Abstract

The utility model belongs to the field of helicopter engine throttle adjustment, relates to a set of fixing device for guaranteeing the level of bearings/fork lugs with handles at two ends of elastic pull rods with different lengths and different specifications in fixed force, and particularly relates to a universal fixing device for guaranteeing the level of the elastic pull rods in fixed force. The device comprises a base and a bolt; the base is provided with a mounting hole of the bolt, the middle part of the bolt is provided with a disc stop block, two sides of the disc stop block are provided with bolt rods, one bolt rod is arranged in the mounting hole on the base, and the other bolt rod is used for fixing a single lug of the part body; the two universal fixing devices are connected to the two ends of the part body, so that the fixed length and fixed force of the part body are fixed, and the position level of the part body is ensured. The principle that two points are used for determining a straight line can meet the requirement that the rod body and the bearing/fork lug with the handle are stable and fixed when the elastic pull rod is subjected to fixed force after fixed length, the parallelism of the bearing/fork lug with the handle is guaranteed, and meanwhile the bearing/fork lug with the handle is prevented from rotating in the fixed force process.

Description

Universal fixing device for guaranteeing fixed force and time level of elastic pull rod

Technical Field

The utility model belongs to the field of helicopter engine throttle adjustment, relates to a set of fixing device for guaranteeing the level of bearings/fork lugs with handles at two ends of elastic pull rods with different lengths and different specifications in fixed force, and particularly relates to a universal fixing device for guaranteeing the level of the elastic pull rods in fixed force.

Background

The engine throttle adjustment of helicopter, in order to guarantee that the system is normal, accord with the designing requirement, need adjust elastic pull rod length when the installation, carry out fixed length fastening to elastic pull rod, by the manual adjustment of workman guarantee elastic pull rod both ends tape shank bearing fork ear level in the fastening process, tape shank bearing fork ear is easy to rotate when deciding the power, lead to need repeatedly adjusting the power, and different pull rod size is different moreover, tape shank bearing fork ear hole diameter is different, and it is complicated difficult to keep to design the frock of matching. Through technical innovation, a set of fixing device for guaranteeing the level of the bearings/fork lugs with handles at the two ends of the elastic pull rod is designed, and the fixing device is easy to operate and convenient to apply.

Disclosure of Invention

Technical proposal

A universal fixing device for ensuring the constant force level of an elastic pull rod comprises a base 2 and a bolt 1; the base 2 is provided with a mounting hole of the bolt 1, the middle part of the bolt 1 is provided with a circular block, two sides of the circular block are provided with bolt rods, one bolt rod is arranged in the mounting hole of the base 2, and the other bolt rod is used for single-lug fixing of the part body; the two universal fixing devices are connected to the two ends of the part body, so that the fixed length and fixed force of the part body are fixed, and the position level of the part body is ensured.

The bolt 1 is used for being fixed with a single lug of the part body, and the diameters of bolt rods are mutually matched according to the diameters of the single lug.

The base 2 is of a conical structure;

the bottom of the base 2 is provided with a sucker. The friction force is increased, and the position displacement of the tool in operation is prevented.

The base 2 is made of Q235 steel or 45# steel.

The two general fixing devices are guaranteed to be consistent in height, and the position level of the part body can be guaranteed.

Technical effects

The utility model provides a set of universal fixing device for ensuring the level of a bearing/fork lug with a handle at two ends when an elastic pull rod is stressed, which skillfully clamps a surface, converts the surface fixing into point positioning and solves the problems that the pull rod is different in size and the aperture of the bearing/fork lug with the handle is different by utilizing a set of tool. The principle that two points are used for determining a straight line can meet the requirement that the rod body and the bearing/fork lug with the handle are stable and fixed when the elastic pull rod is subjected to fixed force after fixed length, the parallelism of the bearing/fork lug with the handle is guaranteed, and meanwhile the bearing/fork lug with the handle is prevented from rotating in the fixed force process.
