[0002] Hot air cold riveting is a technique that uses hot air to uniformly heat the rivet post to a shaped state, and then connects two parts together by cold riveting. Hot air cold riveting welding is a low-cost and reliable welding method that can ensure the strong weld between the rotor impeller cover and the rotor body.

[0003] Existing process solutions mostly involve ultrasonic welding. This solution is difficult to adjust process parameters, which can easily cause cracks in the rotor body or indentations on the impeller cover surface. In addition, the operation is relatively cumbersome, which leads to a reduction in welding quality.

[0004] Therefore, a hot air cold riveting device for rotor impeller covers is proposed here. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0024] Please see Figures 1-3 This utility model provides a hot air cold riveting device for rotor impeller cover, including a base plate 100. A fixing screw block 110 is fixedly connected to the top of the base plate 100, and a slide cylinder 111 is fixedly connected between the outer sides of the fixing screw block 110. The model of the slide cylinder 111 is MXQ8-110.

[0025] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3A guide rail 120 is fixedly connected to the top of the base plate 100. A moving block 121 is slidably connected to the outer side of the guide rail 120. A mounting base 122 is fixedly connected to the top of the moving block 121. A part base 130 is mounted on the top of the mounting base 122. A vertical movement cylinder 140 is fixedly connected to the top of the base plate 100. The model of the vertical movement cylinder 140 is SDA40. A hot air equipment connecting plate 141 is fixedly connected to the end of the power output shaft of the vertical movement cylinder 140. A hot air head 142 is fixedly connected to the bottom of the hot air equipment connecting plate 141. The model of the hot air head 142 is 861DW. An L-shaped connecting block 112 is fixedly connected to the outer side of the sliding cylinder 111. The L-shaped connecting block 112 is fixedly connected to the moving block 121. Fixed components are fixedly connected to both sides of the top of the base plate 100. The fixed limit block 123 is aligned with the guide rail 120. By placing the part into the part base 130, the slide cylinder 111 is activated to move towards the hot air head 142. When the slide cylinder 111 moves, it drives the L-shaped connecting block 112 and the moving block 121 to move. The moving block 121 then moves the mounting base 122 and the part base 130 to below the hot air head 142. The hot air equipment is connected to the hot air head 142 via the hot air equipment connecting plate 141. The up-and-down cylinder 140 is activated to move the hot air head 142, so that the hot air head 142 fits against the part base 130 to heat the part. The temperature and air volume can be adjusted as needed. The equipment is easy to adjust and operate, and is suitable for most materials, thus improving its practicality.

[0026] For example, ultrasonic welding can easily cause cracks in the rotor body or indentations on the impeller cover surface during processing, resulting in reduced welding quality. By using the slide cylinder 111 to move the L-shaped connecting block 112 and the moving block 121, the part base 130 is moved to the area below the hot air head 142. The hot air head 142 heats the part to melt it. After melting, the slide cylinder 111 moves the part base 130 to the area below the cold riveting power source cylinder 211 for cold riveting welding. This method allows for control of temperature and airflow and is applicable to a wide range of materials.

[0027] Please refer to this carefully. Figure 1 , Figure 2 and Figure 4Mounting rods 200 are fixedly connected to the top two sides of the base plate 100. A mounting bracket plate 210 is fixedly connected to the top of the mounting rods 200. A cold riveting power source cylinder 211 (model SDA40) is fixedly connected to the top of the mounting bracket plate 210. The power output shaft of the cold riveting power source cylinder 211 passes through the mounting bracket plate 210. A positioning mounting cylinder 220 is fixedly connected to the inner side of the mounting bracket plate 210. A guide rod 221 is slidably connected to the inner side of the positioning mounting cylinder 220. A fixing plate 222 is fixedly connected to the end of the guide rod 221. The fixing plate 222 is connected to the cold riveting power source... The power output shaft of cylinder 211 is fixedly connected, and the bottom of the fixed plate 222 is fixedly connected to the cold riveting head 230. After heating and melting, the part base 130 is moved to the bottom of the cold riveting power source cylinder 211 by the slide cylinder 111. The cold riveting power source cylinder 211 is started to push the fixed plate 222 and the cold riveting head 230 to move, so that the cold riveting head 230 presses the part and performs riveting processing on the part. After welding, there are no ultrasonic welding scratches on the surface of the product and no product body breakage phenomenon. In particular, the bearing material inside the rotor body is better. At the same time, the dimensions of the welded product are easy to control, which improves the processing quality.

[0028] For example, ultrasonic welding can easily cause cracks in the rotor body or indentations on the impeller cover surface during processing. After the parts are heated and melted by the hot air head 142, the cold riveting power source cylinder 211 drives the cold riveting pressure head 230 to perform cold riveting stamping welding on the parts, so that the welded parts will not have cracks or indentations, thus improving the welding quality.

[0029] In use, the following steps are taken: First, the part is placed in the part base 130. Then, the sliding cylinder 111 is activated to move the sliding cylinder 111 towards the hot air head 142. When the sliding cylinder 111 moves, it drives the L-shaped connecting block 112 and the moving block 121 to move. The moving block 121 then moves the mounting base 122 and the part base 130 to below the hot air head 142. The hot air equipment is then connected to the hot air head 142 via the hot air equipment connecting plate 141. The up-and-down cylinder 140 is activated to move the hot air head 142, so that the hot air head 142 fits against the part base 130 to heat the part. The temperature and air volume can be adjusted as needed. The equipment is easy to adjust and operate, and it is suitable for most materials.

[0030] After the heating and melting are completed, the part base 130 is moved to the underside of the cold riveting power source cylinder 211 by the slide cylinder 111. The cold riveting power source cylinder 211 is activated to push the fixed plate 222 and the cold riveting head 230 to move, so that the cold riveting head 230 presses the part and performs riveting processing on the part. After welding, there are no ultrasonic welding scratches on the surface of the product and no product body breakage phenomenon. In particular, the bearing material inside the rotor body is easy to control. At the same time, the dimensions of the welded product are easy to control.

[0031] It should be noted that the slide cylinder 111, the up-and-down action cylinder 140, the hot air head 142, and the cold riveting power source cylinder 211 mentioned in the text are all existing technologies. The principle of the slide cylinder 111 is as follows: The slide cylinder 111 is an actuator that combines a cylinder and a slide mechanism. It mainly consists of a cylinder, a slide, and the mechanical structure connecting them. During operation, compressed air enters the cylinder, pushing the piston to move. The piston then drives the slider to move along the guide rail 120 through the connecting mechanism, thereby realizing the output of linear motion. The piston of the slide cylinder 111 is fixed on the piston rod, and the piston rod has plates at both ends that can be firmly fixed to the machine base. The slide moves back and forth on the piston rod. The principle of the up-and-down action cylinder 140 and the cold riveting power source cylinder 211 is that compressed air generates power inside the cylinder, pushing the piston rod to perform reciprocating linear motion. The principle of the hot air head 142 is that the hot air head 142 generates heat through a heating resistance wire (heating core). When the hot air head 142 is powered on, the blower blows air into the heater. The air passes through the spiral heating wire, which generates heat when powered on, and exchanges heat with the cold air, thus raising the temperature of the air at the outlet.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
