霸刀分享-螺纹塞规的使用方法和注意事项
螺纹塞规是检测内螺纹尺寸和形状精度的小能手，在机械制造、汽车维修、航空航天等领域都超有用。下面就给你说说它的使用方法和注意事项。
使用方法
1. 准备工作：把被测螺纹孔和螺纹塞规都清理干净，别让油污、杂质影响检测。同时，检查一下螺纹塞规的标识清不清晰，规格型号对不对。
2. 外观检查：仔细瞧瞧螺纹塞规表面有没有裂纹、锈蚀或者磨损，还要确认螺纹牙型完不完整，有没有明显损伤。
3. 通止检测：先用通端插入被测螺纹孔，要是能顺利旋入，还没有明显卡滞感，那就说明这一步没问题。接着用止端试试，正常情况下止端是无法完全旋入的，或者旋入时有明显阻力。
4. 旋转检测：通端顺利通过后，轻轻旋转螺纹塞规，感受一下螺纹配合的松紧度。要是过松或者过紧，那螺纹可能就有问题了。
5. 深度测量（如适用）：如果螺纹孔有特定深度要求，可以用带深度刻度的螺纹塞规来校验深度。
6. 记录结果：把检测结果记下来，像通止情况、旋转松紧度，还有发现的异常都要写清楚。
注意事项
1. 力度要恰当：操作时别太用力，不然容易损坏螺纹塞规或者被测螺纹。
2. 保持干净干燥：定期清理螺纹塞规，别让灰尘、油渍影响测量结果。
3. 存放环境要好：把它放在干燥、通风的地方，避免高温、潮湿和腐蚀性气体的侵蚀。
4. 定期校准：根据使用频率和工作条件，定期对螺纹塞规进行校准，保证它的精度符合标准。
5. 做好防护：使用时戴上手套，防止划伤手指或者手部。
6. 专用性要强：不同规格型号的螺纹塞规可别混用，不然容易误判或者损坏塞规。
7. 注意螺纹方向：确保螺纹塞规和被测螺纹的方向一致，不然会导致测量误差。
只要按照这些方法使用螺纹塞规，并且注意这些事项，就能提高检测的准确性和效率，保障产品质量和生产安全啦。
The usage method and precautions of thread plug gauges
Thread plug gauges are experts at detecting the size and shape accuracy of internal threads and are extremely useful in fields such as mechanical manufacturing, automotive maintenance, and aerospace. Now I'll tell you about its usage method and precautions.
Usage method
1. Preparatory work: Clean the threaded holes and threaded plug gauges to be tested thoroughly to prevent oil stains and impurities from affecting the inspection. At the same time, check whether the marking of the thread plug gauge is clear and whether the specification and model are correct.
2. Visual inspection: Carefully examine the surface of the thread plug gauge for any cracks, rust or wear. Also, confirm whether the thread profile is complete and if there is any obvious damage.
3. Through and stop detection: First, insert the through end into the threaded hole to be tested. If it can be smoothly screwed in without any obvious jamming sensation, it indicates that this step is fine. Then try with the stop end. Under normal circumstances, the stop end cannot be fully screwed in, or there will be obvious resistance when it is screwed in.
4. Rotation detection: After the through end passes smoothly, gently rotate the thread plug gauge to feel the tightness of the thread fit. If it is too loose or too tight, there might be a problem with the thread.
5. Depth measurement (if applicable) : If the threaded hole has specific depth requirements, a threaded plug gauge with depth scale can be used to verify the depth.
6. Record the results: Write down the test results, such as the on-off status, the tightness of rotation, and any abnormalities found.
Precautions
1. The force should be appropriate: Do not apply too much force during operation, otherwise it is easy to damage the thread plug gauge or the thread being measured.
2. Keep clean and dry: Regularly clean the thread plug gauge to prevent dust and oil stains from affecting the measurement results.
3. Good storage environment: Keep it in a dry and well-ventilated place, avoiding the erosion of high temperature, humidity and corrosive gases.
4. Regular calibration: According to the usage frequency and working conditions, regularly calibrate the thread plug gauge to ensure its accuracy meets the standards.
5. Take proper precautions: Wear gloves when in use to prevent cuts on your fingers or hands.
6. Strong specificity: Do not mix and match thread plug gauges of different specifications and models, otherwise it is easy to misjudge or damage the plug gauges.
7. Pay attention to the thread direction: Ensure that the thread plug gauge is in the same direction as the thread being measured; otherwise, it will cause measurement errors.
As long as the thread plug gauge is used in accordance with these methods and these matters are noted, the accuracy and efficiency of the detection can be improved, and the product quality and production safety can be guaranteed.
