Abstract
The utility model relates to an oil cylinder reconditioning instrument, in particular to an appliance for dismounting hydraulic cylinder piston mainly aiming to solve the technical problems of sealing damage easily caused by manual reconditioning and poor sealing effect resulting from uncontrolled screwing force. The utility model provides the following technical proposals: the appliance comprises two movable rods, two movable covers and a cross beam, wherein, the cross beam is a cuboid; the movable covers are nested on the cross beam and can move along the cross beam; the bottoms of the movable covers are fixed with the movable rods; in addition, the middle part of the cross beam is fixed with a sleeve. The special appliance adopts a torque spanner to provide the torque used during dismounting and then transfers the torque to components and parts such as the piston through a connecting device, thereby simplifying the dismounting process.
Description
Technical field: the utility model relates to the oil cylinder service kit, particularly a kind of instrument that is used for the dismounting oil cylinder piston.
Background technology: the general employing of the dismounting of existing oil cylinder beaten parts such as piston, fairlead, it is packed into by force or dismantles.Because the seal request of oil cylinder is relatively stricter, corresponding endoporus and outer round surface are had relatively high expectations.Therefore in assembling,, assembly method do not reach sealing effectiveness and assurance installation quality because reaching to cause bad seals easily and can not control screwing force.
Summary of the invention: the purpose of this utility model provide a kind of can avoid oil cylinder since during dismounting parts such as piston cause the instrument of the dismounting oil cylinder piston of cut.Mainly solve to adopt by hand and cause bad seals easily and can not control the technical problem that screwing force does not reach sealing effectiveness.Needed moment of torsion when this cover specific purpose tool adopts torque spanner that dismounting is provided by the jockey of design, is delivered to parts such as piston then, reaches the purpose of simplifying disassembly process.The technical solution of the utility model is: a kind of instrument that is used for the dismounting oil cylinder piston, comprise two motion bars, two movable sleeves and a crossbeam, described crossbeam is a cuboid, movable sleeve is socketed on the crossbeam and department moves along crossbeam, the movable sleeve bottom is fixed with motion bar, is fixed with a sleeve at the crossbeam middle part.
The beneficial effects of the utility model are, owing on piston end face, have the locating hole of two symmetries in advance, to insert wherein with the motion bar of locating hole diameter coupling, adopt torque spanner to insert sleeve then and move, just can be very easily with the oil cylinder piston dismounting, and can not cause the problem of bad seals, and operate by torque spanner, can fine control screwing force, during assembling, can play good sealing effectiveness.
Description of drawings:
Fig. 1 is the utility model structural representation front view
Fig. 2 is the utility model structural representation left view
Among the figure: 1-motion bar, 2-crossbeam, 3-movable sleeve, 4-sleeve, 5-torque spanner.
The specific embodiment: with reference to Fig. 1,2, this cover specific purpose tool comprises 3, one crossbeams 2 of 1,2 movable sleeve of 2 motion bars, provides torsion by torque spanner.
Crossbeam 2 is a wide 30mm, high 30mm, and the cuboid of long 500mm, movable sleeve 3 is long 25mm, wide 46mm, the cuboid of high 58mm cuts out and the wide contour slot of crossbeam in movable sleeve cuboid central authorities.During use 2 movable sleeves 3 are connected with crossbeam 2, can regulate different spans according to the piston of different size like this, satisfy different assembling demands.Beat the screw thread of M16 at 2 movable sleeves.Motion bar by screw threads for fastening with the fixed distance between 2 movable sleeves, centre distance when guaranteeing dismounting.
The structure of motion bar 1 is a cylinder, and top is the helicitic texture of M16, makes it to be connected with movable sleeve.Dismounting and replacing for ease of motion bar grind two planes on motion bar.And for big torsion can be provided, motion bar is quenched, improve its intensity.Because parts such as motion bar and piston directly link to each other during dismounting.Therefore be easy disassembly, two pilot holes are made a call at corresponding position on piston, according to the size of φ d on these two pilot hole decision motion bars, both can be matched then, carry out dismounting.So neither influence the technology of piston, again can easy disassembly.
Welding one diameter is a 30mm sleeve 4 in crossbeam 2 central authorities, torque spanner 5 can be delivered to corresponding torsion on this cover specific purpose tool by this bolt, when dismounting, size and spacing according to 2 assembly technology holes on the parts such as piston, choose reasonable motion bar 1 carries out the assembling of specific purpose tool according to the distance between these 2 pilot holes then, 30 sleeves 4 with the centre are the center, two movable sleeves 3 are installed on the crossbeam 2, then motion bar 1 is connected on the movable sleeve 3, adjusts the motion bar distance according to the spacing of the technology pilot hole on the piston.Provide moment of torsion by torque spanner 5 then, guarantee installation quality.So just can carry out the dismounting of parts such as piston, this cover specific purpose tool is simple to operate, and assembling is quick, can provide torsion accurately by torque spanner, simplify the disassembly process of parts such as piston, and can reduce because the improper cylinder seal wear problems that causes of dismounting such as pistons.
