Description

Technical Field

[0001] The utility model belongs to the field of metal casting processing, in particular to a metal casting feeding clamping device. Background Art

[0002] Metal casting is a process of melting metal into a liquid that meets certain requirements and pouring it into a mold. After cooling, solidification and cleaning, a casting with a predetermined shape, size and performance is obtained. In the process of metal casting production, in order to make the metal casting better conform to the predetermined shape, it is necessary to use processing equipment to further process the metal casting; before processing, the metal casting needs to be clamped and fixed to reduce the vibration generated during processing and improve the processing accuracy.

[0003] However, in actual use, the main technical problem is that the existing clamping mechanism usually uses a threaded rod or a cylinder to drive the clamping block for clamping. Although it can adapt to metal parts of different sizes, the clamping is not firm enough and the metal casting cannot be driven to rotate during the processing to change the processing angle. In addition, after the current metal casting is processed, the next metal part needs to be transported to the processing station to wait for processing. The entire loading time is long, and it is difficult to process metal parts in batches and continuously. Utility Model Content

[0015] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0016] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0017] For the convenience of explanation, only the parts related to the embodiment of the present utility model are shown.

[0018] Combination Figure 1-3 As shown, the feeding clamping device includes a machine table 1, and the machine table 1 is provided with a feeding mechanism, a clamping rotating mechanism from front to back in sequence, and the clamping rotating mechanism includes a driving box 2 and a clamping seat 3 arranged opposite to each other. A rotating shaft 4 is rotatably arranged in the driving box 2, and a power wheel 5 is arranged at the outer end of the rotating shaft 4, and a push rod 6 is arranged at the inner end. A push plate sleeve 7 is sleeved on the push rod 6, and a stand 8 is provided on the machine table 1, and a push cylinder 9 is provided on the stand 8. The driving shaft of the push cylinder 9 is provided with a connecting rod. A connecting plate 10 is provided with a pair of pull rods 11, the pull rods 11 pass through the drive box 2 and are connected to the push plate sleeve 7, a clamping rod 13 is inserted into the clamping seat 3, a clamping sleeve 14 is provided at the inner end of the clamping rod 13, the clamping sleeve and the push rod are arranged oppositely, a clamping cylinder 15 is provided on the clamping seat 3, the driving shaft of the clamping cylinder 15 is rotatably connected to the clamping rod 13, and a driving motor 16 for driving the power wheel 5 to rotate is provided in the machine platform 1.

[0019] In this embodiment, the metal casting is in the shape of a truncated cone, and a through hole is formed at the axis of the metal casting. After the metal casting is produced, in order to make the metal casting better conform to the predetermined shape, it is necessary to use a processing device to further process the metal casting. Before processing, the metal casting can be clamped and fixed by the device to facilitate subsequent processing.

[0020] When processing metal castings in batches, the metal castings are dropped onto the feeding mechanism as required, and the feeding mechanism delivers the metal castings to the processing stations one by one. At this time, the clamping cylinder drives the clamping rod to move toward the current metal casting, and the clamping sleeve moves the current clamping sleeve toward the metal casting until the push rod and the clamping sleeve clamp the current metal casting. After that, the processing mechanism can process the metal casting. In this process, the drive motor drives the power wheel to rotate, and the push rod will drive the metal casting to rotate synchronously until the processing is completed, thereby realizing fine processing of the metal casting.

[0021] In this structure, Figure 3 , the inner end surface of the push rod 6 is provided with a circle of protrusions 17, and the core shaft 18 is provided at the axial position of the inner end surface. By providing a circle of protrusions on the inner end surface of the push rod, the metal casting can be clamped more securely. When the metal casting is being clamped, the clamping sleeve pushes the metal casting toward the push rod. First, the core shaft is inserted into its through hole, and the metal casting is then clamped by the push rod and the clamping sleeve. In the process of clamping, the core shaft plays a guiding role, making the metal casting more stable during the clamping process. At the same time, it prevents the metal casting from falling after being clamped.

[0022] The table top of the machine 1 is provided with a material discharge port 19. When the metal casting is processed, the clamping rod is reset under the action of the clamping cylinder, and then the push cylinder drives the pull rod to move inward, and the push plate sleeve moves toward the metal casting and pushes the metal casting to the right until the core shaft is separated from the metal casting. Finally, the metal casting is clamped by the material discharge clamp and transferred to the material discharge port for discharge. Figure 1 As shown, the machine is provided with a receiving box 35, and the processed metal castings are centrally discharged to the receiving box for centralized collection. The material discharge clamp is not the key content in this device, so it is not described here.

[0023] As a preferred structure, Figure 1-2 The feeding mechanism includes a fixed frame 20, on which an inclined feeding frame 21 is provided, and a discharge port 22 is provided at the bottom of the feeding frame. A slide seat 23 is provided on the fixed frame 20 corresponding to the discharge port, and a feeding bracket 24 is slidably provided in the slide seat 23. A support block 25 is provided at the end of the feeding bracket 24, and a clamping block 26 is rotatably provided on the support block 25. Short columns 27 are provided on the support block 25 and the clamping block 26, and a tension spring 28 is provided between the two short columns on the same side. The fixed frame 20 is also provided with a sliding cylinder 29 for driving the feeding bracket to slide.

[0024] In this structure, the support block and the clamping block constitute a loading carrier, when the metal castings need to be loaded one by one and orderly to the processing station. First, the loading carrier is located directly below the discharge port, and the metal casting at the bottom falls from the discharge port to the loading carrier. The sliding cylinder drives the loading bracket to slide backward until the metal casting is loaded to the processing station, and then the clamping and rotating mechanism processes it and performs corresponding processing. It is worth mentioning that during the loading process of the metal castings, the loading bracket will always cover the discharge port to prevent the remaining metal castings from falling from the discharge port.

[0025] In addition, when the metal casting falls from the discharge port to the support block, the metal casting will move downward along the inner wall of the clamping block until it moves to the bottom of the support block. In this process, due to the action of the tension spring, the clamping block has the function of pre-tightening the metal casting, which can slightly clamp the metal casting to prevent it from falling.

[0026] In addition, if Figure 2 The machine 1 is also provided with a mounting plate 30, and a lifting screw 31 is inserted upward into the mounting plate. The top of the lifting screw 31 is connected to the fixed frame 20, and a rotating handle 32 is provided at the bottom. A pair of sliding sleeves 33 are provided on both sides of the lifting screw on the mounting plate, and a sliding rod 34 is inserted into each sliding sleeve 33, and the top of the sliding rod is connected to the fixed frame.

[0027] In this structure, the overall height of the loading rack can be fine-tuned. In actual situations, when the height of the loading rack is to be adjusted, the rotating handle is first rotated, and the lifting screw moves up and down to adjust the loading rack. During the vertical movement of the lifting screw, the slide bar slides up and down in the corresponding slide sleeve to improve the stability of the entire adjustment process.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the present utility model.
