A Segment Feed Honing Head Device with Shape Deviation Compensation Function

Abstract

The invention relates to a sectional feeding honing head device with a shape deviation compensation function. The sectional feeding honing head device with the shape deviation compensation function comprises a main body, an inner spindle, an outer spindle, a main oilstone seat, an upper compensation oilstone seat and a lower compensation oilstone seat, wherein the inner spindle is installed in a hole of the outer spindle, the outer spindle is installed in a center hole of the main body, the main oilstone seat is installed in a main oilstone groove of the main body, the upper compensation oilstone seat and the lower compensation oilstone seat are installed in compensation oilstone grooves of the main body, the edges of the two ends of the main oilstone seat are respectively pressed by a retraction spring ring, the edges of the outer sides of the upper compensation oilstone seat and the lower compensation oilstone seat are respectively pressed by a retraction spring ring, the edges of the inner sides of the upper compensation oilstone seat and the lower compensation oilstone seat are pressed by retraction leaf springs, the upper compensation oilstone seat and the lower compensation oilstone seat are fixed by compensation oilstone fixing blocks, and a main oilstone and compensation oil stones are respectively installed on the corresponding oilstone seats. The sectional feeding honing head device with the shape deviation compensation function has the advantages that since the device itself has the shape deviation compensation function, under the situation that the back-and-forth movement trajectory of the honing head is unchanged, the shape deviation which occurs during machining can be compensated in real time and the shape accuracy of the honed inner bore can be guaranteed.

Description

technical field [0001] The invention relates to a honing head for inner hole honing, in particular to a segmented feed honing head device with a shape deviation compensation function. Background technique [0002] In today's engine cylinder bore precision manufacturing process, the platform honing process has been widely used. The honing of the engine cylinder hole is the last and most important process of the cylinder hole processing, which can ensure the final process index of the cylinder hole. Honing is a process of further processing the finished surface by using the whetstone embedded on the honing head. During the processing, the honing head makes continuous reciprocating linear and rotary motions, driving the whetstone to precisely cut the cylindrical hole material. It can be seen that the structure and motion performance of the honing head will inevitably affect the honing accuracy. [0003] In the current honing process, a prominent problem is that the shape devi...

However, the disadvantage of this compensation method is that it puts forward extremely high requirements on the parameters such as the reciprocating stroke control accuracy and repeatability of the honing machine spindle, and at the same time inevitably increases the complexity of the spindle motion and control mechanism and the design and manufacture. cost; and this compensation method will greatly increase the honing processing time, which is not conducive to the improvement of production efficiency and the maintenance of production beat

For example, Chinese patent CN202336793U discloses an adjustable honing head mechanism, which is composed of a honing head, a diamond honing bar, an adjustment pad, an adjustment nut, and a positioning frame; the middle part of the honing head is a cylinder, and there are threaded joints at both ends of the cylinder. There are honing stick installation grooves penetrating left and right on the front and rear sides of the outer surface; two diamond honing sticks are respectively installed in the two honing stick installation grooves, and a positioning frame is arranged at both ends of each diamond honing stick, and two The adjusting nuts are matched with the threaded joints at both ends of the honing head respectively. An adjusting pad is arranged on the inner side of each adjusting nut, and the adjusting pad is pressed against the positioning frame to clamp the honing bar. , resulting in a large deviation in the processing size; the honing head is discarded after wear and tear, resulting in waste, but it does not involve direct compensation for the processing accuracy of the honing cylinder bore shape, roundness, cylindricity, etc.
