Description

Technical Field

[0001] This utility model relates to a CNC machine tool with lubrication protection function, and belongs to the field of CNC machine tool technology. Background Technology

[0002] A CNC machine tool is an automated machine tool equipped with a program. The control system can logically process programs with control codes or other symbolic instructions, represent them with coded numbers, input them through an information carrier, and after processing, the CNC device sends out various control signals to control the machine tool's movements, automatically machining parts according to the shape and size required by the drawings.

[0003] The existing patent CN221517103U describes a CNC machine tool with lubrication protection function. This device, in order to achieve more comprehensive cooling and lubrication of the workpiece and tool, incorporates a swing mechanism. When the threaded block drives the spray head to move left and right, it can also swing back and forth, thus widening the contact area between the coolant and the workpiece and tool, resulting in better cooling and lubrication. However, while this device can spray cutting fluid onto the tool and workpiece during back-and-forth movement and left-and-right swinging, the tool can block the sprayed cutting fluid, preventing the workpiece area behind the cutting tool from receiving lubrication and cooling, thus affecting the cooling and lubrication effect of the cutting fluid. Furthermore, although the device includes a reciprocating screw to control the back-and-forth movement of the spray head, it cannot precisely control the liquid spraying to the machining location, and the continuous feed of the tool during machining further affects the lubrication effect at the machining point. Utility Model Content

[0004] The purpose of this invention is to provide a CNC machine tool with lubrication protection function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A CNC machine tool with lubrication protection function includes a machine housing, a cutting motor, and a cutting head. A fixing sleeve is fixedly connected to the inner rear end wall of the machine housing. A rotating liquid guide frame is sealed to the inner side of the fixing sleeve. A folded hose is sealed to the upper front end of the rotating liquid guide frame. A rotating spray pipe is sealed to the front end of the folded hose. The rotating spray pipe is rotatably connected to the rotating liquid guide frame. Telescopic support rods are fixedly connected to the left and right sides of the front end face of the rotating liquid guide frame. A pressure-bearing frame plate is fixedly connected to the front end of the telescopic support rod. A fixing plate is fixedly connected to the upper end of the pressure-bearing frame plate. A transmission push-pull rod is rotatably connected to the rear side of the fixing plate. The transmission push-pull rod is rotatably connected to the rotating spray pipe.

[0007] Furthermore, a cutting motor is provided at the inner center of the rotating liquid guide frame, the cutting motor is fixedly connected to the housing, and a cutting head is fixedly connected to the front end of the output shaft of the cutting motor.

[0008] Furthermore, an injection tube is sealed and connected at the middle position of the upper end of the fixing sleeve.

[0009] Furthermore, a transmission gear is provided on the upper inner side of the rotating liquid guide frame. The transmission gear is rotatably connected to the housing. A driven gear ring is meshed at the upper end of the transmission gear. The driven gear ring is fixedly connected to the rotating liquid guide frame.

[0010] Furthermore, a control motor is fixedly connected to the upper rear end of the chassis, and the output shaft of the control motor is fixedly connected to the transmission gear.

[0011] Furthermore, a spring is provided inside the front tube of the telescopic strut.

[0012] Furthermore, the front end face of the pressure-bearing frame plate is rotatably connected to the upper, lower, left, and right sides with ball bearings.

[0013] The beneficial effects of this utility model are:

[0014] This invention utilizes an injection pipe to inject liquid between a fixed sleeve and a rotating liquid guide frame. This allows cutting fluid to enter the rotating spray pipe through a folded hose, thus lubricating and cooling the cutting tool and the workpiece. The rotation of a control motor drives a transmission gear to rotate a driven gear ring, which in turn rotates the rotating liquid guide frame. This, in turn, causes the rotating spray pipe to rotate and spray around the cutting head, preventing the cutting head from obstructing the cutting fluid and ensuring comprehensive spraying. During cutting, the cutting head continuously advances, causing the pressure frame plate and contact balls to adhere to the workpiece surface and continuously push backward. This causes the fixed plate to drive the transmission push rod to rotate, allowing the rotating spray pipe to rotate along with the cutting head. This ensures precise spraying of the cutting fluid onto the machined area, guaranteeing effective lubrication and cooling of the cutting head and workpiece. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0023] Please refer to Example 1 Figures 1-5 This utility model provides a technical solution:

[0024] A CNC machine tool with lubrication protection function includes a machine housing 1, a cutting motor 10, and a cutting head 11. A fixed sleeve 2 is fixedly connected to the inner rear end wall of the machine housing 1. A rotating liquid guide frame 3 is sealed to the inner side of the fixed sleeve 2. A folded hose 4 is sealed to the upper front end of the rotating liquid guide frame 3. A rotating spray pipe 5 is sealed to the front end of the folded hose 4. The rotating spray pipe 5 is rotatably connected to the rotating liquid guide frame 3. The cutting motor 10 is located at the center of the inner side of the rotating liquid guide frame 3. The cutting motor 10 is fixedly connected to the machine housing 1. The cutting head 11 is fixedly connected to the front end of the output shaft of the cutting motor 10. A liquid injection pipe 12 is sealed to the middle of the upper end of the fixed sleeve 2. A transmission gear 13 is located on the upper inner side of the rotating liquid guide frame 3. The transmission gear 13 is rotatably connected to the machine housing 1. A driven gear ring 14 is engaged with the end of the machine, and the driven gear ring 14 is fixedly connected to the rotating liquid guide frame 3. A control motor 15 is fixedly connected to the upper rear end of the machine housing 1, and the output shaft of the control motor 15 is fixedly connected to the transmission gear 13. By setting the liquid injection pipe 12, liquid can be injected between the fixed sleeve 2 and the rotating liquid guide frame 3, so that the cutting fluid can enter the rotating spray pipe 5 through the folded hose 4, thereby lubricating and cooling the cutting tool and the workpiece. By rotating the control motor 15, the transmission gear 13 can drive the driven gear ring 14 to rotate, thereby rotating the rotating liquid guide frame 3, and thus the rotating spray pipe 5 can rotate and spray around the cutting head 11, thereby avoiding the cutting head 11 from blocking the cutting fluid and affecting the comprehensiveness of the cutting fluid spray.

[0025] Please refer to Example 2 Figure 1 , Figure 2 and Figure 5 The difference between this embodiment and Embodiment 1 is that: Telescopic support rods 6 are fixedly connected to both the left and right sides of the front end face of the rotating liquid guide frame 3; a pressure-bearing frame plate 7 is fixedly connected to the front end of the telescopic support rod 6; a fixing plate 8 is fixedly connected to the upper end of the pressure-bearing frame plate 7; a transmission push-pull rod 9 is rotatably connected to the rear side of the fixing plate 8; the transmission push-pull rod 9 is rotatably connected to the rotating spray pipe 5; a spring 16 is provided inside the front tube of the telescopic support rod 6; and fitting balls 17 are rotatably connected to the upper, lower, left, and right sides of the front end face of the pressure-bearing frame plate 7. This utilizes the... When the cutting head 11 performs cutting on the workpiece, as the cutting head 11 is continuously fed forward, the pressure frame plate 7 and the contact ball 17 can adhere to the surface of the workpiece and continuously squeeze backward, causing the spring 16 to be compressed. This causes the fixed plate 8 to drive the transmission push rod 9 to rotate, which in turn causes the rotating spray pipe 5 to rotate with the feed of the cutting head 11, so that the cutting fluid can be accurately sprayed at the machining position, ensuring the lubrication and cooling spraying effect on the cutting head 11 and the machined workpiece.

[0026] The working principle of this utility model is as follows: During use, the injection pipe 12 injects liquid between the fixed sleeve 2 and the rotating liquid guide frame 3, allowing the cutting fluid to enter the rotating spray pipe 5 through the folded hose 4. This lubricates and cools the cutting tool and the workpiece. The rotation of the control motor 15 causes the transmission gear 13 to drive the driven gear ring 14, which in turn rotates the rotating liquid guide frame 3. This allows the rotating spray pipe 5 to rotate and spray around the cutting head 11, thus preventing the cutting head 11 from directly impacting the cutting surface. The cutting fluid can be obstructed, affecting the overall coverage of the cutting fluid spray. When the cutting head 11 is used to cut the workpiece, as the cutting head 11 is continuously fed, the pressure frame plate 7 and the contact ball 17 can adhere to the workpiece surface and continuously squeeze backward, compressing the spring 16. This causes the fixed plate 8 to drive the transmission push rod 9 to rotate, which in turn causes the rotating spray pipe 5 to rotate with the cutting head 11. This ensures that the cutting fluid can be accurately sprayed at the machined position, guaranteeing the lubrication and cooling spray effect on the cutting head 11 and the machined workpiece.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
