1) Single space structure transmission principle

 

The following figure shows a single space (between two clamps 4) structure. The working principle is as follows: the drive system 6 drives the ball screw 3 through the transmission system 5, thereby driving the moving beam 1 to realize loading, and the tested piece is clamped on the clamp 4, The load of the test piece is measured by the sensor 2.

2) Differential load double space structure transmission principle

 

The following figure shows the structure of the differential load double space (the large load working space between the clamps 4 and the small load working space between the clamps 8). The working principle of the heavy load working space is the same as that of the figure 1 structure, the driving of the small load working space, The action of the transmission until the moving beam 1 is the same as the following figure, the test piece is clamped on the jig 8, and the load of the test piece is measured by the small load sensor 7.

3) Equal-load double-space structure transmission principle

 

The following figure shows the double-spaced space (the working space between the clamps 4 and the compression and bending working space between the clamps 7). The working principle is the same as that of the figure 1. The clamp 4 is used for the tensile test. The clamp 7 is used for compression and bending tests. The upper and lower space sharing load sensor 2 performs measurement.

4) External sensor three-space structure transmission principle

 

The following figure shows the structure of the attached sensor three spaces (the large load stretching working space between the clamps 4, the large load compression between the clamps 7, the bending work space, and the small load stretching work space between the clamps 4). The main structure of the load cell 8 is driven by the drive system 6 of the test space of the large load sensor 2 through the extension of the moving beam 1, and the ball screw 3 is driven by the transmission system 5, thereby driving the moving beam to achieve loading, and performing mechanical performance in different load measurement ranges. test.
