Abstract
The utility model discloses a dismounting device for sleeve pipes, which is mainly composed of a base, an oil tank, two hydraulic oil cylinders, and a draw rod, wherein, a through hole is arranged between the two hydraulic oil cylinders on the base, and a rocker arm assembly and an oil return lifting control switch for the hydraulic oil cylinders are also arranged on the base; an expanded push rod, a three-jaw cutting sleeve, a chuck, and opening pipe slips are arranged on the draw rod. The dismounting device for sleeve pipes has the advantages of labor saving and high efficiency of dismounting the sleeve pipes. When the sleeve pipes are dismounted, only one person is enough for the operation, and parts and components can not be damaged. The dismounting device for sleeve pipes is suitable for dismounting the sleeve pipes of various automobile earth axes. In addition, the dismounting device for sleeve pipes is free from place limitation. Even if loaded automobiles, the dismounting work can also be completed at the original place.
Description
The utility model relates to a kind of inserting or withdrawing sleeves device of dismantling automobile chassis ground pipe spreader, belongs to motor vehicle repair instrument field.
At present, when repairing automobile in the prior art, for dismounting automobile chassis ground pipe spreader, common way is manually to adopt sledgehammer to beat, and the method that this employing sledgehammer beats is not only required great effort and be time-consuming, but also damages automobile parts in addition easily, and is therefore very unreasonable.
The purpose of this utility model is: provide a kind of laborsaving and high inserting or withdrawing sleeves device of removal efficiency, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: be fixed with fuel tank (2) on the top of base (1), two hydraulic jacks (3) secured in parallel is in the side of base (1), through hole (5) is arranged between last two hydraulic jacks of base (1) (3), Rocker arm assembly (6) is housed on base (1), hydraulic jack oil return lift control switch (7) is housed on base (1), pull bar (4) can pass through through hole (5), expansion push rod (8) is housed on pull bar (4), three-jaw cutting ferrule (9), chuck (10), folding slips (11), folding slips (11) can be contained in the stepped hole (14) of chuck (10), chuck (10) can be resisted against on the axis of the piston (15) of two hydraulic jacks (3), at the two ends of pull bar (4) boss (12) is arranged, the groove (13) of the bar portion that can put into expansion push rod (8) is arranged on boss (12); Expansion push rod (8) is made up of taper sheath and straight-bar, and straight-bar is fixed on the taper sheath.
The utility model compared with prior art has laborsaving and the high advantage of dismounting cover tube efficiency, only needs a people to operate during dismounting, and can not damage other parts when the dismounting sleeve pipe; It is applicable to dismounting various types of automobiles ground pipe spreader, and not limited by the place during use, even loaded vehicle also can be finished dismantlement work on the spot.During use, earlier the utility model is placed on the automobile earth's axis front end that will dismantle, and make the through hole (5) of base (1) lean against earth's axis front end, then pull bar (4) is put into the hole of the earth's axis together with three-jaw cutting ferrule (9) and made three-jaw cutting ferrule (9) arrival point shaft rear end, promote expansion push rod (8), it is swollen three-jaw cutting ferrule (9), three-jaw cutting ferrule (9) promptly may be stuck on the sleeve pipe of the earth's axis like this, at this moment again chuck (10) and folding slips (11) are contained on the pull bar (4), and chuck (10) is resisted against on the axis of the piston (15) of two hydraulic jacks (3), press Rocker arm assembly (6) and can make the axis of the piston (15) of hydraulic jack (3) pass through chuck (10) pushing drawing rod (4), thereby earth's axis inserting or withdrawing sleeves is got off; Rotate gauge tap (7), the oil in the hydraulic jack (3) is got back in the fuel tank (2).
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the vertical view of accompanying drawing 1;
Accompanying drawing 3 is the A-A cut-away view of accompanying drawing 1;
Accompanying drawing 4 is expansion push rod of the present utility model (a 8) structural representation.
Embodiment of the present utility model: base (1), fuel tank (2), two hydraulic jacks (3), it is toughness No. 45 steel making preferably that pull bar (4) all adopts intensity, pull bar (4) preferably carries out modified or surface hardening heat treatment, fuel tank (2) is fixed on the top of base (1), and with the side of two hydraulic jacks (3) secured in parallel in base (1), between last two hydraulic jacks of base (1) (3), open one directly through the through hole (5) more bigger than three-jaw cutting ferrule (9), on base (1), load onto Rocker arm assembly (6) and gauge tap (7), on pull bar (4), load onto expansion push rod (8), three-jaw cutting ferrule (9), chuck (10), folding slips (11), when making chuck (10), folding slips (11) can be contained in its stepped hole (14), and make on its axis of the piston (15) that can be resisted against two hydraulic jacks (3), produce boss (12) at the two ends of pull bar (4), on boss (12), open the groove (13) that to put into the straight-bar of expansion push rod (8), be fixed on a straight-bar and promptly make expansion push rod (8) on the taper sheath.
