Description

Steering knuckle machine plus fixture

technical field

The utility model relates to a steering knuckle machining clamp, which belongs to the field of mechanical equipment.

Background technique

The steering knuckle is one of the main parts on the steering axle of the car. The function of the steering knuckle is to bear the load on the front of the car, support and drive the front wheel to turn around the kingpin.

The structure of the steering knuckle as shown in Figure 1 includes the main body of the steering knuckle, three arms distributed on the main body and the ear-shaped structure a, and the shortest arm is the lower swing arm b.

After casting the blank, the steering knuckle needs to be milled and drilled. At present, the five-axis machining center is used to mill and drill the steering knuckle. Designing a suitable fixture for this machining center is also a problem that we need to solve. .

Utility model content

In view of the existing problems, the purpose of the utility model is to provide a steering knuckle frame clamp, which can play a good role in fixing the steering knuckle and is convenient for machining.

In order to achieve the above object, the technical solution of the utility model is: a steering knuckle machining clamp, including a circular clamp base plate, characterized in that: the upper surface of the clamp base plate corresponds to the three arms and ear structures of the steering knuckle respectively A positioning ball head is provided, and the positioning ball head is installed on a positioning seat. An oil cylinder is arranged next to each of the positioning seats. The position is set with a "U"-shaped hinged seat of the pressing arm composed of two vertical blocks and a lower connecting block. On the top, the piston rod of the oil cylinder passes through the pressure plate and is connected with the tail end of the pressure arm.

With the above scheme, when in use, the fixture is installed on the machining center to support the corresponding position of the steering knuckle on the positioning ball head, and then the piston rod of the oil cylinder moves upwards, and the pressing arm presses the steering knuckle tightly, and then processing can be performed, and the fixation is reliable. The utility model utilizes the three arms of the steering knuckle and the ear-shaped structure for positioning, and more conveniently performs surface milling and drilling processing.

In the above solution: the upper surface of the clamp bottom plate is provided with a positioning ball head corresponding to the three arms of the steering knuckle and the ear-shaped structure close to the lower swing arm.

The beneficial effects of the utility model are: the utility model has simple structure, convenient and reliable positioning, and the utility model utilizes the three arms of the steering knuckle and the ear-shaped structure for positioning, and it is more convenient for surface milling and drilling.
