The inclination angle of the inclined transition part is 45 degrees as the same as that of the inclined guide part.
The utility model discloses has positive effect: the utility model discloses a structure sets up rationally, has certain height between its ring abrasive disc and the central circular disk to add man-hour at the chamfer, the product can not contact with the base member of chamfer emery wheel body, avoids work piece and chamfer emery wheel body base member striking to cause the damage, is favorable to improving the stability of chamfer and the efficiency of processing, also can improve the life of chamfer emery wheel body simultaneously greatly, and the suitability is strong and the practicality is good.
Drawings
In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is provided in connection with the following specific embodiments, taken in conjunction with the accompanying drawings, in which:
fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a sectional view taken along line A-A in FIG. 1.
Detailed Description
(example 1)
Fig. 1 and 2 show an embodiment of the present invention, wherein fig. 1 is a schematic structural diagram of the present invention; FIG. 2 is a sectional view taken along line A-A in FIG. 1.
Referring to fig. 1 and 2, a chamfer grinding wheel structure for cemented carbide comprises a chamfer grinding wheel body, the chamfer grinding wheel body comprises a central circular disc 1, a circular ring base body part 2 and a circular ring grinding disc 3, the inner diameter of the circular ring grinding disc is greater than the outer diameter of the circular ring base body part, the inner diameter of the circular ring base body part is greater than the outer diameter of the central circular disc, the circular ring grinding disc, the circular ring base body part and the central circular disc are parallel, an inclined transition part 4 is integrally formed between the outer edge of the central circular disc and the inner edge of the circular ring base body part, an inclined guide part 5 is integrally formed between the inner edge of the circular ring grinding disc and the outer edge of the circular ring base body part, and an installation round hole 6 for connecting a chamfer device is arranged at the center of the central circular disc.
The top surface of the circular ring base body part is 5mm away from the top surface of the central circular disc, and the top surface of the circular ring grinding disc is 10mm away from the top surface of the circular ring base body part.
The inclination angle of the inclined transition part is 45 degrees as the same as that of the inclined guide part.
The chamfering grinding wheel body base body is inwards sunken, so that a chamfered product cannot contact with the base body of the diamond grinding wheel during grinding, the collision of the processed product with the chamfering grinding wheel body base body is avoided, the stable operation of the chamfered product is guaranteed, and the processing precision and the finish of a processing surface are guaranteed. When the diamond grinding wheel is used, the diamond part can be uniformly ground, the whole diamond region can be well used for processing a product to be chamfered, and the service life of the diamond grinding wheel is obviously prolonged. The main body part of the chamfering grinding wheel body is mainly made of stainless steel, and after the diamond is ground, the chamfering grinding wheel body can be directly electroplated and then used repeatedly, so that the use cost is low.
The utility model discloses a structure sets up rationally, has certain height between its ring abrasive disc and the central circular disk to add man-hour at the chamfer, the product can not contact with the base member of chamfer emery wheel body, avoids work piece and chamfer emery wheel body base member striking to cause the damage, is favorable to improving the stability of chamfer and the efficiency of processing, also can improve the life of chamfer emery wheel body simultaneously greatly, and the suitability is strong and the practicality is good.
The standard parts used in the present embodiment can be purchased directly from the market, and the non-standard structural parts described in the specification can also be obtained directly by processing according to the common general knowledge of the prior art without any doubt, and the connection mode of the parts adopts the conventional means matured in the prior art, and the machines, parts and equipment adopt the conventional models in the prior art, so that the detailed description is not given here.
It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not limitations to the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And such obvious changes and modifications which fall within the spirit of the invention are deemed to be covered by the present invention.
