[0033] Example: Figure 1-3 As shown, a ceiling upper beam processing tool includes two tool modes;

[0034] Tooling 1: The base plate 1 is connected to the support base 3 through the first bolt 2, and the support base 3 is connected to the machine tool processing platform through the second bolt 4. A clamp column 5 is welded to the left side of the upper end surface of the base plate 1, and a first clamp 6 is connected to the top of the clamp column 5 through a T-slot. A clamp column 5 is also welded to the right side of the upper end surface of the base plate 1, and a second clamp 7 is connected to the top of the clamp column 5 through a T-slot. A curved support template 8 is set in the middle position of the upper end surface of the base plate 1, and the curved support template 8 is fixed to the base plate 1 by screws 9.

[0035] Tooling 2: Connect the base plate 1 to the support base 3 through the first bolt 2, and the support base 3 is connected to the machine tool processing platform through the second bolt 4. A clamping column 5 is welded to the left side of the upper end surface of the base plate 1, and a clamping column 5 is also welded to the right side of the upper end surface of the base plate 1. A pressing plate 11 is connected above the clamping column 5 through a T-slot using a third bolt 10. The pressing plate 11 can ensure that the profile 13 is stably and firmly clamped when processing the upper side beam profile 13 at the passenger compartment door. A curved support template 8 is set in the middle position of the upper end surface of the base plate 1, and the curved support template 8 is fixed to the base plate 1 by screws 9.

[0036] The curved support templates 8 on the above two types of tooling are of the same structure, and both include a support body 8-1, a positioning plate 8-2 and a limit plate 8-3. The positioning plate 8-2 is arranged on the left side of the support body 8-1, and the limit plate 8-3 is arranged on the right side of the support body 8-1. The height of the positioning plate 8-2 is not less than the height of the limit plate 8-3. The support body 8-1, the positioning plate 8-2 and the limit plate 8-3 are an integrated structure.

[0037] A support groove 12 is formed between the support body 8-1, the positioning plate 8-2 and the limiting plate 8-3, and the upper side beam profile 13 to be processed is placed in the support groove 12, and the contact surfaces on the positioning plate 8-2 and the limiting plate 8-3 with the upper side beam profile 13 to be processed are both set to external inclined surfaces, which is conducive to the lifting and removal of the upper side beam profile 13, and the internal shape of the support groove 12 is consistent with the outer contour of the upper side beam profile 13 to be processed, that is, the outer contour of the upper side beam profile 13 is accurately fitted in the support groove 12, so the curved support template 8 can also be used to detect whether the outer curvature of the upper side beam profile 13 is out of tolerance.

[0038] During operation, a tool 1 is placed on both sides of each passenger compartment door on the upper side beam profile 13, and a tool 2 is placed at the center position of each passenger compartment door on the upper side beam profile 13. The upper side beam profile 13 to be processed is placed in the corresponding curved support templates 8 on the tool 1 and the tool 2, and the first clamping device 6 on the tool 1 is used to clamp the corresponding upper slide groove 14 on the upper side beam profile 13, and the second clamping device 7 on the tool 1 is used to clamp the corresponding lower slide groove 15 on the upper side beam profile 13, and the pressing plate 11 on the tool 2 is used to clamp the corresponding lower slide groove 15 on the upper side beam profile 13. The clamping positions of the first clamping device 6 and the second clamping device 7 avoid the positions where the upper slide groove 14 and the lower slide groove 15 on the upper side beam profile 13 need to be processed. Then, the upper side beam profile 13 is processed by a machine tool. When the machine tool processes the lower slide groove 15, the profile under the pressing plate 11 will be completely cut off. After cutting off, the pressing plate 11 loses its function and the machining is completed.
