Embodiment Construction

[0016] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0017] see figure 1 , a micro-feeding device for a turning tool post according to the present invention can be applied to a milling machine to make it a turning-milling compound machine tool. The micro-motion feeding device for a turning tool post includes a screw rod 1, a fixed nut 2, a movable nut 3 Linear slide rail 4 and drive motor 5. The screw mandrel 1 is vertically arranged, and the screw mandrel 1 has an upper thread 6 and a lower thread 7 , the upper thread 6 and the lower thread 7 have the same direction of rotation, and the lead of the upper thread 6 is greater than that of the lower thread 7 . The fixed nut 2 is arranged on the screw mandrel 1 and is fixed on the milling head body 8 , and the fixed nut 2 is matched with the u...

Abstract

A tool bit holder micrometer feed device comprises a lead screw, a fixing nut, a movable nut, linear slide rails and a driving motor, wherein the lead screw is provided with two thread sections, and the two thread sections are in the same rotary direction but are different in lead; the fixing nut is arranged on the lead screw and matched with the thread section with the larger lead of the lead screw; the movable nut is arranged on the lead screw and matched with the thread section with the smaller lead of the lead screw; a tool bit holder is mounted on the movable nut; the linear slide rails are arranged in the axial direction of the lead screw in parallel; the movable nut is slidably connected with the linear slide rails through a nut sliding block; and a rotation output part of the driving motor is fixedly connected with the lead screw. Accordingly, the smaller the lead different of the two thread sections, the smaller the feed amount of the movable nut, and micrometer feed of the tool bit holder can be achieved more easily; and action response of the tool bit holder can be quite smooth.

Description

technical field [0001] The invention relates to the technical field of machine tools, in particular to an inching feed device for a turning tool post. Background technique [0002] The turning tool holder is used to clamp the turning tool, and the fretting performance of the turning tool holder is an important indicator of the accuracy of the lathe or the turning-milling compound machine tool. The feed of the tool post of the general machine tool is driven by a screw, and the accuracy of the feed is limited by the thread lead of the screw, so it is difficult to achieve a small feed, and the processing requirements for the screw thread are extremely high, so It is difficult to improve the fretting performance of the existing turning tool post at low cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an inching feed device for a turning tool holder which is easy to process, low in cost and good in inching perfo...
