[0002] The production of aircraft engine blades often involves curved surface machining. In related technologies, this is primarily accomplished using milling machines. A milling machine primarily uses a milling cutter to mill various workpiece surfaces. The milling cutter typically rotates primarily, while the workpiece and cutter move in a feed motion. These machines can process flat surfaces, grooves, various curved surfaces, gears, and more. They can also produce relatively complex surfaces, offering higher efficiency than planers, making them widely used in machinery manufacturing and repair.

During the milling process, the smearing assembly evenly smears the coolant in the coolant tank to the surface of the milling cutter, thereby maintaining a cooling effect on the milling cutter while keeping the surface of the milling cutter clean, reducing the impact of debris adhesion on the milling work.

[0011] Furthermore, the filter assembly includes a collection trough, the outer wall of the collection trough is fixedly connected to the inner wall of the collection box, the bottom of the inner wall of the collection trough is symmetrically provided with a telescopic rod, the bottom of the telescopic rod is fixedly connected to the bottom of the inner wall of the collection trough, the top of the telescopic rod is fixedly connected to a filter plate, the inner wall of the collection trough is evenly opened with openings, the top of the collection trough is fixedly connected to a guide plate, the top of the guide plate is evenly opened with through holes, so that the coolant on the surface of smaller debris can be separated and collected, which not only reduces the content of impurities in the debris and enables smaller debris to be processed separately, but also enables the coolant to be recycled, thereby reducing production costs.

Large pieces of debris generated during milling are thrown out and hit the surface of the elastic plate. There is less coolant adhering to the surface of the large pieces of debris, which is led to the circular hole by the inclined elastic plate and the extension plate and falls into the collection box. The surface of the smaller pieces of debris is more adhered to by coolant, and mixing with the large pieces of debris will cause the coolant to be evenly smeared on the debris, making it difficult to filter and recover, resulting in waste of coolant.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1.

The present invention sets a protective mechanism to clean the surface of the workpiece during the milling process to reduce the adhesion of debris, directly collect the large debris generated during the milling process, and classify the large and smaller debris. The coolant on the surface of the smaller debris is accumulated, filtered and separated, which is convenient for the recovery of the coolant and reduces the damage to the parts caused by the accumulation of debris inside the machine.

[0016] 2. Large chips generated during milling are thrown out and hit the surface of the elastic plate. There is less coolant adhering to the surface of the large chips, and mixing with smaller chips will cause the coolant to be dispersed and smeared on the surface of the chips, making it difficult to recover. The present invention sets a filter component to separate and collect the coolant on the surface of the smaller chips, which not only reduces the content of impurities in the chips and enables smaller chips to be processed separately, but also enables the coolant to be recycled, thereby reducing production costs.

[0017] 3. The present invention sets a grading component to keep the end of the movable sheet in contact with the surface of the workpiece, cleans the debris on the surface of the workpiece, avoids obstacles when the milling cutter works on the blade surface, and affects the service life of the milling cutter. The larger and smaller debris generated in the milling process are collected and processed separately, thereby improving the recycling rate of the coolant and strengthening the cleaning of the debris surface.

[0018] 4. The present invention sets a smearing component to keep the scraper in contact with the surface of the milling cutter. After the milling cutter rotates, the coolant in the coolant tank enters the shell through the infusion tube, flows out from the inside of the shell along the liquid outlet, and is then evenly scraped by the scraper, so that the coolant is quickly and evenly smeared on the surface of the milling cutter during the rotation of the milling cutter. At the same time, the output of the coolant is controlled, and the coolant is reduced from being thrown out and causing the coolant to adhere to the inside of the equipment, making it difficult to clean. The surface of the milling cutter is kept clean, the adhesion of debris is reduced, and the use effect of the milling cutter is maintained. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The milling equipment for engine blade processing also includes:

[0032] The protection mechanism 3 is used to collect and separate flying debris during milling. The bottom of the protection mechanism 3 is slidably connected to the bottom of the inner wall of the machine platform 1.

[0033] The outer wall of the movable part 4 is rotatably connected to the milling mechanism 5, the inner wall of the machine table 1 is rotatably connected to the chuck 2, the chuck 2 clamps the workpiece for initial processing, and the inner wall of the machine table 1 is fixedly connected to the end away from the chuck 2 with a claw 6, which clamps the workpiece after rough processing.

[0034] During work, the worker places the workpiece to be processed inside the chuck 2 and clamps it. The moving part 4 drives the milling mechanism 5 close to the workpiece, and the chuck 2 drives the workpiece to rotate. During the rotation, the workpiece is processed into the initial shape of the engine blade. At this time, the protective mechanism 3 wraps the workpiece so that the debris generated by the workpiece during the milling process is collected by the protective mechanism 3. During the milling process, coolant is applied to the surface of the milling cutter 505 to maintain the temperature of the milling cutter 505. The protective mechanism 3 is externally connected to a blower to blow air downward from the top of the workpiece to ensure that the debris enters the inside of the protective mechanism 3. After the rough processing of the workpiece to complete the blade contour is completed, the workpiece is moved to the clamping claw 6, so that the milling mechanism 5 performs fine milling on the surface of the blade, and the protective mechanism 3 follows and moves to the position of the clamping claw 6 to collect the debris.

[0035] The protective mechanism 3 includes a lifting column 301, the bottom of the lifting column 301 is slidably connected to the bottom of the inner wall of the machine 1, the top of the lifting column 301 is fixedly connected to the collection box 302, the inner wall of the collection box 302 is fixedly connected to the filter component 303, and the top of the filter component 303 is fixedly connected to the grading component 306. The protective mechanism 3 also includes a drain pipe 304, the outer wall of the drain pipe 304 is fixedly connected to the outer wall of the collection box 302, and there are two drain pipes 304. The outer wall of the other drain pipe 304 is fixedly connected to the outer wall of the collection tank 3031. A protective shell 305 is symmetrically provided on the top of the collection box 302. The shape of the protective shell 305 enables it to The bottom of the protective shell 305 is rotatably connected to the top of the collection box 302, which covers most of the space around the workpiece. The distance between the protective shells 305 can be adjusted by rotation to facilitate shielding of workpieces of different diameters. The inner wall of the protective shell 305 is fixedly connected to the outer wall of the grading component 306. The top of the protective shell 305 is evenly provided with air pipes 307, and the air pipes 307 are externally connected to a blower to blow air to the surface of the workpiece. The outer wall of the air pipe 307 is fixedly connected to the inner wall of the protective shell 305. The inner wall of the collection box 302 is fixedly connected to a filter screen 308 on the side away from the filter component 303. The filter screen 308 once again quietly filters large and small pieces of debris.

[0036] After the workpiece is fixed, the milling mechanism 5 approaches the workpiece for milling. At this time, the lifting column 301 drives the protective shell 305 to move to both sides of the workpiece, so that the air supply pipe 307 blows air downward to the workpiece. A large amount of debris is generated during the milling process. The grading component 306 limits the larger debris and makes it fall into the collection box 302. The grading component 306 contacts the lower surface of the workpiece during the milling process, so that the large debris on the surface of the workpiece is cleaned in time to avoid affecting the milling process. The smaller debris is thrown away and passes through the grading component 306 to contact the inner wall of the protective shell 305. Since coolant will adhere to the surface of the milling cutter 505 during the milling process, the debris may adhere to the coolant after being generated, so that the smaller debris is lubricated to a certain extent and enters the interior of the filter component 303 along the smooth and inclined surface of the inner wall of the protective shell 305. After accumulation and filtration, the debris is cleaned into the filter box, and the drain pipe 304 collects and extracts the filtered coolant.

[0037] The workpiece surface is cleaned during the milling process to reduce the adhesion of debris. Large debris generated during the milling process is directly collected, and large and smaller debris are graded. The coolant on the surface of the smaller debris is accumulated, filtered and separated to facilitate the recovery of the coolant and reduce the damage to the parts caused by the accumulation of debris inside the machine 1.

[0038] The milling mechanism 5 includes a hydraulic rod 501, the outer wall of the hydraulic rod 501 is rotatably connected to the outer wall of the moving part 4, the end of the hydraulic rod 501 away from the moving part 4 is fixedly connected to the driving block 502, the inner wall of the driving block 502 is fixedly connected to the coolant tank 503, the bottom of the coolant tank 503 is fixedly connected to the smearing component 504, the bottom of the driving block 502 is rotatably connected to the milling cutter 505, the outer wall of the smearing component 504 is in contact with the outer wall of the milling cutter 505, the outer wall of the smearing component 504 is symmetrically provided with locking rods 506, the locking rods 506 ensure that the smearing component 504 always keeps in contact with the surface of the milling cutter 505, the outer wall of the locking rod 506 is rotatably connected to the outer wall of the smearing component 504, and the end of the locking rod 506 away from the smearing component 504 is rotatably connected to the bottom of the driving block 502.

[0039] After the workpiece is fixed, the moving part 4 and the hydraulic rod 501 drive the driving block 502 close to the workpiece. Under the rotation of the chuck 2, the milling cutter 505 gradually mills the workpiece into the shape of the engine blade. During the milling process, the application component 504 evenly applies the coolant in the coolant tank 503 to the surface of the milling cutter 505, maintaining the cooling effect on the milling cutter 505 while keeping the surface of the milling cutter 505 clean, reducing the impact of debris adhesion on the milling work.

[0040] Example 2, please refer to Figures 1-8The present invention provides a technical solution: on the basis of embodiment 1, the filter assembly 303 includes a collection tank 3031, the collection tank 3031 is annular and fits on the inner wall of the collection box 302, the outer wall of the collection tank 3031 is fixedly connected to the inner wall of the collection box 302, and a telescopic rod 3032 is symmetrically provided at the bottom of the inner wall of the collection tank 3031. The bottom of the telescopic rod 3032 is fixedly connected to the bottom of the inner wall of the collection tank 3031, and the top of the telescopic rod 3032 is fixedly connected to the filter plate 3033 The shape of the filter plate 3033 is the same as the inner wall of the collection tank 3031, which is annular. Openings 3034 are evenly opened on the inner wall of the collection tank 3031. Initially, the telescopic rod 3032 drives the elastic plate 3061 to a position higher than the opening 3034. The top of the collection tank 3031 is fixedly connected with a guide plate 3035. The guide plate 3035 is concave. Through holes 3036 are evenly opened on the top of the guide plate 3035. The through holes 3036 allow smaller debris to enter the collection tank 3031.

[0041] A large amount of debris is generated during milling. The larger debris is thrown by the workpiece to the surface of the grading component 306 and then flows into the collection box 302 by gravity. The smaller debris contacts the inner wall of the protective shell 305 through the grading component 306 and gradually moves downward to the top of the guide plate 3035. Then, it enters the collection tank 3031 through the guide plate 3035. The coolant adhering to the surface of the smaller debris flows through the protective shell 305 to the guide plate 3035 and finally enters the bottom of the collection tank 3031 and flows through the drain pipe 304. After a period of sedimentation and accumulation, a lot of debris accumulates on the surface of the filter plate 3033. At this time, the telescopic rod 3032 moves downward, so that the height of the filter plate 3033 is lower than the opening 3034, and the debris is discharged from the opening 3034 and accumulated in the collection box 302. Then, the debris continues to be collected, and the coolant on the surface of the smaller debris is separated and collected. This not only reduces the impurity content in the debris and enables smaller debris to be processed separately, but also allows the coolant to be recycled, thereby reducing production costs.

[0042] The grading component 306 includes an elastic plate 3061. The surface of the elastic plate 3061 is smooth and has great elasticity. The outer wall of the elastic plate 3061 is fixedly connected to the inner wall of the protective shell 305. The outer wall of the elastic plate 3061 is evenly provided with strip holes 3062. The outer wall of the elastic plate 3061 is evenly provided with support rods 3063. The outer wall of the support rod 3063 is fixedly connected to the outer wall of the elastic plate 3061. The inner wall of the support rod 3063 away from the elastic plate 3061 is fixedly connected with a rotating rod 3064. The outer wall of the rotating rod 3064 is rotatably connected to the inner wall of the protective shell 305. The outer wall of the rotating rod 3064 is evenly provided with movable pieces 3065. The material of the movable pieces 3065 is wear-resistant rubber and has a certain elasticity. The inner wall of the movable piece 3065 is fixed to the inner wall of the protective shell 305. The outer wall of the rotating rod 3064 is rotatably connected, and the inner wall of the protective shell 305 is rotatably connected to the side of the rotating rod 3064 close to the rotating rod 3064. The inner wall of the bent plate 3067 is evenly provided with elastic rods 3066, and the end of the elastic rod 3066 away from the bent plate 3067 is fixedly connected to the outer wall of the movable plate 3065. The bottom of the elastic plate 3061 is fixedly connected to an extension plate 3068. The extension plate 3068 connects the bottoms of the two elastic plates 3061, and a circular hole is provided in the middle of the extension plate 3068 to allow large pieces of debris to fall into the collection box 302. The bottom of the extension plate 3068 is fixedly connected to a connecting pipe 3069. The connecting pipe 3069 is made of elastic material, and the bottom of the connecting pipe 3069 is fixedly connected to the top of the guide plate 3035.

[0043] During milling, the bent plate 3067 rotates, causing the movable piece 3065 to approach the workpiece, so that the end of the movable piece 3065 contacts the surface of the workpiece. Due to the irregular shape of the workpiece, the distance between the workpiece and the movable piece 3065 is not fixed. At this time, the movable piece 3065 is driven by the elastic rod 3066 to contact the surface of the workpiece at different squeezing forces, so that the end of the movable piece 3065 is kept in contact with the surface of the workpiece, and the debris on the surface of the workpiece is cleaned, so as to avoid obstacles when the milling cutter 505 is working on the blade surface, which affects the service life of the milling cutter 505. The air supply pipe 307 is used to blow air to the top of the workpiece to reduce the debris flying upward. During the rotation of the bent plate 3067, the support rod 3063 is driven to rotate, and then the elastic plate 3061 is driven to vibrate, so that the debris on the surface of the elastic plate 3061 falls onto the guide plate 3035 and enters the collection tank 3031 for self-cleaning.

[0044] Large pieces of debris generated during milling are thrown out and hit the surface of the elastic plate 3061. The large pieces of debris have less coolant adhering to the surface, and are guided to the circular hole by the inclined elastic plate 3061 and the extension plate 3068, and fall into the collection box 302. The smaller pieces of debris have more coolant adhering to their surfaces, and mixing with the large pieces of debris will cause the coolant to be evenly spread on the debris, making it difficult to filter and recover, resulting in a waste of coolant. At the same time, the surface of the debris adhered to by the coolant is prone to adhesion of other impurities such as dust, which increases the difficulty of collecting and processing the debris.

[0045] The smear assembly 504 includes an infusion tube 5041, the top of the infusion tube 5041 is fixedly connected to the bottom of the coolant tank 503, the bottom of the infusion tube 5041 is fixedly connected to the shell 5042, the bottom of the shell 5042 is provided with a liquid outlet 5043, the liquid outlet 5043 is long, the inner wall of the shell 5042 is symmetrically provided with a connecting rod 5044, the outer wall of the connecting rod 5044 is fixedly connected to the inner wall of the shell 5042, and the connecting rod 5044 is fixedly connected to the inner wall of the shell 5042. The outer wall of 44 is evenly provided with scrapers 5045, the inner wall of the scraper 5045 is in socket with the outer wall of the connecting rod 5044, the scraper 5045 is made of wear-resistant rubber, and a protrusion is provided on the bottom of the scraper 5045 near the liquid outlet 5043. The outer wall of the scraper 5045 is fixedly connected with an extrusion rod 5046, and the extrusion rod 5046 has elasticity. The end of the extrusion rod 5046 away from the scraper 5045 is fixedly connected to the inner wall of the shell 5042.

[0046] 4 and 506. The screw thread 5042 of the embodiment of the present invention is fixed on the workpiece 504 by the screw thread 5043. The screw thread 5042 is fixed on the workpiece 5044 by the screw thread 5045. The screw thread 5042 is fixed on the workpiece 5044 by the screw thread 5045. The screw thread 5042 is fixed on the workpiece 5044 by the screw thread 5045.

[0047] The specific workflow is as follows:

[0048] After the worker places the workpiece to be processed inside the chuck 2 and clamps it, the moving part 4 drives the milling mechanism 5 close to the workpiece, and the chuck 2 drives the workpiece to rotate. During the rotation, the workpiece is processed into the initial shape of the engine blade. At this time, the protective mechanism 3 wraps the workpiece so that the debris generated during the milling process is collected by the protective mechanism 3. During the milling process, coolant is applied to the surface of the milling cutter 505 to maintain the temperature of the milling cutter 505. The protective mechanism 3 is externally connected to a blower to blow air downward from the top of the workpiece to ensure that the debris enters the inside of the protective mechanism 3. After the workpiece is fixed, the milling mechanism 5 approaches the workpiece for milling. At this time, the lifting column 301 drives the protective shell 305 to move to both sides of the workpiece, so that the air supply pipe 307 blows air downward to the workpiece. A large amount of debris is generated during the milling process, and the grading component 306 limits the larger debris and makes it fall into the collection area. In the collecting box 302, the grading component 306 contacts the lower surface of the workpiece during the milling process, so that large debris on the surface of the workpiece is cleaned in time to avoid affecting the milling process. Smaller debris is thrown away and passes through the grading component 306 to contact the inner wall of the protective shell 305. Since coolant will adhere to the surface of the milling cutter 505 during the milling process, the debris may adhere to the coolant after it is generated, so that the smaller debris will be lubricated to a certain extent and enter the interior of the filter component 303 along the smooth and inclined surface of the inner wall of the protective shell 305. After accumulation and filtration, the debris is cleaned into the filter box, and the drain pipe 304 collects and extracts the filtered coolant. After the rough processing of the workpiece to complete the blade contour is completed, the workpiece is moved to the clamping claw 6, so that the milling mechanism 5 performs fine milling on the surface of the blade, and the protective mechanism 3 follows and moves to the position of the clamping claw 6 to collect the debris.

[0049] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them.
