Description

Technical Field

[0001] This invention relates to the field of composite machining center technology, specifically to a vertical turning-milling composite machining center and its usage method. Background Technology

[0002] Vertical turning-milling machining centers are core equipment in the field of precision machining. They are mainly used for turning and milling composite machining of shafts, discs, and various irregularly shaped precision workpieces. The workpiece clamping firmness, the stability of the machining process, and the level of on-site safety protection directly determine the workpiece machining accuracy, surface finish quality, and mass production safety. Currently, most conventional vertical turning-milling machining centers on the market are equipped with traditional mechanical chucks, pressure plate clamps, and other basic structures for workpiece clamping. These can only achieve a single mechanical clamping function, and their overall structure has obvious technical shortcomings, making it difficult to adapt to the current industry's high-precision, high-efficiency, and high-safety machining requirements.

[0003] During processing, workpiece loosening is a core hidden danger leading to precision deviations, equipment damage, and even safety accidents. Currently, the industry lacks dedicated workpiece loosening monitoring beacons and related auxiliary structures. Equipment relies solely on operators' visual inspection to determine the workpiece's condition, making it impossible to predict clamping failures in advance, resulting in significant delays. Once a workpiece becomes loose or shifts, the equipment lacks any delay-limiting or chip-flying prevention structures, easily leading to workpiece misalignment and scrapping, high-speed chip flying, and even the risk of workpiece falling off, directly threatening the safety of the equipment and operators. Furthermore, conventional equipment has a low overall level of automation. If additional monitoring components are added later, manual clamping, disassembly, and adjustment are required, necessitating frequent machine stops during batch processing. This cumbersome and time-consuming process significantly reduces processing efficiency. Moreover, external monitoring devices require separate power supply lines and sensor modules, leading to high failure rates and inconvenient maintenance in harsh workshop conditions with cutting fluid and metal dust, resulting in poor practicality and an inability to achieve stable and reliable passive early warning and long-term monitoring.

[0004] In view of this, we propose a vertical turning and milling machining center and its usage method. Summary of the Invention

[0005] The purpose of this invention is to provide a vertical milling and turning machining center and its usage method, to solve the problems mentioned in the background art, such as the inability to monitor workpiece loosening in real time and the prominent safety hazards. To achieve the above objective, this invention provides the following technical solution: a vertical milling and turning machining center, including a worktable, multiple annular strong magnets, several beacons, a rotary support, inner wall strong magnets, and a signal generator.

[0006] The ring-shaped strong magnets are locked and fixed to the workbench surface, arranged in multiple coaxial rows and coaxially set with the workpiece installation area.

[0007] The beacon is a long strip of conductive aluminum alloy with elastic claws mounted on both ends via rotating shafts. A spring clip is provided at each position of the elastic claws. An airtight rubber ring is embedded on the side of the beacon that is in contact with the workpiece. The airtight rubber rings enclose and form a sealed adsorption cavity. The beacon has a syringe-like suction negative pressure structure inside. The suction negative pressure structure is connected to the sealed adsorption cavity. The piston end of the suction negative pressure structure is hinged to the middle of the elastic claws via a connecting rod.

[0008] The rotating support is arranged in a ring around the processing area and can rotate around the outer perimeter of the processing area. Each beacon is connected to the rotating support by a connecting rope. The beacon is equipped with a pressure relief pin, and the pressure relief pin has an L-shaped through hole.

[0009] The strong magnets on the inner wall are evenly distributed on the inner wall of the equipment shell, forming a synergistic magnetic field with the ring-shaped strong magnets on the workbench surface.

[0010] The signal generator is embedded in the beacon and includes a sensing trigger module and an audio-visual prompt module. The sensing trigger module is connected to the beacon.

[0011] Preferably, the pressure relief pin is normally in a blocked position due to the negative pressure inside the sealed adsorption chamber, and the L-shaped through hole is in a staggered and isolated state.

[0012] After processing, the rotating bracket is pulled by the connecting rope to displace the pressure relief movable pin, and the L-shaped through hole is opened, connecting the sealed adsorption chamber to the outside world to relieve pressure.

[0013] Preferably, the elastic claw can rotate bidirectionally around the pivot, and the spring clips corresponding to the elastic claws can achieve unidirectional locking when they are engaged in or disengaged from the workstation, with no loosening gaps in the limited position.

[0014] Preferably, the airtight rubber ring is made of flexible silicone material that is resistant to high temperature and cutting fluid corrosion, protruding from the beacon and fitting against the end face of the workpiece, so that the sealed adsorption cavity has no air leakage gap after fitting.

[0015] Preferably, the suction negative pressure structure adopts a piston-type suction structure, with one end of the connecting rod hinged to the piston end of the suction negative pressure structure and the other end hinged to the middle of the elastic claw, so as to realize the synchronous linkage between the flipping of the elastic claw and the negative pressure suction.

[0016] Preferably, the signal generator is a fully sealed vibration-resistant structure, and the induction trigger module is connected to the beacon.

[0017] Preferably, the connecting rope is a non-elastic wear-resistant traction rope, and the rotation traction stroke of the rotating bracket is adapted to the displacement stroke of the pressure relief movable pin.

[0018] Preferably, the inner wall strong magnet is fixedly installed on the inner wall of the equipment shell, and forms a surrounding protective magnetic field in conjunction with the magnetic field of the annular strong magnet.

[0019] A method for using a vertical turning and milling machining center includes the following steps:

[0020] S1. Select the fixing method according to the structure of the workpiece to be processed. For workpieces with positioning holes and slots, rotate the elastic claws at both ends of the beacon around the axis in the forward direction, so that the ends of the claws are engaged in the corresponding holes and slots of the workpiece. Push the spring clips into the corresponding limit slots to complete the locking of the elastic claws at the work position. For flat or irregularly shaped workpieces without positioning holes and slots, rotate the elastic claws in the reverse direction to disengage from the work position, and engage the spring clips to complete the locking. During the claw rotation process, the linkage rod pushes the piston of the suction negative pressure structure, removes the air in the sealed suction chamber to form a negative pressure, and uses the airtight rubber ring to adsorb and fix the beacon to the non-machined surface of the workpiece. Place the workpiece with the beacon clamped on the worktable surface and adjust the position to align the workpiece coaxially with the annular strong magnet.

[0021] S2. Start the spindle and cutting mechanism of the equipment to perform milling and turning machining. During the machining process, the rotary support remains stationary, the pressure relief pin is kept in the sealed position by the negative pressure of the sealed adsorption chamber, the L-shaped through hole is in a staggered isolation state, and the sealed adsorption chamber remains sealed. The strong magnet on the inner wall and the ring-shaped strong magnet form a cooperative magnetic field, the signal generator is in standby sensing state, and the normal cutting process continues to be completed under normal conditions.

[0022] S3. After the workpiece is machined, the spindle and cutting mechanism stop operating. The rotary support rotates slightly around the outer perimeter of the machining area. Simultaneously, the connecting rope pulls the pressure relief pin along the sliding channel, moving the L-shaped through-hole inside the pin to the open position. This connects the sealed adsorption chamber to the outside air, rapidly eliminating the negative pressure inside and causing the beacon to automatically detach from the workpiece surface. Release the spring clip, reset the elastic jaws, and remove the machined workpiece.

[0023] S4. If the workpiece becomes loose or shifts during processing, the beacon moves synchronously with the workpiece. After the signal generator induction trigger module captures the electromagnetic induction signal, it drives the sound and light prompt module to issue an early warning. After receiving the early warning, the operator should stop the machine in time, check for workpiece clamping faults, readjust the fixed state, and then restart processing.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] In this invention, a synergistic magnetic field is formed by a ring-shaped strong magnet and an inner wall strong magnet. Combined with a beacon conductive structure, the Lenz effect is achieved, which can delay and limit the movement of loose workpieces. At the same time, it can effectively adsorb broken debris and prevent high-speed splashing. The matching signal generator does not require an external power supply. It relies on electromagnetic induction to trigger the early warning autonomously. The early warning response is timely, without accidental triggering or delay, which greatly improves the safety of the processing site.

[0026] In this invention, the elastic jaws are rigidly linked with the suction negative pressure structure, eliminating the need for an additional negative pressure drive device and simplifying the clamping operation. After processing, the automatic pressure relief and label removal can be achieved by pulling with a rotating bracket, eliminating the tedious steps of manually disassembling the beacon, shortening the workpiece clamping and changeover cycle, adapting to batch continuous processing scenarios, and significantly improving the overall processing efficiency.

[0027] This invention is adaptable to flat, curved, and various irregularly shaped workpieces, and combines two fixing modes: mechanical snap-fit ​​and negative pressure adsorption. It can securely fasten workpieces with positioning holes and grooves, and also achieve non-destructive adsorption and fixing of precision workpieces without holes. It breaks through the limitations of traditional single fixing methods, effectively avoids scratches on the workpiece surface, and has high fixing firmness, with no risk of beacon falling off during processing.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1 to 8 The present invention provides a technical solution: a vertical milling and turning machining center, including a worktable 1, multiple annular strong magnets 2, several beacons 4, a rotary support 8, an inner wall strong magnet 13 and a signal generator 14.

[0039] The ring-shaped strong magnet 2 is locked and fixed to the worktable 1. It is arranged in multiple coaxial rows and is set coaxially with the workpiece installation area. This arrangement can make the magnetic field uniformly cover the core area of ​​the workpiece installation, laying the foundation for the subsequent formation of a synergistic magnetic field with the inner wall strong magnet 13. At the same time, it ensures that the direction of the magnetic field is matched with the workpiece clamping direction, so as not to affect the normal clamping and processing of the workpiece.

[0040] Beacon 4 is a long strip of conductive aluminum alloy. This material selection ensures the structural strength of beacon 4, adapts to the vibration environment of workshop processing, and has good conductivity, enabling it to work with magnetic fields to achieve induction and early warning.

[0041] The beacon 4 is equipped with elastic claws 5 at both ends via a rotating shaft 3. The rotating shaft 3 provides support for the flipping of the elastic claws 5. The beacon 4 is equipped with a single spring clip 12 for each set of elastic claws 5, which ensures the locking of the elastic claws 5 at the work position.

[0042] The beacon 4 has an airtight rubber ring 6 embedded on one side of the workpiece. The airtight rubber ring 6 encloses and forms a sealed adsorption cavity. The beacon 4 has a syringe-like suction negative pressure structure 7 inside. The suction negative pressure structure 7 is connected to the sealed adsorption cavity. The piston end of the suction negative pressure structure 7 is hinged to the middle of the elastic claw 5 through the connecting rod 15. This linkage structure is the core of achieving double fixation.

[0043] The rotating support 8 is arranged in a ring around the processing area and can rotate around the outer perimeter of the processing area. This movement can simultaneously pull all the beacons 4 connected to the rotating support 8, ensuring that the disassembly of multiple beacons 4 is consistent.

[0044] Each beacon 4 is connected to the rotating support 8 via a connecting rope 9. The placement of the connecting rope 9 is adapted to the rotation direction of the rotating support 8, ensuring that the rotating support 8 can effectively pull on the connecting rope 9 when it rotates. A pressure relief pin 10 is installed inside the beacon 4. The pressure relief pin 10 has an L-shaped through hole 11 inside. The design of this through hole allows for switching between blocking and conduction, thereby achieving automatic pressure relief.

[0045] The strong magnets 13 are evenly distributed on the inner wall of the equipment shell, forming a cooperative magnetic field with the ring-shaped strong magnets 2 on the workbench 1. This cooperative magnetic field covers the entire processing area.

[0046] The signal generator 14 is embedded in the beacon 4 and includes a sensing trigger module and an audio-visual prompt module. The sensing trigger module is connected to the beacon 4, and this connection method ensures that the sensing trigger module can capture the electromagnetic induction changes of the beacon 4 in real time.

[0047] Under normal conditions, the pressure relief pin 10 is in a blocked position due to the negative pressure inside the sealed adsorption chamber, and the L-shaped through hole 11 is in a staggered and isolated state. In this state, the negative pressure of the sealed adsorption chamber can be maintained to ensure the adsorption and fixation effect of the beacon 4 on the workpiece. After processing, the rotary bracket 8 pulls the pressure relief pin 10 to move through the connecting rope 9, and the L-shaped through hole 11 is opened, allowing the sealed adsorption chamber to connect with the outside world and release pressure. This process does not require manual intervention and realizes the automatic detachment of the beacon 4, thereby matching the efficiency requirements of batch processing.

[0048] The elastic jaw 5 can rotate bidirectionally around the pivot. The spring clip 12, corresponding to the elastic jaw 5, achieves unidirectional locking when it engages or disengages from the workstation, ensuring no looseness or gap in the limited position. In actual use, the bidirectional rotation of the elastic jaw 5 adapts to two different fixing modes:

[0049] When the workpiece is engaged, the end of the elastic claw 5 can be engaged into the positioning hole groove of the workpiece to achieve mechanical engagement and fixation. The one-way locking of the spring clip 12 can prevent the elastic claw 5 from loosening due to processing vibration.

[0050] When the workpiece leaves the workstation, the elastic claw 5 moves away from the workpiece surface, making room for the negative pressure adsorption mode. The locking of the spring clip 12 can fix the avoidance position of the elastic claw 5 and prevent it from interfering with the negative pressure adsorption.

[0051] In this embodiment, as Figure 1 , Figure 2 , Figures 3 to 8 As shown, the airtight rubber ring 6 is made of flexible silicone material that is resistant to high temperatures and cutting fluid corrosion. It protrudes from the beacon 4 and fits snugly against the end face of the workpiece, ensuring a leak-proof seal within the adsorption chamber after contact. This material characteristic allows the airtight rubber ring 6 to adapt to the high-temperature processing environment of the workshop, while also resisting cutting fluid corrosion and extending its service life. The protruding structural design allows the airtight rubber ring 6 to form a tight fit with the workpiece surface. Even if the workpiece surface has slight curvature, its flexibility ensures a seal, guaranteeing a leak-proof seal within the adsorption chamber and ensuring the reliability of negative pressure adsorption.

[0052] In this embodiment, as Figure 1 , Figure 2 , Figures 3 to 8As shown, the suction negative pressure structure 7 adopts a piston-type suction structure. One end of the connecting rod 15 is hinged to the piston end of the suction negative pressure structure 7, and the other end is hinged to the middle of the elastic claw 5, realizing the synchronous linkage between the flipping of the elastic claw 5 and the negative pressure suction. In actual operation, when the elastic claw 5 flips to the disengagement position, it will push the piston of the suction negative pressure structure 7 to move through the connecting rod 15, drawing out the air in the sealed adsorption chamber and forming a negative pressure; when the elastic claw 5 flips to the insertion position, the connecting rod 15 pulls the piston to reset, and the negative pressure state of the sealed adsorption chamber is released. This linkage structure does not require an additional drive device, simplifying the operation process, and at the same time realizing seamless switching between two fixed modes.

[0053] In this embodiment, as Figure 1 , Figure 2 , Figures 3 to 8 As shown, the signal generator 14 has a fully sealed vibration-resistant structure, and the induction trigger module is directly connected to the beacon 4. The fully sealed vibration-resistant structure can isolate the signal generator 14 from the cutting fluid and metal dust in the workshop, while resisting the continuous vibration generated by processing, avoiding damage to the internal modules, and ensuring long-term stable operation. The direct connection between the induction trigger module and the beacon 4 enables the module to capture the changes in the induced current of the beacon 4 in the magnetic field in real time. When the workpiece loosens and causes the beacon 4 to move, the induced current of the beacon 4 will change abruptly, and the induction trigger module will then trigger the sound and light prompt module to realize passive real-time early warning without the need for an external power supply, which is suitable for the complex wiring environment of the workshop.

[0054] In this embodiment, as Figure 1 , Figure 2 , Figures 3 to 8 As shown, the connecting rope 9 is a non-elastic, wear-resistant traction rope, and the rotational traction stroke of the rotating bracket 8 is matched with the conduction displacement stroke of the pressure relief movable pin 10. The non-elasticity ensures that the rotational stroke of the rotating bracket 8 is accurately transmitted to the pressure relief movable pin 10, avoiding traction stroke errors caused by the stretching of the connecting rope 9; the wear resistance extends the service life of the connecting rope 9, making it suitable for long-term traction operations. The matching of the rotational traction stroke of the rotating bracket 8 with the conduction displacement stroke of the pressure relief movable pin 10 ensures that when the rotating bracket 8 rotates to the preset position, the pressure relief movable pin 10 moves precisely to the conduction position of the L-shaped through hole 11, achieving precise pressure relief while avoiding damage to the pressure relief movable pin 10 due to excessive stretching.

[0055] A method for using a vertical turning and milling machining center includes the following steps:

[0056] S1. Select the fixing method according to the structure of the workpiece to be processed. For workpieces with positioning holes and slots, rotate the elastic claws 5 at both ends of the beacon 4 around the rotating shaft 3 in the positive direction so that the claw ends are inserted into the corresponding holes and slots of the workpiece. Push the spring clip 12 into the corresponding limit slot to complete the locking of the elastic claws 5 in the work position.

[0057] For flat or irregularly shaped workpieces without positioning holes or slots, the elastic jaw 5 is flipped in the opposite direction to the disengagement position, and the spring clip 12 is engaged to lock it. During the jaw flipping process, the linkage rod 15 pushes the piston of the suction negative pressure structure 7 to remove the air in the sealed suction chamber and form a negative pressure. The beacon 4 is adsorbed and fixed to the non-machined surface of the workpiece through the airtight rubber ring 6. The workpiece with the beacon clamped is placed on the worktable 1 and the position is adjusted so that the workpiece is coaxially aligned with the annular strong magnet 2.

[0058] S2. Start the equipment spindle and cutting mechanism to perform milling and turning machining;

[0059] During the processing, the rotary support 8 remains stationary, the pressure relief movable pin 10 is kept in the blocking position by the negative pressure of the sealed adsorption chamber, the L-shaped through hole 11 is in a staggered isolation state, and the sealed adsorption chamber remains sealed.

[0060] The inner wall strong magnet 13 and the ring strong magnet 2 form a cooperative magnetic field, and the signal generator 14 is in standby sensing state, continuously completing the normal cutting process under normal conditions.

[0061] S3. After the workpiece is cut and processed, the spindle and the cutting mechanism stop running. The rotary support 8 is started to rotate slightly around the outer periphery of the processing area. The pressure relief movable pin 10 is pulled synchronously along the sliding channel by the connecting rope 9, so that the L-shaped through hole 11 inside the pressure relief movable pin 10 moves to the conduction position, the sealed adsorption chamber is connected to the outside air, the negative pressure in the chamber is quickly eliminated, and the beacon 4 automatically detaches from the workpiece surface.

[0062] Release the spring clip 12, reset the elastic jaw 5, and remove the finished workpiece;

[0063] S4. If the workpiece becomes loose or shifts during processing, the beacon 4 moves synchronously with the workpiece. After the signal generator 14 senses and triggers the electromagnetic induction signal, it drives the sound and light prompt module to issue an early warning. After receiving the early warning, the operator should stop the machine in time, check for workpiece clamping faults, readjust the fixed state, and then restart processing.

[0064] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
