Abstract
The utility model relates to a straight shank separated combined finial, comprising a finial composed of a positioning shank and a demising surface. The front end of the demising surface is provided with a central finial hole, and the positioning shank is in a column shaped structure. A positioning fixture is also provided between the positioning shank and the demising surface. The utility model also comprises a taper shank matched with the positioning shank of the finial. The center of the taper shank is provided with a central positioning hole which shares a same center with the taper shank, and the big end of the taper shank is also provided with a positioning through slot which shares the same center with the taper shank. The utility model arranges the finial and the taper shank as separated structures, so that by aligning the positioning slot parallel to the guide rail of the machine tool, a grinding wheel does not collide with the demising surface of the finial during the working process. As the abraded finial adopts a straight shank, by cutting off the abraded central finial hole and then aligning the positioning straight shank and re-striking a central finial hole, the finial can continue to be used without affecting the processing precision. When the finial is changed, instead of withdrawing the whole taper shank, withdrawing the finial is only required, and thus the abrasion to the machine caused by changing the finial is reduced.
Description
Technical field
The utility model relates to a kind of circle mill frock clamp, and particularly a kind of staight shank separate type combination is top.
Background technology
Existing circle mill processing usefulness top generally is divided into steel part and the carbide alloy head is positive and negative top, and they all are to adopt taper fit, generally are divided into Mohs 1---Mohs 6.Their advantage is that taper fit is relatively more accurate, and ratio of precision is higher, is difficult for rotation in Grinding Process.But when the processing diameter is the punch part of Φ below 1, traditional toply can not satisfy the production demand, main cause be following some: 1, since processing diameter of part smaller, so just cause the tradition top step down to face the wall and meditate approach top easy wearing and tearing in the High-speed machining process, can not normally use; 2, since traditional top employing be taper fit, its top overmoving surface is difficult to guarantee keep vertical with machine tool guideway when the processing small part, the process medium plain emery wheel will wear tip overmoving surface, in the grinding overmoving surface, cause the distortion of clamping workpiece, influence the workpiece machining accuracy; 3, top after the wearing and tearing since thereafter handle be tapering, be difficult to reclaim again and to utilize, cause whole scrapping, strengthened processing cost, cause waste; 4, the frequent top lathe that can strengthen of replacing weares and teares.
Summary of the invention
The object of the present invention is to provide a kind of can cutting down finished cost, reduce top wearing and tearing, reduce and change top frequency, and can carry out secondary recovery and utilization, guarantee that the staight shank separate type combination of manufactured parts processing progress is top.
For achieving the above object, the technical solution adopted in the utility model is: comprise by positioning handle and overmoving surface constitute top, front end at overmoving surface is provided with the center center hole, be characterized in, positioning handle is a cylindrical structural, and it is flat also to be provided with a location between positioning handle and overmoving surface, and it also comprises a taper shank that matches with top positioning handle, offer a center positioning hole concentric at the center of taper shank, also be provided with a location groove concentric with taper shank at the big end of taper shank with taper shank.
Another characteristics of the present utility model are: also offer a locating hole that is connected with the location groove on the taper shank.
Because the utility model is top and taper shank is set to the branch body structure, parallel by centering location groove with the guide rail of lathe, just can not bump against at the process medium plain emery wheel with top overmoving surface; Top after the wearing and tearing be because what adopt is staight shank, as long as center center hole excision that will wearing and tearing, will locate the staight shank centering then after, hit heart center hole again and just can continue use, do not influence machining accuracy; Change when top as long as withdraw from, and do not need whole taper shank is withdrawed from, so just reduced to change top wearing and tearing for lathe with top.
Description of drawings
Fig. 1 is the structural representation of the utility model taper shank 1, and wherein Fig. 1 (a) is the front view of taper shank 1, and Fig. 1 (b) is the side view of Fig. 1 (a);
Fig. 2 is the structural representation of the utility model top 9, and wherein Fig. 2 (a) is top 9 front view, and Fig. 2 (b) is the side view of Fig. 2 (a).
The specific embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are described in further detail.
Referring to Fig. 1,2, the utility model comprise by cylindrical structural positioning handle 7 and overmoving surface 2 constitute top 9, and with top 9 taper shanks that match 1, overmoving surface 2 front ends top 9 are provided with center center hole 3, between positioning handle 7 and overmoving surface 2, also be provided with a location flat 8, offer a center positioning hole 5 concentric with taper shank 1 at the center of taper shank 1, also be provided with a location groove 4 concentric at the big end of taper shank 1, also offer a locating hole 6 that is connected with location groove 4 on the taper shank 1 with taper shank 1.
In use top 9 location staight shank 7 is cooperated with the centre of location hole 5 of taper shank 1, and top 9 location flat 8 cooperates with the big end location groove 4 of taper shank 1, parallel by centering location groove 4 in taper shank 1 installation process like this with the guide rail of lathe, just can not bump against at the process medium plain emery wheel with top overmoving surface 2.Location groove 4 on the taper shank 1 can also guarantee that top 9 can not rotate in process.The locating hole of offering on taper shank 16 can have been strengthened top 9 reliability, secondary utilizes again: top 9 after the wearing and tearing are location staight shanks 7 owing to what adopt, so as long as the center center hole 3 of wearing and tearing is excised, after will locating staight shank 7 centerings then, again hit heart center hole 3 and just can continue to use, do not influence machining accuracy.Reduce the wearing and tearing of lathe: change when top as long as top 9 on the taper shank 1 withdrawed from, and do not need whole taper shank 1 is withdrawed from, so just reduced to change top wearing and tearing for lathe.
