The slide base 9 is reciprocated linearly in the directions A and B along the slide rail 9a shown in FIG. The slide base 9 and the slide base moving cylinder 10 are fixed on a table 11 having moving wheels. The table 11 is provided with a supply / discharge device 14 for switching between supply and suction of a liquid such as a cleaning liquid or compressed air in the drive shaft 4 and the cleaning shaft 1, and is attached to an end of the drive shaft 4 by a hose 12. A cleaning liquid and compressed air are supplied into the drive shaft 4 and the cleaning shaft 1 through the joint 13.

FIG. 3 is an enlarged sectional view showing the cleaning shaft 1. As shown in FIG. 1 is a cleaning shaft, 2 is a brush provided on the surface of the cleaning shaft 1, and 18 is a hole penetrating inside and outside the cleaning shaft 1. The brush 2 extends in the axial direction of the cleaning shaft 1 and is divided into a plurality in the circumferential direction. FIG. 5 shows the configuration of the cleaning shaft 1 and the brush 2 when viewed from the front. In the first embodiment, a plurality of holes 18 penetrating the inside and outside of the cleaning shaft 1 are provided in the axial direction and the circumferential direction (the circumferential direction is not shown), and a plurality of holes 18 provided in the axial direction. The brush 2 is provided between 18.

Next, the operation of the apparatus for cleaning the inner surface of a pipe according to the first embodiment will be described. The bushing 15 to be cleaned is fixed to the bushing fixing base 17, and the movable table 11 having wheels is moved to the front of the bushing 15. On the table 11, a slide base 9 having a drive shaft rotating motor 8, a drive shaft 4, and the like, a slide base moving cylinder 10 for reciprocating the slide base 9 in a linear motion, and a cylinder rod 10a are mounted. After connecting one end of the cleaning shaft 1 to one end of the drive shaft 4, the other end of the cleaning shaft 1 is inserted into the conduit 16 of the bushing 15. Thereafter, the table 11 is fixed at a predetermined position.

When the apparatus is started in this state, the torque of the drive shaft rotating motor 8 is transmitted to the drive shaft 4 via the drive belt 8a, and the cleaning shaft 1 connected to the drive shaft 4 is placed in the conduit 16 of the bushing 15. The brush 2 provided on the cleaning shaft 1 and in contact with the conduit 16 of the bushing 15 cleans the solder particles and dust in the conduit 16 of the bushing 15. The pipe 16 of the bushing 15 is made of copper and is easily oxidized, but since the brush 2 is made of metal, the oxide film on the surface of the pipe 16 can be thinly removed and the inner surface of the oxidized pipe 16 can be cleaned. Can also.

The slide base moving cylinder 10
Is activated, the cleaning shaft 1 reciprocates linearly at the same time as the rotational movement, and the pipe 1 of the bushing 15

By operating the drive shaft rotation motor 8 and the slide base moving cylinder 10, the cleaning shaft 1 is cleaned as necessary, such as only the rotary motion, only the reciprocal linear motion, or both the rotary motion and the reciprocal linear motion. Can be changed, and various cleaning methods can be realized.

When the dirt in the bushing line 16 is severe, the supply / discharge device 14 can be activated to spray a liquid such as a cleaning liquid into the line 16 of the bushing 15. By operating the switching valves 14a and 14b, compressed air is blown in place of the liquid to blow off shavings, dust, solder particles, and the like on the surface of the conduit 16 which are removed by the brush 2 attached to the surface of the conduit 16. Can also. Efficiency is that the cleaning shaft 1 is made to reciprocate linearly while rotating, and the oxide film and solder particles on the surface of the conduit 16 of the bushing 15 are scraped off, blown with compressed air to float dirt, and then cleaned with a brush. It is a target. Further, after the cleaning liquid is first sprayed into the conduit 16 of the bushing 15 and then cleaned with a brush, the generation of excess dust can be minimized, and a comfortable working environment can be realized.

The supply / discharge device 14 supplies a liquid such as a cleaning liquid or a gas such as compressed air to the inside of the cleaning shaft 1, and a bushing 15 through a hole 18 passing through the inside and outside of the cleaning shaft 1.
In addition to spraying a liquid or gas to the pipeline 16, it also has a function of sucking shavings, solder particles, dust, and a cleaning liquid sprayed by the brush 2. Cleaning shaft 1
When the brush 2 is rotated or reciprocated linearly and suctioned while cleaning the inside of the conduit 16 of the bushing 15, shavings, such as solder debris and dust, obtained by the brush 2 shaving off the surface of the conduit 16, cause the brush 2 to pass through the conduit 16 It is sucked into the cleaning shaft 1 at the same time as cleaning, so that the working environment can be kept clean while cleaning efficiently.

In the first embodiment of the present invention, the cleaning shaft 1 provided with the brush 2 which extends in the axial direction of the cleaning shaft 1 and is divided into a plurality of parts in the circumferential direction is used. However, if necessary, a cleaning shaft provided with a spirally wound brush 2 or a cleaning shaft provided with a plurality of brushes 2 wound in the circumferential direction and divided in the axial direction. You may change it. When the cleaning shaft in which the brush 2 is spirally wound is used, the cylinder 10 for moving the slide base is used.
Even if the cleaning shaft is not activated, simply changing the rotation direction of the drive shaft rotation motor can provide the same effect as the linear movement of the cleaning shaft. The use of a cleaning shaft in which the brush 2 is wound in the circumferential direction and divided into a plurality of pieces in the axial direction can particularly remove dirt in the circumferential direction of the conduit 16 of the bushing 15. Of these three types of brushes, the effect on cleaning is particularly remarkable when a spirally wound brush is used.

Embodiment 2 In the first embodiment, a relatively small bushing is targeted for cleaning. Embodiment 2
Now, a case where a larger bushing is to be cleaned will be described. The configuration of the pipeline inner surface cleaning device according to the first embodiment and the configuration of the pipeline inner surface cleaning device according to the second embodiment may be basically the same. However, if the object to be cleaned becomes longer, some problems arise.

The first problem is the rigidity of the cleaning shaft. In the present invention, the cleaning is performed after the cleaning shaft is inserted through the bushing. However, when the cleaning target is long, there is a problem that the cleaning shaft cannot be inserted into the pipe if the rigidity of the cleaning shaft is insufficient. Further, even if the cleaning shaft can be inserted, there is a problem that the object to be cleaned becomes long, and accordingly, the longer the cleaning shaft, the more torque is required to rotate the cleaning shaft.

Further, even if the drive shaft rotating motor can generate enough torque to rotate the cleaning shaft, a reciprocating linear drive device having a stronger output and a stronger reciprocating linear drive device for making the cleaning shaft reciprocate linearly move. A mechanism for more securely fixing the table on which the device is mounted is required. Further, if the rigidity of the cleaning shaft is not sufficient, the cleaning shaft may be bent or twisted in the pipeline, and the cleaning in the pipeline may not be sufficiently performed.

In the second embodiment, the above-described problems are solved, and measures are taken for the cleaning of the inner surface of the pipeline described in the first embodiment so that even a long cleaning object can be efficiently cleaned. Things. As a countermeasure, there are a motor that generates a strong torque and a cleaning shaft formed of a material having high rigidity, but these are not features of the present invention.
In the second embodiment, the problem of the rigidity of the cleaning shaft can be solved by mounting the guide roller 19 on the cleaning shaft 1 provided with the brush 2 as shown in FIGS.

FIG. 4 shows a cleaning shaft according to the second embodiment. 1 is a cleaning shaft, 2 is a brush that extends in the axial direction of the cleaning shaft 1, is divided in the circumferential direction, and is provided with a plurality of brushes in the axial direction. 3 is a cleaning shaft end flange that connects the cleaning shaft 1 to the drive shaft. A drive shaft is not shown), and 19 is a guide roller fitted with a margin to a cleaning shaft between a plurality of brushes 2 provided in the axial direction.

FIG. 5 is a front view showing a cleaning shaft according to the second embodiment. 1a is the inside diameter of the cleaning shaft, 1b is the outside diameter including the brush 2, 19 is the guide roller, 19a is the inside diameter of the guide roller, and 19b is the outside diameter of the guide roller. The inner diameter 19a of the guide roller 19 is larger than the inner diameter 1a of the cleaning shaft,
The state where the guide roller 19 is loosely fitted to the cleaning shaft 1 is shown.

The cleaning shaft of the pipe inner surface cleaning device described in the first embodiment is replaced with the cleaning shaft 1 according to the second embodiment.
It is inserted into the conduit 16 of the bushing 15 to be cleaned.
Since the bushing 15 as the cleaning object of the second embodiment is longer than the bushing 15 of the first embodiment, the bushing 15 cannot be inserted into the conduit 16 if the rigidity of the cleaning shaft 1 is low. Therefore, the guide roller 19 loosely fitted on the cleaning shaft 1 reinforces the rigidity of the cleaning shaft and plays a role of facilitating the insertion of the cleaning shaft 1 into the conduit 16.

Since the guide roller 19 is loosely fitted to the cleaning shaft 1, the cleaning shaft 1 is prevented from bending due to frictional resistance of the brush 2 of the cleaning shaft 1 from the pipe line 16, and the cleaning shaft 1 is connected to the cleaning shaft 1. It serves to reduce the resistance of the road and assist the smooth insertion of the cleaning shaft 1. Further, in order to prevent a situation in which the brush 2 is bent due to friction between the inner diameter of the pipe and the brush 2 and the inner surface of the pipe is not sufficiently cleaned, the guide roller 19 reinforces the rigidity of the brush, so-called "strain". I have.

Embodiment 3 As described in Embodiments 1 and 2, the present invention is a pipe line inner surface cleaning device invented for cleaning the inside of a pipe line of a bushing.
