[0034] See also Figure 1-Figure 2 As shown, a hydraulic clamp of a thin shell includes a base 1, on which a support block 2 is provided, and the support block 2 corresponds to the position of the earring 31 of the product 3. Specifically, the earring 31 has an inner hole of the earring, and the support block 3 has a positioning column inserted into the inner hole of the earring. A clamping component 4 is provided on the base 1 and is pressed on the earring from top to bottom. The clamping component 4 is used in conjunction with the support block 2, and acts together on the upper and lower ends of the earring 31 of the product to clamp the product. A positioning pin seat 5 is provided on the base 1, and the positioning pin seat 5 has a positioning pin corresponding to the positioning pin hole of the product.

[0035] In this embodiment, the base 1 has a sunken groove 101; there are two support blocks 2 and two positioning pin seats 5, and the support blocks 2 and the positioning pin seats 5 are distributed around the sunken groove 101. When the product 3 is placed on the support block 2 and the positioning pin seat 5, the lower end of the product 3 is suspended above the sunken groove 101.

[0036] Three foolproof blocks 7 are arranged on the base 1. The foolproof blocks 7 are distributed around the product. The upper ends of the foolproof blocks have grooves for placing the outer edges of the products. The grooves of the three foolproof blocks 7 are different and are distributed in a triangular shape around the periphery of the sunken groove 101. When the product 3 is correctly placed, it can be inserted into the groove. When the product is placed incorrectly, it cannot be placed into the groove. On-site personnel can directly observe whether the product is placed correctly to avoid processing problems caused by abnormal product placement.

[0037] In this embodiment, a support cylinder 6 is provided on the base 1, the bottom of the support cylinder 6 is supported on the bottom plate 1 and the reverse side of the upper end is pressed against the lower end surface of the product. When the tool is cutting, the support cylinder can provide a stable and effective support force, effectively alleviating the high-frequency vibration of the tool caused by factors such as cutting force changes, thereby making the processing process more stable and smooth, reducing product deformation, and ensuring the rigidity of the product during processing.

[0038] Preferably, the support cylinder 6 is an adjustable speed hydraulic cylinder, which can accurately control the extension and retraction speed of the cylinder piston rod to provide a stable supporting force for the product.

[0039] In this embodiment, an oil circuit connected to the support cylinder is arranged in the base 1, and the oil circuit forms an oil inlet and an oil outlet on the base 1. The above structural design reduces the oil circuit pipeline exposed to the outside, thereby improving the overall aesthetic visual effect.

[0040] In this embodiment, a tool setting hole is provided on the base 1 to provide a reference point for tool processing.

[0041] In this embodiment, the clamping assembly 4 includes a clamping cylinder 41 fixed on the base 1, the piston end of the clamping cylinder 41 is hinged to one end of a clamping plate 42 through a floating joint, the other end of the clamping plate 42 is clamped on the earring, the middle of the clamping plate 42 is hinged to the upper end of a bracket 43, and the lower end of the bracket 43 is hinged to the cylinder body of the clamping cylinder. Through the above structural design, the clamping plate 42 acts on the earring of the product using the principle of a lever to clamp the product and prevent the product from moving vertically during processing.

[0042] Preferably, the other end of the pressing plate 42 has a downward columnar protrusion, which corresponds to the positioning column on the support block 2 up and down, so that the force on the product in the vertical direction is balanced, thereby improving the stability of product placement.

[0043] In this embodiment, the base 1 is provided with a plurality of air blowing pipes 8, which are bent and tilted toward one side of the product, and the air blowing ports of the air blowing pipes 8 are higher than the height of the product.

[0046] The locating pins on the locating pin seat 5 are used to prevent the product from deflecting at the horizontal angle, and the product is pressed by the support block 2 and the clamping assembly 4 to prevent its vertical position from shifting. The anti-mistake block 7 ensures that the product is placed correctly and provides a certain vertical support for the product. On this basis, a support cylinder 6 is added to clamp the product on the back side. When the tool is performing cutting operations, the support cylinder 6 can provide a stable and effective support force, effectively alleviating the high-frequency vibration of the tool caused by factors such as changes in cutting force, thereby making the processing process smoother and smoother, reducing product deformation, and ensuring the rigidity of the product during processing. At the same time, the back side of the product 3 is clamped by the support cylinder 6 to provide support for the bottom of the product, which solves the stability of the product during tooling processing and the problem of high scrap rate caused by deformation of the thin shell.
