A clamping structure for auger blade welding

Abstract

The invention provides a clamping structure for auger blade welding, which includes a rotating disk, one end of the rotating disk is provided with a support rod, one side of the support rod is provided with a movable claw and a limit claw, and one end of the limit claw is provided with a pressing plate , the inside of the pressing plate is provided with a rotating bearing, one end of the pressing plate is provided with an extrusion column, one end of the pressing plate is provided with a limiting groove, and one end of the limiting groove is provided with a rotating frame, which is installed at two-thirds of the position of the pressing plate. There is a rotating bearing, so that when the top of the pressing plate is squeezed by gravity, the pressing plate rotates through the gravity tilt, and the pressing plate drives the extrusion column to rotate, and then the extrusion column squeezes one side of the rotating frame, and the rotating frame is driven by the principle of leverage The inner sliding frame moves in the vertical direction, and the bearing can be driven to rotate by the inner sliding frame, and the movable claw on one side of the outer sliding frame is driven to automatically move in the vertical direction through the lever principle again.

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
