Description

Technical Field

[0001] This utility model belongs to the field of harvester technology, and in particular relates to a welding fixture for harvester support components. Background Technology

[0002] A combine harvester is an integrated machine for harvesting crops. It completes harvesting and threshing in one go and collects the grains into a storage bin. It can also be used for manual harvesting. The straw of crops such as rice and wheat is laid out in the field and then picked up and threshed by grain harvesting machinery. It is a crop harvesting machine that harvests the grains and straw of rice, wheat and other cereal crops.

[0003] The existing utility model with authorization announcement number CN222679967U discloses a welding fixture for the main frame guide rail of a combine harvester, including a base and a main frame guide rail disposed on the base. The main frame guide rail includes a horizontal tube, a first connecting bracket disposed at the end of the horizontal tube, and a plurality of second connecting brackets disposed on one side of the horizontal tube.

[0004] Using the above technical solution, it is only necessary to place each component on the above structure, and personnel can quickly weld each component. Compared with manual welding, it greatly improves work efficiency and ensures welding quality. However, the above technical solution can only weld the same type of bracket component and cannot complete the welding of two types of brackets in one fixture, resulting in the problem of low adaptability of the welding device.

[0005] To address this issue, we propose a welding fixture for harvester support components. Utility Model Content

[0006] The purpose of this utility model is to solve the problem that in the prior art, welding work can only be carried out on the same type of bracket component, and it is not possible to complete the welding of two types of brackets in one fixture, resulting in low adaptability of the welding device. Therefore, a welding fixture for harvester bracket components is proposed.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A welding fixture for a harvester support component includes a clamping plate. Two first pressing cylinders, a second pressing cylinder, a third pressing cylinder, a fixed plate, a limiting block, a support frame, a fixing frame, and four fixing bolts are fixedly connected to the upper surface of the clamping plate. A first support component, a second support component, three rotary pressing cylinders, and two movable blocks are arranged above the clamping plate. An L-shaped support plate is fixedly connected to the front of the fixed plate, and a limiting rod is fixedly connected to the front of the limiting block. A pressing plate is fixedly connected to the telescopic end of each rotary pressing cylinder, and the inner wall of each movable block is in contact with the outer surface of the fixing bolt. Each set of fixing bolts has a fixed long plate fixedly connected to its bottom end. The bottom surface of each fixed long plate is fixedly connected to the upper surface of the clamping plate. A control device is fixedly connected to the front of the clamping plate. A first control switch, a second control switch, a third control switch, and a fourth control switch are fixedly connected to the upper surface of the control device. The first control switch is electrically connected to three rotary pressing cylinders via wires. The second control switch is electrically connected to two first pushing cylinders via wires. The third control switch is electrically connected to a second pushing cylinder via wires. The fourth control switch is electrically connected to a third pushing cylinder via wires.

[0009] Preferably, a reinforcing frame is fixedly connected to the outer surface of each of the first push-pressing cylinders, and the bottom surface of each reinforcing frame is fixedly connected to the upper surface of the clamping plate.

[0010] Preferably, each of the reinforcing frames has two fixing bolts threaded to its inner wall, and the outer surface of each set of fixing bolts is threaded to the inner wall of the clamp plate.

[0011] Preferably, a limiting plate is fixedly connected to the outer surface of one of the rotary clamping cylinders, and the bottom surface of the limiting plate is fixedly connected to the upper surface of the clamping plate.

[0012] Preferably, the outer surfaces of the second and third push-tightening cylinders are both fixedly connected with reinforcing plates, and the bottom surface of each reinforcing plate is fixedly connected to the upper surface of the clamping plate.

[0013] Preferably, a support block is fixedly connected to the bottom end of one of the rotary clamping cylinders, and the bottom surface of the support block is fixedly connected to the upper surface of the clamping plate.

[0014] In summary, the technical effects and advantages of this utility model are as follows:

[0015] By employing a combination of a first pressing cylinder, a second pressing cylinder, a third pressing cylinder, and a rotary pressing cylinder, the positions of the first and second support components can be clamped and fixed respectively, providing a strong fixing effect and enhancing the effectiveness of the device. Furthermore, by employing a combination of a fixing bolt, a movable block, a limiting block, a limiting rod, a fixing frame, and an L-shaped support plate bracket, the position of the harvester support components can be easily fixed and restricted, achieving the purpose of fixing and limiting. This effectively avoids the problem of only being able to weld the same type of support component, and thus being unable to weld two types of supports in one fixture, resulting in low adaptability of the welding device.

[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 1-6 A welding fixture for a harvester support component includes a clamping plate 1. The upper surface of the clamping plate 1 is fixedly connected to two first pressing cylinders 2, a second pressing cylinder 3, a third pressing cylinder 4, a fixing plate 10, a limiting block 19, a support frame 22, a fixing frame 24, and four fixing bolts 17. The outer surface of each first pressing cylinder 2 is fixedly connected to a reinforcing frame 12. The bottom surface of each reinforcing frame 12 is fixedly connected to the upper surface of the clamping plate 1. The first pressing cylinder 2 can be reinforced by the reinforcing frame 12, thereby enhancing the stability of the device.

[0025] The clamping plate 1 is equipped with a first support component 25, a second support component 26, three rotary clamping cylinders 5 and two movable blocks 18. The front of the fixed plate 10 is fixedly connected to an L-shaped support plate 23, and the front of the limiting block 19 is fixedly connected to a limiting rod 20. The inner wall of each reinforcing frame 12 is threaded with two fixing bolts 13. The outer surface of each set of fixing bolts 13 is threaded to the inner wall of the clamping plate 1. The position of the reinforcing frame 12 can be restricted by the fixing bolts 13 to prevent it from shifting during use.

[0026] Each rotary clamping cylinder 5 has a clamping plate 14 fixedly connected to its telescopic end. The inner wall of each movable block 18 is in contact with the outer surface of the fixing bolt 17. The bottom end of each set of fixing bolts 17 is fixedly connected to a fixing long plate 16. The bottom surface of each fixing long plate 16 is fixedly connected to the upper surface of the clamping plate 1. A limit plate 21 is fixedly connected to the outer surface of one of the rotary clamping cylinders 5. The bottom surface of the limit plate 21 is fixedly connected to the upper surface of the clamping plate 1. The position of the rotary clamping cylinder 5 can be restricted by the limit plate 21 to avoid the problem of unstable position deviation during operation.

[0027] A control device 27 is fixedly connected to the front of the clamping plate 1. A first control switch 6, a second control switch 7, a third control switch 8, and a fourth control switch 9 are fixedly connected to the upper surface of the control device 27. The first control switch 6 is electrically connected to three rotary clamping cylinders 5 through wires. A reinforcing plate 11 is fixedly connected to the outer surface of the second pressing cylinder 3 and the outer surface of the third pressing cylinder 4. The bottom surface of each reinforcing plate 11 is fixedly connected to the upper surface of the clamping plate 1. Through the reinforcing plate 11, the position of the second pressing cylinder 3 and the third pressing cylinder 4 can be reinforced to prevent them from swaying during use.

[0028] The second control switch 7 is electrically connected to the two first pressing cylinders 2 via wires. The third control switch 8 is electrically connected to the second pressing cylinder 3 via wires. The fourth control switch 9 is electrically connected to the third pressing cylinder 4 via wires. A support block 15 is fixedly connected to the bottom end of one of the rotary pressing cylinders 5. The bottom surface of the support block 15 is fixedly connected to the upper surface of the clamping plate 1. The support block 15 can fix and support the rotary pressing cylinder 5, providing strong support.

[0029] The working principle of this utility model is as follows: When welding the first support component 25 is required, the position of the first support component 25 is first restricted by the limiting rod 20, so that it can be placed on the L-shaped support plate 23, the limiting block 19 and the fixing frame 24. Then, one of the movable blocks 18 is fixed by the fixing bolt 17, thereby fixing the position of the first support component 25. Then, the extension end of the third pushing cylinder 4 is extended by the fourth control switch 9, which can further reinforce the position of the first support component 25. The first control switch 6 is used to press the first support component 25 with the rotary pressing cylinder 5, so as to achieve the purpose of fixing and limiting, which facilitates the welding work.

[0030] When welding is required on the second bracket component 26, simply adjust the position of the movable block 18, and then extend the telescopic ends of the first push cylinder 2 and the second push cylinder 3 by the second control switch 7 and the third control switch 8 respectively to fix the position of the second bracket component 26. Then repeat the steps of fixing the first bracket component 25. This can effectively avoid the problem that welding can only be performed on the same type of bracket component, and that welding of two types of brackets cannot be completed in one fixture, resulting in low adaptability of the welding device.
