Abstract
The utility model relates to a dual-purpose centre for lathes, composed of a centre body, a dual-purpose centre, a slide block, a latching pin, a spring, etc. The center is arranged in the center body through a bearing; the head section is a working portion composed of a cutting edge and a multilateral hinge edge; the slide block is connected with a handle into a whole body through a coupling shaft; the latching pin is arranged below the handle. When the dual-purpose centre for lathes is used, the latching pin is pressed to push the handle to cause the slide block to be inserted in a groove at the tail section of the centre and connected with the centre into a whole body, and the utility model can process centre holes; when the slide block is disengaged from the centre, the centre rotates with workpieces to effect the function of supporting workpieces. The utility model has the advantages of operating time saving and high work efficiency, and the dual-purpose centre for lathes is an ideal novel special centre for lathes.
Description
The utility model relate to a kind of can the working shaft-like centre bore and the lathe of supporting workpiece dual-purpose top.
At present during working shaft-like workpiece, at first centre drill to be contained in machining center hole in the tail stock drill point, then stop and unclamp fixedly that the gong silk retracts tailstock, withdraw from centre drill and change toply, again tailstock is pushed away and withstand workpiece and tighten fixedly that the gong silk carries out machining.Adopt this method, operation is cumbersome, and is time-consuming, and production efficiency is low.
The purpose of this utility model provides a kind of simplified operation process, increases work efficiency, can the working shaft-like centre bore, and lathe that again can supporting workpiece is dual-purpose top simultaneously.
The purpose of this utility model is achieved in that this lathe is dual-purpose and toply is made up of top body, dual-purpose top, slide block, lockweight and spring etc.Dual-purpose toply be installed in the top body by bearing, its head is a working portion, is made up of cutting edge and polygon hinge sword, tail end face is processed with groove.Slide block is arranged on dual-purpose top afterbody, and is complementary with the afterbody groove, is provided with spring at its rear side, and slide block is connected as a single entity by coupling spindle and handle.Lockweight is housed on the top body below handle and has microscler axis hole, lockweight is corresponding with the locating slot on the handle, and the coupling spindle that can move forward and backward is arranged in the microscler axis hole.
Adopt the utility model, can the machining center hole, can work as top use again, stable working is reliable, the life-span is long, overcome the tired lock program of past operator's a lot of replacing instrument and front and back push-and-pull tail stock, especially convenient especially to processing short-and-medium shaft-like work in batch, can save the operating time, obviously increasing work efficiency, is that desirable novel lathe special use is top.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the utility model structural representation.
Work schematic diagram when Fig. 2 is the utility model machining center hole.
As shown in Figure 1, dual-purpose top 10 are installed in the top body 2 by bearing 12, and this bearing can adopt taper roll bearing and thrust ball bearing with flat seat, also can adopt common radial ball bearing.What adopt in the present embodiment is two dish single-row radial ball bearings, and positioning retainer ring 11 is housed between the two bearings, and gland 9 is equipped with in the bearing outer end, and gland 9 is threaded with top body 2.
Dual-purpose top head is a working portion 15, is made up of cutting edge and polygon hinge sword.Cutting edge is mainly used in the machining center hole, and polygon hinge sword is mainly used in the location of machining center orifice angle and centre bore.Slide block 6 is arranged on dual-purpose top afterbody, and is complementary with the groove 13 of top afterbody.
On the top body 2 lockweight 7 is housed, lockweight 7 heads are corresponding with the locating slot 8 on the handle 4.Also have microscler axis hole 14 on top body 2, coupling spindle 5 is arranged in the microscler axis hole 14, one end and handle 4 pin joints or riveted joint, and the other end is threaded with slide block 6.The tail end of top body 2 also is equipped with plug 1.
During work, top body 2 is contained in the tail stock, depresses lockweight 7, driving handle 4 reaches make slide block 6 embed in the groove 13 of dual-purpose top afterbody, and by spring 3 slide block 6 are held out against, as shown in Figure 2.At this moment, top 10 and top body 2 be fixed as one, can carry out centre bore processing, played the effect of centre drill.
When slide block 6 was thrown off with top 10, the head of lockweight 7 entered in the locating slot 8 on the handle 4, and slide block 6 maintains static with top body 2, and top 10 with the workpiece rotation, plays top effect this moment.In the use, only need loading and unloading once, just can finish the machining center hole, play the effect of supporting workpiece simultaneously.
Claims (3)
1, a kind of lathe is dual-purpose top, comprises top body and dual-purpose top, it is characterized in that it also includes slide block, lockweight and spring, dual-purpose toply be installed in the top body by bearing, its head is a working portion, is made up of cutting edge and polygon hinge sword, and tail end face is processed with groove; Slide block is arranged on dual-purpose top afterbody, and is complementary with the afterbody groove, is provided with spring at its rear side, and slide block is connected as a single entity by coupling spindle and handle; Lockweight is housed on the top body below handle and has microscler axis hole, lockweight is corresponding with the locating slot on the handle, and the coupling spindle that can move forward and backward is arranged in the microscler axis hole.
