Multifunctional portable force gauge

Abstract

The invention relates to a multifunctional portable ergometer which is only a few kilograms in weight and can be carried about and used as a tool. The ergometer can perform strength detection on materials and articles on site and perform measuring accuracy detection and standard force exertion on a measuring apparatus. The ergometer is mainly formed by assembly of a gantry support, a spiral jack, a standard area force exertion plate, a high-precision sensor, a display instrument, a micro printer, batteries and other parts by adoption of a proper mechanical structure means.

Description

Technical field:

[0001] The invention relates to a novel multifunctional portable dynamometer capable of testing the strength of materials and items, measuring accuracy of measuring equipment and applying standard forces at the work site. Weighing only a few kilograms, it can be carried around and used as a tool. Background technique:

[0002] At present, the existing material testing machines or dynamometers for testing the strength of materials are very large in size and heavy in weight, making it difficult to move them. Therefore, generally it can only be fixedly installed in the laboratory. Therefore, the existing work of testing the strength of material objects can only be carried out in the laboratory. The specific method is to take a small amount of samples and send them to the laboratory for strength testing or standard force application on a fixedly installed material testing machine or force measuring machine. The main disadvantages of this method are: sometimes...

Examples

Embodiment Construction

[0033] The purpose of the present invention is achieved like this: the lifting of the pressure plate of the screw jack or the dynamometer itself is the force source; the high-precision sensor is used as the force-measuring element; the sensor signal and the display force value are measured with a display instrument; Test data; use a 6V battery as a working power supply; connect and assemble with an appropriate mechanical structure; form a standard force application and measurement device. Perform strength testing on materials and items, test measurement accuracy on measuring equipment, and apply standard force to objects. details as follows:

[0034] Set the force unit to apply force to the object:

[0035] The force unit consists of a screw jack, a gantry bracket, a jack support plate, a rotating sleeve, a pressure plate, and a sensor force shaft.

[0036] The screw jack is a finished product. It is placed between the object to be measured and the gantry support. It can be ...
