Description

  The present invention relates to an industrial endoscope apparatus capable of performing a treatment such as grinding with a rotating treatment member.

  2. Description of the Related Art Conventionally, an industrial endoscope is used for inspection of whether or not there is a failure or malfunction by being inserted into an industrial plant or jet engine, for example.

Such an industrial endoscope, for example, when a damage such as chipping or the like is found in various parts by endoscopic inspection in Patent Document 1, a grindstone can be used without disassembling the plant equipment or disassembling the engine. Disclosed is one that can be disposed at the tip and can rotate the grindstone to polish the parts.
Japanese Patent Laid-Open No. 9-120032

  However, an industrial endoscope may be used for inspecting burrs and the like generated in a metal product or a metal pipe that cannot be reached at the time of manufacture, and removing the generated burrs.

  Therefore, even if the grindstone can come into contact with a burr or the like, the industrial endoscope can only be partially polished and cannot be polished over a wide range. As a result, the user must rotate the guide tube and change the position of the grindstone many times depending on the position, state, etc. of the burr and the like. there were.

  Therefore, the present invention has been made in view of the above-described circumstances, and it is an object of the present invention to provide an industrial endoscope apparatus that can easily perform an inspection operation with polishing or the like regardless of the position, state, etc. of the treatment target portion.

  The cylindrical body 32 has a hole diameter slightly smaller than the outer diameter of the distal end portion of the tubular member 3 and is fixed to the outer peripheral portion of the distal end of the tubular member 3 by pressure bonding. Even in this configuration, when the polishing function of the polishing portion 33 is lowered, the cylindrical portion 32 is detachable from the distal end portion of the tubular member 3, so that the polishing portion 33 can be easily replaced.

  Moreover, the tubular member 3 may have a brush-like polishing portion 33 provided with a plurality of wires each having one end fixed in the circumferential direction to the outer peripheral portion of the tip as shown in FIG. In this configuration, as shown in FIG. 10, the polishing portion 33 is expanded in the outer peripheral direction by the rotation of the tubular member 3, and thus a wide polishing region can be secured.

  9 and 10, the plurality of wires constituting the brush-like polishing portion 33 are fixed to the outer peripheral portion of the tubular member 3 at the distal end side. You may make it adhere to an outer peripheral part.

  Furthermore, as shown in FIG. 11, the tubular member 3 includes a polishing portion (here, the polishing portion 6 of the present embodiment is illustrated, but of course also applies to each of the polishing portions 34 to 33 showing the above-described modifications.

A motor shaft 77 of a motor 80 disposed in the operation unit 4 is connected to the center of the base end surface of the circuit unit 73. The motor 80 is fixed by a slide base 78 and a fixing bracket 79 in the operation unit 4.

  The slide table 78 is fitted to the stage 81 so as to freely advance and retract. The slide table 78 moves forward and backward with respect to the stage 81 by a slide mechanism (not shown). This slide mechanism may be a helical gear train using a motor, or may be configured to advance and retract the slide table 78 by a solenoid, a manual lever by a user, or the like.

  The endoscope 1 d of the present embodiment configured as described above has the distal end portion 70 via the motor shaft 77, the circuit portion 73, and the shaft 72 as the slide base 78 advances and retreats with respect to the stage 81. Can be advanced and retracted to extend from the distal end portion of the tubular member 3 or be accommodated in the distal end portion.

  The endoscope 1 d can rotate the distal end portion 70 extending from the tubular member 3 by the motor 80 via the motor shaft 77, the circuit portion 73, and the shaft 72. Thereby, since the grinding | polishing part 71 of the front-end | tip part 70 also rotates, the user can grind and remove the burr | flash 100 etc. which generate | occur | produce frequently at the time of a lathe process.

  At this time, the user can easily come into contact with the portion to be treated (such as a burr) by bending the bending portion of the endoscope 1d. Further, the user can perform polishing over a wide range because the polishing portion 71 has a polishing area of the entire outer peripheral surface of the tip portion 70.

  As described above, the industrial endoscope apparatuses 1 to 1d described in each embodiment perform the polishing process on the object to be polished (such as burrs) discovered by the endoscopy, regardless of the position, state, and the like. Since it can be easily performed and polishing work can be performed in a wide range, the work efficiency is improved.

  In the present embodiment, the endoscope 1 having the above-described configuration is taken as an example, but the present invention can be applied to various rigid endoscopes as a matter of course. Moreover, the structure of each said grinding | polishing part should just be a thing which can grind | polish a metal etc., For example, it is set as various structures, such as a sand paper, a grindstone, a scissors, and a grinding | polishing brush, and is specifically limited to the above-mentioned embodiment. There is nothing.

  The invention described above is not limited to the present embodiment, and various modifications can be made without departing from the scope of the invention at the stage of implementation. Furthermore, the present embodiment includes various stages of the invention, and various inventions can be extracted by appropriately combining a plurality of disclosed constituent elements.

  For example, even if some constituent elements are deleted from all the constituent elements shown in this embodiment, the problems described in the column of problems to be solved by the invention can be solved, and the effects described in the effect of the invention Can be obtained as an invention.
