[0022] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] like Figures 1 to 4 As shown, a tool for machining an axial groove of an inner hole according to an embodiment of the utility model comprises a tool rod 1, a multi-edged blade 2 and a first pull rod 3. A first assembly groove 11 is provided on the left side of the front end of the tool rod 1, and an adjustment groove 12 is provided in the middle of the front end of the tool rod 1. The first assembly groove 11 and the adjustment groove 12 are connected to each other. The multi-edged blade 2 is used to be assembled in the first assembly groove 11 and to rotate in the adjustment groove 12. The first pull rod 3 is slidably connected to the tool rod 1 along the left and right directions. The left side of the first pull rod 3 passes through the adjustment groove 12 and is connected to the right side of the multi-edged blade 2. The first pull rod 3 is rotatably connected to the tool rod 1 with the central axis of the first pull rod 3 as the axis.
[0024] Specifically, the space size of the adjustment groove 12 is larger than the space size of the first assembly groove 11 , and the multi-edge blade 2 can be stably assembled in the first assembly groove 11 and can also rotate in the adjustment groove 12 .
[0025] In this embodiment, by providing the first pull rod 3, the multi-edged blade 2 can be pulled into the adjustment slot 12 by pulling the first pull rod 3 to move rightward. Since the multi-edged blade 2 can rotate in the adjustment slot 12, the multi-edged blade 2 can be driven to rotate by rotating the first pull rod 3 to adjust the angle of the multi-edged blade 2 and replace the cutting edge on the multi-edged blade 2. By pushing the first pull rod 3 to move leftward, the multi-edged blade 2 can be pushed into the first assembly slot 11 to stably assemble the multi-edged blade 2 to the tool bar 1. Therefore, by providing the first pull rod 3, the multi-edged blade 2 can be pulled into the adjustment slot 12 by the first pull rod 3 to rotate, and the cutting edge can be replaced without removing the multi-edged blade 2 from the tool bar 1, which is conducive to simplifying the process of replacing the cutting edge of the multi-edged blade 2, thereby improving work efficiency.
[0026] Alternatively, if Figures 1 to 4 As shown, the tool for processing the inner hole axial groove also includes a second pull rod 41 and a rotating shaft 42. A second assembly groove 13 is opened on the right side of the tool rod 1. The left side of the second pull rod 41 is rotatably connected to the right side of the first pull rod 3 through the rotating shaft 42. The second pull rod 41 is used to be set in the second assembly groove 13.
[0027] In this embodiment, a second pull rod 41 and a rotating shaft 42 are provided, and the second pull rod 41 is rotatably connected to the first pull rod 3 via the rotating shaft 42. During the process of replacing the cutting edge, the second pull rod 41 is driven to rotate relative to the first pull rod 3 about the rotating shaft 42, so that the second pull rod 41 is disengaged from the second assembly groove 13 until the second pull rod 41 is coaxial with the first pull rod 3. Pulling the second pull rod 41 to the right can drive the first pull rod 3 and the multi-blade blade 2 to move to the right synchronously, so that the multi-blade blade 2 enters the adjustment groove 12. Driving the second pull rod 41 to rotate can synchronously drive the first pull rod 3 and the multi-blade blade 2 to rotate, thereby replacing the cutting edge. At the same time, after the cutting edge is replaced, pushing the second pull rod 41 to the left can drive the multi-edged blade 2 to be assembled into the first assembly groove 11, and driving the second pull rod 41 to rotate relative to the first pull rod 3 with the rotating shaft 42 as the axis until the second pull rod 41 is inserted into the second assembly groove 13. The second pull rod 41 can be limited, thereby limiting the first pull rod 3 and the multi-edged blade 2, preventing the first pull rod 3 and the multi-edged blade 2 from moving in the left and right directions, which is beneficial to ensuring the stability of the multi-edged blade 2 installed in the first assembly groove 11.
[0028] Alternatively, if Figure 2 and Figure 4As shown, the tool for processing the inner hole axial groove also includes a first gear 51 and a second gear 52. The first gear 51 is connected to the multi-edged blade 2 and is sleeved on the first pull rod 3. The first gear 51 is coaxially distributed with the first pull rod 3. The second gear 52 is arranged in the adjustment groove 12 and is rotatably connected to the tool rod 1. The first gear 51 is used to mesh with the second gear 52.
[0029] In this embodiment, by providing the first gear 51 and the second gear 52, and sleeved on the first pull rod 3, the second pull rod 41 and the first pull rod 3 are driven to move rightward, the first gear 51 and the multi-blade blade 2 are brought into the adjustment slot 12, and the first gear 51 is meshed with the second gear 52 to drive the second gear 52 to rotate to drive the first gear 51 to rotate, thereby driving the multi-blade blade 2 to rotate. At the same time, by detecting the rotation angle of the second gear 52, the rotation angle of the multi-blade blade 2 can be calculated, so that the multi-blade blade 2 can be adjusted more accurately, and the accuracy of replacing the cutting edge of the multi-blade blade 2 is improved.
[0030] Alternatively, if Figure 2 and Figure 4 As shown, the tool for processing the inner hole axial groove also includes a turntable 53, which is connected to the second gear 52 and rotatably connected to the right side of the tool rod 1. The turntable 53 is coaxially distributed with the second gear 52, and scale lines are set on the turntable 53.
[0031] In this embodiment, the second gear 52 can be driven to rotate by rotating the turntable 53, and there is no need to use a tool to reach into the adjustment slot 12 to drive the second gear 52 to rotate, which is conducive to simplifying the process of replacing the cutting edge of the multi-edge blade 2. At the same time, a scale line is set on the turntable 53, and the angle of rotation of the scale line can be measured to confirm the angle of rotation of the turntable 53 and the second gear 52, so as to adjust the angle of the multi-edge blade 2 more accurately.
[0032] Optionally, the axial direction of the rotating shaft 42 is parallel to the axial direction of the knife rod 1, and the second assembly groove 13 is vertically arranged.
[0033] In this embodiment, the axial direction of the rotating shaft 42 is parallel to the axial direction of the arbor 1, and the second assembly groove 13 is vertically arranged. Then, during the rotation of the second pull rod 41 relative to the first pull rod 3, the second pull rod 41 can be rotated upward to be coaxial with the first pull rod 3, or it can be rotated downward until it is inserted into the second assembly groove 13. The second assembly groove 13 can be used to accommodate the second pull rod 41 to prevent the second pull rod 41 from interfering with the cutting work of the multi-edged blade 2.
[0034] Optionally, the multi-edge blade 2 is configured as an indexable four-edge groove blade, and the cutting edge of the indexable four-edge groove blade is a side edge.
[0035] In this embodiment, by setting the multi-edge blade 2 as an indexable four-edge groove blade and setting the cutting edge as a side edge, it is beneficial to improve the impact resistance of the indexable four-edge groove blade and increase the service life of the tool.
[0036] Optionally, the indexable four-edge groove insert is a center positioning insert, and the rear side surface and bottom surface of the first assembly groove 11 are respectively abutted against the rear side surface and bottom surface of the indexable four-edge groove insert.
[0037] In this embodiment, the center positioning blade can be directly replaced without secondary tool setting. The rear side and bottom surface of the first assembly groove 11 are respectively in contact with the rear side and bottom surface of the indexable four-edge groove blade, which is beneficial to increase the friction force by increasing the contact area, thereby improving the stability of the indexable four-edge groove blade set in the first assembly groove 11.
[0038] Alternatively, if Figure 2 As shown, the tool for machining the inner hole axial groove also includes a blade screw 6, which is arranged on the left side of the indexable four-edge groove blade and passes through the indexable four-edge groove blade to be connected to the first pull rod 3.
[0039] In this embodiment, by setting a blade screw 6, tightening the blade screw 6 can press the indexable four-edge groove blade onto the first pull rod 3, and the first pull rod 3 is limited by the second pull rod 41 and the second assembly groove 13, thereby further improving the stability of the indexable four-edge groove blade set in the first assembly groove 11.
[0040] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
