Abstract
The invention discloses a superlong and easy-deformed processing clamping device for propellant loading and overcomes the defects of the prior art. The superlong and easy-deformed processing clamping device for the propellant loading is composed of two parts, namely a standard chuck clamping jaw and an embracing barrel. A propellant grain is embraced by virtue of the embracing barrel, loading time is shortened, clamping compressive deformation of the propellant grain is reduced, working efficiency and propellant grain processing accuracy are improved, both time and labour are saved, and safety in a propellant grain processing process is also greatly improved. The superlong and easy-deformed processing clamping device for the propellant loading is easy to operate and applicable to turning of multiple propellant grains.
Description
Technical field
The present invention relates to a kind of overlength and yielding propellant loading clamping device, belong to solid rocket propellant manufacture field.
Background technology
Long-range precision strike is the development trend of missile weapon system, and this just requires motor charge high-energy in armament systems to addThing is more and more, and size is more and more longer. This type of powder charge at present adopts cast molding, rear machining and shaping mode mostly. Add at powder columnIn carefully and neatly done shape, powder column grips particularly important, is related to machining accuracy and the handling safety of powder column size. Overlength and easy at presentWhat distortion propellant charge machining and shaping adopted is traditional approach, i.e. front end lathe three-claw clamping, and rear end is top to be held. This folderMainly there is following problem in the method for holding: (1) complicated operation, speed is slow, efficiency is low, can not meet the demand of turning in enormous quantities. (2)Powder column is fixing not firm, in Tutrning Process, powder column slippage easily occurs and even drop and wait danger. (3) powder column and latheAxiality is poor, and machining accuracy can not be guaranteed.
Summary of the invention
The object of the invention is to overcome prior art deficiency, design the processing clamping device of a kind of overlength and yielding propellant loading,Improve powder column turning working (machining) efficiency by this device, the more important thing is and improved security and the powder column turning processing in turning processPrecision quality.
Processing clamping device provided by the invention, is made up of standard chuck jaws and an armful cylinder. Described standard chuck jaws is common threeThe chuck jaws that pawl lathe is general; Described armful of cylinder length L determine according to the length of powder column, to ensure that powder column clasps firmly, internal diameterR1 determines according to the external diameter of powder column, to ensure powder column and to embrace cylinder and clasp comprehensively, reduces the clamping deformation of powder column, ensures machining accuracy,Thickness N determines according to powder column weight, to ensure safety, embraces cylinder and is connected with standard chuck jaws by welding manner, by protectingCard is embraced cylinder and the perpendicularity of claw to guarantee lathe chuck and an axiality of embracing tin. One group of clamping device holding card of the present invention is by three listsOnly holding card composition, installs to after lathe for machining by chuck jaws, and an armful cylinder for holding card forms cylindric, treats the powder column of turning processingPut into clamping device from cylinder one end, after device to be held is fastening, just can carry out turning processing.
Advantage of the present invention: (1) is simple to operate, the upper and lower powder column of lathe is fast, and efficiency is high; (2) powder column clamping is firm, and security is largeLarge raising; (3) axiality is high, has improved the machining accuracy quality of powder column.
Brief description of the drawings
Fig. 1 is the single holding card side view of the present invention;
Fig. 2 is the single holding card top view of the present invention;
Fig. 3 is one group of holding card top view of the present invention;
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail.
With reference to Fig. 1-3, according to certain model size of powder charge weight, determine and embrace cylinder 2 length L=357mm, internal diameter R1=80mm is thickDegree N=6mm. Embrace cylinder and 2 be connected with standard chuck jaws 1 by welding manner, embrace tins 2 vertical with claw 1 by guaranteeDegree is to guarantee lathe chuck and the axiality of embracing cylinder 2. One group of clamping device holding card of the present invention is made up of three independent holding cards, logicalCross chuck jaws 1 and install to after lathe for machining chuck, holding card embrace cylinder 2 form cylindric, then by the powder column for the treatment of turning processing fromClamping device is put in cylinder one end, after device to be held is fastening, just can carry out turning process operation.
Carry out the turning processing of powder column with this clamping device, the particularly turning of powder column in enormous quantities processing, the upper and lower powder column of lathe is fast,, operationSimply, efficiency is high; Embrace cylinder 2 and powder column comprehensive engagement, it is firm to clamp, and powder column deformation is little, and security also improves greatly; Powder columnHigh with the axiality of lathe chuck, improve the machining accuracy quality of powder column.
