Description

Specification

Liquid houng processing machine and liquid houng processing method

Technical field

TECHNICAL FIELD [0001] The present invention relates to a liquid hounging force machine and a liquid hounging carriage method for liquid hounging various workpieces such as a precision pipe blank and a photosensitive drum base pipe blank.

Background art

For example, in a photosensitive drum mounted on an electronic copying machine, a laser printer, or the like, a photosensitive drum base that supports a photoconductive photosensitive layer such as selenium or an organic photosensitive member is aluminum (including an alloy thereof) or the like. It is formed from a metal pipe. This pipe is required to have high dimensional accuracy (eg, straightness) and high surface accuracy to obtain a high-quality image.

[0003] By the way, in many cases, this pipe is manufactured from a raw tube obtained by drawing, but such a raw tube often has a non-uniform surface state. Therefore, conventionally, in order to make the surface of the raw tube uniform (for example, uniformly roughened), the surface of the raw tube is subjected to a liquid honing treatment. Further, since foreign matter such as abrasive grains adheres to the surface of the raw tube subjected to the liquid houng treatment, the raw tube is washed to remove this foreign matter (for example, Patent Document 1 and 2).

As a result, the liquid can be ejected toward the workpiece at a position close to the workpiece just before being pulled up from the liquid in the transfer tank, and the removal rate of the foreign matter adhering to the workpiece is improved.

[0089] In the invention [9], the foreign matter floating on the liquid surface in the transport tank overflows with the liquid in the transport tank and is discharged out of the transport tank. Therefore, it is possible to prevent a decrease in the cleanliness of the liquid in the transfer tank, and it is possible to prevent foreign matters from reattaching to the work during the work transfer. Furthermore, foreign matter that has floated to the liquid surface in the transport tank overflows from the upper end of the side wall portion on the honing zone side, not the side wall portion on the cleaning zone side of the transport tank, and is discharged. There is no danger of being contaminated.

It is desirable that If it is less than 10 zm, it is difficult for foreign matter to enter the pores, and the cleaning liquid (120) becomes difficult to circulate. On the other hand, if it exceeds 500 x m, the foreign matter cannot stay in the pores, and the foreign matter cannot be caught persistently. The preferred lower limit for the average pore size is 30 zm, and the preferred upper limit is 300 x m. However, in the present invention, the average pore diameter of the porous soft body is not limited to this range.

[0174] Moreover, in a porous soft body, the softness is expressed as 30% compressive stress, and specifically, it is defined by the repulsive force when the thickness in the pressing direction of the porous soft body is compressed by 30%. Is done. In this embodiment, the 30% compressive stress of the porous soft body is preferably in the range of 1.5 to 98 kPa (15 to 1000 gf / cm ² ). If the 30% compressive stress is less than 1.5 kPa (15 gf / cm ² ), the force to scrub off foreign matter is too weak. If it exceeds 98 kPa (1000 gf / cm ² ), it will be too hard and the rubbing member (11) itself will work ( There is a risk of scratching the surface of 2). 30% pressure A preferable lower limit value of the compressive stress is 2.0 kPa (20 gfZcm ² ), and a preferable upper limit value is 49 kPa (500 gfZcm ² ).

[0175] As the porous soft body having the above average pore diameter and 30% compressive stress, any one of PVA resin, polyethylene resin, polyether resin, butyl acetate resin, and polyurethane resin is used. It is preferable to use a foam. These resins are used because the above average pore diameter and 30% compressive stress can be easily realized. Specifically, for example, PVA foam as a PVA resin foam, polyethylene foam as a polyethylene resin foam, polyether foam as a polyether resin foam, bull acetate foam as a vinyl acetate resin Examples of polyurethane resin foams include polyurethane foams. However, in the present invention, the porous soft body is not limited thereto.

[0176] The softness of the rubbing member (111), that is, the 30% compressive stress, depends on the type of resin, the average pore diameter, the porosity, the degree of polymerization of the resin, the content of the plasticizer, and the like. In this embodiment, the softness including these conditions is defined as 30% compressive stress.

[0177] In the hollow portion of the rubbing member (111), as shown in Figs. 9 and 10, the cleaning liquid supply pipe (112) is inserted and arranged tightly in the axial direction of the rubbing member (111). The cleaning liquid supply pipe (112) is for supplying the cleaning liquid (120) into the rubbing member (111). On the peripheral wall of the cleaning liquid supply pipe (112), for example, a large number of cleaning liquid outflow holes (112a) of φl to 4 mm are provided at intervals in the axial direction and the circumferential direction of the cleaning liquid supply pipe (112). Yes. The cleaning liquid supply pipe (112) has rigidity and can act as a core metal (core metal) for reinforcing the rubbing member (111). The cleaning liquid supply pipe (112) is made of, for example, resin or metal. Specifically, the axially intermediate portion of the cleaning liquid supply pipe (112) is made of resin, and the upper and lower ends are made of stainless steel.

As shown in FIG. 10, the upper end of the cleaning liquid supply pipe (112) is formed in a closed shape. On the other hand, the lower end of the cleaning liquid supply pipe (112) is open and the lower end is liquid-tight with the cleaning liquid introduction pipe (113) for introducing the cleaning liquid into the cleaning liquid supply pipe (112). It is connected to. The cleaning liquid is introduced from the cleaning liquid introduction pipe (113) into the cleaning liquid supply pipe (112). Entered. Then, the cleaning liquid in the cleaning liquid supply pipe (112) flows out from the cleaning liquid outflow hole (112a), whereby the cleaning liquid is supplied into the rubbing member (111). The supplied cleaning liquid (120) is uniformly exuded over the entire surface of the rubbing member (211) outside the surface of the rubbing member (111) through the continuous pores of the rubbing member (111).

[0179] The surface of the rubbing member (111) is in contact with the surface of the workpiece (2) along the length direction of the surface. In the present embodiment, the length of the surface of the rubbing member (111) is set to be larger than the length of the surface of the work (2), whereby the rubbing member (111) ) Surface can be brought into contact with the entire length of the surface of the workpiece (2).

[0180] Further, the scrub cleaning apparatus (110) includes two upper and lower workpiece support members (121) (121) for vertically supporting the workpiece (2). As shown in FIG. 11, each workpiece support member (121) has a fitting protrusion (121a) fitted into each of the upper and lower end surface openings of the workpiece (2). Further, as shown in FIG. 12A, the diameter D of each work support member (121) is set to be the same as the diameter (outer diameter) d of the work (2) (that is, D = d). Then, the fitting protrusion (121a) of the upper (one) workpiece support member (121) is coaxially fitted into the upper end opening of the workpiece (2), so that the upper end surface of the workpiece (2) is fitted. The upper work support member (121) is mounted. In this mounted state, the surface (outer peripheral surface) of the workpiece (2) and the peripheral surface of the upper workpiece support member (121) are continuous with each other in the axial direction of the workpiece (2). In addition, the fitting protrusion (121a) of the workpiece support member (121) on the lower side (the other side) is fitted coaxially into the opening on the lower end surface of the work (2), so that the work (2) The lower work support member (121) is attached to the lower end surface. In this mounted state, the surface of the workpiece (2) and the peripheral surface of the lower workpiece support member (121) are flush with each other. Thus, the workpiece (2) force is vertically supported by the individual workpiece support members (121) (121).

[0181] Here, as shown in Fig. 12A, the surface of the work (2) and the peripheral surface of each work support member (121) are flush with each other. When the surface of the member (111) is brought into contact with the entire length of the surface of the workpiece (2), the surface of the rubbing member (111) is securely attached to the upper end and lower end of the surface of the workpiece (2). It can be made to contact. On the other hand, as shown in FIG. 12B, if the diameter D of the workpiece support member (121) is larger than the diameter d of the workpiece (2), If the workpiece support member (121) is mounted on the end surface of the workpiece (2), the surface of the workpiece (2) and the workpiece support member (121) Since there is a step with the peripheral surface, even if you try to bring the surface of the scraping member (111) into contact with the upper end or lower end of the surface of the work (2), it cannot be brought into contact with this step. The upper and lower ends of the workpiece (2) surface cannot be cleaned. Therefore, when the workpiece support member (121) is mounted on the end surface of the workpiece (2), the surface of the workpiece (2) and the peripheral surface of the workpiece support member (121) are flush with the axial direction of the workpiece (2). It is desirable to be connected.

[0182] The rubbing member rotation drive device (115) has a motor (not shown) and a control unit (not shown) as drive sources, and is connected to the cleaning liquid supply pipe (112) of the rubbing member (111). Yes. Then, by driving the motor, the rubbing member (111) is rotated in its predetermined rotating direction (103) and the peripheral speed of the rubbing member (111) can be controlled by the control unit. Has been.

The work rotation drive device (116) has a motor (not shown) and a control unit (not shown) as a drive source, and a work support member (121) of the work (2) (in detail, the lower side) Connected to the workpiece support member). Then, by driving the motor, the workpiece (2) is rotated in its own axis in a predetermined rotation direction (104), and the peripheral speed of the workpiece (2) is configured to be controllable by the control unit. Les.

[0184] Further, the rubbing member (111) and the workpiece (2) are each rotated in their own directions in the same direction.

[0185] The pressing member (118) is a flat plate having one side edge portion extending in a straight line as the pressing portion (118a). The pressing member (118) has rigidity, and is made of, for example, plastic or metal. Desirably, the length of the pressing portion (118a) of the pressing member (118) is set to be the same or larger than the length of the surface of the workpiece (2). Desirably, it should be set to approximately the same size as the surface length.

[0186] The pressing member (118) is pressed against the surface of the rubbing member (111) during scrub cleaning and presses the rubbing member (111), and is pressed by an elastic means (not shown) such as a panel. A pressing force is applied to (118). Then, as shown in FIG. 9, in a state where the surface of the rubbing member (111) is pressed by the pressing member (118), the pressing member (118) The force S is disposed so as to be inclined rearward in the rotational direction (103) of the rubbing member (111), and the pressing member (118) is held by the holding means (not shown) in this inclined state. .

[0187] Next, a liquid hounging cage method using the liquid hounging force machine (1) will be described below.

[0188] First, as shown in Fig. 1, clean atmospheric gas is continuously supplied to the cleaning zone (6) in the housing (4) by the gas supply devices (58) and (67). As a result, the atmospheric gas pressure in the cleaning zone (6) is adjusted to a positive pressure relative to the outside air pressure outside the housing (4), and is also set to a positive pressure relative to the atmospheric gas pressure in the housing zone (5). adjust. The atmospheric gas pressure in the honing zone (5) is adjusted to a positive pressure with respect to the outside air pressure outside the housing (4). In other words, these pressure balances are adjusted so that the relationship of “cleaning zone (6)”> “hounging zone (5)”> “housing (4) outside” is established. In the present invention, in order to maintain this pressure balance, the partition wall (7) is provided with a small gas flow passage (not shown) or in one direction from the cleaning zone (6) to the honing zone (5). Gas flow passage (not shown), for example, a gas flow passage with a damper may be provided. By doing so, foreign matters can be reliably prevented from floating and flowing from the honing zone (5) into the cleaning zone (6). In the present invention, a gas flow passage (not shown) in one direction from the inside of the housing (4) to the outside thereof may be provided on the wall of the housing (4).

[0189] While maintaining such a state, a plurality of unprocessed workpieces (2) (seven in this embodiment) accommodated in the unprocessed workpiece accommodating portion (60) are collectively added to the fourth. The workpiece pitch change section of the hounging zone (5) in the housing (4) through the workpiece input port (4a) provided in the housing (4) by the transfer device (61). Transport to (42). Thereafter, the work insertion port (4a) is closed by an electric door (not shown).

[0190] At the next stage, the pitch of the plurality of workpieces (2) conveyed to the workpiece pitch changing section (42) is changed by the workpiece pitch changing section (42).

[0191] Next, the work (2) is transferred from the work pitch changing section (42) to the honing tank (30) through the work input port (35) by the first transfer device (43). Transport to honing section (31). Thereafter, the work inlet (35) and the outlet (36) are closed with the corresponding opening / closing lids (37) and (38). In this closed state, the workpiece (2) is known by the honing unit (31). Liquid houng treatment by the method.

[0192] This liquid hounging process will be briefly explained. As shown in Fig. 2, while the work (2) is rotating about its own axis, hounging liquid (70) is injected onto the surface of the work (2) by the spray nozzle (39) ( The outer peripheral surface is sprayed and the spray nozzle (39) is moved in the axial direction of the workpiece (2).

As a result, the entire surface of the workpiece (2) is subjected to the liquid honing process to be uniformly roughened.

[0193] In the next stage, the workpiece (2) subjected to the liquid houng treatment is transported from the hounging section (31) to the first shower cleaning section (32) by the transporting section (33).

[0194] Next, the workpiece insertion port (35) is opened, and a new unstressed workpiece (2) is moved from the workpiece pitch changing section (42) via the workpiece insertion port (35) by the first transport device (43). Then transport it to the Hounging section (31). Thereafter, the work insertion port (35) is closed with the opening / closing lid (37). Then, in this closed state, the unprocessed workpiece (2) is liquid hounged by the hounging part (31). At the same time, the workpiece (2) subjected to the liquid honing treatment is subjected to a shower washing process as a rough washing process by a known method in the first shower washing section (32).

[0195] This shower cleaning process will be briefly described. A cleaning liquid (71) is formed by a plurality of spray nozzles (40) arranged in the axial direction of the workpiece (2) while rotating the workpiece (2). ) Towards the surface of the cake (2). As a result, the entire surface of the workpiece (2) is cleaned. At this time, the cleaning liquid (71) is sprayed into the hollow portion of the work (2) to clean the inner surface of the work (2).

[0196] Next, the workpiece inlet (35) and the outlet (36) are opened. Then, the workpiece (2) that has been subjected to the cleaning process in the first shear cleaning section (32) is supplied to the cleaning zone (6). That is, the workpiece (2) is conveyed from the first shower cleaning section (32) to the submerged conveyance device (10) by the second conveyance device (44) through the workpiece outlet (36), and is conveyed to the conveyance table (12). It is mounted on the mounting plate (12a). Further, the work (2) subjected to the liquid houng treatment in the hounging part (31) is transported from the honing part (31) to the first shower cleaning part (32) by the transporting part (33). After that, a new unprocessed work (2) is transferred by the first transfer device (43) to the honing section (31) through the work input port (35).

Next, the work insertion port (35) and the take-out port (36) are respectively closed with the corresponding opening / closing lids (37), (38). Then, in this closed state, the unpowered work (2) is removed in the same manner as described above.

By doing this, foreign substances floating in the atmospheric gas in the houng zone (5) can be removed, and the cleanliness of the houng zone (5) can be improved.

[0200] Further, when at least one of the work inlet (35) and the outlet (36) of the honing tank (30) is open, the honing tank gas suction device (41) is operated to perform the honing. The atmospheric gas in the tank (30) is sucked by the gas suction device (41), while the gas suction device for the horn zone (45) is not operated. As a result, foreign matter floating in the atmospheric gas in the honing tank (30) flows out to the hounging zone (5) through at least one of the workpiece inlet (35) and the outlet (36). Can be reliably prevented and the cleanliness of the hounging zone (5) can be maintained.

In this state, the workpiece is passed from the honing zone (5) to the cleaning zone (6) through the workpiece passage opening (8) in the partition wall (7). It is desirable that the conveying speed of the workpiece (2) is set within a range in which the workpiece (2) can be maintained in the state of being wrapped in the bubbles (21), for example, 50 to 100 mm / s (preferably 60 to 90 mm / s). It can be set within the range of s). Moreover, it is preferable to set the conveyance time of the workpiece (2), that is, the residence time of the workpiece (2) in the liquid within a range of 15 to 40 seconds.

It may be used as a part. In addition, clean water is appropriately supplied to the fourth recovery tank (87d).

Therefore, the liquid honing machine (1) and the liquid honing method have the following advantages.

[0237] According to the liquid hounging machine (1), the liquid hounging process and the cleaning process can be sequentially performed on the workpiece (2), so that mass productivity is improved.

[0238] Further, between the honing zone (5) and the cleaning zone (6) in the housing (4). Since the partition wall (7) is provided, foreign particles such as abrasive dust floating in the atmosphere gas in the hounging zone (5) flow into the cleaning zone (6). Can be prevented. Therefore, contamination of the cleaning zone (6) due to the inflow of foreign matter floating in the atmospheric gas in the honing zone (5) to the cleaning zone (6) can be prevented.

[0239] In addition, the work (2) subjected to the liquid houng treatment in the hounging zone (5) is immersed in the liquid (72) in the transfer tank (11) by the submerged transfer device (10). Therefore, when the workpiece (2) is transferred, the workpiece (2) is transferred from the hounging zone (5) through the workpiece passage opening (8) of the partition wall (7) and transferred to the cleaning zone (6). ) Is immersed in the liquid (72) in the transfer tank (11), foreign matters such as abrasive grains and dust adhering to the workpiece (2) are removed. Therefore, it is possible to prevent foreign matter adhering to the workpiece (2) from being brought into the cleaning zone (6) together with the workpiece (2) while remaining attached to the workpiece (2). It is possible to prevent contamination of the cleaning zone (6) due to foreign matter adhering to 2) being brought into the cleaning zone (6).

[0240] That is, according to this liquid honing machine (1), contamination of the cleaning zone (6) due to the inflow of foreign matter floating in the atmosphere gas of the honing zone (5) into the cleaning zone (6) is prevented. In addition, it is possible to prevent contamination of the cleaning zone (6) by bringing foreign matter adhering to the workpiece (2) into the cleaning zone (6). ) Can be maintained at a high level of cleanliness. Therefore, it is possible to prevent the occurrence of poor cleaning.

[0241] Also, the upper edge (8a) of the workpiece passage opening (8) of the partition wall (7) is the transfer tank of the submerged transfer device (10).

(11) Since it is immersed in the liquid (72) inside, the foreign matter floating in the atmosphere gas in the hounging zone (5) passes through the workpiece passage opening (8) and passes through the cleaning zone ( 6) can be reliably prevented. Therefore, the cleanliness of the cleaning zone (6) can be reliably maintained.

[0242] In addition, since the rail part (l id) is not immersed in the liquid (72) in the transfer tank (11), the hanging part (12c) can slide with the rail part (l id). The accompanying dust can be prevented from flowing into the liquid (72) in the transfer tank (11). Therefore, contamination of the liquid (72) in the transfer tank (11) due to the outflow of the dust into the liquid (72) in the transfer tank (11) can be prevented.

[0243] Further, the moving path (13) and the rail part (lid) of the hanging part (12c) are covered by the cover member (14). As a result, the dust generated by sliding with the rail (lid) of the hanging part (12c) is scattered outside (hounging zone ( ₅ ) and cleaning zone ( ₆ )). This can be prevented by the cover member (14). Therefore, it is possible to maintain the cleanliness of the cleaning zone (6) more reliably.

[0244] Furthermore, the lower end (14c) of the side wall (14b) on the inner side of the transport tank (11) in the cover member (14) is immersed in the liquid (72) in the transport tank (11). Therefore, it is possible to reliably prevent the dust from scattering to the outside.

[0245] Further, the bubbles (21) are generated in the liquid (72) in the transfer tank (11) by the bubble generating means (17), while the work (2) is transferred to the liquid (72 in the transfer tank (11). When the workpiece (2) is transported to the cleaning zone (6) while being immersed in the workpiece (2), foreign matter adhering to the workpiece (2) can be effectively removed during the transport of the workpiece (2). ) Can be reliably prevented from entering the cleaning zone (6).

[0246] Further, the liquid (72) is ejected into the transport tank (11) by the ejection nozzle (19) so that the liquid (72) flows in the direction opposite to the work transport direction (3) in the transport tank (11). While being fed, the workpiece (2) is transported while being immersed in the liquid (72) in the transport tank (11), thereby being present in the liquid (72) in the transport tank (11). The foreign matter removed from the work (2) is moved to the hounging zone (5) side in the transfer tank (11) by the liquid flow in the transfer tank (11). As a result, contamination of the cleaning zone (6) can be more reliably prevented.

[0247] Further, the liquid (72) is ejected into the transport tank (11) from the cleaning zone (6) side of the transport tank (11) by the spray nozzle (19), therebyヮ just before being pulled out of the liquid (72) → The force that can force the liquid (72) to be ejected toward the work (2) at a position close to (2) The removal rate is improved.

[0248] Further, when the workpiece (2) is transferred by the submerged transfer device (10), the liquid (72) in the transfer tank (11) is transferred to the hounging zone (5) side wall of the transfer soda (11). By overflowing from the upper end of the part (lib), the foreign matter floating on the liquid level in the transfer tank (11) overflows together with the liquid (72) in the transfer tank (11) and flows out of the transfer tank (11). Is discharged. Therefore, it is possible to prevent a decrease in the cleanliness of the liquid (72) in the transfer tank (11), and it is possible to prevent foreign matters from reattaching to the work (2) when the work (2) is transferred. In addition, foreign matter that floats on the liquid level in the transfer tank (11) Is discharged from the upper end of the side wall (lib) on the honing zone (5) instead of the side wall (11c) on the cleaning zone (6) side of the transfer tank (11). There is no risk of contamination of the cleaning zone (6).

[0249] In addition, while lifting the work (2) from the liquid (72) in the transfer tank (11), the cleaning liquid (73) is sprayed by the spray nozzle (23) toward the work (2), The force S can be removed when the workpiece (2) is transported or lifted, and the foreign matter that has reattached to the workpiece (2) is removed while the workpiece (2) is being lifted.

[0250] In addition, since the bottom surface (l ie) of the transfer tank (11) is formed to be inclined upward in the workpiece transfer direction (3) with respect to the horizontal plane, the liquid in the transfer tank (11) ( 72) The foreign matter that has settled down slides on the bottom surface (ie) of the transfer tank (11) and moves to the honing zone (5) side in the transfer tank (11). Therefore, contamination of the cleaning zone (6) can be more reliably prevented.

[0251] In addition, cleaning is performed at the time of cleaning by cleaning the workpiece (2) in the cleaning zone (6) while supplying clean atmospheric gas to the cleaning zone (6) by the gas supply device (58) (67). The cleanliness of the zone (6) can be improved.

[0252] Further, since the liquid houng processing machine (1) is equipped with a gas suction device (45), by sucking the atmospheric gas in the honing zone (5) by this gas suction device (45), the hounging machine (1) Foreign substances floating in the atmospheric gas in the zone (5) can be removed, and the cleanliness of the honing zone (5) can be improved.

[0253] In addition, by cleaning the work (2) in the cleaning zone (6) with the atmospheric gas pressure in the cleaning zone (6) adjusted to a positive pressure relative to the outside air pressure outside the housing (4), (4) It is possible to prevent the outside air from flowing into the cleaning zone (6) from the gap inevitably generated in the housing (4), and to ensure the cleanliness of the cleaning zone (6). I can do it.

[0254] In addition, the workpiece (2) should be cleaned in the cleaning zone (6) with the atmospheric gas pressure in the cleaning zone (6) adjusted to a positive pressure relative to the atmospheric gas pressure in the hounging zone (5). As a result, the atmospheric gas in the honing zone (5) is removed from the gaps inevitably generated between the partition wall (7) and the housing (4) or between the partition wall (7) and the transfer tank (11). 6), and the cleanliness of the cleaning zone (6) can be maintained reliably. wear.

[0255] In the hounging zone (5), the hounging section (31), the shower cleaning section (32), and the transport section

Since the honing tank (30) having (33) inside is disposed, the houng zone (5) can be prevented from being contaminated during the liquid honing process.

[0256] Further, when at least one of the work inlet (35) and the outlet (36) of the honing tank (30) is opened, the atmospheric gas in the honing tank (30) is used as the honing tank gas. By sucking with the suction device (41), foreign matter floating in the atmospheric gas in the honing tank (30) is passed through the at least one of the workpiece inlet (35) and the outlet (36) to the honing zone. (5) can be reliably prevented from flowing out, and the cleanliness of the honing zone (5) can be maintained.

[0257] In addition, in the cleaning zone (6), it is transferred to the workpiece (2) transferred to the cleaning zone (6), shower cleaning treatment, two scrub cleaning treatments, shower cleaning treatment, immersion. By sequentially performing the cleaning process and the pull-up drying process, the cleaning efficiency of the workpiece (2) can be further improved.

[0258] Further, the scrub cleaning sections (52a) and (52b) of the cleaning zone (6) scrub the workpiece (2) with the scrub cleaning device (110).

[0259] That is, since the rubbing member (111) of the scrub cleaning device (110) is composed of a porous soft body having continuous pores, the surface of the rubbing member (111) is brought into contact with the surface of the workpiece (2). In addition, foreign matters such as burrs, abrasive grains, and dust existing on the surface of the work (2) can be taken into the pores on the surface of the rubbing member (111) and captured with a tenacity. For this reason, foreign matters can be reliably removed from the surface of the workpiece (2).

[0260] Furthermore, since the workpiece (2) is being washed out while leaching the cleaning liquid (120) from the inside of the rubbing member (111) to the outside of the surface of the member (111) that is rubbed through the continuous pores, Foreign matter adhering to the surface of the rubbing member (11) and foreign matter trapped in the pores can be discharged to the outside by the cleaning liquid (120) that exudes to the outer surface of the rubbing member (111). Further, by pressing the surface of the rubbing member (111) with the pressing member (118), a cleaning liquid (120 for discharging foreign matter at the pressed portion of the pressing member (118) on the surface of the rubbing member (111) (120). ) Will exude a large amount from the inside of the rubbing member (111). Can be discharged. In addition, at this time, the foreign matter trapped in the pores may float on the surface of the rubbing member (111) due to contact with the pressing member (118), and the foreign matter may be easily removed. The amount of discharge can be increased. For this reason, it is possible to prevent the foreign matter from reattaching to the surface of the workpiece, and the workpiece (2) generated when the foreign matter remaining in the pores of the surface of the scraping member (111) contacts the surface of the workpiece (2). Surface damage can be prevented. Therefore, the incidence of surface defects on the workpiece (2) can be reduced.

[0261] Further, by cleaning the workpiece (2) by rotating the rubbing member (111) and the workpiece (2) in the same direction in the same direction, foreign matter can be removed from the surface of the workpiece (2). Can be removed reliably.

[0262] In this scrub cleaning method, it is desirable to set the peripheral speed of the rubbing member (111) in the range of 100 to 500 mm / s (particularly preferably 200 to 300 mm / s). Further, it is desirable to set the peripheral speed of the cake (2) in the range of 50 to 200 mm / s (particularly preferably 75 to 150 mm / s). Thus, by setting the peripheral speed of the rubbing member (111) and the peripheral speed of the work (2) within predetermined ranges, the force S can be removed more reliably from the surface of the work (2).

[0263] In order to ensure that the peripheral speed of the rubbing member (111) can be set within the above range, the rubbing member rotation drive device (115) sets the peripheral speed of the rubbing member (111) to at least 0 to 650 m. It is desirable to be configured to be controllable within a range of m / s. In addition, in order to ensure that the peripheral speed of the work (2) can be set within the above range, the work rotation drive device (16) can control the peripheral speed of the work (2) to at least the range of 0 to 300 mmZs. It is desirable that it is configured as follows.

[0264] Furthermore, the workpiece (2) is cleaned in a state where the surface of the scraping member (111) is in contact with the surface of the workpiece (2) along the length direction of the surface of the workpiece (2). As a result, the amount of foreign matter removed from the work surface can be increased.

[0265] Further, as shown in FIG. 9, the surface of the scraping member (111) was brought into contact with the surface of the work (2) so that the contact width W with the work surface was within a range of 5 to 30 mm. In this condition, it is desirable to clean the workpiece (2). If W is less than 5mm, W is too small and cleaning power is insufficient. on the other hand If W exceeds 30 mm, the pressing force of the rubbing member (111) against the workpiece surface becomes too strong, and the surface of the workpiece (2) is easily damaged. Therefore, if it is desired that W is in the range of 5 to 30 mm, foreign matter can be reliably removed, and the pressing force of the scraping member (111) to the workpiece (2) surface is strong. It is possible to prevent the problem that the surface of the workpiece (2) is damaged by becoming too much. A particularly preferable range of W is 10 to 15 mm. However, in the present invention, W is not limited to this range.

[0266] Furthermore, the workpiece (2) is cleaned in a state where the surface of the scraping member (111) is in contact with the entire surface of the workpiece (2) in the longitudinal direction of the workpiece (2). Therefore, foreign matter can be removed over the entire length of the surface of the work (2).

[0267] Furthermore, since the workpiece support member (121) is mounted on the end surface of the workpiece (2) so that the surface of the workpiece (2) and the peripheral surface of the workpiece support member (121) are connected to each other. The surface of the scraping member (111) can be brought into contact with the end of the surface of the work (2) with certainty, and the end of the surface of the work (2) can be reliably cleaned.

[0268] Further, in this scrub cleaning method, as shown in FIG. 6, the pressing member (118) is rubbed in a state where the surface of the rubbing member (111) is pressed by the pressing member (118), and the pressing member (118) is rubbed ( 111) It is desirable to incline in the rotation direction (103) rear side. By doing so, it is possible to reliably discharge the foreign matter adhering to the surface of the rubbing member (111) and the foreign matter trapped in the pores to the outside.

[0269] Furthermore, as shown in the figure, if the angle formed between the pressing member (118) and the surface of the rubbing member (111) in the rotational direction (103) rear side is Θ, Θ is 10 to 45 ° ( Particularly preferably, it is desirable to set in the range of 20 to 30 °. By doing so, foreign matter can be more reliably discharged to the outside. However, in the present invention, Θ is not limited to this range.

[0270] Further, as shown in the figure, the surface of the rubbing member (111) is formed on the surface so that a recess (119) having a depth K of 0.5 to 5 mm (particularly preferably 1 to 3 mm) is generated. It is desirable to press with the pressing member (118). In this way, foreign matter can be more reliably discharged to the outside.

[0271] The pressing member (118) is a plate-shaped member having one side edge as the pressing portion (118a). By pressing the surface of the scraping member (111) with the plate-shaped pressing member (118), a large amount of the cleaning liquid (120) can be surely exuded from the inside of the scraping member (111), and foreign matter can be removed. It is possible to discharge reliably to the part. Moreover, by using this plate-like pressing member (118), the foreign matter trapped in the pores can be easily removed, and the amount of foreign matter discharged can be reliably increased. .

[0272] Furthermore, since the cleaning liquid supply pipe (112) is inserted into the hollow portion of the rubbing member (111), the cleaning liquid (120) can be reliably supplied into the rubbing member (111). further

Since the cleaning liquid supply pipe (112) inserted into the hollow portion of the rubbing member (111) acts as a metal core for reinforcing the rubbing member (111), the surface of the rubbing member (111) is used as the surface of the workpiece (2). It can be brought into contact with tension.

[0273] Furthermore, since the workpiece (2) and the rubbing member (111) are arranged vertically, the cleaning liquid (120) that has taken in the foreign matter moves over the surface of the workpiece (2) and the rubbing member (111) during cleaning. It will flow down in the axial direction and foreign matter can be removed quickly.

[0274] Furthermore, since the lower end of the cleaning liquid supply pipe (112) is connected to the cleaning liquid introduction pipe (113),

Even if the cleaning liquid leaks out from the connecting portion between the lower end of the cleaning liquid supply pipe (112) and the cleaning liquid introduction pipe (113), the cleaning liquid that has taken in the foreign material at the time of the leakage is rubbed (11

The problem of adhering to and contaminating the surface of 1) can be prevented.

[0275] Although one embodiment of the present invention has been described above, the present invention is not limited to the one shown in the above embodiment, and various settings can be changed.

[0276] For example, the workpiece (2) to be machined by the liquid honing machine according to the present invention may be an element tube of a precision neuve such as a pipe for a lens barrel of an optical device (eg, a camera or a telescope). It may be a blank tube used for other purposes.

[0277] Further, the number of scrub cleaning units (52a) and (52b) arranged in the cleaning zone (6) may be three or four or more.

[0278] Further, the workpiece (2) may be a columnar one, not limited to a cylindrical one.

[0279] Further, the rubbing member (111) of the scrub cleaning device (110) may be a columnar one, not limited to a cylindrical one. [0280] In the scrub cleaning device (110), the lower end of the cleaning liquid supply pipe (112) is formed in a closed shape, while the upper end of the cleaning liquid supply pipe (112) is connected to the cleaning liquid introduction pipe (113). It is okay.

[0281] Next, specific examples and comparative examples of the present invention are shown below.

As work (2), 5,000 photosensitive drum base pipes were prepared. This work (2) (element tube) consists of an aluminum drawn round tube with a length of 200 to 450 mm, an outer diameter of 15 to 50 mm, and a wall thickness of 0.2 to 2 mm. is there. The workpiece (2) was subjected to liquid houng processing by the liquid honing machine (1) of the above embodiment.

[0283] <Comparative Example 1>

However, in this comparative example 1, the partition wall (7) is not disposed between the hounging zone (5) and the cleaning zone (6) in the housing (4), and the submerged transfer device ( The workpiece (2) was transported from the hounging zone (5) to the cleaning zone (6) without using 10). Other conditions are the same as in Example 1.

[0284] The cleaning failure rate of the workpiece (2) treated in liquid hounging in Example 1 and Comparative Example 1 was examined.

[0285] As a result, in Comparative Example 1, the cleaning failure rate of the workpiece (2) was 1.5%. On the other hand, in Example 1, the cleaning failure rate was 0.05. /. Met. Therefore, it was confirmed that the cleaning failure rate of the workpiece can be greatly reduced by subjecting the workpiece (2) to the liquid houng treatment by the liquid hounging machine (1).

[0286] The cleaning failure rate was determined as follows.

[0287] Visual inspection of the pipe of the pipe for the photosensitive drum substrate as the work (2) was performed under a yellow lamp illumination, and a product that passed this inspection was liquidated by the liquid honing machine (1) of the above embodiment. Honed.

[0288] Next, visual inspection of the workpiece (2) that had been subjected to the liquid houng treatment was again performed under a yellow lamp illumination. Then, the presence or absence of scratches due to abrasive grains and rubbing cleaning is examined, and those without abrasive grains and scratches are accepted, and those that are present are judged to be poorly washed. It was.

[0289] <Example 2 to 16>

As work (2), 5,000 photosensitive drum base pipes were prepared. This work (2) (element tube) consists of an aluminum drawn round tube with a length of 200 to 450 mm, an outer diameter of 15 to 50 mm, and a wall thickness of 0.5 to 2 mm. is there. The surface of the workpiece (2) was subjected to liquid houng treatment by the liquid hounging machine (1) of the above embodiment. Then, the incidence of defects due to circumferentially generated scratches on the surface of the workpiece (2) was examined. The results are shown in Table 1.

[0290] Of the liquid honing treatment, the rubbing member (111) used in the scrub cleaning treatment is a PVA foam having a 30% compressive stress of 8.8 kPa (90 gf / cm ² ) and an average pore diameter of 200 / im. It consists of a porous soft body with continuous pores formed by Also, the peripheral speed of the scraping member (111), the peripheral speed of the workpiece (2), the contact width W of the surface of the scraping member (111) with the surface of the workpiece (2), the pressing member (118) and the scraping member (111 ) And the depth K of the dent (119) on the surface of the rubbing member (111) were set to the values shown in Table 1 and scrub cleaning was performed. .

[0291] <Comparative Example 2>

As the work (2), 5,000 pieces of the same raw tubes used in Examples 2 to 16 were prepared. The surface of the cake (2) was cleaned by the scrub cleaning sections (52a) and (52b) by the same scrub cleaning treatment as in Examples 2 to 16 except that the pressing member (118) was not used. Then, the incidence of defects due to the circumferentially extending scratches generated on the surface of the workpiece (2) was examined. The results are shown in Table 1

[0293] As shown in Table 1, in Examples 2 to 16, it was confirmed that the defect occurrence rate could be reduced as compared with Comparative Example 2.

[0294] Gu Comparative Example 3>

Work (2) was subjected to liquid honing. However, in Comparative Example 3, the work (2) was scrubbed by the following method. That is, the scrub cleaning method is to rotate the rubbing member (111) by rotating the rubbing member (111) with the rubbing member (111) in contact with the surface of the workpiece (2). The surface was scrubbed. However, during this cleaning, the cleaning liquid is not leached from the inside of the rubbing member (111) to the outer surface of the rubbing member (111). However, the pressing member (118) was not used. Other conditions are the same as those in Examples 2 to 16. Then, the occurrence rate of defects due to the circumferentially extending flaw generated on the surface of the workpiece (2) was examined.

[0295] As a result, in Comparative Example 3, the defect occurrence rate due to this scratch was 1.74%. This scratch is caused by the foreign matter trapped in the pores on the surface of the rubbing member coming into contact with the surface of the cake as the rubbing member rotates. On the other hand, in Examples 2 to 16, the defect occurrence rate due to this scratch is about 0% (more specifically, 0.05% or less), and therefore it is confirmed that the defect occurrence rate can be greatly reduced as compared with Comparative Example 3. It was possible.
