Description

Technical Field

[0001] This invention relates to the field of intelligent lathe technology, specifically to an intelligent integrated loading and unloading device for a dual-station vertical lathe. Background Technology

[0002] A boring and milling machine is an industrial machining equipment that integrates boring and milling functions. Its machining accuracy and surface quality are superior to ordinary drilling machines, making it particularly suitable for precision machining of large box-shaped parts. This equipment is widely used in industries such as energy, mold making, and shipbuilding.

[0003] Patent application number CN201811522249.3 discloses a double-sided boring and milling machine, including a base, a worktable, a slide, a column, and a spindle box; the worktable is slidably mounted above the base; the slide includes a left slide and a right slide; the column includes a left column and a right column; the spindle box includes a left spindle box and a right spindle box; the left and right slides are symmetrically fixedly mounted on two sides of the base in the width direction; the left and right columns are slidably mounted on the left and right slides respectively; the left and right spindle boxes are slidably mounted on the left and right columns respectively, and the left and right spindle boxes are arranged opposite to each other. The invention features a left and right spindle box positioned opposite each other, enabling double-sided boring and milling. It can simultaneously process holes and cavities of the same shape, resulting in high processing efficiency. It is particularly suitable for processing deep-hole parts or wide parts with coaxial holes on both sides. It can complete boring on both sides simultaneously with a single clamping, achieving high processing efficiency and high precision.

[0004] The current mainstream solution generally uses opposing boring and milling machines to process the same workpiece. When it is not necessary to process symmetrical double-sided boring and milling, the two machines cannot work separately, resulting in limited mechanical functions and waste of resources. At the same time, when processing large workpieces, it is not easy to transfer the workpiece to the worktable, and large workpieces are prone to slippage during boring and milling, resulting in reduced machining accuracy.

[0005] In view of this, we propose an intelligent integrated loading and unloading device for dual-station vertical lathes. Summary of the Invention

[0006] To overcome the deficiencies in the prior art, the present invention aims to provide an intelligent integrated loading and unloading device for a dual-station vertical lathe. This device utilizes interlocking worktables to accommodate collaborative or separate processing by two main machines. A support assembly moves the support platform up and down, bringing the workpiece to the same height as the worktable. An insert plate connects the support platform to the worktable. Two clamping arms in the clamping mechanism hold the workpiece, and a ball screw drives the clamping mechanism to move the workpiece to the worktable for processing, thus solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides an intelligent integrated loading and unloading device for a dual-station vertical lathe, comprising two main lathes placed opposite each other and their corresponding worktables, a sliding base installed at the bottom of the main lathes for driving their movement, feeding devices placed on both sides of the worktables for loading and unloading workpieces, and sliding support devices installed on both sides of the two feeding devices for clamping workpieces. The two worktables can move with the sliding bases to engage with each other.

[0008] The feeding device includes a base, a mounting plate that can move up and down on the top of the base, and two support pieces that can be slidably connected to the top of the mounting plate and can engage with each other. The top of the base is equipped with a support component for supporting the up and down movement of the mounting plate, and the mounting plate is equipped with an adjusting component for connecting the two support pieces and controlling their movement towards each other.

[0009] This feature allows the support components to move up and down, adjusting the support components to the same height as the worktable, thus facilitating the movement of workpieces from the support components onto the worktable. The adjustment mechanism allows the two support components to engage or disengage, ensuring that the support components correspond to the worktable.

[0010] The sliding device includes a stand fixed between two bases, a clamping component slidably connected to the stand for clamping the workpiece, and a ball screw installed inside the stand and connected to the clamping component; the clamping component includes a clamping seat slidably connected to the stand and two clamping arms slidably connected to the clamping seat that can slide relative to each other.

[0011] This setup uses two clamping arms to hold and fix the workpiece on both sides. The workpiece is moved to the worktable by moving the clamping parts via a ball screw. After the workpiece is processed, it is moved to the support piece on the other side.

[0012] As a further improvement to this technical solution, the support assembly includes cross arms disposed on both sides of the base, four connecting rods connecting the corresponding ends of the two cross arms, and an electric telescopic rod installed on the top of the base. Long strips are welded and fixed on both sides of the top surface of the base. The two ends of one of the connecting rods located below extend into the long strip holes opened on the two sides of the long strips respectively. The telescopic end of the electric telescopic rod is connected to the middle part of the connecting rod located at the bottom end extending into the long strip hole.

[0013] This feature allows the connecting rod to slide back and forth along the elongated hole via an electric telescopic rod, adjusting the opening and closing angle of the cross arm, thereby enabling the mounting plate to move up and down.

[0014] As a further improvement to this technical solution, the top surface of the mounting plate is provided with a sliding groove that matches the size of the support piece, and the center of the top surface of the base is provided with a mounting groove for installing the electric telescopic rod.

[0015] This feature allows the two support pieces to slide relative to each other along a groove, and the mounting groove facilitates the installation of the electric telescopic rod.

[0016] As a further improvement to this technical solution, the adjusting component includes a spur gear rotatably connected inside the mounting plate, two racks slidably connected inside the mounting plate, and an adjusting rod rotatably connected inside the mounting plate, wherein the spur gear meshes with both racks.

[0017] As a further improvement to this technical solution, the end of the rack away from the spur gear is welded and fixed to the bottom end of the support piece on the corresponding side. A first bevel gear is welded and fixed at the center of the bottom end of the spur gear, and a second bevel gear is welded and fixed at the end of the adjusting rod. The first bevel gear and the second bevel gear mesh with each other. A handle is welded and fixed at one end of the adjusting rod after it extends out of the mounting plate.

[0018] These two settings are achieved by rotating the adjustment lever, which in turn drives the second bevel gear to rotate. The first bevel gear then drives the sprocket to rotate, which in turn causes the two racks to slide relative to each other, thus allowing the two support components to slide towards each other.

[0019] As a further improvement to this technical solution, the support plate includes a support plate slidably connected to the top of the mounting plate and an insert plate slidably inserted into the top of the support plate. A threaded rod is rotatably connected inside the support plate, and a threaded hole adapted to the threaded rod is opened on the insert plate. A groove adapted to the size of the insert plate is opened on the top of the worktable.

[0020] This feature allows the insert plate to slide into a groove on the worktable by rotating the threaded rod, thus creating a connection between the support plate and the worktable.

[0021] As a further improvement to this technical solution, a first motor is installed on one side of the support plate, and the output shaft of the first motor is coaxially connected to the threaded rod. Several rollers are rotatably connected to the top of both the support plate and the insert plate.

[0022] In this configuration, the first motor provides power for the rotation of the threaded rod, and the rollers facilitate the movement of the workpiece between the support plate and the worktable.

[0023] As a further improvement to this technical solution, multiple sliding rods are welded and fixed between the two columns of the upright frame. A third motor is installed on one side of the upright frame. The output shaft of the third motor is coaxially connected to the ball screw. A through hole adapted to the sliding rod is provided on the clamping seat. An installation hole adapted to the ball screw is provided at the bottom of the clamping seat.

[0024] This setting provides power to the ball screw, which in turn drives the clamping seat to slide back and forth.

[0025] As a further improvement to this technical solution, an elliptical turntable is rotatably connected to the middle of the clamping seat, and hinge rods are hinged to both ends of the side of the elliptical turntable. The other end of the hinge rod is hinged to the corresponding clamping arm.

[0026] This feature involves rotating an elliptical turntable, which in turn moves two hinged rods along the turntable, causing the two clamping arms to slide towards each other to clamp the workpiece.

[0027] As a further improvement to this technical solution, a second motor is installed at the center of the back of the clamping seat. The second motor is coaxially connected to the elliptical turntable, and a soft rubber pad is adhered and fixed to the side wall of the clamping arm.

[0028] This feature includes a second motor that powers the rotation of the elliptical turntable, and soft rubber pads that increase friction between the clamping arms and the workpiece.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] 1. This intelligent integrated loading and unloading device for a dual-station vertical lathe uses a drive electric telescopic rod to slide the connecting rod, causing the angle of the cross arm to change, thus moving the mounting plate up and down. This adjusts the support plate and the worktable to the same height. The first motor is then started, driving the threaded rod to rotate, allowing the insert plate to be inserted into the worktable. The second motor is then started, driving the elliptical turntable to rotate, which in turn drives two clamping arms to hold the workpiece via a hinged rod. Finally, the third motor is started, moving the workpiece from the support plate to the worktable via a ball screw. This facilitates loading and unloading of the workpiece, while the clamping arms hold the workpiece firmly, preventing slippage during boring and milling operations and improving machining accuracy.

[0031] 2. The intelligent integrated loading and unloading device for this dual-station vertical lathe uses a sliding base to drive the two worktables to open and close, adapting to the collaborative processing or separate processing of two main lathes, increasing mechanical work and avoiding resource waste.

The two worktables 200 can move with the sliding base 300 to interlock with each other. The interlocking worktables 200 can be used for the two main lathes 100 to work together or work separately.

[0050] Please see Figure 3 and Figure 4 As shown, the feeding device 400 includes a base 410, a mounting plate 430 that is movable up and down and is mounted on the top of the base 410, and two support pieces 450 that are slidably connected to the top of the mounting plate 430 and can be engaged with each other. A support assembly 420 for supporting the up and down movement of the mounting plate 430 is mounted on the top of the base 410. An adjusting member 440 for connecting the two support pieces 450 and controlling their movement towards each other is installed inside the mounting plate 430. The support assembly 420 can move the support pieces 450 up and down and adjust the support pieces 450 to the same height as the worktable 200, so as to facilitate the movement of the workpiece on the support piece 450 to the worktable 200. The adjusting member 440 can control the two support pieces 450 to engage or disengage with each other so that the support pieces 450 correspond to the worktable 200.

[0051] Please see Figure 7 and Figure 8As shown, the sliding device 500 includes a stand 510 fixed between two bases 410, a clamping member 520 slidably connected to the stand 510 for clamping the workpiece, and a ball screw 530 installed in the stand 510 and connected to the clamping member 520. The clamping member 520 includes a clamping seat 521 slidably connected to the stand 510 and two clamping arms 526 slidably connected to the clamping seat 521 and slidably sliding relative to each other. The two clamping arms 526 clamp the workpiece on both sides and fix it. The workpiece is moved to the worktable 200 by moving the clamping member 520 through the ball screw 530. After the workpiece is processed, the workpiece is moved to the support member 450 on the other side.

[0052] For details, please refer to Figure 5 As shown, the adjusting member 440 includes a spur gear 441 rotatably connected inside the mounting plate 430, two racks 442 slidably connected inside the mounting plate 430, and an adjusting rod 445 rotatably connected inside the mounting plate 430. The spur gear 441 meshes with both racks 442, and the rotation of the spur gear 441 drives the two racks 442 to slide towards each other.

[0053] For further details, please refer to Figure 5 As shown, the end of the rack 442 away from the spur gear 441 is welded and fixed to the bottom end of the support piece 450 on the corresponding side. A first bevel gear 443 is welded and fixed at the center of the bottom end of the spur gear 441. A second bevel gear 444 is welded and fixed to the end of the adjusting rod 445. The first bevel gear 443 and the second bevel gear 444 mesh with each other. A handle is welded and fixed to one end of the adjusting rod 445 after it extends out of the mounting plate 430. By rotating the adjusting rod 445 through the handle, the second bevel gear 444 is driven to rotate, and the spur gear 441 is driven to rotate through the meshing first bevel gear 443.

[0054] For details, please refer to Figure 3 and Figure 4 As shown, the support assembly 420 includes cross arms 421 disposed on both sides of the base 410, four connecting rods 422 connecting the corresponding ends of the two cross arms 421, and an electric telescopic rod 423 installed on the top of the base 410. Long strips 411 are welded and fixed on both sides of the top surface of the base 410. The two ends of a connecting rod 422 located below extend into the long strip holes opened on the two side strips 411 respectively. The telescopic end of the electric telescopic rod 423 is connected to the middle of the connecting rod 422 located at the bottom end extending into the long strip hole. The electric telescopic rod 423 drives the connecting rod 422 to slide back and forth in the long strip hole, thereby changing the cross angle of the cross arms 421, and thus causing the mounting plate 430 to move up and down.

[0055] In addition, please see Figure 3 and Figure 4As shown, the top surface of the mounting plate 430 has a sliding groove that matches the size of the support piece 450, and the center of the top surface of the base 410 has a mounting groove 412 for mounting the electric telescopic rod 423. The sliding groove is used for the two support pieces 450 to slide back and forth.

[0056] For further details, please refer to Figure 7 and Figure 8 As shown, multiple sliding rods 511 are welded and fixed between the two columns of the upright frame 510. A third motor 540 is installed on one side of the upright frame 510. The output shaft of the third motor 540 is coaxially connected to the ball screw 530. The clamping seat 521 has through holes that are compatible with the sliding rods 511. The bottom end of the clamping seat 521 has mounting holes 522 that are compatible with the ball screw 530. The third motor 540 provides power for the ball screw 530 to work. The compatible through holes and sliding rods 511 allow the clamping seat 521 to slide back and forth along the sliding rods 511.

[0057] For details, please refer to Figure 8 As shown, an elliptical turntable 523 is rotatably connected to the middle of the clamping base 521. Both ends of the elliptical turntable 523 are hinged to hinge rods 524. The other end of the hinge rods 524 is hinged to the corresponding clamping arm 526. When the elliptical turntable 523 rotates, it causes the angle between the hinge rods 524 on both sides and the horizontal plane to change, thereby causing the two clamping arms 526 to slide towards each other.

[0058] It is worth noting that, please refer to Figure 8 As shown, a second motor 525 is installed at the center of the back of the clamping base 521. The second motor 525 is coaxially connected to the elliptical turntable 523. A soft rubber pad is adhered and fixed to the side wall of the clamping arm 526. The second motor 525 provides power for the rotation of the elliptical turntable 523, and the soft rubber pad increases the friction between the clamping arm 526 and the workpiece.

[0059] For further details, please refer to Figure 6 As shown, the support plate 450 includes a support plate 451 slidably connected to the top of the mounting plate 430 and an insert plate 452 slidably inserted into the top of the support plate 451. A threaded rod 453 is rotatably connected inside the support plate 451. A threaded hole adapted to the threaded rod 453 is opened on the insert plate 452. A groove adapted to the size of the insert plate 452 is opened at the top of the worktable 200. When the threaded rod 453 rotates, the insert plate 452 moves onto the worktable 200.

[0060] For details, please refer to Figure 6 As shown, a first motor 454 is installed on one side of the support plate 451. The output shaft of the first motor 454 is coaxially connected to the threaded rod 453. Several rollers 455 are rotatably connected to the top of both the support plate 451 and the insert plate 452. The first motor 454 provides power for the rotation of the threaded rod 453, and the rollers 455 facilitate the movement of the workpiece.

[0061] In operation, the intelligent integrated loading and unloading device for a dual-station vertical lathe of the present invention first places the workpiece on the support plate 451, drives the electric telescopic rod 423, and pushes the connecting rod 422 to slide along the elongated hole on the long strip block 411, thereby increasing the opening angle of the cross arm 421, which causes the mounting plate 430 to move upward, and thus brings the support plate 450 and the worktable 200 to the same height. Then, the first motor 454 is driven to rotate the threaded rod 453, causing the insert plate 452 to extend into the groove on the worktable 200. Next, the second motor 525 is driven to rotate the elliptical turntable 523, increasing the angle between the hinge rod 524 and the horizontal plane, thus allowing the two clamps to... Arm 526 clamps and fixes the workpiece, and then drives the third motor 540 to move the clamping member 520 through the ball screw 530, moving the workpiece onto the worktable 200. The main lathe 100 processes the workpiece. After processing, the workpiece is moved to the feeding device 400 on the other side for unloading. When the two main lathes 100 need to process together, the sliding base 300 is driven to move the two worktables 200 toward each other, so that the two worktables 200 are engaged with each other. Then, the adjusting rod 445 is rotated, and the second bevel gear 444 and the first bevel gear 443 drive the spur gear 441 to rotate, so that the two racks 442 move relative to each other, so that the two support members 450 are engaged with each other.

[0062] It should be noted that the above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
