3, be provided with the emergency stop switch that can carry out emergency processing to fault and emergency episode, therefore safe.
4, can utilize the mode of rotation adjusting knob that the translational speed of last anchor clamps is regulated in real time.
Description of drawings
The electronic pull force tester structural perspective of auto-manual that Fig. 1 provides for the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the electronic pull force tester of auto-manual that the utility model provides is elaborated.
As shown in Figure 1, the electronic pull force tester of auto-manual that provides of the utility model comprises board 1, column 2, fine setting piece 3, reducing motor, controller, rotary encoder, guide rail 4, leading screw 5, module, digital display type pull and push dynamometer 6, lower clamp 7 and last anchor clamps 8; Wherein the front end face of board 1 is provided with digital display screen 9 and a plurality of operating key 10, and inside is equipped with the controller that links to each other with digital display screen 9, a plurality of operating key 10, reducing motor and rotary encoder; The lower end of column 2 is fixed on the surface of board 1; Guide rail 4 and leading screw 5 vertically are arranged side by side on the front end face of column 2; Reducing motor is installed in the inside of board 1, and the back, surface that its output shaft runs through board 1 is connected with the lower end of leading screw 5, and rotary encoder is installed on the output shaft; Fine setting piece 3 is installed in the surface of board 1 in the mode that can move horizontally, and manual adjustments knob 11 is installed on the side, and the front end face of the relative column 2 of rear end face; Lower clamp 7 is installed in the surperficial rear end of fine setting piece 3, and the position can up-down adjustment; Module is installed on leading screw 5 and the guide rail 4 in the mode that can move up and down; Digital display type pull and push dynamometer 6 is arranged on the module, and the lower end is connected with anchor clamps 8.
Described a plurality of operating key 10 comprises the adjusting knob 12 that is used to regulate reducing motor speed, is used to control uplink and downlink button 13, power switch 14 and the emergency stop switch 15 that digital display type pull and push dynamometer 6 moves up and down.
The inside of described fine setting piece 3 is equipped with gear module and the frock module that is subjected to 11 controls of manual adjustments knob, wherein the gear module links to each other with lower clamp 7, be used to regulate the upright position of lower clamp 7, the frock module is used to regulate the horizontal level of fine setting piece 3 and lower clamp 7.
When needs use the electronic pull force tester of auto-manual that the utility model provides that metal material and nonmetallic materials are carried out tensile test, at first by the staff with power switch 14, and the lower end of test specimen 16 to be detected is clamped on the lower clamp 7, press then, descending button in the descending button 13, controller starts reducing motor after receiving the signal of descending button immediately, under the drive of reducing motor, leading screw 5 also will rotate, together move down thereby make the module that cooperates with leading screw 5 and be installed in the digital display type pull and push dynamometer 6 on the module and go up anchor clamps 8, near last anchor clamps 8 move to test specimen 16, in this process, controller becomes to go up the speed that anchor clamps 8 move with the motor speed data reduction of rotary encoder collection and is presented on the digital display screen 9, the staff can regulate the present speed of reducing motor by the mode of rotating adjusting knob 12, and reducing motor is worked under suitable movement velocity.Upper end with test specimen 16 is clamped on the anchor clamps 8 afterwards, the rotation manual adjusting knob 11 then, so that the fine setting piece 3 and on lower clamp 7 move horizontally, be located on the same line up to lower clamp 7 and last anchor clamps 8, to guarantee that test specimen 16 is in plumbness, promptly not having external force applies, at last by living in, up button in the descending button 13, controller starts the reducing motor reverse rotation after receiving the signal of up button immediately, under the drive of reducing motor, leading screw 5 also will be reversed rotation, together move up thereby make the module that cooperates with leading screw 5 and be installed in the digital display type pull and push dynamometer 6 on the module and go up anchor clamps 8, in this process, to demonstrate the speed uplink of digital display type pull and push dynamometer 6 on the digital display screen 9, unclamp up button after test specimen 16 fractures, the numerical value that shows on the digital display type pull and push dynamometer 6 is the pull-off force of test specimen 16 at this moment.
In addition, when breaking down in the process of the test or during abnormal conditions such as emergency episode, can utilizing the mode of pressing emergency stop switch 15 to make reducing motor out of service.
In addition, can utilize the method for regulating manual adjustments knob 11 to regulate the upright position of lower clamp 7 by the gear module according to the detection requirement of material to be detected.
