Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery welding technology, and in particular relates to a welding fixture for a harvester ring plate component suitable for welding robotic arms. Background Technology

[0002] With the continuous development of agricultural mechanization, harvesters, as important agricultural production equipment, contain many complex components in their structure. The ring plate component is one of them, and this ring plate component usually requires precise welding processes to ensure its strength and stability.

[0003] The harvester ring component of the combine harvester is ring-shaped, and the weld seam is concentrated at the junction of the top of the arc plate and the middle vertical plate (both sides). The conventional welding process is to place the workpiece flat in the fixture for welding. After welding one side of the weld seam, the workpiece needs to be flipped over and placed in a second fixture to weld the other side of the weld seam. This method is not only inefficient, but also makes it difficult to guarantee the stability of the welding quality.

[0004] To address these issues, we propose a welding fixture for harvester ring plate components suitable for robotic arm welding. Utility Model Content

[0005] The purpose of this invention is to solve the problem that conventional welding processes in the prior art require adjustment of the welding surface, and to propose a welding fixture for harvester ring plate components suitable for robotic arm welding.

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

[0007] A welding fixture for a harvester ring plate component suitable for robotic welding includes a base. A second arc-shaped partition and a first arc-shaped partition are fixedly connected to the upper surface of the base. A large arc-shaped pressure plate is engaged with the interior of both the second and first arc-shaped partitions. The outer surface of the large arc-shaped pressure plate is fixedly connected to the first arc-shaped partition. A fixed seat is fixedly connected to the front of the first arc-shaped partition. Several identical bases are arranged above the base. Each base has a Y-shaped tie rod and an elliptical frame movably hinged to its inner wall. Each Y-shaped tie rod has a movable frame movably hinged to its inner wall. The inner wall of each movable frame is movably hinged to the outer surface of the elliptical frame. One of the elliptical frames... The base has bolts inside, and several other elliptical frames have two bolts inside. Each bolt has two nuts threaded onto its outer surface. The upper surface of the base is fixedly connected to two clamping frames. The inner wall of each clamping frame is movably hinged with an arc-shaped clamping claw. The upper surface of the first arc-shaped partition is provided with an annular plate part. The bottom surface of each arc-shaped clamping claw is in contact with the outer surface of the annular plate part. The front of the first arc-shaped partition is fixedly connected to several identical extrusion seats. The inner walls of three sets of extrusion seats are movably hinged with extrusion blocks. The outer surface of each extrusion block is in contact with the outer surface of the annular plate part. The bottom surface of one of the bolts is fixedly connected to a stabilizing plate.

[0008] Preferably, each bolt has two washers on its outer surface, the outer surface of each washer is in contact with the outer surface of the elliptical frame, the outer surface of each extrusion block is in contact with the outer surface of the annular plate part, one set of bolts has its outer surface in contact with the outer surface of the second arc-shaped partition, and the other two sets of bolts have their outer surfaces in contact with the outer surface of the annular plate part.

[0009] Preferably, a rubber sleeve is fixedly connected to the outer surface of each Y-shaped tie rod, and the outer surface of one set of the bases is fixedly connected to the back of the first arc-shaped partition, while the outer surfaces of the other two sets of the bases are fixedly connected to the outer surface of the large arc pressure plate.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] By setting up a base, a large circular arc pressure plate, a first arc-shaped partition, and a second arc-shaped partition, the annular plate component can be snapped into the interior of the first and second arc-shaped partitions and contact the upper surface of the large circular arc pressure plate. Through a movable frame, a base, a Y-shaped tie rod, an elliptical frame, nuts, and bolts, the movable frame and elliptical frame are moved by the Y-shaped tie rod. The movement of the elliptical frame causes the bolts and nuts to form a pressing structure that contacts the surface of the second arc-shaped partition and the surface of the stabilizing plate, respectively. The stabilizing plate causes the gasket to contact the upper surface of the arc-shaped clamping claw. The arc-shaped clamping claw is subjected to force and contacts the surface of the annular plate component, thus fixing the annular plate component vertically.

[0026] 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.

[0027] Reference Figure 1-10 A welding fixture for a harvester ring plate component suitable for robotic welding includes a base 1. A second arc-shaped partition 21 and a first arc-shaped partition 3 are fixedly connected to the upper surface of the base 1. A large arc pressure plate 2 is clamped together inside the second arc-shaped partition 21 and the first arc-shaped partition 3. Two connecting plates 20 are arranged above the base 1. The inner walls of the second arc-shaped partition 21 and the first arc-shaped partition 3 are fixedly connected to the outer surface of the connecting plates 20. By using the connecting plates 20, the stability of the second arc-shaped partition 21 and the first arc-shaped partition 3 can be increased, thereby improving the performance of the device.

[0028] A first arc-shaped partition 3 is fixedly connected to the outer surface of the large arc pressure plate 2. A fixed seat 7 is fixedly connected to the front of the first arc-shaped partition 3. Several identical bases 12 are set above the base 1. A Y-shaped tie rod 13 and an elliptical frame 14 are movably hinged to the inner wall of each base 12. A movable frame 18 is movably hinged to the inner wall of each Y-shaped tie rod 13. A rubber sleeve 19 is fixedly connected to the outer surface of each Y-shaped tie rod 13. The outer surface of one set of bases 12 is fixedly connected to the back of the first arc-shaped partition 3. The outer surfaces of the other two sets of bases 12 are fixedly connected to the outer surface of the large arc pressure plate 2. The rubber sleeve 19 makes it convenient for the operator to apply force to the Y-shaped tie rod 13, thereby improving the effectiveness of the device.

[0029] The inner wall of each movable frame 18 is hinged to the outer surface of the elliptical frame 14. One elliptical frame 14 has a bolt 15 inside, and the other elliptical frames 14 have two bolts 15 inside. The outer surface of each bolt 15 is threaded with two nuts 17. The upper surface of the base 1 is fixedly connected to two clamping base frames 10. The outer surface of each clamping base frame 10 is fixedly connected to a fixing frame 11. The bottom surface of each fixing frame 11 is fixedly connected to the upper surface of the base 1. The fixing frame 11 can be used to fix the clamping base frame 10, so as to avoid the clamping base frame 10 from vibrating during use, which would affect the stability of the clamping base frame 10.

[0030] Each clamping base 10 has an arc-shaped clamping claw 9 movably hinged to its inner wall. An annular plate part 4 is provided on the upper surface of the first arc-shaped partition 3. The bottom surface of each arc-shaped clamping claw 9 is in contact with the outer surface of the annular plate part 4. Several identical extrusion seats 5 are fixedly connected to the front of the first arc-shaped partition 3. Extrusion blocks 8 are movably hinged to the inner walls of the three sets of extrusion seats 5. The outer surface of each extrusion block 8 is in contact with the outer surface of the annular plate part 4. A stabilizing plate 6 is fixedly connected to the bottom surface of one of the bolts 15. A protective pad 22 is fixedly connected to the bottom surface of the stabilizing plate 6. The upper surface of each arc-shaped clamping claw 9 is in contact with the bottom surface of the pad 16. The protective pad 22 can buffer and protect the arc-shaped clamping claw 9, preventing the arc-shaped clamping claw 9 from being damaged by extrusion.

[0031] The outer surfaces of the other bolts 15 are in contact with the outer surface of the second arc-shaped partition 21. Two washers 16 are fitted on the outer surface of each bolt 15. The outer surface of each washer 16 is in contact with the outer surface of the elliptical frame 14. The outer surface of each extrusion block 8 is in contact with the outer surface of the annular plate part 4. The outer surface of one set of bolts 15 is in contact with the outer surface of the second arc-shaped partition 21, and the outer surfaces of the other two sets of bolts 15 are in contact with the outer surface of the annular plate part 4. The washers 16 can increase the contact area between the washers 16 and the elliptical frame 14, thereby increasing the stability of the connection between the nut 17 and the elliptical frame 14.

[0032] The working principle of this utility model is as follows: During use, the operator attaches the large arc pressure plate 2 inside the first arc-shaped partition 3 and the second arc-shaped partition 21, and places the annular plate part 4 on the upper surface of the large arc pressure plate 2. Then, utilizing the movable relationship between the extrusion block 8 and the extrusion seat 5, the angle of the extrusion seat 5 is adjusted to make the outer surface of the extrusion seat 5 fit more closely with the outer surface of the annular plate part 4. The operator then applies a pulling force to the rubber sleeve 19, which drives the Y-shaped pull rod 13 to move. The Y-shaped pull rod 13 is then hinged to the base 12 and the movable frame 18, respectively. The Y-shaped pull rod 13 applies a force to the movable frame 18. Due to the movement of the movable frame 18 and the elliptical frame 14, the movable frame 18 applies a certain force to the elliptical frame 14. Under the action of the movable hinge relationship of the base 12, the elliptical frame 14 drives the extrusion structure composed of the bolt 15, nut 17, and washer 16 to engage with the second arc-shaped partition 21. The outer surface of the ring plate part 4 and the outer surface of the stabilizing plate 6 come into contact, thereby compressing the surface of the second arc-shaped partition 21. The second arc-shaped partition 21 is compressed and the force is transmitted to the outer surface of the ring plate part 4. Since the outer surface of the ring plate part 4 is also subjected to the force of the fixing structure composed of the extrusion block 8, the extrusion seat 5 and the first arc-shaped partition 3, the ring plate part 4 can be well fixed in the back-and-forth action between the two. When the stabilizing plate 6 is subjected to a downward force, the stabilizing plate 6 applies the force to the surface of the arc-shaped clamping claw 9. The arc-shaped clamping claw 9 is subjected to downward pressure, and the contact between the arc-shaped clamping claw 9 and the outer surface of the ring plate part 4 is more reliable, avoiding the problem of shaking of the ring plate part 4 during the welding process. At the same time, the welding position is in a state of exposed sides, and the welding position can be easily welded by changing the position of the welding machine, thereby improving the use effect of the device.
