Description
Technical field
The present invention relates to digit ctrol machine tool field, more particularly to a kind of Digit Control Machine Tool is accurately positioned main axle structure.
Background technology
Main shaft is core component in Digit Control Machine Tool, and the precision and rotation halted state of main shaft are to determine the pass of machining accuracy
Key, it is exactly that rotation is driven by servomotor first to have individual main shaft, and master is controlled by controlling the fine rotational of servomotor
The rotation of axle, but main shaft mass ratio is larger, there is inertia when rotation, cannot often be accurately positioned stopping, also cannot be accurate
Monitor the rotation number of turns of main shaft, it is impossible to realize numerical control precise control.
The content of the invention
What the technical problems to be solved by the invention were to provide a kind of Digit Control Machine Tool is accurately positioned main axle structure, with real-time
Brake location structure, can realize being accurately positioned for main shaft, and the actual rotation of main shaft is monitored by magnet ring encoder, be tied with positioning
Structure is engaged the rotation precision for improving main shaft, so as to reach the purpose of high-precision indexing.
The technical solution adopted for the present invention to solve the technical problems is：There is provided a kind of Digit Control Machine Tool is accurately positioned main shaft
Structure, including main spindle box, main shaft and main shaft oil cylinder, one end of described main shaft are stretched out from main spindle box and are connected with main shaft oil cylinder,
Axle sleeve is installed on main shaft between described main shaft oil cylinder and main spindle box, stopping of radially arranging is installed on the outside of the axle sleeve
Car piece, the side of described main spindle box is provided with brake, and described brake block is extend into the brake, on described main shaft
It is also equipped with magnet ring encoder.
Preferably, be provided with synchronizing wheel on main shaft between described axle sleeve and main spindle box, on the synchronizing wheel and lathe
Servo main motor be connected.
Further, described brake is pneumatics disc brake.
Beneficial effect：Main axle structure is accurately positioned the present invention relates to a kind of Digit Control Machine Tool, with brake positioning knot in real time
Structure, can realize being accurately positioned for main shaft, and the actual rotation of main shaft is monitored by magnet ring encoder, be engaged with location structure and carried
The rotation precision of main shaft high, so as to reach the purpose of high-precision indexing.

Specific embodiment
With reference to specific embodiment, the present invention is expanded on further.It should be understood that these embodiments are merely to illustrate the present invention
Rather than limitation the scope of the present invention.In addition, it is to be understood that after the content for having read instruction of the present invention, people in the art
Member can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
Scope.
As Figure 1-3, embodiments of the present invention are related to a kind of main axle structure that is accurately positioned of Digit Control Machine Tool, including master
Axle box 5, main shaft 6 and main shaft oil cylinder 1, one end of described main shaft 6 are stretched out from main spindle box 5 and are connected with main shaft oil cylinder 1, described
Axle sleeve 2 is installed on main shaft 6 between main shaft oil cylinder 1 and main spindle box 5, the outside of the axle sleeve 2 is provided with stopping of radially arranging
Car piece 3, the side of described main spindle box 5 is provided with brake 7, and described brake block 3 is extend into the brake 7, described
Magnet ring encoder 8 is also equipped with main shaft 6.
Preferably, be provided with synchronizing wheel 4 on main shaft 6 between described axle sleeve 2 and main spindle box 5, the synchronizing wheel 4 and machine
Servo main motor on bed is connected.
Further, described brake 7 is pneumatics disc brake.
Synchronizing wheel on main shaft 6 passes through toothed belt transmission with the synchronizing wheel of servo main motor, is compiled in spindle motor
Code device is reacted rapidly after receiving system shutdown instruction, is accurately stopped by the position for originally setting；Installed in main spindle box
On brake 7 after the same time receives system brake instruction, the brake block 3 on main shaft is embraced immediately, eliminate
Spindle operation inertia serves the effect being accurately positioned moment.
Possess indexing function equipped with magnet ring encoder 8 in spindle servo electric machine, but produced by after Timing Belt, wheel transmission
Geometric error, this technology is to install magnet ring encoder 8 on main shaft to synchronously rotate with spindle, with the detection being fixed on main spindle box
Point uses laser transfer reading error value, magnet ring encoder, control system is then fed back to, by two tunnel pulse rounding errors
Value, so as to reach the purpose of high-precision indexing.
Brake block common used material is：40GMO, 16mnCr5 etc., by the Technologies for Heating Processing such as quenched, high-frequency induction hardening, table
Surface hardness requirement reaches HRC55~60, to ensure the stability of wear-resisting intensity and material.
The present invention has brake location structure in real time, can realize being accurately positioned for main shaft, is monitored by magnet ring encoder
The actual rotation of main shaft, the rotation precision for improving main shaft is engaged with location structure, so as to reach the purpose of high-precision indexing.
