Description

Technical Field

[0001] This utility model relates to the field of CNC drilling and tapping machine technology, specifically a water spraying device for CNC drilling and tapping machines. Background Technology

[0002] CNC drilling and tapping machines are computer numerical control machine tools that integrate drilling, tapping, and milling functions. They achieve high-precision and automated hole processing operations through programming instructions, processing lightweight aluminum alloy parts such as mobile phone frames, shells, and mid-frames, producing multi-hole hardware, flanges, tube sheets, and precision molds. They also perform efficient drilling and threading of small precision components. By integrating IoT remote monitoring and machine learning parameter self-optimization technology, they enhance their adaptive capabilities and develop dual-spindle and five-axis linkage models to achieve simultaneous processing of multiple workpieces. The water spray device of the CNC drilling and tapping machine is the core part of the cutting fluid delivery system. It is mainly used to cool the tool and workpiece, flush away chips, and lubricate the processing area during processing to improve processing accuracy, extend tool life, and ensure surface quality.

[0003] When using an existing CNC drilling and tapping machine, first open the door, then install and clamp the workpiece, then import or manually write the machining program, then each axis moves and drives the spindle to move to different positions, then the high-speed rotating spindle drives the tool to rotate at high speed to process the workpiece. During processing, ensure that the coolant is supplied normally and clean the chips in time to prevent accumulation from affecting the accuracy.

[0004] Some existing CNC drilling and tapping machines have the following problems: the fixed nozzle cools the machining point and removes debris, and the distance between the nozzle and the machining point is fixed, which can lead to local debris accumulation, resulting in accelerated tool wear and shortened tool life. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a water spraying device for CNC drilling and tapping machines. When using a CNC drilling and tapping machine, the distance between the nozzle and the machining point can be adjusted by extending and retracting the nozzle, so that debris will not accumulate, the tool wear rate will be reduced, and the tool life will be extended, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a CNC drilling and tapping machine water spraying device, including a machining box, a support frame provided on the upper side inside the machining box, and a controller provided on the right side of the front end of the machining box, the input end of the controller being electrically connected to an external power source; It also includes a telescopic mechanism; The telescopic mechanism includes a bracket, a sliding groove, a sliding block, a sliding strip, a turntable, a sliding column, a rotating column, and a protective shell. The lower end of the support frame is provided with a bracket, and the front and rear inner walls of the bracket are respectively provided with sliding grooves. A sliding block is slidably connected between the sliding grooves. A water pipe is provided in the middle of the sliding block, and a nozzle is provided at the right end of the water pipe. A sliding strip is provided at the lower end of the sliding block. A protective shell is provided at the lower end of the bracket. A rotating column is rotatably connected to the bottom wall of the protective shell. A turntable is fixedly connected to the upper end of the rotating column. A sliding column is fixedly connected to the upper edge of the turntable. The outer wall of the sliding column is slidably connected to the inner wall of the sliding strip.

[0007] Furthermore, it provides electrical connections for each electrical appliance.

[0008] Furthermore, the telescopic mechanism also includes a motor, which is located at the lower end of the bracket. The upper end of the motor's output shaft is fixedly connected to the lower end of the rotating column, and the input end of the motor is electrically connected to the output end of the controller to provide telescopic drive.

[0009] Furthermore, a punching machine is provided in the middle of the processing box. The upper left side of the punching machine is fixedly connected to the rear end of the support frame. The input end of the punching machine is electrically connected to the output end of the controller to facilitate punching.

[0010] Furthermore, the left end of the support frame is provided with a water pipe, the lower end of which is connected to the upper end of the water pipe, to facilitate connection to an external water source.

[0011] Furthermore, both the connecting water pipe and the water pipe are PU flexible hoses, providing flexibility.

[0012] Furthermore, the front end of the processing box is slidably connected to a door for easy loading and unloading.

[0013] Compared with the prior art, the beneficial effects of this utility model are: Driven by a motor, the rotating column and turntable cause the sliding column to slide and rotate on the inner wall of the sliding strip, thus converting the circular motion into the horizontal reciprocating motion of the sliding strip. Then, the sliding block slides left and right in the sliding groove in a linear extension and retraction motion. Therefore, the extension and retraction motion of the sliding block directly drives the nozzle to extend and retract synchronously, realizing the adjustment of the distance between the nozzle and the processing point, preventing the accumulation of debris between the nozzle and the processing point. When using a CNC drilling and tapping machine, the distance between the nozzle and the processing point can be adjusted by extending and retracting the nozzle, so that debris will not accumulate, reducing the tool wear rate and extending the tool life.

During the drilling and tapping stages, the spindle motor provides power for drilling and tapping. It is usually equipped with a high-torque servo motor that supports speed adjustment for high-speed drilling and low-speed tapping. During the tapping stage, the spindle switches to a low-speed, high-torque mode, and the tap rotates and cuts into the hole wall to form a thread. (The spindle and Z-axis are strictly synchronized during tapping.) The upper left side of the drilling machine 2 is fixedly connected to the rear end of the support frame 5. The input end of the drilling machine 2 is electrically connected to the output end of the controller 4. The left end of the support frame 5 is provided with a water pipe 6. The lower end of the water pipe 6 is connected to the upper end of the water pipe 7. The front end of the processing box 1 is slidably connected to the box door 3. Both the water pipe 6 and the water pipe 7 are PU hoses.

[0018] This also includes a telescopic mechanism 9; the telescopic mechanism 9 includes a bracket 91, a sliding groove 92, a sliding block 93, a sliding strip 94, a turntable 95, a sliding column 96, a rotating column 97, and a protective shell 98. The lower end of the support frame 5 is provided with a bracket 91. Sliding grooves 92 are respectively opened on the front and rear inner walls of the bracket 91. A sliding block 93 is slidably connected between the sliding grooves 92. A water pipe 7 is provided in the middle of the sliding block 93, and a nozzle 8 is provided at the right end of the water pipe 7. A sliding strip 94 is provided at the lower end of the sliding block 93. The bracket 91... The lower end is provided with a protective shell 98, the bottom wall of the protective shell 98 is rotatably connected to a rotating column 97, the upper end of the rotating column 97 is fixedly connected to a turntable 95, the upper edge of the turntable 95 is fixedly connected to a sliding column 96, the outer wall of the sliding column 96 is slidably connected to the inner wall of the sliding strip 94; the telescopic mechanism 9 also includes a motor 99, the motor 99 is set at the lower end of the bracket 91, the upper end of the output shaft of the motor 99 is fixedly connected to the lower end of the rotating column 97, and the input end of the motor 99 is electrically connected to the output end of the controller 4.

[0019] The working principle of this utility model is as follows: When using a CNC drilling and tapping machine, first push the door 3 to the left to place the workpiece on the fixture, then fix the workpiece on the fixture, then close the door 3, then operate the drilling machine 2 by controlling the controller 4, and the drilling machine 2 will perform drilling work on the workpiece. Next, connect an external cleaning water source with a certain water pressure through the connecting water pipe 6, or connect an external water pump to ensure that the nozzle 8 can spray water normally. Then, operate the water pump by controlling the controller 4, and the water pump will spray water from the nozzle 8 through the connecting water pipe 6 and water pipe 7. Then, motor 99 operates, and its output shaft drives rotating column 97 to rotate. This, in turn, drives turntable 95 to rotate synchronously. Sliding column 96 on the edge of turntable 95 moves in a circular motion with turntable 95. (Initially, turntable 95 drives sliding column 96 to the 12 o'clock position inside sliding bar 94. Then, when turntable 95 drives sliding column 96 to the 3 o'clock position, the outer surface of sliding column 96 slides against the left side of sliding bar 94, thus moving sliding block 93 to the right within sliding groove 92. When turntable 95 drives sliding column 96 to the 9 o'clock position, the outer surface of sliding column 96 slides against the right side of sliding bar 94, thus...) (The sliding block 93 moves to the left inside the sliding groove 92). Since the sliding column 96 is embedded in the inner wall of the sliding strip 94 and can slide relative to it, the circular motion is converted into the horizontal reciprocating motion of the sliding strip 94. The sliding strip 94 is fixedly connected to the sliding block 93, and the sliding block 93 slides linearly in the left and right directions inside the sliding groove 92. Therefore, the reciprocating motion of the sliding strip 94 drives the sliding block 93 to make linear extension and retraction motion along the sliding groove 92. The water pipe 7 is fixed in the middle of the sliding block 93, and the nozzle 8 is connected to the right end of the water pipe 7. Therefore, the extension and retraction motion of the sliding block 93 directly drives the nozzle 8 to extend and retract synchronously, realizing the adjustment of the distance between the nozzle 8 and the processing point, and preventing the accumulation of debris between the nozzle 8 and the processing point.

[0020] It is worth noting that the drilling machine 2 and the motor 99 disclosed in the above embodiments, the drilling machine 2 can be a CX-640 drilling and tapping center, the motor 99 can be a 35BYJ412H, and the controller 4 controls the operation of the drilling machine 2 and the motor 99 using methods commonly used in the prior art.
