Abstract
The invention discloses drilling equipment with primary and secondary drill bits. The drilling equipment drills holes through the primary drill bit and the secondary drill bit which are arranged together in a sleeved mode, namely the drill bit with the smaller diameter is sleeved with the drill bit with the large diameter. When the drilling equipment works, the drill bit with the small diameter is firstly driven to carry out positioning dotting, then the drill bit with the large diameter is driven to follow up hole drilling, meanwhile, the drill bit with the small diameter is located in front of the drill bit with the large diameter by a certain distance all the time and is stopped until the drill bit with the small diameter reaches a preset depth, and the drill bit with the large diameter keeps working until the preset depth is reached. Due to the facts that the positioning of the drill bit with the small diameter is accurate and drilling holes with small diameters are machined in advance, the drill bit with the large diameter can drill needed large bore diameters according to the small bore diameters, and drilling efficiency is improved while accurate positioning is guaranteed.
Description
Technical field
The present invention relates to the Drilling operation technical field, relate in particular to a kind of rig with primary-secondary drill.
Background technology
Drilling machine is to utilize the instrument harder, sharper keen than object by the mode of rotary cutting or rotary squeezing, stays machinery and the equipment general designation in cylindrical hole or hole on object, also referred to as rig, puncher, perforator or through-hole machine etc.When some sophisticated product is holed, need to get into accurate hole depth, for common drilling machine, can only stop after getting into certain depth and observe, to prevent from holing dark or the degree of depth is inadequate.
In order to increase work efficiency and the precision of drilling depth, the numerical control automatic drilling machine has appearred, the drive motors of its drill bit is electrically connected to numerical control unit, and first material require processing hole depth data to be processed are input in numerical control unit, numerical control unit is holed according to this hole depth, can guarantee the levels of precision of drilling depth, and reduce the artificial inefficiency problem of bringing that participates in.
In prior art, the larger boring of some material require processing diameter to be processed, for example surpass the boring of 5 millimeters, therefore, needs to use the drill bit of corresponding diameter to be holed; And the major diameter drill bit is in when boring, because contact area is larger, cause locating inaccurate, and frictional force is larger, the boring consumed power is larger.
Summary of the invention
In order to solve the technical problem existed in background technology, the present invention proposes a kind of rig with primary-secondary drill, to improve the boring positioning precision, and reduce the power consumption of holing.
A kind of rig with primary-secondary drill that the present invention proposes comprises:
Base;
Fixture, be arranged on described base, for treating rapidoprint, gripped;
Guide pillar, be arranged on described base;
The first motor, be arranged on described guide pillar, and can move up and down along guide pillar;
The second motor and the 3rd motor, be arranged on described the first motor by bracing frame respectively;
Female drill bit, be electrically connected to described the second motor;
Sub-drill bit, be electrically connected to described the 3rd motor; And described female drill sleeve is located at outside described sub-drill bit;
Numerical control unit, with described the first motor, described the second motor and described the 3rd motor, be electrically connected to respectively, controlling described the 3rd motor drives described sub-drill bit to position to get ready, then control described the second motor and drive described female drill bit follow-up boring, and described sub-drill bit is positioned at the front predeterminable range of described female drill bit, until described sub-drill bit reaches predetermined depth stop after, described female drill bit works on and arrives this desired depth.
Preferably, described predeterminable range is 4 to 6 millimeters.
Preferably, described the second motor is arranged on described the first motor by bracing frame, and described the 3rd motor is arranged on described the second motor.
Preferably, described sub-drill bit outer wall and described female drill bit through-hole wall closely cooperate.
In the present invention, by the primary-secondary drill be set-located, holed, the outer large drill bit of sheathed diameter of the drill bit that both diameter was little, during work, at first driving small diameter drill bit to position gets ready, then drive major diameter drill bit follow-up boring, guarantee that small diameter drill bit is positioned at major diameter drill bit distance the last period all the time simultaneously, until small diameter drill bit reaches predetermined depth stop after, till the major diameter drill bit works on and arrives this desired depth.Due to the registration of small diameter drill bit, and process in advance small-bore boring, the large aperture that the major diameter drill bit can need along this small-bore processing, both guaranteed accurate positioning, improves again drilling efficiency.
