Abstract
The invention discloses a top plate assembling method of a lower chamber shot blasting machine. The method comprises the following steps of firstly, forming one top protecting plate fixing screw hole respectively on both side surfaces of a shot blasting machine shield; secondly, when matching a shot blasting machine top protecting plate with shot blasting machine end protecting plates and shot blasting machine side protecting plates, screwing fixing screws in through the fixing screw holes to press the shot blasting machine top protecting plate; thirdly, covering a shot blasting machine top cover plate, and fixing the shot blasting machine top cover plate through protecting plate pressing screws. The top plate assembling method of the lower chamber shot blasting machine solves the problem of mounting the top protecting plate during equipment maintenance, effectively protects sealing performance of a shot blasting machine and prolongs the service life of the shot blasting machine.
Description
Technical field
The present invention relates to the top board assembly and disassembly methods of a kind of lower storehouse impeller head.
Background technology
Shot-blasting machine (shot blasting machine), the impact cleaning device of the High-velocity Projectiles utilizing impeller head to dish out cleaning or strengthening cast(ing) surface.Ball blast function carries out knockout decoring and cleaning to foundry goods simultaneously.
First shot-blast apparatus is applied to foundry industry cast steel, the surperficial scab of ironcasting and the removing of oxide skin.Nearly all steel-casting, grey foundry goods, malleable iron component, G. Iron Castings etc. all will carry out Shot Blasting.This is not only to remove cast(ing) surface oxide skin and scab, also be indispensable preparatory process before casting quality checks simultaneously, such as large-scale gas-turbine casing must carry out strict throwing blast cleaning before carrying out nondestructive inspection, to ensure the reliability of result of detection.In general castings production, throwing blast cleaning is find the requisite process means of casting surface defect as subcutaneous blowhole, cinder hole and scab, cold shut, peeling etc.Non-ferrous casting, as the removing surface of aluminium alloy, copper alloy etc., except descaling, finding the blemish of foundry goods, main object throws shot-peening to remove the burr of die casting and to obtain the surface quality with decoration meaning, obtains resultant effect.
Lower storehouse impeller head, due to the state of its oblique inverted, dropping to exist due to top board deadweight when when regular maintenance, top board refills back after taking apart coordinates situation not in place, causes the blow-by of guard shield inner casing and leaks ball, as easy as rolling off a log damage impeller head.In practical operation, also not good way has fixed top board and to have beared down on one lid again.
Summary of the invention
The object of this part is some aspects of general introduction embodiments of the invention and briefly introduces some preferred embodiments.May do in the specification digest and denomination of invention of this part and the application a little simplify or omit with avoid making this part, specification digest and denomination of invention object fuzzy, and this simplification or omit and can not be used for limiting the scope of the invention.
In view of Problems existing in the top board assembly and disassembly methods of above-mentioned and/or existing lower storehouse impeller head, propose the present invention.
Therefore, an object of the present invention is to provide the top board assembly and disassembly methods of a kind of lower storehouse impeller head, it can overcome lower storehouse impeller head top board and take maintenance apart and cannot accurately install, and top board assembling is not in place, leaks the problem that sand damages impeller head.
For solving the problems of the technologies described above, the invention provides following technical scheme: the top board assembly and disassembly methods of a kind of lower storehouse impeller head, it comprises the steps, step one, respectively opens a top backplate technique for fixing screw hole in the two sides of impeller head guard shield; Step 2, when impeller head top backplate is coupled to impeller head endshield and side guard plate, is twisted fixed screw by technique for fixing screw hole and pushes down impeller head top backplate; Step 3, covers impeller head lamina tecti, and fixes with backplate housing pin.
As a kind of preferred version of the top board assembly and disassembly methods of lower storehouse of the present invention impeller head, wherein: described aperture is between M8 ~ M12.
Push up the installation question of backplate when the invention solves plant maintenance, available protecting impeller head seals, and increases the service life.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.Wherein:
Fig. 1 is the main body schematic diagram of lower storehouse of the present invention impeller head;
Fig. 2 is the A-A generalized section of lower storehouse of the present invention impeller head;
Fig. 3 installs fixing schematic diagram for pushing up backplate described in one embodiment of the invention.
Detailed description of the invention
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, are described in detail the specific embodiment of the present invention below in conjunction with specific embodiment.
Set forth a lot of detail in the following description so that fully understand the present invention, but the present invention can also adopt other to be different from alternate manner described here to implement, those skilled in the art can when without prejudice to doing similar popularization when intension of the present invention, therefore the present invention is by the restriction of following public specific embodiment.
Secondly, alleged herein " embodiment " or " embodiment " refers to special characteristic, structure or the characteristic that can be contained at least one implementation of the present invention.Different local in this manual " in one embodiment " occurred not all refers to same embodiment, neither be independent or optionally mutually exclusive with other embodiments embodiment.
As shown in Figures 1 to 3, in this embodiment, under the present invention, storehouse impeller head mainly comprises: impeller head guard shield 1, impeller head lamina tecti 2, impeller head top backplate 3, impeller head endshield and side guard plate 4, backplate housing pin 5, top backplate technique for fixing screw hole 6 and fixed screw 7.
First, respectively open a top backplate technique for fixing screw hole 6 in the two sides of impeller head guard shield, aperture is selected between M8 ~ M12.
Because lower storehouse impeller head entirety is in oblique inverted state, in regular maintenance, can drop because of deadweight when impeller head top backplate 3 is installed, cause effectively to coordinate with impeller head endshield and side guard plate 4, cause leaking ball.
A top backplate technique for fixing screw hole 6 is respectively opened by the two sides at impeller head guard shield 1, when impeller head top backplate 3 is coupled to impeller head endshield and side guard plate 4, by technique for fixing screw hole 6 fixed screw 7 twisted and push down impeller head top backplate 3, and then impeller head lamina tecti 2 is covered, and fix with backplate housing pin 5.By this technical scheme, push up the installation question of backplate when the invention solves plant maintenance, available protecting impeller head seals, and increases the service life.
It should be noted that, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
