Description

Technical Field

[0001] This invention relates to the field of milling machine tool technology, and more specifically to a carbide end milling machine tool with adjustable milling depth. Background Technology

[0002] Milling is a machine tool used to machine workpieces using carbide end mills. During the machining process, a rotating end mill cutter mills the workpiece, generating a large amount of metal chips and dust. Milling machine tools typically collect machining debris through a fixed dust extraction port. However, with the increasing complexity and precision requirements of machined workpieces, existing technologies have many shortcomings.

[0003] Milling machine tools typically use fixed-shaped dust hoods or nozzles for chip removal. The position and shape of the suction port are fixed and cannot be adjusted according to the specific shape and size of the workpiece. The fixed suction port often cannot get close to the periphery of the workpiece, resulting in excessively long chip removal distance. A large amount of chips are scattered on the worktable and fixture, forming dead corners for chip removal. Furthermore, cleaning the machining table and workpiece usually relies on manual operation with a brush, which affects production efficiency and results. It also causes spatial interference with the dust hood or nozzle, making efficient coordination difficult. Summary of the Invention

[0004] This invention provides a milling machine tool for machining carbide end mills that can adapt to the shape of the workpiece, integrate chip suction and cleaning functions, and is easy and efficient to operate, in order to meet the needs of modern precision machining.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0006] In a first aspect, a carbide end milling machine tool with adjustable milling depth includes a base and a Y-axis moving platform fixed on the base.

[0014] Furthermore, the suction component includes:

[0015] The suction pump is fixed on the base and located on one side of the Y-axis moving platform;

[0016] The straw is fixed to the suction end of the air pump;

[0017] The cap is threaded onto one end of the straw.

[0018] The hose has one end connected to the end of the cap and the other end connected to one end of the rubber tube.

[0019] A telescopic tube is installed through the middle of the flexible hose;

[0020] Collect the parts and place them inside the cap and straw.

[0021] Furthermore, the collecting components include:

[0022] A screen is installed inside the lid and the straw, with one end inserted into the inner wall of the lid.

[0023] The net cover is installed at the end of the barrier net closest to the air intake pump;

[0024] The barrier and the cover are connected to each other by a zipper.

[0025] Furthermore, the adjusting positioning component includes:

[0026] The support plate has three parts, which are fixed to the outside of the rubber tube and are located above each row of fixing holes.

[0027] Rubber rings are installed through the support plate;

[0028] A hollow rod is inserted through a rubber ring and is frictionally connected to the rubber ring.

[0029] Furthermore, the screw fastener includes:

[0030] The support ring is fixed to the telescopic end of the electric pole and is coaxially rotatably connected to the rubber tube via a bearing;

[0031] A port is opened at one end of the rubber tube;

[0032] The baffle is fixed to one end of the hose near the rubber tube and is located inside the rubber tube.

[0033] The end of the hose furthest from the suction pump extends into the inlet, and the baffle is connected to one end of the rubber tube via a fixing component.

[0034] Furthermore, the friction element includes:

[0035] A rubber cylinder is installed on the side of the rubber tube away from the support plate and above the conical opening;

[0036] The elastic plate is horizontally positioned inside the rubber cylinder;

[0037] A guide channel is opened above the rubber cylinder;

[0038] A pull rod is positioned above the guide channel and threaded through the guide channel to connect with the elastic plate.

[0039] The cotton brush is fixed to the side of the elastic plate away from the support plate.

[0040] Furthermore, a side plate is fixed to one side of the fixed end of one of the electric poles, and an inclined plate is connected to one end of the side plate. The flexible hose passes through the inclined plate, and a transparent sleeve is connected to the front of the inclined plate. The upper end of the transparent sleeve has an opening.

[0051] The above-described solution of the present invention has at least the following beneficial effects:

[0052] By combining a flexible deformation structure of the rubber tube with a hollow rod positioning mechanism, the chip suction unit can adaptively adjust its shape and position according to the workpiece shape. Under the positioning action of the hollow rod, the rubber tube undergoes controllable bending deformation, allowing multiple conical openings to semi-encircle the workpiece to form close-range chip suction, effectively eliminating dead angles and minimizing the chip suction distance, thus improving the chip suction effect. At the same time, the cleaning and maintenance units are integrated into the chip suction unit structure. The rubber tube can be rotated and its angle adjusted by a screw fastener, allowing the cotton brush to quickly switch from chip suction mode to cleaning mode without occupying additional space or replacing equipment. This achieves space reuse and integrated operation of chip suction, cleaning, and maintenance functions, enabling quick switching between chip suction and cleaning operations, significantly improving work efficiency and cleaning effect.

[0066] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0067] like Figures 1 to 11 As shown, an embodiment of the present invention provides a carbide milling machine tool with adjustable milling depth, including a base 1 and a Y-axis moving platform 2 fixed on the base 1. An X-axis moving platform 3 is provided on the Y-axis moving platform 2, and a body 5 is connected to the base 1. A milling block 8 is raised and lowered on the body 5. A milling cutter 9 is connected to the driving end of the milling block 8, and a motor 10 is connected to the milling block 8 to drive the milling cutter 9 to rotate for milling work. A plurality of fixing holes 4 are evenly opened on the X-axis moving platform 3, and the fixing holes 4 have three rows for mounting fixtures. The machine also includes:

[0068] The dust collection unit is slidably disposed on the outside of the X-axis moving platform 3. It includes a dust collection component that is slidably and vertically connected to the X-axis moving platform 3, and a suction component disposed on the base 1 and detachably connected to the end of the dust collection component to provide suction for the dust collection component. The dust collection component is provided with an adjustment and positioning part to cooperate with the fixed hole 4 to adjust and position the shape of the dust collection component.

[0069] The cleaning section is provided through the dust suction section. It includes a screw fastener connected to the suction component and located inside the suction adjustment component, and a wiping component provided through the suction adjustment component. The angle of the wiping component can be rotated to facilitate cleaning and wiping of the workpiece and the X-axis moving platform 3.

[0070] The maintenance section, connected to the cleaning section and the chip removal section, includes a protective sleeve connected to the wiping component, and a supply component that passes through the adjustment and positioning parts to store and supply lubricating oil. The supply component is connected to the protective sleeve to supply lubricating oil to the protective sleeve, and is protected by the protective sleeve and cooperates with the lubricating oil to maintain the milling cutter 9.

[0071] Specifically, the milling cutter 9 is made of cemented carbide. A lifting rod 6 is fixed on the machine base 1. A support plate 7 is connected to the telescopic end of the lifting rod 6. The end of the support plate 7 is connected to the milling base 8, which is located above the X-axis moving platform 3. A display screen 11 is provided on one side of the machine base 1 to display the operating status of the equipment and facilitate touch operation and control of the milling machine by the operator. The machine base 1 provides stable support for the Y-axis moving platform 2 and the machine body 5. The Y-axis moving platform 2 provides support for the X-axis moving platform 3 and can drive the X-axis moving platform 3 along the X-axis moving platform 3 under the operation of the operator. With the Y-axis translation adjustment position, the X-axis moving platform 3 can provide opening space for the fixed hole 4, the fixed hole 4 can provide the installation and fixing position for the workpiece fixture, and the X-axis moving platform 3 can drive the workpiece fixture to translate and adjust its position along the X-axis under the operation of the operator. The machine body 5 can provide stable support for the lifting rod 6 under the support of the machine base 1. The lifting rod 6 can provide support for the support plate 7. The support plate 7 can stably support the milling base 8. The milling base 8 can provide installation space for the milling cutter 9 and can provide support for the motor 10. After the motor 10 is started, it can drive the milling cutter 9 to rotate through the milling base 8.

[0072] In practical application, the operator can install the workpiece clamping fixture from the fixing hole 4 to a suitable position on the X-axis moving platform 3 using the fixing component. Then, the milling cutter 9 is connected to the lower drive end of the milling base 8. The operator can then control the lifting rod 6 to retract as needed, causing the lifting rod 6 to move the support plate 7 downwards via its telescopic end. The support plate 7 then moves the milling base 8, the milling cutter 9, and the motor 10 downwards together, adjusting the milling depth so that the milling cutter 9 can move to a suitable height for milling the workpiece. The motor 10 is then started, driving the milling cutter 9 to rotate through the milling base 8. The Y-axis moving platform 2 and the X-axis moving platform 3 are then operated as needed to control the clamping fixture and the workpiece it holds to translate and adjust their positions along the X and Y axes, allowing the workpiece to contact the rotating milling cutter 9 during movement, thus enabling the milling cutter 9 to perform milling on the workpiece.

[0073] In a preferred embodiment of the present invention, the suction and adjustment member includes:

[0074] Multiple electric rods 14 are symmetrically arranged on the outside of the X-axis moving platform 3 and are slidably connected to the X-axis moving platform 3.

[0075] The rubber tube 16 is installed at the telescopic end of the electric rod 14 and is located above the X-axis moving platform 3;

[0076] The conical opening 17 has multiple openings that are evenly spaced through the rubber tube 16.

[0077] Specifically, the X-axis moving platform 3 has symmetrically arranged guide grooves 12 on its outer side, and a guide plate 13 is arranged through the inside of the guide grooves 12. The guide plate 13 is frictionally connected to the guide grooves 12 so as to push the guide plate 13 to move by external force and to position it by friction. The guide plate 13 is connected to the electric rod 14 to provide sliding support for the electric rod 14. The electric rod 14 can support the rubber tube 16 through the telescopic end and the support ring 15. The rubber tube 16 can bend and elastically deform under the action of external force. The rubber tube 16 can provide opening space for the conical opening 17. The conical opening 17 can provide a channel for air and milling chips to enter the rubber tube 16.

[0078] The suction components include:

[0079] The suction pump 18 is fixed on the base 1 and located on one side of the Y-axis moving platform 2;

[0080] The straw 19 is fixed to the suction end of the suction pump 18;

[0081] The cap 20 is threaded onto one end of the straw 19;

[0082] One end of the hose 24 is connected to the end of the cap 20, and the other end is connected to one end of the rubber hose 16;

[0083] The telescopic tube 25 is installed through the middle of the flexible tube 24;

[0084] The parts are collected and placed inside the cap 20 and the straw 19.

[0085] Specifically, the base 1 provides a stable support for the suction pump 18, the suction pump 18 provides support for the suction tube 19, the suction tube 19 is threaded and connected to the cap 20, the cap 20 and the suction tube 19 provide a passage for airflow and provide a space for collecting parts, the collecting parts provide a passage for airflow and can intercept and collect milling debris, the hose 24 and the telescopic tube 25 provide a passage for airflow, the telescopic tube 25 is elastic and can extend under the action of external force, and will retract by rebound force when the external force is removed.

[0086] The collected parts include:

[0087] A barrier net 21 is set inside the tube cap 20 and the straw 19, and one end is inserted into the inner wall of one end of the tube cap 20.

[0088] The net cover 23 is installed at the end of the barrier net 21 near the air intake pump 18;

[0089] The barrier net 21 and the net cover 23 are connected to each other by a zipper 22.

[0090] Specifically, the cylinder cover 20 can be inserted into and provide support for the end of the net 21, and the end of the net 21 is connected to the hose 24. The net cover 23 cooperates with the net 21 to intercept debris entering its interior and can provide a passage for air. Workers can remove the net cover 23 by unzipping the zipper 22 to open the opening for dumping the collected debris.

[0091] The adjusting and positioning parts include:

[0092] The support plate 29 has three parts, which are fixed to the outside of the rubber tube 16 and are respectively located above each row of fixing holes 4;

[0093] Glue ring 30, through support plate 29 is set;

[0094] A hollow rod 31 is provided, which passes through the rubber ring 30 and is in frictional connection with the rubber ring 30.

[0095] Specifically, the support plate 29 can provide support for the rubber ring 30 under the support of the rubber tube 16, the rubber ring 30 can provide a through channel for the hollow rod 31, and can use friction to support and position the hollow rod 31. The fixed hole 4 can provide an insertion space for the hollow rod 31, so that the hollow rod 31 can be positioned at the fixed hole 4 in a suitable position.

[0096] In practical application, the operator can push the guide plate 13 with the electric rod 14 as needed, causing the guide plate 13 to slide along the guide groove 12 using external force to overcome friction. This allows the electric rod 14 to move the rubber tube 16 along with the support ring 15 and bearing, moving the rubber tube 16 to the side of the fixture fixed on the X-axis moving platform 3. Simultaneously, the lower end of the hollow rod 31 is aligned with the fixed hole 4 at the current position. The operator also needs to control the extension of the electric rod 14, pushing the support ring 15 upwards with its telescopic end. The support ring 15 then moves the rubber tube 16 upwards to adjust its height, causing the rubber tube 16 to move towards the tapered opening. Adjust position 17 to a suitable height (to facilitate the removal of milling debris from the workpiece held in the fixture). Then, push the hollow rod 31 downwards as needed, allowing it to overcome the friction with the rubber ring 30 and move downwards under external force. This allows the hollow rod 31 to be inserted into the fixed hole 4 at its current position. The three hollow rods 31 can be inserted into fixed holes 4 at different distances from the fixture as needed. The fixed holes 4, with the cooperation of the X-axis moving platform 3, support and position the hollow rods. The hollow rods 31 can be positioned locally on the rubber tube 16 at its current position via the rubber ring 30 and the support plate 29. Then, continue moving towards the fixture along the guide groove 12. Move the electric rod 14, causing it to move both ends of the rubber tube 16 together. This causes the rubber tube 16 to bend and deform under the influence of the external force and the positioning action of the hollow rod 31. Consequently, the rubber tube 16 can bend and move along with the conical opening 17, allowing the rubber tube 16 and the conical opening 17 to encircle the workpiece on the fixture. Then, start the suction pump 18, which draws in air through the suction pipe 19, cylinder cover 20, mesh cover 23, barrier net 21, hose 24, telescopic pipe 25, and rubber tube 16. The air enters the rubber tube 16 through the conical opening 17, while the air inside the rubber tube 16 enters the hose 24 and interacts with the telescopic opening 25. The tube 25, in conjunction with the cylinder cover 20, enters the barrier net 21, passes through the barrier net 21 and the net cover 23, and enters the suction tube 19. Finally, it is sucked in and discharged by the suction pump 18 through the suction tube 19, thereby creating a negative pressure at the conical opening 17. The milling debris is sucked into the conical opening 17 under the action of negative pressure and airflow, passes through the conical opening 17, enters the rubber tube 16, passes through the rubber tube 16, enters the flexible hose 24, and passes through the flexible hose 24 and the telescopic tube 25, passes through the cylinder cover 20, and enters the barrier net 21. The barrier net 21 and the net cover 23 work together to intercept and collect the debris, thereby facilitating the collection of workpiece machining debris, reducing dead zones in debris collection, and improving the debris collection effect.

[0097] As a preferred embodiment of the present invention, the screw fastener includes:

[0098] The support ring 15 is fixed to the telescopic end of the electric rod 14 and is coaxially rotatably connected to the rubber tube 16 through a bearing;

[0099] A port 26 is opened at one end of the rubber tube 16;

[0100] The baffle 27 is fixed to one end of the hose 24 near the rubber tube 16 and is located inside the rubber tube 16;

[0101] The end of the hose 24 away from the suction pump 18 extends into the port 26, and the baffle 27 is connected to one end of the rubber tube 16 by a fixing component.

[0102] Specifically, the electric rod 14 provides support for the support ring 15, the support ring 15 provides rotational support for the rubber tube 16 using the bearing, the rubber tube 16 provides opening space for the port 26, and the hose 24, port 26, support ring 15 and bearing cooperate to allow the rubber tube 16 to rotate after being released from fixation, the hose 24 provides support for the baffle 27, and the end of the rubber tube 16 is connected by a bolt 28, and the bolt 28 is threadedly connected to the baffle 27 to tightly connect the baffle 27 and the rubber tube 16 using the thread action.

[0103] The cleaning components include:

[0104] The rubber cylinder 32 is installed through the rubber tube 16 on the side away from the support plate 29 and is located above the conical opening 17;

[0105] The elastic plate 33 is laterally positioned inside the rubber cylinder 32;

[0106] Guide channel 34 is opened above the rubber cylinder 32;

[0107] Pull rod 36 is positioned above guide channel 34 and is threaded through guide channel 34 to elastic plate 33;

[0108] The cotton brush 38 is fixed to the side of the elastic plate 33 away from the support plate 29.

[0109] Specifically, the rubber tube 16 provides support for the rubber cylinder 32, which can bend and deform along with the rubber tube 16. The elastic plate 33 can deform under the action of external force and rebound when the external force disappears. It can also provide support for the cotton brush 38, which can bend and deform under the action of external force. A screw 37 is connected to the lower part of the pull rod 36, and a threaded ring 35 is connected to the upper part of the elastic plate 33. The threaded ring 35 is threadedly connected to the screw 37. The guide channel 34 provides a through channel and movement space for the screw 37.

[0110] In practical application, after or before workpiece processing, the operator can pull the hollow rod 31 upward to separate it from the fixed hole 4, then rotate and disassemble the bolt 28 to separate it from the retaining plate 27, thereby releasing the rotational fixation of the rubber tube 16. Then, under the support of the support ring 15, the rubber tube 16 is pushed to rotate around the support ring 15, causing the rubber tube 16 to rotate along with the rubber cylinder 32 and the support plate 29. This causes one side opening of the rubber cylinder 32 to face vertically downwards. Simultaneously, the rubber cylinder 32 will rotate and adjust the position of the elastic plate 33 and the cotton brush 38. The conical opening 17 will also face downwards under the influence of the rubber tube 16. Then, the pull rod 36 is rotated, causing the pull rod 36 to rotate along with the screw 37, loosening the screw 37 from the threaded ring 35 using rotational power (note: the screw 37 should not be completely separated from the threaded ring 35). This releases the positioning of the elastic plate 33, and the position is then released via the pull rod 36. 6. The screw 37 and threaded ring 35 pull the elastic plate 33 along the guide 34, causing the elastic plate 33 to use external force to drive the cotton brush 38 to extend from the rubber cylinder 32 to a suitable position. Then, the pull rod 36 is rotated, causing the screw 37 to tighten with the threaded ring 35 through the thread action. This causes the pull rod 36 and the elastic plate 33 to come closer together and squeeze the rubber cylinder 32 to achieve a fixed positioning effect. Afterwards, the operator can control the extension and retraction of the electric rod 14 to adjust the height of the cotton brush 38 according to the actual needs. Then, the electric rod 14 is pushed to move horizontally along the guide groove 12, thereby moving the cotton brush 38 horizontally as well. During the horizontal movement, the cotton brush 38 can brush off the dust and impurities adhering to the X-axis moving platform 3, the fixture, or the workpiece. At the same time, the suction pump 18 can be started to suck up the dust and impurities brushed off through the conical mouth 17, improving the cleanliness of the milling working environment and preventing the adhering dust and impurities from affecting the milling effect or the observation of the operating equipment and workpiece.

[0111] In a preferred embodiment of the present invention, a side plate 39 is fixed to one side of the fixed end of one of the electric poles 14, and a sloping plate 40 is connected to one end of the side plate 39. A flexible hose 24 passes through the sloping plate 40, and a transparent sleeve 41 is connected to the front of the sloping plate 40. The upper end of the transparent sleeve 41 has an opening.

[0112] Specifically, the side plate 39 can provide support for the inclined plate 40 under the support of the electric rod 14, the inclined plate 40 can provide support for the transparent sleeve 41, and the upper opening of the transparent sleeve 41 can provide space for inserting drawings.

[0113] In practical application, workers can insert the workpiece machining drawings into the inside of the transparent sleeve 41 before milling. Under the protection of the transparent sleeve 41 and the support of the inclined plate 40, the drawings are provided with a place and protection. Workers can view the placed machining drawings through the transparent sleeve 41 during the milling process, which provides protection for the machining drawings and facilitates observation.

[0114] In a preferred embodiment of the present invention, the supply component includes:

[0115] Threaded cap 42, with threads passing through the upper end of hollow rod 31;

[0116] T-bar 44, movable through threaded cap 42 is provided;

[0117] The triangular sealing ring 43 is located on the outside of the T-rod 44 and between the T-rod 44 and the threaded cap 42, and is connected to the threaded cap 42.

[0118] Piston 45 is fixed to the lower end of T rod 44 and fits against the inner wall of hollow rod 31.

[0119] Specifically, the hollow rod 31 is made of transparent material, which allows staff to easily observe the internal liquid level. It can also connect to the threaded cover 42 using the threaded action and provide support for the threaded cover 42. The threaded cover 42 can stably support the triangular sealing ring 43. The triangular sealing ring 43 can fit against the T rod 44 using its elasticity to play a sealing role, preventing the liquid inside the hollow rod 31 from flowing out to the outside through the gap between the threaded cover 42 and the T rod 44. The piston 45 can move up and down against the inner wall of the hollow rod 31 under the action of external force to promote the flow of liquid.

[0120] The protective kit includes:

[0121] A semi-circular plate 46 is fixedly installed above the rubber cylinder 32;

[0122] Sponge 47 is disposed on the inner side of semi-circular plate 46 and rubber cylinder 32 and is connected to cotton brush 38;

[0123] The cotton brush 38 extends to the inside of the semi-circular plate 46 and wraps around the sponge 47 in a ring.

[0124] Pipe 48 is installed with one end passing through hollow rod 31 and the other end passing through semi-circular plate 46 and contacting sponge 47.

[0125] Specifically, the rubber cylinder 32 provides support for the semi-circular plate 46, the semi-circular plate 46 provides protection for the cotton brush 38, the cotton brush 38 provides stable support for the sponge 47, the sponge 47 provides an insertion space for the milling cutter 9, and has elasticity and absorbency to fit against the outer surface of the milling cutter 9, and can absorb liquid and apply it to the surface of the milling cutter 9. The pipe 48 provides a channel for the liquid in the hollow rod 31 to enter the sponge 47, and the pipe 48 has redundant length to avoid affecting the lifting and lowering movement of the hollow rod 31.

[0126] In practical application, the operator can rotate the threaded cap 42 in the initial stage to separate the threaded cap 42 from the hollow rod 31, thereby opening the opening at the upper end of the hollow rod 31. Then, lubricating oil (maintenance liquid) is injected into the inner side of the hollow rod 31. The threaded cap 42 is then threadedly connected to the hollow rod 31 using the thread action, so that the hollow rod 31 and the threaded cap 42 cooperate to store the maintenance liquid between the piston 45 and the threaded cap 42.

[0127] After the milling operation is completed, the operator can unscrew bolt 28 and rotate rubber tube 16, causing rubber tube 16 to rotate together with rubber cylinder 32 and support plate 29. Rubber cylinder 32 then rotates cotton brush 38 and sponge 47 together until one end face of sponge 47 and cotton brush 38 is rotated to a vertically upward position. Bolt 28 is then tightened to fix the position of rubber tube 16. Subsequently, the operator can control the X-axis moving platform 3 to move along the X-axis to adjust its position, or move rubber tube 16 along guide groove 12, aligning the center of sponge 47 with the center of milling cutter 9. Then, the lifting rod 6 is retracted, causing milling cutter 9 to move downwards and insert into the inside of sponge 47, thus enveloping the sponge 47. The machine tool wraps around the milling surface and outer surface of the milling cutter 9. At the same time, the operator can pull the T-bar 44, which will cause the T-bar 44 to deform the triangular sealing ring 43 under the action of external force. The T-bar 44 can then use external force to drive the piston 45 to move along the hollow rod 31 towards the triangular sealing ring 43. During the movement, the piston 45 can push the maintenance liquid in the hollow rod 31 to flow into the drain pipe 48, and then flow through the semi-circular plate 46 into the sponge 47 for absorption. The sponge 47 can then seep and apply the absorbed maintenance liquid to the surface of the wrapped milling cutter 9, thus providing convenient protection and maintenance for the milling cutter 9 when the milling machine is not in use.

[0128] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
