Abstract
The invention discloses a roller burnishing tool, which comprises a tool bar. A groove matched with a bush is formed in a surface of one end of the tool bar; the bush is provided with a blind hole in close fit with a steel ball; and a portion, exposed from an orifice of the bush, of the steel ball is less than 1/2 of a diameter of the steel ball. The bush is made of a polytetrafluoroethylene material or engineering plastics. The roller burnishing tool has the remarkable advantage of low cost because of satisfaction of a finish requirement without additional rolling equipment.
Description
Technical field:
The present invention 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, the hole face luminosity former through numerical control machine bore can not reach requirement, generally the face, hole to numerical control machine bore, adopts burnishing-in to realize, and this will increase burnishing-in equipment and instrument, cause that cost increases.
Summary of the invention:
It is an object of the invention to provide the burnishing-in instrument that a kind of cost is low.
The technical scheme is that, 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.
The present invention has compared with the prior art need not be increased roller construction equipment and can reach photometric requirement thus the low remarkable advantage of cost.
Accompanying drawing illustrates:
Fig. 1 is burnishing-in tool construction schematic diagram of the present invention, and Fig. 2 is the schematic diagram carrying out burnishing-in with burnishing-in instrument on numerical control machine.
Detailed description of the invention:
The present invention adopts 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 can rotate workpiece hole roller moves steel ball in process.Steel ball should have high abrasion resistance, and lining adopts polytetrafluoroethylmaterial material or engineering plastics, and knife bar is conventional force bar.The using method of burnishing-in instrument of the present invention, to treat that burnishing-in thin-wall workpiece 4 is installed on the chuck of Digit Control Machine Tool, the hole wall of thin-wall workpiece is carried out burnishing-in by the burnishing-in instrument making the present invention, 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, use this burnishing-in instrument to save burnishing-in equipment, thus cost is low.
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.
