本考案は貫通穴の両端面に面取り加工を行なう
工具に関するものである。[Detailed Description of the Invention] The present invention relates to a tool for chamfering both end faces of a through hole.
従来、一般機械加工に於いて貫通穴を有する製

作等、時間的ロスが多い。 Conventionally, in general machining, after drilling a product with a through hole, some burrs occur on the drilling side and the hole penetration side, and in order to remove the burrs, a chamfering tool is used and finishing is done by machine or hand. However, if the hole entrance and hole exit sides are chamfered at the same time after drilling with a machine, two types of chamfering tools are required: a hole entrance side chamfering tool and a hole exit side chamfering tool. , there is a lot of time loss due to tool changes and machine operations.
本考案は上述した従来の実情に鑑み、１つの面
取り工具で両側の面取加工を能率よく行なえるこ
とを目的としたものである。 In view of the above-mentioned conventional situation, the present invention aims to efficiently chamfer both sides using a single chamfering tool.

FIG. 1 is a sectional view of a double-sided chamfering tool, showing the state of chamfering the entrance side of a through hole, and FIG. 2 is a side view of the tip of the double-sided chamfering tool. Further, FIG. 3 is a sectional view showing a chamfered state on the exit side of the through hole.

Reference numeral 4 denotes a chamfering blade, and the machining blades are provided at positions A and B, and chamfering is performed on both the hole entrance side and hole exit side of the through hole. A pin 5 rotatably supports the chamfering blade 4. A roller 6 is rotatably supported by a pin 7, a bush 8, and a thrust washer 9. The bush 8 and thrust washer 9 are made of anti-seize material. Reference numeral 10 denotes a spring guide tube, and reference numeral 11 refers to a spring that supports the chamfering blade 4 by the spring force against the surface machining reaction force of the processing blade A, and after the chamfering of the processing blade A is completed, the outer diameter of the roller 6 is adjusted to the product by mechanical feeding. It hits the top surface of
The spring 11 also supports the reaction force corresponding to the subsequent feed amount (△). 12 is a stopper, which also serves as a bearing box for the thrust ball bearing 13, and 14 is an adjustment screw, and by means of a retaining ring 15, the stopper 12 and the thrust ball bearing 13 are rotatably integrated as shown in the figure, and the feed amount (△) dimension is adjusted. can be adjusted and fixed with a round nut 16 after adjustment.

とが判明するものである。 To perform double-sided chamfering of a through hole drilled in a product using the above device, attach this chamfering tool to the spindle of the drilling machine, and press the guide pad 3.
By guiding the tool into the inner diameter of the through hole and inserting this tool, and applying rotation and feed, the machining blade A of the chamfering blade 4 first processes the surface of the entrance side of the through hole using the reaction force of the spring 11. The chamfering blade 4 rotates around the pin 5 when the outer diameter of the roller 6 hits the top surface of the product, and the machine spindle 1 is rotated to feed the feed dimension (△) amount. Accordingly, the machining blade B chamfers the hole exit side of the through hole. In this case, spindle 1
The feed is done by hand, and the end surface of the stopper 12 touches the top surface of the product, and it is rotatable by a thrust ball bearing, so when the stopper 12 stops rotating, it becomes the final end of the feed. This shows that the chamfering process on the exit side of the hole has been completed.

This is shown in FIG. Its configuration is the same except for the above-mentioned unnecessary parts, and its operation is also the same except for the feed control.

出来ると共に面取り工具費が低減出来る。 According to the present invention, the chamfering process for removing burrs on the entrance side and the exit side of a through hole, which previously required two types of chamfering tools each, can be performed with one type of double-sided chamfering tool. It is possible to reduce tool exchange and machine operation time during chamfering, and also to reduce chamfering tool costs.
