Description

Technical Field

[0001] The invention belongs to the technical field of assembly manufacturing, and relates to an auxiliary support device and method that can adapt to a variety of complex features. Background Art

[0002] When assembling complex feature products manufactured by aerospace-related companies, it is usually necessary to fix and suspend the parts for assembly. Parts often have variable features, different heights, and large diameter differences. At present, the fixed support method for assembling such products is mostly designed for a certain assembly process, and the corresponding auxiliary assembly tooling is designed separately to achieve fixed support for the parts of complex feature products. The structure of this type of auxiliary tooling is often relatively simple and mostly welded one-piece. The main purpose is to achieve fixed support and auxiliary assembly of parts of complex feature products. After the next assembly process or the assembly of a new batch of products, if the tooling does not meet the assembly requirements, a new tooling is manufactured to adapt to the new product type or new assembly process. This tooling structure designed separately for a specific product or assembly process is simple. Although it can achieve the fixed support effect for the parts of complex feature products, its fixed support form is single and has poor extensibility. It often cannot meet the requirements for the fixed support or assembly links that need to be adjusted, and it cannot achieve fixed support for parts of different sizes. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an auxiliary support device and method that can adapt to a variety of complex features, reduce adjustment time, facilitate operations, improve work efficiency, and achieve a fixed support effect for products with different complex features.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

The radial adjustment component is installed in the horizontal direction of the tooling chassis, the axial adjustment component and the welding plate are installed in the vertical direction of the tooling chassis, and the tooling bracket is connected to the axial adjustment component.

[0006] The radial adjustment assembly includes a first hand wheel, a reducer, a first coupling, a bearing seat I, a first screw, a first slider, a first adapter seat, and a bearing seat II which are connected in sequence. The bearing seat I and the bearing seat II are fixed to the tooling chassis by screw connection. The first hand wheel is rotated to drive the first adapter seat to move, thereby realizing radial adjustment of the device.

[0007] The axial adjustment assembly includes a second hand wheel, a right-angle reducer, a second coupling, a first bearing seat, a second screw, a second slider, a second adapter seat, and a second bearing seat, which are connected in sequence. The first bearing seat and the second bearing seat are fixed to the welding plate by screws. The second hand wheel is rotated to drive the second adapter seat to move, thereby realizing the axial adjustment of the device.

[0008] The tooling bracket comprises a guide rail, a main slide rail, a clamping slide block, and connecting bolts. The main slide rail is connected to the guide rail via the connecting bolts, and the clamping slide block is connected to the main slide rail.

[0009] As a preferred embodiment, the guide rail is also connected with an auxiliary slide rail and an auxiliary slider. The auxiliary slide rail and the auxiliary slider are used to position some assembly workpieces with large deflection during product assembly, and multiple auxiliary slide rails and auxiliary sliders can be added, depending on the specific tooling conditions.

[0010] As a preferred embodiment, the radial adjustment components and the axial adjustment components are provided in three groups respectively and are evenly distributed on the tooling chassis.

[0011] Further preferably, the tooling chassis is in a clover-leaf shape, which reduces weight and also facilitates the operator's positioning.

[0012] Further preferably, the tooling chassis is provided with a scale matching the radial adjustment assembly, so as to facilitate the operator to adjust the first adapter on the radial adjustment assembly to a more precise position.

[0013] Further preferably, a pad or casters are provided at the bottom of the tooling chassis to facilitate movement of the device.

[0014] Further preferably, the guide rail is provided with a scale to facilitate precise adjustment of the positions of the main slide rail and the auxiliary slide rail.

[0015] Further preferably, the main slide rail is also connected to a support block. For a workpiece with an irregular support surface, in order to ensure the stability of its axial support on the main slide rail, a support block is provided on the main slide rail to achieve workpiece positioning.

[0016] The present invention also provides a method for using an auxiliary support device that can adapt to a variety of complex features, comprising the following steps:

[0017] S1. Place the auxiliary support device on the workbench and ensure that it is placed horizontally and without shaking.

[0018] S2. Obtain the approximate size of the assembly workpiece, adjust the main slide rail to the appropriate position, and fix it to the guide rail with connecting bolts.

[0020] S4. Place the assembled workpiece on the main slide rail and adjust the radial adjustment component as needed to tighten and fix it.

[0021] The present invention forms a fixed support device with strong expandability by using a radial adjustment component, an axial adjustment component and a tooling bracket, etc., which is used to achieve fixed support during the assembly of complex feature products in various processes and to quickly replace complex feature products of different types and sizes during assembly.

[0022] The present invention has the following advantages:
