Abstract
The utility model discloses an indexing protractor for machining, which aims to improve the measuring accuracy and achieve the advantages of simple structure, low cost, speediness, convenience, stable performance and attractive shape. The indexing protractor includes a master disc, a rotating shaft, an amplifier, a travel disc, a slide rod ruler, an upper clamping piece, a lower clamping piece and a slider, wherein the master disc, the travel disc, the slide rod ruler, the upper clamping piece and the lower clamping piece are fixed on the rotating shaft and rotate around the rotating shaft; the amplifier is fixed on the travel disc, the upper clamping piece and the lower clamping piece are used for clamping objects through the rotating shaft; and the slider can slide upwards and downwards along the slide rod ruler.
Description
Technical field
The utility model relates to the machining field of measuring technique.It specifically is a kind of machining calibration protractor.
Background technology
The precision of measuring workpieces is not fine at present, influences measurement effect.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of measuring accuracy height, simple in structure, expense is low, and is quick and convenient, stable performance, machining calibration protractor aesthetic in appearance.
The utility model comprises master, rotating shaft, amplifier, trip dish, litter ruler, upper clamp slice, following card, slider; Master, trip dish, litter ruler, upper clamp slice and following card are fixed in the rotating shaft, can rotate around the shaft; Fixedly on the trip dish, following card and play card are used for blocking object by the rotating shaft rotation to amplifier, and slider can slide up and down along the litter ruler.
The trip dish is made up of 20 scales, these 20 scales are divided into 20 parts to master unit's 1 degree, the actual number of degrees should be 0.95 degree, so can be as accurate as 0.05 degree, when a certain scale mark of trip dish aligns with master, the master scale with the trip dial scale and be exactly the angle of object, during the radius R of the design's master=180/ ∏ mm, radian between two every adjacent scales of master is long to be 1mm, when the radius r of trip dish=R, its corresponding arc length is 0.95mm, because 1mm and 0.95mm differ very little, thus the radius r of increase trip dish, and on the trip dish with having an amplifier, we can watch master in the amplifier with eyes, the scale mark positions aligning of trip dish just can sense data.
Card is necessary for smooth, the horizontal object of standard.
Master is by iron, and the trip dish is by the plastics manufacturing.
Description of drawings
Fig. 1 is a structural representation of the present utility model, among the figure 1, master, and 2, rotating shaft, 3, amplifier, 4, the trip dish, 5, the litter ruler, 6, upper clamp slice, 7, card down, 8, slider.
Embodiment:
Measure the right angle with the litter ruler, by the litter length on limit of to take measurement of an angle of sliding, can accurately measure its value, the trip dish is made up of 20 scales, these 20 scales are divided into 20 parts to master unit's 1 degree, the actual number of degrees should be 0.95 degree, so can be as accurate as 0.05 degree, when a certain scale mark of trip dish and master at that time, the master scale with the trip dial scale and be exactly the angle of object, upper clamp slice and following card rotate by rotating shaft and are used for blocking object, and amplifier is installed in and is used to amplify scale on the trip dish, can clearly see scale with eyes.
Claims (4)
1. machining calibration protractor is characterized in that comprising master, rotating shaft, amplifier, trip dish, litter ruler, upper clamp slice, following card, slider; Master, trip dish, litter ruler, upper clamp slice and following card are fixed in the rotating shaft, can rotate around the shaft; Fixedly on the trip dish, following card and play card are used for blocking object by the rotating shaft rotation to amplifier, and slider can slide up and down along the litter ruler.
