Technical Field
The utility model belongs to the maintenance tool field, concretely relates to extracting tool in hydraulic pressure cover.
Background
At present, the situation of taking out a part in a cylindrical sleeve is often met when various devices are maintained, if a bearing outer ring is clamped in the cylindrical sleeve, various split type hydraulic valve front section annular components fall off in the sleeve when being disassembled, certain difficulty is caused for disassembling work under the situations, the part is possibly damaged by brute force, and extra money time is needed to be input when a special tool is used.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a extracting tool in hydraulic pressure cover can be so that the card dies the annular part in the cover can not receive the damage when light takes out, has not only protected and has taken out the undamaged while, has still protected the inner wall of cover.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a detaching tool in a hydraulic sleeve comprises an impact rod, wherein the top of the impact rod is a force application knocking part, the lower part of the impact rod is an impact part, the impact part is a cylinder which can be matched and inserted with an annular component which needs to be taken out, a first groove is formed in the position close to the bottom of the impact part, and a first O-shaped sealing ring is arranged in the first groove.
Furthermore, the impact mechanism also comprises a plurality of impact sleeves with the same inner diameter and different outer diameters, and the impact sleeves are sleeved on the impact part of the impact rod.
Furthermore, a second groove is formed in the outer wall of the impact sleeve, and a second O-shaped sealing ring is arranged in the second groove.
Furthermore, an oil passage is formed in one side of the upper portion of the impact rod, the oil passage penetrates to the bottom of the impact portion along the impact rod, and a one-way valve is arranged in the oil passage.
Furthermore, the bottom of the impact sleeve is provided with an oil way outlet.
Compared with the prior art, the utility model discloses following beneficial effect has: the utility model discloses a be application of force striking portion with the impact bar top, impact bar lower part impact portion, impact portion for can with the annular part cooperation male cylinder that needs take out, set up first recess in the position that is close to impact portion bottom, be provided with first O shape sealing washer in the first recess. Therefore, when the annular component clamped in the cylindrical sleeve is to be taken out, a proper amount of hydraulic oil or lubricating oil needs to be filled into the annular component and the inner bottom of the cylindrical sleeve, then the impact rod with the same inner diameter as the annular component to be taken out is inserted into the cylindrical sleeve to be contacted with the oil surface, finally the impact rod is knocked by a hammer to enter the annular component, the annular component clamped in the cylindrical sleeve is pushed upwards by the oil pressure, the impact rod can be repeatedly taken out on the way of upwards pushing, oil is added into the cylindrical sleeve until the annular component clamped in the cylindrical sleeve is separated from the cylindrical sleeve, the annular component is not damaged when the annular component clamped in the cylindrical sleeve is taken out, and the inner wall of the cylindrical sleeve is also protected.
Drawings
FIG. 1 is a schematic structural view of example 1;
FIG. 2 is a schematic view of the use of example 1;
FIG. 3 is a schematic structural view of example 2;
FIG. 4 is a schematic view showing the structure of an impingement sleeve in example 2;
in the figure: 1. the oil passage comprises an impact rod, a knocking part 2, an impact part 3, a first O-shaped sealing ring 4, an impact sleeve 5, a second O-shaped sealing ring 6, an oil passage 7, a check valve 8, an oil passage outlet 9, a cylindrical sleeve 10 and an annular component 11.
Detailed Description
Referring to fig. 1-2, a hydraulic sleeve inner dismounting tool comprises an impact bar 1, wherein the top of the impact bar 1 is a force application knocking part 2, an impact part 3 is arranged at the lower part of the impact bar 1, the impact part 3 is a cylinder which can be inserted into an annular component 11 to be taken out in a matching way, a first groove is arranged at a position close to the bottom of the impact part 3, and a first O-shaped sealing ring 4 is arranged in the first groove. Therefore, during the use process, hydraulic oil or lubricating oil can be added into the cylindrical sleeve 10, thereafter, the striking part 3 is fittingly inserted into an annular member 11 caught in the cylindrical sleeve 10, and thereafter the striking part 2 is struck with a hammer or the like, the seized annular member 11 is pushed upward by the oil pressure, and if the cylindrical sleeve 10 is short in length, the annular member 11 can be directly pressed out by oil pressure, and if the cylindrical sleeve 10 is long, the impact bar 1 needs to be taken out repeatedly, oil is added into the sleeve until the annular component 11 which is stuck inside is separated from the sleeve, however, it is necessary to ensure that after the bottom of the impact portion 3 has to be in contact with the liquid surface, the first O-ring 4 needs to be in contact with the annular member 11 so that it can achieve a sealing function to prevent the hydraulic oil from overflowing from the gap between the impact portion 3 and the annular member 11 when the knocking is performed.
Example 2
Referring to fig. 3-4, this embodiment is extended based on embodiment 1, so that the present invention has stronger adaptability. Through processing the impact sleeve 5 that the same external diameter of a plurality of internal diameter is different, during the use, can overlap impact sleeve 5 cover and establish on impact portion 3 of impact bar 1, and set up the second recess in impact sleeve 5 outer wall, set up second O shape sealing washer 6 in the second recess, make when meetting annular part 11 that other internal diameters do not use, can be through changing different impact sleeve 5, thereby can carry out the adaptation with annular part 11 and take out, and second O shape sealing washer 6 also can be the same with first O shape sealing washer 4, play sealed effect.
Certainly, can also set up oil duct 7 in 1 upper portion one side of impact rod, oil duct 7 runs through to 3 bottoms of impact portion along impact rod 1, sets up check valve 8 in the oil duct 7, makes the utility model discloses when using, need not to take out impact rod 1 when adding hydraulic oil, only need through to oil duct 7 add hydraulic oil can, it is very convenient to have seted up oil circuit export 9 in impact cover 5 bottoms, make impact cover 5 oil circuit export 9 can be discharged hydraulic oil to cylindrical cover 10 in, convenient and impact rod 1 adaptation.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof.
