Finish-milling clamp for automobile steering knuckles and application method

Abstract

The invention relates to the technical field of fine processing for steering knuckles and discloses a finish-milling clamp for automobile steering knuckles and an application method. The finish-milling clamp for the automobile steering knuckles is characterized by comprising a base, a fastening device and a compression device, the fastening device is arranged at one side of the base, and the compression device is arranged at the other side of the base; the fastening device comprises positioning piles arranged at the two sides of the base, the positioning piles are provided with positioning holes, and core shafts are arranged in the positioning holes and used for being connected with the positioning piles and the steering knuckles; the compression device comprises a compression plate, a sleeve arranged below the compression plate and a V-shaped top body close to the fastening device. By using a rotatable positioning device, the finish-milling clamp is self-adaptive to the angle of a workpiece, the flexibility of the clamp is improved, multiple products share one clamp, the replacement and assembly frequency is reduced, by further using a cushion block with a step, the fulcrum of theworkpiece is forward transferred, with assistance of the sleeve, the force arm is lengthened, the pressing force is increased, vibration of the workpiece is reduced, and the product precision is improved.

Description

technical field [0001] The invention relates to the technical field of steering knuckle fine machining, in particular to an automobile steering knuckle fine milling jig and a use method thereof. Background technique [0002] Steering Knuckle, also known as "horn", is one of the important parts in the steering axle of a car, which can make the car run stably and transmit the driving direction sensitively. The function of the steering knuckle is to transmit and bear the front load of the car, support and drive the front wheel to rotate around the kingpin to turn the car. When the car is running, it bears variable impact loads, so it is required to have high strength. The steering knuckle is the hinge for the steering of the wheel, generally in the shape of a fork. The upper and lower forks have two coaxial holes for installing kingpins, and the steering knuckle journal is used for installing wheels. The two lugs of the pin hole on the steering knuckle are connected with the...

Problems solved by technology

[0003] The existing fixtures are not very inclusive, and a set of fixtures can only adapt to products with one angle. Usually, a factory will produce more than three different steering knuckles with different angles between the kingpin hole and each batch of production needs to be replaced. , is very troublesome, even if multiple production lines are used to produce at the same time, there will often be fluctuations in the order quantity, and it is necessary to frequently deploy machines, and it is even more troublesome to replace fixtures

Frequent and repeated fixture replacement is also easy to make workers feel bored
