Fig. 1 is the front view of movable X-ray machine handle torsional fatigue pick-up unit in embodiment of the present utility model.
Fig. 2 is the side view of movable X-ray machine handle torsional fatigue pick-up unit in embodiment of the present utility model.
As shown in Figure 1 and Figure 2, movable X-ray machine handle torsional fatigue pick-up unit 100, for carrying out torsional fatigue detection to the handle 200 on movable X-ray machine, movable X-ray machine handle torsional fatigue pick-up unit 100 comprises: swing part 110, drive division 120, control part (only showing rotary encoder 131 in figure) and installation portion 140.
Swing part 110 comprises: the first swing unit 111 carrying out swinging for driving handle 200 and the second swing unit 112 be connected with the first swing unit 111 for driving the first swing unit 111 to swing.One end of first swing unit 111 is " U " type, and handle 200 lived by " U " type end yoke of the first swing unit 111, and the other end is connected with one end of the second swing unit 112 by pin 113.Pull out pin 113, the first swing unit 111 can disassemble from the second swing unit 112.
Drive division 120 swings for driving the second swing unit 112, and in the present embodiment, drive division 120 is stepper motor, wherein, and the handle that the nominal torque of stepper motor meets X-ray machine 2 ~ 4 times of defined moment of torsion when carrying out testing fatigue.The motor shaft of stepper motor is connected by tight key with one end of the second swing unit 112.The rotation of motor shaft can drive the second swing unit 112 to swing.
Control part comprises: for the setup unit (not shown) of the number of oscillations and pendulum angle that set handle 200 and control according to number of oscillations and pendulum angle the control module (not shown) that drive division 120 drives the second swing unit 112 to swing.
Control module comprises: single-chip microcomputer and rotary encoder 131, rotary encoder 131 for gather handle 200 swing angle signal and record handle 200 swing times signal, rotary encoder 131 is connected with the motor shaft of stepper motor by shaft coupling 150, single-chip microcomputer turns to according to angle signal control handle 200, controls drive division 120 drive the second swing unit 112 to stop swinging according to times signal.
Installation portion 140 is for installing swing part 110, drive division 120 and control part, and installation portion 140 is fixed by screws on movable X-ray machine, during installation, should ensure that the motor shaft of stepper motor overlaps with the pivot center of handle 200.Installation portion 140 also comprises arc 141, and arc 141 is arranged on the second swing unit 112 top, and the motor shaft of stepper motor is through the center of arc 141.
Fig. 3 is the vertical view of movable X-ray machine handle torsional fatigue pick-up unit in embodiment of the present utility model.
As shown in Figure 3, on arc 141 with the center of arc 141 for the center of circle is provided with four arcuate sockets, see with the direction in Fig. 3, two arcuate sockets are with two arcuate sockets are symmetrical about the horizontal line at the center through arc 141 below above, first stop 161 is arranged on above on two arcuate sockets, and the second stop 162 is arranged on below on two arcuate sockets.First stop 161 is equal with the maximum angle that handle 200 can reverse to side relative to horizontal angle with the second stop 162.
When rotary encoder 131 damage or power-off time, when first swing unit 111 touches the first stop 161 or the second stop 162, first stop 161 or the second stop 162 are sent to control module by alerting signal, namely control module controls drive division 120 and drives the first swing unit 111 to turn to, thus avoids drive division 120 and handle 200 to damage.
Switch (not shown), for starting or stoping control module.
The step that movable X-ray machine handle torsional fatigue pick-up unit 100 carries out detecting is as follows:
The first step: first setup unit sets number of oscillations and the pendulum angle of handle 200, and adjust the position of the first stop 161 and the second stop 162 on arc according to the maximum angle that handle 200 reverses.
Second step: Closing Switch, Single-chip Controlling stepper motor rotates, thus drives the second swing unit 112 to swing, and the second swing unit 112 drives the first swing unit 111 to swing, and the first swing unit 111 drives handle 200 to swing.Meanwhile, the angle signal that stepper motor rotates by rotary encoder 131 and rotation direction feed back to single-chip microcomputer, and when stepper motor rotational angle reaches the pendulum angle of setup unit setting, Single-chip Controlling stepper motor turns to and records number of oscillations.When handle 200 swings the number of oscillations of the setting reached, Single-chip Controlling stepper motor stops operating.
3rd step: pull out pin 113, disassembles the first swing unit 111 from the second swing unit 112, then measures the stressing conditions of handle 200 with dynamometer, judges the degree of fatigue of handle.
4th step: repeat second step and the 3rd step.
When swinging certain number of times, detecting and terminating.
Movable X-ray machine handle torsional fatigue pick-up unit 100 is carrying out in the process detected, and also stepper motor can be stopped operating by cut-off switch.
The effect of embodiment and effect
Movable X-ray machine handle torsional fatigue pick-up unit involved by the present embodiment, because the first swing unit can drive handle to swing, second swing unit can drive the first swing unit to swing, drive division can drive the second swing unit to swing, setup unit can set number of oscillations and the pendulum angle of handle, the number of oscillations that control module sets according to setup unit and pendulum angle control handle swing, thus make handle within the cycle of regulation, complete the reversed torsion campaign of the predetermined angular of up to ten thousand times, solve the problem that manually cannot complete.
In the present embodiment, the first swing unit and the second swing unit, for removably connecting, facilitate after handle swings certain number of times, measure handle stressing conditions thus the degree of fatigue judging handle.
In the present embodiment, because have stop, so can avoid owing to causing drive division and handle to damage when rotary encoder damage or power-off.
