[0003] However, in the existing technology, the replacement of cutting tools mainly relies on manual operation. The operator needs to stop the machine and enter the work area to disassemble and install each tool one by one.

[0014] A method for automatically replacing parts for cutting a shower head connection cover comprises the following steps: S1. During use, when the connection cover on the turntable is processed (for example, after drilling is completed in the drilling section), the drill needs to be replaced, or when the tap needs to be replaced in the tapping section, the control system will instruct the automatic replacement device to start. Initially, the push block is controlled by the cylinder to move inside the accommodating chamber, thereby pushing the cutting tool forward inside the accommodating chamber. An electric control valve is provided at the front bottom of the accommodating chamber. When the valve is opened, the cutting tool falls vertically into the accommodating cylinder. S2. Then, when the new tool or the old tool falls into the accommodating tube, the electric push rod 1 is started to control the guide ring 1 to move downward along the guide column, driving the connecting rod 1 to rotate, thereby pulling the connecting bar downward along the accommodating tube, driving the remaining connecting bars and the driving block to move downward synchronously. Since the driving block and the driving slot are movable, the clamping blocks are pushed closer to each other until the tool is clamped and kept in a vertical state. S3. Then, servo motor 1 is started to drive the drive rod to rotate on the base. Since the drive rod is threadedly connected to the control bar and the base limits the movement direction of the control bar, the control bar slides on the base, and the length direction of the base is consistent with the radial direction of the turntable, so that the control bar moves along the radial direction of the turntable. Since one end of the guide rod is movably engaged with the end of the control bar and the other end of the guide rod is fixedly connected to the slider, when the control bar moves closer to the turntable, under the action of the guide rod, the slider moves along the slide rail closer to the turntable, so that the empty accommodating cylinder moves to the bottom of the mounting head; S4. Subsequently, servo motor 2 is started to drive sprocket 2 to rotate inside the receiving box, causing the chain belt to rotate, controlling the two sprockets 1 to rotate synchronously, thereby causing the two support plates on the top of the receiving box to rotate synchronously, rotating the receiving cylinder containing the old tool 180 degrees, and rotating the receiving cylinder containing the new tool to below the drilling device or tapping device. The drilling device or tapping device is then used to clamp the new tool and control the new tool to move upward, thereby facilitating the separation of the new tool from the receiving cylinder, allowing the receiving cylinder to return to its original position. S5. Finally, the accommodating cylinder is driven to move back through the control component. When the accommodating cylinder is reset away from the turntable, the electric push rod 2 is started to control the guide ring 2 to move downward along the guide column, causing the connecting rod 2 to rotate. At the same time, the bottom cover is pulled close to the guide column, and the guide block on the side of the bottom cover slides along the guide bar until the bottom cover releases the obstruction to the bottom of the accommodating cylinder. At the same time, the clamping block releases the clamping of the old tool, and the old tool falls downward. The receiving box is installed on the workbench to collect the old tools.

[0015] Compared with the prior art, the automatic replacement device for cutting parts of a shower head connection cover has the following beneficial effects: 1. Through an automated control system and a precision mechanical structure, the present invention's automatic replacement device for cutting parts in a shower head connection cover realizes a fully automatic replacement process for cutting tools, significantly improving production efficiency and continuous operation capabilities. The device coordinates the collaborative work of the loading component, switching component, clamping component, and opening and closing component through the control component, and can accurately complete automatic loading, stable clamping, rapid switching, and orderly recovery of cutting tools. This not only reduces operational difficulty and the risk of human error, but also significantly reduces production interruption time caused by manual tool replacement.

[0016] 2. The present invention ensures that the tool axis can perfectly coincide with the axis of the accommodating cylinder each time the tool is replaced through the precise coordination of the clamping block, connecting strip and driving block in the clamping assembly, thereby improving the installation accuracy and processing quality; at the same time, the specially designed buffer rubber strip on the edge of the bottom cover can effectively absorb the impact force when the tool falls, greatly extending the service life of the tool; in addition, all actuators are equipped with an overload protection system, which cooperates with high-precision position sensors and photoelectric switches to monitor the tool status in real time, and can promptly detect and prevent abnormal situations such as tool jamming or accidental collision, effectively avoiding mechanical damage and ensuring the long-term stable operation of the equipment.

[0017] 3. The present invention adopts a symmetrically arranged receiving tube and clamping assembly to accommodate and manage various types of cutting tools in a limited space, thereby achieving the optimal allocation of space resources; the automated tool replacement process not only avoids downtime caused by manual operation, but also realizes on-demand replacement through the intelligent tool management system, reducing tool waste; at the same time, the device can flexibly adjust the tool type and replacement frequency according to different processing requirements, thereby enhancing adaptability and practicality.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] In the prior art, such as Figure 1 and Figure 2 As shown, the turntable 12 is installed on the workbench, and four groups of clamps 13 are installed on the turntable 12, and the number of each group of clamps 13 is two; the outer side of the turntable 12 is divided into four sections clockwise, and each section independently completes an operation. Section one is the loading section, and the unprocessed raw materials of the two shower heads are respectively installed on a group of clamps 13; Section two is the drilling section, and a drilling device 14 is provided in Section two. Each drilling device 14 is equipped with two drill bits, and a drill bit is installed at the bottom of the drill bit. The raw material is drilled by the drill bit to form a hole. Rough material; Interval three is the tapping interval, and Interval three is provided with a tapping device 15, each tapping device 15 is equipped with two tapping heads, and a tap is installed at the bottom of the tapping head, and the inner surface of the rough material is processed into an internal thread by the tap to form a fine material; Interval four is the unloading interval, and the fine material is removed from the fixture 13; the turntable 12 is controlled to rotate by the motor on the workbench, so as to switch the workpiece on each set of fixtures 13 from the previous interval to the next interval; the devices of Intervals three and four are shown in the figure, but it should be foreseeable that they belong to the existing technical solutions.

[0022] like Figure 1-9As shown, the present invention provides a technical solution: an automatic replacement device for cutting parts of a shower head connecting cover, comprising a control component 1, a group of symmetrical loading components 2 being fixedly connected to the control component 1, a group of symmetrical switching components 3 being fixedly connected to the control component 1, the switching component 3 comprising a guide column 301, the guide columns 301 being symmetrically arranged, the outer sides of the guide columns 301 being fixedly connected with a support plate 302, the top of the support plate 302 being fixedly connected with a group of symmetrical accommodating cylinders 303, the top of the support plate 302 being provided with a clamping component 4 for clamping the cutting tool, the bottom of the support plate 302 being provided with a group of symmetrical bottom covers 16, the bottom covers 16 being respectively attached to the bottom of the accommodating cylinder 303, the bottom of the support plate 302 being provided with an opening and closing component 5, and the opening and closing component 5 being connected to the bottom cover 16.

[0023] When the cutting tools (specifically taps and drills in this embodiment) are worn, they are usually replaced manually. However, the present application automatically replaces them in the following manner: the loading component 2 can add the cutting tools to the interior of the accommodating cylinder 303, and then, through the control component 1, simultaneously drive the tool in interval two to move below the drilling device 14, and drive the tool in interval three to move below the tapping device 15. The old drill under the drilling device 14 is removed and replaced, and the old tap under the tapping device 15 is removed and replaced; finally, the replaced old tools are collected together.

[0024] During the operation of this device, all actuators such as electric push rods and servo motors are equipped with overload protection mechanisms to prevent mechanical damage caused by tool jamming or accidental collision; at the same time, position sensors and photoelectric switches are added to the linkage control of the control component 1 and the loading component 2 and the switching component 3 to monitor the delivery, clamping and replacement status of the tool in real time. Once an abnormality is detected (such as the tool does not fall correctly into the accommodating cylinder 303 or the clamping fails), the system will automatically trigger an alarm and suspend operation to avoid damage to the equipment or workpiece due to misoperation; in addition, in the matching structure of the support plate 302 and the bottom cover 16, a buffer rubber strip is designed on the edge of the bottom cover 16 to reduce the impact force when the tool falls and extend the service life of the tool.

[0025] like Figure 1 and Figure 4As shown, the control component 1 includes a guide rail 101, a slider 102, a guide rod 103, a control bar 104 and a driving rod 105. The control bar 104 and the guide rod 103 are both arc-shaped, and both ends of the control bar 104 are movably connected to the guide rod 103, and the other end of the guide rod 103 is fixedly connected to the slider 102. The guide rails 101 are symmetrically arranged, and the sliders 102 are respectively slidably connected to the top of the guide rails 101. A thread is provided on the outer side of the driving rod 105, and the driving rod 105 passes through the middle position of the control bar 104, and the driving rod 105 is threadedly connected to the control bar 104. The control component 1 also includes a base 106, and the driving rod 105 is movably connected to the base 106 through a bearing. The control bar 104 is slidably connected to the top of the base 106. A servo motor 6 is fixedly connected to the base 106, and the output end of the servo motor 6 is fixedly connected to the end of the driving rod 105.

[0026] Start the servo motor 106 to drive the driving rod 105 to rotate on the base 106. Since the driving rod 105 is threadedly connected to the control bar 104 and the base 106 limits the moving direction of the control bar 104, the control bar 104 slides on the base 106, and the length direction of the base 106 is consistent with the radial direction of the turntable 12, so that the control bar 104 moves along the radial direction of the turntable 12. Since one end of the guide rod 103 is movably matched with the end of the control bar 104, and the other end of the guide rod 103 is fixedly connected to the slider 102, when the control bar 104 moves close to the turntable 12, under the action of the guide rod 103, the slider 102 moves along the slide rail close to the turntable 12.

[0027] like Figure 1 and Figure 3 As shown, the loading assembly 2 includes a support platform 201, a receiving bin 202, a push block 203 and a cylinder 204. A group of symmetrical receiving bins 202 are fixedly connected to the top of the support platform 201 for placing cutting tools. The interior of the receiving bins 202 are slidably connected to push blocks 203, and the outer sides of the receiving bins 202 are fixedly connected to cylinders 204, and the telescopic ends of the cylinders 204 are fixedly connected to the push blocks 203.

[0028] Several cutting tools are placed in advance on the inside of the accommodating bin 202. A drill is placed on the inside of the accommodating bin 202 on interval two, and a tap is placed on the inside of the accommodating bin 202 on interval three. The push block 203 is controlled by the cylinder 204 to move inside the accommodating bin 202, thereby pushing the cutting tools to move forward inside the accommodating bin 202. An electric-controlled valve is provided at the bottom front side of the accommodating bin 202. When opened, the cutting tools fall vertically into the inside of the accommodating cylinder 303. After closing, the remaining cutting tools can be pushed forward for next replacement.

[0029] like Figure 1 、 Figure 5 and Figure 6As shown, the switching assembly 3 also includes a accommodating box 304, sprocket 1 305, sprocket 2 306 and a chain belt 307. The bottom end of the guide column 301 is fixedly connected to the sprocket 1 305, and the chain belt 307 is sleeved on the outside of the sprocket 1 305 and the sprocket 2 306, and the sprocket 1 305, the sprocket 2 306 and the chain belt 307 constitute a chain transmission structure. The chain belt 307 is movably connected to the inner side of the accommodating box 304, and the sprocket 2 306 is movably connected to the inner side of the accommodating box 304 through a rotating shaft. The clamping blocks 401 are movably passed through the accommodating cylinder 303, and the bottom of the guide column 301 is movably connected to the top of the accommodating box 304. The servo motor 2 7 is fixedly connected to the middle position of the top of the accommodating box 304, and the output end of the servo motor 2 7 is fixedly connected to the top of the rotating shaft of the sprocket 2 306.

[0030] In the initial state, the support plate 302 is parallel to the slide rail, and a single cutting tool is put into the interior of the accommodating cylinder 303 through the loading device, and the interior of the other accommodating cylinder 303 of the support plate 302 is empty. The accommodating box 304 moves forward with the slider 102 until the empty accommodating cylinder 303 moves to the bottom of the drilling device 14 or the tapping device 15, and the axis of the accommodating cylinder 303 coincides with the axis of the old cutting tool. The old tool is released through the drilling device 14 or the tapping device 15, and the old tool falls into the interior of the control accommodating cylinder 303. Then, the servo motor 27 is started to drive the sprocket 2 306 rotates inside the accommodating box 304, causing the chain belt 307 to rotate, controlling the two sprockets 305 to rotate synchronously, thereby causing the two support plates 302 on the top of the accommodating box 304 to rotate synchronously, rotating the accommodating cylinder 303 containing the old tool one hundred and eighty degrees, and rotating the accommodating cylinder 303 containing the new tool to the bottom of the drilling device 14 or the tapping device 15, and then using the drilling device 14 or the tapping device 15 to clamp the new tool, and control the new tool to move upward, so as to facilitate the separation of the new tool from the accommodating cylinder 303, so that the accommodating cylinder 303 can return to its original position.

[0031] like Figure 1 、 Figure 8 and Figure 9As shown, the clamping assembly 4 includes a clamping block 401, a connecting bar 402 and a driving block 403. The clamping blocks 401 are distributed in a circular array. The clamping blocks 401 are each provided with a driving slot 8. The driving slot 8 is arranged obliquely. The interior of the driving slot 8 is movably connected to the driving block 403. The connecting bars 402 are distributed in a circular array. The connecting bars 402 and the driving blocks 403 are arranged in a staggered distribution. The ends of the driving blocks 403 are respectively fixedly connected to the ends of the connecting bars 402. The clamping assembly 4 also includes a connecting rod. 404 and a guide ring 405, the guide ring 405 is movably connected to the outer side of the top end of the guide column 301, and the guide ring 405 is located at the top end of the support plate 302, the outer side of the guide ring 405 is movably connected to a group of symmetrical connecting rods 404 through a rotating shaft, and the other ends of the connecting rods 404 are movably connected to the outer sides of the connecting strips 402 through the rotating shafts, the bottom of the support plate 302 is fixedly connected to an electric push rod 9, and the telescopic end of the electric push rod 9 is fixedly connected to the bottom of the guide ring 405.

[0032] When the new tool or the old tool falls into the accommodating tube 303, the electric push rod 9 is started to control the guide ring 405 to move downward along the guide column 301, driving the connecting rod 404 to rotate, thereby pulling the connecting bar 402 downward along the accommodating tube 303, driving the remaining connecting bars 402 and the driving block 403 to move downward synchronously. Since the driving block 403 and the driving slot 8 are movable, the clamping blocks 401 are pushed closer to each other until the tool is clamped, so that the tool remains in a vertical state, and the axis of the tool coincides with the axis of the accommodating tube 303. At the same time, it is beneficial for the new tool to be able to align with the axis of the mounting head of the drilling device 14 or the tapping device 15 when installing, which is beneficial to improve the accuracy during installation; at the same time, using the clamping block 401 to clamp the tool is beneficial to controlling its stability during movement, and avoiding the tool from colliding with the accommodating tube 303 and being worn when the accommodating tube 303 moves.

[0033] like Figure 1 、 Figure 6 、 Figure 8 and Figure 9 As shown, the opening and closing assembly 5 includes a guide ring 2 501, a connecting rod 2 502 and an electric push rod 2 503. The guide ring 2 501 is movably connected to the outer side of the bottom of the guide column 301. The outer side of the guide ring 2 501 is movably connected to a group of symmetrical connecting rods 2 502 through a rotating shaft, and the other ends of the connecting rods 2 502 are movably connected to the bottom cover 16 through the rotating shaft. The electric push rod 2 503 is fixedly connected to the top of the support plate 302, and the telescopic end of the electric push rod 2 503 is fixedly connected to the top of the guide ring 2 501. The outer side of the bottom cover 16 is fixedly connected to a group of symmetrical guide blocks 10, and the bottom of the support plate 302 is fixedly connected to a group of symmetrical guide bars 11, and the guide blocks 10 are respectively slidably matched with the guide bars 11.

[0034] When the new tool is installed in the accommodating tube 303, the old tool is located inside the accommodating tube 303, and the bottom of the old tool is in conflict with the top of the bottom cover 16. When the accommodating tube 303 is reset away from the turntable 12, the electric push rod 2 503 is started to control the guide ring 2 501 to move downward along the guide column 301, so that the connecting rod 2 502 rotates and the bottom cover 16 is pulled to move close to the guide column 301. The guide block 10 on the side of the bottom cover 16 slides along the guide bar 11 until the bottom cover 16 releases the blocking of the bottom of the accommodating tube 303 and releases the clamping block 401 on the old tool. The old tool falls down and the receiving box is installed on the workbench to store the old tools.

[0035] A method for automatically replacing parts for cutting a shower head connection cover comprises the following steps: During use, when the connection cover on the turntable 12 is processed (for example, after drilling is completed in the drilling section), the drill bit needs to be replaced, or when the tap needs to be replaced in the tapping section, the control system will instruct the automatic replacement device to start. Initially, the cylinder 204 controls the push block 203 to move inside the accommodating chamber 202, thereby pushing the cutting tool forward inside the accommodating chamber 202. An electric control valve is provided at the front bottom of the accommodating chamber 202. When the valve is opened, the cutting tool falls vertically into the interior of the accommodating cylinder 303. Next, when the new or old tool falls into the accommodating tube 303, the electric push rod 9 is activated to control the guide ring 405 to move downward along the guide column 301, driving the connecting rod 404 to rotate, thereby pulling the connecting bar 402 downward along the accommodating tube 303, driving the remaining connecting bars 402 and the driving block 403 to move downward synchronously. Since the driving block 403 and the driving slot 8 are movable, the clamping blocks 401 are pushed closer to each other until the tool is clamped and kept in a vertical state. Then, the servo motor 106 is started to drive the driving rod 105 to rotate on the base 106. Since the driving rod 105 is threadedly connected to the control bar 104 and the base 106 limits the moving direction of the control bar 104, the control bar 104 slides on the base 106, and the length direction of the base 106 is consistent with the radial direction of the turntable 12, so that the control bar 104 moves along the radial direction of the turntable 12. Since one end of the guide rod 103 is movably matched with the end of the control bar 104, and the other end of the guide rod 103 is fixedly connected to the slider 102, when the control bar 104 moves close to the turntable 12, under the action of the guide rod 103, the slider 102 moves along the slide rail close to the turntable 12, so that the empty accommodating cylinder 303 moves to the bottom of the mounting head; Subsequently, the servo motor 2 7 is started, driving the sprocket 2 306 to rotate inside the storage box 304, causing the chain belt 307 to rotate, and controlling the two sprockets 1 305 to rotate synchronously, thereby causing the two support plates 302 on the top of the storage box 304 to rotate synchronously, rotating the storage cylinder 303 containing the old tool 180 degrees, and the storage cylinder 303 containing the new tool is rotated to the bottom of the drilling device 14 or the tapping device 15. The new tool is then clamped by the drilling device 14 or the tapping device 15, and the new tool is controlled to move upward, so that the new tool is separated from the storage cylinder 303, so that the storage cylinder 303 can return to its original position. Finally, the accommodating cylinder 303 is driven to move back through the control component 1. When the accommodating cylinder 303 is reset away from the turntable 12, the electric push rod 2 503 is started to control the guide ring 2 501 to move downward along the guide column 301, so that the connecting rod 2 502 rotates, and at the same time, the bottom cover 16 is pulled to move close to the guide column 301. The guide block 10 on the side of the bottom cover 16 slides along the guide bar 11 until the bottom cover 16 releases the obstruction to the bottom of the accommodating cylinder 303, and at the same time releases the clamping block 401 on the old tool, and the old tool falls downward. The receiving box is installed on the workbench to collect the old tools.

10. The method for automatically replacing parts for cutting a shower head connection cover according to any one of claims 1 to 9, characterized in that: The steps include: S1. During use, when the connection cover on the turntable (12) is processed (for example, after drilling is completed in the drilling section), the drill needs to be replaced or when the tap needs to be replaced in the tapping section, the control system will instruct the automatic replacement device to start. Initially, the cylinder (204) controls the push block (203) to move inside the accommodating chamber (202), thereby pushing the cutting tool forward inside the accommodating chamber (202). An electric control valve is provided at the bottom of the front side of the accommodating chamber (202). When the valve is opened, the cutting tool falls vertically into the interior of the accommodating cylinder (303); S2. Then, when the new tool or the old tool falls into the accommodating tube (303), the electric push rod 1 (9) is started to control the guide ring 1 (405) to move downward along the guide column (301), driving the connecting rod 1 (404) to rotate, thereby pulling the connecting bar (402) downward along the accommodating tube (303), driving the remaining connecting bars (402) and the driving block (403) to move downward synchronously, and because the driving block (403) and the driving slot (8) are movably coordinated, the clamping blocks (401) are pushed closer to each other until the tool is clamped, so that the tool remains in a vertical state; S3. Then, the servo motor 1 (6) is started to drive the driving rod (105) to rotate on the base (106). Since the driving rod (105) is threadedly connected to the control bar (104), and the base (106) limits the moving direction of the control bar (104), the control bar (104) slides on the base (106), and the length direction of the base (106) is consistent with the radial direction of the turntable (12), so that the control bar (104) moves along the radial direction of the turntable (12). Since one end of the guide rod (103) is movably matched with the end of the control bar (104), and the other end of the guide rod (103) is fixedly connected to the slider (102), when the control bar (104) moves close to the turntable (12), under the action of the guide rod (103), the slider (102) moves along the slide rail close to the turntable (12), so that the empty accommodating cylinder (303) moves to the bottom of the mounting head; S4. Subsequently, the servo motor 2 (7) is started to drive the sprocket 2 (306) to rotate inside the accommodating box (304), causing the chain belt (307) to rotate, and the two sprockets 1 (305) are controlled to rotate synchronously, thereby causing the two support plates (302) on the top of the accommodating box (304) to rotate synchronously, rotating the accommodating cylinder (303) containing the old tool by one hundred and eighty degrees, and rotating the accommodating cylinder (303) containing the new tool to the bottom of the drilling device (14) or the tapping device (15), and then using the drilling device (14) or the tapping device (15) to clamp the new tool, and controlling the new tool to move upward, so that the new tool is separated from the accommodating cylinder (303), so that the accommodating cylinder (303) can return to its original position; S5. Finally, the accommodating cylinder (303) is driven to move back by the control component (1). When the accommodating cylinder (303) is reset away from the turntable (12), the electric push rod 2 (503) is started to control the guide ring 2 (501) to move downward along the guide column (301), so that the connecting rod 2 (502) rotates and at the same time pulls the bottom cover (16) to move closer to the guide column (301). The guide block (10) on the side of the bottom cover (16) slides along the guide bar (11) until the bottom cover (16) releases the cover on the bottom of the accommodating cylinder (303) and releases the clamping block (401) on the old tool. The old tool falls downward and a receiving box is installed on the workbench to collect the old tools.
