Abstract

The invention discloses a hardness detection device for an all-glass vacuum blank tube, and belongs to the field of hardness testing. The hardness detection device comprises a box body, support platesfixedly connected to two sides of the upper part of the box body, a top plate fixedly connected to the upper parts of the support plates, a mounting frame mounted at the upper part of the top plate,a driving motor fixedly connected to the right side of the mounting frame, and a screw rod fixedly connected to the left side of the driving motor, a movable block is in threaded connection with the middle of the lead screw, an electric telescopic rod is fixedly connected to the lower portion of the movable block, a pressure sensor is installed on the lower portion of the electric telescopic rod,a hydraulic rod is fixedly connected to the lower portion of the top plate, a fixing plate is fixedly connected to the lower portion of the hydraulic rod, and a protective cover is installed on the lower portion of the fixing plate.A clamping seat is fixedly connected to the middle of the upper part of the box body; A clamping sleeve is installed on the upper portion of the clamping base, and a fixing screw is in threaded connection with the upper portion of the clamping sleeve. The device is simple in structure, capable of protecting the safety of detection personnel and collecting detected waste, high in practicability and worthy of use and popularization.

Description

technical field [0001] The invention relates to the field of hardness testing, in particular to a hardness testing device for an all-glass vacuum blank tube. Background technique [0002] Hardness is the ability of a material to resist pressing harder objects into its surface. According to different test methods and scope of application, hardness units can be divided into Brinell hardness, Vickers hardness, Rockwell hardness, micro-Vickers hardness, etc. Different units have different test methods, which are suitable for materials with different characteristics or occasion. [0003] The existing Chinese patent with authorized notification number CN207300774U discloses a pipe hardness detection device, which relates to the detection technology field. The pipe hardness testing device includes a base, and both sides of the top of the base are fixedly connected with a force-bearing device, and a connecting rod is arranged through the force-bearing device, and a limit device is...

Problems solved by technology

[0004] Although the above-mentioned device can increase the detection efficiency and simplify the pipe fixing operation steps, it cannot dispose of the waste of the pipe after inspection, and the glass breakage that occurs during the hardness test of all glass pipes may also endanger the safety of the inspectors. Therefore, we propose A device for testing the hardness of an all-glass vacuum blank tube
