Owing to adopted technique scheme, make to become a reality with engine lathe processing circular cone internal thread, this lathe structure compactness, easy to operate.The order of classes or grades at school output is for can reach 100, and product percent of pass can reach 98%.The production efficiency height, production cost is low, and constant product quality is particularly useful for the processing that petroleum industry is made small-bore circular cone internal thread.
Description of drawings
Fig. 1 is the structural representation of facing of the present utility model.
Fig. 2 is a plan structure schematic diagram of the present utility model.
Fig. 3 is that the A of Fig. 2 is to partial enlarged drawing.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
The utility model is that improved position is: the invariant position of lathe saddle, the knife rest on the lathe saddle top of dismantling, knife rest small slide plate and middle slide plate split out middle slide plate leading screw, nut and handle on the lathe saddle to the improvement of existing lathe.Structure of the present utility model by the body of lathe bed, is positioned at the lathe guide rail 2 on the lathe bed referring to accompanying drawing 1-2, and the lathe saddle 1 on bed ways top is made up of thrust stand 30, the spring pressure adjustment cover 20 thrust assemblies of forming etc.As shown in Figure 1, slide 33 is installed on the lathe guide rail 2, is fastened on the lathe bed with bolt 13, clamping plate 14.Gauge finder 26 is housed on the slide 33, and gauge finder 26 can rotate around axle 31 by the needs of turning taper angle, and is fastening with bolt 28 after angle mixes up.The slide plate 3 that floats is installed on the lathe saddle 1, and cursor slide 15 is equipped with on the right side of the slide plate 3 that floats, and is fastening with bolt 32.The right-hand member of cursor slide 15 is equipped with on roller shaft 11, the roller shaft 11 suit roller 12 and connects as one with unsteady slide plate 3.Spacing bracing frame 4 is installed in the inboard of lathe saddle 1, and is fixing with screw 18.Install on the spacing bracing frame 4 and adjust bolt 17 and locknut 16, be used for adjusting the shift motion of unsteady slide plate 3.Middle slide plate 6 is installed on the top of unsteady slide plate 3, with the gap of screw 29 adjustment middle slide plate leading screws 24 with nut 25, middle slide plate 6 is slided on unsteady slide plate 3.The top of middle slide plate 6 is equipped with small slide plate 10, and knife rest 9 is connected with small slide plate 10, and the internal threading that special-purpose internal thread machine folder is installed on the knife rest 9 is pressed from both sides guide rod 7 with machine, and internal threading is fastening with machine folder guide rod 7 usefulness screws 8.As shown in Figure 3, internal threading is equipped with the machine folder inside chaser sheet 34 of cutted thread with the front end of machine folder guide rod 7, and machine folder inside chaser sheet 34 usefulness screws 35 are fastening.
As Fig. 2, by thrust stand 30, bolt 19, spring pressure adjustment cover 20, locknut 21, compression spring 22 with set upright core bar 23 and form the thrust assembly.In the outside of lathe saddle 1 thrust stand 30 is housed, is fixed on the saddle with bolt 19.Two spring pressure adjustment covers 20 and locknut 21 are housed on the thrust stand 30, are adorning compression spring 22 in the spring pressure adjustment cover 20 and setting upright core bar 23.Be close to gauge finder 26 and certain pressure is arranged by the roller 12 that the pressure of adjusting compression spring 22 is connected the slide plate 3 that floats.Gauge finder 26 can rotate around axle 31 by the needs of turning taper angle, and is fastening with bolt 28 after angle mixes up.Middle slide plate leading screw 24, handle 5 are contained in the slide plate 3 that floats fastening with screw 27, and middle slide plate leading screw 24 is connected with middle slide plate 6.
