[0014] Beneficial effects:
[0015] (i) The friction welding device for processing automotive motor housings uses a gas delivery network consisting of an intake manifold, a connecting pipe, and an intake branch pipe to stably deliver cooling gas to the blowing shell and spray it onto the welding area via a linear array of blowing grooves.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please refer to Figures 1-5. This utility model provides a technical solution: a friction welding device for processing automotive motor housings, comprising: a welding machine body 1, and an integrated component 2. The outer wall of the integrated component 2 is fixedly installed with the outer wall of the welding machine body 1. The integrated component 2 includes a limiting component 4. The outer wall of the limiting component 4 is fixedly installed with the outer wall of the welding machine body 1 by bolts. A cooling component 3 is slidably connected to the outer wall of the limiting component 4. The cooling component 3 includes an air blowing shell 31. An air intake branch pipe 32 is fixedly connected to the inner walls on both sides of the air blowing shell 31. The end of the air intake branch pipe 32 away from the air blowing shell 31 is fixedly connected to an air intake main pipe 33 through a connecting pipe 34. The bottom of the connecting pipe 34 is fixedly connected to the top of the air intake branch pipe 32. Cooling gas is transported to the air intake main pipe 33 through external equipment. The cooling gas transported to the air intake main pipe 33 is dispersed into the connecting pipe 34, and then transported to the air intake branch pipe 32 through the connecting pipe 34, and then into the air blowing shell 31.
[0025] The air blowing shell 31 has an air blowing groove 35 in its wall, and the air blowing groove 35 is arranged in a linear array along the outer wall of the air blowing shell 31. The outer wall of the air inlet main pipe 33 is fixedly connected to the top of the welding machine body 1 through a limiting buckle, and the side of the welding machine body 1 is fixedly connected to the outer wall of the connecting pipe 34 through a limiting buckle.
[0026] The limiting assembly 4 includes a limiting rod 44, which is provided in two sets. Each set of limiting rods 44 has a limiting post 41 fixedly connected to its top. A pin 42 is slidably connected to the top of the limiting post 41 via a ring. A fixing post 43 is slidably connected to the inner wall of the pin 42. A top spring 46 is fixedly connected to the outer wall of the fixing post 43. The side of the fixing post 43 away from the top spring 46 is fixedly connected to the outer wall of the limiting post 41 via a bracket. A fixing seat 45 is rotatably connected to the outer wall of the limiting rod 44 via a cylinder. The outer wall of the fixing seat 45 is bolted to the outer wall of the welding machine body 1. The top spring 46 is fixedly installed on the wall. The end of the top spring 46 away from the fixed post 43 is fixedly connected to the inner wall of the insertion post 42. The outer wall of the limiting rod 44 is slidably connected to the inner wall of the air blowing shell 31. The outer wall of the insertion post 42 is inserted into the outer wall of the welding machine body 1 through the limiting ring. The limiting post 41 is forced to drive the limiting rod 44 to rotate along the fixed seat 45. Then the insertion post 42 is pulled so that the insertion post 42 is aligned with the limiting ring on the welding machine body 1. Then the pulling force on the insertion post 42 is released, thereby pushing the insertion post 42 into the limiting ring on the welding machine body 1 through the top spring 46.
[0027] In the manufacturing process of automotive motor housings, friction welding is a key process that significantly impacts welding quality and production efficiency. This paper presents a friction welding device for automotive motor housing processing. Through the coordinated operation of integrated component 2, cooling component 3, and limiting component 4, the stability and reliability of friction welding are effectively improved. Its specific working principle is as follows:
[0028] Before the device is put into operation, the limiting component 4 must be fixedly installed on the outer wall of the welding machine body 1 with bolts to provide stable support and limiting foundation for subsequent components. The fixed seat 45 in the limiting component 4 is connected to the welding machine body 1 with bolts to ensure that the entire limiting structure is stable and does not shake. The two sets of limiting rods 44 extend vertically upward, and the limiting post 41 at the top plays a preliminary positioning role. The insert post 42 can slide flexibly in the ring at the top of the limiting post 41, while its inner wall slides with the fixed post 43. The top spring 46 installed between the two gives the insert post 42 a certain elastic movement space. In subsequent operation, the elastic force of the top spring 46 can help the insert post 42 better adapt to different limiting requirements and ensure stable limiting of the cooling component 3.
[0029] When preparing for friction welding of the automotive motor housing, the cooling assembly 3, with the air-blowing shell 31 as its core, has intake branch pipes 32 on both sides of its inner wall responsible for introducing cooling gas. This cooling gas is delivered to the intake manifold 33 through external equipment. The cooling gas delivered to the intake manifold 33 is dispersed into the connecting pipe 34, and then delivered to the intake branch pipes 32 through the connecting pipe 34, and then into the air-blowing shell 31. The air-blowing grooves 35 arranged in a linear array in the wall of the air-blowing shell 31 are the outlets of the cooling gas. During the friction welding process, the welding area... The intense friction will generate a large amount of heat. At this time, the cooling gas is ejected at high speed from the air blowing slot 35 and directly acts on the welding area to quickly remove the heat and cool the welding part. This avoids problems such as material performance degradation and welding deformation caused by high temperature, and ensures welding quality. At the same time, the main air inlet pipe 33 and the welding machine body 1, and the connecting pipe 34 and the side of the welding machine body 1 are fixed by limit buckles to ensure that the gas delivery pipeline is stable in position during the operation of the device and will not be displaced or fall off due to vibration or other factors, thus ensuring stable delivery of cooling gas.
[0030] During friction welding, the limiting component 4 plays a continuous role. When the workpiece, such as the car motor housing, is placed on the welding machine body 1 and welding is performed, the limiting rod 44 not only provides support for the air shell 31, but also restricts its movement in the horizontal direction, ensuring that the air groove 35 is always aligned with the welding area and ensuring the cooling effect. When the air shell 31 needs to be removed, simply rotate the limiting component 4. The insert 42, under the action of the top spring 46, limits the air shell 31. The connection structure between the fixed column 43 and the limiting column 41 further enhances the stability of the entire limiting component 4, allowing the limiting rod 44 to maintain a reliable working state during the support and limiting process.
[0031] Therefore, when it is necessary to remove the air blowing shell 31, simply move the limiting post 41 to force the limiting post 41 to drive the limiting rod 44 to rotate along the fixed seat 45, then pull the insertion post 42 so that the insertion post 42 is aligned with the limiting ring on the welding machine body 1, and then release the pulling force on the insertion post 42, thereby pushing the insertion post 42 into the limiting ring on the welding machine body 1 through the top spring 46, thus limiting the position of the limiting rod 44, and the air blowing shell 31 can be restricted to the top of the welding machine body 1.
