Test and comparison cutter: choose normal diamond sharpening disk, without chip space cutterhead, have chip space without cutting angle of throat
Disk has chip space to have cutting edge cutterhead (basil of cutting edge is 90 degree), have chip space to have the cutting edge cutterhead (basil of cutting edge
Be 70 degree), there is chip space to have cutting edge cutterhead (basil of cutting edge is 60 degree) each ten that cutter is tested.
It should be noted that the grinding part diameter of above-mentioned test cutterhead is identical namely cutterhead is straight in the grinding of glass surface
Diameter is identical.
Test table
The embodiment of the present invention provides a kind of design method of balancing loop again:
Wherein, d indicates the aperture for matching repeated hole, and D1 indicates that the outer diameter of the ring body, D2 indicate the internal diameter of the ring body,
L indicates that the axial length of the ring body, W indicate the ring width of the ring body.
Step S01, determine that the outer diameter D 1 of ring body, the outer diameter D 1 of ring body are equal to 1.1-1.3 times of knife handle outer diameter；
Step S02, determine that the internal diameter D2 of ring body, the internal diameter D2 and knife handle crest clearance of ring body cooperate, grade of tolerance H8
Or H10；
Step S03, the width W=D1-D2 of ring body is determined；
Step S04, the axial length L of ring body is determined, the axial length of ring body is equal to the axial direction of 0.10-0.13 times of knife handle
Length；
Step S05, the aperture d, d=0.5L+0.02D+0.2W+0.1 for matching repeated hole are determined.
The embodiment of the present invention provides a kind of using balancing loop adjustment knife handle/cutterhead center of gravity method again:
Number of the balancing loop side with repeated hole is 24 or 30 or 36；There are five types of regulating device of the insertion with repeated hole
Specification, weight can be respectively 0.1g, 0.2g, 0.3g, 0.4g, 0.5g.
By taking 30 balancing loops with repeated hole as an example, specific regulating step is as follows:
Step S10, dynamic balancing ring set is installed on knife handle clearance fit；
Step S20, the regulating device of 4 0.3g is installed on in repeated hole, one is installed every an angle of 90 degrees, due to gap
Cooperation, regulating device withstand knife handle and also act as the effect that balancing loop is fixed on to knife handle；
Step S30, knife handle component/cutter head assembly center of gravity is tested using barycenter test instrument, first time is enabled to measure
Laying particular stress on position is the first weighting position, and the weighting amount measured for the first time is the first weighting amount；
Step S40, the first weighting amount at position is laid particular stress on according to first measured, if first lays particular stress on position in step S20
Some position in 4 regulating devices of installation, then corresponding regulating device here of dismantling, is surveyed using barycenter test instrument
Knife handle component/cutter head assembly center of gravity is tried, enabling second of weighting amount measured is the second weighting amount；According to the second weighting amount
The corresponding combination installation of size or five kinds of weight specifications of disassembly regulating device；
Step S50, the weighting amount at position is laid particular stress on according to first measured, if first lays particular stress on position not in step S20 peace
Any one of 4 regulating devices of dress position, then being installed according to the opposite that the first weighting amount is laid particular stress at position first
The regulating device of dimension；
Step S60, step S40, step S50 are repeated until knife handle component/cutter head assembly center of gravity and knife handle are axially coincident.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
