Description

Technical Field

[0001] This invention relates to the field of weld technology, and in particular to the fixtures, applications and welding methods for ceramic spacers in butt welds. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] On components of some mechanical equipment, such as excavators, butt welds typically require the addition of steel molten pool plates and ceramic backing blocks at the ends to extend the weld's initiation and termination points beyond the base material, ensuring weld quality at both ends. The commonly used method is as follows: 1. Embed the steel molten pool plate into the bottom of the weld and weld it in place. Insert the perforated ceramic pad into the steel molten pool plate and weld the ends of the steel molten pool plate to prevent the ceramic pad from falling off when the component is flipped. 2. After the weld is completed, the ceramic pad is broken and removed, and the steel molten pool plate is gouged out before subsequent grinding operations.

[0004] The inventors discovered that the welding method described above has the following shortcomings: 1) Fixing the ceramic pads requires welding and melting operations, which increases labor and material costs; 2) The ceramic pads after welding need to be broken to be removed, which cannot be reused, resulting in waste; at the same time, the breaking work also increases the workload and labor costs. 3) Fixing and removing ceramic pads takes a long time, which affects processing efficiency. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a fixing tool for ceramic spacers in butt welds, which facilitates the fixing and removal of ceramic spacers and enables the reuse of ceramic spacers.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: A fixing fixture for ceramic pads in butt welds includes a first bracket and a second bracket. The first bracket and the second bracket are opposite to each other and movably connected. The first bracket and the second bracket are respectively positioned on opposite sides of the weld. A retaining seat is provided on one side of the first bracket and the second bracket to engage with the ceramic pad on the corresponding side. The first bracket and the second bracket are bent to allow them to be mounted on the side of the weld. One of the first bracket and the second bracket is movable relative to the other. Fasteners can secure the first bracket and the second bracket.

[0007] As described above, after the first bracket engages with the ceramic pad on one side, the second bracket can be moved relative to the first bracket to engage with the ceramic pad on the corresponding side. After engagement, both the first and second brackets are bent, allowing the first and second brackets to be mounted on the weld side of the component. Fasteners fix the first and second brackets, ensuring stable support of the ceramic pads on both sides by the entire fixture, eliminating the need for welding or melting the ceramic pads.

[0008] As described above, a fixing fixture for ceramic pads for butt welds is provided, wherein the first bracket and the second bracket are slidably connected. The first bracket has a protrusion at one end and a groove on the protrusion. One end of the second bracket passes through the groove of the protrusion and is movable relative to the groove. The insertion of one end of the second bracket into the groove helps to maintain the integrity of the first and second brackets and facilitates the movement of the second bracket relative to the first bracket, thereby improving the installation efficiency of the fixing fixture.

[0009] As described above, a fixing fixture for ceramic pads in butt welds has a limiting member at one end of the second bracket near the first bracket. The limiting member is used to limit the movement of the second bracket. The height of the limiting member is greater than the height of the slide groove, and / or the width of the limiting member is greater than the width of the slide groove.

[0010] As described above, a fixing fixture for a ceramic pad for butt welds includes a U-shaped base and a U-shaped side seat. The two ends of the U-shaped side seat are respectively connected to the two ends of the U-shaped base. The U-shaped base engages with the ceramic pad from the bottom side, and the U-shaped side seat engages with the ceramic pad from the outside side. The U-shaped side seat can be placed below the molten pool plate extending from the ceramic pad. The inner widths of the U-shaped base and the U-shaped side seat are respectively adapted to the first dimension of the ceramic pad. The first dimension of the ceramic pad is set along the width direction of the weld, thereby ensuring the engagement of the U-shaped base, the U-shaped side seat and the ceramic pad. The height of the inner side of the U-shaped base is less than or equal to the distance between the lower surface of the molten pool plate and the bottom surface of the ceramic pad.

[0011] As described above, a fixing fixture for ceramic pads in butt welds includes a first bracket comprising a first section, a second section, and a third section connected in sequence. The first section is L-shaped, the second section is provided with the aforementioned bracket, and the second section is positioned along the width direction of the weld. The third section is also L-shaped. The first and third sections are respectively placed on opposite sides of the length direction of the weld. The spacing between the first and third sections ensures that there is no obstruction within a set range on both sides of the weld, thus preventing interference between the fixing fixture and the welding torch during welding.

[0012] As described above, in a fixing fixture for ceramic pads for butt welds, the structure of the second bracket is similar to that of the first bracket, and the end of the second bracket near the first bracket is slidably connected to the end of the first bracket near the second bracket.

[0013] As described above, in a fixing fixture for ceramic pads for butt welds, considering the movement of the second bracket relative to the first bracket, the length of the longer side of the first segment and the third segment is greater than 1 / 2 of the weld length; The length of the shorter side of the first segment and the third segment is greater than the minimum distance between the lower surface of the molten pool plate and the upper surface of the component, and less than or equal to the thickness of the ceramic pad; The second segment includes straight segments located on both sides of the U-shaped base. The straight segments are connected to the middle of the side of the U-shaped base. The straight segments are located in the middle of the side of the U-shaped base, which facilitates the stable support of the base by the straight segments.

[0014] As described above, a fixing fixture for a ceramic pad for butt welds is provided, wherein the fastener is a fastening bolt, which passes through one side of the protrusion and abuts against the second bracket; Alternatively, the fastening bolt passes through the protrusion, the second bracket, and is connected to the nut.

[0015] Secondly, the present invention also provides an application of a fixing fixture for ceramic spacers in butt welds, which is applied to the welding of butt welds in excavators.

[0016] Thirdly, the present invention also provides a welding method for butt welds, employing the aforementioned fixing fixture for ceramic spacers in butt welds, comprising the following: Embed and fix the molten pool plate at the bottom of the weld, and insert the perforated ceramic pad into the molten pool plate; Loosen the fasteners and engage the bracket at the first bracket with the ceramic pad on one side. Move the second bracket relative to the first bracket so that the bracket at the second bracket engages with the ceramic pad on the other side, thereby enabling the first bracket and the second bracket to be mounted on the component at the weld side. Fasteners secure the first bracket and the second bracket together, making the first bracket and the second bracket a single structural component. Weld the weld seam; After the weld is completed, loosen the fasteners, remove the first and second brackets, and then remove the ceramic pad relative to the molten pool plate.

[0017] The beneficial effects of the present invention are as follows: 1) The present invention achieves engagement between the second bracket and the ceramic pad on the corresponding side by moving the second bracket relative to the first bracket after the first bracket engages with the ceramic pad on one side. After engagement, the first bracket and the second bracket are fixed by fasteners, ensuring stable support of the ceramic pads on both sides by the entire fixing fixture. There is no need to weld and melt the ceramic pads, reducing the labor and material costs associated with welding.

[0018] 2) The structure of the fixing fixture in this invention is reasonable. After welding, there is no need to break the ceramic pad. The fixing fixture can be removed by moving the first bracket and the second bracket, which facilitates the disassembly of the ceramic pad and makes the ceramic pad reusable, thus avoiding waste. Moreover, the overall process greatly facilitates the fixing and disassembly of the ceramic pad, which is conducive to improving processing efficiency.

[0019] 3) In this invention, both the first bracket and the second bracket are bent, which not only facilitates the engagement of the card seat with the corresponding ceramic pad, but also facilitates the components on the weld side of the first bracket and the second bracket, and correspondingly facilitates the movement of the second bracket relative to the first bracket.

[0020] 4) The card holder structure in this invention is reasonably designed. The U-shaped base and the U-shaped side seat cooperate, one of which engages with the ceramic pad from the bottom side of the ceramic pad, and the other engages with it from the outside side of the ceramic pad. The ceramic pad is fixed from two directions, so that the ceramic pad fits tightly with the side of the component, ensuring that the ceramic pad can be stably fixed without welding. In addition, the U-shaped side seat can be placed below the molten pool plate to avoid interference with the molten pool plate.

[0021] 5) In this invention, the first bracket and the second bracket have the same structure, only the ends are different. The difference in the ends can ensure the movement of the second bracket relative to the first bracket, or the movement of the first bracket relative to the second bracket. Since the first bracket and the second bracket have basically the same structure, the positions of the first bracket and the second bracket can be interchanged, which is beneficial to the quick engagement of the fixing fixture and the ceramic pad.

[0027] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, unless otherwise expressly indicated by the invention, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof. As described in the background section, the fixing and removal of ceramic pads in the prior art is time-consuming and labor-intensive. In order to solve the above technical problems, the present invention proposes a fixing fixture for ceramic pads in butt welds.

[0029] Example 1 In a typical embodiment of the present invention, reference is made to Figure 1 and Figure 2 As shown, a fixing fixture for ceramic pads in butt welds includes a first bracket 1 and a second bracket 2. The first bracket 1 and the second bracket 2 are arranged opposite each other. The first bracket 1 and the second bracket 2 can be placed on both sides of the weld 5 respectively. A retaining seat 4 is provided on one side of the first bracket 1 and the second bracket 2 to engage with the ceramic pad 7 on the corresponding side. The first bracket 1 and the second bracket 2 are bent so that the first bracket 1 and the second bracket 2 can be mounted on the component 6 on the side of the weld. One of the first bracket 1 and the second bracket 2 is movable relative to the other. Fasteners 3 can fasten the first bracket 1 and the second bracket 2.

[0030] The first bracket 1 includes a first section 1-1, a second section 1-2, and a third section 1-3 connected in sequence. The first section 1-1 is L-shaped, and the second section is equipped with a retainer 4. The second section 1-2 is set along the width direction of the weld. The third section 1-3 is also L-shaped. The second section is placed on the outside of the weld between the components so that the retainer of the second section can be engaged with the ceramic pad from the outside and bottom. The first section 1-1 and the third section 1-3 are respectively placed on opposite sides of the length direction of the weld 5. The interval between the first section and the third section is set so that there is no obstruction within the set range on both sides of the weld, and interference between the fixing fixture and the welding gun is avoided during welding. It should be explained that the structure of the second bracket 2 is similar to that of the first bracket 1. The second bracket 2 also includes a first section, a second section, and a third section connected in sequence. The structure of the second section is the same as that of the second section of the first bracket. The similarity between the first and second brackets facilitates their interchangeability, and their positions do not need to be considered when fixing them. The difference between the two is that the arrangement of the first and third sections of the first bracket away from the second section is different from the structure of the first and third sections of the second bracket away from the second section, in order to ensure the connection between the first and second brackets.

[0031] It is easy to understand that as long as the ceramic pads 7 on both sides of the weld 5 are the same, the structure and size of the corresponding brackets on both sides are the same, that is, the size of the brackets 4 on the corresponding side of the first bracket and the second bracket is compatible with the size of the ceramic pads on the corresponding side.

[0032] Specifically, the first segment 1-1 and the third segment 1-3 are L-shaped connecting rods. When in use, the longer side of the first segment and the third segment is placed above the upper surface of the component 6, so that it does not come into contact with the surface of the component 6. The shorter side of the first segment is placed on the side of the component, and the shorter side of the first segment and the third segment is spaced apart from the side of the component. The cross-section of the first segment and the third segment is square, which is conducive to the manufacturing of the fixed tooling.

[0033] In this embodiment, the card holder 4 includes a U-shaped base 4-1 and a U-shaped side seat 4-2. The two ends of the U-shaped side seat 4-2 are respectively connected to the two ends of the U-shaped base 4-1. The U-shaped side seat 4-2 is perpendicularly connected to the vertical section of the U-shaped base 4-1. The U-shaped base 4-1 engages with the ceramic pad 7 from the bottom side of the ceramic pad. The U-shaped side seat 4-2 engages with the ceramic pad 7 from the outside side of the ceramic pad. The U-shaped side seat can be placed below the molten pool plate extending from the ceramic pad. The inner width of the U-shaped base 4-1 is the same as the inner width of the U-shaped side seat 4-2. The inner width of the U-shaped base 4-1 and the inner width of the U-shaped side seat 4-2 are respectively adapted to the first dimension of the ceramic pad 7. The first dimension refers to the length or width of the ceramic pad 7. The first dimension is the dimension of the ceramic pad 7 along the width direction of the weld 5, thereby ensuring the engagement of the U-shaped base 4-1, the U-shaped side seat 4-2 and the ceramic pad.

[0034] In addition, the second section of the first bracket 1 and the second bracket 2 includes straight sections located on both sides of the U-shaped base 4-1. The straight sections are located on the same plane as the shorter side of the first section 1-1 and the third section 1-3. The straight sections are located on the same plane as the U-shaped base. Specifically, the straight sections are straight rods. The straight sections are connected to the middle of the side of the U-shaped base. The straight sections are located in the middle of the side of the U-shaped base, which is conducive to the stable support of the base by the straight sections.

[0035] In this embodiment, the movement of the second bracket 2 relative to the first bracket 1 is based on the structural design, and the length of the longer side of the first and third segments is greater than 1 / 2 of the weld length. In addition, the length of the shorter side of the first segment 1-1 and the third segment 1-3 (that is, the height of the first segment or the third segment) is greater than the minimum distance between the lower surface of the molten pool plate 8 and the upper surface of the component 6. This allows the U-shaped side seat of the card holder 4 to be placed below the molten pool plate 8. At the same time, it can also ensure that after the card holder is engaged with the ceramic pad, the longer side of the first segment and the third segment can be placed above the component 6. The length of the shorter side of the first segment and the third segment is less than or equal to the thickness of the ceramic pad 7, which can prevent the first segment and the third segment from being too high and ensure the welding of the weld seam 5 by the welding torch. Furthermore, in this embodiment, the U-shaped side seat 4-2 can contact the molten pool plate / lower surface that passes through the ceramic pad 7. Therefore, the height of the inner side of the U-shaped base 4-1 is less than or equal to the distance between the lower surface of the molten pool plate 8 and the bottom surface of the ceramic pad 7.

[0036] It should be noted that the first bracket 1 and the second bracket 2 are slidably connected; in this embodiment, the end of the second bracket 2 near the first bracket is slidably connected to the end of the first bracket near the second bracket. In this embodiment, protrusions 1-4 are provided on the inner sides of the first and third sections of the first bracket. The protrusions 1-4 are provided with sliding grooves. The height of the protrusions 1-4 is greater than the height of the first section 1-1, and the width of the protrusions 1-4 is greater than the width of the first section 1-1. The sliding grooves are adapted to the dimensions of the first or third section of the second bracket. One end of the second bracket passes through the sliding groove of the protrusion. The second bracket is movable relative to the sliding groove. One end of the second bracket 2 is inserted into the sliding groove, which helps to maintain the integrity of the first bracket 1 and the second bracket 2, and also facilitates the movement of the second bracket relative to the first bracket, thereby improving the installation efficiency of the fixing fixture.

[0037] A limiting member 2-1 is provided at one end of the second bracket 2 near the first bracket 1. The limiting member 2-1 can be a limiting block. The limiting member 2-1 is used to limit the movement of the second bracket and prevent the end of the second bracket from coming out of the slide groove. The height of the limiting member 2-1 is greater than the height of the slide groove. Of course, in other examples, the width of the limiting member 2-1 can be greater than the width of the slide groove.

[0038] In this embodiment, the fastener 3 is a fastening bolt, and the protrusion 1-4 is provided with a threaded hole. The fastening bolt passes through one side of the protrusion 1-4 and abuts against the second bracket 2. In other examples, the protrusion has a through hole or a threaded hole, the second bracket has a through hole or a threaded hole, and the fastening bolt is connected to the nut after passing through the through hole or threaded hole of the protrusion or the second bracket.

[0039] The fixing fixture provided in this embodiment, after the first bracket 1 engages with the ceramic pad 7 on one side, moves the second bracket 2 relative to the first bracket 1 to engage with the corresponding ceramic pad 7. After engagement, both the first and second brackets are bent, allowing the first and second brackets to be mounted on the weld side of the component. Fasteners fix the first and second brackets, ensuring stable support of the ceramic pads on both sides of the fixing fixture without the need for welding or melting the ceramic pads. Moreover, by loosening the fasteners and moving the second and first brackets, the fixing fixture can be dismantled, thus facilitating the removal of the ceramic pads without breaking them, and enabling the reuse of the ceramic pads.

[0040] Example 2 The difference between this embodiment and Embodiment 1 is that: The first bracket is movable relative to the second bracket. A protrusion is provided on one side of the second bracket, and a groove is provided on the protrusion. The end of the first bracket can pass through the groove. That is, the structure of the second bracket in this embodiment is similar to the structure of the first bracket in embodiment one, and the structure of the first bracket is the same as the structure of the second bracket in embodiment one.

[0041] Example 3 The difference between this embodiment and Embodiment 1 is that: the first bracket is hollow at one end near the second bracket, one end of the second bracket is inserted into the hollow end of the first bracket, and multiple threaded holes are provided in the hollow end of the first bracket, and one or more fasteners can pass through one or more of the different threaded holes and abut against the end of the second bracket.

[0042] Example 4 This embodiment provides an application of a ceramic spacer fixing fixture for butt welds as described in Embodiment 1, Embodiment 2, or Embodiment 3, applied to the welding of butt welds in excavators.

[0043] Example 5 This embodiment provides a welding method for butt welds, employing a fixing fixture for ceramic spacers used in butt welds as described in Embodiment 1, Embodiment 2, or Embodiment 3, including the following: Embed and fix the molten pool plate 8 (steel molten pool plate) into the bottom of the weld 5, and insert the perforated ceramic pad 7 into the molten pool plate; Loosen the fasteners, move the first bracket and / or the second bracket, pull the first bracket and the second bracket apart to the maximum distance, engage the retainer 4 at the first bracket with the ceramic pad on one side, move the second bracket relative to the first bracket, and move one end of the second bracket along the slide groove of the protrusion so that the retainer 4 at the second bracket engages with the ceramic pad 7 on the other side, thereby making the first bracket and the second bracket mounted on the weld side of the component (referring to the longer side of the first section and the third section of the first bracket and the second bracket being higher than the upper surface of the component 6). Fasteners secure the first bracket 1 and the second bracket 2, making the first bracket and the second bracket a single structural component; Weld seam 5 using a welding torch; After the weld is completed, loosen the fasteners, remove the first and second brackets, and then remove the ceramic pad relative to the molten pool plate.

[0044] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
