Description

Class drill positioning and grinding mechanism

The present invention relates to a grinding mechanism, in particular to a class drill positioning grinding mechanism.

Please refer to FIG. 1, which shows a patent of the Republic of China (M577360) related to a hole drill grinding machine, which mainly fixes a hole drill (not shown) by an outer blade clamping unit 10 and an inner blade clamping unit 11, and A pair of grinding wheels 12 grind the hole drill. When the hole drill is fixed by the outer blade clamping unit 10, the outer edge of the hole drill abuts against the grinding wheel 12, when the hole drill is passed When the inner blade clamping unit 11 is fixed, the inner blade of the hole drill abuts against the grinding wheel 12, and by fixing the hole drill to the outer blade clamping unit 10 and the inner blade clamping unit 11, the After grinding the inner and outer edges of the hole drill, the length and angle of each edge can be averaged, which further solves the traditional manual grinding of hole drills by CNC lathes, resulting in a slight length and angle of each edge of the hole drill The problem of deviation.

However, before the above structure drills the hole drill, the positioning method of the hole drill is still dependent on manual to achieve the role of positioning. The traditional method of using manual positioning is relatively monotonous and repeats non-professional work, few young people They are willing to invest, and middle-aged and elderly people often suffer from the problem of positional deviation due to human error due to visual degradation. As a result, it is not only time-consuming, but also labor-intensive.

In addition, different operators will inevitably cause errors, which makes it difficult to improve the yield and accuracy of the hole drilling process. In addition, it is difficult to adjust the fixed standard position each time by manual positioning, which may easily affect the processing. Quality.

Therefore, how to solve the problems and deficiencies in the above-mentioned practice is the direction of improvement for this new model.

The purpose of the present invention is to provide a class drill positioning and grinding mechanism, which mainly enables the class drill to be positioned on the fixture unit more accurately before processing, so as to avoid the problem of human error, and further improve the class drill processing quality.
