Tool combination structure of lathe turning inner expansion type tool

Technical Field

The utility model relates to an interior expanding frock technical field specifically is a frock integrated configuration of expanding frock in lathe work.

Background

At present, when lathe turning is carried out, a product is clamped by hydraulic pressure and manual self-centering three claws, and in order to prevent the phenomenon that the product cannot be clamped and slips in the finish machining process, the pressure of a hydraulic system is increased (or an operator screws the product through a stress application rod), the wall thickness of the product is thin, and the product is often deformed.

For a workpiece with a small and long diameter, when an excircle is clamped, the phenomenon of cutter vibration is easy to occur, so that the machined product is scrapped due to the fact that the machined product does not meet the requirement of the appearance surface.

The currently used tool clamp is generally an outer clamping three-jaw and an inner expansion three-jaw which are manufactured according to the product requirements. The internal expansion three-jaw is suitable for processing large-size (4-inch and above) products, and for products with the specification below 4 inches, certain use limitation and tool manufacturing complexity exist. For a product with a longer product, when the special three-jaw is manufactured, in order to prevent the cutter from vibrating during machining, the clamping part can also be made very long, and when the special three-jaw is produced in a large scale, the external three-jaw clamp can be opened outwards and deformed to clamp a product difficultly by multiple times of clamping, so that the three-jaw clamping part needs to be turned once again after a certain amount of clamping.

There is a clamp that can solve the above problems, but such a clamp has disadvantages: because the structural design of the tool body and the tool pull rod support is unreasonable, the tool body and the tool pull rod support are not convenient to clamp, the workpiece assembling and disassembling speed is low, the clamping time of a product is greatly prolonged, and the machining efficiency is influenced, so that the tool combination structure of the inner expansion type tool for lathe turning is provided.
