Description

Technical Field

[0001] This application relates to the field of machining technology, and in particular to an angle adjustment structure for a machine tool coolant nozzle. Background Technology

[0002] In existing machine tool cooling systems, the coolant nozzle angle adjustment mechanism typically employs a drive motor directly mounted on a sliding block to move or deflect the nozzle. However, this design results in a large overall mass and high inertia for the sliding block and nozzle assembly, causing slow response when the nozzle needs to frequently change its spray position and angle, making it difficult to keep up with the pace of rapid machining. Furthermore, the movement and deflection actions often require two independent drive units, which are complex and space-consuming, further limiting the sensitivity and speed of adjustment. Summary of the Invention

[0003] This application aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes an angle adjustment structure for machine tool coolant nozzles, which can quickly adjust the angle and position of the coolant nozzles.

[0004] An angle adjustment structure for a machine tool coolant nozzle according to a first aspect of this application includes: a base, a column, a mounting beam, a sliding seat, and a third drive device. A turntable is rotatably mounted on the base, the turntable being used to support and fix the workpiece. The base is connected to a first driving device, which drives the turntable to rotate. A column is vertically connected to the base. A mounting beam is rotatably mounted on the column, the mounting beam having a first position and a second position. When the mounting beam is in the first position, it extends horizontally above the turntable; when the mounting beam is in the second position, it avoids the space above the turntable. A second driving device is provided on the column, which drives the mounting beam to switch between the first and second positions. A sliding seat is slidably mounted on the mounting beam, the sliding seat being movable along the length direction of the mounting beam. A nozzle mounting seat is rotatably mounted on the sliding seat, the rotation axis of the nozzle mounting seat being parallel to the length direction of the mounting beam, and a cooling nozzle is mounted on the nozzle mounting seat. A third driving device is connected to the mounting beam, the third driving device being used to drive the sliding seat to move and control the rotation angle of the nozzle mounting seat.

[0022] Reference Figures 1 to 9 As shown, an embodiment of this application discloses a machine tool coolant nozzle angle adjustment structure, comprising: a base 100, a column 200, a mounting beam 300, a sliding seat 500, and a third drive device 600. A turntable 110 is rotatably mounted on the base 100. The turntable 110 is horizontally positioned and has grippers that can clamp workpieces. The turntable 110 supports and fixes the workpiece, which is disc-shaped. A first drive device 120, a motor, is connected to the workpiece base 100. The output shaft of the first drive device 120 is fixedly connected to the turntable 110, driving the turntable 110 to rotate. The workpiece is rotated by the turntable 110 to facilitate turning or grinding processes. The column 200 is welded to the base 100 and is vertically positioned. The mounting beam 300 is rotatably mounted on the column 200, and its rotation axis extends horizontally. The mounting beam 300 has a first position and a second position. When the mounting beam 300 is in the first position, it extends horizontally above the turntable 110. When the mounting beam 300 is in the second position, it avoids the space above the turntable 110 to facilitate the hoisting of large or heavy workpieces. A second drive device 400 is installed on the column 200, which drives the mounting beam 300 to switch between a first position and a second position. A sliding seat 500 is slidably mounted on the mounting beam 300 and can move along the length of the mounting beam 300. A nozzle mounting seat 510 is rotatably mounted on the sliding seat 500, and the axis of rotation of the nozzle mounting seat 510 is parallel to the length of the mounting beam 300. A cooling nozzle 520 is mounted on the nozzle mounting seat 510. The direction in which the cooling nozzle 520 sprays coolant is perpendicular to the axis of rotation of the nozzle mounting seat 510. A third drive device 600 is connected to the mounting beam 300 and is used to drive the sliding seat 500 and control the rotation angle of the nozzle mounting seat 510. The cooling nozzle 520 moves and deflects with the nozzle mounting seat 510, so that the workpiece receives uniform coolant coverage during processing. The third drive device 600 can simultaneously control the movement and deflection angle of the cooling nozzle 520, saving equipment volume. There is no need to install a drive motor on the slide seat 500, and no need to set up separate drive units for the two actions, which effectively reduces the overall size of the equipment, reduces the weight and inertia of the moving parts, and enables the slide seat 500 to move and respond at a faster speed, improving the flexibility of the cooling nozzle 520 adjustment.

[0023] Reference Figures 5 to 8As shown, in some embodiments, the third driving device 600 includes a first driving member 610, which is a stepper motor. The first driving member 610 is bolted to the mounting beam 300. A first clamping plate 601 is connected to the first driving member 610, and the first clamping plate 601 is connected to the sliding seat 500. The first driving member 610 is used to drive the first clamping plate 601 to move along the length direction of the mounting beam 300. The linear motion of the driving member is transmitted to the sliding seat 500 through the first clamping plate 601, so that the sliding seat 500 itself does not need to be equipped with a drive motor, resulting in lighter weight and lower inertia.

[0024] Reference Figures 5 to 8 As shown, in some embodiments, a first synchronous pulley 602 and a second synchronous pulley 603 are rotatably mounted inside the mounting beam 300. A first synchronous belt 604 is wound around the first synchronous pulley 602 and the second synchronous pulley 603. The output shaft of the first drive member 610 is connected to the first synchronous pulley 602, and the first synchronous pulley 602 is bolted to the output shaft of the first drive member 610. The first synchronous belt 604 extends along the length of the mounting beam 300, and a first clamping plate 601 is bolted to the first synchronous belt 604. There is no relative slippage between the synchronous belt and the synchronous pulleys, which ensures a precise transmission ratio and accurately controls the linear position of the cooling nozzle 520. The synchronous belt is installed inside the mounting beam 300, which can effectively isolate external coolant and contaminants such as chips, reducing wear and corrosion. The mounting beam 300 is a square steel tube, and the side wall of the mounting beam 300 has clearance holes for the first clamping plate 601 to pass through. Compared with the screw mechanism, the synchronous belt is less expensive for long-distance transmission and is easier to install and adjust.

[0025] Reference Figures 5 to 7As shown, in some embodiments, the third driving device 600 includes a second driving member 620, which is a stepper motor. The second driving member 620 is connected to a second clamping plate 621, and is used to drive the first clamping plate 601 to move along the length direction of the mounting beam 300. A first gear 530 and a second gear 540 that mesh with each other are rotatably mounted on the sliding seat 500. The first gear 530 and the second gear 540 are bevel gear pairs. The rotation axes of the first gear 530 and the second gear 540 are perpendicular to each other. The second gear 540 is connected to the nozzle mounting base 510 and can drive the nozzle mounting base 510 to rotate. The first gear 530 has a horizontally extending first extension plate 531 and a second extension plate 532 connected to its periphery. The first extension plate 531 is hinged to the first clamping plate 601, and the second extension plate 532 is hinged to the second clamping plate 621. When the first clamping plate 601 and the second clamping plate 621 move asynchronously, they can drive the nozzle mounting base 510 to rotate through the first gear 530 and the second gear 540. When the first clamping plate 601 and the second clamping plate 621 move synchronously, they can drive the sliding seat 500 to move along the length of the mounting beam 300. Through the first driving member 610 and the second driving member 620 on the mounting beam 300, two degrees of freedom of movement, translation and rotation, are realized. Neither of the two movements requires a drive motor to be installed on the sliding seat 500, resulting in a compact structure and small size. When the first clamping plate 601 and the second clamping plate 621 move in the same direction and at the same speed, the first gear 530 translates but does not rotate, driving the sliding seat 500 to move linearly, while the nozzle mounting seat 510 does not deflect. When the first clamping plate 601 and the second clamping plate 621 move at different speeds or in different directions, the first gear 530 rotates, driving the second gear 540 and the nozzle mounting seat 510 to deflect via the bevel gear pair. By controlling the first driving member 610 and the second driving member 620, the cooling nozzle 520 can also be made to translate and deflect simultaneously, achieving changes in the coolant spray angle along arbitrary trajectories to adapt to complex curved surface machining. By changing the gear ratio of the first gear 530 and the second gear 540, the deflection angle range and resolution of the cooling nozzle 520 can be adjusted. The first extension plate 531 and the second extension plate 532 are symmetrically arranged with the first gear 530 as the center.

[0026] Reference Figures 5 to 9As shown, in some embodiments, a third synchronous pulley 605 and a fourth synchronous pulley 606 are rotatably mounted on the mounting beam 300. A second synchronous belt 607 is wound around the third synchronous pulley 605 and the fourth synchronous pulley 606. The output shaft of the second drive member 620 is connected to the third synchronous pulley 605. The second synchronous belt 607 extends along the length of the mounting beam 300, and a second clamping plate 621 is connected to the second synchronous belt 607. Using synchronous belt drive eliminates relative slippage, thereby achieving precise control. The first synchronous belt 604 and the second synchronous belt 607 are symmetrically installed within the mounting beam 300. The second drive member 620 and the first drive member 610 respectively control the first synchronous belt 604 and the second synchronous belt 607, enabling the first clamping plate 601 and the second clamping plate 621 to move independently. By controlling the speed difference or direction difference between their movements, the first gear 530 can be driven to rotate and translate, thereby causing the nozzle mounting seat 510 to deflect, achieving decoupling and compound control of movement and rotation.

[0027] Reference Figures 6 to 9 As shown, in some embodiments, the first extension plate 531 has a first slot 533, and the second extension plate 532 has a second slot 534. Both the first slot 533 and the second slot 534 extend radially along the first gear 530. A first screw 700 is threadedly connected to the lower end of the first clamping plate 601, and the first screw 700 is located at the end of the first clamping plate 601 away from the first synchronous belt 604. The first screw 700 passes through the first slot 533. A second screw 710 is threadedly connected to the lower end of the second clamping plate 621, and the second screw 710 passes through the second slot 534. When the first gear 530 is rotated by differential drive, the radial distance between the connection point on the first extension plate 531 and the second extension plate 532 and the center of the first gear 530 will change. The first slot 533 allows the first screw 700 to slide radially within the first slot 533, automatically compensating for radial displacement and thus avoiding interference. The function and role of the second slot 534 are the same as those of the first slot 533. The first screw 700 passes directly through the first slot 533. The structure is simple, reduces the number of parts, and facilitates disassembly, assembly, and adjustment.

[0028] Reference Figure 7 and Figure 8 As shown, in some embodiments, a bearing seat 800 is connected to the sliding seat 500, and a driven shaft 810 is rotatably mounted on the bearing seat 800. A second gear 540 and a nozzle mounting seat 510 are respectively fixedly connected to both ends of the driven shaft 810. Both ends of the driven shaft 810 are D-shaped shafts, and both the second gear 540 and the nozzle mounting seat 510 are connected to the driven shaft 810 by set screws. The combination of D-shaped shafts and set screws is common and results in low equipment cost. The sliding seat 500 is slidably mounted on the mounting beam 300 via a common linear guide rail.

[0029] Reference Figure 7and Figure 8 As shown, in some embodiments, the upper end of the cooling nozzle 520 is provided with a connecting portion 521 for connecting a flexible hose. The connecting portion 521 is a pagoda connector commonly used for connecting flexible hoses. The pagoda connector has multiple levels of annular protrusions, which can fit tightly against the inner wall of the hose. The lower end of the cooling nozzle 520 gradually narrows to form a coolant spray nozzle. The cross-sectional area of ​​the flow channel at the lower end of the cooling nozzle 520 gradually decreases, and the coolant flow velocity increases, thereby enhancing the impact force on the cutting area and effectively removing chips and heat. By controlling the narrowing angle and the shape of the coolant spray nozzle, different spray patterns can be achieved to adapt to various machining needs such as turning, milling, and grinding.

[0030] Reference Figures 1 to 4 As shown, in some embodiments, the lower end of the turntable 110 has an annular positioning groove 111, and the upper end of the base 100 has a positioning protrusion 101. The positioning protrusion 101 is embedded in the positioning groove 111, and the upper end of the positioning protrusion 101 is provided with a roller for reducing friction. The cooperation between the positioning protrusion 101 and the annular groove restricts the radial movement of the turntable 110, and the roller at the upper end of the positioning protrusion 101 provides rolling friction, reducing the resistance when the turntable 110 rotates.

[0031] Reference Figures 1 to 4 As shown, in some embodiments, the second drive device 400 is a hydraulic cylinder. The fixed end of the second drive device 400 is rotatably mounted on the column 200, and the telescopic end of the second drive device 400 is rotatably mounted on the mounting beam 300. The hydraulic cylinder can generate a large thrust in a small volume to drive the mounting beam 300 to rotate. The hydraulic system can utilize the sealing resistance inside the hydraulic cylinder or an external hydraulic lock to maintain pressure after the mounting beam 300 reaches the designated position, so that the mounting beam 300 can be stably maintained in the first position and the second position.

[0032] Operating steps: The first drive device 120 on the base 100 drives the turntable 110 to rotate, and the turntable 110 fixes the disc-shaped workpiece with its grippers. A swingable mounting beam 300 is installed on the column 200. The second drive device 400 drives the mounting beam 300 to switch between a first position and a second position to facilitate workpiece hoisting. The third drive device 600 includes a first drive component 610 and a second drive component 620, which drive the first clamping plate 601 and the second clamping plate 621 to move along the length of the mounting beam 300 via a first synchronous belt 604 and a second synchronous belt 607 built into the mounting beam 300, respectively. A bevel gear pair is provided in the sliding seat 500. The first gear 530 connects the first extension plate 531 and the second extension plate 532, and is hinged to the first clamping plate 601 and the second clamping plate 621, respectively; the second gear 540 connects the nozzle mounting seat 510 and the cooling nozzle 520. When the first clamping plate 601 and the second clamping plate 621 move synchronously, the sliding seat 500 moves as a whole, and the cooling nozzle 520 does not deflect. When the first clamping plate 601 and the second clamping plate 621 move at different speeds, the first gear 530 rotates and drives the cooling nozzle 520 to deflect through the second gear 540. This structure allows the cooling nozzle 520 to move along the mounting beam 300 and adjust the spray angle. The coolant is connected to the pagoda connector at the top of the cooling nozzle 520 via a hose and sprayed from the narrowed coolant nozzle into the processing area.

[0033] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
