Description

Technical Field

[0001] This utility model relates to the field of five-axis machining technology, and in particular to a five-axis machining center for shell machining. Background Technology

[0002] Five-axis machining centers are high-tech, high-precision machining centers specifically designed for machining complex curved surfaces. They have a significant impact on industries such as aviation, aerospace, scientific research, precision instruments, and high-precision medical equipment.

[0003] A search revealed a Chinese patent application with publication number CN220073583U that discloses a five-axis machining center. This center mainly uses the cooperation of a push component and a cleaning component to scrape away liquid from the observation window while the laser head is changing tools.

[0004] Compared with existing technologies in related fields, it can be seen that when a five-axis machining center is machining a workpiece, the coolant nozzles generally spray coolant at a fixed angle at the contact point between the machining head and the workpiece. Some debris will adhere to the dead corner on the other side of the machining head where the coolant is sprayed, making it impossible for the sprayed coolant to effectively clean the debris during machining, which will affect the service life of the machining head and the machining quality of the workpiece. Utility Model Content

[0005] The purpose of this invention is to provide a five-axis machining center for shell machining in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A five-axis machining center for shell processing includes a housing, on which a drive mechanism, a control mechanism, and a coolant outlet valve are provided. Inside the housing, a displacement unit, a machining platform mechanism, a filter screen, and a cleaning unit are provided. The cleaning unit is located between the machining platform mechanism and the filter screen and is slidably connected to the filter screen. A mounting base is installed on the drive mechanism, and a machining head and a coolant spraying unit are installed on the mounting base. A cleaning unit is installed on the displacement unit.

[0008] The coolant spraying unit on the mounting base includes a guide ring, which is mounted on the mounting base. A mounting ring is slidably mounted on the guide ring. Both the guide ring and the mounting ring surround the machining head. A support base is mounted on the mounting ring. A spray valve head is rotatably mounted on the support base at an equal angle. A screw is rotatably connected to the support base. The spray valve head is tilted and communicates with the guide ring. A movable block is threadedly connected to the screw. The movable block is rotatably connected to the upper end of the spray valve head.

[0009] Furthermore, the displacement unit inside the box includes a second motor and a lead screw. There are two second motors and two lead screws. The two second motors are respectively installed on the inside sides of the box, and the two lead screws are rotatably installed inside the box. The two lead screws are threadedly connected to the cleaning unit, and the two lead screws are respectively connected to the output shafts of the two second motors.

[0010] Furthermore, the cleaning unit on the two lead screws includes a mounting frame, with two lead screws threaded to both ends of the mounting frame. A third motor is installed at both ends of the mounting frame. A placement frame is rotatably mounted on the mounting frame. A first arc-shaped plate and a second arc-shaped plate are respectively installed on two corresponding sides of the mounting frame. A water guide pipe is provided on the side of the mounting frame. The output shafts of the two third motors are respectively connected to both ends of the placement frame. Spray heads are rotatably mounted at equal intervals on the placement frame. The spray heads are connected to the water guide pipes. A support rod is movably mounted on the upper end of the spray head. The first arc-shaped plate and the second arc-shaped plate are slidably connected to both ends of the support rod. The arc directions of the first arc-shaped plate and the second arc-shaped plate are opposite.

[0011] Furthermore, the cleaning unit inside the housing includes a first motor and a mounting shaft. The first motor is installed inside the housing, and the mounting shaft is rotatably installed inside the housing. The mounting shaft is connected to the output shaft of the first motor, and a spiral blade is installed on the mounting shaft. The spiral blade is slidably connected to the upper surface of the filter screen.

[0012] Furthermore, there are two liquid outlet valves on the tank.

[0013] Furthermore, two guide plates are inclinedly arranged on both sides of the inside of the box, and the lower ends of the two guide plates are connected to both sides of the filter screen.

[0014] Furthermore, a placement groove is provided on the lower side of the box, and a collection box is slidably installed in the placement groove. The placement groove is connected to the filter screen, and the collection box is located below the spiral blades.

[0015] The advantages compared to existing technologies are as follows:

[0016] 1. The tilted spray valve head automatically rotates when spraying coolant, ensuring uniform circumferential spraying of coolant at the contact point between the machining head and the workpiece. This results in even cooling of the contact area and avoids the impact of continuous coolant spraying on one spot, which could affect the lifespan and machining accuracy of the machining head. Furthermore, the circumferential spraying effectively removes machining debris, preventing debris adhering to corners and affecting the lifespan of the machining head and the quality of the machined workpiece.

[0017] 2. The second motor and lead screw enable the nozzle to clean different areas inside the chamber. The third motor, placement frame, support rod, first arc plate, and second arc plate adjust the tilt position of the nozzle, allowing it to rinse the interior of the chamber at different angles. This ensures effective cleaning of different areas inside the chamber, avoids cleaning dead corners, improves the cleanliness of the chamber after processing, facilitates the next processing and use, eliminates the need for manual cleaning, reduces the workload of workers, and improves work efficiency.

Detailed Implementation

[0032] like Figures 1-11As shown, a five-axis machining center for shell machining includes a housing 1. A drive mechanism 2, a control mechanism 10, and a coolant outlet valve 13 are mounted on the housing 1. Inside the housing 1 are a displacement unit, a machining platform mechanism 9, a filter screen 11, and a cleaning unit. The cleaning unit is located between the machining platform mechanism 9 and the filter screen 11 and is slidably connected to the filter screen 11. A mounting base 7 is mounted on the drive mechanism 2, and a machining head 8 and a coolant spraying unit are mounted on the mounting base 7. The cleaning unit is mounted on the displacement unit. The drive mechanism 2, the machining platform mechanism 9, and the control mechanism 10 are electrically connected. The drive mechanism 2, the control mechanism 10, the machining platform mechanism 9, and the machining head 8 operate using existing technology. The workpiece to be machined is placed on the machining platform mechanism 9, and the drive mechanism 2 drives the machining head 8 via the mounting base 7. The head 8 processes the workpiece, and the multi-axis machining of the workpiece is achieved through the cooperation of the machining platform mechanism 9 and the drive mechanism 2. During machining, the contact position between the machining head 8 and the workpiece is sprayed with coolant by the coolant spraying unit to rinse and clean the debris. The debris and coolant fall onto the filter screen 11, and the debris in the coolant is filtered through the filter screen 11. The filtered coolant is discharged through the outlet valve 13, so that the coolant can be recycled and reused. The cleaning unit cleans the debris filtered on the filter screen 11. After machining is completed, the drive mechanism 2 drives the mounting base 7 and the machining head 8 to reset. The displacement unit drives the cleaning unit to clean the inside of the box 1 to ensure the cleanliness of the box 1 and prevent debris or coolant from adhering and accumulating inside the box 1 for a long time and affecting its use.

[0033] like Figures 5-7As shown, the coolant spraying unit on the mounting base 7 includes a guide ring 301, which is mounted on the mounting base. A mounting ring 302 is slidably mounted on the guide ring 301. Both the guide ring 301 and the mounting ring 302 surround the machining head 8. A support base 303 is mounted on the mounting ring 302. A spray valve head 305 is rotatably mounted on the support base 303 at an equal angle. A screw 304 is rotatably connected to the support base 303. The spray valve head 305 is inclined and communicates with the guide ring 301. The rod 304 is threadedly connected to a movable block, which is rotatably connected to the upper end of the spray valve head 305. The guide ring 301 is connected to an external coolant delivery device. Before machining, according to the size of the machining head 8, the screw 304 is rotated, which drives the movable block to move. The movable block then drives the spray valve head 305 to move, adjusting its orientation so that the coolant sprayed from the spray valve head 305 can be sprayed onto the contact area between the machining head 8 and the workpiece. The machining head 8... During workpiece processing, the external coolant delivery device delivers coolant into the guide ring 301 and diverts it into the spray valve head 305. The coolant is then sprayed out through the spray valve head 305, cooling the contact area between the processing head 8 and the workpiece. This prevents excessively high temperatures at the processing position from affecting the service life of the processing head 8 and the quality of the workpiece. Because the spray valve head 305 is tilted, the coolant sprayed out exerts a reverse force on the spray valve head 305, causing it to rotate. This allows for uniform circumferential spraying of coolant at the contact area between the processing head 8 and the workpiece, ensuring even cooling and preventing the impact of continuous coolant spraying on one spot from affecting the service life and processing accuracy of the processing head 8. Simultaneously, the circumferential spraying at the contact area effectively removes debris during processing, preventing adhering debris from affecting the service life of the processing head 8 and the quality of the processed workpiece.

[0034] like Figure 4 , Figure 6 , Figure 8 , Figure 9 , Figure 11As shown, the displacement unit inside the housing 1 includes a second motor 501 and a lead screw 502. There are two second motors 501 and two lead screws 502. The two second motors 501 are respectively installed on both sides of the inside of the housing 1. The two lead screws 502 are rotatably installed inside the housing 1. The two lead screws 502 are threadedly connected to the cleaning unit. The two lead screws 502 are respectively connected to the output shafts of the two second motors 501. The second motors 501 and the control mechanism 10 are electrically connected. The operation of the second motors 501 adopts existing technology. After processing is completed, the drive mechanism 2 drives the mounting base 7 and the processing head 8 to reset. The second motors 501 drive the lead screws 502 to rotate, and the lead screws 502 drive the cleaning unit to move, adjusting the position of the cleaning unit inside the housing 1 so that the cleaning unit can clean different positions inside the housing 1, ensuring the cleanliness of the inside of the housing 1 after processing.

[0035] like Figure 4 , Figure 6 , Figures 8-11As shown, the cleaning unit on the two lead screws 502 includes a mounting frame 601. The two ends of the mounting frame 601 are threadedly connected to the two lead screws 502 respectively. A third motor 602 is mounted on both ends of the mounting frame 601. A placement frame 603 is rotatably mounted on the mounting frame 601. A first arc-shaped plate 605 and a second arc-shaped plate 608 are respectively mounted on two corresponding sides of the mounting frame 601. A water guide pipe 607 is provided on the side of the mounting frame 601. The two ends of the placement frame 603 are respectively connected to the output shafts of the two third motors 602. Spray heads 606 are rotatably mounted on the placement frame 603 at equal intervals. 606 connects to the water guide pipe 607. A support rod 604 is movably mounted on the upper end of the nozzle 606. The two ends of the support rod 604 are slidably connected to a first arc-shaped plate 605 and a second arc-shaped plate 608, respectively. The arc directions of the first arc-shaped plate 605 and the second arc-shaped plate 608 are opposite. The water guide pipe 607 is connected to an external water supply device. A third motor 602 is electrically connected to the control mechanism 10. The third motor 602 operates using existing technology. After processing, the drive mechanism 2 drives the mounting base 7 and the processing head 8 to reset. The external water supply device delivers clean water into the water guide pipe 607, which then diverts the water into… The water enters the nozzle 606 and is then sprayed out through the nozzle 606 to rinse the inside of the housing 1. Two lead screws 502 drive the mounting bracket 601 to move, allowing rinsing of different locations within the housing 1. A third motor 602 drives the placement bracket 603 to rotate, thereby adjusting the lateral tilt angle of the nozzle 606. Simultaneously, as the placement bracket 603 rotates, it drives the support rod 604 to rotate via the nozzle 606. The two ends of the support rod 604 slide along the first arc-shaped plate 605 and the second arc-shaped plate 608. The arc direction of the arc plate 605 and the second arc plate 608 is opposite. When the support rod 604 moves along the first arc plate 605 and the second arc plate 608, the support rod 604 moves in the longitudinal direction. The support rod 604 drives the nozzle 606 to tilt in the longitudinal direction, so that the nozzle 606 can spray water at different angles in the box 1, ensuring the cleaning effect of different positions in the box 1, avoiding cleaning dead corners, improving the cleanliness of the box 1 after processing, facilitating the next processing and use, eliminating the need for manual cleaning, reducing the workload of workers, and improving work efficiency.

[0036] like Figure 3 , Figure 10As shown, the cleaning unit inside the housing 1 includes a first motor 401 and a mounting shaft 402. The first motor 401 is installed inside the housing 1, and the mounting shaft 402 is rotatably installed inside the housing 1. The mounting shaft 402 is connected to the output shaft of the first motor 401. A spiral blade 403 is mounted on the mounting shaft 402. The spiral blade 403 is slidably connected to the upper surface of the filter screen 11. The first motor 401 and the control mechanism 10 are electrically connected. The first motor 401 and the spiral blade 403 operate using existing technology. After processing, the first motor 401 drives the mounting shaft 402 to rotate, and the mounting shaft 402 drives the spiral blade 403 to rotate. The spiral blade 403 pushes and discharges the filtered debris on the filter screen 11, effectively improving the convenience and efficiency of collecting and processing processing debris.

[0037] like Figure 2 , Figure 10 As shown, there are two liquid outlet valves 13 on the housing 1. One liquid outlet valve 13 is connected to an external wastewater collection device, and the other liquid outlet valve 13 is connected to a coolant collection device. Through the two liquid outlet valves 13, the coolant during processing and the wastewater during cleaning are collected separately to avoid mixing and causing waste, and to facilitate subsequent filtration.

[0038] like Figure 10 As shown, two guide plates 12 are inclinedly arranged on both sides of the inside of the box 1. The lower ends of the two guide plates 12 are connected to the two sides of the filter screen 11 respectively. The guide plates 12 guide the debris during cutting so that the debris enters the filter screen 11, which facilitates the collection and processing of the debris.

[0039] like Figure 1 , Figure 3 As shown, a placement groove 14 is provided on the lower side of the box 1. A collection box 15 is slidably installed in the placement groove 14. The placement groove 14 is connected to the filter screen 11. The collection box 15 is located below the spiral blade 403. When the collection box 15 is installed in the placement groove 14, the spiral blade 403 outputs the debris on the filter screen 11 into the placement groove 14. The debris falls into the collection box 15, which facilitates the processing of the collected debris and improves the convenience and efficiency of debris collection and processing.

[0040] Working principle: such as Figure 1 , Figure 3 , Figure 10 As shown, the workpiece to be processed is placed on the processing platform mechanism 9 and fixed, and the processing head 8 is installed on the mounting base 7, as shown. Figures 5-7 As shown, according to the size of the machining head 8, rotating the screw 304 moves the movable block, which in turn moves the spray valve head 305, adjusting its orientation so that the coolant sprayed from the spray valve head 305 can be sprayed onto the contact area between the machining head 8 and the workpiece; as shown. Figure 1, Figure 3 As shown, the collection box 15 is installed into the placement slot 14;

[0041] like Figure 1 , Figure 3 , Figure 10 As shown, the drive mechanism 2 drives the machining head 8 to process the workpiece via the mounting base 7, and the multi-axis machining of the workpiece is achieved through the cooperation of the machining platform mechanism 9 and the drive mechanism 2; during the machining process, as... Figures 5-7 As shown, the external coolant delivery device delivers coolant into the guide ring 301 and diverts it into the spray valve head 305. The coolant is sprayed out through the spray valve head 305, which can cool the contact area between the machining head 8 and the workpiece. Since the spray valve head 305 is inclined, when the coolant in the spray valve head 305 is sprayed out, it will exert a reverse force on the spray valve head 305, pushing the spray valve head 305 to rotate. This allows the coolant to be sprayed evenly in a circumferential direction at the contact area between the machining head 8 and the workpiece, so that the contact area between the machining head 8 and the workpiece is cooled evenly, and debris around the contact area between the machining head 8 and the workpiece is cleaned up during machining.

[0042] like Figure 10 As shown, cutting debris and coolant fall onto the guide plate 12, which directs the coolant and debris, causing the debris to fall onto the filter screen 11. The filter screen 11 filters the debris from the coolant, and the filtered coolant falls into the lower part of the housing 1. Figure 2 , Figure 10 As shown, the coolant is discharged and collected through the outlet valve 13, and the filtered debris remains on the filter screen 11.

[0043] like Figure 4 , Figure 6 , Figures 8-11 As shown, after processing is completed, the drive mechanism 2 drives the mounting base 7 and the processing head 8 to reset. The external water supply device delivers clean water to the water guide pipe 607, which then diverts the water into the nozzle 606 and sprays it out through the nozzle 606 to rinse the inside of the box 1.

[0044] While rinsing, such as Figure 4 , Figure 6 , Figures 8-11As shown, the third motor 602 drives the placement frame 603 to rotate, thereby adjusting the tilt angle of the nozzle 606 in the lateral direction. When the placement frame 603 rotates, it drives the support rod 604 to rotate through the nozzle 606. The two ends of the support rod 604 slide along the first arc plate 605 and the second arc plate 608. Since the arc directions of the first arc plate 605 and the second arc plate 608 are opposite, when the support rod 604 moves along the first arc plate 605 and the second arc plate 608, the support rod 604 moves in the longitudinal direction. The support rod 604 drives the nozzle 606 to tilt in the longitudinal direction, so that the nozzle 606 can spray water at different angles inside the housing 1.

[0045] At the same time, such as Figure 4 , Figure 6 , Figure 8 , Figure 9 , Figure 11 As shown, the second motor 501 drives the lead screw 502 to rotate, which in turn moves the mounting bracket 601, adjusting the position of the spray nozzle 606 inside the housing 1, enabling a thorough cleaning of the interior of the housing 1. The cleaning wastewater flows through the filter screen 11 into the bottom of the housing 1. Figure 2 , Figure 10 As shown, wastewater is discharged through the discharge valve 13;

[0046] like Figure 3 , Figure 10 As shown, the first motor 401 drives the mounting shaft 402 to rotate, and the mounting shaft 402 drives the spiral blades 403 to rotate. The spiral blades 403 push and discharge the filtered debris on the filter screen 11. When the spiral blades 403 output the debris on the filter screen 11 into the placement groove 14, the debris falls into the collection box 15 and is collected and processed by the collection box 15.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
