Description

Technical Field

[0001] The present invention relates to the technical field of flywheel ring gears, and particularly relates to a special machine tool for turning the inner hole of a flywheel ring gear. Background Art

[0002] The flywheel ring gear of an automobile is a key component in an automobile engine. The flywheel ring gear is installed on the outer edge of the flywheel and is usually composed of components such as a ring gear, a shaft, and a gear. The ring gear is the main component and is directly connected to the transmission system. The flywheel is a disc with a large moment of inertia and is installed on the rear flange of the engine crankshaft. The flywheel ring gear can mesh with the drive gear of the starter, and at the same time, the back of the flywheel is a mating surface of the clutch.

[0003] With the rapid development of the automobile industry, the demand for automobile flywheel ring gears is also increasing continuously, and at the same time, the requirements for the machining accuracy and machining efficiency of flywheel ring gears are getting higher and higher. This puts forward higher requirements for various process equipment for machining such parts. Machining its inner hole and chamfering the hole edge is one process, and the machined inner hole is the datum for the subsequent process, which is a key process. At this time, the flywheel ring gear needs to be clamped on the fixture. The existing fixtures usually use clamping blocks to clamp the inner or outer side of the flywheel ring gear during clamping to facilitate the machining of the outer or inner side of the flywheel ring gear. However, the contact position between the clamping block of the fixture and the ring gear is usually planar. When machining the outer ring of the flywheel ring gear, the plane of the clamping block abuts against the inner teeth of the flywheel ring gear, which may cause damage to the teeth of the flywheel ring gear, and thus it is inconvenient for the machining of the flywheel ring gear. Therefore, for the improvement of the existing machine tool, it is particularly important to design a new special machine tool for turning the inner hole of the flywheel ring gear to solve the above technical defects and improve the practicability of the overall machine tool. Summary of the Invention

[0004] The purpose of the present invention is to provide a special machine tool for turning the inner hole of a flywheel ring gear. Through the design of the fixing component, the clamping of the inner and outer sides of the flywheel ring gear can be switched, which is convenient for the machining of the inner side of the inner ring gear. The design of the clamping block can flexibly adapt to flywheel ring gears of different sizes, improving the applicability of the machine tool. At the same time, the filter screen effectively intercepts impurities in the water flow, ensuring the cleanliness of the water flow. The design of the guide frame and the collection tank facilitates the collection and cleaning of impurities, and the cooperation of the mounting rod and the limiting groove realizes the quick and stable installation and disassembly of the filter screen. The design of the compression spring makes the installation process simpler and more labor-saving. The overall design of the mounting rod improves the replacement efficiency of the filter screen and the maintenance convenience of the machine tool to solve the problems put forward in the above background art.

[0020] 2. In the present invention, through the design of the cleaning component, when it is necessary to filter the water flow, the water flow carries impurities through the filter screen. The impurities are intercepted by the filter screen, while the clean water flow continues to flow. When too many impurities accumulate on the filter screen, the second drive motor is started. The second drive motor drives the forward and reverse lead screw to rotate, and then drives the guide frame on the moving frame to displace. The displacement of the guide frame guides the impurities on the filter screen, causing them to fall into the collection groove outside the water storage bin. The filter screen effectively intercepts the impurities in the water flow, ensuring the cleanliness of the water flow. The design of the guide frame and the collection groove facilitates the collection and cleaning of impurities.

[0021] 3.

Release the mounting rod, and the compression spring drives the moving ring and the mounting rod to reset, thereby fixing the filter screen inside the connection frame. When it is necessary to disassemble the filter screen, repeat the above steps, but in the opposite direction. The cooperation of the mounting rod and the limit groove realizes the rapid and stable installation and disassembly of the filter screen. The design of the compression spring makes the installation process more simple and labor-saving. The overall design of the mounting rod improves the replacement efficiency of the filter screen and the maintenance convenience of the machine tool. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work belong to the protection scope of the present invention.

[0033] Embodiment:

[0034] Please refer to Figures 1-9 , the present invention provides a technical solution:

[0035] A special machine tool for turning the inner hole of a flywheel gear ring includes a machine tool main body 1. A connection platform 2 is provided on the top of the machine tool main body 1. A fixing component 3 is provided on the outside of the connection platform 2. A delivery pipe 4 is provided on the top of the machine tool main body 1 and above the connection platform 2. One end of the delivery pipe 4 close to the connection platform 2 is fixedly connected to a connection shell 5. A plurality of spray heads are provided at the bottom of the connection shell 5. A moving platform 6 is slidably connected to the top of the machine tool main body 1 and away from the connection platform 2. A processing head 7 is provided at one end of the moving platform 6 close to the connection platform 2. A water storage bin 8 is opened inside the machine tool main body 1. A filter component 9 is provided inside the water storage bin 8;

[0036] The fixing component 3 is used to fix both sides of the flywheel gear ring. The fixing component 3 is composed of a fixing shell 10, a plurality of moving rods 11, a plurality of connecting rods 12, a plurality of clamping blocks 13 and a plurality of limiting rods 14. The fixing shell 10 is fixedly connected to the inside of the connection platform 2. A plurality of moving rods 11 are all slidably connected to the outside of the fixing shell 10. The connecting rod 12 is fixedly connected to the end of the moving rod 11 away from the fixing shell 10. The clamping block 13 is fixedly connected to the end of the connecting rod 12 extending to the outside of the connection platform 2. The limiting rod 14 is rotatably connected to the outside of the clamping block 13;

[0037] The filter component 9 is used to filter the water flow.

[0038] Further, a guide frame 15 is fixedly connected to the outside of the clamping block 13 and located outside the limiting rod 14. The limiting rod 14 is rotatably connected to the guide frame 15. When the limiting rod 14 contacts the inner side of the flywheel gear ring and rotates under the action of a relative force, the guide frame 15 can guide the limiting rod 14, so that the limiting rod 14 can only perform an arc-shaped displacement with the guide frame 15 as the center of the circle and insert into the tooth groove of the flywheel gear ring, reducing damage to the teeth of the flywheel gear ring. The flywheel gear ring can be fixed by multiple groups of limiting rods 14, so that it is convenient to process the outside of the flywheel gear ring.

[0039] Among them, a fitting groove 16 is formed inside the clamping block 13, and a first buffer strip 17 is fixedly connected to the inside of the fitting groove 16. The first buffer strip 17 is designed in a concave structure. Second buffer strips 18 are fixedly connected to both sides of the fitting groove 16 and located inside the clamping block 13. When the clamping block 13 contacts the flywheel gear ring, the flywheel gear ring contacts the fitting groove 16. Due to the concave structure design of the first buffer strip 17, it can fit the outside of the flywheel gear ring, and cooperate with the second buffer strip 18 to stably fix the flywheel gear ring, which is convenient for processing the inside of the flywheel gear ring.

[0040] Secondly, a gear disk 19 is rotatably connected to the inside of the fixed shell 10. Multiple arc-shaped grooves 20 are formed inside the gear disk 19. The moving rod 11 extends into the arc-shaped groove 20 and is fixedly connected with a guide rod 21. The guide rod 21 is slidably connected to the arc-shaped groove 20. The outside of the gear disk 19 is meshed with a driving gear 22. The driving gear 22 is rotatably connected to the fixed shell 10. The driving end of a first driving motor is fixedly connected to the inside of the driving gear 22. The guide rod 21 is slidably connected to the arc-shaped groove 20. When the arc-shaped groove 20 performs a displacement, it drives the guide rod 21 to perform a displacement, so that the moving rod 11 can perform a displacement. The first driving motor is started to drive the driving gear 22 to rotate, so that the gear disk 19 can rotate, driving multiple arc-shaped grooves 20 to perform an arc-shaped displacement with the center point of the gear disk 19 as the center of the circle, driving the guide rod 21 to perform a displacement, so that the moving rod 11 performs a displacement, driving the connecting rod 12 to perform a displacement, and thus the clamping block 13 can perform a displacement.

[0041] Further, connection seats 23 are fixedly connected to the inside of the fixed shell 10 and outside of multiple sets of moving rods 11. The moving rods 11 are slidably connected to the connection seats 23, and the connecting rods 12 are slidably connected to the connection platforms 2. By slidably connecting the moving rods 11 to the connection seats 23, when the moving rods 11 are displaced, the connection seats 23 can guide the moving rods 11, enabling the moving rods 11 to be displaced stably. By slidably connecting the connecting rods 12 to the connection platforms 2, when the connecting rods 12 drive the clamping blocks 13 to be displaced, the connecting rods 12 can be guided, enabling the connecting rods 12 to be displaced stably.

[0042] Further, the filtering assembly 9 is composed of a connection frame 24, a filter screen 25, a guiding frame 26, and a moving frame 27. The connection frame 24 is located inside the water storage bin 8, the filter screen 25 is located inside the connection frame 24, the guiding frame 26 is slidably connected to the top of the connection frame 24, and the moving frame 27 is slidably connected to the outside of the connection frame 24. The delivery pipe 4 is connected to the water storage bin 8 through a water pump. A through groove is opened at the top of the machine tool main body 1 and on the top of the water storage bin 8. When the water pump is started, the water flow inside the water storage bin 8 can be introduced into the inside of the delivery pipe 4. Through the connection shell 5 and multiple sets of nozzles at the bottom, the water flow is sprayed out and contacts the surface of the flywheel gear ring, performing dust reduction and temperature reduction treatment on the processing area of the flywheel gear ring to prevent affecting the environment for flywheel gear ring processing. When the water flow is introduced into the inside of the water storage bin 8 through the through groove, the filtering assembly 9 can filter the water flow to prevent iron filings carried by the water flow from being introduced into the inside of the delivery pipe 4, damaging the nozzles and affecting the water spraying effect.

[0043] Further, both ends of the bottom of the guiding frame 26 are rotatably connected to first rotating rods 28. The two first rotating rods 28 are connected through a moving block 29. One side of the moving block 29 away from the first rotating rod 28 is rotatably connected to a second rotating rod 30, and the second rotating rod 30 is rotatably connected to the water storage bin 8. The first rotating rod 28 is rotatably connected to the moving block 29. A forward and reverse lead screw 31 is rotatably connected to the inside of the moving frame 27. The moving block 29 axially moves on the outside of the forward and reverse lead screw 31 through balls. A second driving motor is fixedly connected to the outside of the moving frame 27, and the driving end of the second driving motor is fixedly connected to the forward and reverse lead screw 31. By rotatably connecting both the first rotating rod 28 and the second rotating rod 30 to the moving block 29, when the second driving motor is started, it drives the forward and reverse lead screw 31 to rotate, enabling the two moving blocks 29 to be displaced, driving the first rotating rod 28 and the second rotating rod 30 to be displaced, and enabling the guiding frame 26 to be displaced. When impurities carried by the water flow fall on the top of the filter screen 25, the displacement of the guiding frame 26 can guide the impurities.

[0044] Furthermore, vibration motors are fixedly connected to the four sides of the top of the connection frame 24. A collection groove 32 is formed on the outer side of the water storage tank 8. Damping springs 33 are fixedly connected to the four sides of the bottom of the connection frame 24. Starting the vibration motors and cooperating with the damping springs 33 can drive the connection frame 24 to vibrate, driving the impurities on the top of the filter net 25 to vibrate, vibrating the water flow on the surface of the impurities, and preventing the water flow from being introduced into the collection groove 32 when the impurities are introduced into the collection groove 32, resulting in water waste. Two sets of sleeves 34 are fixedly connected to the front end of the top of the connection frame 24. An installation rod 35 is slidably connected to the inside of the sleeve 34. The filter net 25 is connected to the installation rod 35 through a limit groove. A moving ring 36 is fixedly connected to the outer side of the installation rod 35 and inside the sleeve 34. A compression spring 37 is fixedly connected to the top of the moving ring 36 and on the outer side of the installation rod 35. When the guide frame 26 guides the impurities, the impurities can be introduced into the collection groove 32. The impurities can be collected through the collection groove 32 for convenient treatment. The water flow is introduced into the water storage tank 8 and can be introduced into the inside of the conveying pipe 4 through a water pump. When the surface of the filter net 25 is severely worn after long-term use, affecting its use, the installation rod 35 is pulled out of the limit groove, and the limit connection with the filter net 25 is disconnected, enabling the filter net 25 to be displaced, and thus displaced out of the connection frame 24 to disassemble the filter net 25. A new filter net 25 is placed inside the connection frame 24. The compression spring 37 drives the moving ring 36 to displace, causing the installation rod 35 to displace, and the installation rod 35 is displaced into the limit groove, thereby enabling the installation of the filter net 25.

[0045] In this embodiment, the implementation scenario is specifically as follows: During actual use, the flywheel ring gear is placed outside the connecting table 2. When machining the inner side of the flywheel ring gear is required, the first driving motor is started to drive the driving gear 22 to rotate, enabling the gear disk 19 to rotate, driving multiple arc-shaped grooves 20 to perform arc-shaped displacement with the center point of the gear disk 19 as the center of the circle, driving the guide rod 21 to displace, enabling the moving rod 11 to displace, driving the connecting rod 12 to displace, and thus enabling the clamping block 13 to displace. The multiple clamping blocks 13 are displaced towards the center of the connecting table 2, causing the clamping block 13 to contact the outer side of the flywheel ring gear. When the clamping block 13 contacts the flywheel ring gear, the flywheel ring gear contacts the fitting groove 16. Through the concave structure design of the first buffer strip 17, it can fit the outer side of the flywheel ring gear, and in cooperation with the second buffer strip 18, it can stably fix the flywheel ring gear, facilitating the machining of the inner side of the flywheel ring gear. The displacement moving table 6 drives the machining head 7 to displace, enabling the machining head 7 to machine the flywheel ring gear. When machining the outer side of the flywheel ring gear is required, the flywheel ring gear is placed outside the multiple clamping blocks 13, and the multiple clamping blocks 13 displace towards the end away from the center of the connecting table 2, causing the limiting rod 14 to contact the inner side of the flywheel ring gear. When the limiting rod 14 contacts the inner side of the flywheel ring gear and rotates under the relative force, the guide frame 15 can guide the limiting rod 14, enabling the limiting rod 14 to only perform arc-shaped displacement with the guide frame 15 as the center of the circle and insert into the tooth groove of the flywheel ring gear, reducing damage to the teeth of the flywheel ring gear. The flywheel ring gear can be fixed through the multiple limiting rods 14, thereby facilitating the machining of the outer side of the flywheel ring gear. When machining the flywheel ring gear, the water pump is started, and the water flow inside the water storage bin 8 can be introduced into the inside of the conveying pipe 4. Through the connecting shell 5 and multiple nozzles at the bottom, the water flow is sprayed out and contacts the surface of the flywheel ring gear, performing dust reduction and temperature reduction treatment on the machining area of the flywheel ring gear to prevent affecting the environment for machining the flywheel ring gear. The water flow is introduced into the inside of the water storage bin 8 through the through groove, and the water flow is filtered by the filter screen 25, causing impurities to fall on the top of the filter screen 25. The water flow is introduced to the bottom end inside the water storage bin 8 for recycling. When too many impurities accumulate on the top plate of the filter screen 25, the second driving motor is started to drive the forward and reverse screw rod 31 to rotate, enabling the two moving blocks 29 to displace, driving the first rotating rod 28 and the second rotating rod 30 to displace, and enabling the guide frame 26 to displace. When the water flow carries impurities and falls on the top of the filter screen 25, the displacement of the guide frame 26 can guide the impurities. When the guide frame 26 guides the impurities, the impurities can be introduced into the collection groove 32, and the impurities can be collected through the collection groove 32 for convenient treatment. When the filter screen 25 is used for a long time and there is significant wear on the surface, affecting its use, the installation rod 35 is pulled out of the limiting groove, disconnecting the limiting connection with the filter screen 25, enabling the filter screen 25 to displace.Thus, it is displaced out of the inside of the connection frame 24, the filter screen 25 is disassembled, a new filter screen 25 is placed inside the connection frame 24, the compression spring 37 drives the moving ring 36 to displace, so that the mounting rod 35 is displaced, and the mounting rod 35 is displaced into the limiting groove, so that the filter screen 25 can be installed. Compared with the existing machine tools, the overall practicability of the machine tool can be improved through the design of the present invention.

[0046] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
