A locking component of a pneumatic measuring device

Abstract

The invention relates to the technical field of measuring devices, and discloses a locking assembly of a pneumatic measuring device, which includes a sliding arm, the sliding arm is provided with a bracket, the bracket has a cylinder, the cylinder has a built-in push-pull rod, the push-pull rod is provided with a connecting shaft, and the sliding arm is provided with Rotating shaft, there is a rotating arm on the rotating shaft, the rotating arm is equipped with a measuring head, one end of the sliding arm is connected with the sliding arm, and the other end is connected with the rotating shaft, the transmission chain is bent to the side of the cylinder, and the bending part is provided with a transmission rod, connecting the shaft It is connected with the transmission rod, and the connecting shaft is provided with a brake, and the brake is fixedly connected with a holding rod, and the holding rod is fixed on the sliding arm; the sliding arm is provided with a support block, and the end of the support block contacting the rotating shaft is connected with an airbag. The inside of the airbag is filled with reserved gas; during the self-locking process, the airbag makes the resistance between the top of the pole and the connecting shaft increase smoothly and linearly until the locking is completed, and the airbag makes the use of the measuring device more stable.

Description

technical field [0001] The invention relates to the technical field of measuring devices, more specifically, it relates to a locking assembly of a pneumatic measuring device. Background technique [0002] Pneumatic is to use compressed air as the power source to drive the machine to complete the expansion and contraction or rotation. Pneumatic devices have the advantages of simple structure, light weight, simple installation and maintenance, low pressure level, and safer use than hydraulic systems. [0003] The Chinese utility model patent with the patent notification number CN206504712U discloses a pneumatic measuring assembly and a measuring machine including the pneumatic measuring assembly, which are helpful for automatic measurement of workpiece dimensions. The pneumatic measurement assembly includes a measuring head installed on the main body of the measuring machine and an adjustment mechanism for connecting the main body of the measuring machine with the measuring h...

Problems solved by technology

[0004] When the measuring machine in the above patent is in use, if the gas supply equipment fails or the gas is exhausted, the elastic body will quickly retract, resulting in unstable measurement of the measuring machine, and even damage. The structure can lock the measuring state of the measuring machine when the gas supply equipment is faulty or the gas is exhausted and the elastic body is quickly retracted; however, when locked, the measuring machine will experience the state changes of locked, free, and locked, so that the measuring machine is locked. Oscillation occurs during the process, which greatly affects the accuracy of the measurement data
