Description

Technical Field

[0001] This invention discloses a machining center, and more particularly relates to a hydrostatic oil circulation machining center. Background Technology

[0002] A machining center generally refers to a CNC milling machine. A machining center is an automatic machining equipment developed on the basis of a general milling machine. The two have basically the same machining process and similar structure. However, ordinary milling machines do not have automatic tool changers, while CNC milling machines with tool magazines are often called CNC machining centers.

[0003] The function of a machining center is to place and clamp the workpiece to be machined on a worktable, and then drive the cutting tool to move and feed to cut the workpiece, thereby achieving the desired shape. The movement of the tool and workpiece is guided by the X, Y, and Z axes, and is guided by guide rails to ensure smooth and stable movement of the tool and workpiece. Guide rails are generally divided into hardened rails, linear rails, and hydrostatic rails, and different types of guide rails have different effects. For example, hardened rails have a large contact surface and strong load-bearing capacity, but have high friction and low running speed, so using them in machining centers will reduce efficiency. Linear rails have poor rigidity and poor vibration resistance, and are not suitable for long-term machining and hard workpieces. Hydrostatic rails have no friction, high precision, and long service life, and are more suitable for large-scale machining. Hydrostatic rails are filled with oil to form an oil film for easy sliding, but this type of guide rail is inconvenient to maintain and cumbersome to clean. Therefore, a new solution is proposed that makes maintenance and cleaning convenient and allows for repeated use. Summary of the Invention

[0004] The purpose of this invention is to provide a hydrostatic oil circulation machining center to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hydrostatic oil circulation machining center, comprising a main body, a base, and a spindle. The base is provided with a worktable for placing workpieces. The main body is provided with a bracket connected to the spindle. The bracket is provided with a slide rail for accommodating the sliding of the spindle. The slide rail is stepped. The spindle is provided with a slider embedded in the slide rail. Oil pumps for extracting sprayed oil are provided on both sides of the slider. Baffles are provided on both sides of the slide rail to prevent the oil from flowing directly away. A first recovery tank is provided at the front end of the slide rail to accommodate and guide the flow of oil. A second recovery tank is provided on both sides of the slide rail. The first and second recovery tanks are connected. The bottoms of both the first and second recovery tanks are inclined. The main body is provided with an oil collection tank. A guide pipe connected to the oil collection tank is provided on the second recovery tank. A drive assembly for driving the bottom of the slide rail to be in an inclined state is provided at the bottom of the slide rail. The drive assembly includes a base plate at the bottom of the slide rail, which is rotatably connected to the slide rail at the middle. A pusher for pulling one end of the base plate downward is slidably connected inside the bracket. The pusher is located on the side near the second recycling tank with a guide pipe. A receiving member for supporting the base plate is provided at the bottom of the base plate. A cylinder for driving the pusher to move is provided on the bracket. A pulling member for pulling the base plate to rotate is hinged to the bottom of the base plate. The pulling member has a slot for accommodating the pusher. The pull member is provided with an abutting part at the slot that abuts against the push member. The abutting part is at the same height as the push member and is opposite to it. The slot and the push member are offset vertically. The abutting surface of the abutting part and the push member is an arc surface. The receiving member and the push member are offset front and back.

[0006] Preferably, the bottom of the base plate is provided with support members on both sides for supporting and sealing the base plate, and a spring is provided between the support member and the bracket, and the two sides of the base plate are curved surfaces.

[0007] Preferably, the blocking plate is rotatably connected to the bracket, and a rotating shaft embedded in the bracket is provided at the rotation point of the blocking plate. A first kit is snapped onto the rotating shaft. A first cylinder is provided with a connecting piece embedded in the bracket and slidably connected to the bracket. The connecting piece is connected to a pushing member. A moving block for the first blocking kit and the blocking plate to rotate is provided on the connecting piece. A torsion spring for pushing the rotating shaft to drive the blocking plate to rotate is provided between the rotating shaft and the bracket.

[0008] Preferably, a second component is engaged with the first component on the rotating shaft. The first component has a limiting groove for accommodating the embedded movable block, and the second component has an arc-shaped groove communicating with the limiting groove. The movable block is cylindrical.

[0009] Preferably, the movable block is slidably connected to the connector, the bracket is provided with a groove for accommodating the movable block, and a protrusion for pushing the movable block to move up and down is slidably connected in the groove. The side of the protrusion near the first component is an arc surface, and the other side is an inclined surface. A second spring is provided between the protrusion and the bracket.

[0010] Preferably, the moving block moves forward along the arc surface to push the moving block to open the slide groove, and when the moving block moves backward to reset, it moves up and rises along the inclined surface. The first component is larger than the second component, and the depth of the limiting groove is greater than that of the arc groove.

[0011] Preferably, the baffle plate is provided with an oil drain hole to accommodate the oil flow, and the oil drain hole is higher than the bottom plate, and the guide pipe is higher than the bottom of the second recovery tank.

[0012] Compared with the prior art, the beneficial effects of the present invention are: Firstly, by applying this device to a machining center, when the machining center is driven to process, it moves along different axes. The slider moves along the slide rail. At this time, the oil pumps on the left and right sides of the slider are turned on, and oil is continuously drawn from the oil collection tank through the oil pipe and input into the slide rail. The slide rail is filled with oil, and a load-bearing oil film is formed between the slide rail and the track surface. It is in a pure liquid friction state. The oil pump is open, and oil is continuously output into the slide rail. Excess oil overflows from the baffle plate. When the slider moves, it also pushes the oil out and into the second recovery tank on the side. Then, it enters the first recovery tank from the second recovery tank. Since the bottom of the first and second recovery tanks is inclined, the oil will converge from the second and first recovery tanks to the bottom guide pipe and re-enter the oil collection tank to be drawn again, thus achieving the effect of recycling. Secondly, when maintenance is required after use, to prevent the oil from deteriorating and failing due to prolonged standing and lack of sealing, the oil is generally not left to stand for extended periods after use. Therefore, after use, the cylinder moves the pushing component, which in turn pushes the pulling component downwards. This causes the pulling component to move the hinged base plate downwards, with the end of the base plate with the pulling component moving downwards. The entire base plate rotates around the middle and tilts, allowing all the oil to be poured out and enter the recovery tank on the side. The oil then flows along the recovery tank and converges into the guide pipe for recycling. This design facilitates recycling by tilting the base plate, avoiding the inconvenience caused by the slow flow of oil in existing technologies that require manual pushing and cleaning. Thirdly, when all the oil is recovered, the bottom plate tilts and the side baffles open automatically, facilitating the flow of oil and preventing oil from accumulating due to obstruction by the baffles. Over time, the oil deteriorates and loses its lubricating effect. The automatic opening makes it easy to recover and circulate the oil. Attached Figure Description

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. In this description, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Obviously, the described embodiments are only some embodiments of the present invention, 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.

[0016] A hydrostatic oil circulation machining center, such as Figures 1-9As shown, the device includes a main body 1, a base 2, and a spindle 3. The base 2 is equipped with a worktable 4 for placing workpieces. The main body 1 is equipped with a bracket 6 connected to the spindle 3. The bracket 6 is equipped with a slide rail 5 to accommodate the sliding of the spindle 3. Under normal use, the slide rail 5 is filled with oil by the oil pump 8, so that an oil film is formed between the slider 7 and the slide rail 5. This allows the slider 7 to move and ensures that the surface temperature of the slider 7 and the slide rail 5 is balanced by the oil. The surfaces of the slide rail 5 are in a pure liquid friction state, which ensures stable movement without friction, high precision, and long service life. However, after a period of use, the oil needs to be recycled and cleaned to avoid oil oxidation and pollution affecting the lubrication, load-bearing capacity, and smoothness of movement of the guide rail. Furthermore, dust, metal particles, or moisture entering the oil will reduce the quality of the oil film and increase friction and wear. Therefore, the oil needs to be replaced. However, replacement is inconvenient and the oil cannot be effectively drained. The slide rail 5 is stepped, and the main shaft 3 has a slider 7 embedded in the slide rail 5. Oil pumps 8 for drawing out sprayed oil are located on both sides of the slider 7. Baffle plates 9 are located on both sides of the slide rail 5 to prevent direct oil flow. A first recovery tank 10 is located at the front end of the slide rail 5 to accommodate and guide the flow of oil. Second recovery tanks 11 are located on both sides of the slide rail 5, and the first recovery tank 10 and the second recovery tank 11 are connected. The bottoms of both the first recovery tank 10 and the second recovery tank 11 are inclined. The main body 1 of the equipment has an oil collection tank 12. A guide pipe 13 connected to the oil collection tank 12 is located on the second recovery tank 11. A drive assembly is located at the bottom of the slide rail 5 to drive the bottom of the slide rail 5 into an inclined state. Under normal use, the oil pumps 8 are located on the left and right sides of the slider 7, and the oil pumps 8 continuously input oil in an open manner. The baffle plates 9 prevent insufficient oil. Furthermore, because the main shaft 3 is large, the stepped design of the slide rail 5 increases the load-bearing capacity. The oil... As the slider 7 moves left and right, excess oil can overflow from the baffle plate 9, or normally be discharged through the drain hole 34 of the baffle plate 9, preventing excessive pressure. The overflowing oil first enters the second recovery tank 11. The bottom of the second recovery tank 11 is inclined to ensure that the oil can continue to flow into the first recovery tank 10. Since there are recovery tanks 11 on both sides, the oil overflowing from the slider 7 will enter the second recovery tank 11 and then converge into the first recovery tank 10. Finally, due to the stepped arrangement of the slide rail 5 of the bracket 6, the oil can enter the lowest recovery tank 11 along the uppermost recovery tank 11 and converge into the second recovery tank 11 with the guide pipe 13. The inclination angle of the first recovery tank 10 is that the end closer to the guide pipe 13 is lower and the other end is higher, so as to ensure that the oil entering can converge at the guide pipe 13 and be recovered into the oil collection tank 12 along the guide pipe 13, thereby achieving circulation and avoiding waste.

[0017] The drive assembly includes a base plate 14 located at the bottom of the slide rail 5, with the middle of the base plate 14 rotatably connected to the slide rail 5. A pusher 15 for pulling one end of the base plate 14 downwards is slidably connected inside the bracket 6. The pusher 15 is located on the side near the recovery tank 11 with the guide pipe 13. A receiving member 16 is provided at the bottom of the base plate 14 to support it. A cylinder 17 is provided on the bracket 6 to drive the pusher 15. A pulling member 18 is hinged to the bottom of the base plate 14 to pull it rotate. Furthermore, when maintenance and cleaning are required after prolonged use, and the oil is drained, the cylinder 17 activates the pusher 15 to move synchronously, causing the pusher 15 to laterally engage with the pulling member 18. Within 8, the pull member 18 is pushed downward, causing the pull member 18 to move the hinged base plate 14 downward. This downward movement of the hinged pull member 18 can cause the base plate 14 to rotate and move downward along the hinge point without getting stuck. Since the pull member 18 is located on the side of the center of the base plate 14 near the baffle plate 9, the base plate 14 moves downward near the baffle plate 9, and the other end of the base plate 14 is raised along the center, thus presenting an inclined state, so that the internal oil pours down to the lower place, which facilitates the discharge of oil. Secondly, the support member 16 at the bottom of the base plate 14 moves away at the same time, canceling the support for the base plate 14. This setting allows the oil to flow away along the side baffle plate 9, which facilitates the flow of oil and makes cleaning easier. The pulling member 18 is provided with a slot 19 for accommodating the insertion of the pushing member 15. The pulling member 18 has an abutment portion 20 located at the slot 19 that abuts against the pushing member 15. The abutment portion 20 is at the same height as the pushing member 15 and is opposite to it. The slot 19 and the pushing member 15 are vertically offset. The abutment surface of the abutment portion 20 and the pushing member 15 is curved. The receiving member 16 is offset from the pushing member 15. When the pushing member 15 moves, it first abuts against the opposite abutment portion 20, and then pushes the abutment portion 20 downwards along its curved surface, causing the entire pulling member 18 to move downwards. This causes the pulling member 18 to rotate along the hinge point, tilting the base plate 14. Simultaneously, the offset slot 19 moves to be opposite the pushing member 15, allowing the pushing member 15 to continue moving, embedding itself into the slot 19, and moving along the slot 19, thus achieving the effect of pulling the base plate 14. Secondly, when cylinder 17 is not driven, the receiving part 16 is located at the bottom of the base plate 14, which serves to support the base plate 14 and ensure that the base plate 14 has sufficient support. When cylinder 17 moves, the receiving part 16 is first pushed to offset the base plate 14 to support the base plate 14. Then the pushing part 15 abuts against the abutting part 20 of the pulling part 18, so that the base plate 14 can be pulled down immediately after it is disengaged from the support, avoiding jamming. Conversely, when resetting, cylinder 17 moves backward, the pushing part 15 cancels the push on the pulling part 18 and disengages from the slot 19, and the receiving part 16 abuts against the base plate 14 again to achieve the effect of supporting the receiving part 16 again.

[0018] The bottom of the base plate 14 has support members 21 on both sides for supporting and sealing the base plate 14. A spring 22 is provided between the support member 21 and the bracket 6. The two sides of the base plate 14 are curved. Under normal conditions, the receiving member 16 and the support member 21 work together to provide support. The support member 21 is distributed on the left and right sides of the base plate 14. When the base plate 14 rotates, the end near the blocking plate 9 moves down and the other end moves up. The curved sides of the base plate 14 prevent jamming during rotation. As a result, one end of the support member 21 is pushed to compress the spring 22 and move down. The lowered base plate 14 will still abut and stick tightly to the support member 21 to prevent oil from leaking to the bottom of the base plate 14. Secondly, the raised part of the base plate 14 will be pushed up by the spring 22 and also stick to the base plate 14. The edges of the base plate 14, the blocking plate 9, and the support member 21 are all sealed with sealing strips to reduce leakage and increase airtightness. The above-mentioned design ensures that when maintenance and oil replacement are required, the tilted design allows for easy pouring and flow of the internal oil, preventing excessive oil buildup and difficulty in cleaning when the system is horizontal. Furthermore, it prevents excessive residual oil from mixing with new oil, which could reduce lubrication performance and accelerate component wear. The baffle plate 9 is rotatably connected to the bracket 6. The baffle plate 9 has a rotating shaft 23 embedded in the bracket 6 at its rotation point. The rotating shaft 23 is fitted with a kit 24. The cylinder 17 has a connector 25 embedded in the bracket 6 and slidably connected to the bracket 6. The connector 25 is connected to the pusher 15. The connector 25 has a moving block 26 that blocks the rotation of the kit 24 and the baffle plate 9. A torsion spring 27 that pushes the rotating shaft 23 to drive the baffle plate 9 to rotate is provided between the rotating shaft 23 and the bracket 6. When the base plate 14 needs to be tilted, the cylinder 17 drives the pusher 15 to move, which in turn drives the connector 25 to move. The connector 25 then drives the receiving part 16 and the pusher 15 to move. When the connector 25 moves, the moving block 26 slides synchronously. When the moving block 26 moves, it first moves along the limiting groove 29 of the kit 24, cancels the limiting of the kit 24 and disengages from the limiting groove 29 of the kit 24. Then, after the kit 24 is released from the limiting, the internal torsion spring 27 is released, which drives the rotating shaft 23 to rotate, which drives the kit 24 and the baffle plate 9 to rotate synchronously. The baffle plate 9 unfolds and cancels the side closure of the slide rail 5. In this state, when the connector 25 drives the pusher 15 to drive the base plate 14 to move down, the side opens, allowing the oil to flow along the tilted base plate 14 and flow away along the opening of the baffle plate 9. Secondly, the oil flows to the recovery tank 11 through the arc edge of the base plate 14.

[0019] A second component 28, which fits snugly against a first component 24, is engaged with a rotating shaft 23. The first component 24 has a limiting groove 29 for accommodating the embedded movable block 26. The second component 28 has an arc-shaped groove 30 communicating with the limiting groove 29. The movable block 26 is cylindrical. The movable block 26 is slidably connected to the connecting piece 25. The bracket 6 has a sliding groove 31 for accommodating the embedded movable block 26. A protrusion 32 for pushing the movable block 26 up and down is slidably connected within the sliding groove 31. The side of the protrusion 32 closest to the first component 24 is arc-shaped, and the other side is inclined. A second spring 33 is provided between the protrusion 32 and the bracket 6. The first component 24 is larger than the second component 28, and the depth of the limiting groove 29 is greater than the arc-shaped groove 30. When the moving block 26 moves forward along the arc surface, it pushes the moving block 26 to open the slide groove 31. When the moving block 26 moves backward to reset, it moves upward along the inclined surface and is raised. Then, the rotating shaft 23 is driven to rotate by the torsion spring 27, which will synchronously drive the second component 28 to rotate as well. The arc groove 30 of the second component 28 is connected to the limiting groove 29. When the moving block 26 is driven by the connecting piece 25, the bottom of the moving block 26 moves along the bottom of the slide groove 31 and abuts against the arc surface of the protrusion 32, pushing the protrusion 32 to compress the internal spring 33, thereby opening the slide groove 31. The protrusion 32 passes through and moves along the limiting groove 29, disengaging from the limiting groove 29. After disengaging from the limiting groove 29, the moving block 26 cannot be inserted into the arc-shaped groove 30 due to distance, nor will it abut against the second component 28. Therefore, it will not obstruct the second component 28, allowing the rotating shaft 23 to rotate under the influence of the torsion spring 27. Furthermore, after the moving block 26 reaches the end of the slide groove 31, it disengages from the slide groove 31. When it stops abutting against the protrusion 32, the protrusion 32 is pushed back to its original position by the second spring 33, re-closing the slide groove 31. In any case, after the connecting piece 25 resets, the moving block... Moved backward, the movable block 26 moves along the inclined surface of the protrusion 32 and continuously rises in height. At this time, the movable block 26 slides up and down with the connecting piece 25, and the raised length of the movable block 26 is sufficient to embed into the arc-shaped groove 30 of the second component 28. After rotation, the bottom of the arc-shaped groove 30 of the second component 28 is located on the path of the movable block 26's movement. This ensures that the movable block 26 can be repositioned and embedded into the arc-shaped groove 30, and that the second component 28, the first component 24, and the rotating shaft 23 are connected along the arc-shaped groove 30. The blocking plate 9 rotates to close the slide rail 5 again and compresses the torsion spring 27. Then, the moving block 26 returns to its original position after disengaging from the arc groove 30 and continues to move along the connected limiting groove 29 and reaches the limit on the kit 24, preventing the kit 24 from being pushed open by the elastic force of the torsion spring 27. After the moving block 26 is embedded in the limiting groove 29, it also moves to the initial position of the protrusion 32 and falls off and re-aligns with the arc surface of the protrusion 32. This setting ensures that the blocking plate 9 can be limited, and the blocking plate 9 can also be closed when it is reset.

[0020] The baffle plate 9 is equipped with an oil drain hole 34 to accommodate the outflow of oil, and the oil drain hole 34 is higher than the bottom plate 14, while the guide pipe 13 is higher than the bottom of the recovery tank 11. The design of the oil drain hole 34 ensures normal use, allowing the open-type oil pump 8 to output oil stably along the oil drain hole 34, avoiding excessive pressure changes. Secondly, being higher than the bottom plate 14 prevents the oil from being completely drained and also prevents impurities at the bottom from easily flowing and being recycled. Furthermore, the guide pipe 13 is higher than the bottom of the recovery tank 11, which can also isolate impurities and cutting debris from splattering at the bottom and allow them to be disposed of uniformly during cleaning and maintenance.

[0021] Finally, using this structure, the setup of Kit 1 (24) and Kit 2 (28) ensures that the baffle plate 9 opens quickly and first when driven by cylinder 17. After the restriction is lifted, the torsion spring 27 pushes quickly. Compared to extending Kit 2 (28) with the arc groove 30, this setup allows for faster opening. Opening before the bottom tilts allows the internal oil to flow out slowly, rather than opening after the bottom tilts and the oil has already accumulated at the baffle plate 9, causing the oil to gush out and splash. Opening first ensures the oil flows out slowly along the baffle plate 9 and is recycled as much as possible, reducing waste. Furthermore, the linearly set limiting groove 29 in Kit 1 (24) ensures that the reset cylinder is not moved by the torsion spring 27 when stationary, preventing accidental external contact. Secondly, the above dimensions are for demonstration purposes; in actual production, the proportions can be adjusted according to the product size to ensure support and linkage.

[0022] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
