Description

Technical Field

[0001] The present invention relates to the technical field of die-casting machines, and particularly to an automatic differential pressure casting material receiving device. Background Art

[0002] The casting process is a continuous process. The material receiving device can quickly receive the castings, enabling the casting machine to promptly carry out the next casting cycle; without an efficient material receiving device, it takes time to handle the castings after each casting, which will greatly reduce the working efficiency of the casting machine.

[0003] For example, the patent with the publication number CN212469695U discloses a material taking device for a die-casting machine, which includes a base. A machine shell is fixedly installed on the top of the base. A connecting seat is movably installed on the top of the machine shell. The bottom of the connecting seat is fixedly installed with two transmission plates extending into the machine shell. The bottom of the connecting seat is fixedly installed with a rotating motor located on the opposite side of the two transmission plates. Two rotating rods are movably installed inside the machine shell, located in front of and behind the rotating motor respectively and passing through the two transmission plates. A transverse movement motor is fixedly installed on the left side of the machine shell and is in transmission connection with the rear rotating rod.

[0004] For example, the patent with the publication number CN207464157U discloses a material taking device for a die-casting machine, which includes a die-casting machine body with a forming station, a material taking manipulator assembly arranged outside the die-casting machine body and capable of extending into the forming station to take workpieces, a transmission mechanism arranged on one side of the material taking manipulator assembly, and a collection tray arranged at the end of the transmission mechanism. The transmission mechanism includes a front bracket and a rear bracket with adjustable heights, and a conveyor belt assembly inclinedly arranged on the front bracket and the rear bracket. The front bracket is higher than the rear bracket. The material taking manipulator assembly is located behind the front bracket, and the collection tray is located in front of the rear bracket.

[0005] For the prior art in the above patents, firstly, after taking the casting from the die-casting machine, it is impossible to place the casting regularly, which easily causes wear of the casting. Secondly, if the operator does not take away the casting on the clamping jaw, the material receiving device cannot receive the next casting, making the material receiving work more cumbersome. Summary of the Invention

[0006] The purpose of the present invention is to provide an automatic differential pressure casting material receiving device to solve the deficiencies in the above prior art.

[0007] To achieve the above object, the present invention provides the following technical solution: An automatic differential pressure casting material receiving device, including a base, further including: a carrier plate, which is movably arranged on the base, and at least two fixing sleeves for fixing castings are fixedly connected thereto. Each fixing sleeve has a receiving station for receiving castings during its moving stroke relative to the base; a clamping jaw, which is movably arranged on the base, and has a material taking station for clamping the casting during its moving stroke relative to the base, and a material placing station facing the fixing sleeve at the receiving station; a first driving member, which is used to drive the clamping jaw to slide vertically relative to the base; a second driving member, which is used to drive the clamping jaw to rotate relative to the base; a first linkage assembly, which is arranged between the carrier plate and the clamping jaw. During the process of the clamping jaw switching from the material placing station to the material taking station, the first linkage assembly drives the fixing sleeve fixed with the casting on the carrier plate to rotate away from the receiving station and the next fixing sleeve rotates to the receiving station.

[0008] Further, the first driving member is a hydraulic cylinder. The hydraulic cylinder includes a cylinder barrel and a piston rod. The cylinder barrel is rotatably connected to the base, the piston rod is slidably connected to the cylinder barrel, and the clamping jaw is fixedly connected to the piston rod.

[0009] Further, the second driving member includes a first motor. The housing of the first motor is fixedly connected to the base, and the output shaft of the first motor is coaxially and fixedly connected to the cylinder barrel.

[0010] Further, it further includes a telescopic rod. The outer sleeve of the telescopic rod is rotatably connected to the base, the inner rod of the telescopic rod is slidably connected to the outer sleeve, and the inner rod is coaxially and fixedly connected to the carrier plate.

[0011] Further, the first linkage assembly includes: a first gear, which is fixedly connected to the cylinder barrel; a ratchet and pawl mechanism, which is arranged on the outer sleeve of the telescopic rod; a cross plate, which is slidably connected to the base, and a first tooth group and a second tooth group are arranged thereon. The first tooth group meshes with the first gear, and the second tooth group meshes with the ratchet of the ratchet and pawl mechanism.

[0012] Further, it further includes a reverse linkage assembly. The reverse linkage assembly includes: a first slider, which is slidably connected to the base, the first slider is rotatably connected to the piston rod of the hydraulic cylinder, and a first rack is fixedly connected to the first slider; a second slider, which is slidably connected to the base, the second slider is rotatably connected to the inner rod of the telescopic rod, and a second rack is fixedly connected to the second slider; a second gear, which is rotatably connected to the base, and both the first rack and the second rack mesh with the second gear.

[0013] Further, the jaw includes: a housing fixedly connected to the piston rod; a double-threaded lead screw rotatably connected inside the housing, with two double-threaded sections provided thereon; two clamping portions both slidably connected to the housing, and the two clamping portions are respectively threadedly connected to the bidirectional lead screw; and a drive motor for driving the double-threaded lead screw to rotate relative to the housing.

[0014] Further, there are a plurality of the fixing sleeves, and the fixing sleeves are distributed in a circumferential array relative to the bearing plate.

[0015] Compared with the prior art, for an automatic differential pressure casting material receiving device provided by the present invention, after placing the previous casting, the jaw is driven to slide vertically upward by the first driving member, and then the jaw is driven to rotate by the second driving member. During the process of the jaw switching from the feeding station to the material taking station, the bearing plate is driven to rotate by the first linkage assembly, and the next fixing sleeve rotates to the receiving station. During the process of the claw switching from the material taking station to the feeding station after taking the material, the bearing plate does not rotate and waits for the claw to place the clamped casting on the fixing sleeve at the receiving station.

[0016] On the one hand, this device can automatically complete the material taking of multiple die casting machines without the cooperation of workers for a period of time, thus facilitating the work of workers. On the other hand, after taking the materials in sequence, this device neatly arranges them, reducing the probability of wear and tear in the material taking work of the castings.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Please refer to Figures 1-6 , an automatic differential pressure casting material receiving device, including a base (this is prior art and not shown in the figure), further including a carrier plate 1, a claw 2, a first driving member 3, a second driving member 4, and a first linkage assembly 5. The carrier plate 1 is movably arranged (sliding and rotating. The carrier plate 1 is slidably connected to the base through the sliding connection of the inner rod 62 and the sleeve rod 61 of the telescopic rod 6, and then the carrier plate 1 is rotatably connected to the base through the rotation of the sleeve rod 61 and the base). Multiple fixed sleeves 11 for fixing the casting 101 are fixedly connected to the carrier plate 1. The fixed sleeves 11 are circumferentially arranged relative to the carrier plate 1. In the moving stroke of each fixed sleeve 11 relative to the base, there is a receiving station for receiving the casting 101; the claw 2 is movably arranged on the base. In the moving stroke of the claw 2 relative to the base, there is a material taking station for clamping the casting 101, and a material placing station facing the fixed sleeve 11 at the receiving station; the first driving member 3 is used to drive the claw 2 to slide vertically relative to the base; the second driving member 4 is used to drive the claw 2 to rotate relative to the base; the first linkage assembly 5 is arranged between the carrier plate 1 and the claw 2. When the claw 2 switches from the material placing station to the material taking station, the first linkage assembly 5 drives the fixed sleeve 11 fixed with the casting 101 on the carrier plate 1 to rotate away from the receiving station and the next fixed sleeve 11 to rotate to the receiving station; the first driving member 3 is a hydraulic cylinder, the hydraulic cylinder includes a cylinder barrel 31 and a piston rod 32, the cylinder barrel 31 is rotatably connected to the base, the piston rod 32 is slidably connected to the cylinder barrel 31, the claw 2 is fixedly connected to the piston rod 32, and the second driving member 4 includes a first motor. The housing of the first motor is fixedly connected to the base, and the output shaft of the first motor is coaxially fixedly connected to the cylinder barrel 31.

[0028] It further includes a telescopic rod 6. The sleeve rod 61 of the telescopic rod 6 is rotatably connected to the base. The inner rod 62 of the telescopic rod 6 is slidably connected to the sleeve rod 61. The inner rod 62 is coaxially and fixedly connected to the bearing plate 1. The first linkage assembly 5 includes a first gear 51, a ratchet and pawl mechanism 52 and a cross plate 53. The first gear 51 is fixedly connected to the cylinder barrel 31. The ratchet and pawl mechanism 52 is arranged on the sleeve rod 61 of the telescopic rod 6. The cross plate 53 is slidably connected to the base. A first tooth set 531 and a second tooth set 532 are arranged on the cross plate 53. The first tooth set 531 meshes with the first gear 51. The second tooth set 532 meshes with the ratchet of the ratchet and pawl mechanism 52. In the ratchet and pawl mechanism 52, the ratchet is rotatably connected to the base, the pawl is rotatably connected to the sleeve rod 61 of the telescopic rod 6, and an elastic member is arranged between the pawl and the telescopic rod 6.

[0029] After the clamping jaws clamp a casting 101 at the material taking station, the hydraulic cylinder is driven to rotate relative to the base by the first driving motor 24. When the hydraulic cylinder rotates relative to the base, it will drive the clamping jaws to move from the material taking station to the material placing station. In addition, the rotation of the hydraulic cylinder will drive the first gear 51 to rotate. Since the first gear 51 meshes with the first tooth set 531 on the cross plate 53, the rotation of the first gear 51 will drive the cross plate 53 to slide horizontally. During the horizontal sliding of the cross plate 53, the cross plate 53 will also drive the ratchet to rotate through the second tooth set 532 on the cross plate 53. The ratchet will drive the pawl to twist and then reset, but the sleeve rod 61 of the piston rod 32 does not rotate, and thus the bearing plate also remains stationary. After the clamping jaws rotate the casting 101 to the material placing station, the piston rod 32 of the hydraulic cylinder moves vertically downward so that the casting 101 can be clamped into the fixed sleeve 11 at the receiving station on the bearing plate. Then, the piston rod 32 of the hydraulic cylinder drives the clamping jaws to move vertically upward until it exceeds the height of the casting 101. The hydraulic cylinder is driven to rotate again by the first motor. The rotation of the hydraulic cylinder drives the cross plate 53 to move horizontally through the cooperation of the first gear 51 and the first tooth set 531 of the cross plate 53. During the horizontal movement of the cross plate 53, the ratchet is driven to rotate again through the second tooth set 532. The rotation of the ratchet will drive the telescopic rod 6 to rotate through the cooperation with the pawl, and thus the bearing plate 1 rotates. The rotation of the bearing plate 1 makes the next fixed sleeve 11 (without placing the casting 101) rotate to the receiving station. After the casting 101 is placed on multiple fixed sleeves 11, the worker can perform centralized collection and processing on the casting 101.

[0030] Compared with the prior art, an automatic differential pressure casting material receiving device provided by the present invention, after placing the previous casting 101, drives the clamping jaws to slide vertically upward through the first driving member 3, and then drives the clamping jaws to rotate through the second driving member 4. During the process of the clamping jaws switching from the material placing station to the material taking station, the first linkage assembly 5 drives the bearing plate 1 to rotate, and the next fixed sleeve 11 rotates to the receiving station. During the process of the clamping claws taking the material and switching from the material taking station to the material placing station, the bearing plate 1 does not rotate waiting for the clamping claws 2 to place the clamped casting 101 on the fixed sleeve 11 at the receiving station.

[0031] On the one hand, this device can automatically complete the material taking of multiple die casting machines in sequence without the need to cooperate with workers for a period of time, which facilitates the work of workers. On the other hand, after taking the materials in sequence, this device arranges them neatly, reducing the probability of wear and tear in the material taking work of the casting 101.

[0032] Among them, it further includes a reverse linkage assembly. The reverse linkage assembly includes a first slider 7, a second slider 8, and a second gear 9. The first slider 7 is slidably connected to the base. The first slider 7 is rotatably connected to the piston rod 32 of the hydraulic cylinder. A first rack 71 is fixedly connected to the first slider 7. The second slider 8 is slidably connected to the base. The second slider 8 is rotatably connected to the inner rod 62 of the telescopic rod 6. A second rack 81 is fixedly connected to the second slider 8. The second gear 9 is rotatably connected to the base. Both the first rack 71 and the second rack 81 are engaged with the second gear 9. When the clamping jaws place the casting 101 on the fixed sleeve 11 at the receiving station, at this time, the casting 101 affects the rotation of the clamping jaws. The piston rod 32 of the hydraulic cylinder is used to drive the clamping jaws to move vertically upward. During the movement of the piston rod 32, the piston rod 32 will drive the first slider 7 to move vertically synchronously. The first slider 7 moving vertically upward drives the first rack 71 to move vertically upward. During the movement of the first rack 71, it will drive the second gear 9 to rotate. The rotation of the second gear 9 can cause the second rack 81 to slide vertically downward. The sliding directions of the first rack 71 and the second rack 81 are opposite. While the second rack 81 moves vertically downward, it will also drive the second slider 8 to move vertically downward. The second slider 8 moving vertically downward will drive the inner rod 62 of the telescopic rod 6 to move downward. During the process of the clamping jaws moving vertically upward, the reverse linkage assembly is used to drive the casting 101 on the bearing plate 1 to move vertically downward, which can quickly prevent the casting 101 between the clamping jaws from affecting the rotation of the clamping jaws. In addition, the first slider 7 being rotatably connected to the piston rod 32 of the hydraulic cylinder enables the piston rod 32 to drive the first slider 7 to move vertically, and the first slider 7 does not affect the rotation of the piston rod 32 relative to the base. Similarly, the second slider 8 being rotatably connected to the inner rod 62 of the telescopic rod 6 enables the second slider 8 to drive the inner rod 62 to move vertically, and the second slider 8 does not affect the rotation of the inner rod 62 relative to the base.

[0033] Among them, the clamping jaws include a housing 21, a double-threaded lead screw 22, a driving motor 24 and two clamping parts 23. The housing 21 is fixedly connected to the piston rod 32. The double-threaded lead screw 22 is rotatably connected within the housing 21, and two double-threaded sections are provided on the double-threaded lead screw 22. Both clamping parts 23 are slidably connected to the housing 21, and the two clamping parts 23 are respectively threadedly connected to the bidirectional lead screw. The two clamping parts 23 are respectively threadedly connected to the two threaded sections of the double-threaded lead screw 22 in a one-to-one correspondence. By driving the double-threaded lead screw to rotate through the driving motor 24, since the two clamping parts 23 are slidably connected to the housing 21, when the double-threaded lead screw rotates, the two clamping parts 23 will be driven to move towards or away from each other. In addition, the driving motor 24 is a self-locking motor, and after the two clamping parts 23 clamp the casting 101, the clamping parts 23 can be kept stationary.

[0034] Only some exemplary embodiments of the present invention have been described above by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
