Description

Technical Field

[0001] This invention belongs to the field of workpiece processing technology, specifically a precision milling and grinding integrated machine tool. Background Technology

[0002] In the field of precision machining, milling is a common process in workpiece processing. The grinding process after milling is a key follow-up step to ensure the surface accuracy of the workpiece groove and eliminate milling burrs and flash. It directly affects the assembly performance and service life of the workpiece. After the workpiece is milled by a special milling machine, it is then transferred to an independent grinding machine for subsequent grinding operations.

[0003] First, when the workpiece is transferred to the grinding equipment after milling, it needs to be re-clamped and fixed. This second clamping process not only consumes a lot of manual operation time, but also easily causes machining errors due to clamping and positioning deviations, affecting the positional accuracy and dimensional consistency of the groove. Second, after re-fixing the workpiece, the grinding head of the grinding equipment needs to be recalibrated, and the feed value of the grinding head needs to be reconstructed according to the groove parameters. This calibration and parameter setting process is cumbersome, further extending the processing cycle and reducing production efficiency.

[0004] Crucially, during the rough grinding stage, to ensure grinding effectiveness, the rotation direction of the grinding wheel and the milling cutter must be properly matched (e.g., reverse counter-clamping to improve the efficiency of material removal). This requires operators to additionally record the milling cutter's rotation direction parameters after the milling process and transmit these parameters to the grinding process, then adjust the grinding wheel's rotation direction on the grinding equipment accordingly. This process not only increases the number of steps but may also lead to improper grinding wheel rotation settings due to errors in parameter recording or transmission, thus affecting rough grinding efficiency and even causing quality problems such as scratches or residual texture on the groove surface.

[0005] Therefore, the present invention provides a precision milling and grinding integrated machine tool. Summary of the Invention

The guide bar is slidably connected to the guide ring. The axial end of the milling shaft passes through the driven wheel and is rotatably connected to the movable end of the control cylinder.

[0009] Preferably, an adapter ring is fixedly installed on the bottom surface of the mounting frame, and the adapter ring has a cavity inside, through which the grinding shaft passes. A suction tube is fixedly installed on the bottom surface of the adapter ring. Multiple suction tubes are provided and are evenly distributed in a ring along the axis of the adapter ring. A control pump is fixedly installed on the outer wall of the mounting frame, and the input end of the control pump is connected to the inner cavity of the adapter ring.

[0010] Preferably, a storage cylinder is fixedly installed on the outer wall of the mounting frame, and a closed end cap is detachably installed on the bottom of the storage cylinder; A filter cartridge is detachably installed on the inner wall of the storage cylinder. The bottom of the storage cylinder is connected to the inner cavity of the adapter ring via a conduit. The input end of the control pump is fixedly connected to the upper end of the storage cylinder.

[0011] Preferably, a support frame is fixedly installed on the outer wall of the storage cylinder, a conical plug is elastically installed on one side of the support frame, and an exhaust hole adapted to the conical plug is opened on the inner wall of the storage cylinder. A guide cylinder is fixedly installed on the outer wall of the support frame, a control plug is slidably installed on the inner wall of the guide cylinder, a connecting rod is fixedly installed on the outer wall of the control plug, and the other end of the connecting rod passes through the guide cylinder and is fixedly connected to the outer wall of the conical plug.

[0012] Preferably, a storage ring is fixedly installed on the outer wall of the grinding shaft, and a connecting ring is rotatably installed on the outer wall of the storage ring. The outer wall of the connecting ring is fixedly connected to the inner wall of the mounting frame, and the outer wall of the connecting ring communicates with the inner cavity of the guide cylinder through a conduit. A control cylinder is fixedly installed on the inner wall of the storage ring, and an adjusting plug is elastically installed on the inner wall of the control cylinder. The outer wall of the adjusting plug slides against the inner wall of the control cylinder.

[0013] Preferably, an exhaust pipe connected to the output end of the control pump is fixedly installed on the outer wall of the mounting frame, a sliding plug is elastically installed on the inner wall of the exhaust pipe, and a rigid pipe is fixedly installed on the bottom surface of the sliding plug.

[0015] The beneficial effects of this invention are as follows: 1. This invention achieves integrated milling and grinding operations by setting up a collaborative structure of control motor, one-way bearing, and mounting bracket and frame. It fundamentally solves the core pain point of traditional separate machining. The workpiece only needs to be clamped on the stage once to complete milling and grinding, completely avoiding the positioning deviation caused by secondary clamping, ensuring the positional accuracy and dimensional consistency of the groove. The forward and reverse rotation of the control motor can directly drive the milling spindle to rotate in the reverse direction and the grinding spindle to rotate in the forward direction through the one-way bearing. There is no need to manually record the milling cutter direction and adjust the grinding tool direction, avoiding machining defects caused by parameter transmission errors. At the same time, the parallel axes of the milling spindle and the grinding spindle can share the same stroke control program, eliminating the need for recalibration and parameter construction steps, greatly shortening the processing cycle, and improving rough grinding efficiency and groove surface machining accuracy.

[0016] 2. This invention achieves a cleaner and more efficient milling process by incorporating a control pump, an adapter ring, and a flexible hose and perforated block structure within the exhaust hood. During milling, the control pump creates a uniform negative pressure through the adapter ring, which, combined with the annularly distributed suction pipes, promptly removes dust, preventing it from affecting processing accuracy and equipment lifespan. After milling, the control pump drives the exhaust hood to descend, and the flexible hose causes the perforated block to vibrate, allowing for thorough cleaning of extremely fine metal shavings within the groove, preventing wear on the grinding wheel and scratches on the groove. This design seamlessly integrates cleaning and milling processes, eliminating the need for additional cleaning equipment while ensuring the cutting performance and lifespan of the grinding wheel, further enhancing the comprehensive advantages of integrated processing.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 11 As shown, the precision milling and grinding integrated machine tool of the present invention includes a load-bearing part, a control part, a mounting part, and a milling and grinding mechanism.

[0022] The support unit includes a platform 1, a gantry frame 2, and a lifting frame 3. The gantry frame 2 is fixedly installed on the upper end face of the platform 1, and the lifting frame 3 is slidably installed on the side wall of the gantry frame 2. The gantry frame 2 is equipped with a screw rail for controlling the lifting frame 3 to slide in the horizontal direction.

[0023] The mounting section includes a mounting bracket 10 and a mounting frame 7. The mounting bracket 10 is slidably mounted on the side wall of the lifting frame 3. A vertical screw rail is provided inside the lifting frame 3 to control the vertical lifting of the mounting bracket 10. The mounting frame 7 is fixedly mounted on the outer wall of the mounting bracket 10. The position of the mounting frame 7 can be adjusted by sliding the mounting bracket 10 and the lifting frame 3.

[0024] The control unit includes a control cylinder 9 and a control motor 8, which are fixedly installed on the upper end of the mounting frame 7. The control cylinder 9 is a common hydraulic cylinder.

[0025] The milling and grinding mechanism includes a milling cutter mounting head 4, a grinding head mounting head 14, a grinding shaft 11, and a milling shaft 19. The grinding shaft 11 is rotatably mounted on the inner wall of the mounting frame 7, and the grinding head mounting head 14 is fixedly mounted on the bottom of the grinding shaft 11. The grinding head mounting head 14 is used to fix the grinding tool, and rotating the grinding shaft 11 controls the rotation of the grinding head to facilitate milling and grinding of the workpiece.

[0026] The milling spindle 19 is movably disposed inside the mounting frame 7. The milling cutter mounting head 4 is fixedly mounted on the bottom of the milling spindle 19. The milling cutter mounting head 4 is used to mount the milling cutter. Rotating the milling spindle 19 controls the rotation of the milling cutter, thereby milling grooves on the workpiece fixed on the platform 1.

[0027] The axes of the milling shaft 19 and the grinding shaft 11 are parallel to each other. The rotation of the milling shaft 19 and the grinding shaft 11 is controlled by the control motor 8, and the lifting and lowering of the milling shaft 19 is controlled by the control cylinder 9.

[0028] During operation, the workpiece is first fixed on the platform 1. The horizontal screw slide rail inside the gantry 2 controls the horizontal sliding of the lifting frame 3, which in turn drives the mounting frame 10 to rise and fall. This adjusts the mounting frame 7 to be directly above the workpiece processing area. Then, the control cylinder 9 drives the milling spindle 19 to descend to the working position. The control motor 8 drives the milling spindle 19 to rotate and completes the milling groove processing through the milling cutter on the milling cutter mounting head 4. After the milling groove is completed, the control cylinder 9 drives the milling spindle 19 to rise and reset. Then, the mounting frame 10 drives the mounting frame 7 to descend, so that the grinding tool on the grinding head mounting head 14 reaches the milling groove position. The control motor 8 drives the grinding spindle 11 to rotate to complete the grinding operation. Finally, the lifting frame 3 and the mounting frame 10 are reset, and the processed workpiece is taken out.

[0029] This achieves integrated milling and grinding operations. The workpiece only needs to be clamped once on the platform 1, without needing to be transferred to other equipment for re-fixing after milling. This completely avoids the errors caused by secondary positioning. At the same time, the axes of the milling shaft 19 and the grinding shaft 11 are parallel to each other, and their heights can be adjusted to the same state. They can share a set of control stroke programs, which greatly simplifies the operation steps and program writing process, effectively shortens the overall processing time of the workpiece, and improves processing efficiency and the processing accuracy of the milled groove surface.

[0030] The output shaft of the control motor 8 is fixedly equipped with a drive wheel 12. The drive wheel 12 is connected to the grinding shaft 11 through a one-way bearing, so that the control motor 8 drives the drive wheel 12 to rotate. When the control motor 8 controls the drive shaft to rotate in the forward direction, the grinding shaft 11 rotates synchronously. When the control motor 8 controls the drive wheel 12 to rotate in the reverse direction, the grinding shaft 11 remains stationary.

[0031] A support ring 21 is fixedly installed on the inner wall of the mounting frame 7. A driven wheel 17 is rotatably installed on the upper end of the support ring 21, and the support ring 21 provides support for the driven wheel 17.

[0032] Driven wheel 17 is connected to driving wheel 12 via a transmission component. In this embodiment, a common belt is used as the transmission component. The driving wheel 12 and driven wheel 17 are connected by the belt, thereby controlling the rotation of driven wheel 17 when the driving wheel 12 rotates.

[0033] A guide ring 23 is rotatably mounted on the bottom surface of the driven wheel 17 via a one-way bearing. When the driven wheel 17 rotates in the forward direction, the guide ring 23 remains stationary. When the driven wheel 17 rotates in the reverse direction, the guide ring 23 rotates synchronously in the reverse direction.

[0034] A guide bar 20 is fixedly installed on the outer wall of the milling shaft 19. The guide bar 20 is slidably connected to the guide collar 23. The outer wall of the guide bar 20 is slidably attached to the inner wall of the guide collar 23 to facilitate the sliding of the milling shaft 19. At the same time, when the guide collar 23 rotates, it drives the milling shaft 19 to rotate.

[0035] The axial end of the milling shaft 19 passes through the driven wheel 17 and is rotatably connected to the movable end of the control cylinder 9. The milling shaft 19 is raised and lowered by sliding the movable end of the control cylinder 9.

[0036] After the workpiece is fixed on the platform 1, the control cylinder 9 is activated to drive its movable end, along with the milling shaft 19, to descend to the working position. At this time, the control motor 8 rotates in the opposite direction and drives the drive wheel 12 on the output shaft to rotate in the opposite direction synchronously. The drive wheel 12 is connected to the grinding shaft 11 through a one-way bearing. In this reverse rotation state, the grinding shaft 11 remains stationary. At the same time, the drive wheel 12 drives the driven wheel 17 at the upper end of the support collar 21 to rotate in the opposite direction through belt transmission. The guide collar 23 connected to the bottom surface of the driven wheel 17 through the one-way bearing rotates in the opposite direction synchronously with it, thereby driving the milling shaft 19 to rotate. The milling groove is completed by the milling cutter on the milling cutter mounting head 4.

[0037] After milling is completed, the control cylinder 9 drives the milling shaft 19 to rise and reset. Then, the mounting frame 7 is lowered by the mounting bracket 10, so that the grinding tool on the grinding head mounting head 14 reaches the milling position. At this time, the control motor 8 rotates forward and drives the drive wheel 12 to rotate forward synchronously. The drive wheel 12 drives the grinding shaft 11 to rotate synchronously through the one-way bearing. At the same time, the drive wheel 12 drives the driven wheel 17 to rotate forward through the belt. In this forward rotation state, the guide collar 23 connected to the driven wheel 17 remains stationary, the milling shaft 19 does not rotate, and the grinding shaft 11 drives the grinding tool to rotate to complete the grinding operation. Finally, the lifting frame 3 and the mounting bracket 10 are reset, and the processed workpiece is taken out.

[0038] The milling cutter rotates in the opposite direction with the milling spindle 19, and the grinding wheel rotates in the forward direction with the grinding spindle 11. During rough grinding, the grinding direction of the reverse rotation forms a counterbalance with the milling pattern of the milling cutter, which can more efficiently remove burrs and machining allowance from the inner wall of the milling groove. At the same time, it can offset some of the forces generated by milling and grinding, reduce the vibration of the workpiece on the table 1, and ensure machining accuracy. If another grinding machine is used to complete the rough grinding process separately, the rotation direction of the milling cutter needs to be recorded separately, and the grinding wheel direction needs to be adjusted accordingly to achieve reverse grinding. This not only increases the risk of errors in operation steps and manual recording, but also prolongs the overall processing time. This machine tool relies on the integrated milling and grinding structure and directly drives the milling spindle 19 and the grinding spindle 11 to rotate in the opposite direction by controlling the forward and reverse rotation of the motor 8. No additional recording and adjustment are required, which greatly simplifies the process and improves the processing efficiency.

[0039] In a preferred embodiment of the present invention, a transition ring 41 is fixedly installed on the bottom surface of the mounting frame 7. The transition ring 41 has a cavity inside. The grinding shaft 11 passes through the transition ring 41. A gap is left between the radial outer wall of the grinding shaft 11 and the inner ring of the transition ring 41 to prevent friction between the grinding shaft 11 and the transition ring 41 when the grinding shaft 11 rotates.

[0040] A suction tube 13 is fixedly installed on the bottom surface of the adapter ring 41, connecting the adapter ring 41 to the external negative pressure chamber, thereby allowing suction through the suction tube 13. Multiple suction tubes 13 are provided, and the multiple suction tubes 13 are evenly distributed in a ring along the axis of the adapter ring 41, thereby creating a uniform suction area near the mold.

[0041] A control pump 5 is fixedly installed on the outer wall of the mounting frame 7. The input end of the control pump 5 is connected to the inner cavity of the adapter ring 41. When the control pump 5 is working, a negative pressure is generated inside the adapter ring 41, thereby drawing through the suction pipe 13.

[0042] During the milling process of grinding the workpiece, the control pump 5 is activated to form a stable negative pressure inside the adapter ring 41, which drives multiple suction pipes 13 that are evenly distributed in a ring along the axis of the adapter ring 41 to simultaneously draw in dust. This creates a uniform negative pressure suction area near the grinding wheel on the grinding head mounting head 14, which promptly removes the dust generated during milling and grinding, preventing dust from drifting and adhering to the workpiece surface or equipment parts, thus affecting the processing accuracy and equipment lifespan. Furthermore, thanks to the integrated milling and grinding design, the workpiece only needs to be clamped on the platform 1 once to complete the milling and grinding operations. The dust collection structure is arranged nearby around the grinding wheel, eliminating the need for readjustment or additional dust collection devices during process changes. This further simplifies the operation process, saves processing auxiliary time, and ensures the high efficiency and cleanliness of the integrated milling and grinding operation.

[0043] A storage cylinder 6 is fixedly installed on the outer wall of the mounting frame 7. A closed end cap 27 is detachably installed on the bottom of the storage cylinder 6. The closed end cap 27 is connected to the storage cylinder 6 by a threaded connection.

[0044] A filter cartridge 42 is detachably installed on the inner wall of the storage cylinder 6. The bottom of the storage cylinder 6 is connected to the inner cavity of the adapter ring 41 through a conduit. The input end of the control pump 5 is fixedly connected to the upper end of the storage cylinder 6. The filter cartridge 42 is located between the input end of the control pump 5 and the connection position of the adapter ring 41. When the control pump 5 is working, the dust drawn in is intercepted inside the storage cylinder 6 by the filter cartridge 42. The dust collected inside can be removed by removing the sealing cover 27.

[0045] In a preferred embodiment of the present invention, an exhaust pipe 15 connected to the output end of the control pump 5 is fixedly installed on the outer wall of the mounting frame 7. A three-way valve is provided at the connection position between the control pump 5 and the exhaust pipe 15. Adjusting the three-way valve adjusts the exhaust direction of the control pump 5. When the control pump 5 is working, the air pressure in the inner cavity of the exhaust pipe 15 increases. A sliding plug 33 is elastically installed on the inner wall of the exhaust pipe 15. A rigid tube 34 is fixedly installed on the bottom surface of the sliding plug 33. Thus, when the control pump 5 is working, the sliding plug 33 and the rigid tube 34 are controlled to slide downward.

[0046] An exhaust hood 40 is fixedly installed at the bottom of the rigid tube 34. An installation cover 32 for installing brush bristles is fixedly installed on the outer wall of the exhaust hood 40. The brush bristles are closed in a ring along the inner wall of the installation cover 32.

[0047] After the milling is completed, adjust the position of the mounting frame 7 until the exhaust hood 40 is above the milled groove. At this time, start the control pump 5, causing the exhaust hood 40 to descend until the brush bristles are inside the milled groove. At the same time, the exhaust hood 40 exhausts air to remove metal chips from the groove, thereby preventing metal chips from getting stuck between the grinding wheel on the grinding head mounting head 14 and the inner wall of the milled groove. This prevents surface defects such as scratches and pulls caused by the extrusion of metal chips during grinding, ensuring the flatness of the milled groove surface after rough grinding. It also reduces the clogging and wear of the grinding wheel abrasive grains by metal chips, maintains the rough grinding cutting performance of the grinding wheel, extends the service life of the grinding wheel, and ensures the stability and uniformity of the removal of the remaining material during rough grinding. Finally, it can eliminate the interference of metal chips on the grinding wheel grinding trajectory, avoid the problem of local under-grinding or over-grinding caused by metal chips raising the grinding wheel, and improve the rough grinding accuracy. Relying on the structural advantages of the integrated milling and grinding, this cleaning step can be completed directly on the machine without transferring the workpiece to other cleaning equipment, eliminating the separate cleaning process and significantly shortening the overall processing time.

[0048] A support frame 30 is fixedly installed on the outer wall of the storage cylinder 6. A conical plug 31 is elastically installed on one side of the support frame 30. A spring is fixedly connected to the inner wall of the support frame 30. The other end of the spring is fixed to the outer wall of the conical plug 31. An exhaust hole adapted to the conical plug 31 is opened on the inner wall of the storage cylinder 6. The conical plug 31 controls the opening and closing of the inner cavity of the storage cylinder 6.

[0049] When cleaning the milling groove with a blower, the exhaust port is controlled to be open, thereby reducing the resistance of the pump 5 to maintain the exhaust force of the exhaust hood 40 and maintain the quality of cleaning the milling groove. When the dust generated during cleaning and grinding is sucked up (at this time, the exhaust from the output end of the pump 5 is directly discharged through the three-way valve), the conical plug 31 is controlled to close the exhaust port. At this time, the inside of the storage cylinder 6 is kept closed, thereby maintaining the suction force.

[0050] A guide cylinder 26 is fixedly installed on the outer wall of the support frame 30, and a control plug 28 is slidably installed on the inner wall of the guide cylinder 26. The outer wall of the control plug 28 is sealed and fitted with the inner wall of the guide cylinder 26.

[0051] A connecting rod 29 is fixedly installed on the outer wall of the control plug 28. The other end of the connecting rod 29 passes through the guide cylinder 26 and is fixedly connected to the outer wall of the conical plug 31. Sliding the control plug 28 causes the control plug 28 to slide.

[0052] A storage ring 22 is fixedly installed on the outer wall of the grinding shaft 11. The storage ring 22 stores liquid (purified water is selected in this embodiment). A connecting ring 18 is rotatably installed on the outer wall of the storage ring 22. The connecting ring 18 is connected to the storage ring 22 through a sealed bearing.

[0053] The outer wall of the connecting ring 18 is fixedly connected to the inner wall of the mounting frame 7. The outer wall of the connecting ring 18 is connected to the inner cavity of the guide cylinder 26 through a conduit, thereby realizing the connection between the storage ring 22 and the inner cavity of the guide cylinder 26.

[0054] A control cylinder 25 is fixedly installed on the inner wall of the storage ring 22. An adjusting plug 24 is elastically installed on the inner wall of the control cylinder 25. The outer wall of the adjusting plug 24 slides against the inner wall of the control cylinder 25. A counterweight is provided inside the adjusting plug 24.

[0055] When the grinding shaft 11 rotates, it drives the storage ring 22 to rotate. At this time, the centrifugal force is used to control the sliding of the adjusting plug 24, which causes the hydraulic pressure inside the storage ring 22 and the guide cylinder 26 to rise, driving the control plug 28 and the conical plug 31 to slide until the exhaust hole is closed. When the grinding shaft 11 is stationary, the storage ring 22 remains stationary. At this time, the adjusting plug 24 is reset until the conical plug 31 closes the exhaust hole again. Thus, when the grinding shaft 11 rotates, the exhaust hole on the outer wall of the storage cylinder 6 is kept closed, and dust is sucked in. When the grinding shaft 11 is stationary, the exhaust hole on the outer wall of the storage cylinder 6 is opened, and metal chips in the milling groove are cleaned.

[0056] A flexible hose 36 is fixedly installed on the inner wall of the exhaust hood 40, and a perforated block 37 is fixedly installed on the other end of the flexible hose 36. When exhausting, the perforated block 37 connected to the flexible hose 36 on the inner wall of the exhaust hood 40 shakes under the action of the exhaust airflow, which in turn drives the brush bristles on the mounting cover 32 to shake synchronously. This design can significantly improve the removal effect of metal chips in the milling groove. On the one hand, the shaking brush bristles can more thoroughly clean the dead corners and gaps of the inner wall of the milling groove, and completely remove the extremely fine metal chips that cannot be cleaned by simple airflow and stationary brush bristles, thus avoiding metal chip residue.

[0057] A connecting frame 16 is fixedly installed on the outer wall of the exhaust pipe 15. A combing plate 38 is rotatably installed on the outer wall of the connecting frame 16 via a torsion spring. The combing plate 38 has an "L" shaped structure.

[0058] A control block 39 is fixedly installed on the inner wall of the combing plate 38, and an attraction block 35 for attracting the control block 39 is fixedly installed on the outer wall of the rigid tube 34. The attraction block 35 is a magnet, and the control block 39 is an iron block.

[0059] After cleaning the milling groove, the exhaust direction of the control pump 5 is adjusted by the three-way valve. At this time, the sliding plug 33 is reset by the elastic force. During the reset process, the control block 39 and the suction block 35 gradually approach each other. At this time, the combing plate 38 deflects to prevent the combing plate 38 from obstructing the reset of the exhaust hood 40. As the control block 39 and the suction block 35 gradually move away from each other, the combing plate 38 resets and inserts into the bristles. As the exhaust hood 40 continues to slide, the bristles are combed by the combing plate 38 for the next use.
