Description

Technical Field

[0001] This utility model relates to the field of CNC drilling technology, and more specifically, to an intelligent CNC drilling machine for deep hole machining. Background Technology

[0002] The intelligent CNC drilling machine for deep hole machining is a high-precision automated device tailored for deep hole machining scenarios. Its core advantages are reflected in its efficient chip removal capability, precise machining control, and wide adaptability.

[0003] However, when existing intelligent CNC drilling machines for deep hole machining are in use, the waste chips generated are discharged by the flow of water in conjunction with the injection of cold water and the rotation speed. However, after being discharged into the waste chip box, the waste chips are prone to collide with the drill rod during the splashing process, which affects the long-term use of the drill rod.

[0004] Therefore, there is an urgent need for an intelligent CNC drilling machine for deep hole machining that can effectively handle waste chips. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an intelligent CNC drilling machine for deep hole machining, so as to solve the technical defects existing in the above-mentioned background technology.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: A smart CNC drilling machine for deep hole machining includes a machine housing, a viewing window hinged to the front surface of the machine housing, and a chip removal system integrated inside the machine housing and linked with the deep hole tool and workpiece fixture. The chip removal system has a movable frame for auxiliary chip removal at its lower part. The chip removal system includes a frame body fastened to the bottom of the machine housing by bolts, a guide bearing seat mounted on the right side of the frame body, a drive end bearing seat on the left side of the frame body and coaxial with the guide bearing seat, a chip removal pipe extending through the lower part of the frame body, and a magnetic suction device horizontally mounted inside the frame body, coaxial with the guide bearing seat and the drive end bearing seat, and distributed in concentric circles. The magnetic attraction device includes a support plate whose two ends are detachably fixed to the inner wall of the frame, a filter plate connected to the support plate and inclined at an angle of ∠30 degrees, and threaded rings evenly distributed on the upper surface of the filter plate.

[0007] With the above-mentioned component settings, when drilling workpieces with the drill rod, the waste chips generated can be attracted by the magnetic attraction device that is distributed in a ring around the drill rod in the chip removal system, thereby reducing the scratches on the drill rod surface caused by the waste chips.

[0008] As a further embodiment of this utility model, the frame also includes a magnetic ring plate and an adsorption ring plate installed on both sides of the inner wall and cooperating with the magnetic attraction device. The magnetic ring plate is connected to the frame with a telescopic bag. One end of the telescopic bag is fixed to the right side of the inner wall of the frame and coaxially corresponds to the guide bearing seat. The other end is sealed to the left end face of the magnetic ring plate and can move and extend with the magnetic ring plate. The surface of the magnetic ring plate is embedded with moving nuts that are evenly distributed in a ring. The side of the telescopic bag that is in contact with the inner wall of the frame has a bushing that passes through a drill rod. A suction tube is connected to the right side of the lower surface of the telescopic bag. The left side of the inner wall of the frame is opposite to the magnetic ring plate. An adsorption ring plate is installed at the appropriate position. The surface of the adsorption ring plate is distributed with drive screws adapted to the moving nut. The part of the drive screw extending out of the frame on the left is connected to a micro drive motor through a flange. With the cooperation of the drive screw and the moving nut, the magnetic ring plate and the adsorption ring plate are adsorbed together under the above-mentioned cooperation, realizing the expansion state of the telescopic bag. This encloses the magnetic suction device with iron filings. With the connection of the suction pipe and the suction pump, the iron filings attached to the surface of the threaded ring are concentratedly sucked up by the suction force. During the suction process, the threaded ring will also shake due to the wind force, thereby helping to shake off the iron filings on the surface.

[0009] As a further embodiment of this utility model, the magnetic ring plate has through holes at the positions corresponding to the telescopic bag and the movable nut, and the hole diameter is adapted to the drive screw.

[0010] As a further embodiment of this utility model, the telescopic bag is a canvas telescopic bag.

[0011] As a further embodiment of this utility model, the magnetic attraction device is coaxially arranged with the magnetic ring plate and the adsorption ring plate, and the magnetic ring plate and the adsorption ring plate have the same diameter, which is larger than the diameter of the magnetic attraction device.

[0012] As a further embodiment of this utility model, the threaded ring is installed radially towards the center of the filter plate, and the threaded ring is made of magnetic material to attract iron filings generated during the processing.

[0013] As a further embodiment of this utility model, the bushing has a gradually tapered structure, with the opening towards the center of the frame being the small end and the opening at the connection point with the bottom of the telescopic bag being the large end. A detachable wiping ring is provided at the small end of the bushing, with its inner ring surface tightly fitting against the surface of the drill rod, assisting in wiping the surface of the drill rod when it is inserted into the frame, and wiping away debris and cutting fluid adhering to its surface when the drill rod is withdrawn from the frame.

[0014] As a further embodiment of this utility model, the movable frame is connected to both the chip removal pipe and the suction pipe, and a suction pump connected to the suction pipe and the chip removal pipe is installed inside the movable frame to realize the centralized collection of waste materials.

[0015] Compared with a traditional intelligent CNC drilling machine for deep hole machining, this utility model has the following advantages: This invention utilizes a magnetic attraction device, a 30° inclined filter screen, and a threaded ring installed towards the center. This allows some iron filings to be attracted by the threaded ring and fall to the bottom of the frame, where they are collected and processed by a chip removal pipe. This reduces the amount of debris splashing inside the frame and causing scratches on the drill rod surface.

[0016] Meanwhile, the telescopic bag can be used to collect iron filings on the surface of the threaded ring, thereby improving the effective recycling of the magnetic suction device. In addition, the suction pipe connected to the telescopic bag is connected to a suction pump. The suction force is used to collect the iron filings attached to the surface of the threaded ring. During the suction process, the threaded ring will also shake due to the wind force, which helps to shake off the iron filings on the surface. Attached Figure Description

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figures 1-7 As shown, this utility model embodiment provides a technical solution for an intelligent CNC drilling machine for deep hole machining: As shown in the figure, an intelligent CNC drilling machine for deep hole machining includes a machine housing 1, a viewing window 2 hinged to the front surface of the machine housing 1, and a chip removal system 3 integrated inside the machine housing 1 and linked with the deep hole tool and workpiece fixture. The chip removal system 3 has a movable frame for auxiliary chip removal at the bottom. The chip removal system 3 includes a frame 31 fastened to the bottom of the machine housing 1 by bolts, a guide bearing seat 32 installed on the right side of the frame 31, a drive end bearing seat 33 located on the same horizontal axis as the guide bearing seat 32 and located on the left side of the frame 31, a chip removal pipe 34 installed through the lower part of the frame 31, and a magnetic suction device horizontally mounted inside the frame 31, coaxial with the guide bearing seat 32 and the drive end bearing seat 33 and distributed in concentric circles. The magnetic attraction device includes a support plate 35 whose two ends are detachably fixed to the inner wall of the frame 31, a filter plate 36 connected to the support plate 35 and inclined at an angle of ∠30 degrees, and threaded rings 37 evenly distributed on the upper surface of the filter plate 36.

[0021] The main structure of this equipment includes a chip removal system that effectively handles the waste chips generated during drilling of workpieces with a drill rod. Utilizing a magnetic suction device arranged in a ring around the drill rod, the waste chips splashed during machining come into contact with the threaded ring 37. The threaded ring 37, being magnetic and having a threaded structure, concentrates and traps the waste chips inside and on its surface. Excess cutting fluid flows out through the filter screen 36, thus separating and collecting iron filings from other debris, while also reducing scratches on the drill rod surface caused by iron filings.

[0022] Specifically, the magnetic attraction device is horizontally mounted inside the frame 31, coaxial with the guide bearing seat 32 and the drive bearing seat 33, and distributed in concentric circles. The magnetic attraction device consists of a support plate 35, a filter plate 36, and a threaded ring 37. The filter plate 36 is inclinedly connected to the support plate 35 at an angle of ∠30°, with the inclination direction facing the center of the circle.

[0023] It should be noted that the tilt direction of the filter plate 36 can be adjusted according to the actual situation, as long as the side with the threaded ring 37 is always facing the drill rod direction.

[0024] To further improve the sustainable use and effective magnetic attraction of the magnetic device inside the frame 31, an adsorption ring plate 313 and a magnetic ring plate 39 are bolted to the left and right sides inside the frame, maintaining the same horizontal axis. A high-precision rolling bearing is installed in the guide bearing seat 32 to guide and support the drill rod. The drive end bearing seat 33 is connected to a miniature drive motor 315 to provide power for the rotation of the drive screw 314. It should be noted that the miniature drive motor 315 can be a synchronous servo motor that supports network communication and precise control, such as STOBER. The EZ series enables multiple micro-drive motors to be programmed via network to start synchronously at a set time. Through the threaded engagement of the drive screw 314 and the moving nut 310, the magnetic ring plate 39 is driven to move axially, and the telescopic bag 38 extends and retracts synchronously, thereby adjusting the distance between the magnetic ring plate 39 and the adsorption ring plate 313. When the telescopic bag 38 is extended to its maximum extent, the magnetic ring plate 39 and the adsorption ring plate 313 adhere to each other and adsorb, thus wrapping the entire magnetic suction device. By using the suction pipe 312 and the suction pump in the moving plate, the iron filings attached to the magnetic suction device wrapped inside the telescopic bag 38 are sucked up and collected. During the suction process, the threaded ring 37 will also shake due to the wind force, thereby helping to shake off the iron filings on the surface.

[0025] Furthermore, in order to facilitate the extension of the telescopic bag 38 under the action of the drive screw 314, the magnetic ring plate 39 is provided with a through hole 391 at a position corresponding to the telescopic bag 38 and the movable nut 310, the diameter of which is adapted to the drive screw 314.

[0026] Among them, the telescopic bag 38 is a canvas telescopic bag. The specific material can be selected according to actual needs, and has the characteristics of wear resistance, good flexibility, oil resistance (adapting to the processing environment), and stable telescopic performance, as the material for the parts that need to be repeatedly stretched and stretched.

[0027] Meanwhile, in order to better and more effectively collect the iron filings adsorbed by the magnetic suction device, the magnetic suction device is coaxially arranged with the magnetic ring plate 39 and the adsorption ring plate 313, and the diameters of the magnetic ring plate 39 and the adsorption ring plate 313 are the same and larger than the diameter of the magnetic suction device, thus further optimizing the collection of iron filings.

[0028] In order to improve the magnetic adsorption device's ability to attract iron filings generated during processing, a threaded ring 37 is installed radially toward the center of the filter plate 36. The threaded ring 37 is made of magnetic material and is used to attract iron filings generated during processing.

[0029] It should be further explained that the bushing 311 has a gradually tapered structure. The opening facing the center of the frame 31 is the small end, and the opening at the connection with the bottom of the telescopic bag 38 is the large end. The small end of the bushing 311 is provided with a detachable wiping ring. Its inner ring surface is in close contact with the surface of the drill rod to assist in wiping the surface of the drill rod when it is inserted into the frame, and to wipe away the debris and cutting fluid adhering to its surface when the drill rod is withdrawn from the frame.

[0030] The movable frame is connected to both the chip removal pipe 34 and the suction pipe 312. The movable frame is equipped with a suction pump that is connected to the suction pipe 312 and the chip removal pipe 34 to achieve centralized collection of waste materials.

[0031] It should be noted that the moving frame also has a component for exporting waste.

[0032] The specific working process of this application is as follows: When performing deep hole machining, the drill rod passes through the guide bearing seat 32, the bushing 311, the magnetic attraction device, the adsorption ring plate 313 and the drive end bearing seat 33, and performs rotary cutting under the drive of the drive motor. The iron filings generated during processing enter the frame 31 with the cutting fluid in conjunction with the drill rod. Under the centrifugal force of the rotating drill rod, the iron filings are thrown out of the drill rod and attracted by the threaded ring 37 of the magnetic attraction device. Excess cutting fluid passes through the filter screen 36 and is thrown out, while some of the iron filings fall down to the frame 31. Through the chip discharge pipe 34 and the connection with the suction pump, they are finally transported to the external chip collection device. Meanwhile, the micro drive motor 315 drives the drive screw 314 to rotate according to the processing requirements. Through the threaded engagement of the screw and the moving nut 310, the magnetic ring plate 39 is pushed to move axially, and the telescopic bag 38 extends and retracts synchronously, so that the adjusting magnetic ring plate 39 and the adsorption ring plate 313 are in contact, thereby realizing the wrapping of the magnetic adsorption device by the telescopic bag 38. Under the suction of the suction tube 312, the iron filings attached to the magnetic adsorption device are absorbed and collected. During the suction process, the threaded ring 37 will also shake due to the wind force, thereby helping to shake off the iron filings on the surface. The tapered structure of bushing 311 facilitates the introduction of the drill rod. The wiping ring cleans the debris and cutting fluid adhering to the surface of the drill rod. The mixture generated during cleaning is pumped to the chip collection device through suction pipe 312 by the suction pump.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
