Description

Technical Field

[0001] This utility model relates to the field of air nozzle installation tooling technology, and in particular to a silicone tube air nozzle installation tooling. Background Technology

[0002] In automotive power, braking, and air conditioning systems, the installation of silicone tube gas nozzles must meet the requirements of "high-precision coaxiality, non-damaging sealing, and efficient batch assembly," otherwise it is easy to cause gas leakage and driving safety risks. However, there is currently a lack of dedicated tooling, and traditional installation methods have the following technical defects: 1. During manual installation, automotive silicone tubing is prone to elastic deformation, which can cause misalignment between the valve and the mounting hole. The valve sealing groove can easily scratch the inner wall of the silicone tubing, and leakage is likely to occur after the brake line valve is installed. General clamping tools cannot be adapted to non-circular tubing, which can cause the valve to be crooked, resulting in a low success rate of installation of small-diameter silicone tubing and miniature valves.

[0003] 2. The silicone tube and the air nozzle have an interference fit, which requires a stable thrust. Uneven manual force can easily tear the silicone tube, and the production efficiency is low. Summary of the Invention The technical problem this invention aims to solve is that inaccurate positioning during manual installation can easily damage the silicone tube and reduce production efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a silicone tube nozzle installation fixture, including an installation cylinder and a positioning ring coaxially fixedly connected to one side of the installation cylinder. A clamping plate for holding the silicone tube is radially slidably arranged on the inner side wall of the installation cylinder. The clamping plate is an arc-shaped plate and is evenly distributed around the installation axis. A heating structure is provided on the clamping plate.

[0005] Preferably, the inner layer of the clamping plate is provided with an air cavity, and both ends of the clamping plate are connected to air pipes, which are connected to an external high-temperature gas circulation system. The air cavity and the air pipes are in communication.

[0006] Preferably, an infrared thermometer is installed on the inner wall of the mounting cylinder, the infrared thermometer is positioned facing the clamping plate, and the infrared thermometer signal is connected to the high-temperature gas circulation system.

[0007] Preferably, a screw is rotatably connected to the middle of the clamping plate, the screw is threadedly connected to the mounting cylinder, the screw is radially distributed along the mounting cylinder, guide tubes are fixedly connected to both ends of the clamping plate, the guide tubes are parallel to the screw, the air pipe is connected to the guide tube, and the outer wall of the guide tube is provided with length graduations along the length direction.

[0008] Preferably, the movable end of the screw is fixedly connected to a rotating handle, and a heat insulation sleeve is provided on the rotating handle.

[0009] Preferably, the clamping plate is an arc-shaped plate.

[0010] Preferably, a connecting block is fixedly provided on the outer wall of the mounting cylinder, and the positioning ring is fixed on the connecting block by an L-shaped connecting rod. The connecting blocks are evenly distributed around the axis of the mounting cylinder.

[0011] Preferably, the bottom two sides of the mounting cylinder are fixedly connected with support legs, the bottom ends of the support legs are fixedly connected by rods, and the support legs and rods form a triangular structure.

[0012] This utility model provides a silicone tube air nozzle installation fixture, which has the following beneficial effects.

[0013] 1. The tooling is equipped with a positioning ring coaxial with the mounting cylinder, which allows for pre-coaxial calibration of the air nozzle, ensuring alignment between the air nozzle and the silicone tube mounting hole. This avoids coaxiality deviations caused by the elastic deformation of the silicone tube during manual installation. Simultaneously, the clamping plates inside the mounting cylinder are arc-shaped and evenly distributed around the cylinder's axis, providing stable clamping against the outer wall of the silicone tube. This avoids uneven localized force distribution common with general-purpose tools and prevents the air nozzle sealing groove from scratching the inner wall of the silicone tube. This design effectively solves the problems of "air nozzle misalignment and silicone tube damage" during air nozzle installation, and is particularly suitable for installing small-diameter silicone tubes and miniature air nozzles in automobiles, significantly improving the installation success rate.

[0014] 2. The tooling eliminates the need for manual adjustments to the positions of the air nozzle and silicone tube by using positioning rings and arc-shaped clamps for clamping and calibration, thus shortening the installation time per cycle. The heating structure of the clamps reduces insertion resistance, and the stable force applied by the screws reduces jamming and rework during installation. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments: Figure 1 This is a structural front view of an embodiment of the present utility model.

[0016] Figure 2 This is a structural side view of an embodiment of the present utility model.

[0018] like Figure 1 and Figure 2 As shown, this utility model provides a silicone tube nozzle installation fixture, including an installation cylinder 1 and a positioning ring 5 coaxially fixedly connected to one side of the installation cylinder 1. A clamping plate 9 for clamping the silicone tube is radially slidably arranged on the inner side wall of the installation cylinder 1. The clamping plate 9 is an arc-shaped plate and is evenly distributed around the axis of the installation shaft 1. A heating structure is provided on the clamping plate 9.

[0019] During the installation of the air nozzle, the air nozzle is positioned by the positioning ring 5, making the air nozzle coaxial with the mounting cylinder 1. Then, by adjusting the position of the clamping plate 9 inside the mounting cylinder 1, the silicone tube end inserted into the mounting cylinder 1 is clamped by the three clamping plates 9, ensuring that the silicone tube end is coaxial with the mounting cylinder, and thus making the silicone tube end coaxial with the air nozzle. Then, the heating structure is activated to heat the clamping plate 9, which heats the silicone tube end and pushes the air nozzle along the positioning ring 5, so that the air nozzle is accurately installed on the silicone tube end.

[0020] like Figure 1 and Figure 2 As shown. The inner layer of the clamping plate 9 is provided with an air chamber. Both ends of the clamping plate 9 are connected to air pipes 8, which in turn connect to an external high-temperature gas circulation system. The air chamber and air pipes 8 are in communication. The high-temperature gas circulation system heats the gas. After the gas temperature rises, it is transported through air pipes 8 to one end of the air chamber inside the clamping plate 9. After the gas heats the clamping plate 9, the air pipe 8 at the other end of the clamping plate 9 returns the gas to the high-temperature gas circulation system, reheating it for continued use. This raises the temperature of the clamping plate 9, softening the clamped silicone tube head to facilitate the installation of the air nozzle.

[0021] As a preferred embodiment of this utility model, an infrared thermometer is installed on the inner wall of the mounting cylinder 1, facing the clamping plate 9, and the infrared thermometer is connected to the high-temperature gas circulation system. The infrared thermometer detects the surface temperature of the clamping plate 9, and once the detected temperature reaches the set temperature, the high-temperature gas circulation system stops supplying gas to the clamping plate 9 to prevent the clamping plate 9 from overheating and damaging the silicone tube.

[0022] like Figure 1 and Figure 2 As shown. A screw 6 is rotatably connected to the middle of the clamping plate 9. The screw 6 is threadedly connected to the mounting cylinder 1 and is distributed radially along the mounting cylinder 1. Guide tubes 7 are fixedly connected to both ends of the clamping plate 9. The guide tubes 7 are parallel to the screw 6. The air pipe 8 is connected to the guide tube 7. The outer wall of the guide tube 7 has length markings along its length. When adjusting the position of the clamping plate 9, the screw 6 is rotated to move the clamping plate 9 relative to the axis of the mounting cylinder 1. The three clamping plates 9 inside the mounting cylinder 1 are used to position and clamp the head of the silicone tube. During the clamping process, it is necessary to ensure that the depth of each screw 6 inside the mounting cylinder 1 is equal. Under the action of the guide tubes 7, the head of the clamped silicone tube is made coaxial with the mounting cylinder 1. The depth of the screw 6 can be controlled by observing the length markings on the guide tube 7.

[0023] like Figure 1As shown, to facilitate the rotation of the screw 6 by the operator and to prevent heat from the clamping plate 9 from being transferred to the screw 6 and causing burns to the rotating handle, a rotating handle is fixedly connected to the movable end of the screw 6, and a heat-insulating sleeve is provided on the rotating handle.

[0024] In a preferred embodiment of this utility model, in order to increase the contact area between the clamping plate 9 and the silicone tube, and at the same time avoid damage caused by excessive compression of the silicone tube by the clamping plate 9, the clamping plate 9 is an arc-shaped plate.

[0025] like Figure 1 and Figure 2 As shown. A connecting block 3 is fixedly installed on the outer wall of the mounting cylinder 1. The positioning ring 5 is fixed to the connecting block 3 by an L-shaped connecting rod 4. The connecting blocks 3 are evenly distributed around the axis of the mounting cylinder 1. The positioning ring 5 is installed by six connecting rods 4 to ensure the stability of the installation.

[0026] As a preferred embodiment of this utility model, the bottom two sides of the mounting cylinder 1 are fixedly connected to support legs 2, and the bottom ends of the support legs 2 are fixedly connected by rods, forming a triangular structure with the support legs 2 and the rods. The triangular support structure formed by the two support legs and the rods provides horizontal support for the mounting cylinder 1, ensuring the stability of the mounting cylinder 1, and thus improving the stability of the air nozzle installation.
