The traditional drilling tool has many defects in the using process, for example, the traditional drilling tool needs to be provided with an auxiliary tool rest when being connected with a lathe, the worker is troublesome in the dismounting process, the production efficiency is reduced, and the production cost is increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a: the lathe center drilling tool is provided for solving the problem that the traditional drilling tool can be connected with a lathe only by using an auxiliary tool rest.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the lathe center drill tool comprises a center drill clamp, a drill rod and an annular connecting frame, wherein planes are arranged at the vertical two ends and the horizontal two sides of the connecting frame, connecting blocks are arranged on the planes, protrusions are arranged on the side walls of the connecting blocks, and the center drill clamp is fixed outside the protrusions.
As a further description of the above technical solution:
a plurality of connecting holes are formed in the front surface wall of the connecting frame.
As a further description of the above technical solution:
two locking bolts are symmetrically and slidably embedded in the connecting block relative to the center of the connecting block.
As a further description of the above technical solution:
and the planes at the vertical two ends and the horizontal two sides of the connecting frame are provided with bolt holes screwed with the locking bolts.
As a further description of the above technical solution:
the connecting frame and the connecting block are both made of No. 45 steel through heat treatment.
To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:
1. the utility model discloses in, the connecting block passes through the bolt hole and the locking bolt is fixed on the link, and the center drill clamp passes through the arch to be fixed on the connecting block, when installing the cutter, only needs to place the link on the knife rest of lathe, and bolt on the rethread knife rest and connecting hole on the link can be fixed the drilling rod, compare traditional cutter, saved the cost of vice knife rest and to the process of vice knife rest installation, simplified technology, make things convenient for more in daily use.
2. The utility model discloses in, the connecting block is provided with a plurality ofly altogether, and all is fixed with the drilling rod on every connecting block, and the variation in size of every drilling rod, when the drilling requirement in the face of equidimension not, the knife rest can drive the link and take place to rotate for the drilling rod that meets the requirements carries out the drilling operation, saves the process of artifical change drilling rod, has improved production efficiency.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: lathe center bores cutter, including center drill anchor clamps 5 and drilling rod 6, still include annular link 1, the vertical both ends and the horizontal both sides of link 1 all are equipped with the plane, and be provided with connecting block 2 on the plane, link 1 and connecting block 2 are made by 45 steel thermal treatment, hardness is higher, be provided with arch 4 on the lateral wall of connecting block 2, arch 4 and connecting block 2 formula structure as an organic whole, stability is higher, center drill anchor clamps 5 are fixed in arch 4's outside, the one end of center drill anchor clamps 5 presss from both sides tight arch 4, the other end presss from both sides tight drilling rod 6.
Specifically, as shown in fig. 1, a plurality of connecting holes 3 are formed in the front surface wall of the connecting frame 1, the connecting holes 3 are connected with the tool rest through bolts, and the connecting frame 1 has a guiding effect, can quickly correct the position of the connecting frame 1, and is convenient to install the connecting frame 1.
Specifically, as shown in fig. 3, the connecting block 2 is symmetrically and slidably embedded with two locking bolts 7 in the center, the locking bolts 7 are in clearance fit with the connecting block 2, bolt holes 8 screwed with the locking bolts 7 are formed in the planes of the vertical two ends and the horizontal two sides of the connecting frame 1, and the connecting block 2 can be fixed on the connecting frame 1 through the locking bolts 7 and the bolt holes 8.
The working principle is as follows: during the use, directly put link 1 on the knife rest of lathe, can fix link 1 through bolt and connecting hole 3 on the knife rest, can fix connecting block 2 on link 1 through locking bolt 7 and bolt hole 8, then fix center drill clamp 5 in the outside of arch 4, and drilling rod 6 is fixed at the tip of center drill clamp 5, realized fixing drilling rod 6, the installation step and the cost of vice knife rest have been saved to traditional cutter, the process is simplified, this cutter is applicable in the drilling operation of difference simultaneously, it is more convenient to use.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
