Abstract
The utility model relates to a cutter with spiral holes. The cutter with the spiral holes includes a cutter handle and a drill bit formed integrally with the cutter handle. Two through spiral holes are arranged in the cutter handle and the driller bit. The drill bit is composed of an upper drill bit and a lower drill bit. The lower part of the lower drill bit is provided with a water outlet. The outer diameter of the lower drill bit is smaller than that of the upper drill bit. A stepped blade is formed on a connection part of the upper drill bit and the lower drill bit. Each side of the stepped blade is provided with an auxiliary water outlet communicated with one spiral hole. The cutter with the spiral holes is used for processing stepped holes. By arranging the two through spiral holes, the water outlet and the auxiliary water outlet, contact area of cooling liquid and the cutter is enlarged, heat produced in a cutter-employing machining process can be reduced effectively. Besides, since the cooling liquid is ejected from the water outlet and the auxiliary outlets, water outlet pressure is increased, so that surface smoothness of a work piece after machining is improved appropriately.
Description
Technical field:
The utility model relates to the cutter in a kind of machining, relates in particular to the threaded hole cutter with cold hole in spiral.
Background technology:
At present, because the paces of mechanization degree development are very fast, requirement on machining accuracy to hole in being applied to machining is higher, the particularly processing to deep hole and shoulder hole,, according to actual conditions, produce one the cutter of length-specific according to the degree of depth in hole, but cutter carried out the cutting of workpiece in process at High Rotation Speed, a large amount of heat of its generation or the precision that affects cutter itself cause workpiece size to produce deviation, in the easy impaired life-span that affects of cutter, have increased production cost.
Summary of the invention:
The technical problem that the utility model solves is to provide a kind ofly to be guaranteed its axiality, and increases work efficiency for shoulder hole processing, realizes the threaded hole cutter to the step place of shoulder hole in the lump chamfered.
The technical scheme in the invention for solving the technical problem is: a kind of threaded hole cutter, comprise handle of a knife and with the drill bit of handle of a knife one, described handle of a knife and drill bit internal offer the threaded hole of two perforations, described drill bit is comprised of upper drill bit and lower drill bit, the below of described lower drill bit sets out water hole, the external diameter of lower drill bit is less than the external diameter of drill bit, the connecting portion of described upper drill bit and lower drill bit forms step sword, the side of described step sword is offered two auxiliary apopores, and each connects two described auxiliary apopores with a threaded hole.
Further, the side of described step sword is 90 ° of angles.
Further, the bottom surface of described lower drill bit is 90 ° of angles.
The beneficial effects of the utility model: this cutter is for processing shoulder hole, two threaded hole, apopore and the auxiliary apopore of its perforation, increased the contact area of cooling fluid and cutter, the temperature producing while more effectively reducing tool sharpening, and the cooling fluid penetrating from apopore and auxiliary apopore, its discharge pressure increases to some extent, thereby has also moderately improved the surface smoothness of the workpiece after processing.
Accompanying drawing explanation:
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram of lower drill bit of the present utility model bottom.
In figure: 1, handle of a knife 2, drill bit 21, upper drill bit 211, step sword 212, auxiliary apopore 22, lower drill bit 221, apopore 3, threaded hole.
The specific embodiment:
A kind of threaded hole cutter as illustrated in fig. 1 and 2, comprise handle of a knife 1 and with the drill bit 2 of handle of a knife one, described handle of a knife 1 and drill bit 2 inside offer the threaded hole 3 of two perforations, described drill bit 2 is comprised of upper drill bit 21 and lower drill bit 22, the below of described lower drill bit 22 sets out water hole 221, the bottom surface of described lower drill bit (22) is 90 ° of angles, the external diameter of lower drill bit 22 is less than the external diameter of drill bit 21, the connecting portion of described upper drill bit 21 and lower drill bit 22 forms step sword 211, further, the side of described step sword 211 is 90 ° of angles, the side of described step sword is offered two auxiliary apopores 212, two described auxiliary apopores 212 respectively connect with a threaded hole 3.
This cutter is for processing shoulder hole, two threaded hole 3, apopore 221 and the auxiliary apopore 212 of its perforation, increased the contact area of cooling fluid and cutter, the temperature producing while more effectively reducing tool sharpening, and the cooling fluid penetrating from apopore 221 and auxiliary apopore 212, its discharge pressure increases to some extent, thereby has also moderately improved the surface smoothness of the workpiece after processing.
It is emphasized that, it is more than better implementation column of the present utility model, not the utility model is done to any type of restriction in appearance, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
