Abstract
The invention belongs to nuclear fuel element component full-automatic processing technical fields, and in particular to a kind of processing method of operating head.Steps are as follows: cylindrical blank being placed on horizontal Machining centers, center hole machined is carried out；It places it on lathe, reaming, while turning is carried out to centre bore；It places it in vertical machining centre, carries out the processing of hexagonal structure, boss and keyway；It places it on horizontal Machining centers, carries out the processing with the mating surface of other structures.The present invention solves the problems such as chip breaking encountered in automating process is difficult, cutter life is low, machining accuracy is unstable, realizes the full-automatic processing of the operating head.
Description
Technical field
The invention belongs to nuclear fuel element component full-automatic processing technical fields, and in particular to a kind of processing side of operating head
Method.
Background technique
Component production is the front end of China's fast reactor industrial chain, is introduced technology in manufacturing process technology without external, entirely
Portion is independent research.The component is domestic first production, and structure and other assemblies difference are larger, and belongs to nuclear fuel element,
Raw material are that CN-1515 belongs to Domestic New proprietary material, are showed no in related fields and illustrate to report.The operating head center is logical
Hole is hexagonal structure outside tail portion, and there are boss, keyway etc. in middle section.
Summary of the invention
The purpose of the present invention is to provide a kind of processing method of operating head, what solution encountered in automation process
The problems such as chip breaking is difficult, cutter life is low, machining accuracy is unstable, realizes the full-automatic processing of the operating head.
In order to achieve the above objectives, the technical solution used in the present invention are as follows:
A kind of processing method of operating head, steps are as follows:
Cylindrical blank is placed on horizontal Machining centers, center hole machined is carried out；
It places it on lathe, reaming, while turning is carried out to centre bore；
It places it in vertical machining centre, carries out the processing of hexagonal structure, boss and keyway；
It places it on horizontal Machining centers, carries out the processing with the mating surface of other structures.
The center of clamping workpiece after blank, horizontal processing drilling, all transport process clamp zero after lathe process
Position on the lower side in part.
When lathe process, one end is clamped using general claw, and the top of other end tail stock is fixed, benefit
End face positioning is carried out with locating piece.
When vertical processing, head is fixed with the mode that collet chuck accommodates, and the top fixation in tail portion is held using workpiece head
Face positioning.
It is obtained by the present invention to have the beneficial effect that
The present invention can satisfy component assembling requirement, according to the design scheme of tooling, it is determined that the production of the tooling
Technique simultaneously completes its processing.The final tooling is adjusted in rod assembly assembling for cobalt, can complete the group of different length component
Dress, the geometric tolerance of component meets upper and lower end faces depth of parallelism requirement 0.15mm after assembling；Axis and bottom plate end face squareness
It is required that 0.2mm；The maximum shape deviation in length component direction is no more than ± 2.5mm.Exit orifice concentricity is less than in fabricated part
0.05mm, mating part verticality are less than 0.05mm.Product processing efficiency is greater than 2h/ part, and product qualification rate is greater than 90%.
Specific embodiment
The present invention is described in detail combined with specific embodiments below.
The process steps of operating head of the present invention are as follows:
Cylindrical blank is placed on horizontal Machining centers (lathe), center hole machined is carried out；
It places it on lathe, reaming, while turning is carried out to centre bore；
It places it on vertical machining centre (lathe), carries out the processing of hexagonal structure, boss and keyway；
It places it on horizontal Machining centers (lathe), carries out the processing with the mating surface of other structures.
After blank, sleeping plus drilling after the center of clamping workpiece, lathe process in all equal holding parts of transport process
Position on the lower side.
In order to complete the processing of the operating head lathe part, one end is clamped using general claw, other end lathe
The top of tailstock is fixed, using locating piece carry out end face positioning, with this come guarantee workpiece automation process in essence
Degree.
When vertical machining centre is processed, head is fixed with the mode that collet chuck accommodates, and the top fixation in tail portion utilizes workpiece head
Portion carries out end face positioning.
