Background
The impeller refers to a disk provided with moving blades, is a component of an impulse turbine rotor, and can also be a general name of the disk and the rotating blades arranged on the disk. The impellers can be classified according to shape and opening and closing conditions.
The impeller production often adopts sand casting mode preparation, nevertheless need polish to the surface of impeller after the impeller production, need a frock to polishing of impeller, come to fix the impeller, adopt the upper and lower both ends of centre gripping impeller among the prior art, however can not polish to the impeller surface completely like this, can only be after polishing some on the impeller surface, change the position centre gripping of impeller again, polish to the part that does not polish again, it is very inconvenient, consequently, need a novel auxiliary fixtures of sand casting impeller.
SUMMERY OF THE UTILITY MODEL
The utility model provides a novel auxiliary fixtures of sand casting impeller can the technical problem who exists in the above-mentioned background of effectual solution.
In order to achieve the above object, the present invention provides the following technical solutions:
a novel auxiliary tool for sand casting of an impeller comprises an arc surface body, a fixed plug, a base and a support column detachably connected to the base, wherein an internal thread groove is formed in the bottom of the arc surface body, an external thread is arranged at the upper end of the support column, the external thread on the support column is meshed with the internal thread groove, a spring is arranged in the internal thread groove, a moving plate is connected to the bottom of the spring, two slide bars are connected to the side wall of the moving plate, slide blocks are connected to the end portions of the slide bars, two slide grooves are formed in the wall of the internal thread groove, and the two slide blocks are respectively installed in the two slide grooves; the top of the cambered surface body is detachably connected with a threaded column, and the fixed plug is sleeved on the threaded column.
Preferably, the supporting column is in threaded connection with the base.
Preferably, the cambered surface body is conical.
Preferably, the threaded column is in threaded connection with the top of the cambered surface body.
Preferably, the fixing plug is T-shaped.
The beneficial effects of the utility model reside in that:
the utility model discloses a set up the cooperation of the cambered surface body of taper and fixed stopper to fix the impeller, conveniently polish the surface of impeller. The utility model relates to an ingenious, effectual.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
FIG. 1: the utility model discloses the schematic structure.
FIG. 2: the utility model discloses a connection structure schematic diagram of department.
In the figure: 1. the device comprises an arc surface body, 2 parts of a fixed plug, 3 parts of a base, 4 parts of a support column, 5 parts of an internal thread groove, 6 parts of a spring, 7 parts of a moving plate, 8 parts of a slide rod, 9 parts of a slide block, 10 parts of a slide groove, 11 parts of a thread column, 12 parts of an impeller.
Detailed Description
The embodiments of the invention will be described in detail below with reference to the attached drawings, but the invention can be implemented in many different ways as defined and covered by the claims:
as shown in fig. 1 and fig. 2, the utility model provides a novel auxiliary fixtures of sand casting impeller, including the cambered surface body 1, fixed stopper 2, base 3 and detachable support column 4 of connecting on base 3, specific be: the supporting column 4 is in threaded connection with the base 3.
The cambered surface body 1 is conical, an internal thread groove 5 is formed in the bottom of the cambered surface body 1, an external thread is arranged at the upper end of the support column 4, and the external thread on the support column 4 is meshed with the internal thread groove 5.
The spring 6 is arranged in the inner thread groove 5, the bottom of the spring 6 is connected with the moving plate 7, two sliding rods 8 are connected to the side wall of the moving plate 7, the end portions of the sliding rods 8 are connected with sliding blocks 9, two sliding grooves 10 are formed in the groove wall of the inner thread groove 5, and the two sliding blocks 9 are respectively installed in the two sliding grooves 10, so that the moving plate 7 can vertically move in the inner thread groove 5, and can be extruded with the moving plate 7 when the support column 4 is screwed into the inner thread groove 5.
The detachable threaded column 11 that is connected with in top of the cambered surface body 1 specifically is: the threaded column 11 is in threaded connection with the top of the cambered surface body 1.
The fixing plug 2 is sleeved on the threaded column 11, and the fixing plug 2 is T-shaped, so that the fixing plug 2 can move up and down when the fixing plug 2 rotates on the threaded column 11.
The working principle is as follows:
install support column 4 on base 3, then be connected the external screw thread of cambered surface body 1 upper end through rotatory and support column 4, then threaded column 11 is installed at the top of cambered surface body 1 through the rotation.
Aim at screw post 11 with impeller 12's hole, then the cover is on the cambered surface body 1, because the conical shape of the cambered surface body 1, impeller 12 can hang a certain position on the cambered surface body 1, then overlaps fixed stopper 2 on screw post 11 through the rotation, and the bottom of fixed stopper 2 can get into in impeller 12's the hole, like this, through fixed stopper 2 and cambered surface body 1 to fix impeller 12, then polish impeller 12's surface.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, if the method and the technical solution of the present invention are adopted, the present invention can be directly applied to other occasions without substantial improvement, and the present invention is within the protection scope of the present invention.
