Description

Technical Field

[0001] The invention relates to the technical field of numerical control machining machines, in particular to a numerical control machining machine for cylindrical workpieces. Background Art

[0002] CNC machine tools are machine tools that use digital information to achieve automatic control. It uses codes composed of specified words, numbers and symbols to compile information related to the processed parts (the dimensional parameters of the relative motion trajectory between the workpiece and the tool, the process parameters of the cutting process, and various auxiliary operations and other processing information) into a processing program in a certain format, and then inputs it into the CNC device through the control medium. After analysis and processing, the CNC device sends out various signals and instructions corresponding to the processing program for automatic processing;

[0003] At present, traditional CNC machining machines mostly fix square workpieces when fixing workpieces. When it is necessary to fix cylindrical workpieces, the original cylindrical fixing fixtures lose their function, and the debris during the processing is easy to fall into the gap of the machine tool body. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a CNC machining machine for cylindrical workpieces, which solves the problem that traditional CNC machining machines mostly fix square workpieces when fixing workpieces, and when the cylindrical workpiece needs to be fixed, the original cylindrical fixing fixture loses its function, and the debris during the machining process is easy to fall into the gap of the machine tool body.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: it includes a machine tool body, a mobile frame is movably installed on the surface of the machine tool body, a material frame is fixedly installed on the upper surface of the mobile frame, a clamping mechanism is arranged on the upper surface of the material frame, the clamping mechanism includes a fixed cylinder, the fixed cylinder is fixedly connected to the surface of the material frame, an elastic sheet is fixedly installed on the surface of the fixed cylinder, a first magnetic block is fixedly installed on the surface of the elastic sheet, a positioning rod is slidably installed on the inner wall of the fixed cylinder, and an insulating magnetic column is fixed on the surface of the positioning rod.

[0006] Preferably, four circumferentially equidistantly distributed elastic bars are fixedly installed on the surface of the insulating magnetic column, and one end of the elastic bar away from the insulating magnetic column is fixedly connected to the inner wall of the fixed cylinder. When fixing the workpiece, the cylindrical workpiece is inserted into the fixed cylinder and the workpiece is pressed in the direction close to the material rack. The workpiece drives the insulating magnetic column to move through the positioning rod, and the insulating magnetic column stretches the elastic bar to generate elastic force. When the insulating magnetic column is inserted into the material rack, the restriction between the first magnetic blocks is lost, and the magnetic force between the first magnetic blocks drives the elastic sheets to approach each other. The elastic sheets fix the workpiece during the movement, and the elastic sheets can fix cylindrical workpieces of different diameters.

[0007] Preferably, a cleaning component is provided on the surface of the movable frame, and the cleaning component includes an airbag, which is fixedly connected to the surface of the movable frame, and the airbag is arranged directly below the magnetic-insulating column. A nozzle is fixedly installed on the surface of the airbag, and the number of the nozzles is two and they are symmetrically arranged. A second magnetic block is fixedly installed on the lower surface of the magnetic-insulating column.

[0008] Preferably, a fixing plate is fixedly installed on the inner top wall of the airbag, and the fixing plate is adapted to the second magnetic block. When the magnetic column moves, it drives the second magnetic block to squeeze the airbag, and the air in the airbag contracts and is ejected along the nozzles on both sides. The ejected air blows out the debris between the mobile rack and the material rack, thereby ensuring the cleanliness between the mobile rack and the material rack, and when the second magnetic block is reset, the magnetism drives the fixing plate to move, and the movement of the fixing plate drives the airbag to recover, thereby facilitating cleaning next time.

[0009] Preferably, a collecting and filtering assembly is provided on the surface of the machine tool body, and the collecting and filtering assembly includes a plurality of nozzles, and the nozzles are fixedly connected to the surface of the machine tool body. A rotating roller is rotatably installed on the surface of the machine tool body, and a filter screen is fixedly installed on the surface of the rotating roller. The number of the filter screens is six and they are distributed circumferentially on the surface of the rotating roller.

[0010] Preferably, a collection box is provided directly below the machine tool body, and the collection box is adapted to the filter. When cleaning debris in the gaps on the surface of the machine tool body, water is passed through the nozzle, and the water sprayed from the nozzle carries the debris toward the direction close to the filter. When the water flow mixed with debris drives the filter and the rotating roller to rotate, the debris in the water flow will be blocked by the filter, and when the filter rotates to a certain angle, the debris will fall into the collection box, thereby cleaning and collecting the debris in the gaps of the machine tool body, preventing the debris from staying in the gaps of the machine tool body for a long time, causing friction between the debris and the movable frame.

[0011] Preferably, an auxiliary component is provided on the surface of the nozzle, and the auxiliary component includes a mounting block, the mounting block is fixedly connected to the surface of the nozzle, a baffle is rotatably mounted on the surface of the mounting block, the baffle abuts against the surface of the nozzle, a scraper rod is fixedly mounted on the surface of the baffle, and the scraper rod abuts against the inner wall of the nozzle.

[0012] Preferably, an elastic member is fixedly installed on the surface of the baffle, and one end of the elastic member away from the baffle is fixedly connected to the surface of the nozzle. When the nozzle sprays water, the baffle is driven to rotate, and the elastic member is squeezed when the baffle rotates. The water flow and the baffle cooperate to change the direction of the water flow, so that the water flow can flush the blind area directly below the nozzle. When the water flow stops, the elastic member drives the baffle to reset. When the baffle is reset, it drives the scraper rod to clean up the dirt at the nozzle mouth of the nozzle, so as to prevent the sealing of the baffle from being destroyed and impurities from entering the nozzle.

[0013] The present invention provides a cylindrical workpiece CNC machining machine tool, which has the following beneficial effects:

[0014] (I) The cylindrical workpiece CNC machining machine tool fixes the workpiece by means of a clamping mechanism. The cylindrical workpiece is inserted into a fixing tube and the workpiece is pressed toward a material rack. The workpiece drives the magnetic-insulating column to move through a positioning rod. The magnetic-insulating column stretches the elastic strip to generate elastic force. When the magnetic-insulating column is inserted into the material rack, the restrictions between the first magnetic blocks are removed. The magnetic force between the first magnetic blocks drives the elastic sheets to approach each other. The elastic sheets fix the workpiece during movement, and the elastic sheets can fix cylindrical workpieces of different diameters.

[0015] (ii) The cylindrical workpiece CNC machining machine, through the cleaning component provided, when the magnetic column moves, drives the second magnetic block to squeeze the airbag, the airbag contracts and the air inside it is ejected along the nozzles on both sides, the ejected air blows out the debris between the moving frame and the material frame, thereby ensuring the cleanliness between the moving frame and the material frame, and when the second magnetic block is reset, the magnetism drives the fixed plate to move, and when the fixed plate moves, it drives the airbag to recover, thereby facilitating the next cleaning.

[0016] (III) The cylindrical workpiece CNC machining machine, through the set collection and filtering assembly, cleans the debris in the gaps on the surface of the machine body, and passes water through the nozzle. The water sprayed from the nozzle carries the debris toward the filter screen. When the water flow mixed with debris drives the filter screen and the rotating roller to rotate, the debris in the water flow will be blocked by the filter screen, and when the filter screen rotates to a certain angle, the debris will fall into the collection box, thereby cleaning and collecting the debris in the gaps of the machine body, preventing the debris from being in the gaps of the machine body for a long time, causing friction between the debris and the moving frame.

[0017] (IV) The cylindrical workpiece CNC machining machine, through the auxiliary components, when the nozzle sprays water, drives the baffle to rotate, and the baffle rotates to squeeze the elastic member. The water flow and the baffle cooperate to change the direction of the water flow, so that the water flow can flush the blind area directly below the nozzle. When the water flow stops, the elastic member drives the baffle to reset. When the baffle is reset, it drives the scraper to clean the dirt at the nozzle mouth of the nozzle, so as to prevent the sealing of the baffle from being damaged and impurities from entering the nozzle.

[0027] Among them, four circumferentially equidistantly distributed elastic bars 46 are fixedly installed on the surface of the magnetic-insulating column 45, and one end of the elastic bar 46 away from the magnetic-insulating column 45 is fixedly connected to the inner wall of the fixed cylinder 41. When fixing the workpiece, the cylindrical workpiece is inserted into the fixed cylinder 41, and the workpiece is pressed in the direction close to the material rack 3. The workpiece drives the magnetic-insulating column 45 to move through the positioning rod 44, and the magnetic-insulating column 45 stretches the elastic bar 46 to generate elastic force. When the magnetic-insulating column 45 is inserted into the material rack 3, the restrictions between the first magnetic blocks 43 are lost, and the magnetic force between the first magnetic blocks 43 drives the elastic sheets 42 to approach each other. The elastic sheets 42 fix the workpiece during the movement, and the elastic sheets 42 can fix cylindrical workpieces of different diameters.

[0028] Among them, a cleaning component 5 is provided on the surface of the movable frame 2, and the cleaning component 5 includes an airbag 52, which is fixedly connected to the surface of the movable frame 2, and is arranged directly below the magnetic-insulating column 45. A nozzle 53 is fixedly installed on the surface of the airbag 52, and the number of the nozzles 53 is two and they are symmetrically arranged. A second magnetic block 51 is fixedly installed on the lower surface of the magnetic-insulating column 45.

[0029] Among them, a fixing plate 54 is fixedly installed on the inner top wall of the airbag 52, and the fixing plate 54 is adapted to the second magnetic block 51. When the magnetic column 45 moves, it drives the second magnetic block 51 to squeeze the airbag 52. The airbag 52 contracts and the air inside it is ejected along the nozzles 53 on both sides. The ejected air blows out the debris between the mobile rack 2 and the material rack 3, thereby ensuring the cleanliness between the mobile rack 2 and the material rack 3, and when the second magnetic block 51 is reset, the magnetism drives the fixing plate 54 to move, and when the fixing plate 54 moves, it drives the airbag 52 to recover, thereby facilitating cleaning next time.

[0030] Among them, a collecting and filtering assembly 6 is arranged on the surface of the machine tool body 1, and the collecting and filtering assembly 6 includes a plurality of nozzles 61, and the nozzles 61 are fixedly connected to the surface of the machine tool body 1. A rotating roller 62 is rotatably installed on the surface of the machine tool body 1, and a filter screen 63 is fixedly installed on the surface of the rotating roller 62. There are six filter screens 63 and they are distributed circumferentially on the surface of the rotating roller 62.

[0031] Among them, a collection box 64 is arranged directly below the machine tool body 1, and the collection box 64 is adapted to the filter screen 63. When cleaning the debris in the gaps on the surface of the machine tool body 1, water is passed through the nozzle 61, and the water sprayed from the nozzle 61 carries the debris to move in the direction close to the filter screen 63. When the water flow mixed with debris drives the filter screen 63 and the rotating roller 62 to rotate, the debris in the water flow will be blocked by the filter screen 63, and when the filter screen 63 rotates to a certain angle, the debris will fall into the collection box 64, thereby cleaning and collecting the debris in the gaps of the machine tool body 1, preventing the debris from being in the gaps of the machine tool body 1 for a long time, causing friction between the debris and the movable frame 2.

[0032] Among them, an auxiliary component 7 is provided on the surface of the nozzle 61, and the auxiliary component 7 includes a mounting block 71, which is fixedly connected to the surface of the nozzle 61, and a baffle 72 is rotatably installed on the surface of the mounting block 71, and the baffle 72 abuts against the surface of the nozzle 61, and a scraper rod 73 is fixedly installed on the surface of the baffle 72, and the scraper rod 73 abuts against the inner wall of the nozzle 61.

[0033] Among them, an elastic member 74 is fixedly installed on the surface of the baffle 72, and one end of the elastic member 74 away from the baffle 72 is fixedly connected to the surface of the nozzle 61. When the nozzle 61 sprays water, it drives the baffle 72 to rotate. When the baffle 72 rotates, it squeezes the elastic member 74. The water flow and the baffle 72 cooperate to change the direction of the water flow, so that the water flow can flush the blind area directly below the nozzle 61. When the water flow stops, the elastic member 74 drives the baffle 72 to reset. When the baffle 72 resets, it drives the scraper 73 to clean up the dirt at the pipe mouth of the nozzle 61 to prevent the sealing of the baffle 72 from being destroyed and impurities from entering the nozzle 61.

[0034] During operation, when fixing the workpiece through the clamping mechanism 4, the cylindrical workpiece is inserted into the fixing tube 41, and the workpiece is pressed toward the direction close to the material rack 3. The workpiece drives the magnetic-insulating column 45 to move through the positioning rod 44. The magnetic-insulating column 45 stretches the elastic strip 46 to generate elastic force. When the magnetic-insulating column 45 is inserted into the material rack 3, the restrictions between the first magnetic blocks 43 are lost. The magnetic force between the first magnetic blocks 43 drives the elastic sheets 42 to approach each other. The elastic sheets 42 fix the workpiece during the movement, and the elastic sheets 42 can fix cylindrical workpieces of different diameters.

[0035] Through the cleaning component 5, the magnetic column 45 drives the second magnetic block 51 to squeeze the airbag 52 when it moves. The airbag 52 contracts and the air inside it is ejected along the nozzles 53 on both sides. The ejected air blows out the debris between the mobile rack 2 and the material rack 3, thereby ensuring the cleanliness between the mobile rack 2 and the material rack 3. When the second magnetic block 51 is reset, the magnetism drives the fixed plate 54 to move, and the fixed plate 54 moves to drive the airbag 52 to recover, thereby facilitating cleaning next time.

[0036] When cleaning the debris in the gaps on the surface of the machine tool body 1 through the set collection and filtering component 6, water is passed through the nozzle 61, and the water sprayed from the nozzle 61 carries the debris to move in the direction close to the filter screen 63. When the water flow mixed with debris drives the filter screen 63 and the rotating roller 62 to rotate, the debris in the water flow will be blocked by the filter screen 63, and when the filter screen 63 rotates to a certain angle, the debris will fall into the collection box 64, thereby cleaning and collecting the debris in the gaps of the machine tool body 1, preventing the debris from staying in the gaps of the machine tool body 1 for a long time, causing friction between the debris and the movable frame 2.

[0037] By means of the auxiliary component 7, when the nozzle 61 sprays water, the baffle 72 is driven to rotate, and the baffle 72 squeezes the elastic member 74 when rotating. The water flow cooperates with the baffle 72 to change the direction of the water flow, so that the water flow can flush the blind area directly below the nozzle 61. When the water flow stops, the elastic member 74 drives the baffle 72 to reset. When the baffle 72 resets, it drives the scraper 73 to clean the dirt at the nozzle mouth of the nozzle 61, so as to prevent the sealing of the baffle 72 from being damaged and impurities from entering the nozzle 61.
