Description

Frock clamp of airtight test Technical Field The utility model relates to an airtight test, in particular to a fixture for the airtight test. Background For the pipe fitting for connecting two sections of pipes in a pipeline, two ends are generally stepped, and the middle part is small and two ends are large. For pipe elements, tightness is an important parameter, and is generally detected by means of spot inspection. Because the pipe fitting rolls easily, a tool clamp is generally required to clamp and fix the pipe fitting when the air tightness is tested. At present, a combination of a bench vice and a linear module is generally used as a fixture, and after the bench vice clamps and fixes a pipe fitting, the linear module drives the bench vice and the pipe fitting to move together, so that a pipe orifice and a plug of the pipe fitting are sealed. Disclosure of utility model The application provides a tooling fixture for an airtight test, which can solve the problems that the existing tooling fixture is complicated to operate and has low efficiency. The application provides a fixture for airtight test, which comprises: The frame body is concave and comprises a horizontal plate body and two vertical plate bodies opposite to each other in the first direction; The top surface of the mounting seat is provided with a stepped half hole which is used for placing the stepped end part of the pipe fitting; The piston rod is fixedly connected with a plug and is used for plugging/loosening a pipe orifice at the corresponding end of the pipe fitting; The second cylinder is fixedly connected with the other vertical plate body, the piston rod is fixedly connected with a plug for plugging/loosening a pipe orifice at the corresponding end of the pipe fitting, and the piston rod is also provided with a mounting position for mounting the measuring head. In some embodiments, both of the mounting bases can be adjusted in a fixed position on the horizontal plate along the first direction. In some embodiments, the mounting base comprises a base body part for connecting with the horizontal plate body, a first part for setting a larger part in the half hole, and a second part for setting a smaller part in the half hole, wherein the second part is connected with the first part and the base body part. In some embodiments, the air-conditioning device further comprises at least one of a first air cylinder which is a double-acting air cylinder, an air path penetrates through two ends of a piston rod, and a second air cylinder which is a double-acting air cylinder, wherein the piston rod is provided with a wire slot communicated with the installation position. In some embodiments, the outer edge of the plug is beveled. In some embodiments, the horizontal plate body has two convex grooves corresponding to each mounting seat, a nut limited to rotate is arranged at the wider part of each convex groove, two protrusions entering the narrower part of each convex groove are arranged on the bottom surface of each mounting seat, and each mounting seat is also provided with a bolt matched with the nut in a penetrating manner. In summary, in the application, a fixture for airtight test includes a frame, two mounting seats, a first cylinder and a second cylinder.
