Abstract
The invention belongs to the field of machining, and in particular, relates to a machining method of a multi-connected precision hole. The precision deep hole machining is the machining difficulty of multiple complex bracket type parts; in actual machining process, the disqualification of surface roughness due to overproof aperture caused by lug vibration or unsmooth discharge of chips in holes caused by large hole depths is easy to generate; and or qualified parts cannot be machined due to unqualified geometric tolerance caused by positioning deviation or shake of ultralong drill bits. The invention provides a method for effectively machining parts with multi-connected precision holes, guarantees the machining quality of part holes, and can effectively prevent the vibration of lugs in the machining process.
Description
Technical field
The invention belongs to field of machining, be specifically related to a kind of processing method connecting precision holes more, especially there is the part of many group monaural sheets or complicated auricle structure, and the aperture on auricle is than the part more than 14 times.
Background technology
Precision deep hole processing is the processing difficulties of many Pedestal class parts, this type of part have more many group monaural sheets or complicated auricle structure especially part has single group or two groups and above pore structure and aperture than the precision holes processing more than more than 14 times, internal surface of hole roughness Ra more than 1.6 μm, and there is Geometrical Tolerance Principle in two groups of holes and also has Geometrical Tolerance Principle respectively with other positions, this type of hole machined difficulty is very big, in actual process as easy as rolling off a log due to auricle vibration cause overproof of aperture or due to chip removal in hole depth causing hole not smooth, cause surface roughness defective, or cause greatly form and position tolerance defective because deviations or overlength drill bit rock, qualified part cannot be processed.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of effective processing to have the method connecting precision holes part more, ensures the crudy of hole in piece part; Effectively can avoid the vibration of part auricle in process simultaneously.
The present invention's processing method connecting precision holes more, comprise the following steps: on part, digital control processing goes out datum level and datum hole for connecting the locating and machining of precision holes more, drilling tool has reinforcement, holding device, hold down gag and auxiliary clamping device, and reinforcement is provided with stationary bushing;
Frock is fixed on workbench, then part put into frock and fix, first the plug with drill bit same specification is fixed on the main shaft of lathe, the hole heart of lining described in mobile main shaft centering, make plug can by described lining, now fix and lock lathe XY axle and upwards lift, change the outfit lengthening drill bit, and drill bit is slowly reduced to above part, Drilling operation is carried out to part;
After boring, cleaning inner bore of part, carries out Manual reaming, until element precision hole machined is complete.

Detailed description of the invention
Below by example, the present invention will be further described:
A kind of processing method connecting precision holes part of the present invention first processes the part of part except precision holes by adopting more, frock is adopted to coordinate the first hole in lengthening drill bit machining accuracy hole again, pre-allowance carries out follow-up fraising, finally adopts concentric reamer to ream to whole hole dimension, and ensures concentric requirement.Concrete steps are as follows:
Digital control processing goes out part datum level and or datum hole
Other parts except precision holes of the complete part of digital control processing also process the positioning datum elements such as part datum level, datum hole
Design frock clamping and locating element
Frock selectes the good frock flat board 1 of a flatness as positioning reference plane, and be designed with on flat board with part 10 locating hole with the use of baseline trough 2, adopt pin 3 to insert part locating hole in groove to position part, fix frock holding device 7, can by part position accurate positioning, finally tighten hold down gag 8 and auxiliary clamping device 9 just can carry out Drilling operation
Drilling operation
Frock is fixed on workbench, with the standard core rods centering positioning tool lining 6 hole heart of same diameter, fix and lock lathe XY axle, refill folder special-purpose lengthening drill bit, and drill bit is slowly drop to above part, start lengthening drill bit part being carried out to Drilling operation clamping processing needs, start processing parts, continuous apply oil is noted in process, attentional manipulation Part temperature, avoid temperature to rise too high, often process a segment distance and drill bit is exited part and carry out bore cleaning, until completion of processing.
Adopt and lengthen concentric reamer machining accuracy hole
After boring, cleaning inner bore of part, carry out Manual reaming processing, reamer lead segment must lengthen, and guarantees good location, and chamfering is carried out in guiding front end, and reduce cutter relieving, shank also will lengthen guarantees that part can smoothly by whole group of endoporus.
Reamer carries out sufficient lubrication and starts processing parts after burr of polishing, point multitool ream inner bore of part surplus, notes observing bore area quality, lubricate in time in process, avoids dry hinge.Until element precision hole machined is complete.
Claims (1)
1. connect a processing method for precision holes more, it is characterized in that, the method comprises the following steps:
