Fig. 1 is a schematic view of the installation of the present invention;
in the figure, 1 a jaw main body, 11 a first connecting hole, 12 a second connecting hole, 2 a clamping block and 21 steps are pressed.
Detailed Description
The first embodiment is as follows: the embodiment is described with reference to fig. 1, and provides an auxiliary jaw of a fixture for processing a steam passage of a steam turbine blade, the auxiliary jaw comprises a jaw main body 1 and a clamping block 2, the jaw main body 1 is a cuboid, a connecting groove is processed at the bottom of the jaw main body 1, a first connecting hole 11 and a second connecting hole 12 are respectively processed at two sides of the connecting groove, the clamping block 2 is arranged at the upper part of the outer wall of one side of the jaw main body 1 where the second connecting hole 12 is processed, and the clamping block 2 is fixedly connected with the jaw main body 1.
The embodiment provides an auxiliary jaw of a clamp for processing a steam turbine blade steam passage, and the auxiliary jaw is additionally arranged on a conventional clamp main body, wherein each auxiliary jaw is arranged on one side jaw of the conventional clamp body, the effective clamping range of the clamp is enlarged under the condition of not changing the clamping strength of the clamp, the problem of frequent clamp replacement caused by inconsistent depths of thimble holes is effectively solved, the production efficiency and the product quality are improved, the operation convenience and safety are improved, the labor intensity of an operator is reduced, the clamp is applied to actual work, the operation is simple and convenient, the product quality is improved, the safety and reliability are realized, the labor intensity of the operator is reduced, and the time and labor are saved.
The second embodiment is as follows: the present embodiment is described with reference to fig. 1, and is further limited to the auxiliary jaws described in the first embodiment, and in the present embodiment, there are two auxiliary jaws, and the two auxiliary jaws are respectively installed on one side jaw of the clamp body, and the side of the two auxiliary jaws where the clamping block 2 is installed is disposed opposite to the side where the clamping block is installed. Other components and connection modes are the same as those of the first embodiment.
In this embodiment, the opposite arrangement of the side of the two auxiliary jaws provided with the clamping block 2 is to ensure the stability of clamping and avoid the deviation of the clamping side.
