Technical field

The present invention relates to lathe equipments technical fields, relate in particular to a kind of processing unit (plant) for lathe.

Background technique

Thin-wall circular tube part due to its relative weight is relatively light, save material, be compact-sized the advantages that.In many engineering goods In be commonly used.But there is also the features that wall is thin and stiffness and strength are insufficient for thin-wall circular tube part.Therefore, in processing thin-wall circular tube The problems such as it is easy to appear stress deformation, temperature distortion and vibration deformations in workpiece fabrication.Especially when carrying out turnery processing, If directly using clamping with three-jaw chuck workpiece, it easily generates stress deformation under the action of scroll chuck clamping force, leads to it Dimensional accuracy and deformation tolerance are difficult to ensure and control, and existing workpiece fixture is typically only capable to for processing thin-wall circular tube zero Part, purposes are single.

Summary of the invention

The purpose of the present invention is providing for the above-mentioned problems in the prior art, a kind of manufacturing cost is low, uses Convenient, the multiduty processing unit (plant) for lathe.

In order to achieve the above-mentioned object of the invention, the invention adopts the following technical scheme: a kind of processing unit (plant) for lathe, Including lathe and the cutter being installed on scroll chuck, which is characterized in that the cutter includes cutter shaft and blade, described Cutter shaft is clamped by scroll chuck, and blade is installed on cutter shaft, and work piece holder is also equipped in the sliding box of the lathe, described Work piece holder include bottom plate and the external clip and internal clip that are set on bottom plate, the external clip is equipped with peace outstanding Seat is filled, fixed link is installed in the mounting base, the fixed link is by screw thread rotation by workpiece clamp in external clip and interior It is clamped between clamp.

The working principle of the invention: in use, workpiece is mounted on external clip and internal clip, then bottom plate is mounted on vehicle It is using fixed link that workpiece secured adjusted is good on bed in sliding box, by set on the end face and sliding box of bottom plate and mounting base Installs fixture fix, fixed link pass through installs fixture reach outside, if processing circular shaft part, it is straight without using internal clip It connects and is fixed using fixed link, fixed cutting tool on the scroll chuck of lathe, scroll chuck band cutter rotates, and mobile sliding box carries out Charging processing；When processing, first go out bottom plate, external clip and internal clip, fixed link or directly casting using machine tooling, then will be outer Clamp welds together with bottom plate, and cutter is formed using machine tooling.Setting using the above structure, it is easy to operate, it can keep away Exempt from workpiece to deform under the action of scroll chuck clamping force, while ensure that dimensional accuracy and deformation tolerance, workpiece clamp is signed an undertaking Structure is simple, can be made according to workpiece size, and production cost is low, can be directly transformed on original lathe, without more It changes trains and bed and restructuring processing is carried out to lathe part, cost is greatly saved, it is applied widely.

In a kind of above-mentioned processing unit (plant) for lathe, several adjusting blocks are additionally provided on the cutter, it is described Adjusting block is additionally provided with locking for adjusting blade along the distance of cutter shaft length direction and limiting to blade on the cutter shaft Nut, the locking nut is for locking blade.

In a kind of above-mentioned processing unit (plant) for lathe, it is additionally provided with locking hole on the external clip, passes through connection Part further fixes workpiece.

In a kind of above-mentioned processing unit (plant) for lathe, the fixed link includes the body of rod and handle, the handle Hand is equipped with screw thread by welding the body of rod tail portion for being connected T-shaped, described with the body of rod.

In a kind of above-mentioned processing unit (plant) for lathe, the mounting base is located at external clip top center position It sets.

In a kind of above-mentioned processing unit (plant) for lathe, the mounting base and external clip are welded.

In a kind of above-mentioned processing unit (plant) for lathe, the mounting base and external clip are integrally cast.

Compared with prior art, using a kind of processing unit (plant) for lathe of above-mentioned technical proposal, have has as follows Beneficial effect: the present invention compares, easy to operate, can be avoided workpiece and deforms under the action of scroll chuck clamping force, protects simultaneously Dimensional accuracy and deformation tolerance are demonstrate,proved, work piece holder structure is simple, can be made according to workpiece size, production cost is low, energy It is enough to be directly transformed on original lathe, no replacement is required lathe and restructuring processing is carried out to lathe part, is greatly saved into This, it is applied widely.
