Description

Technical Field

[0001] The present invention relates to the technical field of blade processing equipment, and in particular to a device for optimizing the surface roughness of titanium-aluminum single crystal blades. Background Art

[0002] The blades used in aircraft engines are the core components for achieving energy conversion. They convert the internal energy of fuel into mechanical energy by compressing and expanding air, thereby driving the engine. Blades made of titanium aluminum single crystals achieve a combination of high strength and high plasticity, meeting the adaptability requirements of aircraft engines to stress environments. During their production process, polishing equipment is often required to optimize the surface of the blades to avoid excessive surface roughness of the blades affecting subsequent use.

[0003] Existing polishing equipment that can process blades often uses abrasive flow polishers, which can perform high-precision processing on the workpiece surface by carrying abrasives through fluid media to achieve micron-level surface finish. However, when polishing the blade surface, some existing abrasive flow polishers cannot be fully polished because the blades are placed inside the abrasive flow polisher or even fixed inside the abrasive flow polisher and cannot be moved by external force. This requires improvement. Summary of the Invention

[0004] The purpose of the present invention is to provide a device for optimizing the surface roughness of titanium-aluminum single crystal blades to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a device for optimizing the surface roughness of a titanium-aluminum single crystal blade, comprising a body and a mounting cylinder disposed within the body, and further comprising a polishing assembly disposed within the mounting cylinder, the polishing assembly comprising: A grinding cylinder, wherein a hidden groove is provided on the outer wall of the grinding cylinder, a magnetic sleeve for adjusting the position of the blade is movably placed in the hidden groove, and a storage component for placing the blade and abrasive used for polishing is movably placed in the grinding cylinder; The driving assembly is used to drive the magnetic sleeve to rotate.

[0006] The storage assembly includes a storage tube, in which a plurality of splicing rings for supporting blades are installed. Adjacent splicing rings are connected by a plurality of connecting rods to prevent blades from falling. The splicing rings are fixedly installed in the storage tube by a plurality of connecting blocks.

[0007] The polishing assembly also includes a linkage plate rotatably mounted on the inner wall of the bottom end of the mounting tube, a fixed block is mounted on the linkage plate, an arc-shaped guide plate for following the displacement of the magnetic sleeve is mounted on the fixed block, a fixing ring is mounted on the outer wall of the magnetic sleeve, and an L-shaped toggle block for toggling the arc-shaped guide plate to generate displacement is provided on the outer wall of the fixing ring.

[0008] The machine body is provided with an abrasive conveying assembly for conveying and recovering abrasives used for polishing. The abrasive conveying assembly includes a stirring tank capable of processing recycled abrasives. The stirring tank is provided with a discharge pipe for conveying abrasives. One end of the discharge pipe is connected to a docking bell mouth for docking with a storage cylinder. The stirring tank is also provided with a feed pipe for recovering abrasives. One end of the feed pipe is provided with a collection bell mouth for connecting to the rear side wall of the grinding cylinder.

[0009] The side wall of the mixing tank is connected to the machine body via an electric push rod, which is used to change the position of the mixing tank to facilitate the removal of the blades.

[0010] The driving assembly includes a convex block, a rotating motor is mounted on the convex block, and a belt is sleeved between the output shaft of the rotating motor and the magnetic sleeve.

[0011] Two limiting rings are movably attached to the outer wall of the belt for limiting its movable space, and the limiting rings are fixedly installed on the outer wall of the magnetic sleeve.

[0012] Two fixing brackets are fixedly mounted on the outer wall of the grinding cylinder, and the position of the grinding cylinder is fixed by the two fixing brackets being fixed in the mounting cylinder.

[0013] The top plate of the linkage plate adopts an inclined slope with a high back and a low front, and an electric heating plate for heating the abrasive in the feed pipe is mounted on the top of the linkage plate.

[0014] The bottom ends of the fixing frames are each provided with a groove for squeezing and deforming the feed pipe.

[0015] The bottom end of the linkage plate is connected to a connecting plate, and a rotating shaft is fixedly installed on the connecting plate. The rotating shaft is rotatably installed on the inner wall of the bottom end of the installation cylinder.

[0016] The bottom end of the mixing tank is provided with a plurality of rollers for assisting the electric push rod to push the mixing tank to move.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The present invention starts a rotating motor so that the storage cylinder can rotate along with the magnetic sleeve. During the rotation of the storage cylinder, the splicing ring and the connecting rod, the local position of the blade placed in the two connecting rods is affected by the connecting rods during the rotation and is separated from the contact therewith, so that the contact position of the blade with the splicing ring and the connecting rod is changed during the polishing process, and it is avoided that the contact position of the blade with the inner wall of the abrasive flow polisher cannot be fully polished due to difficulty in adjustment.

[0018] The L-shaped toggle block rotates synchronously with the magnetic sleeve, driving the arc-shaped guide plate to move upward during the rotation process. At this time, the fixed block and the linkage plate rotate synchronously, causing the linkage plate to tilt. The top end of the feed pipe and the fixed frame will be partially fitted, causing the feed pipe to deform. The tilted and deformed feed pipe accelerates the flow rate of the abrasive inside it, thereby increasing the efficiency of abrasive recycling.

[0019] By adopting a linkage plate with an inclined top plate and heating the abrasive in the feed pipe through the electric heater on the top of the linkage plate, the abrasive in the feed pipe is heated to prevent the rubber, one of the components of the abrasive, from solidifying due to low temperature.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figures 1 to 10 The present invention provides a technical solution: a surface roughness optimization processing device for titanium-aluminum single crystal blades, comprising a body 1, a mounting cylinder 2 placed in the body 1, four translational slides provided in the body 1, slides slidably installed in the four translational slides, the rear back of the slides are provided with plug-in rods, the rear back inner wall of the translational slide is provided with plug-in grooves that match the diameter of the plug-in rods, by inserting the plug-in rods into the plug-in grooves, the slides can be conveniently fixed and installed in the translational slides for use, the four slides are fixedly installed on the outer wall of the mounting cylinder 2, when the internal parts of the body 1 need to be repaired and cleaned later, the mounting cylinder 2 can be conveniently withdrawn from the body 1, a polishing assembly 3 for polishing the blades is provided in the mounting cylinder 2, the polishing assembly 3 includes a grinding cylinder 4 for facilitating the passage of abrasives used for polishing, and the grinding Two fixing frames 5 for connecting to the inner wall of the mounting cylinder 2 are fixedly installed on the outer wall of the cylinder 4. The grinding cylinder 4 and the mounting cylinder 2 are fixedly connected into a whole through the fixing frames 5, and the fixing frames 5 are composed of a circular ring and two horizontal plates. The two horizontal plates are fixedly installed on the outer wall of the circular ring, and a groove is provided at the bottom end of the circular ring. The feed pipe 30, which is one of the components of the abrasive conveying assembly 24, passes through the fixing frame 5 through the groove to avoid the bottom end of the fixing frame 5 directly fitting the feed pipe 30, resulting in the feed pipe 30 being unable to follow the linkage plate 15 to move upward, and in the process of the linkage plate 15 moving upward, the feed pipe 30 will be driven to partially fit the inner wall of the groove at the bottom end of the circular ring, which is one of the components of the fixing frame 5, so that the feed pipe 30 will be partially deformed in the process of following the linkage plate 15 to move upward and tilt, and the viscous abrasive will be squeezed and accelerated.

[0033] A hidden groove 6 is provided on the outer wall of the grinding cylinder 4, and the hidden groove 6 is located between the two fixing frames 5. A magnetic sleeve 7 for driving the blade to move is movably provided on the outer wall of the grinding cylinder 4. The blade is driven to move on the outer wall of the grinding cylinder 4 by the magnetic sleeve 7, so that the contact position between the blade and the inner wall of the abrasive flow polishing machine does not change for a long time, resulting in that the local part of the blade is not fully polished by the abrasive particles, and the magnetic sleeve 7 is placed in the hidden groove 6. The grinding cylinder 4 is made of a non-ferromagnetic alloy (such as an aluminum-based alloy) in the prior art. The magnetic sleeve 7 is composed of a strong magnetic strip and a cylinder in the prior art. The inner wall of the cylinder is provided with a mounting groove. Groove, a strong magnetic strip is installed in the installation groove, and the strong magnetic strip is made of neodymium iron boron magnet with performance grade N42 in the existing technology. The grinding cylinder 4 made of non-ferromagnetic alloy can avoid the magnetic sleeve 7 from rotating on the outer wall of the grinding cylinder 4. The magnetic sleeve 7 will be directly adsorbed on the outer wall of the grinding cylinder 4 and cannot rotate. The abrasive used for polishing in the abrasive flow polishing machine needs to be composed of a mixture of rubber and silicon carbide. Silicon carbide and rubber cannot be adsorbed by the magnetic sleeve 7, so as to avoid the situation in which the abrasive used for polishing in the abrasive flow polishing machine is adsorbed due to the rolling of the magnetic sleeve 7 during use, thereby causing the polishing effect of the blade to deteriorate.

[0034] A fixing ring 8 for following its rotation is fixedly installed on the outer wall of the magnetic sleeve 7, and an L-shaped toggle block 9 for driving the linkage plate 15 to move upward is fixedly installed on the front end surface of the fixing ring 8. A placement groove is provided on the side wall of the front end surface of the mounting cylinder 2, and a rotating shaft 16 is rotatably installed in the placement groove. A connecting plate 17 is fixedly installed on the top of the rotating shaft 16, and a linkage plate 15 for supporting the feed pipe 30 is installed on the top of the connecting plate 17, and the side wall of the bottom end of the linkage plate 15 adopts an arc shape that fits the inner wall of the mounting cylinder 2, and the linkage plate 15 is fixedly installed on the top of the connecting plate 17. The top of the plate 15 adopts a six-degree slope from back to front, and the slope is high at the back and low at the front. The top of the linkage plate 15 is mounted with a heating plate, which is connected to the existing power supply through a line. The feed pipe 30 is fixedly mounted on the top of the heating plate. The heating plate generates heat after being powered on, and heats the abrasive in the feed pipe 30 to prevent the rubber, one of the components of the abrasive, from solidifying due to too low a temperature. The top of the linkage plate 15 is fixed with a fixing block 18 just below the L-shaped toggle block 9. The front end surface of the fixed block 18 is fixedly mounted with an arc-shaped guide plate 19, and the arc-shaped guide plate 19 is in the active path of the L-shaped toggle block 9. When the fixed ring 8 rotates clockwise following the magnetic sleeve 7, the L-shaped toggle block 9 on the fixed ring 8 will contact the bottom side wall of the arc-shaped guide plate 19, and in the process of continuous rotation of the L-shaped toggle block 9, the arc-shaped guide plate 19 will be driven to move upward. At this time, the linkage plate 15 fixedly connected to the arc-shaped guide plate 19 by the fixed block 18 will rotate upward through the rotating shaft 16, which not only increases the rotation speed, but also increases the rotation speed. The feed pipe 30 is inclined at the portion on the linkage plate 15 to accelerate the flow rate of the abrasive in the feed pipe 30. After the L-shaped toggle block 9 continues to rotate and breaks away from the contact with the arc guide plate 19, the arc guide plate 19 and the linkage plate 15 move downward and hit the inner wall of the bottom end of the mounting cylinder 2, causing the linkage plate 15 to vibrate, thereby preventing the abrasive in the feed pipe 30 at the top of the linkage plate 15 that is not heated by the electric heater from sticking to the inner wall of the feed pipe 30, causing the feed pipe 30 to be blocked after long-term use.

[0035] Two limiting rings 10 for limiting the activity space of the belt 13 are fixedly installed on the outer wall of the magnetic sleeve 7. A driving assembly is fixedly installed on the inner wall of the top end of the mounting cylinder 2. The driving assembly includes a protrusion 11 fixedly installed on the inner wall of the top end of the mounting cylinder 2. The front end face of the protrusion 11 is provided with a groove. A rotating motor 12 is installed in the groove. The output shaft of the rotating motor 12 extends out of the groove. The output shaft of the rotating motor 12 and the outer wall of the magnetic sleeve 7 are jointly covered with a belt 13. A groove matching the width of the belt 13 is provided on the outer wall of the output shaft of the rotating motor 12. The belt 13 is placed in the groove, and the part of the belt 13 on the outer wall of the magnetic sleeve 7 is between the two limiting rings 10. The belt 13 is driven to rotate by the rotating motor 12. At this time, the magnetic sleeve 7 rotates synchronously, so that the fixing ring 8 and the L-shaped toggle block 9 rotate with it, which is convenient for driving the linkage plate 15 to move.

[0036] A storage assembly 14 for placing blades to be ground is movably installed in the grinding cylinder 4. The storage assembly 14 includes a storage cylinder 20 for facilitating the passage of abrasives. The storage cylinder 20 can be designed to be the same length as the grinding cylinder 4 according to actual use requirements. The outer diameter of the storage cylinder 20 is the same as the inner diameter of the grinding cylinder 4. Because the surface of the grinding cylinder 4 is provided with a hidden groove 6 and in order to facilitate the magnetic sleeve 7 to drive the storage cylinder 20 to rotate during the rotation process, the shell of the grinding cylinder 4 needs to be designed to be thinner. At this time, the storage cylinder 20 can replace the grinding cylinder 4 for the transmission of abrasives, and because the storage cylinder 20 can be removed from the grinding cylinder 4, during long-term use, if the inner wall of the storage cylinder 20 is excessively polished by the abrasive, it can be replaced in time to avoid the more troublesome disassembly and replacement of the grinding cylinder 4.

[0037] Several splicing rings 21 for holding blades are provided in the storage barrel 20. The outer wall of the splicing ring 21 is fixedly connected to the inner wall of the storage barrel 20 by several connecting blocks 23. When the storage barrel 20 rotates following the magnetic sleeve 7, the splicing ring 21 is driven to rotate by the connecting blocks 23. Adjacent splicing rings 21 are fixedly connected by several connecting rods 22. The blades are placed in the several splicing rings 21, and the connecting rods 22 prevent the blades from falling from the gaps between the adjacent splicing rings 21. The middle section of the outer wall of 20 is set as an inner groove, in which an iron sheet is fixedly installed. When the magnetic sleeve 7 is rotated by the belt 13, the strong magnetic strip on the magnetic sleeve 7 will attract the iron sheet and rotate synchronously during the rotation, causing the storage barrel 20 to rotate. After the rotation, the splicing ring 21 in the storage barrel 20 is displaced. At this time, the blade at the top of the splicing ring 21 will be affected and deviated. The contact part of the blade with the splicing ring 21 or the connecting rod 22 will be exposed and fully polished by the abrasive.

[0038] The machine body 1 is provided with an abrasive conveying assembly 24 for guiding the movement of the abrasive used for the polishing blade. The abrasive conveying assembly 24 includes an electric push rod 26 fixedly mounted on the front end surface of the machine body 1. The front end surface of the electric push rod 26 is provided with a stirring tank 25 for storing the abrasive. The bottom end of the stirring tank 25 is provided with a plurality of rollers for assisting the electric push rod 26 in pushing the stirring tank 25 to move. The stirring tank 25 is provided with an agitator, which consists of a rotating motor and a stirring fan blade. The stirring fan blade is fixedly mounted on the top end of the output shaft of the rotating motor. The stirring tank 25 is also provided with an electric heating rod for heating the rubber in the abrasive to prevent it from solidifying. The stirring tank 25 is also provided with an abrasive conveying pump for conveying the abrasive. The 304 stainless steel cast pump body semi-open impeller stainless steel centrifugal pump in the prior art can be used, and the abrasive conveying pump is not in the range of movement of the stirring fan blade. The discharge port of the abrasive conveying pump is connected to a discharge pipe 27. The end of the discharge pipe 27 not connected to the abrasive conveying pump passes through the top plate of the stirring tank 25 and is connected to a docking horn The bell mouth 28 is connected to the back of the bell mouth 28 and is tightly fitted with the front end of the storage cylinder 20. A feeding pipe 30 for recovering the abrasive used after polishing the blades is also provided in the mixing tank 25. One end of the feeding pipe 30 passes through the top plate of the mixing tank 25 and extends into the inner cavity of the mixing tank 25. The other end is connected to the collecting bell mouth 29. A retaining plate is installed on the back of the grinding cylinder 4. The retaining plate is provided with a number of through holes for the abrasive to pass through. The collecting bell mouth 29 is fixedly installed on the back of the retaining plate. The abrasive is collected when it is flowing. After the blades are polished, they will flow into the collecting bell mouth 29 and into the feed pipe 30, and then flow back to the stirring tank 25 through the feed pipe 30. The feed pipe 30 is composed of a silicone rubber tube and a stainless steel corrugated hose. The silicone rubber tube and the stainless steel corrugated hose are connected by threaded assembly. This is a common existing technology and will not be described in detail here. The feed pipe 30 at the top of the electric heating plate on the linkage plate 15 is made of a silicone rubber tube, which not only has high temperature resistance, but also has a deformation effect after being heated.

[0039] When the present invention is in use, the electrical appliance on the body 1 is started by an external power supply, the blade to be micro-processed is placed in the splicing ring 21, and the blade is partially placed in the gap between the two adjacent connecting rods 22, the splicing ring 21 and the storage cylinder 20 are placed in the grinding cylinder 4, and the electric push rod 26 is used to push the mixing tank 25 to move to its back until the docking bell mouth 28 partially extends into the grinding cylinder 4 and fits tightly with the storage cylinder 20, and the abrasive in the mixing tank 25 is transported into the storage cylinder 20 through the discharge pipe 27 and the docking bell mouth 28 by the abrasive delivery pump, and in the process of flow, the abrasive in the storage cylinder is The blades in 20 are polished, and the abrasive flowing through the blades is recovered into the mixing tank 25 through the collecting bell mouth 29 and the feeding pipe 30. During the polishing process, the operation of the abrasive delivery pump is temporarily stopped, and the operation of the rotary motor 12 is controlled to rotate the magnetic sleeve 7 on the outer wall of the grinding cylinder 4. At this time, the strong magnetic strips on the magnetic sleeve 7 absorb the iron sheet on the surface of the storage cylinder 20 through the grinding cylinder 4, so that the storage cylinder 20 can rotate with the magnetic sleeve 7. At this time, the blades in the storage cylinder 20 are filled with abrasive except for the bottom end that contacts the splicing ring 21 and the connecting rod 22. The barrel 20, the splicing ring 21 and the connecting rod 22 will be affected by the abrasive during the rotation process, causing the blade to shift in position, that is, the local position of the blade placed between the two connecting rods 22 will be separated from the contact therebetween due to the influence of the connecting rod 22 during the rotation process, so that the contact position of the blade with the splicing ring 21 and the connecting rod 22 can be changed during the polishing process. In addition, during the polishing process, the fixing ring 8 and the L-shaped toggle block 9 on the outer wall of the magnetic sleeve 7 rotate synchronously. The L-shaped toggle block 9 will contact the arc guide plate 19 during the rotation process, and the arc guide plate 19 will be driven by the bottom plate shape of the arc guide plate 19. 9 moves upward, at this time the fixed block 18 and the linkage plate 15 rotate synchronously, causing the linkage plate 15 to tilt, and the feed pipe 30 located at the top thereof tilts synchronously, and at the same time the top of the feed pipe 30 and the fixed frame 5 are partially fitted, causing the feed pipe 30 to deform, and the L-shaped toggle block 9 is disconnected from the arc-shaped guide plate 19 during continuous rotation, and the linkage plate 15 rotates downward through the rotating shaft 16 and hits the inner wall of the bottom end of the mounting cylinder 2, generating vibration, thereby accelerating the flow rate of the abrasive inside the tilted and deformed feed pipe 30, thereby accelerating the efficiency of abrasive recycling.
