Description

Technical Field

[0001] The present invention relates to the technical field of machining, in particular to a grinding wheel type milling and grinding compound machine. Background Art

[0002] Milling and grinding are two common finishing processes for large flat surfaces of steel plates. Milling is primarily used to remove large allowances and achieve a higher degree of flatness, while grinding is used to further improve surface finish and ensure the ultimate precision of the workpiece. However, traditional machining methods typically employ separate milling and grinding processes, with roughing and semi-finishing performed on a milling machine before transfer to a grinding machine for finishing. This step-by-step approach not only increases the turnaround time between processes and reduces production efficiency, but can also lead to deviations in the machining datum due to secondary clamping or environmental factors during handling, affecting the final machining accuracy.

[0003] In addition, resin grinding wheels are a commonly used grinding tool in grinding processes. Resin grinding wheels are reinforced with glass fiber mesh or metal rings during manufacturing. Their directionality needs to match the direction of rotation. Reversal will reduce the strength. The resin bond has also been optimized according to the force direction during curing. Reversal may accelerate the shedding of abrasive particles. Therefore, resin grinding wheels usually need to rotate in a specified direction. However, in reciprocating grinding processes, the workpiece or grinding wheel needs to move back and forth to achieve uniform grinding of large surfaces. When the grinding wheel is in the reverse stroke (such as the return stroke), since the direction of rotation is fixed, the cutting direction of the grinding wheel is opposite to the feed direction, that is, reverse grinding, which weakens the cutting action of the abrasive particles and even causes extrusion, scratching, etc., which not only reduces the grinding efficiency, but may also cause surface scratches, burns or uneven grinding textures, affecting the surface quality and processing consistency of the workpiece. Summary of the Invention

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

The first slide 3 is provided with a second linear motor, the first slide 3 is fixedly connected to the stator of the second linear motor, and the third slide 31 is fixedly connected to the mover of the second linear motor. The second linear motor is used to enable the third slide 31 to slide relative to the first slide 3. The third slide 31 is provided with a milling tool 33 and a second motor 32 that drives the milling tool 33 to rotate. The milling tool 33 is rotatably connected to the bottom of the third slide 31, and the rotation axis of the milling tool 33 extends in the Z direction. The second linear motor adjusts the distance between the milling tool 33 and the workpiece mounting table 10 by driving the third slide 31 to move in the Z direction.

[0027] The second slide 4 is provided with a fourth slide 41, which is slidably connected to the second slide 4 in the Z direction. The second slide 4 is provided with a third linear motor, the second slide 4 is fixedly connected to the stator of the third linear motor, and the fourth slide 41 is fixedly connected to the mover of the third linear motor. The third linear motor is used to enable the fourth slide 41 to slide relative to the second slide 4. A workbench 5 is fixedly mounted on the second slide 4. The workbench 5 is provided with a grinding wheel 6 and a first motor 11 that drives the grinding wheel 6 in rotation. The grinding wheel 6 is rotatably connected to the bottom of the workbench 5. The third linear motor adjusts the distance between the grinding wheel 6 and the workpiece mounting table 10 by driving the fourth slide 41 to move in the Z direction.

[0028] Furthermore, the first motor 11 is fixedly mounted on the second slide 4. The output shaft of the first motor 11 is fixedly connected to the second shaft 111, and the second pulley 112 is fixedly sleeved on the second shaft 111. The grinding wheel 6 is fixedly sleeved on the first shaft 61. Two brackets 51 are provided on the workbench 5. The first shaft 61 is rotatably connected to the two brackets 51, and the grinding wheel 6 is located between the two brackets 51. The first shaft 61 and the second shaft 111 are arranged parallel to each other. The first pulley 62 is fixedly sleeved on the first shaft 61. The first pulley 62 and the second pulley 112 are connected by a synchronous belt 17. In this embodiment, the first pulley 62 and the second pulley 112 are both gears, and the synchronous belt 17 is a toothed belt.

[0029] In this embodiment, the first motor 11 can drive the second shaft 111 and the second pulley 112 to rotate, and the first pulley 62 rotates synchronously with the second pulley 112, thereby rotating the first shaft 61 and the grinding wheel 6. The grinding wheel 6 is a grinding wheel that grinds the workpiece through rotation. In this embodiment, the rotation axis of the grinding wheel 6 extends in the X direction, and the axes of the first shaft 61 and the second shaft 111 also extend in the X direction.

[0030] The gantry of the grinding wheel type milling and grinding compound machine in this embodiment is provided with a milling tool 33 and a grinding wheel 6. The milling tool 33 is used for milling large flat workpieces, and the grinding wheel 6 is used for grinding large flat workpieces, thereby realizing a composite processing of milling and grinding, which can save the workpiece transfer process between the milling machine and the grinding machine, and improve the processing efficiency.

[0031] Moreover, in this embodiment, the grinding wheel 6 of the grinding wheel type milling and grinding compound machine is installed between two brackets 51. The two brackets 51 directly support the grinding wheel 6 stably. During processing, a grinding wheel 6 with a larger width can be selected for grinding, thereby increasing the grinding area of ​​a single stroke, saving the number of grinding knife changes, and improving the grinding efficiency.

[0032] For example, the traditional grinding wheel spindle is supported on one side, and thin grinding wheels are generally installed for processing, such as a grinding wheel with a width of 90mm. When processing a steel plate with a size of 1600×1000, the thin grinding wheel with a width of 90mm needs to be connected with the tool 11 times, which takes a long time to go back and forth, consumes a lot of electricity, and has a slow processing speed. The present grinding wheel type milling and grinding compound machine is used to process a steel plate with a size of 1600×1000. The milling tool 33 is first used to process the surface of the steel part, and then the grinding wheel is used to grind it. Since the grinding wheel of the present milling and grinding compound machine is supported on both sides, a wide grinding wheel with a width of 255mm can be stably installed between the brackets 51. When the wide grinding wheel is used to grind the steel part, only four times of connection are required to complete the entire plane grinding, which has high processing efficiency and saves energy.

[0033] Example 2 refer to Figure 3 Referring to the figure, unlike Example 1, the fourth slide 41 in this embodiment is not directly connected to the workbench 5. Instead, a first support frame 7 is fixedly mounted on the fourth slide 41, and the workbench 5 is mounted inside the first support frame 7. The first support frame 7 is cylindrical, and the axis of the first support frame 7 extends in the Z-axis direction. In this embodiment, the Z-axis is the first direction. The first support frame 7 is fixedly mounted to the fourth slide 41 via the third support frame 18.

[0034] refer to Figure 4-Figure 6 The inner wall of the first support frame 7 is provided with a first slide groove 71, which is annular. Two symmetrically distributed sliders 12 are provided inside the first slide groove 71, and the two sliders 12 slide with the first slide groove 71 respectively. The workbench 5 is fixedly connected between the two sliders 12 by a connecting rod 121, and the workbench 5 is rotatably connected to the first support frame 7. The workbench 5 is eccentrically arranged inside the first support frame 7. When the workbench 5 is installed, the intersection of the axis center and the center diameter surface of the grinding wheel 6 is kept at the axis of the first support frame 7. When the workbench 5 is flipped 180° relative to the first support frame 7, the intersection of the axis center and the center diameter surface of the grinding wheel 6 is the center point of the grinding wheel 6. The grinding wheel 6 flips with the center point as the rotation center. After the workbench 5 rotates, the position of the grinding wheel 6 remains unchanged. After the workbench 5 flips, the system does not need to perform secondary positioning on the grinding wheel 6 and can directly proceed to the next stroke processing without affecting the original stroke setting of the machine tool.

[0035] Furthermore, a second functional cylinder 16 is mounted on the top of the first support frame 7. The axis of the second functional cylinder 16 is in the Z-axis direction. The lower portion of the second functional cylinder 16 is a working end, which extends into the interior of the first chute 71. A positioning rod is connected to the working end of the second functional cylinder 16. A positioning hole 122 is provided on the top of the slider 12. The second functional cylinder 16 can drive the positioning rod to move in the Z-axis direction, so that the positioning rod can be inserted into the positioning hole 122, thereby positioning the slider 12 in the first chute 71, thereby maintaining the position of the workbench 5 in the first support frame 7.

[0036] For further reference, Figure 7-Figure 8 A mounting plate 113 is provided at the end of the second shaft body 111, and the mounting plate 113 is coaxially fixedly connected to the end of the second shaft body 111. A third functional cylinder 151 is provided on the mounting plate 113, and one end of the third functional cylinder 151 is fixedly connected to the mounting plate 113, and the other end of the third functional cylinder 151 is a working end. The working end of the third functional cylinder 151 is fixedly connected to the first combining plate 15, and the first combining plate 15 is annular.

[0037] Furthermore, a fourth shaft 114 is provided at the end of the second shaft 111, and the fourth shaft 114 is coaxially fixedly connected to the end of the second shaft 111. The fourth shaft 114 passes through the inner hole of the first coupling plate 15 and is connected to the third shaft 91. The third shaft 91 and the fourth shaft 114 are coaxially rotatably connected. One end of the third shaft 91 is fixedly sleeved on the first gear 9, and the other end of the third shaft 91 is fixedly connected to the second coupling plate 92. The second coupling plate 92 is arranged opposite and parallel to the first coupling plate 15. The opposing surfaces of the second coupling plate 92 and the first coupling plate 15 are in contact with each other to form a static friction bond, thereby achieving synchronous rotation of the first gear 9 and the second shaft 111.

[0038] In this embodiment, the third functional cylinder 151 is used to drive the first coupling plate 15 toward or away from the second coupling plate 92, causing the second coupling plate 92 to contact or separate from the first coupling plate 15. When the second coupling plate 92 separates from the first coupling plate 15 and the second shaft 111 rotates, the first gear 9 does not rotate. When the second coupling plate 92 contacts the first coupling plate 15, the second shaft 111 rotates with the first gear 9 via the mounting plate 113, the first coupling plate 15, the second coupling plate 92, and the third shaft 91.

[0039] refer to Figure 5 , the above-mentioned first support frame 7 is also provided with a second slide groove 72, and the second slide groove 72 is located below the first slide groove 71, and the second slide groove 72 is also annular. A movable sleeve 8 is provided inside the second slide groove 72, and the movable sleeve 8 is slidably connected to the first support frame 7 in the Z direction. The inner wall of the movable sleeve 8 is fixedly connected with a first gear ring 81 and a second gear ring 82, and the first gear ring 81 and the second gear ring 82 are respectively coaxially arranged with the movable sleeve 8, and the first gear ring 81 is located above the second gear ring 82. The teeth of the first gear ring 81 and the second gear ring 82 are arranged opposite to each other, and the first gear 9 is located between the first gear ring 81 and the second gear ring 82. The teeth of the first gear 9 match the teeth of the first gear ring 81 and the second gear ring 82 to form meshing. In this embodiment, the first gear 9 is a bevel gear.

[0040] Furthermore, the bottom of the first support frame 7 is fixedly connected to the second support frame 14. The second support frame 14 is provided with a first functional cylinder 13. The axis of the first functional cylinder 13 extends in the z-direction. The upper portion of the first functional cylinder 13 is a working end. The working end of the first functional cylinder 13 extends into the interior of the second chute 72 and is fixedly connected to the movable sleeve 8. The first functional cylinder 13 can drive the movable sleeve 8 to move axially in the z-direction, thereby causing the first ring gear 81 or the second ring gear 82 to mesh with the first gear 9.

[0041] The grinding wheel 6 in this embodiment is a resin grinding wheel. When the grinding wheel 6 is in operation, the rotational direction of the grinding wheel 6 and the first shaft 61 is fixed, and therefore the rotational direction of the second shaft 111 and the first gear 9 is also fixed. When the first gear 9 is engaged with the first ring gear 81, the worktable 5 will rotate in the direction W2. When the first gear 9 is engaged with the second ring gear 82, the worktable 5 will rotate in the direction W1. The direction W2 is opposite to the direction W1. Therefore, the worktable 5 can rotate in different directions relative to the first support frame 7.

[0042] In this embodiment, when the grinding wheel 6 performs a linear reciprocating path grinding process, after completing the first stroke, it needs to perform a second stroke in the opposite direction. The movement direction of the grinding wheel 6 relative to the workpiece changes. Since the rotation direction of the resin grinding wheel is fixed, if the grinding wheel 6 is directly reversed, the grinding wheel 6 will perform a reverse grinding process on the workpiece. In this embodiment, when the grinding wheel 6 on the workbench 5 completes the first stroke, before performing the second stroke, the workbench 5 is flipped 180 degrees to adjust the direction of the grinding wheel 6 to achieve the rotation of the grinding wheel 6, so as to maintain the grinding wheel 6 in the forward grinding state during the second stroke, avoid the occurrence of reverse grinding, and improve the stability of the grinding process quality.

[0043] During actual operation, when the workbench 5 is flipped, it can be flipped unidirectionally in the W1 direction or the W2 direction each time. Multiple unidirectional flips in the W1 direction or multiple unidirectional flips in the W2 direction will result in a 360° rotation of the workbench 5, causing entanglement of the electrical wiring on the workbench 5, requiring more investment in a stable power supply for the workbench 5. In this embodiment, the workbench 5 can be intermittently engaged with the two gear rings. When the tool is connected, the workbench 5 can be flipped 180° back and forth, avoiding the inconvenience of external power connection caused by the continuous unidirectional flipping of the workbench 5.

[0044] The grinding process of the grinding wheel type milling and grinding compound machine in this embodiment is as follows: Step 1: Processing of the first stroke. Figure 5 and Figure 10 When the grinding wheel 6 is performing the first stroke processing, the position of the slider 12 is fixed by the positioning rod of the second functional cylinder 16, the workbench 5 is fixed in the position inside the first support frame 7, and the second combining plate 92 is separated from the first combining plate 15; The first motor 11 drives the second shaft 111 and the second pulley 112 to rotate, while the first gear 9 does not rotate. The first pulley 62 rotates synchronously with the second pulley 112, thereby driving the rotation of the first shaft 61 and the grinding wheel 6. The workpiece mounting table 10 moves relative to the base 1, and the workpiece on the workpiece mounting table 10 can move relative to the workbench 5 and the grinding wheel 6. The grinding wheel 6 and the workpiece move relative to each other in the V1 direction, and the grinding wheel 6 performs a positive grinding process on the workpiece.

[0045] Step 2: The workbench 5 is turned over once. After the first stroke is completed, the grinding wheel 6 leaves the workpiece but the first motor 11 remains in operation. The second functional cylinder 16 contracts, and the positioning rod at the working end of the second functional cylinder 16 releases the limit on the slider 12. The third functional cylinder 151 drives the first combining plate 15 to move, so that the second combining plate 92 is attached to the first combining plate 15. The second shaft 111 at the output end of the first motor 11 rotates with the first gear 9 through the mounting plate 113, the first combining plate 15, the second combining plate 92, and the third shaft 91. At this time, the first gear 9 is engaged with the second ring gear 82, and the first gear 9 moves relative to the second ring gear 82 to form the rotation of the worktable 5 in the W1 direction. When the worktable 5 rotates 180°, that is, the worktable 5 completes a 180° forward flip, at this time, the second functional cylinder 16 extends, and the positioning rod at the working end of the second functional cylinder 16 limits the slider 12 again. The third functional cylinder 151 drives the first combining plate 15 to move, so that the second combining plate 92 is separated from the first combining plate 15. When the worktable 5 completes the flip, the grinding wheel 6 completes the reversal.

[0046] Step 3: Processing of the second stroke. Figure 9 and Figure 10 The grinding wheel 6 performs the second stroke processing, the first motor 11 drives the second shaft 111, the first shaft 61 and the grinding wheel 6 to rotate, and the first gear 9 does not rotate. A relative movement in the direction V2 occurs between the grinding wheel 6 and the workpiece, and the grinding wheel 6 performs a forward grinding process on the workpiece.

[0047] Step 4: The workbench 5 is turned over for the second time. After the second stroke is completed, the grinding wheel 6 leaves the workpiece but the first motor 11 remains in operation. The second functional cylinder 16 contracts, and the positioning rod at the working end of the second functional cylinder 16 releases the limit on the slider 12. Figure 9 , the first functional cylinder 13 drives the movable sleeve 8 to move axially, so that the first gear 9 is engaged with the first gear ring 81, and the third functional cylinder 151 drives the first combining plate 15 to move, so that the second combining plate 92 is in contact with the first combining plate 15, and the first functional cylinder 13 drives the first gear 9 to rotate, and the first gear 9 moves relative to the first gear ring 81 to form the rotation of the workbench 5 in the W2 direction. When the workbench 5 rotates 180°, that is, the workbench 5 completes a 180° reverse flip, at this time, the second functional cylinder 16 extends, and the positioning rod at the working end of the second functional cylinder 16 limits the slider 12 again, and the third functional cylinder 151 drives the first combining plate 15 to move, so that the second combining plate 92 is separated from the first combining plate 15. When the workbench 5 completes a 180° flip, the grinding wheel 6 completes reversal again.

[0048] Repeating steps 1 to 4 completes the linear reciprocating grinding of the workpiece by the grinding wheel 6. Since the grinding wheel 6 reverses direction between two strokes, the grinding wheel 6 can continuously perform forward grinding on the workpiece, and the grinding quality is more stable.

[0049] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
