Abstract
Disclosed by the utility model is a kind of same axis machining apparatus of expansion sleeve type of clamp art, including coaxial gripping section, positioning section and expansion set section, the outer circle of the positioning section is greater than gripping section and expansion set section, the expansion set section is thin walled cylinder body structure, and equipped at least three openings on the length direction of expansion set section, the opening is axisymmetricly arranged.The beneficial effects of the utility model are: realizing the transmitting of machine finish using expansion sleeve type structure, and then guarantee the degree of precision control of part working axiality, in the case where not considering process tool abrasion, the coaxiality deviation range of finished part is substantially reduced.
Description
Technical field
The utility model relates to clamp art more particularly to a kind of same axis machining apparatus of expansion sleeve type.
Background technique
When producing thin-wall sleeve parts in batches, it is contemplated that production cost is generally used the progress of non NC machining lathe
Processing, but the positioning accuracy of machine tool is not high, in the more demanding thin-wall sleeve class part volume of working axiality, concentricity
Control difficulty it is relatively large.All be using more fixture at present it is clipping, positioning accuracy is not easy to control, and there are also broken
The risk of bad surface quality of workpieces.
Utility model content
To overcome existing clipping fixture poor to the concentricity control of thin-wall sleeve parts, it is easily destroyed piece surface matter
The deficiencies of amount, the technical problem to be solved by the utility model is to provide one kind more can guarantee that the expansion sleeve type of concentricity coaxially adds
Tooling is set.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
The same axis machining apparatus of expansion sleeve type, including coaxial gripping section, positioning section and expansion set section, the outer circle of the positioning section is big
In gripping section and expansion set section, the expansion set section is thin walled cylinder body structure, and at least three are equipped on the length direction of expansion set section
Road opening, the opening are axisymmetricly arranged.
Further, the walled thickness of the expansion set section is 3~5mm.
Further, the expansion set section is equipped with three openings.
Further, the width of the opening is 3~5mm.
Further, being equipped with chamfering, chamfer angle and tailstock tool on the inside of one end of remotely located section of the expansion set section
Thimble angle is consistent.
The beneficial effects of the utility model are: realizing the transmitting of machine finish, Jin Erbao using expansion sleeve type structure
The degree of precision control for demonstrate,proving part working axiality, in the case where not considering process tool abrasion, the concentricity of finished part
Deviation range is substantially reduced.
Detailed description of the invention
Fig. 1 is the utility model structural front view.
Fig. 2 is the utility model expansion set section cross-sectional view.
Label is 1- gripping section, 2- positioning section, 3- expansion set section, 4- opening in figure.
Specific embodiment
The present invention will be further described with reference to the accompanying drawing.
As shown in Figure 1 and Figure 2, the same axis machining apparatus of the expansion sleeve type of the utility model, including coaxial gripping section 1, positioning section
2 and expansion set section 3, the outer circle of the positioning section 2 is greater than gripping section 1 and expansion set section 3, and the expansion set section 3 is thin walled cylinder body structure, and
And at least three openings 4 are equipped on the length direction of expansion set section 3, the multiple tracks opening 4 is axisymmetricly arranged.The gripping section
1, positioning section 2 and expansion set section 3 are preferably an integral molding structure, and guarantee the concentricity of three sections of outer circles, material used by expansion set section 3
Answer elasticity with higher.
The use process of the utility model is: the insertion machine tool jaw of gripping section 1 being fixed first, gripping section 1 is adding
Working hour is smart benchmark, and entire processing unit (plant) and machine tool chief axis can be made coaxial, then the thin-wall sleeve parts processed will be needed to cover
In expansion set section 3, and axially position is realized using the end face of positioning section 2, the outer circle of the expansion set section 3 and the outer circle of gripping section 1 are same
Axis realizes the transmitting of machining benchmark, then the thimble of tailstock tool is recycled to withstand on the end of expansion set section 3, makes the thin of expansion set section 3
Wall have outside slight deformation it is swollen with processing inner bore of part fit closely, to realize the fixation of part and the biography again of machining benchmark
It passs, finally, by the ensuring coaxiality of knife rest and machine tool chief axis, and then realizing lathe using the tool sharpening part on knife rest
Machining accuracy is in expansion sleeve type with time transmitting in axis machining apparatus.
For structural stability and elasticity including expansion set section 3, the walled thickness of the expansion set section 3 is preferably 3~5mm.
Closely into order to reduce production process, three openings 4 are arranged in the expansion set section 3 can meet requirement.?
It is directly cut with blade when setting opening 4, therefore the width of opening 4 is controlled in 3~5mm.
Chamfering, chamfer angle and tailstock tool thimble angle one are equipped on the inside of one end that 3 remotely located sections 2 of the expansion set section
It causes.The purpose that chamfering is arranged is contact area in order to improve tailstock tool thimble Yu expansion set section, thus play uniformly strut it is swollen
Cover the purpose of section thin-walled.
The utility model realizes the transmitting of machine finish using expansion sleeve type structure, and then guarantees that part processing is coaxial
The degree of precision of degree controls, and in the case where not considering process tool abrasion, the coaxiality deviation range of finished part contracts significantly
It is small, there is good practicability and application prospect.
