Description

Technical Field

[0001] The utility model relates to the technical field of oil end cover disassembly, in particular to an oil end cover disassembly tool. Background Art

[0002] The oil end cap refers to a container or component used to seal liquids such as lubricating oil or hydraulic oil. It is usually installed on the top of the cylinder to seal the liquid in the cylinder.

[0003] When assembling the oil end cap, the side threads are screwed into the oil cylinder by rotating. If the rotation is excessive and too much torque is used, the oil cylinder cap will be assembled very firmly. When assembling the oil end cap, sealants or sealing gaskets are usually used at the joints to ensure the sealing, but the sealants are easily solidified after being exposed to the environment for a long time, making the adhesion between the oil end cap and the adjacent parts more firm. When the oil end cap is used for a long time, the side threads are prone to rust or corrosion, making the threads rougher and the oil end cap over-tightened. These common situations will make it very difficult to rotate the oil end cap when removing it. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 2 As shown, the utility model provides an embodiment of an oil end cover disassembly tool, which is suitable for an oil cylinder. The oil cylinder is threadedly connected with an oil end cover 1, and the oil end cover 1 is provided with a positioning hole 11.

[0022] Specifically, Figure 1-Figure 3 As shown, the oil end cover disassembly tool comprises: a wrench 2, the wrench 2 is provided with a handle 21, a positioning portion 22 and a connecting portion 23 are extended from one end of the handle 21, the longer portion is the positioning portion 22, the shorter portion is the connecting portion 23, and the connecting portion 23 is rotatably connected to a rotating portion 24.

[0023] Among them, Figure 4 As shown, both the positioning portion 22 and the rotating portion 24 are provided with a pinhole 25 , and the inner diameter of the pinhole 25 is equal to that of the positioning hole 11 .

[0024] Further, such as Figure 3-Figure 4 As shown, the positioning portion 22 and the rotating portion 24 are connected to the positioning pin 3 , and the wrench 2 and the oil end cover 1 are fixed by the positioning pin 3 .

[0025] Specifically, the positioning pin 3 includes a pin portion 31, which passes through the needle hole 25 and extends into the positioning hole 11. A fixing portion 32 is arranged on the top of the pin portion 31. The outer diameter of the pin portion 31 is equal to the inner diameter of the needle hole 25, so that the pin portion 31 is not prone to shaking when inserted into the needle hole 25 and the positioning hole 11. The outer diameter of the fixing portion 32 is larger than the outer diameter of the pin portion 31, which facilitates the installation of the positioning pin 3.

[0026] In this embodiment, the rotating part 24 is first rotated to align the positioning part 22 with the pinhole 25 on the rotating part 24 with the positioning hole 11, and the needle parts 31 of the two positioning pins 3 are passed through the pinhole 25 and inserted into the positioning hole 11, so that the wrench 2 and the oil end cover 1 are fixed to each other. The operator holds the oil cylinder with one hand and holds the handle 21 on the wrench 2 with the other hand and rotates it. The handle 21 serves as a labor-saving lever, and cooperates with the limit of the two positioning pins 3 to more easily drive the oil end cover 1 to rotate. During the rotation process, the side threads of the oil end cover 1 gradually disengage from the oil cylinder, and the oil end cover 1 is completely removed, making the removal of the oil end cover 1 simpler and more convenient, while saving effort and being easier to operate. The operator's hands do not touch the oil end cover 1 and are far away from the oil end cover 1, so they are not easily injured and are safer.

[0027] In another embodiment, the pin portion 31 of the positioning pin 3 is welded in the pin hole 25, and the positioning pin 3 and the wrench 2 form an integrated structure, so that the positioning pin 3 is not easy to be lost. When removing the oil end cover 1, it is only necessary to align the pin portion 31 with the positioning hole 11, knock the fixing portion 32 to make the pin portion 31 embed into the positioning hole 11, and turn the handle 21 to make the side thread of the oil end cover 1 gradually disengage from the oil cylinder during the rotation process until the oil end cover 1 is completely removed.

[0028] Working principle: first rotate the rotating part 24 to align the positioning part 22 with the pinhole 25 on the rotating part 24 with the positioning hole 11, pass the needle parts 31 of the two positioning pins 3 through the pinhole 25, and insert them into the positioning hole 11, so that the wrench 2 and the oil end cover 1 are fixed to each other. The operator holds the oil cylinder with one hand and holds the handle 21 on the wrench 2 with the other hand and rotates it. The handle 21 serves as a labor-saving lever, and cooperates with the limit of the two positioning pins 3 to make it easier to drive the oil end cover 1 to rotate. During the rotation process, the side threads of the oil end cover 1 gradually disengage from the oil cylinder until the oil end cover 1 is completely removed.

[0029] In summary, although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
