Description

Technical Field

[0001] The present application relates to the technical field of composite material processing, and in particular to a composite material processing positioning device. Background Art

[0002] In the process of processing the carbon fiber preform, it is necessary to perform turning, slitting and hole-making processing on it. In order to facilitate the above processing, it is necessary to use a positioning device to position and fix it. Although the existing composite material processing positioning device can meet the basic needs of positioning and fixing the preform, it usually only supports and fixes the inner side of the preform, which can only meet the positioning and fixing needs of turning and hole-making processing of the preform. When the preform needs to be slit, especially when T-shaped or U-shaped structure slitting processing is required, only fixing the inner side of the preform can easily cause the preform to be over-supported and deformed during the slitting process, thereby affecting the subsequent processing of the preform and the final processing quality.

[0003] For example, the invention patent document with announcement number CN104924628B discloses a molding method, stacking tooling, curing mold and long-beam positioning device for an integral composite reinforced cylinder. In the technical solution of the patent document, the cylindrical composite material is positioned, supported and fixed by a positioning structure located inside the preform. Since it only has the function of supporting and fixing the preform, the preform will be subjected to an outward supporting force. When the preform is cut into longer sizes or T-shaped and U-shaped structures, it is easy to cause unbalanced force on the inner and outer sides of the preform, resulting in excessive external support of the preform, which in turn causes the preform to deform, thereby affecting the subsequent processing progress and the final processing quality. Summary of the invention

[0004] In view of this, the present application provides a composite material processing positioning device to solve the technical problem that in the prior art, during the turning, slitting and hole drilling processes of the composite material preform, only the inner side of the preform is supported and fixed, which causes the preform to be easily deformed and damaged during the slitting process because only the inner side is subjected to force, and affects the overall processing progress and processing effect.

[0005] In order to solve the above technical problems, the present application provides a composite material processing positioning device, including a central axis, fixed plates are respectively provided on both sides of the central axis, and multiple mounting plates are provided on the fixed plate, a first driving rod is rotatably provided on the inner end of the mounting plate, a support block for supporting the left and right sides of the end of the turning area of ​​the preform is rotatably provided on the other end of the first driving rod, a first balancing rod is rotatably provided between the outer end of the mounting plate and the outer end of the support block, a driving plate is slidably provided on the left side of the central axis, and driven plates located on the inner side of the fixed plate are also slidably provided on both sides of the central axis, a push rod that slides with the fixed plate and is connected through it is provided between the driving plate and the driven plate, and a Transmission rod, a push rod is rotatably provided between the first driving rod and the driven plate, a second driving rod is also rotatably provided at the outer end of the mounting plate, a locking module is also provided between the mounting plate and the second driving rod, the other end of the left second driving rod is rotatably provided with an auxiliary support frame capable of passing through the first axial slit, the two ends of the second balance rod are rotatably connected to the inner ends of the left mounting plate and the auxiliary support frame respectively, the front and rear ends of the auxiliary support frame are also rotatably provided with a pressing frame for pressing the left and right sides of the end of the turning area of ​​the preform, the connection between the auxiliary support frame and the pressing frame is locked by a locking pin shaft, and the other end of the right second driving rod is provided with a pressing block for pressing the right end of the preform.

A torsion spring is also sleeved on the rotating shaft, and both ends of the torsion spring are respectively connected to the second driving rod and the pawl.

[0014] By adopting the above technical solution, through the cooperation of the ratchet, the rotating shaft, the pawl and the torsion spring, the second driving rod can be effectively prevented from rotating autonomously, so that the auxiliary support frame is maintained in the adjusted position.

[0021] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects: 1. In the prior art, two positioning structures are usually used to position and fix the two ends of the preform respectively. Since the positioning processes on both sides are carried out separately, the line connecting the centers of the circles determined by the two positioning structures is not collinear with the axis of the preform, that is, there are problems of inaccurate centering and easy tilting of the preform to one side, which leads to the carbon cloth being easily misaligned due to eccentricity during the turning process of the preform, thereby affecting the strength of the preform; however, in the technical solution described in the present application, the two ends of the preform can be positioned and fixed simultaneously by means of positioning structures arranged at both ends of the same shaft structure, thereby effectively ensuring that the line connecting the centers of the circle of the positioning structures on both sides is collinear with the central axis of the preform, thereby ensuring the accuracy of centering and the accuracy of positioning and fixing, thereby ensuring the accuracy of turning.

[0022] 2. Since the first axial slit and the U-shaped slit at the left end of the preform are connected, the connection between the first axial slit and the U-shaped slit at the left end of the preform is prone to deformation. However, the technical solution described in the present application can support and fix the inner and outer sides of the connection between the first axial slit and the U-shaped slit at the left end of the preform, thereby effectively avoiding deformation of the preform at the connection between the first axial slit and the U-shaped slit during the slitting process on the left end of the preform.

[0023] 3. It can support the inner side of the second axial slit at the right end of the preform, and can also press and consolidate the outer side of the second axial slit at the right end of the preform. Therefore, it can effectively avoid deformation during the slitting process of the right end of the preform by fixing the directions inside and outside, thereby ensuring the stability and effect of the slitting process.

[0033] After the central axis 1 passes through the cylindrical preform 17, the push plate 21 can be rotated and adjusted, and the external thread 22 and the threaded connection hole are connected to make the push plate 21 slide left and right relative to the central axis 1. With the cooperation of the through hole, the push rod 9 and the transmission rod 10, the two driven plates 8 slide from left to right relative to the central axis 1, so that with the cooperation of the first driving rod 4, the first balance rod 6 and the push rod 11, the support blocks 5 on both sides are in contact with the inner side walls at both ends of the preform 17, so as to support and fix the left and right sides of the end of the preform 17 in the turning area 64, and then the locking module can be released from the second driving rod 12 and the mounting plate 3 on the left side.
