Embodiment Construction

[0041] Please see attached Figure 1-3 , a measuring head for measuring clamping force, including a jacket 10, and the jacket 10 includes a sleeve body I and a sleeve body II. It can be seen from the figure that the cross-sections of the sleeve body I and the sleeve body II in this embodiment are rectangular . The sleeve body I and the sleeve body II are integrally formed, and of course they can also be connected into one body by means of bolt connection and the like. The jacket 10 is made of 304 steel. see image 3 , the sleeve body I is used to install the signal conversion device and the sleeve body II is used to install the linkage mechanism 6, the telescopic head 5 and other mechanical devices, which will be described in detail below. So from the appearance, the width of cover body I is greater than the width of cover body II, and the length of cover body I is then less than the length of cover body II. Both the sleeve body I and the sleeve body II are provided with a ...

Abstract

The invention relates to the technical field of measurement and provides a measuring head used for measuring clamping force. The measuring head comprises an outer cover, a connecting rod mechanism anda telescopic head; a strain gauge and a signal conversion device connected with the strain gauge are installed on the outer cover; the connecting rod mechanism controls the telescopic head to open and close; a pressing rod is connected with the connecting rod mechanism; a pressing head is connected to the pressing rod and a resilience device is arranged between the pressing head and the pressingrod; the telescopic head can open and close by operating the pressing head and the resilience device can be used for automatic resetting. The telescopic head can rotate, namely open and close, so thatcollision between the measuring head and a spring and spring damage are avoided.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to a measuring head for measuring clamping force. Background technique [0002] In the nuclear industry, grids are needed to fix the fuel rods, which requires very high clamping springs in the grids, that is, the clamping force should not be too large. If it is too large, the fuel rods will be easily broken and nuclear accident Leakage should not be too small, otherwise the fuel rods will easily slip off and the clamping effect will not be achieved. Therefore, before the grid is used, the clamping force of its spring must be tested. [0003] Chinese patent CN204301905U discloses an instrument for measuring the clamping force of the spring in the grid, which mainly uses strain gauges to detect the clamping force of the spring, and reads the data by the signal conversion module, thereby obtaining the clamping force of the spring . [0004] US Patent US20040055390A1 discloses a ...
