In addition, the unstable and inefficiency of traditional positioning and clamping mode clamping, easily causes part rejection, is not suitable for producing in enormous quantities.
Summary of the invention
For avoiding above-described manufacturing deficiency, the utility model provides a kind of frock improving the quick high duplication positioning precision of integral wheel, a self-made tooling installed by numerical control machining center workbench, and this frock carries out axis by the groove equal with impeller blade number and mandrel and angle is located.
For achieving the above object, the technical solution of the utility model is: a kind of frock improving the quick high duplication positioning precision of integral wheel, comprise tooling base, mandrel, tooling base intermediate tie connecting mandrel, described tooling base clamping face is arranged the locating slot being used for impeller blade angle location, the quantity of locating slot is equal with impeller blade number, arranges a circle anti-interference groove, make locating slot be divided into inner position groove and outside fix groove in the middle of tooling base clamping face.
The width of described locating slot is greater than width of blade 0.02 ~ 0.2mm, and the degree of depth is 0.5 ~ 20mm.The width of described anti-interference groove is 1/3 ~ 2/3 of positioning groove length, and depth dimensions is 1.2 ~ 2 times of clamping slot depth, and bottom arranges the rounding of R=0.5 ~ 10mm.Described inner position slot length is 1/3 ~ 2/3 of outside fix slot length, falls 45 ° ~ 60 ° oblique angles being of a size of 0.2 ~ 1mm on each limit of locating slot.Described tooling base center finish-milling has the datum hole of Ф 6 ~ Ф 20 centering, and fall 30 ° of oblique angles being of a size of 1 ~ 2mm in aperture; On the X-axis axis of described tooling base (5), finish-milling width 3 ~ 10mm, dark 3 ~ 12mm frock X are to centering groove, notch bevelling, and bottom land falls R=0.5 ~ 8mm fillet.
The beneficial effects of the utility model are:
Compare with traditional positioning and clamping mode, numerical control machining center installs a positioning and clamping frock, only need frock concentricity, flatness calibration centering, can start to carry out part processing, in process, do not need to carry out secondary centering to part, improve working (machining) efficiency; Frock positions part by groove and mandrel, blade contacts gapless with groove, improve the accuracy of manufacture and the uniformity of positive and negative two ends blade, blade halving precision and dynamic balance of impeller performance meet specification of technical file, greatly enhance productivity, improve quality of production stability and reliability.
