Description

Technical Field

[0001] This utility model relates to the technical field of milling cutter fixture bases, specifically a milling cutter fixture base with coolant flow guidance. Background Technology

[0002] In the field of machining, the milling cutter fixture base is a core component connecting the machine tool spindle and the milling cutter. Its main functions are to achieve stable clamping of the milling cutter, power transmission, and ensure machining accuracy. With the increasing demand from industries such as aerospace and automotive molds for machining difficult-to-machine materials (such as titanium alloys and high-temperature alloys) and complex structural parts, the large amount of heat generated during milling and the accumulation of chips have become key issues affecting machining quality and efficiency.

[0003] The existing publicly available technical solution CN218253230U discloses a water-cooled power tool holder. The cooling pipe of this tool holder is arranged in a transverse insertion method into the fixed seat. This transverse arrangement occupies a lot of extra transverse space. When the fixed seat needs to enter the narrow working area such as the deep cavity of the workpiece, narrow gap, or the inner side of the complex curved surface, the transversely extended cooling pipe is very likely to interfere with the contour of the workpiece or the surrounding parts of the machine tool, causing the fixed seat to be unable to move smoothly into place. As a result, it is difficult to effectively process the corner areas of the workpiece, the bottom of the deep cavity, and other critical parts, thus limiting the adaptability of the tooling base to complex structural parts. Utility Model Content

[0004] Given that the existing devices use a lateral insertion method for the cooling pipes, this lateral arrangement occupies a lot of lateral space. When the fixture needs to enter a narrow working area such as a deep cavity, narrow gap, or the inside of a complex curved surface of the workpiece, the laterally protruding cooling pipe is very likely to interfere with the contour of the workpiece or the surrounding parts of the machine tool, causing the fixture to be unable to move smoothly into place. This makes it difficult to effectively process key parts such as the corner areas of the workpiece and the bottom of the deep cavity, thus limiting the adaptability of the tooling base to complex structural parts.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A milling cutter fixture base with coolant flow includes a cooling component; a fixing component for modularly fixing parts; and an adjustment component for adjusting the cutting depth. The cooling assembly includes: a mounting base; a coolant injection chamber located in the middle of the mounting base; and a mounting head located below the mounting base.

[0006] As a further improvement of this utility model, the cooling component further includes: a first sealing ring and a second sealing ring; the first sealing ring is installed at the lower middle part of the fixed base; the second sealing ring is installed at the lower middle part of the mounting head.

[0007] As a further improvement of this utility model, the cooling component further includes a flow guide tube; the flow guide tube is fixed inside the upper part of the mounting head, and the upper end of the flow guide tube is flush with the upper end of the mounting head.

[0008] As a further embodiment of this utility model, the fixing component further includes: a limiting groove and a fixing bolt hole; the limiting groove is located on the upper front side of the tool; the fixing bolt hole is located on the upper right side of the tool.

[0009] As a further embodiment of this utility model: the fixing component further includes: a fixing bolt and a second liquid outlet; the fixing bolt is threaded into the inside of the fixing bolt hole; the second liquid outlet is located on the lower right side of the cutter.

[0010] As a further embodiment of this utility model, the fixing component further includes: a first liquid outlet; the first liquid outlet is opened inside the cutter and extends through the upper and lower end faces of the cutter.

[0011] As a further embodiment of this utility model: the adjustment assembly further includes: a fixed cylinder; the fixed cylinder is fixed to the outer surface of the sealed bearing, the cutting adjustment cylinder is rotatably connected to the fixed cylinder through the sealed bearing, and the inner wall of the cutting adjustment cylinder is provided with a threaded groove.

[0012] As a further embodiment of this utility model: the adjustment component further includes: a protective plate; the protective plate is threadedly connected to the center of the surface of the fixing bolt, and the protective plate is slidably connected to a groove opened inside the mounting head.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model forms a double sealing structure by setting a first sealing ring and a second sealing ring.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Example 1: Please refer to Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a milling cutter tooling base with coolant flow, including a cooling component 1; a fixing component 2 for modularly fixing parts; and an adjusting component 3 for adjusting the cutting depth. The cooling assembly 1 includes: a mounting base 101; a coolant injection chamber 102 opened in the middle of the mounting base 101; and a mounting head 106 disposed below the mounting base 101; The fixing component 2 includes: a fixing member 201 welded to the upper part of the surface of the mounting head 106; and a cutting tool 202 installed inside the lower part of the mounting head 106; The adjustment assembly 3 includes: a cutting adjustment cylinder 301 threadedly connected to the surface of the mounting head 106; and a sealed bearing 302 disposed on the lower part of the surface of the cutting adjustment cylinder 301.

[0020] Specifically, the cooling component 1 also includes: a first sealing ring 104 and a second sealing ring 105; the first sealing ring 104 is installed at the lower middle part of the fixed base 101; the second sealing ring 105 is installed at the lower middle part of the mounting head 106.

[0021] Furthermore, the first sealing ring 104 at the lower center of the fixed seat 101 is in close contact with the upper end face of the mounting head 106, and the second sealing ring 105 at the lower center of the mounting head 106 surrounds the mating gap between the cutter 202 and the mounting head 106, and the two together block the leakage path of the coolant.

[0022] Specifically, the cooling component 1 also includes: a guide tube 103; the guide tube 103 is fixed inside the upper part of the mounting head 106, and the upper end of the guide tube 103 is flush with the upper end of the mounting head 106.

[0023] Furthermore, the lower end face of the guide tube 103 is flush with the lower end face of the mounting head 106.

[0024] Specifically, the fixing component 2 also includes: a limiting groove 203 and a fixing bolt hole 204; the limiting groove 203 is located on the upper front side of the tool 202; the fixing bolt hole 204 is located on the upper right side of the tool 202.

[0025] Furthermore, the cutting tool 202 is inserted into the mounting head 106 through the protrusion structure corresponding to the inner wall of the mounting head 106 via the limiting groove 203, and then the fixing bolt 205 is screwed into the fixing bolt hole 204 of the cutting tool 202.

[0026] In use, the first step is to align and fix the mounting base 101 with the machine tool spindle. Then, the fixing member 201 is fastened to the lower end of the mounting base 101 using external bolts. Since the fixing member 201 is pre-welded to the upper end of the mounting head 106, after the bolts are locked, the mounting head 106 forms a rigid connection with the mounting base 101 along with the fixing member 201, completing the fixation of the entire base's core support structure. Next, the cutting tool 202 is inserted into the mounting head 106 through the corresponding protrusion on the inner wall of the mounting head 106 via the limiting groove 203. Finally, the fixing bolt 205 is screwed into the fixing mechanism of the cutting tool 202. Inside the bolt hole 204, until the end of the fixing bolt 205 presses against the inner wall of the mounting head 106, completely locking the tool 202. Then, the cooling system is activated, and coolant is injected from the coolant injection chamber 102 in the middle of the fixing seat 101, flowing downward along the pre-set guide tube 103 inside the mounting head 106. During this process, the first sealing ring 104 in the middle of the lower end of the fixing seat 101 is in close contact with the upper end face of the mounting head 106, and the second sealing ring 105 in the middle of the lower end of the mounting head 106 surrounds the fit gap between the tool 202 and the mounting head 106. Together, they block the leakage path of the coolant.

[0027] In summary, this utility model forms a double sealing structure by setting a first sealing ring 104 and a second sealing ring 105. The first sealing ring 104 is in close contact with the mating surface of the fixing seat 101 and the mounting head 106, and the second sealing ring 105 surrounds the gap between the mounting head 106 and the tool 202, effectively blocking the coolant leakage path and improving the sealing performance and reliability of the cooling system.

[0028] Example 2: Please refer to Figures 1-5 This is the second embodiment of the present utility model.

[0029] Specifically, the fixing component 2 also includes: a fixing bolt 205 and a second liquid outlet 207; the fixing bolt 205 is threaded into the inside of the fixing bolt hole 204; the second liquid outlet 207 is located on the lower right side of the cutter 202.

[0030] Furthermore, the coolant flows out from the second outlet 207, flushing away the chips generated in the cutting area, and assisting in chip removal while cooling down the area.

[0031] Specifically, the fixing component 2 also includes: a first liquid outlet 206; the first liquid outlet 206 is opened inside the cutter 202 and extends through the upper and lower end faces of the cutter 202.

[0032] Furthermore, the coolant flows directly to the cutting edge area of ​​the tool 202 through the first outlet 206, precisely cooling the high-speed friction of the cutting edge.

[0033] Specifically, the adjustment assembly 3 also includes: a fixed cylinder 303; the fixed cylinder 303 is fixed to the outer surface of the sealed bearing 302, the cutting adjustment cylinder 301 is rotatably connected to the fixed cylinder 303 through the sealed bearing 302, and the inner wall of the cutting adjustment cylinder 301 is provided with a threaded groove.

[0034] Furthermore, the cutting adjustment cylinder 301 drives the fixed cylinder 303 to move downward synchronously through the sealed bearing 302.

[0035] Specifically, the adjustment component 3 also includes: a protective plate 304; the protective plate 304 is threaded to the center of the surface of the fixing bolt 205, and the protective plate 304 is slidably connected to a groove opened inside the mounting head 106.

[0036] Furthermore, the protective plate 304 will slide in the groove inside the mounting head 106 as the fixing bolt 205 moves, preventing the cutting chips generated from entering the interior.

[0037] In use, the coolant entering the tool 202 flows directly to the cutting edge area of ​​the tool 202 through the first outlet 206, precisely cooling the high-speed friction of the cutting edge. The other coolant flows out from the second outlet 207 on the side of the tool 202, flushing away the chips generated in the cutting area. This cooling process assists in chip removal, preventing chip accumulation from affecting machining accuracy. When adjusting the cutting depth, the cutting adjustment cylinder 301 in the adjustment assembly 3 is rotated. Because the threads on the inner wall of the cutting adjustment cylinder 301 engage with the threads on the surface of the mounting head 106, the cutting adjustment cylinder 301 moves downwards along the axis of the mounting head 106 during rotation. At this time, the fixing bolt 205 passes through the fixing cylinder 303, the mounting head 106, and the protective plate 304 in sequence, finally connecting to the tool through a thread. Inside the fixing bolt hole 204 of the fixture 202, the fixing bolt 205 forms an axial constraint on the fixing cylinder 303, keeping the fixing cylinder 303 stationary. The cutting adjustment cylinder 301 is rotatably connected to the fixing cylinder 303 through the sealing bearing 302. The downward movement of the cutting adjustment cylinder 301 drives the fixing cylinder 303 to move downward synchronously through the sealing bearing 302. The fixing cylinder 303 then pulls the tool 202 downward through the fixing bolt 205, thereby changing the length of the tool 202 extending out of the mounting head 106 and adjusting the effective cutting depth. During the adjustment process, the protective plate 304 slides in the groove inside the mounting head 106 as the fixing bolt 205 moves, preventing the waste chips generated during cutting from entering the interior and avoiding the waste chips from getting stuck and affecting the adjustment accuracy or blocking the guide pipe 103.

[0038] In summary, this invention achieves dual-path cooling through a first liquid outlet 206 inside the tool 202 and a second liquid outlet 207 on the side. The first liquid outlet 206 precisely guides the cooling to the cutting edge area, while the second liquid outlet 207 flushes the chip accumulation area. Cooling and chip removal work together to avoid the impact of secondary cutting on machining accuracy. This invention also achieves precise adjustment of the cutting depth through the threaded engagement between the cutting adjustment cylinder 301 and the mounting head 106, combined with the rotatable connection between the sealed bearing 302 and the fixed cylinder 303. Simultaneously, the protective plate 304 slides synchronously with the fixing bolt 205, preventing waste chips from entering the internal gaps of the mounting head 106 and ensuring the long-term stable operation of the adjustment mechanism.

Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.
