A slide performance testing device and testing method for linear guide rail
ActiveCN117433766BImprove adaptabilityImprove convenienceMachine part testingClassical mechanicsStructural engineering
The present invention discloses a slider performance test device for a linear guide rail, which relates to the technical field of slider performance test, and includes a support base plate, an adjustment component is installed on the top of the support base plate, and two groups of relatively arranged fixing components are installed on both sides of the adjustment component, and the fixing components are used to fix linear guide rails of different sizes. The present invention is installed with a fixing component, and a first servo motor is started to move two groups of relative L-shaped fixing plates toward the two ends of a bidirectional screw rod, and the linear guide rail corresponding to the slider to be tested is placed on the top of the two groups of L-shaped fixing plates, and the bidirectional screw rod is rotated in the opposite direction to drive the two groups of relative L-shaped fixing plates installed on the outer surface of the bidirectional screw rod to move toward the middle of the bidirectional screw rod, and the linear guide rail is clamped and fixed. The L-shaped fixing plate can adapt to L-shaped fixing plates of different widths through the adjustment component, which can solve the problem that the slider performance test device cannot adjust the width and can only fix a linear guide rail of one size.
