Description
Technical field
The utility model belongs to machine tool chief axis detection technique field, is specifically related to machine tool chief axis real-time measurement apparatus.
Background technology
The basis that Digit Control Machine Tool manufactures as industrial equipment, occupies very important status in national economy, present Digit Control Machine Tool toward high accuracy, high efficiency, high-revolving future development.The core component that machine tool chief axis is participated in directly as machine tooling, decides the machining accuracy of lathe, the performance parameters such as service life.How ensureing that lathe is in a healthy duty, is the inevitable technical barriers of Machine Tool design personnel.Wherein, what first will solve is exactly how to obtain various performance parameters when machine tool chief axis works, such as operating temperature, radial amplitude, axial float and heat distortion amount etc.
Chinese patent document CN 201993620 discloses a kind of numerical control machining tool heat error measuring machine tool chief axis and measures integrated system, this integrated measurement system can be measured the temperature of machine tool chief axis and heat distortion amount and can compensate, simply easy to operate, require to support to the technical capability of user.But this measuring system needs to measure when lathe stops, can not again machine tooling time measure in real time, the measurement data of gained is accurately not prompt enough, can not carry out on-line monitoring to machine tool chief axis health status.
Utility model content
Adding the temperature in man-hour to measure machine tool chief axis in real time, the parameters such as radial amplitude and axial float, the utility model provides a kind of machine tool chief axis real-time measurement apparatus.
A kind of machine tool chief axis real-time measurement apparatus, include in inductive displacement transducer, temperature sensor, acceleration transducer and bidirectional propulsion angle bearing, in displacement sensor, temperature sensor and acceleration transducer, be integrated with the bluetooth dispensing device that transmission detects data, interior installing ring is arranged on the inner underside face of bidirectional propulsion angle bearing outer ring and forms abutting relation with the left inside circle of bidirectional propulsion angle bearing and right inside circle of bidirectional propulsion angle bearing; Outer installing ring is arranged on the interior upper side of bidirectional propulsion angle bearing outer ring and forms abutting relation with the left inside circle of bidirectional propulsion angle bearing and right inside circle of bidirectional propulsion angle bearing; Four grooves being circumferentially used for installing inductive displacement transducer and temperature sensor are provided with at interior installing ring outer surface, be that interval is arranged alternately at interior installing ring outer surface inductive displacement transducer and temperature sensor, installing ring two sides are all arranged with the groove for installing acceleration transducer outside.
Preferably, four groove sizes on described interior installing ring are identical, to improve interior installing ring interchangeability and to reduce manufacturing cost.
Preferably, four groove sizes on described outer installing ring are identical, to improve outer installing ring interchangeability and to reduce manufacturing cost.
Preferably, the thickness of described interior installing ring and described outer installing ring is limited to 4-8mm.
The beneficial effect of a kind of machine tool chief axis real-time measurement apparatus of the utility model is, can again lathe work time realize on-line monitoring to machine tool chief axis.Inductive displacement transducer, temperature sensor and acceleration transducer can by the temperature of machine tool chief axis, and radial amplitude and axial movement value are measured in real time and be reacted to operator, allow operator know the health status of machine tool chief axis, to avoid processing defect ware.The utility model adopts the design of inside and outside installing ring, fixes within the bearing compactly, principal spindle of machine tool general layout can not be made to change, and reduces the impact on its processing, assembling.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further details.
As shown in Figure 1, interior installing ring 3 and outer installing ring 4 is provided with in bidirectional propulsion angle bearing, interior installing ring 3 and outer installing ring 4 respectively with bidirectional propulsion angle bearing outer ring 1, bidirectional propulsion angle bearing left inside circle 2a and bidirectional propulsion angle bearing right inside circle 2b against, specifically, interior installing ring 3 is arranged on the inner underside face of bidirectional propulsion angle bearing outer ring and forms abutting relation with the left inside 2a of circle of bidirectional propulsion angle bearing and the right inside 2b of circle of bidirectional propulsion angle bearing.Outer installing ring 4 is arranged on the interior upper side of bidirectional propulsion angle bearing outer ring and forms abutting relation with the left inside 2a of circle of bidirectional propulsion angle bearing and the right inside 2b of circle of bidirectional propulsion angle bearing.This arrangement makes compact overall structure stablize.See accompanying drawing 2 and accompanying drawing 3, the structure of interior installing ring 3 and outer installing ring 4 can be better understood, interior installing ring 3 has circumferential four grooves at outer surface, be used for inductive displacement transducer and temperature sensor (not shown) are installed, in order to stablize and measure machine tool chief axis 6 temperature and radial amplitude exactly, can be that interval is arranged alternately by inductive displacement transducer and temperature sensor.Certainly, 6 or 8 also can be set according to actual conditions inductive displacement transducer and temperature sensor, even more.Outer installing ring 4 two sides are all arranged with the groove for installing acceleration transducer (not shown), for detecting the axial float of machine tool chief axis 6.To improve outer installing ring interchangeability and to reduce manufacturing cost, interior installing ring 3 is identical with the groove size of outer installing ring 4, thickness for described interior installing ring 3 and outer installing ring 4 is selected, through test of many times and improvement, the utility model is limited in 4-8mm, and this is compromised by intensity own and the installation dimension of interior installing ring 3 and outer installing ring 4.In order to obtain the detection data of machine tool chief axis 6, be integrated with bluetooth dispensing device in the sensor, corresponding bluetooth receiving device is set at receiving terminal.This wireless transmission, is disclosed in this area, and such as Authorization Notice No. is state's patent of CN202025214 U, does not repeat them here.
