Description

Technical Field

[0001] The invention relates to the technical field of carbon fiber material cutting tools, in particular to a carbon fiber composite material cutting tool. Background Art

[0002] A boring tool is a type of hole processing tool, generally with a round handle. A boring tool has one or two cutting parts and is specially used for rough cutting, semi-finishing cutting or finishing of existing holes. Boring tools can be used on boring machines and lathes. After the carbon fiber composite material is opened, a boring tool is needed to perform secondary cutting on the hole.

[0003] In the prior art, the boring tool is mainly composed of a tool handle and a tool seat, and the tool handle and the tool seat are connected by bolts, which results in the need to repeatedly turn two bolts when separating the tool seat and the tool handle, and the operation convenience is relatively low. A rotating disk for adjusting the blade position is provided on the tool seat, and a hexagonal lever groove is provided in the middle of the rotating disk. During the rotation process of the boring tool, a lot of carbon fiber fragments will be splashed, and these fragments will enter the inside of the lever groove. Since the diameter of the lever groove is small, the debris splashed into the inside of the lever groove is often difficult to clean. Summary of the invention

[0004] In view of the problem that it is difficult to separate the tool handle and the tool seat in the prior art, the present invention provides a carbon fiber composite material cutting tool.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a carbon fiber composite material cutting tool, comprising a tool holder and a tool handle, the tool holder is rotatably connected with a rotating disk, a lever groove is provided at the center of the rotating disk, a blade is provided on the tool holder, a connecting seat is fixedly connected to the top of the tool holder, a fixing mechanism is provided inside the connecting seat, and a transmission mechanism is provided inside the tool holder; The knife handle is provided with an adjustment mechanism for releasing the connection with the knife seat, the adjustment mechanism comprises a rotating ring, an annular groove, a second magnet and a conical groove, the rotating ring is fixedly connected with a symmetrically arranged first magnet, the annular groove is provided on the knife handle, the rotating ring is rotatably connected inside the annular groove, the specific shapes of the first magnet and the second magnet are both annular, and the conical groove is provided at the bottom end of the knife handle; The knife seat is provided with a blocking mechanism for blocking the lever groove, and the blocking mechanism includes a mounting groove and a round rod. Two support seats are fixedly connected inside the mounting groove, and the bottom ends of the round rods are fixedly connected with blocking rings. The round rods are fixedly connected with tension rods, and the tension rods are rotatably connected with connecting rods.

[0006] Specifically, the bottom ends of the round rods are rotated to penetrate the center position of the support seat, the bottom ends of the round rods are rotated to penetrate the outer wall of the knife seat and are fixedly connected to the blocking ring, the specific shape of the tension rod is an L-shaped setting, and one end of the tension rod is slidably inserted into the corresponding support seat.

[0007] Specifically, the fixing mechanism includes two sliding grooves, the interior of each sliding groove is fixedly connected with a guide rod, the interior of each sliding groove is fixedly connected with a spring, and the interior of each sliding groove is slidably connected with a fixing rod.

[0008] Specifically, the sliding groove is symmetrically opened on the connecting seat, one end of the guide rod passes through the hollow position of the spring, one end of the spring is fixedly connected to the corresponding fixed rod, the fixed rod is slidably connected to the corresponding guide rod, the fixed rod is fixedly connected to the second magnet, one end of the fixed rod and the second magnet slide through the outer wall of the tool handle and are located inside the annular groove.

[0009] Specifically, the transmission mechanism includes a rotating rod and a guide seat. There are two guide seats in total. A driving gear is fixedly connected to the rotating rod. A driven rack is slidably connected to the two guide seats. A vertical rod is fixedly connected to the driven rack.

[0010] Specifically, the rotating rod is rotatably connected to the knife seat, the driving gear is meshed with the driven rack, the vertical rods are rotatably connected to the corresponding connecting rods, one end of the rotating rod is located inside the mounting groove, the guide seat is symmetrically fixedly connected inside the mounting groove, and the driven rack and the vertical rod are both located inside the mounting groove.

[0011] Beneficial effects of the present invention: (1) The position of the fixing rod can be flexibly adjusted by the repulsive force between the first magnet and the second magnet. When the first magnet is rotated by the rotating ring, the first magnet and the second magnet will be in the same level relative to each other, thereby generating a huge repulsive force, so that the fixing rod is retracted into the inside of the connecting seat. At this time, the fixation between the tool handle and the tool seat is released, avoiding the problem of reduced operating convenience caused by repeated rotation of the bolt.

[0012] (2) When the boring tool is in working condition, the two blocking rings can provide blocking for the lever groove on the rotating disk to prevent carbon fiber fragments from splashing into the lever groove during processing, thus avoiding the difficulty in cleaning the lever groove. In addition, the position adjustment operation of the blocking piece is very convenient through the coordinated linkage of various components. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0017] See also Figures 1 to 7 , the present invention provides the following technical solutions: Embodiment 1: A carbon fiber composite material cutting tool comprises a tool holder 1 and a tool handle 2, wherein a rotating disk 3 is rotatably connected to the tool holder 1, a lever groove 4 is provided at the center of the rotating disk 3, a blade 5 is provided on the tool holder 1, a connecting seat 6 is fixedly connected to the top of the tool holder 1, and a fixing mechanism 7 is provided inside the connecting seat 6; The fixing mechanism 7 includes two sliding grooves 71, each of which is fixedly connected to a guide rod 72, each of which is fixedly connected to a spring 73, and each of which is slidably connected to a fixing rod 74; When in use, the tool handle 2 can be installed on the boring machine, and the tool handle 2 and the tool seat 1 can be controlled to rotate by the boring machine. The rotating tool seat 1 will drive the blade 5 to rotate together. At this time, the rotation of the blade 5 will cut the carbon fiber composite material that needs to be cut. The staff can also insert an external tool into the lever groove 4. At this time, the rotating disk 3 can be driven to rotate through the connection between the external tool and the lever groove 4. When the fixed rod 74 moves in a direction away from each other inside the sliding groove 71, the spring 73 will be stretched and deformed. When the fixed rod 74 no longer generates tension on the spring 73, the spring 73 will drive the fixed rod 74 to retract into the sliding groove 71, and the guide rod 72 is the movement guide of the fixed rod 74.

[0018] Embodiment 2: The technical solution of this embodiment is different from that of Embodiment 1 in that: the knife handle 2 is provided with an adjustment mechanism 9 for releasing the connection with the knife seat 1, the adjustment mechanism 9 comprises a rotating ring 91, an annular groove 92, a second magnet 93 and a tapered groove 94, the rotating ring 91 is fixedly connected with a symmetrically arranged first magnet 95, the annular groove 92 is provided on the knife handle 2, the rotating ring 91 is rotatably connected inside the annular groove 92, the specific shapes of the first magnet 95 and the second magnet 93 are both annularly arranged, and the tapered groove 94 is provided at the bottom end of the knife handle 2; The sliding groove 71 is symmetrically provided on the connecting seat 6, one end of the guide rod 72 passes through the hollow position of the spring 73, one end of the spring 73 is fixedly connected to the corresponding fixing rod 74, the fixing rod 74 is slidably connected to the corresponding guide rod 72, the fixing rod 74 is fixedly connected to the second magnet 93, one end of the fixing rod 74 and the second magnet 93 slide through the outer wall of the handle 2 and are located inside the annular groove 92; When in use, the rotating ring 91 can be directly rotated. The rotation of the rotating ring 91 inside the annular groove 92 will drive the first magnet 95 to rotate together. The first magnet 95 will slowly rotate to a position opposite to the second magnet 93 during the rotation. At this time, the relative positions of the first magnet 95 and the second magnet 93 are at the same level, and a great repulsive force will be generated between the first magnet 95 and the second magnet 93. This repulsive force is greater than the contraction force of the spring 73. The position of the first magnet 95 remains unchanged, and the two second magnets 93 will both retract into the interior of the sliding groove 71. The second magnet 93 will drive the fixed rod 74 to move together. The retraction of the fixed rod 74 into the sliding groove 71 will squeeze and contract the spring 73. At this time, as the fixed rod 74 retracts, the fixed rod 74 no longer penetrates the outer wall of the handle 2. The connection limit between the connecting seat 6 and the knife handle 2 is released, and the knife handle 2 can be directly pulled out from the knife seat 1. At this time, the knife handle 2 and the knife seat 1 are completely disassembled, and the operation is extremely convenient. When the knife handle 2 is connected to the knife seat 1, the recessed position at the bottom of the knife handle 2 can be directly inserted into the corresponding connecting seat 6. When the recessed part at the bottom of the knife handle 2 is initially connected with the connecting seat 6, the conical groove 94 will squeeze the top ends of the two second magnets 93. At this time, the second magnets 93 will be pressed and drive the fixing rod 74 to retract into the sliding groove 71. When the bottom end of the knife handle 2 abuts against the top end of the knife seat 1, there will be no components to squeeze the second magnet 93 and the fixing rod 74. Therefore, the spring 73 will drive the fixing rod 74 and the second magnet 93 to re-penetrate the knife handle 2. At this time, the connection between the knife handle 2 and the knife seat 1 is complete.

[0019] It also includes: a blocking mechanism 10 for blocking the lever groove 4 is provided on the tool holder 1, the blocking mechanism 10 includes a mounting groove 101 and a round rod 102, two support seats 103 are fixedly connected inside the mounting groove 101, the bottom ends of the round rods 102 are fixedly connected with blocking rings 104, the round rods 102 are fixedly connected with tension rods 105, the tension rods 105 are rotatably connected with connecting rods 106, the bottom ends of the round rods 102 are rotatably passed through the center position of the support seats 103, the bottom ends of the round rods 102 are rotatably passed through the outer wall of the tool holder 1 and are fixedly connected with the blocking rings 104, the specific shape of the tension rods 105 is an L-shaped setting, and one end of the tension rods 105 is slidably inserted into the corresponding support seats 103; The transmission mechanism 8 includes a rotating rod 81 and a guide seat 82.

A vertical rod 85 is fixedly connected to the driven rack 84. The rotating rod 81 is rotatably connected to the knife seat 1. The driving gear 83 is meshed with the driven rack 84. The vertical rods 85 are rotatably connected to the corresponding linkage rods 106. One end of the rotating rod 81 is located inside the mounting groove 101. The guide seats 82 are symmetrically fixedly connected inside the mounting groove 101. The driven rack 84 and the vertical rod 85 are both located inside the mounting groove 101. When in use, the tool holder 1 is in the working state, and the two closed blocking rings 104 will provide blocking for the rotating disk 3 on the tool holder 1 to prevent processing debris from splashing into the inside of the lever groove 4. When it is necessary to open the blocking ring 104, the two driven racks 84 need to be moved in advance. The rotating rod 81 can be held and then directly rotated. The rotation of the rotating rod 81 will drive the driving gear 83 to rotate, and the rotation of the driving gear 83 will simultaneously drive the two driven racks 84 to move. At this time, the two driven racks 84 will move toward the middle direction, and the guide seat 82 will guide the movement of the two driven racks 84, and the driven racks 84 will also move when moving. The vertical rod 85 will be driven to move, and the movement of the vertical rod 85 will pull the connecting rod 106. At this time, the connection between the connecting rod 106 and the vertical rod 85 will move along with the driven rack 84, and the other end of the connecting rod 106 will pull the tension rod 105. The tension rod 105 will rotate along the support seat 103 when pulled. The rotation of the tension rod 105 will drive the round rod 102 to rotate, and the rotation of the round rod 102 will drive the blocking ring 104 to rotate. At this time, the two blocking rings 104 will open when they rotate at the same time. At this time, the rotating disk 3 and the lever groove 4 are exposed, which is convenient for the staff to adjust the rotating disk 3.
