Abstract
The utility model discloses a valve oil seal disassembly tooling, which comprises a pull rod and a sleeve, wherein an axial through hole is arranged in the sleeve, the pull rod is arranged in the axial through hole, a head end surface of the pull rod is provided with a counter bore, the wall of the counter bore is divided into four clamping jaws in equal, and the clamping jaws outwardly lean from a root portion. The design leads the disassembly work of oil seals to be easy and save labor, avoids damaging the oil seal, and leads the oil seal to be secondarily usable. The valve oil seal disassembly tooling is simple in structure and convenient in making, can be widely applied to manufacturers or maintenance shops, and reduces the labor strength of operators.
Description
Technical field
The utility model relates to automobile assembling frock field, especially relates to a kind of frock that is used to dismantle the automotive engine valves oil sealing.
Background technology
In the assembling process of automobile engine cylinder head, need press-fit valve oil seal, in press-fiting process if quality problems or press-fit mistake need to remove valve and press-fit again.In addition,, also need to remove valve oil seal, press-fit again again after repairing at some engines of reprocessing.Owing to after valve oil seal is fitted on the valve guide bushing certain magnitude of interference is arranged, and,, often adopt destructive the dismounting simultaneously when the dismounting valve oil seal so operating personnel require great effort very much owing to lack the specific purpose tool of removing usefulness, make oil sealing to reuse, cause waste.Have some oil seal removers can improve the efficient of dismounting now, but most dismounting Workpiece structure complexity is made difficulty, has brought certain restriction to practical application.The Chinese utility model patent specification of the CN2768985Y that on April 5th, 2006 was announced discloses a kind of oil sealing stripping attachment, this stripping attachment comprises parts such as pull bar, spring, jaw, jaw fixed cover and fixed supporting seat, pull bar also need insert in the middle of the jaw and pass axis hole in the middle of jaw fixed cover, the fixed supporting seat after flexibly connect with a cam.This oil sealing stripping attachment can reduce labor intensity of operating personnel, increases work efficiency.Yet the complex structure of this stripping attachment is made comparatively difficulty, and extensive use has certain limitation in operating personnel.
The utility model content
The utility model mainly is to solve the oil seal remover complex structure that exists in the prior art, make the comparatively problem of difficulty, a kind of valve oil seal dismounting frock is provided, this tool structure is simple, easy to make, and can guarantee to improve the removal efficiency of oil sealing under the not impaired prerequisite of oil sealing.
In order to solve the problems of the technologies described above, the utility model has adopted a kind of like this valve oil seal dismounting frock, comprise pull bar and sleeve, an axially extending bore is arranged in the described sleeve, described pull bar is arranged in the described axially extending bore, described rod head end face is provided with a counterbore, and the hole wall of described counterbore is divided into four jaws, and described jaw is outward-dipping from root.Dismounting is during valve oil seal, entangles oil sealing with the counterbore of rod head, and operating personnel one hold pull bar, another hand is the pushing sleeve tube forward, because four jaws are outward-dipping from root, under the effect of sleeve, jaw is inwardly gathered oil sealing formation clamping force, at this moment pull back just again oil sealing is pulled down from valve, after oil sealing is pulled down, pushing drawing rod forward, jaw is pushed out in sleeve, naturally open, oil sealing just comes off in counterbore.Design makes that the dismantlement work of oil sealing is light laborsaving like this, and can not destroy oil sealing, and oil sealing can be used by secondary.And this oil sealing dismounting tool structure is simple, easy to make, can be widely used in manufactory or maintenance shop, alleviates operator's labour intensity.
As preferably, after leaning on, the middle part of described pull bar outer wall on the position collar groove is set, and collar groove rear portion forms handle, in the collar groove collar is set.Collar is set on pull bar can prevents not only that pull bar from skidding off in the sleeve and come off, and the collar rear portion forms handle, the hand griping position for the operator provides a safety is difficult for crushing hand in operating process.
As preferably, anti-slip tank is set at described handle outer wall.The handled easily person operates like this, and hand is difficult for sliding from pull bar, is convenient to firmly.
As preferably, the forward crossette that is provided with in described sleeve middle part is provided with the collar groove at the afterbody of sleeve outer wall, and bush outer sleeve connects one and holds cover, in described collar groove collar is set.Connect one at bush outer sleeve and hold cover, hold cover and can do axially-movable on sleeve, because the forward crossette that is provided with in sleeve middle part, afterbody is provided with collar, and holding cover can be from landing on the sleeve.In operating process, only need to entangle oil sealing with counterbore earlier like this, one holds pull bar, another holds holds cover, knocks crossette forward sleeve is moved forward, and sleeve is to jaw action like this, make jaw inwardly gather the clamping oil sealing, pull bar is pulled back just and oil sealing can be left behind.On sleeve, increase and hold the labour intensity that cover can alleviate the operator, make operation easier.
As preferably, anti-slip tank is set at the described cover outer wall of holding.The handled easily person operates like this, and hand is difficult for sliding from holding to put, and is convenient to firmly.
The beneficial effects of the utility model are that this valve oil seal dismounting tool structure is simple, easy to make, can guarantee to improve the removal efficiency of oil sealing under the not impaired prerequisite of oil sealing.Make the utility model can be widely used in manufactory or maintenance shop, alleviate operator's labour intensity.

Fig. 2 is the structural representation of pull bar;
Fig. 3 is the structural representation of sleeve;
Fig. 4 is the right view of Fig. 2.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
As shown in Figures 1 to 4, valve oil seal dismounting frock of the present utility model comprises sleeve 6, pull bar 1 and holds cover 3.Be provided with an axial through hole 9 in the described sleeve 6, at the forward crossette 5 that is provided with in the outer wall middle part of sleeve 6, the rear portion is provided with collar groove 10.The front end face of described pull bar 1 is opened a counterbore 11, the hole wall of counterbore 11 is divided into four jaws 7, and jaw 7 is outward-dipping from heel, and the middle part of pull bar 1 outer wall is by being provided with collar groove 10 on the position, back, the rear portion of collar groove 10 forms handle 8, and anti-slip tank 4 is set on the outer wall of handle 8.Hold cover 3 and be the pipe shape, on the outer wall of the cover 3 that is in one's hands anti-slip tank 4 is set equally.Sleeve 6 is passed in the rear end of pull bar 1, will hold cover 3 again and pass the trombone slide rear sleeve and be connected on the sleeve 6, last the collar groove 10 of pull bar 1 and sleeve 6 in installation collar 2.
During the dismounting valve oil seal, operating personnel one hold Pulling-rod handle, and one holds and holds cover, entangle oil sealing with the counterbore of rod head, right hand promotion is held and is overlapped the crossette that knocks on the sleeve then, sleeve is travelled forward, because the jaw of rod head is outward-dipping from root, so under the effect of sleeve, jaw inwardly closes up the clamping oil sealing, then pull bar is pulled back, because the jaw of rod head has clamped oil sealing, just can extract oil sealing this moment from valve.Extracting the back only needs just can unclamp jaw with holding the collar that cover knocks on the sleeve, oil sealing easily can be taken out.
This valve oil seal dismounting tool structure is simple, easy to make, can guarantee to improve the removal efficiency of oil sealing under the not impaired prerequisite of oil sealing.Make the utility model can be widely used in manufactory or maintenance shop, alleviate operator's labour intensity.
