Description

Technical Field

[0001] This utility model relates to an auxiliary device for welding the front outriggers of a rice harvester, belonging to the field of agricultural machinery processing technology. Background Technology

[0002] The frame is a major component of the rice harvester, serving as the carrier for all its parts. The front outrigger assembly is a crucial part of the frame. Current methods for welding the front outrigger assembly require positioning fixtures to position and clamp the crossbeam and the two outriggers, thus enabling welding and improving precision. However, due to the unique structure of the front outrigger assembly—a figure-eight shape with a crossbeam and the distinctive shape of the connecting outriggers—existing positioning aids struggle to accurately position such uniquely shaped components. Most methods rely on simple fixtures and manual positioning or clamping for welding the front outrigger assembly, which compromises quality and is time-consuming and labor-intensive.

The support leg positioning and clamping assemblies include a first support leg positioning mechanism, a second support leg positioning mechanism, a first support leg outer side clamping mechanism, a support leg inner side clamping mechanism, a support leg pressing mechanism, and a support leg notch positioning mechanism. The first support leg positioning mechanism is used to support the upper part of the bottom surface of the support leg, and the second support leg positioning mechanism is used to support the lower part of the bottom surface of the support leg.

There are two sets of support leg pressing mechanisms. The two sets of support leg pressing mechanisms are used to press the upper and lower parts of the support leg, respectively. The support leg notch positioning mechanism is used to position the positioning notch at the bottom of the support leg.

[0005] The beneficial effects of this utility model are as follows: This utility model supports, positions and clamps the crossbeam of the front outrigger and the two left and right outriggers of the rice harvester by means of the crossbeam positioning and clamping assembly and the outrigger positioning and clamping assembly, thereby ensuring the accurate positioning of each component during the welding process. There is no need to use manual positioning or clamping, which improves the welding accuracy and welding efficiency and reduces the labor intensity of workers.

[0006] Based on the above technical solution, the present invention can be further improved as follows:

[0007] Furthermore, the beam positioning and clamping assembly includes a first sliding plate, which is slidably mounted on the base plate. The first beam support and positioning mechanism, the second beam positioning mechanism, and the beam clamping mechanism are respectively mounted on the first sliding plate, and the beam clamping mechanism is mounted on the base plate.

[0008] The beneficial effects of adopting the above-mentioned further technical solution are as follows: By setting a first sliding plate, which is slidably mounted on the base plate, the position of the crossbeam positioning and clamping assembly on the base plate can be adjusted to accommodate the welding requirements of front support leg crossbeams of different sizes. Simultaneously, the first crossbeam support and positioning mechanism, the second crossbeam positioning mechanism, and the crossbeam clamping mechanism are mounted on the first sliding plate, ensuring that these mechanisms can move synchronously during position adjustments, maintaining their relative positional relationship, thereby guaranteeing the support, positioning, and clamping effects on the crossbeam. The crossbeam clamping mechanism, mounted on the base plate, can stably clamp the crossbeam, working together with the first crossbeam support and positioning mechanism to firmly fix the crossbeam. This design makes the entire welding auxiliary device more flexible and applicable, improving welding efficiency and accuracy.

[0009] Furthermore, the first crossbeam support and positioning mechanism includes a first seat plate, which is mounted on the first slide plate. The first seat plate is provided with a crossbeam support pad and a crossbeam side positioning block. The crossbeam support pad is used to support the crossbeam, and the crossbeam side positioning block is used to position the side of the crossbeam.

The crossbeam end positioning plate includes a crossbeam end positioning surface for positioning the end face of the crossbeam and a leg end positioning surface for positioning the end face of the outrigger.

[0010] The beneficial effects of adopting the above-mentioned further technical solution are as follows: Through the cooperation of the first crossbeam support and positioning mechanism and the second crossbeam positioning mechanism, the positioning and support of the bottom and sides of the crossbeam can be achieved. The crossbeam support pad in the first crossbeam support and positioning mechanism provides a stable support surface for the crossbeam, while the crossbeam side positioning block ensures the precise positioning of the crossbeam side. The crossbeam end positioning plate in the second crossbeam positioning mechanism positions the end face of the crossbeam through the crossbeam end positioning surface, ensuring the precise positioning of the crossbeam in the length direction. The first positioning surface of the leg end connected to the crossbeam is positioned through the leg end positioning surface. This first positioning surface of the leg is located on the upper part of the leg and opposite to the end face of the crossbeam. Therefore, positioning of two surfaces can be achieved through a single crossbeam end positioning plate. This ingenious design achieves precise positioning of the leg and crossbeam at the connection point. This utility model, through the above-mentioned further solution, not only improves the accuracy of crossbeam positioning but also helps maintain the relative position stability of each component during welding, thereby improving the quality and efficiency of welding.

[0012] The beneficial effects of adopting the above-mentioned further technical solutions are as follows: the crossbeam clamping pad, under the action of the crossbeam clamping cylinder, presses the top of the crossbeam, ensuring the stability of the crossbeam during the welding process. By setting the crossbeam clamping mechanism and the crossbeam pressing mechanism, this utility model can achieve firm clamping and pressing of the crossbeam, avoiding the decline in welding quality caused by the movement or shaking of the crossbeam during the welding process. Furthermore, the end faces of the crossbeam clamping block and the crossbeam side positioning block are set opposite to each other, which can ensure the accuracy of the side positioning of the crossbeam during the clamping process, further improving the welding precision.

[0013] Furthermore, the outrigger positioning and clamping assembly includes a second sliding plate, which is slidably mounted on the base plate. The first outrigger support and positioning mechanism, the second outrigger support and positioning mechanism, the outrigger inner side clamping mechanism, the outrigger pressing mechanism, and the outrigger notch positioning mechanism are respectively mounted on the second sliding plate; the first outrigger outer side clamping mechanism is mounted on the first sliding plate.

[0014] The beneficial effects of adopting the above-mentioned further technical solution are as follows: By setting a second sliding plate, which is slidably mounted on the base plate, the position of the outrigger positioning and clamping assembly on the base plate can be flexibly adjusted to adapt to the welding requirements of front outrigger assemblies of different sizes. The first outrigger support and positioning mechanism and the second outrigger support and positioning mechanism are respectively mounted on the second sliding plate to support the upper and lower parts of the bottom surface of the outrigger, ensuring the stability of the outrigger during the welding process. The first outrigger outer side clamping mechanism and the outrigger inner side clamping mechanism work together to clamp the outrigger, further improving the welding accuracy. The outrigger pressing mechanism has two sets, which respectively press the upper and lower parts of the outrigger to ensure that the outrigger will not move or shake during the welding process. The outrigger notch positioning mechanism is used to position the positioning notch at the bottom of the outrigger to achieve precise positioning of the outrigger. The above-mentioned further solution of this utility model improves the flexibility and applicability of the device, can meet the welding requirements of front outrigger assemblies of different sizes and shapes, and improves the welding efficiency and accuracy.

[0015] Furthermore, the first leg support positioning mechanism includes a first leg positioning pin; the second leg support positioning mechanism includes a fifth stand, which is mounted on the second slide plate, and a second leg support pad is rotatably mounted on the fifth stand. The second leg support pad is magnetic. The leg notch positioning mechanism includes a sixth seat plate, which is mounted on the second slide plate. A push-pull quick clamp is mounted on the sixth seat plate, and the end of the push-pull quick clamp is connected to a notch positioning plate. The notch positioning plate is mounted on the sixth seat plate via a guide post and a guide seat.

[0016] The beneficial effects of adopting the above-mentioned further technical solutions are as follows: The first leg support and positioning mechanism achieves precise positioning of the upper part of the bottom surface of the leg through the first leg positioning pin, ensuring the stability of the leg during the welding process. The second leg support pad in the second leg support and positioning mechanism not only provides a stable support surface for the leg, but its magnetic properties also attract the leg, further preventing movement or shaking during welding. The leg notch positioning mechanism, through the cooperation of a push-pull quick clamp and a notch positioning plate, can quickly and accurately position the positioning notch at the bottom of the leg, further ensuring the precise positioning of the leg; the notch positioning plate, through the installation method of guide posts and guide seats, not only ensures its stability during movement, but also makes the positioning operation smoother and more efficient.

[0018] The beneficial effects of adopting the above-mentioned further technical solution are as follows: Since the two outriggers of the rice harvester's front outrigger assembly are shaped like the number "8" and have a unique shape, this invention, by setting up a first and a second outrigger outer side clamping mechanism, acts on the outer side of the outrigger respectively. Together with the inner side clamping mechanism, they achieve all-around clamping of the outrigger, ensuring its stability and positioning accuracy during the welding process. Both the first and second outrigger outer side clamping mechanisms use cylinder-driven clamping blocks, featuring simple operation and stable, reliable clamping force. The inner side clamping mechanism clamps the inner side of the outrigger by rotating the clamping handle and the inner side clamping block, offering flexible operation and significant clamping effect. This invention improves welding precision through the above solution and also helps maintain the shape stability of the outrigger during welding, thereby improving welding quality and efficiency.

[0020] The beneficial effects of adopting the above-mentioned further technical solutions are as follows: By setting up an error-proof mechanism, this utility model can further improve the reliability and accuracy of the device. The error-proof mechanism includes an eighth support and an error-proof pin movably mounted on the eighth support. The position and state of the error-proof pin can be matched with front support leg assemblies of different specifications, thereby enabling the device to adapt to front support leg assemblies of different sizes and ensuring that the front support leg assembly can be correctly installed on the welding auxiliary device during the welding process, avoiding welding quality problems caused by incorrect installation; it not only improves the accuracy and efficiency of welding, but also helps to reduce unnecessary losses caused by operational errors.

[0022] The beneficial effects of adopting the above-mentioned further technical solutions are as follows: the outrigger clamping pad, under the action of the outrigger clamping cylinder, presses the top of the outrigger, ensuring the stability of the outrigger during the welding process; by setting up the outrigger clamping mechanism, the fixing effect of the outrigger can be further improved, avoiding a decrease in welding quality due to outrigger movement or shaking during the welding process. At the same time, the design of the outrigger clamping cylinder and the outrigger clamping pad makes the clamping operation simpler and more stable, helping to improve welding efficiency and precision.

[0023] Furthermore, a first slide rail and a second slide rail are installed on the base plate. A first slider is provided at the bottom of the first slide plate, and the first slider is slidably installed on the first slide rail. A second slider is provided at the bottom of the second slide plate, and the second slider is slidably installed on the second slide rail.
