Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to specific embodiments of the present invention and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The following describes in detail the technical solutions provided by the embodiments of the present invention with reference to the accompanying drawings.
The embodiment of the invention discloses a patrol robot which comprises a contact type induction probe assembly structure. Specifically, referring to fig. 1 to 3, the touch sensing probe assembly structure includes a fixing member 1, a probe assembly 2, a rotating assembly 3, and an elastic return member 4. The fixing member 1 may be formed by extending a housing of the inspection robot, or may be formed by a bracket. The probe assembly 2 may include a probe cover 20, a probe body 22, and a fixed mount 24. The probe body 22 is a main probing functional part of the probe assembly 2, the fixing mounting part 24 is used for fixing the probe body 22 and protecting the rear part of the probe assembly 2, and the probe cover 20 covers the front and the side surfaces of the probe body 22 and the fixing mounting part 24 and is used for protecting the front part of the probe body 22.
The rotating assembly 3 comprises a rotating connecting piece 30 and a fixed connecting piece 32, the fixed connecting piece 32 is fixed with the fixed piece 1, a containing cavity 300 is arranged on the rotating connecting piece 30, the containing cavity 300 is provided with a detecting opening 300a, the detecting opening 300a is provided with an axis, a is indicated by a in fig. 1 and 2, the rotating connecting piece 30 is connected with the fixed connecting piece 32 in a rotating mode, and the rotating connecting piece 30 can drive the detecting opening 300a to rotate together. In fig. 3, the axis of the post-rotation detection opening 300a is denoted by a2, the axis of the pre-rotation detection opening 300a is denoted by a1, and a non-zero angle can be formed between a1 and a2 by comparing the axis before rotation with the axis after rotation.
The probe assembly 2 is disposed within the receiving cavity 300, and the probe assembly 3 has a first position (see fig. 1) in which it protrudes through the probe opening 300a and a second position (see fig. 2) in which it is retracted into the receiving cavity 300 along the axis a relative to the first position, the probe assembly 2 being movable between the first position and the second position to extend and retract the probe assembly 2 relative to the probe opening 300 a.
The elastic return member 4 is also disposed in the accommodating chamber 300, and one end of the elastic return member 4 is fixed to the probe assembly 2, and the other end of the elastic return member 4 is fixed to the accommodating chamber 300. The resilient return 4 is capable of exerting a force on the probe assembly 2 urging it back to the first position when the probe assembly 2 is between the first and second positions or in the second position, i.e. when the probe assembly 2 is in an inwardly retracted state.
To enable smooth movement of the probe assembly 2 between the first and second positions, a sliding connection between the probe assembly 2 and the receiving cavity 300 is preferred. In particular, it is possible to provide a number of sliding grooves extending along the axis a of the detection opening in the housing chamber 300, while a slider is provided on the probe assembly 2, cooperating with the sliding grooves. Or the peripheral wall of the accommodating chamber 300 is finished smooth and flat and parallel to the axis a, and the probe assembly 2 is directly in sliding fit with the peripheral wall of the accommodating chamber 300.
In order to prevent the probe assembly 2 from continuing to extend beyond the first position and even directly out of the receiving cavity 300a through the detection opening 300a, the present embodiment further provides a blocking portion 300b within the receiving cavity 300, and simultaneously provides a blocking mating portion 26 on the probe assembly 2, where the blocking mating portion 26 may be provided on the probe cover 20 or the fixed mounting portion 24. When the probe assembly 2 is in the first position, the blocking portion 300b abuts against the blocking engagement portion 26 and prevents the probe assembly 2 from continuing to extend out of the probe opening 300a.
The blocking portion 300b may be in the form of a stopper, and a plurality of blocking portions may be disposed in the accommodating cavity 300 along the circumferential direction, or may be directly disposed in a ring around the detecting opening 300a, and the blocking mating portion 26 may be in the same annular structure as the blocking portion 300b, or may be in a manner that a plurality of small mating portions are circumferentially combined.
When the blocking portion 300b is provided in the accommodating chamber 300, it is difficult for the probe assembly 2 to be fitted into the interior of the accommodating chamber 300 through the probe opening 300a due to the blocking of the blocking portion 300b, and at this time, it may be necessary to manufacture the rotary joint 30 into several pieces and then splice-mold it by some means, for example. This approach may lead to a complicated structure and lower assembly efficiency.
For ease of assembly, as shown in fig. 1 and 2, the receiving chamber 300 may be disposed through the rotary connector 30 along the axis a, the probe assembly 2 and the elastic return member 4 may be placed from an end of the receiving chamber 300 facing away from the detection opening 300a, and then a support member 5 may be fixed to an end of the receiving chamber 300 facing away from the detection opening 300a, the elastic return member 4 being disposed between the probe assembly 2 and the support member 5, the elastic return member 4 being in a natural state or a compressed state when the probe assembly 2 is in the first position, that is, the elastic return member 4 being sandwiched between the probe assembly 2 and the elastic return member 4, and the elastic return member 4 being in a compressed state when the probe assembly 2 is in the inwardly retracted state, so that the elastic return member 4 can exert a force urging the probe assembly 2 to return to the first position.
The elastic return element 4 may be a spring, a shrapnel or other similar structures, and may also be an elastomer made of a high polymer material, such as rubber. The number of the elastic return pieces 4 is not particularly limited, and a single elastic return piece 4 with high elasticity may be used, or a plurality of elastic return pieces 4 with low elasticity may be used to form an array. The force provided by the resilient return member 4 is preferably uniformly applied to the probe assembly 2. The elastic return member 4 may be fixedly connected to both ends of the contacted member (the probe assembly 2 and the support member 5), or may be fixedly connected to only one end of the contacted member, or may be limited in position by only elastic force and frictional force without being fixedly connected when the elastic return member 4 is always in a large compressed state.
When the curved surface is detected, the inspection robot drives the contact type induction probe assembly structure to be integrally close to the curved surface 6, after the probe assembly 2 contacts with the curved surface 6, an interaction force is formed between the probe assembly 2 and the curved surface 6, and the interaction force can be decomposed into two component forces, wherein one component force extends along the axis and forces the probe assembly 2 to retract towards the inside of the accommodating cavity 300 along the axis, the other component force extends along the rotation circumferential direction of the rotating assembly 3 and forces the rotating connecting piece 30 and the fixed connecting piece 32 to rotate relatively along the direction b. The overall orientation of the probe opening 300a and the probe assembly 2 can be changed by rotation, so that the axis a2 after rotation can pass through the center of the curved surface. Because the probe assembly 2 and the elastic return piece 4 always rotate along with the rotating connecting piece 30, the acting force of the elastic return piece 4 always keeps consistent with the axis, and the probe assembly 2 can be clung to the curved surface 6 under the thrust of the elastic return piece 4, so that the measurement precision for the curved surface 6 is greatly improved, and the application environment of the contact type induction probe is enlarged.
In this embodiment, the rotary link 30 needs to be rotatable relative to the fixed link in at least one dimension perpendicular to the axis a, such as in a direction up and down the page as shown in fig. 3, or in a direction perpendicular to the page. However, for the grid, the surface to be inspected may extend horizontally, or may extend vertically or diagonally. However, if the rotary joint 30 can be rotated in only a single dimension, only one of them can be handled, and thus there is still a limitation.
It is preferred that the rotational coupling 30 and the fixed coupling 32 are simultaneously rotatable in two dimensions perpendicular to the axis a, i.e. along a sphere. Specifically, to achieve this, as shown in fig. 1 to 3, the rotary connecting member 30 of the present embodiment has a first connecting surface 30a and a second connecting surface 32a on the fixed connecting member 32, where the first connecting surface 30a and the second connecting surface 32a are all part of a complete spherical surface, the first connecting surface 30a and the second connecting surface 32a are cooperatively connected and have the same spherical center, and the rotary connecting member 30 and the fixed connecting member 32 can perform spherical rotation relative to the spherical center.
The first connecting surface 30a and the second connecting surface 32a can be directly attached together, so that the two can realize spherical rotation, and only the friction force is high. Friction may be reduced between the first connection surface 30a and the second connection surface 32a by filling with lubricating oil or by embedding balls or the like. Typically, the second connecting surface 32a faces the center of the sphere, and the first connecting surface 30a faces away from the center of the sphere, i.e. the rotating connecting member 30 is wrapped with the fixed connecting member 32. However, in some special cases, a structure in which the first connection surface 30a faces the center of the sphere and the second connection surface 32a faces away from the center of the sphere is adopted, and in this case, the first connection surface 30a wraps the second connection surface 32a in the spherical rotation structure portion, the fixing connection member 32 is connected with the fixing member 1 in a region other than the second connection surface 32a, and the rotation connection member 30 is also provided with the accommodating cavity 300 in a region other than the first connection surface 30a, which still can satisfy the requirement, but the structure is relatively complex.
In theory, the purpose of rotating the probe assembly 2 can be achieved by only installing the probe assembly 2 on the rotating connector 30 so that the probe assembly rotates along with the rotating connector 30, however, if the axis a of the detection opening 300a does not pass through the center of sphere, that is, the detection opening 300a is arranged at an eccentric position, the rotation angle of the probe assembly 2 is linked with the position (the height or the left and right) of the spherical surface, so that the adjustment and lamination process of the detection surface and the curved surface is complicated, and the lamination efficiency and the lamination effect of the inspection robot are reduced. The axis a of the detection opening 300a passes through the center of the sphere, so that the above problems can be effectively avoided. Therefore, in order for the inspection robot to efficiently perform posture adjustment of the probe assembly 2, the axis a of the probe opening 300a preferably passes through the center of the sphere.
According to the contact type induction probe assembly structure and the inspection robot provided by the embodiment of the invention, when the surface to be inspected is a curved surface, the contact type induction probe assembly structure and the inspection robot can still keep close fit with the surface to be inspected through the rotation of the probe assembly 2 and the thrust of the elastic return piece 4, so that the measurement precision for the curved surface can be greatly improved, and the application environment of the contact type induction probe is enlarged.
The foregoing embodiments of the present invention mainly describe differences between the embodiments, and as long as there is no contradiction between different optimization features of the embodiments, the embodiments may be combined to form a better embodiment, and in view of brevity of line text, no further description is provided herein.
The foregoing is merely exemplary of the present invention and is not intended to limit the present invention. Various modifications and variations of the present invention will be apparent to those skilled in the art. Any modification, equivalent replacement, improvement, etc. which come within the spirit and principles of the invention are to be included in the scope of the claims of the present invention.
