Description

Technical Field

[0001] This invention relates to the field of mechanical equipment technology, specifically to a cutting device and method for processing mining machinery parts. Background Technology

[0002] This invention relates to the field of mechanical manufacturing technology, and in particular to a cutting device for processing mining machinery parts and a method for performing the processing using the device.

[0003] Mining machinery parts, such as hydraulic valve bodies, large shafts, and gear blanks, are generally characterized by their large weight, irregular structure, and hard materials. During manufacturing, machining is a crucial process to ensure their dimensional and positional tolerances and assembly accuracy. The machining quality of these parts directly affects the overall reliability and service life of the mining equipment.

[0004] Currently, the machining of such parts is mostly done using general-purpose horizontal lathes, relying on a three-jaw chuck and tailstock for clamping. For large, heavy workpieces, this traditional method has significant drawbacks: First, the workpiece's own weight easily leads to bending deformation and cutting vibration in a cantilevered state, severely restricting machining accuracy and surface quality; second, the excessive clamping force applied to overcome vibration easily creates indentations on the workpiece surface, and may even cause irreversible clamping deformation in thin-walled or irregularly shaped parts, making it difficult to guarantee the yield rate. Furthermore, traditional fixtures lack adaptability to irregular contours (such as blanks with keyways or flanges), making clamping and positioning difficult, requiring long auxiliary times, and unsuitable for flexible production needs involving multiple varieties and small batches.

[0005] While some existing technologies attempt to improve stability through vertical layouts or improved chuck structures, they still fail to fundamentally resolve the inherent contradiction between "high rigidity" and "non-destructive clamping" in fixtures. For example, although the patent with authorization announcement number CN213827317U adopts vertical clamping, its fixture's adaptability to irregularly shaped parts remains limited; while the patent with authorization announcement number CN219379133U focuses on the ease of tool changing, its fixture rigidity and clamping effect on heavy workpieces are still insufficient. More importantly, most existing devices are single-function, failing to integrate functions such as efficient clamping, multi-station collaboration, automated loading and unloading, and waste recycling, resulting in low overall processing efficiency and making it difficult to meet the dual requirements of efficiency and quality in modern mining machinery manufacturing.

[0006] Therefore, given the shortcomings of existing technologies, there is an urgent need for an innovative cutting and machining solution. This solution not only requires a fixture that can intelligently adapt to the shape of the workpiece and possess both flexible envelopment and rigid support capabilities, but also necessitates the construction of a highly efficient production system that integrates multi-station machining, automated logistics, and intelligent control, in order to systematically improve the machining accuracy, production efficiency, and flexibility of mining machinery parts.

[0017] As a preferred technical solution of the present invention, S1: workpiece loading and initialization The workpiece to be processed is transported to the preset position by automatic feeding device A or automatic feeding device B; the automatic part-grabbing head of the cutting device grabs the workpiece under the drive of the automatic part-grabbing cylinder, and transfers and clamps the workpiece on the fixture of cutting station A or cutting station B. S2: Adaptive Flexible Clamping The fixtures at the clamping station perform clamping operations: When cutting station A is used, the internal clamping block drive cylinder drives the internal clamping block to clamp the workpiece from the inside, and the external clamping block works together to complete the centering and fixing of the workpiece. When cutting station B is used, each clamping cylinder drives the flexible clamping head to move radially. After the flexible clamping head contacts the workpiece, its head-shaped contact head undergoes adaptive deformation to conform to the workpiece contour. After the pressure increases, the internal porous sintered skeleton and incompressible hydraulic oil work together to form a rigid support, achieving high rigidity and non-destructive clamping. S3: Multi-axis linkage cutting machining When either rotary drive motor A or rotary drive motor B is started, it drives the clamped workpiece to rotate. At the same time, the Y-axis drive motor and the X-axis moving motor of the cutting device work together to drive the Y-axis moving plate and the X-axis moving plate to move through the threaded transmission rod, thereby driving the cutting tool structure to cut the rotating workpiece according to the preset trajectory. S4: Workpiece Transfer and Temporary Storage When workpiece transfer is required between cutting station A and cutting station B, the automatic pick-up head performs a gripping action to move the workpiece that has completed one process from one station and place it in the workpiece storage area or directly transfer it to another station for clamping. S5: Finished Product Unloading and Collection After processing, the fixture releases the workpiece, the automatic part pick-up head grabs the finished workpiece and releases it to the workpiece collection point; the finished workpiece is discharged from the finished product outlet through the finished product collection device under the drive of gravity or the collection motor, completing the entire processing cycle.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention, by setting up a dual-station structure of cutting station A and cutting station B, and cooperating with automatic loading device A and automatic loading device B, realizes continuous operation of automatic workpiece loading, processing and unloading. The two stations can perform different processes simultaneously, or one station can perform loading and unloading operations while the other station is processing, which significantly reduces equipment idle time and greatly improves production efficiency.

[0019] 2. This invention achieves precise tool positioning through a precision threaded transmission rod. Combined with a flexible, self-adaptive clamping head, it can adapt to the workpiece contour under low pressure and provide rigid support under high pressure, effectively suppressing machining vibrations and ensuring the stability of the machining process, thereby improving machining accuracy and surface quality.

[0020] 3. In this invention, the flexible clamping head is equipped with a porous sintered skeleton and incompressible hydraulic oil inside, and its head-shaped contact head adopts a dense, sealed soft outer shell layer and has a built-in hard alloy ball. This structure allows it to switch between rigid and flexible properties through pressure changes, which can reliably clamp regular workpieces and effectively adapt to the clamping requirements of irregularly shaped and thin-walled parts, significantly expanding the processing range of the equipment.

[0021] 4. In this invention, a workpiece collection area is provided inside the machine tool base, and a finished product collection device is correspondingly configured at the bottom. Chips and finished workpieces generated during processing can be automatically collected and processed by the system. The collection body adopts an inclined structure design, which facilitates material transportation, keeps the working environment clean, reduces manual cleaning, and optimizes the production environment.

[0022] 5. This invention integrates functions such as automatic feeding, multi-station processing, and automatic collection. Through the coordinated control of various drive motors and cylinders, it achieves fully automated processing from raw material to finished product. This reduces the labor intensity and skill requirements of operators, while improving the standardization and consistency of the production process. Attached Figure Description

An X-axis moving plate 74 is movably mounted on the upper end face of the Y-axis moving plate 73. An X-axis moving motor 75 is fixedly mounted on one side of the Y-axis moving plate 73. A threaded transmission rod is also fixedly mounted on one side of the X-axis moving motor 75. The threaded transmission rod is used to drive the X-axis moving plate 74 to reciprocate. The X-axis moving plate 74 includes a cutting base plate 741 movably connected to the Y-axis moving plate 73. A cutting tool structure 744 is fixedly installed on one side of the upper end face of the cutting base plate 741. An automatic part-picking head 745 is fixedly installed on the upper end face of the cutting base plate 741 near the cutting base plate 741. An automatic part-picking cylinder 742 is fixedly installed on one side of the automatic part-picking head 745. A workpiece temporary storage area 743 is also fixedly installed on the upper end face of the cutting base plate 741.

[0027] In this embodiment, the machine tool base 51 serves as the rigid foundation of the entire device. The fixture mounting point 52 and the cutting device mounting point 54 on the machine tool base are precisely installed with cutting stations A1 and B3, and two sets of cutting devices 7, respectively, through bolt fixing, forming a dual-station collaborative machining system. Automatic feeding devices A2 and B6 are fixed to the upper end face and one side of the machine tool base, respectively, realizing automated supply of blanks.

[0028] Specifically, the finished product collection device 4 includes a collection body 43 fixed to the lower end face of the machine tool base 51.

[0030] Specifically, the cutting station A1 includes a fixture frame A12 fixedly installed on the fixture mounting location 52. A rotary drive motor A11 for driving the fixture frame A12 to rotate is fixedly installed on the upper end face of the fixture frame A12. A fixture body A13 is fixedly installed on one side of the fixture frame A12. The fixture body A13 includes a flexible card 132.

[0031] In this embodiment, the cutting station A1 is fixed to the fixture mounting point 52 via the fixture frame A12. The rotation drive motor A11 is connected to the fixture frame A12 via a coupling or reducer, driving the entire fixture to rotate, thereby driving the clamped workpiece to perform turning operations. The fixture body A13 is fixedly connected to the fixture frame A12 via the mounting plate 133. Its unique feature is the use of an internal clamping block 134 driven by an internal clamping block drive cylinder 135, which cooperates with the external clamping block 131 to form a coordinated clamping force. The flexible card 132 provides the necessary tolerance space, enabling the fixture to adapt to workpiece size fluctuations within a certain range, achieving fast and stable centering and clamping, which is particularly suitable for the processing of disc-shaped and sleeve-shaped workpieces.

[0032] Specifically, the cutting station B3 includes a fixture frame B32 fixedly installed on the fixture mounting location 52. A motor mounting plate 34 is fixedly installed on the upper end face of the fixture frame B32. A rotary drive motor B31 is fixedly installed on the upper end face of the motor mounting plate 34. The rotary drive motor B31 is used to drive the fixture frame B32 to rotate. A fixture body B33 is fixedly installed at one end of the fixture frame B32. The fixture body B33 includes a chuck 335 fixedly connected to the fixture frame B32. Several clamping cylinders 332 are arranged around the chuck 335. Fixing blocks 331 are fixedly installed on both sides of each clamping cylinder 332. The chuck 335 is also provided with a sliding groove for cooperating with the clamping cylinder 332. A clamping cylinder sliding slot frame 334 is arranged inside the sliding groove. A flexible clamping head 333 is fixedly installed at one end of the clamping cylinder 332. The flexible clamping head 333 is used to clamp the workpiece.

[0033] In this embodiment, the cutting station B3 is fixed to another fixture mounting point 52 via a fixture frame B32. A rotation drive motor B31 is fixed via a motor mounting plate 34 and drives the fixture frame B32 to rotate. The core of the fixture body B33 lies in its chuck 335 and the flexible fixture head 333 driven by a clamping cylinder 332. The clamping cylinder 332 is positioned by a fixing block 331 and moves radially within the groove of the chuck 335 along the sliding slot frame 334 of the clamping cylinder, achieving synchronous opening and closing of the grippers. The main feature of this station is the use of an advanced flexible fixture head 333, providing a solution for clamping irregularly shaped parts and heavy workpieces.

[0034] Specifically, the flexible clamp head 333 includes an installation interface 3334 fixedly connected to the clamping cylinder 332. An outer cylinder 3333 is fixedly installed on one side of the installation interface 3334. A flexible joint interface 3335 is fixedly installed on one side of the outer cylinder 3333. A head-shaped contact head 3331 is fixedly installed on one side of the flexible joint interface 3335. A porous sintered skeleton 3332 is fixedly installed between the installation interface 3334 and the head-shaped contact head 3331. The porous sintered skeleton 3332 is fixedly installed inside the outer cylinder 3333. The porous sintered skeleton 3332 has multiple layers of frames inside, the head-shaped contact head 3331 is set as a dense sealed soft shell layer, the flexible clamp head 333 is filled with incompressible hydraulic oil, and the head-shaped contact head 3331 has several hard alloy balls inside.

[0035] In this embodiment, the flexible clamping head 333 is fixedly connected to the piston rod end of the clamping cylinder 332 via its mounting interface 3334. Its core innovation lies in the internally encapsulated porous sintered skeleton 3332, which is immersed in incompressible hydraulic oil and sealed within the cavity formed by the outer cylinder 3333 and the head-shaped contact head 3331. When the head-shaped contact head 3331 contacts the workpiece and is pressurized, the pressure is transmitted to the internal hydraulic oil and porous skeleton through the dense, sealed soft outer shell layer. In the low-pressure stage, the system allows for slight deformation to adapt to the workpiece contour; in the high-pressure stage, the internal hard alloy balls and the incompressible oil work together to instantly lock the entire clamping head, exhibiting extremely high rigidity. This "rigid-flexible" characteristic fundamentally solves the contradiction between clamping force and workpiece deformation, achieving non-destructive, high-stability clamping of irregularly shaped and precision parts.

[0036] Specifically, the automatic feeding device B6 includes a feeding push rod groove device 64 fixedly connected to the machine tool base 51. A feeding cylinder 63 is fixedly installed at one end of the feeding push rod groove device 64, and a feeding groove device 62 is fixedly installed on one side of the feeding push rod groove device 64.

[0037] In this embodiment, the automatic feeding device B6 is fixedly connected to the machine tool base 51 via the support plate 642 of the feeding pusher slot device 64. The automatic feeding box 61 serves as a material bin and is connected to the feeding pusher slot device 64 via a two-stage feeding slot support frame 644. The feeding slot device 62 is independently supported by its feeding bracket 621 and support legs 622, and its feeding slot 623 is used to guide the workpiece. The feeding cylinder 63 serves as a power source, driving the pusher 631 and pusher plate 632 to push the workpiece from the automatic feeding box 61 forward within the pusher slot 641. The secondary pusher 633 is responsible for pushing the workpiece from the feeding path into the processing station. This system realizes the automatic and orderly supply of blanks and is an important component of an automated production line.

[0042] Specifically, the automatic feeding device A2 includes a base plate 20 fixedly connected to the machine tool base 51. A frame 26 is fixedly installed on the upper surface of the base plate 20. A feeding guide rail 22 is fixedly installed inside the frame 26 and on the upper surface of the base plate 20. A connecting plate 29 is fixedly installed on the upper surface of the frame 26. A lifting mounting plate 21 is fixedly installed on one side of the connecting plate 29. A limiter 25 is fixedly installed on the upper surface of the lifting mounting plate 21. A lifting threaded rod 24 for moving the connecting ring 28 up and down is fixedly installed on one side of the lifting mounting plate 21.

[0043] In this embodiment, the automatic feeding device A2 is fixed to the machine tool base 51 via the base plate 20. Its frame 26 contains a feeding guide rail 22 for precisely guiding the workpiece. The lifting drive motor 23 is fixed via the connecting plate 29, driving the lifting threaded rod 24 to rotate, thereby causing the connecting ring 28 sleeved on the threaded rod to drive the end effector (such as a robotic arm, not fully shown in the figure) to move vertically. The limit switch 25 ensures the accuracy of the lifting stroke. This device is responsible for picking up the workpiece from a production line or the feeding guide rail 22 and accurately placing it into the fixture at the cutting station, completing the final step of the feeding process and achieving full automation.

[0044] S1: Workpiece loading and initialization The workpiece to be processed is transported to the preset position by the automatic feeding device A2 or the automatic feeding device B6; the automatic picking head 745 of the cutting device 7 grabs the workpiece under the drive of the automatic picking cylinder 742, and transfers and clamps the workpiece on the fixture of the cutting station A1 or the cutting station B3. S2: Adaptive Flexible Clamping The fixtures at the clamping station perform clamping operations: When cutting station A1 is used, the internal clamping block drive cylinder 135 drives the internal clamping block 134 to clamp the workpiece from the inside, and the external clamping block 131 works together to complete the centering and fixing of the workpiece. When cutting station B3 is used, each clamping cylinder 332 drives the flexible clamping head 333 to move radially. After the flexible clamping head 333 contacts the workpiece, its head-shaped contact head 3331 undergoes adaptive deformation to conform to the workpiece contour. After the pressure increases, the internal porous sintered skeleton 3332 works together with the incompressible hydraulic oil to form a rigid support, achieving high rigidity and non-destructive clamping. S3: Multi-axis linkage cutting machining When the rotation drive motor A11 or the rotation drive motor B31 is started, it drives the clamped workpiece to rotate. At the same time, the Y-axis drive motor 72 and the X-axis moving motor 75 of the cutting device 7 work together to drive the Y-axis moving plate 73 and the X-axis moving plate 74 to move through the threaded transmission rod, respectively, and drive the cutting tool structure 744 to cut the rotating workpiece according to the preset trajectory. S4: Workpiece transfer and temporary storage are optional. When workpiece transfer is required between cutting station A1 and cutting station B3, the automatic pick-up head 745 performs a gripping action to move the workpiece that has completed one process from one station and place it in the workpiece temporary storage area 743 or directly transfer it to another station for clamping. S5: Finished Product Unloading and Collection After processing, the fixture releases the workpiece, and the automatic part-retrieving head 745 grabs the finished workpiece and releases it to the workpiece collection point 53. Under the influence of gravity or driven by the collecting motor 41, the finished workpiece is discharged from the finished product outlet 42 via the finished product collection device 4, completing the entire processing cycle.
