Description
Technical field
The present invention relates to a kind of experimental rig more particularly to a kind of metallic material testing machines.
Background technique
Testing machine is that metal material, nonmetallic materials, machine components, engineering structure etc. are measured under various conditions, environment
Mechanical performance, processing performance, internal flaw and verify rotating parts dynamic unbalance amount fine measuring instrument, can be right
Material stretched, compressed, is bent, being sheared, being reversed, being impacted, fatigue, creep, persistently, relaxation, abrasion, hardness etc. tests.?
During research and probe new material, new process, new technology and new construction, testing machine is a kind of indispensable important tester
Device.In refrigeration pipeline part welding field, often needs to testing machine and drawing detection, the testing machine of the prior art are carried out to pipe group solder joint
There are transmission accuracy is low and the jiggly disadvantage of movement, and there is also the scenes of creeping during the drawing process, are not suitable for metal tube
The solder joint of road part detects.
Summary of the invention
Present invention aims to overcome that the problems of the above-mentioned prior art and a kind of high transmission accuracy is provided, movement is steady
And the metallic material testing machine without creeping phenomenon.
In order to solve the above technical problems, the present invention adopts the following technical scheme that:
A kind of metallic material testing machine is connected including pedestal and the motor being located in the pedestal with the motor
Be speed changer, what is be connected with the speed changer is worm gear, and what is be connected with the worm gear is worm screw, is connected with the worm screw
It is first bevel gear and second bevel gear, the also first ball screw being connected with the first bevel gear, with second cone
Gear be connected there are also the second ball-screw, the first ball screw be parallel to each other with the second ball-screw connect and perpendicular to
The pedestal is equipped with the first feed screw nut in the first ball screw, and second is equipped on second ball-screw
Thick stick nut, being mounted between first feed screw nut and the second feed screw nut is crossbeam, is located at the crossbeam middle position
Be upper gripper jaw, it further includes control system that lower clamping jaw, which is mounted on the pedestal immediately below the upper gripper jaw, the control system packet
Include PLC.
Compared with prior art, the invention has the benefit that
A kind of metallic material testing machine of the present invention uses worm-drive and Bevel Gear Drive, and screw rod may be implemented certainly
Lock.Testing machine of the present invention has high transmission accuracy, and movement is steady, and no creeping phenomenon, dynamic lead screw transmission is substantially rolling friction,
Frictional resistance is small, ensures that the stationarity of movement in this way, and is not in creeping phenomenon, and measuring accuracy is higher.
Detailed description of the invention
Fig. 1 is schematic diagram of the three-dimensional structure.
Specific embodiment
Referring to figure 1, a kind of metallic material testing machine, including pedestal 1 and the motor 2 being located in the pedestal 1,
What is be connected with the motor 2 is speed changer 3, and what is be connected with the speed changer 3 is worm gear 4, is with what the worm gear 4 was connected
Worm screw 5, what is be connected with the worm screw 5 is first bevel gear 6 and second bevel gear 7, is connected also with the first bevel gear 6
First ball screw 8, be connected with the second bevel gear 7 there are also the second ball-screw 9, the first ball screw 8 and the
Two ball-screws 9 be parallel to each other connection and perpendicular to the pedestal 1, in the first ball screw 8 be equipped with the first lead screw spiral shell
Mother 10 is equipped with the second feed screw nut 11 on second ball-screw 9, is mounted on first feed screw nut 10 and second
Between thick stick nut 11 is crossbeam 12, and be located at 12 middle position of crossbeam is upper gripper jaw 13, and lower clamping jaw 14 is mounted on described
It further include control system, the control system includes PLC on pedestal 1 immediately below upper gripper jaw 13.
In use, the metal tubes part both ends to drawing to be first respectively installed to the upper gripper jaw 13 and lower folder of apparatus of the present invention
On pawl 14, the present apparatus is started by control system, the rotation of motor 2 in device is driven by speed changer 3 to worm gear 4, worm gear 4
Rotation imparts power to worm screw 5, and worm screw 5 drives the first bevel gear 6 being attached thereto and second bevel gear 7 to rotate at this time, by
It is connected to first bevel gear 6 in first ball screw 8, the second ball-screw 9 is connected to second bevel gear 7, first ball screw 8
It drives the first feed screw nut 10 and the second feed screw nut 11 to move up and down with the rotation of the second ball-screw 9, is mounted on the at this time
Crossbeam 12 between one feed screw nut 10 and the second feed screw nut 11 drives the traction of upper gripper jaw 13 real to the metal tubes part of drawing
Apply pull test.Testing machine of the present invention uses worm-drive and Bevel Gear Drive, and it is self-locking to may be implemented screw rod, present invention examination
Machine is tested with high transmission accuracy, movement is steady, and no creeping phenomenon, dynamic lead screw transmission is substantially rolling friction, and frictional resistance is small,
The size of frictional resistance is almost completely irrelevant with movement velocity, ensures that the stationarity of movement in this way, and is not in climb
Row phenomenon, measuring accuracy are higher.
The above description is only the preferred embodiments of the present invention, is not intended to limit the present invention in any other form,
Any person skilled in the art is changed or is modified as equivalent variations possibly also with the technology contents of the disclosure above
Equivalent embodiment.But without departing from the concept of the present invention, above embodiments are done according to the technical essence of the invention
Any simple modification, equivalent variations and remodeling, still fall within protection scope of the present invention.
