Background technology
Hole boring knife is for be applied to make the product of larger aperture mostly; Habitual boring tool utilizes a body (or claiming hilt) the affixed blade of front end; Again by turning the related cutting path that impels blade to produce rotation of body at a high speed, in view of the above to reach blade causes cutting to the work object purpose.Common Hole boring knife comprises a tool rest body at present; In the tool rest body, be equiped with a sliding seat; End at this sliding seat is used for installing blade bearing again, and the other end then reaches linearly moving purpose by the rotation of an adjustment bolt, if will finely tune this sliding seat; Then must cooperate with the accurate external screw thread of this adjustment bolt, reach the purpose of fine setting by the accurate internal thread of this sliding seat.
Yet, in the process of cutting, use cutting fluid through regular meeting and reach cooling purpose; The end that cutting fluid is then combined with blade bearing by this sliding seat easily gets into; And then this adjustment bolt is got rusty and corrode, to use down permanent, the inner screw thread meeting with the adjustment bolt of this sliding seat lose its effect because of corrosion; Make the adjustment bolt can't finely tune this sliding seat, and cause processing to produce error.
Summary of the invention
For improving above-mentioned problem, the purpose of the utility model is, a kind of waterproof construction of Hole boring knife is provided, and it can be avoided aqueous vapor to be got in the sliding seat by blade bearing and cause inside to be got rusty and corrode, and reaches the adjustment precision of keeping the adjustment bolt, and saves cost.
For realizing above-mentioned purpose; The utility model provides a kind of waterproof construction of Hole boring knife; Include a tool rest body, this tool rest body is provided with an axis hole, is provided with a sliding seat in this axis hole; The one of which end of this sliding seat is an assembling end of installing blade bearing; And but the in addition end of this sliding seat then is provided with one first internal thread segment spiral shell and establishes an adjustment bolt, and this adjustment bolt is limited in this sliding seat to this axis hole through a dividing plate spiral shell is solid again, and it is mobile to drive this sliding seat linearity when making this adjustment bolt rotation; It is characterized in that: one second internal thread segment that is provided with a screw lock blade bearing in this assembling end; Between this second internal thread segment and this first internal thread segment, be provided with a waterproof gasket, make the corrosion of this adjustment bolt in this first internal thread segment and damage to prevent that water gas from entering to by blade bearing.
Wherein, this waterproof gasket is an ethene dragon pad.
Wherein, this first internal thread segment is located in the copper sheathing and is cooperated with this adjustment bolt, and this copper sheathing is fixed in this sliding seat again.
Wherein, the free end of this adjustment bolt is extended with a baffle ring and a protuberance, and this dividing plate is provided with to bore a hole and supplies this protuberance to pass through again.
Wherein, this protuberance is outer must a sheathed dial.
The utility model beneficial effect: the waterproof construction of the Hole boring knife of the utility model is in the process of using; Can avoid liquid such as cutting fluid to get in this sliding seat inside and cause this second thread segment, this adjustment bolt to produce the problem generation of corrosion by this assembling end that is installed in blade bearing; Not only can keep the adjustment precision of this adjustment bolt, and can avoid eliminating the situation generation of changing total because of the part corrosion must spend mint of money.

Fig. 3: the generalized section of the utility model.
The specific embodiment
Consult Fig. 1 to shown in Figure 3, the utility model provides a kind of waterproof construction of Hole boring knife, includes a tool rest body 1; This tool rest body 1 is provided with an axis hole 10; Be provided with a sliding seat 2 in this axis hole 10, the one of which end of this sliding seat 2 is an assembling end 21 of installing blade bearing 7, but and the end in addition of this sliding seat 2 then be provided with one first internal thread segment, 23 spiral shells and establish an adjustment bolt 30; Wherein this first internal thread segment 23 can be located in the copper sheathing 8 and cooperate with this adjustment bolt 30; This copper sheathing 8 is fixed in and is another embodiment of the utility model in this sliding seat 2 again, and wherein, the free end of this adjustment bolt 30 is extended with a baffle ring 301 and a protuberance 303; This adjustment bolt 30 is limited in this sliding seat 2 to this axis hole 10 through a dividing plate 40 spiral shells are solid again; And this dividing plate 40 is provided with this protuberance 303 of confession of boring a hole to be passed through, and can drive this sliding seat 2 linear moving when this adjustment bolt 30 is rotated, and gets a sheathed dial 50 outside this protuberance 303 again;
It is characterized in that: one second internal thread segment 211 that is provided with screw lock blade bearing 7 in this assembling end 21; Be provided with a waterproof gasket 6 in this second internal thread segment 211 and 23 of this first internal thread segment; Make maybe this adjustment bolt 30 corrosion and damaging of these sliding seat 2 inside in this first internal thread segment 23 to prevent that water gas from entering to by blade bearing 7; Wherein, this waterproof gasket 6 is an ethene dragon pad.Again, another embodiment of the utility model is located at 8 last times of this copper sheathing for this first internal thread segment 23, and then 6 of this waterproof gaskets are located in this copper sheathing 8 and this second internal thread segment 211 and should be belonged in the category of the utility model protection.
By this; Because of this first internal thread segment 23 is provided with this waterproof gasket 6 with this second internal thread segment 211; So the utility model is in the process of using; Can avoid liquid such as cutting fluid to get in these first internal thread segment 23, and then get in this this second internal thread segment 211, use this second thread segment 211, these adjustment bolts 30 generation corrosions of preventing that this sliding seat 2 is inner by this assembling end 21 that is installed in blade bearing 7; Not only can keep the adjustment precision of this adjustment bolt 30, and can avoid eliminating the situation generation of changing total because of the part corrosion must spend mint of money.
