Description
Technical field
The utility model relates to a kind of device for locating drilling depth of driller.
Background technology
In existing design, the location of drilling depth of driller adopts the adjustment of sleeve backstay to realize more, in long use procedure, the parts such as tooth bar, sleeve, bearing of drilling rod can produce certain wearing and tearing, therefore, require high processing work for some borings, counterbore depth, its positioning precision cannot meet the demands.
Utility model content
For the problems referred to above, the utility model provides a kind of device for locating drilling depth of driller, the fast and easy location drilling degree of depth, improves positioning precision.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of device for locating drilling depth of driller, comprise sleeve and be arranged on the main shaft drilling rod on sleeve, it is characterized in that, the afterbody of described main shaft drilling rod is provided with thread Pilot hole, one belt wheel is fixed on outside sleeve by packing ring, one adjustable threaded rod is arranged on the afterbody of main shaft drilling rod by splined shaft, described adjustable threaded rod is connected with splined shaft by locking nut, described sleeve is inwardly provided with a cavity volume from afterbody, described cavity volume internal fixtion is provided with spring, described spring is connected with a dip stick, and the described dip stick other end is against the end face of locking nut.
Wherein, preferably, described dip stick is the cylindrical shape of metal material, or the cylindrical shape of plastic material.
Install the adjustable threaded rod of drilling depth, locking nut additional at the afterbody of main shaft drilling rod, namely the distance between adjusting nut and packing ring is the numerical value of drilling depth H, and due to the active force of spring, the dip stick moment shows the numerical value of drilling depth, greatly improves precision.During boring, frock and main shaft drilling rod move up and down simultaneously, and when nut moves to packing ring place, drilling depth puts in place, and cutter is return, and alignment quality is stablized, and positioning precision improves simultaneously.
The beneficial effects of the utility model are: the fast and easy location drilling degree of depth, improve positioning precision.Avoid in long use procedure, the parts such as tooth bar, sleeve, bearing of drilling rod can produce certain wearing and tearing.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of device for locating drilling depth of driller of the utility model;
The mark implication of accompanying drawing is as follows:
1: sleeve; 2: belt wheel; 3: packing ring; 4: splined shaft; 5: nut; 6: locking nut; 7: adjustable threaded rod; 8: main shaft drilling rod; 9: screw thread; 10: dip stick; 11: cavity volume; 12: spring.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, technical solutions of the utility model are described in further detail, to make those skilled in the art better can understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.
A kind of device for locating drilling depth of driller, as shown in Figure 1, the main shaft drilling rod 8 comprising sleeve 1 and be arranged on sleeve 1, the afterbody (right side in Fig. 1) of described main shaft drilling rod 8 is provided with screw thread 9 bottom outlet, one belt wheel 2 is fixed on outside sleeve 1 by packing ring 3, one adjustable threaded rod 7 is arranged on the afterbody of main shaft drilling rod 8 by splined shaft 4, described adjustable threaded rod 7 is connected with splined shaft 4 by locking nut 6, and namely adjustable threaded rod 7 is locked on splined shaft 4.
Described sleeve 1 from afterbody inwardly (namely in figure from right side to the left) be provided with a cavity volume 11, described cavity volume 11 internal fixtion is provided with spring 12, the i.e. leftmost side fixing spring 12 of cavity volume 11, the right-hand member of spring 12 is connected with a dip stick 10, in order to ensure the accuracy of drilling depth, a nut 5 is provided with in the side of the close cavity volume 11 of locking nut 6, described dip stick 10 other end is against on the end face of nut 5, the zero graduation line of dip stick 10 is positioned at nut 5 place, then namely the distance between nut 5 and packing ring 3 is the numerical value of drilling depth H.
Preferably, dip stick 10 is cylindrical, now, corresponding, cavity volume 11 is also cylindrical, and the radius of cavity volume 11 is slightly larger than the radius of dip stick 10, prevents dip stick 10 from bending, wherein, dip stick 10 can be the cylindrical shape of metal material, also can be the cylindrical shape of plastic material.
Wherein, preferably, nut 5 is round nuts 5, and packing ring 3 is rounded washers 3.
The adjustable threaded rod 7 of drilling depth, locking nut 6 is installed additional at the afterbody of main shaft drilling rod 8, namely distance between adjusting nut 5 and packing ring 3 is the numerical value of drilling depth H, and due to the active force of spring 12, dip stick 10 moment shows the numerical value of drilling depth, greatly improves precision.During boring, frock and main shaft drilling rod about 8 move simultaneously, and when nut 5 moves to packing ring 3 place, drilling depth puts in place, and cutter is return, and alignment quality is stablized, and positioning precision improves simultaneously.The fast and easy location drilling degree of depth, improves positioning precision.Avoid in long use procedure, the parts such as tooth bar, sleeve 1, bearing of drilling rod can produce certain wearing and tearing.
These are only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in the technical field that other are relevant, be all in like manner included in scope of patent protection of the present utility model.
