Lead screw counter-pulling sliding table module

Abstract

The invention discloses a lead screw counter-pulling sliding table module. The module comprises a base, a servo motor and a ball screw, wherein one end of the base is fixed with a motor mounting plate, the other end of the base is provided with an end cover plate, two parallel slide rails are arranged on the base between the motor mounting plate and the end cover plate, the ball screw is arrangedbetween the two slide rails, a moving plate is fixed on a nut of the ball screw, the moving plate is slidably arranged on the slide rails, two ends of a screw rod of the ball screw are installed on lead screw bearing supporting seats, one end of the screw rod penetrates through the corresponding lead screw bearing supporting seat and is connected with an output shaft of the servo motor installed on the motor mounting plate through a coupling, counter-pulling supports are further arranged on the outer sides of the lead screw bearing supporting seats at the two ends of the base, and two ends ofthe screw rod are arranged in the counter-pulling supports correspondingly. According to the module, the lead screw counter-pulling supports are arranged at the two ends of the screw rod, so that thephenomenon that the lead screw is jittered when the moving plate runs at a high speed and the lead screw is bent when the load is heavy is solved, and meanwhile, the problem of loss of the positioningprecision of the ball screw is solved.

Description

technical field [0001] The invention relates to a slide module, in particular to a slide module pulled by a pair of screw rods. Background technique [0002] At this stage, with the advancement of industrial mechanization, mechanical transmission devices have been widely used in various types of equipment. Mechanical transmission devices have certain advanced features, but there are still many problems. The design structure is complex, the transmission is not portable, and the transmission load is small. High failure rate, difficult maintenance, inaccurate positioning and high noise are the biggest disadvantages of the current mechanical transmission device. Due to the characteristic of linear movement, the sliding table device is widely used in industrial machines, and it needs to carry out linear movement to load the working mechanism, so that the working mechanism can be driven by the linear slide rail to move in a straight line, which is beneficial to calibration and ope...

AI Technical Summary

Problems solved by technology

[0003] The existing screw slide module mainly connects the shaft end of the screw rod through the shaft coupling of the servo motor, the rotation of the motor shaft drives the rotation of the screw rod, the screw nut drives the moving plate for linear motion, and the linear slide rail is used for moving the moving block Guiding and load action; but when the load above the moving block is heavy, the screw bending phenomenon occurs during the driving process of the screw, resulting in loss of positioning accuracy, and has a direct impact on the service life of the screw, especially when the moving block has When the stroke is long, it will seriously affect the positioning accuracy of the moving block, and when the moving block runs at high speed, the screw will vibrate obviously
