Description

Technical Field

[0001] This utility model relates to the field of drilling device technology, specifically a drilling device for automotive turbine rotor shafts. Background Technology

[0002] The drilling device for automotive turbine rotor shafts is a specialized piece of equipment designed specifically for their high-precision machining requirements, focusing on drilling critical components such as turbine rotor shafts in automotive powertrain systems. This device addresses the material properties of the turbine rotor shaft (such as high-strength alloy steel and nickel-based high-temperature alloys) and the required hole position accuracy (typically within ±0.02mm). Through precise control and efficient execution, it ensures a stable and reliable drilling process. In actual machining, the device can adapt to the clamping requirements of turbine rotor shafts of different specifications, quickly positioning and fixing the shaft using specialized fixtures to ensure accurate drilling positions. During operation, it automatically matches appropriate drill bit speed and feed rate based on material hardness and hole diameter—for example, for high-temperature alloy shafts, a low speed and small feed parameters are used to reduce drill bit wear. Simultaneously, a cooling and lubrication system continuously supplies cutting fluid to lower the temperature of the machining area and flush away chips, preventing burns or scratches on the hole walls. This device significantly improves the efficiency and consistency of drilling turbine rotor shafts, reducing the processing time per piece by more than 30% compared to traditional methods. Furthermore, the finished product's hole accuracy and surface quality fully meet the stringent standards of automotive engines for turbine rotor shafts. It is a core processing equipment for ensuring stable turbocharger performance and extending service life.

[0003] While the drilling device used for automotive turbine rotor shafts can meet the requirements of high-precision drilling, it has the problem of inconvenient drill bit disassembly and replacement in actual use: the traditional chuck structure requires multiple tightening with a special wrench to loosen the fixation, which is cumbersome and time-consuming; the space for drill bit installation is narrow, and the tool is prone to interference with surrounding parts during disassembly, which increases the difficulty of operation; in addition, the chuck is prone to uneven tightening force during frequent disassembly and assembly, which can cause the drill bit to be unstable, affecting the subsequent processing accuracy and reducing the efficiency of equipment maintenance. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drilling device for an automotive turbine rotor shaft, comprising a base, a clamp at the upper end of the base, a cylinder fixedly mounted at the upper end of the base, a mounting bracket fixedly connected to the output end of the cylinder, a motor fixedly connected to the upper end of the mounting bracket, a mounting seat contacting the lower end of the mounting bracket, a limiting block rotatably connected inside the mounting seat, a limiting sleeve fixedly connected to the lower end of the limiting block, the limiting sleeve contacting the mounting seat, a drill bit slidably connected inside the mounting seat, the drill bit movably connected to the limiting block, the drill bit and the limiting sleeve being threadedly connected, a positioning frame fixedly connected to the outer side of the drill bit, and a support mechanism provided on the base.

[0013] 2.

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.

[0017] Please see Figure 1-4A drilling device for automotive turbine rotor shafts includes a base 1, a clamp 11 at the upper end of the base 1, a cylinder 12 fixedly mounted at the upper end of the base 1, a mounting bracket 13 fixedly connected to the output end of the cylinder 12, a motor 14 fixedly connected to the upper end of the mounting bracket 13, the output end of the motor 14 rotatably connected to the mounting bracket 13, and the output end of the motor 14 fixedly connected to the mounting seat 2. Through the design of the motor 14, the mounting seat 2 can be driven to rotate. The lower end of the mounting bracket 13 contacts the mounting seat 2, and a limit block 21 is rotatably connected inside the mounting seat 2.

[0018] Please see Figure 2-4 A protrusion 22 is fixedly connected to the outer side of the limiting block 21. The protrusion 22 is rotatably connected to the mounting base 2. The protrusion 22 can limit the limiting block 21. A limiting sleeve 23 is fixedly connected to the lower end of the limiting block 21. The limiting sleeve 23 is in contact with the mounting base 2. A drill bit 24 is slidably connected inside the mounting base 2. The drill bit 24 is movably connected to the limiting block 21. The drill bit 24 is threadedly connected to the limiting sleeve 23. A positioning frame 25 is fixedly connected to the outer side of the drill bit 24. The positioning frame 25 is in contact with the limiting sleeve 23. The positioning frame 25 is slidably connected to the mounting base 2. The positioning frame 25 can position the drill bit 24. A support mechanism 3 is provided on the base 1.

[0019] Please see Figure 2-4 The support mechanism 3 includes a support base 31. The support base 31 is fixedly connected to the outer side of the base 1. The outer side of the support base 31 contacts a support plate 32. The lower end of the support plate 32 is fixedly connected to a support base 33. A connecting block 34 is fixedly connected to the side of the support plate 32 near the support base 31. The connecting block 34 is slidably connected to the support base 31. A threaded rod 35 is rotatably connected inside the support base 31. A retaining ring 36 is fixedly connected to the outer side of the threaded rod 35. The retaining ring 36 contacts the inner wall of the support base 31. The retaining ring 36 can limit the movement of the threaded rod 35. The threaded rod 35 is connected to the connecting block 34 by threads. A knob 37 is fixedly connected to the upper end of the threaded rod 35. The knob 37 contacts the support base 31. The knob 37 can be easily rotated. The design of the support mechanism 3 can keep the equipment stable during use.

[0020] The specific implementation process of this utility model is as follows: In use, the threaded rod 35 is driven to rotate by rotating the knob 37. The threaded rod 35 and the connecting block 34 form a precise threaded fit, which drives the connecting block 34 to move smoothly along the axial direction of the threaded rod 35. The displacement of the connecting block 34 is transmitted to the support plate 32 through the support rod, which in turn pushes the support base 33 to extend and retract, so as to realize the independent fine adjustment of the position of each support point of the base 1. This design can dynamically compensate for uneven ground or equipment center of gravity shift. Through the coordinated optimization of the three-point or four-point support system, it ensures that the base 1 always maintains a horizontal and stable state during the drilling process, effectively avoiding processing errors caused by vibration and improving the accuracy and reliability of drilling the turbine rotor shaft.

[0021] When drill bit 24 needs to be replaced, rotating the limiting sleeve 23 drives it to form a reverse threaded motion with the drill bit 24, causing the drill bit 24 to move axially and disengage from the clamping area of ​​the limiting sleeve 23. As the drill bit 24 moves, the positioning bracket 25 connected to its end slides out of the guide groove of the mounting base 2, ultimately achieving the complete disengagement of the drill bit 24. This operation does not require additional tools; the drill bit 24 can be quickly disassembled by simply unscrewing the limiting sleeve 23. This solves the problem of difficult disassembly and assembly caused by thread jamming or space constraints in traditional devices, significantly shortening the maintenance time of the drill bit 24 and ensuring efficient and continuous operation of the equipment. These two optimized designs, focusing on equipment stability and ease of maintenance, significantly improve the overall performance of the drilling device.
