[0002] The domestic EGR cooler core is generally a shell-and-tube structure, such as figure 1 , figure 2 As shown, one end of several radiating pipes 1 is installed on the mounting hole of flange 2, and the several radiating pipes 1 are divided into two groups, and the core body of the EGR cooler also includes a support plate 3 for supporting the radiating pipes 1, The support plate 3 has mounting holes for the heat pipe 1 to pass through, and the support plate 3 is usually provided with 3 groups. At present, it is usually assembled by hand in China. Since the core structure of this round tube type EGR cooler is relatively complicated, The assembly gap between the heat pipe 1 and the installation holes of the flange 2 and the support plate 3 is relatively small, so the assembly efficiency is low during manual assembly, and the assembly quality is not uniform

Embodiment Construction
[0033] Example to assemble as figure 1 , figure 2 The shown EGR cooler core is taken as an example to describe the technical scheme of the present invention in detail. One end of the 38 heat dissipation pipes 1 is installed on the flange 2, and the 38 heat dissipation pipes 1 are divided into two groups, and the heat dissipation pipes 1 pass through the flange. 2 and 3 sets of mounting holes for the support plate 3 , the support plate 3 supports the cooling pipe 1 .
[0034] Such as Figure 3 to Figure 6 As shown, the EGR cooler core assembly machine includes a frame 4, and a fixing device and a propulsion device are arranged on the frame 4. The fixing device is used to fix the flange 2 and the support plate 3 of the EGR cooler core, and push The device is used to assemble the heat pipe 1 onto the flange 2 and the support plate 3 .
[0035] The fixing device includes two guide posts 7 and a support 5 arranged on the working platform of the frame 4, the support 5 is arrange...

The invention relates to an assembling machine, comprising a frame and a propulsion device, wherein the frame is provided with a fixing device for fixing a flange and a supporting plate, and the propulsion device is used for assembling a heat dissipation pipe on the flange and the supporting plate. After the flange and the supporting plate are fixed, the heat dissipation pipe can be pushed forwards in parallel along a guide groove, and under the action of a push plate and a protrusion, the heat dissipation pipe passes through the supporting plate and the flange to reach a position limited by a positioning plate so as to complete the assembling of the core of an EGR cooler. The assembling quality is stable and reliable and the efficiency is high.
Description
technical field [0001] The invention relates to an EGR cooler core assembly machine, which belongs to the technical field of machinery. Background technique [0002] The domestic EGR cooler core is generally a shell-and-tube structure, such as figure 1 , figure 2 As shown, one end of several heat dissipation pipes 1 is installed on the installation hole of flange 2, and the several heat dissipation pipes 1 are divided into two groups, and the EGR cooler core also includes a support plate 3 for supporting heat dissipation pipes 1 The support plate 3 has mounting holes for the passage of the radiating pipe 1, and the support plate 3 is usually provided with 3 groups. At present, it is usually assembled by hand in China. Since the core structure of this round tube type EGR cooler is relatively complicated, The assembly gap between the heat pipe 1 and the mounting holes of the flange 2 and the support plate 3 is relatively small, therefore, the assembly efficiency during manu...
