Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 2-4, the present invention provides a technical solution: the utility model provides an automobile body hinge finish milling tool, includes installation roof beam 3 and clamp plate 1, and installation roof beam 3 comprises two rectangle posts 31 and end cover support 32, and two relative concatenations in rectangle post 31 position are a whole, and is formed with the square hole that the axial runs through at the middle part, and two end cover support 32 are fixed mounting respectively at the both ends of rectangle post 31, rotate between two end cover support 32 and are connected with the pivot 4 that runs through, and pivot 4 runs through and outer end fixed mounting has the rocking handle from the middle part in square hole.

Be equipped with the baffle 2 that a plurality of equidistant was arranged on clamp plate 1, the upper and lower both sides of installation roof beam 3 are equipped with the mounting groove that a plurality of equidistant was arranged, the upper end and the mounting groove phase-match joint of baffle 2, be formed with between two adjacent baffles 2 and press from both sides tight groove 5, the both sides of baffle 2 are equipped with the arch 10 with the work piece profile modeling, arch 10 is used for the location hinge when the clamping, it has the rubber pad to paste in one side of rectangle post 31 in the tight groove 5 of clamp, insert tight groove 5 of clamp with the hinge during the clamping, the bottom surface of hinge minor face exposes in order to wait to process in the outside.
