Description

Technical Field

[0001] The present invention relates to the technical field of numerical control machine tools, and more particularly to a workbench for a numerical control machine tool. Background Art

[0002] A numerical control machine tool is short for a numerically controlled machine tool, which is usually composed of a control system, a servo system, a detection system, a mechanical transmission system and other auxiliary systems. The control system is used for the operation, management and control of the numerical control machine tool. It obtains data through an input medium, interprets and operates on these data and acts on the machine tool. The servo system drives the machine tool according to the instructions of the control system, so that the tool and the part execute the movement specified by the numerical control code. The detection system is used to detect the displacement and speed change of the machine tool actuator, and feedback the detection result to the input end, compare it with the input instruction, and adjust the machine tool movement according to the difference. The machine tool transmission system is a mechanical feed transmission device between the feed servo drive element and the machine tool actuator. The auxiliary systems are various, including an automatic tool changer, a workpiece clamping and releasing mechanism, and so on.

[0003] Among them, the workbench of the machine tool actuator includes a linear workbench, a rotary workbench, and a swing workbench. Among them, for the rotary workbench, the control system issues an instruction, and the servo system drives the machine tool according to the instruction of the control system, so that the tool and the part execute the movement specified by the numerical control code. At the same time, when the gear of the servo system rotates, the gear meshes with the gear of the worm, thereby driving the worm to rotate. The rotation of the worm causes the turbine on its surface to mesh and clamp with the rotating shaft at the bottom of the workbench. By rotating the worm back and forth, the rotating shaft at its bottom rotates back and forth to adjust its angle, so that the rotary platform can adjust its angle by 360 degrees, which is convenient for the tool and the part to process and polish the metal.

[0004] Deficiencies of an existing rotary workbench of a numerical control machine tool:

[0005] First, when the worm rotates back and forth to drive the rotating shaft at its bottom to rotate back and forth to adjust its angle, so that the rotary platform can adjust its angle by 360 degrees, and then the tool and the part process and polish the metal. For the machining burrs and sharp edges left after machining, grinding treatment is required. Due to the irregularity of the grinding part, the irregular splashing of iron filings will occur during the grinding process, seriously affecting the safety of the operator and the working environment hygiene.

[0006] Second, when the tool and the part process and polish the metal, due to the irregularity of the grinding part, the grinding time is increased. As a result, the temperature of its metal surface will gradually rise. Excessive temperature will damage the grinding tool, and at the same time drive the temperature of the work platform to gradually rise, which is likely to damage the device and reduce its service life.

[0016] The technical effects and advantages of the present invention:

[0017] 1. By providing eight heat dissipation devices, the eight heat dissipation devices are respectively located on both sides of the debris recovery device and directly below the top plate notch. Wind currents are generated by the eight heat dissipation devices. When the metal mold is being polished, the heat generated will be discharged along with the wind currents, reducing the temperature of the polished metal surface and the temperature on the work platform, protecting the safety of use of the polishing tool, and increasing its service life.

[0018] 2. The present invention is provided with a debris recovery device and a top electromagnetic device. The debris generated by the grinding of the metal mold will enter the bottom plate main body along with the heat and be shunted. By energizing the electromagnetic coil on the outer surface of the electromagnetic column and the bottom electromagnetic device, an electromagnetic field is generated respectively, so that the metal debris flying into the bottom plate main body can be adsorbed on the surface of the electromagnetic coil. At the same time, another part of the metal debris will fly towards the ventilation protection device due to too small magnetic force, and this part of the debris will be attracted by the magnetic field generated by the bottom electromagnetic device and then adsorbed on the surface of the bottom electromagnetic device, enabling the debris generated by metal grinding to be recycled, reducing the metal grinding cost, and at the same time preventing the metal debris from flying towards the heat dissipation device and causing damage to the heat dissipation device. The absorbed metal debris will gradually accumulate inside the heat dissipation frame. According to the length of the processing and grinding time, after the grinding is completed, the power supply to the bottom electromagnetic device and the electromagnetic coil is cut off, so that the magnetic field for deflecting and adsorbing the metal debris disappears, and then the metal debris adsorbed on the surface of the electromagnetic coil falls into the interior of the recovery device main body. At the same time, the metal debris adsorbed on the surface of the bottom electromagnetic device will loosen and spread inside the recovery device main body. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the forms of each structure described in the following implementation manners are only examples, and a workbench for a numerical control machine tool involved in the present invention is not limited to the structures described in the following implementation manners. All other implementation manners obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0030] Referring to Figure 1 , the present invention provides a workbench for a numerical control machine tool. A support bottom plate 2 is fixedly connected to the top of a support base 1. A base workbench device 3 is fixedly connected to the top of the support bottom plate 2. Workbench fixing devices 4 are fixedly connected to both sides of the base workbench device 3.

A main rotating workbench 7 is movably clamped to the other side of the top of the fixing bottom plate 5.

[0031] In this embodiment, it should be further noted that the number of the workbench fixing devices 4 is four. The whole device is installed on the numerically controlled machine tool through the four workbench fixing devices 4. By arbitrarily moving the positions of the secondary rotary workbench 6 and the main rotary workbench 7, it is convenient for the device to grind metal grinding tools with a wider range of sizes, increasing the applicability of the device.

[0032] Referring to Figure 2-3 , the support base plate 2 includes a base plate main body 201. A heat dissipation device 202 is fixedly connected to the bottom of the inner wall of the base plate main body 201. The heat dissipation device 202 includes a heat dissipation frame 2021. A heat dissipation fan 2022 is movably connected to the inner wall of the heat dissipation frame 2021. A fan blade device 2023 is fixedly connected to the outer wall of the heat dissipation fan 2022.

A top electromagnetic device 206 is fixedly connected to the bottom of the top plate 207;

[0033] In this embodiment, it should be further noted that the number of the heat dissipation devices 202 is eight, and the eight heat dissipation devices 202 are respectively located on both sides of the debris recovery device 203 and directly below the notch of the top plate 207. By generating air currents through the eight heat dissipation devices 202, the heat generated when the metal mold is ground will be discharged along with the air currents, reducing the temperature of the ground metal surface and the temperature on the work platform, protecting the safety of use of the grinding tool, increasing its service life. At the same time, by energizing the bottom electromagnetic device 2033 to generate an electromagnetic field, the metal debris flying towards the ventilation protection device 204 can be adsorbed on the surface of the bottom electromagnetic device 2033 for recycling, reducing the metal grinding cost.

[0034] Referring to Figure 5 , the top electromagnetic device 206 includes an adsorption housing 2061. An electromagnetic column 2062 is fixedly connected to the inner wall of the adsorption housing 2061. An electromagnetic coil 2063 is fixedly connected to the outer wall of the electromagnetic column 2062;

[0035] In this embodiment, it should be further explained that by energizing the electromagnetic coil 2063 on the outer surface of the electromagnetic column 2062 to generate an electromagnetic field, a part of the metal debris entering the bottom plate main body 201 from the second ventilation hole 303 is deflected and then adsorbed on the surface of the electromagnetic coil 2063, so that the debris generated by grinding the metal can be recycled, reducing the grinding cost of the metal mold and preventing the metal debris from flying towards the heat dissipation device 202 and damaging the heat dissipation device 202.

[0036] Refer to Figure 6-7 , the base workbench device 3 includes a base work main body 301. A debris recovery groove 302 is opened at the top of the base work main body 301. A second ventilation hole 303 is opened on the inner wall of the debris recovery groove 302. A base motor 304 is fixedly connected to the middle of the top of the base work main body 301. One end of the base motor 304 is fixedly connected to a base rotating shaft 305. A base sliding device 306 located on one side of the base motor 304 is fixedly connected to the middle of the top of the base work main body 301. One end of the base rotating shaft 305 is movably clamped with a base limiting plate 307. The top of the base sliding device 306 is movably connected to a sub-clamping block 604. A sub-rotary table bottom plate 603 is fixedly connected to the top of the sub-clamping block 604. A sub-rotary table main body 601 is fixedly connected to the sub-rotary table bottom plate 603. A sub-fixing device 602 is movably connected to the inner wall of the sub-rotary table main body 601. The outer wall of the fixed bottom plate 5 is movably clamped with a main rotary table bottom plate 702 located on one side of the sub-rotary table bottom plate 603. A workbench main body device 701 is fixedly connected to the top of the main rotary table bottom plate 702. A main clamping block 703 is fixedly connected to the bottom of the main rotary table bottom plate 702. A main movable block 704 located on one side of the main clamping block 703 is fixedly connected to the bottom of the main rotary table bottom plate 702;

[0037] In this embodiment, it should be further explained that by starting the base motor 304, the base rotating shaft 305 rotates, thereby adjusting the position of the main movable block 704 on the base rotating shaft 305, and then driving the workbench main body device 701 and the main rotary table bottom plate 702 to move on the base rotating shaft 305. Through the engagement of the two main clamping blocks 703 at the bottom of the main rotary table bottom plate 702 with the two base sliding devices 306, and simultaneously controlling the movement of the sub-clamping block 604 at the bottom of the sub-rotary table bottom plate 603 on the base sliding device 306, the sub-fixing device 602 and the main fixing device 7015 can more stably clamp the metal mold to be polished, and at the same time facilitate the sub-fixing device 602 and the main fixing device 7015 to clamp metal molds with a wider range of sizes, increasing the application range of the device.

[0038] Refer to Figure 8, the main rotary table 7 includes a table body device 701. A main rotary table bottom plate 702 is fixedly connected to the bottom of the table body device 701. A servo motor 705 is fixedly connected to the inner wall of the table body device 701. One end of the servo motor 705 is movably connected to a planetary reducer 706. One end of the planetary reducer 706 is movably connected to a rotating worm 707. A rotating thread 708 is fixedly connected to the outer wall of the rotating worm 707. The other end of the rotating worm 707 is movably connected to a rotating turbine 709. The other end of the rotating turbine 709 is movably connected to a worm fixing column 7010;

[0039] In this embodiment, it should be further explained that the servo motor 705, the planetary reducer 706, the rotating worm 707, the rotating thread 708, the rotating turbine 709, and the worm fixing column 7010 are combined together as a set of rotating devices. There are two sets of such rotating devices, and they are respectively located at the upper and lower ends on one side of the second main board 7014. By the simultaneous operation of the two sets of rotating devices, the main fixing device 7015 adjusts the angle, reducing the inertia caused by rotation on one side, reducing the friction between the rotating thread 708 and the main fixing column 7013, and increasing its service life.

[0040] Refer to Figure 9 , the table body device 701 includes a main table housing 7011. A first main board 7012 is fixedly connected to the inner wall of the main table housing 7011. A second main board 7014 is movably connected to the inner wall of the first main board 7012. One end of a main fixing column 7013 is fixedly connected to the main fixing column 7013. The other end of the second main board 7014 is fixedly connected to a main fixing device 7015;

[0041] In this embodiment, it should be further explained that when the rotating thread 708 rotates, the main fixing column 7013 will move along the direction of the thread gap of the rotating thread 708. Thus, the previous main fixing column 7013 exits from the front end, and the next main fixing column 7013 enters from the thread gap at the tail end of the rotating thread 708, thereby driving the second main board 7014 to rotate. Through the second main board 7014, the main fixing device 7015 and the metal mold clamped by the main fixing device 7015 are driven to rotate by adjusting the angle, which is convenient for the tool and the part to polish the periphery of the metal mold.

[0042] Working principle of the present invention: First, the user installs the device main body on the numerically controlled machine tool through the four workbench fixing devices 4, and then starts the base motor 304 to rotate the base rotating shaft 305, thereby adjusting the position of the main movable block 704 on the base rotating shaft 305, and then driving the workbench main body device 701 and the main turntable bottom plate 702 to move on the base rotating shaft 305. The two main clamping blocks 703 at the bottom of the main turntable bottom plate 702 are clamped with the two base sliding devices 306, and at the same time, the auxiliary clamping block 604 at the bottom of the auxiliary turntable bottom plate 603 is controlled to move on the base sliding device 306, so that the auxiliary fixing device 602 and the main fixing device 7015 can more stably clamp the metal mold to be polished. Then, the control system interprets and operates the data and acts on the machine tool. Then, the servo system drives the machine tool according to the instructions of the control system, so that the tool and the part execute the movement specified by the numerical control code. The servo motor 705 starts to work and is transmitted to the planetary reducer 706. The vibration transmitted by the servo motor 705 is decelerated by the planetary reducer 706, and then drives the rotating worm 707 to rotate. The rotating worm 707 drives the rotating thread 708 to rotate. At the same time, the thread gap of the rotating thread 708 is engaged and clamped with the main fixing column 7013. When the rotating thread 708 rotates, the main fixing column 7013 will move along the direction of the thread gap of the rotating thread 708. Then, the previous main fixing column 7013 exits from the front end, and the latter main fixing column 7013 enters from the thread gap at the end of the rotating thread 708, thereby driving the second main board 7014 to rotate. Through the second main board 7014, the main fixing device 7015 and the metal mold clamped by the main fixing device 7015 are driven to rotate by adjusting the angle, which is convenient for the tool and the part to polish the four sides of the metal mold. At the same time, the rotating turbine 709 connected to one end of the worm fixing column 7010 is movably connected to the other end of the rotating worm 707, so that the rotating worm 707 can rotate stably and uniformly. The upper and lower rotating worms 707 rotate at the same time, reducing the inertia caused by the rotation on one side, reducing the friction between the rotating thread 708 and the main fixing column 7013, and increasing its service life. During the polishing process, due to the irregularity of the polishing part, the irregular splashing of iron chips will occur during the polishing process. At this time, the fan blade device 2023 generates air flow as the cooling fan 2022 rotates. The air flow flows from top to bottom through the second ventilation hole 303, the first ventilation hole 205 and the slot holes at the bottom of the bottom plate main body 201, so that the debris generated by polishing enters the bottom plate main body 201 through the debris recovery groove 302 and the second ventilation hole 303 along with the air flow. At this time, the electromagnetic coil 2063 on the outer surface of the electromagnetic column 2062 will be energized to generate a magnetic field, causing a part of the metal debris entering the bottom plate main body 201 from the second ventilation hole 303 to deflect and adsorb on the surface of the electromagnetic coil 2063. At the same time, the bottom electromagnetic device 2033 in (3031) will also generate an electromagnetic field accordingly,Causes another part of the metal debris to adsorb on the surface of the bottom electromagnetic device 2033. The absorbed metal debris will gradually accumulate inside the heat dissipation frame 2021. According to the length of the processing and grinding time, after the grinding is completed, the bottom electromagnetic device 2033 and the electromagnetic coil 2063 are powered off, so that the magnetic field that causes the metal debris to deflect and adsorb disappears. As a result, the metal debris adsorbed on the surface of the electromagnetic coil 2063 falls into the inside of the recycling device main body 2031. At the same time, the metal debris adsorbed on the surface of the bottom electromagnetic device 2033 will loosen and spread inside the recycling device main body 2031. Pull the bottom electromagnetic device 2033 to make the recycling device main body 2031 come out of the bottom plate main body 201. Thus, the debris generated by grinding the metal can be recycled, reducing the grinding cost of the metal mold. At the same time, when the fan blade device 2023 rotates with the heat dissipation fan 2022 to generate air flow, the heat generated during the grinding of the metal mold will be discharged along with the air flow, reducing the temperature of the surface of the metal being ground and the temperature on the working platform, protecting the safety of using the grinding tool and increasing its service life.
