DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments, but it should not be understood that the scope of the subject matter described in the present invention is limited to the following embodiments. Without departing from the above-mentioned technical ideas of the present invention, various modifications, substitutions and changes made according to the common technical knowledge and customary means in the field are included in the scope of the present invention.

[0021] like Figures 1-2 As shown, the design scheme of the manual assembly tooling of the radiator core assembly in the utility model includes a first positioning block 1, a second positioning block 2, a mounting plate 3, a positioning plate 4, a pad 5, a quick clamp 6 and a leveling plate 7.

[0022] like Figure 2The mounting plate 3 is used as the reference and mounting plane of the whole set of tooling, and the pad 5 is installed on the upper end surface of the mounting plate 3 as a part for adjusting the height of the tooling. The positioning plate 4 is installed on the upper end surface of the pad 5. The upper end surface of the positioning plate 4 is provided with two positioning protrusions for matching the first channel steel 12 and the second channel steel 13, one of which is close to the left end of the positioning plate 4 in the length direction, and the other is close to the right end of the positioning plate 4 in the length direction. The positioning protrusions have two functions, one is to facilitate the positioning of the first channel steel 12 and the second channel steel 13, and the other is to raise the height of the first channel steel 12 and the second channel steel 13 to be consistent with the axis of the radiator core assembly, so as to facilitate the subsequent brazing fixture clamping and prevent deformation. The first positioning block 1 and the second positioning block 2 are both located on the upper end surface of the pad 5, and the first positioning block 1 is close to the left end surface of the positioning plate 4 in the length direction. The first positioning block 1 is provided with a positioning groove for the oil pipe 9, and the second positioning block 2 is close to the rear end surface of the positioning plate 4 in the width direction. The upper end surface of the first positioning block 1 and the upper end surface of the second positioning block 2 are both located above the upper end surface of the positioning plate 4, so that the assembly space of the radiator core assembly is formed between the first positioning block 1, the second positioning block 2 and the positioning plate 4. The quick clamp 6 is arranged on the upper end surface of the mounting plate 3 and away from the second end in the length direction of the positioning plate 4. The clamp head of the quick clamp 6 is located above the upper end surface of the positioning plate 4, and the movement direction of the clamp head is parallel to the length direction of the positioning plate 4. The leveling plate 7 is used to close the upper end of the aforementioned assembly space from top to bottom. The lower end surface of the leveling plate 7 is a plane, and a handle is arranged on the upper end of the leveling plate 7 for easy operation. The first positioning block 1, the second positioning block 2, the positioning plate 4 and the mounting plate 3 are connected by screws and positioning pins.

[0023] The assembly process using the above-mentioned manual assembly tooling is as follows:

[0024] (1) Arrange the rib sheet 8, the oil inlet and outlet pipes 9, the first mounting plate 10, the second mounting plate 11, the first channel steel 12 and the second channel steel 13 according to the Figure 3 The position relationship is placed on the upper end face of the positioning plate 4 of the assembly tool (two stainless steel pipes are used to pass through the pipe openings of the inlet and outlet oil pipes 9, the ribs 8, the first mounting plate 10 and the openings on the second mounting plate 11 to simply connect the four), a first channel steel 12 is placed on one side of the first mounting plate 10, and the clamp head of the quick clamp 6 is facing the first channel steel 12. One side end faces of multiple ribs 8 pass through the first channel steel 12 and are close to the end face of the second positioning block 2. The inlet and outlet oil pipes 9 are placed in the positioning notch of the first positioning block 1 to avoid interference. The first channel steel 12 and the second channel steel 13 are placed on two positioning protrusions on the positioning plate 4, so that their height is raised to the same height as the axis of the radiator core assembly (on the same horizontal plane), wherein one side end face of the second channel steel 13 is just in close contact with the end face of the pipe opening of the inlet and outlet oil pipes 9, so that the second mounting plate 11 is pressed against the ribs 8 through the inlet and outlet oil pipes 9, and the other side end face of the second channel steel 13 is in close contact with the end face of the first positioning block 1;

[0025] (2) Use the leveling plate 7 to flatten the rib sheet 8, the first mounting plate 10, and the second mounting plate 11 from top to bottom to ensure that the parts are flush;

[0026] (3) Push the handle of the quick-action clamp 6 to drive the clamp head to move toward the radiator core assembly until the first channel steel 12 is pressed tightly, and the rib sheet 8, the first mounting plate 10, the second mounting plate 11 and the inlet and outlet oil pipes 9 are pressed tightly together;

[0027] (4) Clamp the brazing fixture on the first channel steel 12 and the second channel steel 13 in the circumferential direction of the radiator core assembly and apply a clamping force;

[0028] (5) Pull the quick-action clamp 6 away from the radiator core assembly, remove the brazing fixture and radiator core assembly that have been fixed together, and put the whole into a brazing furnace for brazing.

[0029] The manual assembly tool of the utility model is mainly made of plate parts, and the processing accuracy of each component is high, so as to ensure the final assembly accuracy of the radiator core assembly. The components are connected by screws and cylindrical pins to ensure that there is no movement between the components (first positioning block 1, second positioning block 2, mounting plate 3, positioning plate 4, pad 5), accurate positioning, reliable positioning, and thus ensure the assembly accuracy of the radiator core assembly.

[0030] The above is the main concept of the utility model, and all manual assembly tools designed based on the concept of the utility model fall within the protection scope of the utility model.
