[0021] The following is combined with Figure 1-3 This application is described in further detail.

[0022] The present application embodiment discloses a drilling machine for processing automobile parts. Figure 1-3 A drilling machine for processing automobile parts, comprising a processing table 1, a gantry 2 is installed on the processing table 1, the gantry 2 is installed on the drilling machine 3, and is used to adjust the position of the drilling machine 3, a connecting ear 7 is installed on the side of the drilling machine 3, a threaded rod 601 passes through the connecting ear 7 and is slidably connected with the connecting ear 7, a drill bit 4 is installed at the output end of the drilling machine 3, and the drilling machine 3 drives the drill bit 4 to rotate to realize drilling processing, a cleaning component 5 is sleeved on the drill bit 4, and the cleaning component 5 includes a support ring 501 installed on the outside of the drill bit 4, a plurality of telescopic members 502 are installed on the inner side of the support ring 501, and a cleaning head 503 is installed on the telescopic member 502, and is used to clean the hanging residual material in the spiral groove on the drill bit 4, and a driving component 6 is installed on the connecting ear 7, and the driving component 6 includes a support frame 604 movably installed on the outside of the support ring 501, a threaded rod 601 is installed on the support frame 604, and a reset unit is sleeved on the threaded rod 601, and the reset unit includes a reset spring 603 installed between the connecting ear 7 and the support frame 604;

[0023] By adopting the above technical solution, when the drill bit 4 is rotating for drilling processing, the limit plate 6044 abuts against the automobile workpiece, and the workpiece can be preliminarily positioned, so that the support frame 604 compresses the reset spring 603, driving the support ring 501 to move up along the threaded groove on the drill bit 4, and at the same time, the support ring 501 rotates relative to the support frame 604 and the threaded rod 601. After the drilling is completed, when the drill bit 4 stops rotating and exits the drilling, the elastic force of the reset spring 603 is used to push the threaded rod 601 and the support frame 604 downward, thereby causing the support ring 501 to rotate and move downward, driving the cleaning head 503 to remove the drill bit residue along the threaded groove.

[0024] Reference Figure 3 The telescopic member 502 includes a sleeve 5021 installed in the support ring 501, a support rod 5022 connected to the cleaning head 503 is slidably installed in the sleeve 5021, and a support spring 5023 is installed between the support rod 5022 and the sleeve 5021. The elastic force of the support spring 5023 makes the cleaning head 503 abut against the drill bit 4, which can adapt to drill bits 4 of various specifications.

[0025] Reference Figure 2 The top thread of the threaded rod 601 is provided with a limiting nut 602, and the connecting ear 7 is located between the limiting nut 602 and the reset spring 603. By turning the limiting nut 602, the telescopic activity of the threaded rod 601 can be adjusted, which can be suitable for drill bits 4 of different lengths.

[0026] Reference Figure 3 The support frame 604 includes a connecting ring 6041 sleeved on the outside of the support ring 501, and a plurality of fixed columns 6042 are installed on the inner side of the connecting ring 6041. A sliding sleeve 6043 is sleeved on the fixed column 6042 and is in rolling contact with the support ring 501. Limiting plates 6044 are installed on both upper and lower ends of the fixed column 6042. The support ring 501 is slidably installed on the inner side of the limiting plate 6044. Two threaded rods 601 are fixedly connected to the corresponding fixed columns 6042. The supporting ring 501 can slide relative to the threaded rod 601 and the connecting ring 6041 through the sliding sleeve 6043. The supporting ring 501 is vertically limited by the limiting plate 6044, so that the supporting ring 501 can move up and down along the thread groove on the drill bit 4.

[0027] The implementation principle of the automobile parts processing drilling machine of the embodiment of the present application is as follows: during assembly, the threaded rod 601 is passed through the connecting ear 7, and the limiting nut 602 is screwed so that the cleaning head 503 is exactly located at the bottom end of the side of the drill bit 4. When the drill bit 4 is rotating and drilling, the gantry 2 drives the drill 3 and the drill bit 4 to move downward, and the drill 3 drives the drill bit 4 to rotate so that the limiting plate 6044 abuts against the automobile workpiece, so that the workpiece can be preliminarily positioned, and at the same time, the support frame 604 compresses the reset spring 603, driving the support ring 501 along the upper side of the drill bit 4. The thread groove moves up, and the support ring 501 rotates relative to the support frame 604 and the threaded rod 601. After the drilling is completed, the drill bit 4 stops rotating and exits the drilling. The elastic force of the return spring 603 is used to push the threaded rod 601 and the support frame 604 downward, so that the support ring 501 rotates and moves downward, driving the cleaning head 503 to remove the drill bit residue along the thread groove, effectively solving the problem that the drill bit of the previous drilling machine is entangled with the residue and affects the next operation of the drill bit. At the same time, it solves the problem that the cleaning is inconvenient and easy to scratch when removing the residue manually.
