Abstract
The utility model relates to a computer controlling pressure tester which is used for testing the compressive strength of cement gel sand belongs to a technical field of measuring equipments. A measuring device is arranged in an upper box which is fixed at a box base; a proportional valve and a sensor are arranged in the box base and are connected with a controller by conductors; and the controller is connected with a computer by conductors to transmit signals. An automatic control device and a manual loading device of the utility model do not interfere with each other, but are independent relatively, so both the automatic control device and the manual loading device can be used as an independent device; as the proportional valve is used to conduct a closed-loop control with the computer, the loading rate can be automatically adjusted in the test with small errors and high accuracy and the test data is accurate; after the test, the data is processed by the controller and the test report can also be printed.
Description
Technical field:
The utility model relates to a kind of computer control pressure testing machine, is used to measure cement mortar compressive strength, belongs to the metering outfit technical field.
Technical background:
Before the utility model is made, in prior art, this pressure testing machine mainly by crossbeam, column, base, block, oil pump, send fuel tap, hydraulic pressure pendulum machinery force measuring machine to be formed.Difference according to measurement range hangs different stone rollers.Stone roller adopts three altogether, is carved with A, B, C printed words respectively.Wherein the A stone roller is fixed on the fork and need not pulls down, and the A stone roller is used for the 0-60kN range, and the A+B stone roller is used for the 0-150kN range, and the A+B+C stone roller is used for the 0-300kN range.Load the manual loading mode that adopts, send the opening of fuel tap to control by artificial adjusting of operator, the loading velocity error is bigger, thereby influences the accuracy of test figure.
Technology contents:
The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of can the realization in process of the test to regulate loading velocity, and the loading velocity error is little, the precision height, and test figure is the computer control pressure testing machine accurately.
Main solution of the present utility model is achieved in that
It mainly adopts base plate 7 and crossbeam 1 to be linked to be a frame by two root posts 2 and is fixed on the block 15, and oil cylinder 6 and piston 5 are installed on the base plate 7.Motor 10, oil pump 12, block 15 are fixed on the base 11, force measuring machine 16 is installed in casing 19 rear portions, it is characterized in that showing that surveying device 20 is installed in the upper box 19, upper box 19 is fixed on the casing 15, proportioning valve 8, sensor 9 are installed in the block 15, be connected with controller 24 by lead, controller 24 is connected with computing machine 23 by lead again, carries out signal and transmits.

Embodiment:
The utility model mainly adopts base plate 7 and crossbeam 1 to be linked to be a rigid mounting by two root posts 2, is fixed on the block 15.Oil cylinder 6 is a pair of precision pairs with piston 5, is installed on the base plate 7.Recessed ball seat 4 is installed on the piston 5, and male ball seat 3 cooperates with it, can adjust the depth of parallelism between the plane on bearing plate 21 and the male ball seat 3 automatically, with the accuracy of warranty test data.Operation is convenient in the front of sending fuel tap 17 and oil return valve 18 to be installed in upper box 19.Motor 10, oil pump 12 and block 15 all are fixed on the base 11, and the power of motor 10 13 passes to oil pump 12 through the V-belt, makes oil pump 12 fuel-displaced.Motor 10 and oil pump 12 are all covered on wherein by block 15.The pendulum machinery force measuring machine 16 that adopts during manual loading is installed in upper box 19 rear portions.Stone roller 14 is installed on the force measuring machine 16.Indicating value device 20 is installed in the upper box 19, and the power value is read by pointer.Upper box 19 and arranged side by side being fixed on the block 15 of frame.
Proportioning valve 8 in the automatic control system and sensor 9 are installed in the position, left back in the block 15, are connected with controller 24 by lead, and controller 24 is connected with computing machine 23 by lead again, carry out signal and transmit.Computing machine 23, controller 24 and printer 22 are installed on the table for computer 25.
Principle of work:
Controller 24 is in a circulation, at first triggers computing machine.Computing machine is sent control information and notification controller by serial port, controller reads in control information, thereby drive the rotation of proportioning valve stepper motor, realize the adjusting of spool, test power is by the hydraulic pressure transducer indirect detection and feed back to controller, controller becomes digital signal (A/D conversion) to be transferred to computing machine again this analog signal conversion, and total system has just constituted closed-loop control like this.
Compared with the prior art the utility model has the following advantages:
1, increased the automatic add load control of a cover at original structure, and newly-increased automatic control dress Put and former manual loading device, mutually noninterfere, relatively independent, all can be used as independently, device uses; 2, Adopted advanced electro-hydraulic proportional valve and computer technology to carry out closed-loop control, automatically and continuously with constant Loading velocity is tested, and has failure data protection and concentrate printing function; 3, in process of the test Can realize regulating loading velocity, loading error is little, the precision height, and test data is accurate; 4, after the off-test, Controller carries out data according to relative national standards to strength of cement automatically to be processed, and is printed by printer Go out test report.
