Description

Technical Field

[0001] This utility model relates to the field of machining, and in particular to a milling device for compensating for blade profile errors. Background Technology

[0002] In high-end equipment manufacturing, the machining accuracy of blade profiles directly affects equipment performance. Traditional error compensation techniques correct errors by adjusting the entire trajectory motion data of the milling cutter, but they have significant drawbacks: they require the reconstruction of a massive number of tool positions, leading to a surge in computational load; global adjustments can disrupt preset process parameters, causing vibration and tool wear; and they suffer from lag in response to dynamic errors, resulting in low real-time compensation efficiency. These shortcomings limit the improvement of machining accuracy and efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a blade profile error compensation milling device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A blade profile error compensation milling device includes a fixed sleeve, a telescopic milling cutter, a cutter head, a position sensor, a semi-circular limiting groove, a semi-circular limiting slide rod, a sliding cavity, a reserved slot, and a dynamic compensation mechanism. The telescopic milling cutter is installed inside the front end of the fixed sleeve, and a cutter head is formed at the front end of the telescopic milling cutter. A position sensor is installed inside the center of the front end of the telescopic milling cutter. A semi-circular limiting groove is formed below the rear end of the fixed sleeve. A semi-circular limiting slide rod is integrally formed at the bottom of the rear end of the telescopic milling cutter and is installed in the semi-circular limiting groove, allowing it to slide back and forth within it. A sliding cavity is formed inside the fixed sleeve, and the entire telescopic milling cutter can slide back and forth within the sliding cavity. A reserved slot is formed above the rear end of the sliding cavity, and a dynamic compensation mechanism is installed within the reserved slot. The dynamic compensation mechanism is connected to the telescopic milling cutter and can control the micro-movement of the telescopic milling cutter.

[0005] Preferably, the dynamic compensation mechanism further includes a high-precision telescopic motor and a telescopic rod. The high-precision telescopic motor is installed in the reserved slot, and the telescopic rod is installed at the front end of the high-precision telescopic motor. The front end of the telescopic rod is fixedly connected to the rear end of the telescopic milling cutter and drives the telescopic milling cutter to move back and forth slightly. The high-precision telescopic motor determines the position of the cutter head through a position sensor, verifies the real-time position of the cutter head through the CNC machine tool program, and controls the high-precision telescopic motor to adjust in real time to make error compensation, so as to avoid the need to adjust the overall movement trajectory of the milling cutter.

[0006] The beneficial effects of this utility model are: the utility model is reasonably designed, and the milling cutter can move back and forth slightly in the sleeve through the dynamic compensation mechanism to achieve error compensation and avoid modifying the full trajectory motion data of the milling cutter.

The telescopic milling cutter 2 is installed inside the front end of the fixed sleeve 1. The telescopic milling cutter 2 has a cutter head 3 at its front end, and the position sensor 4 is installed inside the center of the front end of the telescopic milling cutter 2. A semi-circular limiting groove 5 is opened below the rear end of the fixed sleeve 1. A semi-circular limiting slide rod 6 is integrally formed at the bottom of the rear end of the telescopic milling cutter 2 and is installed in the semi-circular limiting groove 5, and can slide back and forth inside it. A sliding cavity 7 is opened inside the fixed sleeve 1, and the entire telescopic milling cutter 2 can slide back and forth inside the sliding cavity 7. A reserved groove 8 is opened above the rear end of the sliding cavity 7. A dynamic compensation mechanism 9 is installed in the reserved groove 8 and is connected to the telescopic milling cutter 2, and can control the micro-movement of the telescopic milling cutter 2 back and forth. The dynamic compensation mechanism 9 also includes a high-precision telescopic motor 10 and a telescopic rod 11. The high-precision telescopic motor 10 is installed in the reserved slot 8. The telescopic rod 11 is installed at the front end of the high-precision telescopic motor 10, and the front end of the telescopic rod 11 is fixedly connected to the rear end of the telescopic milling cutter 2, which drives the telescopic milling cutter 2 to move back and forth slightly.
