Description

[0001] This application is a divisional application of the parent application filed on December 25, 2020, with application number 202011564023.7 and invention title "An Automatic Drilling and Riveting Device and Method". Technical Field

[0002] This invention relates to the field of automated machining technology, and in particular to an automatic drilling and riveting device and method. Background Technology

[0003] In recent years, with the continuous improvement of the performance requirements of aerospace products, achieving high-strength and lightweight manufacturing of structural components has become one of the urgent problems to be solved in the aerospace manufacturing field.

[0004] As a key task in weight-reduction structural design, skin-frame structures commonly employ riveting for their mechanical connections. Large panel-type parts, exemplified by skin-frame structures, often require hundreds or even thousands of rivets for assembly. However, in current production, riveting operations heavily rely on manual experience. The complete riveting process involves manual clamping, marking, drilling, countersinking, and riveting, requiring two people. This results in a lengthy process, low efficiency, and noise pollution, becoming a bottleneck in the product manufacturing process.

[0005] Therefore, in order to improve assembly efficiency and accuracy, it is necessary to optimize the current drilling and riveting process with intelligent design. Existing technologies include automatic drilling and riveting equipment for the short shells of launch vehicles, but this equipment can only drill and rivet cylindrical parts and cannot automatically drill and rivet large panel-like parts. Furthermore, the aforementioned automatic drilling and riveting equipment can only move up and down (i.e., along the Z-axis) and cannot achieve left and right or forward and backward movement (i.e., it cannot achieve movement along the X and Y axes).

Detailed Implementation

[0058] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0059] Example 1

[0060] One specific embodiment of the present invention discloses an automatic drilling and riveting device for large panel-like parts, such as... Figure 1 As shown. This large panel-type part refers to a part with a length greater than 2 meters and a width of 500-600 mm.

[0061] The automatic drilling and riveting device of this embodiment includes a tooling bracket unit 1, a first drive unit 2, a second drive unit 3, a third drive unit 4, a fourth drive unit 5, a fifth drive unit 6, a main body unit 7, a drilling unit 8, a pin insertion unit 9, a riveting unit 10, and a control system 11.

[0062] The connection relationships between the above units are as follows:

[0063] The first drive unit 2, the second drive unit 3, and the third drive unit 4 are all fixedly connected to the foundation.

[0064] The first drive unit 2, the second drive unit 3, the third drive unit 4, the fourth drive unit 5, the fifth drive unit 6, the main body unit 7, the drilling unit 8, the insertion unit 9, and the riveting unit 10 are all connected to the control system 11.

[0065] Both the fourth drive unit 5 and the fifth drive unit 6 are fixedly connected to the main body unit 7. Specifically, the third moving guide rail 24 of the fourth drive unit 5 is fixed to the main body 27 of the main body unit 7; the fourth moving guide rail 26 of the fifth drive unit 6 is fixed to the main body 27 of the main body unit 7.

[0066] The fuselage main body unit 7 and the first drive unit 2 are slidably connected via a guide rail slider. Specifically, the fuselage main body 27 of the fuselage main body unit 7 is slidably connected to the first moving guide rail 16 of the first drive unit 2 via a sliding pair.

[0067] The drilling unit 8 and the fourth drive unit 5 are slidably connected via a guide rail slider. Specifically, one end of the drilling base 30 of the drilling unit 8 is connected to the electric spindle mounting base 29, and the other end is slidably connected to the third moving guide rail 24 of the fourth drive unit 5.

[0068] The insertion unit 9 and the fifth drive unit 6 are slidably connected via a guide rail slider. Specifically, one end of the crossbeam 35 of the insertion unit 9 is fixedly connected to the insertion base 33, and the other end is slidably connected to the fourth moving guide rail 26 of the fifth drive unit 6.

[0069] The riveting unit 10 is fixedly connected to the main body unit 7. Specifically, the upper clamping component 36 and the lower clamping component 37 of the riveting unit 10 are both fixedly installed on the main body 27 of the main body unit 7 by screws.

[0070] The first drive unit 2, the second drive unit 3, the third drive unit 4 and the fourth drive unit 5 form a three-axis linkage to execute the instructions of the control system 11;

[0071] The first drive unit 2, the second drive unit 3, and the third drive unit 4 can also form a three-axis linkage with the fifth drive unit 6 to execute the instructions of the control system 11;

[0072] The control system 11 guides the automatic drilling and riveting equipment used for flat-head rivets to automatically drill, countersink, feed, insert, and rivet large panel parts, and also monitors the system's operating status.

[0073] The drilling unit 8 and the pin insertion unit 9 are located on both sides of the riveting unit 10, which can minimize the impact of riveting deformation on the accuracy of the device.

[0074] The following is combined Figures 1-7 Each unit of the automatic drilling and riveting device is described in detail.

[0075] like Figure 2As shown, the tooling bracket unit includes a bracket 12, a small pressure plate 13, a large pressure plate 14, and a support mechanism 38.

[0076] The bracket 12 is used to hold the fixture and the workpiece to be processed. Two support mechanisms 38 are located below both ends of the bracket 12 to support it. The bracket 12 is connected to the second drive unit 3 and the third drive unit 4 via the two support mechanisms 38. Specifically, the lower ends of the two support mechanisms 38 are slidably connected to the second drive unit 3 and the third drive unit 4 via sliding pairs, that is, the second drive unit 3 and the third drive unit 4 are located on the left and right sides of the tooling bracket unit 1, respectively, and are arranged symmetrically.

[0077] Both the small pressure plate 13 and the large pressure plate 14 are located on the upper surface of the bracket 12 and are fixedly connected to the bracket 12 by screws for fixing and clamping the workpiece to be processed.

[0078] The small pressure plate 13 and the large pressure plate 14 have the same length, which is equal to the width of the bracket 12. The width of the large pressure plate 14 is greater than the width of the small pressure plate 13.

[0079] The number of small pressure plates 13 and large pressure plates 14 can be flexibly adjusted according to the length of the workpiece to be processed. In one possible implementation, in order to better fix the large panel-like parts to be drilled and riveted, there are multiple small pressure plates 13 and large pressure plates 14. For example, there are two small pressure plates 13 and two large pressure plates 14.

[0080] Since the width of the large pressure plate 14 is greater than the width of the small pressure plate 13, in order to better flatten the workpiece, along the length of the bracket 12, the two small pressure plates 13 are located on both sides, and the two large pressure plates 14 are positioned between the two small pressure plates 13, as shown below. Figure 2 As shown.

[0081] In another possible implementation, the tooling bracket unit further includes limiting blocks (not shown) for positioning the workpiece. Exemplarily, these limiting blocks can be located at both ends of the upper surface of the bracket 12. Alternatively, corresponding limiting blocks can be set according to the characteristics of the workpiece, and the positions of the limiting blocks can be flexibly adjusted.

[0082] Next reference Figure 3 The first driving unit 2 will be described in detail.

[0083] like Figure 3 As shown, the first drive unit 2 is used to drive the main body unit 7 to move along the X-axis, and includes a first fixed base 15, a first moving guide rail 16, a first transmission screw 17 and a first drive motor 18.

[0084] The first fixed base 15 is fixed to the foundation by anchor bolts and leveling shims. The first moving guide rail 16 is fixed to the first fixed base 15 by screws. The first drive motor 18 is fixed to the first fixed base 15 by screws. The first transmission screw 17 is connected to the output shaft of the first drive motor 18 to drive the main body unit 7 to move along the X-axis.

[0085] The second drive unit 3 is used to drive the tooling bracket unit 1 to move along the Y-axis, and includes a second fixed base 19, a second moving guide rail 20, a second transmission screw 21, and a second drive motor 22. Figure 4 As shown, the second fixed base 19 is fixed to the foundation by anchor bolts and leveling shims, the second moving guide rail 20 is fixed to the second fixed base 19 by screws, the second drive motor 22 is fixed to the second fixed base 19 by screws, and the second transmission screw 21 is connected to the output shaft of the second drive motor 22 to drive the tooling bracket unit 1 to move along the Y-axis.

[0086] It should be noted that in this embodiment, the third drive unit 4 functions the same as the second drive unit 3, which is also used to drive the tooling bracket unit 1 to move along the Y-axis. Therefore, the composition of the third drive unit 4 can be the same as that of the second drive unit 3.

[0087] The fourth drive unit 5 is used to drive the drilling unit 8 to move along the third moving guide rail 24 (i.e., move along the Z-axis). It includes a third drive motor 23, a third moving guide rail 24, and a third transmission screw. The third transmission screw is connected to the output shaft of the third drive motor 23 to drive the drilling unit 8 to move along the third moving guide rail 24. Figure 5 As shown.

[0088] like Figure 6 As shown, the fifth drive unit 6 is used to drive the pin insertion unit 9 to move along the fourth moving guide rail 26. It includes a fourth drive motor 25, a fourth moving guide rail 26 and a fourth transmission screw. The fourth transmission screw is connected to the output shaft of the fourth drive motor 25 to drive the pin insertion unit 9 to move along the fourth moving guide rail 26.

[0089] The main body unit 7 is used for fixing and installing the device, and includes the main body 27. The main body 27 is slidably connected to the first moving guide rail 16 through a sliding pair, and the main body 27 moves along the first moving guide rail 16.

[0090] Continue to refer to Figure 5 The drilling unit 8 is used for automatic drilling of the product to be processed. It includes an electric spindle 28, an electric spindle mounting base 29, and a drilling base 30. The electric spindle 28 is fixedly mounted on the electric spindle mounting base 29, and the electric spindle mounting base 29 is fixedly mounted on the drilling base 30. The drilling base 30 is slidably connected to the third moving guide rail 24.

[0091] It should be noted that the electric spindle 28 can be used with drilling tools of different specifications to complete the machining of holes of different diameters.

[0092] Continue to refer to Figure 6 The pin insertion unit 9 is used for automatic pin insertion in holes and includes a pin feeding guide 31, a pin insertion guide 32, a pin insertion base 33, a cable bracket 34, and a crossbeam 35. The pin feeding guide 31 is fixedly connected to the pin insertion base 33, the pin insertion guide 32 is fixedly connected to the pin insertion base 33, the pin insertion base 33 is fixedly connected to one end of the crossbeam 35, the other end of the crossbeam 35 is slidably connected to the fourth moving guide rail 26, and the cable bracket 34 is fixedly connected to the crossbeam 35 and serves as a cable support.

[0093] The rivet feeding guide 31 is connected to the rivet feeding disc (not shown in the figure). Different rivet feeding discs can be set according to the different specifications of the holes to be riveted. The rivet feeding disc feeds out rivets of different specifications and reaches the end of the rivet feeding guide 31. The rivet receiving mechanism (not shown in the figure) inserts the rivet into the hole to be riveted through the rivet insertion guide 32 under system control.

[0094] It should be noted that, in order to ensure that the rivet is perpendicular to the hole to be riveted, the rivet guide tube 32 in this embodiment is configured to have a guiding function.

[0095] like Figure 7 As shown, the riveting unit 10 is used for automatic riveting of holes, including an upper clamping component 36 and a lower clamping component 37. The upper clamping component 36 is fixedly installed on the main body 27 of the machine body by screws, and the lower clamping component 37 is fixedly installed on the main body 27 of the machine body by screws.

[0096] It is worth noting that the clamping heads of the upper clamping component 36 and the lower clamping component 37 can be adjusted according to the different rivet specifications in order to complete the riveting of rivets of different specifications.

[0097] Considering that some parts to be processed have a certain curvature, the tooling bracket unit needs to be able to adjust its posture. In a preferred embodiment, the automatic drilling and riveting device also includes a bracket posture adjustment system. This bracket posture adjustment system includes four POGO pillars. The four POGO pillars have similar structures and serve as the posture adjustment carrier for the bracket.

[0098] By replacing the support mechanism 38 in the tooling bracket unit with four POGO columns, it is possible to move the bracket in the Z direction, rotate it around the X axis, and rotate it around the Y axis.

[0099] Four POGO posts are located below the bracket and are placed vertically to support the bracket. Specifically, the four POGO posts are located at the four corners of the rectangular bracket.

[0100] In a preferred embodiment, each of the four POGO pillars has a scale (not shown in the figure). By setting the scale, with the height of one POGO pillar fixed, the other three POGO pillars can be initially set to the same height as the first POGO pillar, and then their heights can be finely adjusted as needed. Alternatively, based on the curved shape of the workpiece, it can be determined whether the height of the other three POGO pillars should be higher or lower than the height of the first POGO pillar, and by how much higher or lower, thereby quickly adjusting the other three POGO pillars to the appropriate height.

[0101] In addition, level detectors are installed on the edges of the bracket in both the length and width directions on the upper surface, which can detect whether the bracket is level.

[0102] Compared with the prior art, the automatic drilling and riveting device of the present invention has the following advantages:

[0103] (1) The present invention sets up a first driving unit, which is configured as a specific component (including a first fixed base, a first moving guide rail, a first transmission screw and a first driving motor), and slides the main body unit with the first driving unit to realize the movement of the main body unit along the X-axis.

[0104] (2) By setting up a second drive unit and a third drive unit, the present invention sets the second drive unit and the third drive unit as specific components (including a second fixed base, a second moving guide rail, a second transmission screw and a second drive motor), and slides the tooling bracket unit with the second drive unit and the third drive unit to realize the movement of the tooling bracket unit along the Y-axis.

[0105] (3) By setting a fifth drive unit, the present invention sets the fifth drive unit as a specific component (including a fourth drive motor, a fourth moving guide rail and a fourth transmission screw), and slides the pin unit to the fifth drive unit to realize the movement of the pin unit along the Z-axis.

[0106] (4) By setting up the main body unit, the fixing and installation of the riveting device is realized.

[0107] (5) By setting up a drilling unit, the present invention realizes automatic drilling and countersinking of the product to be processed by setting the drilling unit as a specific component (including an electric spindle, an electric spindle mounting base and a drilling base).

[0108] (6) By setting up a pin insertion unit, the present invention realizes automatic pin insertion into the hole position by setting the pin insertion unit as a specific component (including a pin feeding guide, a pin insertion guide, a pin insertion base, a cable bracket and a crossbeam).

[0109] (7) By setting up a riveting unit, the present invention achieves automatic riveting of holes by setting the riveting unit as a specific component (including an upper pressing component and a lower pressing component).

[0110] (8) The present invention can realize the drilling, countersinking and riveting of large wall panel parts in one step. Through the control system, the system units can be controlled with high precision, and the workpiece can be processed with high precision.

Then, the rivet insertion unit inserts rivets of different specifications into the corresponding rivet holes until the rivet insertion work of all rivet holes is completed.

[0116] Step 4: Complete the riveting. First, the riveting program is executed through the control system. The upper clamping component presses the rivet head, and then the lower clamping component extends the clamping head upward to complete the riveting. This process continues until all rivets are riveted.

[0117] Step 5: The system returns to its initial position. After riveting is completed, the control system program is executed. The first drive unit, the second drive unit, the third drive unit, the fourth drive unit and the fifth drive unit form a five-axis linkage. Each unit of the system returns to its initial position to process the next workpiece and repeats steps 1 to 5.

[0118] In step 1, determine whether the bracket needs to be level based on the shape of the part. If the bracket needs to be level, this can be determined by observing a leveling instrument located at the edges of the bracket's length and width directions on its upper surface.

[0119] If the bracket is not level, you can quickly adjust the height of the four POGO posts using the markings on them, and then observe the level gauge until it shows that the bracket is level.

[0120] Compared with the prior art, the automatic drilling and riveting method of the present invention is simple and easy to implement, and has the advantages of high processing accuracy, high drilling and riveting efficiency, and high degree of automation. It can be widely used in the automated operation of similar structural parts, thus improving the level of intelligence.

[0121] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
