Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vertical machining center, and particularly relates to a vertical machining center for machining aircraft parts. BACKGROUND

[0002] With the development of aviation manufacturing technology towards lightweight and high performance, modern aircraft parts widely adopt laminated structures and composite structures composed of various advanced materials. For example, in order to balance the strength and weight reduction requirements, metal materials such as titanium alloy and high-strength aluminum alloy are often laminated and processed with carbon fiber reinforced composite materials (CFRP). In addition, when machining large composite components, large steel or cast iron fixtures are generally used to ensure positioning and clamping accuracy. The diversity of material application directly leads to the diversification and complexity of waste generated in the machining process. In a continuous machining process with one clamping, the spindle tool of the vertical machining center will not only cut the workpiece itself to produce non-ferrous chips such as ductile aluminum chips, high-value titanium alloy chips or light composite material dust, but also may accidentally cut the metal fixture due to the intervention of the machining range or trajectory, resulting in ferrous chips. The waste of various different physical and chemical properties mixed with cooling liquid forms a complex mixture that is difficult to handle directly.

[0003] In the face of such multi-material waste mixture, it is very important to effectively separate it. If the accurate classification and recycling of ferrous and non-ferrous chips (such as non-ferrous metal chips and composite material dust) can be achieved, it will bring significant benefits: on the one hand, it can greatly improve the recovery purity and economic benefits of high-value metal waste (such as titanium alloy and aluminum alloy), avoiding resource waste; on the other hand, it can prevent waste of different properties from contaminating each other, such as preventing light composite material dust from adhering to metal chips, or preventing tough aluminum chips from winding and damaging the processing equipment. Conversely, if various waste is allowed to mix, not only will it cause serious waste of recyclable resources, but it will also cause a series of problems: metal chips may wear out the pump body and block the pipeline; composite material dust may contaminate the cooling liquid, reducing its process performance and shortening its service life; especially, the conductive dust generated by dry machining of composite materials may even pose a certain safety hazard if mixed with metal chips.

Through the characteristics of left-right and up-down movement, the complex machining track is realized by cooperating with other mechanisms. The motor and the threaded rod are arranged in the sliding part 5. The motor drives the threaded rod to rotate as a power source. The rotary motion of the threaded rod is converted into the forward and backward linear motion of the mounting plate 6. This design is combined with the left-right and up-down movement of the machining part 3, and finally realizes the full-range and dead-angle-free machining of the workpiece to be machined, which meets the machining requirements of high precision and complex shape of the aircraft parts.

[0034] One end of the auxiliary rod 9 is fixedly connected with the fixed plate 8, and the other end is fixedly connected with the inner wall of the box body 2, forming a stable support structure. The sliding block 10 is slidably sleeved on the auxiliary rod 9 and is fixedly connected with the bottom of the mounting plate 6. When the mounting plate 6 moves forward and backward under the drive of the sliding part 5, the sliding block 10 will slide synchronously along the auxiliary rod 9. On the one hand, the sliding block 10 provides a guiding action for the mounting plate 6 to ensure the accuracy of the movement track, and on the other hand, the auxiliary rod 9 can share the machining pressure borne by the mounting plate 6, so that the mounting plate 6 is more stable during movement, avoiding deformation or deviation of the mounting plate 6 due to excessive pressure, and ensuring the machining precision.

[0035] The mounting plate 6 is a bearing part of the workpiece to be machined, and the aircraft parts to be machined are directly installed on the mounting plate 6. A groove is formed in the mounting plate 6, which provides an initial discharge channel for the waste and the cooling liquid. At the same time, the flow guide plate 7 on the workbench 4 plays an auxiliary flow guiding role, which can gather the waste and the cooling liquid scattered around the mounting plate 6 to the slot of the mounting plate 6, so that the waste and the cooling liquid can flow out smoothly through the slot. After being guided by the flow guide plate 7, the waste and the cooling liquid directly flow into the collection groove 11 arranged around the workbench 4. The collection groove 11 serves as a primary collection structure and can temporarily store the waste and the cooling liquid to avoid pollution of the machining environment.

[0042] The rotating directions of the inner rotating drum 22 and the outer rotating drum 13 are opposite, the reverse rotating design can make the waste scraps inside the inner rotating drum 22 produce more violent stirring, make the waste scraps fully contact with the eye of the inner rotating drum 22, improve the screening efficiency, and also can make the waste scraps falling into the outer rotating drum 13 more fully contact with the magnetic assembly 31, improve the iron scrap adsorption effect.

[0046] When the scraper 29 moves outward under the driving of the fixed rod 26, the inserting rod 27 gradually approaches the piston block one 38 and finally abuts against the piston block one 38; with the continuous movement of the scraper 29, the inserting rod 27 pushes the piston block one 38 to move to the inside of the air groove 37, the spring one 39 is compressed, the gas in the air groove 37 is compressed due to the space reduction, the high-pressure gas pushes the piston block two 40 to move away from the piston block one 38, the piston block two 40 drives the push plate 30 to slide along the scraper 29, and the iron filings on the scraper 29 are swept to the unloading guide plate 23, so that the complete unloading of the iron filings is realized.

[0048] Referring to Figures 1-9 The working principle of the present application is as follows: the aircraft parts to be processed are installed on the mounting plate 6, and the clamping and fixing of the workpiece are completed; the equipment is started, the driving part 16 starts to work, the driving part 16 drives the driving gear 17 to rotate, the driving gear 17 drives the driven gear 25 to rotate through the meshing connection on one hand, and drives the belt pulley one 19 to rotate through the transmission rod 18 on the other hand, the belt pulley one 19 drives the belt pulley two 21 to rotate through the transmission belt 20, and the belt pulley two 21 drives the inner rotating cylinder 22 to rotate (the inner rotating cylinder 22 rotates in the opposite direction of the outer rotating cylinder 13).

[0049] The processing part 3 (integrating the tool changing mechanism, the moving mechanism and the processing part) can realize left and right and up and down movement. The motor drives the screw rod in the sliding part 5 to rotate, and drives the mounting plate 6 to move forward and backward. Under the cooperation of the processing part 3 and the sliding part 5, the processing part 3 can realize all-directional processing of the workpiece to be processed. At the same time, the auxiliary rod 9 and the sliding block 10 ensure that the mounting plate 6 is stable during movement and can bear a large processing pressure, thereby ensuring the processing precision.

[0050] The waste and the cooling liquid are collected and guided. The waste and the cooling liquid generated during processing are discharged through the groove on the mounting plate 6, guided by the guide plate 7 and then flow into the collecting groove 11. The waste and the cooling liquid entering the collecting groove 11 are collected through the inner flow groove 12 and then directly sprayed into the inner rotating cylinder 22 through the spray pipe 42.

[0051] The waste is graded, screened and separated. The inner rotating cylinder 22 is inclined and rotates, and the holes on the surface of the inner rotating cylinder 22 screen the waste. The larger waste (such as long aluminum scraps) is intercepted on the inner rotating cylinder 22 and slides to the collecting port one 34 for collection with the rotation of the inner rotating cylinder 22. The smaller waste and the cooling liquid fall onto the outer rotating cylinder 13 through the holes of the inner rotating cylinder 22, and most of the cooling liquid directly falls at the spiral conveying blade 32 at the end of the outer rotating cylinder 13. The outer rotating cylinder 13 rotates to drive the spiral conveying blade 32 to rotate, and pushes the cooling liquid and part of the waste to the other end of the outer rotating cylinder 13. In the process, the magnetic assembly 31 adsorbs the iron scraps in the mixed waste, and the non-iron small waste and the cooling liquid enter the collecting port two 35 with the rotation of the outer rotating cylinder 13, and then are further separated by the vortex separator connected to the collecting port two 35.

[0052] The iron scraps are unloaded and collected. After a certain amount of cooling liquid and waste is processed, the outer rotating cylinder 13 is temporarily stopped. The fixed rod 26 (controlled by a gas cylinder or an electric push rod) drives the scraper 29 to move towards the port of the outer rotating cylinder 13, and the scraper 29 scrapes the iron scraps on the magnetic assembly 31 (a small part of the iron scraps directly falls on the unloading guide plate 23 through the scraper 29). When the scraper 29 continues to move outward, the plug rod 27 on the baffle 24 abuts against the piston block one 38 and is inserted into the air groove 37. The piston block one 38 moves towards the air groove 37 to compress the spring one 39. The gas in the air groove 37 pushes the piston block two 40 to drive the push plate 30 to move (the spring two 41 is stretched), and the push plate 30 sweeps the iron scraps on the scraper 29 to the unloading guide plate 23, and finally the iron scraps fall into the collecting port three 36 for collection through the unloading guide plate 23.

[0053] In the application, the vertical machining center realizes accurate classification of machining waste of aircraft parts through three-stage separation; coarse separation is completed by the inner rotating cylinder 22, which is inclined and reversely rotates, and the surface holes intercept large pieces of aluminum chips and other large pieces of chips, and the chips fall into the collecting port one 34 along the inner rotating cylinder 22; the second-stage separation relies on the magnetic attraction assembly 31 on the inner wall of the outer rotating cylinder 13, when the outer rotating cylinder 13 rotates, the spiral conveying blade 32 pushes small waste and cooling liquid, the iron chips are adsorbed by the magnetic attraction assembly 31, and then are cleaned to the collecting port three 36 through the scraper 29 and the push plate 30, and the non-iron waste enters the collecting port two 35; the third-stage separation relies on the vortex separator connected with the collecting port two 35, and utilizes the density difference to separate the titanium chips, the relatively heavy aluminum chips and aluminum powder, and dust, so as to realize efficient separation of multiple types of waste.

[0054] The above is only the preferred specific implementation of the application, but the protection scope of the application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the application within the technical range disclosed by the application, which should be covered in the protection scope of the application.
