Abstract
The utility model discloses a fine grinding tool of a single-point hinge inner hole, a main shaft penetrates the centers of two grinding tool fixed disks which are arranged at an interval to be fixed, and a pneumatic drill is arranged at one end of the main shaft; a stepped hole is formed on the outer diameter edge of each grinding tool fixed disk every 120 DEG central angle; a spring and a pin are sequentially arranged in the stepped hole; and as an oilstone strip with the lower part accommodated in the stepped hole is attached to the outer end of the pin, the two ends of the oilstone strip are correspondingly arranged in the stepped holes of the grinding tool fixed disks on the two sides. The novel hole grinding machine main shaft is connected with the ordinary air drill, so as to produce high-speed rotation. As the three oilstone strips float in machining holes, a high machining precision is ensured; and the fine grinding tool of the single-point hinge inner hole is more suitable for on-site grinding and machining, and has the advantages that the machining difficulty is reduced and the machining efficiency is improved.
Description
Technical field
The present invention relates to a kind of grinding tool, more particularly, relate to and be used for the accurately machined grinding tool of single-point hinge endoporus.
Background technology
In the manufacturing of single point mooring unit, run into the processing in various holes through regular meeting.Because the relation of structure, these holes process with assembly machine often at the scene.But because the roughness in some hole is had relatively high expectations, in the scope of the 0.8-1.6 that is everlasting, and assembly machine does not reach this required precision.
Summary of the invention
The present invention is intended to make the on-the-spot grinding out equipment of a cover, after the machined of single-point hinge assemblies is accomplished, utilizes hole grinding machine correct grinding single-point hinge endoporus of the present invention, reaches required required precision, thereby reduces difficulty of processing and cost, improves working (machining) efficiency.
In order to achieve the above object, a kind of single-point hinge of the present invention endoporus correct grinding instrument, the center fixation of passing two grinding tool fixed disks that are provided with at interval is provided with main shaft.One end of main shaft is provided with the air drill link; The per 120 degree central angles in the external diameter edge of each grinding tool fixed disk are offered a shoulder hole.Set gradually spring, bearing pin in the said shoulder hole from inside to outside.The bottom that reclines, the outer end of said bearing pin is contained in the rectangular oilstone in the said shoulder hole; This makes the two ends correspondence of said rectangular oilstone be arranged in the shoulder hole of said grinding tool fixed disk of both sides, and three said oilstones uniformly-spaced are set on the circumference of each said grinding tool fixed disk.
In addition, under the optimal way, the outside card of said grinding tool fixed disk is upper in the distolateral position-limit mechanism that is provided with of said oilstone, owing to limit the lengthwise position of oilstone.
Hole grinding machine main shaft of the present invention links to each other with common air drill, produces rotation at a high speed.Three bar shaped oilstones are in quick condition in processed hole, thereby can guarantee the machining accuracy that reaches very high, and to the not very high requirement of installation of whole hole grinding machine, therefore are more suitable for accomplishing under the condition at the scene the grinding in hole.Grinding tool of the present invention can guarantee the grinding accuracy requirement of single-point hinge endoporus, reduces difficulty of processing and cost simultaneously, improves working (machining) efficiency.

The specific embodiment
A kind of single-point hinge endoporus correct grinding instrument shown in Fig. 1-4, the center fixation of passing two grinding tool fixed disks 5 that are provided with at interval is provided with main shaft 1, and an end of main shaft 1 is provided with the air drill link; The per 120 degree central angles in the external diameter edge of each grinding tool fixed disk 5 are offered a shoulder hole, set gradually spring 3, bearing pin 2 in the shoulder hole from inside to outside.The bottom that reclines, the outer end of bearing pin 2 is contained in the rectangular oilstone 4 in the said shoulder hole, and this makes the two ends correspondence of rectangular oilstone 4 be arranged in the shoulder hole of said grinding tool fixed disk 5 of both sides.The outside card of grinding tool fixed disk 5 is upper in the distolateral position-limit mechanism that is provided with of said oilstone 4.
As shown in Figure 5, correct grinding instrument of the present invention produces rotation at a high speed through the rotation output of the air drill link 7 connection air drills of main shaft 1 rear end.In order to increase the support stiffness of main shaft 1, the outside at main shaft 1 middle part adds spring bearing 6 among Fig. 5.Three bar shaped oilstones are placed in the processed hole 8, and this moment, oilstone was in quick condition, thereby can guarantee the machining accuracy that reaches very high, and to the not very high requirement of installation of whole hole grinding machine, so was more suitable for the grinding in completion hole under the condition at the scene.
The above; Be merely the preferable specific embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any technical staff who is familiar with the present technique field is equal to replacement or change according to technical scheme of the present invention and inventive concept thereof in the technical scope that the present invention discloses, all should be encompassed within protection scope of the present invention.
