Abstract
The utility model relates to a lengthened end mill which has a simple structure and is convenient to machine to enable that the end mill can not only meet the machining requirements of the parts with deeper inner cavities but also ensure the machining precision. The lengthened end mill is characterized in that the lengthened end mill comprises an end mill and a lengthened shank; a through hole vertical to the axial direction of the shank of the end mill is formed on the shank; a blind hole is axially formed at one end of the lengthened shank; the end mill is inserted into the blind hole and the through hole is hidden in the blind hole; a hole corresponding to the through hole on the end mill is formed on the wall of the blind hole; connecting sheets are arranged in the upper and lower positions of the hole on the outer wall of the lengthened shank; a connecting strip is inserted into the hole and the through hole; and the two ends of the connecting strip are fixedly connected with the connecting sheets via bolts. The lengthened end mill is applicable to machining tools.
Description
Technical field
The utility model relates to a kind of slotting cutter, especially a kind of lengthening slotting cutter.Be applicable to machine tool.
Background technology
Slotting cutter is the cutter that the deep trouth on the box parts of a kind of machined grooves, step and various mutually perpendicular plane, particularly machined steel and cast iron is used.At present, when using slotting cutter to carry out Milling Process for the shell part inner chamber, because the individual part inner chamber is darker, normally used standard slotting cutter is subjected to the restriction of length, can't satisfy processing request.
Summary of the invention
The technical problems to be solved in the utility model is: at the problem of above-mentioned existence, provide a kind of lengthening slotting cutter simple in structure, easy to process, so that slotting cutter can satisfy the process requirements of the dark part of inner chamber, can guarantee machining accuracy again.
The technical scheme that the utility model adopted is: a kind of lengthening slotting cutter, it is characterized in that: have slotting cutter and add long handle, described slotting cutter shank has vertical its axial through hole, described long handle one end that adds axially has blind hole, interior described slotting cutter of plug-in mounting of blind hole and described through hole submerge in the blind hole, corresponding slotting cutter lead to the hole site is offered hole on the blind hole hole wall, be provided with brace at the upper-lower position that adds hole on the long handle outer wall, plug-in mounting one connection strap in described hole and the through hole, fixedly connected with brace through screw in these connection strap two ends.
Describedly add that blind hole depth is 1/2～2/3 of a slotting cutter shank length on the long handle.
The beneficial effects of the utility model are: the utility model is simple in structure, easily manufactured, slotting cutter is inserted into adds long handle, the integral body slotting cutter that extended, make slotting cutter satisfy the process requirements of the dark part of inner chamber, connection strap by a vertical slotting cutter axis is with slotting cutter and add long handle and firmly link together, guarantee slotting cutter and add long handle Stability Analysis of Structures between the two, guarantee that the slotting cutter machining accuracy is unaffected.
Description of drawings
Fig. 1 is the structural representation of embodiment.
Fig. 2 is the vertical view of embodiment.
The specific embodiment
As shown in Figure 1 and Figure 2, present embodiment is a kind of lengthening slotting cutter, comprises slotting cutter 1 and adds long handle 2.Wherein slotting cutter 1 shank has vertical its axial through hole.Add long handle 2 one ends and axially have blind hole, plug-in mounting slotting cutter 1 in the blind hole, and the through hole of slotting cutter 1 shank submerges in blind hole after plug-in mounting is finished.Corresponding slotting cutter 1 lead to the hole site is offered hole on the blind hole hole wall, and is equipped with brace 202 in the upper and lower position that adds hole on long handle 2 outer walls.The hole of blind hole hole wall both sides is communicated with slotting cutter 1 shank through hole, and plug-in mounting one connection strap 3 within it, fixedlys connected with brace 202 through screw 4 in these connection strap two ends.
Add long handle 2 in the present embodiment and be made up of different two sections of size diameter, wherein path section 201 diameters are identical with slotting cutter 1 shank diameter, and big footpath section diameter is 1.8 times of path section 201.Blind hole is opened in big footpath section.
The blind hole depth that adds in the present embodiment on the long handle 2 is 1/2 of slotting cutter 1 a shank length.
Certainly, above-mentioned explanation is not to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in scope of the present utility model, the variation of making, change and add or replace, all should belong to protection domain of the present utility model.
