground; the second end of the connecting outer column 42 is connected to the base 5; a plurality of third limiting holes 43 are evenly distributed on the side of the connecting inner column 41, and a plurality of fourth limiting holes 44 are evenly distributed on the side of the connecting outer column 42, the third limiting holes 43 and the fourth limiting holes 44 correspond one-to-one, so that the second limiting pin 45 can be simultaneously inserted into the third limiting hole 43 and the corresponding fourth limiting hole 44 to adjust the height of the first fixing plate 1 and the second fixing plate 2 from the ground.

[0038] When the existing material rack 10 has different heights, the height of the consumable electrode 20 also changes. By setting the connecting component 4 and the base 5, on the one hand, the base 5 can support and fix the support component 3, the first fixing plate 1 and the second fixing plate 2 so that the consumable electrode 20 can be quickly aligned with the fixing component. On the other hand, the connecting component 4 can adjust the height of the support component 3, the first fixing plate 1 and the second fixing plate 2 from the ground to accommodate consumable electrodes 20 at different heights from the ground.

[0039] In some embodiments, the spacing between adjacent third limiting holes 43 and adjacent fourth limiting holes 44 is 200-400mm. On one hand, this 200-400mm spacing ensures the adjustment accuracy of the fixing device 30, thereby improving its applicability to consumable electrodes 20 of different heights. On the other hand, it prevents the holes in the connecting component 4 from being too dense, which could reduce the structural strength of the connecting component 4 and affect its supporting force. Both the third limiting holes 43 and the fourth limiting holes 44 are laser-drilled to ensure an alignment accuracy of ≤0.5mm, preventing jamming when the second limiting pin 45 is inserted.

[0040] In some embodiments, the two opposite sides of the connecting inner column 41 are provided with third limiting holes 43, and the two opposite sides of the connecting outer column 42 are provided with fourth limiting holes 44. Two second limiting pins 45 are respectively inserted into the corresponding third limiting holes 43 and fourth limiting holes 44, meaning that the symmetrical sides of the connecting assembly 4 are simultaneously fixed by the second limiting pins 45, thereby improving the force balance of the connecting assembly 4. Alternatively, a single second limiting pin 45 can be provided, which simultaneously passes through both third limiting holes 43 and both fourth limiting holes 44, to simplify the structure of the connecting assembly 4.

[0041] Figure 7 This is a side view of the fixing device 30 for welding consumable electrodes in an embodiment of this utility model. Figure 8 yes Figure 7A schematic diagram of the cross-sectional structure along section line CC, as shown below. Figure 7 and Figure 8 As shown, a rubber layer 11 is provided on the side of the first fixing plate 1 and the second fixing plate 2 that abuts against the end face of the consumable electrode 20. The rubber layer 11 is fixed to the first fixing plate 1 and the second fixing plate 2 by adhesive bonding or snap-fit. The rubber layer 11 prevents the first fixing plate 1 and the second fixing plate 2 from scratching or damaging the end face of the consumable electrode 20, or from causing surface contamination of the consumable electrode 20. The rubber layer 11 can undergo elastic deformation to compensate for dimensional errors of the consumable electrode 20 and improve the clamping stability of the fixing device 30. Because the rubber layer 11 is bonded or snap-fitted to the first fixing plate 1 and the second fixing plate 2, it is convenient to replace the worn rubber layer 11 in a timely manner.

[0042] In some embodiments, the thickness of the rubber layer 11 is 3-5 mm. Anti-slip textures can be provided on the surface of the rubber layer 11 that contacts the consumable electrode 20 to increase the friction between the rubber layer 11 and the consumable electrode 20 and improve the clamping stability of the fixing device 30.

[0043] In some embodiments, the extension ratio of the support component 3 is 1:2. Specifically, when the fixing device 30 is in the retracted state, the predetermined distance between the first fixing plate 1 and the second fixing plate 2 can be 500mm. When the fixing device 30 is in the extended state, the predetermined distance between the first fixing plate 1 and the second fixing plate 2 can be 1000mm. Because the length is reduced by 50% after retraction, the space occupied is reduced. The contact surfaces between the inner support column 31 and the outer support column 32 are chrome-plated to increase surface wear resistance and corrosion resistance.

[0044] In some embodiments, both the first fixing plate 1 and the second fixing plate 2 are titanium alloy plates. On one hand, titanium alloy plates are lighter than steel, reducing the weight of the fixing device 30 and facilitating its transfer and handling. On the other hand, both the titanium alloy plates and the consumable electrode 20 are made of titanium, preventing contamination of the consumable electrode 20. The titanium alloy plates are 8-10 mm thick and are circular with rounded edges to prevent scratches to operators.

[0045] In some embodiments, a lifting lug 6 is provided on the side of the outer support column 32 that is away from the ground, so as to facilitate the transfer and transportation of the fixing device 30.

[0046] In some embodiments, the fixing device 30 further includes a first rib 7 and a second rib 8. The first rib 7 is connected to both the inner supporting column 31 and the first fixing plate 1, and the second rib 8 is connected to both the outer supporting column 32 and the second fixing plate 2. By providing the first rib 7 and the second rib 8, the connection strength between the inner supporting column 31 and the first fixing plate 1, as well as the connection strength between the outer supporting column 32 and the second fixing plate 2, is enhanced. Both the first rib 7 and the second rib 8 adopt a triangular reinforcing rib structure and are welded to the included angle between the inner supporting column 31 and the first fixing plate 1, and the included angle between the outer supporting column 32 and the second fixing plate 2.

[0047] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
