Description

Technical Field

[0001] This utility model relates to the field of hydraulic clamping technology, and in particular to a multi-layer metal plate hydraulic clamping device with concealable oil circuits. Background Technology

[0002] Traditional hydraulic clamps have their oil pipes distributed externally, which is complex and exposed. During equipment operation and clamp rotation, the oil pipes are prone to wear and scratches and are exposed to harsh environments for a long time, which can easily cause problems such as aging, hardening, and breakage of the hoses.

[0003] Traditional concealed hydraulic clamps are manufactured using drilling technology and can only be simply distributed in a single layer. They also require work such as sealing the other end of some through holes. To address these issues, we propose a safe, reliable, compact, and highly reliable hydraulic clamp made of multi-layer metal plates that can conceal the hydraulic circuit. Utility Model Content

[0004] Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a multi-layer metal plate hydraulic clamp with concealable oil circuits, which solves the technical problems of traditional hydraulic clamps having complex oil pipe distribution, being exposed, being prone to wear, and having a cumbersome manufacturing process.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A multi-layer metal plate hydraulic clamp with concealable oil circuits includes an upper plate, a middle plate and a lower plate. The bottom surface of the upper plate has a first oil groove, the upper surface of the lower plate has a second oil groove, and the surface of the middle plate has an oil groove through hole. The first oil groove communicates with the second oil groove through the oil groove through hole.

[0009] Preferably, the upper layer plate, middle layer plate, and lower layer plate are welded and fixed.

[0010] Preferably, the upper, middle, and lower layers are all individually processed and formed.

[0011] Preferably, the upper layer, middle layer, and lower layer are distributed from top to bottom. Beneficial effects

[0012] I. This hydraulic clamp with concealed oil circuits, made of multi-layer metal plates, greatly reduces the overall area of ​​the clamp by hiding the oil circuits between the layers. It can make more effective use of the machine tool stroke and worktable area. Compared with clamps made by traditional drilling process, its oil circuit design is more complex and efficient, achieving vertical connection and avoiding the limitations of simple vertical and horizontal distribution of single layer. It also eliminates tedious processes such as leak sealing, improving the functionality and reliability of the clamp.

[0013] Second, the multi-layer metal plates of this hydraulic clamp with concealed oil circuits can be welded into one piece by selecting different welding methods according to the required pressure. When the pressure is less than 10 MPa, vacuum brazing and other methods can be used, and when the pressure is greater than 10 MPa, vacuum diffusion welding can be used. The flexible welding selection allows the clamp to adapt to various working pressure environments, ensuring stable performance and reliable sealing under different working conditions, extending the service life of the clamp and reducing maintenance costs.

[0020] This application provides a multi-layer metal plate hydraulic clamp with concealable oil circuits, effectively solving the problems of complex oil pipe distribution, exposed oil pipes, easy wear, and cumbersome manufacturing processes in traditional hydraulic clamps. This multi-layer metal plate with concealable oil circuits greatly reduces the overall area of ​​the clamp by hiding the oil circuits between the layers, allowing for more efficient utilization of machine tool travel and worktable area. Compared to clamps manufactured using traditional drilling processes, its oil circuit design is more complex and efficient, achieving vertical continuity and avoiding the limitations of simple single-layer distribution. It also eliminates cumbersome processes such as leak sealing, improving the functionality and reliability of the clamp. This multi-layer metal plate with concealable oil circuits can be welded into a single unit using different welding methods depending on the required pressure. When the pressure is less than 10 MPa, vacuum brazing can be used; when the pressure is greater than 10 MPa, vacuum diffusion welding can be used. This flexible welding selection allows the clamp to adapt to various working pressure environments, ensuring stable performance and reliable sealing under different working conditions, extending the clamp's service life and reducing maintenance costs.

[0021] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problems of traditional hydraulic clamps having complex oil pipe distribution, being exposed, easily worn, and having a cumbersome manufacturing process. The overall idea is as follows:

[0022] To address the problems existing in the prior art, this utility model provides a multi-layer metal plate hydraulic clamp with concealable oil circuits, including an upper plate 1, a middle plate 2, and a lower plate 3. A first oil groove 4 is formed on the bottom surface of the upper plate 1, a second oil groove 6 is formed on the upper surface of the lower plate 3, and an oil groove through-hole 5 is formed on the surface of the middle plate 2. The first oil groove 4 communicates with the second oil groove 6 through the oil groove through-hole 5. The upper plate 1, middle plate 2, and lower plate 3 are welded and fixed. Each of the upper plate 1, middle plate 2, and lower plate 3 is individually machined; single-layer machining allows for the milling of complex oil circuits. The upper plate 1, middle plate 2, and lower plate 3 are distributed sequentially from top to bottom. The fixture is made of multiple layers of plates, including an upper plate 1, a middle plate 2, and a lower plate 3, welded together. This allows the first oil groove 4 and the second oil groove 6 to be connected vertically through the oil groove through-hole 5, greatly reducing the area of ​​the fixture. It effectively utilizes the machine tool's stroke and the area of ​​the worktable, solving the problems of traditional internal hydraulic fixtures which can only be made using drilling technology and have a simple single-layer longitudinal and transverse distribution, and require the sealing of the other end of some through holes. Depending on the pressure required by the hydraulic fixture, different welding methods are used to weld the multiple plates into one piece. If the pressure is less than 10 MPa, vacuum brazing can be used, and if the pressure is greater than 10 MPa, vacuum diffusion welding can be used.

[0023] Working principle:

[0024] The first step involves welding multiple layers of plates, including an upper plate 1, a middle plate 2, and a lower plate 3, to achieve vertical connection between the first oil groove 4 and the second oil groove 6 through the oil groove through hole 5. This significantly reduces the area of ​​the clamp and effectively utilizes the machine tool's stroke and the worktable's area. It also solves the problems of traditional internal hydraulic clamps, which can only be made using drilling technology and have a simple single-layer longitudinal and transverse distribution, and require sealing the other end of some through holes.

[0025] The second step is to weld the multi-layer plates into one piece using different welding methods according to the pressure required by the hydraulic clamp. If the pressure is less than 10 MPa, vacuum brazing or other methods can be used, and if the pressure is greater than 10 MPa, vacuum diffusion welding can be used.

[0026] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
