Technical Field
[0001] The invention belongs to the technical field of thin shell structure processing, and in particular relates to an internal and external pressing and fixing processing tool for a thin shell structure. Background Art
[0002] A fixture is a device used to fix the object to be processed in the mechanical manufacturing process so that it occupies the correct position for construction or inspection. It is also called a fixture (qiǎjǜ). In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process can be called a fixture. The aerospace field involves various thin shell structures. The fragile thin shell structure often makes it difficult to install and process it on the machine tool, and it also requires a fixture to fix it.
[0003] The existing internal and external compression and fixing processing tooling for thin shell structures still has some defects, and most of them do not have protective functions. Since the thin shell structure is easily damaged and deformed when fixed, a large number of defective products often appear, which increases the production cost. For this reason, we propose a thin shell structure internal and external compression and fixing processing tooling. Summary of the invention
[0004] The object of the present invention is to provide a tooling for internal and external compression and fixing of a thin shell structure, so as to solve the problem that most of the above-mentioned background technologies do not have a protective function.

[0006] Preferably, a first sliding block is provided on the surface of the screw rod, the first sliding block is slidably connected to the screw rod, a second spring is provided at the bottom of the first sliding block, and the second spring is fixedly connected to the first sliding block.
[0007] Preferably, a fixing block is provided in the middle of the screw rod, the fixing block is fixedly connected to the screw rod, and a third spring is fixed to the bottom of the fixing block.
[0008] Preferably, a second sliding block is fixed to the bottom of the third spring, and the second sliding block is slidably connected to the screw rod.
[0009] Preferably, a fixing ring is sleeved on the bottom of the screw rod, the fixing ring and the screw rod are slidably connected, and a clamping block is provided on the inner wall of the fixing ring, and the clamping block and the fixing ring are fixedly connected.
[0010] Preferably, a slide groove is embedded in the surface of the screw rod, and a clamping groove is provided at one end of the slide groove.
[0011] Preferably, a mounting seat is provided at the bottom of the telescopic rod, the mounting seat is fixedly connected to the telescopic rod, and a mounting hole is embedded on the surface of the mounting seat.
[0012] Preferably, the surface of the pressure ring is embedded with strip-shaped holes, and there are four strip-shaped holes.
[0013] Preferably, a limit block is provided inside the telescopic rod, and four sets of screw rods and nuts are provided in total.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. The workpiece is fixed by the support block, the first anti-slip pad, the pressure ring, the second anti-slip pad, the telescopic rod, the first spring, the screw and the nut. At the same time, the workpiece can be buffered and better protected. When the pressure ring squeezes the workpiece, it will drive the telescopic rod to contract and compress the first spring to achieve a buffering effect on the workpiece, solving the problem that some defects of the existing internal and external clamping and fixing processing tooling for thin shell structures still exist, most of which do not have protective functions. Since the thin shell structure is easily damaged and deformed when fixed, a large number of defective products often appear, which increases the production cost.
[0016] 2. The first sliding block, the second spring and the fixed block provide convenience for the disassembly of the pressure ring. The pressure ring can be fixed by screwing the nut, and the first sliding block is pushed to slide on the surface of the screw rod, thereby compressing the second spring. When disassembling, loosen the nut, and the first sliding block lifts the pressure ring under the reaction force of the second spring to complete the disassembly.
[0017] 3. The second sliding block, the third spring, the fixed ring, the clamping block, the slide groove and the clamping groove provide convenience for fixing the device and the machine tool platform. The bottom of the screw is inserted into the mounting hole of the machine tool, and then the fixed ring is inserted from the bottom of the screw. At the same time, the clamping block slides inside the slide groove to compress the third spring. When the fixed ring moves to a suitable position, the fixed ring is rotated and the clamping block is clamped into the inside of the clamping groove to complete the fixation of the structure. The structure is simple and easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS
