Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to a boring machine base and its operating method. Background Technology

[0002] In the shipbuilding industry, during the shipbuilding process, cylinder boring machines are mainly used for machining the connecting holes of intermediate shafts and main engine flywheels. The cylinder boring machine base is an important component of the cylinder boring machine connection. The cylinder boring machine base needs to have sufficient strength and rigidity to ensure the stability of the cylinder boring machine during the boring process.

[0003] In the existing technology, for each series of ship types, the shaft diameter of the intermediate shaft is provided before the new ship type is built. The usability of the boring machine base is determined by the shaft diameter of the intermediate shaft and the center distance of the holes to be machined. If the size and center height do not match, other boring machine bases need to be replaced, which has poor versatility, is time-consuming and increases economic costs. Summary of the Invention

[0004] The purpose of this invention is to provide a boring machine base and operating method to solve the problem that the boring machine base in the prior art cannot be adjusted, resulting in poor versatility.

[0005] On one hand, the present invention provides a boring machine base, which includes: an upper clamp; a lower clamp, detachably connected to the upper clamp and forming an installation area between them, the installation area allowing an intermediate shaft to pass through; a first adjusting member and a second adjusting member, the first adjusting member being adjustablely disposed on the inner wall of the upper clamp along the radial direction of the intermediate shaft and facing the installation area, the second adjusting member being adjustablely disposed on the inner wall of the lower clamp along the radial direction of the intermediate shaft and facing the installation area, both the first adjusting member and the second adjusting member being able to abut against the intermediate shaft to define the position of the intermediate shaft; and a fixed base, movably disposed on the upper clamp, the fixed base being capable of mounting the boring machine.

[0006] As an optional technical solution for the boring machine base, there are multiple first adjustment components, which are circumferentially spaced on the inner wall of the upper hoop.

[0007] As an optional technical solution for the boring machine base, the first adjusting component includes a first fastener and multiple adjusting blocks of different thicknesses. The multiple adjusting blocks of different thicknesses can be selectively connected to the inner wall of the upper hoop via the first fastener, and the adjusting blocks can abut against the intermediate shaft.

[0008] As an optional technical solution for the base of the cylinder boring machine, the adjusting block is made of copper.

[0011] As an optional technical solution for the base of the boring machine, the fixed seat includes a third adjusting member and a fixed seat body. The fixed seat body is connected to the upper hoop seat through the third adjusting member. The third adjusting member is vertically adjustable to adjust the distance between the fixed seat body and the upper hoop seat. The fixed seat body can be used to mount the boring machine.

[0012] As an optional technical solution for the boring machine base, the third adjusting component includes a third fastener and multiple pads of different thicknesses. The third fastener passes through the upper hoop, the pads, and the fixed seat body in sequence to connect the fixed seat body and the upper hoop.

[0037] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] like Figures 1 to 2As shown, this embodiment provides a boring machine base, which includes an upper clamp 1, a lower clamp 2, a first adjusting member 4, a second adjusting member 5, and a fixed base 6. The lower clamp 2 is detachably connected to the upper clamp 1, and a mounting area 3 is formed between them, allowing an intermediate shaft to pass through. The first adjusting member 4 is adjustablely positioned on the inner wall of the upper clamp 1 along the radial direction of the intermediate shaft, facing the mounting area 3. The second adjusting member 5 is adjustablely positioned on the inner wall of the lower clamp 2 along the radial direction of the intermediate shaft, also facing the mounting area 3. Both the first adjusting member 4 and the second adjusting member 5 can abut against the intermediate shaft to define its position. The fixed base 6 is vertically detachable from the upper clamp 1 and can mount the boring machine.

[0039] The boring machine base of this invention allows for the adjustment of the distance between the upper clamping seat 1 and the intermediate shaft using the first adjusting member 4, and the distance between the lower clamping seat 2 and the intermediate shaft using the second adjusting member 5, based on the shaft diameter of the central shaft and the center distance of the holes to be machined in the drawings. Furthermore, the fixed seat 6 is flexibly mounted on the upper clamping seat 1. This ensures compatibility with intermediate shafts of different diameters while also adjusting the distance between the boring machine and the upper clamping seat 1, further ensuring that the clearance between the boring machine's cutting edge and the machined hole is within a preset range, thereby achieving the machining of the hole. The boring machine base of this invention effectively solves the problem of poor versatility caused by the inability to adjust existing boring machine bases.

[0040] In some embodiments, multiple first adjusting members 4 are provided, and the multiple first adjusting members 4 are circumferentially spaced on the inner wall of the upper hoop 1. This arrangement can ensure the contact strength between the first adjusting members 4 and the intermediate shaft, and prevent the central shaft from shifting.

[0041] In this embodiment, the first adjusting member 4 includes a first fastener 41 and a plurality of adjusting blocks 42 of different thicknesses. The plurality of adjusting blocks 42 of different thicknesses can be selectively connected to the inner wall of the upper hoop 1 through the first fastener 41. This arrangement allows the thickness of the adjusting blocks 42 to be adjusted according to the actual situation, thereby adjusting the position of the adjusting blocks 42 in the radial direction along the intermediate axis, so that the adjusting blocks 42 can abut against the intermediate axis.

[0042] Furthermore, the material of the adjusting block 42 may include, but is not limited to, copper. By setting the material of the adjusting block 42 to copper, it will not damage the outer wall of the intermediate shaft when it comes into contact with it.

[0043] In some embodiments, the second adjusting member 5 includes a second fastener and a plurality of bushings 51 of different thicknesses. The plurality of bushings 51 of different thicknesses can be selectively connected to the inner wall of the lower clamp 2 via the second fastener. This configuration allows the thickness of the bushings 51 to be adjusted according to actual conditions, thereby adjusting the position of the bushings 51 in the radial direction along the intermediate axis, and the bushings 51 can abut against the intermediate axis.

[0044] Specifically, the shape of the bushing 51 matches the shape of the inner wall of the lower hoop 2. This arrangement allows it to fit the inner wall of the lower hoop 2, thereby abutting more tightly against the outer wall of the intermediate shaft.

[0045] Optionally, the bushing 51 is semi-circular in shape.

[0046] In this embodiment, the fixed base 6 includes a third adjusting member 61 and a fixed base body 62. The fixed base body 62 is connected to the upper clamping seat 1 via the third adjusting member 61. The third adjusting member 61 is vertically adjustable, allowing the distance between the fixed base body 62 and the upper clamping seat 1 to be adjusted according to actual conditions, thereby improving the machining of the machining hole. A boring machine can be mounted on the fixed base body 62.

[0047] Furthermore, the third adjusting member 61 includes a third fastener 611 and multiple pads 612 of different thicknesses. The third fastener 611 is passed sequentially through the upper clamp 1, the pads 612 and the fixing body 62, thereby connecting the fixing body 62 and the upper clamp 1. The multiple pads 612 of different thicknesses can be selectively set to adjust the distance between the fixing body 62 and the upper clamp 1.

[0048] In some embodiments, the mounting body 62 includes a mounting body 621 and a mounting cover 622. The mounting body 621 is connected to the upper clamp 1 via a third adjusting member 61, and the mounting cover 622 is connected to the mounting body 621 to fix the boring machine.

[0049] Optionally, there are two upper hoop seats 1 and two lower hoop seats 2. The two upper hoop seats 1 are connected by a connecting plate, and the two lower hoop seats 2 are connected to the two upper hoop seats 1 respectively.

[0050] This embodiment also provides an operation method for a boring machine base, applicable to a boring machine base including the above-described scheme. The operation method for the boring machine base includes: firstly, determining the shaft diameter of the intermediate shaft and the center distance of the hole to be machined; setting the upper clamp 1 on the intermediate shaft; adjusting the distance between the upper clamp 1 and the intermediate shaft using the first adjusting member 4; adjusting the distance between the fixed base body 62 and the upper clamp 1 using the third adjusting member 61 of the boring machine base; installing the boring machine on the fixed base 6, so that the gap between the boring machine's cutting edge and the hole to be machined is within a preset range; installing the lower clamp 2 on the upper clamp 1; adjusting the distance between the lower clamp 2 and the intermediate shaft using the second adjusting member 5, and again confirming that the gap between the boring machine's cutting edge and the hole to be machined is within a preset range; and machining the hole to be machined using the boring machine. The operating method of the boring machine base of the present invention allows for the adjustment of the distance between the upper clamping seat 1 and the intermediate shaft using the first adjusting member 4, and the distance between the lower clamping seat 2 and the intermediate shaft using the second adjusting member 5, based on the shaft diameter of the central shaft and the center distance of the hole to be machined in the drawing. Furthermore, the fixed seat 6 is flexibly mounted on the upper clamping seat 1. This ensures compatibility with intermediate shafts of different diameters while also adjusting the distance between the boring machine and the upper clamping seat 1, further ensuring that the clearance between the boring machine's cutting edge and the machined hole is within a preset range, thereby achieving the machining of the hole. The operating method of the boring machine base of the present invention effectively solves the problem of poor versatility caused by the inability to adjust the existing boring machine base.
