Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery sheet metal welding technology, specifically a welding flipping device. Background Technology

[0002] Agricultural machinery sheet metal parts refer to various sheet metal parts that make up the structure of agricultural machinery. These parts are made through processes such as stamping, bending, and welding, and are lightweight and durable. Agricultural machinery sheet metal parts are widely used in agricultural machinery, such as the shells, frames, and support structures of equipment like tractors, harvesters, and seeders. They not only ensure the strength and stability of the machinery, but also help improve operating efficiency and safety.

[0003] Utility model patent CN219787206U discloses a flipping device for welding sheet metal parts. The device involves placing a sheet metal part on the upper surface of a flipping frame, fixing it with a threaded rotating rod and a clamping plate, and using a drive motor to flip the sheet metal part. Simultaneously, the position of the support base inside the fixed frame is adjusted, and another sheet metal part is placed on multiple movable support rods. Depending on the irregular shape of the sheet metal part, different movable support rods are pushed to slide and embed into the fixed cavity at different lengths, causing two gears to rotate relative to each other, which in turn causes a limiting frame to engage and fix the sheet metal part on its outer surface, maintaining its stability on the upper surface of the support base. Compared to existing technologies, this solution facilitates the support and fixation of sheet metal parts during welding, improves the overall welding effect after the sheet metal part is flipped and adjusted, solves the problem of welding position displacement caused by unstable placement of irregularly shaped sheet metal parts during welding, and improves the overall processing efficiency of sheet metal parts.

[0004] In this structure, the support base can move left and right to adjust the position of a sheet metal part on the support base, which is convenient for welding. However, when the sheet metal part below is not aligned front to back, it is necessary to loosen the sheet metal part, adjust its position, and then clamp it again for welding, which is a rather cumbersome process. In view of this, this application proposes a flipping device for welding. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a welding flipping device, which has the advantages of allowing a lower sheet metal part to move left, right, forward, and backward after clamping, aligning with an upper sheet metal part. This solves the problem that when the welding position of the lower sheet metal part is not aligned, it is necessary to loosen the sheet metal part, adjust its position, and then clamp it again for welding, which is a rather cumbersome process.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a welding flipping device, comprising a supporting base plate, a first adjusting base slidably mounted on the top of the supporting base plate, a slide rail fixedly mounted on the top of the first adjusting base, a second adjusting base slidably mounted on the top of the slide rail, and a bottom clamping assembly provided on the top of the second adjusting base;

[0007] The bottom clamping assembly includes two fixed upright plates fixedly installed on the top of the second adjusting base.

[0010] Furthermore, two second side plates are fixedly installed on the top of the first adjusting base, and a second screw is rotatably installed between the two second side plates. The second screw is threadedly connected to the second adjusting base, and a second motor with an output shaft fixedly connected to one end of the second screw is fixedly installed on one side of one of the second side plates.

[0011] Furthermore, two adjustable hydraulic cylinders are fixedly installed on the top of the supporting base plate, and a lifting base plate is fixedly installed on the movable end of the adjustable hydraulic cylinders. A mounting side plate is fixedly installed on the top of the lifting base plate.

[0012] Furthermore, a bearing is fixedly installed on one side of each of the two mounting side plates, and a rotating shaft passes through the inner ring of the bearing.

[0014] Furthermore, a controller is fixedly installed at the bottom of the support base plate, and an oil pipe connected to the regulating hydraulic cylinder is fixedly installed at the output end of the controller.

[0015] Compared with the prior art, the present invention provides a welding flipping device, which has the following advantages:

[0016] This welding flipping device, by installing the bottom clamping assembly onto the second adjusting base, sliding the second adjusting base onto the first adjusting base, and sliding the first adjusting base onto the support base plate, allows the bottom clamping assembly to move left, right, forward, and backward on the support base plate. This drives the sheet metal parts clamped on the bottom clamping assembly to adjust their position according to the welding position. This solves the problem that when the welding position of a sheet metal part is not aligned, it is necessary to loosen the sheet metal part, adjust its position, and then clamp it again for welding, which is a rather cumbersome process.

A workpiece is placed on the top of the second adjusting base 4, and the clamping screw 53 is rotated, causing the clamping plate 54 to move towards the center, clamping the workpiece. Depending on the welding position, the first adjusting base 2 and the second adjusting base 4 are moved to adjust the workpiece's forward, backward, left, and right movement.

[0025] Meanwhile, two first side plates 6 are fixedly installed on the top of the supporting base plate 1, and a slide rod 7 is fixedly installed between the two first side plates 6. The slide rod 7 slides through the first adjusting base 2.
