[0039] The working principle of the brass parts processing fixture for preventing deformation and scratching provided by the utility model is as follows:

[0040] Before the brass part needs to be processed, firstly, the bottom thread of the guide shaft 501 is connected to the locking screw hole 201, and then aligned with the through hole 101, the brass part 1 is set on the bottom jig 2, and the opening on the top jig 3 and the guide shaft 501 are aligned, and the top jig 3 is set on the brass part 1. At this time, the top of the guide shaft 501 passes through the through hole 101 and the top jig 3, so that the locking screw hole 201 and the through hole 101 are quickly aligned, and then the top jig 3 and the bottom jig 2 are fixed by the locking bolt 4. The top jig 3 and the bottom jig 2 position the brass part 1 in the middle. At this time, the top jig 3 contacts the brass part 1 through the second rubber protective pad 302, and the bottom jig 2 contacts the brass part 1 through the first rubber protective pad 202;

[0041] On the contrary, after the processing of the brass part 1 is completed, the locking bolt 4 is removed, and then the top jig 3 is moved upward, and the brass part 1 can be moved upward to remove the brass part 1.

[0042] Compared with the related art, the brass parts processing fixture for preventing deformation and scratching provided by the utility model has the following beneficial effects:

[0043] The utility model passes the brass part 1 and the bottom jig 2 through the guide shaft 501, so that the through hole on the brass part 1 can be quickly aligned with the locking screw hole 201 on the bottom jig 2, and then the top jig 3 and the bottom jig 2 are fixed to the top and bottom of the brass part 1 through the locking bolt 4, so as to position the brass part and ensure that the brass part 1 does not move during processing. At the same time, the first rubber protection pad 202 and the second rubber protection pad 302 are used as the contact surface between the jig and the brass part 1, so as to prevent the brass part 1 from being deformed by pressure or being scratched by hard objects on the surface.

[0044] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
