Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a mechanism for periodically polishing components, in particular, a micro component polishing mechanism.

[Conventional technology]

2. Description of the Related Art Conventionally, when polishing a small component, the component may be directly polished using a hand file. Also, as shown in FIG. 3, an external polishing jig composed of a polishing file 1, a file driving motor 12, a component mounting holder 13, and a component mounting holder up spring 14 is used to mount the component P removed from the apparatus. It is general that the part P is set on the holder 13, the part mounting holder 13 is pressed down by hand, and the part P and the polishing file 1 are brought into contact with each other and polished.

[Problems to be solved by the invention]

In the conventional polishing method described above, when a hand file is used, the parallel accuracy of the polished surface is not sufficiently obtained, and depending on the mounting position of the component, the hand file does not sufficiently hit the component surface, resulting in insufficient polishing. is there.

Also, by using an external polishing jig, the parallelism of the removed parts can be secured, but there are disadvantages such as an increase in the number of steps for attaching and detaching the parts and non-uniform mounting accuracy of the parts at the time of detaching.
If these measures are taken in terms of a device, there is a disadvantage that the cost is increased and the maintainability is lacking.

An object of the present invention is to provide a polishing mechanism for a part which solves the above problems.

[Differences of the invention from the prior art]

In contrast to the above-mentioned conventional method of polishing a part using a hand file or an external polishing jig, the present invention reduces the size of the polishing machine, and also provides the polishing file with pressurizing properties to the part, and assembles or removes the part in the apparatus. However, there is a difference that polishing can be performed.

[Means for solving the problem]

In order to achieve the above object, a component polishing mechanism according to the present invention has a machine frame, a drive unit, and a polishing file, and is a component polishing mechanism for polishing a component by a polishing file. Is removably incorporated in a device provided with a component to be polished, and the driving unit is formed by a set of two spur gears engaged with each other,
The driven-side spur gear slides in a tooth thickness mesh in the thickness direction via a polishing pressure spring, and the polishing file is mounted on an end face of the driven-side spur gear. The drive unit, the polishing file, and the pressing spring for polishing are integrated into the machine frame to form a unitized structure.

〔Example〕

 Next, the present invention will be described with reference to the drawings.

(Embodiment 1) FIG. 1 is a perspective view showing Embodiment 1 of the present invention.

In the figure, a polishing mechanism according to the present invention includes a small motor 2 serving as a driving source for rotation, a gear head 3 for adjusting rotation torque, spur gears 4 and 5 for transmitting rotation, and a part P for polishing. A polishing pressurizing spring 7 for applying pressure and a polishing file 1 are integrally incorporated into a machine frame M which is removably incorporated in an apparatus having a part P to be polished, and has a unitized structure. It is constituted as. The polishing file 1 is mounted on a spur gear 5. The spur gear 5 is supported by a rotating shaft 6 so as to be able to move up and down in the vertical direction, and is urged upward by a polishing pressure spring 7.

The rotation of the small motor 2 is controlled by the spur gear 4 via the gear head 3.
And the spur gear 5 further rotates. The polishing file 1 is fixed on the spur gear 5, and the rotation of the small motor 2 causes the polishing file 1 to rotate. In the polishing mechanism according to the present invention, when the machine frame M is mounted on a device to which a component P to be polished is attached, the polishing file 1 is set under the component P, and the polishing file 1 is brought into contact with the component P. The spur gear 5 slides down on the rotating shaft 6 to compress the polishing pressurizing spring 7, and the reaction force thereof is pressed against the part P, so that polishing is possible.

The pressing force of the polishing file 1 against the part P is generated by the polishing pressurizing spring 7, and the deflection of the polishing pressurizing spring 7 is absorbed by the deviation in the thickness of the spur gears 4 and 5, so that it can be incorporated into the device. It becomes possible.

Further, by using the small motor 2 as a DC motor and switching the polarity with a switch or the like, the polishing file 1 can also be rotated forward and reverse.

Second Embodiment FIG. 2 is a perspective view showing a second embodiment of the present invention.

In this embodiment, a plurality of polishing files are integrated into a machine frame M in which several parts are removably assembled in a device arranged in parallel, and a unitary structure is integrally formed. Since polishing can be performed, there is an advantage that time is shortened.

That is, the rotation of the small motor 2 is controlled by the gear head 3, the spur gear,
It is transmitted to the rotating shaft 8 via 4 and 5. A worm 9 is mounted on the rotating shaft 8 and a wheel 10 corresponding to the mounting position of the worm 9 is mounted to convert the rotation in the horizontal direction to the vertical direction. A rotating slider shaft 11 having a function of rotating and vertically sliding is provided at the center of the wheel 10, and the polishing file 1 is fixed to the rotating slider shaft 11, and the polishing spring 7 is inserted between the polishing file 1 and the wheel 10. By doing so, it becomes a multiple part polishing mechanism that can be incorporated into the apparatus. Also, depending on the size space, the spur gears 4 and 5 are eliminated and the small motor 2 and rotating shaft 8
Have the same function even if they are directly connected.

 The following table shows a comparison between the present invention and a conventional example.

[Effects of the Invention] According to the present invention described above, polishing can be performed without removing components from the apparatus, and there is a great effect in preventing trouble due to parallel accuracy after component polishing and in reducing the number of component polishing steps.
