Description

Technical Field

[0001] This invention belongs to the field of machine tool magazine technology, and specifically relates to a self-testing and stable central tool magazine with lateral tool reversal and its usage method. Background Technology

[0002] Tool magazines, as an important component of automated machine tools, play a vital role in the machining industry. Traditional chain-type tool magazines have complex tool changing mechanisms, requiring intricate combinations and assembly of various components. Furthermore, the chain drive is prone to jamming, affecting the accuracy of tool changing. In addition, traditional chain-type tool magazines lack self-detection functions, often requiring manual shutdown and lubrication, which significantly impacts processing efficiency and increases the workload of workers.

[0003] A search revealed that in the prior art, publication number CN106584179B, published on 2018-11-09, discloses a chain-type tool magazine with a 90° lateral tool reversing function. This includes a frame, a chain mounted on the frame, a chain drive mechanism, a tool reversing mechanism, and a tool changing mechanism. This chain-type tool magazine is a vertical, disc-like tool magazine with high integration, simple structure, stable performance, and ease of production debugging and maintenance. During operation, driven by the chain drive mechanism, the chain drives the tool holder to rotate along a rotary track. When the target tool holder rotates to the reversing position, the roller at the tail of the target tool holder enters the reversing groove. The reversing cylinder drives the reversing block through the reversing pull rod. When the reversing cylinder retracts, the reversing block causes the target tool holder to rotate 90° outward around the tool holder fixing rod. An inductive switch on the reversing cylinder senses the cylinder's engagement and sends a signal, allowing the tool changing mechanism to perform a corresponding rapid tool changing action.

[0004] However, the device still has the following drawbacks: Although it can perform rapid tool changes, it does not have a self-detection function. During the chain transmission of the tool holder, the chain is prone to jamming, which affects the efficiency and accuracy of tool changes. It requires manual shutdown of the equipment and lubrication, which greatly affects processing efficiency and increases the workload of workers. Summary of the Invention

[0014] Furthermore, the calibration mechanism includes a block with an arc-shaped groove. The arc-shaped groove is movably engaged with the tool-carrying mechanism. Two sets of arc-shaped soft pads are arranged inside the arc-shaped groove, with the two sets of arc-shaped soft pads respectively positioned near both ends of the arc-shaped groove. The two sets of arc-shaped soft pads are symmetrically distributed with the central axis of the arc-shaped groove as the center. A pressure sensor is installed at the center of each set of arc-shaped soft pads, and both sets of pressure sensors are in contact with the side wall of the tool-carrying mechanism.

[0015] Furthermore, the lubrication mechanism includes a recovery box, on which a lubrication platform is provided. The lubrication platform is in communication with the interior of the recovery box.

Two sets of annular penetration blocks are sleeved on the lubrication rollers, and the two sets of annular penetration blocks are movably fitted with the cutting mechanism.

[0017] A method for using a self-checking, stable central tool magazine with lateral tool reversal, the method comprising:

[0018] Turn on the electric slide, and the tool changer moves to one side of the machining chamber to remove the tool from the machining chamber;

[0019] At the same time, the conveyor wheel drives the tool transport mechanism to move, transporting the tool to be replaced to the designated position;

[0020] The tool changing mechanism moves to one side of the tool magazine body, clamps the tool to be replaced, and puts the disassembled tool into the tool magazine body;

[0021] The electric slide moves the tool changing mechanism to one side of the machining chamber, and installs the tool to be replaced onto the machining equipment in the machining chamber, thus completing the tool changing operation.

[0022] During the movement of the conveyor wheel and the cutting mechanism, the lubrication mechanism detects the amplitude of the cutting mechanism. When the cutting mechanism jams during the conveying process, the amplitude increases, and the liquid pump is automatically turned on to draw lubricant into the lubrication mechanism to lubricate the cutting mechanism.

[0023] The beneficial effects of this invention are:

[0024] 1. Vibration sensors detect the vibration of the conveyor base. When the tool transport mechanism jams during movement, the vibration amplitude of the conveyor base increases. At this time, the liquid pump is turned on to allow lubricant to flow out through the lubrication mechanism. The tool transport mechanism is automatically lubricated without stopping the machine, which improves the smoothness of the tool transport process, effectively avoids jamming during tool transport, improves the tool changing efficiency of the device, and extends the service life of the device.

[0025] 2. By setting up two sets of annular permeation blocks, the sprayed lubricant overflows through the permeation blocks to lubricate the linkage shaft attached to the permeation blocks, improving the accuracy of lubrication and avoiding lubricant splashing everywhere and causing environmental pollution. During the lubrication process, excess lubricant flows into the recycling box through the lubrication platform for recycling, effectively saving energy.

[0026] 3. By tilting the tool cylinder into the arc-shaped groove, the arc-shaped groove limits its movement and prevents it from shifting. During the rotation of the tool cylinder, it contacts the surfaces of two sets of arc-shaped soft pads, providing cushioning and protection for the tool cylinder. As the tool cylinder rotates, two sets of pressure sensors detect the pressure values ​​generated by the tool cylinder. When the pressure values ​​of the two sets of pressure sensors are the same, that is, when the position of the tool cylinder is parallel to the side wall of the machining chamber, the third cylinder is controlled to close, stopping the pushing operation of the tool cylinder and calibrating the position of the tool cylinder. After the tool cylinder drives the tool to perform a reversing operation, the tool changing mechanism can accurately clamp the reversed tool, effectively improving the stability and accuracy of tool changing.

[0027] 4. The electric slide table drives the first cylinder to move, and the first cylinder adjusts the height of the tool changing mechanism. The tool changing mechanism moves the tool to one side of the tool changing window. The infrared sensor controls the electric door to open, so that the tool changing mechanism can perform tool changing operations on the processing equipment in the processing chamber. The second cylinder adjusts the distance between the tool changing frame and the drive box to facilitate tool clamping and release operations, thereby improving the automation level of the tool changing operation.

Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] This invention provides a self-checking and stable central tool magazine with lateral tool reversal, including a machining chamber 1; for example, such as... Figure 1 As shown.

[0041] A protective net 2 is provided on one side of the processing chamber 1. A tool changing window 101 is opened on one side wall of the processing chamber 1. An electric door 102 is provided on the tool changing window 101. An infrared sensor 103 is provided at the bottom of the inner wall of the tool changing window 101. An electric slide 3 is installed on one side wall of the processing chamber 1. The electric slide 3 is located above the tool changing window 101. The output end of the electric slide 3 is driven to a first cylinder 4. The output end of the first cylinder 4 is driven to a tool changing mechanism 5.

[0042] Specifically, the electric slide 3 drives the first cylinder 4 to move, the first cylinder 4 adjusts the height of the tool changing mechanism 5, the tool changing mechanism 5 moves the tool to one side of the tool changing window 101, and the infrared sensor 103 controls the electric door 102 to open, so that the tool changing mechanism 5 can perform tool changing operation on the processing equipment in the processing chamber 1.

[0043] The tool changing mechanism 5 includes a drive housing 501; for example, such as Figure 2 As shown.

[0044] The top of the drive box 501 is connected to the output end of the first cylinder 4. A second cylinder 502 is installed on one side wall of the drive box 501. The output end of the second cylinder 502 extends into the interior of the drive box 501 and is connected to a motor. The output end of the motor is connected to a reversing shaft 503. One end of the reversing shaft 503 extends to the outside of the drive box 501 and is connected to a tool changer 504. Both ends of the tool changer 504 are equipped with tool change chucks 505.

[0045] Specifically, the distance between the tool changer 504 and the drive box 501 is adjusted by the second cylinder 502 to facilitate the clamping and release of the tool. The tool changer 504 is rotated by the motor, which causes the two sets of tool changer jaws 505 to switch directions, thereby realizing the switching of the tool position.

[0046] For example, such as Figure 3 and Figure 4 As shown.

[0047] A tool magazine body 6 is provided on one side wall of the processing chamber 1. The tool magazine body 6 includes an outer frame 601 and several sets of conveyor wheels 602. Several sets of conveyor grooves are opened on the conveyor wheels 602. Several sets of tool-carrying mechanisms 603 are conveyed on the conveyor wheels 602. Tools are movably engaged on each set of tool-carrying mechanisms 603. A lubrication mechanism 604 is provided between two sets of conveyor wheels 602. The lubrication mechanism 604 is installed on the side wall of the processing chamber 1. The lubrication mechanism 604 is movably attached to the bottom end of the several sets of tool-carrying mechanisms 603. A liquid storage tank 7 is also installed on the side wall of the processing chamber 1. The liquid storage tank 7 stores lubricant. The liquid storage tank 7 is located directly above the tool magazine body 6. A liquid pump is installed on the liquid storage tank 7. The output end of the liquid pump is connected to the lubrication mechanism 604.

[0048] Specifically, the rotating conveyor wheel 602 drives several sets of tool-carrying mechanisms 603 to move in a cycle, so that the required tool is moved to a preset position, which facilitates the tool-changing mechanism 5 to perform tool-changing operation. The liquid pump draws the lubricant in the liquid storage tank 7 into the lubrication mechanism 604, and the lubrication mechanism 604 lubricates the tool-carrying mechanism 603.

[0049] The outer frame 601 has a tool-reversing groove 60101, and a calibration mechanism 8 is provided in the tool-reversing groove 60101. The calibration mechanism 8 is installed on the side wall of the machining chamber 1. A tool-reversing mechanism 9 is installed inside the outer frame 601. The tool-reversing mechanism 9 is movably engaged with a set of tool-carrying mechanisms 603.

[0050] For example, such as Figure 5 As shown.

[0051] The tool transport mechanism 603 includes a transport base 60301. Both sides of the transport base 60301 are provided with linkage shafts 60302. The linkage shafts 60302 are movably engaged with the transport grooves on the transport wheels 602. The other ends of both sets of linkage shafts 60302 are provided with limiting discs 60303. A connecting plate 60304 is sleeved between each pair of adjacent limiting discs 60303. A rotating seat 60305 is provided on the transport base 60301. Both ends of the rotating seat 60305 are provided with rotating shafts 60306. Linkage frames 60307 are sleeved on both sets of rotating shafts 60306. A torsion spring is provided between the linkage frame 60307 and the rotating shaft 60306. A tool cylinder 60308 is mounted on the linkage frame 60307, ​​and the tool cylinder 60308 is movably engaged with a set of tools.

[0052] Specifically, the conveying groove on the conveying wheel 602 is movably engaged with the linkage shaft 60302, so that the conveying wheel 602 can drive the linkage shaft 60302 to move during rotation, thereby realizing the conveying of the tool transport mechanism 603. By setting a torsion spring between the linkage frame 60307 and the rotating shaft 60306, the angle between the linkage frame 60307 and the rotating seat 60305 is maintained as shown in the figure during the movement of the tool transport mechanism 603, that is, the tool cylinder 60308 and the conveying base 60301 are kept perpendicular, which facilitates the conveying of the tool.

[0053] For example, such as Figure 6 As shown.

[0054] The tool reversing mechanism 9 includes a fixed block 901 and a tool reversing gripper 904. A third cylinder 902 is mounted on the fixed block 901. The output end of the third cylinder 902 passes through the fixed block 901 and is connected to a drive block 903. The tool reversing gripper 904 is movably engaged with a set of tool cylinders 60308. A hinge seat 905 is provided on the tool reversing gripper 904. The hinge seat 905 is rotatably connected to the drive block 903.

[0055] Specifically, the third cylinder 902 drives the drive block 903 to move, causing the drive block 903 to drive the reverse tool clamping jaw 904 to clamp a set of tool cylinders 60308. After clamping, the third cylinder 902 drives the drive block 903 to continue moving, causing the tool cylinder 60308 to tilt away from the reverse tool mechanism 9 until the tool cylinder 60308 contacts the calibration mechanism 8, so that the tool changing mechanism 5 can clamp the tool in the tool cylinder 60308, or make it easier for the tool changing mechanism 5 to put the tool into the tool cylinder 60308.

[0056] The calibration mechanism 8 includes a block 801; for example, such as Figure 7 As shown.

[0057] An arc-shaped groove 802 is provided on the block 801. The arc-shaped groove 802 is movably engaged with the cutter barrel 60308. Two sets of arc-shaped soft pads 803 are provided in the arc-shaped groove 802. The two sets of arc-shaped soft pads 803 are respectively located near both ends of the arc-shaped groove 802. The two sets of arc-shaped soft pads 803 are symmetrically distributed with the central axis of the arc-shaped groove 802 as the center. A pressure sensor 804 is installed at the center of each set of arc-shaped soft pads 803. Both sets of pressure sensors 804 are in movable contact with the side wall of the cutter barrel 60308.

[0058] Specifically, by tilting the tool cylinder 60308 into the arc-shaped groove 802, the arc-shaped groove 802 limits its movement and prevents it from shifting. During the rotation of the tool cylinder 60308, it contacts the surfaces of two sets of arc-shaped soft pads 803 respectively, providing buffering and protection for the tool cylinder 60308. As the tool cylinder 60308 rotates, two sets of pressure sensors 804 detect the pressure value generated by the tool cylinder 60308. When the pressure values ​​of the two sets of pressure sensors 804 are the same, that is, when the position of the tool cylinder 60308 is parallel to the side wall of the processing chamber 1, the third cylinder 902 is controlled to close, stopping the pushing operation of the tool cylinder 60308, thereby calibrating the position of the tool cylinder 60308. After the tool cylinder 60308 drives the tool to reverse, the tool changing mechanism 5 can accurately clamp the reversed tool, achieving precise tool changing.

[0059] The lubrication mechanism 604 includes a recovery bin 60401; for example, such as Figure 8 and Figure 9 As shown.

[0060] A lubrication platform 60402 is provided on the recycling bin 60401, and the lubrication platform 60402 is internally connected to the recycling bin 60401. A liquid guide pipe 60403 is provided on one side of the lubrication platform 60402, and the liquid guide pipe 60403 is connected to the output end of the liquid pump. A vibration sensor 60404 is provided on the lubrication platform 60402, and the vibration sensor 60404 is in movable contact with the bottom end of the conveying base 60301. A flow guide groove 60405 is formed on the lubrication platform 60402, and the flow guide groove 60405 is embedded within it. A diversion pipe 60406 is installed in the inlet, and several sets of liquid outlet pipes 60407 are connected to the diversion pipe 60406. The liquid outlet pipes 60407 are provided with liquid outlet holes. Lubricating rollers 60408 are sleeved on the several sets of liquid outlet pipes 60407. Through holes 60409 are provided in the lubricating rollers 60408. The through holes 60409 are movably fitted with the liquid outlet pipes 60407. Two sets of annular permeation blocks 60410 are sleeved on the lubricating rollers 60408. The two sets of annular permeation blocks 60410 are movably fitted with two sets of linkage shafts 60302 respectively.

[0061] Specifically, the vibration sensor 60404 detects the vibration of the conveying base 60301. When the cutting mechanism 603 experiences a jam during movement, the vibration amplitude of the conveying base 60301 increases. At this time, the pump is turned on, allowing lubricant to enter the diversion pipe 60406 through the guide pipe 60403, and then spray out through the outlet holes on several sets of outlet pipes 60407. By setting two sets of annular permeation blocks 60410, the sprayed lubricant overflows through the annular permeation blocks 60410 to lubricate the bottom of the cutting mechanism 603. Excess lubricant flows into the recovery box 60401 through the lubrication table 60402 for recycling. By monitoring the vibration amplitude of the conveying base 60301, the lubrication operation of the cutting mechanism 603 can be easily performed.

[0062] The working principle of the self-checking and stabilizing central tool magazine with lateral tool reversal proposed in this invention is as follows:

[0063] The electric slide 3 drives the first cylinder 4 to move, and the first cylinder 4 adjusts the height of the tool changing mechanism 5. The tool changing mechanism 5 moves the tool to one side of the tool changing window 101. The infrared sensor 103 controls the electric door 102 to open, so that the tool changing mechanism 5 can perform tool changing operation on the processing equipment in the processing chamber 1. The second cylinder 502 adjusts the distance between the tool changing frame 504 and the drive box 501 to facilitate tool clamping and release operations. The motor drives the tool changing frame 504 to rotate, so that the two sets of tool changing jaws 505 change direction, realizing the switching of tool position.

[0064] The conveying wheel 602 is connected to the linkage shaft 60302 via a conveying groove, allowing the linkage shaft 60302 to move as the conveying wheel 602 rotates. This conveys the tool to the tool-carrying mechanism 603, moving the required tool to a preset position for tool changing by the tool-changing mechanism 5. A torsion spring is installed between the linkage frame 60307 and the rotating shaft 60306, ensuring that the angle between the linkage frame 60307 and the rotating seat 60305 remains as shown in the figure during the movement of the tool-carrying mechanism 603. This means that the tool cylinder 60308 and the conveying base 60301 remain perpendicular, facilitating tool delivery.

[0065] The third cylinder 902 drives the drive block 903 to move, causing the drive block 903 to move the reverse tool clamping jaws 904 to clamp a set of tool cylinders 60308. The third cylinder 902 then drives the drive block 903 to continue moving, causing the tool cylinders 60308 to tilt away from the reverse tool mechanism 9 until they tilt into the arc-shaped groove 802. The arc-shaped groove 802 then limits their movement to prevent them from shifting. During the rotation of the tool cylinders 60308, they contact the surfaces of the two sets of arc-shaped soft pads 803, which cushion and protect the tool cylinders 60308. As the tool cylinder 60308 rotates, the two sets of pressure sensors 804 detect the pressure value generated by the tool cylinder 60308. When the pressure values ​​of the two sets of pressure sensors 804 are the same, that is, when the position of the tool cylinder 60308 is parallel to the side wall of the machining chamber 1, the third cylinder 902 is controlled to close, stopping the pushing operation of the tool cylinder 60308, thereby calibrating the position of the tool cylinder 60308. After the tool cylinder 60308 drives the tool to perform a reverse tool operation, the tool changing mechanism 5 can accurately clamp the reversed tool to achieve precise tool changing.

[0066] Vibration sensor 60404 detects the vibration of the conveying base 60301. When the cutting mechanism 603 jams during movement, the vibration amplitude of the conveying base 60301 increases. At this time, the pump is turned on, allowing lubricant to enter the diversion pipe 60406 through the guide pipe 60403, and then spray out through the outlet holes on several sets of outlet pipes 60407. By setting two sets of annular permeation blocks 60410, the sprayed lubricant overflows through the annular permeation blocks 60410 to lubricate the bottom of the cutting mechanism 603. Excess lubricant flows into the recycling box 60401 through the lubrication table 60402 for recycling. By monitoring the vibration amplitude of the conveying base 60301, the lubrication operation of the cutting mechanism 603 can be easily performed.

[0067] Based on the aforementioned self-testing stable central tool magazine with lateral tool reversal, this invention also proposes a method for using the central tool magazine. For example, the method includes:

[0068] The electric slide is activated, the tool changing mechanism moves to one side of the tool changing window, the electric door opens, and the first cylinder drives the tool changing mechanism to move into the machining chamber to remove the tool.

[0069] At the same time, the conveyor wheel drives the tool transport mechanism to move, transporting the tool to be replaced to one side of the tool reversing groove. The third cylinder is activated, and the tool reversing jaws push the tool cylinder, causing the tool cylinder to tilt towards the calibration mechanism.

[0070] Two sets of pressure sensors detect the pressure generated by the cutter barrel. When the pressure values ​​of the two sets of pressure sensors reach the preset value and are the same, the third cylinder is controlled to close.

[0071] The electric slide moves the tool changing mechanism to one side of the tool slot, and opens the tool changing chuck to hold the tool to be replaced;

[0072] Turn on the motor to rotate the tool changer, put the removed tool into the tool barrel, the third cylinder drives the reverse tool chuck to reset, and the conveyor wheel drives the tool transport mechanism to continue moving.

[0073] The electric slide moves the tool changing mechanism to one side of the tool changing window, and installs the tool to be replaced onto the processing equipment in the processing chamber, thus completing the tool changing operation.

[0074] During the process of the conveyor wheel driving the cutting mechanism to move, the conveyor base comes into contact with the vibration sensor, and the amplitude of the cutting mechanism is detected by the vibration sensor;

[0075] When the tool transport mechanism experiences a jam during transport, the amplitude increases, and the liquid pump automatically starts to draw lubricant into the lubrication mechanism to lubricate the tool transport mechanism.

[0076] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
