Description

Technical Field

[0001] This utility model relates to the field of single-column vertical lathe technology, specifically a quick tool change device for a single-column vertical lathe. Background Technology

[0002] Vertical lathes are large mechanical equipment used to process large and heavy workpieces with large radial dimensions and relatively small axial dimensions and complex shapes. The spindle of a vertical lathe is vertical and has a circular worktable for mounting the workpiece. The spindle of a vertical lathe can move along the crossbeam guide rail and the tool post guide rail to perform transverse or longitudinal feed. In order to improve productivity and product quality, and reduce scrap rate and cost, CNC vertical lathes have gradually replaced traditional vertical lathes.

[0003] In existing technology, to ensure machining efficiency, current CNC vertical lathes are equipped with tool magazines. The tool magazines are disc-shaped and horizontally positioned. During tool changes, the machine spindle moves along the machine beam towards the tool magazine. To prevent cutting chips from splashing into the tool magazine, an automatically opening and closing protective door is installed between the tool magazine and the worktable. During tool changes, the protective door opens, facilitating the movement of the machine spindle above the tool magazine. Once the machine spindle is above the tool magazine, the tool magazine rotates via a hydraulic motor, aligning the empty tool retraction position on the tool magazine with the tool on the machine spindle. Then, the machine spindle descends and places the tool into the retraction position. After the tool magazine reaches the unloaded position, it automatically rises. Then, the tool magazine rotates again, moving the set tool to directly below the machine tool spindle. Next, the machine tool spindle descends again, clamps the tool, and rises again. Then, the machine tool spindle drives the tool to move along the crossbeam towards the worktable, while the safety door closes. This automatic tool changing method for CNC vertical lathes is slow, which seriously affects machining efficiency. Furthermore, the chips and waste adhering to the spindle can easily fall onto the horizontally set tool magazine, posing a certain safety hazard to the tool magazine. Therefore, it is necessary to improve the quick tool changing device for single-column vertical lathes to solve the above problems. Utility Model Content

[0019] Furthermore, the tool changing assembly 41 includes a first mounting frame 411, which is fixedly connected to the bottom of the mounting plate 1. A first protective frame 412 is fixedly connected to the right side of the first mounting frame 411, and a first motor 413 is fixedly connected to the right side of the first mounting frame 411. The output end of the first motor 413 extends through the first mounting frame 411 and is fixedly connected to a worm gear 414 inside. A worm wheel column 415 is rotatably connected inside the first mounting frame 411. A tool magazine 416 is fixedly connected to the bottom of the worm wheel column 415.

A limit block 418 is fixedly connected to the bottom of the tool sleeves 417, which facilitates the adjustment of the positions of the eight tool sleeves 417, meets the subsequent tool changing operation, shortens the tool changing time when machining on a single-column vertical lathe, and improves machining efficiency.

[0020] Furthermore, the worm 414 meshes with the worm wheel column 415, and eight tool sleeves 417 are provided, which are symmetrically distributed around the center of the tool magazine 416, making the tool changing process more stable.

[0021] Furthermore, the movable component 42 includes a connecting platform 421, which is fixedly connected to the bottom of the hydraulic cylinder 3. A second protective frame 422 is fixedly connected to the right side of the connecting platform 421. A third motor 4210 is fixedly connected to the right side of the connecting platform 421. The output end of the third motor 4210 extends through the connecting platform 421 and is fixedly connected to a threaded rod 425. A limit rod 426 is fixedly connected inside the connecting platform 421. A movable block 427 is slidably connected to the outside of the limit rod 426. A bellows baffle 428 is fixedly connected to the outside of the movable block 427. A second mounting frame 423 is fixedly connected to the bottom of the movable block 427. A second motor 429 is fixedly connected inside the second mounting frame 423. The output end of the second motor 429 extends through the second mounting frame 423 and is fixedly connected to a tool changing arm 424. This facilitates rapid positioning and tool changing on a single-column vertical lathe, while preventing the spindle from directly participating in the tool changing process, which could cause chips and waste adhering to the spindle to fall into the tool magazine 416 and cause jamming or other unexpected situations.

[0022] Furthermore, the movable block 427 is threadedly connected to the threaded rod 425, and the movable block 427 is slidably connected to the connecting table 421, which facilitates a more stable operation. Example

[0023] Based on Example 1, please refer to Figure 5 Furthermore, in conjunction with Embodiment 1, the auxiliary installation mechanism 5 includes an installation bolt 51, which is disposed inside the installation plate 1. A connecting box 52 is fixedly connected to the bottom of the installation plate 1. A spring 53 is fixedly connected inside the connecting box 52. A sliding plate 54 is fixedly connected to the end of the spring 53 away from the connecting box 52. A locking block 55 is fixedly connected to the end of the sliding plate 54 away from the spring 53, which facilitates the adjustment of the position of the locking block 55, thereby limiting the installation bolt 51 and preventing accidents such as loosening during use.

[0024] Furthermore, the slide plate 54 is slidably connected to the connecting box 52, and the locking block 55 is slidably connected to the connecting box 52. The mounting bolt 51 and the locking block 55 are respectively provided with grooves, and the locking block 55 is inserted into the groove, which makes the installation process more stable.

[0025] In actual operation, when this device is used, the threaded rod is a T-type threaded rod to provide self-locking. The operator moves the device to the designated installation position on the single-column vertical lathe. Using the mounting bolt 51, the operator limits the mounting plate 1 to the installation position on the single-column vertical lathe. During installation, the operator pulls the sliding plate 54. The movement of the sliding plate 54, in conjunction with the spring 53, causes the locking block 55 to move. Then, using tools such as a hex wrench, the operator rotates the mounting bolt 51 to lock the mounting plate 1 to the installation position on the single-column vertical lathe. After releasing the sliding plate 54, the locking block 55 engages with the mounting bolt 51 under the action of the spring 53, thus limiting the installation bolt 51 and preventing accidental loosening during use. After limiting, when a tool change operation is required, the movement of the single-column vertical lathe spindle causes the first motor 413 to rotate, rotating the worm gear 414. This, in conjunction with the worm wheel column 415, moves the tool magazine 41. 6. Rotation adjusts the positions of the eight tool holders 417 to facilitate subsequent tool changing operations. After the tool inside the tool holder 417 rotates to the designated position, the third motor 4210 operates, causing the threaded rod 425 to rotate. This, in conjunction with the limit rod 426, moves the movable block 427, thereby adjusting the position of the tool changing arm 424. The tool changing arm 424 is then inserted into the tool inside the tool holder 417, thus limiting the tool position. The hydraulic cylinder 3 operates, causing the tool changing arm 424 to move vertically, allowing the tool inside the tool holder 417 to be removed. The same working principle is used to remove the tool inside the spindle of the single-column vertical lathe. After the two sets of tools are removed, the second motor 429 operates, causing the tool changing arm 424 to rotate, thus exchanging the positions of the two sets of tools. After the exchange, the hydraulic cylinder 3 operates, inserting the exchanged tool into the spindle of the single-column vertical lathe, completing the tool changing operation. Finally, the tool removed from the spindle of the single-column vertical lathe is reinserted into the tool holder 417.

[0026] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
