Abstract
The utility model discloses a burnishing -in instrument, including the cutter arbor, the one end of cutter arbor is equipped with the groove that matches with the bush on the surface, the bush is equipped with the blind hole with the steel ball close -fitting, the steel ball exposes in partial 12 of the steel ball diameter that is less than in bush drill way. The material of bush is polytetrafluoroethylene material or engineering plastics. The utility model has the advantages of need not increase roller worker equipment can reach luminosity requirement therefore with low costs showing.
Description
Technical field:
This utility model relates to a kind of chipless process technology, particularly a kind of burnishing-in instrument.
Background technology:
Hole machined in thin arm-piece, when surface smoothness requirements height, can not reach requirement, the generally face, hole to numerical control machine bore through face, the hole luminosity that numerical control machine bore is former, uses burnishing-in to realize, and this will increase burnishing-in equipment and instrument, cause cost to increase.
Summary of the invention:
The purpose of this utility model is to provide the burnishing-in instrument of a kind of low cost.
The technical solution of the utility model is, a kind of burnishing-in instrument, including knife bar, it is characterised in that: the end surface of described knife bar is provided with the groove matched with lining, described lining is provided with and the blind hole of steel ball close-fitting, and described steel ball exposes to lining bore portions less than the 1/2 of steel ball size.The material of described lining is polytetrafluoroethylmaterial material or engineering plastics.
This utility model have compared with the prior art need not to increase roller construction equipment i.e. can reach photometric requirement thus the remarkable advantage of low cost.
Accompanying drawing illustrates:
Fig. 1 is this utility model burnishing-in tool construction schematic diagram, and Fig. 2 is the schematic diagram carrying out burnishing-in with burnishing-in instrument on numerical control machine.
Detailed description of the invention:
This utility model uses the instrument shown in Fig. 1, one groove is set in the termination of power bar and matches with supporting set 2, should support in set and be provided with a blind hole, steel ball 3 is pressed in this blind hole, the exposed parts ＜ steel ball size 1/2 of this steel ball, the magnitude of interference between steel ball and bush hole meets steel ball and will not depart from from hole, and steel ball can rotate during dynamic to workpiece hole roller.Steel ball should have high abrasion resistance, and lining uses polytetrafluoroethylmaterial material or engineering plastics, and knife bar is conventional force bar.The using method of this utility model burnishing-in instrument, to treat that burnishing-in thin-wall workpiece 4 is installed on the chuck of Digit Control Machine Tool, make burnishing-in instrument of the present utility model that the hole wall of thin-wall workpiece is carried out burnishing-in, the top of power stricture of vagina on hole wall is carried out roll-in by steel ball, only improve the fineness of hole wall, this burnishing-in instrument is used to save burnishing-in equipment, thus low cost.
Claims (2)
1. a burnishing-in instrument, including knife bar, it is characterised in that: the end surface of described knife bar is provided with the groove matched with lining, and described lining is provided with and the blind hole of steel ball close-fitting, and described steel ball exposes to lining bore portions less than the 1/2 of steel ball size.
2. a kind of burnishing-in instrument as claimed in claim 1, it is characterised in that: the material of described lining is polytetrafluoroethylmaterial material or engineering plastics.
