Welcome to Ji'nan Bojian Testing Machine Co., Ltd.

The detector is mainly about the detection of high strength bolt connection vice, for large hexagon head high strength bolt connection vice (M27, M16, M20, M22 m2-m24, () of the coefficient of axial force, torque, torque and torsional shear type high strength bolt connection vice (, M16, M20, M22 m2-m24) pre-tightening axial force test, display and print.Device automatically loaded by cycloidal reducer, linear guide, full Chinese operation interface, computer control of high strength bolt connection vice tight, relax and reset automatically, smart tips, running process convenient and quick operation.When the axial force after reaching the standard setting, the detector will automatically record test data, through the computer automatically calculates the average axial force and average torque, sample average torque coefficient, standard deviation and coefficient of variation, and can be real-time display curve of coefficient of output torque, axial force, torque curve, etc., at the same time with parameter setting, calibration, the calibration data report printing and query function.

GB50205-2001 "code for acceptance of steel structure engineering"

[main engine] adopts horizontal structure, and the main structure adopts frame structure, so as to ensure the rigidity of the whole machine. The jig is made of high quality alloy structure, and the main drive shaft is quenched with alloy structural steel to ensure its service life. Different fixtures can be replaced according to different specimens. The installation and disassembly of the specimen are convenient and quick. The product reference map is as follows:

Drive system is driven by well-known brand electric motors. The speed regulation range is wide, the load is uniform and stable, and the control accuracy is accurate.

Transmission system adopts planetary cycloidal pinwheel reducer to ensure uniform, stable transmission and transmission accuracy. The horizontal (two chuck) space should be manually adjusted within the space. The linear movement guide part is adopted in the axial movement part to eliminate the friction force when the bolt is loaded.

[measurement and display system] the machine uses load sensors to collect the axial load of test bolts P, and the high-accuracy non-contact torque sensor collects the torque T of the sample. The computer screen shows the torque T, axial load F, torque T, axial load F curve and so on.
