The electrical connection of infrared remote receiver 72 is to receive the electric signal that infrared remote receiver 72 is fed back.When the hand of operator is run in testing machine
When protruding into body 1, the infrared light that infrared transmitter 71 is radiated on infrared remote receiver 72 is kept off, and infrared remote receiver 72 is to
One controller 33 feeds back electric signal, and the first controller 33 controls alarm equipment alarm, reminds operator with this, it is hidden to reduce safety
Suffer from.
Gas nozzle 6 is provided on pedestal 2,6 side wall of gas nozzle is welded and fixed with pedestal 2, appendix is communicated on gas nozzle 6, with this
Supply 6 high pressure gas of gas nozzle.Gas nozzle 6 is opposite with 2 surface of pedestal, and the side opposite with gas nozzle 6 is placed with waste material cylinder on pedestal 2
61, waste material cylinder 61 tilts upward in cylindrical shape and opening.Gas nozzle 6 blows away the clast generated after object under test fragmentation, is subtracted with this
Remaining impurity on few pedestal 2, it is convenient to detect next time, while improving the detection accuracy of pressure sensor 31.Waste material cylinder 61 is used
In the clast that reception gas nozzle 6 is blown away, facilitate the collection of clast.
The implementation principle of the present embodiment are as follows: when needing to detect object under test, start positional cylinder 51, make slide 4 and apply
52 fast approaching object under test of compressing cylinder, shortens detection time with this；When the oil cylinder 52 that presses is close with object under test, pass through lock
The piston rod for determining 53 locking positioning oil cylinder 51 of part avoids positional cylinder 51 from shortening, and starting pressure oil cylinder 52, measuring targets are applied
Pressure, when object under test breakage, pressure sensor 31 detects object under test pressure and feeds back to digital display screen by electric signal
32, digital display screen 32 shows object under test pressure, to facilitate operation personnel record and obtains the compression strength of object under test.Positioning oil
The fast pressure of 51 stretching speed of cylinder is small, and pressure oil cylinder 52 stretches, and slow pressure is big, and positional cylinder 51 and pressure oil cylinder 52 cooperate,
Detection time is reduced with this, while the oil cylinder 52 that presses is flexible slowly, to reduce security risk.
Embodiment two: referring to Fig. 6, a kind of testing machine measuring object compression strength, the difference with embodiment one is:
Offer the exocoel 512 of cylindrical shape in positional cylinder 51, the cylinder body of pressure oil cylinder 52 through positional cylinder 51 cylinder body and with
Wall slip is tightly connected in exocoel 512, is marked with oil in exocoel 512, the top and bottom end of positional cylinder 51 pass through respectively pipeline with
Oil tank 511 is connected to, and oil pump 513 is communicated between exocoel 512 and oil tank 511, and there are two oil pumps 513 and is respectively communicated with exocoel
The conveying direction at the both ends in 512, two oil pumps 513 is located at pressure oil on the contrary, two oil pumps 513 are respectively communicated in exocoel 512
The two sides of 52 cylinder body of cylinder.
The implementation principle of the present embodiment are as follows: exocoel 512 is opened up in positional cylinder 51, the cylinder body for the oil cylinder 52 that presses is in exocoel
Sliding in 512 makes 52 directional-sliding of oil cylinder that presses with this, improves the stability of pressure oil cylinder 52.Oil pump 513 conveys oil tank 511
In interior oil disengaging exocoel 512, drives positional cylinder 51 that pressure oil cylinder 52 is pushed quickly to be positioned with this, improve detection effect
Rate.
In above scheme, positional cylinder 51 quickly drives slide 4 and pressure oil cylinder 52 close to object under test, and locking piece 53 is locked
The piston rod of tight positional cylinder 51, pressure 52 measuring targets of oil cylinder pressure, pressure measuring mechanism 3 measure pressure when object under test rupture
Power detects the compression strength of object under test with this, reduces detection time, improves detection efficiency.
The embodiment of present embodiment is presently preferred embodiments of the present invention, not limits protection of the invention according to this
Range, therefore: the equivalence changes that all structures under this invention, shape, principle are done, should all be covered by protection scope of the present invention it
It is interior.
