Description

Technical Field

[0001] The invention relates to the technical field of numerically controlled machine tools, and in particular to a five-axis numerically controlled machine tool for workpiece milling. Background Art

[0002] CNC machine tool is the abbreviation of digital control machine tool. It is an automated machine tool equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, and express them in coded numbers. They are input into the CNC device through information carriers. After calculation and processing, the CNC device sends various control signals to control the movement of the machine tool and automatically process parts according to the shape and size required by the drawing. During the milling process of CNC machine tools, the cutting position needs to be cooled by a water spray device. The five-axis linkage CNC machine tool is a machine tool used to process complex surfaces. The controlled lathe can process the complex rotating body shape, but the debris is easy to accumulate at the processing position when the workpiece is processed, so that the debris affects the processing accuracy when the processing continues. The accumulation of debris is easy to scratch the surface of the workpiece, reducing the integrity of the workpiece. The processing head is easy to generate heat, which causes the surface temperature of the workpiece and the processing head to rise, thus affecting the subsequent removal. The placement position of the workpiece is displaced during processing, which causes the processing position of the workpiece to shift and cause damage to the workpiece, increasing the difficulty of workpiece processing and reducing the efficiency of workpiece processing. The odor generated during workpiece processing causes it to drift, causing the air around the equipment to be polluted.

[0003] To sum up, when the workpiece is being processed, chips are easily accumulated at the processing position, which affects the processing accuracy when the processing continues. The accumulation of chips is easy to scratch the surface of the workpiece, and the processing head is easy to generate heat, which causes the surface temperature of the workpiece and the processing head to rise, thereby affecting the subsequent removal and increasing the difficulty of workpiece processing.

[0019] 1. The five-axis CNC machine tool used for workpiece milling is provided with a fixed plate, a milling machine, an electric push rod, and a connecting frame. The chassis can be sealed by a sealing plate provided thereon, so that dust accumulation inside the chassis is reduced when not in use, and the temperature of the milling machine and the workpiece is prevented from being too high to affect the use of the equipment, thereby avoiding the accumulation of debris on the clamping component to cause scratches on the workpiece surface, thereby increasing the accuracy of the milling machine processing, reducing the difficulty of workpiece processing, avoiding the influence of the circulation of coolant on cooling, ensuring the integrity of the workpiece processing, and allowing the debris and coolant generated by the workpiece to be collected through the clamping component.

[0020] 2.

The auxiliary block supports the auxiliary seat on the protective assembly, thereby increasing the bearing capacity of the auxiliary seat and preventing the auxiliary seat from tilting due to pressure, thereby ensuring that the auxiliary seat and the detector maintain the same horizontal plane on the protective assembly.

[0021] 3. The five-axis CNC machine tool used for workpiece milling can expand and contract on the liquid storage box according to the pulling force received through the elastic pipe rack, so that the mounting position of the metering cylinder can be adjusted by the adjusting rack, thereby increasing the working range of the metering cylinder. The metering cylinder is connected to the elastic pipe rack through the connecting end, so that the circulation of the coolant can be adjusted according to the processing needs, and the coolant sprayed by the spray head can be prevented from being interrupted. The spray head can spray liquid to different positions for cooling while driving the debris to move for collection.

[0022] 4. The five-axis CNC machine tool used for workpiece milling processing pushes the clamping plate to clamp the workpiece by extending the cylinder on the vertical plate, thereby improving the accuracy of subsequent processing, thereby increasing the clamping force of the workpiece and preventing the workpiece from loosening or tipping when clamped. The workpiece is placed on the placement plate to avoid the workpiece from being processed in place due to the large distance the components are moved, facilitating the circulation of debris and preventing the clamping plate from tilting when moving to affect the contact area of ​​the workpiece.

[0023] 5. The five-axis CNC machine tool used for workpiece milling collects chips and coolant through the recovery groove formed by the collecting shell through the receiving plate and the chassis, thereby avoiding the accumulation of chips and coolant at the clamping position to affect the processing of the workpiece, and facilitating the coolant to be statically treated in the collecting shell. The receiving plate is squeezed by the pressure of the workpiece to squeeze the buffer sleeve, thereby preventing the receiving plate from getting stuck during the lifting process, so that the side plate keeps the pressing plate fixed, thereby avoiding displacement of the pressing plate in the collecting shell.

[0024] 6. The five-axis CNC machine tool used for workpiece milling processing generates suction through the adsorption purifier to collect and purify the gas in the chassis through the protective frame, thereby reducing the odor inside the chassis, preventing the chassis from being damp for a long time and producing bacteria, and avoiding the debris from splashing everywhere in the chassis. The rotating disk rotates with the drive of the micro motor to prevent the gas circulation inside the circulation pipe from being affected, which is convenient for increasing the contact area of ​​the vibration plate and further improving the convenience of gas circulation inside the circulation pipe.

[0025] 7. The five-axis CNC machine tool used for workpiece milling processing, through the limiting plate inside the heat-conducting frame being rotated by the gas transmitted by the protective frame, is convenient for heat to circulate and dissipate on the heat-conducting frame, thereby accelerating the loss of heat inside the chassis, and the sliding block and the contact plate cooperate with each other to slide under the blowing of the gas, avoiding the accumulation of dust at the gas discharge position of the heat-conducting frame to affect the circulation of the gas, and facilitating the touch plate to stop moving when it rotates to contact the sliding block, thereby playing a role of limit reinforcement.

[0042] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms.

[0044] A chassis 1, wherein a sealing plate of the chassis 1 is rotatable to reveal an internal processing space, a clamping assembly 3 is connected to the bottom of the chassis 1, a protection assembly 4 is fixedly connected to the bottom of the inner cavity of the chassis 1, an auxiliary frame 9 is slidably connected to the top of the protection assembly 4, and a cooling assembly 2 is fixedly connected to a position of the chassis 1 away from the protection assembly 4;

[0045] A fixed disk 11 is driven by the electric push rod 8 to transport in the vertical direction. The outer surface of the fixed disk 11 is rotatably connected to a connecting plate 10. The bottom of the connecting plate 10 is fixedly connected to a connecting frame 7. The inner surface of the connecting frame 7 is rotatably connected to a reinforcing block 6. The bottom of the reinforcing block 6 is fixedly connected to a milling machine 5. The bottom of the fixed disk 11 is fixedly connected to the electric push rod 8. The top of the fixed disk 11 is slidably connected to the chassis 1. The chassis 1 can be sealed by a sealing plate provided thereon to reduce the accumulation of dust inside the chassis 1 when it is not in use. The cooling component 2 can be stretched along with the movement of the milling machine 5, thereby cooling down along with the processing of the milling machine 5 to prevent the temperature of the milling machine 5 and the workpiece from being too high and affecting the use of the equipment. The cooling liquid sprayed by the cooling component 2 can also wash away the debris while cooling down, thereby avoiding the accumulation of debris on the clamping component 3 and causing workpiece damage. When scratches appear on the surface of the workpiece, the fixed disk 11 is driven by the extension and retraction of the electric push rod 8 to lift up and down in the vertical direction, thereby adjusting the processing height of the subsequent milling machine 5. The motor on the fixed disk 11 drives the connecting frame 7 to rotate, so that the connecting frame 7 drives the reinforcing block 6 and the connecting frame 7 to rotate. The rotation of the connecting plate 10 on the fixed disk 11 can reinforce the fixed disk 11, avoiding the connection frame 7 from sliding down during rotation, thereby increasing the processing accuracy of the milling machine 5 and reducing the difficulty of workpiece processing. The milling machine 5 contacts the reinforcing block 6 and the cooling component 2, so that the coolant sprayed by the cooling component 2 is adjusted with the height of the milling machine 5, avoiding the circulation of the coolant affecting the cooling, making it difficult for the workpiece clamped by the clamping component 3 to move, ensuring the integrity of the workpiece processing, and allowing the debris and coolant generated by the workpiece to be collected by the clamping component 3;

The detector 94 contacts the protective component 4, so that the detector 94 slides under the thrust of the extension rod 93, so that the distance between the detector 94 and the auxiliary seat 92 is adjusted, and the extension rod 93 is extended to a length The moving range can be limited to prevent the detector 94 from falling off the protective component 4 due to excessive moving distance. The detector 94 can detect the temperature and dust inside the chassis 1 when working to prevent the components from rusting due to excessive humidity inside the chassis 1. The protective plate 96 is rotated on the reinforcement column 95, and the gas blown by the rotating protective plate 96 is close to the detector 94, which is convenient for the detector 94 to perform real-time detection and prevent the internal temperature of the chassis 1 from changing too much. The auxiliary block 91 supports the auxiliary seat 92 on the protective component 4, thereby increasing the bearing capacity of the auxiliary seat 92 and preventing the auxiliary seat 92 from tilting due to pressure, thereby ensuring that the auxiliary seat 92 and the detector 94 maintain the same horizontal plane on the protective component 4.

After the metering cylinder 27 rotates on the adjustment frame 24, it squeezes the elastic tube rack 22 through the connecting end 23, which is convenient for the liquid spray head 25 to flow to the non- Liquid is sprayed at different positions to cool down the temperature while driving the debris to move and collect. The outer surface of the metering cylinder 27 is rotatably connected to the adjusting frame 24, which expands and contracts on the liquid storage box 21 according to the tension received through the elastic pipe frame 22. The coolant is transported under the elastic force of the elastic pipe frame 22 itself. The adjusting frame 24 is distributed in a circular shape and cooperates with the elastic pipe frame 22, which is convenient for the adjusting frame 24 to adjust the installation position of the metering cylinder 27, so that the adjusting frame 24 can control the installation angle of the metering cylinder 27 while rotating, thereby increasing the working range of the metering cylinder 27, and the locking rod on the adjusting frame 24 can tighten the metering cylinder 27, so that the metering cylinder 27 is not easy to slip after installation, and the adjusting frame 24 is rotatably connected to the assembly frame 26 away from the metering cylinder 27.

The end of the plug rod 264 close to the assembly frame 261 is fixedly connected to the assembly block 266, and the outer surface of the assembly block 266 is fixedly connected to the support plate 265. The assembly block 266 is supported inside the assembly frame 261 by the support plate 265, and the plug rod 264 is installed by the assembly block 266 to keep the plug rod 264 level after installation, which avoids the plug rod 264 from being stuck when extending and retracting on the installation sleeve 262 and the assembly frame 261.

The clamping plate 34 is pushed to clamp the workpiece by extending the cylinder on the vertical plate 33. When the clamping plate 34 clamps the workpiece, it can push the workpiece so that the workpiece and the milling machine 5 are placed relative to each other, thereby improving the accuracy of subsequent processing. In addition, a magnet 35 is arranged on the clamping plate 34, so that the magnet 35 can adsorb the iron workpiece, thereby increasing the clamping force of the workpiece, preventing the workpiece from loosening or tipping over when clamping, and further improving the quality of workpiece processing.

The receiving plate 373 is subjected to the pressure of the workpiece placed on it to squeeze the buffer sleeve 376, so that the buffer sleeve 376 descends. At the same time, the side support plate 377 supports the receiving plate 373 on the abutment sleeve 374, and keeps the receiving plate 373 vertically lifted and lowered to prevent the receiving plate 373 from getting stuck during the lifting process. The side support plate 377 can increase the supporting force, and the side connecting plates 378 are distributed in a circular shape on the pressing plate 375, so that the side connecting plates 378 keep the pressing plate 375 fixed, thereby avoiding displacement of the pressing plate 375 in the collecting shell 371.

[0054] The side support plate 377 is slidably connected to the receiving plate 373 at a position away from the abutting sleeve 374 , and the bottom of the side support plate 377 is fixedly connected to the collecting shell 371 .

[0055] The protection component 4 includes a protection frame 41, the inner surface of which is fixedly connected with an adsorption purifier 42, and a circulation pipe 43 is connected to the adsorption purifier 42 at a position away from the protection frame 41. The adsorption purifier 42 generates suction to collect and purify the gas in the chassis 1 through the protection frame 41, and the purified gas is transported to the circulation pipe 43 for circulation, so that the gas is discharged after multiple cycles, thereby reducing the odor inside the chassis 1 and preventing the chassis 1 from being damp for a long time and producing bacteria. The protection frame 41 can be protected in the chassis 1, and the protection frame 41 is used to block debris to avoid the debris from splashing everywhere in the chassis 1. The circulation pipe 43 is rotatably connected with a vibration plate 46 at a position away from the adsorption purifier 42. A rotating disk 44 is fixedly connected to the vibration plate 46 at a position away from the circulation pipe 43. The side of the rotating disk 44 away from the vibration plate 46 is rotatably connected to the protective frame 41. The vibration plate 46 is slidably connected to the circulation pipe 43 at a position close to the circulation pipe 43. The rotating disk 44 rotates driven by the micro motor, and the vibration plate 46 strikes the circulation pipe 43 as the rotating disk 44 rotates, preventing the internal gas circulation of the circulation pipe 43 from being affected. When the vibration plate 46 rotates, the resistance block 47 is thrown out, which is convenient for increasing the contact area of ​​the vibration plate 46 and facilitating the vibration plate 46 to repeatedly strike the circulation pipe 43, further improving the convenience of internal gas circulation of the circulation pipe 43 and avoiding blockage caused by dust accumulation in the circulation pipe 43. The outer surface of the protective frame 41 is connected to the external display frame 45.

[0056] Among them, the external display frame 45 includes a middle solid column 455, the outer surface of the middle solid column 455 is fixedly connected with a touch plate 456, the touch plate 456 is rotatably connected to the heat-conducting frame 452 at a position away from the middle solid column 455, the two ends of the middle solid column 455 are rotatably connected with the heat-conducting frame 452, and the heat-conducting frame 452 is rotatably connected with a limiting plate 451 at a position away from the middle solid column 455. The gas transmitted by the protective frame 41 inside the heat-conducting frame 452 rotates through the limiting plate 451, so that the limiting plate 451 limits the rate at which the regulated gas enters the heat-conducting frame 452, and the heat-conducting frame 452 guides the heat while circulating the gas, so that the heat is circulated and dissipated on the heat-conducting frame 452, thereby accelerating the loss of heat inside the chassis 1, and the limiting plate 451 is attenuated when the gas is weakened. When the heat conducting frame 452 is in the open position, it is automatically reset to seal the inlet of the heat conducting frame 452, thereby separating the inside of the heat conducting frame 452. The heat conducting frame 452 is slidably connected to a sliding block 453 at a position close to the limiting plate 451, and the sliding block 453 is fixedly connected to a contact plate 454 on a side away from the limiting plate 451. The sliding block 453 and the contact plate 454 cooperate with each other and slide under the blowing of gas, so that the sliding block 453 can clean the groove on the heat conducting frame 452 when it moves, thereby avoiding dust accumulation at the gas discharge position of the heat conducting frame 452 to affect the gas circulation. The middle solid column 455 is driven by the gas in the heat conducting frame 452 to rotate the touch plate 456, so that the touch plate 456 stops moving when it rotates to contact the sliding block 453, thereby playing a role of limiting reinforcement.

[0057] Example 2, please refer to Figure 1-Figure 15 On the basis of Example 1, the present invention provides a technical solution: a method for using a five-axis CNC machine tool for milling a workpiece, step 1: rotating the sealing plate on the chassis 1 to expose the internal space of the chassis 1, placing the workpiece on the placement plate 31, using the circular part of the support column 36 to support the placement plate 31, the cylinder on the vertical plate 33 extends to push the clamping plate 34 to clamp the workpiece, the guide rod 32 moves on the vertical plate 33 with the movement of the clamping plate 34, when the workpiece material is iron, the magnet 35 adheres to the clamping plate 34;

[0058] Step 2: After the workpiece is clamped, the electric push rod 8 extends to drive the fixed plate 11 to descend, and the top of the fixed plate 11 drives the connecting frame 7 to rotate, so that the connecting frame 7 drives the connecting plate 10 to rotate on the fixed plate 11, and at the same time, the connecting frame 7 drives the milling machine 5 to rotate through the reinforcing block 6, and the workpiece is processed when it contacts the workpiece. The detector 94 and the auxiliary seat 92 slide on the protective frame 41, so that the detector 94 detects the temperature and dust inside the chassis 1 in real time, and the protective plate 96 is shaken to rotate on the reinforcement column 95 to drive the airflow close to the detector 94;

[0059] Step 3: The mounting sleeve 262 is mounted on the milling machine 5 via the plug-in rod 264, so that it moves with the milling machine 5. As the milling machine 5 moves, the external plate 263 rotates on the mounting sleeve 262, and the plug-in rod 264 drives the assembly frame 261 to move together. The adjustment frame 24 on the assembly frame 261 rotates to adjust the angle of the metering cylinder 27, and the locking column on the adjustment frame 24 tightens the metering cylinder 27.

[0060] Step 4: The coolant in the liquid storage box 21 is transported to the connecting end 23 through the elastic pipe rack 22, and the connecting end 23 transports the coolant to the liquid spray head 25 through the quantitative cylinder 27 to spray the coolant onto the workpiece. The sprayed coolant gradually flows into the recovery tank formed by the receiving plate 373 and the chassis 1, so that the water flows into the collection shell 371 for collection, and the blocking ring 372 intercepts the impurities driven by the coolant;

[0061] Step 5: The receiving plate 373 is pressed down, so that the receiving plate 373 applies pressure to the pressing plate 375 through the buffer sleeve 376, and the side support plate 377 on the abutting sleeve 374 is rotated by the pressure of the receiving plate 373, and the side connecting plate 378 is fixed on the pressing plate 375 in a circular shape, and the protective frame 41 is used to collect the gas during the processing inside the chassis 1;

[0062] Step six: As the gas enters the adsorption purifier 42 through the protective frame 41, the air in the adsorption purifier 42 is purified and then transported to the circulation pipe 43 for circulation. At the same time, the rotating disk 44 is driven by the micro motor to rotate, and the rotating disk 44 drives the vibration plate 46 to knock on the circulation pipe 43 when it contacts the circulation pipe 43. The resistance block 47 slides with the rotation of the vibration plate 46 and contacts the circulation pipe 43 with the rotation. The gas inside the protective frame 41 is processed and transported to the heat conduction frame 452. As the gas circulates, it pushes the limiting plate 451 to rotate. The circulation of gas inside the heat conduction frame 452 drives the sliding block 453 to move, and the touch plate 456 drives the middle solid column 455 to rotate inside the heat conduction frame 452.
