Abstract
The utility model discloses a device for machining bores of thin-wall bushes, which relates to an improvement of the device for machining bores of thin-wall bushes. The device has the advantages of convenient use, stable quality and high efficiency. The device comprises an outer sleeve, the structure of the device is characterized in that an inner sleeve is arranged in the outer sleeve, an oil chamber is arranged between the inner sleeve and the outer sleeve, and the periphery of the outer sleeve is provided with a stop valve which can be connected with a quick coupling of a hydraulic pump.
Description
Technical field:
The utility model relates to the improvement of hole processing device in the thin-wall bush.
Background technology:
Thin-wall bush is thinner owing to wall, and the axiality of cylindricity, external diameter and internal diameter is all had higher requirement, and being installed with conventional method is easy to distortion, is difficult to guarantee product quality.For example we are being certain steel mill's machining spindle watt-hour, and material is steel and karmarsch alloy composite, and wall is relatively thinner only to be 3.8mm, and cylindrical and endoporus axiality are 0.01mm, and the endoporus cylindricity is 0.008mm.Beginning us is installed with traditional form of being installed, (this moment, inside and outside circle all had allowance with chuck card cylindrical roughing endoporus during roughing, can not produce the distortion that is installed so workpiece wall is thicker), go up mandrel fine finishining cylindrical then, last right boring endoporus, take to use pressing plate during the right boring endoporus, press the method chucking of cylindrical or end face.Because the bearing shell wall after the fine finishining is thinner, the distortion that makes bearing shell that is installed in this way can not get control, and product processed does not reach designing requirement.
Summary of the invention:
The utility model is exactly at the problems referred to above, and the device of a kind of easy to use, steady quality, processing thin-walled lining endoporus that efficient is high is provided.
For realizing above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, and the utility model comprises overcoat, is provided with interior cover in its structural feature overcoat, be provided with oil pocket between interior cover and the overcoat, the overcoat cylindrical is provided with the stop valve that can link to each other with the snap joint of hydraulic pump.
The beneficial effects of the utility model:
1, product quality improves:
Because thin-wall bush is evenly stressed when being installed, and has solved the problem on deformation that is installed, and the quality of product is improved;
2, easy to use, efficient is high:
Since of the present utility model simple in structure, on lathe, be installed conveniently, behind the centering, can process typical products in mass production, easy to operate;
3, the lathe applicability is strong:
Can on engine lathe, grinding machine, boring and milling machine, use.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the user mode schematic diagram of the utility model at engine lathe, grinding machine;
Fig. 3 is the user mode schematic diagram of the utility model on boring and milling machine.
The specific embodiment:
The utility model comprises overcoat 4, and cover 6 is provided with oil pocket 5 between interior cover 6 and the overcoat 4 in being provided with in the overcoat 4, and overcoat 4 cylindricals are provided with the stop valve 3 that can link to each other with the snap joint 2 of hydraulic pump 1.
Be connected with interference fits between overcoat 4 and the interior cover 6.
Below in conjunction with a description of drawings course of action of the present utility model:
1, accompanying drawing 2 is the utility model usings method on engine lathe, grinding machine:
On lathe, grinding machine, use, the utility model device tightens and the endoporus centerings with chuck 7, and the thin-wall bush 8 that then external diameter is processed is put into the utility model device and suppressed, after waiting to tighten, close stop valve 3 (pressure meter switch) and disconnect snap joint 2, get final product the endoporus of processing thin-walled lining 8.
2, accompanying drawing 3 is usings method on boring and milling machine:
On boring and milling machine, with the utility model device centering chucking in supporting seat 9, the thin-wall bush 8 that then external diameter is processed is put into the utility model device and is suppressed, and the stop valve 3 of closing then on the hydraulic pump 1 can be processed endoporus.
