Embodiment example 1

[0022] as attached figure 1 As shown, the force measuring device includes a guide sleeve 1 , a test shaft 3 , a mounting plate 5 , a sensor 7 , a cover 8 and a bracket 13 . The sensor 7 is connected to the test shaft 3 through the mounting plate 5; the test shaft 3 is installed in the guide sleeve 1, and one end of the guide sleeve 1 and the bracket 13 is fixedly connected by a bolt; The contact part of the cover 8 and the adjustment rod 12 is equipped with a bearing 10. The bearing 10 and the adjustment rod 12 are fixedly installed on the cover 8 through the small cover plate 11. The adjustment rod 12 passes through the sensor 7 and forms a spiral fit with the sensor 7. Rotating the adjusting rod 12 can push the sensor 7 to move. A wheel shaft 2 is installed on the test shaft 3 , and a test pressure head 16 is fixedly mounted on the wheel shaft 2 through a pin 18 . Guide rails 6 are fixedly installed on the outer surfaces of the mounting plate 5 and the test shaft 3 respect...

Embodiment example 2

[0026] Refer to attached figure 2 , On the basis of Embodiment 1, the entire force measuring device 19 is fixedly installed on the base 21 . A fastening device 20 and a spacer 22 are installed on the base 21 .

[0027] In Example 1, different mounting bases can be selected for the force measuring device 19. During the design process, a suitable mounting base can be designed according to the shape of the component to be tested to match the moving component to ensure the accuracy of the testing process. The fastening method of the moving component can be selected according to the shape and structure of the component to be tested. The preferred fastening device can be clamped by the top screw, and the number can be selected as one or more according to the needs; at the same time, it can also be designed according to the needs Pads to ensure good contact between irregularly shaped components and the base, eliminating measurement errors caused by poor contact during the test.

Abstract

A force measuring device, including a guide sleeve, a test shaft, a mounting plate, a sensor, a cover, a bracket, and an elastic member. The sensor is connected to the test shaft through the mounting plate; the test shaft is installed in the guide sleeve, and a wheel shaft is installed on the test shaft. The test head is fixedly mounted on the axle. Guide rails are respectively installed on the outer surfaces of the mounting plate and the test shaft. An adjustment rod is mounted on the cover. Bearings are installed on the part where the cover is in contact with the adjusting rod. The elastic member is installed on the test shaft, one end is in contact with the test shaft, and the other end is in contact with the mounting plate. A sealing ring is installed between the test shaft and the guide sleeve and on the outer surface of the guide sleeve. The test device is simple in structure, easy to install, high in measurement accuracy, reliable and practical, and can realize the measurement of the force acting on a static or moving component.

Description

technical field [0001] The invention relates to a force-measuring device in the field of mechanical performance testing devices, and is particularly suitable for testing the mechanical properties of components in an environment where liquid flows through. Background technique [0002] The use of mechanical performance testing methods can improve the qualified rate of finished products before leaving the factory and ensure the reliability of products during use. At present, the commonly used method for product mechanical performance testing is to apply force to the elastic member, and measure the stress of the component by measuring the deflection or strain of the elastic member, and then judge the product performance characteristics. In the conventional measurement process, this measurement method can accurately reflect the force on the measured component. However, when the test component rotates, or when the test component performs more complex movements such as linear moti...
