Description

Piston mounting tool

Technical Field

The utility model relates to a mechanical assembly and maintenance technical field, in particular to mounting tool of piston.

Background

The piston is a common component in current power equipment, and in order to prevent the piston from directly contacting with the inner surface of the cylinder body, a plurality of piston rings are arranged on the common piston. The piston ring plays a role in supporting and righting the piston, and also plays a role in sealing. The piston ring is an open ring, and the inner diameter of the piston ring is larger than the outer diameter of the piston ring groove in a free state; the outer diameter of the piston ring is larger than the inner diameter of the cylinder body, so that the piston connecting rod group cannot be installed, and therefore a conical cylinder is usually adopted to push the piston connecting rod group slowly.

In the patent application with publication number CN 201907096U, a quick piston ring mounting tool is disclosed, the technical scheme that this utility model adopts is: the clamping band mainly comprises a clamping band, a hook, a supporting seat, a wrench rod and a retaining ring, wherein a rectangular thin steel plate is adopted to manufacture a circular clamping band, and two ends of the circular clamping band are provided with notches of 10-30 mm; a hook is fixed on the outer wall of one end of the circular clamping belt; two supporting seats are fixed on the outer wall of the other end of the circular clamping belt and are parallel to each other; a wrench rod is arranged between the two supporting seats and is connected to the two supporting seats through a pin shaft; the middle part of the wrench rod is connected with a retaining ring. Sleeving the clamping belt on the outer wall of the piston ring; the wrench rod is moved and rotated upwards, and the retaining ring can be hung on the hook; the wrench rod is rotated back downwards and pressed tightly, the buckle ring drives the hook, and the hook draws the two ends of the clamping belt close to shorten the distance between the two ends of the circular clamping belt, namely, the inner diameter of the circular clamping belt is reduced. The ring-shaped clamping belt reduces the outer diameter of the piston ring on the piston, and the piston with the piston ring can be smoothly pushed into the cylinder body together by reducing the outer diameter of the piston ring.

The couple sets up on the cassette tape in this patent application, reduces the snap ring internal diameter of cassette tape through the couple, and application scope is less, and the mounting tool of the same model can only adapt to the piston ring corresponding with it. When the outer diameter of the piston ring is smaller than the snap ring surrounded by the clamping band or larger than the snap ring surrounded by the clamping band, the piston ring cannot be clamped tightly or cannot be clamped.
