[0042] Example

[0043] like Figure 1-4 As shown, the present invention provides a technical solution: an EGR housing assembly mechanism, comprising an equipment platform 1, a positioning tool 2, an end cover housing tool 3, an end cover tool 4 and a housing transverse movement mechanism 5 are installed on the top of the equipment platform 1, the positioning tool 2 is located at the center of the top of the equipment platform 1, the end cover housing tool 3 and the end cover tool 4 are respectively located on both sides of the positioning tool 2, the housing transverse movement mechanism 5 is located on the back and above the positioning tool 2, the end cover tool 4 and the housing transverse movement mechanism 5 are driven by a screw drive mechanism 6 to be laterally located close to / away from the positioning tool 2, and a control panel 8 is installed on the front of the equipment platform 1;

[0044] The positioning fixture 2 includes a first comb tooth positioning block 21, a second comb tooth positioning block 22, a positioning block lifting cylinder 23, a flat tube clamping cylinder 24 and a clamping piece 25. The first comb tooth positioning block 21 is close to the end cover housing fixture 3, and the second comb tooth positioning block 22 is close to the end cover fixture 4. The positioning block lifting cylinder 23 is provided with two cylinders respectively installed at the bottom of the first comb tooth positioning block 21 and the second comb tooth positioning block 22. The flat tube clamping cylinder 24 is provided with four cylinders symmetrically arranged on the front and rear sides of the first comb tooth positioning block 21, and the output end is provided with the clamping piece 25 facing the first comb tooth positioning block 21;

[0045] The end cover shell tooling 3 includes a support plate a31, a flat tube guide strip a32, and a shell straightening cylinder 33. The flat tube guide strip a32 is installed on the support plate a31, and the shell straightening cylinder 33 is installed below the flat tube guide strip a32. The output end faces the flat tube guide strip a32 and is installed with a straightening seat 34; the end cover tooling 4 includes a support plate b41 and a flat tube guide strip b42. The flat tube guide strip b42 is installed on the support plate b41. The shell straightening cylinder 33 works and rises to drive the straightening seat 34 to resist the shell for straightening, thereby ensuring the stability and correctness of the shell during the assembly process.

[0046] It should be added that the flat tube guide strip a32 and the flat tube guide strip b42 are smaller than the flat tube, and the flat tube guide strip a32 and the flat tube guide strip b42 are provided with guide protrusions toward the ends of the flat tube for contacting the inside of the flat tube, and the flat tube guide strip a32 and the flat tube guide strip b42 are respectively connected to the left end cover and the right end cover, and a shell is sleeved on the periphery of the flat tube guide strip a32.

[0047] The shell transverse movement mechanism 5 includes a support frame 51, a front and rear telescopic cylinder 52, a displacement plate 53, a guide rail 54, a slider 55, a left and right transverse movement cylinder 56, a lifting cylinder 57 and a clamping cylinder 58. The front and rear telescopic cylinders 52 have two groups installed on both sides of the front side of the support frame 51 near the top, and the output ends of the front and rear telescopic cylinders 52 face the top of the positioning tooling 2 and are installed with a displacement plate 53. The guide rail 54 is installed on the displacement plate 53 and arranged horizontally. The slider 55 is slidably connected to the guide rail 54. The left and right transverse movement cylinder 56 installed on one side of the displacement plate 53 is extended and retracted, thereby making the slider 55 slide horizontally on the guide rail 54. The lifting cylinder 57 is installed on the slider 55 with the output end facing the bottom. The clamping cylinder 58 is installed at the bottom of the lifting cylinder 57. The shell transverse movement mechanism 5 realizes multi-axis motion control through the front and rear telescopic cylinder 52, the left and right transverse movement cylinder 56 and the lifting cylinder 57, and can flexibly move the shell to a specified position.

[0048] Embodiment 2, as Figure 1-7 As shown, the first comb tooth positioning block 21 and the second comb tooth positioning block 22 are both provided with a spacing groove 26 separated by comb teeth, and the spacing grooves on the first comb tooth positioning block 21 and the second comb tooth positioning block 22 correspond to each other, the comb teeth on the first comb tooth positioning block 21 are arranged on the side close to the end cover shell tooling 3, the spacing groove 26 of the first comb tooth positioning block 21 is used for placing flat tubes, and connecting pieces are placed between the flat tubes.

[0049] The above embodiment needs to be further supplemented that, Figure 2 As described above, the number of the flat tube guide strips a32 and the flat tube guide strips b42 is the same as the number of the spacing grooves 26, and the second comb tooth positioning block 22 and the first comb tooth positioning block 21 also play a role in guiding the flat tube guide strips a32 and the flat tube guide strips b42 to contact the flat tube into the flat tube.

[0050] like Figure 3 As mentioned above, a pressure sensor 28 is installed on the first comb-tooth positioning block 21 to detect the overall weight of the flat tube and the connecting piece to avoid the possibility of missing parts.

[0051] like Figure 4 and Figure 5 The screw drive mechanism 6 is provided with two groups, including an upper screw drive mechanism 6 and a lower screw drive mechanism 6. The lower screw drive mechanism 6 drives the upper screw drive mechanism 6 to approach the positioning tooling 2, and the upper screw drive mechanism 6 drives the support plate a31 and the support plate b41 to drive the flat tube guide strip a32 and the flat tube guide strip b42 to contact the flat tube located above the first comb tooth positioning block 21.

[0052] Among them, the upper screw drive mechanism 6 and the lower screw drive mechanism 6 are both composed of a drive motor, a screw and a slide rail. The upper screw drive mechanism 6 and the lower screw drive mechanism 6 are connected by a connecting plate 7, and the upper screw drive mechanism 6 and the support plate a31 and the support plate b41 are connected by a connecting plate 7.

[0053] The flat tube clamping cylinder 24 is installed on the bottom bracket 27, and the length of the clamping member 25 is the same as the lifting height of the positioning block lifting cylinder 23 driving the first comb tooth positioning block 21, so that the clamping member can clamp flat tubes of different heights through the extension and contraction of the flat tube clamping cylinder 24.

[0054] like Figure 7 As described above, the EGR is composed of a shell, a flat tube, a connecting piece, and left and right end covers.

[0055] The working process of the present invention is as follows: various components (positioning tooling 2, end cover shell tooling 3, end cover tooling 4, shell transverse movement mechanism 5, etc.) on the equipment platform 1 are adjusted to the initial position to ensure that each component is in a ready-to-work state, and the flat tubes are placed one by one in the spacing grooves 26 of the first comb tooth positioning block 21, and connecting pieces are placed between the flat tubes. Since the spacing grooves on the first comb tooth positioning block 21 and the second comb tooth positioning block 22 correspond to each other, the flat tubes and the connecting pieces can be accurately aligned in the horizontal direction. The pressure sensor 28 on the first comb tooth positioning block 21 can detect the overall weight of the flat tubes and the connecting pieces in real time to ensure that the placed materials meet the requirements. At the same time, the left end cover and the right end cover are respectively connected to the flat tube guide strip a32 and the flat tube guide strip b42, and a shell is sleeved on the flat tube guide strip a32;

[0056] Start the flat tube clamping cylinder 24 so that its output end pushes the clamping piece 25 toward the first comb tooth positioning block 21 to clamp and fix the flat tube and the connecting piece. This can prevent the flat tube and the connecting piece from shifting during the subsequent assembly process. The end cover housing fixture 3 and the end cover fixture 4 are driven to approach the positioning fixture 2 through the screw drive mechanism 6 (lower screw drive mechanism 6). The upper screw drive mechanism 6 drives the support plate a31 and the support plate b41 to drive the flat tube guide strip a32 and the flat tube guide strip b42 to respectively contact the two ends of the flat tube located above the first comb tooth positioning block 21 and the second comb tooth positioning block 22. The convex block structures on the flat tube guide strip a32 and the flat tube guide strip b42 will contact the inside of the flat tube to ensure the stability of the flat tube during assembly. Qualitatively, start the front and rear telescopic cylinders 52 in the shell transverse movement mechanism 5 to move the displacement plate 53 toward the top of the positioning tooling 2, and the left and right transverse movement cylinders 56 drive the slider 55 to slide laterally on the guide rail 54, adjust the position of the clamping cylinder 58, and when the clamping cylinder 58 moves to the appropriate position, start the lifting cylinder 57 to lower it, and the clamping cylinder 58 grabs the shell, and at the same time, the left and right transverse movement cylinders 56 drive the slider 55 to slide laterally on the guide rail 54, so that the shell and the left end cover are moved to the periphery of the flat tube. At this time, the flat tube guide strips a32 and b42 are driven to extend to the inside of the flat tube by the screw drive mechanism 6 (upper screw drive mechanism 6), so that the end cover contacts the flat tube, and the shell and the flat tube and the connecting piece are assembled.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
