There is less coolant adhering to the surface of the large pieces of debris, which are led to the circular hole by the inclined elastic plate and the extension plate and fall into the collection box. The surface of smaller debris is adhered to more coolant, and mixing with large 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, classify the large and smaller debris, and accumulate, filter and separate the coolant on the surface of the smaller debris, so as to facilitate the recovery of the coolant and reduce the damage to the parts caused by the accumulation of debris inside the machine.

[0016] 2. 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. Mixing with smaller debris will cause the coolant to be dispersed and smeared on the surface of the debris, making it difficult to recover. The present invention separates and collects the coolant on the surface of the smaller debris by setting a filter component, which not only reduces the content of impurities in the debris and enables the smaller debris to be processed separately, but also enables the coolant to be recycled, thereby reducing production costs.

[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 to reduce the coolant being thrown out and causing the inside of the equipment to adhere to the coolant, resulting in difficulty in cleaning, thereby keeping the surface of the milling cutter clean, reducing the adhesion of debris, and maintaining the use effect of the milling cutter.

[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, and the bottom of the protection mechanism 3 is slidably connected to the bottom of the inner wall of the machine table 1 .

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

[0034] During operation, a worker places the workpiece to be processed inside the chuck 2 and clamps it. The moving component 4 drives the milling mechanism 5 to approach 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 from the top of the workpiece downward 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 protection 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 assembly 303, and the top of the filter assembly 303 is fixedly connected to the grading assembly 306. The protection 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 two drain pipes 304 are provided. The outer wall of the other drain pipe 304 is fixedly connected to the outer wall of the collection tank 3031. The top of the collection box 302 is symmetrically provided with a protective shell 305, and 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 collecting 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, which 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 collecting 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 filters large and small 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 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 it is 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 accumulation of debris inside the machine 1 to cause damage to the parts.

[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 keep the smearing component 504 in contact with the surface of the milling cutter 505 at all times, 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 component 4 and the hydraulic rod 501 drive the driving block 502 to approach 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 coating component 504 evenly coats the coolant in the coolant tank 503 to the surface of the milling cutter 505, which maintains 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 Figure 1-Figure 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 the bottom of the inner wall of the collection tank 3031 is symmetrically provided with a telescopic rod 3032, 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 collecting groove 3031, which is annular. The inner wall of the collecting groove 3031 is evenly provided with openings 3034. Initially, the telescopic rod 3032 drives the elastic plate 3061 to be located at a position higher than the opening 3034. The top of the collecting groove 3031 is fixedly connected with a guide plate 3035. The guide plate 3035 is a concave surface. The top of the guide plate 3035 is evenly provided with through holes 3036. The through holes 3036 allow smaller debris to enter the collecting groove 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 enters 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, passes through the guide plate 3035 and enters the collection tank 3031. 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, there is a lot of debris accumulated on the surface of the filter plate 3033. At this time, the telescopic rod 3032 moves downward to make the height of the filter plate 3033 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, which not only reduces the content of impurities in the debris and enables the smaller debris to be processed separately, but also enables 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 sheets 3065. The material of the movable sheets 3065 is wear-resistant rubber and has a certain elasticity. The inner wall of the movable sheet 3065 is connected to 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 a bent plate 3067 on one side close to the rotating rod 3064. The inner wall of the bent plate 3067 is evenly provided with elastic rods 3066, and one end of the elastic rod 3066 away from the bent plate 3067 is fixedly connected to the outer wall of the movable sheet 3065. The bottom of the elastic plate 3061 is fixedly connected to an extension plate 3068, and 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, so that large pieces of debris fall into the collection box 302, and the bottom of the extension plate 3068 is fixedly connected to a connecting pipe 3069, and 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 to make the movable sheet 3065 approach the workpiece, so that the end of the movable sheet 3065 contacts the surface of the workpiece. Due to the irregular shape of the workpiece, the distance between the workpiece and the movable sheet 3065 is not fixed. At this time, the movable sheet 3065 is subjected to different extrusion forces when it contacts the surface of the workpiece driven by the elastic rod 3066. The end of the movable sheet 3065 is kept in contact with the surface of the workpiece to clean up the debris on the surface of the workpiece, so as to avoid obstacles when the milling cutter 505 works on the blade surface, which affects the service life of the milling cutter 505. The air 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 to achieve 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 adhered to the surface, and are led 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 adhered to the surface, 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 the coolant is prone to adhesion of other impurities such as dust, which increases the difficulty of debris collection and processing.

[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 a shell 5042, the bottom of the shell 5042 is provided with a liquid outlet 5043, the liquid outlet 5043 is in a long strip shape, the inner wall of the shell 5042 is symmetrically provided with connecting rods 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 the connecting rod 5044 is evenly provided with scrapers 5045, the inner wall of the scraper 5045 is sleeved with the outer wall of the connecting rod 5044, the scraper 5045 is made of wear-resistant rubber, the bottom of the scraper 5045 is provided with a protrusion on one side close to the liquid outlet 5043, the outer wall of the scraper 5045 is fixedly connected with an extrusion rod 5046, the extrusion rod 5046 has elasticity, and one end of the extrusion rod 5046 away from the scraper 5045 is fixedly connected to the inner wall of the shell 5042.

[0046] Before milling, the locking rod 506 drives the housing 5042 to approach the surface of the milling cutter 505 and move up and down along the axis of the milling cutter 505. The bottom of the scraper 5045 contacts the surface of the milling cutter 505. In the process of gradual fitting, the scraper 5045 moves outward, so that the extrusion rod 5046 is subjected to an extrusion force to keep the scraper 5045 in contact with the surface of the milling cutter 505. After the milling cutter 505 rotates, the coolant in the coolant tank 503 enters the housing 5042 through the infusion tube 5041, flows out from the inside of the housing 5042 along the liquid outlet 5043, and is then evenly scraped by the scraper 5045, so that the coolant is quickly and evenly applied to the surface of the milling cutter 505 during the rotation of the milling cutter 505. At the same time, the amount of coolant discharged is controlled to reduce the coolant being thrown out and causing the inside of the equipment to adhere to the coolant, resulting in difficulty in cleaning, thereby keeping the surface of the milling cutter 505 clean, reducing the adhesion of debris, and maintaining the use effect of the milling cutter 505.

[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 component 4 drives the milling mechanism 5 to approach 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 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 to the collection 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 up 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 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. After the rough processing of the workpiece to complete the blade contour, the workpiece is moved to the 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 claw 6 to collect the debris.
