Description
【技术领域】【Technical field】
本发明涉及螺母生产设备的技术领域，特别是一种螺母硬度检测装置的技术领域。The invention relates to the technical field of nut production equipment, in particular to the technical field of a nut hardness testing device.
【背景技术】【Background technique】
螺母就是螺帽，与螺栓或螺杆拧在一起用来起紧固作用的零件，作为机械设备中的重要组成部件，螺母一直都在机械设备中与螺栓配合成为重要的紧固部件之一，螺母的强度也决定的其在机械设备中的稳定性，而螺母的硬度则是衡量螺母强度的标准之一。因此，在螺母的加工生产中，需要对螺母表面进行硬度检测，以检查其是否达到生产需求。A nut is a nut, a part that is screwed together with a bolt or a screw for fastening. As an important component in mechanical equipment, a nut has always cooperated with a bolt in mechanical equipment to become one of the important fastening components. Nut The strength of the nut also determines its stability in mechanical equipment, and the hardness of the nut is one of the standards to measure the strength of the nut. Therefore, in the processing and production of nuts, it is necessary to test the hardness of the nut surface to check whether it meets the production requirements.
目前在对螺母硬度检测时，都是通过驱动装置使得硬度计与螺母之间的压力越来越大，接着将压力传递到数据处理装置内部，数据经过处理后便能够通过数据显示装置直观的反应出来，对螺母的硬度进行检测。然而目前用于对待检测螺母的承载台，其结构较为简单，仅放置螺母于其上方，并未对螺母进行固定，以至于螺母在进行硬度检测时，容易出现晃动位移，给检测工作带来了不便，实用性较低。At present, when testing the hardness of nuts, the pressure between the hardness tester and the nut is increased through the driving device, and then the pressure is transmitted to the inside of the data processing device. After the data is processed, it can be intuitively reflected by the data display device. Come out and test the hardness of the nut. However, the structure of the bearing platform used for the nuts to be tested is relatively simple. Only the nuts are placed on it, and the nuts are not fixed, so that the nuts are prone to shaking and displacement during hardness testing, which brings difficulties to the testing work. Inconvenient and less practical.
为了固定螺母提升螺母的检测效率，CN207163833U提出了一种便于螺母硬度检测装置，通过弹簧与固定板的设置，可以有效的提高该装置的夹紧效果，从而使得螺母在检测过程中不会出现晃动飞出放置台的现象，进而能够提高装置的稳定性。In order to fix the nut and improve the detection efficiency of the nut, CN207163833U proposes a device for detecting the hardness of the nut, which can effectively improve the clamping effect of the device through the arrangement of the spring and the fixed plate, so that the nut will not shake during the detection process The phenomenon of flying out of the placement table can improve the stability of the device.
上述CN207163833U虽然解决了固定螺母提升螺母的检测效率的问题，但是存在以下不足：Although above-mentioned CN207163833U has solved the problem of the detection efficiency of fixing nut lifting nut, there are following deficiencies:
螺母通过弹簧弹力夹持固定，螺母与硬度计存在夹角时容易受力偏移，同时在放置台移动震荡情况下螺母固定位置容易产生波动，螺母固定位置不能调节，当需要进行多点硬度检测时无法快速调节对应螺母位置进行检测。The nut is clamped and fixed by spring force. When there is an angle between the nut and the hardness tester, it is easy to be displaced by force. At the same time, the fixed position of the nut is easy to fluctuate when the table moves and oscillates. The fixed position of the nut cannot be adjusted. When multi-point hardness testing is required It is impossible to quickly adjust the position of the corresponding nut for detection.
