The purpose of the present invention is achieved through the following technical solutions: a kind of tooling of multistation processing fuel nozzle shell, It includes mounting plate, turn left on the top surface of the mounting plate and from the right side be sequentially arranged the first machining position, the second machining position and Third machining position, the first machining position, the second machining position and third machining position include the through slot being opened on mounting plate, are located at and lead to Two pin holes of slot left and right sides, two threaded holes positioned at through slot left and right sides, two pin holes are positioned with two on blank respectively Hole is corresponding, and two threaded holes are corresponding with two through-holes on blank respectively, two threaded holes of first machining position it Between line be horizontal line, the line between two threaded holes of the second machining position is tilted to the right upwards, the two of third machining position Line between a threaded hole is tilted to the left upwards.
Spacing between two neighboring through slot is equal.
The method of multi-station tooling processing fuel nozzle, it the following steps are included:
S1, the mounting plate of the tooling is fixed on the workbench of numerical control machining center；
The tooling of S2, the first blank: first taking the first blank, and two location holes of the first blank are respectively corresponded to the first processing Two pin holes of position, and insert pin between pin hole and location hole, at this time the two of the first blank through-hole respectively with two spiral shells Pit is corresponding, and screw is then passed through through-hole and is threadedly coupled with threaded hole, so that the first blank tooling be fixed；
S3, two deep holes and shape are processed on the connector pedestal of the first blank by numerical control machining center；After processing, work People is successively added in the first blank tooling to the second machining position on the Ministry of worker A to be added of the first blank by numerical control machining center Work goes out nipple A and fuel feed hole, while continuing second blank of tooling in original first machining position；After processing, worker will In first blank tooling to third machining position, successively processed on Ministry of worker B to be added by numerical control machining center nipple B and Fuel feed hole；
After S4, step S3, finished fuel nozzle body can be obtained, subsequent worker unloads the first blank from 3rd station Under, such circulate operation, can machining blanks process velocity.
The invention has the following advantages that structure of the invention is compact, easy to operate, the reduction clamping take-down time, improves processing Efficiency.

Specific embodiment
The present invention will be further described with reference to the accompanying drawing, and protection scope of the present invention is not limited to as described below:
As shown in Fig. 5 ~ 7, a kind of tooling of multistation processing fuel nozzle shell, it includes mounting plate 11, the mounting plate 11 Top surface on and turn left from the right side and be sequentially arranged the first machining position, the second machining position and third machining position, the first machining position, Two machining positions and third machining position include the through slot 12 being opened on mounting plate 11, two pin holes positioned at 12 left and right sides of through slot 13, positioned at two threaded holes 14 of 12 left and right sides of through slot, two pin holes 13 are corresponding with two location holes 6 on blank respectively, Two threaded holes 14 are corresponding with two through-holes 7 on blank respectively, between two threaded holes 14 of first machining position Line is horizontal line, and the line between two threaded holes 14 of the second machining position is tilted to the right upwards, two of third machining position Line between threaded hole 14 is tilted to the left upwards.
Spacing between two neighboring through slot 12 is equal.
The method of multi-station tooling processing fuel nozzle, it the following steps are included:
S1, the mounting plate 11 of the tooling is fixed on the workbench of numerical control machining center；
The tooling of S2, the first blank 15: first taking the first blank 15, and two location holes 6 of the first blank 15 are respectively corresponded Two pin holes 13 of the first machining position, and pin is inserted between pin hole 13 and location hole 6, two of the first blank 15 are logical at this time Hole 7 is corresponding with two threaded holes 14 respectively, and screw 18 is then passed through through-hole 7 and is threadedly coupled with threaded hole 14, thus will First blank, 15 tooling is fixed；
S3, two deep holes and shape are processed on the connector pedestal 1 of the first blank 15 by numerical control machining center；Processing Afterwards, worker is by the first blank 15 tooling to the second machining position, by numerical control machining center the first blank 15 the Ministry of worker to be added Nipple A2 and fuel feed hole 8 are successively processed on A9, while continuing second blank of tooling in original first machining position；Add After work, worker is successively added in the first blank 15 tooling to third machining position on Ministry of worker B10 to be added by numerical control machining center Work goes out nipple B3 and fuel feed hole 8；
After S4, step S3, finished fuel nozzle body can be obtained, subsequent worker unloads the first blank from 3rd station Under, such circulate operation, can machining blanks process velocity.
Therefore processing method processing finished product fuel nozzle need to only carry out tooling three times, and complete to add by feed three times Work, and traditional processing method needs multiple tooling and completes the process, therefore when the processing method considerably reduces clamping disassembly Between, shorten the process-cycle, improve processing efficiency.
