Description

[Detailed Description of the Invention] The present invention relates to a small-sized shot blasting device that can easily clean various small parts.

Conventional shot blasting equipment is a large machine that processes large lots, and is therefore completely unsuitable for cleaning a small number of small parts.

This invention has been miniaturized so that it can efficiently clean various small parts one by one, which are especially needed these days.
In other words, shot blasting is performed by rotating an impeller and a workpiece attachment/detachment mechanism inside the main body, which has an appropriate internal volume, and workpieces can be attached/detached using a pedal provided outside the main body. One embodiment will be described with reference to the drawings.

In the drawing, 1 is a motor, and the motor mounting bolt is 30
It is fixed to the turret frame 29 by.

Reference numerals 2 and 3 denote an impeller drive pulley and a workpiece drive pulley, respectively, which are keyed to the rotating shaft of the motor 1.

Reference numerals 4 and 5 are endless belts, which are stretched between the impeller driving pulley 2 and the impeller rotating pulley 9 and between the workpiece driving pulley 3 and the workpiece driven pulley 7, respectively.

Reference numeral 6 denotes an andra for adjusting the tension of the V-belt 5, and reference numeral 8 denotes a bearing that rotatably supports the shaft of the workpiece driven pulley 7 and the shaft of the workpiece support disk 12 provided inside the main body 25. The box 10 is a bearing rotatably supporting the shaft of the impeller rotating pulley 9 and the shaft of the impeller 28 provided inside the main body 25, and 11 is an opening/closing lid provided on the top of the main body 25. .

Reference numeral 13 designates a workpiece fixing fitting provided in the main body 25 facing the workpiece support disk 12, 14 a shaft connecting member, and 15 a rubber packing.

16 is a bracket in which a workpiece fixing shaft 17, a bearing 18, a thrust bearing 19, a compression spring 20, and a wire fixing member 21 are provided.

A wire rope 23 has one end tied to the wire fixing member 21 via a pulley 22 and the other end tied to a pedal 24 provided outside the main body 25.

26 is a liner provided at and near the bottom of the main body 25, 27 is a shot, and 31 is a dust collection duct.

The workpiece fixing fitting 13 can be easily removed from the shaft connecting member 14 and can be replaced depending on the shape of the workpiece, that is, the shape of the part to be cleaned.

In the work rotation type small shot blasting device constructed in this way, when the lid 11 is opened and the pedal 24 is depressed, the wire rope 23 is pulled downward and the direction is changed by 90 degrees via the pulley 22. The spring 20 is compressed and the workpiece fixing shaft 17 is moved to the left in FIG.

At this time, a gap is created between the workpiece fixing fitting 13 and the workpiece support disk 12.

Therefore, if you put a workpiece to be cleaned here and take your foot off the pedal 24, the workpiece fixing shaft 17 will move to the right in FIG. being pushed towards you.

At this time, the workpiece is supported parallel to the rotation axis of the impeller, and the workpiece is sandwiched between the workpiece fixing fitting 13 and the workpiece support disk 12. 12, a play is provided in order to eliminate uneven cleaning.

That is, several shallow holes are formed in the support disk 12 in order to ensure torque transmission to the workpiece fixing fitting 13.

Once the installation of the workpiece is completed in this way, the lid 1
1 and press a start button (not shown), the motor 1 will start rotating.

Along with the rotation of this motor, the impeller 28 rotates via the impeller drive pulley 2, ■belt 4, and impeller rotation pulley 9, which are power transmission devices, and similarly, the workpiece drive pulley 3, ■belt 5, and the workpiece side driven The workpiece rotates via the pulley 7 and the workpiece support disk 12.

Then, the impeller 28 launches the shot 27 stored at the bottom of the main body 25 and causes the shot 27 to collide with the workpiece, thereby cleaning the workpiece.

When this cleaning is completed and the motor 1 is stopped, the lid 11 is opened and the pedal 24 is depressed to open a gap between the workpiece fixing fitting 13 and the workpiece support disk 12, and the workpiece is taken out from the inside of the main body.

Therefore, since the work rotation type small-sized shot blasting device of the present invention is equipped with an impeller rotatably provided inside the main body, a work support plate, and a work fixing device, there is a gap between the work supporting plate and the work fixing device. Supports small parts one by one for efficient cleaning.
Moreover, since the small parts also rotate, the cleaning can be completed in a short time and the cleaning can be done evenly.

Furthermore, since a pedal is provided on the outside of the main body to move the workpiece fixing tool toward and away from the workpiece support plate, the workpiece, that is, small parts, can be attached and detached by operating the pedal from the outside. This provides various effects such as extremely easy attachment and detachment of the small parts.
