Description

Technical Field

[0001] The utility model relates to the technical field of five-axis machining of titanium alloy casings, in particular to a fixed-column double-support horizontal five-axis machining center. Background Art

[0002] The aircraft engine is the core component of the aircraft, and the casing is one of the key components of the aircraft engine. Its structure is extremely complex and difficult to manufacture. The main material of the casing is titanium alloy, which is a difficult-to-process material with a relative machinability of 0.15-0.25 and a processing efficiency of only 10% of that of aluminum alloy. The low processing efficiency seriously restricts the mass production of modern aircraft. In the processing process from rough to finished product of the casing, about 70% of the material is removed, most of which is completed in the rough processing stage of the casing. According to experience, the rated torque of the CNC machine tool spindle used for rough processing of titanium alloys should not be less than 1000Nm. Therefore, the development of a high-torque pentahedron processing equipment is the key to achieving efficient processing of the casing and shortening the manufacturing cycle. To process a 1m-level casing, the spindle needs to have high torque and rigidity.

[0003] However, the columns of traditional T-bed processing equipment have poor ability to resist cutting forces and are prone to deformation, affecting processing accuracy. Utility Model Content

[0004] In order to solve the problem that the columns of traditional T-type bed processing equipment have poor ability to resist cutting force and are prone to deformation, which affects the processing accuracy, the utility model provides a fixed column double-support horizontal five-axis machining center.

It should be noted that the maximum deformation point of the simply supported beam structure is in the middle. Under the same conditions, the maximum deformation of the simply supported beam structure is only one sixteenth of that of the cantilever beam structure. In addition, compared with the processing equipment with a T-bed stepped guide rail arrangement, it can reduce the mass of moving parts and have better dynamic performance.

[0037] See also Figure 1 , which is a structural schematic diagram of a fixed column double support horizontal five-axis machining center 100 provided by the utility model. Figures 1 to 6 The fixed-column double-support horizontal five-axis machining center 100 includes: a base 10; a column 20, which is arranged on one side of the base 10; a saddle 30, which is slidably arranged on the column 20; and a spindle part 40, which is slidably arranged on the saddle 30; wherein the column 20 is a simply supported beam structure.

[0038] It is understandable that by setting the column 20 of the fixed column double-support horizontal five-axis machining center 100 to a simply supported beam structure, the ability of the column 20 to resist cutting force can be improved, and the force is more stable compared to the column of the cantilever beam structure used in the traditional T-bed processing equipment. It should be noted that the maximum deformation point of the simply supported beam structure is in the middle. Under the same conditions, the maximum deformation of the simply supported beam structure is only one sixteenth of that of the cantilever beam structure. In addition, compared with the processing equipment with a T-bed stepped guide rail arrangement, it can reduce the mass of moving parts and have better dynamic performance.

[0039] Furthermore, the column 20 includes: a column upper cross beam 21; and two side supports 23, which are respectively connected to both sides of the column upper cross beam 21 and are used to support the column upper cross beam 21. The column upper cross beam 21 and the two side supports 23 are an integrally formed structure. For example, the column 20 is a door frame column.

[0040] It can be understood that by configuring the column 20 in the form of a column upper beam 21 and two side supports 23, the two ends of the column upper beam 21 can be supported by the two side supports 23 connected to the two sides of the column upper beam 21, thereby forming a column 20 with a simply supported beam structure.

[0041] Furthermore, the fixed-column double-support horizontal five-axis machining center 100 also includes: a lower crossbeam 22 of the column, connected to the side support member 23; a first screw assembly 51, arranged on the upper crossbeam 21 of the column, drivingly connected to the saddle 30; a second screw assembly 52, arranged on the lower crossbeam 22 of the column, drivingly connected to the saddle 30.

[0042] It is understandable that by providing a lower cross beam 22 of the column connected to the side support member 23, a box-type structure of the column 20 can be formed, further improving the anti-cutting ability and support stability of the column 20. By providing a first screw assembly 51 for driving and connecting the saddle 30 on the upper cross beam 21 of the column, and providing a second screw assembly 52 for driving and connecting the saddle 30 on the lower cross beam 22 of the column, the saddle 30 can be driven to slide on the column 20 by the first screw assembly 51 and the second screw assembly 52. ​​Compared with the single-screw drive of traditional processing equipment, the use of a double-screw drive method can make the driving force of the first screw assembly 51 and the second screw assembly 52 pass through the center of gravity of the saddle 30, effectively reducing the vibration caused by the processing equipment during acceleration and deceleration, avoiding the problem of overturning caused by unbalanced load, and thus improving the movement accuracy of the saddle 30.

[0043] Furthermore, the fixed-column double-support horizontal five-axis machining center 100 also includes: a first sliding assembly 60, arranged between the upper crossbeam 21 of the column and the saddle 30; a second sliding assembly 70, arranged between the lower crossbeam 22 of the column and the saddle 30; wherein the saddle 30 is slidably arranged on the column 20 through the first sliding assembly 60 and the second sliding assembly 70.

[0045] Furthermore, the first sliding assembly 60 includes a first sliding rail 61 arranged on the upper cross beam 21 of the column and a first sliding member 62 arranged on the saddle 30; the second sliding assembly 70 includes a second sliding rail 71 arranged on the lower cross beam 22 of the column and a second sliding member 72 arranged on the saddle 30; wherein, the first sliding member 62 is slidably connected to the first sliding rail 61, and the second sliding member 72 is slidably connected to the second sliding rail 71.

[0046] It can be understood that by providing a first slide rail 61 on the upper cross beam 21 of the column, providing a second slide rail 71 on the lower cross beam 22 of the column, providing a first sliding member 62 on the saddle 30 that is slidably connected to the first slide rail 61, and providing a second sliding member 72 on the saddle 30 that is slidably connected to the second slide rail 71, the saddle 30 can be driven to slide on the upper cross beam 21 of the column and the lower cross beam 22 of the column through the first sliding member 62 and the second sliding member 72.

[0047] Furthermore, the saddle 30 includes: a main body 31; a first screw connecting part 32 connected to the first screw assembly 51; and a second screw connecting part 33 connected to the second screw assembly 52; wherein the main body 31 is a box-type structure.

[0048] It can be understood that by configuring the saddle 30 to be in the form of a main body 31, a first screw connecting part 32 and a second screw connecting part 33, the driving force of the first screw assembly 51 can be transmitted to the saddle 30 through the first screw connecting part 32, and the driving force generated by the second screw can be transmitted to the saddle 30 through the second screw connecting part 33, thereby driving the saddle 30 to slide on the column 20; by configuring the main body 31 to be a box-type structure, the force stability of the main body 31 can be improved, thereby improving the force stability of the saddle 30.

[0049] Furthermore, the fixed-column double-support horizontal five-axis machining center 100 also includes: a slide 80, which is arranged between the saddle 30 and the main shaft part 40, connecting the saddle 30 and the main shaft part 40; wherein the main shaft part 40 is slidably arranged on the saddle 30 through the slide 80.

[0050] It can be understood that by disposing the ram 80 between the saddle 30 and the main shaft, the main shaft portion 40 can be slidably disposed on the saddle 30 through the ram 80 .

[0051] Furthermore, the fixed-column double-support horizontal five-axis machining center 100 also includes: a third screw assembly 53, which is arranged between the main body 31 and the slide 80, and drives the slide 80; a fourth screw assembly 54, which is arranged between the main body 31 and the slide 80, and drives the slide 80.

[0052] It can be understood that by arranging the third screw assembly 53 and the fourth screw assembly 54 between the main body 31 and the ram 80, and arranging the third screw assembly 53 to drive the ram 80, and arranging the fourth screw assembly 54 to drive the ram 80, the ram 80 can be driven to slide on the saddle 30 by the third screw assembly 53 and the fourth screw assembly 54. Compared with the single screw drive of the traditional processing equipment, the double screw drive mode can make the driving force of the third screw assembly 53 and the fourth screw assembly 54 pass through the center of gravity of the ram 80, effectively reducing the vibration caused by the processing equipment during acceleration and deceleration, avoiding the problem of rollover caused by eccentric load, and thus improving the motion accuracy of the ram 80.

[0053] Furthermore, the fixed column double support horizontal five-axis machining center 100 further includes: a third sliding assembly 91, which is arranged between the main body 31 and the ram 80; a fourth sliding assembly 92, which is arranged between the main body 31 and the ram 80; wherein the ram 80 is slidably arranged on the saddle 30 through the third sliding assembly 91 and the fourth sliding assembly 92. For example, the third sliding assembly 91 includes a third slide rail 911 arranged on the main body 31 and a plurality of third sliders 912 slidably arranged on the third slide rail 911; the fourth sliding assembly 92 includes a fourth slide rail 921 arranged on the main body 31 and a plurality of fourth sliders 922 slidably arranged on the fourth slide rail 921; and the ram 80 is fixedly connected to the plurality of third sliders 912 and the plurality of fourth sliders 922.

[0054] It is understandable that by disposing the third sliding assembly 91 and the fourth sliding assembly 92 between the main body 31 and the ram 80 , the sliding of the ram 80 on the saddle 30 can be achieved through the third sliding assembly 91 and the fourth sliding assembly 92 .

[0055] Furthermore, the spindle portion 40 includes: a spindle body 41 ; a swing assembly 42 swingably disposed on the spindle body 41 ; and a spindle head 43 rotatably disposed on the swing assembly 42 .

[0057] In a specific embodiment, in combination Figures 2 to 4, the main shaft 40 is slidably arranged on the saddle 30 through the ram 80. The driving force of the third screw assembly 53 and the fourth screw assembly 54 passes through the center of gravity of the ram 80, driving the ram 80 to slide along the Y axis on the saddle 30. The first screw assembly 51 and the second screw assembly 52 drive the saddle 30 to slide along the Z axis on the column 20, and the driving force of the first screw assembly 51 and the second screw assembly 52 passes through the center of gravity of the saddle 30.
