Problems solved by technology

The clamping force measurement in this patent document is to obtain the micro-clamping force through the measurement method of the electronic bridge. Although it can accurately measure the clamping force, the measurement of the electronic bridge needs to use multiple circuits for signal processing. Disposal is bound to add significantly to the cost

Abstract

The invention discloses a clamping force measuring instrument and a clamping force measuring method, which are used for measuring clamping force of a clamp. The clamping force measuring instrument comprises a replaceable standard block, a spring, a clamping force indicating mechanism and a tension mechanism, wherein the standard block is suitable to be clamped by different clamps; the clamping force indicating mechanism is used for displaying magnitude of the clamping force; the tension mechanism is used for producing tension; the standard block is fixedly connected with the spring; the spring is fixedly connected with the clamping force indicating mechanism; the clamping force indicating mechanism is fixedly connected with the tension mechanism; and an indicated numerical value of the clamping force indicating mechanism is directly proportional to deformation of the spring. The invention provides a pure mechanical clamping force measuring instrument; force for pulling the standard block which is clamped in the clamp out is produced through the tension mechanism; the tension produced by the tension mechanism is intuitively indicated in the indicating mechanism through the deformation of the spring; an accurate measuring result of the clamping force of the clamp is achieved; and the instrument and the method are suitable for maintaining various clamps in a printed circuit board(PCB) industry.

Description

technical field [0001] The invention relates to the field of instrument measurement, in particular to a clamping force measuring instrument and a clamping force measuring method. Background technique [0002] In the PCB manufacturing process, there are many kinds of fixtures before and after, such as the inner thin plate fixture of the wet film line, the electroplating fixture for the electroplating line, the spraying and oven special fixture for the electrostatic spraying, etc. Due to the thickness of the product, the processing requirements and the use environment of the fixture, the size and clamping force of each fixture are also different. So far, the clamping force measurement tool for PCB fixtures has been vacant. The usual inspection of the clamping force is generally by manually pressing a spring or clamping a piece of plate, then manually pulling, and judging the clamping force based on experience. Trouble. [0003] If there is a clamping force inspection tool, ...
