Abstract
The utility model discloses a barbed boring transition connecting rod device. The device comprises a boring cutter and a transition connecting rod connected with the boring cutter, wherein a cooling water outlet hole is formed in the transition connecting rod; and the bottom of the cooling water outlet hole is connected with an inclined water outlet which is led to the outside of the transition connecting rod. By using the barbed boring transition connecting rod device, a common steel boring tool can be clamped; the barbed boring transition connecting rod device can replace an advanced barbed boring tool abroad for barbed boring machining; moreover, the extended length of the common steel boring tool can be adjusted according to the difference between the diameters of a large hole and a small hole of a component; the barbed boring machining of component holes with different diameter differences is realized; the procurement cost of the tool is reduced; and the device is convenient to use.
Description
Technical field
The utility model relates to a kind of deep hole boring device, the transition of barb boring specifically extension bar device.
Background technology
In machining, have stepped hole on some part, and when the establishment parts machining process, the processing method that must pass the barb boring of processing small holes macropore realizes.Conventional processing method is to adopt external advanced barb borer to carry out the barb boring processing; Basically can satisfy the requirement of part machining, but macropore and hole diameter difference be when excessive, standard barb borer can not satisfy its processing; Must order nonstandard barb borer; And nonstandard barb borer price comparison is expensive, and the order cycle time is also long, and is not high for its processing feasibility of parts in small batch.
Summary of the invention
The purpose of the utility model is the deficiency that exists to prior art; A kind of barb boring transition extension bar device is provided, but the common steel borer of this device clamping, and not only advanced barb borer carries out the barb boring processing outside the subrogate country; And can regulate common steel borer extension elongation according to part macropore and hole diameter difference; Realize the barb boring processing of different-diameter difference hole in piece part, reduce the cutter purchase cost, easy to use.
For realizing above-mentioned utility model purpose, the technical scheme that the utility model adopts is a kind of barb boring transition extension bar device, the transition extension bar that comprises boring cutter and join with it; Said transition extension bar inside is provided with the cooling water apopore, is connected in cooling water apopore bottom and leads to the outside oblique apopore of transition extension bar.
Said boring cutter is connected through screw with the transition extension bar.
Beneficial effect: the utlity model has following advantage:
1, with barb borer and nonstandard barb borer advanced outside the common steel borer subrogate country, realize the barb boring processing, reduce cost; 2, can realize the inner water outlet of transition extension bar to cutter cool off 3, installing hole on the transition extension bar can be according to the handle designs of common steel borer; 4, when many kinds, small batch part processing, but the common steel borer of this device clamping is realized the barb boring processing, reduces the cutter purchase cost, and is easy to use.
Description of drawings
Fig. 1 is the utility model structural representation, and 6 is connecting hole among the figure.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, further illustrate the utility model, present embodiment is being to implement under the prerequisite with the utility model technical scheme, should understand these embodiment only be used to the utility model is described and be not used in the restriction the utility model scope.
As shown in Figure 1, a kind of barb boring transition extension bar device, the transition extension bar 2 that comprises boring cutter 1 and join with it; Transition extension bar 2 inside are provided with cooling water apopore 3, are connected to the oblique apopore 4 that leads to transition extension bar 2 outsides in cooling water apopore 3 bottoms, and boring cutter 1 is connected with connecting hole 6 through screw 5 with transition extension bar 2.
Operation principle: earlier transition extension bar 2 is fixed in the endoporus boring cutter seat on the cutterhead annex, through screw 5 common steel boring cutter 1 is fixed in the installing hole 6 on the transition extension bar 2 again, and adjusts common steel boring cutter 1 nose center high position.Add man-hour, the lathe coolant pump starts, and cooling fluid imports through the endoporus boring cutter seat on the cutterhead in the cooling water apopore 3 of transition extension bar 2, from oblique apopore 4 ejections of transition extension bar 2, realizes cooling off point of a knife in the part processing process again.
Claims (2)
1. a barb boring transition extension bar device is characterized in that: the transition extension bar (2) that comprises boring cutter (1) and join with it; Said transition extension bar (2) inside is provided with cooling water apopore (3), is connected in cooling water apopore (3) bottom and leads to the outside oblique apopore (4) of transition extension bar (2).
