Abstract
The utility model relates to a tool for installing a valve guide tube of an internal combustion engine. The tool is characterized in that a positioning device for locking a guide tube and assembly of the internal combustion engine is arranged on the small end 5 of a pull rod 9; the diameter of the small end 5 is less than the internal diameter of the valve guide tube and assembly; the length of the small end 5 is more than the total length of the valve guide tube and assembly and a seat eye of the valve guide tube; threads 4, a screw cap 2 matched with the threads 4, and a pressure disc 3 are arranged on the big end 10 of the pull rod 9. The specific tool is used for installing the valve guide tube of the internal combustion engine. Thus, various abuses generated by knocking with a hammer are avoided, the valve guide tube and the seat eye are not damaged, original sealing performance among a valve seat, the valve guide tube, and the guide tube seat eye is not influenced, and the utility model has the advantages of labor saving, reliability, and high work efficiency.
Description
The utility model relates to a kind of Internal-Combustion Engine Maintenance instrument, especially a kind of engine valve conduit special use instrument of packing into.
For many years, changing valve guide bushing in the maintenance such as motorcycle, automobile is a problem of having a headache very much.Because the catheter block eye on valve guide bushing and the cylinder head is a tight fit, and the valve guide bushing general aspects is more crisp, traditional installation is to knock in hammer, and therefore have following open defect: one, valve guide bushing cracks easily, and valve guide bushing is scrapped; Two, conduit mouth is easily rung burr, influences the insertion of valve stem and slides; Three, because hammer strikes firmly irregularly,, easily cylinder head guide pipe seat eye is pulled, caused oil seepage in cylinder so valve guide bushing just should not put; Even the four catheter block intraoculars of packing into reluctantly are also excessive because of deviation, increased the time of the valve of milling, have in addition also need with the reamer strand, thereby shortened service life of valve and valve seating.Cumbersome when five, installing, effort, work efficiency are low.
The purpose of this utility model is to overcome above defective, a kind of valve guide bushing and catheter block eye of not damaging is provided, do not influence original sealing and valve stem sliding in valve guide bushing between valve and valve seating and valve guide bushing and the catheter block eye, and rapid operation, engine valve conduit special use reliable, that work efficiency the is high instrument of packing into.
The purpose of this utility model is achieved in that a kind of engine valve conduit special use instrument of packing into, comprise pull bar, nut and packing ring, be characterized in: the microcephaly of pull bar is provided with the positioner of locking internal combustion engine conduit and assembly, microcephaly's diameter is less than the internal diameter of valve guide bushing and assembly, and microcephaly's length is longer than the total length of valve guide bushing assembly and valve catheter block eye; Nut and pressure disc that the major part of pull bar is provided with screw thread and matches with it.
Described positioner, can take following structure, comprise: be located at the positioning concave ring on the pull bar microcephaly, the positioning seat that endoporus is tapering and two semicircle cone locator cards that embed between positioning seat endoporus and the pull bar small head external diameter and lock and the adjustment packing ring, positioning seat is big by a lateral aperture of pull bar microcephaly tail end, and the opposite side aperture is little, and the stub end endoporus of location kayser is provided with the protruding circle in the location that matches with positioning concave ring.
Described positioner can also adopt another kind of structure, promptly comprises: the nut that is located at the screw thread on the pull bar microcephaly and matches with it.
Owing to adopt above structure, the utlity model has following advantage: because location of this instrument of employing, one slowly screws nut until valve guide bushing and assembly are entered the fixed position, avoided knocking in the damage that is caused to valve guide bushing and catheter block eye with hammer, guaranteed original sealing between valve and valve seating and valve guide bushing and the catheter block eye effectively, guaranteed that valve stem can insert valve guide bushing flexibly and also slide freely within it.Simultaneously, easy and simple to handle, laborsaving, work efficiency is high, good reliability, be applicable to that the valve guide bushing in the various Internal-Combustion Engine Maintenance is installed, have popularizing value widely.
Fig. 1 is the utility model (adopting the deck positioner) structural representation.
Fig. 2 is the utility model (adopting the screw thread positioner) structural representation.
Fig. 3 is the utility model assembling (use) view.
Referring to Fig. 1, pull bar 9 is an integral body, generally makes of No. 45 carbon steels.The microcephaly 5 of pull bar 9 is provided with the positioner of locking internal combustion engine conduit and assembly, and microcephaly 5 diameter is less than the internal diameter of valve guide bushing and assembly, and microcephaly 5 length is longer than the total length of valve guide bushing and assembly and valve catheter block eye.Nut 2 and pressure disc 3 that the major part 10 of pull bar 9 is provided with screw thread 4 and matches with it.Pressure disc 3 cylindricals are provided with little and the tapering that opposite side is big of a side by microcephaly's 5 one ends of pull bar 9, to match with the valve seating of cylinder head.Be provided with the square toes that to apply mechanically spanner or rectangle 1 at the tail end of the major part 10 of pull bar 9.Be located at the locking internal combustion engine conduit on the microcephaly 5 of pull bar 9 and the positioner of assembly, can adopt following structure: on the microcephaly 5 of pull bar 9, be provided with 1-6 positioning concave ring 6, the phase mutual edge distance of positioning concave ring 6 is generally set several regular sizes according to the length of the catheter block eye of cylinder head and valve guide bushing and assembly is different, positioning seat 7 is enclosed within on the microcephaly 5 of pull bar 9, the endoporus of positioning seat 7 is provided with tapering, side by microcephaly's 5 tail ends is a major part, opposite side is the microcephaly, mainly is installation and the location of being convenient to have the location kayser 8 of same tapering.Two semicircle cone locator card locks 8 embed between positioning seat 7 endoporus and pull bar microcephaly 5 external diameters from positioning seat 7 macropores one side, and the stub end endoporus of location kayser 8 is provided with the protruding circle in the location that matches with positioning concave ring 6.The thickness, quantity of adjusting packing ring 11 leans on the distance plane of pull bar major part 10 one sides between to decide by the plane of pull bar major part 10 1 sides with the valve guide bushing that has packed into pull bar microcephaly 5 according to, positioning seat 7.Referring to Fig. 2, described positioner also can adopt other structures, as: with the nut 15 that the pull bar microcephaly is designed to screw thread 14 and matches with it, its screw thread 14 external diameters are also less than the internal diameter of valve guide bushing and assembly.
Referring to Fig. 3, in the time of need packing valve guide bushing and assembly 12 into, at first microcephaly's 5 ends of pull bar 9 are passed the catheter block eye (not shown) of cylinder head 13, then valve guide bushing and assembly 12 are enclosed within on the microcephaly 5 of pull bar 9, secondly will adjust packing ring 11 and locate deck 7 and be enclosed within on the microcephaly 5, again two location kaysers 8 are packed in the deck 7 of location, stick in the location Baltimore groove 6 on the microcephaly 5 who is located at pull bar 9.Then, pressure disc 3 is enclosed within on the major part 10 of pull bar 9, promptly is pressed on the valve seating (not shown) and at last nut 2 is screwed in.At this moment block the rectangle head 1 of pull bar 9 with instruments such as spanners, with instruments such as spanners nut 2 is slowly screwed again and enter the fixed position until valve guide bushing and assembly 12 and get final product and (adopt the structure of screw thread 14 and nut 15 as positioner, using method is the same, just the microcephaly with the screw thread positioning instant can).
