Abstract
The invention relates to a diesel engine cylinder sleeve wearing ring. Grooves are uniformly formed in the inner wall of the diesel engine cylinder sleeve wearing ring, arms corresponding to the grooves are arranged on a bracket of a dismounting tool of the diesel engine cylinder sleeve wearing ring, ejector robs with return spring mechanisms are arranged in the arms, a guide rod is fixed at the center of the bracket, a cam and a hand wheel are fixedly integrated and can rotate by taking the guide rod as centers, the ejector robs are simultaneously and radially ejected, a hammer block is sleeved on the guide rod and can slide up and down along the guide rod, and a stop nut is located at the top end of the guide rod. According to the diesel engine cylinder sleeve wearing ring and the dismounting tool of the diesel engine cylinder sleeve wearing ring, the dismounting of the wearing ring is benefited, the working efficiency is improved, and the damage probability of the wearing ring in the dismounting process is reduced.
Description
Technical field
The invention belongs to Diesel Engine Technique Field, relate in particular to a kind of cylinder jacket of diesel engine wearing ring and extracting tool thereof.
Background technology
The cylinder jacket of a lot of diesel engine using wearing ring versions.In assembling with repair in the process such as this cylinder jacket, rely on operator's hand disassembly fully.Because the gap of wearing ring and cylinder liner internal wall installing hole is very little, when relying on operation author hand disassembly, be difficult to wearing ring is removed from cylinder jacket.Particularly used cylinder jacket can have carbon distribution and greasy filth in the gap between cylinder jacket top and cylinder jacket and wearing ring, so just more is difficult to remove wearing ring, even can cause the damage of wearing ring in demolishing process.
Summary of the invention
Purpose of the present invention overcomes the deficiency of above-mentioned prior art exactly, and a kind of cylinder jacket of diesel engine wearing ring and extracting tool thereof are provided, so that dismounting reduces and damages.
The object of the present invention is achieved like this: a kind of cylinder jacket of diesel engine wearing ring is characterized in that inwall is provided with equally distributed groove.
In order to realize purpose of the present invention, a kind of cylinder jacket of diesel engine wearing ring extracting tool, it is characterized in that the arm corresponding with described groove arranged on the support, be provided with the push rod with the return spring mechanism in the arm, guide rod is fixed in the center of support, cam and handwheel are fixed as one, can rotate centered by the guide rod, push rod is prolonged radially eject simultaneously, the hammer piece is enclosed within on the guide rod, can prolong guide rod and slide up and down, stop nut is positioned at the guide rod top.
Adopt the solution of the present invention, made things convenient for the dismounting of wearing ring, improved operating efficiency, and reduced the probability that wearing ring damages in the unloading process.
Description of drawings
Fig. 1 is the cylinder jacket of diesel engine wearing ring extracting tool structure front elevational schematic of the embodiment of the invention.
Fig. 2 is the cylinder jacket of diesel engine wearing ring extracting tool structure top cross-sectional view of the embodiment of the invention.
Number in the figure: the 1-wearing ring, the 2-groove, the 3-support, the 4-return spring mechanism, the 5-push rod, the 6-cam, the 7-handwheel, the 8-guide rod, 9-hammers piece, 10-stop nut into shape.
The specific embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
Referring to Fig. 1 and Fig. 2.The cylinder jacket of diesel engine wearing ring of present embodiment is established three equally distributed grooves 2 on the inwall.The cylinder jacket of diesel engine wearing ring extracting tool of present embodiment has three the equally distributed arms corresponding with the groove 2 of wearing ring 1 on the support 3.Be provided with the push rod 5 with return spring mechanism 4 in each arm.Guide rod 8 is fixed in the center of support 3.Cam 6 and handwheel 7 are fixed as one, and its borehole jack can rotate centered by the guide rod 8 on guide rod 8, three push rods 5 are prolonged radially eject simultaneously.Hammer piece 9, can prolong guide rod 8 and slide up and down on guide rod 8 by borehole jack.Stop nut 10 is positioned at the guide rod top.
During the dismounting wearing ring, the wearing ring extracting tool is put into the wearing ring endoporus, with the groove position that push rod 5 is aimed on the wearing ring, then rotation hand wheel 7, and the cam that drives the handwheel bottom is released push rod 5, inserts in the groove 2 of wearing ring 1 endoporus; Quick upward sliding hammer piece 9, bump stop nut 10 utilizes impact that wearing ring 1 is extracted from cylinder jacket.After the dismounting, backward rotation handwheel 7, return spring mechanism 4 make in the push rod 5 retraction support arms.
It should be noted that at last: above embodiment only in order to technical scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of various embodiments of the present invention technical scheme.
