Description

Technical Field

[0001] The utility model relates to the field of centrifugal fan production, in particular to a fixing bracket for grinding centrifugal fan blades. Background Art

[0002] After the centrifugal fan blades are produced and formed, they need to be polished to improve the quality and aesthetics of the blades. During polishing, in order to facilitate the operation, a fixed bracket is needed to fix them, so as to facilitate polishing.

[0003] However, the current fixed bracket used for grinding centrifugal fan blades has low adjustability when in use and cannot be flexibly adjusted according to blades of different lengths and inclinations, thereby affecting the clamping effect and further affecting the grinding work. Utility Model Content

[0004] The purpose of the utility model is to provide a fixing bracket for grinding centrifugal fan blades. The utility model effectively solves the technical problems raised in the background technology.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] The cam is secured to the upper edge of the support frame, and the cam is secured to the lower edge of the support frame by a spring, which allows the cam to slide freely in the upper edge of the support frame.

[0007] As a further solution of the present invention, the structure of the clamp 2 is the same as that of the clamp 1, and the height of the clamp 2 is equal to that of the clamp 1. The shaft connected to the bottom of the clamp 2 is rotatably connected to the linear slider.

[0008] As a further solution of the present invention, the support seat is U-shaped, and a rotating rod is installed through both sides of the support seat and the inside of the support plate. One end of the rotating rod is fixedly connected to gear 1, and one side of the support seat is rotatably installed with gear 2 that meshes with gear 1.

[0009] As a further solution of the present invention, a handle is welded at the outer center of the gear 2, and the handle is arranged in an L shape.

[0010] As a further solution of the present invention, the support plate is rotatably connected to the support seat via a rotating rod.

[0011] Beneficial effects of the utility model:

[0012] The utility model provides a slide rail with an arc-shaped slide groove, and the second clamp can be moved on the surface of the slide rail by a linear slider to adjust the distance between the second clamp and the first clamp. At the same time, the slide rail slides in the arc-shaped slide groove by the arc-shaped slider, and its inclination can be adjusted in conjunction with the rotation of the rotating shaft. The first clamp and the second clamp can be rotated by the shaft, and the rotation angle can be adjusted, so that it can adapt to the fixation of blades of different specifications and inclinations, and has a wider range of applications.

[0013] During grinding, the handle can be turned to drive gear 2 to rotate, which can drive gear 1 to rotate, and then drive the rotating rod to rotate. The rotation of the rotating rod drives the support plate to tilt, thereby adjusting the fixed inclination of the blade and changing the grinding direction of the blade, thereby further facilitating the grinding operation on the blade surface.
