Abstract
A quick installation tool for a piston ring is applied to installing a piston with the piston ring into a cylinder body. A rectangular thin steel plate is adopted to manufacture a circular clamping belt, and gaps of 10-30 mm are arranged at the distance between two ends of the circular clamping belt; 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. The effect is as follows: the piston and the piston ring can be conveniently and quickly installed, and damage to the outer surface of the piston or the inner wall of the cylinder body is reduced.
Description
Technical field
The utility model relates to machinery assembling and maintenance technique field, and particularly a kind of erecting tools of piston is a kind of specific purpose tool of being convenient to install the piston that has piston ring.
Background technology
At present, piston is the common parts in the current power-equipment, directly contacts with inner surface of cylinder block for preventing piston, and some roads piston ring is installed on the common piston.Piston ring plays to support sets upright piston action, and piston ring also plays sealing function.Internal diameter at free state lower piston ring is bigger than piston ring groove external diameter; The external diameter of piston ring is bigger than cylinder diameter.For the higher power cylinder body of portion temperature, piston ring material is harder relatively.Consult Fig. 1.Relatively more difficult when in cylinder body, the piston 7 that has piston ring 8 being installed.Usually the piston ring 8 of need firmly extruding, the external diameter that makes piston ring 8 is less than cylinder body 6 internal diameters, and piston ring 8 just can enter in the cylinder body 6, and is single hard, injures the inwall of piston 7 outer surfaces or damage cylinder body 6 easily.
The utility model content
The purpose of this utility model is: a kind of piston ring Fast Installation instrument is provided, can makes things convenient for Fast Installation piston and piston ring, reduce the damage to outer surface of piston or inboard wall of cylinder block.
The technical solution adopted in the utility model is: piston ring Fast Installation instrument, mainly form by cassette tape, hook, supporting base, wrenching bar and clasp, it is characterized in that: adopt the cuboid sheet metal to make the annular cassette tape, there is the breach of 10～30mm at annular cassette tape two ends; On an end outer wall of annular cassette tape, be fixed with hook; Be fixed with two supporting bases on the other end outer wall of annular cassette tape, two supporting bases are parallel to each other; Between two supporting bases, wrenching bar is arranged, wrenching bar is connected on two supporting bases by bearing pin; Be connected with a clasp at the middle part of wrenching bar.Cassette tape is enclosed within on the outer wall of piston ring; Move and rotate up wrenching bar, clasp can hang on the hook; Wrenching bar is gone back to downwards and compresses, and clasp drives hook, and hook furthers the two ends of cassette tape, makes annular cassette tape two ends apart from shortening, and the internal diameter that promptly blocks the annular cassette tape dwindles.The annular cassette tape is with the piston ring reduced diameter on the piston, and the piston ring reduced diameter can together push the piston that has piston ring in the cylinder body smoothly.
Described cassette tape should wrap up all piston rings on the piston, so the width of cassette tape 1 is between 30～80mm.The thickness of cassette tape is between 1～2mm.
The beneficial effects of the utility model: the utility model piston ring Fast Installation instrument, can make things convenient for Fast Installation piston and piston ring, reduce damage to outer surface of piston or inboard wall of cylinder block.Simple in structure, to make easily, cost is low, has wide practical use in the maintenance of Large Piston and in installing.
Description of drawings
Fig. 1 is the position view before cylinder body, piston and piston ring are installed.
Fig. 2 is the utility model piston ring Fast Installation tool construction schematic diagram.
Among the figure, 1-cassette tape, 2-hook, 3-supporting base, 4-wrenching bar, 5-clasp, 6-cylinder body, 7-piston, 8-piston ring.
The specific embodiment
Embodiment 1: with a piston ring Fast Installation instrument is example, and the utility model is described in further detail.
Consult Fig. 1.The utility model piston ring Fast Installation instrument mainly is made up of cassette tape 1, hook 2, supporting base 3, wrenching bar 4 and clasp 5.The employing width is 50mm, and thickness is that the cuboid sheet metal of 1.5mm is made annular cassette tape 1, the internal diameter 350mm of annular cassette tape 1.There is the breach of 30mm at annular cassette tape 1 two ends.
On an end outer wall of annular cassette tape 1, be welded with a hook 2; Being welded with 3, two supporting bases 3 of two supporting bases on the other end outer wall of annular cassette tape 1 is parallel to each other.The wrenching bar 4 that between two supporting bases 3, has a steel plate to curve.There is pin shaft hole a end at wrenching bar 4, on two supporting bases 3 pin shaft hole is arranged, and by bearing pin wrenching bar 4 is connected on two supporting bases 3.The clasp 5 that the steel wire that to be connected with a diameter at the middle part of wrenching bar 4 be 5mm curves.
Claims (2)
