Description

Technical Field

[0001] This application relates to the field of installation equipment technology, and in particular to a high-speed chip cutting tool for metal parts. Background Technology

[0002] Metal parts are widely used in modern manufacturing, and their machining accuracy and efficiency are crucial. High-speed cutting technology is the main means to improve metal processing efficiency, but during high-speed cutting, the high-speed friction between the tool and the workpiece generates a large amount of heat and metal chips.

[0003] When machining certain materials (such as metals with good toughness), the chips produced by high-speed cutting are often long or spiral-shaped. These hot and continuous chips have high flexibility and are very easy to quickly wrap around the tool holder or spindle under the combined action of centrifugal force and cutting force.

[0004] The entanglement of chips can cause a series of serious problems: First, the entangled chips can scratch the machined surface of the workpiece, resulting in a decrease in the surface finish and dimensional accuracy of the parts; second, the accumulation of chips can hinder the coolant from reaching the cutting area, causing local overheating of the tool, aggravating tool wear, and even causing tool burning or chipping, which seriously shortens the tool's service life; in addition, the entangled chips may also cause the machine tool to stop, requiring manual cleaning and interrupting the automated production process.

[0005] Currently, the industry mainly relies on high-pressure coolant to spray onto the cutting area, attempting to break and flush away chips through the impact force of the coolant. However, at extremely high speeds, chip generation is very rapid, and the obstruction of the tool itself may prevent the coolant from accurately targeting the root cause of chip entanglement. For highly viscous and tough chips, relying solely on fluid impact force is often insufficient to effectively prevent them from entangled on the tool surface, resulting in low reliability of chip removal. Therefore, this invention proposes a high-speed chip machining tool for metal parts to address the shortcomings of the existing technology. Utility Model Content

[0006] The purpose of this application is to provide a high-speed chip cutting tool for metal parts, which aims to improve the problem that the length of the curtain wall cannot be adjusted according to different situations.

[0007] This application provides a high-speed chip cutting tool for machining metal parts, which adopts the following technical solution: The above technical solution includes a base, a docking mechanism, and a cutting tool; the docking mechanism is installed on the base to hold the cutting tool.

[0008] It also includes a dander removal mechanism; the dander removal mechanism includes a fixed plate, a motor, a turntable, a connecting rod, a dander scraper ring, and a limit assembly.

[0009] A fixed plate is fixedly connected to the base. A motor is fixedly connected to the fixed plate, and the motor's output shaft is fixedly connected to a turntable. A drive shaft is eccentrically and rotatably connected to the turntable, and a sliding sleeve is connected to the end of the drive shaft, which drives a connecting rod. The limiting assembly includes a fixed block, which is fixed to the outer wall of the fixed plate by a pin, and the connecting rod passes through and is slidably connected to the fixed block. A connecting plate is fixedly connected to the end of the connecting rod, and a chip scraper ring is fixedly connected to the bottom of the connecting plate, the chip scraper ring surrounding the outer circumference of the cutting tool.

[0010] Preferably, during cutting, the motor drives the turntable to rotate, the eccentric transmission shaft drives the sliding sleeve and connecting rod, and the connecting rod moves under the restriction of the limiting component, driving the scraper ring to scrape off the chips on the surface of the cutting tool through the connecting plate. The machine tool's fluid supply system connects to the tool via the spindle and base, and the docking mechanism connects the fluid to the tool. The fluid flows through the tool to cool it and flush away the chips. The sealing ring prevents leakage, ensuring cutting accuracy and tool life. By adopting the above technical solution, the limiting component also includes a limiting block, which is fixedly connected to the end of the connecting rod away from the connecting plate. This arrangement is used to prevent the connecting rod from coming off the fixed block, thereby improving the safety of reciprocating motion.

[0011] Preferably, during cutting, the motor drives the turntable to rotate, and the eccentric transmission shaft drives the sliding sleeve and connecting rod. The connecting rod moves horizontally under the limitation of the fixed block, and its tail limit block prevents it from falling out, improving the safety of reciprocating motion. The connecting plate drives the scraper ring to scrape off the chips. The liquid supply system connects to the tool through the spindle and base, and the docking mechanism. The coolant cools and flushes away chips, and the sealing ring prevents leakage, ensuring accuracy and tool life. By adopting the above technical solution, the docking mechanism includes a housing fixed inside the base and a plug for connecting the cutting tool. The plug is detachably inserted into the housing, forming the basis for coolant delivery and cutting tool fixation.

[0012] Preferably, in the docking mechanism, the outer shell inside the base is detachably plugged into the plug that connects the tool, which not only provides a fixed base for the tool, but also forms a coolant delivery channel, realizing the dual functions of tool installation and fixation and coolant transmission, and is an important connecting part of the overall structure; By adopting the above technical solution, the docking mechanism also includes a limiting sleeve, a steel ball, and a second spring. The outer wall of the outer shell has a radial through hole, the steel ball is housed in the radial through hole, the limiting sleeve is slidably sleeved on the outer wall of the outer shell, and the second spring surrounds the outer wall of the outer shell and abuts against the limiting sleeve, which is used to drive the limiting sleeve to return to its axial position. The radial locking of the steel ball is controlled by the axial movement of the limiting sleeve.

[0013] Preferably, in the docking mechanism, the steel ball inside the radial through hole on the outer wall of the outer shell is controlled by a limiting sleeve that is slidably sleeved on the outer shell; the spring surrounds the outer shell and abuts against the limiting sleeve, driving it to return to its axial position. By moving the limiting sleeve axially, the radial locking state of the steel ball is controlled, ensuring a stable connection between the plug and the outer shell. By adopting the above technical solution, the docking mechanism also includes a piston and a spring. Pistons are provided axially inside the outer shell and the plug. The spring is located between two opposing pistons and is used to automatically close the flow channel in the non-docked state and to be compressed to open the flow channel during docking.

[0014] Preferably, pistons are provided in both the outer shell and the plug of the docking mechanism. When not docking, the spring between the two pistons automatically pushes the piston to close the flow channel; when docking, the spring is compressed and the piston retracts to open the flow channel, realizing the automatic on / off of coolant delivery and ensuring that the flow channel state before and after docking is controllable. By adopting the above technical solution, the docking mechanism also includes a sieve plate, which is horizontally arranged inside the plug and located in the flow channel behind the piston. It is used to filter impurities in the coolant and prevent impurities from clogging the cooling channels inside the tool.

[0015] Preferably, a transverse sieve plate is provided inside the plug of the docking mechanism and in the flow channel behind the piston, which can filter impurities in the coolant, prevent impurities from entering and clogging the internal cooling channel of the tool, and ensure smooth flow of coolant and tool cooling effect. By adopting the above technical solution, the docking mechanism also includes a sealing ring, which is set in an annular groove on the outer wall of the plug. The sealing ring is used to seal the gap between the outer wall of the plug and the inner wall of the housing after the plug is inserted into the housing, so as to prevent high-pressure coolant leakage.

[0016] Preferably, a sealing ring is provided in the annular groove on the outer wall of the plug of the docking mechanism. When the plug is inserted into the outer shell, the sealing ring can seal the gap between the inner and outer walls of the two. By adopting the above technical solution, the fixed plate has an internal cavity for the turntable to rotate, and the motor output shaft passes through the fixed plate and connects to the turntable. This design allows the main body of the turntable to be housed in the fixed plate, making the overall structure more compact.

[0017] Preferably, the fixed plate has a cavity inside for the turntable to rotate, and the motor output shaft passes through the fixed plate and is connected to the turntable, so that the main body of the turntable is housed in the cavity. This satisfies the turntable's rotation requirements while significantly reducing the overall structural space occupied, achieving a compact layout design. In summary, this application includes at least one of the following beneficial technical effects: 1. In this utility model, by setting up a mechanical chip removal mechanism driven by a motor, the rotary motion is converted into the reciprocating linear motion of the chip scraper ring by using a turntable, connecting rod and limiting components. This solves the problem in the prior art that chips are easy to wrap around the surface of the cutting tool and are difficult to remove during high-speed cutting. It achieves the technical effect of actively and forcibly scraping the surface of the cutting tool, effectively preventing chip wrapping, and ensuring the stability and accuracy of processing.

[0018] 2. In this utility model, by setting a docking mechanism that uses steel balls, springs and limiting sleeves, and an automatic opening and closing flow channel with pistons and springs inside, the problems of cumbersome tool replacement and poor external cooling effect leading to serious heat accumulation in the tool are solved. It achieves the technical effect of both quick tool installation and removal and automatic connection of high-pressure internal cooling channel to achieve efficient cooling of the cutting area.

[0019] 3. In this utility model, by integrating the active scraping chip removal mechanism with the quick-connect internal cooling mechanism, the problem of low efficiency of a single chip removal or cooling method is solved. It achieves the dual functions of coordinated chip removal by mechanical scraping and high-pressure flushing, as well as efficient cooling. The overall integration is high, automation is strong, and the technical effect of significantly improving the comprehensive performance of high-speed machining and the service life of the cutting tool is significantly enhanced. 4. In this utility model, by setting a limiting component in the chip removal mechanism to constrain the movement of the connecting rod, and by filtering the coolant through a sieve plate, the problems of easy swaying of mechanical movement and easy blockage of cooling channels are solved. This achieves the technical effects of stable overall structure operation, precise and reliable chip removal action, less clogging of the cooling system, and extended overall service life of the equipment.

[0021] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0022] Example: A high-speed chip cutting tool for machining metal parts, such as Figure 1 and Figure 2 As shown, this embodiment includes a base 1, a docking mechanism 2 mounted on the base 1 for clamping the cutting tool 4, and a chip removal mechanism 3 for removing chips from the surface of the cutting tool 4. The base 1 serves as the mounting base for the entire device, providing stable installation and support for the docking mechanism 2 and the chip removal mechanism 3. Specifically, a high-speed chip cutting tool for metal parts includes a base 1, which provides a stable mounting support for the entire device and ensures the stability of the overall structure during the cutting process. A docking mechanism 2 is mounted on the base 1 to hold the cutting tool 4. The docking mechanism 2 can realize the rapid and accurate docking of the cutting tool 4 and can also cooperate with the flow of coolant to cool it down. A chip removal mechanism 3 is used to remove chips from the surface of the cutting tool 4. The chip removal mechanism 3 can efficiently scrape and crush the chips to avoid chip entanglement affecting the cutting accuracy and tool life.

[0023] like Figure 1 and Figure 3 As shown, the dandruff removal mechanism 3 includes a fixed plate 39, a motor 38, a turntable 35, a transmission shaft 36, a sliding sleeve 34, a connecting rod 32, a connecting plate 31, a dandruff scraping ring 37, and a limiting component 33. The fixed plate 39 is fixedly connected to the base 1, and the motor 38 is fixedly connected to the fixed plate 39. The output shaft of the motor 38 passes through the fixed plate 39 and is fixedly connected to the turntable 35. The fixed plate 39 has an internal cavity for the turntable 35 to rotate, and the motor 38 drives the turntable 35 to rotate within the cavity. Specifically, the chip removal mechanism 3 includes a fixed plate 39, a motor 38, a turntable 35, a transmission shaft 36, a sliding sleeve 34, a connecting rod 32, a connecting plate 31, a chip scraper ring 37, and a limiting component 33. The fixed plate 39 is securely fixed to the base 1 to ensure installation stability. The motor 38 is securely fixed to the fixed plate 39. The output shaft of the motor 38 passes through the fixed plate 39 and is tightly fixed to the turntable 35. The fixed plate 39 has an internal cavity adapted to the rotation of the turntable 35. The motor 38 drives the turntable 35 to rotate smoothly in the cavity, providing stable power for subsequent chip removal.

[0024] During the operation of the dandruff removal mechanism 3, a drive shaft 36 is eccentrically and rotatably connected to the turntable 35. A sliding sleeve 34 is connected to the end of the drive shaft 36, and the sliding sleeve 34 drives the connecting rod 32. To ensure that the connecting rod 32 performs stable linear reciprocating motion, a limiting component 33 is provided to limit the movement trajectory of the connecting rod 32. The limiting component 33 includes a fixing block 331, which is fixed to the outer wall of the fixing plate 39 by a pin 332. The connecting rod 32 passes through and is slidably connected to the fixing block 331. This arrangement limits the rotation of the turntable 35. The motion is converted into the reciprocating linear motion of the connecting rod 32. The limiting component 33 also includes a limiting block 333, which is fixedly connected to the end of the connecting rod 32 away from the connecting plate 31 to prevent the connecting rod 32 from coming off the fixed block 331, thereby ensuring the reliability of the motion. The end of the connecting rod 32 is fixedly connected to the connecting plate 31, and the bottom of the connecting plate 31 is fixedly connected to the scraper ring 37. The scraper ring 37 surrounds the outer circumference of the cutting tool 4 and can reciprocate along the axial direction of the cutting tool 4 under the drive of the connecting rod 32 to scrape the surface of the cutting tool 4. Specifically, when the chip removal mechanism 3 is working, the transmission shaft 36 eccentrically connected to the turntable 35 drives the end sliding sleeve 34, the sliding sleeve 34 drives the connecting rod 32, the fixing block 331 of the limiting component 33 is fixed to the outer wall of the fixing plate 39 through the pin 332, the connecting rod 32 slides through it, converting the rotational motion into reciprocating linear motion, the limiting block 333 is fixed to the end of the connecting rod 32 to prevent it from falling out, the connecting plate 31 at the end of the connecting rod 32 is connected to the chip scraping ring 37, the chip scraping ring 37 reciprocates around the outer circumference of the cutting tool 4 to scrape the surface.

[0025] Reference Figure 2 and Figure 4 The docking mechanism 2 includes a housing 28 fixed inside the base 1 and a plug 22 for connecting the cutting tool 4. The plug 22 is detachably inserted into the housing 28 to form a coolant delivery channel. To achieve quick locking and releasing between the plug 22 and the housing 28, a radial through hole is provided on the outer wall of the housing 28. The steel ball 26 is housed in the radial through hole. The limiting sleeve 29 and the sliding sleeve 34 are provided on the outer wall of the housing 28. The second spring 27 surrounds the outer wall of the housing 28 and abuts against the limiting sleeve 29. Under the elastic force of the second spring 27, the limiting sleeve 29 can press the steel ball 26 into the slot on the outer wall of the plug 22 to achieve locking. Specifically, the docking mechanism 2 includes a housing 28 fixed inside the base 1 and a plug 22 for connecting the cutting tool 4. The plug 22 is detachably inserted into the housing 28 to form a coolant delivery channel. A steel ball 26 is housed in a radial through hole on the outer wall of the housing 28. A limiting sleeve 29 is provided on the outer wall sliding sleeve 34. A spring 27 surrounds the housing 28 and abuts against the limiting sleeve 29. Its elasticity causes the limiting sleeve 29 to press the steel ball 26 into the slot of the plug 22 to achieve rapid locking and releasing.

[0026] The docking mechanism 2 also includes a piston 24 and a spring 25. Pistons 24 are arranged axially inside the housing 28 and the plug 22. The spring 25 is arranged between two opposing pistons 24. In the un-docked state, the spring 25 pushes the two pistons 24 apart to close the flow channel. After the plug 22 is inserted, the two pistons 24 squeeze each other and compress the spring 25, thereby opening the coolant channel. To prevent impurities from entering the cutting tool 4, the docking mechanism 2 also includes a sieve plate 23. The sieve plate 23 is arranged laterally inside the plug 22 and located in the flow channel behind the piston 24 for filtering coolant. To prevent coolant from leaking from the docking point, the docking mechanism 2 also includes a sealing ring 21. The sealing ring 21 is arranged in the annular groove on the outer wall of the plug 22. After the plug 22 is inserted into the housing 28, the sealing ring 21 is pressed to seal the gap between the outer wall of the plug 22 and the inner wall of the housing 28. Specifically, the docking mechanism 2 also includes a piston 24 and a spring 25. Pistons 24 are provided axially inside the housing 28 and the plug 22. The spring 25 is placed between two opposing pistons 24. When not docked, the spring 25 pushes the pistons 24 to close the flow channel. After the plug 22 is inserted, the pistons 24 squeeze and compress the spring 25 to open the coolant channel. To prevent impurities from entering the cutting tool 4, a sieve plate 23 is also provided laterally in the flow channel behind the pistons 24 inside the plug 22 to filter the coolant. To prevent leakage, a sealing ring 21 is provided in the annular groove on the outer wall of the plug 22. After insertion, the sealing ring 21 is pressed to seal the gap between the plug 22 and the housing 28.

[0027] Reference Figure 3 In the limiting assembly 33, the limiting block 333 is fixedly connected to the end of the connecting rod 32 away from the connecting plate 31. The limiting block 333 is set to prevent the connecting rod 32 from coming off the fixed block 331, thus avoiding the problem of the connecting rod 32 moving axially or coming off during high-speed reciprocating motion. Specifically, in the limiting component 33, the limiting block 333 is firmly fixedly connected to the end of the connecting rod 32 away from the connecting plate 31. Its setting can accurately prevent the connecting rod 32 from coming off the fixing block 331, effectively preventing the connecting rod 32 from axially moving or coming off during high-speed reciprocating motion, and ensuring the motion stability and working reliability of the chip removal mechanism 3. Reference Figure 4A radial through hole is provided on the outer wall of the outer casing 28, allowing the steel ball 26 to move radially within the through hole. A sliding sleeve 34 of the limiting sleeve 29 is located on the outer wall of the outer casing 28. A second spring 27 surrounds the outer wall of the outer casing 28 and abuts against the limiting sleeve 29. The elastic force of the second spring 27 drives the limiting sleeve 29 to axially reset, thereby squeezing the steel ball 26 through the inner wall of the limiting sleeve 29, causing the steel ball 26 to engage in the slot of the plug 22. Pistons 24 are axially arranged inside both the outer casing 28 and the plug 22. A first spring 25 is positioned between two opposing pistons 24, utilizing the elastic force of the first spring 25... The automatic closing and opening of the flow channel is achieved. The structure is simple and reliable. A screen plate 23 is also provided in the docking mechanism 2. The screen plate 23 is horizontally arranged inside the plug 22 and located in the flow channel behind the piston 24. It can effectively filter impurities in the coolant and prevent blockage of the internal channel of the cutting tool 4. A sealing ring 21 is also provided in the docking mechanism 2. The sealing ring 21 is set in the annular groove on the outer wall of the plug 22. When the plug 22 is inserted into the outer shell 28, the sealing ring 21 can be pressed and effectively seal the gap between the outer wall of the plug 22 and the inner wall of the outer shell 28 to prevent high-pressure coolant leakage. Specifically, the outer wall of the outer shell 28 has a radial through hole, through which the steel ball 26 can move radially. The limiting sleeve 29 and the sliding sleeve 34 are located on the outer wall of the outer shell 28. The second spring 27 surrounds the outer shell 28 and abuts against the limiting sleeve 29. Its elastic force drives the limiting sleeve 29 to return to its axial position and squeezes the steel ball 26 through the inner wall so that it is stuck into the slot of the plug 22. Pistons 24 are provided axially inside the outer shell 28 and the plug 22. The first spring 25 is located between two opposing pistons 24. The elastic force realizes the automatic closing and opening of the flow channel. The structure is simple and reliable. In the docking mechanism 2, the sieve plate 23 is arranged laterally in the flow channel behind the piston 24 inside the plug 22. It can effectively filter coolant impurities and prevent blockage of the internal channel of the cutting tool 4. A sealing ring 21 is also provided in the annular groove on the outer wall of the plug 22. After insertion, the sealing ring 21 is pressed tight, effectively sealing the gap between the plug 22 and the outer shell 28 and preventing high-pressure coolant leakage.

[0028] Reference Figure 3 The fixed plate 39 has an internal cavity for the turntable 35 to rotate. The output shaft of the motor 38 passes through the fixed plate 39 and is connected to the turntable 35. This design allows the turntable 35 to be accommodated inside the fixed plate 39, reducing the overall external profile of the mechanism. Specifically, the fixed plate 39 has an internal cavity that is adapted to the turntable 35. This cavity is designed specifically for the rotation of the turntable 35. The output shaft of the motor 38 passes precisely through the fixed plate 39 and is firmly connected to the turntable 35. This embedded design allows the turntable 35 to be completely housed inside the fixed plate 39, which greatly reduces the external outline size of the entire chip removal mechanism 3 and improves space utilization.

[0029] Working principle: During cutting, the motor 38 rotates, driving the turntable 35 to rotate inside the fixed plate 39, which in turn drives the transmission shaft 36 to rotate at the edge of the turntable 35. This squeezes and drives the sliding sleeve 34. Because the sliding sleeve 34 is connected to the connecting rod 32, and the connecting rod 32 can only slide horizontally under the restriction of the limiting component 33, the pin 332 fixes the fixing block 331 to the outer wall of the fixed plate 39, and the limiting block 333 is fixed to the tail of the connecting rod 32 to prevent the connecting rod 32 from sliding out of the hole of the fixing block 331. The sliding in the connecting rod 32 drives the connecting plate 31, and the connecting plate 31 drives the bottom scraper ring 37 on the surface of the tool 4 to scrape away and crush the chips on the surface of the tool 4.

[0030] The machine tool's fluid supply system is connected to the spindle, which is connected to the base 1. Inside the base 1, the tool 4 is connected via a docking mechanism 2. After sliding the limit sleeve 29, the steel ball 26 pops out of the outer hole of the outer shell 28, and the plug 22 is inserted into the inner shell 28. After the plug 22 is inserted, the steel ball 26 slides down to the groove on the outer wall of the plug 22, causing the plug 22 and the piston 24 inside the outer shell 28 to squeeze each other and pass through the middle of the screen plate 23. After docking, the limit sleeve 29 is released and reset under the elastic force of the second spring 27. The compression spring 25 causes the pistons 24 to squeeze each other and create a gap, allowing the coolant to flow through. The coolant flows through the inside of the tool 4 to cool it down. The coolant is then discharged from the outer hole of the tool 4, impacting the chips generated at the cutting point to prevent them from getting entangled in the tool 4, thus affecting the cutting accuracy and the service life of the tool 4. The chip removal mechanism 3 has a sealing ring 21 on the outer wall of the outer shell 28 to prevent the coolant from flowing out of the pipeline.
