[0020] The following details this utility model, clearly and completely describing the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of this utility model.

[0021] The present utility model provides an anti-corrosion fixture jaw through improvement. The technical solution of the present utility model is as follows:

[0022] As Figure 1 - Figure 2 shown, an anti-corrosion fixture jaw includes a jaw main body 1. The jaw main body 1 includes a gripper main body 10, and further includes: a protection component, which is arranged outside the gripper main body 10; the protection component includes a rear jaw 12 and a front jaw 13 installed on the lower side of the gripper main body 10. A front waterproof slide plate 3 is fixed to the lower end of the front jaw 13, a rear waterproof slide plate 14 is fixed to the lower end of the rear jaw 12, a lower waterproof slide plate 16 is fixed to one side of the rear waterproof slide plate 14, a gripper waterproof shell 4 is fixed to the lower end outside the gripper main body 10, and a gripper upper guard plate 8 is fixed to the upper end outside the gripper main body 10. A gripper front guard plate 5 is fixed to the front end outside the gripper main body 10, and a gripper rear guard plate 9 is fixed to the rear end outside the gripper main body 10. A gripper left guard plate 7 is fixed to one side of the gripper main body 10, and a gripper right guard plate 11 is fixed to the other side of the gripper main body 10; the gripper main body 10 is surrounded and protected by corrosion-resistant material processing parts on all sides and above, which can effectively isolate corrosive gases and liquids.

[0023] As Figure 2 shown, in one embodiment, a front clamping plate 2 is fixed to the lower end of the front waterproof slide plate 3, and a rear clamping plate 17 is fixed between the rear waterproof slide plate 14 and the lower waterproof slide plate 16. The workpiece is clamped by the front clamping plate 2 and the rear clamping plate 17.

[0024] As Figure 2 shown, in one embodiment, a left positioning fork 6 is fixed to one side of the gripper left guard plate 7, and a right positioning fork 15 is fixed to one side of the gripper right guard plate 11. The fixture can be positioned through the left positioning fork 6 and the right positioning fork 15 to prevent the fixture from sticking.

[0025] As Figure 2 shown, in one embodiment, the gripper main body 10 is fixedly connected to the gripper waterproof shell 4, the gripper front guard plate 5, the gripper upper guard plate 8, and the gripper rear guard plate 9 by screwing, which is convenient for installation and disassembly. When maintenance is required, only the gripper front guard plate 5 needs to be removed to repair the air circuit of the gripper main body 10.

[0026] As Figure 2 shown, in one embodiment, except for the gripper main body 10, the rest are made of nickel alloy material. Nickel alloy has excellent corrosion resistance and is suitable for high-temperature, high-pressure, and corrosive environments.

[0027] The specific working method is as follows: The periphery and the upper part of the gripper body 10 are surrounded and protected by corrosion-resistant material processing parts, which can effectively isolate corrosive gases and liquids. The gripper body 10 needs to transfer the clamping action from the rear gripper 12 and the front gripper 13 to the front clamping plate 2 and the rear clamping plate 17. Therefore, the lower part of the gripper body 10 must leave a moving space for the rear gripper 12 and the front gripper 13, and it cannot be completely isolated by fixed parts. The front waterproof slide plate 3, the rear waterproof slide plate 14, and the lower waterproof slide plate 16 of the present invention can slide back and forth with the clamping plate, completely protecting and sealing the moving space at the lower part of the gripper body 10, preventing the lower part of the gripper body 10 from contacting corrosive gases and liquids. The left positioning fork 6 and the right positioning fork 15 can position the hanger when the hanger enters the clamping plate, preventing the hanger from colliding with the clamping plate. When the clamping plate is opened while clamping the hanger, it can prevent the hanger from adhering to the clamping plate. Just remove the front gripper guard plate 5 to conveniently adjust and repair the air circuit of the gripper body 10.

[0028] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed by the above technical means, but also include the technical solutions composed of equivalent replacements of the above technical features. The matters not covered by the present utility model belong to the common general knowledge of those skilled in the art.
