Abstract
A kind of nozzle, comprises a channel part passed through for sandblasting, a rifle head, and first the high speed sandblasting exported via channel part is injected on the outer surface of rifle head, then acts on the shaft tube inner wall of workpiece after the outer acting surface refraction of rifle head.First high-pressure sand blast is injected on outer spigot surface by this guiding nozzle, then is refracted on shaft tube inner wall to be processed by outer spigot surface, thus completes the cleaning of oxide skin on inwall.During installation, by the sleeve weld of this nozzle on lance head.This nozzle long service life, oxide skin cleaning effect are good, and this processing method processing step is simple, easy to implement.
Description
Technical field
The utility model relates to ball blast technical field, especially relates to a kind of blast nozzle being applicable to long deep hole shaft tube inner wall.
Background technology
At present, long deep hole class shaft tube inner wall oxide layer cleaning can adopt the method for blasting treatment, and grit-blasting treatment process, compared to pickling processes method, has the advantage that the feature of environmental protection is good, compared to endoporus Milling Process facture, there is the advantage that working (machining) efficiency is high, precision is high, cost is low.In prior art, the nozzle completing the sand-blasting machine of sandblasting processing is through type nozzle, if application number is a kind of automatic sand-blasting machine disclosed in the utility model patent of 201020249289.8, this machine comprises sandpipe, cylinder and pressurizer, sandpipe is arranged on sandpipe supporting seat, sandpipe one end is connected with the piston stretched in cylinder, and the sandpipe other end is equipped with abrator head, and sandpipe supporting seat and cylinder are contained on fixed support.During work, sand-blasting machine and workpiece rotating mechanism are combined, by rotating mechanism for workpiece provides comprehensive blasting treatment, bending abrator head automatically extend into inner hole of workpiece and carries out the clean processing of deep hole.This machine ensure that machining accuracy, avoids the pollution on workpiece inner wall surface, and the sand grains in sandpipe can be changed as required, to meet the requirement of different surfaces polishing.But because the sandblasting of high pressure is directly sprayed from abrator head, it is large that pressure is born at abrator head place, and abrator head damaged phenomenon is serious, need frequent replacing abrator head accessory, therefore service life of equipment is short, and maintenance cost is high.
Summary of the invention
The purpose of this utility model is to provide a kind of guiding nozzle be applicable on sand-blasting machine, the use of guiding nozzle both ensure that working (machining) efficiency and required precision, also extend nozzle service life, reduce processing cost, the technical scheme adopted is: a kind of nozzle, comprise a channel part passed through for sandblasting, a rifle head, first the high speed sandblasting exported via channel part is injected on the outer surface of rifle head, then acts on the shaft tube inner wall of workpiece after the outer acting surface refraction of rifle head.
Technical characteristic of the present utility model also has: described channel part comprises sleeve, the back-up ring be connected with sleeve threaded one end.
Technical characteristic of the present utility model also has: described rifle head comprises guiding rifle head, the stud be fixed together with guiding rifle head, stud is connected with shunt cylinder by screw thread, and shunt cylinder has also been threaded gear cap, and the outer acting surface of described rifle head is the outer surface of guiding rifle head.
Technical characteristic of the present utility model also has: the outer surface of described guiding rifle head is taper seat.
Technical characteristic of the present utility model also has: the bus of described taper seat and level are 20 degree-70 to angle and spend.
Technical characteristic of the present utility model also has: the circular passage between back-up ring and shunt cylinder is just to the outer surface of guiding rifle head.
The beneficial effects of the utility model are: first high-pressure sand blast is injected on outer spigot surface by this guiding nozzle, then are refracted on shaft tube inner wall to be processed by outer spigot surface, thus complete the cleaning of oxide skin on inwall.During installation, by the sleeve weld of this nozzle on lance head.This nozzle long service life, oxide skin cleaning effect are good, and this processing method processing step is simple, easy to implement.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.The utility model discloses a kind of guiding nozzle, so-called guiding nozzle refers to that high-pressure sand blast is not directly be sprayed onto from nozzle in workpiece inner wall, but be first sprayed onto on a guide surface, the outer surface of the rifle head that such as leads, then be ejected on surface of the work after outer surface reflection.This nozzle comprises a channel part passed through for sandblasting, a rifle head, first the high speed sandblasting exported via channel part is injected on the outer surface of rifle head, act on the shaft tube inner wall of workpiece after the outer acting surface refraction of rifle head again, thus complete the removal of workpiece spindle inside pipe wall oxide layer.
Channel part comprises sleeve 5, the back-up ring 3 be connected with sleeve 5 threaded one end.Rifle head comprises guiding rifle head 1, the stud 2 be fixed together with guiding rifle head 1, and stud 2 is connected with shunt cylinder 4 by screw thread, and shunt cylinder 4 has also been threaded gear cap 6, and the outer acting surface of rifle head noted earlier is the outer surface of guiding rifle head 1.
The outer surface of rifle head 1 of leading in the present embodiment is taper seat.The bus of the taper seat of guiding rifle head 1 and level are 20 degree-70 to angle and spend.Circular passage between back-up ring 3 and shunt cylinder 4 is just to the outer surface of the rifle head 1 that leads.
Corresponding, the invention also discloses a kind of blasting method, the method adopts above-mentioned guiding nozzle, and the method comprises the following steps:
1) nozzle is connected with the spray gun of sand-blasting machine;
2) start sand-blasting machine, spray gun is extend in workpiece spindle inward hole, in sand-blasting machine, pass sleeve 5 through the high-pressure sand blast of pressurization via behind sleeve 5 endoporus of channel part, circular passage between back-up ring 3 and shunt cylinder 4;
3) high-pressure sand blast passing sleeve 5 is injected on the outer surface of guiding rifle head 1, act in workpiece inner wall after outer surface refraction again, oxide layer in workpiece inner wall is removed under high-pressure sand blast effect, thus completes and process the sandblasting of long deep hole shaft tube inner wall.
