Abstract
The utility model discloses a biaxial support shot blasting device. The biaxial support impellor head comprises a shot blasting device shell, a shot charge pipe, a shot distributing wheel, a directional sleeve and a shot blasting blade, wherein the right end of the shot distributing wheel is connected with a driving mechanism by a drive shaft; the drive shaft is installed in the shot blasting device shell by a right bearing. The biaxial support shot blasting device is characterized in that the left end of the shot distributing wheel and the shot charge pipe are communicated by a hollow shaft; the hollow shaft is installed in the shot blasting device shell by a left bearing. The shot blasting device operates by being supported by the left and right bearings together, and is higher in rotation speed, intensifies the stability, improves the shot blasting quantity, improves the shot blasting efficiency, and blasts shots more uniformly compared with an existing single support shot blasting device.
Description
Technical field
The utility model relates to especially shot-blasting machine technical field of surface cleaning equipment, specifically a kind of two axial support impeller head.
Background technology
The removing surface of foundry goods is one of important procedure in foundry production.Cleaning comprises removes the scab of cast(ing) surface and the core of inner chamber, removes the burning skin of dead head, fash, burr and heat treatment formation etc.Nearly three expand to again the workpiece life-span is strengthened, improved to surface of the work during the last ten years, rust cleaning, the knockout of deoxidation leather goods and the foundry goods scopes such as core that fall.
Shot-blasting machine is most important general basic equipment in surface of the work cleaning plant equipment, is widely used in the Treatment of Metal Surface such as rust cleaning, polishing, sand removal of the industries such as boats and ships, automobile engineering, machine-building, and domestic and international market demand is huge.
Impeller head is the core component of shot-blasting machine, it is cleared up piece surface, is the impeller that utilizes high speed rotary, bullet is thrown to the piece surface of continuous rolling by impeller head, remove remaining sand mold and the oxide skin of piece surface, thereby reach the object of cleaning raising surface strength.Therefore the design of impeller head is played vital effect to the performance of shot blasting machine product.
Through to the now analysis and research of publication and existing enterprise operation equipment, find that processing exists certain limitation to one-sided bearings to high quality of products, shake greatlyr, ball blast uniformity is bad.In order to make impeller head rotating speed higher, shot-blasting quality improves, and ball blast efficiency increases, and ball blast is more even, in the urgent need to the novel impeller head structure of one.
Utility model content
The shortcoming existing in order to overcome above-mentioned prior art, the purpose of this utility model is to provide a kind of operation more two axial support impeller heads.
In order to address the above problem, the utility model by the following technical solutions: a kind of two axial support impeller heads, comprise impeller head housing, entering pills apparatus, shot wheel, orienting cover, ball blast blade; Described shot wheel right-hand member connects driving mechanism by power transmission shaft; Described power transmission shaft is arranged in impeller head housing by right bearing; It is characterized in that: between the left end of described shot wheel and entering pills apparatus, be communicated with by a hollow shaft; Described hollow shaft is arranged in impeller head housing by left bearing.
Further: on described inner wall of hollow shaft, to be provided with helical form conveying guide groove.
Further: described left bearing, right bearing are self-aligning ball bearing.
Further: the integrated high-strength wearable cast member of described shot wheel and described hollow shaft.
The beneficial effects of the utility model are: this kind of impeller head is to work under the common support of left and right two bearings, compare existing single support impeller head rotating speed higher, and stationarity strengthens, and ball blast amount improves, and ball blast efficiency increases, and ball blast is more even.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described further:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is shot wheel in the utility model embodiment, the integrated structural representation of hollow shaft;
In figure: 1 entering pills apparatus, 2 orienting covers, 3 ball blast blades, 4 shot wheels, 5 disks, 6 right bearings, 7 ball blast mouths, 8 left bearings, 9 power transmission shafts, 10 hollow shafts, 101 helical form conveying guide grooves.
Detailed description of the invention
As shown in Figure 1, this pair of axial support impeller head, comprises impeller head housing, entering pills apparatus 1, shot wheel 4, orienting cover 2, disk 5, ball blast blade 3; On impeller head housing, be provided with ball blast mouth 7, described shot wheel 4 right-hand members connect driving mechanism by power transmission shaft 9; Described power transmission shaft 9 is arranged in impeller head housing by right bearing 6, and said structure all belongs to the structure existing in prior art.
The special feature of this pair of axial support impeller head is: between the left end of its shot wheel 4 and entering pills apparatus 1, be communicated with by a hollow shaft 10; Described hollow shaft 10 is arranged in impeller head housing by left bearing 8.
Left bearing 8, right bearing 6 form dual-gripper to shot wheel, hollow shaft, power transmission shaft, i.e. dual-gripper impeller head, the stationarity while operation to increase impeller head.
The improvement that the present embodiment is further taked: be provided with helical form conveying guide groove 101 on described hollow shaft 10 inwalls.Ball material in hollow shaft is dredged, prevented from stopping up, also further improve the uniformity of ball blast.
The improvement that the present embodiment is further taked: described left bearing 8, right bearing 6 are self-aligning ball bearing.For choosing of bearing, adopt self-aligning ball bearing.It can bear larger radial load, also can bear certain axial load simultaneously.Such bearing outer ring ball track is spheric, thus there is aligning performance, when the stressed bending of axle or inclination and while making inner ring center line and outer ring center line relative tilt be no more than 1 °～2.5 °, bearing endure.
The improvement that the present embodiment is further taked: described shot wheel 4 and the integrated high-strength wearable cast member of described hollow shaft 10, as shown in Figure 2; So that opposing and impact and the wearing and tearing of bearing ball material.
This impeller head course of work as shown in Figure 1, bullet is entered after shot wheel 4 through helical guide groove 101 guiding of hollow shaft 10 by entering pills apparatus 1, due to shot wheel 4 steady High Rotation Speed under the supporting role of duplex bearing, after bullet is accelerated by shot wheel 4 from orienting cover 2 windows fly out accepted by ball blast blade 3 and further accelerated the impeller head that flies out, surface of the work is carried out to efficient shock and process, and then obtain having the part of excellent surface properties.
The realizability of hollow shaft is larger, and hollow shaft only need to be born less shearing, because the hollow shaft of left end is equivalent to not load of idle running, just plays the effect of the unstable vibrations of a stable shot wheel High Rotation Speed.
