[0002] Steering knuckles are crucial safety components in automobiles, and industry professionals worldwide highly value their safety characteristics. A thorough understanding of these safety characteristics is paramount in steering knuckle manufacturing and should be integrated into the entire production process. The function of the steering knuckle is to transmit and bear the load from the front of the vehicle, supporting and driving the front wheels to rotate around the kingpin, thus steering the vehicle. During vehicle operation, it withstands varying impact loads; therefore, it requires high strength, which in turn imposes stringent standards on the manufacturing process to ensure that the produced steering knuckles can fully withstand high-intensity loads.

[0003] Existing steering knuckle machining fixtures cannot manually adjust the side clamping angle and position according to actual conditions, cannot manually adjust the local height of the steering knuckle, and cannot perform deeper local finishing on the steering knuckle.

[0004] Therefore, it is necessary to design a machining and fixing fixture for forklift steering knuckles to improve the above problems. Utility Model Content

[0033] The working process of this utility model is as follows: First, the circular hole on the steering knuckle is used to pass through the clamping plate 401 and is sleeved on the outside of the connecting rod 402 of the clamping member 4. The rotating handle 3033 drives the second bevel gear 3034 to rotate, causing the second bevel gear 3034 and the first bevel gear 3032 to rotate, driving the adjusting screw 3031 to rotate. The sliding plate 403 is moved and adjusted by the threaded adjustment hole 4031 and the adjusting screw 3031, so that the clamping member 4 is moved towards the adjusting cylinder 3. The positioning strip 4014 is pulled out from the limiting slide groove 4011. The second return spring 4013 pushes the elastic block 4012 to be inserted into the corresponding positioning hole 4015, preventing the steering knuckle from falling off the outside of the clamping member 4 during the movement and adjustment of the clamping member 4. The positioning strip 4014, together with the side of the adjusting cylinder 3, clamps and secures the steering knuckle. The anti-slip pad 302 on the side of the adjusting cylinder 3 cooperates with the rubber pad 4016 on the side of the elastic block 4012 to enhance the clamping stability of the steering knuckle. The second pull rod 2014 pulls the block assembly 2013 to retract and descend in the movable groove 2011. The first pull rod 301 pulls the adjusting cylinder 3 to rotate through the guide slide groove 305 and the T-shaped slider 202, which drives the steering knuckles installed on both sides of the adjusting cylinder 3 to adjust the angle according to the processing requirements. The first return spring 2012 pushes the block assembly 2013 to embed into the corresponding limiting hole 304 through its own elasticity, which limits and fixes the adjusting cylinder 3 after rotation adjustment. The electric telescopic rod 102 pushes the lifting frame 2 to adjust the height through the directional pulley 203 and the directional slide groove 101.

[0034] The entire operation process is simple and convenient. Compared with existing machining fixtures, this utility model is designed to facilitate the rotational adjustment of the machining angle of the steering knuckle according to requirements, thereby enhancing its overall practicality.
