Description

[Detailed description of the invention] (Industrial application field) The present invention is mainly used in the bearing manufacturing process to automatically wipe off processing aid liquid adhering to the surface of cylindrical processed products such as outer races and inner races. The present invention relates to a wiping device.

(Prior technology) Conventionally, in the field of bearing manufacturing, in order to remove dirt from the cutting and grinding processes that adheres to the surface of short cylindrical processed products such as outer races and inner races, cleaning liquid is used during the processing process. A cleaning process is incorporated to prevent adverse effects on processing dimensional accuracy and measurement/inspection accuracy in subsequent processes. Therefore, in the cleaning process, the cylindrical processed products such as the outer lace and inner lace may have machining aid liquids such as cutting oil or grinding fluid used in the previous process attached to their surfaces and brought into the cleaning process, or may be brought into the cleaning process. When the material is sent to the next process, a small amount of cleaning liquid is deposited on its surface and taken out.

(Problem to be solved by the invention) However, when a cleaning process using a cleaning liquid is incorporated into the manufacturing process of a cylindrical processed product using a processing aid liquid as described above, the product may be contaminated with water from the previous process. There is a problem that the processing aid liquid that enters interferes with the cleaning action and causes early deterioration due to deterioration of the quality of the cleaning liquid.In addition, the cleaning liquid that adheres to the cylindrical processed product and is taken out may cause processing defects in the subsequent process. It may also cause assembly defects.

In addition, the cleaning equipment used in the above-mentioned cleaning process generally removes dirt while circulating the cleaning liquid between the cleaning part, the cleaning liquid processing part, and the processing liquid delivery part, but depending on the arrangement of the cleaning process, In some cases, it is necessary to install an oil removal device, which has the disadvantage of raising the product price due to equipment costs and work space.

The present invention was developed by focusing on various problems in the conventional manufacturing process of cylindrical processed products such as outer laces and inner laces. The purpose is to prevent restrictions on locations and adverse effects on other processes, thereby solving the above-mentioned problems.

(Means for Solving the Problems) The structure of the present invention for achieving the above object will be explained with reference to the accompanying drawings FIGS. 1 and 2.

The automatic wiping device of the present invention is equipped with at least two placing rollers 2 and 3 for placing a cylindrical processed product W such as an outer race and an inner race of a bearing, and applying a rotational force to the product. The applying means 5 and the cylindrical processed product W are placed on the mounting rollers 2 and 3.
a wiping sheet supplying means 15 that supplies a wiping sheet S made of paper or nonwoven fabric, and a wiping sheet S supplied from the wiping sheet supplying means 15 to the rotating cylinder. A pressing means 10 for pressing the surface of the shaped processed product W is provided.

Further, the pressing means 10 and the pressing means 6 are
When the cylindrical processed product W is carried into a processing position on the rotational force applying means 5 or carried out from the position, it is retracted to a position where its movement is not hindered.

Further, the pressure means 10 is provided with a buffer made of foamed rubber or the like at a portion of a pressure frame 13 provided for pressing the wiping sheet S against the surface of the cylindrical processed product W, which faces the cylindrical processed product W. Material 1
4, and care has been taken not to damage the product surface.

(Function) The automatic wiping device of the present invention having the above-mentioned configuration is used by being incorporated into a conveyance path during the processing process or immediately before the product assembly process.
0 and the pressing means 6 are retracted as shown in FIG. 2, the cylindrical processed product W is placed on the placing rollers 2 and 3 of the rotational force applying means 5, and then pressed by the pressing means 6 as shown in FIG. The cylindrical processed product W is placed on the mounting roller 2,
3 while rotating the placing rollers 2 and 3,
The cylindrical processed product W is rotated on the mounting rollers 2 and 3. In this state, when the pressure means 10 is moved to press the wiping sheet S against the surface of the cylindrical processed product W, the wiping sheet S slides relative to the cylindrical processed product W. The processing aid liquid from the previous process adhering to the surface of the W is absorbed together with dirt to clean the surface of the cylindrical processed product W. Thus, the cylindrical processed product W whose surface has been purified is pressed by the pressurizing means 10.
By retracting the pressing means 6, the material becomes free to move and is transported to the next process. Note that the cleaning sheet S is supplied to the cleaning sheet supplying means 1 while waiting for work.
New parts are rolled out sequentially from 5 onwards.

The automatic wiping device of the present invention has the above-mentioned configuration, and its operation will be explained next. When performing wiping processing on a cylindrical processed product W that has been processed in the previous process, first, As shown in FIG.
Move it to a position where it will not interfere with the loading process, and close the loading frame 1.
One of the cylindrical processed products W arranged side by side above is placed on the placing rollers 2 and 3, and the piston rod 8 of the air cylinder 9 is extended as shown in Fig. 1, and the pressure roller 7 at the tip is used to process it into a cylindrical shape. When the outer peripheral surface of the product W is pressed and the cylindrical processed product W is strongly pressed against the mounting rollers 2 and 3, the drive motor 4 rotates the mounting rollers 2 and 3 in the same direction. rotates in a certain direction.

In this state, the machine frame to which the pressure means 10 and the cleaning sheet supply means 15 are attached is displaced in a direction approaching the cylindrical processed product W, and the piston rod 12 of the cylinder drive member 11 of the pressure means 10 is extended, The wiping sheet S is pressed by the pressure frame 13 via the cushioning material 14 against the outer surface of the cylindrical processed product W in a substantially normal direction.

At this time, the wiping sheet S is placed on the mounting rollers 2 and 3.
The unnecessary processing aid liquid adhering to the surface of the cylindrical processed product W due to relative sliding with the cylindrical processed product W which is rotationally driven in a certain direction by the cylindrical processed product W is absorbed, and the cylindrical processed product W is Wipe off any dirt adhering to the surface.

When the dust and processing aid liquid on the surface of the cylindrical processed product W have been sufficiently removed in this way, the piston rod 8 of the air cylinder 9 is contracted and the press roller 7 is processed into the cylindrical shape. At the same time as separating from the outer surface of the product W, the pressurizing means 10 is separated from the outer surface of the cylindrical processed product W, and the cylindrical processed product W is conveyed from the mounting rollers 2 and 3 through the carry-out frame 22 to the next process. good.

Further, the cleaning sheet S soiled by the above-mentioned cleaning process is usually removed from the feed roller 1 during retraction as shown in FIG.

Furthermore, in the above embodiment, the surface of the cylindrical processed product W is wiped once with the wiping sheet S. The portion is sent out about 3 to 5 cm and pressed against the cylindrical processed product W again and wiped twice. It is also possible to arrange the sets to be out of phase and perform the wiping process separately for rough wiping and finishing wiping.

Further, in the above embodiment, a case where the wiping process is performed only on the outer diameter surface of the cylindrical processed product W has been described, but for example, the wiping sheet supply means 15
A plurality of pressurizing means 10 are arranged for the outer diameter surface, inner diameter surface, and end surface of the cylindrical processed product W, and these are pressed together against the outer surface of the cylindrical processed product W to perform the wiping process. Alternatively, a wiping sheet S having a width wider than the width of the cylindrical processed product W may be used to wrap the cylindrical processed product W and perform the wiping process.

FIG. 3 shows another embodiment of the pressurizing means 10 that presses the wiping sheet S against the cylindrical processed product W, and is capable of coming into contact with and separating from the outer peripheral surface of the cylindrical processed product W. The pressurizing frame 13 is provided with two arms 23 and 24 at its tip so as to be able to swing open and close by expanding and contracting an air cylinder 26, with two arms 23 and 24 centered around fulcrum pins 25 and 25'. , cushioning materials 27, 27' that are pressed against the opposing surfaces of the ends of each arm 23, 24 so as to wrap the cylindrical processed product W in a C-shape with the wiping sheet S.

Therefore, in the automatic wiping device configured as described above, the pressure frame 13 approaches the cylindrical processed product W rotating on the mounting rollers 2 and 3 from the outer surface thereof, and the ends of the arms 23 and 24 clean the cylindrical processed product W. Since the wiping sheet S wraps around and presses the surface of the cylindrical processed product W, the mechanism is much simpler than when the pressure means 10 and the wiping sheet supply means 15 are provided exclusively for the outer diameter surface, inner diameter surface, and end surface. There is an advantage in being able to do so.

Although not disclosed in the drawings, since the cylindrical processed product W comes into direct contact with the placing rollers 2 and 3 and the pressing roller 7 and the processing aid liquid adheres thereto, a separate wiping mechanism is also provided for these. Although a wiping mechanism is attached, it is also possible to use one having the same structure as the embodiment shown in FIGS. 1 and 2 above.

(Effects of the invention) As described above, the automatic wiping device of the invention places cylindrical processed products such as outer races and inner races manufactured as bearing parts on the mounting roller during the processing process. A wiping sheet made of paper or non-woven fabric is pressed onto the surface of the product while rotating it in a fixed direction to remove dirt and unnecessary processing aid liquid from the surface before sending it to the next process. Because of this, the cleaning solution does not have a negative impact on the subsequent process unlike conventional cleaning solutions, and the cleaning sheet can be brought into contact with the surface of the product and peeled off from the finished surface to remove attached dirt. It is possible to easily remove hard-to-clean dirt, etc., and since there is no need for a cleaning liquid reprocessing device like in conventional cleaning equipment, the equipment can be made smaller and equipment costs can be reduced. It has the excellent effect of suppressing wide-ranging price increases.

Moreover, the automatic wiping device of the present invention can prevent the cleaning liquid from having an adverse effect on the subsequent process, and together with the miniaturization of the device, it can be placed at any position in the processing process. It is also expected to have the effect of significantly improving the processing accuracy, inspection accuracy, and assembly accuracy of cylindrical processed products such as bearings.
