Problems solved by technology

However, in this method, there is always a parallelism error between the track raceway and the track reference surface, and there is also a certain error in the straightness of the installation reference surface. After these two errors are accumulated, the actual trajectory of the track can be realized very quickly. High straightness is quite difficult, and the cumulative error can only be reduced by improving the track accuracy level and the machining accuracy of the mounting reference surface, which will inevitably lead to a significant increase in use costs, and the cumulative error cannot be completely eliminated. The side 4 is also useless and cannot be completely close

Embodiment Construction

[0022] The positioning and clamping method of a linear guide rail as shown in Figure 2 mainly involves the installation base 1, the track 2, and the track fixing screws 3. The special feature is that firstly, the track 2 is installed on the corresponding Reserve the position, and adjust the straightness and mutual parallelism of each track at the same time; after that, lock the track 2 through the track fixing screw 3; then, attach the upper clamp block 5 on both sides of the track 2; then, provide the The clamping stress makes the clamping blocks close to both sides of the track, and the symmetrical clamping blocks 5 on both sides of the track 2 are sequentially locked with screws, and the pins 6 are used to position the clamping blocks 5, so that the clamping stress of the clamp 7 becomes that of the clamping block 5. Clamping force; finally withdraw the fixture 7, so that the clamping force of the clamping block 5 becomes the fixed pre-tightening force of the track 2. In or...

Abstract

The invention relates to a positioning and clamping method for a linear guide rail, which belongs to the technical field of a rail fixture for adjusting and fixing the position of the guide rail. Upper clamping blocks are attached to both sides of the guide rail, so that the squeezing stress of a clamper is converted into the clamping force of the clamping blocks and the clamping force of the clamping blocks is then converted into the pretightening force for fixing the guide rail, thereby the straightness accuracy of the linear guide rail can be accurately matched and effectively positioned, consequently the positioning and clamping method for the linear guide rail avoids high-cost investment for improving the accuracy grade of the guide rail and the processing precision of assembly of a reference surface, and really improves the rigidity and the stability of the guide rail.

Description

technical field [0001] The invention relates to a positioning and clamping method, in particular to a positioning and clamping method of a linear guide rail, and belongs to the technical field of track fixtures for adjusting the position of a linear rolling track. Background technique [0002] The rolling linear guide used in the existing processing machinery is composed of a track and a slider. The track is generally composed of symmetrical even-numbered raceways to form a motion track. The raceways generally have two types of plane and arc. Slender strip type, relatively less rigid. For the convenience of installation, the bottom surface and one side of the track are generally used as the track reference plane of the track, but due to the objective existence of machining errors, there is always a parallelism error between the track reference plane and the actual track formed by the paired raceways. In other words, if you want to achieve a high straightness trajectory, the...
