Abstract
The invention discloses a hydraulic type universal material testing machine. The hydraulic type universal material testing machine comprises a bottom shell and a motor, wherein a stand column is mounted on the bottom shell; an upper clamp movable platform is mounted on the stand column; a vertical step shaft is mounted on the bottom shell; the step shaft is provided with a lower clamp mechanism through a shaft coupler; a test sample is clamped between the upper clamp movable platform and the lower clamp mechanism; a torque transducer is mounted on the shaft coupler; an inner-thread-free type worm wheel is mounted at the lower end of the step shaft; power of the motor is transmitted to a worm wheel and worm rod mechanism after deceleration and torque increasing through a speed reducer; the worm wheel and the step shaft rotate together so as to drive the lower clamp mechanism to rotate. Meanwhile, the test sample is acted by a torsion moment; the torque transducer is used for measuring torque stressed on the test sample.
Description
Technical field
The present invention relates to a kind of fluid pressure type material universal testing machine.
Background technology
On existing material universal testing machine, can only carry out stretching, compression, shearing, the bending test of material, can not carry out twisting test.Modern industrial technology is advocated energy-saving consumption-reducing, and the striving direction how to be project planner former plant equipment Function Extension, is also the historic mission of the epoch giving scientific worker.
Figure 1 shows that the structural representation of current material universal testing machine stretching performance test platform part, between the vertical columns (9) of former and later two blocks (3) and material universal testing machine, be connected with the form of pin (2), limit rotatablely moving of lower clamp mechanism (8).(while doing stretching experiment, the motor (5) that starts lower chuck makes it to drive worm screw (4), worm screw to drive worm gear (6), worm gear A to drive screw mandrel (7) again, make lower chuck do upward movement, to adapt to the length needs of various sample (1), and front and back stop limits rotatablely moving of lower clamp mechanism.
Summary of the invention
The object of this invention is to provide a kind of fluid pressure type material universal testing machine, on new material universal testing machine, realize and reverse function.Connect a torque sensor with the connection place of lower clamp mechanism with shaft coupling at multidiameter, realize the size of measuring its moment of torsion carry out twisting test on new material universal testing machine time.
Technical scheme of the present invention is as follows:
Fluid pressure type material universal testing machine, include drain pan, motor, column is installed on drain pan, fixture movable platform is installed on column, vertical multidiameter is installed on drain pan, multidiameter is provided with lower clamp mechanism by shaft coupling, between upper fixture movable platform and lower clamp mechanism, be gripped with sample, torque sensor is installed on shaft coupling, multidiameter lower end is provided with without I.S.S worm gear, be engaged with worm screw without I.S.S worm gear, the end of worm screw is provided with large belt wheel, motor is externally connected with two stage reducer, on two stage reducer output shaft, small pulley is installed, between large belt wheel and small pulley, be connected by belt gear.
Described multidiameter with without coordinating by linking bond between I.S.S worm gear.
The present invention removes the front and back connection of totally four pins (2) in Fig. 1, removes the rotation condition of rotation condition block (3) to lower clamp mechanism (8), and lower clamp mechanism only can be rotated; Change screw mandrel (7) into multidiameter (12), will change the worm gear (18) without internal thread into female worm gear (6), worm gear connects with key for multidiameter (19); Consider that former fractional electric motor (5) does not provide the moment of torsion that can make sample twist off, change motor (5) into powerful motor (17), by setting up a two stage reducer (16), the power of motor is slowed down and after increasing is turned round, passes to the worm-and-wheel gear of material universal testing machine elevating mechanism through speed reduction unit; Shaft coupling for connection place (11) in multidiameter (12) and lower clamp mechanism (8) connects a torque sensor (13), sample is carried out to the mensuration of moment of torsion; This process of the test is mobile to adapt to the length requirement of various sample by fixture movable platform (10) in the control of hydraulic pressure oil-feed circuit.
Processing step:
1. remove the constraint of material universal testing machine lower clamp mechanism rotation condition block.
2. change screw mandrel into multidiameter, change tapped worm gear into not tapped worm gear, between worm gear and multidiameter, use key connecting.
3. connect a torque sensor with the connection place of lower clamp mechanism with shaft coupling at multidiameter.
4. former motor is changed to a motor that power is larger.
5. set up a two stage reducer, the power that motor is transmitted slows down after increasing is turned round and reaches worm-and-wheel gear again through speed reduction unit.
Principle of work of the present invention:
Standard sample is placed between upper lower chuck and is clamped, open motor, the power of motor reaches worm-and-wheel gear after the increasing of speed reduction unit reduction of speed is turned round, worm gear rotates together with multidiameter, drive lower clamp mechanism to rotate, now sample is subject to the effect of torsional moment, and torque sensor records the torque that sample is subject to.
