[0027] Please refer to the Figure 1 of the accompanying drawings of the specification. An embodiment of the present application provides an automobile part positioning tooling, including a mounting bracket 1. The mounting bracket 1 includes a collection groove 11. The collection groove 11 can be fixedly installed on a boring machine by cooperating with screws or bolts and nuts. A fixed rod 12 is detachably installed in the collection groove 11. The fixed rod 12 is vertically placed. One end of the fixed rod 12 in the length direction away from the bottom surface of the collection groove 11 is detachably connected to a fixed block 2, so that the position of the part 3 relative to the collection groove 11 is fixed. Among them, the fixed block 2 protrudes from the collection groove 11, and the part 3 also protrudes from the collection groove 11, preventing the vertical side wall of the collection groove 11 from interfering with the boring process of the vertical side wall of the part 3. And the fixed block 2 is located above the center position of the collection groove 11, so that the machining debris during the boring process can enter the collection groove 11 for collection. After the boring is completed, it is more convenient to clean the collection groove 11.

[0028] Please refer to the Figure 1 and Figure 2, the fixing block 2 is formed with four positioning blocks 21, and four positioning holes 31 are formed in the inner wall of the part 3. The four positioning holes 31 are used for the four positioning blocks 21 to be inserted into one by one correspondingly, so that the position of the part 3 is fixed relative to the fixing block 2. Two electric push rods 5 are detachably installed on the inner bottom surface of the collecting groove 11. The telescopic ends of the electric push rods 5 can contact the upper surface of the outer wall of the part 3 to further fix the position of the part 3. This design can prevent the electric push rods 5 from interfering with the boring operation of the vertical side wall of the part 3. The wall of the rear door hinge cover plate is relatively thin, and the depth of the positioning hole 31 is relatively shallow. By further restricting the displacement of the part 3 in the vertical direction through the electric push rods 5, the possibility of the part 3 shifting during the processing is reduced, ensuring the processing quality of the part 3.

[0029] Please refer to the Figure 1 , a fixing sleeve 15 is fixedly installed on the outer wall of the collecting groove 11, and a blowing pipe 4 is fixedly installed on the fixing sleeve. The blowing pipe 4 can be externally connected to an air pump to send cold air to the boring position of the part 3, thereby cooling the cutting tool for boring and extending the service life of the cutting tool. The blowing pipe 4 is located beside the boring position of the part 3 to avoid the blowing pipe 4 interfering with the boring of the cutting tool. At the same time, the cold air can timely blow away the machining debris generated during the boring process, and the machining debris can fall into the collecting groove 11 for collection, reducing the influence of the machining debris on the cutting tool.

[0030] Please refer to the Figure 1 , a sliding groove 111 is formed at one end of each of the three vertical side walls of the collecting groove 11 away from the ground. The three sliding grooves 111 are all slidably connected with a baffle 6. The baffle 6 is vertically placed, and a slider 61 is formed at the bottom of the baffle 6 along its own length direction. The slider 61 can be slidably connected with the sliding groove 111. The baffle 6 can reduce the possibility of the blown debris flying outside the collecting groove 11. An inclined surface 112 is formed on the inner bottom surface of the collecting groove 11, and a taking-out hole 113 is formed in the vertical side wall of the collecting groove 11. The taking-out hole 113 is located at one end of the inclined surface 112 close to the ground. A cover plate 10 is hinged to the collecting groove 11, and the cover plate 10 is detachably connected to the outer wall of the collecting groove 11 so that the cover plate 10 seals the taking-out hole 113. A magnet 13 is embedded on the outer wall of the collecting groove 11, and a magnet 14 is embedded on the cover plate 10. The magnet 13 and the magnet 14 can attract each other, and at this time, the cover plate 10 can seal the taking-out hole 113. A handle is installed on the cover plate 10, and the handle makes it more convenient for people to open the cover plate.

[0031] Working principle of this embodiment: When boring the hole of part 3, first, the four positioning blocks 21 are respectively and correspondingly clamped into the four positioning holes 31. Then, the two electric push rods 5 are activated so that the telescopic ends of the two electric push rods 5 are both in contact with the upper surface of part 3. At this time, the position of part 3 can be fixed relative to the position of the collection groove 11. During the boring process, the air blowing pipe 4 can send cold air to the machining surface of part 3, and at the same time, the machining debris of part 3 can be blown away. The machining debris can fall into the collection groove 11 for collection, which is relatively convenient.

[0032] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
