Description

Machining clamp capable of adjusting levelness and rotation degree of workpiece

[ technical field ] A

The utility model relates to the technical field of mechanical design, in particular to a machining clamp capable of adjusting levelness and rotation of a workpiece.

[ background of the utility model ]

In the mechanical production engineering, some non-standard products are connected in order to improve the economic benefit. In the processing process of the non-standard products, special inclined holes are required to be processed, and due to the fact that the non-standard quantity is not large and the shapes are different, special drilling tools can not be equipped for the non-standards, and therefore the special inclined holes are difficult to process. The main reason for the difficulty is that the structure of the common drilling machine is simple, and only vertical downward drilling or tapping can be performed, so that the situation of uneven stress is generated when a drill bit contacts a curved surface or an inclined surface of a workpiece, and finally the deviation of the hole site drill and even the damage of a cutter are caused. The traditional processing clamp for drilling the inclined hole has the following defects: for example, the special fixture for fixing the inclined hole has the defects of small application range and poor precision adjustment capability although the operation is simple; for example, the application range of the drilling jig with the adjustable inclined surface is improved to a certain extent, but the operation is troublesome when a plurality of inclined holes are machined, and the accurate positioning is difficult.

Kinematic interference is a concept of mechanical design. In the field of mechanical design, interference refers to a part coming into contact with another part (the distance is less than a set clearance value, not necessarily zero). Motion interference refers to interference of parts during motion, for example, adjacent rotating members contacting during motion. Flanges (Flange), also called Flange discs or flanges, are parts of the interconnection between shafts.

The utility model makes technical improvement on the machining clamp capable of adjusting the angle of the workpiece.
