Description

Clamping device for processing semi-open impeller
Technical Field
The invention relates to a clamping device for processing a semi-open impeller, and belongs to the field of impeller processing.
Background
Impellers are widely used in many fields as core components of pumps. The whole body of the blade is generally made of materials with high strength and difficult processing, cracks and defects are not allowed, the blade is thin, the torsion resistance is large, the blade is expanded and long, the stress is easy to deform, and the processing technology is always difficult due to the deep and narrow channel between the blades, the openness is poor, and the material cutting rate is high.
The traditional open impeller clamps the blades through 3 claws or 4 claws, and the clamping position is small, so that the blades are easily clamped and broken due to overlarge clamping force; meanwhile, the machining efficiency is low, and potential safety hazards exist.
Disclosure of Invention
The invention aims to solve the problems of low processing efficiency, poor safety and the like of a traditional impeller clamping device, and provides a clamping device for processing a semi-open impeller.
The purpose of the invention is realized by the following technical scheme:
the invention discloses a clamping device for processing a semi-open impeller, which comprises a base, an active pressing mechanism arranged in the center of the upper surface of the base and a group of passive pressing mechanisms which are circumferentially distributed on the periphery of the upper surface of the base and have the same structure;
the active pressing mechanism comprises a positioning screw rod vertically fixed on the upper surface of the base, a pressing plate sleeved on the positioning screw rod and a pressing nut;
the passive pressing mechanism comprises a pressing support fixed on the upper surface of the base and a pressing connecting rod hinged to the pressing support, and a torsion spring is mounted at the hinged point of the pressing connecting rod; under the free state of the torsion spring, the inner side of the hinged point of the pressing connecting rod is lifted upwards; the pressing connecting rod is provided with an inward bending pressing part at the outer side of the hinge point;
the impeller to be processed is sleeved on the positioning screw rod in the driving pressing mechanism through the shaft hole, the lower end of the impeller to be processed is pressed downwards on the inner side of a hinge joint of a pressing connecting rod in the driven pressing mechanism, a pressing part of the pressing connecting rod, which is positioned on the outer side of the hinge joint, is used for passively pressing downwards the periphery of the impeller to be processed, and a pressing nut on the positioning screw rod in the driving pressing mechanism is screwed downwards, so that a pressing plate is pressed downwards at the middle part of the impeller to be processed, and the positioning of the impeller to be.
Advantageous effects
The clamping device can stably clamp the impeller, and does not need to clamp again in the whole machining process, so that the clamping force borne by the whole impeller and a tool is uniformly distributed, and the impeller is only required to be clamped and positioned once in the whole machining process, thereby avoiding the precision loss. Meanwhile, the hinge pressing plate can be replaced, so that the semi-open type impellers with different sizes can be flexibly adjusted, and the application range of the clamping device is greatly enlarged.
Drawings
FIG. 1 is a schematic view of a clamping device according to the present invention;
in the figure, 1-base; 2, pressing a support; 3-compressing the connecting rod; 4-impeller to be processed; 5, pressing a plate; 6, positioning a screw rod; 7-pressing the nut.
Detailed Description
The invention will be further described with reference to the following drawings and examples.
Examples
As shown in fig. 1, a clamping device for processing a semi-open impeller comprises a base 1, an active pressing mechanism arranged at the center of the upper surface of the base 1, and a group of passive pressing mechanisms with the same structure and circumferentially distributed around the upper surface of the base 1;
the active pressing mechanism comprises a positioning screw rod 6 vertically fixed on the upper surface of the base 1, a pressing plate 5 sleeved on the positioning screw rod 6 and a pressing nut 7;
the passive pressing mechanism comprises a pressing support 2 fixed on the upper surface of the base 1 and a pressing connecting rod 3 hinged to the pressing support 2, and a torsion spring is mounted at the hinged point of the pressing connecting rod 3; in a free state of the torsion spring, the inner side of the hinge point of the pressing connecting rod 3 is lifted upwards; the pressing connecting rod 3 is provided with an inward bending pressing part at the outer side of the hinge point;
the impeller 4 to be processed is sleeved on a positioning screw 6 in the driving pressing mechanism through a shaft hole, the lower end of the impeller 4 to be processed is pressed downwards on the inner side of a hinge point of a pressing connecting rod 3 in the driven pressing mechanism, a pressing part of the pressing connecting rod 3, which is positioned on the outer side of the hinge point, is pressed downwards around the impeller 4 to be processed, a pressing nut 7 on the positioning screw 6 in the driving pressing mechanism is screwed downwards, so that a pressing plate 5 is pressed downwards at the middle part of the impeller 4 to be processed, and the positioning of the impeller 4 to be processed is realized.
