In the end of secondary drive shaft.
The beneficial effects of the present invention are: the transmission shaft of traditional grinding attachment is divided into multistage, every segment length control compared with
In small range, multiple groups speed adjusting gear is configured, accelerates step by step, can guarantee that every section of transmission shaft is able to maintain stable operation in this way,
Speed control is preferable, and non-jitter, machining accuracy are higher in process for device.
Based on the above technical solution, the present invention can also be improved as follows.
Further, preferred 1:1.2~3 of the speed ratio of the coaxial speed reducer；The speed ratio of the coaxial speed reducer is optimal
Select 1:1.5~2.
Beneficial effect using above-mentioned further scheme is: can make whole device stable acceleration step by step, avoid list
Step velocity is too fast to be caused to shake, and influences machining accuracy.
Further, between the transmission shaft and grinding abrasive disk be configured with two-stage speed adjusting gear, transmission shaft by shaft coupling with
Coaxial speed reducer is connected, and the shaft coupling of the coaxial speed reducer other end then connects secondary drive shaft, and the secondary drive shaft is provided with
Two, one group of coaxial speed reducer is also connected between two secondary drive shafts and shaft coupling, grinding abrasive disk are fixedly connected on least significant end
Secondary drive shaft end.
Beneficial effect using above-mentioned further scheme is: after setting two-stage adjusts the speed, the working depth of whole device can be with
It is effectively promoted, theoretically most deep working depth can achieve 1800mm or more, and stable, non-jitter, processing
Precision is higher.
Further, the length of the transmission shaft preferably 50~80mm.
Using the beneficial effect of above-mentioned further scheme is: transmission shaft is in low-speed run state, fortune for first order transmission
Row is more stable, therefore longer length can be set to adapt to the processing compared with deep hole.
Further, the length of the secondary drive shaft preferably 40~65mm；The length of the secondary drive shaft most preferably 50
~60mm.
To use the beneficial effect of above-mentioned further scheme be: secondary drive shaft is in for the second level or Multi-stage transmission
High-speed cruising state can shake, it is therefore desirable to control its length when rotating at high speed due to gravity if length is too long
Degree, under above-mentioned length range, is not only able to guarantee that its operation is more stable, additionally it is possible to which the processing for effectively increasing whole device is deep
Degree.
Detailed description of the invention
