Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum alloy casting, and particularly relates to an aluminum alloy casting manipulator. Background Art

[0002] Aluminum alloy casting is a process method in which pure aluminum or aluminum alloy ingots are prepared according to standard component ratios, and then heated manually to turn them into aluminum alloy liquid or molten state, and then the aluminum liquid or molten aluminum alloy is poured into the cavity through a professional mold or corresponding process, and cooled to form the required shaped aluminum parts.

[0003] At present, there are still a large number of aluminum alloy casting factories using manual operation for casting. Since the temperature of the aluminum liquid or molten aluminum alloy is relatively high, it is easy to cause harm to the operators. Therefore, a variety of devices for metal casting have been proposed in the prior art. For example, a casting manipulator proposed in the Chinese utility model patent with the publication number CN203599510U includes a single-arm crane, a connecting piece, an operating rod and a casting bucket. By adding a single-arm crane, the danger of manual casting is reduced.

[0004] However, the manipulator of this device is connected to the casting bucket through a hook, which makes the casting bucket prone to large-amplitude shaking. A relatively large force needs to be applied to the operating rod to tilt the casting bucket to pour out the aluminum liquid. Moreover, during the pouring process, the operator needs to continuously apply an external force to the operating rod to control the tilting angle of the casting bucket. This process consumes a large amount of physical strength of the operator and is difficult to control the operating force. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an aluminum alloy casting manipulator that is easy to control the tilting angle of the casting bucket, so as to solve the problems proposed in the above background art.

[0006] To achieve the above technical purpose, the technical solution of the utility model is as follows:

[0007] An aluminum alloy casting manipulator includes a transfer mechanism and a tilting mechanism. The tilting mechanism includes a base and a casting bucket for containing aluminum liquid. The bottom of the casting bucket is hinged to the base. A slider is hinged to the outer circumferential side wall of the casting bucket. The slider is threadedly connected through a screw rod. The bottom of the screw rod is fixedly connected with a first bevel gear. A motor is installed on the base. The output shaft of the motor is fixedly connected with a second bevel gear. The first bevel gear and the second bevel gear are meshed and matched. When the screw rod rotates, the slider moves along the axis of the screw rod and drives the casting bucket to rotate around its bottom hinge shaft.

[0008] As a further improvement, a boss is fixedly provided on the base. When the casting bucket is placed vertically, the outer bottom surface of the casting bucket is flush with the upper surface of the boss. The boss is used to support the casting bucket and prevent the casting bucket from tilting backward.

[0009] As a further improvement, the transfer mechanism includes a lifting frame and a frame body. The lifting frame is formed into a rectangle by connecting two horizontal side frames and two vertical side frames end to end. The lifting frame is vertically arranged. At both ends of the horizontal side frame at the bottom, there are fixed connecting insertion arms. The extending direction of the insertion arms is perpendicular to the plane of the rectangle. There are horizontal slots on the base, and the extending direction of the slots is parallel to the extending direction of the positive projection of the screw rod on the base. The insertion arms are in sliding fit with the slots.

[0010] As a further improvement, one end of a first support arm is hinged to the lifting frame, and the other end of the first support arm is hinged to the frame body. Above the first support arm, there is a second support arm with the same length in parallel. One end of the second support arm is hinged to the lifting frame, and the other end of the second support arm is hinged to the frame body.

[0011] As a further improvement, a hydraulic jack is hinged to the bottom of the frame body, and the piston rod of the hydraulic jack is hinged to the first support arm. The telescopic movement of the piston rod drives the first support arm to make a circular motion around its connection point with the frame body, thereby driving the lifting and lowering of the lifting frame.

[0012] As a further improvement, directional casters are installed at the front end of the bottom of the frame body, and universal casters with a braking function are installed at the rear end of the frame body, enabling the transfer mechanism to move flexibly while preventing the transfer mechanism from sliding arbitrarily.

[0013] Due to adopting the above technical solutions, the beneficial effects of the present invention are as follows:

[0014] An aluminum alloy casting manipulator provided by the present utility model, by hinging a slider on the side wall of the casting bucket, and the slider is threadedly connected to a screw rod. Due to the self-locking property of the threaded connection, when pouring aluminum liquid, the tilting angle of the casting bucket can be easily controlled; by setting a transfer mechanism, the casting bucket can be smoothly transported to the pouring station for pouring operations.

[0022] Such as Figures 1-4As shown in the figure, an aluminum alloy casting robotic arm includes a transfer mechanism 2 and a tilting mechanism 1. The tilting mechanism 1 includes a base 102 and a cylindrical casting bucket 101 for containing molten aluminum. The bottom of the casting bucket 101 is hinged to the base 102. A slider 103 is hinged to the outer circumferential side wall of the casting bucket 101. The slider 103 is threadedly connected through a screw rod 104. The bottom of the screw rod 104 is fixedly connected with a first bevel gear 105. A motor 107 is installed on the base 102. The output shaft 108 of the motor 107 is fixedly connected with a second bevel gear 106. The first bevel gear 105 meshes and cooperates with the second bevel gear 106. When the screw rod 104 rotates, the slider 103 moves along the axis of the screw rod 104 and drives the casting bucket 101 to rotate around its bottom hinge axis. After the screw rod 104 stops rotating, due to the self-locking function of the cooperation between the screw rod 104 and the slider 103, the casting bucket 101 can still maintain this angle and continue to pour molten aluminum outwards without falling back backwards.

[0023] In this embodiment, a boss 109 is fixedly provided on the base 102. When the casting bucket 101 is placed vertically, the outer bottom surface of the casting bucket 101 is flush with and in contact with the upper surface of the boss 109. The boss 109 is used to support the casting bucket 101 and prevent the casting bucket 101 from tilting backwards.

[0024] In this embodiment, the transfer mechanism 2 includes a lifting frame 201 and a frame body 205. The lifting frame 201 is formed by connecting two horizontal frames and two vertical frames end to end to form a rectangle. The lifting frame 201 is vertically arranged. At both ends of the horizontal frame at the bottom, insertion arms 202 are fixedly connected. The extending direction of the insertion arms 202 is perpendicular to the plane of the rectangle. A horizontal slot hole 1021 is provided on the base 102. The extending direction of the slot hole 1021 is parallel to the extending direction of the positive projection of the screw rod 104 on the base 102. The insertion arms 202 are slidably matched with the slot hole 1021.

[0025] In this embodiment, one end of a first support arm 203 is hinged to the lifting frame 201. The other end of the first support arm 203 is hinged to the frame body 205. A second support arm 204 with the same length is arranged in parallel above the first support arm 203. One end of the second support arm 204 is hinged to the lifting frame 201. The other end of the second support arm 204 is hinged to the frame body 205.

[0026] In this embodiment, a hydraulic jack 206 is hinged to the bottom of the frame body 205. The piston rod 207 of the hydraulic jack 206 is hinged to the first support arm 203. The telescopic movement of the piston rod 207 drives the first support arm 203 to make a circular motion around its hinge point with the frame body 205, thereby driving the lifting of the lifting frame 201. Since the first support arm 203 and the second support arm 204 are equal in length and parallel, the lifting frame 201 always maintains a vertical direction, while the insertion arms 202 and the base 102 always maintain a horizontal direction.

[0027] In this embodiment, a directional caster 208 is installed at the front end of the bottom of the frame body 205, and a universal caster 209 with a braking function is installed at the rear end of the frame body 205, enabling the transfer mechanism 2 to move flexibly while preventing the transfer mechanism 2 from sliding arbitrarily.

[0028] When this embodiment is in use, the operator pushes the transfer mechanism 2 to insert the insertion arm 202 into the slot hole 1021 of the base 102, and continuously repeats the operation of manually pressing the operating rod 210 of the hydraulic jack 206 to eject the piston rod 207. Driven by the piston rod 207, the first arm 203 rotates around its hinge point with the frame body 205. After the lifting frame 201 drives the base 102 off the ground, the operator pushes the transfer mechanism 2 to the casting operation station. After the power supply of the motor 107 is turned on, the motor 107 runs. Specifically, the operation of the motor 107 can be controlled by a hand-held controller to adjust the tilting angle of the casting bucket 101 forward. After the casting operation is completed, the casting bucket 101 is restored to its original position.

[0029] The specific embodiments of the present invention described above do not constitute a limitation to the protection scope of the present invention. Any other corresponding changes and deformations made according to the technical concept of the present invention shall be included in the protection scope of the claims of the present invention.
