Description

Technical Field

[0001] This invention relates to the field of horizontal milling equipment technology, and more particularly to a horizontal milling machine tool. Background Technology

[0002] Horizontal milling machine tools are commonly used metal cutting equipment in the field of machining, and are widely used for milling various boxes, shells, molds and complex structural parts. Traditional horizontal milling machine tools usually include a bed, a workpiece moving module and a tool moving module fixed to the bed. The workpiece moving module is used to clamp and move the workpiece in the horizontal plane, while the tool moving module drives the milling spindle to move up and down vertically to realize the milling of the upper surface and side walls of the workpiece.

[0003] As the manufacturing industry continues to demand higher processing efficiency and precision, many complex parts need to undergo both rough machining with large allowance and high-precision finishing processes simultaneously in a single setup.

[0004] Currently, existing horizontal milling machines are typically equipped with only a single milling spindle and a single cutting tool. For roughing, large-diameter, heavy-duty milling cutters are used for high-cutting-rate machining, while for finishing, finish cutters or ball end mills are required for low-cutting-rate machining. While this machining method is usable, the cumbersome tool changing process, coupled with the need for tool resetting afterward, consumes significant auxiliary time and reduces workpiece machining efficiency. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide a horizontal milling machine tool to solve the problem that existing horizontal milling machine tools are usually equipped with only a single milling spindle and a single tool. When performing roughing and finishing, the tool changing process is cumbersome, and the tool needs to be re-set after the change, which consumes a lot of time and reduces the machining efficiency of the workpiece.

[0006] To achieve the above objectives, the present invention provides a horizontal milling machine tool, comprising a bed and a workpiece moving module and a tool moving module fixed to the bed. The workpiece moving module has a workpiece moving stage capable of multiple degrees of freedom, and the tool moving module has a vertical moving stage capable of reciprocating vertically.

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0037] It should be noted that, unless otherwise defined, the technical or scientific terms used in this invention should have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains.

[0038] In one embodiment, please refer to Figures 1 to 5 As shown, the present invention provides a horizontal milling machine tool, including a bed and a workpiece moving module 1 and a tool moving module 2 fixed to the bed. The workpiece moving module 1 has a multi-degree-of-freedom workpiece moving stage 101, and the tool moving module 2 has a vertical moving stage 201 capable of reciprocating vertically. A rotary table 3 is fixed on the vertical moving stage 201, and a milling module is fixed on the rotary table 3. The bed is horizontally placed, the workpiece moving module 1 is fixed to one side of the bed, the multi-degree-of-freedom workpiece moving stage 101 can move in opposite directions along the length and width of the bed, and is used to clamp the workpiece to be processed and drive the workpiece to move horizontally. The tool moving module 2 is fixed to the other side of the bed, the vertical moving stage 201 is used to drive the milling module to move vertically, the rotary table 3 can rotate 360 ​​degrees, and the milling module is fixed to the table surface of the rotary table 3. An external power motor is fixed on the rotary table 3 to provide power to the milling module.

[0039] The milling module includes a rotating base 4, a first cutting tool 5, a rotating arm 6, a power spindle 7, and a driven assembly.

[0040] The rotating base 4 is fixedly connected to the rotating table 3 by bolts and has a mounting cavity 401.

[0041] The first cutting tool 5 has a cutting tool spindle 51, which is rotatably mounted on the rotary table 3. The axis of rotation of the cutting tool spindle 51 is set along the length of the rotary base 4. Multiple first cutting blades 52 are provided on the outer wall of the first cutting tool 5. The end of the cutting tool spindle 51 extends into the mounting cavity 401 and is fixed to the first driven end 8 by bolt connection. The power of the power motor is transmitted to the first driven end 8 through the power spindle 7, thereby driving the first cutting tool 5 to rotate at high speed for machining the upper surface or side wall of the workpiece, and is capable of large-mass cutting.

[0042] The rotating arm 6 is rotatably connected to the rotary table 3 and can rotate within a certain range around the length of the rotating base 4. A second cutting tool 9 is rotatably mounted on it, and the rotation axis of the second cutting tool 9 is perpendicular to the rotation axis of the rotating arm 6. A second blade 91 is provided on the outer wall of the second cutting tool 9. The end of the second cutting tool 9 facing closer to the rotating arm 6 is fixed to the second driven end 10 by bolts. The power of the power motor is transmitted to the second driven end 10 through the power spindle 7 and the second output end 12, thereby driving the second cutting tool 9 to rotate at high speed. It can perform chamfering, inclined hole drilling and milling, inclined surface milling and T-slot machining on the workpiece at multiple angles to achieve high-precision cutting. Both the first driven end 8 and the second driven end 10 adopt a wedge block structure.

[0043] The power spindle 7 is rotatably connected to the rotating base 4 and is arranged along the axial direction of the rotary table 3. One end of the spindle 7 extends out of the rotating base 4, and the other end extends into the mounting cavity 401. The upper end of the power spindle 7 is connected to the output shaft of an external power motor via a coupling.

[0044] The driven component is disposed in the mounting cavity 401 and drivenly connected to the power spindle 7. It has a first output end 11 and a second output end 12. The first output end 11 can engage with the first driven end 8 and drive the first driven end 8 to rotate. The second output end 12 can engage with the second driven end 10 and drive the second driven end 10 to rotate.

[0045] Working principle:

[0046] When a large amount of machining is required, the drive motor starts and the output shaft of the drive motor rotates. At this time, the rotating arm 6 is retracted to a non-interference angle (such as being placed horizontally). The first output end 11 engages with the first driven end 8, driving the first tool 5 to rotate. Combined with the feed of the workpiece moving table 101, the workpiece is milled with a large amount of machining allowance.

[0047] When high-precision machining is required, the vertical moving table 201 is raised, the rotating arm 6 rotates, causing the second tool 9 to rotate to a set angle, the drive motor is started, the output shaft of the drive motor rotates, the second output end 12 engages with the second driven end 10, driving the second tool 9 to rotate, and combined with the feed of the workpiece moving table 101, the workpiece is milled with high precision.

[0048] Specifically, in this example, the first tool 5 is used to cut the workpiece. The first tool 5 has a strong structural rigidity and excellent anti-torsion performance, and can withstand heavy milling under large cutting volume, ensuring the roughness and flatness of the machined surface and improving the processing efficiency of the horizontal milling machine. At the same time, by using the combination of the rotating arm 6, the driven component and the second tool 9, chamfering, inclined hole drilling and milling, inclined surface milling and T-slot machining of the workpiece can be performed at multiple angles, realizing high-precision cutting of the workpiece, avoiding the disassembly and positioning of the workpiece and improving processing efficiency.

[0049] In an optional example, please refer to Figures 1 to 7 As shown, the driven assembly includes a driven spindle 13 rotatably mounted in the mounting cavity 401. The driven spindle 13 can slide back and forth along the length of the rotating base 4. The first output end 11 is fixed to one end of the driven spindle 13 near the first tool 5 by bolt connection. The second output end 12 is fixed to the other end of the driven spindle 13 near the second tool 9 by bolt connection. A switching ring 14 that can move back and forth along the length of the rotating base 4 is installed in the mounting cavity 401. The switching ring 14 is connected to the driven spindle 13 by rotation and can drive the driven spindle 13 to slide back and forth. The switching ring 14 has a first state and a second state.

[0050] When the switching ring 14 is in the first state, large margin machining is performed, the first output end 11 engages with the first driven end 8 for transmission, and the second output end 12 disengages from the second driven end 10.

[0051] When the switching ring 14 is in the second state, high-precision machining is performed, the second output end 12 engages with the second driven end 10 for transmission, and the first output end 11 disengages from the first driven end 8.

[0052] Specifically, this example uses the sliding of the driven spindle 13 to switch the power between the first tool 5 and the second tool 9, avoiding the power loss caused by simultaneously driving the rotation of the first tool 5 and the second tool 9, ensuring the rotation speed of the first tool 5 and the second tool 9, suppressing the cutting vibration caused by the synchronous rotation of the first tool 5 and the second tool 9, and improving the flatness and roughness of the machined surface.

[0053] In an optional example, please refer to Figures 1 to 7As shown, the power spindle 7 extends into the mounting cavity 401. A drive bevel gear 15 is fixedly mounted on its outer wall via a key connection. A first driven shaft 16 and a second driven shaft 17, arranged along the length of the rotating base 4, are mounted in the mounting cavity 401 via a bearing connection. A driven bevel gear 18 and a first spur gear 19 are mounted on the outer wall of the first driven shaft 16 via a key connection. The drive bevel gear 15 and the driven bevel gear 18 mesh. A second spur gear 20 is fixedly mounted on the outer wall of the second driven shaft 17 via a key connection. An internal bearing seat 21 is fixed in the mounting cavity 401 via a bolt connection. A third spur gear 22 is mounted on the internal bearing seat 21 via a bearing connection. A sliding through groove 221 is provided at the end of the third spur gear 22. The driven spindle 13 is slidably inserted into the sliding through groove 221 via a spline connection.

[0054] Specifically, this example uses the orthogonal shaft transmission of the driving bevel gear 15 and the driven bevel gear 18, the meshing of the first spur gear 19 and the second spur gear 20, and the meshing of the second spur gear 20 and the third spur gear 22 to form a two-stage gear transmission chain. The tooth ratio of each gear pair can be flexibly adjusted according to actual machining requirements to ensure the stability of tool rotation. Furthermore, the driven spindle 13 is slidably connected to the third spur gear 22 through a spline pair. The spline pair has a large bearing area and high contact stiffness, which can reliably transmit the large torque generated during heavy-duty rough machining, avoiding the stress concentration problem when using a flat key or a single pin to transmit torque. At the same time, the spline pair has good guiding properties, ensuring the smoothness and positional accuracy of the driven spindle 13 when it reciprocates under the drive of the switching ring 14, and providing rapid response.

[0055] In an optional example, please refer to Figures 1 to 7As shown, the driven spindle 13 has an outwardly extending driven extension flange 131 on its outer wall. A limiting ring groove 132 is formed on the outer wall of the driven extension flange 131. A limiting ring portion 141 matching the limiting ring groove 132 is formed on the inner wall of the switching ring 14. A guide rod 23 is fixed in the mounting cavity 401 by bolts. A switching lug 142 is formed on the outer wall of the switching ring 14. A guide groove matching the guide rod 23 is formed on the switching lug 142. The guide rod 23 is slidably inserted into the guide groove. A drive telescopic cylinder 24 is fixed to the outer wall of the rotating base 4 by bolts. A guide bracket 25 is fixed to the telescopic end of the drive telescopic cylinder 24 by bolts. A guide sliding hole is formed on the guide bracket 25. The sliding mechanism is fitted onto the outer wall of the guide rod 23. An elastic block 26 is fixed to the guide bracket 25 by bolts. The elastic block 26 is fixedly connected to the switching lug 142 by bolts. A power channel 71 is opened at the end of the power spindle 7 along the axial direction, which is used for wiring. The external power cable passes through the power channel 71 and is electrically connected to the rotating end of the conductive slip ring 28. A slip ring bracket 27 is fixed in the mounting cavity 401 by bolts. A conductive slip ring 28 is fixed on the slip ring bracket 27 by bolts. The rotating end of the conductive slip ring 28 is fixedly connected to the end of the power spindle 7 by bolts. The conductive slip ring 28 is electrically connected to the drive telescopic cylinder 24. Among them, the elastic block 26 can be made of rubber, plastic or other materials; a conductive slip ring 2 is externally connected to the rotary table 3, and the rotating end of the conductive slip ring 2 is fixedly connected to the power spindle 7 by a key connection and electrically connected to the power cable; the drive telescopic cylinder 24 is electrically driven and controls the telescopic movement by the power provided by the conductive slip ring 28.

[0056] Specifically, in this example, the guide groove on the switching lug 142 slides in conjunction with the guide rod 23 in the mounting cavity 401, providing precise linear guidance for the reciprocating movement of the switching ring 14. This prevents the switching ring 14 from deflecting or jamming during movement, ensuring that the first output end 11 and the first driven end 8, and the second output end 12 and the second driven end 10 can be accurately aligned and meshed, improving the repeatability of gear shifting. Furthermore, by opening an axial power channel 71 inside the power spindle 7 and cooperating with the conductive slip ring 28 set in the mounting cavity 401, an electrical transmission path is constructed through the rotating spindle for the solenoid valve driving the telescopic cylinder 24 and other electrical components. This avoids the potential for external cables to become tangled, knotted, or even broken during rotation, improving the reliability and safety of the machine tool.

[0057] In an optional example, please refer to Figures 1 to 8As shown, a groove 402 is provided on one end of the rotating base 4 facing the direction close to the rotating table 3. The first cutter 5 is disposed in the groove 402. A side through groove 403 is provided on one side of the groove 402 facing the direction close to the rotating arm 6, which extends into the mounting cavity 401. A side bearing 29 is inserted and fixed in the side through groove 403 by interference fit. The first driven end 8 is inserted and fixed in the side bearing 29. A first bearing seat 30 is fixed on the other side of the groove 402 by bolt connection. The other end of the cutter spindle 51 is inserted and fixed in the first bearing seat 30 by bearing connection. A side end plate 46 for sealing the side through groove 403 is fixed on one end of the rotating base 4 facing away from the rotating arm 6.

[0058] Specifically, in this example, the groove 402 at the lower end of the rotating base 4 accommodates the first tool 5 entirely within the rotating base 4, reducing the vertical extension of the milling module, making the overall structure more compact, and improving the structural rigidity of the rotating base 4. Furthermore, the tool spindle 51 of the first tool 5 is supported at both ends by side bearing 29 and side bearing 45 respectively, further improving the structural rigidity of the tool spindle 51, ensuring the flatness and roughness of the machined surface, and avoiding bearing overload and premature failure caused by excessive deformation of the tool spindle 51.

[0059] In an optional example, please refer to Figures 1 to 10 As shown, the rotating base 4 has a rotating groove 404 at one end facing away from the groove 402. The rotating arm 6 is rotatably inserted into the rotating groove 404. The rotating arm 6 has a rotating cavity 601. The end of the rotating arm 6 facing near the rotating groove 404 is fixedly connected to the first rotating shaft 32 by a bearing. The second driven end 10 is fixed to the end of the first rotating shaft 32 facing near the rotating groove 404. The end of the first rotating shaft 32 facing away from the rotating groove 404 extends into the rotating cavity 601 and is fixedly fitted with the first bevel gear 33 by a key connection. The outer wall of the rotating arm 6 is installed with the second rotating shaft 34 by a bearing connection. One end of the second rotating shaft 34 extends into the rotating cavity 601 and is fixedly fitted with the second bevel gear 35 by a key connection. The first bevel gear 33 and the second bevel gear 35 mesh. The other end of the second rotating shaft 34 is fixedly connected to the tool base 36. The second tool 9 is fixedly connected to the tool base 36. Among them, the outer wall of the rotating arm 6 has an arm groove 1 that extends into the rotating cavity 601 at one end facing the direction close to the mounting cavity 401. The arm shell end plate 37 is fixed in the arm groove 1 by bolt connection. The first rotating shaft 32 is inserted into the arm shell end plate 37 by bearing connection. The outer wall of the rotating arm 6 has an arm groove 2 that extends into the rotating cavity 601. The arm shell end plate 38 is fixed in the arm groove 2 by bolt connection. The second rotating shaft 34 is inserted into the arm shell end plate 38 by bearing connection.

[0060] Specifically, this example converts the horizontal rotational power input from the driven spindle 13 along the length of the rotating base 4 into a rotational power output perpendicular to the length of the rotating arm 6 through the meshing of the first bevel gear 33 and the second bevel gear 35. This achieves the reversal of the driving force. The structure is compact, and the relative positional relationship between the first bevel gear 33 and the second bevel gear 35 is guaranteed by the housing of the rotating arm 6 itself and is independent of the swing angle of the rotating arm 6. Regardless of whether the rotating arm 6 is in a horizontal position, a vertical position, or any tilt angle, the internal bevel gear pair always maintains a constant meshing state and meshing accuracy, ensuring that the second tool 9 can obtain stable and reliable power output at various angles.

[0061] In an optional example, please refer to Figures 1 to 12 As shown, a detachable tool shank 92 is bolted into the tool base 36. The head of the tool shank 92 is provided with a tool head 93. Several second tool grooves 94 are opened on the outer wall of the tool head 93. The second blade 91 is fixed in the second tool grooves 94 by bolting.

[0062] Specifically, in this example, the second tool 9 adopts a separate design of tool base 36 and tool holder 92. The tool holder 92 is quickly inserted and fixed in the tool base 36 by locking screws, which realizes the quick replacement of tool holders 92 of different specifications, saving the manufacturing cost and operating cost of the equipment.

[0063] In an optional example, please refer to Figures 1 to 12 As shown, a driven gear ring 39 is bolted to one end of the rotating arm 6 facing the direction near the rotating groove 404. A gear section 405 is provided inside the rotating groove 404, and a rotating gear 42 is provided inside the gear section 405. A side end plate 40 is bolted to one end of the rotating base 4 facing the rotating groove 404. The side end plate 40 is used to seal the rotating groove 404. A rotating motor 41 is bolted to the side end plate 40. The rotating gear 42 is keyed and fixed to the output shaft of the rotating motor 41. The rotating motor 41 is electrically connected to the conductive slip ring 28 via a circuit.

[0064] Specifically, in this example, the meshing of the rotating gear 42 with the driven gear ring 39 drives the rotating arm 6 to rotate precisely, ensuring the angular accuracy of the second tool 9 in precision machining such as chamfering, inclined hole drilling and milling, and inclined plane milling, thereby improving the machining accuracy of the workpiece.

[0065] In an optional example, please refer to Figures 1 to 12As shown, the rotating base 4 includes a base body 406 and a base end plate 407 that are fixedly connected to each other by bolts. A base groove 4061 is formed on the base body 406. The base end plate 407 is fixed to the end of the base groove 4061 and seals the base groove 4061 to form an installation cavity 401. A top groove 4062 is formed on the top of the base body 406. A top bearing 43 is inserted and fixed in the top groove 4062. A shaft through groove 4063 penetrating the base body 406 is formed at the bottom of the top groove 4062. The power spindle 7 is inserted into the top bearing 43, passes through the shaft through groove 4063, and extends into the base groove 4061. An upper end plate 44 is fixed to the top of the base body 406 by bolts. The upper end plate 44 is used to seal the top groove 4062.

[0066] A side through groove 4064 is provided at one end of the base body 406 away from the rotating arm 6. A side bearing 45 is inserted into the side through groove 4064. A side end plate 50 is fixed to the base body 406 by bolts. The side end plate 50 is used to seal the side through groove 4064.

[0067] Internal bearings 47 (first), 48 (second), and 49 (third) are fixed within the base groove 4061. One end of the first driven shaft 16 is inserted into internal bearing 47, and the other end is inserted into side bearing 45. One end of the second driven shaft 17 is inserted into internal bearing 48, and the other end is inserted into internal bearing 49. The top bearing 43, side bearing 45, internal bearings 47, 48, and 49 are positioned and fixed using their respective independent grooves or through slots, and the mounting reference surface of each bearing is machined independently.

[0068] Specifically, the rotating base 4 in this example is formed by bolting together a base body 406 and a base end plate 407. The split design allows the components inside the mounting cavity 401 to be installed and adjusted in position with the base groove 4061 completely open. After the internal components are assembled, the base end plate 407 is closed, avoiding the problem of limited space and difficult assembly. This improves the assembly efficiency and accuracy of the milling module. Furthermore, the power spindle 7, the first driven shaft 16, the second driven shaft 17, and the driven spindle 13 all have independent bearing support structures. Before final assembly, each shaft system can be assembled and tested as an independent sub-assembly, which facilitates quick location and maintenance in case of failure.

[0069] In an optional example, please refer to Figures 1 to 12 As shown, the first cutting tool 5 includes a cutting tool body, and a plurality of first cutting grooves 54 are provided on the outer wall of the cutting tool body. The first cutting blade 52 is fixed in the first cutting grooves 54 by means of bolt connection.

[0070] Specifically, this example achieves rapid replacement of the first blade 52 through the cooperation of the first tool groove 54 and the first blade 52, thereby improving the workpiece processing efficiency.

[0071] In summary, the first cutting tool 5 in this invention has strong structural rigidity and excellent torsional resistance, enabling it to withstand heavy-duty milling under large cutting parameters, ensuring the surface roughness and flatness of the machined surface, and improving the processing efficiency of the horizontal milling machine. Simultaneously, by utilizing the combination of the rotating arm 6, the driven assembly, and the second cutting tool 9, it is possible to perform chamfering, inclined hole drilling and milling, inclined surface milling, and T-slot machining on the workpiece from multiple angles, achieving high-precision cutting of the workpiece, avoiding workpiece disassembly and positioning, and improving processing efficiency. Furthermore, through the sliding of the driven spindle 13, the power is switched between the first cutting tool 5 and the second cutting tool 9, avoiding power loss, ensuring the rotational speed of the first cutting tool 5 and the second cutting tool 9, suppressing cutting vibration caused by the synchronous rotation of the first cutting tool 5 and the second cutting tool 9, and improving the flatness and roughness of the machined surface.
