Description

Technical Field

[0001] The present invention belongs to the technical field of wire laying machines, and in particular relates to a wire laying unit that is compatible with both thermoplastic and thermosetting materials. Background Art

[0002] With the continuous development of technology, large aircraft and large spacecraft are widely adopting lightweight design to obtain a greater thrust-to-weight ratio and improve load-carrying capacity. In addition, the requirements for structural strength are constantly increasing. Ensuring strength while reducing mass has become the core issue of lightweight design. Carbon fiber placement molding technology is one of the best ways to solve this problem. Automatic fiber placement technology has changed the traditional manufacturing process and increased the manufacturing speed of composite components. It has the characteristics of stable placement accuracy, reliable quality, small and uniform fiber bundle gaps, and can adapt to the placement of complex curved surfaces in space.

[0003] Fiber placement technology is one of the important means to achieve "low-cost" manufacturing of composite materials. It combines the respective advantages of fiber winding technology and automatic tape laying technology. Through a placement head that can complete the functions of tow clamping, re-feeding and cutting, the prepreg tow is placed on the surface of the product at a certain angle. It is mainly used for the automatic forming and processing of carbon fiber for complex parts such as large aerospace spherical crown components, vertebral components, load-bearing cylinder components, wall panel components, S-type air inlets, large aircraft fuselages, etc.

[0004] When the wire laying unit in the prior art is in use, the wire laying head is mostly fixedly installed. When it is necessary to switch between thermoplastic and thermosetting materials for laying and winding, it is not possible to switch flexibly. Different wire laying units need to be replaced to switch between laying and winding different materials. This is not only inefficient and affects the progress of wire laying, but also increases the workload and is not convenient for long-term use.

[0005] The information disclosed in this background section is only intended to enhance understanding of the overall background of the invention and should not be considered as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

The wire laying replacement mechanism 2 includes a wire laying replacement positioning plate 201, which can position the position of the wire laying head mounting tubes 102 to improve the stability of the wire laying head mounting tubes 102.

[0051] A wire placement replacement positioning chamber 202 is provided on the upper side of the wire placement replacement positioning plate 201 , which is connected to the wire placement unit body 1 , so that the wire placement connecting pipe 103 can be connected to the wire placement replacement positioning chamber 202 through the wire placement unit body 1 .

[0052] In addition, a wire placement replacement mounting ring 203 is rotatably installed on the outer side of the wire placement replacement positioning chamber 202, which can drive the displacement of the wire placement replacement positioning plate 201 through the wire placement electric telescopic rod 204. A pair of wire placement electric telescopic rods 204 are fixedly installed between the wire placement replacement mounting ring 203 and the wire placement replacement positioning plate 201, which can be automatically retracted and extended, and can be extended when the wire placement replacement positioning plate 201 rotates, and retracted after the wire placement head mounting tube 102 is aligned.

[0053] like Figures 1 to 8 As shown, the placement head mounting tube 102 is arranged to pass through the placement head replacement positioning plate 201, which facilitates the installation of the placement head mounting tube 102, improves the stability of the placement head mounting tube 102, and reduces the probability of the placement head mounting tube 102 tilting.

[0054] Among them, a wire placement head replacement positioning ring 205 is fixedly installed on the outer side of the wire placement head mounting tube 102, which improves the stability of the wire placement head mounting tube 102, further reduces the possibility of the wire placement head mounting tube 102 being separated from the wire placement head replacement positioning plate 201, and makes it more convenient to fix the connection between the wire placement head mounting tube 102 and the wire placement head, so that the stability of the wire placement head is further improved.

[0055] In addition, a positioning groove matching the wire placement replacement positioning ring 205 is bored on the wire placement replacement positioning plate 201, which facilitates the positioning of the wire placement replacement positioning ring 205 and ensures that the position of the wire placement head mounting tube 102 does not change.

[0056] like Figures 1 to 8 As shown, a pair of wire placement replacement balancing rods 206 are fixedly installed on the wire placement replacement positioning plate 201, which effectively improves the balance of the wire placement replacement positioning plate 201, reduces the probability of the wire placement replacement positioning plate 201 tilting, and makes the lifting and lowering of the wire placement replacement positioning plate 201 better maintained in balance.

[0057] In addition, a wire placement replacement mounting plate 207 is slidably installed on the outside of the wire placement replacement balance rod 206. The wire placement replacement mounting plate 207 is fixedly installed with the wire placement replacement mounting ring 203, which effectively improves the balance of the wire placement replacement balance rod 206.

[0058] like Figures 1 to 5As shown, a wire placement replacement torsion ring 208 is fixedly installed on the wire placement replacement positioning chamber 202, which can locate the position of the wire placement replacement installation ring 203 and provide corresponding guidance for the rotation of the wire placement replacement installation ring 203.

[0059] In addition, a torsion groove matching the wire placement replacement torsion ring 208 is bored on the wire placement replacement installation ring 203, which facilitates the rotation of the wire placement replacement installation ring 203 and provides corresponding space for the installation of the wire placement replacement positioning chamber 202.

[0060] like Figures 1 to 6 As shown, a number of evenly distributed wire placement replacement friction balls 209 are installed between the wire placement replacement torsion ring 208 and the wire placement replacement mounting ring 203, which reduces the friction between the wire placement replacement torsion ring 208 and the wire placement replacement mounting ring 203, so that the rotation of the wire placement replacement mounting ring 203 can be less affected.

[0061] Among them, a friction groove matching the wire placement replacement friction ball 209 is carved on the wire placement replacement torsion ring 208, which can position the rotation of the wire placement replacement friction ball 209 so that the rotation of the wire placement replacement friction ball 209 will not separate from the wire placement replacement torsion ring 208, making the wire placement replacement friction ball 209 more stable.

[0066] like Figures 1 to 6 As shown, a positioning and sealing mechanism 3 is slidably installed on the wire laying head mounting tube 102, which is used to seal the wire laying head mounting tube 102. The positioning and sealing mechanism 3 includes a positioning and sealing lifting ring 301, which can slide in the wire laying head mounting tube 102 and squeeze the positioning and sealing ring 304 through the limitation of the wire laying head mounting tube 102.

[0067] Among them, several evenly distributed positioning and closing springs 302 are installed between the positioning and closing lifting ring 301 and the wire laying head installation tube 102, which can squeeze the positioning and closing lifting ring 301 so that the positioning and closing lifting ring 301 can better squeeze the positioning and closing sealing ring 304.

[0068] In addition, a pair of positioning closed compression rings 303 are fixedly installed on the lower side of the wire placement replacement positioning chamber 202, which can cooperate with the positioning closed spring 302 to enable the positioning closed sealing ring 304 to seal the wire placement head installation tube 102, so that the wire placement head installation tube 102 will not leak after switching.

[0069] like Figures 1 to 8 As shown, a positioning closed sealing ring 304 is installed between the positioning closed lifting ring 301 and the positioning closed compression ring 303, which improves the sealing performance of the positioning closed lifting ring 301 and the positioning closed compression ring 303. A positioning closed mounting frame 305 is fixedly installed in the wire laying head mounting tube 102, which can provide corresponding support for the positioning closed telescopic rod 306, so that the positioning closed telescopic rod 306 can better support the extrusion closed compression plate 403.

[0070] In addition, a positioning and sealing telescopic rod 306 is fixedly installed on the positioning and sealing mounting frame 305, which can squeeze the extrusion and sealing compression plate 403 so that the extrusion and sealing compression plate 403 no longer closes the wire placement replacement positioning chamber 202.

[0071] like Figures 1 to 4 As shown, an extrusion sealing mechanism 4 is fixedly installed in the wire placement replacement positioning plate 201, which is used to seal the wire placement replacement positioning chamber 202. The extrusion sealing mechanism 4 includes an extrusion sealing mounting frame 401, which facilitates the installation of the extrusion sealing balance rod 402 and provides corresponding support for the installation of the extrusion sealing balance rod 402.

[0072] Among them, multiple pairs of extrusion-sealed balance rods 402 are fixedly installed on the lower side of the extrusion-sealed mounting frame 401, which can support the installation of the extrusion-sealed compression plate 403 and provide corresponding balance for the sliding of the extrusion-sealed compression plate 403.
