Linear guide rail automatic straightener

Abstract

The invention discloses a linear guide rail automatic straightener. The straightener comprises a first guide rail rack, a straightening mechanism, a second guide rail rack, an operation control plateand a PLC electric control box. The first guide rail rack and the second guide rail rack are arranged on the two sides of the straightening mechanism; and the operation control plate is connected withthe straightening mechanism and the PLC electric control box through data wires. The straightening mechanism comprises a straightening worktable, a positioning module, a guide stand column, a pressing motor, a speed reducer, a support plate, a pressing lead screw, a screw nut, a pressing connecting plate and a pressing roller; the straightening mechanism adopts three-dimensional design; the pressing motor and the speed reducer cooperate to drive the pressing lead screw so as to drive the pressing roller to press and straighten linear guide rails; and the whole set of equipment is small in floor area to save the space.

Description

technical field [0001] The invention relates to a straightening device, in particular to an automatic straightening machine for linear guide rails. Background technique [0002] Linear guides, also known as line rails, slide rails, linear guide rails, and linear slide rails, are used in linear reciprocating motion occasions, 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. [0003] Most of the existing straightening devices of linear guide rail adopt manual straightening or hydraulic semi-automatic stra...

Problems solved by technology

[0003] 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

[0004] 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 used in the production site of linear guide rails.
