Lead screw accuracy detector

Abstract

A lead screw accuracy detector comprises a detection table and a transverse support, wherein a grating detection device is arranged above the detection table and comprises a grating ruler, a grating data displayer and a movable support. The grating ruler is fixed on the detection table in the horizontal direction, transverse guide rails are arranged on two sides of the grating ruler, the movable support is clamped on the transverse guide rails, a grating detector is arranged on one side of the movable support close to the grating ruler, the grating data displayer is connected onto the grating detector, and a rotary lead screw positioning measuring head is arranged at the front end face of the movable support and fixed on the front end face of the movable support through a longitudinal adjusting device of the measuring head. A pneumatic clamping device is arranged on the left side and the right side of the upper portion of the detection table respectively, and the pneumatic clamping devices are connected onto a pneumatic controller through pressure pipelines. The lead screw accuracy detector can confirm lead screw accuracy fast and has the advantage of being low in production and manufacturing cost, easy to operate and the like.

Description

technical field [0001] The invention relates to a precision detector, in particular to a lead screw precision detector. Background technique [0002] At present, ball screws have been widely used in many fields, especially in some precision processing equipment. For these precision processing equipment, the precision requirements are very high, and the accuracy of the applied screw directly determines The precision of the processed products, in order to meet the use requirements of the equipment for the accuracy of the lead screw, the produced lead screw needs to be strictly screened to determine the accuracy of each lead screw to meet the use requirements of different equipment. [0003] In the past, the laser dynamic measurement system was often used to measure the pitch accuracy of the ball screw. The cost of the equipment used to detect the pitch accuracy of the ball screw by the laser dynamic measurement system is not suitable for widespread application in small and med...

Problems solved by technology

[0003] In the past, the laser dynamic measurement system was often used to measure the pitch accuracy of the ball screw. The use of the laser dynamic measurement system to detect the pitch accuracy of the ball screw is expensive, and it is not suitable for widespread application in small and medium-sized enterprises.
