Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cleaning method and a cleaning device, and more particularly, the present invention relates to a cleaning method and a cleaning device, and more particularly to a method for effectively removing cutting debris generated by cutting a cylinder block by alternately jetting gas and liquid. The present invention relates to a cleaning method and a cleaning device.

For example, when cutting is performed on a cast product that constitutes an engine, such as when a jacket hole is bored in a cylinder block, the cutting waste generated by the cutting process must be effectively removed.

Generally, in the automobile industry, cleaning devices are employed to automatically remove cutting waste from relatively large workpieces such as cylinder blocks. This type of cleaning device consists of a liquid cleaning device and an air blow device. That is, a line is extended from the cutting device on the upstream side to the downstream side, and the tunnel mechanism is arranged along this line. A liquid cleaning device and an air blowing device are arranged with respect to this tunnel mechanism so as to be separated from each other by a predetermined distance.

Therefore, it is cut by a cutting machine, and for this reason,
A workpiece with cutting debris adhered to it is introduced into the tunnel, and first, the liquid cleaning device is energized. As a result, the cutting debris is washed away, and then air at a predetermined pressure is ejected from the air blowing device to the workpiece that has arrived just before the air blowing device, and the adhering cutting debris is further blown off together with the cleaning fluid. It turns out. In this case, the liquid cleaning device and the air blowing device are each equipped with a plurality of nozzles that spray liquid and air onto the workpiece, and the number of nozzles varies depending on the type of workpiece to be cleaned. The ejection part is configured to be movable.

In other words, there is a water splash in the engine block7)
Holes for water and oil are formed by cutting at different angles, but holes at various angles can be cleaned all at once using a single liquid cleaning device and air blow device. It is extremely difficult. For this reason, when cleaning holes with different angles, multiple cleaning devices are arranged along the line and the angle of each nozzle is changed to correspond to the angle of the hole. The cleaning fluid is spouted out.

However, the cleaning equipment according to the prior art configured in this way has an abnormally long line compared to the processing equipment before and after it including the cutting equipment (therefore, the cleaning equipment occupies less space in the factory). The area must be extremely large.

Furthermore, if workpieces of different models are passed through the same production line, the positions of the nozzle of the liquid cleaning device and the nozzle of the air blowing device must be changed according to the shape of the workpieces, and the adjustment is extremely complicated. However, there was an inconvenience that it required a long time.

Therefore, the inventors of the present invention have conducted extensive research and devised new ideas, and have discovered that depending on the shape of the workpiece, it is possible to rotate the workpiece and spray cleaning liquid and compressed air to clean it.
A workpiece is rotated inside the housing, a plurality of nozzle blocks are arranged for the workpiece, and cleaning liquid and compressed air are alternately jetted from each nozzle block in response to the rotation of the workpiece. With this configuration, the area occupied by the cleaning equipment on the production line is significantly reduced, and cleaning liquid and compressed air can be supplied to holes drilled in the workpiece at different angles simply by rotating the workpiece. This makes it possible to easily and reliably feed the cleaning liquid, etc. to a designated hole, and for this reason, there is no need to adjust the nozzle angle, which was required with conventional technology, making it more efficient. Moreover, it has been found that the cylinder block, etc. can be cleaned in a short time, and the various inconveniences mentioned above can be solved at once.

Therefore, an object of the present invention is to have a simple structure, do not occupy a large area, and supply cleaning liquid and compressed air to the workpiece from various angles, thereby easily and reliably removing cutting debris generated during cutting. An object of the present invention is to provide a cleaning method and a cleaning device that enable cleaning.

In order to achieve the above object, the present invention transports a workpiece into a chamber defined by a plurality of nozzle blocks, clamps the workpiece, and injects a cleaning device into a predetermined position of the workpiece from a nozzle hole of the nozzle block. Next, the workpiece is once led out of the room, and then the workpiece is transported into a chamber defined by a different nozzle block and clamped, and the nozzle of the nozzle block is placed at a different position on the workpiece. The feature is that the workpiece is cleaned by ejecting cleaning fluid from the hole.

Furthermore, the present invention has a shaft that is rotatably supported and has a fluid passage connected to a fluid supply pipe to introduce cleaning fluid, and a passage that is held by the shaft and communicates with the fluid passage. a nozzle block holder; a plurality of nozzle blocks having nozzle holes that are attached to the nozzle block holder and feed cleaning fluid to different positions with respect to the workpiece; and a conveyor for positioning the workpiece with respect to the nozzle block. It is characterized by including means.

Similarly, the cylinder rod 26a of the second cylinder 26 is also inserted into the second cylinder from between the rail members 22.22.
The cylinder rod 28a of the third cylinder 28 can also be displaced from between the rail members 22, 22 toward the opening 15a.

Next, a guide member 3 is attached to each of the transport tables 3-Oa and 30b.
3a and 38b are erected, the pedestal 34a engages with the guide member 38a, and the pedestal 34b engages with the guide member 38b.
engage with. That is, a holding member 40a that is bent in cross section is removably attached to the upper surface of the pedestal 34a, and a nozzle block 42a that contacts the lower surface of the workpiece is fixed to the upper part of the holding member 40a. The guide member 38a is inserted into a hole (not shown) formed in the holding member 40a1 and the nozzle block 42a, and

Similarly, a bendable holding member 40b is removably arranged on the upper part of the pedestal 34b, and a nozzle block 42b that contacts the lower surface of the workpiece is mounted and fixed on the upper part of this holding member 40b. Similarly to the above, the nozzle block 42b
A hole (not shown) is formed in the holding member 40b, and the guide member 38b is inserted into the hole so that the nozzle block 42b and the holding member 40b can be displaced in the vertical direction.

At the upper ends of the nozzle blocks 42a and 42b, for example,
A hole 43a that sufficiently holds an uneven workpiece such as a cylinder head and communicates with a hole drilled in the workpiece;
43b is formed, and the holes 4 are formed inside the nozzle blocks 42a and 42b, respectively.
A passage 46 is defined in communication with 3a and 43b for supplying cleaning liquid and compressed air to the workpiece W. This passageway 46 can engage a fluid supply tube 48 for supplying cleaning fluid as well as air.

That is, as can be easily understood from FIG. 2, a hollow guide member 50 is supported on the side of the second housing 14 and extends in the horizontal direction, and a fluid supply pipe is installed inside the guide member 50. 48 is slidably disposed. The fluid supply pipe 48
Joint 5 for supplying cleaning liquid and compressed air to the end of
2 is engaged, and this joint 52 further includes a cylinder 5.
No. 4 cylinder rods 56 are engaged. Note that one end of the joint 52 is connected to a flexible tube 57 for cleaning and supplying compressed air to the lower surface nozzle block 42a.
is connected. Therefore, when the cylinder 54 is energized, the cylinder rod 56 connects the fluid supply pipe 48 and the joint 52.
It will be easily understood that the distal end of the fluid supply pipe 4 can be fitted into the passage 46 and secured together.

Next, in the above configuration, the second housing 14 has one
A pair of work clamp cylinders 58 and 60 are arranged to face each other. In this case, the cylinder rod 58a of the work clamp cylinder 58 is connected to a shaft 64a via a joint 62a, and a cylindrical body 66a is connected to the tip of the shaft 64a. Note that the cylindrical body 66a has a cylindrical sliding member 67a engaged with the shaft 64a at its tip.

On the other hand, the cylinder rod 6 of the work clamp cylinder 60
0a is connected to the shaft 64b via a joint 62b. The tip of this shaft 64b is connected to a cylindrical body 66b, and a cylindrical sliding member 67b that engages with the shaft 64b is engaged at the tip of the cylindrical body 66b, similarly to the cylindrical body 66a. As can be easily understood from FIG. 2, in this case, the axis 6
4b is longer in length than said shaft 6.4a, and a spline 68 is cut into this shaft 64b.

Therefore, a first gear 70 is engaged with the spline 68.

This gear 70 is connected to a motor 7 supported by a support plate 72.
It meshes with a second gear 78 that is pivotally attached to the rotational drive shaft 76 of No. 4.

Next, above the work clamp cylinder 58 is a fluid supply pipe 8° for supplying cleaning liquid and cleaning air.
0 is arranged so as to be freely displaceable in the horizontal direction. That is, the cylinder 82 is attached to the housing 14, and the fluid supply pipe 8
0 can be inserted into the inside of the cylinder 82 and connected to the fluid supply port of the nozzle block holder.

Next, this nozzle block holder and the shaft 84 that holds the nozzle block holder at both ends thereof will be explained.

First, bearings 85a and 86b are provided in the housing 14, and the shaft 84 is rotatably supported by the bearings 86a and 86b. A housing 14 is attached to one end of this shaft 84.
a motor 88 external to the shaft 84 for rotating the shaft 84;
A rotary drive shaft 88a is connected to the rotary drive shaft 88a. As can be easily understood from FIGS. 1, 4, etc., the shaft 84 is configured to have a square cross section, and its interior is divided into passages 92a, 92a and 90b by cross-shaped partition walls 9Qa and 90b.
92b, 92c and 92d are defined. In this case, the passages 92a to 92d communicate with the outside through openings 94a to 94d, and nozzle blocks 95a to 95d are provided in the central portions of the four sides of the shaft 84 to spray cleaning fluid onto the workpiece at different positions. (See Figure 1).

Next, the first nozzle block holder 100a and the second nozzle block holder 100b, which are attached to both ends of the shaft 84 configured as described above, will be explained.

As shown in FIGS. 3 and 4, the nozzle block holder 100a has a body 101 with a square shape in front, and cylindrical bodies 102a, 102b, 102c and 102d extend in the axial direction of the cylinder 82 at the corners thereof. configured to do so. Moreover, the cylindrical body 10 is attached to the body 101.
A circular pipe 104a that opens inside 2a to 102d.
104d to 104d are formed. As shown in FIG. 2, these conduits 104a to 104d communicate with holes 108 in shaft 84 via inclined surfaces 106, and holes 108 communicate with openings 94a to 94d via passages 92a to 92d.
They communicate with each other.

Therefore, the openings 94a to 94d are configured to communicate with passages 110a to 110d extending from the body 101 to the cylindrical bodies 102a to 102d, respectively. The respective passages 110a to 110d are connected to the cylindrical bodies 102a to 1
Pathways 112a, 112 that branch off in the middle of 02d
b, 114a, 114b, 116a, 116b,
118a and 118b.

In this case, the passages 112b and 114a are connected to the body 101.
The passages 122a and 122b are connected to the passages 122a and 122b bored in the casing 120a which is bulged to the outside of the housing.
2a and 122b are communicatively connected to a triangular prism-shaped fluid introduction pipe 123a. On the other hand, the passages 114b and 116a are connected to the housing 120.
These passages 124a, 124b communicate with a triangular prism-shaped fluid introduction pipe 123b. Furthermore, passages 116b, 11
8a are passages 126a and 12 bored in the housing 120c.
6b and these passages 126a, 126b.
communicates with the fluid introduction pipe 123c. Furthermore, passage 1
18b and 112a are passages 12 bored in the housing 120d.
8a, 128b and these passages 128a.
, 128b are connected to the fluid introduction pipe 123d.

In this case, the passage 122a communicates with a nozzle hole (not shown) of a nozzle block 130a fixed along the axial direction of the cylinder 82 via the introduction pipe 123a, and
The passage 122b also communicates with the nozzle hole of the nozzle block 130b. Further, the passage 124a communicates with the nozzle hole of the nozzle block 130c via the introduction pipe 123b, and the passage 124b similarly communicates with the nozzle hole of the nozzle block 130d. The passageway 126a is then connected to the inlet tube 1
The passage 126b is connected to the nozzle hole of the nozzle block 130e through the nozzle hole 23c.
It communicates with the nozzle hole of 0f. Furthermore, passage 128a
communicates with the nozzle hole of the nozzle block 130g via the introduction pipe 123d, and the passage 128b similarly communicates with the nozzle hole of the nozzle block 130h.

On the other hand, nozzle holding members 134a to 134d having cylindrical conduits 132a to 132d that are partially fitted into the cylindrical bodies 102a to 102d are slidably engaged, and each of the nozzle holding members 134a to 134d is connected to a pair of nozzle holding members 134a to 134d. The nozzle blocks 136a to 136d are removably held therein.

The nozzle block holder 100b has approximately the same configuration as the nozzle block holder 100a, and the pipe line 1
The difference is that it does not have 04a to 104d.

In the figure, reference numeral 140 indicates a mist collector that is connected to the cleaning device 10 and absorbs cleaning liquid and air.

The cleaning method and cleaning apparatus according to the present invention are basically constructed as described above, and their functions and effects will be explained next with reference to the time chart shown in FIG. 6.

First, when the work w1 arrives at the end of the first housing 12 by a transport device (not shown), the cylinder 28 is energized.
The pedestal 34b, which is engaged with the cylinder rod 28a of the cylinder 28, rises together with the holding member 40b to support the workpiece W1. In this case, a nozzle block 42b is fixed to the upper part of the holding member 40b, and this nozzle block 42b engages with the bottom of the workpiece W1 to firmly hold it. Then, the cylinder 28 is driven again and the workpiece W1 is lowered. The pedestal 34b that has reached the inside of the first casing 12 is connected to the hole 36 of the transport platform 30b.
b, and here it engages with the conveyance table 30b. Next, the conveyor table 30b moves on the rail member 22 with rollers 32b,
32b is conveyed by a drive device (not shown) and moved to just below the second casing 14. This is the so-called traverse transport shown in the time chart (see Fig. 6, ■). At this time, the cylinder rod 28a is slightly lowered and released from the pedestal 34b in advance. Due to this movement of the conveyance table 30b, the conveyance table 30a, which was already positioned directly below the second casing 14, moves to the cylinder 24 side. Note that the conveyance table 30b performs the same operation in relation to the conveyance table 30a and the second casing 14, so here it is referred to as the conveyance table 30a.
I will explain about it.

The pedestal 34a that engages with the conveyor table 30a on the cylinder 26 is moved by the cylinder rod 26a under the driving action of the cylinder 26.
performs a rising operation, so that it rises toward the second housing 14 side.

Since the nozzle block 42a is positioned on the holding member 40a disposed on the pedestal 34a, the workpiece W2 on the nozzle block 42a enters the inside of the second housing 14 (see FIG. 6, ■). When it reaches a predetermined position, the cylinder 54 is energized and the supply pipe 48 is connected to the joint 52.
The nozzle block 4 is displaced in the horizontal direction integrally with the nozzle block 4.
The fluid passage 46 of 2a and its tip engage with each other (Fig. 6,
■Reference). At the same time, the nozzle block 42a is sufficiently clamped and positioned by the engagement of the supply tube 48.

Next, the work clamp cylinder 58 and the work clamp cylinder 60 facing it are driven, and the work clamp cylinder 58 displaces the cylinder rod 58a in the horizontal direction, and engages the cylindrical body 66a with the cylindrical conduit 132C of the nozzle holding member 134c. At the same time, the sliding member 67a inside the cylindrical body 66a is fitted into the cylindrical conduit 132c. As a result, the nozzle holding member 134C is displaced relative to the workpiece W2 and clamps the workpiece W2. At the same time, the work clamp cylinder 60 is energized and the shaft 64b is displaced, and the sliding member 67b of the cylindrical body 66b presses the nozzle block 136b in the same manner as above, and firmly engages with the other side of the work W2. . That is, the workpiece W2 is clamped by the workpiece clamp cylinders 58 and 60 (see FIG. 6, ■). In this case, the gear 78 of the motor 74 is in mesh with the gear 70, but since the gear 70 slides on the spline 68 carved in the shaft 64b, the mesh between the gears 70 and 78 cannot be disengaged. do not have.

In the above configuration, if the cylinder 82 into which the fluid supply pipe 80 is inserted is driven to move horizontally, its tip block holder will fit into the cylindrical conduit 104c. If cleaning liquid is supplied from the fluid supply pipe 80, the cleaning liquid passes through the fluid supply pipe 80, enters the pipe line 104c, and reaches the passage 92c via the hole 108, as well as via the opening 94G, as shown by the arrow. and reaches the passage 110c. Since this passage 110c communicates with the cylindrical pipe line 132c, the cleaning liquid is sprayed onto the workpiece W2 from the nozzle blocks 136c and 136d. On the other hand, aisle 1
10C is connected to passages 116a and 116b. Therefore, the cleaning liquid reaches the passages 124b and 126a,
Nozzle blocks 130d and 130 communicating with the respective passages
The cleaning liquid is similarly poured onto the workpiece W2 from e. Moreover, the nozzle block 95 is connected to the passage 92c of the shaft 84.
Since the cleaning liquid is also poured into C, the supply pipe 8
From 0 onward, the cleaning liquid is supplied to the five sides of the workpiece W2 (see FIG. 6, ■). At the same time, cleaning liquid is also supplied from the fluid supply pipe 48 to the nozzle block 42a through the passage 46. This cleaning liquid is useful for removing cutting debris from the lower surface of the workpiece W2 (see FIG. 6, ■).

When the first cleaning step performed as described above is completed after a predetermined period of time has elapsed, the cylinder 26 is driven again and the cylinder rotor l'' 26a is lowered.

As a result, the nozzle block 42a and the workpiece W2 held therein integrally move downward to a predetermined position (sixth
(see figure, ■). During this time, the fluid supply pipe 80 is connected to the shaft 84.
The supply of cleaning fluid from is stopped.

Next, the cylinder 82 is energized and the fluid supply pipe 80 performs a clocking operation, and its tip end is connected to the nozzle block holder 1.
008 is released from the cylindrical pipe 104c. In the same way, the cylinder 54 also performs a clocking-out operation, and the supply pipe 48 separates from the nozzle block 42a.

Thereafter, the motor 88 is driven to rotate, thereby causing the shaft 84 and the nozzle block holder 1008.100 to
b rotates integrally. As a result, the next-stage nozzle blocks 130b and 130C occupy the lowest position. Next, the cylinder 26 is driven again and the workpiece W2 is raised. Therefore, the work clamp cylinders 58, 60 are energized again, and the sliding members 67 of the cylindrical bodies 55a, 66b are
a, 67b are the nozzle block holders 1008.1
00b is secured to the cylindrical bodies 102b, 102b, and the workpiece W2 is clamped.

In such a state, the cylinder 26 performs a closing operation (see FIG. 6, ■), and the workpiece W2 is eventually held in a hollow state while being clamped by the workpiece clamp cylinders 58 and 60. At this time, the fluid supply pipe 80 is connected to the pipe line 104b under the driving action of the cylinder 82, and then the fluid supply pipe 80 supplies the cleaning liquid into the shaft 84 again. Similarly to the above, the nozzle blocks 95b, 130b, 130C and 13 are applied to the workpiece W2 through the passage.
Cleaning liquid is supplied from 6C1136c, and the cleaning liquid is ejected from the side and upper end of the workpiece (see Fig. 6, ■).

Furthermore, the second part of the workpiece W2 cleaned by this
When the process is completed, the cylinder 26 is driven again and starts holding the workpiece W2. That is, the cylinder 26 is energized again to lower the workpiece to a predetermined position (
(See Figure 6, ■). Next, the motor 88 is driven to rotate, the shaft 84 is rotated, and the next nozzle block 95 a
, 130a, 130h, 136a, 136a, etc. occupy the lowest position. In this state, the cylinder 26
is energized and raises the τ workpiece W2 to a predetermined position (6th
(see figure, [phase]), then the work clamp cylinder 58

Air is now supplied from 0, and the nozzle blocks 95a>130a, 130h, 136a, 13
Air at a predetermined pressure is ejected from 6a and 42a to the workpiece W2, removing the cleaning fluid together with the cutting debris (see Fig. 6, ■@■.
g, 130f, 136d, and 136d to complete the four steps. Note that in the fourth step, air is not ejected from the nozzle block 42a (see 0 in FIG. 6).

When the cleaning process is completed as described above, the cylinder 26
As a result, the workpiece W2, together with the nozzle block 42a and the holding member 40a, moves into the hole 3 of the conveyance table 30a.
Take a seat at 6a. Therefore, by driving a conveying device (not shown) in the horizontal direction, the rollers 32a, 32 of the conveying table 30a can be moved.
a moves on the rail member 22 and reaches the delivery portion. During this period, the workpiece W held on the conveyor table 30b
1 reaches just above the cylinder 26 as described above.

On the other hand, when the cylinder 24 is driven, the clamp 24
The cylinder rod 24a raises the workpiece W2 to the outside of the casing 12 together with the nozzle pro-7ri 42, and takes it out via a transport device (not shown). During this time, the mist collector 140 is constantly energized to effectively discharge the cleaning liquid and the compressed air mist inside the casings 12 and 14.

According to the present invention, as described above, a plurality of nozzle blocks are attached to one cleaning device, and the nozzle block is rotatably held to supply cleaning liquid and cleaning air from various angles to the workpiece. can be provided. Therefore, the area occupied by the line of the cleaning device attached to the cutting device can be extremely reduced, and the rotating nozzle block can feed cleaning liquid and compressed air to the workpiece from various angles as described above. Therefore, there is no need to adjust the tip of the nozzle that sprays cleaning liquid or compressed air depending on the type of workpiece. Therefore, there is an advantage that the cleaning process can be accomplished in a very short time and efficiently. Furthermore, as shown in the seventh cabinet, a plurality of casings 14 are arranged side by side, whereby the respective steps include the first and second steps using the cleaning liquid, for example, performed on the casing A side, and If the process of blowing off the cleaning fluid and cutting debris using compressed air is performed all at once in a room, for example, even if one process takes 20 seconds, it will only take 40 seconds in each case. This has the advantage that the time interval can be halved compared to repeating the entire process with one cleaning device as in the above embodiment. Further, a housing 14 is provided for each of the first to fourth steps as shown in FIG. Step C and the fourth
By performing the following steps, each step can be performed in a 20 second cycle, and the cleaning step can be accomplished in a flow-wise manner.

As is clear from the above description, such variations have the effect of increasing time savings in the cleaning process.

Although the present invention has been described above with reference to preferred embodiments, the present invention is not limited to these embodiments (various improvements and design changes can be made without departing from the gist of the present invention). Of course there is.
