Probe assembly 2 is arranged in accommodating chamber 300, and probe assembly 3 has the first position (ginseng for stretching out detection opening 300a See Fig. 1) and relative to the second position (referring to fig. 2) that first position is retracted along axis a into detection cavity 300, probe group Part 2 can move between first position and the second position, keep probe assembly 2 flexible relative to detection opening 300a.
Elastic recoil part 4 is also disposed in accommodating chamber 300, and one end of elastic recoil part 4 and probe assembly 2 keep solid Fixed, the other end and the accommodating chamber 300 of elastic recoil part 4 are kept fixed.When probe assembly 2 be in first position and the second position it Between or be in the second position when, that is, when probe assembly 2 be in inwardly retract state when, elastic recoil part 4 can Apply the active force for promoting to return it to first position to probe assembly 2.
In order to enable probe assembly 2 smoothly to move between the first location and the second location, probe assembly 2 and receiving It is preferably slidably connected between chamber 300.Specifically, it can be arranged what several axis a along detection opening extended in accommodating chamber 300 Sliding slot, while the sliding block cooperated with sliding slot is set on probe assembly 2.Or the peripheral wall of accommodating chamber 300 is arranged smooth flat Whole and be parallel to axis a, peripheral wall of the probe assembly 2 directly with accommodating chamber 300 is slidably matched.
Probe assembly 2 continues to stretch out after crossing first position in order to prevent, or even is directly detached from and is held by detection opening 300a Receive chamber 300a, the present embodiment is also provided with blocking portion 300b in accommodating chamber 300, while blocking is provided on probe assembly 2 Auxiliary section 26 stops auxiliary section 26 to can be set on probe cover 20 or fixed installation portion 24.When probe assembly 2 is in described When first position, blocking portion 300b offsets with auxiliary section 26 is stopped, and probe assembly 2 is prevented to continue to stretch out detection opening 300a.
Blocking portion 300b can use block form, several circumferentially be arranged in accommodating chamber 300, or can also be straight It connects in a ring around one circle of detection opening 300a setting, stops auxiliary section 26 that can use ring junction as blocking portion 300b Structure, can also be in such a way that multiple small auxiliary sections circumferentially surround combination.
When being provided with blocking portion 300b in accommodating chamber 300, due to the blocking of blocking portion 300b, probe assembly 2 be difficult by Detection opening 300a is packed into the inside of accommodating chamber 300, may need to make by some means, such as by rotating connector 30 at this time It is made several valves then spicing forming type.And this mode will lead to that structure is complicated and change, and reduce assembly efficiency.
For the ease of assembly, as depicted in figs. 1 and 2, the present embodiment can set accommodating chamber 300 to penetrating through along axis a Rotating connector 30, probe assembly 2 and elastic recoil part 4 can be by accommodating chambers 300 away from one end quilt of detection opening 300a It is put into, fixes a supporting element 5 away from one end of detection opening 300a in accommodating chamber 300 later, elastic recoil part 4, which is in, to be visited Between head assembly 2 and supporting element 5, when probe assembly 2 is in first position, elastic recoil part 4 in the raw or compression State, that is to say, that elastic recoil part 4 is clipped in the middle by probe assembly 2 and elastic recoil part 4, when probe assembly 2 is in inside When the state of retraction, elastic recoil part 4 is in compressive state, therefore elastic recoil part 4 can promote it to the application of probe assembly 2 Return to the active force of first position.
Elastic recoil part 4 can use spring, elastic slice or other similar structures, can also be using made of high molecular material Elastomer, such as rubber.The quantity of elastic recoil part 4 is not particularly limited, and can use the elastic recoil part of single high-tension 4, array can also be formed using the elastic recoil part 4 of multiple low elastic force.Active force provided by elastic recoil part 4 is preferably able to Uniformly it is applied on probe assembly 2.Also, elastic recoil part 4 can by both ends simultaneously with the component (probe assembly 2 that is contacted And supporting element 5) be fixedly connected, only wherein one end can also be fixedly connected with the component contacted, begun in elastic recoil part 4 When being in biggish squeezed state eventually, it is also contemplated that only relying on elastic force and frictional force without being fixedly connected to limit elasticity The position of return member 4.
When detecting to curved surface, it is whole close to curved surface that crusing robot will drive contact inductive probe assembling structure 6, after probe assembly 2 is contacted with curved surface 6, it will form interaction force between probe assembly 2 and curved surface 6, this strand of active force can be with Two stock power are broken down into, wherein one component extends along axis, and forces probe assembly 2 along axis to inside accommodating chamber 300 It retracts, another stock power is circumferentially extended along the rotation of runner assembly 3, and forces rotating connector 30 and fixedly connected part 32 along b Direction relatively rotates.The whole direction of detection opening 300a and probe assembly 2 can be changed by rotating, to make to turn Axis a2 after dynamic can pass through the center of circle of curved surface.Since probe assembly 2 and elastic recoil part 4 follow rotating connector always 30 rotate together, therefore the active force of elastic recoil part 4 is also consistent with axis always, and probe assembly 2 is in elastic recoil part 4 Thrust under can be close to curved surface 6, therefore the measurement accuracy for curved surface 6 greatly improved, expands contact inductive probe Application environment.
In the present embodiment, rotating connector 30 be required at least one dimension perpendicular to axis a relative to Fixedly connected part rotates, such as the direction shown in Fig. 3 like that above and below paper is rotated, or along perpendicular to paper Direction is rotated.However, detected face may be along horizontal extension for power grid, it is also possible to along vertical or oblique prolong It stretches.And if rotating connector 30 can only be rotated in single dimension, it is merely able to deal with one of situation, therefore Still there is certain limitation.
So being preferably able between rotating connector 30 and fixedly connected part 32 simultaneously in two dimensions perpendicular to axis a It is interior while being rotated, that is, globally rotated.Specifically, in order to realize the purpose, as shown in Figure 1 to Figure 3, originally There is the first joint face 30a on rotating connector 30 in embodiment, while there is the second joint face in fixedly connected part 32 32a, the first joint face 30a and the second joint face 32a are a part of a complete spherical surface, the first joint face 30a with Second joint face 32a is cooperatively connected and the centre of sphere having the same, and rotating connector 30 and fixedly connected part 32 can be relative to balls The heart carries out spherical rotation.
First joint face 30a and the second joint face 32a can be directly fitted together, and spherical surface turn may be implemented in the two in this way Dynamic, only frictional force is larger.Can also between the first joint face 30a and the second joint face 32a by filling lubricating oil or The forms such as ball are inlayed to reduce frictional force.Under normal conditions, the second joint face 32a is towards the centre of sphere, and the first joint face 30a is then Rotating connector 30 is wrapped up backwards to the centre of sphere, that is, with fixedly connected part 32.However, in some special cases, can also adopt With the first joint face 30a towards the centre of sphere and the second joint face 32a backwards to the centre of sphere structure, at this point, in spherical rotation structure division It is that the first joint face 30a wraps up the second joint face 32a, region and fixation of the fixedly connected part 32 other than the second joint face 32a Part 1 is attached, and also accommodating chamber 300 is arranged in the region other than the first joint face 30a to rotating connector 30, and this structure is still It can satisfy requirement, only structure is complex.
Theoretically, as long as probe assembly 2 is mounted on rotating connector 30, make it with 30 turns of rotating connector It is dynamic, it can achieve the purpose that rotate probe assembly 2, however, if detecting the axis a of opening 300a and without the centre of sphere, also That will detect opening 300a setting in eccentric position, then the rotational angle of probe assembly 2 and its spherical surface position (height or Left and right) connection can be generated, test surface can be bonded to process complication with the adjustment of curved surface in this way, reduce the fitting of crusing robot Efficiency and fitting effect.And the axis a for detecting opening 300a then can effectively avoid the presence of the above problem by the centre of sphere.Cause This, in order to enable crusing robot efficiently to carry out pose adjustment to probe assembly 2, the axis a of detection opening 300a is best The centre of sphere can be passed through.
Contact inductive probe assembling structure and crusing robot provided by the embodiment of the present invention are song in detected face When face still the close patch with detected face can be kept by the thrust of the rotation of probe assembly 2 and elastic recoil part 4 It closes, the measurement accuracy for curved surface can be greatly improved, expand the application environment of contact inductive probe.
Emphasis describes the difference between each embodiment, difference between each embodiment in foregoing embodiments of the present invention As long as optimization feature non-contradiction, can combine to form more preferably embodiment, it is contemplated that style of writing is succinct, then no longer superfluous at this It states.
The above description is only an embodiment of the present invention, is not intended to restrict the invention.For those skilled in the art For, the invention may be variously modified and varied.All any modifications made within the spirit and principles of the present invention are equal Replacement, improvement etc., should be included within scope of the presently claimed invention.
