Description

Technical Field

[0001] The invention relates to the technical field of manned aircraft manufacturing, and in particular to a rapid cutting device suitable for manned aircraft. Background Art

[0002] At present, automated mechanical cutting equipment is widely used in the manned aircraft manufacturing field, and its core processes include loading, positioning, cutting and unloading.

[0003] The existing technology is mainly implemented through the following solutions; dual-manipulator collaborative system: material transfer is completed through independent loading and unloading manipulators. Although this solution improves the level of automation, it requires the configuration of two sets of manipulators and supporting control systems, resulting in high equipment costs (the cost of a single manipulator is usually more than one million yuan) and increased floor space. Although the dual-manipulator system is more efficient, the equipment investment cost increases by 60%-80%, and two sets of servo drive systems and visual positioning modules are required, which increases maintenance costs (the average annual maintenance cost is 15% of the equipment cost). The dual-manipulator system consumes up to 25kW / h, while the main cutting equipment consumes only 8-10kW / h, and the energy structure is unreasonable.

[0004] Composite cutting platform: Material flow is achieved through the combination of conveyor belt and robot. However, the conveyor belt is not accurate enough and requires additional deviation correction devices. In addition, the robot needs to frequently switch the loading and unloading paths during the cutting process, which limits efficiency.

[0005] Single-manipulator multi-task system: Some equipment attempts to achieve loading and unloading functions by using a single manipulator equipped with multiple fixtures, but the manipulator needs to be reset frequently, and the cutting cycle is extended by about 30%, which is difficult to meet the high-frequency cutting requirements of 5 to 8 times per hour for aircraft parts. The single-manipulator multi-task system requires double the operating space, resulting in a bloated equipment layout, which conflicts with the high-density production line requirements of the aircraft assembly workshop.

[0006] To this end, the existing cutting equipment needs to be upgraded. Summary of the invention

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] like Figure 1-Figure 11 As shown, a rapid cutting device suitable for a manned aircraft comprises a base plate 1 on which a fixing frame 4 is fixed.

[0033] A cutting platform 36 is fixed above the bottom plate 1 , and the cutting platform 36 is located in the fixing frame 4 .

[0034] A cutting unit is disposed in the fixed frame 4 above the cutting table 36 .

[0037] A second conveyor belt 29 is installed above the bottom plate 1 on one side of the cutting table 36 , and first conveyor belts 3 are arranged on both sides of the bottom plate 1 below the second conveyor belt 29 .

[0038] A plurality of support assemblies are stacked on the upper end of the bottom plate 1 on the other side of the cutting table 36, and a plate 31 is placed in the support assembly. Specifically, a step is processed in the support seat 32, and the plate 31 is supported by the step in the support seat 32. The width of the second conveyor belt 29 is smaller than the width of the plate 31.

[0039] The support assembly includes two symmetrically arranged support seats 32 . The two support seats 32 have wedge grooves 34 formed on their opposite ends. The lower groove wall of the wedge groove 34 is inclined downward at one end away from the plate 31 .

[0040] A plurality of limiting grooves 33 are formed at the lower end of the support seat 32 , and a second limiting pin 35 corresponding to the limiting groove 33 is fixed at the upper end of the support seat 32 . The second limiting pin 35 is inserted into the limiting groove 33 of the adjacent upper support seat 32 .

[0041] A first limiting pin 2 corresponding to the limiting groove 33 is fixed on the bottom plate 1 , and the first limiting pin 2 is inserted into the limiting groove 33 of the adjacent upper support seat 32 .

[0042] By means of the plug-in fit between the first limiting pin 2 and the limiting groove 33 , and the plug-in fit between the second limiting pin 35 and the limiting groove 33 , the stability of the multiple stacked supporting components can be improved.

[0043] Two symmetrical rotating units are arranged in the fixed frame 4, and the cutting table 36 is located between the two rotating units. The two rotating units correspond to the two supporting seats 32 of the supporting assembly one by one, and the sliding plate 20 is rotatably connected to the rotating unit.

[0044] Specifically, the rotating unit includes a fixed plate 14 fixed in the fixed frame 4, a motor 15 is fixed on the fixed plate 14, a fixed block 16 is fixed on the output shaft of the motor 15, a sliding rod 17 is slidably arranged on the fixed block 16, a connecting seat 18 is fixed at one end of the sliding rod 17, the connecting seat 18 is connected to the fixed block 16 through a first spring 19, and the connecting seat 18 is rotatably connected to the sliding plate 20.

[0045] The sliding plate 20 is located outside the bottom plate 1 . A vertical rod 13 is slidably provided on the sliding plate 20 . The vertical rod 13 is slidably connected to the cross rod 10 . The cross rod 10 is fixed in the fixing frame 4 .

[0046] A connecting rod 9 is fixed in the fixed frame 4, and there are two connecting rods 9. A cross bar 10 is arranged on the upper and lower sides of the vertical rod 13, and the upper cross bar 10 is fixed between the two connecting rods 9. A clearance groove 11 is opened at the lower end of the fixed frame 4, and the lower cross bar 10 is fixed in the clearance groove 11. Slide blocks 12 are slidably arranged on the cross bar 10, and the upper and lower ends of the vertical rod 13 are fixedly connected to the upper and lower slide blocks 12 respectively.

[0047] The opposite ends of the two sliding plates 20 are both provided with clamping components.

[0048] The clamping assembly includes a clamping unit and a supporting unit. The clamping unit corresponds to the wedge groove 34, and the supporting unit corresponds to the cutting table 36. During the upward movement of the sliding plate 20, the clamping unit can only be clamped in the wedge groove 34 of the topmost support seat 32, and the supporting unit can support the plate 31 on the cutting table 36.

[0049] The clamping unit includes a first slide plate 21, which is slidably arranged in the first slide groove of the sliding plate 20. The first slide plate 21 is connected to the sliding plate 20 by a second spring 25. A first wedge block 23 and a second wedge block 24 are fixed to the side of the first slide plate 21 opposite to the plate 31. The first wedge block 23 is located above the second wedge block 24. The end surfaces of the first wedge block 23 and the second wedge block 24 facing the plate 31 are both inclined surfaces, and the lower ends of the inclined surfaces are close to the first slide plate 21. The vertical distance between the first wedge block 23 and the second wedge block 24 is greater than the vertical distance between the upper groove wall of the wedge groove 34 and the upper end surface of the support seat 32.

[0050] The supporting unit includes a second slide plate 26, which is slidably arranged in the second slide groove of the sliding plate 20. A groove 27 is opened on the second slide plate 26, and a third spring 28 is installed in the groove 27. One end of the third spring 28 is fixedly connected to the second slide plate 26, and the other end of the third spring 28 is fixedly connected to the sliding plate 20. A support block 22 is fixed on the side of the second slide plate 26 opposite to the plate 31. A guide slope 30 is processed on the lower part of the side of the support block 22 away from the second slide plate 26, and the lower end of the guide slope 30 is close to the second slide plate 26.

[0051] For the convenience of description, the side where the second conveyor belt 29 is located is called the rear side, and the two rotating units are located on the left and right sides respectively.

[0052] like Fig. 9 As shown, in the initial state of the two sliding plates 20, the two sliding plates 20 are respectively located on the left and right sides of the base plate 1, the clamping unit and the supporting unit are respectively squeezed by the base plate 1 into the first sliding groove and the second sliding groove of the sliding plate 20, and the second spring 25 and the third spring 28 are compressed.

[0053] When the plate 31 needs to be cut, the motor 15 is started, and the motor 15 drives the fixed block 16 to rotate. When the fixed block 16 rotates, the slide bar 17 is driven to rotate around the axis of the motor 15. When the slide bar 17 rotates around the axis of the motor 15, the slide plate 20 moves upward through the connecting seat 18. At this time, the slide block 12 is blocked by the connecting rod 9 at the front side, and the slide plate 20 can only move upward along the axial direction of the vertical rod 13.

[0054] As the sliding plate 20 continues to move upward, when the sliding plate 20 moves to the outside of the support assembly, the support block 22 extends toward the cutting table 36 under the elastic force of the third spring 28. Fig.10 As shown, under the elastic force of the second spring 25 , the first wedge block 23 and the second wedge block 24 of the clamping unit are in sliding contact with the support seat 32 .

[0055] During the upward movement of the sliding plate 20 , when the second wedge block 24 corresponds to the wedge groove 34 , the first wedge block 23 above the second wedge block 24 is blocked by the support seat 32 , and the second wedge block 24 cannot enter the corresponding wedge groove 34 .

[0056] like Fig.11 As shown, since the vertical distance between the first wedge block 23 and the second wedge block 24 is greater than the vertical distance between the upper wall of the wedge groove 34 and the upper end surface of the support seat 32, when the second wedge block 24 corresponds to the wedge groove 34 of the uppermost support seat 32, the first wedge block 23 is not blocked. At this time, under the elastic force of the second spring 25, the first slide plate 21, the first wedge block 23 and the second wedge block 24 move toward the plate 31, and the second wedge block 24 is clamped in the wedge groove 34 of the uppermost support seat 32. In the subsequent upward movement of the sliding plate 20, the two uppermost support seats 32 and a plate 31 can be driven to move.

[0057] When the sliding plate 20 moves to the upper side of the vertical rod 13 and is blocked by the upper slider 12 , the slider 12 , the vertical rod 13 , the sliding plate 20 , the support seat 32 and the plate 31 can move backward in the axial direction of the crossbar 10 .

[0058] When the upper slider 12 is blocked by the rear connecting rod 9 , the slider 12 , the vertical rod 13 , the sliding plate 20 , the supporting seat 32 and the plate 31 can move downward in the axial direction of the vertical rod 13 .

[0059] When the plate 31 between the two supporting seats 32 is blocked by the cutting table 36 , the plate 31 gradually withdraws from between the two supporting seats 32 as the sliding plate 20 moves downward.

[0060] After the plate 31 withdraws from between the two support seats 32, during the downward movement of the sliding plate 20, the two support seats 32 and the two sliding plates 20 move downward together.

[0061] When the lower end of the support seat 32 contacts the first conveyor belt 3, the support seat 32 is blocked by the first conveyor belt 3. As the sliding plate 20 continues to descend, under the guidance of the lower groove wall of the wedge groove 34 and the upper inclined surface of the second wedge block 24, the two support seats 32 approach each other until the second wedge block 24 withdraws from the wedge groove 34.

[0062] As the sliding plate 20 continues to move downward, after the inclined surface of the second wedge block 24 contacts the upper edge of the bottom plate 1, under the guidance of the upper inclined surface of the second wedge block 24, the first wedge block 23, the second wedge block 24 and the first slide plate 21 move into the first slide groove, and the second spring 25 is compressed. After the guide slope 30 of the support block 22 contacts the upper edge of the bottom plate 1, under the guidance of the upper guide slope 30 of the support block 22, the support block 22 and the second slide plate 26 move into the second slide groove, and the third spring 28 is compressed. The sliding plate 20 returns to the initial state.

[0063] After the plate 31 is supported by the cutting table 36 , the plate 31 on the cutting table 36 is cut as required by controlling the first electric linear guide 5 , the second electric linear guide 7 and the cutting head 8 .

[0064] The main function of the support block 22 is to remove the plate 31 cut on the cutting table 36. For the convenience of description, the plate 31 cut on the cutting table 36 is called a finished plate.

[0065] In the subsequent process of the sliding plate 20 transferring the two uppermost support seats 32 and a plate 31 to the cutting table 36 through the clamping unit, after the support block 22 is located under the finished plate, as the sliding plate 20 moves upward, the support block 22 can support the finished plate, and the finished plate will move with the sliding plate 20.

[0066] When the finished board moves to the top of the second conveyor belt 29, the finished board can be supported by the second conveyor belt 29 during the downward movement of the sliding plate 20, and then the finished board is separated from the support block 22. The finished board is transferred from the cutting table 36 to the second conveyor belt 29, and the plate 31 is transferred to the cutting table 36. The cutting device can realize automatic loading and unloading.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
