Mechanical device of a flat thread automatic measuring system

Abstract

The invention discloses a mechanical device of an automatic planar thread measurement system. The mechanical device comprises a tracking type polar radius measurement mechanism and a leveling and aligning polar angle spindle mechanism. The tracking type polar radius measurement mechanism is used for measuring the polar radius of planar thread wire coiling workpieces, and the leveling and aligning polar angle spindle mechanism is used for detecting the rotation angle and adjusting the planar thread wire coiling workpieces. A guide rail installation box of the tracking type polar radius measurement mechanism is arranged on a work table through a screw rod lifting seat and moves up and down along a screw rod on the screw rod lifting seat. The leveling and aligning polar angle spindle mechanism is arranged on the work table which is located below one side of the tracking type polar radius measurement mechanism. The mechanical device is mainly used for detecting planar thread spiral lines, a driving head can be in contact with the planar thread outer spiral faces all the time, a measuring head tracks the driving head and is only in contact with the workpieces in measurement, an optical grating reading head is driven to measure the workpieces, and influence on measurement errors due to abrasion of the measuring head is avoided.

Description

technical field [0001] The invention relates to a plane thread measuring device, in particular to a mechanical device of a plane thread automatic measuring system. Background technique [0002] When a moving point in the plane moves at a constant speed along a straight line, and at the same time, the line moves around a point on the line at a constant speed, then the track of the moving point is a plane spiral, and the shape formed along the spiral has a specified tooth. The continuous protrusion of the shape is the flat thread. In many occasions of industrial production, accurate measurement of flat threads is required. At present, the more common method is tool microscopy. [0003] Due to the limitations of detection technology and equipment, most chuck manufacturers in my country still use the static subpoint measurement method, that is, the combination of a universal tool microscope and a dial to detect the helical error of the plane thread, and it takes about 30 minut...
