Description

A kind of universal testing machine

Technical field

The utility model relates to testing machine field, in particular to a kind of universal testing machine.

Background technique

Universal testing machine integrates the Material Testing Machine of the functions such as stretching, bending, compression.

Currently, the Chinese patent that notification number is CN206906134U discloses a kind of universal testing machine, it includes lower stretching Fixture and upper stretching clamp, lower stretching clamp are moved up and down by lead screw transmission realization.When needing to detect the tensile strength of reinforcing bar, First the both ends of reinforcing bar are separately fixed on upper stretching clamp and lower stretching clamp；Then driving lead screw rotation drives lower stretch Fixture deviates from upper stretching clamp movement, so that reinforcing bar is pulled off, and then measures the tensile strength of reinforcing bar.

Although this universal testing machine is able to detect the tensile strength of reinforcing bar, but can not detect the deformation that reinforcing bar generates Length.

Utility model content

In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of universal testing machine, it can It detects reinforcing bar and generates deformation length.

The above-mentioned technical purpose of the utility model has the technical scheme that a kind of universal testing machine, Including lower seat, the seat of honour, the support column being fixed between the seat of honour and lower seat, slip base, it is provided on the slip base for clamping The upper fixture of reinforcing bar, the top surface of the lower seat are provided with mounting base, and the lower folder for clamping reinforcing bar is provided in the mounting base Tool, the seat of honour are provided with the driving source for driving slip base to rise or fall, and the slip base is fixedly linked with driving source； The top surface of the lower seat is provided with measuring rod, and the side wall of the measuring rod offers placing groove, and placing groove notch edge is set It is equipped with scale.

Through the above technical solutions, reinforcing bar can be placed into placing groove by worker, pass through observation before steel bar stretching test The scale at placing groove notch edge obtains the initial length of reinforcing bar；After steel bar stretching test, worker can will break rear reinforcing bar and put It sets in placing groove, the scale by observing placing groove notch edge obtains the breaked total length of reinforcing bar；Reinforcing bar is calculated The deformation length of generation.

Preferably, the groove width of the placing groove is gradually decreased along away from slot bottom side.

Through the above technical solutions, being not easy to drop out from the notch of placing groove, facilitating worker after reinforcing bar is placed in placing groove Detect the length of reinforcing bar.

Preferably, the upper end of the placing groove is through the top surface of measuring rod, to form opening.

Through the above technical solutions, since the groove width of placing groove is along being gradually reduced away from slot bottom side, reinforcing bar is not easy from putting Slot notch is set to enter in placing groove；It is open by setting, reinforcing bar can be put into placing groove by worker from opening, be not necessarily to from placement The notch of slot is put into, more laborsaving.

Preferably, the driving source is oil cylinder, and the power output shaft of the oil cylinder is fixed through the seat of honour and with slip base Connection.

Through the above technical solutions, oil cylinder, which can directly drive slip base, rises or falls movement, without as motor Additional transmission component is installed to be converted into moving along a straight line will circumferentially rotate, helps to reduce energy loss, improves mechanical efficiency.

Preferably, the oil pressure sensor being connected with inside oil cylinder is provided on the cylinder side wall.

Through the above technical solutions, oil pressure sensor can detecte the oil pressure of oil cylinder, worker can converse according to oil pressure The tensile strength of reinforcing bar, oil pressure sensor do not contact directly with reinforcing bar, and it is lower to be damaged possibility.

Preferably, the mounting base top surface offers the lower slot for installing lower fixture, and the bottom surface of the slip base opens up There is the upper slot for installing fixture.

Through the above technical solutions, upper fixture, lower fixture are respectively installed to slot, in lower slot, with reduce upper fixture and under The possibility that fixture collides.

Preferably, the upper fixture includes the first fixture block, the second fixture block, compact heap, and the upper slot groove width is along away from slot bottom Side is gradually reduced, and first fixture block and the second fixture block are slidably connected at respectively on the two opposite internal groove side walls of slot, for pressing from both sides Tight reinforcing bar；There are the gaps for being inserted into for compact heap between first fixture block, the second fixture block and the first slot slot bottom.

Through the above technical solutions, reinforcing bar is first inserted into the first fixture block and the second folder when upper fixture needs to clamp reinforcing bar Between block, then compact heap is inserted into the first slot；Compact heap is abutted with the first fixture block, the second fixture block simultaneously, to drive One fixture block and the second fixture block are moved towards upper slot notch；First fixture block and the second fixture block are slided along upper slot internal groove side wall, and are mutually leaned on Closely, by steel bar clamping.

Preferably, first sliding groove is offered on the cell wall of the upper slot, the first sliding groove extends towards upper slot notch, institute It states the groove width of the first slot to be gradually reduced along away from slot bottom side, is provided with and is used for and first sliding groove on the side wall of first fixture block The first sliding block being slidably connected.

Through the above technical solutions, when the first sliding block is slidably connected in first sliding groove, the first sliding block and first sliding groove Internal groove side wall abuts, and is separated with limiting the first fixture block with upper slot.

In conclusion the utility model has the beneficial effect that above-mentioned universal testing machine can detecte in contrast to the prior art The deformation that reinforcing bar generates；By being provided with oil cylinder, directly drives slip base and rise or fall movement, to reduce energy loss.
