[0002] Welding the boom of many large excavators is very troublesome. Especially after welding the external welds, there are many internal welds that need to be welded. At this time, people need to drill into the inside of the boom for welding. Sometimes the welding angle is also restricted, which is not only dangerous but also inconvenient to operate. At the same time, there are also internal welds on the other side. After welding one side, it is necessary to turn it over to the other side for operation. This greatly increases the difficulty of the work, the welding quality cannot be well controlled, and the safety cannot be effectively guaranteed. Therefore, there is an urgent need for a tilting turning machine that can tilt left and right, is convenient to operate, safe and reliable. This turning machine can facilitate the operation of workers, improve production efficiency, ensure the welding quality of products, and also ensure the safety of staff. Content of the Utility Model

[0004] To achieve the above purpose, the utility model provides the following technical solution: A tilting turning machine for welding the middle part of a large boom, including a box body bracket, a turning box body and a reduction motor. The top of the box body bracket is installed with a turning box body through a rotating shaft. One side of the top of the turning box body is fixedly installed with a fixed clamping tooling. One side of the turning box body is fixedly installed with a sector gear. An electric slide rail is arranged on the top of the turning box body. A sliding clamping tooling is arranged on the top of the electric slide rail. A reduction motor is installed on one side of the box body bracket. The output end of the reduction motor is meshed with the sector gear. Ground safety limit devices are arranged on both sides of the box body bracket.
[0005] During use, the turning box body is turned 90°, so that the fixed clamping tooling is parallel to the ground. Then the middle part of the product boom is placed on the fixed clamping tooling in parallel by a crane. Click the clamping button on an external remote controller (not shown in the figure), and the sliding clamping tooling will move towards the product to clamp the product. At this time, click the turning button on the remote controller to control the operation of the reduction motor. The reduction motor drives the sector gear and then drives the turning box body to turn. At this time, the product will slowly turn to the other side. During the turning process, as long as the button is released, the product will stop immediately. When it turns to the other side and touches the ground safety limit device, it will also stop. At this time, the product is basically parallel to the ground. This device does not require staff to drill into the inside of the boom for welding, and the welding angle can be adjusted under the control of the staff without restriction, which is also convenient for the staff to operate, ensuring the welding quality of the product and the safety of the staff at the same time.
[0006] Preferably, a product anti-scratch bracket is installed on the top of the flipping box body, and a rubber roller is installed on the top of the product anti-scratch bracket.
[0007] The product anti-scratch bracket is used to support the product. The contact surface is cylindrical, which can reduce the contact surface with the product and play a role in protecting the appearance of the product. The bottom of the product is supported by the cooperation of the product anti-scratch bracket and the rubber roller, avoiding scratches between the bottom of the product and the flipping box body.
[0008] Preferably, the ground safety limit device, the electric slide rail, and the reduction motor are all electrically connected to an external controller. Since the ground safety limit device, the electric slide rail, and the reduction motor are all electrically connected to the external controller, it is convenient for the staff to input operation instructions to the internal electrical equipment of the device through the external controller to control the operation of the device.
[0009] Preferably, a protective cover is installed outside the reduction motor.
[0010] The protective cover can protect the external components of the reduction motor, improve the safety of the reduction motor during operation, and the setting of the protective cover needs to fully consider the heat dissipation of the reduction motor to ensure the stable operation of the reduction motor.
[0011] In summary, the present application includes the following beneficial technical effects:
[0012] In the present utility model, the reduction motor drives the sector gear to drive the flipping box body to flip. At this time, the product will slowly flip to the other side, and the rotation angle is controlled by the staff remotely.

[0031] Embodiment 1
[0032] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, a large boom middle welding tilting positioner proposed by the utility model includes a box body support 1, a flipping box body 2 and a reduction motor 4. The top of the box body support 1 is installed with the flipping box body 2 through a rotating shaft. The box body support 1 is used to support the entire flipping box body 2 and install the reduction motor 4. The reduction motor 4 is installed on the box body support 1 to reduce the floor area. One side of the top of the flipping box body 2 is fixedly installed with a fixed clamping tooling 201. One side of the flipping box body 2 is fixedly installed with a sector gear 3. Because the product only needs to be flipped by plus or minus 90°, a sector design is adopted, which reduces the use of raw materials for making gears and reduces the occupied space area, preventing interference and collision with the product. An electric slide rail 6 is arranged on the top of the flipping box body 2. A sliding clamping tooling 601 is arranged on the top of the electric slide rail 6. The sliding clamping tooling 601 can move back and forth on the electric slide rail 6, which is convenient for loading and unloading the product and clamping the product. A reduction motor 4 is installed on one side of the box body support 1. The output end of the reduction motor 4 is engaged with the sector gear 3. Ground safety limit devices 5 are arranged on both sides of the box body support 1.
[0033] The working principle of the large boom middle welding tilting positioner based on Embodiment 1 is as follows: When in use, the flipping box body 2 is flipped by 90° to make the fixed clamping tooling 201 parallel to the ground. Then, the middle part of the product boom is placed parallel on the fixed clamping tooling 201 by a crane. Click the clamping button on the external remote controller (not shown in the figure), and the sliding clamping tooling 601 will move towards the product to clamp the product. At this time, click the flipping button on the remote controller to control the operation of the reduction motor 4. The reduction motor 4 drives the sector gear 3 and then drives the flipping box body 2 to flip. At this time, the product will slowly flip to the other side. During the flipping process, as long as the button is released, the product will stop immediately. When flipping to the other side and touching the ground safety limit device 5, it will also stop. At this time, the product is basically parallel to the ground. This device does not require the staff to get into the inside of the boom for welding, and the welding angle can be adjusted under the control of the staff without restriction, which is also convenient for the staff to operate, ensuring the welding quality of the product and the safety of the staff at the same time.
[0034] Embodiment 2
[0035] As Figure 1 , Figure 5As shown, the utility model proposes a large-scale boom mid-section welding tilting and positioner. Compared with the first embodiment, this embodiment also includes: a product anti-scratch bracket 202 is installed on the top of the flip box 2, and a rubber roller 203 is installed on the top of the product anti-scratch bracket 202. The ground safety limit device 5, the electric slide rail 6, and the reduction motor 4 are all electrically connected to the external controller, and a protective cover is installed on the outside of the reduction motor 4.
[0036] In this embodiment, Figure 1 , Figure 5 As shown, the product anti-scratch bracket 202 is used to support the product. The contact surface is cylindrical, which can reduce the contact surface with the product and protect the product appearance. The product anti-scratch bracket 202 cooperates with the rubber roller 203 to support the bottom of the product to prevent the bottom of the product from being scratched by the flip box 2; Figure 1 As shown, since the ground safety limit device 5, the electric slide rail 6, and the reduction motor 4 are all electrically connected to the external controller, it is convenient for the staff to input operating instructions to the internal electrical equipment of the device through the external controller to control the operation of the device; Figure 1 As shown, the protective cover can protect the external components of the reduction motor 4, thereby improving the safety of the reduction motor 4 during operation. In addition, the setting of the protective cover needs to fully consider the heat dissipation of the reduction motor 4 to ensure the stable operation of the reduction motor 4.
