Problems solved by technology

Due to the long pressure bearing shaft of the pressure measurement device, the ordinary pressure bearing shaft is easy to bend during pressure measurement, causing damage and affecting the test accuracy; the stronger pressure bearing shaft will have a larger diameter and mass, resulting in low measurement accuracy. , Moreover, the current pressure measurement device needs to manually adjust the position every time it measures, once the position shifts, it will cause measurement deviation, especially when the pressure test device is not perpendicular to the splint, the data deviation is large and the equipment is easy to be damaged

Abstract

The invention relates to a high-precision clamping force measuring apparatus which comprises a pressure measuring device. The pressure measuring device comprises a mechanics sensor and a left bearing shaft and a right bearing shaft coaxially mounted at the two ends of the mechanics sensor; the pressure measuring device is coaxially mounted on a horizontal base; a left linear bearing and a right linear bearing are coaxially fixed at the two ends of the base respectively; the left bearing shaft and right bearing shaft at the two ends of the mechanics sensor are correspondingly mounted in the left linear bearing and right linear bearing in a sliding manner respectively; and the left linear bearing and right linear bearing are coaxially arranged. The high-precision clamping force measuring apparatus provided by the invention has a scientific and reasonable design, a simple structure and high reliability, is convenient to operate, and effectively improves the measurement accuracy; and moreover, as the bearing shaft has certain expansion amount, the pressure measuring device is effectively protected from damage, and the test efficiency is improved.

Description

technical field [0001] The invention belongs to the field of packaging testing, and relates to a packaging box anti-pressure testing device, in particular to a high-precision clamping force measuring instrument. Background technique [0002] In the process of centralized transportation of finished product packages such as refrigerators, washing machines, fitness equipment, and furniture, it is necessary to use clamping vehicles for loading and unloading, that is, to clamp the packages and stack them or unload them. During the loading and unloading process, if the clamping device If the applied pressure is not enough, the product cannot be clamped, and if the force is too high, the packaging box will be easily damaged, which in turn will cause damage to the goods in the packaging box. Therefore, it is necessary to test the required properties such as the compressive strength of the packaging box. [0003] At present, most of the packing box force testing devices only test the...
