Fig. 3 is the measurement eedle and the simplified schematic diagram of surveyingpin plate hole in extent of the error of the utility model;
Fig. 4 is the simplified schematic diagram of the measurement eedle of the utility model when identical with surveyingpin plate hole diameter.
Embodiment:
With specific embodiment the utility model is further described below, referring to Fig. 1-4:
The needle plate hole and the eccentric measurement mechanism of eedle that are used for sewing machine; Comprise and measure eedle 10 and can be arranged on the measurement needle plate 20 on the support 40; Measure needle plate 20 and be provided with needle plate hole 201, measure eedle 10 and can stretch into the cylinder in the needle plate hole 201 of measuring needle plate 20 for shank 50 upper and lower parts that top can be arranged on head 30.
Upper and lower right cylinder 101,102 compositions that above-mentioned cylinder is served as reasons and is provided with one heart, the diameter of following cylinder 102 is less than the diameter of last cylinder 101, and the following cylinder 102 of measuring eedle 10 stretches into and is arranged in the needle plate hole 201.
Above-mentioned measurement needle plate 20 have with support 40 on the profile that matches of needle plate slot.
The use of the utility model:
During detection, be installed on the needle plate slot of support 40 measuring needle plate 10, small column 101 ends of measuring eedle 10 stretch into the needle plate hole of measuring on the needle plate 20 201, and big column 101 ends are installed on the shank 50.After installing, measure the eccentric data of eedle 10 in needle plate hole 201, calculate eccentric ratio.If the eccentric ratio between the needle plate hole 201 of the measurement eedle 10 of corresponding specification and measurement needle plate 20 is in specialized range; Then be specification product; If not in specialized range, then can finely tune the position of measuring eedle 10 or measuring needle plate 20, finally make eccentric data drop in the specialized range till.
