[0025] Reference Figure 1A guide-guided drilling fixture includes: a mounting base 100, a fixing structure 200, a guide seat 300, and a connecting structure 400. The mounting base 100 is provided with a positioning hole 185. The fixing structure 200 is disposed on the mounting base 100 and is used to connect the mounting base 100 and the workpiece 900 and to position the positioning hole 185 and the workpiece 900. The guide seat 300 is provided with a mounting position 380 for mounting a drill rig 800. The connecting structure 400 is disposed between the guide seat 300 and the mounting base 100 and connects the two. The connecting structure 400 can relative position the positioning hole 185 and the mounting position 380, and make the central axis of the positioning hole 185 flush with the central axis of the drill bit 850 of the drill rig 800. The fixing structure 200 allows the fixture to be stably mounted on the inclined surface of the workpiece 900 and prevents positional displacement due to vibration during the drilling process, thereby improving the stability and accuracy of the drilling. Based on this, the positioning hole 185 on the mounting base 100 and the mounting position 380 on the guide seat 300 are precisely positioned relative to each other through the connecting structure 400, ensuring that the central axis of the positioning hole 185 is flush with the central axis of the drill bit 850 of the drill gun 800. This ensures that the drill gun 800 can perform high-precision drilling operations on the inclined surface of the workpiece 900. The cooperation between the mounting base 100 and the guide seat 300 not only improves product quality but also reduces the scrap rate caused by drilling errors, saving production costs. It is suitable for various scenarios that require high-precision drilling on inclined surfaces and has broad industrial application value.

[0026] In some embodiments, reference is made to Figure 3 The mounting base 100 is provided with a positioning part 180 and a mounting part 120. The mounting part 120 is mounted to the workpiece 900 via a fixing structure 200. The positioning part 180 is fitted to the surface of the workpiece 900 to be drilled, and a positioning hole 185 is provided in the positioning part 180. The positioning part 180 and the mounting part 120 perform different functions. The positioning part 180 fits tightly to the surface of the workpiece 900 to be drilled, according to the shape and angle of the bevel, ensuring the precise correspondence between the positioning hole 185 and the position of the hole to be drilled. The mounting part 120 is connected to the workpiece 900 via the fixing structure 200, providing a stable mounting base and enhancing the fixing effect of the fixture on the workpiece 900. This separate design allows the positioning part 180 to focus on the positioning function and the mounting part 120 to focus on the fixing function. The two work together to improve the positioning accuracy and installation stability of the fixture, further improving the drilling quality and adapting to the bevel drilling requirements of workpieces 900 with different shapes and sizes.

[0027] It is foreseeable that the shape of the positioning part 180 can be optimized according to the inclined shape of the common workpiece 900, such as setting it as an adjustable angle structure to adapt to the requirements of inclined opening at different inclination angles; or setting anti-slip texture on the surface of the positioning part 180 to be drilled to enhance the friction between the positioning part 180 and the workpiece 900 and prevent the fixture from sliding during the opening process.

[0028] In some embodiments, reference is made to Figure 2 The fixing structure 200 includes bolts mounted on the mounting part 120, which bolts connect the mounting part 120 and the workpiece 900. Bolt connections offer advantages such as high connection strength, good stability, and ease of disassembly and installation. Through bolt connections, the mounting base 100 can be firmly fixed to the workpiece 900, effectively resisting various forces generated during the drilling process, preventing the mounting base 100 from shifting or loosening, and ensuring the accuracy of the drilling position. Simultaneously, bolt connections facilitate quick installation and disassembly, improving production efficiency and making them suitable for various processing applications requiring frequent changes to the workpiece 900 or adjustments to the drilling position, thus enhancing the practicality and flexibility of the fixture.

[0029] It is conceivable that the fixing structure 200 can also be composed of other components, such as connecting and fixing the mounting base 100 and the workpiece 900 by means of clips or adhesives. The specific implementation method is not unique, but can be adjusted according to the actual situation, and is not limited here.

[0030] In some embodiments, reference is made to Figure 2 There are two mounting parts 120, located on either side of the positioning part 180. Each mounting part 120 is fixedly mounted to the workpiece 900 via a fixing structure 200. The design of two mounting parts 120 on either side of the positioning part 180 ensures a more balanced and stable fixation of the fixture on the workpiece 900. The two mounting parts 120 are connected to the workpiece 900 via the fixing structure 200, forming supports on both sides of the positioning part 180, enhancing the torsional resistance and stability of the fixture on the workpiece 900. This design effectively prevents the fixture from tilting or shifting due to single-point fixing during the drilling process, ensuring a long-term accurate correspondence between the positioning hole 185 and the position to be drilled, improving the consistency and reliability of the drilling process. It is particularly suitable for machining complex workpieces 900 with high drilling accuracy requirements.

[0031] In some embodiments, reference is made to Figure 3The guide seat 300 is plate-shaped, with the mounting position 380 located in the middle, ensuring that the central axis of the drill bit 850 of the drill gun 800 is perpendicular to the guide seat 300. The positioning part 180 is parallel to the guide seat 300. This plate-shaped design provides stable support and precise guidance for the drill gun 800, ensuring that the drill bit 850 remains perpendicular to the inclined plane during the drilling process, thus improving the perpendicularity and accuracy of the drilling. The plate-shaped guide seat 300 has a large contact area, which can evenly distribute the pressure of the drill gun 800, reducing damage to the surface of the workpiece 900, and improving the overall stability and service life of the fixture. Furthermore, this design facilitates operator observation and control of the drilling process, further improving processing quality and efficiency.

[0032] In some embodiments, reference is made to Figure 2 The connecting structure 400 includes multiple screws 420. One end of each screw 420 is distributed around the positioning hole 185 and connected to the mounting base 100, while the other end of each screw 420 is distributed around the mounting position 380 and connected to the guide seat 300. This screw 420 connection method not only provides a reliable mechanical connection, ensuring a tight fit between the mounting base 100 and the guide seat 300, but also allows for precise positioning and calibration by adjusting the tightness of the screws 420. The design of multiple screws 420 distributed around the mounting base ensures uniform distribution of the connecting force, enhancing the stability and torsional resistance of the connecting structure 400. This effectively resists various complex forces generated during the drilling process, ensuring a stable relative positional relationship between the positioning hole 185 and the mounting position 380, improving the repeatability and reliability of the drilling process, and making it suitable for various high-precision drilling requirements.

[0033] Specifically, there are two screws 420, located on both sides of the mounting position 380. Of course, the number of screws 420 can also be three, four, or more. The specific implementation is not unique and can be adjusted according to the actual situation. No limitation is made here.

[0034] In some embodiments, reference is made to Figure 3One end of the screw 420 is threadedly connected to the mounting base 100, and the other end of the screw 420 is slidably inserted into the guide seat 300. A return spring 430 is sleeved on the outer periphery of the screw 420, which can elastically push the guide seat 300. The sliding connection between the screw 420 and the guide seat 300 gives the guide seat 300 a certain floating ability, which can automatically adapt to the gradual deepening movement of the drill gun 800 during the drilling process and ensure that the drill bit 850 always maintains precise alignment with the positioning hole 185. The elastic action of the return spring 430 can provide a stable pushing force, making the guide seat 300 fit tightly against the drill gun 800, and at the same time, it can make appropriate clearance when subjected to external forces, avoiding equipment damage caused by hard collisions, and improving the flexibility and service life of the equipment. In addition, this floating design can also improve the versatility and adaptability of the fixture, enabling it to better cope with different processing conditions and workpiece 900 clamping states.

[0035] In some embodiments, reference is made to Figure 3 The screw 420 is connected to a nut 410, and the nut 410 and the return spring 430 are located on both sides of the guide seat 300 and can cooperate to press the guide seat 300. By adjusting the position of the nut 410, the extension length between the screw 420 and the guide seat 300 can be precisely controlled, thereby achieving fine adjustment and locking of the position of the guide seat 300. This design allows the operator to perform precise positioning and calibration of the fixture before drilling, ensuring that the positioning hole 185 is highly precisely aligned with the central axis of the drill bit 850 of the drill gun 800. At the same time, the cooperation of the nut 410 and the return spring 430 provides a stable clamping force, ensuring that the guide seat 300 maintains its orientation angle throughout the drilling process, further improving the accuracy and stability of drilling and meeting the requirements of high-precision machining.

[0036] It is conceivable that the guide seat 300 could also be limited by setting a step at the end of the screw 420. The specific implementation method is not unique, but can be adjusted according to the actual situation, and is not limited here.

[0037] In some embodiments, reference is made to Figure 2 The screw 420 is a double-ended screw 420, with one end threadedly connected to the mounting base 100 and the other end threadedly connected to the nut 410. The use of the double-ended screw 420 makes the connection between the mounting base 100 and the guide seat 300 more compact, reducing the number of parts and assembly time, and lowering production costs. At the same time, the threaded connection at both ends of the double-ended screw 420 provides a wider adjustment range and stronger locking force, better adapting to mounting bases 100 and guide seats 300 of different thicknesses, as well as positioning holes 185 and mounting positions 380 with different spacing, enhancing the versatility and flexibility of the fixture, making it suitable for various industrial processing scenarios.

[0038] In some embodiments, reference is made to Figure 1 The mounting position 380 is configured as a hole for mounting the drill rig 800, and the central axis of the mounting position 380 coincides with the central axis of the positioning hole 185. This coincidence ensures that the drill rig 800 is precisely coaxial with the positioning hole 185 after installation, thus guaranteeing that the drill bit 850 remains highly aligned with the positioning hole 185 during the drilling process, improving the accuracy and quality of the drilling. The shape and size of the hole match the shape of the drill rig 800, providing stable support and positioning, preventing the drill rig 800 from shaking or shifting during drilling. This precise coaxial design is key to achieving high-precision bevel drilling, effectively reducing machining errors, improving product yield, and is suitable for various machining tasks with stringent drilling accuracy requirements.

[0039] In summary, for the inclined surface drilling operation, based on the surface of the workpiece 900 to be drilled, the drilling fixture is secured to the front hole near the workpiece 900 using bolts and nuts 410. Then, a suitable drill bit 850 is selected and mounted on the drill gun 800. The drill bit 850 is pressed down at an angle perpendicular to the shank of the drill gun 800, and the rocker arm 820 is rotated. Under the constraint of the guide seat 300 and the double-ended screw 420, the drill bit 850 is made perpendicular to the surface of the workpiece 900 to drill the hole. After drilling is completed, the shank of the drill gun 800 can be released. Under the action of the return spring 430, the drill gun 800 will return to its initial height, thus facilitating the separation of the mounting base 100 and the workpiece 900.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
