Technical field
The utility model relates to a kind of screw thread processing unit (plant), especially relates to a kind of to being loaded on the structural improvement of the external screw thread processing unit (plant) on the lathe.
Background technology
In order to process screw thread on workpiece, people have designed diversified screw thread processing unit (plant), comprise female thread machining device and external screw thread processing unit (plant).For the external screw thread processing of the less demanding workpiece of accuracy of thread, have in the prior art and adopt the mode of manual processing to process.Though this mode can process external screw thread, operating efficiency is lower, and adding wastes time and energy man-hour, and its scope of application is very restricted.Particularly at the required precision height, when processing tasks was urgent, the device of this manual processing can't satisfy the demand of work at all.In addition, owing to undertaken by manual, the inevitable difference to some extent of the screw thread specification that at every turn processes is not suitable for suitability for industrialized production.
For this reason, but someone has designed a kind of tapping device (application number: CN03277854.6) of controlling depth, comprise taper shank body and screw tap, the front end that it is characterized in that the taper shank body is provided with collet body, sliding sleeve, adjust cover, collet body is contained in the endoporus of taper shank body and becomes matched in clearance, have on the taper shank body opening wall and drive the steel ball that collet body rotates, the outside of steel ball contacts with sliding sleeve on being enclosed within the taper shank body, sliding sleeve leading portion aperture is greater than the back segment aperture, before the sliding sleeve, after axial limiting spare and compression spring are arranged respectively, described adjustment cover is positioned at the collet body periphery, be threaded with sliding sleeve, screw tap passes the hole clamping of adjustment cover front end on collet body, and it is the transfer pin on inclined-plane that spring and external part are housed in the radial hole of collet body.Though this device can make the screw thread specification of each processing reach unanimity, overall structure is comparatively complicated, manipulates very inconveniently, and cost of manufacture is higher.
Summary of the invention
Main purpose of the present utility model provides a kind of can connecting on lathe, realizes screw thread processing automatically, and easy operating, high efficiency, the reliable external screw thread processing unit (plant) of the workpiece accuracy that processes; Solved the existing in prior technology inefficiency, the workpiece accuracy that processes is poor, the technical problem that operates and waste time and energy etc.
The utility model also has a purpose to provide a kind of simple in structure, and cost of manufacture is low, the external screw thread processing unit (plant) of good operating stability; It is comparatively complicated to have solved the existing in prior technology structure, the technical problem that cost of manufacture height, job stability are difficult to ensure etc.;
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the external screw thread processing unit (plant), be arranged on the lathe, comprise a taper shank that links to each other with lathe tailstock and the bolt die sleeve that can be enclosed within on the workpiece, bolt die sleeve and the coaxial setting of taper shank, it is characterized in that, described bolt die sleeve and taper shank are in axial sliding connection, and are provided with the bar shaped chute of axial setting on taper shank, are provided with a guide-localization post that can withstand in the bar shaped chute on the bolt die sleeve.
The utility model creatively is fixed on the taper shank and the bolt die sleeve of coaxial setting on the lathe, by the guide-localization post taper shank and bolt die sleeve is fixed up, and prevents to move axially between the two and left-right rotation, so that set the screw thread of workpiece to be processed.The cooperation by screw thread in the process of machining screw of bolt die sleeve is moved gradually vertically, excircle of workpiece week processes externally threaded purpose thereby be implemented in.After the completion of processing, lathe spindle drives the workpiece counter-rotating, throws off mutually down thereby bolt die sleeve and workpiece pass through the effect of screw thread, and the bolt die sleeve moves axially and resets.When needs changed the screw thread of setting, the guide-localization post was loosening, and taper shank and bolt die sleeve just can relatively move, thereby set again.
As preferably, described guide-localization post radially is located on the bolt die sleeve wall, links to each other by screw thread between the two, and the end of guide-localization post can withstand in the bar shaped chute, and bolt die sleeve and taper shank are coupled together.Owing to be to be threaded, the guide-localization post can lifting, so that adjust the position between bolt die sleeve and the taper shank.
As preferably, described bolt die jacket casing is located on the taper shank, the front end of bolt die sleeve have one pullover, on pullover, be provided with fixed leg.Pulloverly be used to carry out screw thread processing.
As preferably, described fixed leg radially is located on the pullover wall of bolt die sleeve, links to each other by screw thread between the two.
As preferably, described taper shank has a socket post, and the bolt die jacket casing connects thereon, and the external diameter of socket post is slightly less than the internal diameter of bolt die sleeve.
Therefore, the utlity model has following advantage: 1. adopt lathe to process, effectively overcome the defective that original manual mode exists, manipulate very conveniently, not only improved operating efficiency, the precision of product also is protected.2. simple in structure, cost of manufacture is low, good operating stability.3. owing to can set, the specification of workpieces that processes is unified, and can regulate voluntarily as required.
Description of drawings
Fig. 1 is a kind of broken section structure chart of the present utility model.
Among the figure, taper shank 1, bar shaped chute 1a, socket post 1b, bolt die sleeve 2, pullover 2a, guide-localization post 3, fixed leg 4.
The specific embodiment
