Description

The present invention is a handle mounting structure that is problematic in view of this state of the art. The purpose of the present invention is to provide a solution for the purpose of solving the previous month. Facing tr: the mounting structure is configured to arrange the locking member so as to exit from the inner circumferential direction x and can retreat from the state toward the outer diameter, and the axis of the mandrel is along the axis of the mandrel. The shank mounting hole of the shank which extends in a girth direction and has a front end opening at the front end of the yoke is provided with a shank at the base end portion for receiving a concave portion of a part of the locking member, so that the one-touch type can be loaded and unloaded' The method is characterized in that: a coolant is supplied to the deer hole at a central portion in the radial direction of the hole portion and adjacent to a base end of the shank mounting hole to communicate with the shank mounting hole; and the coolant supply hole The front end portion is configured to be movable toward the base end side, and is disposed at a position closer to the front end of the valve body than the front end of the valve body, and is capable of abutting against the intermediate body and forming a liquid-tight state with the valve body. a sealing member; a second sleeve is disposed in the shank mounting hole, so that a base end of the shank is formed to abut the front end to move the axial direction toward the base end, and the pressing portion can abut the pressing portion The valve body allows the valve body to be separated from the sealing member, and The shank does not abut against the front end, and has an outer peripheral surface substantially equal to the outer diameter of the aperture of the shank mounting hole, and can form a state in which the locking member is retracted from the inner circumferential surface of the shank mounting hole toward the outer diameter; A valve body operating mechanism 1391141 having a pressing portion for pressing the valve body away from the sealing member is provided at the base end, and a valve body operating mechanism 1391141 having a contact surface for abutting the shank at the distal end is disposed in the shank mounting hole. According to the handle mounting structure of the present invention as described above, if the shank of the tool is inserted into the shank mounting hole of the mandrel, the base end of the shank causes the valve body disposed in the shank mounting hole of the mandrel The operating member moves toward the base end side of the shank mounting hole. By this movement, the pressing portion of the valve body operating member moves the valve body toward the proximal end side to separate the valve body from the sealing member. Therefore, even if the tool is not sold, the coolant can be supplied to the tool side only during the perforation. Moreover, if the shank of the tool is inserted into the shank mounting hole of the mandrel shank, the base end of the shank will cause the third sleeve disposed in the shank mounting hole of the mandrel portion toward the base end side of the shank mounting hole The locking member is caused to protrude from the inner peripheral surface of the crotch portion toward the inner diameter, and one of the locking members is locked to the recess of the shank. As a result, the handle can be attached to the mandrel in a one-touch manner. In the handle mounting structure, the second sleeve can be integrally connected with the valve body operating member. In this case, the number of parts can be reduced to the handle mounting structure, and the valve body and the valve body can also be The operating members are connected in one piece 'in this case, the number of parts can be reduced. In the shank mounting structure, if the outer diameter of the shank is formed such that the locking member is retracted from the inner circumferential surface of the shank mounting hole toward the outer diameter, the size of the access mounting hole can be inserted; and x The concave portion is formed in a long hole shape at a base end portion of the handle, so that the handle can be moved in the glaze direction by a predetermined distance in a state in which the one of the blocking members is received in the concave portion; The member is located at the front end position of the long hole-shaped recess of the shank. The state of the first sleeve causes the valve body to be separated from the sealing member, and the locking member is located at the base of the long hole-shaped recess of the shank. In the state of the end position, the first sleeve does not move the valve body away from the sealing member, and the locking member of the spindle is locked in the state in which the shank is locked by the shank when the locking member is located at the shank The state of the front end position of the long hole-shaped ω portion can supply the coolant, and on the other hand, when the locking member is located at the base end position of the long hole-shaped recess of the shank, the supply of the coolant can be stopped. status. That is, when the tool is used to pierce the surface to be machined, the force is used to abut the front end of the tool against the surface to be machined, and the valve body has not yet been separated from the sealing member, so no sputum is supplied to the tool side, from which the state is Further, pushing the cutter toward the base end moves the locking member of the spindle toward the front end in the recess of the shank, and the shank is inserted into the shank mounting hole of the spindle. As a result, the base end of the shank moves the second sleeve of the mandrel toward the base end to push the valve body toward the base end side to be separated from the sealing member. Therefore, a gap is formed between the valve body and the sealing member, so that the coolant supplied to the coolant supply hole is supplied from the gap through the shank mounting hole to the cutter side. In this way, even if the tool without the center pin is used, the coolant can be supplied to the cutting portion only during cutting. Further, the handle mounting structure is formed such that the locking recess is formed in a ring shape in a circumferential direction of the shank mounting hole when the shank mounting hole is adjacent to the front end of the first sleeve axial direction moving region; A stop % member is disposed in the locking recess, the stop ring member having an inner diameter that is slightly smaller than a base end of the shank, and a maximum diameter portion that is larger than the recess in a free state. An outer diameter; a shape in which a portion of the imaginary true circle protrudes toward the outer diameter 1339141 and the other portion retreats, and a portion protruding toward the outer diameter can be deformed in the axial direction of the shank mounting hole, In the configuration, when the handle is inserted into the handle mounting hole, the stop ring member is deformed in a state of being locked in the locking (4), and the handle is inserted into the handle mounting hole deeper by the stop ring member, and When pulled out, the stop ring member can be locked in the locking recess (4) to extract only the handle from the handle mounting hole.

Further, by the stop ring member, the 帛H is held in the shank mounting hole when the shank is inserted into the shank mounting hole or the yoke is pulled out. Therefore, the state in which the first sleeve is housed in the shank attachment hole can be maintained by the pole configuration. Further, the handle mounting structure is configured such that the thickness of the wall portion of the portion where the locking member is disposed is configured to be thicker than the thickness of the wall portion of the locking member

Next, the cam surface can be protruded toward the inner diameter side, and the cam surface can be pushed to the inside of the hole by the arm member, and the card can be pushed by the cam surface without moving. The stop member receives # ^ . is divided into the outer work side, and the elastic force of the second elastic member presses the portion of the second set of the locking member in a direction to form the 2 ew & In the state of the recess, by overcoming the elastic force of the first member, the sleeve is maintained in the non-moving state, and the retaining member can be in the retaining hole. If the outer diameter is retracted, if the configuration is as described above, the second sleeve may be moved in a direction opposite to the direction of the side of the ground side or the front end side. The shank of the mandrel is attached to the shank L, and the locking member moves the surface thereof in the axial direction while being in contact with the circumferential surface of the shank, and one of the inner diameter sides of the locking member is housed in the concave portion formed in the shank. When the locking member is housed in the recessed portion, the locked state of the second sleeve that has been locked until now is released. The second sleeve:: elastic force of the second elastic member Act, move in the direction of the party. If the handle is locked and held in the shank mounting hole of the mandrel. In this way, the handle can be attached to the shank mounting hole of the mandrel in a one-touch manner. On the other hand, when the handle is to be removed from the mandrel, if the second sleeve is moved in the opposite direction, the locking member accommodated in the recess can be retracted toward the outer diameter. The locking member is locked with the recess P of the handle. As a result, the tool-side handle can be simply removed from the mandrel. Therefore, when the operator installs the handle, it is only necessary to insert the handle into the shank mounting hole of the mandrel. When the shank is removed, the second sleeve only needs to overcome the direction of the second elastic member in the opposite direction to the one side. Move it and simply remove it. That is, the handle is attached to the mandrel and the handle is removed from the mandrel, which is easy to operate even with only one hand. Further, the shank can be detached from the mandrel by sliding the second sleeve in a direction opposite to the one direction (the direction of the front end 1339141 side or the base end side). Therefore, even if any object is mistakenly abutted on the second sleeve during the rotation, the handle does not fall off as in the prior art. In particular, the second sleeve is configured such that the second sleeve is pressed toward the proximal end to slide toward the proximal end to release the locking member, and the second sleeve is caused by foreign matter or protrusion on the side of the perforated object. When it is abutted, the handle will not fall off the mandrel.

The ring is just adjacent to the section 140a to seal the coolant from the valve body 1〇5. As described above, the structure is slightly complicated in comparison with the shank mounting structure of the first embodiment, but is excellent in terms of durability. In addition, in the diagram U of the second embodiment, the configuration of the main configuration of the embodiment i is the same as or the corresponding configuration. The reference symbol used in the configuration of the implementation of Wi is added with a reference symbol of ±100. Slightly repeated instructions. (Embodiment 3) In the above-described Embodiments 1 and 2, the supply or the stop of the coolant is performed from the coolant supply holes 3, 1〇3, and the valve 胄5, 1〇5 used is a sphere, but: As shown in Fig. 13, the inter-body 2〇5 has a tapered covering surface having a diameter different from that of the distal end portion and having a diameter reduced toward the distal end at the intermediate portion. The outer peripheral surface is replaced by a cylindrical shape. Even in the case of such a configuration, substantially the same effects as those of the first embodiment and the second embodiment can be exerted when the cold component is supplied. That is, the front end of the thick and light portion 2G5B connected to the end of the cylindrical valve body 2〇5 is further pressed by the base end of the shank 23〇 of the cutter 2〇C, and 22 1339141 is further pressed. The valve body 205 is separated from the 〇-shaped ring 204 disposed at the end of the coolant supply hole 2〇3, and can be supplied from the gap s (refer to FIG. 13) formed therebetween to the shank of the mandrel 200A. Inside the hole 202. Further, in the third embodiment, the large diameter portion 2〇5B which functions as the valve body operating member is integrally formed with the valve body 2〇5 at a lower portion of the valve body 205. Therefore, in the third embodiment, The first embodiment and the second embodiment are different. The first sleeve 220, which will be described later, does not have the function of pressing the valve body 205 away from the 〇-shaped ring 2〇4. Further, instead of the configuration of the third embodiment, a valve body operating member formed integrally with the valve body 205 may be formed as a separate individual. In the case of the handle mounting structure of the present embodiment 3, a coil spring is used as the first sleeve 220 instead of the first sleeve 20, 120 of the first embodiment, the second sleeve 20, 120; The stopper member 2 15 is pushed out toward the outer diameter. Further, the coil spring constituting the second sleeve 22 is also provided with the function of the coil spring 12 2 of the embodiment 2 of the spiral single ir 2 2 embodiment. In other words, when the lower cutter 200C is used, the tool 2〇〇c can be pushed out from the shank attachment hole 2〇2 φ toward the outside by elastic force. According to this configuration, since the number of components can be reduced, it is preferable. In addition, FIG. 12 and FIG. 13 showing the third embodiment of the present embodiment have the same configuration or corresponding configuration as the main configuration of the first embodiment, and the reference numerals used in the configuration of the known example 1 are added to 200.
