Description

Technical Field

[0001] This utility model belongs to the field of welding tooling technology, and in particular relates to a multi-hole positioning welding tooling. Background Technology

[0002] Multi-hole positioning welding fixtures are a general term for universal multi-hole positioning platforms and tooling fixtures. They are typically designed according to specific welding tasks and workpiece shapes, and are mainly used to play a supporting and assisting role in the assembly and welding process of welded structures. Multi-hole positioning welding fixtures are usually used in conjunction with robotic arms for welding processing. The robotic arms can complete welding tasks efficiently and accurately, improving production efficiency and quality. The universal multi-hole positioning platform is usually designed with multiple holes, which can be combined and configured according to different needs to adapt to workpieces of various shapes and sizes. The main function of the tooling fixture is to fix and position the workpiece to ensure accurate positioning of the workpiece during the welding process. It can provide accurate positioning support and fixation to ensure that the position and angle of the welding material meet the requirements.

[0003] The problem with existing technology is that when multi-hole positioning welding fixtures carry materials for welding, the materials will generate spatter during the welding process. If no shielding or protective measures are taken, the scattered spatter may contain high-temperature metal particles, which may affect the safety of the operator. Summary of the Invention

[0004] To address the problems existing in the prior art, this utility model provides a multi-hole positioning welding fixture, which has the advantage of shielding and protecting the welding table during welding to prevent welding from affecting the operator. It solves the problem that when the existing multi-hole positioning welding fixture is used to carry materials for welding, the materials will generate spatter during the welding process. If no shielding and protection measures are taken, the scattered spatter may contain high-temperature metal particles, which may affect the safety of the operator.

[0005] This utility model is implemented as follows: a multi-hole positioning welding fixture includes a welding table, a fixing plate, a protective plate, a connecting groove, and a fixing structure. The outer surface of the welding table has a plurality of positioning holes equidistantly spaced. The top of the welding table is provided with a plurality of positioning clamps. The surface of each positioning clamp has a plurality of positioning grooves, and positioning pins are inserted into the inner walls of the positioning grooves. The positioning clamps are fixedly connected to the outer surface of the welding table via the positioning pins. Fixing plates are respectively provided on the left and right sides of the welding table. The bottom of each of the two fixing plates has a fixing groove, and positioning pins are inserted into the inner walls of each fixing groove. The fixing plates are fixedly connected to the left and right sides of the welding table by positioning pins. Protective plates are rotatably connected to the sides of the two fixing plates that are close to each other by a rotating shaft. Observation windows are fixedly connected to the front of the two protective plates. A limit block is fixedly connected to the right side of the left protective plate. A limit groove is opened on the right side of the limit block. A connecting groove is opened on the left side of the right protective plate. The limit block is inserted into the inner wall of the connecting groove. A linear movement groove is opened on the front of the left end of the right protective plate. A linear movement rod is fixedly connected to the upper and lower sides of the inner wall of the connecting groove. A fixing structure is provided on the inner wall of the connecting groove.

[0006] In a preferred embodiment of this invention, the fixing structure includes a displacement block disposed on the front of the right protective plate. The outer surface of the displacement block is slidably connected to the inner wall of the straight displacement groove. A straight displacement member is fixedly connected to the front of the displacement block, and a displacement arm is fixedly connected to the back of the displacement block. By setting the displacement block, when the straight displacement member is pushed to the right, it can drive the displacement block to slide in the straight displacement groove, thereby driving the displacement arm to move.

[0007] In a preferred embodiment of this invention, the displacement arm is disposed on the inner wall of the connecting groove, the front of the displacement arm is fixedly connected to the back of the displacement block, and the upper and lower ends of the back of the displacement arm are respectively fixedly connected to force-applying rods. The outer surfaces of the two force-applying rods are respectively fitted with force-applying arms. By setting the displacement arm, the displacement arm can be driven by the displacement block to move to the right in the connecting groove, thereby driving the two force-applying rods to move. In this way, the two moving force-applying rods respectively drive the two force-applying arms to rotate.

[0008] In a preferred embodiment of this invention, the two force-applying arms are respectively positioned vertically on the inner wall of the connecting groove. The ends of the two force-applying arms that are far apart from each other are rotatably connected to the inner wall of the connecting groove via a rotating shaft. The surfaces of the ends of the two force-applying arms that are close to each other are respectively provided with force-applying grooves. The inner walls of the two force-applying grooves are respectively in contact with the outer surfaces of the two force-applying rods. The ends of the two force-applying arms that are far apart from each other are respectively fixedly connected to follower arms. By setting the force-applying arms, the two force-applying rods squeeze the two force-applying grooves while moving to the right, thereby driving the two force-applying arms to rotate relative to each other. Thus, when the two force-applying arms rotate, they respectively drive the two follower arms to rotate in the same direction.

[0009] In a preferred embodiment of this invention, the right ends of the two follower arms are fixedly connected to the left side of the two force-applying arms at opposite ends. The left ends of the two follower arms are each provided with an opening, and the left ends of the two follower arms are each provided with a stop arm on the side that is close to each other. By providing the follower arms, the two follower arms can stagger the linear rod through the openings during rotation and push the two stop arms respectively, so that the two stop arms move closer together under the force.

[0010] In a preferred embodiment of this invention, the two braking arms are slidably connected to the outer surface of the linear rod at their midpoints. The sides of the two braking arms that are far apart from each other are respectively in contact with the two follower arms. The sides of the two braking arms that are close to each other are fixedly connected to a braking spring. The braking spring is sleeved on the outer surface of the linear rod. The left ends of the two braking arms are respectively fixedly connected to a braking block. By setting the braking arms, the two braking arms are pushed by the follower arms, slide close on the linear rod, and compress the braking spring. The sliding of the two braking arms then drives the two braking blocks to move closer.

[0011] As a preferred embodiment of this utility model, the two blocking blocks are respectively fixedly connected to the left ends of the two blocking arms on opposite sides. The opposite ends of the two blocking blocks are respectively inserted into the inner wall of the limiting groove. By setting the blocking blocks, the two blocking blocks can be disengaged from the limiting groove when they move closer together, thereby releasing the fixing of the limiting blocks and thus releasing the fixed connection between the two protective plates.

[0012] 1. This utility model achieves the solution to the problem that when existing multi-hole positioning welding fixtures are used to weld materials, the materials will generate spatter during the welding process. If no shielding or protective measures are taken, the scattered spatter may contain high-temperature metal particles, which may affect the safety of the operator.

[0013] 2. This utility model, by setting a fixing plate and a protective plate, enables the connecting groove and the fixing structure to work together. The fixing structure fixes the limiting block inserted into the connecting groove, thereby fixing the two protective plates together. In conjunction with the two fixing plates, the material being welded is shielded to achieve the function of protection. This ensures that the spatter generated during the welding process can be blocked, preventing the high-temperature particles in the spatter from contacting the operator and ensuring the operator's safety.

[0019] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0020] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown in the figure, a multi-hole positioning welding fixture provided by this utility model includes a welding table 1, a fixing plate 2, a protective plate 3, a connecting groove 4, and a fixing structure 5. A plurality of positioning holes 101 are equidistantly opened on the outer surface of the welding table 1. A plurality of positioning clamps 102 are provided on the top of the welding table 1. A plurality of positioning grooves 103 are opened on the surface of the positioning clamps 102. Positioning pins 104 are inserted into the inner wall of the positioning grooves 103. The positioning clamps 102 are fixedly connected to the outer surface of the welding table 1 by the positioning pins 104. Fixing plates 2 are respectively provided on the left and right sides of the welding table 1. Fixing grooves 201 are respectively opened on the bottom of the two fixing plates 2. The inner walls of the fixing grooves 201 are respectively inserted into the grooves 103. The welding table 1 is fixedly connected to the left and right sides of the welding table 1 by positioning pins 104. The two fixed plates 2 are respectively connected to the protective plates 3 by rotating shafts on the side of the two fixed plates 2 that are close to each other. The front of the two protective plates 3 are respectively fixedly connected to observation windows 301. The right side of the left protective plate 3 is fixedly connected to a limit block 6. A limit groove 601 is opened on the right side of the limit block 6. A connecting groove 4 is opened on the left side of the right protective plate 3. The limit block 6 is inserted into the inner wall of the connecting groove 4. A straight sliding groove 7 is opened on the front of the left end of the right protective plate 3. A straight sliding rod 401 is fixedly connected to the upper and lower sides of the inner wall of the connecting groove 4. A fixing structure 5 is provided on the inner wall of the connecting groove 4.

[0022] refer to Figure 2 and Figure 4 The fixed structure 5 includes a displacement block 8, which is disposed on the front of the right protective plate 3. The outer surface of the displacement block 8 is slidably connected to the inner wall of the straight displacement groove 7. A straight displacement member 9 is fixedly connected to the front of the displacement block 8, and a displacement arm 10 is fixedly connected to the back of the displacement block 8.

[0023] The above scheme is adopted: by setting the shift block 8, when the straight shift member 9 is pushed to the right, it can drive the shift block 8 to slide in the straight shift groove 7, and the sliding shift block 8 can drive the shift arm 10 to move.

[0024] refer to Figure 4 The shifting arm 10 is disposed on the inner wall of the connecting groove 4. The front of the shifting arm 10 is fixedly connected to the back of the shifting block 8. The upper and lower ends of the back of the shifting arm 10 are respectively fixedly connected to the force-applying rods 11, and the outer surfaces of the two force-applying rods 11 are respectively sleeved with force-applying arms 12.

[0025] The above scheme is adopted: by setting up a shifting arm 10, the shifting arm 10 can be driven by the shifting block 8 to move to the right in the connecting groove 4, and at the same time drive the two force-applying rods 11 to move. In this way, the two moving force-applying rods 11 respectively drive the two force-applying arms 12 to rotate.

[0026] refer to Figure 4 Two force-applying arms 12 are respectively set on the inner wall of the connecting groove 4. The ends of the two force-applying arms 12 that are far apart from each other are rotatably connected to the inner wall of the connecting groove 4 through a rotating shaft. The surfaces of the ends of the two force-applying arms 12 that are close to each other are respectively provided with force-applying grooves 13. The inner walls of the two force-applying grooves 13 are respectively in contact with the outer surfaces of the two force-applying rods 11. The ends of the two force-applying arms 12 that are far apart from each other are respectively fixedly connected with follower arms 14.

[0027] The above scheme is adopted: by setting up the force-applying arm 12, the two force-applying rods 11 press the two force-applying grooves 13 while moving to the right, thereby driving the two force-applying arms 12 to rotate relative to each other. In this way, when the two force-applying arms 12 rotate, they respectively drive the two follower arms 14 to rotate.

[0028] refer to Figure 4 The right ends of the two follower arms 14 are fixedly connected to the left side of the two force-applying arms 12 at opposite ends. The left ends of the two follower arms 14 are respectively provided with openings 15, and the left ends of the two follower arms 14 are respectively provided with blocking arms 16 on the side that are close to each other.

[0029] The above scheme is adopted: by setting follower arms 14, the two follower arms 14 can be staggered from the linear rod 401 through the opening 15 during rotation, and push the two blocking arms 16 respectively, so that the two blocking arms 16 move closer to each other under the force.

[0030] refer to Figure 4 The two stop arms 16 are slidably connected to the outer surface of the linear rod 401 in the middle. The two stop arms 16 are respectively attached to the two follower arms 14 on the side away from each other. The two stop arms 16 are fixedly connected to the stop spring 17 on the side close to each other. The stop spring 17 is sleeved on the outer surface of the linear rod 401. The left end of the two stop arms 16 is fixedly connected to the stop block 18.

[0031] The above scheme is adopted: by setting the stop arms 16, the two stop arms 16 are pushed by the follower arms 14 respectively, slide close on the linear rod 401, and squeeze the stop spring 17 for compression. The two stop arms 16 slide and then drive the two stop blocks 18 to move closer.

[0032] refer to Figure 3 and Figure 4 Two actuating blocks 18 are fixedly connected to the left ends of the two actuating arms 16 on opposite sides, and the opposite ends of the two actuating blocks 18 are respectively inserted into the inner wall of the limiting groove 601.

[0033] The above solution is adopted: by setting the blocking blocks 18, the two blocking blocks 18 can be disengaged from the limiting groove 601 when they move closer to each other, thereby releasing the fixing of the limiting block 6 and thus releasing the fixed connection between the two protective plates 3.

[0034] In use, the two fixed plates 2, along with the two protective plates 3, are moved to the left and right sides of the welding table 1, respectively. The protective plates 3 are then rotated forward to open. The positioning pins 104 are then inserted into the fixing slots 201, and, in conjunction with the positioning holes 101 on the welding table 1, the left fixed plate 2 is fixed to the left side of the welding table 1. Similarly, the right fixed plate 2 is fixed to the right side of the welding table 1 using the positioning pins 104, allowing the two protective plates 3 to align. This allows the limiting block 6 to be inserted into the connecting slot 4. As the limiting block 6 is inserted into the connecting slot 4, it presses against the two protective plates 3. The surface of the actuating block 18 is moved, causing the two actuating arms 16 to slide closer on the linear rod 401 and compress the actuating spring 17. When the limiting block 6 is fully inserted into the connecting groove 4, the actuating spring 17 pushes the two actuating arms 16 to slide, causing the two actuating blocks 18 to move and insert into the inner wall of the limiting groove 601 to fix the actuating blocks 18. This fixes the two protective plates 3 together. Then the material to be welded can be placed on the welding table 1, and the other positioning clamps 102 can be positioned by the positioning pins 104. The material is fixed to the welding table 1 through the positioning hole 101 and closely adhered to it, thus fixing and limiting the material. Finally, the fixed material can be welded. During the process, the operator can observe the welding progress through the observation window 301 and isolate flying debris through the protective plate 3. After welding, the linear movement component 9 is pushed to the left, causing the displacement block 8 to slide to the right in the linear movement groove 7, and the displacement arm 10 to move to the right in the connecting groove 4. Simultaneously, this moves the two force-applying rods 11. The two force-applying rods 11 move to the right while simultaneously pressing against the two force-applying grooves 13, thus... The two force-applying arms 12 are driven to rotate relative to each other, and during the rotation, the two follower arms 14 are driven to rotate accordingly. During the rotation of the two follower arms 14, they are offset from the straight-moving rod 401 through the opening 15, and push the two blocking arms 16 to slide closer. While the two blocking arms 16 slide, they squeeze the blocking spring 17 to compress it, and drive the two blocking blocks 18 to move away from the limiting groove 601, thereby releasing the fixation of the limiting block 6, thereby releasing the fixed connection between the two protective plates 3. Finally, the positioning pins 104 on both sides are removed to remove the two fixed plates 2.

[0035] It should be noted that the welding table 1, the positioning fixture 102 and the positioning pin 104 are existing devices or equipment in the prior art, or are devices or equipment that can be implemented in the prior art. Furthermore, the specific composition and principle of the power supply of the welding table 1, the positioning fixture 102 and the positioning pin 104 are clear to those skilled in the art, so they will not be described in detail here.

[0036] In summary, this multi-hole positioning welding fixture, through the coordinated operation of the welding table 1, fixing plate 2, protective plate 3, connecting groove 4, and fixing structure 5, solves the problem that when the multi-hole positioning welding fixture is used to carry materials for welding, the materials will generate spatter during the welding process. If no shielding or protective measures are taken, the scattered spatter may contain high-temperature metal particles, which may affect the safety of the operator.
