Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] Please see Figure 1-8 In this embodiment of the present invention, a CNC machine tool tool clamping auxiliary device includes an adjusting seat 1, the outer side of which is slidably connected to a plurality of tool clamping devices 2, and the bottom of the adjusting seat 1 is slidably connected to a worktable 3.
[0035] The tool clamping device 2 includes a slide 21. One side of the slide 21 is provided with a dovetail groove 22, which is slidably connected to the dovetail rail 12. The upper surface of the slide 21 is regularly provided with a plurality of tool clamping bolts 23. The lower ends of the plurality of tool clamping bolts 23 are connected to the tool clamping groove 24. The tool clamping groove 24 is provided on the other side of the slide 21. The lower end of the other side of the slide 21 is also symmetrically provided with screw holes 25. The lower surface of the slide 21 is symmetrically provided with slide rails 26.
[0036] The slide rail 26 is slidably connected to the slide groove 27. The slide groove 27 is symmetrically arranged at the lower end of the L-shaped auxiliary clamping seat 28. A connecting seat 29 is symmetrically installed on one side of the L-shaped auxiliary clamping seat 28. Each connecting seat 29 is provided with a fixing bolt 210, which is threadedly connected to the screw hole 25.
[0037] By adopting the above technical solution, when clamping the tool, the cooperation between the tool clamping bolt 23 and the tool clamping groove 24, combined with the auxiliary clamping function of the L-shaped auxiliary clamping seat 28, forms a double clamping structure, which effectively enhances the stability of tool clamping, reduces machining errors caused by tool loosening during the machining process, and improves machining accuracy and product quality.
[0038] In this embodiment, the dovetail rails 12 are arranged in a ring array on the outer side of three sides of the mounting base 11. The bottom of the mounting base 11 is fixedly connected to the base 13. The lower surface of the base 13 is symmetrically provided with sliders 113.
[0039] The slider 113 is slidably connected to the moving rail 32, which is arranged in a rectangular array at the upper end of the slide table 31.
[0040] By adopting the above technical solution, the ring array dovetail rail 12 design allows the tool clamping device 2 to be installed on multiple sides of the adjusting seat 1. Combined with the rectangular array of moving rails 32 on the worktable 3, it can flexibly adapt to the diverse needs of different processing technologies for tool layout, and improve the versatility and processing adaptability of the equipment.
[0041] In this embodiment, the inner side of the mounting base 11 is rotatably connected to the rotating sleeve 14. The inner side of the rotating sleeve 14 is provided with an inner sleeve 15. The upper end of the rotating sleeve 14 is rotatably connected to the upper surface of the mounting base 11, and a rotating sleeve handle 16 is installed on the outer side of the upper end.
[0042] The inner sleeve 15 is connected to the screw 17 on the inner side. The screw 17 passes through the mounting base 11 and the base 13 as a whole, and a fixing block 18 is provided at the bottom. The bottom of the fixing block 18 is movably connected to the moving rail 32.
[0043] The upper end of the screw 17 is threadedly connected to the threaded seat 19, and a threaded seat handle 110 is installed on the outside of the threaded seat 19.
[0044] The lower outer side of the rotating sleeve 14 is regularly provided with multiple protrusions 111. The protrusions 111 are movably connected to one end of the locking block 112. The locking block 112 is regularly provided inside the mounting base 11, and the other end is movably connected to the slide block 21 through the through groove reserved in the mounting base 11 and the dovetail rail 12.
[0045] By adopting the above technical solution, through the sliding cooperation between the slider 113 and the moving rail 32, and the linkage of components such as the threaded seat 19, the screw 17, and the rotating sleeve 14, the position adjustment and height adjustment of the adjusting seat 1 and the tool clamping device 2 can be quickly realized, which can quickly adapt to the installation requirements of different specifications of tools and significantly improve the efficiency of production preparation.
[0046] A dual clamping mechanism is adopted. On the one hand, the cooperation between the locking block 112 and the protrusion 111 at the lower end of the rotating sleeve 14 locks the slide 21. On the other hand, the tool clamping bolt 23 and the L-shaped auxiliary clamping seat 28 work together to ensure that the tool remains stable during the machining process, effectively resist cutting forces and vibrations, and ensure machining accuracy and equipment operation safety.
[0047] The working principle of this utility model is as follows: When using this CNC machine tool clamping auxiliary device, firstly, by sliding the slider 113 at the bottom of the adjusting seat 1 with the moving rail 32, the adjusting seat 1 and the tool clamping device 2 are conveniently moved to the target position on the worktable 3, achieving the initial positioning of the whole; then, the operator rotates the thread seat handle 110, driving the thread seat 19 to rotate. Since the thread seat 19 is threadedly connected to the screw 17, the screw 17 moves axially towards the moving rail 32 during rotation until the fixing block 18 at the bottom of the screw 17 is tightly connected to the moving rail 32, thereby firmly fixing the adjusting seat 1 and the tool clamping device 2 on the worktable 3, completing the overall positioning of the device;
[0048] When clamping and adjusting the tool, first adjust the height of the slide block 21 on the dovetail rail 12 according to the tool specifications; rotate the rotary sleeve handle 16 to drive the rotary sleeve 14 to rotate. When the rotary sleeve 14 is not rotating, the locking block 112 contacts the part of the lower end of the rotary sleeve 14 without the protrusion 111; when the rotary sleeve 14 rotates, the locking block 112 interacts with the protrusion 111 at the lower end of the rotary sleeve 14. Under the push of the protrusion 111, the locking block 112 moves through the through slots reserved in the mounting seat 11 and the dovetail rail 12 to the dovetail groove 22 on the slide block 21, thereby firmly clamping the slide block 21 and preventing it from moving up and down due to vibration and other factors during the machining process;
[0049] When clamping the tool, tightening the tool clamping bolt 23 initially fixes the tool in the clamping groove 24. At the same time, the L-shaped auxiliary clamping seat 28 is connected to the screw hole 25 on the slide 21 by the fixing bolt 210. The slide groove 27 at its lower end slides with the slide rail 26 on the lower surface of the slide 21, which can further assist in clamping the tool and enhance the stability of clamping.
[0050] When clamping the tool, the tool clamping bolt 23 and the tool clamping groove 24 cooperate with the auxiliary clamping function of the L-shaped auxiliary clamping seat 28 to form a double clamping structure, which effectively enhances the stability of tool clamping, reduces the machining error caused by tool loosening during the machining process, and improves machining accuracy and product quality.
[0051] Through the sliding engagement of slider 113 and moving rail 32, and the linkage of components such as threaded seat 19, screw 17, and rotating sleeve 14, the position and height of adjusting seat 1 and tool clamping device 2 can be quickly adjusted, which can quickly adapt to the installation requirements of tools of different specifications and significantly improve production preparation efficiency.
[0052] A dual clamping mechanism is adopted. On the one hand, the cooperation between the locking block 112 and the protrusion 111 at the lower end of the rotating sleeve 14 locks the slide 21. On the other hand, the tool clamping bolt 23 and the L-shaped auxiliary clamping seat 28 work together to ensure that the tool remains stable during the machining process, effectively resist cutting force and vibration, and ensure machining accuracy and equipment operation safety.
[0053] The ring-shaped dovetail rail 12 design allows the tool clamping device 2 to be installed on multiple sides of the adjusting seat 1. Combined with the rectangular array of moving rails 32 on the worktable 3, it can flexibly adapt to the diverse needs of different machining processes for tool layout, improving the equipment's versatility and machining adaptability.
