Referring to fig. 1 to 7, a process for manufacturing an endoscope channel mechanism according to an embodiment of the present invention includes the steps of: preparing, placing one end 210 of the conduit into the sleeve 100, and clamping and fixing the conduit 200 and the sleeve 100 on a machining device; the milling workpiece, the milling cutter and the sleeve 100 and the conduit 200 are moved towards each other, the conduit 200 and/or the sleeve 100 are milled, a chip ring 300 extends from one end 210 of the conduit and/or from the inner wall of the sleeve 100, and the chip ring 300 seals the gap between the sleeve 100 and the conduit 200.
In the preparatory step, one end 210 of the conduit is inserted into the sleeve 100 from the lower end of the sleeve 100 until the end face 211 of the conduit is in the vicinity of the insole 110 of the sleeve 100 and then fixed to the machining equipment — there are three possible cases: as shown in fig. 1, the end face 211 of the conduit is above the insole 110 of the sleeve 100; as shown in fig. 2, one end face 211 of the conduit is flush with the inner bottom 110 of the sleeve 100; as shown in fig. 3, one end face 211 of the conduit is below the insole 110 of the sleeve 100.
In the step of milling the workpiece, the milling cutter extends into the sleeve 100 from above the sleeve 100, the face of the milling cutter is opposite to one end face 211 of the guide pipe, the milling cutter moves downwards or the workpiece moves upwards or the milling cutter and the workpiece move towards each other at the same time, and during the process, the milling cutter mills the workpiece, material chips are generated, and the material chips are accumulated in the gap between the sleeve 100 and the guide pipe 200, so that an annular structure, namely a chip accumulation ring 300, is generated. In the step of milling the workpiece, there are three possible situations according to the specific milling position: milling only the conduit 200, chips of material will be generated from one end 210 of the conduit and extend to the inner wall of the sleeve 100, and the structure shown in fig. 4-6 can be formed; milling only the sleeve 100, chips of material will be generated from the inner wall of the sleeve 100 and extend onto the conduit 200, and the structure shown in fig. 7 can be formed; milling both the conduit 200 and the sleeve 100 simultaneously produces material chips at both the end 210 of the conduit and the inner wall of the sleeve 100 that extend into the inner wall of the sleeve 100 and the conduit 200, respectively, and can also be configured as shown in fig. 7.
Meanwhile, in the step of milling the workpiece, the material chips are naturally accumulated and filled in the gap between the sleeve 100 and the guide pipe 200, and the chip accumulation ring 300 is finally formed and the gap between the sleeve 100 and the guide pipe 200 is sealed through extrusion of the cutter, a hot melting effect on the material chips by heat generated by friction between the cutter and the workpiece in the machining process, and an extrusion effect generated by slight radial vibration generated by the fact that the cutter collides with the guide pipe 200 in the machining process. It will be appreciated that if the material of the milled workpiece is relatively ductile, some deformation of the milled workpiece may also become part of the chip ring 300 during the milling process.
It will be appreciated that there is no strict requirement on the profile of the sleeve 100 and the shape of the channel inside the conduit 200. In the structure shown in fig. 1, only a small circular through hole is required to be formed in the sleeve 100 to accommodate the catheter 200, and the small circular through hole and an external large channel are required to be communicated with the inside of the sleeve 100 to facilitate the tool to extend into the sleeve 100 for processing, and the sleeve 100 may have various shapes such as a cylinder, a cuboid, a cone and the like; the part of the conduit 200 which only needs to extend into the sleeve 100 is cylindrical, the gap between the conduit 200 and the sleeve 100 is not too large, the cutter can conveniently process the accumulated chip ring 300 for sealing, no requirement is made on whether a channel in the conduit 200 is a circular hole, and no requirement is made on the appearance of the part of the conduit 200 which does not extend into the sleeve 100. In the structure shown in fig. 2 and 3, the upper end of the insole 110 of the sleeve 100 may be omitted, and only a base having a circular through hole may be used as the sleeve 100 of the present invention.
Referring to fig. 1, 4 and 5, in some embodiments of the invention, in the preparation step, one end 210 of the conduit is placed into the sleeve 100 with one end face 211 of the conduit above the insole 110 of the sleeve 100, and in the step of milling the workpiece, the portion of the conduit 200 protruding out of the insole 110 of the sleeve 100 is milled, either fully or partially, with the debris ring 300 extending out of the end 210 of the conduit, sealing the gap between the sleeve 100 and the conduit 200.
As shown in fig. 1, in the preparation step, one end 210 of the guide tube is inserted into the sleeve 100 from the lower end of the sleeve 100 until the end face 211 of the guide tube is above the insole 110 of the sleeve 100, and then fixed to the machining apparatus. In the step of milling the workpiece, the milling cutter extends into the sleeve 100 from above the sleeve 100, the face of the milling cutter is opposite to one end face 211 of the conduit, the milling cutter moves downwards or the workpiece moves upwards or the milling cutter and the workpiece move towards each other at the same time, in the process, the milling cutter 200 of the cutter generates material chips which are generated by one end 210 of the conduit and extend to the inner wall of the sleeve 100, and the material chips are accumulated in a gap between the sleeve 100 and the conduit 200 to generate an annular structure which is called a chip accumulation ring 300. The milling cutter will eventually stop at a position above the bottom 110 of the sleeve 100, ending the step of milling the workpiece, resulting in the configuration shown in fig. 4. Only milling the conduit 200 and not milling the sleeve 100 has no damage to the sleeve 100, and only milling a part of the conduit 200 above the inner bottom 110 of the sleeve 100 has high fault tolerance rate in the machining process, small precision requirement, larger selectable size range of the cutter and convenient machining.
As shown in fig. 1, in the preparation step, one end 210 of the guide tube is inserted into the sleeve 100 from the lower end of the sleeve 100 until the end face 211 of the guide tube is above the insole 110 of the sleeve 100, and then fixed to the machining apparatus. In the step of milling the workpiece, the milling cutter extends into the sleeve 100 from above the sleeve 100, the face of the milling cutter is opposite to one end face 211 of the guide pipe, the milling cutter moves downwards or the workpiece moves upwards or the milling cutter and the workpiece move towards each other at the same time, in the process, the milling cutter 200 of the cutter generates material chips which are generated by one end 210 of the guide pipe and extend to the inner wall of the sleeve 100, and the material chips are accumulated in a gap between the sleeve 100 and the guide pipe 200 to generate an annular structure which is called a chip accumulation ring 300. The milling cutter will eventually stop at the location of the bottom 110 of the sleeve 100, ending the step of milling the workpiece, resulting in the configuration shown in fig. 5. Only the guide pipe 200 is milled, the sleeve 100 is not milled, the damage to the sleeve 100 is not damaged, only the part of the guide pipe 200 above the inner bottom 110 of the sleeve 100 is milled, the fault tolerance rate in the machining process is high, the precision requirement is low, the machining is convenient, when the position of the inner bottom 110 of the sleeve 100 is machined, more material chips are generated, and the gap between the sleeve 100 and the guide pipe 200 is small, so that the sealing effect of the chip accumulation ring 300 is better.
Referring to fig. 1 and 6, in some embodiments of the invention, in a preparatory step, one end 210 of the conduit is placed into the sleeve 100 with one end face 211 of the conduit above the insole 110 of the sleeve 100, and in a milling work step, the portion of the conduit 200 protruding out of the insole 110 of the sleeve 100 is milled in whole or in part, and the conduit 200 is further milled down until the one end face 211 of the conduit is below the insole 110 of the sleeve 100, with the debris ring 300 extending out of the one end 210 of the conduit, sealing the gap between the sleeve 100 and the conduit 200.
As shown in fig. 1, in the preparation step, one end 210 of the guide tube is inserted into the sleeve 100 from the lower end of the sleeve 100 until the end face 211 of the guide tube is above the insole 110 of the sleeve 100, and then fixed to the machining apparatus. In the step of milling the workpiece, the milling cutter extends into the sleeve 100 from above the sleeve 100, the face of the milling cutter is opposite to one end face 211 of the conduit, the milling cutter moves downwards or the workpiece moves upwards or the milling cutter and the workpiece move towards each other at the same time, in the process, the milling cutter 200 of the cutter generates material chips which are generated by one end 210 of the conduit and extend to the inner wall of the sleeve 100, and the material chips are accumulated in a gap between the sleeve 100 and the conduit 200 to generate an annular structure which is called a chip accumulation ring 300. The milling cutter will eventually stop at a position below the bottom 110 of the sleeve 100, ending the step of milling the workpiece, resulting in the configuration shown in fig. 6. Only the guide tube 200 is milled without milling the sleeve 100, the sleeve 100 has no damage, the milling cutter is required to be deep under the insole 110 of the sleeve 100, the size requirement of the milling cutter is stricter, but the milling cutter is only required to be machined under the insole 110 of the sleeve 100, the requirement on machining precision is lower, the machining is convenient, more material chips are generated in the machining process, the gap between the sleeve 100 and the guide tube 200 is smaller, and when the milling cutter is machined under the insole 110 of the sleeve 100, more material chips are generated, the gap between the sleeve 100 and the guide tube 200 is smaller, so that the sealing effect of the chip collecting ring 300 is better.
Referring to fig. 1 and 7, in some embodiments of the invention, in the preparation step, one end 210 of the conduit is placed into the sleeve 100 with one end face 211 of the conduit above the insole 110 of the sleeve 100, and in the step of milling the workpiece, the conduit 200 is milled to protrude out of the entire portion of the insole 110 of the sleeve 100, and further the portion of the conduit 200 not protruding out of the insole 110 of the sleeve 100 and a portion of the inner wall of the sleeve 100 are milled down, so that the debris ring 300 extends out from the one end 210 of the conduit and the inner wall of the sleeve 100, sealing the gap between the sleeve 100 and the conduit 200.
As shown in fig. 1, in the preparation step, one end 210 of the guide tube is inserted into the sleeve 100 from the lower end of the sleeve 100 until the end face 211 of the guide tube is above the insole 110 of the sleeve 100, and then fixed to the machining apparatus. In the step of milling the workpiece, the milling cutter extends into the sleeve 100 from above the sleeve 100, the face of the milling cutter is opposite to one end face 211 of the conduit, the milling cutter moves downwards or the workpiece moves upwards or the milling cutter and the workpiece move towards each other at the same time, in the process, the milling cutter of the sleeve 100 and the conduit 200 can generate material chips, the material chips can be generated by the inner wall of the sleeve 100 and one end 210 of the conduit and extend to one end 210 of the conduit and the inner wall of the sleeve 100 respectively, and the material chips are accumulated in a gap between the sleeve 100 and the conduit 200 to generate an annular structure which is called a chip accumulation ring 300. The milling cutter will eventually stop at a position below the bottom 110 of the sleeve 100, ending the step of milling the workpiece, resulting in the configuration shown in fig. 7. The sleeve 100 and the conduit 200 are milled simultaneously, which is beneficial to extruding and heating the material chips in the gap between the sleeve 100 and the conduit 200, so that the formed chip-accumulating ring 300 has better sealing performance.
Referring to fig. 3 and 6, in some embodiments of the invention, in a preparatory step, one end 210 of the conduit is placed into the sleeve 100 with one end face 211 of the conduit below the insole 110 of the sleeve 100, and one end 210 of the conduit is milled to extend the debris ring 300 out of the one end 210 of the conduit, sealing the gap between the sleeve 100 and the conduit 200.
As shown in fig. 3, in the preparation step, one end 210 of the guide tube is inserted into the sleeve 100 from the lower end of the sleeve 100 until one end face 211 of the guide tube is positioned below the insole 110 of the sleeve 100, and then fixed to the machining apparatus. In the step of milling the workpiece, the milling cutter extends into the sleeve 100 from above the sleeve 100, the face of the milling cutter is opposite to one end face 211 of the conduit, the milling cutter moves downwards or the workpiece moves upwards or the milling cutter and the workpiece move towards each other at the same time, in the process, the milling cutter 200 of the cutter generates material chips which are generated by one end 210 of the conduit and extend to the inner wall of the sleeve 100, and the material chips are accumulated in a gap between the sleeve 100 and the conduit 200 to generate an annular structure which is called a chip accumulation ring 300. The milling cutter will eventually stop at a position below the bottom 110 of the sleeve 100, ending the step of milling the workpiece, resulting in the configuration shown in fig. 6. Milling only the conduit 200 and not the sleeve 100 does not damage the sleeve 100, the size requirements for the milling cutter are more stringent since the milling cutter is required to be deep below the bottom 110 of the sleeve 100, and fewer conduits 200 are shaved off during the machining process, which reduces machining time and saves material.
Referring to fig. 3 and 7, in some embodiments of the present invention, in the preparation step, one end 210 of the conduit is placed into the sleeve 100 such that one end face 211 of the conduit is located below the insole 110 of the sleeve 100, the inner wall of the sleeve 100 is milled, and the debris ring 300 is extended from the inner wall of the sleeve 100, sealing the gap between the sleeve 100 and the conduit 200.
As shown in fig. 3, in the preparation step, one end 210 of the guide tube is inserted into the sleeve 100 from the lower end of the sleeve 100 until one end face 211 of the guide tube is positioned below the insole 110 of the sleeve 100, and then fixed to the machining apparatus. In the step of milling the workpiece, the milling cutter extends into the sleeve 100 from above the sleeve 100, the face of the milling cutter is opposite to one end face 211 of the conduit, the milling cutter moves downwards or the workpiece moves upwards or the milling cutter and the workpiece move towards each other at the same time, in the process, the milling cutter of the sleeve 100 generates material chips, the material chips are generated by the inner wall of the sleeve 100 and extend to one end 210 of the conduit, and the material chips are accumulated in the gap between the sleeve 100 and the conduit 200 to generate an annular structure which is called a chip accumulation ring 300. The milling cutter will eventually stop at a position below the bottom 110 of the sleeve 100 and above the end face 211 of the conduit, ending the step of milling the workpiece, resulting in the configuration shown in fig. 7. Only the sleeve 100 is milled and the guide pipe 200 is not milled, the damage to the guide pipe 200 is not damaged, the size requirement of the milling cutter is looser due to the requirement of milling the sleeve 100, and the size selectable range of the cutter is larger.
Referring to fig. 3 and 7, in some embodiments of the present invention, a seal filling step is further included, and a sealing medium 400 is further filled in the gap between the sleeve 100 and the conduit 200.
Since the chip ring 300 is located at the end 210 of the conduit, and a larger clearance space is generally left between the sleeve 100 and the conduit 200 below the chip ring 300, the sealing medium 400 can be filled therein to perform a sealing filling step, thereby further increasing the sealing performance of the channel mechanism. It can be understood that, in the process of forming the chip ring 300 by machining, the collision between the cutter and the conduit 200 causes the conduit 200 to generate vibration and heat generated in the machining process has a certain influence on the sealing medium 400 which may exist, and this influence behavior can be regarded as that a very large stirring rod is arranged in a beaker to stir liquid in the beaker, and the beaker is heated, the beaker is the sleeve 100, the stirring rod is the conduit 200, the liquid is the sealing medium 400, the stirring behavior is that the collision between the cutter and the conduit 200 causes the conduit 200 to generate vibration, and the heating behavior is that the cutter mills the workpiece to generate heat. Therefore, before the step of milling the workpiece, a sealing and filling step can be performed, so that the sealing medium 400 generates a certain hot melting and softening effect due to the above-mentioned influence action, and is distributed more uniformly and tightly due to the stirring effect, and the sealing effect is better.
Referring to fig. 1-7, in some embodiments of the invention, the sleeve 100 and/or conduit 200 material is steel.
The material of the chip accumulation ring 300 is the same as that of a milled workpiece, namely the material of the sleeve 100 or the conduit 200, so that the material of the chip accumulation ring 300 depends on the material of the sleeve 100 or the conduit 200, and the sleeve 100 or the conduit 200 is made of 316L stainless steel in steel, and the 316L stainless steel has the advantages of good corrosion resistance, high ductility and the like, so that the formed chip accumulation ring 300 can better meet the sealing requirement, and the 316L stainless steel is selected to meet the use requirement because the endoscope relates to a human body. It can be understood that when the melting point of the material is low, the dust ring 300 is more easily transformed into a hot melt state by the heat generated during the process, and thus the sealing effect is better. It can also be understood that when the toughness of the material is better, the chip-collecting ring 300 is pressed by the cutter to fill the gap between the conduit 200 and the sleeve 100, and the sealing performance is better; meanwhile, if the material toughness of the milled workpiece is good, the milled workpiece can generate certain deformation in the milling process and also become a part of the chip accumulation ring 300, so that the sealing performance of the chip accumulation ring 300 is improved.
Referring to fig. 1-7, in some embodiments of the invention, the swarf ring 300 is fusion bonded to the conduit 200 and sleeve 100 during the step of milling the workpiece.
In the step of milling the workpiece, a certain amount of heat is generated by the friction between the milling cutter and the workpiece, and the workpiece and the material chips are heated. When the melting point of the material is reached, the material chips become molten and are melted and combined with the conduit 200 and the sleeve 100 to form the chip ring 300, and the sealing effect is excellent.
Referring to fig. 1-7, in some embodiments of the invention, the mill diameter is larger than the outer diameter of the guide tube 200 and smaller than the inner diameter of the sleeve 100.
When only the guide tube 200 needs to be milled, the milling cutter is larger in diameter than the outer diameter of the guide tube 200 and smaller than the inner diameter of the sleeve 100. It will be appreciated that the sleeve 100 and guide tube 200 are milled to the condition shown in figures 4 and 5, the milling cutter having a diameter greater than the outer diameter of the guide tube 200 and less than the inner diameter of the sleeve 100, and in this case the difference between the inner diameter of the sleeve 100 and the outer diameter of the guide tube 200 is greater, and therefore the range of optional sizes of the milling cutter is greater; it is necessary to mill the sleeve 100 and the guide tube 200 into the state shown in fig. 6, the diameter of the milling cutter is larger than the outer diameter of the guide tube 200 and smaller than the inner diameter of the sleeve 100, and the difference between the inner diameter of the sleeve 100 and the outer diameter of the guide tube 200 is smaller at this time, so the optional size range of the milling cutter is smaller; it is necessary to mill the sleeve 100 and the guide tube 200 into the state shown in fig. 7, in which the diameter of the milling cutter is larger than both the outer diameter of the guide tube 200 and the inner diameter of the sleeve 100, and in which case the optional size range of the milling cutter is larger.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
