Abstract
The invention relates to a Du bushing disassembling tool. An outer support type disassembling puller can be formed by using symmetrical connecting rod slider mechanisms and a spiral ejector rod. The disassembling puller comprises a support body adopting a symmetrical structure, two identical outer support rod components, four identical diameter regulating rod pieces, a spiral ejector rod and a slider rod component, wherein ratchets are welded at the bottom ends of the outer support rod components so as to increase friction with a bushing, the middles of the outer support rod components are connected with the diameter regulating rod pieces so as to form a rotating pair, and the top ends of the outer support rod components are connected with the support body so as to form a rotating pair; a nut welded at the top end of the slider rod component can change screw rotation into reciprocating pull movement with the spiral ejector rod, the middle of the slider rod component can freely move in a hole in the support body, and a bolt welded at the bottom end of the slider rod component can be connected with the diameter regulating rod pieces so as to form an end rotating pair; and all the rotating pairs are realized by bolt connection. The Du bushing disassembling tool can rapidly finish the disassembling operation of various dimensions of DU bushings, and meanwhile, has the characteristics of being simple in structure, easy to manufacture, simple to operate, wide in applications and the like.
Description
Technical field
The present invention relates to the DU bushing dismounting instrument coordinated with pump shaft in a kind of pumping cylinder body opening, utilize symmetrical linkage rod slide block mechanism and spiral ejection pin can form a kind of outer support formula disassembling puller.
Background technology
Current gear pump mostly is technological improvement version, increases DU lining minimizing end face and reveal between pump shaft and cylinder body, when pump maintenance or maintenance, when DU liner wear is serious or damage then needs to carry out dismounting and change.But between DU lining and lining cylinder body be interference fit, dismounting is quite not easy, fragment takes out after DU lining failure by the instruments such as usual use hammer, chisel, scraper again, and the method wastes time and energy, and uses hammer, chisel process easily to cause damage to other parts.
Summary of the invention
The object of this invention is to provide a kind of disassembling puller directly dismantling taking-up DU lining, utilize symmetrical linkage rod slide block mechanism and spiral ejection pin can form a kind of outer support formula disassembling puller.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of DU bushing dismounting instrument, comprises bolt, the nut of identical path transfer bar sheet 2, spiral ejection pin, 4, the slide block rod member 5 of the identical outer strut member 1, four of supporter 3, two with symmetrical structure and several dimensions.Wherein said outer strut member 1 end welding-on ratchet can increase to connect with path transfer bar sheet 2 with bushing friction, middle part and form revolute pair, top and connect with supporter 3 and form revolute pair, with spiral ejection pin 4, described slide block rod member 5 top welding-on nut can carry out that change helical rotation is reciprocal drawing campaign, middle part can move freely in supporter 3, end welding-on stud can connect with path transfer bar sheet 2 and forms one end revolute pair, and described revolute pair is bolt-connection and realizes.
The invention has the beneficial effects as follows: the present invention can complete the field-strip of plurality of specifications DU lining fast to there is structure simultaneously simple, make easy, easy to operate, etc. feature, avoid causing damage to other parts, time saving and energy saving, there is broad applicability.
Accompanying drawing explanation
Fig. 1 is that a kind of DU bushing dismounting draws horse schematic diagram.
Detailed description of the invention
1 the specific embodiment of the present invention is described by reference to the accompanying drawings.As shown in Figure 1, DU bushing dismounting instrument involved in the present invention, comprises bolt, the nut of identical path transfer bar sheet 2, spiral ejection pin, 4, the slide block rod member 5 of the identical outer strut member 1, four of supporter 3, two with symmetrical structure and several dimensions.Wherein said outer strut member 1 end welding-on ratchet can increase to connect with path transfer bar sheet 2 with bushing friction, middle part and form revolute pair, top and connect with supporter 3 and form revolute pair, with spiral ejection pin 4, described slide block rod member 5 top welding-on nut can carry out that change helical rotation is reciprocal drawing campaign, middle part can move freely in supporter 3, end welding-on stud can connect with path transfer bar sheet 2 and forms one end revolute pair, and described revolute pair is bolt-connection and realizes.
The path transfer bar sheet 2 that involved in the present invention two identical outer strut member 1, four are identical and slide block rod member 5 can form two linkage rod slide block mechanisms to symmetry, when drawing slide block rod member 5, two identical outer strut member 1 support can make end ratchet stretching DU lining outward.Monkey wrench or opening double offset ring spanner can be used to turn by slide block rod member 5 and the thread connection of spiral ejection pin 4, change rotary motion is linear reciprocating motion, thus DU lining can be pulled out, and move to be formed with above-mentioned linkage rod slide block mechanism and link, what DU lining can be made while pulling outward to support is tighter.
Claims (2)
1. a DU bushing dismounting instrument, is characterized in that: the bolt, the nut that comprise identical path transfer bar sheet 2, spiral ejection pin, 4, the slide block rod member 5 of the identical outer strut member 1, four of supporter 3, two with symmetrical structure and several dimensions; Wherein said outer strut member 1 end welding-on ratchet can increase to connect with path transfer bar sheet 2 with bushing friction, middle part and form revolute pair, top and connect with supporter 3 and form revolute pair, with spiral ejection pin 4, described slide block rod member 5 top welding-on nut can carry out that change helical rotation is reciprocal drawing campaign, middle part can move freely in supporter 3 hole, end welding-on stud can connect with path transfer bar sheet 2 and forms one end revolute pair, and described revolute pair is bolt-connection and realizes.
2. a kind of DU bushing dismounting instrument according to claims 1, is characterized in that: two identical outer strut member 1 are symmetrically distributed in supporter 3 the right and left; Path transfer bar sheet 2 is symmetrically distributed in slide block rod member 5 both sides, and needs quantification to be two or four according to intensity.
