Description

Technical Field

[0001] This utility model relates to the field of machining technology, and more specifically, to a reusable turbine housing machining tool. Background Technology

[0002] Turbocharger housings are typically cast from high-temperature alloy materials, which are characterized by being difficult to machine, having strong metal adhesion, being difficult to break chips, and causing rapid tool wear. When machining the turbine housing using methods such as turning and milling, there is a large allowance between the dimensions of the cast turbine housing blank and the dimensions after finishing. During cutting, the tool will generate huge friction and extrusion forces with the part, creating a high-temperature and high-pressure state. This affects the machining performance of the degraded tool. Due to the high hardness of the hard layer on the blank surface, the cutting edge of the tool will gradually develop notches, micro-chipping, and other phenomena, leading to tool failure and wear.

[0003] In existing production, mechanically clamped quick-change inserts are commonly used for turning or milling. These inserts offer advantages such as quick replacement, a protective coating that makes the tool more durable, and standardized insert models that facilitate replacement. However, they also have drawbacks such as higher prices, higher parts production costs, and the need for single-use inserts that do not require re-sharpening. When machining heat-resistant stainless steel alloy volutes that are difficult to cut, the cutting edge of the insert wears out quickly, resulting in short tool life, high wear and tear, and high parts production costs. Summary of the Invention

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a reusable turbine housing machining tool. By performing certain re-grinding treatment on the cutting edge of the quick-change insert's rake face, new chip removal grooves and tool cutting edges are formed, improving the insert's reusability rate, solving the problem of disposable inserts, increasing the reusability rate of indexable inserts, reducing parts production costs and tool wear, reducing the number of tools purchased, and providing valuable experience for the reuse and re-grinding of other types of inserts in the future, thereby improving enterprise competitiveness and enhancing technological application capabilities.

[0005] According to the technical solution provided by this utility model, a reusable turbine housing machining tool includes: a double-edged boring tool holder, the bottom surface of which is detachably connected to a boring tool holder, and quick-change inserts are installed on both outer walls of the boring tool holder, with cutting edges provided on both outer walls of the two quick-change inserts.

[0006] As a further improvement of this utility model, the bottom surface of the boring tool holder is provided with a turbine housing to be machined.

[0007] As a further improvement of this utility model, mounting holes are provided on one side of the outer wall of both quick-change blades.

[0008] As a further improvement of this utility model, chip removal grooves are provided on one side of the outer wall of both quick-change blades.

[0009] As a further improvement of this utility model, fixing holes are provided on both outer walls of the boring tool holder.

[0010] As a further improvement of this utility model, the two fixing holes are respectively engaged with the corresponding quick-change blades.

[0011] Compared with existing technologies, this utility model has the following advantages:

[0012] This reusable turbine housing machining tool, by performing a certain re-grinding process on the cutting edge of the quick-change insert's rake face, forms new chip removal grooves and tool cutting edges, improving the insert's reusability and solving the problem of single-use inserts. It increases the reusability of indexable inserts, reduces parts production costs and tool wear, and reduces the number of tools purchased. It provides valuable experience for the subsequent reuse and re-grinding of other types of inserts, enhancing the company's competitiveness and strengthening its technological application capabilities.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] like Figures 1-7 As shown, it includes a double-edged boring bar holder 1, a boring bar holder 2, a turbine housing to be machined 3, a quick-change insert 4, a chip removal groove 5, and a mounting hole 6, etc.

[0022] like Figures 1-7 As shown, this utility model discloses a reusable turbine housing machining tool, comprising: a double-edged boring tool holder 1, wherein a boring tool holder 2 is detachably connected to the bottom surface of the double-edged boring tool holder 1, and quick-change inserts 4 are installed on both outer walls of the boring tool holder 2, and cutting edges are provided on both outer walls of the two quick-change inserts 4.

[0023] In a specific embodiment of this utility model, a boring bar holder 2 is mounted on a double-edged boring bar shank 1, and then the turbine housing 3 to be machined is machined using a quick-change insert 4 on the boring bar holder 2. After the quick-change insert 4 wears, the cutting edge on the rake face of the quick-change insert 4 is re-grinded to a certain width and height, wherein the height is re-grinded by 0.2-0.5mm and the width is re-grinded by 1.0-1.5mm, forming a new chip removal groove and cutting edge. After the surface of the quick-change insert 4 is recoated, the insert becomes more durable and resistant to wear. Wear reduction improves the reusability of cutting tools and solves the problem of single-use cutting tools. After actual machining on a machine tool, the cutting tools that have been refurbished in this way have been verified to maintain the cutting edge strength of the tool by grinding flat and wide chip grooves. At the same time, it is conducive to the smooth discharge of iron chips during tool machining and removes a large amount of heat generated by the tool during cutting, thereby reducing the wear between iron chips and the cutting edge, keeping the tool in a good cutting condition, maintaining the tool life of the original new cutting tool, effectively improving the reusability of cutting tools, and reducing the part machining cost.

[0024] Specifically, the bottom surface of the boring tool holder 2 is provided with the turbine housing 3 to be machined.

[0025] In this embodiment, the turbine housing 3 to be machined is machined by the quick-change insert 4 installed on the boring tool holder 2.

[0028] Specifically, chip removal grooves 5 are provided on one side of the outer wall of both quick-change blades 4.

[0029] In this embodiment, the chips generated during cutting are discharged through the chip removal groove 5, and heat is also carried away.

[0030] Specifically, fixing holes are provided on both outer walls of the boring tool holder 2.

[0031] In this embodiment, the quick-change blade 4 is installed by the cooperation of the fixing hole and the mounting hole 6.

[0032] Specifically, the two fixing holes are respectively matched with the corresponding quick-change blades 4.

[0033] In this embodiment, the quick-change blade 4 is installed by the cooperation of the fixing hole and the mounting hole 6.

[0034] Working principle: The boring tool holder 2 is installed through the double-edged boring tool holder 1, and the turbine housing 3 to be machined is then machined through the quick-change insert 4 on the boring tool holder 2. After the quick-change insert 4 wears, the cutting edge on the rake face of the quick-change insert 4 is re-grinded to a certain width and height, with the height re-grinding being 0.2-0.5mm and the width re-grinding being 1.0-1.5mm, forming a new chip removal groove and tool cutting edge. After the surface of the quick-change insert 4 is recoated, the insert becomes more durable and wear-resistant, improving the reusability of the insert and solving the problem of disposable inserts.

[0035] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.
