Description

Technical Field

[0001] The invention relates to the technical field of machine tool equipment, and in particular to a CNC machine tool with an anti-jamming servo tailstock. Background Art

[0002] In the field of modern mechanical processing, CNC machine tools play an extremely important role and are widely used in the manufacture of various precision parts. Among them, the tailstock, as one of the key components of the machine tool, plays an indispensable role in ensuring processing accuracy and stability.

[0003] Traditional machine tool tailstocks are often simple in structural design and are mostly operated manually or hydraulically. The manual tailstock operation is inefficient and cannot meet the needs of high-precision and high-efficiency processing. At the same time, the CNC machine tool tailstock lacks an effective automatic lubrication system during long-term use. It is difficult to ensure the timeliness and uniformity of lubrication by relying solely on manual regular lubrication, which increases the friction between the moving parts of the tailstock and makes it easy to get stuck. During the processing, impurities such as chips and coolant residues enter the gap between the moving parts of the tailstock, which will further aggravate the jam and affect the normal movement of the tailstock, bringing certain adverse effects to people's use process. In order to solve the shortcomings of the prior art, we propose a CNC machine tool with an anti-jamming servo tailstock. Summary of the invention

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The CNC machine tool with an anti-jamming servo tailstock can drive the lead screw to rotate by means of a first servo motor. When the first servo motor is started, the lead screw can be driven to rotate. Due to the threaded matching relationship between the lead screw and the moving block, the moving block will generate lateral movement under the action of the thread during the rotation of the lead screw, and the lateral movement of the moving block can further drive the tailstock saddle connected thereto and the base and the rear center installed at the upper end of the tailstock saddle to move laterally together. In this way, the rear center can be used to implement stable support operations for slender shaft parts of different lengths, effectively reduce the processing errors caused by the deformation of the workpiece itself, and greatly improve the processing accuracy. At the same time, the support guide rod can play a precise guiding role during the movement of the tailstock saddle, effectively ensuring the stability of the tailstock saddle and the base and the rear center installed at the upper end thereof during the movement, thereby ensuring the stability and reliability of the entire processing process.

[0021] 2. The CNC machine tool with an anti-jamming servo tailstock is provided with a high-pressure air pump. When the high-pressure air pump is started, the outside air is sucked in through the air inlet, and the dust and impurities in the air can be effectively filtered out by the filter in the air inlet. After being compressed, the inhaled air is transported to the air pipe through the air hose and the connector, and then transmitted to the hollow connecting block through multiple connecting pipes, and finally sprayed out by the blowing nozzle. In this way, during the lateral movement of the tailstock saddle, the surfaces of the lead screw and the two supporting guide rods can be cleaned, which effectively avoids the jamming of the moving block and the tailstock saddle during movement caused by dust or processing debris on the surfaces of the lead screw and the two supporting guide rods, effectively guarantees the smoothness and stability of the movement of the tailstock saddle, and improves the overall operation reliability and processing accuracy of the machine tool.

[0022] 3. The CNC machine tool with an anti-jamming servo tailstock can smoothly perform the oil filling operation on the oil storage tank with the help of the set oil inlet pipe, thereby realizing the storage function of the lubricating oil. Since the contact block and the surface of the support guide rod are in contact with each other, when the tailstock slide saddle moves laterally, the friction force generated between the contact block and the support guide rod will prompt the contact block to drive the rotating shaft to rotate. During this rotation process, the contact block can bring out the lubricating oil stored in the oil storage tank and apply it on the surface of the support guide rod to achieve the oiling effect, so as to reduce friction resistance and prevent the occurrence of jamming. At the same time, by setting a protective ring, dust and impurities adsorbed on the surface of the support guide rod can be effectively prevented from entering the circular groove when the tailstock slide saddle moves, thereby ensuring the cleanliness and stability of the lubrication system. In addition, by means of the set wiper, the lubricating oil can be effectively limited to prevent it from flowing out of the circular groove, so that it can be effectively limited to the circular groove area between the two wipers, thereby ensuring the reasonable distribution and efficient use of the lubricating oil, further improving the reliability and stability of the machine tool operation, and extending the service life of related components.

[0023] 4. The CNC machine tool with an anti-jamming servo tailstock can drive the first rotating rod and the first gear to start rotating by setting a second servo motor. When the second servo motor is started, the second gear can be driven to rotate synchronously through the transmission belt under the meshing action, thereby prompting the second rotating rod to rotate synchronously. When the first rotating rod and the second rotating rod rotate synchronously, the third gear will be driven to rotate, and the gear ring meshing with the third gear will rotate accordingly. When the gear ring rotates, it can drive the fixed ring and the connecting ring to rotate together. In this way, the wiping block on the inner surface of the connecting ring can evenly apply the lubricating oil pre-applied on the surface of one side of the support guide rod to the entire surface of the support guide rod, thereby ensuring that the support guide rod is fully and evenly lubricated, effectively reducing frictional resistance, and preventing the occurrence of jamming. In this process, the ball can ensure the stability of the connecting ring during rotation, making the lubricating oil application process more stable and reliable, further improving the smoothness and stability of the machine tool operation.

[0024] 5. The CNC machine tool with an anti-jamming servo tailstock can efficiently carry out disassembly and assembly operations on the mounting seat on the upper end of the mounting table with the help of the first bolt, and can conveniently complete the disassembly and assembly of the base on the upper end of the mounting seat with the second bolt. A clamping block is provided, because one side of which is inclined, when the top base drives the clamping block to contact the inner cavity of the base, the clamping block will shrink into the rectangular groove opened by the top base, thereby driving the limit plate to move in the rectangular groove. During the movement of the limit plate, the distance between the connecting plate and the moving plate will be compressed, and then the spring sleeved on the outer surface of the telescopic rod will be squeezed. After the top base completely enters the interior of the base, the spring will push the moving plate outward, pushing the clamping block to pop out from the through groove opened on the surface of the base, and the connection operation of the top base is completed.

[0025] 6. For the CNC machine tool with an anti-jamming servo tailstock, when it is necessary to disassemble the top base, it is only necessary to apply inward pressure to the clamping block to overcome the elastic force of the spring and press the two clamping blocks into the corresponding two rectangular grooves respectively. At this time, the clamping blocks are separated from the through grooves on the surface of the base, and the lock between the top base and the base is released, so that the top base can be directly pulled out from the base to complete the disassembly operation of the top base.

DETAILED DESCRIPTION

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0038] Embodiment 1, as Figure 1-Figure 4 As shown, a CNC machine tool with an anti-jamming servo tailstock, a fixed plate 5 is welded inside the bed 2, a first servo motor 6 is detachably connected to one side of the bed 2, an output end of the first servo motor 6 passes through the bed 2 and is detachably connected to a lead screw 7 through a coupling, two supporting guide rods 8 are symmetrically welded between the fixed plate 5 and the inner surface of one side of the bed 2, a moving block 9 is threadedly connected to the outer surface of the lead screw 7, a tailstock saddle 10 is welded to the upper end of the moving block 9, and the tailstock saddle 10 is slidably connected to the outer surfaces of the two supporting guide rods 8.

[0039] When the first servo motor 6 is started, the screw rod 7 can be driven to rotate. Due to the threaded matching relationship between the screw rod 7 and the moving block 9, during the rotation of the screw rod 7, the moving block 9 will produce lateral movement under the action of the thread, and the lateral movement of the moving block 9 can further drive the tailstock saddle 10 connected thereto and the base 14 and the rear center 18 installed on the upper end of the tailstock saddle 10 to move laterally. In this way, the rear center 18 can be used to implement stable support operations for slender shaft parts of different lengths. At the same time, the support guide rod 8 is set to play a precise guiding role during the movement of the tailstock saddle 10, which effectively ensures the stability of the tailstock saddle 10 and the base 14 and the rear center 18 installed on its upper end during the movement.

[0040] Embodiment 2, as Figure 1-Figure 4 As shown, a CNC machine tool with an anti-jamming servo tailstock, a high-pressure air pump 27 is detachably connected to the upper end of the bed 2, an air inlet 28 is detachably connected to the upper end of the high-pressure air pump 27, a filter is installed in the air inlet 28, an air hose 29 is detachably connected to one side of the high-pressure air pump 27, and the other end of the air hose 29 is detachably connected to the air pipe 31 through a connector 30, two wire pipe clamps 32 are symmetrically welded on one side of the mounting platform 11, the wire pipe clamps 32 are sleeved on the outer surface of the air pipe 31, a hollow connecting block 34 is connected to the inside of the air pipe 31 through a connecting pipe 33, and an air blowing nozzle 35 is welded to the lower end of the hollow connecting block 34.

[0041] When the high-pressure air pump 27 is started, outside air is sucked in through the air inlet 28, and under the action of the filter screen in the air inlet 28, dust and impurities in the air can be effectively filtered out. After being compressed, the inhaled air is transported to the air pipe 31 through the air hose 29 and the connector 30, and then transmitted to the hollow connecting block 34 through multiple connecting pipes 33, and finally sprayed out by the blowing nozzle 35. In this way, during the lateral movement of the tailstock saddle 10, the surfaces of the screw rod 7 and the two supporting guide rods 8 can be cleaned, effectively avoiding the situation where the moving block 9 and the tailstock saddle 10 are stuck during movement due to dust or processing debris on the surfaces of the screw rod 7 and the two supporting guide rods 8.

[0042] Embodiment three, as Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 , Fig. 9 As shown, a CNC machine tool with an anti-jamming servo tailstock, an oil inlet pipe 37 is welded to one side of the tailstock saddle 10, the oil inlet pipe 37 is connected to the oil storage tank 36 opened inside the tailstock saddle 10, a bearing 39 is detachably embedded in the bottom of a circular slot 38 opened in the tailstock saddle 10, a rotating shaft 40 is rotatably connected to the bearing 39, a contact block 41 is welded to the outer surface of the rotating shaft 40, the contact block 41 is in contact with the surface of the support guide rod 8, two circular grooves 42 are opened inside the tailstock saddle 10, a plurality of fixed cylinders 43 are respectively welded to the openings at both ends of the circular grooves 42, a protective ring 44 is detachably connected in the fixed cylinder 43, and two wipers 57 are symmetrically installed in the circular groove 42.

[0043] With the help of the oil inlet pipe 37, the oil storage tank 36 can be smoothly filled with oil, thereby realizing the storage function of the lubricating oil. Since the contact block 41 and the surface of the support guide rod 8 are in contact with each other, when the tailstock saddle 10 moves laterally, the friction force generated between the contact block 41 and the support guide rod 8 will prompt the contact block 41 to drive the rotating shaft 40 to rotate. During this rotation process, the contact block 41 can bring out the lubricating oil stored in the oil storage tank 36 and apply it to the surface of the support guide rod 8 to achieve the oiling effect. At the same time, by setting the protective ring 44, the dust and impurities adsorbed on the surface of the support guide rod 8 can be effectively prevented from entering the circular groove 42 when the tailstock saddle 10 moves. In addition, with the wiper 57, the lubricating oil can be effectively limited to prevent it from flowing out of the circular groove 42, so that it can be effectively confined to the circular groove 42 area between the two wipers 57.

[0044] Embodiment 4, as Figure 1 , Figure 2 , Figure 4 , Figure 7 , Figure 8 , Fig.10 As shown, a CNC machine tool with an anti-jamming servo tailstock, the second servo motor 45 is detachably connected to one side of the tailstock saddle 10, the output end of the second servo motor 45 passes through the tailstock saddle 10 and is detachably connected to the first rotating rod 46 through a coupling, the first gear 47 is welded to the outer surface of the first rotating rod 46, the transmission toothed belt 48 is meshed with the outer surface of the first gear 47, the inner surface of the other end of the transmission toothed belt 48 is meshed with the second gear 49, the second gear 49 is welded to the outer surface of the second rotating rod 50, two third gears 51 are respectively welded to the outer surfaces of the first rotating rod 46 and the second rotating rod 50, the ring gear 52 is meshed with the third gear 51, the fixing ring 53 is welded to the inner surface of the ring gear 52, the connecting ring 54 is welded to the inner surface of the fixing ring 53, a plurality of wiping blocks 55 are detachably connected to the inner surface of the connecting ring 54 in an annular shape, and a plurality of groups of balls 56 are rollingly connected between the outer surface of the connecting ring 54 and the inner surface of the circular groove 42.

[0045] When the second servo motor 45 is started, the first rotating rod 46 and the first gear 47 can be driven to start rotating. Under the meshing action, the second gear 49 can be driven to rotate synchronously through the transmission belt 48, thereby prompting the second rotating rod 50 to rotate synchronously. When the first rotating rod 46 and the second rotating rod 50 rotate synchronously, the third gear 51 will be driven to rotate, and the ring gear 52 meshing with the third gear 51 will rotate accordingly. When the ring gear 52 rotates, it can drive the fixed ring 53 and the connecting ring 54 to rotate together. In this way, the wiping block 55 on the inner surface of the connecting ring 54 can evenly apply the lubricating oil pre-applied to the surface of one side of the support guide rod 8 to the entire surface of the support guide rod 8, thereby ensuring that the support guide rod 8 is fully and evenly lubricated. In this process, the ball 56 can ensure the stability of the connecting ring 54 during rotation.

[0046] Embodiment 5, as Figure 1-Figure 6 As shown, a CNC machine tool with an anti-jamming servo tailstock, the mounting seat 12 is detachably connected to the upper end of the mounting platform 11 by a first bolt 13, the base 14 is detachably connected to the upper end of the mounting seat 12 by a second bolt 15, the top base 17 is detachably connected to the base 14, the rear top 18 is detachably connected to one side of the top base 17, the limit frame 20 is welded to the surface of the top base 17 at the opening of the rectangular groove 19, the connecting plate 21 is welded in the rectangular groove 19, the telescopic rod 22 is detachably connected between the connecting plate 21 and the movable plate 24, the spring 23 is movably sleeved on the outer surface of the telescopic rod 22, the limit plate 25 is movably connected to the rectangular groove 19, the clamping block 26 is welded to one end of the limit plate 25, one side of the clamping block 26 is inclined, and the clamping block 26 matches the through groove 16 opened on the surface of the base 14.

[0047] With the help of the first bolt 13, the mounting seat 12 at the upper end of the mounting platform 11 can be efficiently disassembled and assembled, and the second bolt 15 can be used to conveniently complete the disassembly and assembly of the base 14 at the upper end of the mounting seat 12. A clamping block 26 is provided, and because one side of it is inclined, when the top base 17 drives the clamping block 26 to contact the inner cavity of the base 14, the clamping block 26 will be retracted into the rectangular groove 19 opened by the top base 17, thereby driving the limiting plate 25 to move in the rectangular groove 19. During the movement of the limiting plate 25, the distance between the connecting plate 21 and the moving plate 24 will be compressed, thereby squeezing the spring 23 sleeved on the outer surface of the telescopic rod 22, and waiting for After the top base 17 completely enters the base 14, the spring 23 will push the movable plate 24 outward, pushing the clamping block 26 to pop out of the through groove 16 opened on the surface of the base 14, and the connection operation of the top base 17 is completed. When it is necessary to disassemble the top base 17, it is only necessary to apply inward pressure to the clamping block 26 to press the two clamping blocks 26 into the corresponding two rectangular grooves 19 respectively. At this time, the clamping block 26 is separated from the through groove 16 on the surface of the base 14, and the lock between the top base 17 and the base 14 is released, so that the top base 17 can be directly pulled out from the base 14 to complete the disassembly operation of the top base 17.

[0048] It should be noted that the present invention is a CNC machine tool with an anti-jamming servo tailstock. When in use, the workpiece is clamped and fixed at one end by the chuck 4, and then the first servo motor 6 is driven to drive the screw rod 7 to rotate. At this time, the moving block 9 will drive the tailstock saddle 10 at its upper end to move laterally as the screw rod 7 rotates, and then drive the base 14 and the rear center 18 installed on the upper end of the tailstock saddle 10 to move laterally until the rear center 18 moves to provide stable support for the other end of the workpiece. When the tailstock saddle 10 moves, the two supporting guide rods 8 can effectively guide it to avoid swinging and offset during movement.

[0049] When the first servo motor 6 is started to drive the tailstock slide 10 to move, the high-pressure air pump 27 is started synchronously. At this time, the outside air is sucked in and compressed through the air inlet 28, and then the compressed air is delivered to the air pipe 31 through the air hose 29 and the connector 30. Then, the compressed air flows along the air pipe 31 and is introduced into the corresponding hollow connecting block 34 through the connecting pipe 33. Finally, a plurality of air blowing nozzles 35 are used to spray out dust and processing debris on the surface of the screw rod 7 and the two supporting guide rods 8, thereby effectively avoiding the jamming of the moving block 9 and the tailstock slide 10 when moving due to the presence of dust and impurities.

[0050] The storage of lubricating oil can be completed by injecting the lubricating oil into the oil storage tank 36 through the oil inlet pipe 37. When the tailstock saddle 10 moves laterally during the operation of the machine tool, the contact block 41 in contact with the surface of the support guide rod 8 will cause the contact block 41 and the rotating shaft 40 to rotate due to the friction generated therebetween. When the contact block 41 rotates, the lubricating oil stored in the oil storage tank 36 is brought out and smeared on the surface of one side of the support guide rod 8 to achieve oiling and lubrication operation. When the tailstock saddle 10 moves, the protective ring 44 can effectively block the air nozzle 35 from cleaning the dust and impurities on the surface of the support guide rod 8 and blowing the dust and impurities into the circular groove 42. Under the action of the wiper 57, the lubricating oil in the circular groove 42 can be prevented from flowing out, and the lubricating oil is confined to the circular groove 42 between the two wipers 57, ensuring that the lubricating oil is reasonably distributed and continuously exerts its lubrication effect.

[0051] During the machining operation, the second servo motor 45 is started to drive the first rotating rod 46 to rotate. At this time, the first gear 47 welded on the outer surface of the first rotating rod 46 will also rotate. At the same time, under the transmission action of the transmission toothed belt 48, the second gear 49 and the second rotating rod 50 can be driven to rotate synchronously. When the first rotating rod 46 and the second rotating rod 50 rotate synchronously, the two third gears 51 can be driven to rotate. Since the third gear 51 is engaged with the ring gear 52, the ring gear 52 can be driven to rotate when the third gear 51 rotates. At the same time, the fixed ring 53 and the connecting ring 54 welded in the ring gear 52 can be driven to rotate. When the connecting ring 54 rotates, the wiping block 55 arranged on its inner surface can evenly apply the lubricating oil applied to one side of the support guide rod 8 to the entire surface of the support guide rod 8, so that all parts of the support guide rod 8 can be lubricated, effectively ensuring the comprehensiveness and uniformity of the lubrication.

[0052] When installing the top base 17 and the rear top 18, align the top base 17 with the inner cavity direction of the base 14 and push it into the base 14. After the clamping block 26 contacts the inner cavity wall of the base 14, since one side of the clamping block 26 is an inclined surface, when the top base 17 is pushed further, the clamping block 26 will be retracted into the rectangular groove 19 opened in the top base 17. At this time, the clamping block 26 will be pushed to move in the rectangular groove 19, and the moving direction of the limit plate 25 is toward the direction of the compression spring 23. At this time, the limit plate 25 will gradually squeeze the distance between the connecting plate 21 and the moving plate 24, and the top base 1 After the top base 14 is completely inserted into the base 14, the elastic force of the spring 23 pushes the movable plate 24 to move outward, and then drives the limit plate 25 and the clamping block 26 to move outward. At this time, the clamping block 26 pops out from the through groove 16 provided on the surface of the base 14 and is clamped in the through groove 16. In this way, the installation of the top base 17 and the base 14 can be completed. When the top base 17 needs to be disassembled, it is only necessary to press the clamping block 26 to retract it into the rectangular groove 19. At this time, the clamping block 26 will be separated from the through groove 16 provided on the surface of the base 14, and then the top base 17 can be pulled out from the base 14 to complete the disassembly.
