Description

Technical Field

[0001] The utility model relates to the technical field of mechanical tooling, in particular to a hydraulic cylinder assembly tooling. Background Art

[0002] Hydraulic cylinder, also known as hydraulic oil cylinder, is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion or swinging motion. It is widely used in the hydraulic systems of various machines. It is mainly composed of a cylinder barrel and a piston rod.

[0003] As an important supporting component, the hydraulic cylinder has an increasing variety and output with the development of the construction machinery industry. The original assembly equipment and assembly methods are far from meeting the market demand for product quality and quantity. During the assembly process of the hydraulic cylinder, the rapid center line alignment of the cylinder barrel and piston rod assembly is the key and difficulty to ensure the sealing performance of the hydraulic cylinder and improve production efficiency.

[0004] It has been found in actual use that the hydraulic cylinder assembly has the following deficiencies:

[0005] When assembling the hydraulic cylinder assembly and installing the piston rod assembly into the cylinder body, the cylinder body needs to be placed on a workbench, the piston rod is hoisted by a crane to install the rod assembly into the cylinder body, and the fixing bolts are installed and tightened. In this assembly method, the piston rod will also shake during hoisting due to different hoisting positions, resulting in the need to manually align the piston rod and the cylinder body, which not only slows down the assembly and has low production efficiency, but also easily affects the sealing performance of the hydraulic cylinder;

[0006] In addition, when inserting the piston rod, the piston rod is directly squeezed downward into the cylinder body. Since the piston rod is cylindrical and has a small cross-sectional area, it is easy to be misaligned and skewed when inserted manually, causing the piston rod to poke into the cylinder body. The piston rod is bent, causing the piston rod bushing and dust ring to be pressed into the support sleeve and damaged, reducing the yield rate of hydraulic cylinder assembly;

[0007] Therefore, the present application provides a hydraulic cylinder assembly tool to meet the needs. Utility Model Content

[0008] The utility model aims to solve the problems existing in the above-mentioned background technology and proposes a hydraulic cylinder assembly tool.

[0012] Preferably, the feeding trough extends through the cabinet to one end of the cabinet, and the feeding trough is connected to the assembly trough, and the observation port is connected to the assembly trough.

[0013] Preferably, a slide groove is provided at the bottom of the feeding trough, and the placement rack is movably connected to the cabinet through the slide groove.

[0014] Preferably, the material guiding platform is in a trapezoidal shape, the slope of the material guiding platform is 60°, and the slope surface of the material guiding platform is connected to the docking groove.

[0015] Preferably, the docking groove is cylindrical in shape, and the docking tube is installed at the bottom of the docking groove, and the docking tube is truncated cone-shaped.

[0016] Preferably, the docking groove is communicated with the assembly groove, and the docking tube extends vertically downward to the inner upper end of the assembly groove.

[0017] Preferably, the mounting seat and the electric telescopic rod are located directly above the docking groove, and the cushion block is in the shape of a truncated cone, the limiting seat is in the shape of a conical cylinder, and both the cushion block and the limiting seat are made of rubber material.

[0018] Compared with the prior art, the utility model has at least the following beneficial effects:

[0019] 1. Place the piston rod assembly to be assembled directly into the storage box from the feeding port. The piston rod assembly is inserted downward through the guide table to collide with the inner wall of the docking groove, and then vertically inserted into the docking groove, so that the piston rod assembly quickly becomes a vertical state. The cylindrical docking groove can match the shape of the piston rod assembly. Through the truncated cone-shaped docking tube, the diameter of the docking tube gradually shrinks, which can continuously regularize the piston rod assembly so that the piston rod assembly remains in a vertical state when inserted downward. The piston rod assembly is inserted downward from the docking groove through the docking tube into the cylinder barrel of the hydraulic cylinder in the assembly groove to complete alignment, which can effectively improve the sealing performance and production efficiency of the hydraulic cylinder;

[0020] 2. After the piston rod assembly and the cylinder barrel of the hydraulic cylinder are aligned, the electric telescopic rod in the mounting seat extends the output shaft downward, and the output shaft drives the cushion block and the limit seat to move downward and press on the top of the piston rod assembly, so that the piston rod assembly moves into the cylinder barrel of the hydraulic cylinder, and the piston rod assembly is horizontally inserted into the cylinder barrel to complete the assembly. During the movement, the conical limit seat gradually retracts the piston rod assembly into the cylinder barrel. Since the piston rod assembly is cylindrical, the limit seat with a gradually shrinking diameter can clamp the rod body of the piston rod and wrap around the outer end of the piston rod for precise positioning, thereby avoiding the piston rod from tilting and poking into the cylinder barrel during assembly and pressing, causing damage to the cylinder barrel, and can improve the yield rate of hydraulic cylinder assembly.
