[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 This utility model provides a technical solution: a drilling device for processing automotive interior parts, including a handheld drilling machine 1. The handheld drilling machine 1 provides power and ease of operation. The user holds it in their hand and controls the rotation of the drilling head 2 through a switch, which facilitates drilling operations on automotive interior parts at different locations and flexibly adapts to various drilling needs. The handheld drilling machine 1 is provided with a mounting base 101, and the drilling head 2 is installed inside the mounting base 101. The mounting base 101 provides a stable mounting foundation for the drilling head 2, ensuring that the drilling head 2 maintains the correct position and posture during operation, which is conducive to ensuring the drilling accuracy.

[0025] The outer wall of the mounting base 101 is threaded to fit the first mounting ring 3. The first mounting ring 3 is threaded to the mounting base 101, which facilitates installation and disassembly, and makes it easy to assemble, repair and replace parts of the drilling device. The bottom surface of the first mounting ring 3 is movably mounted with the telescopic component 5, and the bottom end of the telescopic component 5 is movably mounted with the second mounting ring 4. The opposite side of the first mounting ring 3 and the second mounting ring 4 is provided with a mounting groove 6. Both ends of the telescopic component 5 are slidably fitted inside the mounting groove 6. The side walls of the first mounting ring 3 and the second mounting ring 4 are provided with threaded holes 7.

[0026] The telescopic assembly 5 includes a telescopic rod 501, with two mounting plates 502 installed at both ends of the telescopic rod 501. A spring 503 is installed between the two mounting plates 502, and the spring 503 is located outside the telescopic rod 501. L-shaped plates 504 are installed on each mounting plate 502, and threaded rods 505 are provided on the L-shaped plates 504. During drilling, the telescopic rod 501 and spring 503 of the telescopic assembly 5 can extend and retract according to the drilling pressure, which helps to accurately position the drilling head 2 at the required drilling position and ensure the accuracy of the drilling position. Through the extension and retraction buffer of the telescopic rod 501 and spring 503, the vibration and impact force generated by the drilling head 2 can be absorbed during the drilling process, reducing the shaking during drilling, improving the drilling stability of the drilling head 2, thereby improving the drilling quality and making the drilled hole more regular.

[0027] One end of the threaded rod 505 is threaded into the threaded hole 7. Threaded holes 7 are opened on the first mounting plate 3 and the second mounting ring 4 for installation with the telescopic component 5, making the entire device structure more stable. By removing the threaded rod 505, the L-shaped plate 504 inside the sliding mounting groove 6 can be easily removed between the first mounting ring 3 and the second mounting ring 4, making it convenient to repair and replace the telescopic component 5.

[0028] The first mounting ring 3, the second mounting ring 4, and the telescopic component 5 are all located outside the punching head 2. The hollow diameter of the first mounting ring 3 and the second mounting ring 4 is larger than that of the punching head 2. The first mounting ring 3 and the second mounting ring 4 are positioned opposite each other outside the punching head 2, which plays a positioning and guiding role for the punching head 2, ensuring that the punching head 2 moves along a predetermined direction during the punching process, thereby improving the straightness and accuracy of the punching.

[0029] A rubber pad 401 is provided on the bottom surface of the second mounting ring 4. The rubber pad 401 enhances the friction between the second mounting ring 4 and the interior trim, making the device less prone to slipping during drilling, and further improving the stability and accuracy of drilling. At the same time, the soft material of the rubber pad 401 fills the unevenness of the surface of the interior trim, allowing the second mounting ring 4 to fit better with the interior trim, providing more stable support for drilling, preventing the second mounting ring 4 from directly contacting the interior trim and causing scratches or damage, and protecting the surface quality of the automotive interior trim.

[0030] The protective cover 402 is installed in the hollow position on the top surface of the second mounting ring 4 by screws. The protective cover 402 is made of transparent material to prevent debris, dust and other particles from flying out during the drilling process, protecting the operator's safety and preventing debris from entering the eyes and other parts of the body and causing injury. At the same time, the transparent protective cover 402 allows the operator to observe the drilling situation at any time during the drilling process, such as whether the drilling depth and position are correct, so as to adjust the operation in time and ensure the drilling quality. The protective cover 402 has a hole, and the drilling head 2 moves through the hole of the protective cover 402.

[0031] When using a drilling device to process automotive interior parts, the user holds a handheld drilling machine 1, which is equipped with a switch. The first mounting ring 3, the second mounting ring 4, and the telescopic component 5 of the handheld drilling machine 1 are attached to the desired drilling position on the interior part. The rubber pad 401 of the second mounting ring 4 is attached to the interior part. The user controls the drilling head 2 of the handheld drilling machine 1 to rotate and drill through the switch. When drilling through the interior part, the drilling head 2 moves inside the first mounting ring 3, the second mounting ring 4, and the telescopic component 5, pressing the handheld drilling machine 1 so that the drilling head 2 enters the interior part to perform the drilling operation. This causes the telescopic rod 501 and the spring 503 of the telescopic component 5 to be pressed and retracted. The telescopic component 5 ensures drilling positioning and also helps the drilling head 2 to maintain drilling stability.
