DETAILED DESCRIPTION

[0030] The present invention will be described in detail below with reference to the accompanying drawings by means of exemplary embodiments of the present invention. It should be noted that the following detailed description of the present invention is only for the purpose of illustration, and is not intended to limit the present invention.

[0031] The utility model provides a multi-freedom flexible platform, which is used for cooperating with an elevator to assemble supported aviation products to their counterparts, and can realize multi-freedom adjustment of the supported objects in front, back, left, right and deflection, and can also realize a flexible docking support mode.

[0032] The multi-degree-of-freedom flexible platform provided by the utility model is now described in detail.

[0033] First, the overall reference Figure 1 As an exemplary embodiment of the utility model, a multi-degree-of-freedom flexible platform includes a base plate 1, a first adjustment plate 4, a second adjustment plate 6 and a support plate 8 arranged in sequence from bottom to top, and also includes a front-rear guide mechanism 2 and a left-right guide mechanism 3 arranged between the base plate 1 and the first adjustment plate 4, a deflection mechanism 5 arranged between the first adjustment plate 4 and the second adjustment plate 6, and a plurality of buffer mechanisms 7 arranged between the second adjustment plate 6 and the support plate 8.

[0034] The base plate 1 is used to connect with the lift to provide vertical translation of the supported object through the lift. The base plate 1 and the first adjustment plate 4 are in the horizontal plane when the platform is in use. The first adjustment plate 4 can move forward and backward and left and right in the horizontal plane under the action of the front and rear guide mechanism 2 and the left and right guide mechanism 3. The second adjustment plate 6 can rotate in the vertical plane under the action of the deflection mechanism 5. The support plate 8 is used to carry the supported object, that is, the aviation product being repaired, to drive the product to move in all directions, so as to achieve its multi-degree-of-freedom adjustment when the product is installed. The buffer mechanism 7 is used to buffer the heavy objects and realize the flexible docking of the product.

[0035] The base plate 1 can be a thin plate with a roughly rectangular shape, and cooperates with the lift to realize the vertical movement of the supported object. In addition, the universal wheels under the lift can realize the front and back left and right movement of the platform, that is, lateral translation, and roughly align the supported product on the platform with the installation position, that is, realize the lateral rough alignment of the supported object.

[0036] The front and rear guide mechanism 2 and the left and right guide mechanism 3 enable the first adjustment plate 4 to translate in two directions perpendicular to each other in the horizontal plane, thereby driving the deflection mechanism 5, the second adjustment plate 6, the buffer mechanism 7 and the support plate 8 to translate in the horizontal plane together, thereby realizing the horizontal movement of the supported object and realizing its lateral fine-tuning function to accurately align with the installation position to meet its high-precision positioning requirements. The lateral fine-tuning of the front and rear guide mechanism 2 and the left and right guide mechanism 3 can be adjusted according to the actual production requirements.

[0037] In some embodiments of the present invention, the front and rear guide mechanism 2 and the left and right guide mechanism 3 may adopt the same structure. Figure 2 As shown, the front-to-back guide mechanism 2 includes two first sliders 21 connected to the left and right ends of the first adjustment plate 4, and two first guide rails 22 extending in the front-to-back direction. The first slider 21 can slide along the corresponding first guide rail 22, especially the first slider 21 slides in the dovetail groove of the first guide rail 22. The left-to-right guide mechanism 3 includes two second sliders 31 connected to the first guide rail 22, and two second guide rails 32 extending in the left-to-right direction. The second guide rail 32 is fixed to the base plate 1, and the second slider 31 can slide along the corresponding second guide rail 32, especially the second guide rail 32 passes through the dovetail groove of the second slider 31. It should be pointed out that the form of the sliders and guide rails in the front-to-back guide mechanism 2 and the left-to-right guide mechanism 3 is not limited thereto. For example, the number of the first sliders 21 can be four, two at the left end and two at the right end, and the shape of the guide rail groove can also be arbitrarily selected. In addition, the front-to-back guide mechanism 2 and the left-to-right guide mechanism 3 can be connected in any way as long as the movement of the two can be achieved.

[0038] The shape and size of the first adjustment plate 4 can be similar to the base plate 1. In order to facilitate the movement control of the first adjustment plate 4 and the use of the platform in a scenario where there is no power supply at the airport, the platform can also include two guide control components for controlling the front and rear guide mechanism 2 and the left and right guide mechanism 3 respectively. The guide control component includes a screw mechanism and a handwheel. The guide control component is not shown in the figure and can be implemented by known mature technology. The two screw mechanisms each include a matching screw and a nut. The screw used for the front and rear guide mechanism 2 is parallel to the first guide rail 22 and can be connected to the frame connected to the first guide rail 22. The nut is connected to the first adjustment plate 4. The handwheel is connected to the screw to drive the screw to rotate. When the handwheel is manually rotated, the screw rotates and the nut translates forward and backward, thereby driving the first adjustment plate 4 and the first slider 21 to translate forward and backward. The screw for the left and right guide mechanism 3 is parallel to the second guide rail 32 and can be connected to the frame connected to the second guide rail 32. The nut can be connected to the first guide rail 22. The hand wheel is connected to the screw to drive the screw to rotate. When the hand wheel is manually rotated, the corresponding screw rotates, and the matching nut translates left and right, thereby driving the first guide rail 22 and the second slider 31 and the first slider 21 to translate left and right together, thereby making the first adjustment plate 4 translate left and right. In this way, the first adjustment plate 4 can translate forward, backward, left and right, thereby achieving the forward, backward, left and right adjustment of the supported product.

[0039] Combination Figure 1 and Figure 2 , an angle fine-adjustment plane capable of a certain deflection angle, i.e., a second adjustment plate 6, is provided at the upper part of the lateral fine-adjustment structure. The deflection angle can be adaptively designed and adjusted according to the actual production angle. The shape and size of the second adjustment plate 6 can also be similar to the base plate 1. The second adjustment plate 6 is hinged to one end of the first adjustment plate 4 and can rotate relative to the first adjustment plate 4 around a horizontal pivot axis, and the pivot axis preferably extends in the front-to-back direction. The hinged connection between the second adjustment plate 6 and the first adjustment plate 4 can be achieved by two mounting seats connected to the two and a rotating shaft passing through the mounting seats. The utility model has no specific restrictions on this. The hinged position between the second adjustment plate 6 and the first adjustment plate 4 can be one or more locations as needed.

[0040] The deflection mechanism 5 is disposed at the other end of the first adjustment plate 4 and can drive the second adjustment plate 6 to rotate relative to the first adjustment plate 4, thereby driving the second adjustment plate 6, the buffer mechanism 7 and the support plate 8 to rotate together, thereby achieving deflection of the supported object.

[0041] In the exemplary embodiment, the deflection mechanism 5 is implemented by a hydraulic cylinder. Optionally, the deflection mechanism 5 includes two hydraulic cylinders arranged along the pivot axis, the cylinder body 51 of the hydraulic cylinder is hinged to the first adjustment plate 4, and the piston rod 52 is hinged to the second adjustment plate 6, wherein the two piston rods 52 share a hinge axis. Considering the use of the platform in a scenario without power supply, a hand pump can be used to provide power to the hydraulic cylinder to achieve the deflection adjustment of the second adjustment plate 6 and the deflection adjustment of the supported product. Combined with the use of a screw mechanism and a hand wheel to achieve the translation adjustment of the first adjustment plate 4, the platform can be used in scenarios where there is no power supply at the airport and can be used flexibly with the aircraft in the airport.

[0042] Reference Figure 3 Each buffer mechanism 7 includes a guide cylinder 71, a buffer spring 72 and a pillar 73. The guide cylinder 71 is vertically connected to the support plate 8. The shape and size of the support plate 8 may also be similar to the base plate 1. The guide cylinder 71 may be an integral part of the support plate 8 protruding vertically downward from its lower surface. The pillar 73 is vertically connected to the second adjustment plate 6. The pillar 73 may optionally be an integral part of the second adjustment plate 6 protruding vertically upward from its upper surface. The buffer spring 72 is sleeved on the lower end of the pillar 73, and the upper end of the pillar 73 is coaxially inserted into the guide cylinder 71, so that: one end of the buffer spring 72 contacts the open end of the guide cylinder 71, and the other end contacts the second adjustment plate 6, and the guide cylinder 71 can slide along the pillar 73, so that the support plate 8 and the supported object are buffered under the action of the buffer spring 72, thereby realizing a flexible docking support method for the supported object, thereby protecting the supported object and its counterpart from damage during the assembly process, and improving work reliability and safety. .

[0043] In particular, four buffer mechanisms 7 may be provided, which are respectively arranged at four corners of the support plate 8. However, those skilled in the art will appreciate that the structure and number of the buffer mechanisms 7 are not limited thereto.

[0044] In a preferred embodiment of the utility model, the buffer mechanism 7 further includes a brake pin 74, which can pass through the guide cylinder 71 and the support 73 to prevent the relative sliding of the guide cylinder 71 and the support 73. With the design of the brake pin, the rigidity and flexibility of the platform can be switched as needed. When the brake pin is inserted, the platform is a rigid platform, which is conducive to product transportation; when the brake pin is pulled out, the platform is a flexible platform for the installation of the supported object.

[0045] The operation method of the multi-degree-of-freedom flexible platform of the utility model is as follows:

[0046] Step 1, connecting the base plate 1 of the flexible platform to the elevator, at which time the deflection mechanism 5 is in the lowest position, in which the base plate 1, the first adjustment plate 4, the second adjustment plate 6 and the support plate 8 are parallel to each other;

[0047] Step 2, supporting the supported product on the support plate 8;

[0048] Step 3, start the hydraulic structure of the elevator to move the elevator so that the flexible platform rises to a certain position and the product is roughly aligned with the installation position;

[0049] Step 4, fine-tune the front and rear guide mechanism 2 and the left and right guide mechanism 3 so that the product is aligned with the installation position in the horizontal direction;

[0050] Step 5, if the product needs to be offset by a certain angle, the deflection mechanism 5 is used to implement the deflection adjustment of the product, thereby achieving precise alignment of the product, and thus the product can be assembled at its installation position with high precision.

[0051] As described above, the multi-degree-of-freedom flexible platform of the utility model has a simple structure. The platform cooperates with the elevator to provide vertical movement of the supported object and rough lateral alignment with the installation position. The front and rear guide mechanisms and the left and right guide mechanisms can realize lateral fine-tuning of the supported object in the front and rear, left and right directions, and the deflection adjustment is realized by the deflection mechanism. Therefore, the front and rear, left and right and deflection fine-tuning of the supported object can be realized to meet its high-precision positioning requirements. In addition, a flexible docking support method is provided by the buffer mechanism, which can avoid the defect that the existing installation platform is a rigid platform when the supported object is installed, and can protect the supported object and its counterparts from damage during the assembly process, thereby improving work reliability and safety.

[0052] Finally, it should be noted that the features mentioned and / or shown in the above description of the exemplary embodiments of the utility model can be combined in the same or similar manner into one or more other embodiments, combined with the features in other embodiments or replace the corresponding features in other implementations. The technical solutions obtained by these combinations or replacements should also be deemed to be included in the protection scope of the utility model.
