Detailed Description

In order that the above objects, features and advantages of the application will be readily understood, a more particular description of the application will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. The present application may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the application, whereby the application is not limited to the specific embodiments disclosed below.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an engine oil seal disassembling tool according to an embodiment of the present application, and the engine oil seal disassembling tool according to an embodiment of the present application includes a gripping assembly 10, a pressing member 20, and an impact member 30. The grabbing assembly 10 is used for grabbing an oil seal, and the pressing piece 20 is used for pressing the engine.

Referring to fig. 1, the grip assembly 10 is provided with a first via 111. The pressing member 20 passes through the first via hole 111 and is connected to and engaged with the wall of the first via hole 111, and the pressing member 20 is provided with an action portion 21. The impact member 30 is sleeved on the pressing member 20, the impact member 30 is located between the acting portion 21 and the gripping assembly 10, and the impact member 30 can move along the axial direction of the pressing member 20 towards the direction close to the acting portion 21 and impact the acting portion 21 to dislocate the oil seal.

According to the engine oil seal dismounting tool, during operation, the pressing piece 20 is pressed against the engine, the oil seal is gripped by the gripping assembly 10, then the impact piece 30 is gripped by hands, the impact piece 30 is moved along the axial direction of the pressing piece 20 towards the direction close to the acting part 21, and the impact piece 30 rapidly impacts the acting part 21 to generate impact force, so that the oil seal is dislocated. Finally, the external force acts on the pressing piece 20, so that the dislocated oil seal can be completely pulled out. Therefore, the oil seal is favorable for being quickly disassembled, the disassembly efficiency is improved, the labor intensity is reduced, the nondestructive disassembly can be realized, and the operation is convenient on the whole vehicle.

In one embodiment, referring to fig. 1 and 2, the impact member 30 is provided with a first opening 32 and a second via hole 31 that are adapted to the pressing member 20. The wall of the second via hole 31 is provided with a second opening 311, and the second via hole 31 communicates with the first opening 32 through the second opening 311. In this way, the impact member 30 of different mass can be replaced according to the diameter of the oil seal so as to better impact the acting portion 21, so that the oil seal is quickly dislocated. When the impact piece 30 is replaced, the pressing piece 20 slides out from the second through hole 31 of the impact piece 30 through the first opening 32, then the impact piece 30 with the diameter matched with the oil seal is selected, and the pressing piece 20 slides into the second through hole 31 through the first opening 32 of the impact piece 30, so that the impact piece 30 can be replaced conveniently, and the replacement efficiency is improved.

Further, referring to fig. 1 and 2, the second via hole 31 is a circular hole. The mouth wall of the first opening 32 includes first and second opposite and spaced mouth walls 321 and 322, respectively, extending from the hole wall of the circular hole toward the outer periphery of the impact member 30 along both ends of the circumference thereof and penetrating the outer periphery of the impact member 30.

The distance between the first port wall 321 and the second port wall 322 is adapted to the diameter of the pressing member 20, so that the pressing member 20 passes into and out of the second via hole 31 through the space between the first port wall 321 and the second port wall 322.

In this embodiment, referring to fig. 2, the first port wall 321 and the second port wall 322 are both planar. Thus being convenient to process. In addition, even if the pressing member 20 slides into the first opening 32 through the second opening 311 during the impact of the impact member 30 on the acting portion 21, the first opening wall 321 and the second opening wall 322 which are planar can also play a role in clamping and limiting the pressing member 20, so as to prevent the impact member 30 from being separated from the pressing member 20 during the impact.

In one embodiment, referring to FIG. 1, the impingement member 30 is provided with at least one handle 33. In operation, the operator holds the handle 33 by hand and moves the impact member 30 in the axial direction of the pressing member 20 in the direction approaching the acting portion 21, and the impact member 30 rapidly hits the acting portion 21 to generate an impact force, so that the oil seal is rapidly dislocated. Therefore, by arranging the handle 33 on the impact member 30, the handle 33 can provide an application point, so that an operator can conveniently drive the impact member 30 to move along the axial direction of the pressing member 20, and the operation convenience is improved.

The pressing member 20 is a screw rod, and the screw rod passes through the threaded hole and is in threaded connection with the threaded hole. The reaction portion 21 is a nut secured to an end of the screw remote from the gripping assembly 10. During operation, after the oil seal is dislocated, a wrench can be used to screw the nut to drive the pressing piece 20 to rotate along the axial direction of the pressing piece 20, so that the grabbing component 10 moves along the axial direction of the pressing piece 20 in a direction away from the oil seal. Since the pressing member 20 presses against the engine to provide a reverse force, the dislocated oil seal can be completely pulled out by driving the holding assembly 10 when the holding assembly 10 moves away from the oil seal.

In this embodiment, the nut is a hexagonal nut, which is not limited thereto.
