Description

Technical Field

[0001] This utility model relates to the field of casting and processing technology, specifically to a clamping device for cold iron processing with adjustable function. Background Technology

[0002] In the foundry industry, chills are crucial process components for controlling the solidification sequence of castings, and their machining accuracy directly affects the microstructure and forming quality of the castings. Chills are typically made of materials such as cast iron and steel, and during machining, they need to be fixed by clamping devices before being cut, ground, drilled, and subjected to other processes.

[0003] Existing clamping devices for chill processing often cannot freely adjust the clamping angle according to processing requirements, thus limiting the practicality of the device. Furthermore, when clamping chill workpieces, the clamping structure can easily obstruct the processing equipment, affecting the smooth progress of the processing operation. Therefore, a new technical solution is proposed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping device for cold iron processing with adjustable function, which solves the problem mentioned in the background art that the existing clamping devices for cold iron processing often cannot freely adjust the clamping angle according to processing requirements, thus limiting the practicality of the device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a clamping device for cold iron processing with adjustable function, comprising a worktable and a top frame, wherein a bottom arc-shaped frame is slidably connected through the top surface of the worktable, and vertical plates are fixedly connected to the top surfaces of the worktable on both the front and rear sides of the bottom arc-shaped frame, and support rods are fixedly connected to the front and rear sides of the bottom arc-shaped frame, with the other end of the support rods rotatably connected to the surface of the vertical plates.

[0006] In this technical solution, by setting a bottom arc frame on the surface of the worktable, the bottom arc frame rotates around the support rod as the axis, thereby generating an inclination angle. When clamping the chilled workpiece, the angle can be flexibly set according to the current processing requirements, so that the device can better adapt to different processing scenarios and significantly improve the practicality of the device in actual use.

[0007] Preferably, a top arc frame is fixedly connected to both sides of the top edge of the bottom arc frame, a sleeve block is fitted and slidably on the surface of the top arc frame, a compression bolt is threaded onto the surface of the sleeve block, and the bottom ends of the top frame are fixedly connected to the sleeve blocks on both sides respectively.

[0008] Preferably, the top of the top frame is provided with a top groove, and a bidirectional lead screw is rotatably connected to the inner side of the top groove. Two threaded sleeves pass through the surface of the bidirectional lead screw and are threadedly connected to the threaded sleeves. A clamping plate is fixedly connected to the bottom of the threaded sleeves.

[0009] Preferably, a central groove is provided at the top center of the bottom arc frame, and a first electric actuator is fixedly connected to the bottom surface of the bottom arc frame directly below the central groove. The telescopic end of the first electric actuator passes through the surface of the bottom arc frame and connects with the support plate inside the central groove.

[0010] Preferably, side plates are fixedly connected to the left and right edges of the bottom arc frame, and a second electric actuator is fixedly connected to the top surface of the side plate. The telescopic end of the second electric actuator passes through the surface of the side plate and is fixedly connected to the abutment plate through a hinge seat.

[0011] Preferably, a first servo motor is fixedly connected to the outer surface of the top frame, and the tail end of the drive shaft of the first servo motor is connected to one end of a bidirectional lead screw through a coupling. A second servo motor is fixedly connected to the outer surface of one of the vertical plates, and the tail end of the drive shaft of the second servo motor is connected to one end of a support rod through a coupling.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model provides a bottom arc-shaped frame on the surface of the workbench. The bottom arc-shaped frame rotates around the support rod as the axis, thereby generating an inclination angle. When clamping chilled iron workpieces, the angle can be flexibly set according to the current processing requirements, so that the device can better adapt to different processing scenarios and significantly improve the practicality of the device in actual use.

[0014] 2. This utility model has a top arc frame at the top of the bottom arc frame. The top frame can rotate along the surface of the top arc frame and drive the clamping plate to tilt. This not only enables precise clamping of cold iron workpieces at different angles during actual use, but also allows for flexible adjustment of the tilt angle according to clamping requirements. This effectively avoids the clamping structure from obstructing the processing equipment, providing more convenience for processing operations and further improving the practicality and applicability of the device.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.

[0021] A clamping device for cold iron processing with adjustable function, see [link to relevant documentation] Figures 1 to 3 The device includes a worktable 1 and a top frame 5. A bottom arc frame 2 is slidably connected to the top surface of the worktable 1. Vertical plates 12 are fixedly connected to the top surfaces of the worktable 1 on both the front and rear sides of the bottom arc frame 2. Support rods 13 are fixedly connected to the front and rear sides of the bottom arc frame 2. The other end of the support rod 13 is rotatably connected to the surface of the vertical plate 12. A second servo motor 131 is fixedly connected to the outer surface of one of the vertical plates 12. The tail end of the drive shaft of the second servo motor 131 is connected to one end of the support rod 13 through a coupling. In actual use, the second servo motor 131 starts and drives the support rod 13 to rotate, thereby driving the entire bottom arc frame 2 to rotate, causing the surface of the bottom arc frame 2 to move at an angle. When clamping chilled workpieces, the angle can be freely set, allowing the device to be adjusted according to the current processing requirements during actual use, thus improving its practicality.

[0022] Specifically, such as Figure 2 As shown, a central groove 201 is provided at the top center of the bottom arc frame 2. A first electric actuator 202 is fixedly connected to the bottom surface of the bottom arc frame 2 directly below the central groove 201. The telescopic end of the first electric actuator 202 passes through the surface of the bottom arc frame 2 and is connected to the support plate 203 inside the central groove 201. During the clamping process, in order to facilitate rotation, there is a certain distance between the clamping plate 8 and the surface of the bottom arc frame 2. Therefore, in order to increase the contact area with the clamping plate 8 during clamping, the first electric actuator 202 is activated, which drives the support plate 203 to rise, thereby increasing the height of the chilled workpiece so that it can fully contact the clamping plate 8 and improve the stability of clamping.

[0023] Furthermore, such as Figure 1As shown, a top arc frame 3 is fixedly connected to both sides of the top edge of the bottom arc frame 2. A sleeve block 4 is fitted and slides on the surface of the top arc frame 3. A pressing bolt 401 is threadedly connected to the surface of the sleeve block 4. After the pressing bolt 401 is tightened, the sleeve block 4 will be tightly pressed against the surface of the top arc frame 3, thereby keeping the top frame 5 stable. The bottom two ends of the top frame 5 are fixedly connected to the sleeve blocks 4 on both sides respectively. The sleeve block 4 slides on the surface of the top arc frame 3, thereby driving the entire top frame 5 to rotate. This not only allows for clamping of chilled iron workpieces at different angles during actual use, but also allows for adjustment of the tilt angle according to clamping requirements so as not to obstruct the processing equipment, further improving the practicality of the device.

[0024] It is worth noting that, such as Figure 1 As shown, side plates 9 are fixedly connected to the left and right edges of the bottom arc frame 2. A second electric push rod 10 is fixedly connected to the top surface of the side plate 9. The telescopic end of the second electric push rod 10 passes through the surface of the side plate 9 and is fixedly connected to the abutment plate 11 through the hinge seat. After the bottom arc frame 2 is adjusted to an angle, the second electric push rod 10 is activated, which drives the abutment plate 11 to descend until it is in close contact with the surface of the worktable 1. At this time, the second servo motor 131 can be de-energized normally. The second electric push rods 10 and the abutment plate 11 on both sides can keep the bottom arc frame 2 stable and ensure stability during the processing.

[0025] It is worth noting that, such as Figure 2 As shown, the top of the top frame 5 has a top groove 501. A bidirectional lead screw 6 is rotatably connected to the inner side of the top groove 501. A first servo motor 601 is fixedly connected to the outer surface of the top frame 5. The tail end of the drive shaft of the first servo motor 601 is connected to one end of the bidirectional lead screw 6 through a coupling. Two threaded sleeves 7 pass through the surface of the bidirectional lead screw 6 and are threadedly connected to the threaded sleeves 7. A clamping plate 8 is fixedly connected to the bottom of the threaded sleeves 7. When clamping is required, the first servo motor 601 is started, which drives the two threaded sleeves 7 and their respective clamping plates 8 to move closer to each other, thereby clamping the chilled iron workpiece placed at the center of the top of the bottom arc frame 2. It can clamp the workpiece in any direction, avoiding obstruction of the processing equipment.

[0026] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.
