Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather construed as embodying the utility model in accordance with the principles of the utility model.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model.

As shown in fig. 1 to 3, the present invention includes a frame 1, a rotary table 2 rotatably fixed to the frame 1, and a chuck holder 3 fixed to the rotary table 2. The rotating platform 2 adopts a fourth shaft rotating platform, and a rotating central shaft of the fourth shaft rotating platform is arranged in the middle of the rack 1. The suction cup clamp 3 comprises a clamp base 31, a limit shell 32, a vacuum suction cup 33, an air hole 331 and a vacuum pump 4, wherein the clamp base 31 is fixedly connected to the rotary table 2 by four screws by adopting a square aluminum alloy plate and adjusts a processing surface along with the rotation of the rotary table 2; the number of the limiting shells 32 is three, the three limiting shells are fixedly connected to the clamp base 31 through screws, the limiting shell 32 is a hollow square aluminum alloy shell, but the limiting shell is not limited to square or aluminum alloy, and the framework and the material can be adopted according to the requirements that the root of the blade of the machined workpiece is fork-shaped and the surface hardness is high, so that the adjustment and the improvement can be performed according to actual requirements. The lower part of the limiting shell 32 is detachably fixed on the clamp base 31 by screws and can be disassembled and replaced as required. The vacuum suction cups 33 are correspondingly arranged in the limiting shell 32, the bottom of each vacuum suction cup 33 is fixed with the clamp base 31 through screws, the adsorption force of each vacuum suction cup is larger than the cutting force of a workpiece during machining, the adsorption surface of each vacuum suction cup is usually supported by rubber to protect the surface of the workpiece, and the vacuum suction cups can be detached and replaced when necessary;

as shown in fig. 4: the air holes 331 are formed in the surface of the vacuum suction cups 33, the vacuum pump 4 is fixed to the back of the frame 1 through screws, and the air holes 331 in the three vacuum suction cups 33 are communicated with a pipeline and are communicated with the vacuum pump 4 into a whole.

Through the technical scheme, the blade with the fork-shaped blade root can be quickly positioned, clamped and unloaded, and the size of the limiting shell 32 can be adjusted according to the size of the blade root.

The method comprises the following specific steps:

the root of the blade is placed in the limiting shell 32 and pressed to the bottom to be in contact with the vacuum chuck 33, vacuum is rapidly formed between the workpiece and the vacuum chuck 33 through the air hole 331 communicated with the vacuum pump 4 to finish strong adsorption, the Z-axis freedom degree of the workpiece is limited at the moment, the X, Y-axis freedom degree of the workpiece is limited under the action of the limiting shell 32, and the workpiece is clamped.
