Clamp for aerospace testing machine

Abstract

The invention discloses a clamp for an aerospace testing machine. The clamp comprises a bottom plate and a mounting plate welded to the outer wall of one side of the bottom plate, a servo motor is connected to the outer wall of the top of the mounting plate through bolts, a sliding groove is formed in the outer wall of the top of the bottom plate in the length direction, and a two-way screw is connected to the inner wall of one side of the sliding groove through a bearing; one end of the two-way screw extends to the outer wall of one side of the bottom plate, one end of the two-way screw is connected with an output shaft of the servo motor through a coupler, two sliding blocks are slidably mounted in the sliding groove, clamping plates are welded to the outer walls of the tops of the two sliding blocks, and supporting structures are arranged on the outer walls of the two ends of the top of the bottom plate. The supporting structure comprises two connecting plates and two fixing plates,and rotating rods are connected to the outer walls of the opposite sides of the two connecting plates through bearings. The clamp is easy and convenient to fix and operate, the clamping plates are prevented from damaging the testing machine, meanwhile, the anti-skid protrusions can prevent the testing machine from sliding off, and the fixing effect is improved.

Description

technical field [0001] The invention relates to the technical field of testing machines, in particular to a clamp for aerospace testing machines. Background technique [0002] Aviation refers to the navigation activities of manned or unmanned aircraft in the earth's atmosphere. Aviation must have the air medium and the lift to overcome the aircraft's own gravity, and most aircraft must also have the power required to generate relative to the air movement. Spaceflight refers to the navigation activities of manned or unmanned spacecraft outside the earth's atmosphere. Also known as space flight or space navigation, the realization of spaceflight must enable the spacecraft to overcome or get rid of the gravitational force of the earth. If it wants to fly out of the solar system, it must also get rid of the gravitational force of the sun. The aircraft launched from the surface of the earth circles the earth, breaks away from the earth and flies out of the solar system The requi...

Problems solved by technology

[0003] When developing an aerospace vehicle, it is necessary to use a testing machine to conduct various tests to ensure the stability and safety of the aerospace vehicle. When using a testing machine for testing, it is necessary to use a clamp to clamp the testing machine. However, The existing clamping device cannot clamp the testing machine very well, and the clamping effect is not good. In addition, the existing clamping device is easy to cause damage to the testing machine and affect the test results of the testing machine
