Japanese Utility Model Publication No. 1-99529 (FIGS. 3 (a), (b) and (c), FIGS. 8 (a) and (b))

The deburring tool of Conventional Example 1 has a drawback that it cannot cut and remove burrs, black skin and the like generated on the inner peripheral surface of the hole.
Further, since the vertically long cutting blade portion is structured to protrude from the cutting blade holding portion by the force of the spring, the cutting blade holding portion needs to have a certain length, resulting in a disadvantage that the deburring tool becomes long.

In the deburring tool of Conventional Example 2, as in the case of Conventional Example 1, there is a defect that burrs, black skin, and the like generated on the inner peripheral surface of the hole cannot be removed by cutting.
In addition, a temperature adjusting means for deforming the cutting edge portion is necessary, which not only increases the product cost of the tool and increases the price, but also has a drawback that it takes time and effort to operate the temperature adjusting means.

  Therefore, in the deburring tools in Conventional Example 1 and Conventional Example 2, problems that must be solved by cutting and removing burrs, black skin, and the like generated on the inner peripheral surface of the hole, and improving work efficiency. have.

  The gist of the present invention for solving the problems of the conventional example is that, when performing bolt joining, when a bolt hole is opened from one side of the joining member to the other side, the edge of the bolt hole on the other side is formed. A deburring machine that operates and removes the generated burrs from one side, and the deburring machine includes a cylindrical bite holder having a thickness corresponding to the hole diameter of the bolt hole, and one end of the bite holder. A shaft portion or a receiving portion which is provided and engages with a rotating portion of the electric rotary wrench, a first magnet member which is provided at the other end portion of the bite holder and adsorbs burrs, and a peripheral surface of the bite holder. A chevron bite member having a chevron for cutting that is disposed in the longitudinal direction on one side, protrudes by being biased outward, and can be pushed into the inside, and disposed on the other of the peripheral surfaces of the bite holder in the longitudinal direction. Can protrude outside and can be stored inside And flat bytes for cutting long shape, and a second magnet member for adsorbing cutting debris disposed burrs in the vicinity of the chevron section is to comprise at least a.

The chevron bite member includes a base, a long spring steel part integrally connected to the base part, and the chevron part integrally connected to the spring steel part, and a stopper is provided on the base part. Being configured to be attached to the inside of the tool holder by pressing a combined fixing screw;
The flat cutting tool is disposed inside the cutting tool holder by inserting screws into screw holes at both ends, and the hole diameter of the screw hole is formed larger than the shaft diameter of the screw. Being;
A concave portion for storing burr cutting waste is formed around the second magnet member;
Is included.

According to the deburring machine according to the present invention, when the bite holder is inserted from the upper side of the bolt hole and the angle portion is protruded to the lower side of the bolt hole, the angle portion protrudes outward by the biasing force of the spring steel portion. It contacts the edge of the bolt hole. Then, when the electric rotary wrench is driven to rotate the tool holder, the chevron part cuts and removes the burr at the edge of the bolt hole.
Moreover, the centrifugal force generated by the rotation of the tool holder causes the flat tool to protrude outward, and the burrs, black skin, and rust generated on the inner peripheral surface of the bolt hole are removed by cutting.
Chips such as burrs generated at the time of cutting are attracted to the first magnet member and stored in the concave portion, or are attracted to the second magnet member and stored in the concave portion, so that they do not scatter.
In this way, the deburring machine cuts and removes the burrs at the edge of the bolt hole on the other side of the joining member by working from one side, and simultaneously cuts and removes burrs and the like on the inner peripheral surface of the bolt hole. Therefore, it is possible to obtain an excellent effect that the working efficiency is extremely good.

The chevron bite member is composed of a base, a long spring steel part integrally connected to the base part, and a chevron part integrally provided to the spring steel part, and a stopper fixing screw is pressed against the base part. Since the spring steel part plays the role of a leaf spring by being configured to be attached inside the tool holder, the chevron part is urged outward and protrudes, and the chevron part can be pushed into the tool holder. is there.
That is, when the bite holder is inserted into the bolt hole, the chevron is pressed into the inner peripheral surface of the bolt hole and pushed into the bite holder. Further, when the chevron is protruded to the lower side of the bolt hole, the chevron protrudes outward and comes into contact with the edge of the bolt hole.
Furthermore, since the stopper fixing screw serves as a stopper, it can be caught in the upper edge of the bolt hole to prevent the deburring machine from falling to the other side (lower side) of the joining member. Has an excellent effect.

  The flat tool is inserted in the screw holes on both ends and is disposed inside the tool holder, and the hole diameter of the screw hole is formed larger than the shaft diameter of the screw. The flat tool can move freely within the range of the screw hole around the screw. As a result, when the tool holder rotates, the flat tool protrudes outward by the centrifugal force, and the flat tool has an excellent effect of cutting and removing burrs and the like on the inner peripheral surface of the bolt hole.

  The periphery of the second magnet member is formed with a recess for storing the cutting waste of the burr, so that the cutting waste of the burr at the edge of the bolt hole cut by the chevron is attracted to the second magnet member and becomes a recess. Since it accumulates, the outstanding effect that cutting waste does not scatter is produced.

The deburring machine 11 includes a cylindrical cutting tool holder 12, a shaft portion 13 provided at one end of the cutting tool holder 12, and a cutting tool holder 12. A first magnet member 14 provided at the other end of the tool (see FIGS. 5 and 6), and a chevron bite member 16 having a chevron part 15 for cutting disposed on one of the peripheral surfaces of the tool holder 12 in the longitudinal direction. The cutting tool is provided with a cutting tool 17 disposed in the longitudinal direction on the other peripheral surface of the tool holder 12 and a second magnet member 18 provided in the vicinity of the chevron 15.

The deburring machine 11 is directed from one side 19a (upper side in FIGS. 7 to 9) to the other side 19b (lower side in FIGS. 7 to 9) of the joining member 19 when performing the bolt joining operation. When the bolt hole 20 is opened, the burr 21 generated at the edge of the bolt hole 20 on the other side 19b is operated and removed from the one side 19a (see FIGS. 7 to 9).
In addition, the deburring machine 11 uses the thing of the bite holder 12 of the thickness corresponding to the hole diameter of the bolt hole 20 which performs the operation | work of bolt joining suitably.

  The bite holder 12 is formed in a cylindrical shape and has a required length. Further, as described above, the tool holder 12 is appropriately selected to have a thickness corresponding to the hole diameter of the bolt hole 20 that performs the bolt joining operation.

  The shaft portion 13 is provided at one end portion of the tool holder 12 and has a required length. Further, the shaft portion 13 engages with a turning portion (socket) 23 of the electric rotary wrench 22 and transmits a rotational force to the bite holder 12 during the driving (see FIGS. 7 to 9).

The first magnet member 14 is formed in a cylindrical shape, and is provided inside the other end of the tool holder 12. Further, a concave portion 24 is provided between the first magnet member 14 and the tip end portion 12a of the tool holder 12 (see FIGS. 5 and 6).
The first magnet member 14 plays a role of adsorbing the cutting waste of the burr 21 cut by the chevron portion 15 of the chevron bite member 16, and burrs, black skin on the inner peripheral surface of the bolt hole 20 cut by the flat bite 17, It plays the role of adsorbing rust cutting waste. Those cutting wastes are stored in the concave portion 24.

The chevron bite member 16 includes a base portion 25, a long spring steel portion 26 integrally connected to the base portion 25, and a cutting chevron portion 15 integrally connected to the spring steel portion 26. The stopper fixing screw 27 is pressed against the 25 screw receiving portions 25a and attached to the inside of the bite holder 12 (see FIGS. 5 and 6).
In this case, since the spring steel part 26 serves as a leaf spring, the chevron 15 is urged outward and protrudes, and the chevron 15 can be pushed into the bite holder 12 (FIG. 5). (See arrow E).

  That is, when the bite holder 12 is inserted into the bolt hole 20, the angled portion 15 is pressed into the inner peripheral surface of the bolt hole 20 and is pushed into the bite holder 12. Further, when the angled portion 15 protrudes to the lower side of the bolt hole 20, the angled portion 15 protrudes outward and comes into contact with the edge of the bolt hole 20.

  Further, the stopper / fixing screw 27 serves as a stopper. That is, since the stopper / fixing screw 27 is caught on the upper edge of the bolt hole 22, the deburring machine 11 is prevented from inadvertently dropping to the other side (lower side) 19 b of the joining member 19.

  The flat tool 17 is formed in a vertically long and flat plate shape so that burrs and the like can be cut by the outer portion 17b. Further, both corners 17a of the flat tool 17 are formed in an R shape so that they are not caught when abutting against the edge of the bolt hole 20 (see FIGS. 5 and 6).

In addition, the flat cutting tool 17 is disposed inside the cutting tool holder 12 by inserting a screw 29 into screw holes 28 at both ends, and the hole diameter of the screw hole 28 is larger than the shaft diameter of the screw 29. (See FIGS. 5 and 6). Accordingly, the flat cutting tool 17 can move within the screw hole 28 around the screw 29. As a result, when the cutting tool holder 12 rotates, the flat cutting tool 17 protrudes outward by the centrifugal force. Therefore, the flat cutting tool 17 can cut and remove burrs, black skin, and rust on the inner peripheral surface of the bolt hole 20.
In FIG. 6, reference numeral 31 denotes a female screw portion to which the screw 29 is screwed, and the female screw portion 31 is formed inside the bite holder 12.

  The second magnet member 18 is formed in a spherical shape and is provided in the vicinity of the mountain-shaped portion 15. A recess 30 is formed around the second magnet member 18. The cutting waste of the burr 21 at the edge of the bolt hole 20 cut by the chevron 15 is attracted to the second magnet member and stored in the recess 30.

  The deburring machine 11 configured as described above inserts the bite holder 12 from the upper side of the bolt hole 20 (see arrow B in FIG. 7). When the tool holder 12 is inserted into the bolt hole 20 in this manner, the chevron 15 is pressed into the inner peripheral surface of the bolt hole 20 and is pushed into the tool holder 12.

  When the chevron 15 protrudes to the lower side of the bolt hole 20, the chevron 15 protrudes outward by the urging force of the spring steel part 26 and comes into contact with the edge of the bolt hole 20 (see FIG. 8). When the electric rotary wrench 22 is driven to rotate the tool holder 12 (see arrow C in FIG. 8), the chevron 15 cuts and removes the burr 21 at the edge of the bolt hole 20 (see FIG. 8). The cutting waste of the burr 21 generated at this time is attracted to the second magnet member and stored in the concave portion 30, or is attracted to the first magnet member 14 and stored in the concave portion 24, so that it does not scatter.

  Further, due to the centrifugal force generated by the rotation of the tool holder 12, the flat tool 17 protrudes outward (see FIG. 8), and burrs, black skin, and rust generated on the inner peripheral surface of the bolt hole 20 are removed by cutting. Cutting chips such as burrs generated at this time are attracted to the second magnet member 18 and stored in the concave portion 30 or are attracted to the first magnet member 14 and stored in the concave portion 24 so that they do not scatter.

  After the work of removing the burr 21 is completed, the deburring machine 11 is pulled out to the upper side of the bolt hole 20 (see arrow D in FIG. 9). At this time, the flat cutting tool 17 comes into contact with the inner peripheral surface of the bolt hole 20 and is housed therein, and the chevron 15 is in pressure contact with the inner peripheral surface of the bolt hole 20 so as to be inside the cutting tool holder 12. It is pushed in (see FIG. 9).

  In this manner, the deburring machine 11 can work by removing the burr 21 at the edge of the bolt hole 20 on the other side 19b of the joining member 19 from the one side 19a. And since the burr | flash 21 of the edge part of the bolt hole 20 is cut and removed, the burr | flash etc. in the internal peripheral surface of the bolt hole 20 can be cut and removed, Therefore Work efficiency is very favorable.
