Abstract
The utility model discloses the accurate stop mechanism of a kind of direct type main shaft, comprise shaft coupling, described shaft coupling is fixed on mandrel; wherein; also comprise inductance loop, described inductance loop is fixed on the main shaft fixation side of shaft coupling, also comprises the signal for detecting inductance loop and sends the sensor that standard stops signal.Described shaft coupling is fixed on mandrel by expansion sleeve, and inductance loop is screwed in the main shaft fixation side of shaft coupling.The accurate stop mechanism of the direct type main shaft that the utility model provides, when not changing main shaft profile on the whole, when Installing machine tool tool magazine coordinates tool magazine to position spindle rotor part, effectively can reduce the deviation that main shaft orientation occurs.
Description
Technical field
The utility model relates to a kind of lathe coordinates tool magazine to position spindle rotor mechanism when installing tool magazine, is specifically related to the accurate stop mechanism of a kind of direct type main shaft.
Background technology
Lathe needs when installing tool magazine to coordinate tool magazine to position spindle rotor part, to ensure that manipulator is each all at same position when capturing cutter.Generally all rely on the accurate stop mechanism on motor to position, such main shaft portion may save accurate stop device, can also save segment space simultaneously, make main axle structure more compact.But the problem of reality is that the accurate stop device of first motor is not necessarily reliable, secondly motor is transduceed on main shaft by shaft coupling, shaft coupling is divided into again three parts, a part is connected with motor by expansion sleeve, another part is connected with main shaft by expansion sleeve, two parts are linked together by resislient gear wheel again, by may deviation be there is in the conduction of these connectors and installation process, thus causing between the position location of motor and the physical location of main shaft sometimes and inconsistent, this makes main shaft orientation there will be certain deviation.
The utility model, for the above-mentioned problems in the prior art, proposes the accurate stop mechanism of a kind of direct type main shaft.
Utility model content
Technical problem to be solved in the utility model is to provide the accurate stop mechanism of a kind of direct type main shaft.
The accurate stop mechanism of the direct type main shaft that the utility model provides; its structure is: comprise shaft coupling; described shaft coupling is fixed on mandrel; wherein; also comprise inductance loop; described inductance loop is fixed on the main shaft fixation side of shaft coupling, also comprises the signal for detecting inductance loop and sends the sensor that standard stops signal.
The accurate stop mechanism of above-mentioned direct type main shaft, wherein, described shaft coupling is fixed on mandrel by expansion sleeve, and inductance loop is screwed in the main shaft fixation side of shaft coupling.
The accurate stop mechanism of above-mentioned direct type main shaft, wherein, also comprises packing ring, and described packing ring is fixed on screw hole.
The utility model has following beneficial effect relative to prior art: the accurate stop mechanism of the direct type main shaft that the utility model provides; when Installing machine tool tool magazine coordinates tool magazine to position spindle rotor part; the signaling point be fixed on the inductance loop of shaft coupling main shaft fixation side is detected by sensor; thus send standard and stop signal, the accumulated error in this process of spindle end of operated motor rotor, the motor side of shaft coupling, Elastic Teeth torus, shaft coupling can be got rid of.
Accompanying drawing explanation
The structural representation of the accurate stop mechanism of direct type main shaft that Fig. 1 provides for the utility model.
In figure:
1 shaft coupling 2 mandrel 3 screw
4 inductance loop 5 sensors
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model will be further described.
The accurate stop mechanism of the direct type main shaft that the utility model provides; comprise shaft coupling 1, described shaft coupling 1 is fixed on mandrel 2, also comprises inductance loop 4; described inductance loop 4 is fixed on the main shaft fixation side of shaft coupling 1, also comprises the signal for detecting inductance loop 4 and sends the sensor 5 that standard stops signal.Described shaft coupling 1 is fixed on mandrel 2 by expansion sleeve, and inductance loop 4 is fixed on the main shaft fixation side of shaft coupling 1 by screw 3.
In addition, also comprise packing ring, described packing ring is fixed on screw 3 hole.
The accurate stop mechanism of the direct type main shaft that the utility model provides; when Installing machine tool tool magazine coordinates tool magazine to position spindle rotor part; the signaling point be fixed on the inductance loop 4 of shaft coupling 1 main shaft fixation side is detected by sensor 5; thus send standard and stop signal, the accumulated error in this process of spindle end of operated motor rotor, the motor side of shaft coupling 1, Elastic Teeth torus, shaft coupling 1 can be got rid of.
In addition, utilize the original screw hole of shaft coupling 1, inductance loop 4 can do very little, and the quantity of inductance loop 4 can also increase when not changing original main axle structure, to meet the diversified demand of client.
Although the utility model discloses as above with preferred embodiment; so itself and be not used to limit the utility model; any those skilled in the art; not departing from spirit and scope of the present utility model; when doing a little amendment and perfect, therefore protection domain of the present utility model is when being as the criterion of defining with claims.
Claims (3)
