[0002] With the development of the aviation industry, the requirements for the precision, surface quality, and production efficiency of aircraft parts are increasing. Traditional grinding techniques and equipment are gradually showing their limitations in meeting these demands. For example:

[0003] Traditional grinding methods typically rely on manual operation or semi-automatic equipment, making it difficult to ensure accurate grinding of complex-shaped and high-precision aircraft parts. This not only affects the quality of the final product but may also cause parts to fail to meet stringent aviation standards. The grinding process generates a large number of fine metal shavings. If these shavings are not effectively collected and treated, they may contaminate the working environment and even threaten the health of operators. In addition, improperly treated shavings may re-adhere to the parts being processed, affecting surface quality and subsequent processes.

[0004] To address these issues, we provide a grinding equipment for the precision machining of aircraft parts. Utility Model Content

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.

[0025] Example

[0026] Please see Figure 1-4 This utility model relates to a grinding device for precision machining of aircraft parts, comprising a base plate 100, a position adjustment assembly 200 mounted on the upper side of the base plate 100, a grinding assembly 400 cooperating with the position adjustment assembly 200, and a collection assembly 300 for collecting grinding debris. The position adjustment assembly 200 includes a cylinder 201 fixed to the upper side of the base plate 100, an L-shaped mounting bracket 203 connected to the telescopic end of the cylinder 201, and a mounting plate 20 fixed to the top and back of the L-shaped mounting bracket 203. 4, and a guide rail 202 that movably engages with the bottom of the L-shaped mounting bracket 203; the grinding assembly 400 includes a shaft cover 401 symmetrically mounted in the middle of the vertical surface of the L-shaped mounting bracket 203, a drive shaft rotatably disposed inside the shaft cover 401, and a grinding head fixed at the end of the drive shaft; the collection assembly 300 includes a collection box 301 fixed to the upper side of the bottom of the L-shaped mounting bracket 203, a collection drawer 302 embedded inside the collection box 301, and a negative pressure pipe 303 connecting to the tail of the collection box 301.

[0027] Specifically, a motor 402 is fixed to the outside of the mounting plate 204, and a drive wheel 405 is connected to the output end of the motor 402. The drive wheel 405 is connected to a transmission wheel 403 via a belt 404. The transmission wheel 403 is fixed to the end of the transmission shaft. The drive wheel 405 is rotatably mounted on the top back of the L-shaped mounting bracket 203. An adjusting wheel for adjusting the tension of the belt 404 is provided on the side of the L-shaped mounting bracket 203. This transmission system ensures the stability and high-speed rotation of the grinding head during operation, providing efficient grinding capability. At the same time, the adjusting wheel for adjusting the tension of the belt 404 can adjust the tension of the belt 404 to ensure transmission efficiency.

[0028] The collection drawer 302 has a feed inlet 3021 on the outer middle and a filter surface 3023 on the inner end. The top opening of the collection chamber 3022 inside the collection drawer 302 is fitted to the inner wall of the collection box 301. A gap for air flow is provided between the filter surface 3023 and the innermost end of the collection box 301. Through negative pressure suction, the debris generated during the grinding process is sucked into the collection box 301 from the feed inlet 3021 and separated from the air by the filter surface 3023, avoiding environmental pollution and protecting the health of the operators. After the collection drawer 302 is removed, the opening at the top of the collection chamber 3022 is designed to facilitate cleaning the waste inside. After the collection drawer 302 is inserted into the collection box 301, its top opening is fitted to the inner wall of the collection box 301 to prevent waste from passing through.

[0029] Furthermore, a limiting groove 101 is provided on the side of the base plate 100, and the negative pressure pipe 303 passes through the limiting groove 101. The extension end of the negative pressure pipe 303 is a corrugated pipe, which is connected to the external negative pressure equipment. The limiting groove 101 ensures that the position of the negative pressure pipe 303 is fixed, preventing damage caused by accidental pulling. The corrugated pipe increases the flexibility of the negative pressure pipe 303 and facilitates connection with the external negative pressure equipment.

[0030] The guide rail 202 is symmetrically fixed to the front of the upper side of the base plate 100. The guide rail 202 is parallel to the extension and retraction direction of the cylinder 201, so that the grinding head can move precisely along the preset path, thereby ensuring efficient and accurate grinding of complex-shaped aircraft parts.

[0031] The specific operation steps in this embodiment are as follows:

[0032] At the start of operation, the L-shaped mounting bracket 203 is driven by the control cylinder 201 to move along the guide rail 202 to the starting position, which is preset according to the specific shape and size of the aircraft parts to be ground. Then, the aircraft parts to be processed are fixed in a suitable position, and the motor 402 is started. The output end of the motor 402 drives the drive wheel 405 to rotate. The drive wheel 405 transmits power to the transmission wheel 403 through the belt 404, thereby causing the transmission shaft and the grinding head mounted on it to rotate at high speed. During the grinding process, as the L-shaped mounting bracket 203 moves precisely along the guide rail 202 under the precise control of the cylinder 201, the grinding head performs precise grinding on the aircraft parts. At the same time, the negative pressure equipment is started, and air is drawn from the collection box 301 through the negative pressure pipe 303, generating negative pressure in the collection drawer 302. This causes the grinding debris to be sucked into the collection chamber 3022 through the feed inlet 3021. The filter surface 3023 can effectively prevent debris from entering the negative pressure system, ensuring clean air discharge.
