Description

Aircraft part frock of polishing Technical Field The utility model relates to the technical field of aircraft part machining, in particular to an aircraft part polishing tool. Background In the field of aerospace manufacturing, plumbing aircraft parts such as hydraulic tubing, fuel lines, and the like are widely used for their specific fluid transfer functions. Such parts are usually made of light alloy, have the characteristics of thin wall and hollow, and have significant influence on connection tightness and fluid resistance due to the quality of the outer surface, so that precise polishing treatment is often required. At present, the universal fixture is difficult to effectively adapt to different pipe diameters, the clamping stability is insufficient, the part is easy to shift or scratch the surface in the polishing process, and the requirements of aviation parts on high-precision and high-efficiency processing are difficult to meet. The prior art faces significant challenges when processing such thin wall pipeline part and polishes, firstly part wall is thin and the size specification is various, traditional anchor clamps are difficult to avoid leading to part to collapse deformation because of local excessive pressure when providing sufficient clamping force, especially risk is higher when rotatory atress of polishing, secondly, in order to adapt to different pipe diameters, usually frequent change anchor clamps or carry out loaded down with trivial details adjustment, seriously influence efficiency, in addition in rotatory polishing process, if clamping force distributes inequality, very easily cause part vibration or eccentric rotation, not only reduce the quality of polishing, still probably damage the part, consequently, according to above-mentioned technical problem, here propose an aircraft part frock of polishing. Disclosure of utility model The utility model aims to provide an aircraft part polishing tool, which realizes radial adjustment and self-locking clamping by synchronously controlling all outer expansion plates through single motor driving, can rapidly adapt to and clamp pipeline parts with different sizes, can ensure uniform distribution of clamping force, and effectively prevents deformation of thin-wall pipeline parts caused by uneven local pressure in the polishing process. The utility model is realized by the following technical scheme: The utility model provides an aircraft part frock of polishing, includes the operation panel, the upside fixedly connected with installation cover of operation panel, the first motor of outside fixedly connected with of installation cover, one side fixedly connected with of first motor rotates the post, and rotates the post and rotate the inside of connecting in the installation cover, the end fixedly connected with fixed section of thick bamboo of rotation post, the outer mechanism that expands of multiunit equidistant arrangement and dislocation installation is installed to the inboard of fixed section of thick bamboo, the internally mounted of fixed section of thick bamboo has the adjustment positioning mechanism, the upside fixedly connected with electric putter of installation cover, electric putter's output shaft end fixedly connected with polishing dish, and polishing the dish is located directly over the fixed section of thick bamboo. Preferably, the fixed cylinder is a hollow structure with a square groove formed in the fixed cylinder.
