Abstract
The utility model discloses a rotation joint's limit structure, including circuit board, circuit board protection architecture and rotor arm, the circuit board has one section circular arc with circuit board protection architecture's appearance profile, and this section circular arc is exactly rotation joint's home range, and in the playing the initial point and finish a little respectively to have a set of stop device of home range, stop device stops by a limit switch and machinery that the structure forms, and limiting blocking piece rotates when arriving limit point, can touch earlier limit switch touches mechanical stopping after, the utility model provides high rotation joint's security to stop device sets up on the same circumference of joint pivoted, produces and install more succinctly.
Description
Technical field
This utility model is related to motor mounting technique, more particularly, to a kind of position limiting structure of cradle head.
Background technology
Cradle head can cause to equipment to damage beyond safety range in the case of accident at present, and discrete spacing triggering fills
Put there is also and loaded down with trivial details, hardly possible of working in coordination problem is installed.
Utility model content
This utility model provides a kind of position limiting structure of cradle head, controls double limitation using physical barriers and circuit
Mode, improves safety, and produces and install more succinct.
A kind of position limiting structure of cradle head, including control board, described control board is provided with first spacing
Switch and the second limit switch, circuit protection structure is provided with the spacing mechanical stop of corresponding first and the second spacing machinery
Stop, described control board, circuit protection structure and cursor are combined together by center of rotation connection, described cursor
One spacing barrier sheet of upper setting, described cursor rotates in the range of the circular arc of described circuit protection structure gabarit.
Further, the starting point of described spacing catch and described circular arc and end point are located at same turning circumference.
Further, described first limit switch, the second limit switch, and corresponding first spacing mechanical stop and second
The position of spacing mechanical stop is adjustable, thus adjusting the slewing area of cursor.
This utility model passes through to be controlled with physical barriers and circuit, solves the problems, such as that cradle head exceeds safety range, knot
Structure is simple, improves the overall stability of motor and safety.
Brief description
Fig. 1 is structure composition schematic diagram of the present utility model；
Fig. 2 is the schematic diagram that in this utility model, cursor turns to the first limit point；
Fig. 3 is the schematic diagram that in this utility model, cursor turns to the second limit point.
Wherein, 1- control board, 2- first limit switch, the spacing mechanical stop of 3- first, 4- center of rotation, 5- second
Limit switch, the spacing catch of 6-, the spacing mechanical stop of 7- second, 8- cursor, 9- circuit protection structure.
Specific embodiment
A kind of position limiting structure of cradle head, as shown in figure 1, including control board 1, described control board 1 sets
It is equipped with the first limit switch 2 and the second limit switch 5, circuit protection structure 9 is provided with corresponding first spacing machinery resistance
Gear 3 and the second spacing mechanical stop 7, described control board 1, circuit protection structure 9 and cursor 8 pass through center of rotation 4
Knot is combined together, and described cursor 8 arranges a spacing catch 6, described cursor 8 is outside described circuit protection structure 9
Rotate in the range of wide circular arc.Cursor 8 rotates and reaches circular arc starting point or during end point, and spacing catch 6 can first touch the
One limit switch 2 or the second limit switch 5, after touch corresponding first mechanical stop 3 or the second mechanical stop 7.
Further, the starting point of described spacing catch 6 and described circular arc and end point are located at same turning circumference.
Further, described first limit switch 2, the second limit switch 5, and corresponding first spacing mechanical stop 3 He
The position of the second spacing mechanical stop 7 is adjustable, thus adjusting the slewing area of cursor 8.
Cursor 8 rotates counterclockwise to initial point position, as shown in Fig. 2 the spacing catch 6 on cursor 8 triggers first
First limit switch 2, control circuit 1 sends control signal order and rotates and stops because of the triggering of the first limit switch 2；Immediately
, spacing catch 6 is blocked by the first mechanical stop 3, mechanical arm 8 stops rotating counterclockwise.
Cursor 8 is rotated clockwise to end point position, as shown in figure 3, the spacing catch 6 on cursor 8 triggers first
Second limit switch 5, control circuit 1 sends control signal order and rotates and stops because of the triggering of the second limit switch 5；Immediately
, spacing catch 6 is blocked by the second mechanical stop 7, mechanical arm 8 stops rotating clockwise.
Above specific embodiment of the present utility model is described, but this utility model is not limited to above retouching
State.For a person skilled in the art, any equal modifications and substitutions to the technical program are all in this utility model
Scope among.Therefore, the impartial conversion made under without departing from spirit and scope of the present utility model and modification, all should cover
In the range of this utility model.
