Abstract
The utility model discloses a machine tool used for processing an over-long diameter ratio shaft which exceeds the standard of the machine tool. The machine tool comprises a machine tool body, a mainshaft box that is fixed at the front end of a table board of the machine tool body, three tailstock guide tracks that are fixed at the front part and the rear end of the table board of the machine tool body along the mainshaft direction, two tool holder guide tracks that are arranged on the table board of the machine tool body and parallel to the tailstock guide tracks, tailstocks that are arranged on the tailstock guide tracks and are capable of moving along the tailstock guide tracks and tool holders that are arranged on the tool holder guide tracks and do feed movement vertically and horizontally along two shafts, wherein, a rack that can be meshed and transmitted with a gear fixed at the bottom of the tailstock is fixed on the middle tailstock guide track of the three tailstock guide tracks, and the tailstock guide tracks and the tail ends of the rack are respectively connected with a section of additional tailstock guide track with effective length and an additional rack. The machine tool of the utility model that is used for processing the over-long diameter ratio shaft which exceeds the standard of the machine tool has the advantages that one machine with multiple functions can be realized, the utilization ratio of the machine tool can be improved and the production cost can be reduced, thereby adding a processing device for special parts in the mechanical industry.
Description
Technical field
The utility model relates to a kind of machining equipment, is specifically related to a kind of lathe that is used to process the over-long diameter ratio shaft of exceeding machine tool standard.
Background technology
Be unable to do without various mechanical processing machines in the machine-building, lathe is mainly used in various rotary surfaces of processing and end face, as the face of cylinder, taper seat, cannelure, the shaping surface of revolution, end face and various screw threads etc.Add man-hour, normally by workpiece rotatablely move and the feed motion of cutter realizes.Slender axles are meant the axial workpiece of the ratio of length L and diameter d greater than 20 (being L/d＞20), and the ratio of the length L of over-long diameter ratio shaft and diameter d is greater than 50 axial workpieces.All belong to over-long diameter ratio shaft as pull bar in the top working roll in the 16m three rolls plate bending machine, the 165MN hydraulic press etc.Existing processing major axis class lathe can not adapt to the processing of such over-long diameter ratio shaft.Processing major axis class lathe comprises lathe bed, head of a bed main spindle box, knife rest, tailstock, motor, transmission mechanism etc., lathe bed is provided with footstock guide and the tool guide that is parallel to each other, tailstock is located on the footstock guide, and knife rest is located on the tool guide between head of a bed main spindle box and the tailstock.Workpiece one end is by the chuck clamping on the head of a bed main spindle box, and the other end is done to support with one heart by the thimble on the tailstock, and knife rest is installed on the knife rest slide carriage, can drive lathe tool by the knife rest slide carriage and do longitudinal and transverse and diaxon feed motion simultaneously.Yet it is 15 meters major axis part that existing processing major axis class lathe can only be processed the longest.In order to reduce production costs, how on existing processing major axis class lathe, to process the longaxones parts that surpasses more than 15 meters, be the technical problem that the insider needs to be resolved hurrily.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency of existing equipment ability, and a kind of lathe that is used to process the over-long diameter ratio shaft of exceeding machine tool standard is provided, and it can enlarge the range of work of longaxones parts, has reduced production cost.
The technical scheme that realizes above-mentioned purpose is: a kind of lathe that is used to process the over-long diameter ratio shaft of exceeding machine tool standard, comprise lathe bed, be fixed on the main spindle box of lathe bed table top front end, be fixed on three footstock guides of the front portion and the rear end of lathe bed table top along major axes orientation, be installed on the lathe bed table top and the two piece tool guides parallel with footstock guide, the tailstock that is located on the footstock guide and can moves along footstock guide, be located on the tool guide and also can indulge, the knife rest of horizontal stroke and diaxon feed motion simultaneously, fix on one of the centre of described three footstock guides one can with the tooth bar of the meshed transmission gear that is fixed on the tailstock bottom, the tail end of described footstock guide and tooth bar also connects the additional footstock guide and the additional tooth bar of one section effective length respectively.
The above-mentioned lathe that is used to process the over-long diameter ratio shaft of exceeding machine tool standard, wherein, the length of described additional footstock guide and additional tooth bar is 8 meters.
The technical scheme of the lathe of the over-long diameter ratio shaft that is used to process exceeding machine tool standard of the present utility model, adopted and on machine tool, finished the structure transformation, promptly connected one section additional footstock guide at the footstock guide tail end that tailstock is installed, strengthened the shift motion of tailstock, thereby strengthened the range of work of axial workpiece, the machine tool that makes script can only process 15 meters long axle is increased to can process 23 meters major axis.Because the kind of workpiece is a lot, and the kind of lathe and platform number are limited, and the lathe that is used for the processing super long diameter ratio shaft of the present utility model can be realized one-machine-multi-function, improve the utilization rate of lathe, reduce production cost, increased a kind of process equipment of peculiar part for mechanical industry.
Description of drawings
Fig. 1 is the schematic diagram of the lathe of the lathe of the over-long diameter ratio shaft that is used to process exceeding machine tool standard of the present utility model;
Fig. 2 is the structural representation of the lathe medial bed of the over-long diameter ratio shaft that is used to process exceeding machine tool standard of the present utility model;
Fig. 3 is the vertical view of the lathe medial bed of the over-long diameter ratio shaft that is used to process exceeding machine tool standard of the present utility model.
The specific embodiment
In order to understand the technical solution of the utility model better, below by embodiment particularly and be described in detail in conjunction with the accompanying drawings:
The workpiece chuck that is provided with on the main spindle box 2 is attached with tailstock 5 holding workpieces 9, on the knife rest 6 lathe tool is installed, rotate together with workpiece 9 by main motor-driven main shaft, simultaneously, vertical motor-driven longitudinal feed mechanism, and cooperate crossfeed mechanism drive knife rest 6 together with lathe tool along coordinate in length and breadth with in length and breadth to coordinate feeding cutting, realization turning campaign.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as at connotation scope tailstock of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
