Abstract
The invention discloses a drill head structure for a knapping machine. The drill head structure for the knapping machine comprises a main drill head, a sleeve surrounding the main drill head and a power mechanism which drives the main drill head. The free end of the main drill head is provided with a positioning drill head. The diameter of the positioning drill head is smaller than the diameter of the main drill head. The free end of the positioning drill head is in a cone shape. According to the technical scheme, a groove which serves as a work station can be obtained on the surface of stone in advance, the main drill head can work on the work station, the working efficiency is improved, and the operating labor hours are greatly decreased.
Description
Technical field
The present invention relates to path formation machinery apparatus field, especially relate to a kind of drill bit structure of knapping machine.
Background technology
Knapping machine is when laying ground, smooth conventional machinery equipment is carried out to the ground being covered with stone or hard object, stone, by the rotation of self drill bit and power drive, is divided into the stone varied in size by usual knapping machine, thus reach can the requirement of smooth laying ground.
In prior art, jump situation can be often there is when using knapping machine to cut a hole disconnected process to stone, although namely owing to being positioned on stone the inaccurate drill bit that causes in the location of stone, drill bit meeting landing stone one place during driving bit, both the operant level of operator had been tested, also considerably increase the man-hour of operation simultaneously, be unfavorable for economic principle.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the object of the invention is the drill bit structure proposing a kind of knapping machine.
As the first embodiment, the invention provides a kind of drill bit structure of knapping machine, comprise: main drill bit, hold the sleeve of described main drill bit, drive the actuating unit of described main drill bit, the free end of described main drill bit is provided with location drill bit, and the diameter of described location drill bit is less than the diameter of described main drill bit, and the free end of described location drill bit is tapered.
On the basis of the first embodiment, as the second embodiment, between the described actuating unit of described location drill bit and described main drill bit, be provided with reducer.
On the basis of the first embodiment, as the third embodiment, be provided with the screw thread matched between described location drill bit with described main drill bit, described location drill bit can extending radially out and withdrawal along described main drill bit.
The drill bit structure of a kind of knapping machine provided by the present invention, by arranging location drill bit, when being fixed on stone by drill bit, location drill bit can in advance on stone the place of offering locate aperture, when then driving main drill bit to carry out rotary operation, just can ensure that main drill bit there will not be jump situation, substantially increases the accuracy of location, save working hour.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the drill bit structure that the embodiment of the present invention provides.
Detailed description of the invention
The beneficial effect of the technical problem solved to make the present invention, the technical scheme of employing and generation is clearly understood, below in conjunction with drawings and Examples, the present invention is described in further detail, be to be understood that, specific embodiment described herein only for explaining the present invention, is not intended to limit the present invention.
It should be noted that, when element is called as " being fixed on " or " being arranged at " another element, it can directly on another element or may there is centering elements simultaneously, " being connected to " another element when an element is called as, it can be directly connected to another element or may there is centering elements simultaneously.
Particularly, as shown in Figure 1, a kind of drill bit structure of knapping machine, comprise: main drill bit 1, hold the sleeve 2 of main drill bit 1, drive the actuating unit 3 of main drill bit 1, the free end of main drill bit 1 is provided with location drill bit 4, the diameter of location drill bit 4 is less than the diameter of main drill bit 1, and the free end of locating drill bit 4 is tapered.
A groove can be anticipated out in the surface of stone by arranging of this location drill bit 4, just can ensure to rotate in this groove when rotating main drill bit 1 and carrying out operation, stone is cut smoothly, thus reduces the man-hour expended of operator, be also conducive to the life-span of improving main drill bit 1.
Particularly, reducer 5 is provided with between location drill bit 4 and the actuating unit 3 of main drill bit 1, location drill bit 4 between main drill bit 1 because the cause of reducer 5 can obtain different rotating speeds, under normal circumstances, the rotating speed of location drill bit 4 can be greater than the rotating speed of main drill bit 1, can go out working position in stone surface pretreatment fast, main drill bit 1 reaches the object cutting off stone mainly through self gravity and rotating speed.
Particularly, location drill bit 4 is provided with between main drill bit 1 screw thread matched, location drill bit 4 can extending radially out and withdrawal along main drill bit 1, the helicitic texture cooperatively interacted makes location drill bit 4 can regulate degree of stretching out between the two according to the complexity of Work places, more effective raising operating efficiency with main drill bit 1.
These are only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement or improvement etc., all should be included within protection scope of the present invention.
