Description

Technical Field

It combines CNC technology, milling technology and automatic control technology, and can realize intelligent and high-precision processing of the keyway in the inner hole of the gear. The device usually includes a machine tool body, a clamping part, a milling part, and corresponding control systems and auxiliary equipment;

[0003] During the milling process of the keyway in the gear, in order to reduce the temperature of the tool, reduce tool wear and thermal deformation of the workpiece, cutting fluid is usually sprayed into the processing area. The existing cutting fluid spraying structure is relatively simple. Generally, the spraying flow rate of the cutting fluid is set in advance, and the cutting fluid is sprayed on the tool and the workpiece at a uniform speed, resulting in the cutting fluid spraying speed cannot be adjusted according to the temperature change in the processing area. Not only will too much cutting fluid be sprayed in the initial milling state, resulting in a large amount of cutting fluid waste, increased production costs, and unnecessary pollution to the working environment, but also if the cutting fluid spraying speed is fixed, the temperature of the tool during the milling process will gradually increase, making it impossible for the cutting fluid to promptly and effectively take away the heat generated by milling, resulting in excessive temperatures of the tool and workpiece, thereby affecting the cutting quality and tool life.

[0035] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. 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 creative work are within the scope of protection of the present invention.

[0036] The present embodiment is a gear internal keyway intelligent milling processing device, such as Figure 1 - Figure 8 As shown, it includes a milling table 1, the upper end surface of the milling table 1 is fixedly connected to a support frame 4, the upper end surface of the support frame 4 is fixedly connected to a cylinder 5, the output end of the cylinder 5 is fixedly connected to a piston rod 6, a milling cutter 7 is installed at the end of the piston rod 6 away from the cylinder 5, a milling frame 2 is arranged below the milling cutter 7, the milling frame 2 is fixedly connected to the upper end surface of the milling table 1, a circular hole 3 is opened at the center of the milling frame 2, and a cutting fluid spraying speed adaptive adjustment mechanism is arranged on the support frame 4, and the cutting fluid spraying speed adaptive adjustment mechanism is used to adjust the spraying flow rate of the cutting fluid according to the temperature change around the milling cutter 7.

[0037] In this embodiment, Figure 2 - Figure 4 As shown, the cutting fluid spraying speed adaptive adjustment mechanism includes an infusion tube 801, which is fixedly connected to the support frame 4, one end of the infusion tube 801 is fixedly connected to a nozzle 803, and the end of the infusion tube 801 away from the nozzle 803 is fixedly connected to a liquid storage tank, and a ball valve 802 is installed on the infusion tube 801, and the lower end of the ball valve 802 is rotatably connected to a valve stem 804, and a liquid flow port 810 is opened inside the ball valve 802, and the valve stem 804 is used to control the opening and closing size of the liquid flow port 810, and the liquid flow port 810 is initially in an open state. When the valve stem 804 rotates on the ball valve 802, the opening of the liquid flow port 810 can be increased, so that the cutting fluid inside the infusion tube 801 can flow into the nozzle 803 through the ball valve 802 more quickly for spraying.

[0038] In this embodiment, Figure 3As shown, a spiral groove 808 is provided at the lower end of the outer surface of the valve stem 804, and a ball 809 is slidably connected in the spiral groove 808. A lifting plate 806 is fixedly connected to the ball 809. The lifting plate 806 is sleeved on the outer surface of the valve stem 804. A fixed column 805 is slidably connected to the lifting plate 806 away from the valve stem 804. The fixed column 805 is fixedly connected to the lower end surface of the nozzle 803. When the lifting plate 806 is lifted or lowered on the outer surface of the fixed column 805, the ball 809 will be driven to apply pressure to the spiral groove 808, thereby driving the valve stem 804 to rotate.

[0039] In this embodiment, Figure 4 As shown, a two-way memory alloy wire 807 is fixedly connected to the upper end surface of the lifting plate 806, and one end of the two-way memory alloy wire 807 away from the lifting plate 806 is fixedly connected to the lower end surface of the nozzle 803. The two-way memory alloy wire 807 is sleeved on the outer surface of the fixed column 805. When the temperature near the two-way memory alloy wire 807 changes, the two-way memory alloy wire 807 will be deformed, pushing the lifting plate 806 to rise and fall on the outer surface of the fixed column 805.

[0040] In this embodiment, Figure 8 As shown, a liquid reservoir 13 is provided inside the milling table 1, and a recovery pipe 12 is fixedly connected to the liquid reservoir 13. The recovery pipe 12 passes through and is fixedly connected to the milling table 1. A filter plate 11 is fixedly connected to the upper end surface of the liquid reservoir 13. A collecting tank 10 is symmetrically provided on the upper end surface of the milling table 1. The collecting tanks 10 are respectively located on both sides of the filter plate 11. The cutting fluid will carry the waste together and fall above the filter plate 11, and the cutting fluid will flow into the liquid reservoir 13 through the filter plate 11 and be recycled by the recovery pipe 12.

[0041] In the prior art, during the spraying process of the cutting fluid, the spraying speed cannot be adjusted according to the temperature change of the processing area, which will not only cause excessive cutting fluid to be sprayed in the initial milling state, resulting in a large amount of cutting fluid waste, increased production costs, and unnecessary pollution to the working environment, but also if the spraying speed of the cutting fluid is fixed, the temperature of the tool during the milling process will gradually increase, making it impossible for the cutting fluid to promptly and effectively remove the heat generated by milling, resulting in excessive temperatures of the tool and workpiece, thereby affecting the cutting quality and tool life. Compared with the prior art, the amount of cutting fluid sprayed can be increased or decreased according to the temperature change near the milling cutter 7, which can not only ensure that sufficient cutting fluid is provided when needed to cool the milling cutter 7 and the workpiece, but also reduce spraying when not needed, thereby avoiding unnecessary cutting fluid waste, reducing the amount of cutting fluid used, and reducing production costs, and by controlling the amount of cutting fluid sprayed according to the temperature generated by the milling cutter 7, the milling cutter 7 can be kept running at a suitable working temperature, thereby extending the service life of the milling cutter 7 and reducing the downtime and cost caused by frequent tool replacement.

[0042] In other aspects, this embodiment also provides a cutting impurity collection mechanism for separating the generated cutting waste and cutting fluid, such as Figure 1 , Figure 5 - Figure 7 As shown, the cutting impurity collection mechanism includes a lifting frame 901, which is slidably connected to the side wall of the support frame 4, and the lifting frame 901 is fixedly connected to the piston rod 6. Push rods 902 are rotatably connected to both sides of the lifting frame 901, and the push rods 902 are rotatably connected to the ends of the push rods 902 away from the lifting frame 901. A cleaning plate 903 is fixedly connected between the connecting columns 908, and a sliding column 904 is fixedly connected to the side of the cleaning plate 903 close to the support frame 4, and the sliding column 904 penetrates and is slidably connected to the support frame 4.

[0043] In this embodiment, Figure 5 and Figure 6 As shown, the cutting impurity collection mechanism also includes a symmetrically arranged vertical plate 905, and a slide plate 910 is slidably connected to the side wall of the vertical plate 905. The side of the slide plate 910 away from the vertical plate 905 is rotatably connected to a lifting plate 909, and the lifting plate 909 is rotatably connected to the connecting column 908 at one end away from the slide plate 910. A through groove 911 is opened at the upper end of the slide plate 910. When the connecting column 908 moves back and forth horizontally following the cleaning plate 903, the lifting plate 909 can push the slide plate 910 to synchronously reciprocate and rise and fall on the side wall of the vertical plate 905, thereby changing the height of the through groove 911.

[0044] In this embodiment, Figure 5 and Figure 7 As shown, a rotating shaft 906 is rotatably connected between the two vertical plates 905, and a fan blade 907 is fixedly connected to the outer surface of the rotating shaft 906 close to the milling cutter 7. A paddle 913 is symmetrically fixedly connected to the outer surface of the rotating shaft 906, and a cylinder 912 is fixedly connected to the side of the paddle 913 away from the fan blade 907. The cylinder 912 is slidably connected to the through groove 911. When the cylinder 912 is restricted by the through groove 911 to move up and down, the paddle 913 can paddle the rotating shaft 906 to drive the fan blade 907 to swing up and down synchronously, thereby forming an airflow that blows to the working area of ​​the milling cutter 7.

[0045] Compared with the prior art, the piston rod 6 can reciprocate and extend to drive the milling cutter 7 to cut the workpiece, thereby driving the cleaning plate 903 to reciprocate above the filter plate 11, and pushing the cutting impurities that fall on the upper end surface of the filter plate 11 into the collecting grooves 10 on both sides. This not only avoids the situation in which the cutting fluid is mixed with too many impurities and debris during the recycling process, thereby reducing its cooling, lubrication and cleaning effects, thereby affecting the cutting quality and tool life, but also timely cleaning the impurities on the filter plate 11 can maintain the cleanliness of the cutting fluid and improve its use effect. In addition, the automatic cleaning function can reduce the splashing and accumulation of impurities and debris generated during the cutting process, thereby improving the working environment.

[0046] The working process and principle involved in the overall content of the above embodiment are as follows:

[0047] It should be noted that two-way memory effect alloy is a class of alloy materials with special shape memory effect, which can realize two different shapes at different temperatures. The most common two-way memory effect alloy is nickel titanium alloy (Ni-T i alloy), also known as "Nitinol" alloy or "superelastic alloy", which usually has the following two shapes, high temperature phase and low temperature phase. In the high temperature phase (usually above room temperature), the material is in an elastic shape and can undergo large elastic deformation, while in the low temperature phase (usually below room temperature), the material will return to the preset initial shape. Specifically, the transformation temperature (two-way transformation temperature) of nickel titanium alloy (Ni-Ti alloy) can be adjusted according to the composition and treatment of the alloy. Usually, the high temperature phase transformation temperature ranges from about 40-100°C, and the low temperature phase transformation temperature ranges from about -10 to 30°C. This range can be adjusted according to the needs of specific applications. It should be noted that the shape memory process of the two-way memory effect alloy is reversible, and it can switch between high temperature and low temperature many times and maintain the same memory effect.

[0048] When the staff needs to perform milling processing on the keyway in the gear, first place the gear at the center of the upper end face of the milling frame 2, and align the gear inner groove with the circular hole 3 opened on the milling frame 2, and then fix the gear on the milling frame 2 with the help of the clamping mechanism in the prior art. After the gear is fixed, the staff can open the cylinder 5 to drive the piston rod 6 to extend and retract, so that the milling cutter 7 connected to the piston rod 6 descends into the gear inner groove and performs reciprocating motion to perform milling processing on the gear inner groove. When the cylinder 5 starts to work, the staff can simultaneously allow the cutting fluid to flow into the infusion tube 801. Since the liquid flow port 810 inside the ball valve 802 is initially in an open state, after the cutting fluid enters the infusion tube 801, it can still flow into the nozzle 803 through the ball valve 802, and be sprayed out from the outlet of the nozzle 803, and flow into the milling cutter 7 and the gear inner groove, so as to cool and lubricate the milling cutter 7 and the gear inner groove.

[0049] As the milling cutter 7 continues to process the inner groove of the gear, the temperature of the air near the milling cutter 7 will gradually increase. At this time, the high-temperature air will contact the two-way memory alloy wire 807 connected to the bottom of the nozzle 803, causing the two-way memory alloy wire 807 to deform and extend, pushing the lifting plate 806 to slide downward on the outer surface of the fixed column 805. During the descent of the lifting plate 806, the lifting plate 806 can drive the ball 809 to slide synchronously along the spiral groove 808 opened on the outer surface of the valve stem 804, and the ball 809 will be restricted by the lifting plate 806 and can only slide vertically downward. Therefore, the ball 809 will exert pressure on the spiral groove 808, and the valve stem 804 will be rotated on the ball valve 802 through the spiral groove 808, thereby increasing the liquid flow port 810 inside the ball valve 802, so that the cutting fluid inside the infusion tube 801 can flow into the nozzle 803 more quickly through the ball valve 802, and then the nozzle 803 is opened. The head 803 sprays out, on the contrary, when the air temperature near the two-way memory alloy wire 807 decreases, the two-way memory alloy wire 807 will pull the lifting plate 806 to rise on the outer surface of the fixed column 805, and drive the valve stem 804 to rotate in the opposite direction through the ball 809 and the spiral groove 808, thereby reducing the liquid flow port 810 inside the ball valve 802, so that the amount of cutting fluid sprayed can be increased or reduced according to the temperature change near the milling cutter 7, which can not only ensure that sufficient cutting fluid is provided when needed to cool the milling cutter 7 and the workpiece, but also reduce the spraying when not needed, thereby avoiding unnecessary waste of cutting fluid, reducing the amount of cutting fluid used, and reducing production costs, and by controlling the amount of cutting fluid sprayed according to the temperature generated by the milling cutter 7, the milling cutter 7 can be kept running at a suitable working temperature, thereby extending the service life of the milling cutter 7 and reducing the downtime and cost caused by frequent tool replacement;

[0050] When the piston rod 6 drives the milling cutter 7 to perform reciprocating lifting and lowering, the piston rod 6 can synchronously drive the lifting frame 901 to slide up and down synchronously on the side wall of the support frame 4. At this time, since the push rod 902 is rotatably connected to the side wall of the lifting frame 901, and the initial state of the push rod 902 is an inclined state, when the lifting frame 901 slides up and down reciprocatingly, it can drive the upper end of the push rod 902 to move synchronously, and reciprocate to change the inclination state of the push rod 902. In the process of the push rod 902 state changing, the push rod 902 will push the cleaning plate 903 to move synchronously through the connecting column 908 that is rotatably connected to one end away from the lifting frame 901. Since the side wall of the cleaning plate 903 is connected with a sliding column 904, the sliding column 904 is slidably connected to the support frame 4. Therefore, during the movement of the cleaning plate 903, it will be affected by the sliding column 904 and will perform horizontal linear reciprocating motion, and the milling cutter 7 will perform horizontal linear reciprocating motion on the gear. When the inner groove is processed, milling waste will be generated. These wastes will fall onto the filter plate 11 below through the circular hole 3 along with the cutting fluid. At this time, the cutting fluid will flow into the liquid storage tank 13 opened inside the milling table 1 through the filter plate 11, and will be recycled and reused by the recovery pipe 12 connected to the liquid storage tank 13. The waste falling on the upper end surface of the filter plate 11 will be pushed to the collection tank 10 on both sides of the cleaning plate 903 by the reciprocating motion of the cleaning plate 903, and will be collected in the collection tank 10. This will not only avoid the situation in which the cutting fluid is mixed with too many impurities and debris during the recycling process, thereby reducing its cooling, lubrication and cleaning effects, and thus affecting the cutting quality and tool life, but also timely clean the impurities on the filter plate 11, so as to maintain the cleanliness of the cutting fluid and improve its use effect. In addition, the automatic cleaning function can reduce the splashing and accumulation of impurities and debris generated during the cutting process, and improve the working environment.

[0051] During the reciprocating movement of the cleaning plate 903 to clean the waste, since the outer surface of the connecting column 908 connected to the side wall of the cleaning plate 903 is rotatably connected to the lifting plate 909, and the lifting plate 909 is rotatably connected to the side wall of the slide plate 910 at one end away from the connecting column 908, during the reciprocating movement of the cleaning plate 903, the lifting plate 909 will be pushed by the connecting column 908 to change its own inclination state, driving the slide plate 910 to reciprocate and rise and fall on the side wall of the vertical plate 905. At this time, the slide plate 910 will pass through the through groove 911 opened on the upper end surface to push the cylinder 912 to drive one end of the paddle plate 913 to reciprocate up and down, so that the paddle plate 913 drives the rotating shaft 906 to reciprocate up and down between the two vertical plates 905, driving the fan blades 907 connected to the outer surface of the rotating shaft 906 to swing up and down, forming an airflow, and guiding the high-temperature air generated by the milling cutter 7 during operation to the two-way memory alloy wire 807, which can not only further accelerate the two-way memory alloy wire 807 to sense the high temperature near the milling cutter 7, complete the deformation, and timely adjust the spraying speed of the cutting fluid, but also the formed airflow can be directly blown to the working area of ​​the milling cutter 7, effectively taking away the heat generated during the cutting process, reducing the temperature of the milling cutter 7, and preventing it from being damaged or affecting the cutting accuracy due to overheating.
