Description

Technical Field

[0001] This utility model relates to the field of metal processing equipment technology, specifically to a rotary table for processing non-ferrous metal alloy castings. Background Technology

[0002] Non-ferrous metal alloys are alloys composed primarily of non-ferrous metals, with the addition of other elements. Compared to pure metals, non-ferrous metal alloys not only possess higher strength and hardness but also exhibit excellent mechanical properties and corrosion resistance. Due to their unique characteristics, non-ferrous metal alloys have become the preferred material for the development of shells in aerospace, aviation, and military products.

[0003] Existing non-ferrous metal alloy parts are typically formed by casting. After cooling and forming, the workpieces are usually transferred to a workbench for surface treatment. The existing workbench structure typically includes a work plate, a base fixedly connected to the bottom of the work plate, and grippers fixedly connected to the top of the work plate. In use, the base provides support for the work plate, and the grippers fixedly connected to the work plate hold the workpiece. After holding it, the worker uses a hand polishing tool to polish the surface of the workpiece.

[0004] The aforementioned prior art has the following drawbacks: When machining ring-shaped or near-ring-shaped castings, the circumferential side of the casting is arc-shaped, and the clamping method usually obstructs the circumferential side of the casting. As a result, the worker cannot directly complete the processing steps of the circumferential side of the ring-shaped or near-ring-shaped casting in one go. Therefore, it is necessary to release the fixation and re-clamp, which is cumbersome and affects efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a turntable for processing non-ferrous metal alloy castings, which reduces the area of ​​obstruction on the circumferential side of the casting when fixing ring-shaped or quasi-ring-shaped castings, thereby solving the problems mentioned in the background art.

[0006] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution: A rotary table for processing non-ferrous metal alloy castings includes a base, a work plate fixedly connected to the top of the base, a work groove on the work plate, an operating plate covering the work groove, a rotating assembly between the work plate and the operating plate for the operating plate to rotate above the work groove, a stop hole on the side of the operating plate near the rotating assembly, at least one stop hole on each side of the rotation axis of the operating plate, a stop rod inserted into the stop hole, the end of the stop rod away from the stop hole abutting against the work plate; a cylindrical fixed pile is provided on the operating plate, the axis of the fixed pile is perpendicular to the operating plate, an inner groove is provided on the top surface of the fixed pile, the cross-section of the inner groove is circular, the axis of the inner groove is collinear with the axis of the fixed pile, the fixed pile is divided into a semi-cylindrical left pile and a semi-cylindrical right pile from the top, and a moving assembly is provided in the operating plate for the left pile and the right pile to move closer to each other or further apart in a linear motion.

[0007] As a preferred embodiment of the present invention, the rotating assembly includes a rotating bearing seat fixedly connected to the working plate. There are two rotating bearing seats, which are symmetrical about the operating plate. Each rotating bearing seat is connected to a rotating shaft, and the end of the rotating shaft is fixedly connected to the side of the operating plate.

[0008] In a preferred embodiment of this utility model, the movable component includes a movable groove formed on the operation panel. The movable groove is perpendicular to the rotation axis of the operation panel. One end of the movable groove is set as an open pile, and the side of the movable groove facing the fixed pile is also set as an open pile. A bidirectional lead screw is rotatably connected in the movable groove. The midpoint of the bidirectional lead screw is collinear with the axis of the fixed pile. A left slider and a right slider are threaded to both ends of the bidirectional lead screw, respectively. The sides of both the left and right sliders abut against the inner wall of the movable groove. The left slider extends out of the movable groove and is fixedly connected to the left pile, and the right slider extends out of the movable groove and is fixedly connected to the right pile.

[0009] As a preferred embodiment of this utility model, a material leakage groove is provided on the side of the base, which is connected to the working groove. A material receiving hopper is connected to the side of the base, with the top of the material receiving hopper abutting against the bottom of the material leakage groove. The bottom surface of the working groove is inclined, and the height of the bottom surface of the working groove away from the material receiving hopper is higher than the height of the bottom surface of the working groove near the material receiving hopper.

[0010] In a preferred embodiment of this utility model, the receiving hopper and the base are rotatably connected by a hinge. The hinge is located at the bottom surface of the receiving hopper. An adsorption magnet is embedded on the side of the receiving hopper facing the base. An adsorption iron plate is embedded in the base at the position corresponding to the adsorption magnet. When the hopper and the base come into contact, the adsorption magnet plate and the adsorption iron plate come into contact.

[0011] As a preferred embodiment of this utility model, a placement cylinder is fixedly connected to the side of the working plate, a cleaning rod is inserted into the placement cylinder, and a brush with bristles is fixedly connected to the end of the cleaning rod. Beneficial effects

[0012] The beneficial effects of this utility model are: 1. When grinding the circumferential side of a ring-shaped casting, the base and worktable provide stable support to the operating plate, allowing the casting to be placed stably on the operating plate. The fixing posts on the operating plate have a cylindrical structure that fits snugly against the inner wall of the casting. After the casting is fitted onto the outside of the fixing posts, the fixing posts are separated by a moving component, i.e., the left and right posts move away from each other until they are firmly pressed against the inner wall of the casting, thus completing the fixing of the casting. Since the fixing posts are mainly located on the inner wall of the casting, after the casting is fixed, the circumferential outer wall of the casting is completely exposed above the operating plate. This allows the worker to continuously operate on the circumferential outer wall of the casting, improving the continuity and consistency of the operation, and reducing the area of ​​the circumferential side of the casting when fixing ring-shaped or quasi-ring-shaped castings. Furthermore, the working groove provides rotation space for the operating plate. The operating plate can be rotated under the support of the rotating component by pulling the stop rod out of the stop hole. On the one hand, the rotation of the operating plate makes it easier for workers to process the end face of the casting facing the operating plate. On the other hand, it can quickly pour the debris on the operating plate into the working groove, reducing the obstruction of the debris to the workpiece processing, further improving the processing efficiency and the convenience of the worker's processing.

[0013] 2. The inclined bottom of the working trough guides the debris falling into the working trough, allowing the debris to fall quickly into the receiving hopper for collection, reducing the occurrence of debris falling everywhere and improving the cleanliness of the control panel.

[0014] 3. The designated storage container provides a place for the cleaning rod, preventing it from being lost due to careless handling after use. The cleaning rod, used in conjunction with the brush, effectively removes residual debris from the control panel and work tray, improving the cleanliness of the turntable.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] See Figure 1-2 As shown, a turntable for processing non-ferrous metal alloy castings includes a square-shaped base 1. A rectangular work plate 11 is fixedly connected to the top of the base 1. A placement cylinder 7 is fixedly connected to the side of the work plate 11, and a cleaning rod 71 is inserted into the placement cylinder 7. A brush 72 with bristles 73 is fixedly connected to the end of the cleaning rod 71. A rectangular work groove 111 is formed on the work plate 11, extending into the base 1. A long strip-shaped material discharge groove 6 is formed on the side of the base 1, connecting to the work groove 111. A long strip-shaped receiving hopper 61 is connected to the side of the base 1, with the top of the receiving hopper 61 abutting against the bottom of the material discharge groove 6. The bottom surface of the work groove 111 is inclined, and the height of the bottom surface of the work groove 111 away from the receiving hopper 61 is higher than the height of the bottom surface of the work groove 111 near the receiving hopper 61. The receiving hopper 61 and the base 1 are rotatably connected by a hinge 62. The hinge 62 is located on the bottom surface of the receiving hopper 61. An adsorption magnet 63 is embedded on the side of the receiving hopper 61 facing the base 1. An adsorption iron plate 64 is embedded in the base 1 at the position corresponding to the adsorption magnet 63. When the hopper and the base 1 come into contact, the adsorption magnet and the adsorption iron plate 64 come into contact. After the adsorption magnet 63 is adsorbed on the adsorption iron plate 64, the relative position of the receiving hopper 61 and the base 1 is fixed. The operation is simple and convenient, making it easy for workers to operate.

[0020] refer to Figures 1 to 4A rectangular operating plate 2 is covered on the working groove 111, with its long side parallel to the long side of the working groove 111. A rotating assembly 3 is provided between the working plate 11 and the operating plate 2. The rotating assembly 3 includes two rotating shaft 32 bearings 31 fixedly connected to the working plate 11. The two rotating shaft 32 bearings 31 are symmetrical about the operating plate 2, and each rotating shaft 32 bearing 31 is connected to a rotating shaft 32. The end of the rotating shaft 32 is fixedly connected to the midpoint of the side of the operating plate 2. The rotating shaft 32 bearings 31 on both sides drive the operating plate 2 to rotate, so that the operating plate 2 can be flipped to pour the surface debris into the working groove 111, reducing the amount of debris on the surface of the operating plate 2 and improving the cleanliness of the operating plate 2. On the other hand, after the operating plate 2 is flipped, the position of the casting facing the working plate 11 can be changed to the opposite direction of the working plate 11, which is convenient for workers to operate and observe, and improves the flexibility of the use of the operating plate 2.

[0021] refer to Figures 1 to 4 The operating plate 2 has a stop hole 21 on the side facing the bearing 31 of the rotating shaft 32. The axis of the stop hole 21 is parallel to the axis of the rotating shaft 32. At least one stop hole 21 is provided on both sides of the rotating shaft 32 of the operating plate 2. A stop rod 22 is inserted into the stop hole 21. The end of the stop rod 22 away from the stop hole 21 is bent and abuts against the working plate 11. The stop rod 22 is L-shaped. The stop rod 22 can limit the rotation of the operating plate 2 by its own hardness. On the other hand, when the worker rotates the operating plate 2, the stop rod 22 can provide the worker with a gripping position, making it easier for the worker to rotate the operating plate 2.

[0022] refer to Figures 1 to 4 The operating plate 2 is equipped with a cylindrical fixing pile 4. The axis of the fixing pile 4 is perpendicular to the operating plate 2. The top surface of the fixing pile 4 is provided with an inner polishing groove 43. The inner polishing groove 43 has a circular cross-section. The axis of the inner polishing groove 43 is collinear with the axis of the fixing pile 4. When the worker performs circumferential inner surface processing on the ring casting, the casting is placed in the inner polishing groove 43. The inner polishing groove 43 can be fixed by clamping the outer side of the workpiece, so that the equipment can meet the fixing requirements when processing the outer side of the workpiece and when processing the inner side of the workpiece.

[0023] refer to Figure 4The fixed pile 4 is divided into a semi-cylindrical left pile 41 and a semi-cylindrical right pile 42 from its top. The inner chute 43 is also divided into the left pile 41 and the right pile 42. The operating plate 2 is provided with a moving component 5, which includes a moving groove 51 opened on the operating plate 2. The moving groove 51 is perpendicular to the rotation axis 32 of the operating plate 2. One end of the moving groove 51 is set as an open pile. The side of the moving groove 51 facing the fixed pile 4 is set as an open pile. A double-acting screw 52 is rotatably connected in the moving groove 51. The midpoint of the double-acting screw 52 is collinear with the axis of the fixed pile 4. The two ends of the double-acting screw 52 are respectively threaded to a left slider 53 and a right slider 54. The sides of the left slider 53 and the right slider 54 abut against the inner wall of the moving groove 51. The left slider 53 extends out of the moving groove 51 and is fixedly connected to the left pile 41. The right slider 54 extends out of the moving groove 51 and is fixedly connected to the left pile 41. A handle 8 is fixedly connected to the right pile 42 and extends from the open end of the moving groove 51 of the bidirectional screw 52. The handle 8 is arranged in a ring shape and is connected to the end of the bidirectional screw 52 through an auxiliary rod 81. The handle 8 rotates synchronously with the bidirectional screw 52. Multiple auxiliary rods 81 are provided. Each auxiliary rod 81 is fixedly connected at one end to the end of the bidirectional screw 52 and at the other end to the handle 8. The multiple auxiliary rods 81 are radially distributed with the end of the bidirectional screw 52 as the center. There are gaps between adjacent auxiliary rods 81. A limiting hole 9 is opened on the side of the operating plate 2 facing the handle 8. A limiting rod 91 is inserted into the limiting hole 9. The end of the limiting rod 91 away from the limiting hole 9 passes through the gap of the auxiliary rod 81 and then passes through the handle 8. When the limiting rod 91 is inserted into the limiting hole 9, the handle 8 stops rotating.

[0024] One specific application of this embodiment is: In use, the worker first places the annular casting onto the fixed stake 4. Then, the worker pulls out the limiting rod 91 from the limiting hole 9. After pulling it out, the worker rotates the handle 8 to drive the double-acting screw 52 to rotate. The double-acting screw 52 drives the left slider 53 and right slider 54 to move away from each other. The left slider 53 and right slider 54 drive the left stake 41 and right stake 42 to move synchronously. After the left stake 41 and right stake 42 abut against the inner wall of the casting, the worker can move the casting up and down to a suitable processing position. Then, the worker rotates the handle 8 again to make the left stake 41 and right stake 42 press firmly against the inner wall of the casting. The casting is fixed to the outside of the left stake 41 and right stake 42 by static friction. Then, the worker inserts the limiting rod 91 through the handle 8 and the auxiliary rod 81 into the limiting hole 9, restricting the rotation function of the handle 8, thereby fixing the relative position of the left slider 53 and right slider 54.

[0025] Workers polish the circumferential outer wall of the casting. During polishing, debris falls directly onto the operating plate 2. Some debris falls through the edge of the operating plate 2 into the working groove 111. After processing, the worker rotates the stop levers 22 one by one. When all stop levers 22 are no longer in contact with the working plate 11, the worker holds the stop levers 22 and rotates the operating plate 2. The debris remaining on the operating plate 2 falls into the working groove 111 due to gravity. The worker then removes the cleaning rod 71 from the placement cylinder 7 and uses the brush 72 connected to the cleaning rod 71 to sweep the debris from the working plate 11 into the working groove 111 for collection. After use, the brush 72 is returned to the placement cylinder 7. After the debris falls into the working groove 111, the bottom wall of the working groove 111 guides the debris, causing it to roll towards the receiving hopper 61 for collection. Once the receiving hopper 61 is full of debris, the worker can simply rotate it downwards by turning it away from the base 1, causing the debris to be poured out and becoming the initial solid raw material for casting. In summary, through the above steps, the occlusion area on the circumferential sides of the casting is reduced when fixing ring-shaped or near-ring-shaped castings.

[0026] Of course, the above description is not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, alterations, additions or substitutions made by those skilled in the art within the scope of the present utility model should be protected by the present utility model.
