Detailed Description
The following non-limiting detailed description of the present invention is provided in connection with the preferred embodiments and accompanying drawings.
As shown in fig. 1 and 2, the angle measuring mechanism for table top of operating bed according to a preferred embodiment of the present invention includes a fixing frame 13 fixed on the frame 10, a potentiometer 14 installed on the fixing frame 13, a clamping block 15 for clamping the measuring shaft 140 of the potentiometer 14, and a bracket 16 fixed on the column 1.
The fixing frame 13 is connected to the frame 10 by the first bolt 17, and the measuring shaft 140 of the potentiometer 14 passes through the fixing frame 13 and is fixed on the fixing frame 13 by the nut 18. When the potentiometer 14 is mounted on the fixing frame 13, the measuring shaft 140 is coaxially arranged with the rotating shaft 11.
The bracket 16 is connected to the upright post 1 through a second bolt 18, and the bracket 16 is provided with a through hole 160 for the clamping block 15 to pass through. One end of the clamping block 15 is clamped on the measuring shaft 140, and the other end is inserted into the through hole 160.
As shown in fig. 3 and 4, the clamp block 15 includes a base 20, and a first clamp arm 21 and a second clamp arm 22 connected to the base 20, and the first clamp arm 21 and the second clamp arm 22 are separated by a gap 23. A clamping hole 24 matched with the measuring shaft 140 is formed at the end of the first and second clamping arms 21 and 22.
The first clamping arm 21 is provided with a through hole 25, the second clamping arm 22 is provided with a threaded hole 26 communicated with the through hole 25, the clamping bolt 27 penetrates through the through hole 25 to be connected with the threaded hole 26, and the first clamping arm 21 and the second clamping arm 22 can be driven to approach each other by screwing the clamping bolt 27, so that the measuring shaft 140 positioned in the clamping hole 24 is clamped.
The shape of the through hole 160 is identical to the shape of the base 20, and in the present embodiment, the cross-sectional shape of the base 20 is rectangular, and the shape of the corresponding through hole 160 is also rectangular.
When the frame 10 and the upright post 1 rotate relatively, the clamping block 15 clamps the measuring shaft 140 to rotate, so that the potential in the potentiometer 14 changes, and angle data can be converted according to the potential change, thereby realizing angle measurement.
Because the clamping block 15 is inserted into the through hole 160, the clamping block 15 cannot be completely attached to the through hole 160 due to reasons such as machining precision, and a certain gap is generated between the clamping block 15 and the through hole 160, so that an angle difference exists between an actually generated rotation angle of the frame 10 and a rotation angle of the potentiometer measuring shaft 140, and the potentiometer 14 cannot accurately measure the inclination angle of the table top.
To this end, the utility model provides a following scheme solves this problem: as shown in fig. 4, the base 20 has a first surface 20a and a second surface 20b on both sides thereof, the first surface 20a being opposite to the second inner side 162 of the through hole 160, and the second surface 20b being opposite to the first inner side 161 of the through hole 160. A slide groove 28 is formed in the first surface 20a, a slider 30 is provided in the slide groove 28, the slider 30 is movable in the slide groove 28, and a driving member 31 for driving the slider 30 to extend out of the slide groove 28 is connected to the base portion 20. Specifically, the second surface 20b is provided with a screw hole 29 communicating with the slide groove 28, and a driving member 31 is screwed into the screw hole 29, preferably, a jack screw. After the top screw is rotated, the slide groove 28 is extended out of the slide groove 28 to abut against the first inner side edge 161 of the through hole 160. When the top thread presses the sliding groove 30 against the first inner side 161, the gap between the two sides of the clamping block 15 and the through hole 160 will be eliminated (refer to fig. 5). The rotation angle of the potentiometer measuring shaft 140 will be synchronized with the rotation angle of the frame 10 so that the potentiometer 14 can accurately measure the angle of mutual rotation of the frame 10 and the column 1.
It will be appreciated that the drive member may be other threaded components, such as a bolt.
The utility model discloses an operation table mesa angle measurement mechanism simple structure, simple to operate, and can support the measuring frame and the stand rotation angle that tight through-hole side slider makes the potentiometer can be accurate through the setting.
It should be noted that the above-mentioned preferred embodiments are only for illustrating the technical concepts and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention accordingly, and the protection scope of the present invention cannot be limited thereby. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
