Description

A linear guide rail automatic straightening machine

technical field

The utility model relates to a straightening device, in particular to an automatic straightening machine for linear guide rails.

Background technique

Linear guide rails, also known as line rails, slide rails, linear guide rails, and linear slide rails, are used in linear reciprocating motion applications, and can bear a certain torque, and can achieve high-precision linear motion under high load conditions. Linear products such as linear guides may be bent or twisted due to incomplete release of residual stress during the forming process. In addition, the linear guide rail may also be deformed during transportation, installation and use. Linear guides are precision parts and have high requirements for shape accuracy, so calibration has become an essential process and an important process in the production of linear guides.

Most of the existing straightening devices of linear guide rail adopt manual straightening or hydraulic semi-automatic straightening method. Manual straightening causes the shortcomings of excessive error, low precision and high labor cost. Low precision and overshoot phenomenon cannot meet the requirements of automatic high-precision alignment of linear guide rails.

For example, the Chinese patent with the application number 201120537187.0: a device for correcting the distortion of linear guide rails. This technical solution uses the principle of leverage and relies on artificial force to make the linear guide rails reversely twist on the rotating body and the fixed bracket to achieve twist correction. This technical solution wastes manpower, has low degree of automation, and low alignment accuracy, which is not conducive to being widely applicable to the production site of linear guide rails.
