Abstract
The utility model discloses a turntable type locking device for locking a turntable shafting at any angle, which comprises a rotating table top, wherein a locking sleeve is arranged on the lower end surface of the rotating table top, a fixed base is arranged below the rotating table top, a locking frame arranged on the outer side of the locking sleeve is movably arranged on the fixed base through a pin shaft, a locking plate is arranged on the inner side of the locking sleeve, a locking support is further arranged on the fixed base, and a locking screw for locking and connecting the locking frame and the locking plate is arranged on the locking support. When the locking screw is loosened, the locking sleeve can rotate to any angle along with the rotary table surface, and when the locking screw is screwed down again, the locking frame and the locking plate clamp the locking sleeve, so that the rotary table surface and the rotary table shaft system thereof can be locked at any angle.
Description
Technical Field
The utility model relates to a turntable type locking device for locking a turntable shafting at any angle with high precision.
Background
At present, the shafting locking device with the locking function is suitable for calibration tests in certain scenes of the inertial navigation test turntable. In general, a locking device of a turntable can only lock at a set angle (such as 0 °, 90 °, 180 ° and 270 °) of a turntable shaft system, and when the locking device needs to lock at any angle, an electric locking mode is generally adopted, and the electric locking device generally comprises a worm gear. The traditional locking device is complex in structure, low in locking precision and low in locking load, and the requirement of high-precision locking of the high-precision testing turntable at any angle is difficult to meet.
Disclosure of utility model
The utility model aims to provide a turntable type locking device for locking a turntable shaft system at any angle so as to solve the problems in the prior art.
The technical scheme adopted for achieving the purpose is that the turntable type locking device for locking the turntable shafting at any angle comprises a rotary table top, wherein a locking sleeve is arranged on the lower end face of the rotary table top, a fixed base is arranged below the rotary table top, a locking frame arranged on the outer side of the locking sleeve is movably mounted on the fixed base through a pin shaft, a locking plate is arranged on the inner side of the locking sleeve, a locking support is further arranged on the fixed base, and a locking screw used for locking and connecting the locking frame and the locking plate is arranged on the locking support.
Further, the locking sleeve is of an annular structure, and is fixedly connected to the lower end face of the rotary table top and is connected with the rotary table top to form an integral structure.
Further, the contact surfaces between the locking sleeve and the locking frame and the locking plate are arc-shaped structures.
Advantageous effects
Compared with the prior art, the utility model has the following advantages.
1. When the locking screw is loosened, the locking sleeve can rotate to any angle along with the rotating table top, and after the locking screw is screwed down, the turntable shafting can be locked at any angle;
2. In the utility model, a relatively large friction force is generated among the locking sleeve, the locking frame and the locking plate, and the contact surfaces among the locking sleeve, the locking frame and the locking plate are arc-shaped, so that relatively large load generated by shaking of the turntable shafting can be borne, the turntable shafting can be locked at any angle with high precision, and the turntable shafting can be locked or unlocked only by simple control.
3. The locking device is connected to the fixed base, so that the original rotary table shafting layout is not disturbed.
Drawings
The present utility model is described in further detail below with reference to the accompanying drawings.
FIG. 1 is a front cross-sectional view of the structure of the present utility model;
The figure shows: 1-locking sleeve, 2-rotating table top, 3-locking screw, 4-locking support, 5-locking frame, 6-locking plate, 7-fixed base and 8-pin shaft.
Detailed Description
The present utility model will be described in further detail with reference to examples and drawings.
As shown in fig. 1, the turntable type locking device for locking the turntable shafting at any angle comprises a rotary table top 2, wherein a locking sleeve 1 is arranged on the lower end surface of the rotary table top 2, a fixed base 7 is arranged below the rotary table top 2, a locking frame 5 arranged on the outer side of the locking sleeve 1 is movably installed on the fixed base 7 through a pin shaft 8, a locking plate 6 is arranged on the inner side of the locking sleeve 1, a locking support 4 is further arranged on the fixed base 7, and a locking screw 3 used for locking and connecting the locking frame 5 and the locking plate 6 is arranged on the locking support 4.
The locking sleeve 1 is of an annular structure, and the locking sleeve 1 is fixedly connected to the lower end face of the rotary table top 2 and is connected with the rotary table top 2 into an integral structure.
The contact surfaces between the locking sleeve 1 and the locking frame 5 and the locking plate 6 are arc structures.
In the utility model, the locking screw 3 connects the locking plate 6 and the locking frame 5 together; when the locking screw 3 is loosened, the locking sleeve 1 rotates to any angle along with the rotary table top 2, and after the locking screw 3 is screwed, the rotary table shafting can be locked at any angle.
The locking sleeve 1 rotates along with the rotating table top 2, the locking sleeve 1 is positioned between the locking frame 5 and the locking plate 6, and the locking screw 3 connects the locking frame 5 and the locking plate 6 together; the locking frame 5 is connected to the fixed base 7 through a pin shaft 8, and a locking support 4 is arranged below the locking screw 3.
When the locking screw 3 is loosened, the locking sleeve 1 can rotate to any angle along with the rotary table top 2, and after the locking screw 3 is tightened again, the turntable shafting can be locked at any angle. The locking sleeve 1, the locking frame 5 and the locking plate 6 can generate larger friction force, and the contact surfaces between the locking sleeve 1, the locking frame 5 and the locking plate 6 are arc-shaped, so that larger load generated by shaking of the turntable shafting can be borne, and the turntable shafting can be locked at any angle with high precision. And the turntable shafting can be locked or unlocked by simple control. The locking device is connected to the fixed base through a pin shaft, so that the original rotary table shafting layout is not disturbed.
