Description

Technical Field

[0001] The utility model relates to the technical field of oil seal repair, and more specifically, to a tool for repairing an oil seal of a crankshaft of an automobile engine. Background Art

[0002] Oil seal is a common name for general seals, which is simply the seal of lubricating oil. It is a mechanical component used to seal grease, which isolates the parts that need lubrication from the output parts in the transmission parts to prevent the lubricating oil from leaking. After long-term use, the oil seal has the risk of aging, so it is necessary to check and replace the oil seal regularly. When replacing the existing oil seal, the installation is more laborious and the sealing degree of the oil seal installation is required to be high, so sometimes the seal may not be strong enough.

DETAILED DESCRIPTION

[0019] 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.

[0020] like Figures 1 to 5 As shown, the utility model provides a tool for repairing an oil seal of an automobile engine crankshaft, comprising a fixing plate 1, a stud 2 is meshed inside the fixing plate 1, a connecting block 3 is fixedly installed above the stud 2, a rotating column 4 is inserted inside the connecting block 3, a sliding block 5 is fixedly installed on the side of the stud 2 away from the connecting block 3, a pressing plate 7 is sleeved on the surface of the stud 2, a rotating groove 6 is provided inside the pressing plate 7, a screw rod 8 is meshed on the surface of the fixing plate 1, a knob 9 is fixedly installed above the screw rod 8, and a base 10 is fixedly installed at the bottom of the screw rod 8.

[0021] The stud 2 is located above the oil seal 18 and its main function is to adjust the overall height of the pressure plate 7 by engaging with the fixing plate 1. During installation, the oil seal 18 can be pressed to achieve a stable installation effect.

[0022] Among them, a telescopic rod 11 is fixedly installed at the bottom of the fixed plate 1, a spring 12 is sleeved on the surface of the telescopic rod 11, a connecting plate 13 is fixedly installed at the bottom of the spring 12, a mounting hole 14 is opened on the surface of the connecting plate 13, and a drag hook 15 is inserted into the mounting hole 14.

[0023] The main function of the connecting plate 13 is to control the height of the drag hook 15 through the telescopic effect of the telescopic rod 11, so as to facilitate the removal of the oil seal 18 by applying force upward.

[0024] An oil tank 16 is provided at the bottom of the fixing plate 1 , a mounting opening 17 is provided on the surface of the oil tank 16 , and an oil seal 18 is embedded in the mounting opening 17 .

[0025] The oil seal 18 is in the shape of a circular ring, and its main function is to seal the installation opening 17 , thereby preventing the oil inside the oil tank 16 from leaking out.

[0026] There are three sliders 5 , all of which are located inside the rotating groove 6 , and the pressing plate 7 is in a circular ring shape.

[0027] The main function of the three sliders 5 is that when they are driven by the stud 2 to rotate, the three sliders 5 all rotate inside the rotating groove 6. At the same time, the three sliders 5 will drive the pressure plate 7 to press downward, so that the bottom of the pressure plate 7 contacts the oil seal 18, thereby squeezing the oil seal 18 into the interior of the installation port 17.

[0028] There are two screw rods 8 , two knobs 9 and two bases 10 , and the two screw rods 8 , the two knobs 9 and the two bases 10 are respectively located on the left and right sides of the stud 2 .

[0029] The two bases 10 are in contact with the surface of the oil tank 16 , and their main function is to ensure the overall stability of the fixing plate 1 when the oil seal 18 is installed, and to prevent the oil seal 18 from being installed crookedly.

[0030] There are two pull hooks 15 , and both pull hooks 15 are located above the oil seal 18 .

[0031] The main function of the two hooks 15 is to insert the bottom of the hook 15 into the oil seal 18 when the oil seal 18 needs to be disassembled, and then press the connecting plate 13 toward the fixing plate 1 so that the oil seal 18 can be easily pulled out, thereby achieving the effect of convenient disassembly.

[0032] The working principle and use process of this utility model:

[0033] First, the stud 2 is engaged upward from the bottom of the fixing plate 1, so that the connecting block 3 is higher than the surface of the fixing plate 1, and at the same time, the rotating column 4 is inserted into the inside of the connecting block 3 to drive the stud 2 to continue to engage upward;

[0034] At this time, when the oil seal 18 needs to be installed, the knob 9 is first engaged downward to make the bottom of the base 10 contact the surface of the oil seal 18. At this time, the rotating column 4 is rotated to drive the stud 2 to engage with the fixing plate 1. At the same time, the stud 2 will move downward. At this time, the bottom of the pressure plate 7 will contact the surface of the oil seal 18. Continuing to rotate the rotating column 4 will cause the pressure plate 7 to press the oil seal 18 inward, thereby achieving the effect of stably installing the oil seal 18.

[0035] When the oil seal 18 needs to be disassembled, the stud 2 and the connecting block 3 are first disassembled, and then the slider 5 is inserted into the inside of the oil seal 18. At this time, the connecting plate 13 is pressed toward the connecting block 3 so that the oil seal 18 can be directly pulled out, thereby achieving the effect of facilitating the disassembly of the oil seal 18;

[0036] Finally, check whether the installed oil seal 18 is complete to prevent oil leakage.
