Description

Technical Field

[0001] The utility model relates to the technical field of knuckle die processing, and particularly relates to a knuckle die tooling fixture. Background Technique

[0002] The knuckle, also known as the "sheep's horn", is one of the important parts in the automotive steering axle. It can enable the vehicle to drive stably and transmit the driving direction sensitively. The function of the knuckle is to transmit and bear the load at the front of the vehicle, support and drive the front wheels to rotate around the kingpin to make the vehicle turn. Under the driving state of the vehicle, it bears variable impact loads. Molds are required for manufacturing the knuckle, and processing machines such as numerical control machine tools and milling machines are required during mold production.

[0003] Since there are grooves in the knuckle die, there will be debris on the inner side of the mold groove during milling processing. The debris will affect the machining accuracy and quality of the mold. Currently, the commonly used method is for workers to manually clean the debris on the inner side of the mold groove with brushes of different sizes. This method requires shutdown cleaning, which affects the processing efficiency. At the same time, the debris on the inner side of the mold groove cannot be cleaned in real time, which will also lead to a decrease in the cleaning efficiency. Therefore, a knuckle die tooling fixture is proposed for the above problems. Summary of the Utility Model

A first screw rod 3 is spirally connected inside the first fixing plate 2. One end of the first screw rod 3 is fixedly connected to a handwheel 5, and the other end of the first screw rod 3 is rotatably connected to a clamping plate 4. One end of the clamping plate 4 clamps a mold 6. Under the action of the first screw rod 3 and the clamping plate 4, the clamping and fixing of the mold 6 can be realized, ensuring the stability of the mold 6 during processing. The mold 6 is placed on the top end of the base 1. A second fixing plate 7 is fixedly connected to the top end of the base 1. A moving mechanism is fixedly connected to one end of the second fixing plate 7. One end of the moving mechanism is fixedly connected to a support plate 12. An electric telescopic rod 13 is fixedly connected inside the support plate 12. The top end of the electric telescopic rod 13 is fixedly connected to a load-bearing plate 14. A swinging mechanism is fixedly connected to one end of the load-bearing plate 14. One end of the swinging mechanism is fixedly connected to a nozzle 17. One end of the nozzle 17 is communicated with an air inlet pipe 18, and the air inlet pipe 18 is communicated with a high-pressure air source. The high-pressure air source can introduce high-pressure gas into the inside of the nozzle 17 through the air inlet pipe 18, and the debris inside the groove of the mold 6 can be cleaned by the high-pressure gas. Moreover, the working height of the nozzle 17 can be adjusted by the electric telescopic rod 13, improving the working range of the nozzle 17.

[0024] As a further improvement of the present invention, as Figure 1 and Figure 2 shown, the moving mechanism includes a first motor 10 fixedly connected to the second fixing plate 7. The end of the main shaft of the first motor 10 is fixedly connected to a second screw rod 8. A slider 11 is spirally connected to the outside of the second screw rod 8. The slider 11 is fixedly connected to the support plate 12. During the milling process of the mold 6 by the machine tool, under the action of the slider 11, the nozzle 17 reciprocates on one side of the mold 6. The debris inside the groove of the mold 6 can be blown out by the high-pressure gas ejected from the nozzle 17, thereby preventing the debris from affecting the processing quality and accuracy of the mold 6 inside the groove. Moreover, through the nozzle 17, it can ensure that the debris inside the groove of the mold 6 is cleaned while milling, thereby improving the cleaning efficiency, and there is no need to stop the machine for manual cleaning, also improving the overall processing efficiency of the mold 6.

[0025] As a further improvement of the present invention, as Figure 1 and Figure 2 shown, a guide shaft 9 is slidably connected inside the slider 11, and the guide shaft 9 is fixedly connected to the second fixing plate 7. The normal movement of the slider 11 can be ensured through the guide shaft 9.

[0026] As a further improvement of the present invention, as Figure 1 、 Figure 2And Figure 3 As shown, the swing mechanism includes a connecting cover 19 fixedly connected to the load plate 14. A second motor 20 is fixedly connected to the inner side of the connecting cover 19. The end of the main shaft of the second motor 20 is fixedly connected to a turntable 21. One end of the turntable 21 is rotatably connected to a push rod 22. The other end of the push rod 22 is rotatably connected to a connecting rod 16. The other end of the connecting rod 16 is fixedly connected to the nozzle 17. One end of the connecting rod 16 is rotatably connected to a support column 15, and the support column 15 is fixedly connected to the load plate 14. Under the interaction of the second motor 20 and the turntable 21, the connecting rod 16 can drive the nozzle 17 to swing in the vertical direction, thereby increasing the cleaning range of the nozzle 17 and ensuring that the debris inside the grooves at different positions on the surface of the mold 6 can be cleaned up.

[0027] As a further improvement of the present utility model, as Figure 1 shown, a protective cloth 23 is fixedly connected to the outer side of one end of the connecting rod 16. The four sides of the protective cloth 23 are fixedly connected to the connecting cover 19. The protective cloth 23 can ensure that debris will not enter the inner side of the connecting cover 19 and prevent the debris from affecting the movement of the turntable 21 driving the push rod 21.

[0028] As a further improvement of the present utility model, as Figure 1 shown, the protective cloth 23 is made of elastic rubber to ensure that the protective cloth 23 will not affect the swing of the connecting rod 16.

[0029] Working process: When the mold 6 is milled by the machine tool, the first motor 10 drives the second screw rod 8 to rotate spirally inside the slider 11, so that the slider 11 drives the nozzle 17 to reciprocate on one side of the mold 6 through the support plate 12, the load plate 14 and the swing mechanism. At the same time, the second motor 20 will also drive the connecting rod 16 and the nozzle 17 to reciprocate and swing in the vertical direction through the turntable 21 and the push rod 22, so as to blow out the debris inside the grooves of the mold 6 by the high-pressure gas ejected from the nozzle 17, thereby preventing the debris from affecting the processing quality and accuracy of the mold 6 inside the grooves. And through the nozzle 17, it can ensure that the debris inside the grooves of the mold 6 is cleaned while milling, thereby improving the cleaning efficiency, and there is no need to stop the machine for manual cleaning, which also improves the overall processing efficiency of the mold 6.
