The utility model discloses main tapping axial and lateral rigidity and precision have improved, had sufficient feed with rise speed, the linearity of main shaft motion with prevent that torsion performance takes a turn for the better, sensitivity improves, has guaranteed the machining precision, has improved holistic quality of machining center and performance simultaneously, and then has improved work efficiency.
Description
Technical field
This utility model belongs to die-cast formation equipment technical field, particularly to a kind of Precision Machining center main spindle nose.
Background technology
The quality of main tapping directly affects the technic index of machining center: productivity ratio, geometric accuracy and surface roughness, therefore main tapping is had following requirement by machining center: have certain axially and laterally rigidity and precision, have enough feedings and rise speed, motion of main shaft rectilinearity and anti-twisting property is good, sensitivity want high, without creeping phenomenon, the ability possessing reasonably carrying electrode quality, if above-mentioned condition there being one do not reach requirement, quality and the performance of machining center will be affected, be substantially reduced the work efficiency of product.
The design of existing main-shaft head structure is unreasonable, axially and laterally rigidity and precision are relatively low will to cause it, the feeding and the rise speed that make part are on the low side, and simultaneously the rectilinearity of motion of main shaft and anti-twisting property are all relatively low, first have to solve the technical problem that and are: change the structure at the place that goes wrong.
Utility model content
For solving above-mentioned technical problem, the utility model proposes a kind of Precision Machining center main spindle nose, it reasonable in design, it is ensured that the quality of foundry goods and performance.
The technical solution of the utility model is achieved in that
A kind of Precision Machining center main spindle nose, including fuselage, described fuselage is L-type four prisms cylinder structure, on the top of fuselage vertical portion, the left and right sides on edge and rear side are provided with wing plate, it is provided with external reinforcing ribs on the downside of wing plate and between fuselage outer wall, on fuselage roof, the rear side on edge is additionally provided with a connection seat, connection seat top is provided with a lead screw hole, in fuselage vertical portion, it is provided with interior reinforcement and draws material hole, the fuselage endoseptum of interior reinforcement both sides is provided with flash hole, a spindle hole it is provided with in standard of fuselage portion, the fuselage of the spindle hole left and right sides is each provided with a form, the left and right sides in the fuselage knuckle portion on the upside of spindle hole is symmetrically arranged with two withdrawing arm round platforms.
Preferably, draw described in material hole be two draw material circular hole and one draw material square hole.
Preferably, described connection seat is gusseted reinforcing plate structure.
The beneficial effects of the utility model are: after changing spindle hole, withdrawing arm round platform and drawing material hole site and size, main tapping axially and laterally rigidity and precision improve, there are enough feedings and rise speed, the rectilinearity of motion of main shaft and anti-twisting property take a turn for the better, sensitivity improves, this relatively before had and be obviously improved, the optimization of main-shaft head structure ensure that the machining accuracy of fuselage, improve the overall quality of machining center and performance simultaneously, and then improve work efficiency.
