[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment 1: This embodiment is intended to help solve the problem that the exposed cutter head 28 is likely to cause damage to nearby objects or human beings. Figures 1 to 10 A production auxiliary device for a high-precision CNC lathe includes a main device 1, which includes a base 11. The inner wall of the base 11 is equipped with a clamping device 12 for mounting a workpiece to be processed. The clamping device 12 is installed in the base 11 through a clamping telescopic rod 13. A telescopic protection device 2 is installed on the other side of the base 11.

[0034] The clamping device 12 is used to clamp the workpiece and drive the workpiece to rotate, and the clamping telescopic rod 13 is used to control the movement of the workpiece on the base 11. Through this design, the tool head 28 is driven to process the workpiece (the above structure is the main component for workpiece processing, and its specific structure and working method are existing technologies, so this solution will not be described in detail).

[0035] The telescopic protection device 2 includes a chassis 21 fixedly connected to the inner wall of the base 11, a protective cover 22 is installed on one side of the chassis 21, a mounting block 26 is arranged inside the protective cover 22, a mounting seat 27 is installed above the mounting block 26, a tool head 28 is installed on the outer wall of the mounting seat 27, and a rotating tool changing device 3 is arranged on one side of the chassis 21.

[0036] The protective cover 22 arranged on the outside of the mounting block 26 is used to protect the cutter head 28 installed in the mounting block 26. The mounting block 26 is connected by the electric push rod 25 to form a telescopic design. When processing is not needed, the mounting block 26 is controlled by the electric push rod 25 to drive the mounting block 26 to be retracted inward, so that the protective cover 22 wraps the mounting block 26 to achieve wrapping protection for the cutter head 28, so as to prevent the cutter head 28 exposed to the outside from causing damage to nearby objects or human beings.

[0037] A limiting ring groove 23 is provided in the chassis 21, and a limiting ring block 24 is rotatably connected in the limiting ring groove 23. The other end of the limiting ring block 24 is fixedly connected to a protective sleeve 22. The bottom of the mounting block 26 is fixedly connected to the output end of an electric push rod 25, and the electric push rod 25 is mounted on one side of the chassis 21.

[0038] The rotary tool changing device 3 includes a gear ring 31 fixedly connected to the outer wall of the protective sleeve 22 , the gear ring 31 is meshedly connected to a gear 32 , one side of the gear 32 is fixedly connected to the output end of a drive motor 33 , and the drive motor 33 is installed on one side of the chassis 21 .

[0039] The design of the limiting ring groove 23 and the limiting ring block 24 allows the protective sleeve 22 to rotate in the chassis 21. Through the rotation of the protective sleeve 22, the tool head 28 can be replaced by the rotary tool changing device 3 according to the processing needs, so as to be suitable for different processing. The rotation of the protective sleeve 22 is achieved by the toothed ring 31 and the gear 32 fixedly connected to the outer wall of the protective sleeve 22. The protective sleeve 22 can be driven to rotate by the drive motor 33 and the meshing of the toothed ring 31 and the gear 32.

[0040] A placement groove 34 is provided in the protective cover 22, and a sliding plate 35 is slidably connected in the placement groove 34. A connecting rod 36 is fixedly connected to the bottom of the sliding plate 35, and an adsorption suction cup 37 is fixedly connected to the bottom of the connecting rod 36. A cutter head 28 is adsorbed on the bottom of the adsorption suction cup 37. A telescopic spring 38 is fixedly connected to the top of the sliding plate 35, and the other end of the telescopic spring 38 is fixedly connected in the placement groove 34. A cross groove 39 is provided on the outer wall of the protective cover 22, and a driving folding rod 310 is slidably connected in the cross groove 39. One end of the driving folding rod 310 is fixedly connected to one side of the chassis 21, and the other side of the driving folding rod 310 contacts the sliding plate 35.

[0041] During the rotation of the protective cover 22, the sliding plate 35 located in the protective cover 22 will slide downward under the resistance of the driving folding rod 310. At this time, the adsorption suction cup 37 at the bottom of the sliding plate 35 will slide downward. At this time, the cutter head 28 adsorbed by the adsorption suction cup 37 will slide downward. When the cutter head 28 is installed in the mounting seat 27, the fixing component 4 is driven to fix the cutter head 28 in the mounting seat 27.

[0042] A fixing assembly 4 is provided in the mounting seat 27, and the fixing assembly 4 includes left and right slide grooves 41 opened in the mounting seat 27, and a fixing rod 42 is slidably connected in the left and right slide grooves 41, and a triangular driving block 43 is fixedly connected to one end of the fixing rod 42. The bottom surface of the left and right slide grooves 41 is flush with the top surface of the cutter head 28, and a reset plate 45 is fixedly connected to the bottom of the fixing rod 42. The reset plate 45 is slidably connected in the reset groove 44, and the reset groove 44 is opened in the mounting seat 27. A reset spring 46 is fixedly connected to one side of the reset plate 45, and the other end of the reset spring 46 is fixedly connected in the reset groove 44.

[0043] A driving device 5 is provided on one side of the triangular driving block 43, and the driving device 5 includes a driving circular groove 51 opened in the mounting seat 27, a rotating disk 52 is rotatably connected in the driving circular groove 51, a triangular groove 53 is opened on the outer side wall of one side of the rotating disk 52, a fixed driving gear 54 is fixedly connected to one side of the rotating disk 52, a one-way telescopic driving rod 55 is provided on the side wall of the fixed driving gear 54, the other end of the one-way telescopic driving rod 55 is fixedly connected to the bottom of the sliding plate 35, a one-way groove 56 is opened in the one-way telescopic driving rod 55, a one-way shaft 57 is fixedly connected in the one-way groove 56, a one-way driving block 59 is rotatably connected to the outer side of the one-way shaft 57, and the one-way shaft 57 and the one-way driving block 59 are connected by a torsion spring 58.

[0044] During the downward sliding of the sliding plate 35, the one-way telescopic driving rod 55 slides downward synchronously. Due to the telescopic design of the driving device 5, when the bottom of the one-way telescopic driving rod 55 contacts the fixed driving gear 54, the fixed driving gear 54 will not be driven to rotate temporarily. When the cutter head 28 is installed on the outer wall of the mounting seat 27, the spring in the one-way telescopic driving rod 55 will drive the one-way telescopic driving rod 55 to slide downward and drive the rotating disk 52 to rotate. This design can ensure that the movement of the fixed component 4 starts only after the cutter head 28 is placed in place, ensuring that the fixed component 4 can fix the cutter head 28 on the mounting seat 27. The one-way design in the one-way telescopic driving rod 55 can ensure that the rotating disk 52 The disk 52 can only rotate in one direction. Through the ratio design between the fixed drive gear 54 and the one-way drive block 59, each sliding of the one-way telescopic drive rod 55 will drive the rotating disk 52 to rotate a quarter of a circle. The rotation of the fixed drive gear 54 will drive the rotating disk 52 to rotate. At the same time, the triangular drive block 43 and the fixed rod 42 stuck in the triangular groove 53 on the side wall of the rotating disk 52 will slide outward. At this time, the fixed rod 42 that slides out of the mounting seat 27 will be stuck on the upper surface of the cutter head 28. At this time, the cutter head 28 will not be able to slide because it is stuck by the fixed rod 42. Through this design, the cutter head 28 can be effectively fixed in the mounting seat 27 to ensure the stability of the processing process. After the installation is completed, the protective cover 22 is driven by the drive motor 33 to rotate a small angle, so that the rotary tool changer 3 in the protective cover 22 is separated from the mounting seat 27. At this time, the sliding plate 35 is no longer resisted by the driving folding rod 310, and will slide upward under the action of the telescopic spring 38, and then reset.

[0045] When it is necessary to remove the installed cutter head 28, the protective cover 22 is first rotated in the opposite direction by a certain angle so that the sliding plate 35 is aligned with the cutter head 28. During this process, the sliding plate 35 will slide downward again. At this time, the adsorption suction cup 37 will adsorb the cutter head 28 again, and the one-way telescopic driving rod 55 will drive the rotating disk 52 to rotate again. At this time, the fixing rod 42 will be re-stuck in the triangular groove 53 under the action of the reset spring 46. At this time, the fixing rod 42 no longer restricts the cutter head 28. At this time, the driving motor 33 controls the protective cover 22 to rotate a quarter of a turn. In this process, the sliding plate 35 will slide upward the cutter head 28 adsorbed by the adsorption suction cup 37. At this time, the mounting seat 27 will be in a knife-free state to facilitate the installation of another cutter head 28. Through this design, different cutter heads 28 can be replaced, thereby improving work efficiency.

[0046] Embodiment 2: This embodiment is intended to promote the solution of the problem of poor fixing effect of the fixing component 4. This embodiment is an explanation based on the embodiment 1. For details, please refer to Figures 1 to 10An adsorption fixing device 6 is provided in the mounting seat 27, and the adsorption fixing device 6 includes a pneumatic groove 61 opened in the mounting seat 27, adsorption flexible plates 62 are provided at both ends of the pneumatic groove 61, and adsorption holes 63 are opened in the adsorption flexible plate 62. A piston rod 64 is slidably connected in the pneumatic groove 61, one end of the piston rod 64 is fixedly connected to a piston spring 65, and the other end of the piston spring 65 is fixedly connected to one side of the adsorption flexible plate 62.

[0047] A resistance slide groove 66 is provided in the mounting seat 27, and a pointed resistance block 67 is slidably connected in the resistance slide groove 66. A pointed spring 68 is fixedly connected to the bottom of the pointed resistance block 67, and the other end of the pointed spring 68 is fixedly connected to the pneumatic groove 61. The bottom of the pointed resistance block 67 resists the piston rod 64, and the top of the pointed resistance block 67 resists the rotating disk 52.

[0048] The adsorption and fixing device 6 is used to further improve the fixing effect of the cutter head 28. During the rotation of the rotating disk 52, the adsorption and fixing device 6 will be driven to move synchronously. During the extension of the fixing rod 42, the pointed resistance block 67 originally located at the bottom of the rotating disk 52 will slide upward and be stuck in the triangular groove 53. At this time, the piston rod 64 resisted by the pointed resistance block 67 will slide inward under the action of the piston spring 65. Through this sliding, the air pressure in the pneumatic groove 61 can be driven to decrease, and through the design of the adsorption flexible plate 62, the cutter head 28 installed on the outer surface of the adsorption flexible plate 62 can be adsorbed. Through the adsorption of the cutter head 28 by the adsorption flexible plate 62, the fixing effect of the cutter head 28 can be further improved, and the cutter head 28 can be effectively prevented from being offset during the processing, thereby ensuring the processing quality.

[0049] Embodiment 3: This embodiment is intended to help solve the problem that debris may remain on the surface of the cutter head 28 after processing. This embodiment is an explanation based on Embodiment 2. For details, please refer to Figures 1 to 10 A rotary cleaning device 7 is provided in the sliding plate 35, and the rotary cleaning device 7 includes a ball groove 71 opened in the sliding plate 35, a ball 72 is rotatably connected in the ball groove 71, a mounting rod 73 is fixedly connected to the bottom of the ball 72, and a rotary folding rod 74 is fixedly connected to the top of the ball 72.

[0050] A driving slide groove 75 and a spiral groove 76 are provided in the rotating folding rod 74. A driving slide rod 78 is slidably connected in the driving slide groove 75. A spiral block 77 is fixedly connected to the outer wall of the driving slide rod 78. The spiral block 77 is slidably connected in the spiral groove 76. The top of the driving slide rod 78 is fixedly connected to the top of the placement groove 34.

[0051] The rotary cleaning device 7 is used to clean the debris remaining on the cutter head 28 after processing. During the descending process of the sliding plate 35, the driving slide bar 78 located at the bottom of the sliding plate 35 will slide downward synchronously. During the descending process of the driving slide bar 78, the spiral block 77 fixedly connected to the side wall of the driving slide bar 78 will slide in the spiral groove 76. Through the design of the spiral groove 76 and the spiral block 77, the rotating folding rod 74 rotates with the driving slide bar 78 as the axis, thereby driving the ball 72 fixedly connected to the rotating folding rod 74 to rotate synchronously in the ball groove 71. Through the swing of the ball 72, the mounting rod 73 fixedly connected thereto can be driven to perform a circular motion. Through this design, the cleaning brush installed at the bottom of the mounting rod 73 cleans the tip of the cutter head 28 and cleans the debris remaining at the tip of the cutter head 28, ensuring the cleanliness of the cutter head 28 and preventing the residual debris from affecting the next processing.
