At the same time, the machine can be tested and processed according to GB, ISO, JIS, ASTM, DIN and a variety of standards provided by users, and has good scalability. The computer system controls the rotation of the servo motor through the speed control system through the all-digital controller, and drives the moving beam to rise and fall through the precision ball screw pair after deceleration by the deceleration system, and is equipped with a wide variety of test attachments to complete the tensile, compression, bending, shearing and other mechanical properties of the material. It has a very broad application prospect in the mechanical properties test of metals, non-metals, composite materials and products. It is also the testing equipment for building materials, aerospace, machinery manufacturing, wire and cable, rubber and plastic, automobile manufacturing, shock absorption systems, scientific research institutions, colleges and universities, industrial and mining enterprises, technical supervision, commodity inspection and arbitration and other departments.

Host section 

The double-space portal structure is adopted, and the main machine part is composed of four guide columns, two precision ball screws, upper beams, middle beams, and workbenches to form a floor-mounted frame, and the speed regulation system is installed in the lower part of the workbench. The AC servo motor with high speed regulation accuracy, wide range and stable performance drives the ball screw pair to rotate through the synchronous toothed belt deceleration system, and the ball screw pair drives the middle cross beam to drive the tensile auxiliary equipment (or compression, bending and other auxiliary equipment) to move up and down to realize the loading and unloading of the sample. The structure ensures that the frame has sufficient rigidity while achieving efficient and smooth transmission. Precision ball screws only bear tensile force, which effectively prolongs life and rigidity stability. The precision screw sub-loading mode and the double nut back tighten the backlash to ensure high rigidity and high dynamic performance of the system.

Portal frame structure:The overall stamped and cast aluminum alloy shell has a neat and elegant appearance.

Structural part

The arc synchronous pulley is used for deceleration, and the ball screw is driven by zero clearance, and the transmission is backlash-free, so that the precise control of the test force and deformation speed is guaranteed. After the motor is decelerated by the three-stage synchronous pulley, the screw is driven to rotate, so as to promote the moving beam to move in a linear manner at the selected speed to achieve various test functions;

Host Framework:It is made of section steel, and the surface is treated by passivation, powder spraying and baking paint.

Ball screw pair:Precision ball ball screw pair is used to ensure gap-free transmission and control accuracy. The double set of ball screws is installed on both sides of the frame, the upper end is connected with the upper cross beam bearing, the ball nut is fixedly connected with the middle movable cross beam, the lower end is connected with the lower two ends of the frame table top with the pulley, and the pulley rotation drives the ball screw to rotate, so that the middle cross beam is lifted and lowered to produce tension or pressure. The test space can also be adjusted by using the rapid lifting of the middle beam. transmission system; Installed in the lower part of the worktable, it is composed of synchronous toothed belt and synchronous toothed belt pulley, this kind of transmission system can effectively eliminate the gap and slippage phenomenon in the transmission process, and ensure the accuracy of control.

Crossbeam:It is divided into upper beam and middle beam, which is made of carbon steel plate of medium thickness, and the upper beam is a fixed beam and is installed at the uppermost end of the main engine. The middle cross beam is a movable cross beam, which is connected with the ball screw by a ball nut. The middle beam is also a key component of loading, the sensor is installed at the lower end of the middle beam, and one end of the various test attachments is also suspended on the middle beam, and the middle beam can be raised and lowered to generate tension and pressure.

Mobile control box: It is used to operate the moving beam to quickly lift and lower when adjusting the test space, with a variety of operation modes such as fast/slow, running stop, etc.

Column: made of high-carbon steel, installed on the outside of the ball screw, the upper and lower ends are fixedly connected with the upper beam and the workbench respectively, mainly used to strengthen the frame support and install the surface gusset cover.

Dust cover:It is mounted on the inside of the portal frame to protect the ball screw from dust.

Cover:It is made of aluminum alloy, which is mainly used to cover the interior of the local body, so that the appearance of the machine can be beautiful, and it can also play a protective role in the interior of the local body.
