Numerical control plasma cutting machine controller

Abstract

The utility model relates to the field of numerical control controllers, in particular to a controller of a numerical control plasma cutting machine. The technical problem is that in the operation process of the plasma cutting machine controller, due to the fact that a large amount of dust and tiny scrap iron exist in a cutting workshop and the scrap iron easily enters the controller from a gap of a shell of the controller, the controller breaks down, and if the controller is wrapped by a protective cover to isolate the scrap iron, the controller cannot be damaged. And the heat dissipation of the controller in a high-temperature environment is not facilitated, so that the controller is easy to break down. According to the technical scheme, the numerical control plasma cutting machine controller comprises a protective cooling assembly and a dust and chip filtering assembly. Through the arrangement of the isolation protection mechanism, the cooling mechanism, the double filtering mechanism, the quick core changing mechanism and the damping mechanism, the device can efficiently cool the numerical control plasma cutting machine controller while preventing external small iron chips from entering the numerical control plasma cutting machine controller, so that the probability of faults of the controller is greatly reduced.

Description

Technical Field

[0001] The utility model relates to the field of numerical control controllers, and particularly to a numerical control plasma cutting machine controller. Background Art

[0002] A numerical control plasma cutting machine controller is a device specifically used to control a numerical control machine tool and then control a plasma cutting machine. It is responsible for receiving cutting instructions input by a user and converting these instructions into corresponding action commands to control the numerical control machine tool and then control the movement and cutting process of the cutting machine installed on the numerical control machine tool. However, the environment in the cutting workshop is poor, with a lot of dust and fine iron filings. If these fine iron filings enter the controller interior from the gaps in the controller housing, it is easy for the controller to malfunction. And if the controller is wrapped with a protective cover to isolate the iron filings, it is not conducive to the controller's heat dissipation in a high-temperature environment, which will also make the controller prone to malfunction. Content of the Utility Model

[0003] In order to overcome the problem that during the operation of a plasma cutting machine controller, due to a lot of dust and fine iron filings in the cutting workshop and these iron filings being easy to enter the controller interior from the gaps in the controller housing, causing the controller to malfunction, and if the controller is wrapped with a protective cover to isolate the iron filings, it is not conducive to the controller's heat dissipation in a high-temperature environment, which also easily causes the controller to malfunction.

[0004] The technical solution of the utility model is: a numerical control plasma cutting machine controller, including a protection and cooling component, a dust and chip filtering component, a shock absorption component, and a controller main body; the dust and chip filtering component is arranged at the rear end of the protection and cooling component; the shock absorption component is arranged at the lower end of the dust and chip filtering component; the controller main body is arranged inside the front end of the protection and cooling component.

[0005] Preferably, the protection and cooling component is used to isolate external dust and iron filings and cool the controller main body, the dust and chip filtering component is used to prevent dust and iron filings from entering the interior of the protection and cooling component, the shock absorption component is used to reduce the impact of vibration on the controller main body, and the controller main body is used to control the numerical control machine tool and the plasma cutter.

[0006] Preferably, the protection and cooling component includes a magnetic shielding protective cover, a transparent cover plate, a lifting chute, a magnetizable metal sheet, a first magnet, a semi-wrapped magnetic shielding heat conducting plate, a semiconductor refrigeration chip, an exhaust hood, a backing plate, a fan, and a docking plate; the front end of the upper end surface of the magnetic shielding protective cover is rotatably connected to the transparent cover plate through a hinge; a lifting chute is provided at the front end inside the magnetic shielding protective cover; a magnetizable metal sheet is embedded behind the lower end of the lifting chute; the front end of the magnetizable metal sheet is slidably connected to the first magnet. Place the controller main body into the magnetic shielding protective cover, and attach the semi-wrapped magnetic shielding heat conducting plate to the rear end surface and both sides of the controller main body, and then close the transparent cover plate to isolate dust and iron filings from the outside. Secondly, push the first magnet upward so that the first magnet slides in the lifting chute, and at the same time, the first magnet sucks away the iron filings attached to the front end surface of the controller main body. Subsequently, push the first magnet to the lowest end of the lifting chute and take out the first magnet to clean the iron filings adsorbed on the first magnet, and then reattach the first magnet to the magnetizable metal sheet.

[0007] Preferably, a semi-wrapped magnetic shielding heat conducting plate is fixedly connected to the rear of the upper end of the first magnet; a semiconductor refrigeration chip is fixedly connected to the rear end of the semi-wrapped magnetic shielding heat conducting plate, and the rear end surface of the semi-wrapped magnetic shielding heat conducting plate is in contact with the refrigerating surface of the semiconductor refrigeration chip; an exhaust hood is fixedly connected to the rear end of the magnetic shielding protective cover; a backing plate is fixedly connected to the rear end of the exhaust hood; a fan is fixedly connected to the inside of the exhaust hood; docking plates are fixedly connected to both sides of the exhaust hood. The temperature of the semi-wrapped magnetic shielding heat conducting plate is reduced by the semiconductor refrigeration chip, and then the heat of the controller main body is absorbed by the semi-wrapped magnetic shielding heat conducting plate. At the same time, the fan makes the outside air sequentially pass through two layers of magnetizable metal meshes and a primary filter, and then pass through the exhaust hood. The flowing air will air-cool the heating surface of the semiconductor refrigeration chip when passing through the inside of the exhaust hood, so that while preventing iron filings from entering the CNC plasma cutting machine controller and causing controller failures, the controller can be quickly cooled down.

[0008] Preferably, the dust and chip filtering component includes a first mounting frame, a primary filter, a second mounting frame, a gear column, a horizontal chute, a sliding frame, a tooth groove, a blocking strip, a mounting groove, a second magnet, and a magnetizable metal mesh; the rear end of the fan is communicated with the first mounting frame; the primary filter is slidably connected inside the first mounting frame. When the air passes through the magnetizable metal mesh, because one side of the magnetizable metal mesh is in contact with the second magnet, the magnetizable metal mesh also temporarily has a certain magnetism, so that the iron filings trying to pass through the magnetizable metal mesh are adsorbed on the magnetizable metal mesh, so as to increase the service life of the primary filter. Subsequently, the air will be filtered of dust when passing through the primary filter, so as to prevent dust and iron filings from entering the exhaust hood and adsorbing on the semiconductor refrigeration chip, thereby ensuring the normal operation of the refrigeration mechanism.

[0009] Preferably, two second mounting frames are sequentially connected to the rear end of the first mounting frame; a gear column is rotatably connected to one side inside the second mounting frame; a horizontal chute is formed at the rear end of the gear column.

[0010] Preferably, a sliding frame is slidably connected in the horizontal chute; a tooth groove is formed at the rear end of the sliding frame; a blocking strip is fixedly connected to one side of the rear end of the sliding frame; a mounting groove is formed at the front end of the sliding frame; a second magnet is fixedly connected to one side of the mounting groove; a magnetizable metal mesh is placed in the mounting groove. Since the first mounting frame is slidably connected to the primary filter screen, the primary filter screen can be quickly replaced. When it is necessary to replace or clean the magnetizable metal mesh, the gear column is rotated to expose the sliding frame from the second mounting frame until the blocking strip abuts against one side of the gear column. Then, the magnetizable metal mesh attracted by the second magnet on one side is taken out of the mounting groove, and the iron filings adsorbed on the magnetizable metal mesh are shaken off or a new magnetizable metal mesh is directly replaced, thereby improving the usability of the device.

[0011] Preferably, the shock-absorbing assembly includes docking columns, brackets, supports, and shock absorbers; docking columns are slidably connected to the outer sides of the docking plates; brackets are fixedly connected to the rear ends of the docking columns; supports are fixedly connected to the lower ends of the brackets together; a shock absorber is fixedly connected to the upper end of the support, and the upper end of the shock absorber is fixedly connected to the backing plate. The protection and cooling assembly and the dust and chip filtering assembly are installed and positioned through the docking columns and brackets, and the shock absorber absorbs the impact force generated during vibration, thereby reducing the influence of vibration on the controller body.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. By providing an isolation and protection mechanism, a cooling mechanism, a dual filtration mechanism, a quick filter element replacement mechanism, and a shock-absorbing mechanism, the device can prevent fine iron filings from the outside from entering the CNC plasma cutting machine controller while efficiently cooling it, thereby greatly reducing the probability of failure of the CNC plasma cutting machine controller and allowing the filter element for filtering air to be quickly replaced, thus improving the usability of the equipment.

[0014] 2. Place the controller body inside the magnetic shielding protective cover, and attach the semi-wrapped magnetic shielding heat-conducting plate to the rear end face and both sides of the controller body. Then, close the transparent cover plate to isolate dust and iron filings from the outside. Secondly, push the first magnet upward. While the first magnet slides in the lifting chute, the iron filings attached to the front end face of the controller body are attracted by the first magnet. Subsequently, push the first magnet to the lowest end of the lifting chute and remove the first magnet to clean the iron filings adsorbed on the first magnet. Then, stick the first magnet back onto the magnetizable metal sheet. Additionally, the temperature of the semi-wrapped magnetic shielding heat-conducting plate is reduced by the semiconductor refrigeration chip, and then the heat of the controller body is absorbed by the semi-wrapped magnetic shielding heat-conducting plate. At the same time, the fan allows the outside air to pass through two layers of magnetizable metal meshes and the primary filter in sequence, and then through the exhaust hood. When the flowing air passes through the inside of the exhaust hood, it will air-cool the heating surface of the semiconductor refrigeration chip. Thus, while preventing iron filings from drilling into the CNC plasma cutting machine controller and causing controller failures, the controller can be quickly cooled, providing double protection for the controller;

[0015] 3. When the air passes through the magnetizable metal mesh, since one side of the magnetizable metal mesh is in contact with the second magnet, the magnetizable metal mesh also temporarily has a certain magnetism, so that the iron filings attempting to pass through the magnetizable metal mesh are adsorbed on the magnetizable metal mesh, increasing the service life of the primary filter. Subsequently, when the air passes through the primary filter, dust will be filtered out to prevent dust and iron filings from entering the exhaust hood and adsorbing on the semiconductor refrigeration chip, thus ensuring the normal operation of the refrigeration mechanism;

[0016] 4. Since the first mounting frame is slidably connected to the primary filter, the primary filter can be quickly replaced. When it is necessary to replace or clean the magnetizable metal mesh, turn the gear post to expose the carriage from the second mounting frame until the blocking strip abuts against one side of the gear post. Then, remove the magnetizable metal mesh attracted by the second magnet on one side from the mounting slot, and shake off the iron filings adsorbed on the magnetizable metal mesh or directly replace it with a new magnetizable metal mesh, thus improving the convenience of use of this device;

[0017] 5. The protective cooling component and the dust and iron filings filtering component are installed and positioned through the docking post and the bracket, and the shock absorber absorbs the impact force generated during vibration, thereby reducing the impact of vibration on the controller body.

[0029] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0030] Please refer to Figures 1-5, the present utility model provides an embodiment: a numerical control plasma cutting machine controller, which includes a protection and cooling component 1, a dust and chip filtering component 2, a shock absorption component 3, and a controller main body 4; the dust and chip filtering component 2 is arranged at the rear end of the protection and cooling component 1; the shock absorption component 3 is arranged at the lower end of the dust and chip filtering component 2; the controller main body 4 is arranged inside the front end of the protection and cooling component 1. The protection and cooling component 1 is used to isolate external dust and iron filings and cool the controller main body 4. The dust and chip filtering component 2 is used to prevent dust and iron filings from entering the inside of the protection and cooling component 1. The shock absorption component 3 is used to reduce the impact of vibration on the controller main body 4. The controller main body 4 is used to control the numerical control machine tool and the plasma cutter. The protection and cooling component 1 includes a magnetic shielding protective cover 101, a transparent cover plate 102, a lifting chute 103, a magnetizable metal sheet 104, a first magnet 105, a semi-wrapped magnetic shielding heat conducting plate 106, a semiconductor refrigeration chip 107, an exhaust hood 108, a backing plate 109, a fan 110, and a docking plate 111; the front end of the upper end surface of the magnetic shielding protective cover 101 is rotatably connected to the transparent cover plate 102 through a hinge; a lifting chute 103 is provided at the front end inside the magnetic shielding protective cover 101; a magnetizable metal sheet 104 is embedded behind the lower end of the lifting chute 103; the front end of the magnetizable metal sheet 104 is slidably connected to the first magnet 105. The controller main body 4 is placed into the magnetic shielding protective cover 101, and the semi-wrapped magnetic shielding heat conducting plate 106 is attached to the rear end face and both sides of the controller main body 4, and then the transparent cover plate 102 is closed to isolate external dust and iron filings. Secondly, the first magnet 105 is pushed upward so that while the first magnet 105 slides in the lifting chute 103, the iron filings attached to the front end face of the controller main body 4 are sucked away by the first magnet 105. Subsequently, the first magnet 105 is pushed to the lowest end of the lifting chute 103 and the first magnet 105 is taken out to clean the iron filings adsorbed on the first magnet 105, and then the first magnet 105 is reattached to the magnetizable metal sheet 104. The semi-wrapped magnetic shielding heat conducting plate 106 is fixedly connected to the rear of the upper end of the first magnet 105; the semiconductor refrigeration chip 107 is fixedly connected to the rear end of the semi-wrapped magnetic shielding heat conducting plate 106, and the rear end face of the semi-wrapped magnetic shielding heat conducting plate 106 is in contact with the refrigerating surface of the semiconductor refrigeration chip 107; the exhaust hood 108 is fixedly connected to the rear end of the magnetic shielding protective cover 101; the backing plate 109 is fixedly connected to the rear end of the exhaust hood 108; the fan 110 is fixedly connected to the inside of the exhaust hood 108; the docking plates 111 are fixedly connected to both sides of the exhaust hood 108.The temperature of the semi-wrapped magnetic shielding heat conducting plate 106 is reduced by the semiconductor refrigeration chip 107, and then the semi-wrapped magnetic shielding heat conducting plate 106 absorbs the temperature on the controller body 4. At the same time, the fan 110 enables the outside air to sequentially pass through the two layers of magnetizable metal meshes 211 and the primary filter 202, and then pass through the exhaust hood 108. When the flowing air passes through the inside of the exhaust hood 108, it will air-cool the heating surface of the semiconductor refrigeration chip 107, so that while avoiding iron filings from entering the inside of the numerical control plasma cutting machine controller and causing controller failures, the controller can be quickly cooled down.

[0031] Please refer to Figures 5-10, in this embodiment, the dust and chip filtering assembly 2 includes a first mounting frame 201, a primary filter screen 202, a second mounting frame 203, a gear column 204, a horizontal chute 205, a carriage 206, a tooth groove 207, a blocking strip 208, a mounting groove 209, a second magnet 210, and a magnetizable metal mesh 211; the rear end of the fan 110 is communicated with the first mounting frame 201; the primary filter screen 202 is slidably connected within the first mounting frame 201. When air passes through the magnetizable metal mesh 211, since one side of the magnetizable metal mesh 211 contacts the second magnet 210, the magnetizable metal mesh 211 also temporarily has a certain magnetism, so that iron filings attempting to pass through the magnetizable metal mesh 211 are adsorbed on the magnetizable metal mesh 211, thereby increasing the service life of the primary filter screen 202. Subsequently, when the air passes through the primary filter screen 202, dust will be filtered out to prevent dust and iron filings from entering the exhaust hood 108 and adsorbing on the semiconductor refrigeration chip 107, thus ensuring the normal operation of the refrigeration mechanism. The rear end of the first mounting frame 201 is sequentially communicated with two second mounting frames 203; one side inside the second mounting frame 203 is rotatably connected with a gear column 204; a horizontal chute 205 is opened at the rear end of the gear column 204. A carriage 206 is slidably connected within the horizontal chute 205; a tooth groove 207 is opened at the rear end of the carriage 206; a blocking strip 208 is fixedly connected to one side of the rear end of the carriage 206; a mounting groove 209 is opened at the front end of the carriage 206; a second magnet 210 is fixedly connected to one side of the mounting groove 209; the magnetizable metal mesh 211 is placed within the mounting groove 209. Since the first mounting frame 201 is slidably connected with the primary filter screen 202, the primary filter screen 202 can be quickly replaced. When it is necessary to replace or clean the magnetizable metal mesh 211, the gear column 204 is rotated to expose the carriage 206 from the second mounting frame 203 until the blocking strip 208 abuts against one side of the gear column 204. Subsequently, the magnetizable metal mesh 211 attracted by the second magnet 210 on one side is taken out from the mounting groove 209, and then the iron filings adsorbed on the magnetizable metal mesh 211 are shaken off or a new magnetizable metal mesh 211 is directly replaced, thereby improving the usability of the device; the shock absorption assembly 3 includes a docking column 301, a bracket 302, a support 303, and a shock absorber 304; docking columns 301 are slidably connected to the outside of the docking plate 111; brackets 302 are fixedly connected to the rear ends of the docking columns 301; a support 303 is fixedly connected to the lower ends of the brackets 302 together; a shock absorber 304 is fixedly connected to the upper end of the support 303, and the upper end of the shock absorber 304 is fixedly connected to the backing plate 109. The protection and cooling component 1 and the dust and chip filtering assembly 2 are installed and positioned through the docking columns 301 and the brackets 302, and the shock absorber 304 absorbs the impact force generated during vibration, thereby reducing the influence of vibration on the controller main body 4.

[0032] When working, the user inputs cutting parameters through the operation interface of the controller body 4. The controller body 4 processes these parameters and generates control signals to be transmitted to the numerical control machine tool. The driver of the numerical control machine tool controls the movement of the motor according to the signals to change the position of the plasma cutter, ultimately achieving precise cutting;

[0033] Place the controller body 4 into the magnetic shielding protective cover 101, and let the semi-wrapped magnetic shielding heat conducting plate 106 fit the rear end face and both sides of the controller body 4. Then close the transparent cover plate 102 to isolate external dust and iron filings. Secondly, push up the first magnet 105 so that while the first magnet 105 slides in the lifting chute 103, the iron filings attached to the front end face of the controller body 4 are sucked away by the first magnet 105. Subsequently, push the first magnet 105 to the lowermost end of the lifting chute 103 and take out the first magnet 105 to clean the iron filings adsorbed on the first magnet 105, and then stick the first magnet 105 back onto the magnetizable metal sheet 104;

[0034] In addition, the temperature of the semi-wrapped magnetic shielding heat conducting plate 106 is reduced by the semiconductor refrigeration chip 107, and then the heat of the controller body 4 is absorbed by the semi-wrapped magnetic shielding heat conducting plate 106. At the same time, the fan 110 makes the external air pass through the two layers of magnetizable metal meshes 211 and the primary filter 202 in sequence, and then pass through the exhaust hood 108. When the flowing air passes through the inside of the exhaust hood 108, it will air-cool the heating surface of the semiconductor refrigeration chip 107. Thus, while preventing iron filings from drilling into the numerical control plasma cutter controller and causing controller failures, the controller can be quickly cooled, providing double protection for the controller;

[0035] When the air passes through the magnetizable metal mesh 211, since one side of the magnetizable metal mesh 211 is in contact with the second magnet 210, the magnetizable metal mesh 211 also temporarily has a certain magnetism, so that the iron filings attempting to pass through the magnetizable metal mesh 211 are adsorbed on the magnetizable metal mesh 211, increasing the service life of the primary filter 202. Subsequently, when the air passes through the primary filter 202, the dust will be filtered out to prevent dust and iron filings from entering the exhaust hood 108 and adsorbing on the semiconductor refrigeration chip 107, thus ensuring the normal operation of the refrigeration mechanism;

[0036] Since the first mounting frame 201 is slidably connected to the primary filter 202, the primary filter 202 can be quickly replaced. When it is necessary to replace or clean the magnetizable metal mesh 211, turn the gear post 204 to expose the carriage 206 from the second mounting frame 203 until the blocking bar 208 abuts against one side of the gear post 204. Subsequently, take out the magnetizable metal mesh 211 whose one side is attracted by the second magnet 210 from the mounting groove 209, and then shake off the iron filings adsorbed on the magnetizable metal mesh 211 or directly replace it with a new magnetizable metal mesh 211, thereby improving the usability of the device;

[0037] The protection and cooling assembly 1 and the dust filtering and chip filtering assembly 2 are installed and positioned through the docking column 301 and the bracket 302, and the shock absorber 304 absorbs the impact force generated during vibration, thereby reducing the impact of vibration on the controller main body 4.

[0038] Through the above steps, an isolation protection mechanism, a cooling mechanism, a double filtration mechanism, a quick filter element replacement mechanism, and a shock absorption mechanism are set up, enabling the device to efficiently cool the CNC plasma cutting machine controller while preventing fine iron filings from the outside from entering the interior of the controller, thereby greatly reducing the probability of failure of the CNC plasma cutting machine controller, and allowing the filter element for filtering air to be quickly replaced, thus improving the convenience of use of the equipment.

[0039] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the scope of knowledge possessed by those skilled in the art.
