Abstract
Bore mould is a machine components process equipment, there is quite extensive application when processed in the body part processing of case especially hole department. It designs to be existing to bore foundation that the mould is designed design and succeed in some originally. In the design,it has combined the relevant information of valuable experience and advanced technology in the production practices in the design, and set out from producing the angles, such as real and economy,etc. study and prove. Its design principle is guaranteeing that the case body makes a reservation and clamps safe, reliably in the course of processing, on the foundation easy to operate, through an analysis of craft scheme of bore hole, bore the design and exertion that the model and hole processed the cutter, used in the desk-top lathe locomotive case the hole department to process mainly. Originally design and can accomplish the structure steadily, the work is reliable, convenient to use and maintain.When the products are upgraded, part in common use, the standard component can also be utilized again, do not need to make again,so it has wide market prospects.
