Abstract
The utility model discloses a built-in installation structure for the dynamic balance head of the main shaft of a high speed gear grinding machine, comprising a grinding wheel mandrel (1) and the dynamic balance head (2), wherein a dynamic balance mandrel (3) is fixedly installed in a center hole in the grinding wheel mandrel (1); and the dynamic balance head (2) is installed in the center hole in the dynamic balance mandrel (3). Due to the adoption of a built-in arrangement structure, the dynamic balance head can be effectively prevented from damage or corrosion, so that the dynamic balance effect of the main shaft is reliably ensured, and the dynamic balance grade of the main shaft is further improved. The structure is simple so as to be easy to execute. Moreover, a built-in AE (Acoustic Emission) sensor can accurately collect and capture the acoustic signal of the grinding wheel mandrel, so as to prevent distortion, resulting from the wrong collection of other signals, thereby being applicably popularized to the installation structures for the dynamic balance heads of various high speed grinding main shafts.
Description
Technical field
The present invention relates to a kind of high speed gear grinding machines parts, relate in particular to the built-in mounting structure of dynamic balancing head of high speed gear grinding machines main shaft.
Background technology
At present, the dynamic balancing head of high speed gear grinding machines main shaft is because structural limitations generally adopts the external arrangement, and it specifically is installed on connecing on the dish of emery wheel left and right side.Because dynamic balancing head is exposed to the outside, so just is easy to damaged or corrode, and then has a strong impact on the dynamic balancing effect of main shaft, causes the dynamic balancing poor effect of main shaft.In addition; AE sensor (being calibrate AE sensor) also adopts the external arrangement; So just make the AE sensor when gathering emery wheel axle acoustical signal, also be easy to mistake and gather other acoustical signal; Thereby make the distorted signals of collection, and the AE sensor that is exposed to the outside also exist damaged or corrode maybe, be badly in need of solving the problems of the technologies described above for this reason.
Summary of the invention
Technical problem to be solved by this invention is the built-in mounting structure of high speed gear grinding machines main shaft dynamic balancing head that provides a kind of dynamic balancing effective.
Technical scheme of the present invention is following: the built-in mounting structure of a kind of high speed gear grinding machines main shaft dynamic balancing head; Comprise emery wheel axle (1) and dynamic balancing head (2); It is characterized in that: fixed installation dynamic balancing axle (3) in the centre bore of said emery wheel axle (1), said dynamic balancing head (2) is installed in the centre bore of this dynamic balancing axle (3).
The present invention is adjusted into hollow shaft with emery wheel axle (1) by solid shafting on the basis of traditional structure structure, dynamic balancing axle (3) is installed in this emery wheel axle, and dynamic balancing head (2) is installed in the centre bore of dynamic balancing axle (3).Adopt above structure; The present invention is because dynamic balancing head (2) adopts built-in arrangement just can effectively avoid being damaged or corroding; Thereby reliably guarantee the dynamic balancing effect of main shaft, and then improve the dynamic balancing grade of main shaft, simple in structure; Easy to implement, be suitable for extending to the dynamic balancing head mounting structure of various high-speed grinding main shafts.
The centre bore of said dynamic balancing axle (3) is a shoulder hole left small and right large, and said dynamic balancing head (2) is installed in the right part of this dynamic balancing axle centre bore; Right aperture in said dynamic balancing axle (3) is connected with transition piece (4) through internal thread; Right part at transition piece is connected with lining (5) through external screw thread, and this lining is fixedly connected with the taper shank (1a) of said emery wheel axle (1) right part through the holding screw (6) that circumferentially is provided with.
Transition piece in the above structure on the one hand can be preferably to dynamic balancing head (2) axial limiting; Can make things convenient for again on the other hand, securely dynamic balancing axle (3) is fixedly mounted in the centre bore of emery wheel axle (1); And drive dynamic balancing axle (3) and follow emery wheel axle (1) and rotate together; Simple in structure, make easily, and dismounting is also very convenient when changing emery wheel.
Be integrated with AE sensor (7) in said dynamic balancing head (2) inside; The spiral cable of this AE sensor (7a) is located in the left part of said dynamic balancing axle (3) centre bore; And link to each other with signal receiver (8), this signal receiver (8) is through connecing the left aperture that dish (9) is fixed on dynamic balancing axle (3).Through AE sensor (7) being integrated in dynamic balancing head (2) inside, so just can more accurately gather, catch the acoustical signal of emery wheel axle, prevent to gather other signal distortions, and built-in AE sensor also can be avoided being damaged or corroding preferably because of mistake.
Beneficial effect: the present invention is because dynamic balancing head adopts built-in arrangement just can effectively avoid being damaged or corroding; Thereby reliably guarantee the dynamic balancing effect of main shaft, and then improve the dynamic balancing grade of main shaft, simple in structure; Easy to implement; And the acoustical signal of emery wheel axle can more accurately be gathered, caught to built-in AE sensor, prevents to gather other signal distortions because of mistake, is suitable for extending to the dynamic balancing head mounting structure of various high-speed grinding main shafts.
