Description

Technical Field

[0001] This invention belongs to the field of advanced assembly and manufacturing technology in aerospace, specifically relating to a detachable multi-stage height-adjustable cylindrical section fixing support device and method. Background Technology

[0002] Aerospace-related companies often manufacture cylindrical components with diverse characteristics, varying heights, and large diameter differences. Currently, most companies design fixed support devices specifically for a particular type and height of product. These fixed support devices are often relatively simple in structure and are mostly welded integral parts. Their main purpose is to provide fixed support for the cylindrical section. After the tooling for a certain type of product is exhausted, new tooling is manufactured to adapt to the new product type.

[0003] Although this type of tooling, designed specifically for a particular product, is simple and can achieve the effect of fixing and supporting the cylinder section, its fixing and support method is singular and cannot be adjusted in height. It cannot provide a good fixing and support effect for some product surfaces that are uneven or have large manufacturing errors, or for surfaces that require material addition or subtraction. It can also easily affect the subsequent machining accuracy of the cylinder section and cause waste of resources. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a detachable multi-stage height-adjustable cylindrical section fixing support device and method. By using a screw jack, a manual height adjustment device, a double-nut height fine-tuning mechanism, and clamping fixtures, a fixing support device is formed. Two or more fixing support devices can be used to achieve fixing support for cylindrical sections of different diameters and types. The device is detachable and can be adapted to different types of products, such as fixing support for certain large irregularly shaped parts, by changing different clamping fixtures.

[0005] To achieve the above objectives, the present invention employs the following technical solutions:

[0006] A detachable multi-stage height-adjustable cylindrical section fixed support device includes an automatic lifting device that controls the automatic lifting and lowering of the entire fixed support device. A primary support device, a secondary height adjustment device, a tertiary height fine-tuning device, and a clamping fixture are sequentially fixedly installed above the automatic lifting device. The number of fixed support devices is two or more, and the fixed support devices are sequentially installed around the cylindrical section.

[0007] Preferably, the automatic lifting device includes an explosion-proof motor, which is connected to a reducer. The output end of the reducer is also connected to a screw jack, and the screw jack is controlled by the explosion-proof motor driving the reducer.

[0008] Preferably, the primary support device includes a support base plate, which is fixedly connected to the screw jack; a support square tube is also welded onto the support base plate.

[0009] Preferably, the secondary height adjustment device includes a lower support plate, an upper support plate, a first adjustable square tube, and a second adjustable square tube; the lower support plate is fixedly connected to the supporting square tube, and the lower support plate is welded to the first adjustable square tube; the upper support plate is welded to the second adjustable square tube; the first adjustable square tube and the second adjustable square tube are detachably connected.

[0010] Preferably, there are two first adjustable square tubes, each with six adjustable holes, and the hole spacing is 50mm; there are two second adjustable square tubes, each with six adjustable 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 threaded holes, 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 holes, and is connected to the support top plate through the double nuts and the through hole.

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

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

[0014] S1. Adjust the position of the fixed support device, remove the device clamping fixture and support top plate, and fix it to the outer edge of the cylindrical product;

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

[0016] S3. Connect the clamping fixture and the top support 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 cylinder section;

[0018] S5. Adjust the automatic lifting device to ensure that the end face of the cylinder section reaches the ideal processing position.

[0019] The present invention has the following advantages:

[0020] (1) The height adjustment device of the present invention, composed of the first adjustable square tube and the second adjustable square tube, can achieve a large range of tooling height adjustment without affecting the strength of the fixed support of the cylinder section; the double nut height adjustment mechanism can achieve fine adjustment of the small range of height fluctuations of the cylinder section caused by processing errors.

[0021] (2) The fixed support device of the present invention has a simple structure, is easy to assemble and disassemble, is easy to operate, improves work efficiency, and can be used in combination with multiple fixed support devices to save costs and reduce preparation time.
