Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1-8: an automatic clamp special for a flange comprises a clamp body and a feeding servo system;

the clamp body comprises two 120-degree V-shaped blocks 8 and a sliding block 5, gray cast iron HT200 is selected as a material, the two 120-degree V-shaped blocks 8 are good in centering performance, a workpiece is conveniently placed in the clamp, a clamping surface of the clamp needs to have certain position degree requirements on a sliding guide rail 10, in order to reduce positioning errors, the clamp is used as a main positioning reference surface, a supporting surface of a screw 7 is used as an auxiliary positioning surface, the freedom degree of the flange is limited, the flange cannot slide in the clamp, and the flange cannot rotate in the clamp due to the fact that the force of the clamping surface driven by a motor is far greater than the force of the flange sliding, namely the scheme limits 4 degrees of freedom of the flange. The sliding block 5 is connected with the V-shaped block 8 through a taper pin positioning 6 and a slotted screw 7, so that the two blocks are relatively fixed;

the feeding servo system comprises a servo motor 1, the servo motor 1 is fixed on a base 16 and is connected with a first screw rod 13 through a coupler 2, the first screw rod 13 is connected with a sliding block 5 through a nut 12, the sliding block 5 is connected with a guide rail 10, when the servo motor 1 starts to work, the servo motor 1 drives the first screw rod 13 to rotate through the coupler 2, the first screw rod 13 is fixed by a deep groove ball bearing 4 and rotates relative to the nut 12, the nut 12 is fixed on the sliding block 5, and therefore when the sliding block 5 is driven to move, a clamping seat of a V-shaped block 8 generates feeding displacement, and a workpiece is clamped;

the base 16 is mainly used for fixing the servo motor 1 and the guide rail 10 and limiting the axial movement of the first screw 13;

the guide rail 10 is fixed on the base 16, and the sliding block 5 slides on the guide rail 10 to generate relative motion;

the type selection of the servo motor is as follows: 40st-m 00330; selecting the coupler type: a high-precision plum coupling LM-14;

the flange special automatic clamp is designed on the basis of the theory such as material mechanics, modern structure tests and optimization design from the aspects of the structure of the flange special automatic clamp, and the technology such as two-dimensional and three-dimensional modeling software and mechanical optimization design is utilized.

The clamping device of the application adopts the 120-degree V-shaped block 8 to clamp the workpiece. The device adopts a feeding servo system for full-automatic control.

The automatic clamp special for the flange is designed with a full-automatic clamping technology, overcomes the technical defects of the traditional common manual operation flange detection, achieves the purpose of clamping the flange once and detecting and processing, improves the working efficiency and reduces the detection cost.
