This invention relates to the field of building material testing technology, specifically a fully automatic flexural strength tester for detecting the compressive strength of concrete. The tester includes: a base, a support device, a flexural indenter device, a control system, a data display screen, and a core sample clamping device. The base supports the mechanical structure of the entire device and provides an installation reference for each component. The support device is symmetrically arranged on both sides of the upper surface of the base, supporting the core sample clamping device and providing vertical load-bearing capacity. The core sample clamping device is installed on the upper end of the support device to clamp and fix the concrete core sample specimen, ensuring the positional stability of the specimen during loading. The flexural indenter device is located above the pressure sensor and applies a concentrated load to the concrete core sample specimen to achieve the flexural strength test. This invention replaces the traditional hydraulic cylinder drive with a motor drive, eliminating influencing factors such as piston deformation, hydraulic cylinder leakage, and changes in oil quality.

A worktable for an integrated high-power laser cutting machine includes parallel rails on both sides and several crossbeams spanning across them, forming a working area between the rails on both sides. A vertically arranged partition plate is positioned above the crossbeams, dividing the working area into several working chambers. A heat-insulating protective plate is positioned on the outer side of the partition plate. The heat-insulating protective plate and the partition plate together form a heat-insulating cavity, which separates the crossbeams from the working chambers. The rails are equipped with an intelligent dust-removing and heat-dissipating duct. A heat dissipation vent is opened on one side of the intelligent dust-removing and heat-dissipating duct, connecting the duct and the working chambers. A cooling fan is connected to the intelligent dust-removing and heat-dissipating duct. This invention significantly improves the thermal stability and processing accuracy of the high-power laser cutting worktable by integrating a composite structure of a heat-insulating protective plate, partition plate, and refractory bricks, along with an active heat dissipation and dust removal system, thus enabling it to perform laser cutting operations with a high-power laser cutting machine.

This utility model relates to the field of inspection fixture technology, specifically to an inspection fixture for reinforcing steel sheet misalignment. It includes a base and a support plate on the base. A placement groove is provided in the middle of the support plate. The fixture also includes a negative pressure generator located at the lower end of the support plate, with its adsorption end extending into the placement groove. The placement groove in the middle of the support plate is used to accommodate and prevent the reinforcing steel sheet to be inspected from being obstructed. Support bars are provided to lift the reinforcing steel sheet, ensuring that the flexible circuit board and its reinforcing steel sheet can be evenly flattened under the negative pressure adsorption effect of the negative pressure generator. Simultaneously, due to the different number of positioning posts on both sides, the operator can only position the reinforcing steel sheet to be inspected in the only correct direction, effectively avoiding mis-inspection and production waste caused by incorrect orientation. This fixture can achieve stable positioning while also eliminating warping or deformation that may occur due to the flexibility of the flexible circuit board, greatly improving the accuracy and consistency of inspection results.
