Description

Technical Field

[0001] This utility model relates to the field of clamps, and in particular to a hydraulic clamp structure. Background Technology

[0002] A fixture is a device used in the mechanical manufacturing process to fix the workpiece in the correct position for construction or inspection.

[0003] Existing hydraulic clamps typically drive corresponding hydraulic drive devices via hoses, which generally include inlet and outlet channels, thus achieving hydraulic drive.

[0004] However, when the fixture needs to be flipped, the requirements for the hydraulic pipeline are also higher. Existing methods generally use a pipe winding structure or a rotating structure to prevent the hydraulic pipeline from detaching. However, this structure also has the problem of messy pipelines, which affects the stability of the fixture.

[0005] For example, Chinese patent 202420851958.0 involves multiple hydraulic drive structures. If pipes are installed one by one, the fixture will be quite messy and the rotation angle will be small. Utility Model Content

[0006] The main purpose of this utility model is to propose a hydraulic clamp structure, which aims to improve the hydraulic drive structure of existing hydraulic clamps, realize a pipe-free or non-interfering pipe structure, thereby enabling stable flipping of the clamp, while ensuring the stability of the clamp structure.

[0007] To achieve the above objectives, this utility model proposes a hydraulic clamp structure, comprising:

[0008] The base is provided with a first output channel and a first return channel;

[0009] The base has two bases spaced apart, and each base has a pivot hole;

[0010] A flip plate, wherein both ends of the flip plate are provided with bearing seats that extend into pivot holes, and the flip plate is provided with multiple hydraulic drive devices;

[0011] The flip plate is provided with a second output channel and a second return liquid channel;

[0012] The base is provided with a first branch output channel and a first branch return channel.

[0013] The first branch output channel is connected to the first output channel, and the first return channel is connected to the first branch return channel;

[0014] The bearing seat is provided with a second branch output channel and a second branch return channel. The first branch output channel and the second branch output channel are connected to each other, and the first branch return channel and the second branch return channel are also connected to each other.

[0015] A substrate, disposed on a shaft seat, is provided with a third branch output channel and a third branch return channel.

[0016] The third branch output channel is connected to the second branch output channel, and the third branch return channel is connected to the second branch return channel.

[0017] The other end of the third branch return channel is connected to the second output channel via a first flexible tube.

[0018] The other end of the third branch return channel is connected to the second return channel via a second hose.

[0019] In the actual design, the tilting plate is pivotally mounted to the base via a bearing seat. By incorporating liquid channels in the base, base, tilting plate, bearing seat, and base plate, most of the pipes are internally integrated, reducing pipe interference. This ensures that the tilting plate can rotate without tangling pipes, and its rotation angle remains unaffected.

[0020] Meanwhile, by setting up a liquid channel in the tilting plate, multiple hydraulic drive devices can be operated simultaneously, and its structure is stable in use. Attached Figure Description

The staggered structure is adopted, thereby realizing the relative independence and sealing of the output channel and the return channel. At the same time, the bearing seat 4 will not have the problem of tube wrapping when rotating, and the rotation will not affect the liquid delivery.
