The invention provides a clamp for a corner joint. The clamp comprises two clamping units which are matched with each other, wherein clamping grooves for storing the corner joint are formed in relative side surfaces of the two clamping units; the upper ends of the clamping grooves are opened; mounting teeth are arranged at the bottom of the clamping units; and counter bores are formed in the clamping units along the vertical direction. The invention further provides a machining method. The clamp for the corner joint and the machining method, provided by the invention, have the following advantages that only if the clamping grooves of the clamp are designed into an angle needed by a product, turning machining of the corner joints with different angles can be easily finished; sizes and geometrical tolerances of workpieces are ensured and the limitation of machining products by adopting equipment including a five-axis machining center and the like is solved; the clamp for the corner joint has the characteristics of simplicity and convenience, rapidness, strong commonality, high labor productivity and the like and is simple in structure and reasonable in design; and the installation time is saved, existing equipment is reasonably utilized and the production cost is reduced.
Description
technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a fixture and a processing method for an elbow joint. Background technique [0002] The traditional way of general angle pipe joint parts is welding or casting. However, the biggest problem with welding is that the thermal expansion and force of the weld can hardly be calculated accurately and cannot be accurately simulated, which is contrary to the high precision of aerospace parts; while casting has high cost and low precision for small batch products, and is not suitable for single Parts production and high-precision workpieces. [0003] This patent is mainly to solve the problem that the angle pipe joint workpiece has a certain angle, and the machining center is not in the center of the spindle. A special tooling chuck is designed to adjust the angle and position of the workpiece relative to the lathe, so as to achieve the turning process of any angle pipe jo...
