Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a double-track welding device for an intercooler. Background Art

[0002] For a supercharged engine, an intercooler is an important component of the supercharging system. Whether it is a mechanically supercharged engine or a turbocharged engine, an intercooler needs to be installed between the supercharger and the engine intake pipe. The intercooler plays a role in cooling the air. The high-temperature air is cooled by the intercooler and then enters the engine. If the supercharged high-temperature air directly enters the engine without an intercooler, the engine may be damaged or even stall due to the too high air temperature. To solve the adverse effects caused by the temperature rise of the supercharged air, an intercooler needs to be installed to reduce the intake air temperature. The intercooler core is welded to the main air chamber plate.

Detailed implementation manners

[0026] Embodiment 1

[0027] As Figures 1-3 shown, a double-track welding device for an intercooler proposed in this embodiment includes a frame 1, a conveyor belt 2, a brown glass cover 3, a gas purification mechanism, two welding equipments 18, a plurality of automatic clamping mechanisms and a plurality of lifting mechanisms.

[0028] A bracket 4 is arranged on the frame 1; a power assembly for driving the movement of the conveyor belt 2 is installed on the frame 1. The power assembly includes a servo motor 21 and two drive rollers 12. The two drive rollers 12 are respectively rotatably installed at both ends of the frame 1. The length of the drive roller 12 is less than the width of the conveyor belt 2. Such a setting enables the connecting frame 8 to move smoothly and avoids blocking the movement of the connecting frame 8. The conveyor belt 2 is sleeved and installed on the two drive rollers 12. The servo motor 21 is installed on the frame 1 and its output shaft is connected to the rotating shaft of the drive roller 12. Starting the servo motor 21 to work can drive the drive roller 12 to rotate, and then drive the conveyor belt 2 to move.

[0029] The brown glass cover 3 is slidably arranged on the bracket 4 in the vertical direction. The brown glass cover 3 is located above the conveyor belt 2. A guide rod b14 is connected to the brown glass cover 3 and penetrates through the top end of the bracket 4 movably. A limit block 15 is arranged at the top end of the guide rod b14. The arrangement of the limit block 15 can prevent the brown glass cover 3 from contacting the surface of the conveyor belt 2, so that there is a small gap between the brown glass cover 3 and the conveyor belt 2 to avoid friction. Guide plates b17 are arranged on both sides of the inner wall of the brown glass cover 3. One end of the guide plate b17 is provided with a chamfer. When the hemispherical block 11 contacts the chamfer on the guide plate b17, it forces the guide rod 9 to move to one side, that is, drives the clamping frame 5 to move, thereby realizing the clamping work of the intercooler. Lifting blocks 13 are connected to the four corner positions at the bottom end of the brown glass cover 3.

[0030] Two welding devices 18 are installed side by side on the inner wall of the brown glass cover 3.

[0031] The automatic clamping mechanism includes two groups of elastic clamping components arranged symmetrically. The elastic clamping component includes a clamping frame 5, a connecting frame 8, a guide rod 9, a spring 10 and a hemispherical block 11. The connecting frame 8 is fixed on the conveyor belt 2. The guide rod 9 penetrates through the connecting frame 8 movably. The two ends are respectively connected to the clamping frame 5 and the hemispherical block 11. The spring 10 is sleeved on the guide rod 9.

[0032] Multiple lifting mechanisms correspond to multiple automatic clamping mechanisms one by one. The lifting mechanism includes two groups of lifting components arranged symmetrically. The lifting component includes a guide plate a6 and a wedge block 7. The guide plate a6 is connected to the connecting frame 8. The wedge block 7 is arranged at the end of the guide plate a6.

[0033] The gas purification mechanism is installed on the bracket 4 for filtering the air inside the brown glass cover 3. The gas purification mechanism includes a suction nozzle 19, an air pump and a gas treatment box 20. The suction nozzle 19 is installed on the top wall of the brown glass cover 3. The gas treatment box 20 is installed on the bracket 4. The air pump is arranged inside the gas treatment box 20. A hose is connected between the input end of the air pump and the suction nozzle 19. An exhaust pipe is communicated with the gas treatment box 20. A filter is installed in the exhaust pipe. A ventilation pipe is communicated with the brown glass cover 3. A one-way valve is installed on the ventilation pipe. During the air extraction process, the outside gas enters the inside of the brown glass cover 3 through the ventilation pipe, and the set one-way valve only allows the outside gas to flow in one direction.

[0034] When performing welding work on the intercooler, place the intercooler between two clamping brackets 5. The clamping bracket 5 is of a "U" - shaped structure. The power assembly is set to drive the movement of the conveyor belt 2, that is, to drive the automatic clamping mechanism to move. When the wedge - shaped block 7 contacts the left - hand lifting block 13, it forces the lifting block 13 to gradually move upward, thereby driving the tea - colored glass cover 3 to move. Subsequently, when the guide plate a6 contacts the lifting block 13, the tea - colored glass cover 3 rises to the defined height position. When the guide plate a6 separates from the lifting block 13, the tea - colored glass cover 3 drops. At this time, there is a gap between the bottom end of the tea - colored glass cover 3 and the conveyor belt 2, which can prevent large friction from occurring between the conveyor belt 2 and the tea - colored glass cover 3. The intercooler is placed inside the tea - colored glass cover 3. When the hemispherical block 11 contacts the chamfer at the end of the guide plate b17, it forces the guide rod 9 to move, that is, to drive the clamping bracket 5 to move, making the two clamping brackets 5 approach each other, thus realizing the clamping and fixing work of the intercooler. After the intercooler is clamped, the two welding devices 18 installed can realize the synchronous welding work on both sides of the intercooler, improving the welding work efficiency. The setting of the tea - colored glass cover 3 can prevent the dust generated during the welding process from spreading into the air, avoiding pollution to the working environment. At the same time, it can also prevent the sparks from splashing during welding, improving the construction safety. During the welding process, the air pump can be started to pump out the dust and gas inside the tea - colored glass cover 3. The gas is purified and filtered through the filter. When the hemispherical block 11 separates from the guide plate b17, under the elastic force of the spring 10, the clamping bracket 5 is driven to reset, that is, the fixing work of the intercooler is released. When the wedge - shaped block 7 contacts the right - hand lifting block 13, it pushes the tea - colored glass cover 3 upward again, enabling the intercooler to smoothly move out from the inside of the tea - colored glass cover 3.

Compared with Embodiment 1, in this embodiment, a support plate 16 is arranged inside the conveyor belt 2, and the support plate 16 is connected to the bracket 4. By setting the support plate 16, the phenomenon that the upper end of the conveyor belt 2 sags can be prevented.

However, the present utility model is not limited to this. Within the scope of knowledge possessed by those skilled in the art to which it pertains, various changes can be made without departing from the gist of the present utility model.
