Clamping structure for welding of auger blade

Abstract

The invention provides a clamping structure for welding of an auger blade. The clamping structure comprises a rotating plate, wherein a supporting rod is arranged at one end of the rotating plate; a moving claw and a limiting claw are arranged at one side of the supporting rod; a pressing plate is arranged at one end of the limiting claw; a rotating bearing is arranged in the pressing plate; an extruding column is arranged at one end of the pressing plate; a limiting groove is formed in one end of the pressing plate; and a rotating frame is arranged at one end of the limiting groove. According to the clamping structure for the welding of the auger blade, the rotating bearing is mounted in two-thirds of the pressing plate; when the upper end of the pressing plate is extruded by gravitational force, the pressing plate is inclined and rotated through the gravitational force, and the extruding column is driven by the pressing plate to rotate; then the extruding column extrudes one side of the rotating frame, and the rotating frame drives an inner sliding frame to vertically move through the lever theory; in addition, a bearing is driven to rotate through the inner sliding frame, and the moving claw at one side of an outer sliding frame is driven to vertically move through the lever theory.

Description

technical field [0001] The invention belongs to the technical field of blade clamping, and in particular relates to a clamping structure. Background technique [0002] The blades of the auger are usually helical, and when the auger is in production, multiple blades need to be welded to the outside of the auger in a circular shape. During the welding process, a clamping structure needs to be used to clamp the blades to ensure that the blades Stability during welding. [0003] For example, the patent application number CN201410364993.0 discloses a blade clamping device, in particular, provides a blade clamping device for clamping a rotor blade, especially a rotor blade of a wind turbine, which includes a plurality of blades The blade clamping assembly of the clamping tool and the sensor arrangement realized to sense specific features of the rotor blade whereby the specific features enable it to be used for orienting the blade holding device relative to the rotor blade in a bl...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the above technical problems, the present invention provides a clamping structure for welding auger blades, to solve the problem that the existing clamping structure is usually claw-shaped, because the auger blades are usually helical, and the claw-shaped clamping structure is clamped inside. The holding space is usually arc-shaped, so that when the existing clamping structure clamps the blade of the auger, the contact area between the clamping structure and the blade is small, so the clamping effect of the existing clamping structure is relatively small. Poor, and the existing clamping structure is usually manual clamping. In the process of clamping, it needs to be manually clamped continuously to achieve the effect of clamping stability. When the manual loosening, the blade is easy to fall, resulting in the existing clamping structure The problem of clamping and reinforcing the blade when the blade cannot be dropped
