Abstract
The utility model discloses a precision and deep hole drilling auxiliary device of a lathe, and belongs to the technical field of auxiliary lathe tools. Based on the conventional lathe structure, the device is characterized in that a support frame is arranged on a lathe body, the support frame is fixed by a cross arm rack and a bolt, and a fixed drill bushing is arranged on the support frame. The device can be used for drilling precision holes and deep holes without changing the conventional lathe structure.
Description
Technical field
The utility model relates to a kind of lathe and bores the precision deep bore servicing unit, belongs to lathe worker accessory technical field.
Background technology
Engine lathe is a kind of general metal-cutting machine tool; Simultaneously, on lathe, also carry out some boring operations, when traditional lathe is made the boring operations; Mainly be to utilize the drill bit that is installed on the tail stock to accomplish; Since lathe structurally mainly be for Vehicle Processing technology specially designed, so traditional lathe can only be bored the hole that some precision are lower, hole depth is more shallow.
Summary of the invention
The purpose of the utility model is: because structure aspects, be unfavorable for boring precision and than the scarce limit of deep hole, the utility model provides a kind of lathe to bore the precision deep bore servicing unit to existing engine lathe.
The utility model realizes that the above-mentioned technical scheme that is adopted is: a kind of lathe bores the servicing unit of precision deep bore.The technical scheme that it adopts is: on the architecture basics of existing lathe; Face is provided with a bearing support on one's body lathe; The bottom of lathe body guide rail is provided with a cross-arm frame under bearing support; Link with bolt between bearing support and the cross-arm frame, on bearing support, install and fix drill bushing, the main core line of the center line of described drill bushing and lathe is in concentric position.
Beneficial effect: the utility model is because after adopting above-mentioned method, in boring, as long as pass through the position of adjustment bearing support; Make drill bushing as far as possible near-earth near workpiece; With drill bit at first through contact with workpiece again behind the drill bushing, owing to the aiding support effect of drill bushing to drill bit, limited drill bit at work vibration and with the scarce limit of workpiece centre decentraction; So, can reach and bore PRECISION HOLE and than the purpose of deep hole.
Description of drawings
Accompanying drawing 1 is the structure principle chart of the utility model;
Accompanying drawing 2 is A-A sectional views of accompanying drawing 1;
Shown in the figure: 1, bed piece; 2, bearing support; 3, drill bushing; 4, cross-arm frame; 5, bolt.
The specific embodiment
Keep the traditional lathe structure constant; On the basis of existing lathe structure; A bearing support 2 is set on the guide rail on bed piece 1, a cross-arm frame 4 is set below bed piece 1 guide rail under bearing support 2, connect bearing support 2 and cross-arm frame 4 fixing with bolt 5.In use, release bolt 5 through regulating the position of bearing support 2 on bed piece 1, is close drill bushing 3 as much as possible with workpiece, simultaneously, drill bit is contacted again with workpiece through drill bushing 3.
