[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] like Figure 3 As shown, a fixing device for processing an EGR cooler bracket includes a support plate 1, two side positioning modules, a positioning pin 2 and a bottom support rod 3.

[0039] The support plate 1 is an elongated structure with connection holes 4 at both ends. The support plate 1 is fixed to the rotating table through the connection holes 4 at its ends. A hollow area 5 is provided on the support plate 1 corresponding to the back surface of the EGR cooling bracket to be processed.

[0040] Two side positioning modules are provided on the upper surface of the support plate 1 and located on the same side of the support plate 1. The two side positioning modules are aligned along the length of the support plate 1. The side positioning modules include a vertical plate 6, a horizontal plate 7, and a first bolt 8. The top center of the vertical plate 6 is recessed downward to form a recessed area 9. The inner end of the vertical plate 6 is higher than the outer end of the vertical plate 6. The horizontal plate 7 is fixed to the outer side of the vertical plate 6 along the length of the support plate 1. The first bolt 8 is horizontally threaded on the horizontal plate 7 along the width of the support plate 1 and penetrates the inner and outer sides of the horizontal plate 7. In this embodiment, each first bolt 8 is sleeved with a first nut 10 to prevent the first bolt from loosening.

[0041] The positioning pin 2 is fixed on the support plate 1 , and the position of the positioning pin 2 on the support plate 1 is adapted to the EGR cooling bracket to be processed.

[0042] The number of the bottom support plates 3 is at least two, and the top of the bottom support plates 3 is a horizontal plane. The height of the bottom support plates 3 is adapted to the EGR cooling bracket to be machined. In this embodiment, the number of the bottom support plates 3 is two.

[0043] When fixing the EGR cooling bracket, first insert the corresponding position of the bottom of the EGR cooling bracket to be processed into the positioning pin 2, and then slowly rotate the EGR cooling bracket around the positioning pin 2 so that one side of the EGR cooling bracket is clamped in the two recessed areas 9, press the EGR cooling bracket downward so that its bottom is in contact with the top of the bottom support rod 3, ensure that the EGR cooling bracket is horizontal, tighten the two first bolts 8, and make the inner side of the EGR cooling bracket close to the inward side wall of the recessed area 9, and then fix the support plate 1 on the external rotating table, and the tool on the rotating table processes the front of the EGR cooling bracket, and then the rotating table drives the support plate to flip, and the tool passes through the hollow area 5 on the support plate 1 to turn the back of the EGR cooling bracket.

[0044] In this embodiment, if Figure 4 As shown, the support plate 1 is provided with a top pressing module, and the number of the top pressing modules is at least two; the top pressing module includes a screw 11, a pressing block 12, and a second nut 13; the screw 11 is vertically fixed to the support plate 1; the pressing block 12 is slidably sleeved on the screw 11; the second nut 13 is threadedly connected to the screw 11 and is located above the pressing block 12; after the EGR cooling bracket is positioned, the second nut 13 is screwed so that the pressing block 12 presses the top of the EGR cooling bracket to prevent the EGR cooling bracket from shaking during machining and affecting the machining accuracy. Furthermore, in this embodiment, the number of the top pressing modules is two.

[0045] In this embodiment, if Figure 4 As shown, the support plate 1 is also equipped with an end positioning module, which is located on the end of the support plate 1 away from the positioning pin 2. The end positioning module includes a fixing seat 14 and a second bolt 15. The second bolt 15 is arranged on the fixing seat 14 along the length of the support plate 1 and points to the other end of the support plate 1. This arrangement can cooperate with the positioning pin 2 to fix the EGR cooling bracket along the length of the support plate, further ensuring its processing accuracy. Furthermore, a third nut 16 is sleeved on the second bolt 15 to effectively prevent the second bolt 15 from loosening.
