DETAILED DESCRIPTION
[0024] The following is combined with Figure 1-Figure 5 This application is described in further detail.
[0025] An embodiment of the present application discloses a slotting machine tool assembly for a machining center.
[0026] A slotting tool assembly for a machining center, referring to Figure 1-3 , including a connecting sleeve 1, a tool handle 2 and a tool head 3. The connecting sleeve 1 is fixedly installed on the lifting shaft of the slotting machine of the machining center, so that the slotting machine can use the tool handle 2 and the tool head 3 to cut the keyway of the workpiece.
[0027] Reference Figure 1-2The tool handle 2 is detachably mounted on the bottom of one end of the connecting sleeve 1, and the tool head 3 is fixedly mounted on the bottom of one side of the tool handle 2. The tool handle 2 and the tool head 3 constitute an existing slotting tool, and its internal structure and principle have been disclosed, so I will not go into details here. A baffle 4 is fixedly mounted on the bottom of the side of the tool handle 2 away from the tool head 3. The baffle 4 can protect one end of the tool handle 2 after it moves during cutting.
[0028] Reference Figure 1-2 A plurality of fixing holes 12 are provided on the outer wall of one end of the connecting sleeve 1, and the top end of the knife handle 2 is fitted into one end of the connecting sleeve 1. A mounting hole 11 is provided in one end of the connecting sleeve 1, and the top end of the knife handle 2 is fitted into the mounting hole 11 of the connecting sleeve 1. The connecting sleeve 1 can connect and limit the top end of the knife handle 2 through the mounting hole 11.
[0029] Reference Figure 1 、 Figure 2 and Figure 4 The connecting mechanism includes several fixing blocks 23 slidably arranged in the top end of the knife handle 2, and a spring 22 arranged in the top end of the knife handle 2 for inserting the fixing block 23 into the corresponding fixing hole 12. The outer wall of the top end of the knife handle 2 is provided with several limiting grooves 21. The spring 22 is fixedly connected in the limiting groove 21 of the knife handle 2. One end of the fixing block 23 is slidably connected in the limiting groove 21 of the knife handle 2. The knife handle 2 can fix the spring 22 through the limiting groove 21 and limit one end of the fixing block 23. The spring 22 and the fixing block 23 are fixedly connected. Under the elastic force of the spring 22, the fixing block 23 can be inserted into the corresponding fixing hole 12, thereby connecting and fixing the connecting sleeve 1 and the knife handle 2 to install the tool.
[0030] Reference Figure 1 、 Figure 2 and Figure 4 A rotating rod 25 is rotatably provided in the groove opened at the top of the knife handle 2, and the top of the rotating rod 25 extends to the outside of the connecting sleeve 1. A connecting rope 24 is fixed on the side of the fixing block 23 close to the spring 22, which passes through the knife handle 2 and is wrapped around the outer wall of the rotating rod 25. After the staff rotates the rotating rod 25, the wound connecting rope 24 will be reeled in, so that the connecting rope 24 pulls the fixing block 23 away from the fixing hole 12, so that the knife handle 2 is unfixed, which makes it convenient for the staff to pull the knife handle 2 out of the connecting sleeve 1 to replace the tool.
[0031] Reference Figure 1 、 Figure 2 and Figure 4The top of the handle 2 is connected to a rotating block 27, and the rotating rod 25 is fixedly connected to the top center of the rotating block 27. The top of the rotating rod 25 is fixedly provided with a gripping rod 26 located above the connecting sleeve 1. The rotating block 27 is cylindrical in shape. The rotating block 27 can connect the handle 2 and the rotating rod 25, so that the rotating rod 25 can rotate on the handle 2 without disengaging. The groove opened at the top of the handle 2 is communicated with the top of the mounting hole 11, so that the top of the rotating rod 25 can extend from the top of the connecting sleeve 1. The staff can hold the gripping rod 26 to drive the rotating rod 25 to rotate.
[0032] Reference Figure 2 、 Figure 3 and Figure 5 A self-locking mechanism is provided at the top of the knife handle 2 for one-way locking of the rotating rod 25 after rotation. The self-locking mechanism includes a ratchet 5 fixed on the outer wall of the rotating rod 25, and a pawl 51 engaged with the outside of the ratchet 5. The pawl 51 is rotatably connected to the groove opened at the top of the knife handle 2. A spring piece 52 for pushing the pawl 51 toward the ratchet 5 is fixed in the groove opened at the top of the knife handle 2. A round rod is fixed in the groove opened at the top of the knife handle 2. The pawl 51 is rotatably connected to the outer wall of the round rod. The spring piece 52 can push the pawl 51 toward the ratchet 5, so that the pawl 51 can withstand the ratchet teeth on the ratchet 5 to perform one-way locking of the ratchet 5 and the rotating rod 25.
[0033] When the rotating rod 25 rotates to reel in the wound connecting rope 24, the engagement of the ratchet 5 and the pawl 51 can lock the rotated rotating rod 25 in one direction, so that the rotating rod 25 cannot rotate in the opposite direction temporarily, thereby preventing the staff from accidentally releasing the rotating rod 25 and causing the grip 26 to rotate rapidly under the tension of the connecting rope 24 and the spring 22, thereby preventing the staff from injuring their hands. The operation difficulty when rotating the rotating rod 25 is also reduced.
[0034] The implementation principle of a slotting tool assembly for a machining center in the embodiment of the present application is as follows:
[0035] When in use, the connecting sleeve 1 is fixedly mounted on the lifting shaft of a slotting machine of an external machining center, so that the slotting machine can use the tool handle 2 and the tool head 3 to cut the keyway of the workpiece;
[0036] When the tool needs to be replaced, the staff can hold the grip 26 to drive the rotating rod 25 to rotate. After the rotating rod 25 rotates, the wound connecting rope 24 is reeled in, so that the connecting rope 24 pulls the fixing block 23 away from the fixing hole 12, so that the knife handle 2 is unfixed, which makes it easier for the staff to pull the knife handle 2 out of the connecting sleeve 1 to remove the tool. At the same time, the engagement of the ratchet 5 and the pawl 51 can lock the rotating rod 25 in one direction, making it temporarily unable to rotate in the opposite direction, thereby reducing the difficulty of operating the rotating rod 25;
[0037] Then insert the handle 2 of the other tool into the corresponding mounting hole 11 in the connecting sleeve 1, and then use a thin rod to pick up the pawl 51 from one side of the ratchet 5. At this time, under the tension of the connecting rope 24 and the spring 22, the grip rod 26 and the rotating rod 25 will quickly rotate in the opposite direction, thereby unwinding the connecting rope 24, so that the several fixing blocks 23 are quickly inserted into the corresponding several fixing holes 12 under the elastic force of the spring 22 to connect, install and fix the connecting sleeve 1 and the handle 2, thereby completing the tool replacement process, which is more time-saving and convenient.
[0038] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
