Abstract
The utility model discloses a pressure testing machine which comprises a rack, a hydraulic system, an upper bearing plate, and a lower bearing plate, wherein a stand column is arranged on the rack and is connected with an upper cross beam and a lower cross beam, an oil cylinder is arranged on the lower cross beam, a load sensor is arranged on the upper cross beam and connected with the upper bearing plate, the lower bearing plate t is arranged on a ball sea which is arranged on a screw, the screw is arranged in a nut in a sheathing manner and connected with the oil cylinder through an oil pipe, a clamping device is also arranged on the lower bearing plate, and consists of two clamping plates and a locking oil cylinder, and the two clamping plates are connected through a pin shaft. The pressure testing machine can apply and bear relatively high testing strength, and is high in testing precision as a tested piece cannot generate displacement during testing process.
Description
Technical field
The utility model relates to pressure testing machine.
Background technology
Compression tester for iron ore ball group is applicable to the mensuration of iron ore roasting pelletizing compressive strength, and compressive strength is an iron ore pellets suffered maximum pressure load while breaking completely, and its numerical value is the mean value of all Specimen Determination values in one group of sample.
Testing machine of the prior art is generally that electric lifting mechanism is installed on entablature, load sensor is installed under lower bearing plate, mode by upper depression is measured, such structure has the following disadvantages: upper bearing plate is installed on entablature, and move by electric lifting mechanism, institute's applied pressure is limited; Detected member is easily subjected to displacement between bearing plate, affects test accuracy.
Utility model content
The utility model object is to overcome above-mentioned the deficiencies in the prior art, provides a kind of larger pressure can be provided, and can keep the fixing pressure testing machine in detected member position.
The technical solution of the utility model is: a kind of pressure testing machine, comprise frame, hydraulic system, upper bearing plate, lower bearing plate, frame is provided with column, column connects entablature and sill, sill is provided with oil cylinder, described entablature is provided with load sensor, load sensor connects upper bearing plate, lower bearing plate is installed on ball seat, ball seat is installed on screw rod, screw sleeve is placed in nut and connects oil cylinder by oil pipe, on described lower bearing plate, be also provided with clamping device, clamping device comprises two grip blocks and locking cylinder, between two grip blocks, be connected by bearing pin.
Lower bearing plate carries out motion upwards by the effect of oil cylinder, can apply larger pressure, and clamping device can carry out big or small adjusting by locking cylinder according to the situation of detected member, ensures measuring accuracy.
Described entablature is fixed on column by set nut.
Such structure makes entablature on column, do displacement to a certain degree, adapts to the test of multiple intensity.
The beneficial effects of the utility model are: such structure is more firm, can apply and bear larger test intensity, and in test process, detected member can not be subjected to displacement, and measuring accuracy is high.
