Oil seal removal tool

This creation is about an oil seal removal tool.

According to the general oil seal removal tool, the oil seal for removing the inner wall of an object (such as a oil pipe or a bearing) for mechanical maintenance. The body of the conventional oil seal removal tool is mostly long straight rod shape, and one end of the body has a hook portion. The hook portion penetrates the inner wall of the object and hooks the oil seal, and the body is abutted against the end surface of the object as a point, and then swings in a lever manner, so that the hook portion can be removed and removed, and the oil seal disclosed by TWM363369 is removed. The tool belongs to this category.

However, only by swinging the body by a single point, it is easy for the body to smoothly swing with the fulcrum as the axis, and it is easy to cause the body to shift toward one side of the axial direction of the axis, and the hook cannot be accurately Hook the oil seal. In addition, since the body of such a conventional oil seal removal tool needs to be placed against the end surface of the object to form a point, the body needs to be tilted to a horizontal angle to swing in a lever manner, so that when the working environment is narrow, the body That is, it is limited by the environment, and cannot be smoothly tilted to a horizontal angle to form a fulcrum against the object, so that the body cannot be smoothly applied, so that the operation of disassembling the oil seal cannot be performed efficiently, and there is a need for improvement. Disadvantages.

Therefore, it is necessary to provide a novel and progressive oil seal removal tool to solve the above problems.

The main purpose of this creation is to provide an oil seal removal tool that avoids the offset of one side of the body in the axial direction of the shaft, so that the hook cannot accurately hook the oil seal. In addition, the body can smoothly apply force to the body without tilting to a horizontal angle, so that the oil seal can be smoothly removed.

To achieve the above object, the present invention provides an oil seal removal tool comprising a body, a support member and an adjustment device. The body includes a rod body and a grip portion. The rod body is provided with a hook portion away from one end of the grip portion. The radial dimension of the grip portion is greater than the radial dimension of the rod body. The support member is slidably disposed on the rod body and is provided with two abutting arms extending from opposite sides of the rod body. The adjusting device is disposed on at least one of the rod body and the support member to selectively fix the support member to the rod body.

The structural features of the present invention and the intended effects thereof will be described below by way of a preferred embodiment, but are not intended to limit the scope of the present invention.

Referring to FIGS. 1 through 4, there is shown a preferred embodiment of the present invention. The oil seal 91 removal tool of the present invention comprises a body 1, a support member 4 and an adjustment device 5.

The body 1 includes a rod body 2 and a grip portion 3, and a rod portion 21 is disposed away from one end of the grip portion 3, and the radial dimension of the grip portion 3 is larger than the rod body. The radial dimension of 2 is convenient for the hand to hold the grip portion 3 to apply force.

The support member 4 is slidably disposed on the rod body 2 and is provided with two anti-arms 41 extending from opposite sides of the rod body 2 .

The adjusting device 5 is disposed on at least one of the rod body 2 and the support member 4 to selectively fix the support member 4 to the rod body 2.

As shown in FIG. 5, in the actual operation, the two anti-arms 41 are provided to abut against an end surface of a oil pipe 9 (which may also be a camshaft in other embodiments), and the hook portion 21 is for hooking the oil pipe 9 One of the oil seals 91 is swayed downward by the user's hand to operate the grip portion 3 so that the hook portion 21 swings upward relative to the grip portion 3, and the hook portion 21 can detach the oil seal 91. Preferably, the two resisting arms 41 are cylindrical, so that the body 1 swings with the two resisting arms 41 as a fulcrum. The two resisting arms 41 of the supporting member 4 abut against the end surface of the oil pipe 9, and the two resisting arms 41 are provided as a fulcrum when the body 1 is swung, so that the body 1 is less inclined to swing. The direction of the heart 6 is offset, so that the hook portion 21 cannot accurately hook the oil seal 91. It is worth mentioning that the structural features of the two arm 41 extending toward the radial sides of the rod body 2 can additionally make the body 1 unnecessary. Tilting to a horizontal angle, the two resisting arms 41 abut against the end surface of the oil pipe 9 to form a fulcrum, so that the grip portion 3 of the body 1 can be biased so that the hook portion 21 can swing like a lever, so The oil seal 91 is successfully removed.

The radial dimension of the hook portion 21 is smaller than the radial dimension of the rod body 2, so that it is more convenient to extend into the oil pipe 9 without being interfered.

Specifically, the support member 4 is provided with a set of perforations 42 disposed on the rod body 2. It is worth mentioning that, since the radial dimension of the grip portion 3 is greater than the radial dimension of the rod body 2, when When the support member 4 is free to slide relative to the rod body 2, the grip portion 3 can abut against the support member 4 to prevent the support member 4 from being detached from the body 1 from the grip portion 3.

Further, the adjusting device 5 includes a first card portion 51 disposed on the rod body 2 and a second card portion 52 disposed on the support member 4, the first card portion 51 and the second card portion 52. Can be selectively snapped. Preferably, one of the first card portion 51 and the second card portion 52 is a lock, and the other is a plurality of card slots. In the embodiment, the second card portion 52 is a lock. The first card portion 51 is a plurality of the card slots. The rotation of the lock member can control the lock card to abut the card slot, and the user can adjust the depth of the oil seal 91 according to the depth of the oil pipe 91. The position of the support 4 relative to the body 1.

In the embodiment, the rod body 2 is provided with a curved section 22, and the bending direction of the curved section 22 is opposite to the bending direction of the hook portion 21, so that the hook portion 21 can easily protrude into the oil pipe 9, the first The two-card portion 52 is disposed between the curved portion 22 and the hook portion 21.

Preferably, the grip portion 3 is a rubber grip or a plastic grip for improving the comfort of the grip. The rod 2 is a metal rod and the support member 4 is a metal member to have a comparison. High structural strength.

Preferably, the hook portion 21 has a tip end 211 having a slope 212, and the slope direction of the slope 212 is opposite to the bending direction of the hook portion 21 to facilitate hooking of the oil seal 91.

In summary, the present oil seal removal tool, by the two abutting arms of the support member abutting against the end surface of the oil pipe, the two arm members are provided as a fulcrum when the body swings, so that the body is less inclined One of the axes is offset, causing the hook to fail to accurately catch the oil seal.

Moreover, the structural feature of the two anti-arms extending toward the radial sides of the rod body can further prevent the body from tilting to a horizontal angle, and the two anti-arms can form a fulcrum against the end surface of the oil pipe, that is, the body can be The grip portion applies a force so that the hook portion can swing like a lever.
