Detailed Description
For the purpose of making apparent the objects, technical solutions and advantages of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and examples, it being understood that the specific examples described herein are for illustration only and are not intended to limit the present invention.
Referring to fig. 2, 3 and 4, the invention provides an engine piston connecting rod disassembling tool, which comprises a fixed outer shell 4, a movable inner shell 5, a first piston push rod 6 and a second piston push rod 7;
one end of the fixed housing 4 is of a transversely-placed n-shaped structure with two output heads 41, a semicircular arc edge 42 is arranged between the two output heads 41, and the arc edge 42 can be attached to the outer wall of the crankshaft to achieve the positioning effect.
The movable inner shell 5 is movably mounted in the fixed outer shell 4, and further explained that the movable inner shell 5 can move left and right in the fixed outer shell 4, when the movable inner shell 5 is in a right end state, two output heads on the movable inner shell 5 can extend out of the fixed outer shell 4, the extended movable inner shell 5 can drive the second piston push rod 7 to move, and the second piston push rod 7 pushes the connecting rod 3 to move; when the movable inner shell 5 is in the left end state, the two output heads are retracted into the fixed outer shell 4;
an elastic piece 8 is arranged between the movable inner shell 5 and the fixed outer shell 4 and positioned in the fixed outer shell 4; further, the elastic member 8 is a spring. The movable inner shell 5 can move from an initial left end state to a right end state (at the moment, the elastic piece 8 is stretched) under the action of external force; when the movable inner shell 5 loses the action of external force, the movable inner shell 5 can be restored to the original left end state under the action of the elastic force of the elastic piece 8.
The two output heads of the movable inner shell 5 are respectively provided with a second piston push rod 7, and the other end of the movable inner shell 5 is provided with a first piston push rod 6; when the first piston push rod 6 is pushed into the inner part of the movable inner shell 5, the second piston push rod 7 can extend out from the inner part of the movable inner shell 5; when the first piston push rod 6 is pulled out from the inside of the movable inner shell 5, the second piston push rod 7 is retracted inside the movable inner shell 5.
The piston 71 is installed to the second piston push rod 7 and the first piston push rod 6 are located the inside one end of movable inner shell 5, and be filled with the gas of certain pressure in the movable inner shell 5, this gas is nitrogen gas, and the stability of nitrogen gas is higher, does not have danger after receiving the compression in the twinkling of an eye. The first piston push rod 6 is driven to move by air pressure, and the second piston push rod 7 is driven to move by air pressure.
A positioning component is arranged between the movable inner shell 5 and the first piston push rod 6, and the positioning component can fix the position of the first piston push rod 6 and the movable inner shell 5;
the positioning assembly comprises two groups of ear plates 9 which are mutually corresponding and respectively arranged on the movable inner shell 5 and the first piston push rod 6, a threaded hole 91 is formed in the center of each ear plate 9, and a long rod bolt 10 is screwed in the threaded hole 91; when the first piston push rod 6 and the movable inner shell 5 need to be fastened, the long rod bolt 10 is screwed between the two corresponding lug plates 9; when the fastening between the first piston push rod 6 and the movable inner shell 5 is canceled, the long rod bolt 10 between the first piston push rod 6 and the movable inner shell 5 is detached.
Referring to fig. 4, 5 and 6, in this example, the present tool is in use;
