Description

Technical Field

[0001] This utility model belongs to the field of sloping disc runway processing tools, and particularly relates to a roughing and finishing runway processing cutter head. Background Technology

[0002] like Figure 4 and Figure 5 As shown, the housing of the through-shaft pump / motor has a swashplate track. The diameter of the swashplate track needs to be precisely matched with the diameter of the swashplate, which requires high machining precision. The current machining scheme requires the use of two angle heads for roughing and finishing respectively. For equipment that cannot automatically change angle heads, the machining process needs to be carried out step by step, with repeated clamping, which can easily lead to loss of accuracy. On the other hand, using equipment that can automatically change angle heads is expensive and can easily cause production bottlenecks. Regardless of which type of equipment is used, the angle head needs to be changed, resulting in low machining efficiency and poor machining quality stability. Utility Model Content

[0003] The purpose of this invention is to provide an integrated roughing and finishing cutter head for runway machining. This invention has the advantages of high machining efficiency and good machining quality stability.

[0004] The technical solution of this utility model is: a roughing and finishing integrated runway machining cutter head, including a disc-shaped base, with a roughing tool and a finishing tool arranged on the radial outer side of the base. The distance between the tip of the roughing tool and the axis of the base is smaller than the distance between the tip of the finishing tool and the axis of the base. In the axial forward direction of the base, the tip of the roughing tool is located in front of the tip of the finishing tool.

[0005] In the aforementioned integrated roughing and finishing runway machining cutter head, there are two roughing tools, which are symmetrically distributed about the axis of the base body.

[0006] In the aforementioned integrated roughing and finishing runway machining cutter head, planar notches are provided on both radial sides of the base, and the finishing tool is fixed to one of the planar notches.

[0007] In the aforementioned integrated roughing and finishing runway machining cutter head, V-shaped notches are provided on both radial sides of the substrate. One sidewall of the V-shaped notch is connected to the corresponding planar notch, and the other sidewall of the V-shaped notch is connected to the outer peripheral surface of the substrate. The roughing tool is located at the connection between the V-shaped notch and the outer peripheral surface of the substrate.

[0008] In the aforementioned integrated roughing and finishing cutter head for runway machining, the included angle of the V-shaped notch is between 100-120°, and the sidewall of the V-shaped notch connecting the outer peripheral surface of the substrate is located on the same plane as the axis of the substrate.

[0009] In the aforementioned integrated roughing and finishing runway machining cutterhead, the finishing tool is connected to the base through an adjustment mechanism, which makes the radial position of the finishing tool on the base adjustable.

[0010] In the aforementioned integrated roughing and finishing runway machining cutter head, the axial rear end of the base is provided with an installation structure for connecting runway machining equipment.

[0011] Compared with existing technologies, this invention features both a roughing tool and a finishing tool. In the axial direction, the roughing tool is positioned in front of the finishing tool. As the cutter head advances axially, the roughing tool first contacts the corresponding position on the swashplate track of the outer shell, removing most of the machining allowance. The finishing tool then follows, removing the remaining machining allowance. Roughing and finishing are completed simultaneously, resulting in higher machining efficiency. Because roughing and finishing are completed concurrently, only one angle head is needed during machining, reducing positioning errors caused by changing angle heads and thus improving machining quality stability. Therefore, this invention offers the advantages of high machining efficiency and good machining quality stability.

[0012] Furthermore, by incorporating notches, chip removal during machining is facilitated, reducing scratches on the machined surface and further improving machining quality stability. The position of the finishing tool is adjustable; after wear, tool wear can be compensated for by adjusting the position, ensuring qualified machining accuracy while reducing finishing tool consumption and lowering machining costs.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0020] Example: Integrated roughing and finishing cutter head for runway machining, such as Figure 1 As shown, it includes a disc-shaped base 1, with two roughing tools 2 and one finishing tool 3 arranged on the radial outer side of the base 1. The two roughing tools 2 are symmetrically distributed about the axis of the base 1.

[0021] The distance RC between the tip of the roughing tool 2 and the axis of the base 1 is less than the distance RJ between the tip of the finishing tool 3 and the axis of the base 1. In the axial advancing direction of the base 1, the tip of the roughing tool 2 is located in front of the tip of the finishing tool 3. The distance (H1, H2) between the tips of the roughing tool 2 and the finishing tool 3 in the axial direction of the base 1 should not be less than 0.1 mm, and 0.1-0.2 mm is more suitable.

[0022] The base 1 has planar notches 4 on both radial sides, and the finishing tool 3 is fixed to one of the planar notches 4. The other two radial sides of the base 1 have V-shaped notches 5, with an included angle between 100-120°. One sidewall of the V-shaped notch 5 connects to the corresponding planar notch 4, and the other sidewall connects to the outer circumferential surface of the base 1 and is located in the same plane as the axis of the base 1. The roughing tool 2 is positioned at the connection between the V-shaped notch 5 and the outer circumferential surface of the base 1. The planar notches 4 and V-shaped notches 5 facilitate the removal of cutting material.

[0023] The finishing tool 3 is connected to the base 1 via an adjustment mechanism 6, which allows the radial position of the finishing tool 3 on the base 1 to be adjustable. The adjustment mechanism 6 can have various structures, such as a base plate fixed to the planar notch 4, with the finishing tool 3 slidably connected to the base plate. A set screw is provided on the base plate to connect the finishing tool 3; loosening the set screw allows the position of the finishing tool 3 to be adjusted. Preferably, the finishing tool 3 is a fine-tuning boring head with its own adjustment mechanism 6.

[0024] The axial rear end of the base 1 is provided with an installation structure 7 for connecting the runway processing equipment. The installation structure can be a combination of positioning holes coaxial with the single base 1 and multiple screw holes, with positioning holes for positioning and screw holes for fixing, and connected to the angle head of the equipment.

[0025] Working principle: After the base 1 is installed on the equipment, the equipment drives the base 1 to rotate and the swashplate track 8 to advance axially to the machining position. During the axial feed process, such as Figure 2 As shown, since the tip of the roughing tool 2 is in front of the finishing tool 3, the roughing tool 2 is responsible for removing most of the machining allowance of the housing during roughing. Figure 1As shown, since RJ is greater than RC, after the roughing tool 2 removes most of the machining allowance, the finishing tool 3 follows up to remove the remaining machining allowance. Due to the small cutting amount, the machining accuracy is high. The combined cutting of the roughing tool 2 and the finishing tool 3 is equivalent to a combination of reaming and fine boring.

[0026] Adjusting the finishing tool 3 can compensate for tool wear during machining, resulting in high machining accuracy. Once worn down to the point of being unusable, it can be replaced.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
