Description

Technical Field

[0001] This invention belongs to the field of drilling and milling machine tool technology, specifically relating to a multi-station drilling and milling machine tool. Background Technology

[0002] Milling and drilling machines are composite machining equipment that combines drilling with milling functions. They are widely used in the field of mechanical processing. Through drilling, milling, reaming, tapping and other processes, they can complete the machining of complex surfaces such as planes, steps, inclined planes, grooves, shaped surfaces, gears and cut-offs. CNC milling and drilling machines support composite machining such as boring and reaming, and are suitable for the manufacturing of precision parts such as three-dimensional curved surfaces and punch dies. They are one of the most widely used equipment for processing modern mechanical parts.

[0003] Most existing drilling and milling machine tools are single-station or fixed-angle multi-station designs, with limited angle adjustment of the side machining mechanism. This makes it impossible to achieve independent, multi-angle, synchronous machining by multiple sets of tools. For workpieces requiring multi-face and multi-angle drilling and milling, frequent tooling changes and equipment parameter adjustments are necessary, sometimes requiring multiple machines to work together, resulting in cumbersome and inefficient operation. Furthermore, the side machining mechanism of traditional multi-station drilling and milling machine tools lacks effective support and linkage limiting structures. During drilling and milling, tool vibration and uneven force on the mechanism can easily lead to angle deviation. When multiple sets of tools work synchronously, angle consistency is difficult to guarantee, resulting in large positioning errors and affecting machining accuracy. At the same time, most existing drilling and milling machine tools only have single-direction (side or top) machining functions. If drilling and milling of the top and side of the workpiece needs to be completed simultaneously, secondary clamping and positioning are required, which not only increases the number of operation steps but also easily introduces errors due to repeated positioning, reducing machining accuracy and efficiency. Moreover, the waste generated during drilling and milling easily accumulates in the machining area and on the inner wall of the equipment. Existing equipment mostly relies on manual cleaning, requiring frequent machine stops, affecting the continuity of processing and reducing work efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a multi-station drilling and milling machine tool.

[0005] The technical solution adopted to solve the above-mentioned technical problems is as follows: a multi-station drilling and milling machine tool, including a machine tool compartment and an L-shaped top cover installed at one end of the machine tool compartment. A funnel compartment is installed on the inner top of the machine tool compartment. A drawer-type collection compartment located below the funnel compartment is inserted at the bottom of the end of the machine tool compartment away from the L-shaped top cover. Four sets of tilt adjustment mechanisms are evenly arranged on the top of the machine tool compartment, and a first drilling and milling mechanism for side drilling and milling is provided on the tilt adjustment mechanism. A stabilizing mechanism that cooperates with the tilt adjustment mechanism is provided on the inner top of the L-shaped top cover. A linkage mechanism that cooperates with the stabilizing mechanism is provided at the middle position of the inner top of the L-shaped top cover. A second drilling and milling mechanism for drilling and milling directly above is provided at the bottom of the linkage mechanism. A machining table mechanism for placing workpieces is provided inside the funnel compartment. A cleaning mechanism for cleaning the inner wall of the funnel compartment is provided at the bottom of the machining table mechanism.

[0006] Furthermore, the tilt adjustment mechanism includes a fixed base, and four sets of fixed bases are symmetrically distributed on the top of the machine tool compartment with the funnel compartment as the axis. One end of the top of the fixed base near the center of the funnel compartment is hinged to a mounting frame through a hinge plate. The two sides of the top of the fixed base away from the mounting frame are symmetrically hinged to first electric push rods, and the top ends of the two sets of first electric push rods are respectively hinged to the middle position of the two sides inside the mounting frame.

[0007] Through the above technical solution, the mounting frame is hinged to the top of the fixed seat via a hinge plate, forming the core node of the flipping motion. Two sets of first electric push rods are symmetrically hinged to the end of the fixed seat away from the mounting frame, and their top ends are hinged to the inner sides of the mounting frame. Through the extension and retraction of the first electric push rods, the mounting frame is driven to flip around the hinge plate as the axis, thereby adjusting the tilt angle of the mounting frame. The four sets of mechanisms can independently control the extension and retraction amount to achieve different tilt states, which facilitates subsequent drilling and milling processing on the drilling and milling structure of the mounting frame.

[0008] Furthermore, the first drilling and milling mechanism includes a second electric push rod located at the top of the mounting bracket. The end of the mounting bracket away from the first electric push rod is slidably provided with a mounting seat via a pair of first slide rods. A first drive motor is installed inside the mounting seat, and a first cutting tool is installed at the output end of the first drive motor. A strip-shaped through hole is opened at the middle position of the mounting bracket near the mounting seat. The output end of the second electric push rod extends into the mounting bracket and is provided with a connecting block that passes through the strip-shaped through hole and is fixedly connected to the mounting seat.

[0009] Through the above technical solution, the strip-shaped through hole provides clearance space for the movement of the connecting block. When the second electric push rod extends or retracts, it drives the mounting base to move along the axis of the first slide rod, adjusting the distance between the first drive motor and the first tool and the workpiece. After the first drive motor starts, it drives the first tool to rotate at high speed. The first tool performs drilling and milling operations on the side of the workpiece, realizing precise feed and rotational machining of the side tool. With the angle adjustment of the tilt adjustment mechanism, drilling and milling operations at different positions and angles on the side of the workpiece can be accurately completed.

[0010] Furthermore, the stabilizing mechanism includes a second slide bar, of which four pairs are provided, and the four pairs of second slide bars are evenly distributed on the inner top of the L-shaped top cover. The four pairs of second slide bars are symmetrical about the funnel chamber as the axis. Each pair of second slide bars is fitted with a liftable first lifting seat. Side grooves are symmetrically opened on both sides of the bottom of one end of the first lifting seat. First connecting rods are symmetrically hinged in the two sets of side grooves. The ends of the two sets of first connecting rods away from the first lifting seat are respectively hinged to the top of both sides of the mounting frame. A connecting ring is installed at the bottom of the four pairs of second slide bars. The distance between the two sets of first connecting rods is greater than the width of the mounting seat.

[0011] Through the above technical solution, the first connecting rod is hinged in the side grooves on both sides of the bottom of the first lifting seat, and its other end is hinged to the top of both sides of the mounting frame to form a linkage support structure. When the mounting frame is flipped, the first lifting seat is pulled up and down synchronously along the second slide rod through the first connecting rod, which provides vertical limiting support and force distribution for the mounting frame, effectively offsetting the force generated by drilling and milling vibration, and preventing the mounting frame from shifting or shaking. The connecting ring is fixed to the bottom of the four pairs of second slide rods to enhance the overall rigidity of the slide rods. The distance between the two sets of first connecting rods is greater than the width of the mounting seat to avoid motion interference.

[0012] Furthermore, the linkage mechanism includes a first square tube located at the top center of the L-shaped top cover. A second lifting seat is sleeved on the outside of the first square tube. A return spring is sleeved on the top of the outside of the first square tube, and the top and bottom of the return spring are fixedly connected to the L-shaped top cover and the second lifting seat, respectively. Slots are symmetrically opened on the four sides of the second lifting seat. A sliding insertion hole is opened at one end of the first lifting seat near the second lifting seat, extending to the other end of the second lifting seat. An L-shaped insert rod that cooperates with the slot is inserted into the opening at the end of the sliding insertion hole away from the second lifting seat. A third electric push rod is installed on the top of the first lifting seat, and the output end of the third electric push rod is fixedly connected to the outside of the L-shaped insert rod.

[0013] Through the above technical solution, a reset spring is sleeved on the top of the first square tube, with its two ends connected to the L-shaped top cover and the second lifting seat respectively, providing reset elasticity. A sliding insertion hole is opened at the end of the first lifting seat near the second lifting seat, and the L-shaped insertion rod is inserted into the sliding insertion hole. The third electric push rod is fixed to the top of the first lifting seat, and its output end is fixed to the outside of the L-shaped insertion rod, driving the L-shaped insertion rod to move along the sliding insertion hole, realizing the insertion and removal cooperation with the slot on the side of the second lifting seat, thereby locking or unlocking the linkage relationship between the first lifting seat and the second lifting seat, realizing the synchronous linkage or independent action switching of the four sets of first lifting seats.

[0014] Furthermore, a stop plate is installed at the middle position of the bottom of the first lifting seat near the end of the second lifting seat, and the end of the L-shaped rod near the first lifting seat is provided with a beveled surface.

[0015] With the above technical solution, the abutment is installed at the bottom of the first lifting seat near the end of the second lifting seat. In the initial state, it abuts against the top of the second lifting seat to ensure that the L-shaped plug is aligned with the axis of the slot. The end of the L-shaped plug near the first lifting seat is provided with a beveled surface to reduce the frictional resistance with the inner wall of the slot during insertion and removal, making the insertion and removal action smoother and reducing mechanical wear.

[0016] Furthermore, the second drilling and milling mechanism includes a second square tube sleeved on the outside of the first square tube, the top of the second square tube being fixedly connected to the bottom of the second lifting seat, a third square tube sleeved on the outside of the second square tube, and a U-shaped frame installed at the bottom end of the third square tube, a limiting slide rod inserted inside the first square tube, the bottom end of the limiting slide rod being fixedly connected to the middle position of the top of the U-shaped frame, a second drive motor installed inside the U-shaped frame, and a second cutting tool installed at the output end of the second drive motor, and fourth electric push rods symmetrically installed at the two corners of the bottom of the second lifting seat, the output ends of both sets of fourth electric push rods being fixedly connected to the top of the outside of the third square tube.

[0017] Through the above technical solution, the top of the second square tube is fixed to the bottom of the second lifting seat and rises and falls synchronously with the second lifting seat. The third square tube is sleeved on the outside of the second square tube. The U-shaped frame is fixed to the bottom of the third square tube. The limiting slide rod is inserted into the inside of the first square tube, and its bottom end is fixed to the top of the U-shaped frame to provide guidance for the lifting and lowering of the U-shaped frame. Two sets of fourth electric push rods are symmetrically installed at the two bottom corners of the second lifting seat. The output end is fixed to the top of the outside of the third square tube and drives the third square tube to rise and fall along the second square tube. The second drive motor is installed inside the U-shaped frame, and its output end drives the second cutter to rotate to complete the top drilling and milling.

[0018] Furthermore, the processing table mechanism includes a frustum-shaped hollow chamber located inside the funnel chamber. The central axis of the frustum-shaped hollow chamber is on the same straight line as the central axis of the funnel chamber. The top of the outer side of the frustum-shaped hollow chamber is fixedly connected to the bottom of four sets of fixed seats through four sets of connecting frames. Three sets of hydraulic cylinders are evenly installed on the inner wall of the frustum-shaped hollow chamber, and the output ends of the three sets of hydraulic cylinders are jointly mounted on a mounting platform. A first servo motor is installed at the center of the bottom of the mounting platform. The output shaft of the first servo motor extends to the top of the mounting platform and is mounted on a circular processing table. A fixing fixture for fixing the workpiece is provided on the top of the circular processing table.

[0019] Through the above technical solution, the frustum-shaped hollow chamber is fixed to the bottom of four sets of connecting frames and four sets of fixed seats. Its central axis coincides with the funnel chamber, providing stable support. Three sets of hydraulic cylinders are evenly installed on the inner wall of the frustum-shaped hollow chamber, and their output ends are connected to the mounting platform. The mounting platform is raised and lowered by the extension and retraction of the hydraulic cylinders to adjust the height of the workpiece. The first servo motor is installed at the bottom center of the mounting platform, and its output shaft extends to the top of the mounting platform and connects to the circular processing table. The fixed fixture is placed on the top of the circular processing table to clamp the workpiece. After the first servo motor is started, it drives the circular processing table to rotate, adjusting the circumferential position of the workpiece, realizing the height adjustment and precise circumferential positioning of the workpiece, adapting to the fixing requirements of workpieces of different sizes. The relative position of the workpiece and the tool can be adjusted by rotation, easily completing the processing of side annular distributed holes, grooves, etc. The positioning is accurate and the clamping is stable, providing reliable guarantee for multi-directional and multi-position processing.

[0020] Furthermore, two sets of threaded posts are installed at the bottom of the fixed base near the funnel chamber, and two sets of fixing holes adapted to the threaded posts are opened on the top of the connecting frame. The threaded posts pass through the fixing holes and are threaded with fixing nuts. The top of the connecting frame is fixedly connected to the bottom of the fixed base through the threaded posts, fixing holes and fixing nuts.

[0021] Through the above technical solution, the threaded column passes through the fixing hole and is locked by the fixing nut, realizing the detachable fixed connection between the connecting frame and the fixed seat. This facilitates installation, disassembly and maintenance, ensures the firmness of the connection between the frustum-shaped hollow chamber and the fixed seat, avoids vibration or displacement caused by loose connection during processing, ensures processing stability, and the detachable design reduces the difficulty of equipment assembly and maintenance, and improves maintenance convenience.

[0022] Furthermore, the cleaning mechanism includes a connecting bearing located at the top of the inner wall of the funnel chamber. Three sets of inclined rods close to the inner wall of the funnel chamber are evenly installed on the inner ring of the connecting bearing, and a cleaning brush close to the inner wall of the funnel chamber is installed on one side of the inclined rod. A second servo motor is installed at the center of the bottom of the frustum-shaped hollow chamber. The output shaft of the second servo motor extends to the bottom of the frustum-shaped hollow chamber and a rotating disk is installed thereon. The bottom of the three sets of inclined rods is fixedly connected to the outer side of the rotating disk through a second connecting rod.

[0023] Through the above technical solution, the second servo motor drives the rotating disk to rotate, and the second connecting rod drives the inclined rod and cleaning brush to rotate synchronously, cleaning the waste on the inner wall of the funnel chamber. The waste falls into the drawer-type collection chamber along the guide of the funnel chamber, realizing the automated cleaning of waste during the processing, avoiding the accumulation of waste that affects the processing accuracy or damages equipment parts, eliminating the need for real-time manual cleaning, reducing downtime, and improving processing continuity and overall operation efficiency.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention can independently or synchronously adjust the angle by using four sets of tilt adjustment mechanisms in conjunction with the first drilling and milling mechanism, so that the side-position tools can be processed synchronously at different angles or batched at a uniform angle. In addition, with the processing table mechanism, there is no need to frequently change equipment or adjust tooling, which can easily adapt to the multi-angle and multi-position processing needs of workpieces of different specifications. Moreover, the four sets of workstations can be operated synchronously, which greatly improves the processing efficiency. (2) The present invention provides vertical limit and force distribution support through the stabilizing mechanism to avoid deviation caused by drilling and milling vibration. In addition, with the linkage mechanism, each guide and limit component ensures the consistency of the tool tilt angle, effectively reducing positioning error and improving processing accuracy. (3) The present invention integrates the top and side drilling and milling mechanisms by designing a second drilling and milling mechanism at the bottom of the linkage mechanism to complete composite processing in a coordinated manner, further improving the applicability of the drilling and milling machine. (4) The present invention has a built-in automated waste cleaning system. The rotating cleaning brush is combined with the funnel bin guide, and the waste is automatically collected into the drawer-type bin. There is no need for manual real-time cleaning, which reduces maintenance costs and improves overall operating efficiency. Attached Figure Description

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0044] like Figures 1-8As shown, a multi-station drilling and milling machine tool of this embodiment includes a machine tool compartment 1 and an L-shaped top cover 11 installed at one end of the machine tool compartment 1. Four sets of tilt adjustment mechanisms 2 are evenly arranged on the top of the machine tool compartment 1, and a first drilling and milling mechanism 3 for lateral drilling and milling is provided on the tilt adjustment mechanism 2. The tilt adjustment mechanism 2 includes a fixed base 201. The four sets of fixed bases 201 are symmetrically distributed on the top of the machine tool compartment 1 with the funnel compartment 9 as the axis, ensuring that the mechanism is firmly installed, avoiding displacement caused by drilling and milling vibration, and providing stable support for subsequent angle adjustment. One end of the top of the fixed base 201 near the center position of the funnel compartment 9 is hinged to a mounting bracket 203 through a hinge plate 202, realizing the flip-out connection between the mounting bracket 203 and the fixed base 201. Next, the mounting bracket 203 provides a mounting carrier for the first drilling and milling mechanism 3. The tool angle can be adjusted by flipping to adapt to different machining requirements. The top of the fixed base 201, away from the end of the mounting bracket 203, is symmetrically hinged with two first electric push rods 204. The tops of the two sets of first electric push rods 204 are respectively hinged to the middle positions of the two sides inside the mounting bracket 203, providing a power source for angle adjustment. The two sets of symmetrical designs ensure balanced force on the mounting bracket, smooth flipping, and precise control of the tilt angle. The first drilling and milling mechanism 3 includes a second electric push rod 307 located at the top of the mounting bracket 203, providing a power source for tool feed. The extension and retraction stroke is precise, ensuring controllable adjustment of the distance between the tool and the workpiece. The mounting bracket 203 is located away from the first electric push rod 307. One end of the push rod 204 is slidably mounted on a mounting base 301 via a pair of first slide rods 304, achieving integrated mounting of the drive motor and the cutting tool. This drives the cutting tool to feed synchronously, ensuring consistent movement. The first slide rods 304 restrict the movement trajectory of the mounting base 301, ensuring smooth axial movement and preventing offset that could lead to machining errors. A first drive motor 302 is installed inside the mounting base 301, and a first cutting tool 303 is mounted at the output end of the first drive motor 302. The first drive motor 302 provides cutting power for the drilling and milling operation, while the first cutting tool 303 is the cutting component that directly acts on the workpiece. Combined with angle adjustment and feed action, it precisely completes side drilling and milling. The mounting bracket 203 is located close to the mounting base 301. A strip-shaped through hole 305 is provided at the middle position of the end. The output end of the second electric push rod 307 extends into the mounting bracket 203 and is equipped with a connecting block 306 that passes through the strip-shaped through hole 305 and is fixedly connected to the mounting base 301. This realizes the power connection between the second electric push rod and the mounting base. The connection is firm and the power transmission is lossless. The strip-shaped through hole 305 can prevent the connecting block 306 from interfering with the mounting bracket 203, ensuring that the second electric push rod 307 drives the mounting base 301 to move smoothly. This enables multi-angle and precise machining of the side tool. The four sets of mechanisms can operate independently or synchronously. They can adapt to the machining needs of different angles and positions of the workpiece side without changing the tooling, significantly improving machining flexibility and accuracy.

[0045] like Figures 9-13As shown, the inner top of the L-shaped top cover 11 in this embodiment is provided with a stabilizing mechanism 4 that cooperates with the tilt adjustment mechanism 2. A linkage mechanism 5 that cooperates with the stabilizing mechanism 4 is provided at the middle position of the inner top of the L-shaped top cover 11. The stabilizing mechanism 4 includes a second slide rod 401, of which four pairs are provided, and the four pairs of second slide rods 401 are evenly distributed on the inner top of the L-shaped top cover 11. The four pairs of second slide rods 401 are symmetrical about the funnel chamber 9 as the axis. Each pair of second slide rods 401 is fitted with a liftable first lifting seat 402. The first lifting seat 402 is linked to the mounting frame 203 and rises and falls synchronously with the rotation of the mounting frame 203, distributing the force on the mechanism. During the process, the second slide rods 401 restrict the movement of the first lifting seat 402. To ensure smooth vertical lifting and lowering without tilting, the bottom of the first lifting seat 402 is symmetrically provided with side grooves 403 on both sides. Two sets of first connecting rods 404 are symmetrically hinged within the two sets of side grooves 403. The ends of the two sets of first connecting rods 404 away from the first lifting seat 402 are respectively hinged to the top of both sides of the mounting frame 203. The first connecting rods 404 enable the linkage between the stabilizing mechanism and the tilting adjustment mechanism, dispersing the force of drilling and milling vibration and improving the stability of the mechanism. The side grooves 403 prevent interference between the first connecting rods 404 and the first lifting seat 402, ensuring flexible rotation of the hinge points. Connecting rings 405 are installed at the bottom of the four pairs of second sliding rods 401 to enhance the overall rigidity of the second sliding rods 401, preventing deformation of a single sliding rod under stress and ensuring... Multiple sets of first lifting seats 402 move in unison. The distance between two sets of first connecting rods 404 is greater than the width of the mounting base 301 to avoid movement interference. The linkage mechanism 5 includes a first square tube 501 located at the top center of the L-shaped top cover 11. A second lifting seat 502 is sleeved on the outside of the first square tube 501. As the core component of the linkage, it achieves synchronous or independent action switching by locking / unlocking with the four sets of first lifting seats 402. The first square tube 501 restricts the movement trajectory of the second lifting seat 502 to ensure its smooth vertical lifting and lowering, ensuring positioning accuracy. A return spring 503 is sleeved on the top of the outside of the first square tube 501, and the top and bottom of the return spring 503 are respectively connected to the L-shaped top cover 11 and the second lifting seat 502. 2. Fixed connection: After the linkage unlocks, pull the second lifting seat 502 back to its initial position to prepare for the next linkage lock. The second lifting seat 502 has slots 504 symmetrically opened on its four sides. The first lifting seat 402 has a sliding insertion hole 505 extending to the other end of the second lifting seat 502 at one end near the second lifting seat 502. An L-shaped insertion rod 506, cooperating with the slot 504, is inserted into the opening of the sliding insertion hole 505 at the end away from the second lifting seat 502. The sliding insertion hole 505 restricts the movement direction of the L-shaped insertion rod 506, ensuring smooth insertion and removal in a horizontal direction and preventing deviation. The slot 504 and the L-shaped insertion rod 506 form a linkage locking mechanism, realizing the locking / unlocking of the first lifting seat 402 and the second lifting seat 502.A third electric push rod 507 is installed on the top of the first lifting seat 402, and the output end of the third electric push rod 507 is fixedly connected to the outer side of the L-shaped plug 506, providing the power source for the insertion and removal of the L-shaped plug 506. This ensures precise extension and retraction, guaranteeing timely locking / unlocking actions. A stop plate 508 is installed at the middle position of the bottom of the first lifting seat 402 near the end of the second lifting seat 502, ensuring that the first and second lifting seats 402 are initially aligned and that the L-shaped plug 506 is precisely aligned with the slot 504. The end of the L-shaped plug 506 near the first lifting seat 402 has a beveled surface. This beveled surface design reduces insertion and removal friction, ensuring smooth insertion.

[0046] like Figure 9 and Figures 12-13 As shown, the bottom of the linkage mechanism 5 in this embodiment is provided with a second drilling and milling mechanism 6 for drilling and milling directly above. The second drilling and milling mechanism 6 includes a second square tube 601 sleeved on the outside of the first square tube 501. The top of the second square tube 601 is fixedly connected to the bottom of the second lifting seat 502, providing a base for the sleeved installation of the third square tube 602, driving the entire second drilling and milling mechanism 6 to rise and fall synchronously with the linkage mechanism 5. The third square tube 602 is sleeved on the outside of the second square tube 601, realizing the secondary lifting and adjustment of the U-shaped frame 603 and the tool, accurately controlling the distance between the tool and the top of the workpiece. The bottom end of the third square tube 602 is equipped with a U-shaped frame 603, realizing the integrated installation of the drive motor and the tool, ensuring the stable installation of the components. The first square tube 501 has limited insertion space inside. The bottom end of the limiting slide bar 604 is fixedly connected to the middle position of the top of the U-shaped frame 603, limiting the movement trajectory of the U-shaped frame 603 and preventing it from tilting during lifting and lowering, thus ensuring vertical feed of the tool. The U-shaped frame 603 is equipped with a second drive motor 605, and the output end of the second drive motor 605 is equipped with a second tool 606. The second drive motor 605 drives the second tool 606 to rotate, thereby performing drilling and milling on the workpiece. The bottom corners of the second lifting seat 502 are symmetrically equipped with fourth electric push rods 607. The output ends of both sets of fourth electric push rods 607 are fixedly connected to the top of the outer side of the third triangular tube 602, providing a power source for secondary feed of the tool. The two sets of symmetrical design ensure that the third triangular tube 602 is subjected to balanced force and the lifting and lowering is smooth.

[0047] like Figures 1-5 and Figures 14-17As shown, in this embodiment, a funnel-shaped chamber 9 is installed on the inner top of the machine tool compartment 1. A drawer-type collection compartment 10 located below the funnel-shaped chamber 9 is inserted into the bottom of the machine tool compartment 1 at the end away from the L-shaped top cover 11. A processing table mechanism 7 for placing workpieces is provided inside the funnel-shaped chamber 9. A cleaning mechanism 8 for cleaning the inner wall of the funnel-shaped chamber 9 is provided at the bottom of the processing table mechanism 7. The processing table mechanism 7 includes a frustum-shaped hollow chamber 705 located inside the funnel-shaped chamber 9. The frustum-shaped hollow chamber 705 is on the same straight line as the central axis of the funnel-shaped chamber 9, providing overall support for the processing table mechanism 7. The hollow design inside facilitates the accommodation of the drive components. The top of the frustum-shaped hollow chamber 705 is fixedly connected to the bottom of four sets of fixed seats 201 through four sets of connecting brackets 706, respectively, to realize the processing. The robust connection between the platform mechanism and the tilt adjustment mechanism ensures overall stability during processing. Two sets of threaded posts are installed at the bottom of the fixed base 201 near the funnel chamber 9. Two sets of fixing holes, matching the threaded posts, are opened at the top of the connecting frame 706. The threaded posts pass through the fixing holes and are threaded with fixing nuts. The top of the connecting frame 706 is fixedly connected to the bottom of the fixed base 201 via the threaded posts, fixing holes, and fixing nuts, ensuring a secure connection between the connecting frame and the fixed base. This also facilitates disassembly and maintenance, reducing maintenance difficulty. Three sets of hydraulic cylinders 707 are evenly installed on the inner wall of the frustum-shaped hollow chamber 705, and the output ends of the three sets of hydraulic cylinders 707 are all mounted on the mounting platform 701. The hydraulic cylinders 707 provide the power source for the lifting and lowering of the mounting platform 701. The telescopic mechanism ensures smooth lifting and lowering of the mounting platform, enabling height adjustment of the workpiece-bearing components and providing suitable installation space for workpieces of different sizes. A first servo motor 702 is installed at the center of the bottom of the mounting platform 701. The output shaft of the first servo motor 702 extends above the mounting platform 701 and is mounted on a circular machining table 703, providing a platform for placing the workpiece. The relative position of the workpiece and the tool can be adjusted by rotation, adapting to multi-position machining. The top of the circular machining table 703 is equipped with a fixing clamp 704 for fixing the workpiece, ensuring that the workpiece is firmly fixed during machining, avoiding displacement caused by vibration, and ensuring machining accuracy. The cleaning mechanism 8 includes a connecting bearing 801 located at the top of the inner wall of the funnel chamber 9, reducing frictional resistance when the inclined rod 802 rotates. To ensure smooth rotation, three sets of inclined rods 802 are evenly installed on the inner ring of the connecting bearing 801, close to the inner wall of the funnel chamber 9. A cleaning brush 803, also close to the inner wall of the funnel chamber 9, is installed on one side of each inclined rod 802. The inclined rods 802 drive the cleaning brush 803 to rotate synchronously, achieving comprehensive cleaning of the funnel chamber's inner wall without any blind spots. A second servo motor 804 is installed at the center of the bottom of the frustum-shaped hollow chamber 705. The output shaft of the second servo motor 804 extends to the bottom of the frustum-shaped hollow chamber 705 and is fitted with a rotating disk 805. The second servo motor 804 drives the rotating disk 805 to rotate, which in turn drives the synchronous rotation of multiple sets of inclined rods 802, ensuring consistent movement of the cleaning brush 803 and improving the cleaning effect.The bottoms of all three sets of diagonal bars 802 are fixedly connected to the outer side of the rotating disk 805 via the second connecting rod 806, achieving power transmission. The connection is secure, ensuring that the rotating disk 805 synchronously drives the diagonal bars 802 when it rotates.

[0048] The working principle of this embodiment is as follows: Before use, the hydraulic cylinder 707 is extended to raise the mounting platform 701 inside the funnel chamber 9. Then, the workpiece to be processed is placed on the circular processing table 703 and fixed by the fixing fixture 704. Next, the mounting platform 701 is lowered to the specified height, and the first electric push rod 204 is shortened according to the drilling and milling angle requirements of the side of the workpiece. At this time, the mounting frame 203 gradually tilts from its original state of being perpendicular to the top of the fixed seat 201. Then, the second electric push rod 307 is extended to push the mounting seat 301 to move axially along the first slide rod 304 with the first drive motor 302 and the first tool 303. During the process, the first drive motor 302 is controlled to drive the first tool 303 to rotate. When the top of the first tool 303 contacts the side of the workpiece, it is drilled and milled.

[0049] If the side milling requirements of the workpiece are different, the tilt angles of the four sets of mounting brackets 203 can be controlled (the tilt angles of the four sets of mounting brackets 203 can be different at this time), and the first tools 303 on the four sets of mounting brackets 203 simultaneously perform milling on the workpiece (the drilling and milling angles of the four sets of first tools 303 are different).

[0050] If the side of the workpiece needs to be drilled and milled multiple times with the same requirements, when the four sets of mounting brackets 203 are perpendicular to the top of the fixed seat 201 (at this time, the bottom plates 508 of the four sets of first lifting seats 402 are all against the bottom of the second lifting seat 502), the third electric push rods 507 at the top of the four sets of first lifting seats 402 are shortened so that the top of the L-shaped insert rod 506 is inserted into the slot 504 (at this time, the four sets of L-shaped insert rods 506 and the second lifting seat 502 are actually one piece during the lifting process). Then, the four pairs of first electric push rods 204 on the four sets of fixed seats 201 are controlled to extend and retract synchronously so that the tilt angle of each set of mounting brackets 203 remains the same. Then, the first rotating tool 303 performs the drilling and milling process.

[0051] When the first electric push rod 204 shortens, the mounting bracket 203 flips outward around the hinge axis of the hinge plate 202. The mounting bracket 203 pulls the first lifting seat 402 downward on the second slide rod 401 via the first connecting rod 404. The first lifting seat 402 drives the second lifting seat 502 to descend synchronously through the cooperation of the L-shaped insert 506 and the slot 504 (the return spring 503 is stretched by force). The second lifting seat 502 drives the second square tube 601 to slide downward on the first square tube 501. During this process, the second drive motor 605... The second tool 606 descends synchronously. If drilling and milling are required on the top of the workpiece, the fourth electric push rod 607 is extended to allow the third triangular tube 602 to slide downward on the second square tube 601. The third triangular tube 602 drives the second drive motor 605 and the second tool 606 to descend again (during which the U-shaped frame 603 drives the limiting slide rod 604 to slide downward in the first square tube 501). Then, the second drive motor 605 is controlled to drive the second tool 606 to rotate and perform drilling and milling on the top of the workpiece.

[0052] During the entire drilling and milling process, the first servo motor 702 can be controlled to drive the circular machining table 703 to rotate at a specified angle, adjusting the relative position of the side of the workpiece to be processed on the circular machining table 703 and the four sets of first tools 303. At the same time, the second servo motor 804 is controlled to drive the rotating disk 805 to rotate. The rotating disk 805, in conjunction with the second connecting rod 806, drives the three sets of inclined rods 802 to rotate synchronously. The cleaning brush 803 on the inclined rod 802 cleans the waste chips that fall into the inner wall of the funnel chamber 9 during the drilling and milling process, so that these waste chips fall into the drawer-type collection chamber 10 along the guide of the funnel chamber 9. The drawer-type collection chamber 10 is periodically pulled out from the machine tool chamber 1 and the waste chips collected inside are centrally processed.

[0053] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
