Description

Technical Field

[0001] This utility model belongs to the technical field of welding fixtures for radiator brackets of combine harvesters, and particularly relates to a gantry-type positioning fixture structure suitable for robotic arm welding. Background Technology

[0002] The radiator bracket of a combine harvester is an important structural component used to fix and support the radiator, ensuring that the radiator maintains stable and efficient operation in high-vibration and high-load working environments. Welding is required when processing the radiator bracket of the combine harvester.

[0003] When welding existing combine harvester radiator brackets, the complex shape of the brackets necessitates robust welding, accurate positioning, and minimal errors when using robotic arms. However, directly placing the radiator bracket in the desired position for welding can cause instability and wobbling, affecting the welding quality and ultimately reducing the structural strength of the radiator bracket.

[0004] To address these issues, we propose a gantry-type positioning fixture structure suitable for robotic welding. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing technologies cannot stably clamp and weld the radiator bracket of a combine harvester, and to propose a gantry-type positioning fixture structure suitable for robotic welding.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A gantry-type positioning fixture structure suitable for robotic welding includes a fixture base plate. Two sets of support blocks are fixedly connected to the upper surface of the base plate. A first bracket and a second bracket are respectively positioned above the two sets of support blocks. The outer surface of the first bracket contacts the front of the second bracket. A bent welding plate and a straight welding plate are respectively positioned above the first bracket. A connecting welding plate is positioned above the second bracket. Two I-beam supports and a blocking support are fixedly connected to the upper surface of the base plate. The right side of the blocking support contacts the left side of the first bracket. A connecting base is fixedly connected to the upper surface of each I-beam support and the upper surface of each blocking support. The inner wall of each connecting base is movably hinged with a hinge block, and the outer surface of each set of connecting bases is movably hinged with a hinge frame. The outer surface of each set of hinge blocks and the inner wall of each set of hinge frames are movably hinged with connecting blocks. A movable frame is fixedly connected to one side of each set of hinge blocks that is close to each other. An extrusion rod is rotatably connected inside each set of movable frames. The bottom ends of the two sets of extrusion rods are respectively in contact with the upper surface of the first bracket and the upper surface of the connecting welding plate. Two gantry frames are fixedly connected to the upper surface of the tooling base plate. The upper surface of the bent welding plate is in contact with the inner top wall of one of the gantry frames, and the left side of the straight welding plate is in contact with the right side of the other gantry frame.

[0008] Preferably, a baffle is fixedly connected to the front of one of the support blocks, and the back of the baffle is in contact with the front of the first bracket.

[0009] Preferably, a first stop is fixedly connected to the right side of one of the I-beam supports, the bottom surface of the first stop is fixedly connected to the upper surface of the tooling base plate, and the right side of the first stop is in contact with the left side of the second bracket.

[0010] Preferably, a second stop is fixedly connected to the front of another I-beam support, the bottom surface of the second stop is fixedly connected to the upper surface of the tooling base plate, and the front of the second stop is in contact with the back of the first bracket.

[0011] Preferably, the inner wall of the blocking support is fixedly connected with a reinforcing rib, and the bottom surface of the reinforcing rib is in contact with the upper surface of the tooling base plate.

[0012] Preferably, an extrusion assembly is fixedly connected to the upper surface of the tooling base plate, and a clamping rod is fixedly connected to the output end of the extrusion assembly. The bottom end of the clamping rod is in contact with the outer surface of the second bracket.

[0013] Preferably, a push handle is fixedly connected to the upper surface of each set of the hinge frame, and an anti-slip sleeve is provided on the outer surface of each set of the push handle.

[0014] Preferably, each of the gantry frames has two reinforcing plates fixedly connected to its outer surface, and the bottom surface of each set of reinforcing plates is fixedly connected to the upper surface of the tooling base plate.

[0015] In summary, the technical effects and advantages of this utility model are as follows:

[0016] 1. By setting up a tooling base plate, support blocks, a first bracket, a second bracket, a connecting welding plate, an I-beam support, a blocking support, a connecting base, a hinge block, a hinge frame, a connecting block, a moving frame, and a pressing rod, the tooling base plate can be used to easily connect the first bracket and the second bracket to the two sets of support blocks respectively. The connecting welding plate can be installed on the second bracket. The connecting base fixed on the I-beam support and the blocking support can be manually pushed by holding the handle to make the hinge frame move with the hinge block and the connecting block. This allows the moving frame to press the upper surface of the first bracket and the connecting welding plate with the pressing rod, thereby stably clamping the first bracket, the second bracket, and the connecting welding plate. This makes the radiator bracket of the combine harvester stable in placement and clamping, ensuring reliable welding, accurate positioning, and less error, thus improving the welding quality of the radiator bracket of the combine harvester.

[0017] 2. By setting up the cooperation of bent welding plates, straight welding plates and gantry frames, the bent welding plates and straight welding plates can be connected to the two gantry frames respectively by bolts. The bent welding plates and straight welding plates can also be installed in contact with the first support, so that the bent welding plates and straight welding plates on the first support can be welded stably. This ensures that the bent welding plates and straight welding plates outside the first support are welded firmly, accurately positioned, and less prone to errors, thereby further improving the welding quality of the combine harvester radiator support.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-4 A gantry-type positioning fixture structure suitable for robotic welding includes a fixture base plate 1. Two sets of support blocks 2 are fixedly connected to the upper surface of the fixture base plate 1. A first bracket 3 and a second bracket 4 are respectively arranged above the two sets of support blocks 2. The outer surface of the first bracket 3 is in contact with the front of the second bracket 4. A baffle 17 is fixedly connected to the front of one of the support blocks 2. The back of the baffle 17 is in contact with the front of the first bracket 3. The baffle 17, which is fixed to the front of the support block 2 by bolts, can conveniently block and limit one side of the first bracket 3, thereby facilitating the clamping and positioning of the first bracket 3.

[0025] An extrusion assembly 21 is fixedly connected to the upper surface of the tooling base plate 1. The extrusion assembly 21 includes a support, a rotatable lever, and a hinged transmission component installed on the tooling base plate 1. It can drive the clamping rod 22 to extend and retract, so as to facilitate the extrusion and clamping of the outer surface of the second bracket 4 by using the clamping rod 22. The output end of the extrusion assembly 21 is fixedly connected to the clamping rod 22. The bottom end of the clamping rod 22 is in contact with the outer surface of the second bracket 4. By manually controlling the operation of the extrusion assembly 21, the clamping rod 22 can be used to extrude the outer surface of the second bracket 4 to assist in clamping and positioning the second bracket 4.

[0026] A bent welding plate 6 and a straight welding plate 7 are respectively arranged above the first bracket 3. A connecting welding plate 5 is arranged above the second bracket 4. Two I-beam supports 8 and a blocking support 9 are fixedly connected to the upper surface of the tooling base plate 1. The right side of the blocking support 9 is in contact with the left side of the first bracket 3. A first stop block 18 is fixedly connected to the right side of one of the I-beam supports 8. The bottom surface of the first stop block 18 is fixedly connected to the upper surface of the tooling base plate 1. The right side of the first stop block 18 is in contact with the left side of the second bracket 4. The first stop block 18 is bolted to the right side of the I-beam support 8, which can conveniently block the left side of the second bracket 4, thereby facilitating the side positioning and clamping of the second bracket 4.

[0027] Another I-beam support 8 has a second stop 19 fixedly connected to its front side. The bottom surface of the second stop 19 is fixedly connected to the upper surface of the tooling base plate 1. The front side of the second stop 19 is in contact with the back side of the first bracket 3. The second stop 19 is fixed to the front side of the other I-beam support 8 with bolts. The second stop 19 fixed with bolts can easily block the back side of the first bracket 3, thereby facilitating the side positioning and clamping of the first bracket 3.

[0028] Each I-beam support 8 and the upper surface of the blocking support 9 are fixedly connected to a connecting base 10. The inner wall of each connecting base 10 is movably hinged to a hinge block 11, and the outer surface of each connecting base 10 is movably hinged to a hinge frame 13. The outer surface of each hinge block 11 and the inner wall of each hinge frame 13 are movably hinged to a connecting block 12. The sides of the two sets of hinge blocks 11 that are close to each other are fixedly connected to a moving frame 14. The inside of each moving frame 14 is rotatably connected to a pressing rod 15. The bottom ends of the two sets of pressing rods 15 are in contact with the upper surface of the first support 3 and the upper surface of the connecting welding plate 5, respectively. The inner wall of the blocking support 9 is fixedly connected to a reinforcing rib 20. The bottom surface of the reinforcing rib 20 is in contact with the upper surface of the tooling base plate 1. The reinforcing rib 20 improves the strength of the blocking support 9, thereby improving the stability of the gantry positioning tooling structure.

[0029] Each set of hinged frames 13 has a push handle 23 fixedly connected to its upper surface. Each set of push handles 23 has an anti-slip sleeve 24 on its outer surface. By manually holding the anti-slip sleeve 24, the push handle 23 can be easily and stably held by the operator, thus facilitating the operation of using this positioning fixture structure to position and clamp the radiator bracket of the combine harvester.

[0030] Two gantry frames 16 are fixedly connected to the upper surface of the tooling base plate 1. The upper surface of the bent welded plate 6 is in contact with the inner top wall of one of the gantry frames 16, and the left side of the straight welded plate 7 is in contact with the right side of the other gantry frame 16. Two reinforcing plates 25 are fixedly connected to the outer surface of each gantry frame 16. The bottom surface of each set of reinforcing plates 25 is fixedly connected to the upper surface of the tooling base plate 1. By using the reinforcing plates 25 fixed to the outside of the gantry frame 16, the reinforcing plates 25 can be connected to the upper surface of the tooling base plate 1 by bolts, thereby improving the connection stability between the gantry frame 16 and the tooling base plate 1.

[0031] The working principle of this utility model is as follows: When using this gantry-type positioning fixture structure suitable for robotic arm welding to position and clamp the radiator bracket of the combine harvester to be welded, the fixture base plate 1 of the gantry-type positioning fixture structure is first placed stably on the horizontal ground by manual means, so as to stably clamp and fix the radiator bracket of the combine harvester. Then, the I-beam support 8, the blocking support 9 and the two gantry frames 16 are fixed to the required position on the fixture base plate 1 by manual means using bolts. The baffle 17 can be fixed to one side of the support block 2 by bolts, so that the first bracket 3 and the second bracket 4 can be placed to the required position on the fixture base plate 1 by manual means.

[0032] The first support 3 can be blocked and positioned by the baffle 17 and the second stop 19, and the second support 4 can be blocked and positioned by the first stop 18. The connecting welding plate 5 is placed on the second support 4 at the required position by manual means, and the bent welding plate 6 and the straight welding plate 7 are connected to the gantry frame 16 by manual means using bolts, and the bent welding plate 6 and the straight welding plate 7 are installed on the first support 3 at the required position.

[0033] By manually controlling the extrusion assembly 21, the clamping rod 22 is used to extrude and clamp the outer surface of the second bracket 4, thereby assisting in the positioning of the second bracket 4. Finally, by manually gripping the anti-slip sleeve 24 outside the push handle 23, the hinge frame 13, which is hinged to the connecting base 10, can be moved using the push handle 23. The hinge block 11 and connecting block 12 inside the hinge frame 13 can then be used to move the moving frame 14 with the extrusion rod 15 downwards until the bottom end of the extrusion rod 15 is extruded and clamped against the upper surface of the first bracket 3 and the upper surface of the connecting welding plate 5, respectively. This allows the combine harvester radiator bracket to be clamped and fixed, ensuring reliable welding, accurate positioning, and reducing the likelihood of errors.
