Accuracy analysis of workpiece precision processed by lathe expansion fixture
A dial is placed at the free end of the worm to control the amount of rotation of the turntable. Clamping mechanism design. The mechanism is used to clamp the workpiece to be processed. The clamping port adopts a flat jaw type, which consists of a fixed clamping block and a moving clamping block. The moving clamping block is controlled by a screw. Rigidity and strength design Since the fixture is mounted on a lathe, the workpiece to be machined usually has a large size and weight, which will bring high strength requirements to the design of the fixture. The following reinforcement methods are used to strengthen the ribs in various forms, depending on the needs, such as triangular slabs, etc. to increase the size of the parts. Under the premise of not affecting the design requirements, the design size of the components is appropriately increased, and the deformation amount of the components under load is effectively reduced. Accuracy analysis The accuracy of the workpiece processed by the lathe expansion fixture is generally higher than that of the original lathe. There are two reasons for this. The positioning principle and the principle of tool setting used by it are adjustment methods. As we all know, the adjustment method can ensure the dimensional stability more than the trial cutting method. In addition, the tool holder and the positioning member are required to be processed by the matching lathe, and the positioning error value is extremely small. In theory, there is only the error in the secondary clamping, and the reference does not coincide. The error is two, using the lathe expansion fixture to achieve a multi-purpose machine, one-time clamping can complete multiple processes, which can greatly reduce the installation error. (Finish)
