2. Description of the Related Art A motor having a built-in electric motor and performing horizontal rotation and vertical rotation of an internal movable portion by electric driving has been widely used. In such a surveying instrument, there is a problem that the initial torque when the built-in motor is driven is large, and the surveying instrument rotates against the spring force due to a reaction during the driving, and the above-described displacement occurs. The present invention has been made in view of the above circumstances, and aims to secure the fixing between the surveying instrument and the detachable table, and to prevent the displacement of the surveying instrument due to the initial torque or the like when the electric motor is driven. According to the present invention, there is provided a detachable table having a fitting portion to which an engaging portion of a surveying instrument can be fitted, and a base connected to the detachable table via a leveling screw. A table, and the detachable table has a rotatable wedge piece and a central part of the fitting part.
With a lock member that can advance and retreat to a position offset from
The wedge piece can be disengaged from an engagement groove provided on the surveying instrument side,
The lock member is offset to an engagement portion of the surveying instrument .
It relates to a detachable base of a surveying instrument that can be brought into contact at a position . In order to attach the surveying instrument to the detachable base, the engaging portion of the surveying instrument is fitted to the fitting portion, the wedge piece is rotated to engage the engaging groove, and the lock member is further operated. Then, the locking member is pressed against the engaging portion to lock. An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is a surveying instrument, 2 is a detachable table, 3 is a base, and 4 is a leveling screw. A fitting recess 5 is provided at the center of the detachable table 2, and an engaging hole 21 is formed at a bottom portion of the fitting recess 5 at a position equally divided into three in the circumferential direction. A rotating plate 6 is rotatably provided on the bottom surface of the fitting recess 5, and a wedge piece 7 is projected from the rotating plate 6 at a position equally divided into three in the circumferential direction. The wedge piece 7 is tapered in two directions, a radial direction and a circumferential direction. The rotary plate 6 is provided with a slide pin 8 slidable in a tangential direction of a circle centered on the rotation axis of the rotary plate 6, and the slide pin 8 is retracted by a spring 9 (FIG. 2). (Middle upper right). A piece receiving piece 10 is fixed to the projecting end of the slide pin 8. A detachable knob 11 is rotatably provided on a side surface of the detachable table 2, and a detachable lever 12 is fitted to a protruding end of a rotating shaft of the detachable knob 11. A piece 13 that can contact the piece receiving piece 10 is rotatably provided. Further, a bolt holder 1 is provided on a side surface of the attaching / detaching table 2.
4 is fitted, and the lock bolt 1 is
5 is screwed into the lock bolt 15, an inner end of the lock bolt 15 can protrude from an inner wall of the fitting recess 5, and a lock knob 16 is fixed to an outer end. The axis of the lock bolt 15 is offset from the center of rotation of the rotary plate 6 by a required distance. On the lower surface of the surveying instrument 1, a short cylindrical engaging portion 17 is provided. The engaging hole 2 is provided on the lower surface of the engaging portion 17.
The three protruding pieces 18 to be fitted into 1 are protruded. An engagement groove 19 that can be engaged with the wedge piece 7 is formed inside the projection piece 18. Further, a flat surface 20 is formed at an offset position of the cylindrical surface of the engaging portion 17. The position of the flat surface 20 corresponds to the lock knob 16. The attachment and detachment of the surveying instrument 1 to and from the attachment table 2 will be described below. The lock bolt 15 has its inner end retracted from the inner wall of the fitting recess 5. The piece receiving piece 10 is attached to the piece 13 and the flat surface 20 is attached to the lock bolt 15.
The engaging portion 17 is fitted into the fitting concave portion 5 while the protruding piece 18 is fitted into the rotating plate 6. Next, the attachment / detachment knob 11 is rotated, and the wedge piece 7 is rotated counterclockwise in FIG. To be engaged. Since the engaging portion 17 has a tapered shape in the two directions of the radial direction and the circumferential direction as described above, the wedge piece 7 and the projecting piece 18 are engaged without rattling by the wedge effect. Since the rotational force of the detachable knob 11 is transmitted to the rotary plate 6 via the piece receiving piece 10, the slide pin 8, and the spring 9, the repulsive force of the spring 9 causes the wedge piece 7 and the projecting piece to move in the initial state. 1
8 engage. Further, the lock knob 16 is rotated, the lock bolt 15 is pushed in, and the tip of the lock bolt 15 is pressed against the flat surface 20. By tightening the lock bolt 15, the surveying instrument 1 is securely fixed to the detachable table 2. or,
Since the lock bolt 15 is offset as described above, the surveying instrument 1 is fixed by the rotation force in the same direction as the rotation direction given by the rotating plate 6 by tightening the lock bolt, and rattling is completely suppressed. Since the surveying instrument 1 is mechanically fixed without the elastic body being interposed in the detachable table 2, the surveying instrument 1 may be displaced from the detachable table 2 even by the reaction force when the electric motor is driven. Will not wake up. Various changes can be made without departing from the gist of the present invention, such as using a V groove instead of the flat surface 20, or not offsetting the lock bolt 15, and using a push rod or the like instead of the lock bolt. It goes without saying that it can be added. As described above, according to the present invention, the surveying instrument and the detachable table can be securely fixed with a simple mechanism, horizontal rotation caused by rattling can be suppressed, and the horizontal angle at the time of measurement can be suppressed. Various excellent effects such as prevention of occurrence of errors, improvement of measurement accuracy, and high accuracy of reproduction at the time of attachment / detachment can be achieved.
