Description

Technical Field

[0001] This utility model relates to the field of CNC lathe technology, and in particular to a CNC lathe cutting auxiliary device for processing carbon tubes with a four-axis machine arm. Background Technology

[0002] The carbon fiber tube for a four-axis drone arm is a tubular structure made of carbon fiber and is a core component of the drone arm. The carbon fiber tube for a four-axis drone arm requires CNC lathe cutting during processing, and the following auxiliary mechanisms are needed during the cutting process:

[0003] 1. Clamping and fixing structure: used to fix the carbon tube of the four-axis cutting arm to ensure that the carbon tube will not be displaced or shaken during the cutting process;

[0004] 2. Cooling structure: The cooling structure effectively avoids the physicochemical changes of carbon fiber caused by high temperature by spraying cutting fluid or compressed air, ensuring that the key performance indicators such as the strength and stiffness of the carbon tube are not affected.

[0005] 3. Protective shield: Effectively isolates the cutting area from the operator to prevent flying debris from injuring people or entering the operator's respiratory tract, thus reducing occupational health risks.

[0006] The cutting parameters of CNC lathes are usually set based on the original length of carbon tubes under standard conditions. When the initial lengths of a batch of carbon tubes are not uniform, the same parameter settings will cause the actual cutting starting point of each carbon tube to deviate from the standard reference point. The deviation will cause the length tolerance of the same batch of products to exceed the design requirements, thereby destroying the consistency of the products. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a CNC lathe cutting auxiliary device for carbon tube processing with a four-axis machine arm. It solves the technical problem that the cutting parameters of CNC lathes are usually set based on the original length of carbon tubes under standard conditions. When the initial lengths of a batch of carbon tubes are not uniform, the same parameter settings will cause the actual cutting starting point of each carbon tube to deviate from the standard reference point. The deviation causes the length tolerance of the same batch of products to exceed the design requirements, thereby destroying the consistency of the products.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A CNC lathe cutting auxiliary device for machining carbon tubes with a four-axis machine arm includes a lathe body. Inside the lathe body is a measuring mechanism for measuring the length of the carbon tubes in the four-axis machine arm. The measuring mechanism includes a measuring plate, adjusting grooves, and adjusting blocks. The measuring plate is located inside the lathe body. Several adjusting grooves are formed on the upper surface of the measuring plate. The adjusting blocks are engaged inside the adjusting grooves. A storage mechanism for placing the measuring plate is provided on the side of the lathe body corresponding to the measuring plate. The storage mechanism includes a storage slot, a rotating shaft, and a baffle. The storage slot is located inside the lathe body. The rotating shaft is rotatably connected inside the storage slot. The measuring plate is fixedly installed outside the rotating shaft. The baffle is slidably connected to the end of the storage slot away from the rotating shaft and is used to restrict the rotation of the measuring plate.

[0010] Preferably, the measuring plate has through holes on one side corresponding to each adjustment slot, and a screw is fixedly installed at the lower end of the adjustment block. The screw is slidably connected inside the through hole, and a limit rod is connected to the external thread of the screw.

[0011] Preferably, the storage slot has a movable slot inside, the baffle is slidably connected inside the movable slot, and a spring for supporting the baffle is fixedly connected inside the movable slot.

[0012] Preferably, a limiting block for limiting the range of movement of the baffle is fixedly installed on the side of the lathe body near the baffle, and a handle is fixedly installed on the outside of the baffle.

[0013] Preferably, the measuring plate is provided with limiting springs at both ends near the rotating shaft to limit the rotation of the measuring plate, and slots are provided at both ends inside the receiving groove. The end of the limiting spring is slidably connected to the inside of the slot. Deformation grooves are provided at both ends of the measuring plate. One end of the limiting spring is fixedly connected to the inside of the deformation groove, and the other end extends outward.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The vertical edge of the measuring plate provides an axial positioning point for the carbon tube. The operator can insert the adjustment block into the corresponding adjustment groove according to the standard length of the carbon tube. The distance between the end face of the measuring plate and the vertical edge of the measuring plate constitutes the standard range for measuring the length of the carbon tube. This is used to determine whether the carbon tube meets the cutting length requirements. Therefore, carbon tubes with excessive length can be screened out and removed before cutting to avoid inconsistent product lengths after cutting due to inconsistent initial lengths of the carbon tubes, thereby ensuring the consistency of the product after carbon tube cutting.

[0016] 2. When the measuring plate is unfolded to the working state, the end of the limiting spring clip is engaged in the slot, restricting the rotation of the measuring plate and keeping it in a stable working position. This makes it easier for the operator to measure the carbon tube using the measuring mechanism, thus improving the ease of operation. Attached Figure Description

[0026] This application provides a CNC lathe cutting auxiliary device for carbon tube processing with a four-axis machine arm. It effectively solves the technical problem that the cutting parameters of CNC lathes are usually set based on the original length of carbon tubes under standard conditions. When the initial lengths of a batch of carbon tubes are not uniform, the same parameter settings will cause the actual cutting starting point of each carbon tube to deviate from the standard reference point. The deviation causes the length tolerance of the same batch of products to exceed the design requirements, thereby destroying the consistency of the products.

[0027] Example

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the technical solution in this application embodiment effectively solves the technical problem that the cutting parameters of CNC lathes are usually set based on the original length of carbon tubes under standard conditions. When the initial lengths of a batch of carbon tubes are inconsistent, the same parameter setting will cause the actual cutting starting point of each carbon tube to deviate from the standard reference point. This deviation causes the length tolerance of the same batch of products to exceed the design requirements, thereby compromising product consistency. The overall idea is as follows:

[0029] To address the problems existing in the prior art, this utility model provides a CNC lathe cutting auxiliary device for processing carbon tubes with a four-axis machine arm. It includes a lathe body 1, and a measuring mechanism for measuring the length of carbon tubes in the four-axis machine arm is provided inside the lathe body 1. The measuring mechanism includes a measuring plate 2, an adjusting groove 3, and an adjusting block 4. The measuring plate 2 is located inside the lathe body 1 and is L-shaped. There are several adjusting grooves 3, all of which are formed on the upper surface of the measuring plate 2. The adjusting block 4 is engaged inside the adjusting groove 3.

[0030] The vertical edge of the measuring plate 2 provides an axial positioning point for the carbon tube. The adjustment grooves 3 at different positions correspond to different measurement lengths, enabling adaptive measurement of carbon tubes of various specifications. The operator can insert the adjustment block 4 into the corresponding adjustment groove 3 according to the standard length of the carbon tube. The distance between the end face of the measuring plate 2 and the vertical edge of the measuring plate 2 constitutes the standard range for measuring the length of the carbon tube, which is used to determine whether the carbon tube meets the cutting length requirements.

[0031] The lathe body 1 has a storage mechanism for placing the measuring plate 2 on one side. The storage mechanism includes a storage slot 5, a rotating shaft 6, and a baffle 7. The storage slot 5 is opened inside the lathe body 1. The rotating shaft 6 is rotatably connected inside the storage slot 5. The measuring plate 2 is fixedly installed outside the rotating shaft 6. The baffle 7 is slidably connected to the end of the storage slot 5 away from the rotating shaft 6 and is used to restrict the rotation of the measuring plate 2.

[0032] The storage slot 5 provides storage space for the measuring plate 2. When the measuring mechanism is not in use, the measuring plate 2 can be stored away. The rotating shaft 6 enables the measuring plate 2 to rotate around it, realizing the conversion between the working state and the storage state of the measuring plate 2.

[0033] Each side of the measuring plate 2 corresponding to each adjustment groove 3 has a through hole 8, which communicates with the interior of the adjustment groove 3. A screw 9 is fixedly installed at the lower end of the adjustment block 4. The screw 9 is slidably connected inside the through hole 8. A limit rod 10 is threadedly connected to the outside of the screw 9. The limit rod 10 consists of a threaded sleeve and cuboid plates on both sides. After the screw 9 passes through the through hole 8, the limit rod 10 is rotated to make it fit against the surface of the measuring plate 2, thereby fixing the adjustment block 4 in the adjustment groove 3 and preventing it from loosening or shifting.

[0034] The storage slot 5 has a movable slot 11 inside. The baffle 7 is slidably connected inside the movable slot 11. A spring 12 for supporting the baffle 7 is fixedly connected inside the movable slot 11. A limiting block 13 for limiting the movement range of the baffle 7 is fixedly installed on the side of the lathe body 1 near the baffle 7. A handle 14 is fixedly installed on the outside of the baffle 7. The handle 14 is attached to the upper surface of the limiting block 13. The movable slot 11 provides guidance and space for the sliding of the baffle 7. The spring 12 provides elastic force. When the operator releases the handle 14, the spring 12 resets and pushes the baffle 7 to move, so that it automatically resets and limits the rotation of the measuring plate 2. The limiting block 13 limits the movement range of the baffle 7 and prevents the baffle 7 from moving excessively and falling out of the movable slot 11.

[0035] Both ends of the measuring plate 2 near the rotating shaft 6 are provided with limiting spring pieces 15 to restrict the rotation of the measuring plate 2. Both ends of the receiving groove 5 are provided with slots 16. The ends of the limiting spring pieces 15 are slidably connected to the inside of the slots 16. Both ends of the measuring plate 2 are provided with deformation grooves 17. One end of the limiting spring piece 15 is fixedly connected to the inside of the deformation groove 17, and the other end extends outward. When the measuring plate 2 is unfolded to the working state, the end of the limiting spring piece 15 is inserted into the slot 16 to restrict the rotation of the measuring plate 2 and keep the measuring plate 2 in a stable working position. The deformation groove 17 provides space for the deformation of the limiting spring piece 15.

[0036] Working principle:

[0037] The first step is to measure the length of the carbon tube. One end of the carbon tube is placed against the vertical edge of the measuring plate 2 for axial positioning. The operator inserts the adjusting block 4 into the corresponding adjusting groove 3 according to the standard length of the carbon tube. The screw 9 at the lower end of the adjusting block 4 passes through the through hole 8 of the measuring plate 2. By rotating the limiting rod 10, the adjusting block 4 is made to fit against the surface of the measuring plate 2, thereby fixing the adjusting block 4. At this time, the distance between the end face of the adjusting block 4 and the vertical edge of the measuring plate 2 is the length of the carbon tube. The carbon tube can be placed between the end face of the adjusting block 4 and the vertical edge of the measuring plate 2. If it fits perfectly, the carbon tube meets the cutting requirements. If it cannot fit or there is a gap, the carbon tube does not meet the cutting requirements.

[0038] The second step is to store the measuring plate 2 when the measuring mechanism is not in use. The operator pushes the handle 14 on the baffle 7 to overcome the spring force of the spring 12 and make the baffle 7 enter the interior of the moving groove 11. Press the limiting spring 15 to release the connection between the limiting spring 15 and the slot 16. At this time, the measuring plate 2 can rotate around the rotating shaft 6. The operator pushes the measuring plate 2 to gradually enter the storage groove 5. When the measuring plate 2 is completely in the storage groove 5, the handle 14 is released, the spring 12 resets and pushes the baffle 7 to reset. At this time, the baffle 7 restricts the rotation of the measuring plate 2, thus completing the storage and fixing of the measuring plate 2.

[0039] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
