Honing feed expansion tool mechanism

Abstract

The invention relates to a honing feed expansion tool mechanism, which comprises an expansion tool mandril and a driving device, wherein the expansion tool mandril extends along the vertical direction and can rotate around the central axis of the expansion tool mandril, and the driving device is used for controlling the expansion tool mandril to move along the vertical direction; the driving device comprises a power source, a lead screw and a push plate, wherein the lead screw extends along the vertical direction and is driven to rotate by the power source, and the push plate is sheathed on the lead screw and can move along the vertical direction with the rotation of the lead screw; the upper part of the expansion tool mandril is rotatably connected with the push plate, and can move along the vertical direction together with the push plate. The honing feed expansion tool mechanism disclosed by the invention has the beneficial effects that the structure is reasonable, the accurate operation of all components can be guaranteed better, and quantitative feed control, constant-pressure feed control and constant-pressure quantitative feed control are realized; the honing feed expansion tool mechanism disclosed by the invention is integrated and modular in integral structure, easier to process and assemble, light on the whole, high in precision and strong in universality.

Description

technical field [0001] The invention relates to a honing feed expansion mechanism. Background technique [0002] In the past, the feed expansion mechanism of honing machine tools used springs or manual twisting of threaded sleeve ejector rods or hydraulic cylinders to eject the ejector rods. The former two cannot obtain accurate constant-pressure feed, cannot continue to feed, and require manual labor. Manual control, the feeding method of the hydraulic cylinder driving the ejector pin can only realize constant pressure honing, none of the three feeding methods can realize quantitative feed honing, let alone constant pressure-quantitative feed honing, the one-time ejection of the ejector rod There is no speed control or ejection control during the ejection action until the honing stone is in contact with the workpiece. The action is too rough and simple, which may easily cause the honing stone to chip, the workpiece to be stuck, or even twist the honing head and honing rod. ...

[0002]In the past, the feed expansion mechanism of honing machine tools used springs or manual twisting of threaded sleeve ejector rods or hydraulic cylinders to eject ejector rods. The former two could not be obtained. Accurate constant pressure feeding cannot be continuously fed, and manual control is required. The feeding method of the hydraulic cylinder driving the ejector pin can only realize constant pressure honing. None of the three feeding methods can realize quantitative feeding honing, let alone Re
