Embodiment 1

[0038] Such as figure 2 As shown, the requirements for automatic turning chip breaking are to ensure the physical, mechanical properties and surface quality of the workpiece after it is processed into parts; to ensure the safety of the operator without damaging the machine tool; to ensure the service life of the tool 5; to ensure reliable chip breaking and not to be entangled with each other . The commonly used chip breaking methods are tool chip breaker chip breaking, mechanical device chip breaking, energy (light energy, thermal energy, electric energy, vibration) chip breaking.

[0039] The chip breaking of the tool chip breaker needs to change the tool structure, which will bring other problems, such as reducing the surface quality of the workpiece; for materials with better plasticity, no matter how the structure of the tool edge is changed, the chip breaking cannot be effective. Other chip breaking methods require complex structures and equipment, poor stability, great...

Abstract

The invention discloses an automatic machining method of a thin-wall hemispherical shell, and belongs to the technical field of automatic mechanical machining. The method specially comprises the stepsthat (1) a vacuum suction tool is taken and is assembled and connected to a vacuum air pump, and a vacuum cavity of the vacuum suction tool is made to form negative pressure; (2) a workpiece to be machined is adsorbed on the vacuum suction tool; (3) radial feed and axial feed is intermittently carried out on the workpiece to be machined in the machining process; and (4) machining of the workpieceto be machined is completed. By ingeniously designing the feed mode, the chip breaking problem in the plastic material machining process is effectively improved, the chip winding condition of a cutter is improved, manual intervention during machining is avoided, effective guarantee is provided for automatic machining, the method is reasonable in design and easy to implement, machining precision and quality of the thin-wall hemispherical shell can be greatly improved by using the method, and the method is suitable for an automatic production line.

Description

technical field [0001] The invention belongs to the technical field of automatic mechanical processing, and in particular relates to an automatic processing method for a thin-walled hemispherical shell. Background technique [0002] Thin-walled hemispherical shells are widely used in various industries. In order to ensure their dimensional accuracy, turning is a widely used process. One of the difficulties in turning thin-walled hemispherical shell parts is how to clamp the workpiece on the lathe spindle, which can not only ensure the reliable positioning of the workpiece, but also avoid the influence of the clamping force on the dimensional accuracy of the workpiece. The general clamping methods include chuck clamping, open set clamping, expanding core clamping, and faceplate clamping. These clamping methods exert a large force on the workpiece, and require the workpiece to have a corresponding locking and fixing position. Thin-walled hemispherical shells are easy to defo...
