Splicing and fixing structure of block gauge and device adopting the structure

Abstract

The invention discloses a splicing and fixing structure of block gauges and a device utilizing same. The block gauges are in surface contact with each other, line or point support is formed at the bottoms of the block gauges, the block gauges which are arranged on the bilateral sides are of point contact abutting structures, and accordingly the degrees of freedom of attachment is high, the accuracy is high, and the use is scientific and good in comparison with block gauge clamps in the prior art; the one side of block gauges of the block gauges which are arranged on the bilateral sides are of point contact elastic abutting structures, the fixed attachment pressing force is provided, and accordingly the size accuracy of the block gauges cannot be affected by the micro deformation caused by too large force of the block gauges; a linear guide rail is good in linearity and moves without radial clearance, mobile block gauge seats move along the direction of the linear guide rail, and accordingly the linear force is uniform and stable; in addition, block gauge supports which are used for performing supporting are arranged corresponding to the positions of supporting points of the block gauges and accordingly the micro deformation of the block gauges especially the long gauge blocks can be effectively avoided.

Description

technical field [0001] The invention belongs to the field of measuring tool inspection in the industrial technology, and in particular relates to a structure capable of splicing or fixing a plurality of block gauges and a device adopting the structure. Background technique [0002] The block gauge is simply a square block gauge, so it is called a block gauge. A set of block gauges is composed of blocks of different specifications and sizes, generally made of steel, with very high precision. To meet the needs of various workpiece size measurement. When measuring, it may be necessary to splice multiple block gauges along their lengths to achieve the required measurement length, or to fix the block gauges for easy measurement. In the prior art, the block gauge clips are generally used to splice or fix the block gauges, but these block gauge clips generally have the following defects: 1. The application is limited and limited by the size of the block gauge clips; 2. The lamina...

Problems solved by technology

In the prior art, the block gauge clips are generally used to splice or fix the block gauges, but these block gauge clips generally have the following defects: 1. The application is limited and limited by the size of the block gauge clips; 2. The lamination degree of freedom is not enough High, and the error is large; 3. The way of fitting is to use the hand lock screw to compress, and the pressing force can only be determined by the feel, which is easy to cause the block gauge to be too stressed and cause micro deformation to affect the dimensional accuracy of the block gauge; 4. For slightly longer Block gauge, there is a possibility of slight deformation
