Detailed Description
The utility model will now be further described with reference to the accompanying drawings. Referring to fig. 1-3, fig. 1-3 illustrate one embodiment of the present utility model; the base plate, rotating shaft, and slew bearing shown in the figures are illustrative and the mechanism of this embodiment is adaptable to, but not limited to, the current installation and use environment.
The rotating equipment (machine tool) is provided with a rotating mechanism, the rotating mechanism comprises a fixed part and a rotating part, and the rotating part is in rotary connection with the fixed part through a rotating shaft and a rotary bearing (divided into an outer ring and an inner ring).
Referring to fig. 1, this embodiment is composed of two parts: the detection plate 1, the detection plate 1 is connected with the bottom plate of the fixed part of the rotary equipment. And a distance detecting device 2, wherein the distance detecting device 2 is connected with the side wall of the rotating shaft of the rotating piece of the rotating equipment.
Wherein, the bottom plate of the fixing piece is connected with the detection plate 1 and is fixed on the outer side of the slewing bearing; the rotating shaft and the detecting plate 1 are coaxially arranged, and the angle of the equipment after rotation can be mapped through the distance fed back by the detecting plate 1.
Referring to fig. 2, centrally located is a complete sensing plate 1, the sensing plate 1 being secured to the side of the stationary member facing the rotatable member by two connecting plates 11. The number and position of the connection plates 11 can be specifically adjusted as required. In this embodiment, the detection plate 1 is composed of four consecutive feedback panels connected end to end, circumferentially arranged around the rotation axis, each of the feedback panels covering a position corresponding to the angle to be measured. The feedback panels can form a complete circular ring and can be arranged at a position with a specific angle; may or may not be concentric.
Specifically, 12 is a bottom plate of the detection plate main body, and is also a lowest first-stage feedback panel, 13 is a second-stage feedback panel, 14 is a third-stage feedback panel, and 15 is a fourth-stage feedback panel. The heights of the four feedback panels are set to be equal difference heights according to the actual installation space, so that a circular step plate is formed. Each feedback panel uniquely maps a corresponding rotational orientation/angle to a location at a different distance from the distance detector 2; that is, the direction accuracy requirement to be detected is divided into different sections (the rotation mechanism example in fig. 2 is 360 ° rotation, the detection of 4 directions is equal to 90 °, so the feedback panel is set to a four-section gradient).
Referring to fig. 3, there is shown a mounting assembly of the photoelectric switch 22 corresponding to the detection plate 1. Reference numeral 21 denotes a mounting plate, preferably a bent sheet metal member, for fixing the connection distance detector 2 to a side wall of the rotating shaft. Of course, different design forms of the mounting plate can be selected according to actual mounting conditions, so that the distance detector 2 can always vertically and downwardly detect the distance (namely, the direction facing the detection plate 1), and the rotation center and the detection plate 1 are coaxial.
The distance detector 2 mounted above by the mounting plate 21 detects in a vertically downward direction. The rotating shaft of the rotating piece drives the distance detector 2 to rotate along the circumferential direction when the equipment operates, the controller inquires a corresponding mapping relation input in advance according to the distance information fed back by the distance detector 2, and a feedback panel of which level the current distance detection point is located can be obtained, so that the range of the current rotating angle of the rotating equipment can be mapped, and the current actual rotating direction of the rotating equipment is obtained.
In the embodiment, the feedback panels with different heights connected with the fixing piece are used, and the rotation angle and the orientation of the rotating piece are determined through the detection output of the distance detector 2 fixed with the rotation shaft of the rotating piece on the detection plate 1.
The mechanism in the above embodiment can detect the rotational orientations in four directions. Further, the detection precision of the utility model can be adjusted according to the actual requirement, the step density of the detection plate 1 can be adjusted according to different step numbers, such as eight, thirty-six or more equally divided step plates are formed on the circumference of the detection plate 1, and the detection direction and the detection precision of the photoelectric switch 22 can be properly adjusted.
When the detection accuracy needs to be further improved, the number of the step-shaped feedback panels can be towards infinity, so that an inclined plane is formed, and finally a circular inclined plane is formed. At this time, the distance between each point of the feedback panel and the distance detector is accurately and uniquely mapped to the corresponding rotation angle.
The key point of the utility model is to convert the angle information of the rotating equipment into the height information for mapping, and in the specific operation, the complex angle detection is converted into the simple photoelectric distance detection, thereby realizing the high degree of freedom of the installation space, the detection precision and the detection range, and being suitable for the non-reciprocating rotating equipment.
The mechanism provided by the utility model has a simple structure, does not have a high-precision mechanical structure, and has lower requirement on the installation space. The anti-interference device has high durability and strong anti-interference capability, and can bear physical impact in a certain range and various interference brought by the environment, such as humid environment corrosion, extreme temperature, extreme air pressure change and the like.
The embodiments of the present utility model have been described above with reference to the accompanying drawings and examples, which are not to be construed as limiting the utility model, but rather as modifications, variations or adaptations thereof may be made by those skilled in the art within the scope of the appended claims.
