Abstract
The invention discloses a sleeve for drill bit connection. The sleeve comprises a sleeve body, wherein the upper and lower parts of the sleeve body respectively refer to an inner connecting barrel (2) and an outer connecting barrel (1); the inner connecting barrel (2) and the outer connecting barrel (1) are connected integrally; the outer diameter of the inner connecting barrel (2) is equal to the inner diameter of the outer connecting barrel (1); external threads (3) are formed on the inner connecting barrel (2); and internal threads (4) matched with the external threads (3) are formed on the outer connecting barrel (1). According to the sleeve, a drill bit can be conveniently replaced, simultaneously the length of the sleeve can be adjusted and the operation is simple.
Description
Technical field
The present invention relates to a kind of sleeve, specifically a kind of sleeve for the drill bit connection.
Background technology
Along with the development of bore operation, drill bit is used more and morely as a kind of boring bar tool.Normally drill bit is fixedly connected with by modes such as welding with swing arm, so that drill bit has stronger stability.But the length of swing arm is fixing often, and we need a suitable length of rotary rod to cooperate with drill bit to carry out bore operation, so just caused some inconvenience sometimes.Also have, after drill bit or swing arm are damaged, can only be with drill bit and swing arm integral replacing, so not only practicality is not high, has also caused simultaneously the waste of resource.
Summary of the invention
Technical problem to be solved by this invention is a kind of sleeve for the drill bit connection that provide simple in structure, length is adjustable, is convenient for changing.
The present invention is that the technical solution problem is achieved through the following technical solutions: a kind of sleeve for the drill bit connection, comprise sleeve body, described sleeve body upper and lower part is respectively interior extend neck and outer extend neck, interior extend neck and outer extend neck are connected as a single entity, the external diameter of interior extend neck equates with the internal diameter of outer extend neck, interior extend neck is provided with external screw thread, and outer extend neck is provided with the internal thread that matches with external screw thread.Interior extend neck is used for fixed rotating shaft, connects drill bit in outer extend neck is used for, and can mutually link to each other with outer extend neck by interior extend neck between two sleeves, increases the length of sleeve.
The center line of described outer extend neck and interior extend neck overlaps.
The length of described outer extend neck is equal to or greater than the length of interior extend neck.
The present invention compared with prior art has the following advantages and beneficial effect:
(1) the present invention has substituted original swing arm, has adopted the combination of outer extend neck and interior extend neck, is connected to outer extend neck in the drill bit, can make the dismounting of drill bit very convenient.
(2) can interconnect between the present invention, so that whole sleeve is in adjustable state, can satisfy well the requirement of boring.
(3) the present invention is simple in structure, and is practical.
Description of drawings
Fig. 1 is front view of the present invention;
Fig. 2 is top view of the present invention;
Fig. 3 is sectional drawing of the present invention.
Corresponding Reference numeral is in the accompanying drawing: 1, outer extend neck, 2, interior extend neck, 3, external screw thread, 4, internal thread.
The specific embodiment
The present invention is described in further detail below in conjunction with embodiment, but embodiments of the present invention are not limited to this.
Embodiment:
Such as Fig. 1, Fig. 2 and shown in Figure 3, the present invention includes sleeve body, described sleeve body upper and lower part is respectively interior extend neck 2 and outer extend neck 1, interior extend neck 2 is used for fixed rotating shaft, connects drill bit in outer extend neck 1 is used for; Interior extend neck 2 is connected as a single entity with outer extend neck 1, and the external diameter of interior extend neck 2 equates that with the internal diameter of outer extend neck 1 outer extend neck 1 overlaps with the center line of interior extend neck 2; Interior extend neck 2 is provided with external screw thread 3, and outer extend neck 1 is provided with between 4, two sleeves of internal thread that match with external screw thread 3 and can mutually links to each other with outer extend neck by interior extend neck, increases the length of sleeve; The length of outer extend neck 1 is equal to or greater than the length of interior extend neck 2.
Operating principle of the present invention is: the present invention is socketed on the drill bit, is about to drill bit and screws in the outer extend neck 1, then, and can be according to the needs of length, sleeve superposeed one by one to connect together.After sleeve or drill bit are damaged, can easily the part of damage be taken off, thereby change new part.
As mentioned above, then can realize well the present invention.
