Description

Technical Field

[0001] The invention belongs to the technical field of high-pressure spindle cooling for numerically controlled machine tools, in particular to a high-pressure spindle internal cooling system for numerically controlled machine tools applied to deep hole processing. Background Art

[0002] A CNC machine tool is a digitally controlled machine tool, which is an automated machine tool equipped with a program control system that can logically process programs specified by control codes or other symbolic instructions, decode them, represent them with coded numbers, and input them into the CNC device through an information carrier.

[0003] In the process of deep hole processing by CNC machine tools in the prior art, the operator will first write the corresponding processing program in the CNC programming software according to the processing requirements. After the programming is completed, the program is transmitted to the control system of the CNC machine tool. Then, the machine tool performs a series of preparations, including the installation and adjustment of the tool, the clamping and positioning of the workpiece, and the setting of cutting parameters. For deep hole processing, special deep hole drills or gun drills are usually selected. These tools have special geometric shapes and cooling and lubrication systems to ensure effective chip removal and reduce cutting temperature during the processing. After everything is ready, the CNC machine tool starts to run automatically according to the preset program. During the processing, the tool cuts the workpiece at an extremely high speed and precise feed rate. At the same time, the cooling system of the machine tool continues to work to provide sufficient coolant for the cutting area to take away the cutting heat and lubricate the contact surface between the tool and the workpiece. When the processing is completed, the machine tool automatically stops running.

[0004] However, in the existing deep hole processing process, since the circumferential surface of the deep hole drill rod is generally provided with special shapes, such as spiral grooves, etc., to facilitate chip removal and the circulation of coolant, when the drill rod completes the drilling operation, some rolled metal debris is often stuck on its surface. These debris are tightly attached to the drill rod due to the special shape of the drill rod surface, and the high temperature and pressure generated during the processing process, and are difficult to fall off by themselves. These residual metal debris will not only affect the subsequent use of the drill rod, such as causing problems such as increased tool wear and reduced processing accuracy, but may also pose a potential threat to the safety of operators.

[0005] To this end, the present invention provides a high-pressure spindle internal cooling system for a CNC machine tool used for deep hole processing. Summary of the invention

DETAILED DESCRIPTION

[0033] 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.

[0034] Embodiment 1: Figures 1 to 6 As shown, a high-pressure spindle internal cooling system for a CNC machine tool used for deep hole processing described in an embodiment of the present invention comprises a machine body 1, a triangular chuck 11 is arranged on the upper surface of the machine body 1, and the triangular chuck 11 is used to fix a steel column; a frame 3 is fixedly connected to one side of the machine body 1, a servo motor 12 is fixedly connected to the frame 3, and a drill rod 13 is fixedly connected to the output end of the servo motor 12; a slide 2 is slidably connected to the upper surface of the machine body 1, and a grinding assembly is arranged on the slide 2, and the grinding assembly comprises a rotating ring 23 rotatably arranged above the machine body 1, and a plurality of grinding blocks 26 are fixedly connected to the inner wall of the rotating ring 23, and the plurality of grinding blocks 26 are distributed in a circular array, and the plurality of grinding blocks 26 are used to grind the circumferential surface of the steel column; a cleaning assembly is arranged inside the frame 3, and the cleaning assembly comprises a connecting ring 33 rotatably arranged on one side of the frame 3, and the connecting ring 33 is used to clean the surface of the drill rod 13.

[0035] Specifically, in the existing deep hole processing process, since the circumferential surface of the deep hole drill rod 13 is generally provided with a special shape, such as a spiral groove, etc., to facilitate chip removal and the circulation of coolant, when the drill rod 13 completes the drilling operation, some rolled metal debris is often stuck on its surface. These debris are interlocked with the special shape of the surface of the drill rod 13, and the high temperature and pressure generated during the processing make them tightly attached to the drill rod 13 and difficult to fall off by themselves. These residual metal debris will not only affect the subsequent use of the drill rod 13, such as causing problems such as increased tool wear and reduced processing accuracy, but may also pose a potential threat to the safety of operators;

[0036] Therefore, the present invention solves this problem by setting a corresponding structure. First, the steel column is fixed on the triangular chuck 11, and the servo motor 12 is started. Its output end drives the drill rod 13 to rotate. The position of the grinding component is adjusted by the slide 2 so that the grinding block 26 on the inner wall of the rotating ring 23 contacts the circumferential surface of the steel column. As the steel column rotates, the grinding operation is realized. After long-term use, debris will adhere to the surface of the drill rod 13, affecting the subsequent drilling accuracy. At this time, the cleaning component is used to rotate the connecting ring 33 on one side of the frame 3 to make it fit the surface of the drill rod 13. During the rotation of the drill rod 13, the connecting ring 33 scrapes off the debris to ensure that the drill rod 13 is clean. At the same time, the slide 2 can flexibly adjust the grinding The relative position of the components and the steel column can adapt to different processing requirements. The grinding blocks 26 are distributed in a circular array and can evenly grind the circumferential surface of the steel column. This device has multiple functions, integrating drilling, grinding and cleaning functions of the drill rod 13, reducing the steps of replacing equipment during processing and improving work efficiency. The triangular chuck 11 can firmly fix the steel column to ensure processing accuracy. The design of the grinding component makes the circumferential surface of the steel column evenly grind, improving the processing quality. The cleaning component can effectively remove debris on the surface of the drill rod 13, extend the service life of the drill rod 13, and reduce maintenance costs. The slidability of the slide 2 increases the flexibility of the device and can meet the processing requirements of steel columns of different specifications.

[0037] The problem of rolled metal debris stuck on the surface of the drill rod 13 is solved.

[0039] Specifically, after the steel column is fixed to the triangular chuck 11 on one side of the machine body 1, the steel column fixed to the triangular chuck 11 is pushed by driving the hydraulic cylinder built into the machine body 1, and the steel column gradually approaches the drill rod 13, and then the servo motor 12 is started, and the start of the servo motor 12 drives the drill rod 13 to rotate, so as to perform deep hole drilling on the steel column;

[0040] The device adopts a design in which a hydraulic cylinder pushes the steel column close to the drill rod 13, which has significant beneficial effects. The hydraulic cylinder pushing process is smooth and controllable, and can accurately adjust the distance between the steel column and the drill rod 13 to ensure that the starting position of deep hole drilling is accurate and effectively avoid processing errors caused by position deviation. The servo motor 12 drives the drill rod 13 to rotate, with strong power and stable speed, which can ensure high efficiency and accuracy of deep hole drilling and improve processing quality. The overall design reduces manual intervention, reduces labor intensity, improves production efficiency, and enhances the safety and stability of the processing process.

The nozzles 25 will move with the movement of the slide 2, so that uninterrupted cooling work can be performed while drilling. The sanding assembly also includes a first motor 21 fixedly connected to the top of the slide 2. The output end of the first motor 21 is transmission-connected to a transmission belt 22, and the transmission belt 22 is transmission-connected to a rotating ring 23, so that the sanding block 26 can be driven to perform sanding work.

[0042] Specifically, during drilling, a plurality of nozzles 25 fixedly connected to one side of the slide 2 move with the slide 2, and continuously spray coolant to the drilling site to achieve uninterrupted cooling. At the same time, the first motor 21 fixedly connected to the top of the slide 2 is started, and its output end drives the rotating ring 23 to rotate through the transmission belt 22, and the grinding block 26 on the inner wall of the rotating ring 23 rotates accordingly to grind the circumferential surface of the steel column. During the whole process, the cooling of the nozzle 25 and the grinding of the grinding block 26 are carried out synchronously without interfering with each other. The moving cooling of the nozzle 25 effectively reduces the drilling temperature, reduces thermal deformation, improves the drilling accuracy, and extends the life of the drill rod 13; the first motor 21 drives the grinding block 26 to grind to ensure the processing quality of the circumferential surface of the steel column. The two work together to improve the processing efficiency and quality and reduce production costs.

[0044] Specifically, after the second motor 31 is started, it can drive the driving belt 32 to transmit, and the transmission belt 22 of the driving belt 32 drives the connecting ring 33 to rotate. The connecting ring 33 is supported by two support frames 34 to rotate. After the connecting ring 33 rotates, it drives several cleaning plates 315 on its inner wall to clean and remove the work, and at the same time, it can drive the maintenance component to perform maintenance work; the second motor 31 drives the driving belt 32 to transmit, and then drives the connecting ring 33 to rotate stably under the support of the two support frames 34. The structure is stable and reliable. The several cleaning plates 315 on the inner wall of the connecting ring 33 rotate accordingly, which can efficiently clean and remove the debris on the surface of the drill rod 13, ensure the cleanliness of the drill rod 13, extend its service life, and reduce maintenance costs. At the same time, it can also drive the maintenance component to work, maintain the drill rod 13 and other components, and improve the overall performance of the equipment. This design realizes the linkage of cleaning and maintenance functions, has a high degree of automation, reduces manual operation, improves work efficiency, and ensures long-term and stable operation of the equipment.

[0045] Embodiment 2: Figures 1 to 6 As shown, compared with Example 1, another embodiment of the present invention is: the maintenance component includes a connecting belt 35 that is transmission-connected to the output end of the second motor 31, one end of the connecting belt 35 is transmission-connected to a reciprocating screw 36, the reciprocating screw 36 is rotatably arranged on the inner wall of the frame 3, the circumferential surface of the reciprocating screw 36 is slidingly connected to a belt block 37, one side of the belt block 37 is fixedly connected to a piston column 38, the inner wall of the frame 3 is fixedly connected to a piston cylinder 39, the piston column 38 performs piston motion in the piston cylinder 39, one side of the piston cylinder 39 is connected to a connecting pipe 310, the circumferential surface of the connecting pipe 310 is fixedly connected to a connecting plate 311, the lower surface of the connecting plate 311 is fixedly connected to a positioning ring 312, a plurality of rotating columns 313 are rotatably connected in the positioning ring 312, and the rotating columns 313 are used for applying grease.

[0046] Specifically, the second motor 31 rotates while driving the connecting belt 35 to rotate, and then the reciprocating screw 36 is driven to rotate through the connecting belt 35. The rotation of the reciprocating screw 36 drives the belt block 37 on its circumferential surface, and the belt block 37 slides along the reciprocating screw 36, thereby pushing the piston rod to perform piston movement in the piston cylinder 39, squeezing the grease in the frame 3 into the connecting pipe 310, and then flowing into the connecting plate 311, infiltrating the rotating column 313, so as to perform maintenance and lubrication work on the drill rod 13 after the drilling is completed;

[0047] The second motor 31 drives the connecting belt 35 to drive the reciprocating screw 36 to rotate, so that the belt block 37 slides along the reciprocating screw 36 to push the piston rod to perform piston movement, and accurately controls the extrusion amount and speed of the grease. The grease flows to the connecting plate 311 through the connecting pipe 310 and infiltrates the rotating column 313, so as to perform comprehensive maintenance and lubrication on the drill rod 13 after drilling. This process has a high degree of automation and does not require frequent manual operation, thereby reducing labor intensity. At the same time, timely and effective lubrication can reduce the wear of the drill rod 13, extend its service life, ensure stable operation of the equipment, reduce maintenance costs, and improve overall production efficiency and economic benefits.

[0049] Working principle: first fix the steel column on the triangular chuck 11, start the servo motor 12, and its output end drives the drill rod 13 to rotate. The position of the grinding component is adjusted through the slide 2, so that the grinding block 26 on the inner wall of the rotating ring 23 contacts the circumferential surface of the steel column. The grinding operation is realized as the steel column rotates. After long-term use, debris will adhere to the surface of the drill rod 13, affecting the subsequent drilling accuracy. At this time, the cleaning component is used to rotate the connecting ring 33 on one side of the frame 3 to make it fit the surface of the drill rod 13. During the rotation of the drill rod 13, the connecting ring 33 scrapes off the debris to ensure that the drill rod 13 is clean. At the same time, the slide 2 can flexibly adjust the relative position of the grinding component and the steel column. Position, adapted to different processing requirements, the grinding blocks 26 are distributed in a circular array, and can evenly grind the circumferential surface of the steel column. This device has multiple functions, integrating drilling, grinding and cleaning functions of the drill rod 13, reducing the steps of replacing equipment during processing and improving work efficiency. The triangular chuck 11 can firmly fix the steel column to ensure processing accuracy. The design of the grinding component makes the circumferential surface of the steel column evenly grind, improving the processing quality. The cleaning component can effectively remove debris on the surface of the drill rod 13, extend the service life of the drill rod 13, and reduce maintenance costs. The slidability of the slide 2 increases the flexibility of the device and can meet the processing requirements of steel columns of different specifications;

[0050] Specifically, during drilling, a plurality of nozzles 25 fixed to one side of the slide 2 move with the slide 2, and continuously spray coolant to the drilling site to achieve uninterrupted cooling. At the same time, the first motor 21 fixed to the top of the slide 2 is started, and its output end drives the rotating ring 23 to rotate through the transmission belt 22, and the grinding block 26 on the inner wall of the rotating ring 23 rotates accordingly to perform grinding on the circumferential surface of the steel column. During the whole process, the cooling of the nozzle 25 and the grinding of the grinding block 26 are performed synchronously without interfering with each other. The moving cooling of the nozzle 25 effectively reduces the drilling temperature, reduces thermal deformation, improves the drilling accuracy, and prolongs the life of the drill rod 13; the first motor 21 drives the grinding block 26 to grind, ensuring the processing quality of the circumferential surface of the steel column. The two work together to improve the processing efficiency and quality and reduce the production cost.

[0051] In addition, the cleaning component is specific, after the second motor 31 is started, it can drive the driving belt 32 to transmit, the transmission belt 22 of the driving belt 32 drives the connecting ring 33 to rotate, and the connecting ring 33 is supported by the two support frames 34 to rotate.
