Abstract
The utility model discloses a manual centre frame is used to lathe that moves locate function to tape spool, it includes support body down, be provided with the axial positioning device down on the support body, the axial positioning device includes the vertical spacing post that sets up support body semicircle center department under in, rotates and sets up the gyro wheel that is used for contacting the bent axle thrust surface in spacing styletable portion to and set up the housing screw that is used for positioning roller in spacing styletable portion. The utility model discloses the coincidence of location benchmark and design standard has reduced positioning error in the time of can guaranteeing turning bent axle stub end, has guaranteed processingquality, has avoided axial positioning for the damage that the bent axle thrust surface brought, can effectively improve the machining precision.
Description
Technical field
The utility model relates to the centre frame technical field of lathe, especially relates to a kind of lathe with axially moving positioning function and moves centre frame.
Background technology
In the processing of Engine Industry crankshaft turning, centre frame is absolutely necessary machine tool accessory.Centre frame is all be used as radial location and add to strengthen part to be processed rigidity man-hour usually, and without axial positioning function, the axial location therefore during crankshaft turning realizes by the chuck be arranged on headstock.During turning bent axle big end surface, gripper chuck leans on the little head end of bent axle, the main shaft of the contiguous major part of center rest support.Now the axial location benchmark of turning bent axle is little end surface, and the design basis of bent axle big end surface axial dimension is the main shaft thrust surface of adjacent stub end, therefore design basis and positioning datum do not overlap, add positioning datum (little end surface) and design basis (thrust surface) distant, create larger position error, cannot ensure that the bent axle big end surface axial dimension after processing reaches designing requirement.
Utility model content
The utility model overcomes shortcoming of the prior art, provides a kind of lathe that effectively can improve the axial dynamic positioning function of band of machining accuracy and moves centre frame.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
Lathe with axially moving positioning function moves a centre frame, for location during Crankshaft Machining, comprises lower frame; Described lower frame is provided with axial direction positioning device, described axial direction positioning device comprises the limited post being vertically arranged at lower frame semi arch center, rotate and be arranged at limited post end for contacting the roller of crankshaft thrust face, and be arranged at the housing screw of limited post end for positioning roller.
Preferably, described limited post is threaded with lower frame.
Preferably, described limited post and lower frame are welded to connect.
Preferably, described limited post is made up of stainless steel.
Preferably, described roller is installed on limited post by bearing.
Compared with prior art, the utility model tool has the following advantages:
When the utility model can guarantee turning bent axle stub end, positioning datum and design basis overlap, and reduce position error, ensure that crudy, avoid the damage that axial location is brought to crankshaft thrust face.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the sectional view of A-A in Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not paying the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The lathe that band shown in Fig. 1 and Fig. 2 axially moves positioning function moves centre frame, adds the location in man-hour, comprise lower frame 1 for bent axle 10; Described lower frame 1 is provided with axial direction positioning device, described axial direction positioning device comprises the limited post 2 being vertically arranged at lower frame 1 semi arch center, rotate and be arranged at limited post 2 end for contacting the roller 3 of bent axle 10 thrust surface, and be arranged at the housing screw 4 of limited post 2 end for positioning roller 3.
Wherein, described limited post 2 is threaded with lower frame 1, obviously can also be welded to connect.Described limited post 2 preferably adopts stainless steel to make.Described roller 3 is installed on limited post 2 preferably by bearing.
When the utility model can guarantee turning bent axle stub end, positioning datum and design basis overlap, and reduce position error, ensure that crudy, avoid the damage that axial location is brought to crankshaft thrust face.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
