ABSTRACT
With scientific and technological advancements, and the continued expansion of the scale of industrial production and increased automation, jig is used more and more wildly in the modern production, and plays a more important role than before. At the same time high-precision and high-efficiency machine tool will be the development trend in the field. In the machinery manufacturing industry it in the processes of a wide variety of applications for processing, is named jig£¬which is fixed object to a correct position to receive a construction techniques and equipment. Whether in the mechanical processing, assembly, testing or in welding and heat treatment, such as cold, heat processes, and transportation, jig has to be used largely. But in the mechanical processing, the most widespread application is the use of metal cutting machine tools, namely fixtures, which we call the machine tool jig. In machine tooling, machine tool jig is used to install working and tools accurately and quickly, thus ensuring inter-working with cutlery to a correct position. Machine tool jig generally can be divided into two categories. The first category is for the installing working, commonly known as fixtures; the other is to install tools, while as term. The chuck on the car belongs to the former and is a common machine tool jig.
In the mechanical processing, the demand of high-speed and high-precision increases, so chuck which joins the machine tools and workpiece is more and more focused. In order to satisfy the request that the customer pursues the diversification, high specification machine to process, they have developed kinds of chunk continuously. Chuck is divided into manual and power or motive chuck, power chuck on the CNC lathe and automatic lathe is an important component and part, among which hydraulic power chuck and pneumatic power chuck are most popular. At present a general lathe spindle back-end is serviced with external rotation or piston-engine tank rotation motive oil urn, as a result of high-speed rotation, therefore on the target material, intensity, high-speed and high-speed precision balanced with oil, sealed, keeping pressure and so on are in higher demanding, in addition, as the bearings of the main axis are carrying larger push pull, the stability and high-speed rotation axis precision, life are affected partly.
Non-rotation high-speed links impetus chuck devices, as plate drive tanks and plate-piston don¡¯t rotate with the main axis, which effectively reduced the revolve spare parts quantities and rotary quantities with the principal axis, and because plate drive tank is not spinning, either facilitate simple, easy sealed and keeping pressure, so the plate drive tank is installed directly in the main box, it will help to raise the main motion balance, and simplify the influence factors in the principal axis design.
