Description
Technical Field
The utility model relates to a calibration and detection of screw plug gauge are the auxiliary device who is used for enlarging SJ5200-100 screw thread measuring machine range particularly.
Background
The detection of the thread plug gauge is that a thread measuring machine (hereinafter, referred to as a threading machine) performs contact measurement through slippage of upper and lower threads on the surface of the measured plug gauge and a T-shaped measuring needle, and then parameter indexes such as major diameter, intermediate diameter, thread form angle, flank angle, thread pitch and the like of the thread plug gauge are automatically calculated. During detection, the clamp is placed on a threading machine, one end of the detected thread plug gauge is horizontally placed in the V-shaped groove of the clamp, the other end of the detected thread plug gauge is propped by a movable device on the threading machine, the stable horizontal placement of the thread plug gauge is kept, and the direction of the thread of the detected plug gauge is horizontal and equivalent.
Because the specification of screw plug gauge is more, so the screw plug gauge of different specifications need select the anchor clamps of different models. SJ5200-100 screw machine detects screw plug gauge includes the anchor clamps of 3 models: 1. the model P-3-20 is used for detecting a screw plug gauge with the diameter of 3mm-20 mm; 2. the model P-20-60 is used for detecting the thread plug gauge with the diameter of 20mm-60 mm; 3. the model P-45-90 is used for detecting the thread plug gauge with the diameter of 45mm-90 mm. Therefore, the SJ5200-100 threading machine can only detect the screw plug gauge with the diameter of 3mm-90 mm. For the thread plug gauge with the diameter smaller than 3mm, the end face of the thread plug gauge is mostly a tip, so that the thread plug gauge is very easy to penetrate into a needle moving round hole of a clamp P-3-20 in a V-shaped groove and cannot be detected; or the distance between the thread and the handle is too short to be horizontally placed in the V-shaped groove, so that the reliability of data can be influenced although the detection is realized.
Although a threading machine capable of detecting thread plug gauges with the diameters of 1mm-3mm is not lacked in the market, the number of the thread plug gauges with smaller diameters is not large, and therefore, a threading machine with wide measuring range and higher price is purchased, and the cost performance is extremely low.
Aiming at the defects in the prior art, the utility model provides an auxiliary device for enlarging the measuring range of a SJ5200-100 thread measuring machine, which has simple structure, easy manufacture and convenient use. With the help of the utility model, the screw plug gauge with the diameter less than 3mm can be calibrated and detected by an SJ5200-100 screw thread measuring machine.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an auxiliary device for enlarging the measuring range of SJ5200-100 thread measuring machine, which has simple structure, easy manufacture and convenient use.
