Abstract

The utility model relates to a conical inner bore honing tool which is characterized in that: the honing tool comprises a cutter bar, a spring, a spring shaft, a whetstone support and a whetstone which is fixedly arranged on the whetstone support; the cutter bar is equipped with stepped holes along the radial direction; the spring is sheathed on the spring shaft; the spring shaft and the spring which is arranged on the spring shaft are positioned in the stepped holes; the spring shaft is tightly fixed on the cutter bar through nuts and the other end of the spring shaft is in rivet joint with the whetstone support; the whetstone support is long groove shaped and inside the long groove is provided with the whetstone. By adopting the conical inner bore honing tool of the utility model during production process, the honing tool not only guarantees the processing precision of the conical surface but also meets the requirements of surface roughness, meanwhile, the conical inner bore honing tool has small volume and is easy to be disassembled and suitable for processing pieces with different tapers.

Description

A kind of circular cone inner bore honing instrument

Technical field

The utility model belongs to a kind of lathe or boring machine inner bore honing instrument, particularly relates to a kind of simple in structure, the circular cone inner bore honing instrument that can be close to surface to be machined.

Background technology

In the machined field, all very strict to the requirement of size, tolerance and the roughness of workpiece, but be limited to the restriction of working ability or machine tool accuracy sometimes, often be difficult to reach the every requirement on the drawing.As: the knife rest in certain company's flying shear project, its inner bore surface roughness require to reach Ra0.8, and the hole is the taper hole for 1: 30.The not so difficult processing of the tapering of endoporus both can become also boring to become by car, and the finish turning roughness can only reach Ra6.3～1.6 at present, though the accessible desired roughness value of right boring is Ra0.8, but is difficult in the practical operation reach; Utilize the inner bore honing lathe can reach the drawing requirement, though have many producers to make plover mill machine at present in the world, domestic only have 20 surplus the manufacturer production plover mill machine, and plover mill machine is as the tool of production of complexity, complicated operation, cost is higher; General workman adopts the grinding stone hand finish, and at first tapering requires to be difficult to guarantee that secondly the size of each several part also can't guarantee, and time-consuming, effort.

Summary of the invention

The utility model provides a kind of simple in structure, the circular cone inner bore honing instrument that can be close to surface to be machined for solving the technical problem that exists in the known technology.

The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:

A kind of circular cone inner bore honing instrument, it is characterized in that: this hone comprises knife bar, spring, spring shaft, oilstone holder and is packed in oilstone in the oilstone holder, described knife bar radially has shoulder hole, described spring housing is contained on the spring shaft, spring shaft and spring mounted thereto are contained in the shoulder hole, spring shaft is fastened on the knife bar by nut, and riveted joint has the oilstone holder on the other end of spring shaft, is fixed with oilstone in the oilstone holder.

The utility model can also adopt following technical measures:

Described spring shaft is made stepped, path place mounting spring, and path cooperates with knife bar shoulder hole aperture, and big footpath cooperates with knife bar shoulder hole macropore.

Described spring shaft bigger diameter end face is provided with boss, and the axis direction of boss has the hole, suit oilstone holder on boss, and the oilstone holder is riveted on the boss.

The oilstone that installs in the holder of described long trough oilstone is for semicircle, and the elongated slot inner surface is the circular arc that cooperates with semi-round stone.

Advantage and the good effect that the utlity model has are: owing to radially have shoulder hole at knife bar, mounting spring axle in shoulder hole, on spring shaft, be set with spring, spring shaft is fastened on the knife bar by nut, pass through the stroke of pocketed springs on the adjusting nut adjustable springs axle like this, be close to by the honing workpiece with the oilstone that installs in the riveted joint oilstone holder on the other end that guarantees spring shaft, and in the feed process, regulate thrust automatically by spring, not only guarantee the cone face process precision in process of production but also satisfied the requirement of surface roughness, simultaneously, the utility model volume is little, convenient disassembly, the part of the different taperings of suitable processing.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the right view of Fig. 1;

Fig. 3 is the utility model user mode schematic diagram.

Among the figure: 1, knife bar; 2, spring shaft; 3, spring; 4, oilstone holder; 5, oilstone; 6, nut; 7, workpiece.

The specific embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

See also Fig. 1 and Fig. 2, this hone comprises knife bar 1, spring 3, spring shaft 2, oilstone holder 4 and is packed in oilstone 5 in the oilstone holder 4; Wherein radially have shoulder hole at knife bar 1, spring 3 is sleeved on the spring shaft 2, spring shaft 2 and spring 3 mounted thereto are contained in the ladder 1-1 hole, spring shaft 2 is fastened on the knife bar 1 by nut 6, regulate the collapsing length of knife bar inner spring axle by adjusting nut, riveted joint has oilstone holder 4 on the other end of spring shaft 2, is fixed with oilstone 5 in the oilstone holder 4.

The utility model user mode, see also Fig. 3, spring shaft 2 is packed into and is riveted tightly after the oilstone holder 4 and polish the surface, oilstone 5 usefulness bonding agents are bonded in the oilstone holder 4, then spring 3 are contained on the spring shaft 2, and the knife bar 1 of together packing into, at this moment, can be according to workpiece to be processed 7 endoporus gradients, regulating spring axle 2 stretches out the gradient that the different length of knife bar 1 is regulated oilstone holder 4, adjusts the back and tightens with nut 6.In the process, can regulate thrust automatically by spring 3, and fine setting oil holder 4 gradients.Therefore the utility model not only guarantees to regulate thrusts automatically by spring 3 in the feed process, has not only guaranteed the cone face process precision in process of production but also has satisfied the requirement of surface roughness; Simultaneously, little, the convenient disassembly of the utility model volume, the part of the different taperings of suitable processing.
