Problems solved by technology
[0004] In the process of realizing the present invention, the inventor has found that the prior art has at least the following deficiencies: when replacing the Y-shaped sealing ring 4, it is necessary to first assemble the Y-shaped sealing ring 4 in the sealing ring groove of the piston 3, and then replace the piston 3 Push into the cylinder 1, when the piston 3 advances, the flange 5 of the Y-shaped sealing ring 4 will be stuck in the groove 2 at the front end of the cylinder, so that the piston 3 cannot be pushed into the cylinder 1
This method is easy to cause damage to the flange 5 of the sealing ring, which will reduce its service life in the slightest and destroy its sealing effect in severe cases.

Embodiment Construction
[0032] This embodiment is to facilitate the understanding of the present invention without limiting the claims and core content of the present invention in any way.
[0033] Examples such as image 3 As shown, an assembly tool for jacking a hydraulic cylinder piston includes a ring body 7, the outer diameter of the ring body 7 is the same as the inner diameter of the cylinder barrel 1 at the groove 2, and the inner diameter of the ring body 7 is the same as that without the groove The inner diameters of the cylinders 1 at the 2 places are the same, and the width of the ring body 7 is 0.2-0.5 mm smaller than the width of the groove 2. In this example, it is 0.2 mm. The purpose is to reserve the activity space of the ring body 7. The evenly divided first ring block 8, the second ring block 9, and the third ring block 10 are composed of three parts, and the dividing plane between the first ring block 8 and the second ring block 9 Where the plane passes through the center of the ...

The invention discloses an assembly process for the piston of the jacking hydraulic oil cylinder, evenly applying lubricating grease in the groove; assembling the first circular ring block and the second circular ring block in the groove at the front end of the cylinder, Then assemble the third ring block in the groove; push the piston into the cylinder until the Y-shaped sealing ring passes through the groove; pry the gap between the first ring block and the second ring block , the first ring block or the second ring block pushes down the third ring block, and after the third ring block falls off, take out the first ring block and the second ring block; Continue to push the piston into the assembly, the piston can be easily pushed into the oil cylinder for assembly and disassembly, which saves time and labor, and is economical and environmentally friendly. The Y-ring can be replaced quickly to avoid damage to the Y-ring.
Description
[0001] The present invention is a divisional application of the application number 2013107130393, the application date is December 23, 2013, and the invention name is "an assembly tool and assembly process for jacking hydraulic cylinder piston". technical field [0002] The invention relates to a jacking hydraulic oil cylinder, in particular to an assembly process of a jacking hydraulic oil cylinder piston, which belongs to the technical field of construction. Background technique [0003] The tower crane lifting hydraulic cylinder is mainly composed of cylinder 1, piston rod 6, piston 3, cylinder head, cylinder tail, seals, accessories and so on. The seals are vulnerable parts. In the daily repair and maintenance of the oil cylinder, replacing the sealing device is the most common task, and the replacement of the Y-shaped sealing ring 4 is the main task. Such as figure 1 As shown, the inner wall of the front end of the cylinder 1 is provided with a groove 2 for assembling ...
