Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description of the embodiments, structures, features and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments.

Example 1

As shown in fig. 1-3, the present embodiment provides an adjustable flexible processing apparatus for inner bore honing and polishing, which includes a honing rod 1, elongated counter bores 8 symmetrically disposed on the side wall of the honing rod 1, an abrasive 5 installed in the counter bores 8, mounting holes 6 disposed in the counter bores 8 along the radial direction of the honing rod 1, and springs 7 disposed in the mounting holes 6, wherein two ends of the springs 7 respectively contact with the abrasive 5 in the corresponding counter bores 8 to apply an outward acting force to the abrasive 5.

Preferably, the abrasive 5 is a common abrasive strip or a diamond abrasive strip and is used for cutting and processing the allowance of the inner hole.

In order to maintain the stability of the acting force of the spring 7, two mounting holes 6 are arranged at two ends of the counter bore 8 respectively.

A long hole 4 is opened at one end of the honing rod 1 along the axial direction thereof, and a through hole 9 arranged along the radial direction of the honing rod 1 is communicated with the inner side end of the long hole 4, and the through hole 9 is opened to the outer side wall of the honing rod 1. This makes it possible to feed lubricating fluid through the elongated hole 4 to the vicinity of the abrasive position for lubrication and cooling of the working surface and for discharge of scrap during honing.

Example 2

In this embodiment, an extension rod 2 is welded to one end of the honing rod 1, a fitting hole 3 corresponding to the long hole 4 is formed in the extension rod 2, one end of the fitting hole 3 is a lubricating liquid interface, and the lubricating liquid interface is communicated with a hydraulic pump and a pipe device, as shown in fig. 1, so that the lubricating liquid can be pumped.

The connecting surface of the extension rod 2 and the honing rod 1 is provided with corresponding grooves and projections.

The whole length is prolonged by the extension rod 2, the inner hole with a large length-diameter ratio can be honed, and more use environment requirements can be met.

Example 3

In this embodiment, a groove 12 is formed on the surface of the module 5, an annular groove 11 is correspondingly formed on the side wall of the honing rod 1, and the inclined coil spring 10 is arranged in the groove 12 and the annular groove 11, as shown in fig. 4 and 5, after the inclined coil spring 10 is installed in place, the inclined coil spring 10 is lower than the outer surface of the abrasive material 5, so that the normal processing effect of the abrasive material 5 is not affected. The inclined ring spring 10 exerts inward radial force on the abrasive 5 smaller than outward radial force exerted by the spring 7 on the abrasive, and the structure has the advantages that on one hand, the supporting force of the spring 7 is reduced, so that the radial force between the inner hole of the workpiece and the abrasive is reduced, the roughness of the inner hole after honing is better, the straightness is more accurate, on the other hand, after the honing head leaves the inner hole of the workpiece, the abrasive 5 cannot fall under the action of the inclined ring spring 10, and the installation and storage are convenient. The radial force between the inner hole of the workpiece and the oilstone can be changed by replacing different springs 7 and inclined ring springs 10, so that the machining with different roughness is realized.

The utility model discloses can process on the ordinary lathe, the one end mountable of whole device is on lathe tool rest, and the honing process of hole is realized through the rotation of planker round trip movement and main shaft in the lathe. Meanwhile, the spring is utilized to exert an outward acting force on the grinding material, so that the size of the inner hole and the honing force can be controlled, and the form and position tolerance and the surface roughness of the inner hole are ensured.
