Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drill bits, in particular to a drill bit with adaptive deburring function. Background Art
[0002] During the processing of automobile aluminum alloy wheel hub holes, burrs may occur due to the characteristics of aluminum alloy. Traditionally, manual grinding and trimming are usually required to remove burrs. This method not only wastes labor costs, but also increases the difficulty of self-inspection. Utility Model Content
[0003] In view of the above technical problems, the utility model proposes a drill bit with adaptive deburring, comprising a cutter body, a cavity is arranged in the cutter body, a spring is fixedly installed inside the cavity, a rotating shaft is rotatably installed in the middle of the cavity, a rotating sheet body is fixedly installed on the rotating shaft, a steel ball for guiding is installed between the spring and the rotating sheet body, the extrusion force exerted on the rotating sheet body is transmitted to the spring through the steel ball, and a drill tip is detachably installed on the end of the cutter body away from the spring through a thread.
[0004] Furthermore, a notch is formed on one side of the cavity, and a portion of the rotating sheet body extends beyond the notch.
[0005] Furthermore, one end of the steel ball contacts the spring, and the other end of the steel ball contacts the rotating sheet.
[0006] Furthermore, the size of the steel ball matches the size of the cavity.
[0007] Furthermore, one end of the cutter body close to the spring is installed in the machine tool through a drill clamp.
[0008] Furthermore, the shape of the rotating sheet is irregular.
[0009] Furthermore, an escape space for the rotating sheet body to rotate is provided between the rotating sheet body and the cavity.
[0010] Compared with the prior art, the present invention has the following beneficial effects: (1) When the rotating sheet body in the present invention encounters sharp corners or burrs at the processed hole during processing, an extrusion force will be generated. The rotating sheet body transmits the extrusion force to the spring through the steel ball. The spring is compressed and the rotating sheet body rotates in the cavity through the rotating shaft. At the same time, the machine tool drives the entire body to rotate through the drill clamp, so that the rotating sheet body has the function of circumferentially scraping burrs, thereby effectively removing burrs at the processed hole; (2) The present invention is low in cost and easy to mass produce. It can replace manual removal of burrs in difficult structures and has broad application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.
[0016] Example: Figure 1-Figure 3 The drill bit with adaptive deburring shown in the figure comprises a cutter body 1, a cavity is arranged in the cutter body 1, a spring 2 is fixedly installed inside the cavity, a rotating shaft 4 is rotatably installed in the middle of the cavity, a rotating sheet 5 is fixedly installed on the rotating shaft 4, a steel ball 3 for guiding is arranged between the spring 2 and the rotating sheet 5, the extrusion force exerted on the rotating sheet 5 is transmitted to the spring 2 through the steel ball 3, a drill tip 6 is detachably installed at one end of the cutter body 1 away from the spring 2 through a thread; a notch is opened on one side of the cavity, and a part of the rotating sheet 5 exceeds the notch; one end of the steel ball 3 contacts with the spring 2, and the other end of the steel ball 3 contacts with the rotating sheet 5; the size of the steel ball 3 matches the size of the cavity; the end of the cutter body 1 close to the spring 2 is installed in the machine tool through a drill clamp; the shape of the rotating sheet 5 is irregular; an avoidance space for the rotation of the rotating sheet 5 is arranged between the rotating sheet 5 and the cavity.
[0017] The working principle of the utility model is as follows: the drill tip 6 is connected to the end of the cutter body 1 away from the spring 2 through a thread, and the end of the cutter body 1 close to the spring 2 is installed in the machine tool through a drill clamp. During processing, the drill tip 6 acts on the processed surface and performs chip removal processing in the axial direction. When the rotating sheet body 5 encounters sharp corners and burrs at the processed hole, an extrusion force will be generated. The rotating sheet body 5 transmits the extrusion force to the spring 2 through the steel ball 3. The spring 2 is compressed, and the rotating sheet body 5 rotates in the cavity through the rotating shaft 4. At the same time, because the machine tool drives the overall rotation through the drill clamp, the rotating sheet body 5 has the function of circumferentially scraping burrs, thereby effectively removing the burrs at the processed hole. After the burr removal is completed, the spring 2 drives the steel ball 3 and the rotating sheet body 5 to reset through elastic force.
