Description

Technical Field

[0001] This invention belongs to the technical field of machining and conveying devices, and specifically relates to an automatic feeding device. Background Technology

[0002] In modern machining, to improve production efficiency and automation, machine tools are typically equipped with automatic feeding devices to achieve continuous and efficient workpiece processing. Traditional automatic feeding methods mostly rely on industrial robots to transport and position workpieces from the feed channel or hopper to the machine tool fixture. Robots, through programming to control their multi-axis movements, can flexibly grasp workpieces and accurately place them in the machine tool's clamping components, thus finding widespread application in automated production lines.

[0003] However, as the manufacturing industry increasingly demands higher standards for cost control, space utilization, and production cycle time, the traditional solution of using robotic arms for material handling has revealed numerous shortcomings. Firstly, industrial robotic arms themselves have complex structures and high purchase costs, requiring supporting control systems, safety devices, and regular maintenance, resulting in high overall usage and maintenance costs, which is detrimental to the widespread adoption by small and medium-sized enterprises. Secondly, robotic arms require significant operating space during operation; their rotation and extension movements often occupy valuable workshop space around the machine tool, limiting the compactness of equipment layout, especially becoming a major bottleneck in space-constrained production environments. Furthermore, the time required for a robotic arm to complete a full material handling, transfer, and unloading operation is relatively long, with complex motion trajectories. Acceleration and deceleration processes affect the overall cycle time, making it difficult to further increase the material handling speed, severely restricting the processing efficiency of machine tools, especially in high-volume, high-speed processing scenarios, becoming a bottleneck in the production line.

[0004] Therefore, there is an urgent need for an automatic feeding device that is simple in structure, low in cost, occupies little space, and has a fast feeding speed, in order to overcome the shortcomings of the existing robotic arm feeding method and meet the needs of efficient, economical, and compact automated processing. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an automatic feeding device in view of the current state of the prior art.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: An automatic feeding device is proposed for automatically transporting workpieces to the clamping components of a machine tool, the automatic feeding device comprising:

[0007] A feed channel for receiving and conveying the workpiece to be processed;

[0008] A receiving block, located at the end of the movement path of the workpiece on the feeding channel, is used to receive the workpiece from the feeding channel;

[0009] A conveying component for transporting a workpiece from the receiving block to the clamping component; the conveying component includes a receiving tray and a clamping block movably disposed above the receiving block; the conveying component has a receiving state and a feeding state; wherein...

[0010] When in the receiving state, the conveying component drives the receiving tray and the clamping block to move synchronously toward the receiving block, and the clamping block rotates around its own axis during the movement, so that one end of it abuts against the side wall of the workpiece, clamping the workpiece between the receiving tray and the clamping block.

[0011] When in the feeding state, the conveying component drives the receiving tray to push the workpiece toward the clamping component, so as to send the workpiece into the clamping range of the clamping component.

[0012] In the aforementioned automatic feeding device, the feeding channel and the receiving block are integrally formed or separately arranged.

[0013] The aforementioned automatic feeding device also includes a limiting block located on one side of the conveying component;

[0014] The transport component also includes a movable base and a mounting base, wherein the movable base is fixedly connected to the mounting base;

[0015] The receiving tray is movably mounted on the movable seat, and the direction of movement is perpendicular to the direction of movement of the workpiece on the feeding channel;

[0016] The clamping block is rotatably mounted on the mounting base, with its first end for contacting the side wall of the workpiece, its second end connected to an elastic element, and the other end of the elastic element fixed to the mounting base.

[0017] The second end of the clamping block also contacts the limiting block;

[0018] When the conveying component moves the moving seat toward the receiving block, the second end of the abutting block disengages from the limiting block, the elastic element releases its elastic force, and drives the abutting block to rotate around its axis, so that the first end abuts against the side wall of the workpiece.

[0019] In the above-mentioned automatic feeding device, at least two guide columns are provided on the moving seat along the moving direction of the receiving tray, and the other ends of the at least two guide columns are connected to an end plate.

[0020] A movable block is slidably sleeved on the guide post, and the receiving tray is disposed on the movable block;

[0021] The end plate is provided with a first driving member, the output end of which is connected to the moving block and is used to drive the moving block to slide along the guide post.

[0022] In the aforementioned automatic feeding device, the limiting block is provided with an adjustable adjusting rod, one end of which is in contact with the second end of the pressing block;

[0023] When adjusting the position of the adjusting rod, the pre-deformation of the elastic element is changed.

[0024] In the aforementioned automatic feeding device, the receiving block is provided with a guide groove, and the bottom of the mounting base extends into the guide groove to provide guidance when the transported item moves.

[0025] In the aforementioned automatic feeding device, the receiving tray has a receiving groove on the side facing the receiving block for accommodating a portion of the outer periphery of the workpiece.

[0026] The aforementioned automatic feeding device further includes a first fixed base, and the conveying component further includes:

[0027] The second driving member is disposed on the first fixed base, and the movable base is movably disposed on the first fixed base and connected to the output end of the second driving member;

[0028] A fixed platform is set on the first fixed base, and the receiving block and the limiting block are both fixed on the fixed platform.

[0029] In the above-mentioned automatic feeding device, a second fixed seat is provided on one side of the feeding channel, a third driving component is installed on the second fixed seat, and a baffle rod is connected to the output end of the third driving component.

[0030] The third driving component drives the baffle rod to extend into or out of the feeding channel to block or release the movement of the workpiece toward the receiving block.

[0031] In the aforementioned automatic feeding device, the output end of the third driving component is connected to a connecting plate, and two baffle rods are spaced apart on the connecting plate.

[0032] The feeding channel is inclined relative to the moving direction of the stop bar;

[0033] When the third driving component drives the connecting plate to move the two baffle rods out of the feeding channel, the workpiece between the two baffle rods is released, while the workpiece on the baffle rod side away from the receiving block is still blocked.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] (1) By setting up a clamping conveyor consisting of a receiving tray and a clamping block, the complex multi-axis structure of traditional robotic arms is eliminated. Simple linear motion combined with adaptive clamping action is used to achieve workpiece gripping and pushing. In the receiving state, the clamping block automatically rotates and presses against the side wall of the workpiece during the movement to form a stable clamp; in the conveying state, the workpiece is directly pushed into the clamping area. The action is smooth and the response is rapid. This structure significantly reduces equipment cost and maintenance difficulty, saves space, and improves the loading cycle time. It is suitable for large-volume, high-paced automated processing scenarios.

[0036] (2) By setting a limit block and an elastic linkage mechanism, the clamping action of the abutment block is automatically triggered. When the conveying part moves forward, the tail end of the abutment block disengages from the constraint of the limit block and automatically rotates under the action of the elastic element to complete the clamping action. No additional cylinder or motor control is required, and the structure is simple, the response is fast, and the action is reliable. This design uses the principle of mechanical interference and elastic reset to achieve "move and clamp", which greatly simplifies the control system, improves the synchronization and stability of the action, and effectively prevents the workpiece from shifting or falling off during the pushing process.

[0037] (3) The guiding system composed of double guide columns and end plates provides high-precision, low-friction linear motion support for the receiving tray, significantly improving motion stability and repeatability accuracy; the first driving component directly drives the moving block through the end plate, with uniform force, effectively preventing jamming caused by off-center loading.

[0043] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0044] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0045] like Figures 1 to 4 As shown, the present invention provides an automatic feeding device for automatically transporting workpieces to a clamping component on a machine tool. The machine tool can be a lathe, a three-axis or five-axis machining center, and the clamping component is a structure such as a three-jaw chuck fixed to the machine tool spindle. The automatic feeding device includes: a feeding channel 1, a receiving block 2, and a conveying component 3.

[0046] Specifically, feed channel 1 is used to receive and transport workpieces to be processed. Workpieces can be placed on feed channel 1 manually or fed onto feed channel 1 by equipment such as conveyor belt feeders.

[0047] In one embodiment, the feeding channel 1 is an inclined slide. After the workpiece enters the feeding channel 1, it moves from the inlet to the outlet of the feeding channel 1 under its own gravity.

[0048] Of course, in another embodiment, the feed channel 1 can also be a power conveying component similar to a conveyor belt.

[0049] The receiving block 2 serves as the workpiece gripping position in the automatic feeding device. It is located at the end of the workpiece's movement path on the feeding channel 1 and is used to receive the workpiece on the feeding channel 1. The receiving block 2 is provided with a concave positioning groove that matches the shape of the workpiece. When the workpiece moves from the outlet of the feeding channel 1 to the receiving block 2, it is buffered and positioned.

[0050] The concave positioning groove on receiving block 2 not only positions the workpiece but also assists in guiding it to receiving tray 4. Specifically, the workpiece slides down from feed channel 1 into the concave positioning groove of receiving block 2 under its own weight. During the design process, the inclination angle of feed channel 1 needs to be set appropriately to ensure that the workpiece will not be thrown out of the groove due to inertia after entering it. After entering the concave positioning groove, the workpiece will not stop immediately due to inertia but will instead remain against the left side wall of the concave positioning groove (refer to...). Figure 1 After the collision, it bounces back to the right and enters the receiving tray 4, where it is successfully received by the receiving tray 4.

[0051] The conveying unit 3 is responsible for transporting the workpiece from the receiving block 2 to the clamping component of the machine tool, serving as a workpiece conveying unit. The conveying unit 3 includes a receiving tray 4 and a clamping block 5 movably disposed above the receiving block 2, and has a receiving state and a conveying state.

[0052] When in the receiving state, the conveying component 3 drives the receiving plate 4 and the clamping block 5 to move synchronously toward the receiving block 2, and the clamping block 5 rotates around its own axis during the movement, so that one end of it presses against the side wall of the workpiece, clamping the workpiece between the receiving plate 4 and the clamping block 5.

[0053] When in transport mode, the transport component 3 drives the receiving tray 4 to push the workpiece toward the clamping component so as to send the workpiece into the clamping range of the clamping component.

[0054] Reference Figure 1 When the workpiece enters the receiving block 2 from the outlet of the feeding channel 1, the conveying component 3 drives the receiving plate 4 and the clamping block 5 to move downward synchronously.

[0055] When the receiving tray 4 moves to the point where its center line is basically aligned with the center line of the workpiece, the workpiece enters the receiving tray 4 under the buffering and positioning effect of the receiving block 2. At the same time, one end of the clamping block 5 is pressed against the outer wall of the workpiece, clamping the workpiece between the receiving tray 4 and the clamping block 5, thus achieving reliable fixation.

[0056] During the workpiece fixing process, the conveyor 3 continuously drives the receiving tray 4 and the clamping block 5 to move synchronously, transporting the workpiece to the clamping components of the machine tool. Then, the receiving tray 4 moves along... Figure 1 The workpiece is pushed into the clamping range of the machine tool clamping components in the indicated direction (from the lower right to the upper left), completing the workpiece transport operation. Subsequently, the receiving tray 4 moves in the reverse direction to reset, and the transport component 3 drives the clamping block 5 and the receiving tray 4 to move upward to reset, preparing for the next workpiece transport.

[0057] This solution eliminates the complex multi-axis structure of traditional robotic arms by setting up a clamping conveyor 3 consisting of a receiving tray 4 and a clamping block 5. It uses simple linear motion combined with adaptive clamping action to achieve workpiece gripping and pushing.

[0058] When receiving material, the clamping block 5 automatically rotates and presses against the side wall of the workpiece during movement, forming a stable clamp.

[0059] In transport mode, the workpiece is directly pushed into the clamping area with smooth and rapid action. This structure significantly reduces equipment costs and maintenance difficulty, saves space, and improves loading cycle time, making it suitable for high-volume, high-paced automated processing scenarios.

[0060] It is worth mentioning that when the receiving tray 4 pushes the workpiece into the clamping range of the clamping component, it can rotate around its own axis, so that the clamping component clamps the workpiece while rotating, and the workpiece and the receiving tray 4 rotate synchronously. Thus, without damaging the outer surface of the workpiece, the machine tool can clamp the workpiece without stopping the clamping component, which further improves the workpiece transportation efficiency.

[0061] In this design, the feeding channel 1 and the receiving block 2 are either integrally formed or separately configured.

[0062] The feeding channel 1 and the receiving block 2 are integrally formed or detachably connected, which allows for flexible selection of manufacturing processes (such as casting, welding or modular assembly) according to actual installation needs, improving structural strength and positioning accuracy, and facilitating later maintenance and replacement.

[0063] The split design allows for individual replacement when parts are damaged, reducing maintenance costs; while the one-piece molding improves overall rigidity and stability, reduces the impact of vibration on feeding accuracy, and enhances the adaptability and reliability of the device.

[0064] This solution also includes a limiting block 6 located on one side of the conveying component 3. The conveying component 3 also includes a movable seat 7 and a mounting seat 8, wherein the movable seat 7 is fixedly connected to the mounting seat 8. The receiving tray 4 is movably disposed on the movable seat 7, and the sliding direction is perpendicular to the movement direction of the workpiece on the feeding channel 1; the abutting block 5 is rotatably disposed on the mounting seat 8, the first end of which is used to contact the side wall of the workpiece, and the second end is connected to an elastic element 9, the other end of which is fixed to the mounting seat 8; the second end of the abutting block 5 also contacts the limiting block 6. When the conveying component 3 drives the movable seat 7 to move toward the receiving block 2, the second end of the abutting block 5 disengages from the limiting block 6, the elastic element 9 releases its elastic force, driving the abutting block 5 to rotate around its axis, so that the first end abuts against the side wall of the workpiece.

[0065] In one embodiment, the elastic element 9 is preferably a spring with hooks at both ends, and the second end of the clamping block 5 and the mounting base 8 are provided with mounting holes that match the hooks.

[0066] In the initial state (refer to) Figure 1 The elastic element 9 is in a stretched state and abuts against the second end of the block 5. Figure 1 The left end of the middle clamping block 5 is in contact with the limiting block 6 and is clamped.

[0067] When the conveying component 3 moves the receiving tray 4 and the clamping block 5 downwards synchronously, the second end of the clamping block 5 disengages from the limiting block 6, and the elastic component 9 begins to contract, thus driving the first end of the clamping block 5 downwards. Figure 1 The right side of the middle clamping block 5 rotates downward, thereby pressing against the outer wall of the workpiece, and finally fixing the workpiece between the clamping block 5 and the receiving tray 4.

[0068] When the conveying component 3 drives the receiving tray 4 and the clamping block 5 to move in the opposite direction, the second end of the clamping block 5 re-contacts the limiting block 6, causing the clamping block 5 to rotate to the initial state and stretch the elastic component 9, so that it enters the energy storage state again, preparing for the next conveying of the workpiece.

[0069] This solution achieves automatic triggering of the clamping action of the abutment block 5 by setting a limit block 6 and an elastic linkage mechanism.

[0070] When the transport piece 3 moves forward, the tail end of the clamping block 5 is released from the constraint of the limiting block 6 and automatically rotates under the action of the elastic element 9 to complete the clamping action. No additional cylinder or motor control is required. The structure is simple, the response is fast, and the action is reliable.

[0071] This design utilizes the principles of mechanical interference and elastic reset to achieve "clamping upon movement," which greatly simplifies the control system, improves the synchronization and stability of actions, and effectively prevents the workpiece from shifting or falling off during the pushing process.

[0072] When the transport component 3 is in the transport state, in order to realize the movement of the receiving tray 4 towards the machine tool clamping component, in this solution, the moving base 7 is provided with at least two guide posts 10 along the moving direction of the receiving tray 4, and the far ends of the two guide posts 10 are connected to an end plate 11. A moving block 12 is slidably sleeved on the guide post 10, and the receiving tray 4 is disposed on the moving block 12. The end plate 11 is provided with a first driving component 13, the output end of which is connected to the moving block 12, for driving the moving block 12 to slide along the guide post 10, thereby driving the receiving tray 4 to reciprocate relative to the clamping component.

[0073] The first driving component 13 is preferably a cylinder, which has a rapid response and can realize the rapid movement of the receiving tray 4. The moving block 12 is sleeved on the guide post 10 to ensure the guiding accuracy during its movement. By pushing the moving block 12 with the first driving component 13, the receiving tray 4 can be smoothly pushed and reset.

[0074] In another embodiment, the moving block 12 and the receiving tray 4 are connected by a bearing: the moving block 12 is provided with a bearing, and the receiving tray 4 is provided with an extension shaft, which is fixed to the inner ring of the bearing. This structure allows the receiving tray 4 to rotate around the shaft during the pushing process, which facilitates cooperation with the rotating clamping components to complete the feeding and avoids damage to the workpiece surface.

[0075] This structure employs a guiding system consisting of dual guide columns 10 and end plates 11, which provides high-precision, low-friction linear motion support for the receiving tray 4, significantly improving motion stability and repeatability.

[0076] The first driving component 13 directly drives the moving block 12 through the end plate 11, resulting in uniform force distribution and effectively preventing jamming caused by uneven load.

[0077] The overall design enhances the system's dynamic response capability, extends its service life, simplifies the assembly and debugging process, and improves the operational stability and reliability of the device.

[0078] Furthermore, the limiting block 6 is provided with an adjustable adjusting rod 14, one end of which is in contact with the second end of the pressing block 5. By adjusting the position of the adjusting rod 14, the pre-deformation amount (i.e., pre-tightening amount) of the elastic element 9 can be changed.

[0079] The adjustable connection between the adjusting rod 14 and the limiting block 6 can be achieved through a threaded connection.

[0080] For example, an external thread is provided on the outer wall of the adjusting rod 14, and a matching internal thread hole is provided on the limiting block 6, and the two are threadedly connected.

[0081] Of course, in another embodiment, a bolt can also be used directly as the adjusting rod 14.

[0082] By setting an adjustable adjustment rod 14, the initial tension (pre-deformation) of the elastic element 9 can be precisely adjusted, thereby controlling the clamping force of the clamping block 5 on the workpiece.

[0083] This design allows the device to adapt to workpieces of different materials, sizes, or surface properties, preventing damage due to excessive clamping force or loosening and detachment due to insufficient clamping force. The adjustment process is simple to operate, requiring no replacement of parts, significantly improving the equipment's versatility and production flexibility.

[0084] In this design, the receiving block 2 is provided with a guide groove 15, and the bottom of the mounting base 8 extends into the guide groove 15 to provide guidance when the transport component 3 moves.

[0085] The bottom of the mounting base 8 is embedded in the guide groove 15 on the receiving block 2, forming a stable guiding relationship, which plays a role in precise guidance and preventing deviation during the overall forward and backward movement of the transport component 3.

[0086] This structure effectively suppresses shaking and tilting during movement, ensuring accurate alignment of the receiving tray 4 and the clamping block 5 relative to the workpiece, improving the repeatability and stability of the feeding action, and enhancing the rigidity and anti-interference capability of the entire conveying mechanism.

[0087] In order to enable the receiving tray 4 and the clamping block 5 to stably receive and clamp the workpiece, the receiving tray 4 is provided with a receiving groove 16 on the side facing the receiving block 2 to receive part of the outer peripheral surface of the workpiece.

[0088] After the receiving groove 16 is set, the receiving tray 4 can partially cover the outer periphery of the workpiece during the clamping process, increasing the contact area and improving the clamping stability. It is especially suitable for cylindrical or irregularly shaped workpieces, effectively preventing the workpiece from rolling or sliding laterally during the pushing process.

[0089] Meanwhile, the receiving slot 16 also has a preliminary positioning function, which helps the workpiece to be automatically centered, reduces clamping deviation, and improves the success rate of loading and processing consistency.

[0090] This solution also includes a first fixed base 17, and the conveying component 3 also includes a second driving component 18, which is disposed on the first fixed base 17; the movable base 7 is movably disposed on the first fixed base 17 and connected to the output end of the second driving component 18; it also includes a fixed platform 19, which is disposed on the first fixed base 17, and the receiving block 2 and the limiting block 6 are both fixed on the fixed platform 19.

[0091] The first fixed base 17 serves as the support and mounting base for the entire automatic feeding device, and is used to fix the device on the machine tool.

[0092] Preferably, the first fixed seat 17 has a plate-like structure. The second driving component 18 can be a cylinder, a linear motor, or a motor-screw structure (such as a servo motor with a ball screw) to drive the moving seat 7 to reciprocate in a predetermined direction, thereby driving the receiving tray 4 and the clamping block 5 to move synchronously.

[0093] The fixed platform 19 serves as the mounting base for the receiving block 2 and the limiting block 6, and is preferably fixed to the first fixed seat 17 by means of a threaded connection.

[0094] This solution integrates the drive components, motion components, and functional components onto a unified rigid base by setting up independent first fixed base 17 and fixed platform 19, forming a modular structure.

[0095] This design not only improves the overall structural rigidity and seismic performance, but also facilitates transportation, installation, and subsequent maintenance. The centralized arrangement of key components reduces external pipeline connections, optimizes spatial layout, and ensures coordination and synchronization between moving parts, significantly enhancing the reliability and safety of the system.

[0096] A second fixed seat 20 is provided on one side of the feeding channel 1. A third driving member 21 is installed on the second fixed seat 20, and a baffle rod 22 is connected to its output end. The third driving member 21 drives the baffle rod 22 to extend into or out of the feeding channel 1 to block or release the movement of the workpiece toward the receiving block 2.

[0097] The third driving component 21 is preferably a cylinder. The second fixed base 20 serves as a support component for the third driving component 21.

[0098] In one embodiment, the feed channel 1 is fixed to the second fixed seat 20 by a threaded connection. The third driving member 21 drives the baffle rod 22 to move closer to or further away from the feed channel 1, thereby blocking and releasing the workpiece on the feed channel 1, thus ensuring that only one workpiece enters the receiving block 2 at a time.

[0099] By setting a baffle bar 22 controlled by the third drive component 21, the orderly control of the workpiece flow is achieved, avoiding the accumulation or collision of multiple workpieces continuously entering the receiving area.

[0100] The stop bar 22 only retracts after the current workpiece is clamped and pushed to the clamping component, allowing the next workpiece to enter the receiving position. This design enables precise feeding of individual workpieces, ensures controllable feeding rhythm and clear sequence, effectively prevents misoperation and equipment failure, and improves the safety and stability of system operation.

[0101] More specifically, the output end of the third driving component 21 is connected to a connecting plate 23, and two baffle rods 22 are spaced apart on the connecting plate 23; the feeding channel 1 is inclined relative to the moving direction of the baffle rods 22; when the third driving component 21 drives the connecting plate 23 to move the two baffle rods 22 out of the feeding channel 1, the workpiece between the two baffle rods 22 is released, while the workpiece on the side of the baffle rod 22 that is away from the receiving block 2 is still blocked.

[0102] The design employs a double-stop bar 22 in conjunction with an inclined feed channel 1, achieving a "sequential release, staggered blocking" feeding logic. When the two stop bars 22 retract simultaneously, only the single workpiece between them is released, while the remaining workpieces are still blocked by the rear stop bar 22, eliminating the risk of multiple workpieces sliding down at the same time. The inclined feed channel 1 helps workpieces automatically converge under gravity, ensuring consistent positioning. This structure further improves the accuracy and reliability of feeding, making it particularly suitable for continuous feeding of densely packed workpieces, significantly improving the overall automation level and operating efficiency of the machine.

[0103] In summary, this solution provides an automated feeding device that is compact, reliable, low-cost, and highly efficient. This device eliminates the complex traditional method of relying on robotic arms for workpiece handling, achieving automatic workpiece receiving and precise delivery through the coordinated operation of the innovatively designed feeding channel 1, receiving block 2, and clamping conveyor 3.

[0104] Among them, the conveying component 3 adopts a combination structure of receiving tray 4 and rotatable clamping block 5, combined with elastic drive and limit trigger mechanism, to automatically complete the clamping action of workpiece during movement, without the need for additional control components, simplifying the system structure and improving the response speed.

[0105] Meanwhile, the multiple guiding and positioning structures, such as the guide groove 15 and guide post 10, ensure the smoothness and repeatability of the movement process; and the design of the adjustable adjustment rod 14 enhances the adaptability to different workpieces. In addition, the cooperation between the double stop rod 22 and the inclined feed channel 1 enables the orderly release of workpieces one by one, effectively avoiding feeding chaos.

[0106] Overall, this solution has significant advantages such as simple structure, convenient maintenance, small footprint, and fast loading cycle. It not only greatly reduces the manufacturing and maintenance costs of the equipment, but also significantly improves the automation level and processing efficiency of the machine tool. It is particularly suitable for processing scenarios with large-volume and continuous production, and has good practical value and broad prospects for promotion and application.
