Description

Technical Field

[0001] This invention belongs to the field of civil aircraft assembly and relates to a device for positioning the axes of multiple targets using laser. Background Technology

[0002] The baggage compartment, an essential structure for civil aircraft, is secured by baggage compartment brackets installed inside the fuselage bulkhead. These brackets, numerous in number and mounted on load-bearing frames within the fuselage bulkhead, significantly impact the installation and usability of the baggage compartment, making them a crucial parameter to ensure during assembly.

[0003] Currently, there are two common process methods: (1) When assembling the wall panel components, the baggage compartment bracket is positioned by tooling in the aircraft coordinate system and installed onto the wall panel to form a whole, ensuring the relative position of the bracket and the wall panel structure. Then, the whole fuselage barrel section is gradually assembled according to the assembly process of "wall panel - half shell - barrel section". (2) After the barrel section is formed, a coordinate system is established with the aircraft reference, and the baggage compartment bracket is positioned one by one using a laser tracker.

[0004] The problems with the two processes mentioned above are as follows: Although the former ensures accurate bracket positioning during the panel installation stage, assembly deformation and error accumulation inevitably occur as subsequent processes proceed, resulting in the coaxiality of the luggage compartment brackets exceeding the design allowable range after the final fuselage section is formed, causing rework; Although the latter can guarantee accuracy, due to the large product length and the fact that the installed parts are located inside the section, the laser tracker needs to be frequently rotated during operation, which is very inefficient. Taking a certain fuselage as an example, installing 24 luggage compartment brackets requires 3 people to work together and takes about 12 hours to complete. At the same time, the scarce resource of the laser tracker is occupied throughout the process. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention proposes a device for locating the axes of multiple targets using laser. This device uses a laser beam to simultaneously locate the axes of multiple luggage compartment supports after the fuselage section is formed, enabling convenient operation, eliminating the impact of assembly deformation and error accumulation, and reducing the occupation of scarce resources such as laser trackers.

[0006] The key technology of this invention is as follows: The device positions itself at both ends of the part to be mounted. By adjusting the laser beam generated by the laser emitter, it is kept in the theoretical position, replacing the traditional rigid tooling fixture positioner. An adapter sleeve matching the diameter of the laser beam is installed on the part to be mounted. By adjusting the part to be mounted so that the laser beam passes through the inner hole of the adapter sleeve, the coaxiality of the part to be mounted is ensured.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] like Figure 1As shown, a device for locating the axis of multiple targets using laser is disclosed. The device includes a positioning base plate assembly 01, a laser adjustment assembly 02, a locking assembly 03, an auxiliary support arm assembly 04, a target plate assembly 05, an adapter sleeve 06, a support assembly 07, and a laser emitter assembly 08. The basic working principle of the device is as follows: the device is positioned and installed to its theoretical position, with the target assembly 05 located at one end of the luggage compartment and the remaining components at the other end. By operating the adjustment assembly 02, the laser beam generated by the laser emitter assembly 08 is aimed at the target point on the target assembly 05, thus identifying the theoretical axis of the luggage compartment bracket. Installing the adapter sleeve 06 on the luggage compartment bracket and ensuring the laser beam passes through all the adapter sleeves 06 on the brackets before aiming at the target point guarantees the coaxiality of all luggage compartment brackets.

[0009] like Figure 2 As shown, the positioning base plate assembly 01 includes a positioning plate 01-01, a support arm 01-02, a connector 01-03, a support 01-04, a base plate 01-05, and a clamping positioning pin 01-06. The positioning plate 01-01 has round holes and oblong holes at both ends, which mate with the I-hole on the product frame at one end of the luggage compartment, and is fixed to the product frame by the positioning clamping pin 01-06. Two screw connectors 01-03 are provided, with their upper ends fixed to the outside of the positioning plate 01-01, and holes at their lower ends, with the hole axis parallel to the positioning plate 01-01. Two supports 01-04 are also provided, with one end inserted into the holes at the lower ends of the two screw connectors 01-03, allowing them to rotate around their axes within the holes, and the other end fixedly connected to the upper end of the base plate 01-05, enabling the base plate 01-05 to rotate around the axis of the support 01-04. The base plate 01-05 has several mounting holes for mounting the laser adjustment component 02, the auxiliary support arm component 04, and the support component 07, respectively. The upper end of the support arm 01-02 is fixedly connected to the positioning plate 01-01 and is located between the two screw joints 01-03. The lower end of the support arm has a threaded hole for mounting the locking component 03.

[0010] like Figure 3As shown, the laser adjustment assembly 02 includes a laser adjustment assembly base 02-01, a laser emitter mounting base 02-02, an X / Y adjustment platform 02-03, and a rotation adjustment platform 02-04. The laser adjustment assembly base 02-01 is used to fix the entire laser adjustment assembly 02 onto the base plate 01-05. The X / Y adjustment platform 02-03 is fixedly mounted on the laser adjustment assembly base 02-01 and has an X-axis adjustment handle 02-03-01 and a Y-axis adjustment handle 02-03-02 that are parallel to and perpendicular to the laser adjustment assembly base 02-01. The rotation adjustment platform 02-04 is fixedly connected to the X / Y adjustment platform 02-03 and has a rotation handle 02-04-01 on it. The laser emitter mounting base... 02-02 is fixedly connected to the rotary adjustment platform 02-04. Its upper end is provided with a clamping hole for positioning and clamping the laser emitter end 08-02 in the laser emitter assembly 08. The axis of the clamping hole is perpendicular to the positioning plate 01-01. By rotating the X-axis adjustment handle 02-03-01 or the Y-axis adjustment handle 02-03-02, the position of the laser emitter mounting base 02-02 in the horizontal or vertical direction can be adjusted. By rotating the rotary handle 02-04-01, the laser emitter mounting base 02-02 can be rotated. That is, by coordinating the operation of the X / Y adjustment platform 02-03 and the rotary adjustment platform 02-04, the position of the laser beam emitted by the laser emitter end 08-02 can be adjusted so that the laser beam coincides with the theoretical axis of the luggage compartment bracket.

[0011] like Figure 4 As shown, the locking assembly 03 includes a base 03-01, a top block 03-02, a pressure block 03-03, a screw 03-04, and a nut 03-05. The bottom surface of the base 03-01 is fixed to the base plate 01-05, and a conical groove is formed on its upper surface. The top block 03-02 has a hemispherical head, which is placed in the conical groove of the base 03-01. The pressure block 03-03 is fixedly connected to the base 03-01, restricting the top block 03-02 in the conical groove of the base 03-01, and ensuring that the head of the top block 03-02 always abuts against the conical surface of the conical groove of the base 03-01. A through hole is formed in the middle of the pressure block 03-03 for screw threading. Rod 03-04 passes through; the screw 03-04 passes through the threaded hole B on the support arm 01-02 and the through hole of the pressure block 03-03 in sequence, and is fixedly connected to the tail end of the top block 03-02, and the screw 03-04 is threadedly engaged with the support arm 01-02; two nuts 03-05 are provided, which are sleeved on the screw 03-04 and located on both sides of the support arm 01-02 respectively. Rotating the screw 03-04 will push the top block 03-02 through the displacement of the screw 03-04, thereby driving the base 03-01 to drive the base plate 01-05 to rotate around the axis of the support 01-04. After adjusting to the correct position, it is locked by the nuts 03-05.

[0012] like Figure 5 As shown, the auxiliary support arm assembly 04 includes a support corner bracket 04-01, a connecting plate A 04-02, a corner bracket 04-03, a clamping threaded pin A 04-04, and a handle nut A 04-05, used to assist in supporting and fixing the entire device. One end of the support corner bracket 04-01 is installed on the base plate 01-05; one end of the connecting plate A 04-02 is connected to the other end of the support corner bracket 04-01 via the clamping threaded pin A 04-04. After the other end of the connecting plate A 04-02 is assembled with the corner bracket 04-03 as a whole, it is positioned and fixed to the adjacent product frame by the clamping threaded pin A 04-04 and the handle nut A 04-05.

[0013] like Figure 8 As shown, the support assembly 07 includes a connecting plate B 07-01, a connecting angle rod 07-02, and a support box 07-03. The connecting plate B 07-01 is installed on the base plate 01-05. The connecting angle rod 07-02 is used to connect the upper connecting plate B 07-01 and the lower support box 07-03. The support box 07-03 is used to place the laser transmitter host 08-01 in the laser transmitter assembly 08. If necessary, a telescope is installed on the support assembly 07 to observe the laser beam accurately aiming at the target point E.

[0014] like Figure 9 As shown, the laser emitter assembly 08 includes a laser emitter main unit 08-01, a laser emitter end unit 08-02, and a transmission line 08-03; the transmission line 08-03 connects the laser emitter main unit 08-01 and the laser emitter end unit 08-02. The laser emitter main unit 08-01 is fixed inside the support box 07-03, and the laser emitter end unit 08-02 is clamped in the laser emitter mounting base 02-02 for emitting a laser beam.

[0015] like Figure 6 As shown, the target plate assembly 05 includes a positioning arm 05-01, a positioning block 05-02, a target plate 05-03, a clamping threaded pin B 05-04, and a handle nut B 05-05. The positioning arm 05-01 is positioned by the positioning block 05-02 at one end, and its other end is fixed to the corresponding product frame at the other end of the luggage compartment by the clamping threaded pin B 05-04 and the handle nut B 05-05, thereby positioning and fixing the target plate assembly 05 in the correct position. The target plate 05-03 is fixedly connected to the positioning arm 05-01 and is marked with a target point E, which is used to receive the laser beam generated by the laser emitter assembly 08 and guide the laser beam to adjust to the theoretical axis position through the target point E.

[0016] like Figure 7As shown, the adapter sleeve 06 has stepped through holes, which are provided in several places and are respectively installed in the bearing holes of each luggage compartment bracket to be positioned and installed, so as to convert the bearing holes on the luggage compartment bracket into small holes to cooperate with the laser beam.

[0017] When using this invention:

[0018] The device for locating multiple targets using laser positioning is positioned and installed in its theoretical location. Target component 05 is located at one end of the luggage compartment, while the remaining components are located at the other end. By operating and adjusting component 02, the laser beam generated by laser emitting component 08 is aimed at the target point on target component 05. This laser beam then represents the theoretical axis of the luggage compartment bracket to be positioned. Adapter sleeves 06 are installed on the luggage compartment brackets, and the laser beam is directed through all the adapter sleeves 06 on all the brackets before aiming at target point E, thus ensuring the coaxiality of all luggage compartment brackets. Specifically:

[0019] First, before the device is put into use, rotate the screw 03-04 in the locking assembly. This rotates the base 03-01 via the top block 03-02, which in turn rotates the base plate 01-05 around the axis of the support 01-04. This allows for angle adjustment of the base plate 01-05, ensuring that the axis of the clamping hole on the laser emitter mounting base 02-02 is perpendicular to the positioning plate 01-01. The device is then locked in place using the nut 03-05. Using the I-hole on the product frame, and through the round and oblong holes on the positioning plate 01-01, the device is positioned and installed to its theoretical position using the positioning clamping pin 01-06. The support angle seat 04-01 on the auxiliary support arm assembly 04 is then installed on the base plate 01-05. The other end of the angle seat 04-03 is installed on the adjacent frame using the clamping threaded pin A 04-04 and the handle nut A 04-05 to improve the stability of the device.

[0020] Position and install the target plate assembly 05 onto the product frame at the other end of the luggage compartment, as shown in Figure 10. Specifically, position the positioning arm 05-01 in the target plate assembly 05 using the positioning block 05-02, and fix it to the theoretical position on the corresponding product frame at the other end of the luggage compartment using the clamping threaded pin B 05-04 and the handle nut B05-05.

[0021] Fix the laser emitter main unit 08-01 of the laser emitter assembly 08 inside the support box 07-03, and clamp the laser emitter end 08-02 into the clamping hole of the laser emitter mounting base 02-02. Connect the laser emitter main unit 08-01 to the power supply and start it. The laser emitter end 08-02 emits a laser beam. By operating the laser adjustment assembly 02, the laser beam is accurately aimed at the target point E on the target plate assembly 05. Specifically, by rotating the X-axis adjustment handle 02-03-01 and the Y-axis adjustment handle 02-03-02 respectively, and rotating the handle 02-04-01, the X / Y adjustment platform 02-03 and the rotation adjustment platform 02-04 are coordinated to make the laser beam accurately aim at the target point E on the target plate assembly 05. See Figure 11 .

[0022] Install the adapter sleeve 06 into the bearing holes of all the luggage compartment brackets to be installed. Install each luggage compartment bracket into its corresponding position on the laser beam path. Adjust the position of the luggage compartment brackets so that the laser beam passes through the inner holes of the adapter sleeve 06 on all luggage compartment brackets and aims at target point E on the target plate assembly 05. See Figure 12 At this point, all luggage compartment supports are coaxial.

[0023] The beneficial effects of this invention are:

[0024] This invention is a device that uses a laser beam to simultaneously position multiple supports after the fuselage section is formed, thereby eliminating the effects of assembly deformation and error accumulation, and ensuring coaxiality. This device is lightweight and easy to operate, and in addition to being used for positioning luggage compartment supports, it can also be applied to other multi-target positioning scenarios with coaxiality requirements.

[0025] This device can reduce the need for tooling fixtures and greatly improve work efficiency. Taking the fuselage work package in the A220 project as an example, the original plan required 3 operators to spend about 12 hours to complete the installation of each aircraft using a laser tracker. After adopting this device, it only requires 2 people to complete the installation in 4 hours, saving 28 man-hours per aircraft, while also avoiding the occupation of the laser tracker.

[0026] This device is used for luggage compartment bracket installation and has the following technical advantages:

[0027] (1) One set of tooling can be adapted to multiple machine body work packages. Within the effective range of the laser, the number of positioned parts is unlimited. The tooling is versatile and highly applicable.

[0028] (2) After the fuselage is fully assembled, the baggage compartment bracket is positioned and installed based on the key features of the aircraft to avoid the effects of assembly deformation and error accumulation;

[0029] (3) It replaces the traditional rigid tooling frame positioner. Especially for semi-enclosed structures such as machine body barrel sections that cannot use tooling frames, this device can be positioned at both ends of the installed parts to achieve axial positioning of all parts in the middle area.

Detailed Implementation

[0044] The invention will now be described in further detail, but this should not be construed as limiting the invention in any way.

[0045] The following describes the installation process of the baggage compartment bracket in the fuselage work bag of the A220 as an example to illustrate this device in detail.

[0046] like Figure 1 As shown, a device for positioning the axis of multiple targets using laser is disclosed. The device includes a positioning base plate assembly 01, a laser adjustment assembly 02, a locking assembly 03, an auxiliary support arm assembly 04, a target plate assembly 05, an adapter sleeve 06, a support assembly 07, and a laser emitter assembly 08.

[0047] like Figure 2As shown, the positioning base plate assembly 01 includes a positioning plate 01-01, a support arm 01-02, a connector 01-03, a support 01-04, a base plate 01-05, and a clamping positioning pin 01-06. The positioning plate 01-01 has round holes and oblong holes at both ends, which mate with the I-hole on the product frame at one end of the luggage compartment, and is fixed to the product frame by the positioning clamping pin 01-06. Two screw connectors 01-03 are provided, with their upper ends fixed to the outside of the positioning plate 01-01, and holes at their lower ends, with the hole axis parallel to the positioning plate 01-01. Two supports 01-04 are also provided, with one end inserted into the holes at the lower ends of the two screw connectors 01-03, allowing them to rotate around their axes within the holes, and the other end fixedly connected to the upper end of the base plate 01-05, enabling the base plate 01-05 to rotate around the axis of the support 01-04. The base plate 01-05 has several mounting holes, including mounting hole A for mounting laser adjustment component 02, mounting hole C for mounting auxiliary support arm component 04, and mounting hole D for mounting support component 07; the upper end of the support arm 01-02 is fixedly connected to the positioning plate 01-01, located between two screw joints 01-03, and its lower end has a threaded hole B for mounting locking component 03.

[0048] like Figure 3 As shown, the laser adjustment assembly 02 includes a laser adjustment assembly base 02-01, a laser emitter mounting base 02-02, an X / Y adjustment platform 02-03, and a rotation adjustment platform 02-04. The laser adjustment assembly base 02-01 is used to fix the entire laser adjustment assembly 02 onto the base plate 01-05. The X / Y adjustment platform 02-03 is fixedly mounted on the laser adjustment assembly base 02-01 and has an X-axis adjustment handle 02-03-01 and a Y-axis adjustment handle 02-03-02 that are parallel to and perpendicular to the laser adjustment assembly base 02-01.

The laser emitter mounting base... 02-02 is fixedly connected to the rotary adjustment platform 02-04. Its upper end is provided with a clamping hole for positioning and clamping the laser emitter end 08-02 in the laser emitter assembly 08. The axis of the clamping hole is perpendicular to the positioning plate 01-01. By rotating the X-axis adjustment handle 02-03-01 or the Y-axis adjustment handle 02-03-02, the position of the laser emitter mounting base 02-02 in the horizontal or vertical direction can be adjusted. By rotating the rotary handle 02-04-01, the laser emitter mounting base 02-02 can be rotated. That is, by coordinating the operation of the X / Y adjustment platform 02-03 and the rotary adjustment platform 02-04, the position of the laser beam emitted by the laser emitter end 08-02 can be adjusted so that the laser beam is coaxial with the theoretical axis of the luggage compartment bracket.

[0049] like Figure 4 As shown, the locking assembly 03 includes a base 03-01, a top block 03-02, a pressure block 03-03, a screw 03-04, and a nut 03-05.

Rotating the screw 03-04 will push the top block 03-02 through the displacement of the screw 03-04, thereby driving the base 03-01 to drive the base plate 01-05 to rotate around the axis of the support 01-04. After adjusting to the correct position, it is locked by the nuts 03-05.

[0050] like Figure 5 As shown, the auxiliary support arm assembly 04 includes a support corner bracket 04-01, a connecting plate A 04-02, a corner bracket 04-03, a clamping threaded pin A 04-04, and a handle nut A 04-05, used to assist in supporting and fixing the entire device.

[0051] like Figure 8 As shown, the support assembly 07 includes a connecting plate B 07-01, a connecting angle rod 07-02, and a support box 07-03. The connecting plate B 07-01 is installed on the base plate 01-05. The connecting angle rod 07-02 is used to connect the upper connecting plate B 07-01 and the lower support box 07-03. The support box 07-03 is used to place the laser transmitter host 08-01 in the laser transmitter assembly 08. A telescope is installed on the support assembly 07 to observe the laser beam accurately aiming at the target point E.

[0052] like Figure 9As shown, the laser emitter assembly 08 includes a laser emitter main unit 08-01, a laser emitter end unit 08-02, and a transmission line 08-03; the transmission line 08-03 connects the laser emitter main unit 08-01 and the laser emitter end unit 08-02. The laser emitter main unit 08-01 is fixed inside the support box 07-03, and the laser emitter end unit 08-02 is clamped in the laser emitter mounting base 02-02 for emitting a laser beam.

[0053] like Figure 6 As shown, the target plate assembly 05 includes a positioning arm 05-01, a positioning block 05-02, a target plate 05-03, a clamping threaded pin B 05-04, and a handle nut B 05-05. The positioning arm 05-01 is positioned by the positioning block 05-02 at one end, and its other end is fixed to the corresponding product frame at the other end of the luggage compartment by the clamping threaded pin B 05-04 and the handle nut B 05-05, thereby positioning and fixing the target plate assembly 05 in the correct position. The target plate 05-03 is fixedly connected to the positioning arm 05-01 and is marked with a target point E, which is used to receive the laser beam generated by the laser emitter assembly 08 and guide the laser beam to adjust to the theoretical axis position through the target point E.

[0054] like Figure 7 As shown, the adapter sleeve 06 has a stepped through hole, which has several holes. These holes are installed in the bearing holes of the luggage compartment brackets to be positioned and installed, converting the Φ8mm bearing holes on the luggage compartment brackets into Φ3mm holes for use with the laser beam.

[0055] When using this invention:

[0056] The device for locating multiple targets using laser positioning is positioned and installed in its theoretical location. Target component 05 is located at one end of the luggage compartment, while the remaining components are located at the other end. By operating and adjusting component 02, the laser beam generated by laser emitting component 08 is aimed at the target point on target component 05. This laser beam then represents the theoretical axis of the luggage compartment bracket to be positioned. Adapter sleeves 06 are installed on the luggage compartment brackets, and the laser beam is directed through all the adapter sleeves 06 on all the brackets before aiming at target point E, thus ensuring the coaxiality of all luggage compartment brackets. Specifically:

[0057] First, before the device is put into use, rotate the screw 03-04 in the locking assembly. This rotates the base 03-01 via the top block 03-02, which in turn rotates the base plate 01-05 around the axis of the support 01-04. This allows for angle adjustment of the base plate 01-05, ensuring that the axis of the clamping hole on the laser emitter mounting base 02-02 is perpendicular to the positioning plate 01-01. The device is then locked in place using the nut 03-05. Using the I-hole on the product frame, and through the round and oblong holes on the positioning plate 01-01, the device is positioned and installed to its theoretical position using the positioning clamping pin 01-06. The support angle seat 04-01 on the auxiliary support arm assembly 04 is then installed on the base plate 01-05. The other end of the angle seat 04-03 is installed on the adjacent frame using the clamping threaded pin A 04-04 and the handle nut A 04-05 to improve the stability of the device.

[0058] Position and install the target plate assembly 05 onto the product frame at the other end of the luggage compartment, as shown in Figure 10. Specifically, position the positioning arm 05-01 in the target plate assembly 05 using the positioning block 05-02, and fix it to the theoretical position on the corresponding product frame at the other end of the luggage compartment using the clamping threaded pin B 05-04 and the handle nut B05-05.

[0059] Fix the laser emitter main unit 08-01 of the laser emitter assembly 08 inside the support box 07-03, and clamp the laser emitter end 08-02 into the clamping hole of the laser emitter mounting base 02-02. Connect the laser emitter main unit 08-01 to the power supply and start it. The laser emitter end 08-02 emits a laser beam. By operating the laser adjustment assembly 02, the laser beam is accurately aimed at the target point E on the target plate assembly 05. Specifically, by rotating the X-axis adjustment handle 02-03-01 and the Y-axis adjustment handle 02-03-02 respectively, and rotating the handle 02-04-01, the X / Y adjustment platform 02-03 and the rotation adjustment platform 02-04 are coordinated. Observe through the telescope mounted on the support assembly 07 to ensure that the laser beam is accurately aimed at the target point E on the target plate assembly 05. See Figure 11 .

[0060] Install the adapter sleeve 06 into the bearing holes of all the luggage compartment brackets to be installed. Install each luggage compartment bracket into its corresponding position on the laser beam path. Adjust the position of the luggage compartment brackets so that the laser beam passes through the inner holes of the adapter sleeve 06 on all luggage compartment brackets and aims at target point E on the target plate assembly 05. See Figure 12 At this point, all luggage compartment brackets are coaxial. After the luggage compartment brackets on this axis are installed, the device is then...

[0061] The above-described embodiments are merely illustrative of the implementation methods of the present invention, but should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
