Description

Technical Field

[0001] This utility model relates to the field of lathe tool magazine technology, specifically a vertical lathe tool magazine structure. Background Technology

[0002] In the field of modern machining, vertical lathes play a crucial role, and the tool magazine, as a key component of vertical lathes, directly affects machining efficiency and accuracy. The hood-type tool magazine, as a common type, has been widely used due to its simple structure and low cost.

[0003] In actual machining processes, the application of the mortise-and-tenon tool magazine in vertical lathes has significant limitations. When tool changing is required, due to its structural design, during parallel tool installation, an empty slot in the tool magazine must first be located, and the tool currently on the tool holder must be removed and placed in the empty slot. Afterward, the tool magazine needs to be rotated and adjusted to move the appropriate tool to the tool holder position before installation. This complex tool-changing process is cumbersome and significantly reduces tool-changing efficiency.

[0004] Therefore, it is necessary to provide a vertical lathe tool magazine structure to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a vertical lathe tool magazine structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A vertical lathe tool magazine structure, comprising:

[0008] A vertical lathe is provided with a machining mechanism. A tool holder is provided at the bottom of the machining mechanism. A cutting tool is provided at the bottom of the tool holder. An electric slide rail is fixedly installed on one side of the machining mechanism on the vertical lathe. A slider is slidably installed on the electric slide rail. A movable frame is fixedly installed at the bottom of the slider. A cover is fixedly installed at the bottom of the movable frame.

[0009] A third motor is fixedly installed inside the movable frame, and the drive end of the third motor passes through the movable frame and the cover in sequence and extends into the interior of the cover. A tool magazine mechanism is provided on the drive end of the third motor, and an auxiliary replacement mechanism is provided on one side of the outer wall of the movable frame.

[0010] Preferably, the tool magazine mechanism includes a tool magazine disc, and the tool magazine disc is fixedly connected to the drive end of the third motor. A plurality of grooves are evenly and equidistantly opened on the outer perimeter of the tool magazine disc. A second tool clip is fixedly installed inside the groove. A slot is provided on one side of the cover.

[0011] Preferably, the auxiliary replacement mechanism includes a mounting frame, which is fixedly mounted on one side of the outer surface of the movable frame. A crossbar is rotatably mounted on the mounting frame. A second motor is fixedly mounted on the top of the mounting frame, and the drive end of the second motor is fixedly connected to the rotating connecting shaft between the crossbar and the mounting frame. One end of the crossbar has a mounting groove, and an electric telescopic rod is fixedly mounted inside the mounting groove. A movable block is fixedly mounted on the drive end of the electric telescopic rod. A rotating rod is rotatably mounted on the bottom of the movable block. A first motor is fixedly mounted on the top of the movable block, and the drive end of the first motor passes through the movable block and extends to the bottom of the movable block, where it is fixedly connected to the top of the rotating rod. A first blade clamp is fixedly mounted on the outer wall of the rotating rod.

[0012] Preferably, one end of the crossbar is provided with a plurality of limiting grooves, and a limiting rod is slidably inserted into the limiting groove, and one end of the limiting rod is fixedly connected to the movable block.

[0013] Preferably, the upper end of the cutting tool is provided with two locking grooves.

[0014] Preferably, the first tool holder is adapted to the upper locking groove of the tool, and the second tool holder is adapted to the lower locking groove of the tool, wherein the locking force of the first tool holder is less than the locking force of the second tool holder.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model utilizes a vertical lathe, machining mechanism, tool holder, cutting tool, movable frame, tool magazine mechanism, and auxiliary changing mechanism in conjunction with each other. During use, with the assistance of the auxiliary changing mechanism, the tool magazine structure allows for the independent disassembly and repositioning of the cutting tool to be replaced. This avoids the cumbersome process of traditional tool magazines, which require finding an empty slot, removing the current cutting tool from the tool holder and placing it in the empty slot, and then rotating and adjusting the tool magazine to move the appropriate cutting tool to the tool holder position for installation. This effectively improves tool changing efficiency and has high practicality.

[0017] 2. This utility model utilizes the combined use of a limiting groove and a limiting rod. When the electric telescopic rod drives the movable block to adjust its lateral position, the limiting rod slides within the limiting groove. The limiting groove applies a limiting constraint to the limiting rod, significantly enhancing the stability of the movable block during lateral movement. This limiting effect effectively reduces the load on the drive end of the electric telescopic rod, minimizing equipment wear and failure risks caused by excessive load, thereby improving the overall stability and reliability of the equipment.

[0027] Please see Figures 1-4 One embodiment provided by this utility model:

[0028] A vertical lathe tool magazine structure, comprising:

[0029] A vertical lathe 1 is provided with a machining mechanism 2. A tool holder 3 is provided at the bottom of the machining mechanism 2. A cutting tool 4 is provided at the bottom of the tool holder 3. An electric slide rail 15 is fixedly installed on one side of the machining mechanism 2 on the vertical lathe 1. A slider 14 is slidably installed on the electric slide rail 15. A movable frame 5 is fixedly installed at the bottom of the slider 14. A cover 10 is fixedly installed at the bottom of the movable frame 5.

[0030] The movable frame 5 is fixedly installed with a third motor 16, and the drive end of the third motor 16 passes through the movable frame 5 and the cover 10 in sequence and extends into the interior of the cover 10. The drive end of the third motor 16 is provided with a tool magazine mechanism, and an auxiliary replacement mechanism is provided on one side of the outer wall of the movable frame 5.

[0031] The tool magazine mechanism includes a tool magazine disc 17, which is fixedly connected to the drive end of the third motor 16. Several grooves 18 are evenly spaced on the outer perimeter of the tool magazine disc 17. A second tool clip 19 is fixedly installed inside the grooves 18. A slot 20 is provided on one side of the cover 10. The slot 20 is provided so that the cover 10 itself does not cause obstruction during the tool magazine mechanism to change the tool 4.

[0032] In one embodiment, the auxiliary replacement mechanism includes a mounting frame 8, which is fixedly mounted on one side of the outer surface of the movable frame 5. A crossbar 9 is rotatably mounted on the mounting frame 8. A second motor 7 is fixedly mounted on the top of the mounting frame 8, and the drive end of the second motor 7 is fixedly connected to the rotatable connecting shaft between the crossbar 9 and the mounting frame 8. A mounting groove 23 is provided at one end of the crossbar 9. An electric telescopic rod 24 is fixedly mounted inside the mounting groove 23. A movable block 13 is fixedly mounted on the drive end of the electric telescopic rod 24. A rotating rod 11 is rotatably mounted on the bottom of the movable block 13. A first motor 6 is fixedly mounted on the top of the movable block 13, and the drive end of the first motor 6 passes through the movable block 13 and extends to the bottom of the movable block 13, where it is fixedly connected to the top end of the rotating rod 11. A first blade clamp 12 is fixedly mounted on the outer wall of the rotating rod 11.

[0033] In one preferred embodiment, a plurality of limiting grooves 21 are provided at one end of the crossbar 9, and limiting rods 22 are slidably inserted into the limiting grooves 21, and one end of the limiting rods 22 is fixedly connected to the movable block 13, thereby improving the stability of the movable block 13 during lateral movement.

[0034] In one embodiment, the upper end of the tool 4 is provided with two locking slots, which facilitates the first tool holder 12 and the second tool holder 19 to lock the tool 4 at different positions, ensuring that the disassembly process is accurate and reliable, and facilitating the efficient replacement of the tool 4.

[0035] In one preferred embodiment, the first tool holder 12 is adapted to the upper locking groove of the tool 4, and the second tool holder 19 is adapted to the lower locking groove of the tool 4. The locking force of the first tool holder 12 is less than that of the second tool holder 19. The adaptation design ensures that the tool holder accurately locks the tool 4. The different locking forces make the disassembly and repositioning of the tool 4 smooth, which facilitates the tool magazine mechanism to efficiently complete the replacement and reset of the tool 4 and improves the operating efficiency of the equipment.

[0036] The working principle of this utility model is as follows: All electrical components mentioned are electrically connected to the main controller and power supply. The main controller can be a computer or other conventionally known control device. Existing publicly available power connection technologies are not detailed here. Parts not mentioned in this device are the same as or can be implemented using existing technologies. In use, when the tool 4 needs to be replaced, the slider 14 is first activated. The slider 14 can move laterally on the electric slide rail 15, causing the movable frame 5 to move synchronously. The movement of the movable frame 5 causes the tool magazine mechanism and the auxiliary replacement mechanism to move laterally together. At this time, through the vertical position adjustment of the processing mechanism 2, the position of the tool 4 at the bottom of the tool holder 3 is adjusted so that the locking groove above the tool 4 is horizontally aligned with the first tool clip 12, and simultaneously, the locking groove below the tool 4 is horizontally aligned with the second tool clip 19 on the tool magazine disc 17. As the auxiliary replacement mechanism moves horizontally, the first tool clip 12 on it will precisely engage in the locking groove above the tool 4. Subsequently, the processing mechanism 2 drives the tool holder 3 to move upward, causing the tool 4 to directly disengage from the tool holder 3. Simultaneously, the second motor 7 is started, and its drive end rotates the crossbar 9. The crossbar 9, through the electric telescopic rod 24, rotates the movable block 13. The movable block 13, through the rotating rod 11, moves the first tool holder 12 and the disassembled tool 4 on it, moving the first tool holder 12 to the rear of the movable frame 5 to avoid affecting the subsequent installation of the tool magazine mechanism for the replacement tool 4. At this time, the drive end of the third motor 16 drives the tool magazine disc 17 to rotate, rotating the tool 4 to be replaced on the tool magazine disc 17 to the slot 20 position for standby. Immediately afterwards, the tool magazine mechanism continues to move laterally, so that the tool 4 to be replaced is under the tool holder 3. At the same time, the tool holder 3 is controlled to move down and directly engage with the tool 4 to be replaced, completing the replacement of the tool 4. Subsequently, the tool magazine mechanism and the auxiliary replacement mechanism are reset, and the machining mechanism 2 can then operate the replaced tool 4 to continue working. When the vertical lathe 1 is in operation, the tool 4 removed from the first tool holder 12 can be rotated by the drive end of the first motor 6, which drives the rotating rod 11 to rotate. The rotating rod 11 drives the first tool holder 12 to rotate, aligning the first tool holder 12 with the slot 20 on the cover 10 and aligning the empty space on the tool magazine disc 17 with the slot 20. At this time, the electric telescopic rod 24 is activated, and its drive end drives the movable block 13 to move laterally. The movable block 13 drives the rotating rod 11 and the first tool holder 12 to move towards the tool magazine disc 17. The tool 4 on the first tool holder 12 is then engaged in the second tool holder 19 inside the groove 18 through the lower engaging slot. Since the engaging force of the first tool holder 12 is less than that of the second tool holder 19, during the reset process of the first tool holder 12, the tool 4 will return to the second tool holder 19 on the tool magazine disc 17, completing the reset of the removed tool 4 on the tool magazine disc 17 for subsequent use.In use, with the assistance of the auxiliary replacement mechanism, this tool magazine structure allows for the independent disassembly and repositioning of the tool 4 to be replaced. This avoids the cumbersome process of traditional tool magazines, which require finding an empty space in the magazine, removing the tool 4 from the current tool holder 3 and placing it in the empty space, and then rotating and adjusting the magazine to move the appropriate tool 4 to the tool holder 3 for installation. This effectively improves the efficiency of tool 4 replacement and has high practicality.

[0037] In use, when the electric telescopic rod 24 drives the movable block 13 to adjust its lateral position, it will cause the limiting rod 22 to slide within the limiting groove 21. The limiting groove 21 applies a limiting constraint to the limiting rod 22, which can significantly enhance the stability of the movable block 13 during lateral movement. This limiting effect can effectively reduce the load on the driving end of the electric telescopic rod 24, reduce equipment wear and failure risks caused by excessive load, and thus improve the stability and reliability of the entire equipment operation.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
