[0001] The present invention belongs to the technical field of advanced assembly and manufacturing of aerospace, and in particular relates to a detachable multi-stage height-adjustable barrel section fixing support device and method. Background Art

[0002] The barrel section parts manufactured by aerospace related enterprises often have varied characteristics, different heights, and large differences in diameters. The current barrel section fixed support methods of enterprises are mostly to design a fixed support device specifically for a product of a certain fixed type and fixed height. The structure of the fixed support device is often relatively simple and is mostly a welded one-piece part. The main purpose is to achieve fixed support for the barrel section. After the tooling for a certain type of product is used up, new tooling is manufactured to adapt to the new product type.

[0003] Although this tooling designed specifically for a specific product is simple and can achieve the effect of fixed support for the barrel section, its fixed support form is single and cannot be adjusted in height. It cannot provide a good fixed support effect for some products with uneven surfaces or surfaces with large manufacturing errors, or surfaces that require material addition or subtraction, and it is easy to affect the subsequent processing accuracy of the barrel section and cause a waste of resources. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a detachable multi-stage height-adjustable barrel segment fixed support device and method. A fixed support device is formed by using a spiral elevator, a manual height adjustment device, a double-nut height fine-tuning mechanism, a clamping tool, etc. Two or more fixed support devices are used to achieve fixed support for barrel segments of different diameters and types. The device is detachable and can adapt to different types of products by replacing different clamping tools, such as fixed support for certain large special-shaped parts.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0010] Preferably, there are two first adjustable distance square tubes, each with six adjustable distance holes, and the hole spacing is 50mm; there are two second adjustable distance square tubes, each with six adjustable distance holes, and the hole spacing is 50mm; the height of the secondary height adjustment device is adjusted by fixing bolts.

[0011] Preferably, the three-stage height fine-tuning device includes a double-nut height adjustment mechanism and a support top plate; the support upper plate is provided with a threaded hole, and the support top plate is a through hole; the double-nut height adjustment mechanism is connected to the support upper plate through the threaded hole, and is connected to the support top plate through the double nut and the through hole.

[0012] Preferably, the clamping fixture comprises a workpiece clamping block, and the workpiece clamping block is fixedly connected to the supporting top plate by bolts and nuts.

[0013] A method for using a detachable multi-stage height-adjustable barrel section fixing support device comprises the following steps:

[0014] S1. Adjust the position of the fixed support device, remove the device pressing tooling and the support top plate, and fix them to the outer edge of the barrel segment product;

[0015] S2. Adjust the positions of the first adjustable square tube and the second adjustable square tube so that the adjustable height varies within a small range, and then fix their positions with bolts and nuts;

[0016] S3, connect the clamping fixture and the supporting top plate to the double-nut height adjustment mechanism, adjust them to the appropriate position and then tighten the nuts to fix the entire fixed support device;

[0017] S4. Repeat the above operation for other fixed support devices to complete the full fixation of the barrel section;

[0018] S5. Adjust the automatic lifting device so that the end face of the barrel section reaches the ideal processing position.
