The spindle is arranged inside the outer casing through a first bearing and a second bearing, the stator component is arranged on the side wall of the inside of the outer casing and disposed in the middle of the outer casing, the permanent magnet rotor component is mounted on the spindle, the front end cap is mounted at the front end of the outer casing, the rear end cap is mounted at the rear end of the outer casing, the encoder is mounted at the rear end of the spindle, the encoder is connected with an external driver, the spindle extends out of the front end cap, a grinding wheel head is arranged on the extension of the spindle, and the length of the grinding wheel head is a half of the extension of the spindle. The built-in grinding wheel spindle motor is small in size, the rotation angle of the grinding wheel head is expanded, and the application range of the surface grinding machine is widened.
Description
Technical field
The utility model relates to a kind of spindle motor, the built-in grinding wheel spindle motor of particularly a kind of surface grinding machine.
Background technology
The traditional type of drive of surface grinding machine grinding wheel spindle has two kinds, the one, motor output shaft drives the rotation of belt drives grinding machine spindle by belt pulley, this system configuration complexity, the bistrique gyration that is unfavorable for grinding machine, the loss in efficiency that belt transmission is also certain, and belt transmission is skidded easily, can not guarantee accurate gearratio.Another is that rearmounted asynchronous motor directly drives, and asynchronous motor exists volume big, the defective that power density is little.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, provides a kind of surface grinding machine built-in grinding wheel spindle motor.Volume of the present utility model is little, and has enlarged the bistrique angle range, has promoted the application surface of surface grinding machine.
For achieving the above object, the technical solution adopted in the utility model is: the built-in grinding wheel spindle motor of a kind of surface grinding machine, it is characterized in that: comprise shell, main shaft, the p-m rotor assembly, stator module, encoder, front end housing and rear end cap, described main shaft is arranged on enclosure by bearing one and bearing two, described stator module is arranged on the enclosure sidewall and is positioned at the centre position of described shell, described p-m rotor assembly is installed on the main shaft, described front end housing is installed in the front end of shell, described rear end cap is installed in the rear end of shell, rear end and described encoder that described encoder is installed in main shaft are connected with external driver, described main shaft stretches out from front end housing, and the extension of main shaft is provided with the emery wheel bistrique, and described emery wheel bistrique accounts for half of length of main shaft extension.
The built-in grinding wheel spindle motor of above-mentioned a kind of surface grinding machine, described front end housing and rear end cap are installed on the shell by screw one and screw two respectively.
The built-in grinding wheel spindle motor of above-mentioned a kind of surface grinding machine, described emery wheel bistrique is installed on the main shaft by nut.
The utility model compared with prior art has the following advantages: volume of the present utility model is little, and has enlarged the bistrique angle range, has promoted the application surface of surface grinding machine, its system configuration compactness, simple.This spindle motor power density is much larger than asynchronous motor, and the grinding machine head stock support body is long-pending obviously to be reduced.The easier expansion bistrique of this structure angle range, the application surface of lifting surface grinding machine.Described front end housing and rear end cap are installed on the shell by screw one and screw two respectively, make front end housing tightr with being connected of shell with rear end cap, have improved the resistance to overturning of the built-in grinding wheel spindle motor of a kind of surface grinding machine described in the utility model.Described emery wheel bistrique is installed on the main shaft by nut, makes the installation of emery wheel bistrique more fastening, thereby avoids occurring in the course of the work the phenomenon generation initiation security incident that the emery wheel bistrique breaks away from.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.

Embodiment
The built-in grinding wheel spindle motor of a kind of surface grinding machine as shown in Figure 1, comprise shell 3, main shaft 10, p-m rotor assembly 6, stator module 5, encoder 8, front end housing 2 and rear end cap 9, described main shaft 10 is arranged on shell 3 inside by bearing 1 and bearing 27, described stator module 5 is arranged on shell 3 internal side wall and is positioned at the centre position of described shell 3, described p-m rotor assembly 6 is installed on the main shaft 10, described front end housing 2 is installed in the front end of shell 3, described rear end cap 9 is installed in the rear end of shell 3, rear end and described encoder 8 that described encoder 8 is installed in main shaft 10 are connected with external driver, described main shaft 10 stretches out from front end housing 2, and the extension of main shaft 10 is provided with emery wheel bistrique 11, and described emery wheel bistrique 11 accounts for half of length of main shaft 10 extensions.Described front end housing 2 and rear end cap 9 are installed on the shell 3 by screw 1 and screw 2 12 respectively.Described emery wheel bistrique 11 is installed on the main shaft 10 by nut 13.
The built-in grinding wheel spindle motor of a kind of surface grinding machine described in the utility model, its system configuration compactness, simple.This spindle motor power density is much larger than asynchronous motor, and the grinding machine head stock support body is long-pending obviously to be reduced.The easier expansion bistrique of this structure angle range, the application surface of lifting surface grinding machine.Described emery wheel bistrique 11 accounts for half of length of main shaft 10 extensions, under the situation that the operate as normal that does not influence emery wheel bistrique 11 requires, has guaranteed the steadiness that emery wheel bistrique 11 is installed again, has improved the fail safe that emery wheel bistrique 11 uses.Described front end housing 2 and rear end cap 9 are installed on the shell 3 by screw 1 and screw 2 12 respectively, make front end housing 2 more fastening with being connected of shell 3, improved the resistance to overturning of the built-in grinding wheel spindle motor of a kind of surface grinding machine described in the utility model with rear end cap 9.Described emery wheel bistrique 11 is installed on the main shaft 10 by nut 13, makes the installation of emery wheel bistrique 11 more fastening, thereby avoids occurring in the course of the work the phenomenon generation initiation security incident that emery wheel bistrique 11 breaks away from.
