Abstract
The utility model relates to a spherical drill with cutting fluid. The spherical drill with cutting fluid comprises a twist drill, wherein one end of the twist drill is a drill bit. The head of the drill bit is spherical. A concave groove used to store cutting fluid is arranged at the upper end of the twist drill. The concave groove is sealed through a plunger. An oil outlet is arranged inwards on the drill bit. A transfer channel is arranged between the concave groove and the oil outlet. An anterior angle of the drill bit is 3 degrees to 6 degrees and a relief angle of the drill bit is 2 degrees to 3 degrees. According to the spherical drill with cutting fluid, a spherical drill is adopted to drill a spherical hole easily and simply. The cutting fluid is stored in the concave groove and the cutting fluid flows downwards along the transfer channel during work. The cutting fluid can be provided during drilling and grinding. The spherical drill with cutting fluid has the advantages of being simple, high in work efficiency and high in safety performance.
Description
Technical field
The utility model relates to a kind of brill, and a kind of sphere of drilling sphere hole bores specifically.
Background technology
In a lot of the application, the Kong Caineng that end of formation is planar base surface in workpiece meets the requirements.At present, the cutting element of many types and drilling system are developed in the application of the flat hole drill of processing.Prior art design processing sphere hole need to use different-diameter drill bit, in order to improve the quality on surface, workman schoolmate when operation can add the cutting fluid of some greasy properties, but needs drilling can not carry out with adding between the cutting fluid, so relatively loses time.
Summary of the invention
In order to address the above problem, the utility model provides a kind of sphere of drilling sphere hole to bore.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
The utility model is that a kind of sphere with cutting fluid bores, comprise fluted drill, one end of fluted drill is drill bit, the head of drill bit is set to sphere, the groove of storage cutting fluid is set in the upper end of fluted drill, groove seals groove by piston, inwardly is provided with an oil outlet on drill bit, is provided with transfer passage between groove and oil outlet.
Further improvement of the utility model is: the anterior angle of drill bit is 3 °-6 °, and the relief angle of drill bit is 2 °-3 °.
The beneficial effects of the utility model are: sphere of the present utility model bores and is used for the drilling sphere hole, simple and convenient, place cutting fluid in the spill, cutting fluid work in along conveyance conduit to dirty, in drilling, given like this cutting fluid, simple and convenient, to increase work efficiency, security performance is high.
The utility model is simple in structure, and is easy to make.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
In order to deepen that understanding of the present utility model is described in further detail the utility model below in conjunction with drawings and Examples, this embodiment only is used for explaining the utility model, does not consist of the restriction to protection domain of the present utility model.
As shown in Figure 1, the utility model is that a kind of sphere with cutting fluid bores, and comprises fluted drill 1, and an end of described fluted drill 1 is drill bit 2, and the head of described drill bit 2 is set to sphere, and the anterior angle that makes described drill bit 2 is 3 °-6 °, and the relief angle of described drill bit 2 is 2 °-3 °.The groove 3 of storage cutting fluid is set in the upper end of described fluted drill 1, and described groove 3 seals groove 3 by piston, inwardly is provided with an oil outlet 4 on described drill bit 2, is provided with transfer passage 5 between described groove 3 and described oil outlet 4.When the larger hole of drill diameter, the service life of boring in order to prolong sphere, can slightly bore with common drill bit first, then creeping into the row essence with sphere bores, cutting speed when boring drilling with height steel ball face, general steel are 5-10m/min, in the process of cutting, constantly give cutting fluid, guaranteed the quality of work piece surface.
