Problems solved by technology
The steering knuckle includes a rod, a flange, a connecting part and a fork, and the connecting part is provided with a connecting hole. When processing the flange and the fork, traditionally, a horizontal machining center is used to press the front of the disc with a clamp. (the side close to the fork) to fix the workpiece. This method is not suitable for steering knuckles with a small positioning surface. At the same time, because the clamp covers and blocks the front of the disc, it is impossible to connect the flange and the fork. Complete machining, and the complex structure of the front of the disc, which makes it difficult to clamp the steering knuckle

Embodiment
[0033] Embodiment, a kind of clamping method of steering knuckle, comprising the following steps:
[0034] (1) Forging: Die forging is performed on the steering knuckle, and a positioning disc 921 perpendicular to the axis of the steering knuckle rod 91 is forged between the steering knuckle rod portion 91 and the steering knuckle disc portion during die forging;
[0035] (2) Turning: rough threading the end of the steering knuckle rod portion 91 away from the disc portion;
[0036] (3) Clamping: Clamp the steering knuckle by tightening the fixing clamp;
[0037] As shown in the figure, the tightening fixture includes a mounting plate 1 and a positioning plate 2 fixedly connected to the mounting plate 1. The positioning plate 2 is provided with a positioning hole 21 for the steering knuckle rod portion 91 to protrude. The mounting plate 1 and the positioning plate Two reinforcing ribs 11 respectively located on both sides of the positioning hole 21 are welded between 2, the p...

The invention relates to the field of machinery, and discloses a method for clamping a steering knuckle, which comprises the following steps: forging, turning and clamping; a tightening and fixing fixture includes a mounting plate and a positioning plate; the positioning plate is provided with a positioning hole; One end of the steering knuckle rod extending out of the pressing sleeve is sleeved with a pressing sleeve, and one end of the steering knuckle rod protruding from the pressing sleeve is threadedly connected with a pressing nut, and a positioning pin is inserted on the positioning plate. The invention has the following advantages and effects: the steering knuckle is axially positioned by using the rough-turned thread at the end of the steering knuckle rod end with the positioning disc, avoiding the clamping and blocking of the front of the disc part, and realizing the clamping of the steering knuckle Secondly, the steering knuckle is circumferentially positioned by the positioning pin, and the connecting part is supported at the same time, which improves the stability of the steering knuckle setting; a guide column is arranged on the positioning plate to guide the connecting part and the guide rod is guided by the contact switch. The lifting control is carried out to realize the rapid positioning of the positioning pin and the connecting hole.
Description
technical field [0001] The invention relates to the technical field of machinery, in particular to a method for clamping a steering knuckle. Background technique [0002] The steering knuckle is one of the main parts on the steering axle of a car, which can make the car run stably and transmit the driving direction sensitively. The steering knuckle includes a rod part, a flange plate, a connecting part and a fork part. The connecting part is provided with a connecting hole. When machining the flange plate and the fork part, a horizontal machining center is traditionally used to press the front of the disk part with a clamp. (the side close to the fork) to fix the workpiece. This method is not suitable for the steering knuckle with a small positioning surface. At the same time, due to the partial covering and blocking of the front face of the facing plate by the clamp, it is impossible to abut the flange and fork. Complete machining is performed, and the frontal structure of...
