Abstract
The utility model relates to a diamond grinding head, comprising a power shaft and a grinding disc which is fixed on the power shaft and is provided with a grinding tool. The utility model is characterized in that the grinding disc is a grinding head body 5, and the interior of the body is provided with a sun wheel 3 and a planetary gear train 4 which form rotary movement corresponding to the grinding head body; the planetary gears are fixed on planetary shafts 6 which are uniformly arranged on the grinding head body in the circumferential direction. The grinding tool is saw blades 7 which can cut and process the margins of a processed work piece, and the saw blades 7 are fixed on the lower ends of the planetary shafts 6; the saw blades 7 form planetary cutting movement driven by the planetary gears. The utility model has the advantage that the existing coarse processing and fine processing are combined into one-step procedure to complete; accordingly, the tool consumption of the diamond is reduced, and the processing efficiency is improved; the dry processing and the wet processing can be realized.
Description
The utility model relates to a kind of hard brittle materia surfacing instrument that is used for.
Existing bistrique is to adopt the cross grinding mode to workpiece to be machined, and its shortcoming is 1) because the surplus of workpiece to be machined is to remove by grinding fully, generally need simultaneously through thick smart twice manufacturing procedure, so inefficiency, the diamond tool consumption is big; 2) can only adopt wet processing.
The purpose of this utility model provides a kind ofly can carry out the cutting removing method to workpiece to be machined, and thick, fine finishining is merged into the bistrique that a procedure is finished.
The purpose of this utility model is to realize like this.
A kind of diamond grinding head, it comprises line shaft and the mill that has grinding tool fixed thereon, it is characterized in that said dish is a grinding head body, be provided with the epicyclic train that sun gear rotates with respect to grinding head body within it, planetary gear is fixed on the planet axis, and said planet axis circumferentially is distributed on the grinding head body; Said grinding tool is to carry out the saw blade of cutting processing to the workpiece to be machined surplus, and is fixed on the lower end of planet axis; Said saw blade is done planet sawing campaign under planetary drive.
On said saw blade, be provided with the crushing block that surplus is played fragmentation.
The interplanar that said saw blade is vertical with line shaft has 1～5 ° angle α.
The optimum value at said α angle is 3 °
Said saw blade is 6～10, that is the planet pin that circumferentially is distributed on the grinding head body is 6～10, in general adopts 8 to get final product.
Good effect of the present utility model:
1. be merged into a procedure and finish because the utility model changes existing grinding method into cutting mode, and with original thick, fine finishining two procedures, thereby reduced adamantine instrument consumption widely, improved the efficient of processing.
2. the utility model can realize doing, wetting two kinds of processing.
Fig. 1 is an example structure figure of the present utility model.
Fig. 2 is another example structure of the utility model figure.
Fig. 3 is a upward view of the present utility model.
Be described in further details below in conjunction with accompanying drawing.
Among Fig. 11 is power input shaft (main shaft), the 2nd, and the line shaft supporting mass, the 3rd, be packed in sun gear on the supporting mass (stationary gear), the 4th, planetary gear, it is fixedly mounted on the planet axis, and planet axis then is installed on the grinding head body 5, can rotate.General planet axis can be provided with 6～10, and evenly circumferential cloth is on grinding head body, present embodiment is provided with 8, be mounted with the saw blade 7 that to carry out cutting processing to the workpiece to be machined surplus in the bottom of each planet axis, on saw blade, be provided with the wedge shape crushing block 8 of fragmentation, when allowance during greater than saw blade thickness, saw blade only cuts the root of surplus, and remainder will be extruded crackedly to fall, i.e. limit cutting edge fragmentation, thus realize once removing whole allowance.This has not only improved working (machining) efficiency greatly, has also reduced the consumption of diamond tool.For friction and the vibration that reduces saw blade, and the assurance saw blade also can be realized efficient removal to the allowance less than its thickness, 1～5 ° angle α is arranged between the vertical plane of saw blade and main shaft one power input shaft 1, the α of present embodiment is 2 °, the motion process of grinding head body and saw blade is: power is from main shaft 1 input, drive grinding head body 5 and slowly run, grinding head body 5 is being with the revolution of saw blade 7 low speed, also is being with the revolution of planetary gear 4 low speed.Planetary gear is in around stationary gear (sun gear) 3 revolution, because the engagement of gear pair and high speed rotation, thereby driving the rotation of saw blade high speed, i.e. the existing low speed revolution of saw blade has the high speed rotation again, thereby forms planet sawing campaign.
Fig. 2 is another embodiment of the present utility model, and the difference of it and embodiment 1 shows that mainly the revolution of saw blade and the power of rotation provide respectively.The power of embodiment 2 revolution is by hollow shaft 9 inputs, drives grinding head body 5 low speed rotation, and the grinding head body band the revolution of saw blade 7 low speed.Rotation power is by solid shafting 1 input, drives saw blade 7 high speed rotations through gear pair, thereby forms planet sawing campaign.
Fig. 3 is a upward view of the present utility model, and wherein 5 is grinding head body, the 7th, and the distribution of saw blade on grinding head body.
