Part as shown in Figure 1 is aero-engine band heat screen bushing, and there are some problems for the processing of such part: in vehicle Processing dimension 1. when (H in corresponding diagram 1), existing method be three-jaw centering chuck can only slight clamping, then continuous adjustment correction, It since design of part is unfavorable for the clamping of Vehicle Processing, causes to be easy to weigh piece surface wounded, part type face is caused to deform, process fashionable dress It is very difficult to clamp position.
Summary of the invention
Device and clamping method the object of the present invention is to provide a kind of aero-engine with heat screen bushing class Vehicle Processing, It compresses clamping device with self-control centering to be fixed on the positioning, clamped one time centering guarantees part repeated clamping fast and stable, reduces Labor intensity improves processing efficiency, guarantees processing quality.
Clamping method principle of the aero-engine of the present invention with heat screen bushing class is: first according to actual parts type face A set of clamping and positioning device is manufactured with size design;Secondly, in clamping, using self-control clamping device main shaft elder generation clamping in lathe On, centering simultaneously fixes, and guarantees that clamping repeatability, Set and Positioning stability are good;Finally, part is used copper on main shaft The positioning of position guide cone and compressing component are formulated, and is connected through a screw thread using nut with tight part.
Include the following steps:
(1) a set of positioning and clamping device is designed according to actual parts type face and specific size;
(2) on lathe, centering simultaneously fixes self-control clamping device main shaft elder generation clamping, guarantees clamping repeatability, clamping Position stability is good;
(3) part is on main shaft, with the positioning of copper positioning and guiding cone and compressing component;
(4) it is tight to be threadedly coupled band.
Technical scheme is as follows:
A kind of device of the aero-engine with heat screen bushing class Vehicle Processing, including main shaft, locating tensioning guide cone, washer And hex-head nut;
The main shaft is multi-diameter shaft, including is also wrapped with matched first shaft part in sheet metal part type face and the second shaft part respectively Include the screwed third shaft part in surface;
Locating tensioning guide cone center is provided with through-hole, and outer surface is the conical surface, and the aperture of the through-hole is greater than third axis Section outer diameter;
The inner hole of the hex-head nut is threadedly coupled with third shaft part, and hex-head nut and locating tensioning guide cone it Between be provided with washer.
Preferably, the hex-head nut is copper nut.
A kind of clamping method using above-mentioned aero-engine with heat screen bushing class lathe machining device, including following step It is rapid:
Step 1: when Vehicle Processing, clamping device main shaft big end three-jaw centering clamping chuck is first positioned into centering and fixation It is good;
Step 2: sheet metal part is packed into main shaft, sheet metal part surfaceIt is bonded with the second shaft part surface of main shaft;
Step 3: locating tensioning guide cone is inserted into main shaft orientation and compresses sheet metal part, so that sheet metal part surface It is bonded with first axle section surface, locating tensioning guiding poppet surface;
Step 4: it is packed into washer, and is tightened sheet metal part and clamping device by screw thread with hex-head nut.
Be compared with the traditional method the invention has the advantages that
1, shorten the process-cycle.Clamping device structure is simple, processing and loading clamp accurate positioning fast and stable, and convenient disassembly is fast Victory, processing clamping period are foreshortened to present 1min by original 20min;
2, processing quality is improved.It is compressed using copper taper guide-localization, part process is avoided the feelings such as to weigh, deform wounded Condition occurs, and reduces part and reprocesses, part passing rate of processing is increased to 100%.
Clamping processing method and clamping device of the invention at present uses at the scene, has reached goal of the invention requirement.
Detailed description of the invention
