SUMMARY

[0004] The purpose of the present application is to provide a gantry machining center with noise reduction function to solve the problems in the prior art.

[0005] To achieve the above purpose, the present application provides the following technical scheme: A gantry machining center with noise reduction function, the gantry machining center comprises a supporting mechanism, a translation mechanism, a horizontal movement mechanism, a lifting mechanism, a cutting assembly, a noise reduction mechanism and a balancing mechanism, the supporting mechanism is provided with the translation mechanism and the horizontal movement mechanism, the horizontal movement mechanism and the lifting mechanism are tightly connected, one side of the lifting mechanism is provided with the cutting assembly, the horizontal movement mechanism and the balancing mechanism are tightly connected, and the supporting mechanism is provided with the noise reduction mechanism.

[0006] The noise reduction mechanism is fixed on the supporting mechanism, which is used for protecting the whole device and blocking the sound emitted by the internal machinery, so as to achieve the effect of noise reduction. The workpiece to be processed is placed on the translation mechanism, which can drive the workpiece above to move position, so as to process different positions of the workpiece. The cutting assembly is fixed on one side of the lifting mechanism, which is used for processing workpiece. The lifting mechanism can drive the cutting assembly to move up and down, so as to cut the workpiece up and down. The lifting mechanism is fixed on the horizontal movement mechanism, and the balancing mechanism is used for balancing the gravity center of the lifting mechanism.

[0007] Further, the supporting mechanism comprises a rack and a machine tool, the rack is provided with the machine tool, the machine tool is provided with the translation mechanism, and the machine tool and the noise reduction mechanism are tightly connected.

[0008] The frame supports the entire device, the machine tool is fixed above the frame, the machine tool is used to determine the position of the translation mechanism, and the noise reduction mechanism is located above the machine tool to shield other internal mechanisms and prevent noise from escaping.

[0009] Furthermore, the translation mechanism includes a worktable, a translation slide rail, a translation motor, a translation lead screw, and a base. There are two sets of translation slide rails, which are symmetrically arranged on the machine tool. The worktable and the translation slide rails are slidably connected. The translation motor is fixed to one end of the machine tool and placed between the two sets of translation slide rails. The output end of the translation motor is fastened to the translation lead screw. The translation lead screw passes through the worktable and is threadedly connected to the worktable. The translation lead screw is rotatably connected to the base, and a transverse movement mechanism is provided on the base.

[0010] The base is fixed above the machine tool, and two sets of translation slides are fixed above the base. A translation motor and a translation screw are set in the middle of the two sets of translation slides. The worktable is installed above the base. The translation motor outputs torque to drive the translation screw to rotate. Through the threaded connection between the translation screw and the worktable, the worktable can move back and forth on the translation screw. The workpiece to be processed placed on the worktable can move with the back and forth movement of the worktable, thereby processing different positions.

[0011] Furthermore, the transverse movement mechanism includes columns, a main crossbeam, a transverse motor, transverse slide rails, a transverse lead screw, and a sliding plate. There are two sets of columns, symmetrically arranged on the base. The main crossbeam is located between the two sets of columns. A transverse motor and a transverse slide rail are located on one side of the main crossbeam. There are two sets of transverse slide rails, located on both sides of the transverse motor. The transverse slide rails and the sliding plate are slidably connected. The output end of the transverse motor is fastened to the transverse lead screw. The transverse lead screw passes through the sliding plate and is threadedly connected to the sliding plate. The transverse lead screw is rotatably connected to the main crossbeam. The sliding plate is fastened to the lifting mechanism and the balancing mechanism.

[0012] Two sets of columns are symmetrically placed on both sides of the worktable and fixed above the base. A main crossbeam is fixed in the middle of the two sets of columns. The balancing mechanism above the main crossbeam is used to balance the center of gravity of the lifting mechanism and the cutting assembly. Two sets of transverse slide rails are placed on the main crossbeam near the lifting mechanism. The transverse motor is placed in the middle of the two sets of transverse slide rails. The output torque of the transverse motor drives the transverse lead screw to rotate. Through the threaded connection between the transverse lead screw and the sliding plate, the sliding plate can move with the rotation of the transverse lead screw. Since the top of the sliding plate is connected to the balancing mechanism, most of the weight of the sliding plate is on the balancing mechanism, while the transverse slide rail only plays a guiding role.

[0013] Furthermore, the lifting mechanism includes a lifting plate, a lifting motor, lifting slide rails, and a lifting screw. There are two sets of lifting slide rails, which are symmetrically arranged on the sliding plate. The lifting motor is located between the two sets of lifting slide rails and is mounted on the sliding plate. The output end of the lifting motor is fastened to the lifting screw. The lifting screw passes through the lifting plate and is threadedly connected to the lifting plate. The lifting screw and the sliding plate are rotatably connected. A cutting component is provided on one side of the lifting plate.

[0014] Two sets of lifting slide rails are fixed to the sliding plate, and the lifting motor is placed in the middle of the two sets of lifting slide rails. The lifting motor outputs torque to drive the lifting screw to rotate. Through the threaded connection between the lifting screw and the lifting plate, the lifting plate can move with the rotation of the lifting screw. The cutting component is fixed to one side of the lifting plate. When the lifting plate moves up and down, the cutting component moves up and down at the same time, thereby cutting the workpiece up and down.

[0015] Furthermore, the cutting assembly includes a connecting frame and a cutting tool, the connecting frame and the lifting plate are fastened together, and the cutting tool is provided on the connecting frame.

[0016] The connecting frame is fixed to one side of the lifting plate and is used to connect the lifting plate and the cutting tool. The cutting tool is fixed on the connecting frame and is used to cut the workpiece.

[0017] Furthermore, the noise reduction mechanism includes a soundproof housing and a soundproof door. The soundproof housing is mounted on the machine tool, and the soundproof housing and the soundproof door are slidably connected.

[0018] The soundproof enclosure is fixed to the machine tool, serving two purposes: protecting the internal mechanism and blocking noise generated during operation. The soundproof door can slide on the enclosure; it is opened when workpieces need to be placed and closed when cutting is being performed.

[0019] Furthermore, the balancing mechanism includes a sliding component, a balancing beam, a counterweight, and a connecting block. The sliding component is located on the main beam near the sliding plate. The sliding component is fastened to the balancing beam, the balancing beam is fastened to the counterweight, the balancing beam is fastened to the connecting block, and the connecting block is fastened to the sliding plate.

[0020] The balance beam and main beam are connected by a sliding assembly. The balance beam and main beam are placed perpendicularly. The sliding assembly is not in the middle of the main beam, but rather located near the lifting mechanism. The lifting mechanism is located on one side of the main beam, while the counterweight is located on the other side. The upper end of the counterweight is directly connected to the balance beam. The balance beam is connected to the upper end of the sliding plate via a connecting block. Therefore, the sliding plate and balance beam slide synchronously on the main beam, and the counterweight slides along with the balance beam. The weight of the counterweight is approximately the same as the weight of the lifting mechanism and the cutting assembly, so the weights of the mechanisms on both sides of the main beam are roughly equal. Similarly, it will no longer twist to one side. Since the sliding component is not in the center of the balance beam, and the balance beam is similar to a lever structure, when the weight of the sliding plate at one end of the balance beam and the lifting mechanism on the sliding plate presses downward, there will be an upward tendency at the sliding component. However, since the balance beam is a rigid structure, the sliding component will provide an upward support force. The counterweight on the other side works on the same principle. This upward support force can also offset most of the torsional force in the main beam. At the same time, the upward support force can offset part of the weight of the balance mechanism, lifting mechanism and cutting component.

[0021] Furthermore, the sliding assembly includes a balance slide rail and a balance slider, the balance slide rail and two sets of balance sliders are slidably connected, the balance slide rail and the main crossbeam are fastened together, and the balance slider and the balance crossbeam are fastened together.

[0022] The balance rail is fixed to the main crossbeam, and the balance slider is fixed below the balance crossbeam. Through the connection between the balance crossbeam and the sliding plate, when the sliding plate moves, it drives the balance crossbeam to move, and at the same time drives the balance slider below to move. The two sets of balance sliders can provide stronger support.

[0023] Compared with the prior art, the beneficial effects of the present invention are: 1. In the present invention, the gravity of the lifting mechanism acts on one side of the main beam, while the balancing mechanism can provide a force opposite to the gravity, and the weight of the counterweight and the weight of the lifting mechanism are basically the same. The weights of the mechanisms on both sides of the main beam are roughly the same, and no torsional force to one side will be generated, so the two sides are balanced. 2. When the cutting component in this invention cuts the workpiece, if the workpiece has uneven hardness, it will generate periodic cutting impact force. The balancing mechanism uses the balancing component as a fulcrum to provide a reverse preload force to the main crossbeam, making it difficult for the cutting impact force to impact the main crossbeam. Furthermore, after the vibration generated during cutting is transmitted to the balancing mechanism, a large amount of vibration energy is consumed by the friction at the connection point, and the vibration energy is basically consumed, thereby reducing the noise of the entire device. 3. The noise reduction mechanism in this invention can isolate the entire device from the outside world, thereby reducing noise and preventing flying chips generated during cutting, thus protecting the operator.

[0027] Example: Figures 1-6 As shown, the present invention provides a technical solution for a gantry machining center with noise reduction function.

[0029] The noise reduction mechanism 6 is fixed on the support mechanism 1 to protect the entire device and block the sound emitted by the internal machinery, thereby achieving the effect of noise reduction. The workpiece to be processed is placed on the translation mechanism 2. The translation mechanism 2 can drive the workpiece above to move to different positions, thereby processing different positions on the workpiece. The cutting component 5 is fixed on one side of the lifting mechanism 4 for processing the workpiece. The lifting mechanism 4 can drive the cutting component 5 to move up and down, thereby cutting the workpiece up and down. The lifting mechanism 4 is fixed on the transverse mechanism 3. The balancing mechanism 7 is used to balance the center of gravity of the lifting mechanism 4.

[0030] like Figures 1-2 As shown, the support mechanism 1 includes a frame 11 and a machine tool 12. The machine tool 12 is mounted on the frame 11, and the machine tool 12 is mounted on the translation mechanism 2. The machine tool 12 and the noise reduction mechanism 6 are fastened together.

[0031] The frame 11 is used to support the entire device. The machine tool 12 is fixed above the frame 11. The machine tool 12 is used to determine the position of the translation mechanism 2. The noise reduction mechanism 6 is located above the machine tool 12 to shield other internal mechanisms and prevent noise from being transmitted.

[0032] like Figures 2-3 As shown, the translation mechanism 2 includes a worktable 21, a translation slide rail 22, a translation motor 23, a translation lead screw 24, and a base 25. There are two sets of translation slide rails 22, which are symmetrically arranged on the machine tool 12. The worktable 21 and the translation slide rails 22 are slidably connected. The translation motor 23 is fixed to one end of the machine tool 12 and is placed between the two sets of translation slide rails 22. The output end of the translation motor 23 is fastened to the translation lead screw 24. The translation lead screw 24 passes through the worktable 21 and is threadedly connected to the worktable 21. The translation lead screw 24 is rotatably connected to the base 25. The base 25 is provided with a transverse movement mechanism 3.

[0033] The base 25 is fixed above the machine tool 12. Two sets of translation slide rails 22 are fixed above the base 25. A translation motor 23 and a translation screw 24 are provided in the middle of the two sets of translation slide rails 22. The worktable 21 is installed above the base 25. The translation motor 23 outputs torque to drive the translation screw 24 to rotate. Through the threaded connection between the translation screw 24 and the worktable 21, the worktable 21 can move back and forth on the translation screw 24. The workpiece to be processed placed on the worktable 21 can move with the back and forth movement of the worktable 21, thereby processing different positions.

[0034] like Figure 4As shown, the transverse movement mechanism 3 includes a column 31, a main crossbeam 32, a transverse movement motor 33, a transverse movement slide rail 34, a transverse movement screw 35, and a sliding plate 36. There are two sets of columns 31, which are symmetrically arranged on the base 25. The main crossbeam 32 is located between the two sets of columns 31. The transverse movement motor 33 and the transverse movement slide rail 34 are located on one side of the main crossbeam 32. There are two sets of transverse movement slide rails 34, which are placed on both sides of the transverse movement motor 33. The transverse movement slide rail 34 and the sliding plate 36 are slidably connected. The output end of the transverse movement motor 33 is fastened to the transverse movement screw 35. The transverse movement screw 35 passes through the sliding plate 36. The transverse movement screw 35 and the sliding plate 36 are threadedly connected. The transverse movement screw 35 and the main crossbeam 32 are rotatably connected. The lifting screw 44 and the sliding plate 36 are rotatably connected. The sliding plate 36 and the lifting mechanism 4 are fastened to each other. The sliding plate 36 and the balancing mechanism 7 are fastened to each other.

[0035] Two sets of columns 31 are symmetrically placed on both sides of the workbench 21, and the columns 31 are fixed above the base 25. A main crossbeam 32 is fixed in the middle of the two sets of columns 31. The balancing mechanism 7 above the main crossbeam 32 is used to balance the center of gravity of the lifting mechanism 4 and the cutting assembly 5. Two sets of transverse slide rails 34 are placed on the main crossbeam 32 near the lifting mechanism 4. The transverse motor 33 is placed in the middle of the two sets of transverse slide rails 34. The output torque of the transverse motor 33 drives the transverse lead screw 35 to rotate. Through the threaded connection between the transverse lead screw 35 and the sliding plate 36, the sliding plate 36 can move with the rotation of the transverse lead screw 35. Since the top of the sliding plate 36 is connected to the balancing mechanism 7, most of the weight of the sliding plate 36 is on the balancing mechanism 7, while the transverse slide rail 34 only plays a guiding role.

[0036] like Figure 6 As shown, the lifting mechanism 4 includes a lifting plate 41, a lifting motor 42, a lifting slide rail 43, and a lifting screw 44. There are two sets of lifting slide rails 43, which are symmetrically arranged on the sliding plate 36. The lifting motor 42 is placed between the two sets of lifting slide rails 43 and is located on the sliding plate 36. The output end of the lifting motor 42 is fastened to the lifting screw 44. The lifting screw 44 passes through the lifting plate 41 and is threadedly connected to the lifting plate 41. A cutting assembly 5 is provided on one side of the lifting plate 41.

[0037] Two sets of lifting slide rails 43 are fixed on the sliding plate 36. The lifting motor 42 is placed in the middle of the two sets of lifting slide rails 43. The lifting motor 42 outputs torque to drive the lifting screw 44 to rotate. Through the threaded connection between the lifting screw 44 and the lifting plate 41, the lifting plate 41 can move with the rotation of the lifting screw 44. The cutting component 5 is fixed on one side of the lifting plate 41. When the lifting plate 41 moves up and down, the cutting component 5 moves up and down at the same time, thereby cutting the workpiece up and down.

[0038] like Figure 6As shown, the cutting assembly 5 includes a connecting frame 51 and a cutting tool 52. The connecting frame 51 and the lifting plate 41 are fastened together, and the cutting tool 52 is provided on the connecting frame 51.

[0039] The connecting frame 51 is fixed to one side of the lifting plate 41 and is used to connect the lifting plate 41 and the cutting tool 52. The cutting tool 52 is fixed on the connecting frame 51 and is used to cut the workpiece.

[0040] like Figures 1-5 As shown, the noise reduction mechanism 6 includes a soundproof housing 61 and a soundproof door 62. The soundproof housing 61 is mounted on the machine tool 12, and the soundproof housing 61 and the soundproof door 62 are slidably connected.

[0041] The soundproof housing 61 is fixed to the machine tool 12. On the one hand, it protects the internal mechanism, and on the other hand, it can block the noise generated when the internal mechanism is working. The soundproof door 62 can slide on the soundproof housing 61. When it is necessary to place the workpiece, the soundproof door 62 is opened, and when cutting is performed, the soundproof door 62 is closed.

[0042] like Figures 4-5 As shown, the balancing mechanism 7 includes a sliding component 71, a balancing beam 72, a counterweight 73, and a connecting block 74. The sliding component 71 is located on the main beam 32 on the side near the sliding plate 36. The sliding component 71 and the balancing beam 72 are fastened together. The balancing beam 72 and the counterweight 73 are fastened together. The balancing beam 72 and the connecting block 74 are fastened together. The connecting block 74 and the sliding plate 36 are fastened together.

[0043] The balance beam 72 and the main beam 32 are connected by a sliding assembly 71. The balance beam 72 and the main beam 32 are placed vertically. The sliding assembly 71 is not in the middle of the main beam 32, but is located near the lifting mechanism 4. The lifting mechanism 4 is located on one side of the main beam 32, and the counterweight 73 is located on the other side of the main beam 32. The upper end of the counterweight 73 is directly connected to the balance beam 72. The balance beam 72 is connected to the upper end of the sliding plate 36 through a connecting block 74. Therefore, the sliding plate 36 and the balance beam 72 slide synchronously on the main beam 32, and the counterweight 73 slides along with the balance beam 72. The weight of the counterweight 73 is basically the same as the weight of the lifting mechanism 4 and the cutting assembly 5, so the main beam 32... 2. The weights of the mechanisms on both sides are roughly the same, so they will not twist to one side. Since the sliding component 71 is not at the center of the balance beam 72, and the balance beam 72 is similar to a lever structure, when the weight of the sliding plate 36 at one end of the balance beam 72 and the lifting mechanism 4 on the sliding plate 36 presses downward, there will be an upward tendency at the sliding component 71. However, since the balance beam 72 is a rigid structure, the sliding component 71 will provide an upward support force. The counterweight 73 on the other side works on the same principle. This upward support force can also offset most of the torsional force in the main beam 32. At the same time, the upward support force can offset part of the weight of the balance mechanism 7, the lifting mechanism 4 and the cutting component 5.

[0044] like Figure 5 As shown, the sliding assembly 71 includes a balance slide rail 711 and a balance slider 712. The balance slide rail 711 and two sets of balance sliders 712 are slidably connected. The balance slide rail 711 is fastened to the main crossbeam 32, and the balance slider 712 is fastened to the balance crossbeam 72.

[0045] The balance slide rail 711 is fixed on the main crossbeam 32, and the balance slider 712 is fixed below the balance crossbeam 72. Through the connection between the balance crossbeam 72 and the sliding plate 36, when the sliding plate 36 moves, it drives the balance crossbeam 72 to move, and at the same time drives the balance slider 712 below to move. The two sets of balance sliders 712 can provide stronger support.

[0046] Working principle of the invention: The workpiece to be processed is placed on the worktable 21 and can move back and forth with it. The transverse mechanism 3 and the lifting mechanism 4 can control the transverse and vertical movement of the cutting assembly 5, allowing the cutting tool 52 to reach any position on the workpiece surface for processing. Since the lifting mechanism 4 is located on one side of the main crossbeam 32, its gravity acts on one side of the main crossbeam 32. Therefore, the balancing mechanism 7 on the main crossbeam 32 can balance the gravity biased to one side. The lifting mechanism 4 moves with the sliding plate 36, and the sliding plate 36 and the balancing crossbeam 72 move synchronously on the main crossbeam 32. The counterweight 73 slides along with the balancing crossbeam 72. The weight of the counterweight 73 is basically the same as the weight of the lifting mechanism 4 and the cutting assembly 5. The weights of the mechanisms on both sides of the main beam 32 are roughly the same, so they will not twist to one side. Since the sliding component 71 is not at the center of the balance beam 72, and the balance beam 72 is similar to a lever structure, when the weight of the sliding plate 36 at one end of the balance beam 72 and the lifting mechanism 4 on the sliding plate 36 presses downward, there will be an upward tendency at the sliding component 71. However, since the balance beam 72 is a rigid structure, the sliding component 71 will provide an upward support force. The counterweight 73 on the other side works on the same principle. This upward support force can also offset most of the torsional force in the main beam 32. At the same time, the upward support force can offset part of the weight of the balance mechanism 7, the lifting mechanism 4 and the cutting component 5.

[0047] 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. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
