Description

Technical Field

[0001] The present invention belongs to the technical field of drilling and riveting machines, and particularly relates to a flexible positioning tooling for wall panels used in drilling and riveting. Background Art

[0002] Aircraft wall panels usually have the characteristics of large size, large curvature, and complex structure, which makes it difficult for traditional manual assembly methods to meet the requirements of high precision and high efficiency. Therefore, automatic drilling and riveting technology has emerged to improve the assembly quality and efficiency. The wall panel positioning component is one of the important parts to ensure the riveting accuracy. In order to improve the positioning accuracy and assembly efficiency, the design of the positioning part has been continuously optimized and improved. Currently, advanced structural design technology, control technology, and measurement and detection technology are commonly used, but there is a lack of a more accurate and economical positioning component technology for the fixed positioning components of the wall panel itself.

[0003] Publication No. JP2005183383A discloses a positioning part for a riveting bracket. When riveting an H-type press-fit connector, the H-type press-fit connector can be accurately positioned on the riveting bracket, and positioning can be provided to make the possibility of caulking failure extremely small for the riveting bracket. Solution: The riveting bracket of the press-fit connector is provided with a first part and a second part. The first part is the part that connects the riveting bracket to the riveting tool of the riveted connector. The second part is connected to the first part and is the part that fills the connector. In addition, in the first part, a positioning part for the riveting bracket is installed. This patent still has room for improvement.

[0004] It should be noted that the above introduction of the technical background is only for the convenience of clearly and completely explaining the technical solution of the present application and facilitating the understanding of those skilled in the art. It cannot be considered that the above technical solutions are well-known to those skilled in the art just because these solutions are described in the background art part of the present application. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, the present invention provides a flexible positioning tooling for wall panels used in drilling and riveting, which is used for the installation, fixation, and drilling and riveting requirements of multiple wall panels. The device sets the traveling gear below the slide rail, and through the design of the upper and lower sliders, the vibration of the wall panel caused by the rolling of the gear and the short-distance up and down displacement in the z-axis direction can be eliminated, effectively solving the problem of interference in the riveting area of the wall panel and improving the automation drilling and riveting rate.

[0006] To solve the above technical problems, the present invention specifically provides the following technical solutions:

[0007] The flexible positioning tooling for drilling and riveting of wall panels includes a clamping plate installation component and a wall panel clamping device installed in cooperation with the clamping plate installation component. The clamping plate installation component includes a moving mechanism bottom plate. On one side of the moving mechanism bottom plate, there is a second servo reduction motor. One end of the second servo reduction motor is fixedly connected with a traveling gear, and a traveling slide rail is in rolling cooperation above the traveling gear.

[0008] According to an embodiment of the present invention, on one side of the moving mechanism bottom plate, there is a lifting slide rail having the same length as the moving mechanism bottom plate. The lifting slide rails are arranged in a pair and at an interval. At the bottom end of the lifting slide rails, there is a lower sealing plate, and at the top end of the lifting slide rails, there is an upper sealing plate. On the upper part of the lower sealing plate, there is a limiting block, which is arranged between the paired lifting slide rails. A lead screw is connected to the limiting block through a bearing. One end of the lead screw passes through a nut seat. There is a threaded hole on one side of the nut seat, and the lead screw is axially the same as the lifting slide rail. A first slider is movably clamped on the lifting slide rail, and there is a threaded hole on the first slider. On the side of the upper sealing plate away from the lifting slide rail, there is a first servo reduction motor, which is arranged perpendicular to the axis of the lifting slide rail. A lifting bracket is arranged outside the first slider, and the lifting bracket is fixedly connected to the first slider by threads.

[0009] The lead screw is arranged between the two lifting slide rails. The bottom end of the lead screw is connected to the limiting block, and the two can be connected through a bearing or other connection methods to enable the lead screw to rotate freely on the limiting block without causing lateral or longitudinal displacement between the lead screw and the limiting block. The other end of the lead screw is provided with a nut seat, and the lead screw can pass through the nut seat. There is a threaded hole on the nut seat, and there is a hole corresponding to the threaded hole on the lifting bracket, and the two are fixedly installed. Since the nut seat can move but not rotate, when the lead screw rotates, it can drive the nut seat to achieve vertical displacement. There are several through holes on the lifting bracket, which correspond to the through holes on the first slider. The lifting bracket is fixedly installed with the first slider through the through holes. The first slider is arranged on the lifting slide rail, and the first slider can be arranged in one group or two groups to improve the connection stability between the first slider and the lifting bracket. The up-and-down smooth displacement of the lifting bracket is realized through the fixed installation of the lifting bracket, the first slider and the nut seat. The upper end of the lead screw is provided with a first servo reduction motor, which is arranged perpendicular to the axis of the lead screw, and the motor drives the lead screw to rotate through the way of gear meshing when the motor rotates, so as to control the rising speed or falling speed of the lifting bracket through the rotation direction and rotation speed of the motor. The design of the first slider, on the one hand, makes the up-and-down displacement of the lifting bracket smoother, achieves the effect of limiting in three-axis directions, and avoids rotational displacement of the lifting bracket. On the other hand, it can share the pressure at the connection part between the lifting bracket and the nut seat, increase the service life of the lifting bracket and the nut seat, and reduce wear.

[0010] According to one embodiment of the present invention, the end of the lifting bracket is connected to the main clamping plate, and an arc-shaped notch is provided at the connection position between the lifting bracket and the main clamping plate, and the arc-shaped notch is downwardly directed, and the wall panel clamping device includes a positioning pin, and the positioning pin is arranged on one side of the main clamping plate and is clamped with the arc-shaped notch. A through hole is provided on the main clamping plate, and a clamping bolt is provided on the side of the main clamping plate opposite to the positioning pin, and the clamping bolt passes through the through hole.

[0011] The lifting bracket is connected to the pallet, which is used to place the aircraft wall panels. Due to the differences in size, weight and other factors of the wall panel parts, it is usually necessary to replace the appropriate pallet according to the specifications of the wall panel parts, so the pallet needs to be frequently disassembled and assembled. The design of the wall panel clamping device greatly reduces the requirements for installation accuracy when installing the pallet. The positioning pin is overlapped with the arc-shaped notch on the lifting bracket, and then the clamping bolt is tightened to complete the installation of the pallet. Since the arc-shaped opening direction of the lifting bracket is upward, the pallet is overlapped on the arc-shaped notch in the direction of gravity, and the wall panel parts on the pallet will also give the pallet a downward force, so that the pallet cannot be separated from the arc-shaped notch. When disassembling or replacing the pallet, you only need to loosen the clamping bolt and lift the pallet upward. It is easy to disassemble and assemble, which reduces the time required to replace the pallet and greatly improves production efficiency.

[0012] According to one embodiment of the present invention, a second slider is provided on one side of the bottom plate of the motion mechanism, the second sliders are arranged in pairs, and the second sliders are arranged on the upper and lower sides of the travel gear. The second servo reduction motor passes through the bottom plate of the motion mechanism.

[0013] When the panel positioning member is working, it is mainly for the horizontal transportation task. There is a groove on the second slider, and a slideway corresponding to the groove is provided on the positioning member mounting frame, so that the second slider can be clamped on the slideway and can slide along the slide rail. The traveling gear is arranged at the lower part of the traveling slide rail, and a gear structure matching the traveling gear is provided at the bottom of the traveling slide rail. In this way, it is possible to eliminate the up-and-down shaking and left-and-right displacement of the panel caused by the rolling of the gear. The specific principle is as follows: When the traveling gear is on the upper side of the traveling slide rail, at this time the traveling gear is completely pressed on the traveling slide rail, and the moving mode of the traveling gear on the traveling slide rail is rolling. And because both the traveling gear and the traveling slide rail are non-cylindrical, the rolling track is not a straight line, but an undulating curve, resulting in the traveling gear driving the card plate mounting assembly and the card plate on it to have a slight up-and-down shaking. This shaking degree is relatively low, but for the high-precision requirements of the aircraft manufacturing industry, this shaking may cause a slight displacement of the aircraft panel, and then lead to a deviation in the punching and drill riveting positions. On the contrary, when the traveling gear is arranged at the lower part of the traveling slide rail, the second slider located below the traveling gear is tightly clamped with the slideway on the corresponding positioning member mounting frame. Due to the action of gravity, there is no gap between the bottom of the slideway and the bottom of the second slider at this time, and the traveling gear and the gear structure below the traveling slide rail do not completely contact. When the second servo reduction motor rotates at this time, it drives the traveling gear to rotate. Because the traveling gear and the gear structure below the traveling slide rail do not completely contact and there is no gap between the bottom of the slideway and the bottom of the second slider, the rolling track of the traveling gear is a straight line at this time, so as to eliminate the up-and-down shaking and left-and-right displacement of the panel caused by the rolling of the gear, and also reduce the wear between the gears.

[0014] The panel positioning member is usually an automated production line, but the card plate needs to be replaced manually, and the personnel need to select a suitable card plate according to the card plate category or specification, etc. Since there is no gap between the bottom of the slideway on the positioning member mounting frame and the bottom of the second slider, there is a large frictional force between the two. When the card plate specification matches the weight of the panel, the panel positioning device operates normally at this time; when the panel quality is too large and the card plate specification does not match the panel weight, it will cause the rotation speed of the second servo reduction motor to slow down, the frictional force between the bottom of the slideway on the positioning member mounting frame and the bottom of the second slider increases, and the moving speed of the panel positioning device slows down. The personnel can judge whether the personnel have forgotten to replace the card plate or whether the used card plate is correct according to the moving speed of the panel positioning device.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The design of the first slider, on the one hand, makes the up-and-down displacement of the lifting bracket smoother, achieving the effect of limiting in three-axis directions and preventing the lifting bracket from rotating and displacing. On the other hand, it can share the pressure at the connection part between the lifting bracket and the nut seat, increase the service life of the lifting bracket and the nut seat, and reduce wear. When disassembling or replacing the clamping plate, only need to loosen the compression bolt and lift the clamping plate upward, which is convenient for disassembly and assembly, reduces the time required for replacing the clamping plate, and greatly improves the production efficiency. It can eliminate the up-and-down shaking and left-and-right displacement of the wall plate caused by the rolling of the gear, avoid the wall plate from jolting, and personnel can judge whether they forget to replace the clamping plate or whether the used clamping plate is correct according to the movement speed of the wall plate positioning device.

[0030] First, the concepts involved in the present application will be described in conjunction with the accompanying drawings. It should be noted here that the following descriptions of each concept are only for making the content of the present application easier to understand, and do not represent a limitation on the protection scope of the present application; at the same time, without conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0031] Embodiment 1

[0032] See the attached Figures 1-10 As shown, the flexible positioning tooling for the wall plate in drilling and riveting includes a pallet mounting assembly 1 and a wall plate clamping device 2 that is cooperatively installed with the pallet mounting assembly 1. The pallet mounting assembly 1 includes a base plate 101 of the motion mechanism. A second servo reduction motor 110 is provided on one side of the base plate 101 of the motion mechanism. One end of the second servo reduction motor 110 is fixedly connected with a traveling gear 110a, and a traveling slide rail 112 is in rolling cooperation above the traveling gear 110a.

[0033] On one side of the base plate 101 of the motion mechanism, there is a lifting slide rail 104 that is as long as the base plate 101 of the motion mechanism. The lifting slide rails 104 are arranged in a pair and are spaced apart. At the bottom end of the lifting slide rails 104, there is a lower sealing plate 102, and at the top end of the lifting slide rails 104, there is an upper sealing plate 107. On the upper part of the lower sealing plate 102, there is a limit block 103. The limit block 103 is arranged between the paired lifting slide rails 104. A lead screw 105 is connected to the limit block 103 by a bearing. One end of the lead screw 105 passes through a nut seat 106. There is a threaded hole on one side of the nut seat 106. The lead screw 105 has the same axial direction as the lifting slide rails 104. A first slider 113 is movably clamped on the lifting slide rails 104, and there is a threaded hole on the first slider 113. On the side of the upper sealing plate 107 away from the lifting slide rails 104, there is a first servo reduction motor 109. The first servo reduction motor 109 is arranged perpendicular to the axis of the lifting slide rails 104. On the outside of the first slider 113, there is a lifting bracket 111. The lifting bracket 111 is fixedly connected to the first slider 113 by threads.

[0034] The lead screw 105 is arranged between two lifting slide rails 104. The bottom end of the lead screw 105 is connected to the limit block 103, and the two can be connected by a bearing or other connection methods to enable the lead screw 105 to rotate freely on the limit block 103 without causing lateral or longitudinal displacement of the lead screw 105 and the limit block 103. The other end of the lead screw 105 is provided with a nut seat 106. The lead screw 105 can pass through the nut seat 106. The nut seat 106 is provided with a threaded hole, and the lifting bracket 111 is provided with a hole corresponding to the threaded hole, and the two are fixedly installed. Since the nut seat 106 can move but not rotate, when the lead screw 105 rotates, it can drive the nut seat 106 to achieve vertical displacement. The lifting bracket 111 is provided with several through holes, which correspond to the through holes on the first slider 113. The lifting bracket 111 and the first slider 113 are fixedly installed through the through holes. The first slider 113 is arranged on the lifting slide rail 104, and the first slider 113 can be set to one group or two groups to improve the connection stability between the first slider 113 and the lifting bracket 111. The lifting bracket 111 achieves smooth vertical displacement through the fixed installation of the lifting bracket 111, the first slider 113, and the nut seat 106. The upper end of the lead screw 105 is provided with a first servo reduction motor 109. The motor is arranged perpendicular to the axial direction of the lead screw 105, and the rotation of the motor can drive the lead screw 105 to rotate through the meshing of gears, so as to control the rising speed or falling speed of the lifting bracket 111 by the rotation direction and rotation speed of the motor. The design of the first slider 113, on the one hand, makes the vertical displacement of the lifting bracket 111 smoother, achieving the effect of limiting in the three-axis direction and preventing the lifting bracket 111 from rotating and displacing. On the other hand, it can share the pressure at the connection part between the lifting bracket 111 and the nut seat 106, increase the service life of the lifting bracket 111 and the nut seat 106, and reduce wear. At the same time, it can ensure that the horizontal heights of the lifting brackets 111 installed on both sides of the lead screw 105 are the same without inclination, and also avoid inclination problems caused by the setting of other components on the lifting bracket 111, such as clamping plates, etc.

[0035] The end of the lifting bracket 111 is connected to the main clamping plate 3. An arc-shaped notch is provided at the connection position between the lifting bracket 111 and the main clamping plate 3, and the direction of the arc-shaped notch is downward. The wall plate clamping device 2 includes a positioning pin 201, and the positioning pin 201 is arranged on one side of the main clamping plate 3 and is clamped with the arc-shaped notch. The main clamping plate 3 is provided with a through hole, and a pressing bolt 202 is provided on the side of the main clamping plate 3 opposite to the positioning pin 201, and the pressing bolt 202 passes through the through hole.

[0036] The lifting bracket 111 is connected to the clamping plate. The clamping plate is used to place the aircraft panel. Due to differences in factors such as the size and weight of the panel parts, it is usually necessary to replace the appropriate clamping plate according to the specifications of the panel parts. Therefore, the clamping plate needs to be frequently disassembled and assembled. The design of the panel clamping device 2 greatly reduces the requirements for installation accuracy when installing the clamping plate. Align the positioning pin 201 with the arc-shaped notch on the lifting bracket 111, and then tighten the compression bolt 202 to complete the installation of the clamping plate. Since the opening direction of the arc of the lifting bracket 111 is upward, the clamping plate is lapped on the arc-shaped notch with the gravity direction downward, and the panel parts on the clamping plate will also apply a downward force to the clamping plate, preventing the clamping plate from detaching from the arc-shaped notch. When disassembling or replacing the clamping plate, just loosen the compression bolt 202 and lift the clamping plate upward. The disassembly and assembly are convenient, reducing the time required to replace the clamping plate and greatly improving production efficiency.

[0037] On one side of the moving mechanism bottom plate 101, there are second sliders 114. The second sliders 114 are arranged in pairs and are located on the upper and lower sides of the traveling gear 110a. The second servo reduction motor 110 passes through the moving mechanism bottom plate 101.

[0038] When the panel positioning member is working, it is mainly for the transportation task of lateral movement. There is a groove on the second slider 114, and a slideway corresponding to the groove is provided on the positioning member mounting frame 115, so that the second slider 114 can be clamped on the slideway and slide along the slide rail. The traveling gear 110a is arranged at the lower part of the traveling slide rail 112, and a gear structure matching the traveling gear 110a is provided at the bottom of the traveling slide rail 112. In this way, the up-and-down shaking and left-and-right displacement of the panel caused by the rolling of the gear can be eliminated. The specific principle is as follows: When the traveling gear 110a is located on the upper side of the traveling slide rail 112, at this time the traveling gear 110a is completely pressed on the traveling slide rail 112, and the moving mode of the traveling gear 110a on the traveling slide rail 112 is rolling. And because both the traveling gear 110a and the traveling slide rail 112 are non-cylindrical, the rolling track is not a straight line, but an undulating curve, resulting in the traveling gear 110a driving the card board mounting assembly 1 and the card board thereon to have a slight up-and-down shaking. This shaking degree is relatively low, but for the high-precision requirements of the aircraft manufacturing industry, this shaking may cause a slight displacement of the aircraft panel, and then lead to a deviation in the punching and drill riveting positions. On the contrary, when the traveling gear 110a is arranged at the lower part of the traveling slide rail 112, the second slider 114 located below the traveling gear 110a is tightly clamped with the slideway on the corresponding positioning member mounting frame 115. Due to the action of gravity, there is no gap between the bottom of the slideway and the bottom of the second slider 114 at this time, and the gear structure below the traveling gear 110a and the traveling slide rail 112 may not be in complete contact. At this time, when the second servo reduction motor 110 rotates, it drives the traveling gear 110a to rotate. Since the gear structure below the traveling gear 110a and the traveling slide rail 112 is not in complete contact and there is no gap between the bottom of the slideway and the bottom of the second slider 114, the rolling track of the traveling gear 110a is a straight line at this time, so as to eliminate the up-and-down shaking and left-and-right displacement of the panel caused by the rolling of the gear, and also reduce the wear between the gears.

[0039] The panel positioning member is usually an automated production line, but the card board needs to be replaced manually, and the personnel need to select a suitable card board according to the card board category or specification, etc. Since there is no gap between the bottom of the slideway on the positioning member mounting frame 115 and the bottom of the second slider 114, there is a large frictional force between the two. When the card board specification matches the weight of the panel, the panel positioning device operates normally at this time; when the panel quality is too large and the card board specification does not match the panel weight, it will cause the rotation speed of the second servo reduction motor 110 to slow down, the frictional force between the bottom of the slideway on the positioning member mounting frame 115 and the bottom of the second slider 114 increases, and the moving speed of the panel positioning device slows down. The personnel can judge whether the personnel forget to replace the card board or whether the used card board is correct according to the moving speed of the panel positioning device.
