[0025] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0026] To achieve the above purpose, the present invention provides a simple jig for machining oblique holes in a carbon fiber tube. Figure 1-6As shown, the simple fixture includes a main clamping block 1, a first cover clamping block 2 and a second cover clamping block 3, and the two ends of the main clamping block 1 are detachably and tightly connected with a first cover clamping block 2 and a second cover clamping block 3. The first cover clamping block 2 and the second cover clamping block 3 are respectively covered on the two ends of the main clamping block 1 to form a tube body cavity 4. A first fixed clamping group is connected between the first cover clamping block 2 and the main clamping block 1, and a second fixed clamping group is connected between the second cover clamping block 3 and the main clamping block 1. The first cover clamping block 2 is provided with an upper oblique circular hole 5 with an inclined angle to its upper end face, and the main clamping block 1 is provided with a lower oblique circular hole 6 in the extension direction of the upper oblique circular hole 5. The upper oblique circular hole 5 and the corresponding lower oblique circular hole 6 are used for oblique hole processing of the carbon fiber tube body.
[0027] Traditionally, the processing of oblique holes in pipes relies on the experience of the machining technician, with slight offsets at a certain angle used as compensation. Other methods involve first machining with a simple fixture and then clamping. However, these methods often suffer from issues such as inaccurate processing, offsets, inconvenient clamping, and the inability to mass produce. The simple fixture used in this embodiment is specifically designed for the processing of oblique holes in carbon fiber pipes. It features easy disassembly, stable clamping, and fast operation. This allows for precise processing of oblique holes while also facilitating mass production, resulting in high production efficiency and significantly reduced processing costs.
[0028] Furthermore, the main clamping block 1 is provided with a tube body half groove 7, the first cover clamping block 2 is provided with a first half tube groove 8 on the inner side, and the second cover clamping block 3 is provided with a second half tube groove 9 on the inner side. The first half tube groove 8 and the second half tube groove 9 respectively form the two ends of the tube body through cavity 4 with the tube body half groove 7. Here, the carbon fiber tube body is placed in the tube body half groove 7, and then the first cover clamping block 2 and the second cover clamping block 3 are respectively covered, so that the carbon fiber tube body is tightened by the tube body through cavity 4. The carbon fiber tube body can be a single straight tube body, an arc-shaped tube body, a special-shaped tube body, etc. The main clamping block 1 can be processed by a CNC milling machine (CNC) according to the corresponding carbon fiber tube body to remove the corresponding tube body half groove 7 structure, as well as the upper oblique circular hole 5 and the lower oblique circular hole 6. The size of the carbon fiber tube body oblique hole to be processed is the same as the size of the upper oblique circular hole 5 and the lower oblique circular hole 6, thereby realizing the corresponding oblique hole processing.
[0029] Among them, the first fixed clamp group includes a first blind pin hole 10 and a positioning reference surface 11, the main clamping block 1 and the first cover clamping block 2 are aligned in parallel on the same side surface as the positioning reference surface 11, the upper surface of the main clamping block 1 and the lower surface of the first cover clamping block 2 are each provided with at least one corresponding first blind pin hole 10, the tube body half groove 7 is located on one side of the lower oblique circular hole 6 and is provided with at least one main limiting hole 12, the first cover clamping block 2 is provided with a plurality of first limiting holes located in the first half tube groove 8, and the first limiting holes correspond to the main limiting hole 12. In this way, each time a movable pin is pre-inserted into the first blind pin hole 10 of the main clamping block 1, the first cover clamping block 2 is inserted into the corresponding movable pin, and the carbon fiber tube body can be pressed. Moreover, by aligning the same side surface of the main clamping block 1 and the first cover clamping block 2 in parallel as the positioning reference surface 11, the reference surface and positioning can be quickly found, which can greatly save operation time and improve production efficiency for mass production operations. Of course, if disassembly is required, the first cover clamping block 2 can be directly removed by external force, and the carbon fiber tube body can be taken out, which is very convenient to operate.
[0030] Among them, the second fixing clamp group includes a second blind pin hole 13 and a second limiting hole 15, the second cover clamping block 3 is provided with a plurality of second limiting holes 15 located in the second half pipe groove 9, and the main clamping block 1 is provided with a plurality of main limiting holes 2 16 located in the tube body half groove 7, the second limiting holes 15 corresponding to the main limiting holes 2 16, and the upper surface of the main clamping block 1 and the lower surface of the second cover clamping block 3 are both provided with two corresponding second blind pin holes 13. Here, after the first cover clamping block 2 is clamped, the second cover clamping block 3 is clamped, that is, two movable pins are pre-placed in the second blind pin holes 13 of the main clamping block 1 each time, and the second cover clamping block 3 is inserted into the corresponding two movable pins to complete the compression of the carbon fiber tube body. When disassembling, the second cover clamping block 3 can be directly removed by external force, and the carbon fiber tube body can be taken out. The operation is very convenient, which can greatly save operation time and improve production efficiency for mass production operations.
[0031] Processing operation one:
[0032] 1. Obtain the main clamping block 1, the first cover clamping block 2, the second cover clamping block 3, and the carbon fiber tube body to be processed with an oblique hole;
[0033] 2. Place the carbon fiber tube into the tube half groove 7 of the main clamping block 1, and insert positioning pins into the main limiting hole 12 and the main limiting hole 2 16 to prevent the carbon fiber tube from rotating or moving forward and backward;
[0034] 3. Insert the movable pins into the first blind pin holes 10 and the second blind pin holes 13 at both ends of the main clamping block 1, and cover the first cover clamping block 2 and the second cover clamping block 3 respectively to compress the carbon fiber tube body. At this time, the clamping forms a whole, that is, a simple jig, and the following operation can be carried out.
[0035] Processing operation 2:
[0036] 1. Reference Figure 7-8 As shown, obtain an angle-adjustable universal vise, use the positioning reference surface 11 where the main clamping block 1 is located as a clamping surface of the universal vise to fix and clamp the main clamping block 1, and keep the upper surface of the main clamping block 1 horizontally parallel to the upper surface of the universal vise. At this time, one side of the first cover clamping block 2 is also aligned with the inner side surface of the universal vise;
[0037] 2. According to the angle formed by the inclined hole of the carbon fiber tube body relative to the positioning reference surface 11 of the main clamp 1, adjust the universal vise to the corresponding angle so that the inclined hole of the carbon fiber tube body is in a vertical state, which is convenient for the downward upright processing of the drilling machine. The inclined hole processing is converted into a straight hole downward processing through a simple fixture;
[0038] 3. After the processing is completed, directly remove the first cover clamp 2 and the second cover clamp 3 by external force, then remove the processed carbon fiber tube body, replace it with a new carbon fiber tube body to be processed, and repeat the above operation. After tightening the first cover clamp 2 and the second cover clamp 3, directly process.
[0039] In summary, the utility model provides a simple jig for processing oblique holes in carbon fiber tube bodies to form a tube body cavity 4 for clamping the carbon fiber tube body, and uses the first cover clamp 2 and the second cover clamp 3 to press, and uses the first limiting hole to correspond to the main limiting hole 12, and the second limiting hole 15 to correspond to the main limiting hole 2 16, so that the entire carbon fiber tube body is clamped firmly, and the simple fixture converts the oblique hole processing into straight hole downward processing, with precise processing, easy disassembly and clamping, and can be mass-produced with high efficiency and lower cost.
