Description

Technical Field

[0001] This invention relates to the field of vertical machining center technology, specifically to an interactive worktable vertical machining center. Background Technology

[0002] A vertical machining center is a machining center whose spindle axis is set perpendicular to the worktable. It is mainly suitable for machining complex parts such as plates, discs, molds, and small shells. Vertical machining centers can complete milling, boring, drilling, tapping, and thread cutting. Vertical machining centers have at least three axes with two linkages, and generally can achieve three axes with three linkages. Some can even perform five-axis or six-axis control. Vertical machining centers are convenient for workpiece clamping and positioning, the tool movement trajectory is easy to observe, and program debugging, inspection, and measurement are convenient. Problems can be detected in time, and machine stoppages or modifications can be made. Cooling conditions are easy to establish, and cutting fluid can directly reach the tool and the machined surface. The three coordinate axes are consistent with the Cartesian coordinate system, providing a visually intuitive experience consistent with the drawing perspective. Chips are easily removed and fall off, avoiding scratches on the machined surface.

[0003] For example, the Chinese authorized patent CN205571925U, entitled "A Vertical Machining Center with Dual Worktables and Moving Columns," includes a machine body, a protective cover covering the machine body, a drive system, and a control system. The machine body is horizontally arranged along the bottom of the machine body, and two worktable bases driven by a Y-axis drive system are slidably connected side by side in the middle of the machine body. Each worktable base is connected to a worktable. A machine tool wall is set across the two worktable bases at the rear end of the machine body. A cross slide driven by an X-axis drive system is set on the top surface of the machine tool wall, and a slide spindle driven by a Z-axis drive system is set on the front side of the cross slide. The tool magazine is set on one side of the machine tool wall.

[0004] While the aforementioned existing technologies add an extra worktable, improving the machine tool's response and speed, and completely solving the problem of machine tool stopping during loading and unloading, the interchangeability of the two worktables is highly demanding, significantly increasing the machining accuracy of parts and the assembly requirements for workers. This necessitates numerous complex components to achieve the worktable interchangeability function, resulting in an overly complex structure. Furthermore, vertical machining centers generate a large amount of waste during machining, which falls onto the worktable. Smaller pieces can easily get stuck in the gaps between the worktables, making cleaning inconvenient for workers. Therefore, these technologies do not meet current needs. To address this, we propose an interactive worktable vertical machining center. Summary of the Invention

The protrusion and the L-shaped block are slidably engaged with the transmission cavity and the upper gap of the double worktable.

[0009] Preferably, the driving mechanism includes a hydraulic cylinder fixedly mounted on the mounting platform, a mounting base fixedly mounted on the upper end of the hydraulic cylinder, and rollers rotatably mounted on both ends of the mounting base, with the rollers in contact with the double worktables, and the rotation direction of the rollers being tangential to the rotation direction of the double worktables.

[0010] Preferably, limit blocks are fixedly provided on both sides of the cylinder, and the two limit blocks are located in a straight line with the rotating shaft. The limit blocks are L-shaped, and the lower ends of the limit blocks abut against the lower ends of the mounting base.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention features a drive mechanism on the upper part of the mounting platform. During use, one end of the dual worktables is used to process workpieces, while the other end can be used simultaneously to assemble and disassemble parts to be processed. After processing, the drive mechanism lifts the dual worktables. The rotating shaft is movably mounted on the reducer via a splined shaft. The dual worktables drive the rotating shaft and the upper gear plate to move upwards, disengaging the upper gear plate from the lower gear plate. After the dual worktables rotate via a motor, the drive mechanism resets downwards, and the upper gear plate re-engages with the lower gear plate to lock the dual worktables. The overall structure is simple and practical, making daily use more convenient.

[0020] 2. This invention features transmission cavities on both sides of the double worktable. When processing debris enters the gap, the operator can rotate a knob, which drives the first threaded rod to rotate. Under the transmission of the bevel gear and the transmission belt, the second threaded rod rotates synchronously. The rotation of the first threaded rod causes the protrusion to move horizontally, and the rotation of the second threaded rod causes the L-shaped block to move horizontally as well. The simultaneous movement of the protrusion and the L-shaped block within the gap facilitates the movement of debris, making cleaning quick and easier.

[0021] 3. This invention uses noise reduction boxes fixed to both sides of the machining center body with screws. When the machining center body is working, it generates noise. Some of the noise is absorbed by the sound insulation board, and the remaining part enters the sound absorption cavity through the sound transmission channel. The sound absorption cavity is equipped with sound-absorbing airbags, which can further absorb the remaining noise. This can effectively reduce the transmission of noise, reduce the noise pollution generated when the machining center body is working, provide a good working environment, and facilitate the daily use of the staff.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] Please see Figure 1-10 An embodiment of the present invention provides: an interactive workbench vertical machining center, including a machining center body 1, an installation platform 3 fixedly installed inside the machining center body 1, a double workbench 2 installed above the installation platform 3, and a synchronizer 20 installed on one side of the installation platform 3;

[0035] It also includes a motor 4, which is located below the mounting platform 3 and is used to drive the double worktable 2 to rotate. A reducer 5 is located above the motor 4, and a splined shaft 6 is located at the output end of the reducer 5. A rotating shaft 7 is fixedly located at the middle position inside the double worktable 2 and is sleeved on the outer circumference of the splined shaft 6. An upper gear plate 8 is fixedly located at the lower end of the double worktable 2, and a lower gear plate 9 is fixedly located at the upper end of the mounting platform 3. The lower gear plate 9 meshes with the upper gear plate 8. The upper gear plate 8 and the lower gear plate 9 surround the outer circumference of the rotating shaft 7. Several drive mechanisms 10 are arranged in a ring at equal intervals at the upper end of the mounting platform 3.

[0036] It also includes a transmission cavity 27, which is opened on both sides inside the double worktable 2. A first threaded rod 29 is provided at the middle position inside the transmission cavity 27. A first rotating rod 28 is welded to both ends of the first threaded rod 29. A protrusion 34 is threadedly connected to the outside of the first threaded rod 29. A second threaded rod 30 is provided on both the front and rear ends inside the transmission cavity 27. Two of the second threaded rods 30 are rotatably connected to the transmission cavity 27. A second rotating rod 31 is welded to both ends of the two second threaded rods 30 and one end of the other two second threaded rods 30. Two of the second rotating rods 31 are rotatably connected to the transmission cavity 27. An L-shaped block 36 is threadedly connected to the outside of the second threaded rod 30. The upper ends of the protrusion 34 and the L-shaped block 36 penetrate the transmission cavity 27 and extend into the interior of the upper gap of the double worktable 2. The protrusion 34 and the L-shaped block 36 are slidably engaged with the transmission cavity 27 and the upper gap of the double worktable 2.

[0037] In use, one end of the double worktable 2 is used to process the workpiece, and the other end can be used to disassemble and assemble the parts to be processed. After processing, the double worktable 2 is lifted by the drive mechanism 10. The rotating shaft 7 is movably mounted on the reducer 5 through the spline shaft 6. The double worktable 2 drives the rotating shaft 7 and the upper gear plate 8 to move upward. The upper gear plate 8 disengages from the lower gear plate 9. After the double worktable 2 is rotated by the motor 4, the drive mechanism 10 is reset downward. The upper gear plate 8 re-engages with the lower gear plate 9 to complete the locking of the double worktable 2. This solves the problems of high interchangeability requirements of existing worktables, increased processing accuracy of parts and assembly requirements of workers, the need for more complex parts to realize the function of worktable interchangeability, and overly complex structure.

[0038] Please see Figure 4 The drive mechanism 10 includes a hydraulic cylinder 11 fixedly mounted on the mounting platform 3. A mounting base 12 is fixedly mounted on the upper end of the hydraulic cylinder 11. Rollers 13 are rotatably mounted on both ends of the mounting base 12, and the rollers 13 are in contact with the double worktable 2. The rotation direction of the rollers 13 is tangential to the rotation direction of the double worktable 2. The rollers 13 can better cooperate with the rotation of the double worktable 2.

[0039] Please see Figure 4 Limiting blocks 14 are fixedly installed on both sides of the hydraulic cylinder 11, and both limiting blocks 14 are aligned with the rotating shaft 7. The limiting blocks 14 are L-shaped, and the lower ends of the limiting blocks 14 abut against the lower ends of the mounting base 12. The outer wall of the mounting base 12 is in contact with the inner wall of the limiting blocks 14, and the upper end face of the limiting blocks 14 is located above the mounting base 12. The limiting blocks 14 can support the double worktable 2 during normal use and prevent the double worktable 2 from contacting the roller 13 and rotating.

[0040] Please see Figure 3 and Figure 4A sleeve 15 is fixedly installed on the outer periphery of the rotating shaft 7, and one end of the sleeve 15 extends downward. Several inner bearings 16 are fixedly installed on the outer periphery of the sleeve 15. Several outer bearings 17 are fixedly installed on the inner wall of the mounting platform 3, and the outer bearings 17 are all adapted to the inner bearings 16. The outer bearings 17 are all sleeved on the outer periphery of the inner bearings 16.

[0041] Please see Figure 4 There are two inner bearings 16. A retaining ring 18 is fixedly installed at the middle position of the outer wall of the sleeve 15, and the retaining ring 18 is located between the two inner bearings 16. The retaining ring 18 increases the stability of the inner bearings 16.

[0042] Please see Figure 4 A limiting ring 19 is fixedly provided at the lower end of the sleeve 15, and the limiting ring 19 is located at the lower end of one of the inner bearings 16. The limiting ring 19 increases the stability of the inner bearing 16.

[0043] Please see Figure 2 , Figure 3 , Figure 5 , Figure 7 , Figure 9 and Figure 10 Both first rotating rods 28 extend to the outside of the transmission cavity 27, and both first rotating rods 28 are rotatably engaged with the double worktable 2. A knob 26 is installed at the end of each first rotating rod 28 located outside the transmission cavity 27. First limiting grooves 35 are provided at the front and rear of the first threaded rod 29, and the first limiting grooves 35 are slidably engaged with the protrusion 34. A second limiting groove 37 is provided on one side of the second threaded rod 30, and the second limiting groove 37 is slidably engaged with the L-shaped block 36. The knob 26 is designed to facilitate the rotation of the first threaded rod 29 by the operator. The first limiting grooves 35 and the second limiting grooves 37 can respectively limit the axial movement of the protrusion 34 and the L-shaped block 36, so that the rotation of the protrusion 34 and the L-shaped block 36 can be converted into horizontal linear movement, which can push out the waste chips in the gap at the upper end of the double worktable 2.

[0044] Please see Figure 9 and Figure 10 The outer walls of the two first rotating rods 28 and one end of the second rotating rod 31 located in front of and behind the first rotating rods 28 are all fixedly provided with bevel gears 32, and the bevel gears 32 are meshed with each other. The meshing connection of the bevel gears 32 realizes the synchronous rotation of the first threaded rod 29 and the four second threaded rods 30.

[0045] Please see Figure 5 The transmission cavity 27 is equipped with transmission belts 33 on both the front and rear sides, and the second rotating rod 31 is connected to the transmission belts 33. The transmission connection of the transmission belts 33 realizes the synchronous rotation of the second threaded rod 30.

[0046] Please see Figure 1 and Figure 6 The machining center body 1 has noise reduction boxes 21 on both sides. The inner side of each noise reduction box 21 is provided with a sound insulation board 22. The outer side of each sound insulation board 22 is provided with a sound absorption cavity 24. The inside of each sound absorption cavity 24 is provided with a sound absorption airbag 25. Several sound transmission channels 23 arranged in a rectangular array are provided between the sound insulation board 22 and the sound absorption cavity 24. The sound insulation board 22 and the sound absorption airbag 25 can absorb noise and improve the noise reduction effect.

[0047] Working Principle: During operation, after placing the part on the double worktable 2, the machining center body 1 is started for processing. One end of the double worktable 2 is used to process the workpiece, while the other end can be used simultaneously to assemble and disassemble the part to be processed. After processing is completed, the hydraulic cylinder 11 is activated, causing the mounting base 12 to lift the double worktable 2 using the rollers 13. At this time, the rotating shaft 7 moves upward synchronously. The splined shaft ensures the connection between the rotating shaft 7 and the reducer 5. As the double worktable 2 moves upward, it drives the upper gear plate 8 upward, disengaging it from the lower gear plate 9. At this point, the motor 4 is started, and the reducer 5 enables the rotating shaft 7 to drive the double worktable 2 to rotate synchronously. The rollers 13 ensure the stability of the double worktable 2. After rotation, the hydraulic cylinder 11 resets, and the double worktable 2 drives the rotating shaft 7 and the upper gear plate 8 to move downwards. The upper gear plate 8 re-engages with the lower gear plate 9, thus locking the double worktable 2. The overall structure is simple and practical, and easy to use in daily life. When it is necessary to clean the waste in the gap after processing, the operator can turn the knobs 26 on both sides. The knobs 26 will drive the first threaded rod 29 and another first rotating rod 28 to rotate synchronously through the first rotating rod 28. The other first rotating rod 28 can drive two of the second rotating rods 31 to rotate through the meshing transmission of the bevel gear 32, thereby causing two of the second threaded rods 30 to rotate synchronously, while the remaining two second rotating rods... Under the transmission connection of the transmission belt 33, rod 31 can cause the remaining two second threaded rods 30 to rotate synchronously, thereby achieving synchronous rotation of the first threaded rod 29 and the four second threaded rods 30. When the first threaded rod 29 rotates, it will drive the protrusion 34 to rotate synchronously. When the second threaded rods 30 rotate, they will drive the L-shaped block 36 to rotate synchronously. Since the protrusion 34 and the L-shaped block 36 are slidably engaged with the first limiting groove 35 and the second limiting groove 37 respectively, the rotation of the protrusion 34 and the L-shaped block 36 will be converted into horizontal linear movement, so that the protrusion 34 and the L-shaped block 36 can slide within the gap at the upper end of the double worktable 2. The stuck debris can be pushed out, making it easier to clean quickly and conveniently. When the main body 1 of the machining center is processing, the noise generated will first be absorbed by the sound insulation plates 22 inside the noise reduction boxes 21 on both sides. The remaining noise will be transmitted into the sound absorption cavity 24 through the sound transmission channel 23. The sound absorption airbags 25 inside the sound absorption cavity 24 can absorb the remaining noise, thereby achieving noise reduction. Furthermore, the noise will be consumed by the zigzag structure when it passes through the sound transmission channel 23, which can further improve the noise reduction effect, reduce the noise pollution generated by the main body 1 of the machining center during operation, provide a good working environment, and facilitate the daily use of the staff.

[0048] 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.
