Abstract
The invention discloses an anti-collision device of an automatic ultrasonic flaw detection system. An elastic element is sleeved outside a probe, and a protection cover is sleeved outside the elastic element. The upper end of the protection cover is connected with one end of a first connecting rod through a first hinge. The middle part of the first connecting rod is connected with one end of a mounting bracket through a second hinge. The other end of the first connecting rod is connected with one end of a second connecting rod through a third hinge. The other end of the second connecting rod is connected with one end of an inverted L-shaped connecting rod through a fourth hinge. The inverted L-shaped connecting rod is sleeved on the middle part of the mounting bracket, and the upper end face of the inverted L-shaped connecting rod is suspended at the inner side face of the mounting bracket through a spring. The lower end face of the inverted L-shaped connecting rod is connected with a micro-switch contact fixed in a fixed mount. When a foreign body hits the protection cover, the protection cover drives the first connecting rod to rotate around the second hinge so as to drive the second connecting rod to deflect a certain angle and drive the third connecting rod to move downwards to touch the micro-switch, then the moving system is stopped automatically so as to stop the movement of the probe to avoid collision of the expensive probe.
Description
Technical field
The present invention relates to the collision avoidance system of popping one's head in, especially relate to a kind of anti-collision device of automatic ultrasonic flaw detection system.
Background technology
There is purposes widely in the automatic ultrasonic inspection system at industrial circle, as is used for the automatic ultrasonic inspection system of turboshaft, the automatic ultrasonic inspection system of avigation piece etc.
Generally speaking, the probe of automatic ultrasonic inspection system directly is fixed on the moving-member, if like this when accidentally having run into the parts of foreign object or system itself when mobile under the drive of probe at moving-member, probe very easily damages, and probe is somewhat expensive, and therefore loss is bigger.
So for fear of loss, it is particularly important that the meaning of anti-collision device of automatic ultrasonic flaw detection system just seems.It will determine the degree of impairment and the ultimate life of probe.
Summary of the invention
The object of the present invention is to provide a kind of anti-collision device of automatic ultrasonic flaw detection system, thereby can protect probe not wounded reliably by foreign object at motion process.
The technical scheme that the present invention solves the problems of the technologies described above employing is:
The present invention has elastic component at probe outside cover; flexible member is with protective cover outward; the upper end of protective cover is connected with an end of first connecting rod by first hinge; the centre of first connecting rod is connected with an end of fixed mount by second hinge; the other end of first connecting rod is connected with an end of second connecting rod by the 3rd hinge; the other end of second connecting rod is connected with an end of Γ shape connecting rod by the 4th hinge; Γ shape connecting rod is enclosed within the fixed mount middle part; the upper surface of Γ shape connecting rod is hung in the fixed mount medial surface by spring simultaneously; a microswitch contact interior with being installed in fixed mount, the lower surface of Γ shape connecting rod is connected, and fixed mount and probe are installed on the same parts.
The described first hinge center and the second hinge center are not positioned on the same perpendicular line.
The beneficial effect that the present invention has is:
If automatic closing movement system make the probe stop motion, thereby the probe of protective price costliness was avoided bump effectively when anti-collision device of automatic ultrasonic flaw detection system of the present invention had foreign matter very near with it in the probe movement process.
Description of drawings
Fig. 1 is a mechanical construction drawing of the present invention.
Fig. 2 is an electrical schematic diagram of the present invention.
Among the figure: 1, probe, 2, flexible member, 3, protective cover, 4, first hinge, 5, second hinge, 6, first connecting rod, the 7, the 3rd hinge, 8, second connecting rod, the 9, the 4th hinge, 10, Γ shape connecting rod, 11, fixed mount, 12, microswitch, 13, spring
Embodiment
The present invention is further illustrated below in conjunction with drawings and embodiments.
As shown in Figure 1, the present invention has elastic component 2 at probe 1 outside cover, and flexible member 2 is with protective cover 3, and like this, before probe 1 soon bumped against object, protective cover 3 bumped against earlier, and flexible member 2 is resilient, therefore can not injure probe; Protective cover 3 is connected with an end of first connecting rod 6 by first hinge 4, and the centre of first connecting rod 6 is connected with fixed mount 11 by second hinge 5, so protective cover 3 can drive first connecting rod 6 around 5 rotations of second hinge; The other end of first connecting rod 6 is connected with an end of second connecting rod 8 by the 3rd hinge 7, the other end of second connecting rod 8 is connected with an end of Γ shape connecting rod 10 by the 4th hinge 9, the middle part of Γ shape connecting rod 10 is enclosed within on the fixed mount 11, and the rotation of first connecting rod 6 can drive Γ shape connecting rod 10 and do upper and lower moving in fixed mount 11; Γ shape connecting rod 10 is hung on the fixed mount 11 by spring 13 simultaneously, plays the effect of a string connecting rod of slinging; The below of Γ shape connecting rod 10 has a microswitch 12 to be installed on the fixed mount 11, Γ shape connecting rod 10 just can trigger microswitch 12 when having a trace to move down in fixed mount 11, thereby the circuit of the whole kinematic system of breaking, probe 1 is motion no longer, has protected probe 1; Fixed mount 11 is installed on the same parts with probe 1, and its maintenance is synchronized with the movement.
Described first hinge, 4 centers and second hinge, 5 centers are not positioned on the same perpendicular line; first hinge 4 be not arranged on second hinge 5 under; because if first hinge 4 be arranged on second hinge 5 under the time; when under the probe 1 foreign matter being arranged; when bumping against on the protective cover 3; be delivered on first hinge 4 power also to directly over; and first hinge 4 be arranged on second hinge 5 under; so just, can form one " dead point "; even strength is big again; also can not rotate first connecting rod 6, also just can't close whole kinematic system, with effective protection probe.
Flexible member 2 is flexible, and when protective cover 3 bumped against foreign matter, deformation can take place flexible member 2 like this, can be effectively to the buffer action of 1 formation of popping one's head in, and protection probe 1 is not subjected to serious bump effectively, and just protective cover 3 is clashed into.
As shown in Figure 2, microswitch 12 is connected with kinetic control system, and microswitch 12 is normally closed, and when Γ shape connecting rod 10 was run into microswitch 12, microswitch 12 disconnected, and whole kinetic control system circuit disconnects, 1 stop motion of popping one's head in.The control circuit that the kinetic control system circuit is used for existing lathe.
Testing process of the present invention is:
1, when protective cover 3 bumps against foreign matter, deformation takes place in flexible member 2, to the 1 not influence of popping one's head in.
2, owing to clashed into, the position of first hinge 4 can change.
Rotate around second hinge 5 thereby 3 drive first connecting rod 6, the 3rd hinge 7 that is fixed on the first connecting rod 6 also rotates.
4, drive second connecting rod 8 and rotate, and the 4th hinge 9 moves down around the 4th hinge 9.
5, the 4th hinge 9 drive Γ shape connecting rods 10 move down in fixed mount 11.
6, Γ shape connecting rod 10 moves down and touches microswitch 12, and the kinetic control system circuit disconnects.
