Description

Technical Field

[0002] Metal cutting is a material removal and forming method in the metal forming process. It still accounts for a large proportion in today's mechanical manufacturing. The metal cutting process is a process of interaction between the workpiece and the tool. The tool removes excess metal from the workpiece to be processed and, under the premise of controlling productivity and cost, makes the workpiece obtain geometric accuracy, dimensional accuracy and surface quality that meet the design and process requirements. To achieve this process, there must be relative motion between the workpiece and the tool, that is, cutting motion, which is provided by metal cutting machine tools. The machine tool, fixture, tool and workpiece constitute a mechanical processing process system.

Debris will be generated during processing and needs to be collected to prevent a large amount of debris from accumulating on the machine tool and affecting subsequent product processing. The general collection method is mainly to use a manually operated vacuum cleaner to extract, but the lathe needs to be stopped for cleaning.

[0049] Compared with the prior art, the present invention has the following beneficial effects:

[0050] 1. The multi-axis manipulator of the present invention drives the chip removal assembly to move above the cutting area and ensures that the suction hood can accurately cover the cutting area. The horizontal drive mechanism drives the sliding seat to move according to the size and shape of the cutting area, adjusts the position of the suction branch pipe and the suction hood, and ensures that they can cover the cutting area to the maximum extent and effectively absorb the chips. The external suction device is started, and a strong suction force is generated through the suction branch pipe and the suction hood to quickly suck and discharge the chips generated during the cutting process out of the device. As the cutting process proceeds, the multi-axis manipulator and the horizontal drive mechanism work together to continuously adjust the position of the suction hood to ensure that the chips can be continuously and effectively removed. Two independent chip suction channels can work at the same time and can be flexibly adjusted according to the size and shape of the cutting area. This design not only improves the efficiency of chip removal, but also avoids processing interruptions caused by mutual interference between the chip suction channels. By accurately controlling the spacing between the two chip suction channels, the device can ensure that no physical interference is caused to the workpiece during the processing. This means that the processing process can continue without stopping for chip management, thereby significantly improving production efficiency. In this way, the present invention achieves fast and accurate chip removal through an optimized chip suction component and a horizontal drive mechanism. The design of a multi-axis manipulator and a sliding seat enables the device to adapt to workpieces of different shapes and sizes. Two independent chip suction channels ensure that the processing process does not need to be stopped due to chip management, thereby achieving efficient, flexible and non-interference chip management.

[0051] 2. The chip suction assembly of the present invention also includes a main air suction pipe, a bypass air suction pipe, and two telescopic hoses; the main air suction pipe serves as the center of the entire chip suction system, and its air outlet end is connected to the air suction end of the external suction device, and is responsible for sucking the chips out of the device. The air inlet end of the main air suction pipe is connected to the air outlet ends of the two telescopic hoses through the bypass air suction pipe. The design of the bypass air suction pipe ensures that the main air suction pipe can receive the chips from the two air suction branch pipes at the same time, thereby improving the chip suction efficiency. The two telescopic hoses are respectively connected between the air outlet ends of the two air suction branch pipes and the bypass air suction pipe. The design of the telescopic hose not only increases the flexibility of the chip suction system, but also can automatically adjust the length according to the movement of the sliding seat, thereby ensuring that the chip suction channel is unobstructed.

[0052] 3. The present invention enables the exhaust branch pipe to rotate to a preset angle through the design of the rotary drive assembly, which greatly enhances the flexibility of the device and enables it to more easily adapt to cutting areas of different angles and positions. Through the dual adjustment of sliding and rotating, the device can cover the cutting area more accurately, improve the chip capture efficiency, and reduce chip splashing and residue. The design of the rotating seat and the rotary drive mechanism ensures the stability of the exhaust branch pipe during the rotation process, avoiding the decrease in chip suction efficiency due to vibration or deviation.

[0053] 4. The present invention is driven by a horizontal drive mechanism, and the two sliding seats can move in a direction of approaching or moving away from each other. When the two sliding seats approach each other, the two arc-shaped shielding parts also approach and finally enclose to form a circular closed structure; when the two sliding seats move away from each other, the two arc-shaped shielding parts open to facilitate cutting operations or cleaning chips. When the two arc-shaped shielding parts are in an enclosed state, they can form a complete shielding barrier, effectively preventing chips from splashing or scattering outside the cutting area. This not only improves the efficiency of chip management, but also ensures the safety of operators. In this way, the present invention improves the chip capture efficiency and management efficiency through the coordinated work of the shielding component and the chip removal component, ensuring the smooth progress of the cutting process. The flexible movement of the shielding component driven by the horizontal drive mechanism realizes flexible shielding and opening operations of the cutting area, meeting the needs of different cutting scenarios. The effective shielding of the shielding component prevents the splashing and scattering of chips, ensuring the safety of operators.

[0054] 5. The present invention enables the chip removal component to be flexibly adjusted in the horizontal direction and the rotational direction through the design of the mobile component, thereby adapting to the requirements of different cutting scenarios and machine tool layouts.

[0055] 6. The present invention realizes the precise positioning of the chip removal component in three-dimensional space through a three-level adjustment mechanism, meeting the requirements of different cutting scenarios and machine tool layouts. Each level of the adjustment mechanism is driven by a reduction motor, which realizes precise control of the angle and improves the chip removal efficiency. The components are tightly connected, the structure is compact, and the space occupied is small, which is convenient for installation and use on the machine tool. BRIEF DESCRIPTION OF THE DRAWINGS

[0076] Specifically, the two sliding seats 22 are slidably installed in the installation cavity 211 respectively;

[0077] Specifically, the debris suction assembly 23 includes two suction branches 231 and a plurality of suction hoods 232;

[0078] Two air extraction branches 231 are respectively installed on two sliding seats 22; the air outlet ends of the two air extraction branches 231 are respectively used to connect with the air extraction ends of external suction equipment to form two independent debris suction channels; the two air extraction branches 231 are respectively provided with a plurality of air extraction ports, and a suction hood 232 is respectively installed at the air extraction port on each air extraction branch 231;

[0079] The horizontal driving mechanism 24 is used to drive the two sliding seats 22 to move toward or away from each other, so as to drive the two air extraction branches 231 to move toward or away from each other.

[0080] On the basis of the above structure, the multi-axis manipulator drives the chip removal assembly to move above the cutting area and ensures that the suction hood 232 can accurately cover the cutting area. The horizontal drive mechanism 24 drives the sliding seat 22 to move according to the size and shape of the cutting area, adjusts the position of the suction branch pipe 231 and the suction hood 232, and ensures that they can cover the cutting area to the maximum extent and effectively absorb the chips. The external suction device is started, and a strong suction force is generated through the suction branch pipe 231 and the suction hood 232 to quickly suck and discharge the chips generated during the cutting process out of the device. As the cutting process proceeds, the multi-axis manipulator and the horizontal drive mechanism 24 work together to continuously adjust the position of the suction hood 232 to ensure that the chips can be continuously and effectively removed. The two independent chip suction channels can work at the same time and can be flexibly adjusted according to the size and shape of the cutting area. This design not only improves the efficiency of chip removal, but also avoids processing interruptions caused by mutual interference between the chip suction channels. By accurately controlling the spacing between the two chip suction channels, the device can ensure that no physical interference is caused to the workpiece during the processing process. This means that the machining process can continue without stopping for chip management, thereby significantly improving production efficiency. In this way, the present invention achieves fast and accurate chip removal through the optimized chip suction assembly 23 and the horizontal drive mechanism 24, and the design of the multi-axis manipulator and the sliding seat 22 enables the device to adapt to workpieces of different shapes and sizes. The two independent chip suction channels ensure that the machining process does not need to be stopped for chip management, thereby achieving efficient, flexible and non-interference chip management.

The air inlet end of the main air extraction pipe 233 is connected to the air outlet ends of the two telescopic hoses 235 through the diverter air extraction pipe 234. The design of the diverter air extraction pipe 234 ensures that the main air extraction pipe 233 can simultaneously receive the chips from the two air extraction branches 231, thereby improving the chip suction efficiency. The two telescopic hoses 235 are respectively connected between the air outlet ends of the two air extraction branches 231 and the diverter air extraction pipe 234. The design of the telescopic hose 235 not only increases the flexibility of the chip suction system, but also can automatically adjust the length according to the movement of the sliding seat 22, thereby ensuring that the chip suction channel is unobstructed.

[0083] In a preferred embodiment of the present invention, the chip suction assembly 23 also includes two rotation drive assemblies, and the rotation drive assembly includes a rotating seat 236 and a rotation drive mechanism 237; the rotating seat 236 is rotatably mounted on the sliding seat 22, and the two exhaust branch pipes 231 are respectively mounted on the two rotating seats 236; the rotation drive mechanism 237 is mounted on the sliding seat 22, and the two rotation drive mechanisms 237 are used to respectively drive the two rotating seats 236 to rotate, so that the two rotating seats 236 can respectively drive the two exhaust branch pipes 231 to rotate a preset angle.

[0084] On the basis of the above structure, the design of the rotary drive assembly enables the air extraction branch pipe 231 to rotate at a preset angle, greatly enhancing the flexibility of the device and enabling it to more easily adapt to cutting areas of different angles and positions. Through the dual adjustment of sliding and rotating, the device can cover the cutting area more accurately, improve the chip capture efficiency, and reduce chip splashing and residue. The design of the rotating seat 236 and the rotary drive mechanism 237 ensures the stability of the air extraction branch pipe 231 during the rotation process, avoiding the decrease in chip suction efficiency due to vibration or deviation.

The design of the rotating seat 236 and the rotary drive mechanism 237 ensures the stability of the exhaust branch pipe 231 during the rotation process, avoiding the decrease in chip suction efficiency due to vibration or offset. The structural optimization and stable installation of the connecting plate 2371 ensure the stability of the rotary drive mechanism 237 during the rotation process, avoiding failure or damage caused by vibration or external force. The design of the extension provides a stable support platform for the rotary motor 2372, improving the installation stability and reliability of the rotary motor 2372. The design of the extension enables the rotary motor 2372 to be installed at a higher position, avoiding interference with the sliding seat 22 and other components, and improving the space utilization of the entire device.

[0095] On the basis of the above structure, the two sliding seats 22 can move in the direction of approaching or moving away from each other through the drive of the horizontal drive mechanism 24. When the two sliding seats 22 approach each other, the two arc-shaped shielding parts 252 also approach and finally enclose to form a circular closed structure; when the two sliding seats 22 move away from each other, the two arc-shaped shielding parts 252 open to facilitate cutting operations or cleaning chips. When the two arc-shaped shielding parts 252 are in an enclosed state, they can form a complete shielding barrier to effectively prevent chips from splashing or scattering outside the cutting area. This not only improves the efficiency of chip management, but also ensures the safety of operators. In this way, the present invention improves the chip capture efficiency and management efficiency through the coordinated work of the shielding component and the chip removal component, ensuring the smooth progress of the cutting process. The flexible movement of the shielding component driven by the horizontal drive mechanism 24 realizes flexible shielding and opening operations of the cutting area, meeting the needs of different cutting scenarios. The effective shielding of the shielding component prevents the splashing and scattering of chips, ensuring the safety of operators.

[0097] On the basis of the above structure, when the horizontal drive motor 241 is started, its output shaft drives the bidirectional screw 242 to rotate. Since the bidirectional screw 242 has a first threaded portion and a second threaded portion with opposite rotation directions, the two sliding seats 22 threadedly connected thereto will move in opposite directions. By controlling the forward and reverse rotation and the rotation speed of the motor, the moving direction and speed of the sliding seat 22 can be accurately controlled, thereby driving the two exhaust branches 231 to move in the direction of approaching or moving away from each other, and at the same time, the enclosure and opening operation of the shielding component can be realized. When it is necessary to shield the cutting area, the motor drives the bidirectional screw 242 to rotate so that the two sliding seats 22 approach each other, and the shielding component is enclosed to form a circular closed structure; when it is necessary to clean the chips or perform other operations, the motor drives the bidirectional screw 242 to rotate in the opposite direction so that the two sliding seats 22 move away from each other, and the shielding component opens. The design of the bidirectional screw 242 and the sliding seat 22 being built into the mounting cavity 211 makes the device structure more compact, improves the space utilization and overall aesthetics. The built-in design effectively protects the bidirectional screw rod 242 and the sliding seat 22 from interference and damage from the external environment, thereby extending the service life of the components.
