Description

Tool for measuring rigidity of diaphragm capsule

Technical Field

The utility model relates to the technical field of measuring tools, in particular to a tool for measuring rigidity of a diaphragm capsule.

Background

Part of valve products in an air conditioning system of a military aircraft need to adjust the system pressure according to the requirement to ensure the system pressure to be stable, and a main component for sensing pressure change in the products to adjust is a diaphragm capsule, as shown in fig. 1. The vacuum inside the bellows and the pressure difference between the inside and the outside can stretch the bellows to work, the rigidity of the bellows is unqualified, the stretching amount is out of tolerance, and the product performance is affected. The original method for measuring the rigidity of the diaphragm capsule needs to use a bracket to fix and stretch the diaphragm capsule, a dial indicator is arranged on a magnetometer frame to measure the stretching amount of the diaphragm capsule, and an external pressure sensor is used to measure the load generated by the stretching of the diaphragm capsule. The method has the advantages that the number of measuring tools used is large, the tools need to be fixed and adjusted one by one, the use is inconvenient, the measurement efficiency is low, and the separated measurement components can cause more error interference and low measurement precision, so that the tool for conveniently, efficiently and accurately measuring the rigidity of the diaphragm capsule needs to be designed

In the figure: 1. a handle; 2. a screw rod; 3. a force value sensor; 4. a displacement sensor; 5. a base; 6. a bracket; 7. an adapter; 8. a fixing ring; 9. and a positioning ring.

Detailed Description

In order that the manner in which the utility model is attained, as well as the features and advantages thereof, will be readily understood, a more particular description of the utility model will be rendered by reference to the appended drawings.

As shown in figures 2 to 3, the tool for measuring the rigidity of the diaphragm capsule has the advantages that the overall structural dimension is about 250mm multiplied by 350mm multiplied by 510mm, the dimension is moderate, and when the tool is used, components such as a sensor, a bracket, a clamp and the like do not need to be connected one by one, so that the tool is beneficial to operation and convenient to move, and mainly comprises a handle 1, a screw rod 2, a force value sensor 3, a displacement sensor 4, a base 5, a bracket 6, an adapter 7, a fixing ring 8, a positioning ring 9 and the like.

The screw rod 2 is vertically arranged on the bracket 6, and the force value sensor 3 and the displacement sensor 4 are fixedly connected with a screw rod nut on the screw rod 2 through connecting sheets and bolts and can rotate along with the screw rod 2 to generate displacement. The handle 1 is mounted on top of the screw 2. The adapter 7 is installed at the lower end of the force value sensor 3 and is used for connecting the force value sensor 3 with the diaphragm capsule. The base 5 is used for placing a diaphragm capsule, two elliptical holes are respectively formed in two ends of the base 5, the base 5 can be fixed on the support 6 by penetrating through the elliptical holes through bolts, and the position of the base can be slightly adjusted according to requirements. The fixing ring 8 and the positioning ring 9 are correspondingly arranged on the base 5 and are used for positioning and fixing the diaphragm capsule.
