Description
Technical field
The utility model relates to the processing of big electric motor end cap bearing chamber, the processing of specifically a kind of electric motor end cap bearing hole is filled
It sets.
Background technique
In the part process of middle size motor (such as H400 motor), the bearing hole of electric motor end cap is having a size of φ 280H6
(+0.032), cylindricity requires 0.012mm, and dimensional tolerance and Geometrical Tolerance Principle are stringent, are 6 class precisions.Reach this essence
Degree, needs using specific purpose tool, i.e., squeezes knife using internal diameter to process, and the internal diameter of φ 280 squeezes knife, and market price is 1850 yuan,
Price is more expensive, and limitation is larger.Therefore, for this status, there is an urgent need to develop a kind of processing of electric motor end cap bearing hole dresses
It sets, to overcome the shortcomings of in currently practical application.
Utility model content
The purpose of this utility model is to provide a kind of processing unit (plant)s of electric motor end cap bearing hole, to solve above-mentioned background skill
The problem of being proposed in art.
To achieve the above object, the utility model provides the following technical solutions:
A kind of processing unit (plant) of electric motor end cap bearing hole, including knife handle, the knife handle pass through centering cylinder and the first bolt
It is mounted on the knife rest of vertical lathe, floating boring tool is installed, the lower end of the knife handle is also in the lower end square hole of the knife handle
Equipped with the second bolt for floating boring tool to be fixed.
As a further solution of the present invention: the floating boring tool can in square hole undamped it is mobile.
As a further solution of the present invention: the square hole is made of linear cutter.
As a further solution of the present invention: the floating boring tool includes fixed cutter body, carbide bit and work
Carbide bit is welded in moving knife body, fixed cutter body and movable cutter body, the end of fixed cutter body, which is equipped with, enables to movable blade
Body mobile micrometer adjusting screw of telescopic adjustment in fixed cutter body slot.
As a further solution of the present invention: the floating boring tool further includes for fixed cutter body and movable cutter body
Between the holding screw that locks.
Compared with prior art, the utility model has the beneficial effects that the processing unit (plant) of the electric motor end cap bearing hole, uses
Hard alloy adjustable floating boring cutter cuts simultaneous wide cutting edge extrusion molding, and the hole surface after boring is closely smooth, finish, cylinder
Degree, boring machining allowance are all well controlled, and ensure that the dimensional accuracy of floating boring tool processing metapore and geometric tolerance are wanted
It asks.
Detailed description of the invention
Fig. 1 is the axonometric schematic diagram of the utility model.
Fig. 2 is the floating boring tool schematic diagram in the utility model.
In figure: 1- centering cylinder, the first bolt of 2-, 3- knife handle, 4- square hole, the second bolt of 5-, 11- micrometer adjusting screw, 12-
Fixed cutter body, 13- fastening screw, 14- carbide bit, 15- movable cutter body.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 1~2, in the utility model embodiment, a kind of processing unit (plant) of electric motor end cap bearing hole, including knife handle
3, the knife handle 3 is mounted on the knife rest of vertical lathe by centering cylinder 1 and the first bolt 2, and the installation for realizing knife handle 3 is fixed
, floating boring tool is installed in the lower end square hole 4 of the knife handle 3, it is desirable that floating boring tool with realizing undamped in square hole 4
It is mobile, thus the accuracy of manufacture of square hole 4 be it is very crucial, the square hole 4 is made of linear cutter, and to be guaranteed
To neutrality, because the production precision of square hole 4 directly affects the dimensional accuracy of bearing chamber, the hole otherwise processed and floating
Size when boring cutter is to knife has deviation, needs to carry out dimension conversion and dimension compensation, time-consuming in this way and inaccurate, when processing
It is recommended that cooled down and lubricated using diesel oil, to reduce the abrasion of floating boring tool, and with the finish for improving hole machined, due to boring
Knife is in floating state in square hole 4, therefore more demanding to the cylindricity and concentricity of bottom outlet, this can be by increasing together
Semifinishing process realizes that the finish of the metapore of semifinishing, cylindricity, boring machining allowance all controlled well
System, ensure that floating boring tool processing metapore dimensional accuracy and Geometrical Tolerance Principle, the lower end of the knife handle 3 be additionally provided with for pair
The second bolt 5 that floating boring tool is fixed.
In the present embodiment, the floating boring tool includes fixed cutter body 12, carbide bit 14 and movable cutter body 15, is fixed
Carbide bit 14 is welded on cutter hub 12 and movable cutter body 15, the end of fixed cutter body 12, which is equipped with, enables to movable cutter body 15
The mobile micrometer adjusting screw 11 of telescopic adjustment in 12 slot of fixed cutter body, floating boring tool further includes for fixed cutter body 12 and activity
The holding screw 13 locked between cutter hub 15, carries out the adjustment of size, after controlling size with micrometer, tightens holding screw
13, so that it may use.
The processing unit (plant) of the electric motor end cap bearing hole cuts using hard alloy adjustable floating boring cutter and wide cutting edge squeezes
Pressing formation, the hole surface after boring is closely smooth, and finish, cylindricity, boring machining allowance are all well controlled, and ensure that
The dimensional accuracy and Geometrical Tolerance Principle of floating boring tool processing metapore.
The above are merely preferred embodiments of the present invention, it is noted that for those skilled in the art,
Without departing from the concept of the premise utility, several modifications and improvements can also be made, these also should be considered as practical
Novel protection scope, these all will not influence the effect and patent practicability of the utility model implementation.
