Fix blade disc frame on the boring bar, handle transmission lead screw, the lead screw drives the cutter holder up -and -down motion to reach in a flexible way, controllable, high -efficient, product part size that processing was come out is stable, the quality is reliable, the utility model discloses blade disc frame compact structure, safe in utilization, with low costs, simple and convenient feasible.

Description

A kind of cutterhead frame

Technical field

The utility model belongs to hole, the end face part manufacture field of horizontal clear water centrifugal pump, is specifically related to a kind of cutterhead frame.

Background technology

The prosperity in water pump market and development, make the Requirement Increases of horizontal clear water centrifugal pump.A handle of a knife fixed by the horizontal pump housing of current processing many employings boring bar, handle of a knife often rotates a circle, hand hammer is needed to hit handle of a knife afterbody, to complete a feed, cause that work is delayed, labour intensity is large like this, feed is how many difficultly grasps, the surface accuracy required design parameter, dimensional accuracy, positional precision are difficult to ensure, and the process-cycle is long.

Summary of the invention

The purpose of this utility model is for above-mentioned deficiency, provides a kind of and make that machining accuracy is high, efficiency is high, reduces the cutterhead frame of labour intensity.

The utility model solves the technical scheme that its technical problem adopts: provide a kind of cutterhead frame, comprise upper tool pan seat and lower cutter chuck holder adapted, described upper tool pan seat comprises upper fixed seat and is arranged on the upper shell on upper fixed seat, and described lower cutter chuck holder adapted comprises lower fixed seat and is arranged on the lower shell on lower fixed seat; The cavity that screw mandrel is combined to form through lower shell endoporus, upper fixed seat and lower fixed seat successively, upper shell inner chamber are until leading screw top is deep in the cutter holder in upper shell, and the bottom of described screw mandrel is fixed on the handle of lower shell end; Nut passes the through hole of upper shell periphery, the keyway of cutter holder successively until be locked on described screw mandrel.

Further, the diameter of bore of described lower shell is identical with the external diameter of described screw mandrel.

Further, the end winding support that described cutter holder is deep in described upper shell has pressing plate, and described pressing plate has screwed hole, and the top of described screw mandrel is through pressing plate screwed hole until be deep in cutter holder, and described screwed hole matches with the external screw thread of described screw mandrel.

The utility model compared with prior art, have following beneficial effect: be fixed on boring bar by cutterhead frame of the present utility model, handle drive lead screw, screw mandrel drives cutter holder to move up and down, thus reach flexible, controlled, efficient, the product parts dimensionally stable, the reliable in quality that process; The utility model cutterhead shelf structure is compact, use safety, cost are low, simple and feasible.
