Description

Technical Field

[0001] This utility model relates to the field of steering knuckle manufacturing technology, and in particular to a punching device for manufacturing aluminum alloy steering knuckles. Background Technology

[0002] The core function of the punching device for manufacturing aluminum alloy steering knuckles is to efficiently and accurately machine the required holes on the aluminum alloy steering knuckle blank to meet the assembly requirements of the automotive steering system. It punches complex hole shapes such as round holes, irregular holes, and stepped holes on the aluminum alloy steering knuckle for connecting components such as wheel hubs, suspension arms, and ball joints. Because there are many types of aluminum alloy steering knuckles and most of them are complex in shape, the existing devices cannot perform good clamping and fixing for complex aluminum alloy steering knuckles, resulting in a limited range of applications.

[0003] However, existing technologies, such as Chinese Publication No. CN221559500U, "A Punching Device for Manufacturing Aluminum Alloy Steering Knuckles," disclose a punching device for manufacturing aluminum alloy steering knuckles, relating to the field of aluminum alloy steering knuckle technology. This device includes a base plate, a frame fixedly connected to the outer wall of the base plate, a fixing block fixedly connected to the outer wall of the frame, a support column fixedly connected to the outer wall of the fixing block, a cylinder fixedly connected to the outer wall of the support column, and a punching device body fixedly connected to the outer wall of the cylinder. This invention, through the coordinated use of the base plate, frame, fixing block, support column, cylinder, punching device body, mounting plate, motor, work platform, and opening, facilitates the adjustment of the punching angle of the aluminum alloy steering knuckle during punching, resulting in good angle adjustment. Starting the motor causes the work platform to rotate and adjust, thereby achieving the function of adjusting the punching angle of the aluminum alloy steering knuckle.

[0004] However, this device lacks a non-standard clamping and fixing structure, making it unsuitable for aluminum alloy steering knuckles of different shapes and sizes. This leads to instability in clamping due to differences in workpiece shape. It cannot limit the steering knuckle from multiple directions, such as horizontal and vertical, resulting in hole position deviations or surface damage due to workpiece loosening. It cannot ensure its structural strength and operational safety. The device also lacks a waste chip collection structure. If waste chips remain in the processing area during the punching process, it may affect the punching position accuracy and hole diameter. Waste chips may also scratch the workpiece surface, causing scratches and other damage, affecting the appearance quality and surface roughness of the aluminum alloy steering knuckle.

Under the action of pressing the positioning rods 7 and the elastic action of the springs 9 on the force plate 8 and the side plate 6, the positioning rods 7 on both sides fix the outer side of the aluminum alloy steering knuckle.

[0026] like Figures 1 to 5 As shown, the bottom of the pressure plate 5 is fixedly connected to an internal threaded sleeve 10. The inner surfaces of the two internal threaded sleeves 10 are threadedly connected to positive and negative threaded rods 11. The outer surfaces of the positive and negative threaded rods 11 are rotatably connected to the inside of the main housing 1 and extend out one end. Rotating the threads will drive the internal threaded sleeves 10.

[0027] like Figures 1 to 5 As shown, a mounting sleeve 12 is fixedly connected to one side of the main housing 1. A first motor 13 is fixedly embedded on the inner surface of the mounting sleeve 12. The output end of the first motor 13 is fixedly connected to one end of the positive and negative lead screw 11. When the first motor 13 is powered on, it will drive the positive and negative lead screw 11 to rotate inside the main housing 1.

[0028] like Figures 1 to 5As shown, two fixing plates 14 are fixedly connected to the top of the main housing 1, and a punching machine 15 is fixedly connected to the top of the two fixing plates 14. The punching machine 15 can punch holes in the aluminum alloy steering knuckle.

[0030] like Figures 1 to 5 As shown, two connecting plates 18 are fixedly connected to the inner surface of the intake pipe 17. A second motor 19 is fixedly connected to one end of the two connecting plates 18 away from the intake pipe 17. The second motor 19 is fixed to the inner surface of the intake pipe 17 through the connecting plates 18.
