Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of inverted milling and turning composite machining, in particular to a five-axis numerical control machine tool inverted turning and milling composite machining device. BACKGROUND

[0002] The inverted milling and turning composite machining device of the five-axis numerical control machine tool is a highly integrated advanced intelligent manufacturing equipment, which combines five-axis linkage machining, inverted structure design and turning and milling composite process, can realize high-precision and high-efficiency machining of complex parts, and the inverted setting can be more convenient for chip falling, prevent chip retention on the workpiece, and help to improve the machining precision of the workpiece.

[0003] The existing chip removal mechanism in the five-axis inverted turning and milling composite machining machine tool often adopts the form of spiral chip removal for chip removal operation in order to improve the chip removal effect and reduce the cost. The spiral chip removal mechanism generates a spiral pushing effect in the chip removal process through the rotation of the screw rod and the chip removal channel to discharge the chips in the chip removal channel. The screw rod of the spiral chip removal mechanism is in the form of a spiral spring, and in order to achieve better chip removal effect and prevent the chip removal path of the screw rod from being blocked, generally only one end of the screw rod is connected with the motor output shaft and the other end is limited in the chip removal channel by a baffle. In order to prevent wear between the screw rod and the side wall of the chip removal channel, and to reduce the chip removal resistance, the screw rod and the side wall of the chip removal channel often have a certain gap. However, when machining large workpieces for dry turning and milling chip operation, chips will accumulate in the chip removal channel. When the chip removal capacity of the screw rod is exceeded, the axial thrust and radial torque generated when the screw rod pushes the chips will increase sharply, thus causing deformation of the screw rod, and even causing the screw rod to bend and be scrapped. In the process of turning and milling the workpiece that needs to be processed with cutting fluid, the chips mixed with the cutting fluid are easily attached to the side wall of the chip removal channel. After a period of time when the cutting fluid stops being sprayed, the chips mixed with the cutting fluid on the side wall of the chip removal channel will dry and form clumps, causing the chip removal channel to be blocked.

[0004] In order to solve the above problems, the existing technology often adds a baffle to the spiral channel to prevent the screw rod from being twisted and deformed, and performs a large-area flushing of the base part after machining to prevent the chip removal channel from being blocked. However, the addition of the baffle increases the resistance during chip removal, causing the chip removal process to be not smooth, and the flushing method after machining cannot avoid the mixed liquid chips adhering to the side wall of the chip removal channel during the machining process. Moreover, the water flow will be difficult to flush away after the mixed liquid chips dry and form clumps during the machining process.

[0005] Therefore, a five-axis numerical control machine tool inverted turning and milling composite machining device is proposed. SUMMARY

[0006] The purpose of the present application is to provide a five-axis numerical control machine tool inverted turning and milling combined machining device, which solves the problems that the screw rod is easy to deform during the process of discharging a large amount of chips, and the chips mixed with cutting fluid are easy to adhere to the side wall of the chip discharge channel.

[0036] As an embodiment of the present application, referring to Figure 2 and Figure 4 The matching part 83 comprises an extension plate 831 fixedly connected to the outside of the base 1, a rotating shaft 832 rotatably connected to the extension plate 831, an automatic winding disc 833 fixedly connected to the rotating shaft 832, a water pipe 834 arranged on the automatic winding disc 833, and a water pump 835 arranged outside the base 1; one end of the water pipe 834 is connected to the collecting box 81 and the other end is connected to the water pump 835; the automatic winding disc 833 can tighten the collecting box 81 connected thereto to be straight, preventing the collecting box 81 from being bent during the movement of the moving seat 5 and affecting the turning-milling operation, and the automatic winding disc 833 can move with the collecting box 81 to swing freely on the extension plate 831 through the rotating shaft 832, and the water pump 835 can continuously extract the cutting fluid in the collecting box 81 through the water pipe 834.

[0037] As an embodiment of the present application, refer to Figure 3 and Figure 4 , a plurality of said metal pipes 71 are communicated through connecting pipes 711, and said connecting pipes 711 are connected with the output end of the water pump 835; when the water pump 835 works, the cutting fluid in the collecting box 81 can be pumped into the connecting pipes 711, and then into each metal pipe 71 along the connecting pipes 711.

[0038] As an embodiment of the present application, refer to Figure 5 and Figure 6 , said cleaning assembly 9 comprises an annular groove 91 opened in the middle of the rotating disc 72, a water flow channel 92 opened in the push rod 73, a discharge port 93 arranged on the metal pipe 71, an abutting strip 94 arranged on the discharge port 93, and a switching piece 95 arranged in the water flow channel 92; said water flow channel 92 is communicated with the annular groove 91; said discharge port 93 is located in the annular groove 91 and fits with the annular groove 91; when the cutting fluid is pumped into each metal pipe 71 through the water pump 835, it will be discharged from the discharge port 93 on the metal pipe 71, and finally discharged along the water flow channel 92 on the push rod 73.

[0039] As an embodiment of the present application, refer to Figure 2 and Figures 5 to 9The switching piece 95 includes a fixed disc 951 fixedly connected in the water flow channel 92, a connecting rod 952 slidably connected on the fixed disc 951, a ball 953 fixedly connected on the connecting rod 952, a spring 954 arranged between the ball 953 and the fixed disc 951, a water outlet hole 955 opened at the end of the connecting rod 952, and a water inlet hole 956 opened on the ball 953; the connecting rod 952 and the ball 953 are hollow inside; the end of the water flow channel 92 is further fixedly connected with a partition block 96; the partition block 96 divides the end of the water flow channel 92 into two equal channels; in the turning and milling process of the workpiece needing to be sprayed with cutting fluid, the water pump 835 will pump the turning fluid in the collecting box 81 to each discharge port 93; in the process of the screw rod 3 rotating and driving the rotating disc 72 to rotate, when the ball 953 passes through the discharge port 93, the ball 953 will be abutted by the abutment strip 94 on the discharge port 93, and will be received in the water flow channel 92 against the force of the spring 954; at this time, the water outlet hole 955 on the connecting rod 952 will also be exposed from the fixed disc 951, the cutting fluid will flow from the water inlet to the ball 953 and the connecting rod 952 and then to the water flow channel 92 from the water outlet, so that the cutting fluid can only be discharged from the water flow channel 92 within the range of the discharge port 93, and under the action of the partition block 96, the water flow at the end of the water flow channel 92 will become two flows and will be respectively sprayed to the side walls of the chip removal channel 2; the ball 953 not passing through the discharge port 93 will be abutted by the spring 954 and the metal pipe 71, and the water outlet will be in the fixed disc 951, so that the water flow channel 92 where the ball 953 not passing through the discharge port 93 cannot discharge liquid; when the ball 953 passes through the discharge port 93, the ball 953 will be pushed out to abut against the metal pipe 71, and the water outlet will be received in the fixed disc 951, so that the liquid cannot be discharged at this time; therefore, when the pushing rod 73 on the rotating disc 72 rotates and passes through the discharge port 93, the water flow will be automatically closed. Since the maximum height of the liquid that can be sprayed is only the highest height of the side wall of the chip removal channel 2 due to the cooperation of the angle range of the discharge port 93 and the water flow channel 92 in the pushing rod 73, the upward spraying of the water flow out of the chip removal channel 2 can be prevented during the spraying process of the side wall of the chip removal channel 2.

[0040] Working principle: refer to Figure 1 and Figure 2 In the working process, the clamping seat 4 can move up and down and rotate by 360 degrees, the moving seat 5 can move forward, backward, left and right on the base 1, and the turning and milling work of the workpiece can be completed by the position movement of the moving seat 5 and the clamping seat 4 in cooperation with the cutting tool, and the turning and milling chips can be discharged through the screw rod 3 in the chip removal channel 2.

[0041] Refer to Figures 1 to 3In the turning and milling operation of large workpieces, the motor drives the screw rod 3 to rotate to realize the chip removal operation. The screw rod 3, the rotating disc 72 and the push rod 73 on the rotating disc 72 form a worm gear mechanism. The rotating screw rod 3 pushes the rotating disc 72 to rotate continuously through the push rod 73. The rotating disc 72 limits the screw rod 3 in the chip removal channel 2, preventing the screw rod 3 from being twisted during the process of pushing a large amount of chips. At the same time, the rotating disc 72 in the rotating process can continuously compact the chips in the middle of the screw rod 3 through the push rod 73, reducing the occupied space of the chips, thereby improving the chip removal efficiency under the condition of the same rotating speed of the screw rod 3. The conical shape of the push rod 73 can prevent the strip-shaped chips from winding around the push rod 73. When the strip-shaped chips wind around the push rod 73, the push rod 73 is stripped from the push rod 73 by the rotation of the rotating disc 72 and the friction between the push rod 73 and the screw rod 3.

[0042] Referring to Figures 1 to 9 When the workpiece needs to be sprayed with cutting fluid during cutting, the cutting fluid is sprayed upward from the nozzle around the main shaft 6, and finally the cutting fluid falls near the main shaft 6 and is collected by the collection box 81. The chips carried by the cutting fluid are filtered by the filter screen 82. At the same time, the water pump 835 draws the turning fluid in the collection box 81 through the water pipe 834, and pumps the cutting fluid into each discharge port 93 along the connecting pipe 711 and the metal pipe 71. During the rotation of the screw rod 3 and the rotating disc 72, when the ball 953 passes through the discharge port 93, the ball 953 is abutted by the abutment strip 94 on the discharge port 93, and is pushed into the water flow channel 92 against the force of the spring 954. At this time, the water outlet hole 955 on the connecting rod 952 is also exposed to the fixed disc 951 and is below the fixed disc 951. The cutting fluid flows from the water inlet to the ball 953 and the connecting rod 952 and from the water outlet to the water flow channel 92. Therefore, it is realized that the cutting fluid can only be discharged from the water flow channel 92 within the range of the discharge port 93, and under the action of the partition block 96, the water flow at the end of the water flow channel 92 is changed into two streams and is respectively rushed to the side walls on both sides of the chip removal channel 2. The ball 953 not passing through the discharge port 93 is abutted by the metal pipe 71 under the action of the pushing force of the spring 954, and the water outlet is in the fixed disc 951. Therefore, the water flow channel 92 where the ball 953 not passing through the discharge port 93 cannot discharge liquid. Moreover, when the ball 953 passes through the discharge port 93, it is pushed out and abutted by the metal pipe 71, and the water outlet is also collected into the fixed disc 951. At this time, the liquid cannot be discharged. Therefore, when the push rod 73 on the rotating disc 72 rotates and passes through the discharge port 93, the water flow is automatically closed. Because the angle range of the discharge port 93 cooperates with the water flow channel 92 in the push rod 73, the maximum height of the liquid spray is only the highest height of the side wall of the chip removal channel 2, preventing the water flow from being sprayed upward out of the chip removal channel 2.

[0043] Even though we have provided specific embodiments of the present application, it should be clear to those skilled in this art that many changes, modifications, substitutions and alterations to these embodiments can be made without departing from the spirit and scope of the present application.
