[0002] In the production of steering wheel frames, die casting machines play a vital role, which can quickly inject molten aluminum and magnesium into the mold and quickly solidify the metal through high pressure. This step is the core of steering wheel frame production, ensuring that the shape and size of the frame meet the design requirements.

[0065] Please refer to Figure 6 and Figure 7The mounting frame 68 includes a base plate 681, a first mounting frame 682 and a second mounting frame 683. The bottom surface of the base plate 681 is fixedly connected to the round frame 42. The bottom ends of the first mounting frame 682 and the second mounting frame 683 are fixedly mounted on the base plate 681. The outer side of the push cylinder 661 is fixedly connected to the first mounting frame 682. The outer side of the rotating rod 671 is rotatably connected to the second mounting frame 683, so that the push cylinder 661 and the rotating rod 671 can be firmly installed and supported for convenient and stable use to meet the needs during use.

[0066] For further information, please refer to Figure 2 The transmission assembly 7 includes a driven wheel 71, a driving wheel 72, a motor 73, a pipe seat 74 and a through groove 75. The bottom end of the driven wheel 71 is fixedly connected to the column 52, the driven wheel 71 and the column 52 are kept coaxially matched, the outer side of the driving wheel 72 is meshed with the driven wheel 71, the output shaft of the motor 73 is fixed to the driving wheel 72, and the motor 73 is fixedly mounted on the outer side of the mounting seat 31, so that the driving wheel 72 is driven by the motor 73 to rotate, and the driven wheel 71 can be forced to rotate synchronously, the bottom end of the pipe seat 74 is coaxially fixed to the driven wheel 71, and the top of the pipe seat 74 is bolted to the infusion tube 1, so that when the infusion tube 1 needs to be loaded and unloaded, it can be separated from the pipe seat 74 by the loading and unloading bolts, thereby improving the loading and unloading efficiency, so that the pipe seat 74 can drive the infusion tube 1 to rotate after following the rotation of the driving wheel 71, and a through groove 75 is opened on the surface of the driven wheel 71, through which it is convenient for workers to lubricate the lubrication port 615, thereby improving the operating space and convenience.

[0067] For further information, please refer to Figure 8 The detection assembly 8 includes a synchronization rod 81, a detector 82 and a frame 83. The top of the synchronization rod 81 is coaxially fixed with the mounting frame 44, so that when the mounting frame 44 rotates, the synchronization rod 81 can be driven to rotate. The detector 82 is installed on the outside of the synchronization rod 81 to detect the rotation angle of the synchronization rod 81. The type of the detector 82 is an angle encoder. The angle encoder is an existing mature component and can be customized according to needs during implementation, so it will not be described in detail here.

[0068] The outer end of the frame 83 is fixed to the mounting base 31, and the bottom end of the detector 82 is fixed on the frame 83. The middle part of the frame 83 is a through-hole. The bottom end of the synchronization rod 81 passes through the frame 83 through the empty slot from the bottom end of the detector 82. The rotation angle of the synchronization rod 81 is detected by the detector 82 to obtain the rotation angle of the infusion tube 1. Before implementation, the rotation angle of the infusion tube 1 when it moves into the feed port and the angle when it is reset and idle can be measured first, so that the detector 82 can obtain the information of whether the tube mouth of the infusion tube 1 is at the feed port or has been reset and moved out by referring to the above angles, and send it to the controller in the production system, so that when the worker operates the infusion tube 1 to rotate, it can provide him with a rotation angle prompt, which is convenient for the worker to judge whether the infusion tube 1 is in the initial position or the feed port position, reducing the risk of judgment error of the worker.

[0069] Furthermore, in order to further improve the safety, the opening and closing component 9 includes an output component and a switch seat. The output component is fixedly connected to the bottom end of the synchronization rod 81, the switch seat is fixedly arranged on the inner wall of the mounting seat 31, and the outer end of the output component is connected to the switch seat. The opening and closing of the switch on the switch seat is controlled by the output component, so that when the infusion tube 1 is reset, the output component operates the switch seat so that the valve component 23 can be automatically closed, and after the infusion tube 1 is aligned with the feed port, the valve component 23 is opened.

[0070] Specifically, the output assembly includes a fixed frame 91, a movable frame 92, a guide rod 93, a first gear 94, a second gear 95, a connecting frame 96, a driving frame 97 and an opening and closing frame 98. The outer side of the fixed frame 91 is fixed to the mounting seat 31, and the movable frame 92 is arranged at intervals on the outer side of the fixed frame 91. One end of the guide rod 93 is fixed to the fixed frame 91, and the other end is fixed to the inner wall of the mounting seat 31. The movable frame 92 slides along the guide rod 93, so that the movable frame 92 can move closer to or away from the fixed frame 91 along the guide rod 93. The structure of the movable frame 92 is the same as that of the fixed frame 91.

[0071] The first gear 94 and the second gear 95 mesh with each other, and the first gear 94 and the second gear 95 are both located inside the fixed frame 91 and the movable frame 92. The centers of the first gear 94 and the second gear 95 are both rotatably matched with the connecting frame 96. A connecting rod 961 is rotatably mounted on the connecting frame 96. The centers of the first gear 94 and the second gear 95 are both fixed with the connecting rod 961.

[0072] The outer side of the synchronization rod 81 is in rotational contact with the fixed frame 91, and the number of drive frames 97 is set at two places. The first gear 94 is fixed to the bottom end of the synchronization rod 81 through the drive frame 97, so that the bottom end of the synchronization rod 81 is fixed to the drive frame 97 after passing through the fixed frame 91. When the synchronization rod 81 rotates counterclockwise, it will drive the drive frame 97 to rotate synchronously. The drive frame 97 is rotatably connected with the connecting rod 961 on the first gear 94, so that after the drive frame 97 rotates counterclockwise, it can drive the first gear 94 to be thrust, so that the first gear 94 is displaced along the circumferential trajectory of the drive frame 97, and drives the second gear 95 to rotate;

[0073] When the mounting base 1 is fixedly mounted on the placement surface, the infusion tube 1 is aligned with the feed port after being rotated counterclockwise, so that the rotation direction of the infusion tube 1 is synchronized with the displacement of the first gear 94 .

[0074] The second gear 95 is rotated and matched with the moving frame 92 through the driving frame 97. The connecting frame 961 on the second gear 95 is fixed to the driving frame 97. When the second gear 95 rotates, it drives the driving frame 97 to rotate clockwise, and drives the moving frame 92 to approach the fixed frame 91 through the driving frame 97. When the synchronization rod 81 rotates and resets, the moving frame 92 is reset, and so on.

[0075] The opening and closing frame 98 is fixedly arranged on the outside of the moving frame 92. The switch seat includes a shell 99, a guide groove 910 and a contact switch 911. The shell 99 is fixedly connected to the inner wall of the mounting seat 31. A guide groove 910 is provided on the side of the shell 99 close to the opening and closing frame 98. Two contact switches 911 are fixedly arranged on the inner wall of the guide groove 910 at symmetrical positions. The opening and closing frame 98 contacts the contact switches 911 after sliding along the guide groove 910. The contact switches 911 are respectively arranged at the initial end and the end end of the movement of the opening and closing frame 98. When the valve assembly 23 is closed, the opening and closing frame 98 is in contact with the first contact switch 911. The switch is a closed switch. When the synchronization rod 81 rotates counterclockwise, that is, the infusion tube 1 rotates counterclockwise, the moving frame 92 drives the opening and closing frame 98 to move toward another contact switch 91. The contact switch 91 is the opening switch of the valve assembly 23. When the infusion tube 1 is aligned with the feed port, the opening and closing frame 98 just contacts the contact switch 91, so that the valve assembly 23 is automatically opened. Therefore, even if the worker accidentally opens the infusion switch after rotating the infusion tube 1, if the infusion tube 1 is not aligned with the feed port, the aluminum-magnesium liquid can be intercepted by the valve assembly 23, thereby improving the safety performance.

[0076] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0077] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
